  • Stalking your favorite celebrities with Office 365 Connectors for Groups

    Office 365 Connectors are a new extensibility point for Groups.  They provide a way to pull in information from various sources such as Twitter, Bing News, and Trello.  The information they provide will be dumped right into your group’s inbox.

    Office 365 Connectors for Groups are new.  Really new.  So new in fact that you have to enable them with a special query string parameter, EnableConnectorDevPreview=true.  The easiest way to enable them is to go the URL below.

    When you go to the URL below, you’ll see a new option for Connectors under the … menu of your group.


    There, you will see a list of all connectors currently available.  This includes things like Bing News, Twitter, JIRA, RSS, Trello, Github, and a few others.


    Since we are looking to stalk celebrities, we’ll make use of the Twitter and Bing News connectors.  I want to know any time, the celebrities I am stalking send a tweet out.  When they do tweet something, what they say will automatically be delivered to my Group’s inbox.  If you are subscribed to the Group the will end up in your inbox as well.

    Let’s add the Twitter connector.  The first thing you will need to do is add an account if you haven’t provided one yet.  Sign-in with your credentials to proceed.


    Now, let’s configure the celebrities we want to stalk.  By adding their twitter handles (minus the @) separated by commas.  You can only enter up to 50 characters in the box, so if you have lots of people to stalk, you can just add another instance of the Twitter connector.


    You can also Track hashtags this way as well as mentions and retweets.  It’s fairly versatile.  When you are done, click the Save button.  When you click it, it will give you no response and just wait there for a few seconds.  Remember this is a developer preview.  If you click it multiple times, you will end up getting multiple connectors, so just be patient. 

    Now, I want to see whatever they say in the news about my celebrities so I am going to add a Bing News Connector.  This will give you a digest once a day of whatever terms you ask it to search on.  Here I have used the Bing News Connector to send me the latest on Neil Patrick Harris.


    Once you are done adding connectors, you can see the ones you added on the Connectors page.  You can reconfigure them here as needed as well. 


    When you return to your group inbox, there will be notifications that your connectors are active.


    Now, you just wait until your celebrities make their move (and for the connectors to fire).  When I first configured them last week, they didn’t work.  Remember, we are in a developer preview.  They are started working yesterday and the data started coming in bulk (and so did the notifications).  In my experience today, the twitter connector usually delivers tweets within 5 minutes of when it occurred.  The Bing News connector delivers a digest whenever it feels like.  I’m not really sure what time zone it is executing in but I assume it’s the local one.

    After your connectors have started providing data, here is what it looks like.  For example, here is the twitter connector providing Wil Wheaton’s latest tweet.  You’ll get one entry in the inbox for each tweet.  The formatting of URLs, usernames, and hashtags could use some improvement, but all of the information is there.


    Here is what the results look like in Outlook 2016.


    It’s up to the connector to provide the formatting, so you can see the results from Bing look a bit different.


    All kidding aside, I hope you can see the power of Office 365 Connectors.  Instead of stalking celebrities, you could use this same technique to quickly provide information about company’s competitors right to your inbox.  There is also a developer story using Webhooks.  The last I checked the URL it provided me didn’t work yet, but we can expect it is coming soon.  Office 365 Connectors are powerful and I am looking forward to using them more.

    I hope you found this look at Office 365 Connectors useful.  Happy stalking!

  • Drag and Drop into Office 365 comes to Edge on Windows 10

    Looking back to the SharePoint 2013 launch, drag and drop into a document library was one of the hit features.  As many of us have transitioned to Office 365, it’s a feature we expect to be there in our document libraries and OneDrive.  However, when Windows 10 was released at the end of July, the feature was noticeably missing from Microsoft’s newest browser, Edge.  Drag and drop support didn’t work in Office 365, OneDrive, or anywhere else for that matter.

    With the Threshold 2 (TH2) fall update for Windows 10 last week, we now have drag and drop support.  For Windows Insiders, this support has been there in preview builds for a while but it hasn’t been talked about much.


    Say what you want about Edge, I have had pretty good luck with it.  Some people act like it is completely unusable, but I can get most of my day to day tasks done with it.  I’ve used it to replace Google Chrome for almost all of my tasks.  Does it still have issues and does it still need more features?  Absolutely, but it gets the job done for the most part.  If you have discounted it before, give it another try.  It’s constantly being updated.

    One cool feature that came with the fall update is the ability to cast media to a device directly from Edge.  What this means is that when you visit a page with a video on it, you can select cast to device in the menu and choose any Miracast or DLNA supported device to view that content on the remote screen. 

    If you’re not familiar with Miracast, it lets your wireless transmit what’s on your screen to a TV or monitor.  This is included in a lot of devices now such as the Roku.  You can also pick up a Microsoft Wireless Display Adapter as well.  What’s nice is that you can cast a video to a TV from your Windows 10 device and you can still use it while the video is showing.  With Miracast support before, you had to project your entire desktop or extend it just like you did with an external monitor.


    I think it’s a useful feature.  Similar to what Chromecast has been doing for some time now.  However, Miracast is a more open standard and supported across a variety of devices.  The nice thing is that it doesn’t require any additional drivers, plugins, or software to make it work.

  • SharePoint 2016 installation first look

    Today Microsoft released the IT Preview of SharePoint 2016.  We’re going to look at the install process today and point out any differences between previous versions of SharePoint.  You can find out more about SharePoint 2016 from the Office blog post.


    I created a new virtual machine running on Windows 10 Hyper-V.  This virtual machine is running Windows Server 2016 Technical Preview 3.  On this server, I have promoted it to a domain controller using Active Directory Directory Services.  I have also installed SQL Server 2014 R2.

    Installation of SharePoint 2016 IT Preview looks similar to previous SharePoint installations.  When you mount the ISO, you will see a familiar splash screen.


    Installing the prerequisites

    The prerequisite installer looks similar to previous versions.  Click Next to continue.


    Accept the license terms.


    Wait and home it finishes successfully.


    Installation of the SharePoint 2016 IT Preview prerequisites is just as troublesome as previous versions.  I managed to generate a few errors and never did get it to agree the role was successfully installed.  I had to install the Visual Studio 2013 Redistributable myself.  There is a work-around for getting around the IIS role configuration step on the Known Issues in SharePoint Server 2016 Preview page.


    SharePoint 2016 Installation

    The installation is quick and easy.  It also looks similar to other versions.  Start by entering the product key.  Remember this was found on the SharePoint 2016 download page.


    Next, accept some more license terms.


    Specify the install location for your search index.  You can just use the defaults for this preview installation.


    Wait for the installation to complete.


    When installation completes, you will be prompted to run the Configuration Wizard.


    Running the Configuration Wizard

    The Configuration Wizard also looks similar but has a few changes.  Click Next to proceed.


    Now, create a new farm.


    Then, specify your farm passphrase.


    Specify your farm account, SQL Server name and database.


    This new screen allows you use the new MinRole feature. MinRole simplifies the server architecture of SharePoint 2016.  In this case, we are going to use a Single Server Farm (which shouldn’t be as bad as previous versions).


    Specify the details for Central Administration.


    Confirm your settings.


    When it finishes, you are ready to try out Central Administration.


    Now, we can start our configuration.


    That’s a quick look at the installation process of SharePoint 2016 IT Preview.  Be on the look out for my next posts covering changes in Central Administration and the UI.

  • How to: Play an Office 365 Video from a Universal Windows App in Windows 10

    I’ve had a personal interest in figuring out how to play videos from the Office 365 Video Portal in a Univeral Windows App (UWP) in Windows 10 since Microsoft Ignite.  In reality, the process isn’t that difficult, but there wasn’t a lot of details out there on how to put the pieces together until recently.  Today, I am going to walk you through how to retrieve the first video in a channel and play it using a MediaElement

    Today, I combined elements I learned from Richard DiZerga’s Universal App blog post, Chakkradeep Chandran’s Ignite session, as well as Andrew Connell's MVC Sample.  Special thanks to all of them for having the pieces I needed to put all of this together.  Since this is a Universal app it should work across multiple devices in theory.

    This app could easily be extended to create a nice interface to browse a channel and pick a video.  If you’re familiar with data binding in WPF though that shouldn’t be hard for you, so I won’t cover that today.  We’re simply going to look at the necessary API and REST calls to get the secure playback URL.  Once we have that URL, we can have the MediaElement start playing the video.

    Getting started

    First, you’ll need to have installed Windows 10 as well as the final version of Visual Studio 2015.  We’re also assuming you have an Office 365 tenant, the Video Portal turned on, and you have some videos uploaded.  If you have never created a Universal Windows App before you can find it under your favorite programming language –> Windows –> Universal –> Blank App (Universal Windows).


    Playing a video from the Office 365 Video Portal involves several steps.  If you know some of the values already along the way (such as the Video Portal URL), you can skip some steps.  I am going to include all of them (which means this blog post is going to be long).  The steps we need to go through are:

    1. Authenticate with Azure Active Directory / Office 365
    2. Access the Discovery Service to get the RootSite ServiceResourceId
    3. Determine the Video Portal Hub Url (i.e.:
    4. Get the list of channels
    5. Get the videos inside a channel
    6. Get the video playback URL

    As you can see, that’s a lot of service calls.  Caching is a good thing.

    Connecting to Office 365

    There are no shortage of ways to authenticate with Office 365 and Azure Active Directory.  Windows 10 introduces a new way called the Web Account Provider.  This will provide us our token that we can pass to the Discovery Service as well as give us tokens to other services such as SharePoint or Outlook.  It will prompt the user to enter his or her credentials if we don’t have a token yet as well.

    To connect to Office 365 bring up the context menu on the project in Solution Explorer and choose Add –> Connected Service.  Select Office 365 APIs and then click Configure.


    The nice thing about the Connected Service dialog in Visual Studio 2015 now is that it takes care of all of the manual Azure Active Directory application setup.  You don’t need to go manually copy a ClientId, secret, permissions, or anything.  This makes the new developer experience much better.

    Now, you need to specify the domain of your tenant (i.e.:


    Clicking Next will prompt you for authentication.  Enter your Office 365 credentials and then you can proceed to the next step.


    Now, we need to tell Visual Studio to Create a new Azure AD application to access Office 365 API services.  This will register the new application in Azure AD and then we can request permissions.


    On the next six steps of the Wizard, we set the permissions that the app requires.  For the purpose of playing a video, we don’t need access to Calendar, Contacts, Mail, or My Files.  For Sites, we need the following permissions:

    • Read and write items and lists in all site collections
    • Read and write items in all site collections
    • Read items in all site collections


    For Users and Groups, select the following permissions:

    • Sign you in and read your profile


    Finally, hit Finish and Visual Studio will add the connected service to your project.

    Designing the Page Layout

    Now we’ll edit MainPage.xaml and add our controls to it.  I kept this simple by just adding a Button control and a MediaElement.  You can arrange them as you like.


    Authenticating with Web Account Manager

    Before we get too far, I am going to create a folder for the Models.  I am going to skip a formal Controller class today since we’re not doing any real data binding.  Normally you would have multiple controllers to pull up a list of channels, videos, etc.  We’ll use a repository class, VideoRepository, that will connect to Office 365 and retrieve our data and our models we’ll use to deserialize the jSon that comes back from the REST API. 

    The VideoRepository class will also handle authentication.  We’ll add the following using statements.

    using System.Net.Http;

    using System.Net.Http.Headers;

    using Microsoft.Office365.Discovery;

    using Microsoft.Office365.SharePoint.CoreServices;

    using Windows.Security.Authentication.Web.Core;

    using Windows.Security.Credentials;

    using Newtonsoft.Json;

    The first method we will create is GetAccessTokenForResource.  If you have looked at other Universal App Samples, this should look fairly similar.  The purpose of this method is to attempt to get a token silently (without prompting the user).  If it can’t, then it it will show the the Office 365 login and the user can login which will provide the token. 

    public async Task<string> GetAccessTokenForResource(string resource)


        string token = null;


        //first try to get the token silently

        WebAccountProvider aadAccountProvider

            = await WebAuthenticationCoreManager.FindAccountProviderAsync("");

        WebTokenRequest webTokenRequest

            = new WebTokenRequest(aadAccountProvider, String.Empty, App.Current.Resources["ida:ClientID"].ToString(), WebTokenRequestPromptType.Default);

        webTokenRequest.Properties.Add("authority", "");

        webTokenRequest.Properties.Add("resource", resource);

        WebTokenRequestResult webTokenRequestResult

            = await WebAuthenticationCoreManager.GetTokenSilentlyAsync(webTokenRequest);

        if (webTokenRequestResult.ResponseStatus == WebTokenRequestStatus.Success)


            WebTokenResponse webTokenResponse = webTokenRequestResult.ResponseData[0];

            token = webTokenResponse.Token;


        else if (webTokenRequestResult.ResponseStatus == WebTokenRequestStatus.UserInteractionRequired)


            //get token through prompt


                = new WebTokenRequest(aadAccountProvider, String.Empty, App.Current.Resources["ida:ClientID"].ToString(), WebTokenRequestPromptType.ForceAuthentication);

            webTokenRequest.Properties.Add("authority", "");

            webTokenRequest.Properties.Add("resource", resource);


                = await WebAuthenticationCoreManager.RequestTokenAsync(webTokenRequest);

            if (webTokenRequestResult.ResponseStatus == WebTokenRequestStatus.Success)


                WebTokenResponse webTokenResponse = webTokenRequestResult.ResponseData[0];

                token = webTokenResponse.Token;




        return token;


    Let’s look at some of the highlights.  First we get our aadAccountProvider by calling WebAuthenticationCoreManager.FindAccountProviderAync().  This is the call into the Web Account Manager that I have been talking about.  You always pass it the (at least for this exercise).  We then need a WebTokenRequest.  This is where the ClientId of the application comes in.  Remember Visual Studio created this for us when it registered our app with Azure Active Directory.  The resource property is where we pass in the Uri to the service we want to access.  On our first call this will be the Uri of the discovery service.  On subsequent calls it will be the Uri we get for accessing things in SharePoint.

    Next, the method tries to silently authenticate the user.  This method would return with a Success result if the user has authenticated inside this application before. 

    WebTokenRequestResult webTokenRequestResult

        = await WebAuthenticationCoreManager.GetTokenSilentlyAsync(webTokenRequest);

    If the user already has a token, then we are done.  Otherwise user interaction is required. The RequestTokenAsync call on the WebAuthenticationCoreManager is what actually prompts the user for credentials.  Ultimately, this method returns a token for the resource you asked for.  When we run the application and click the Play button, it will prompt us for credentials.


    After you authenticate, you will get prompted to grant permissions to the app.  These will match the ones we specified earlier when adding the Connected Service.


    Calling the Discovery Service

    We’re going to call the Discovery Service to determine the ServiceEndpointUri for the RootSite capability. We’ll do this in a new method called GetSharePointServiceEndpointUri. We do this by accessing for an access token from our GetAccessTokenForResource passing the URL

    string accessToken

        = await GetAccessTokenForResource("");

    DiscoveryClient discoveryClient = new DiscoveryClient(() =>


        return accessToken;


    After we get a DiscoveryClient, we can call DiscoverCapabilityAsync.  This method also stores the access token used for accessing resources in the variable sharePointAccessToken.  It also stores the ServiceEndpointUri in the variable sharePointServiceEndpointUri.  We’ll use this URI for the subsequent REST calls.

    CapabilityDiscoveryResult result = await discoveryClient.DiscoverCapabilityAsync("RootSite");

    sharePointAccessToken = await GetAccessTokenForResource(result.ServiceResourceId);

    sharePointServiceEndpointUri = result.ServiceEndpointUri.ToString();


    return sharePointServiceEndpointUri;

    Remember, the full source code is available in GitHub.

    Get the Video Portal Hub URL

    If you have worked with Office 365, you probably know that it’s pretty easy to guess what the URL to the Video Portal Hub will be (the hub is the root site collection of the Video Portal).  Since we want to do things right though, we’ll go through the Video Service’s Discover endpoint to determine the URL.  In fact, once we construct these next two methods, the rest will be very similar.

    We’ll create a new method called GetVideoPortalHubUrl.  The first thing we’ll do is call GetSharePointServiceEndpointUri to authenticate and return us the endpoint for working with SharePoint.  We append VideoService.Discover to the Uri returned by our method.  How did we know this was the URL, it’s in the Video REST API reference (still in preview).

    var requestUrl = String.Format("{0}/VideoService.Discover", await GetSharePointServiceEndpointUri());

    We then, create a function that returns an HttpRequestMessage using the requestUrl.

    Func<HttpRequestMessage> requestCreator = () =>


        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requestUrl);

        request.Headers.Add("Accept", "application/json;odata=verbose");

        return request;


    Then, we create a new httpClient and pass it, our access token, the HttpClient, and the RequestMessage to a custom method we will build named SendRequestAsync.   This piece is based upon other’s code so I didn’t really tweak it since it works.  After our call to that method, we’ll deserialize the jSon that comes back.  I borrowed several of AC’s helper classes from his MVP example here.

    Let’s take a look at SendRequestAsync.  We’ll start with a using blog to get our HttpRequestMessage

    using (var request = requestCreator.Invoke())

    We’ll then need to add the necessary headers.  First, we add an AuthenticationHeaderValue with the sharePointAccessToken we got earlier.  We also add another header, X-ClientService-ClientTag.  I don’t know if this is required but Chaks included it in his examples.  I updated the version to match the current version reported in the Connected Service wizard.

    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

    request.Headers.Add("X-ClientService-ClientTag", "Office 365 API Tools 1.5");

    Then we invoke the request using httpClient.

    var response = await httpClient.SendAsync(request);

    The method then returns the response assuming it’s successful.  The example that Chaks provided will actually make a second attempt to call the service if the user isn’t authorized.  You can optionally include that if you like.

    Now going back to our GetVideoHubUrl method after we successfully got a response back.  We now need to parse the JSON that came back into a usable object.  This is where Newtonsoft.Json comes in.  We use the models that AC provided in the MVC project. In this case we serialize the responseString into an object of VideoServiceDiscovery.  Now, we can get the VideoPortalUrl for our subsequent REST calls.

    string responseString = await response.Content.ReadAsStringAsync();

    var jsonResponse = JsonConvert.DeserializeObject<VideoServiceDiscovery>(responseString);

    videoPortalUrl = jsonResponse.Data.VideoPortalUrl;

    Get the video portal channels

    Now that we have our Video Portal Hub URL, we can retrieve the list of channels.  The Video REST API Reference tells us we need to append /_api/VideoService/Channels to the Video Portal Hub URL which we just retrieved.  We’ll create a new method called GetVideoChannels which will look similar to GetVideoPortalHubUrl expect the requestUrl used and the JSON serialization.

    var requestUrl = string.Format("{0}/_api/VideoService/Channels", videoPortalUrl);

    Since we return multiple channels, we loop through the results and add new VideoChannel objects to the list. 

    string responseString = await response.Content.ReadAsStringAsync();

    var jsonResponse = JsonConvert.DeserializeObject<VideoChannelCollection>(responseString);


    var channels = new List<VideoChannel>();


    foreach (var videoChannel in jsonResponse.Data.Results)


        var channel = new VideoChannel


            Id = videoChannel.Id,

            HtmlColor = videoChannel.TileHtmlColor,

            Title = videoChannel.Title,

            Description = videoChannel.Description,

            ServerRelativeUrl = videoChannel.ServerRelativeUrl




    At this point, you have enough data you can start doing some data binding.  As I mentioned earlier, I am skipping that since data binding in a Universal Windows App for Windows 10 is quite similar to what was there in Windows 8.1  For our example, I am simply going to pass the Channel Id into our next method to retrieve a list of videos.

    Getting the list of videos in a channel

    Now that we have a list of Channels, we can make another Video REST API call to get a list of videos in our new method GetVideos.  We build our requestUrl by appending /_api/VideoService/Channels(‘<channelid>’)/Videos.  Remember we got the Channel Id from our last API call.  Now this simply returns the metadata about the video.  After this, we still have one more call to get the Playback URL.

    var requestUrl = string.Format("{0}/_api/VideoService/Channels('{1}')/Videos", videoPortalHubUrl, channelId);

    The rest of the method is similar to GetVideoChannels

    Get the video playback URL

    For the purpose of our example, we’re also going to simply play the first Video in the Channel.  To get the Playback URL, we’ll need the Video Id as well as the Channel Id we retrieved earlier.  When it comes to streaming, we have a choice of either Smooth Streaming or HLS Streaming by specifying the streamingFormatType parameter on the Video REST API call.  HLS streaming requires one fewer API call so we are going to use that for the example today.  You may want to use Smooth Streaming for your application.  To use HLS Streaming, specify a value of 0.

    var requestUrl = string.Format("{0}/_api/VideoService/Channels('{1}')/Videos('{2}')/GetPlaybackUrl('{3}')",

        new string[] { videoPortalHubUrl, channelId, videoId, streamingFormatType.ToString() });

    The REST call will return a playback URL which we can then assign to the MediaElement

    Playing the video

    On the click handler of the Play button we added in the beginning, we make our calls into the VideoRepository class.  Once we get the Playback URL we binding it to the MediaElement and the video will start playing.  I also set a few parameters to turn on the transport controls and enable full screen mode.  You can set those as you like.

    private async void button_Click(object sender, RoutedEventArgs e)


        VideoRepository videoRepository = new VideoRepository();

        string videoPortalUrl = await videoRepository.GetVideoPortalHubUrl();

        var videoChannels = await videoRepository.GetVideoChannels();

        string channelId = videoChannels[0].Id;

        var videos = await videoRepository.GetVideos(channelId);

        string videoId = videos[0].VideoId;

        var videoPlayback = await videoRepository.GetVideoPlayback(channelId, videoId, 0);


        mediaElement.Volume = 0;

        mediaElement.AreTransportControlsEnabled = true;

        mediaElement.IsFullWindow = true;

        mediaElement.Source = new Uri(videoPlayback.Value);


    There you have it a (somewhat) quick and dirty way to play a video from the Office 365 Video Portal in Windows 10.  This should work on Windows 10 Mobile as well.  Here is what our app looks like when playing a video.


    Source Code

    As promised the source code is available on GitHub.  I may extend it in the future to include all of the data binding and improve the look.  Feel free to contribute to the repo as well.  If you make use of any of the code, you’ll want to add error handling of course.

    Feel free to ask me any questions by leaving a comment.

  • Moving the blog to Azure and the origin of

    When we built, we used one of the most common blog engines around Community Server by Telligent.  At the time Telligent had a great blogging platform that they provided free to technical bloggers.  They really did a service to the community.  Then one day, they decided to drop the free product and start charging for new versions even for community bloggers.  Now, people barely even remember the name Telligent and for good reason.  Cloud offerings like with their freemium model moved in and took over.

    Moving to Azure

    That said, my blog has been running on a Windows Server 2003 virtual machine with only 2 GB of ram since 2006 or so.  As old as my version of Community Server is now, it still works pretty well.  It did come out before the days of mobile devices so the master page I have could use some work.  It’s been serving up blog posts for years though without issue.

    The virtual machine was hosted with my old employer, Isocentric Networks.  Isocentric is a small data center based in Tulsa, OK.  I learned all about racking, networking, and hosting while I worked there.  They have been nice enough to let me host my blog there all of these years.  I am truly thankful.

    With Window Server 2003 no longer being supported as of last month though, it was time for the blog to move.  I created a new Windows Server 2012 R2 virtual machine in Azure and copied the database and everything over.  I was a little fearful that I might not be able to get Community Server to work in the new environment, but everything worked just fine.  I just created a .NET Framework 2.0 application pool and configured a new web site in IIS and everything worked fine.

    Now, I have pointed the DNS entry for the site over to the Azure Virtual Machine and things seem to be running great.  If you see an issue, feel free to ping me on twitter @coreyroth.

    Why DotNetMafia?

    Over the years, many people have asked why DotNetMafia?  Well as with a lot of great things in life, the concept started while a few of us were sitting around at the bar for happy hour one day.  We were telling stories about how there were some recruiters in town that were less than professional.  Back then it wasn’t uncommon for a recruiter to lie to your face, make you lie on your resume, or just sent it to a client without even talking to you first.  We wanted to build a web site where we could rate recruiters and people could go talk about the good and bad things recruiters did.  So Kyle Kelin (a.k.a. theGodfather), came up with the concept and name.  Like all of the billion dollar ideas, we came up with back then, we only got about as far as purchasing the domain name. 

    A lot of us were changing jobs back then (hence the recruiter thing).  I actually started the blog internally when we were all working at Dollar Thrifty Automotive Group.  .NET Framework 2.0 was in beta and I started it to teach the development team I led about the new features that were coming.  Back then it was simply called Corey’s .NET Tip of the Day.  It really wasn’t a blog though, it was really just an announcements list in SharePoint 2003.  I wasn’t really working with SharePoint much back then, but I thought it was a good tool at the time for what we were trying to accomplish.

    When I left Dollar Thrifty at the end of 2005, I wanted to keep the content going so I moved it to a virtual machine I had at Isocentric Networks and hosted it at  I actually exported the contents of my announcements list into Excel and then imported into a SQL Server database.  I wrote my own custom blogging engine at the time and I used it for a while.

    Now a year or so later, a few of the other ex-employees of Dollar Thrifty wanted a place to blog too.  Tony Kilhoffer set up a SharePoint 2003 server and I tried to use the blog platform there.  Unfortunately, we couldn’t ever get the content quite right so we gave up. 

    Then we ended up with Community Server.  The nice thing about Community Server was it had the ability to import content from an RSS feed.  This made bringing in all of my old content quite easy.  If you look around the blog, you’ll notice we host for six different people: Cory Robinson, Kyle Kelin, James Ashley, Tony Kilhoffer, Kevin Williams, and myself.  None of them really blog much any more, but their content is still there.  We had all of the bloggers, but what were we to call this new site?  A cheesy name that has worked well for us.

    Why not move to a new blogging platform?  I definitely want to but it is a bit of a challenge.  Moving the content to another platform isn’t that difficult.  However, maintaining the existing URLs when moving to a new platform is difficult.  If I don’t maintain them, I’ll break the SEO of the site.  My top post every month is years old and talks about using PowerShell with SharePoint 2010.  The SEO is important so before I migrate anywhere, I need to have a solid solution to maintain those links.

  • Fixing Office 365 ProPlus Activation Prompts on Windows 10

    If you are using Office 365 to deploy Office 2016 Preview (Office 365 ProPlus) to your desktop, you may have found that you get hit with multiple prompts to activate the product even though it is already activated.  You can click Cancel on the Activation but it will prompt you again when you open up any other Office product.


    @MarioFulan on twitter mentioned that performing an Online Reset corrects this issue.  In Windows 10, you will need to go to the old control panel to launch the repair process (otherwise you’ll just uninstall the product).  Choose Online Repair.


    If you haven’t installed Office 365 ProPlus in a while, they have actually updated it for Windows 10.  When applications are available, you can click the Open button to start using them.


    When the process is done, you’ll notice some new prompts showing you how to launch Office.  It will also pin many of the Office apps to your taskbar.


    Once the process is complete, you shouldn’t be prompted with all of the activation prompts.

  • Working with Office 365 Groups using PowerShell

    New features are coming fast to Office 365 Groups.  As administrators we have been looking for ways to simplify the management of groups.  This includes functions like adding groups, deleting groups, and adding members to groups.  At Ignite last week in session BRK3114 they showed us some of the new PowerShell cmdlets available to make this happen.  There isn’t any documentation on this stuff at all yet, so I wanted to show you some of the stuff that was showed at the conference.

    Establishing a connection to Exchange Online

    Groups are ultimately powered by Exchange (and then SharePoint).  As a result, we make use of the Exchange Online cmdlets.  If you have never used these cmdlets before, we start by creating a session.  Start by opening a PowerShell window of your choice.  We’ll be following the steps provided by TechNet.

    First, get your credentials in PowerShell and store them in a variable using Get-Credential.  A window will pop up prompting you for your credentials.   Use your Office 365 Global Administrator account.

    $userCredential = Get-Credential


    Now, we need to create a session with New-PSSession and pull down the Exchange Online cmdlets.  Executing this command will yield no output.

    $session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirection


    Finally, use Import-PSSession to make the connection.  This takes a few moments as it shows you all of the cmdlets it has loaded.

    Import-PSSession $session


    If you examine the output closely you’ll see some cmdlets for groups in there.  Now we are ready to being working with groups on our tenant.

    Getting a list of all groups

    Let’s start by seeing what groups are present with Get-UnifiedGroup.  Type the following in PowerShell.



    That’s odd.  It returned only one group and I have more than that on my tenant.


    This is because if you have existing groups, they are likely in a state of transition to a new type of object in Azure Active Directory that can be synchronized back to your on-premises Active Directory Domain Services.  This deployment is only temporary though and it may already be working on your tenant.  I created a new one through the user interface today and it showed up.  The one I created months ago did not.

    Creating a new group

    To create a new group with PowerShell, we use the New-UnifiedGroup cmdlet.   Here are the key parameters:

    • DisplayName – display name of the group
    • Alias – alias of the group if you want to override it.  If you omit the parameter, it will generate an alias for you.
    • AccessType – Public or Private
    • AutoSubscribeNewMembers – Add this parameter to auto subscribe new members to the group

    The Members parameter which takes an array of Recipient Ids to add users to the group.  There is also a large number of other parameters that allow you to customize things even further.  I am pretty sure some of these parameters aren’t even configurable in the user interface yet.

    To create a group with minimal parameters, just use the DisplayName parameter:

    New-UnifiedGroup –DisplayName "PowerShell Group 1"


    Unfortunately, since the cmdlets are still under development, this one doesn’t work right now.  However, it might work by the time you try it.

    Adding users to a group

    The cmdlet to add users to a group in PowerShell, Add-UnifiedGroupLinks, actually does work right now.  Here are some of the key parameters:

    • Identity – Alias of the group
    • Links – login or alias of the user being added
    • LinkType – Members, Owners, or Subscribers

    To add a new user to the members group:

    Add-UnifiedGroupLinks groupalias –Links –LinkType Member


    Successful execution will not yield any output.

    To add a new user to the owners group, first add them as a member and then add them as an owner.

    Add-UnifiedGroupLinks groupalias –Links –LinkType Member

    Add-UnifiedGroupLinks groupalias –Links –LinkType Owner


    You can verify that your users are in the group through the Groups user interface.  Note that the user “Joy” is listed as an owner.


    We can also verify the users are in the group via PowerShell.

    Getting the members of a group

    We can use PowerShell to view the members of an existing group with the Get-UnifiedGroupLinks cmdlet.  The key parameters for this cmdlet are:

    • Identity – the alias of the group
    • LinkType – Members, Owners, or Subscribers.  Required.

    To see the members of a group with PowerShell, issue the following command:

    Get-UnifiedGroupLinks –Identity groupalias –LinkType Members


    Removing a user from a group

    You can remove a member from a group using Remove-UnifiedGroupLinks.  Here are the parameters:

    • Identity – alias of the group
    • Links – login or alias of the user to be removed
    • LinkType – Member, Owner, or Subscriber.  Required.

    To remove a user as a member from the group, use the following command:

    Remove-UnifiedGroupLinks groupalias –Links –LinkType Member


    To remove an owner from the group, you will first have to remove he or she from the LinkType Owner.

    Remove-UnifiedGroupLinks groupalias –Links –LinkType Owner

    Remove-UnifiedGroupLinks groupalias –Links –LinkType Member

    Removing a group

    As expected, the cmdlet to remove a group doesn’t function right now either.  We can still look at the syntax though.

    Remove-UnifiedGroup groupalias

    Getting help with the groups cmdlet

    You can type help unifiedgroup to load the help modules for Groups.  When you do, you’ll again get a bunch of verbose information followed by the listing of cmdlets.  Unfortunately, they don’t provide any real documentation yet, but you can see a listing of parameters using get-help.



    This is truly a case where we are getting early access to PowerShell functionality.  While not all of the functionality is ready yet, it’s great to see that we can get started.  Just being able to easily add members to a group using a PowerShell script already is a huge win!  Remember that these cmdlets are highly subject to change right now before you invest a lot of time building scripts around them.  I’ll update this post when the cmdlets are finalized.

    If you want to learn more about working with Groups, be sure and watch Ignite Session BRK3114 where they demonstrate some of these cmdlets in action.

  • Ignite Readiness Checklist

    I started doing SharePoint Conference readiness checklists back at SPC11 and I wanted to continue the tradition with Ignite.   This list may look similar to previous lists, but I have made lots of updates and additions.

    What to pack:

    • Chargers / Power Supplies – I remember when I went to PDC05, I forgot my laptop charger.  I was quite bummed.  Don’t forget the chargers to your laptop, netbook, Surface, phones, etc. I have gotten a few of these new emergency phone chargers at conferences lately and they are very handy here.  Especially when you have a Nokia Lumia 920 and the battery life is terrible.  Keep in mind your average day can be 16 – 18 hours plus and you don’t want to be left in the dark and miss that big gathering because your phone died.
    • Backup power – If any vendors are giving out backup power supplies, grab them!  You know the portable chargers that you can take with you.  We have several of them and they are a life saver.
    • Tablet / Laptop – You’ll want some kind of computer whether that’s a tablet, laptop, hybrid of whatever.  You want something with a keyboard.  This makes it easier to send e-mail or post tweets.  Besides, the more you are on this device, the less you have to rely on your phone and use its power. You also can use these to fill out session evaluations.  There are usually incentives for filling out evaluations so I try to complete each evaluation right before the end of the session so I don’t forget.
    • Bring your own Internet  – The wireless networks at conferences are rarely good.  They are jammed with geeks trying to post updates on Twitter and check out what’s happening on Facebook.  If you have access to a wireless AirCard, MiFi, tethring, etc, bring it.  See if your company has any that you can check out temporarily.  Conference organizers really don’t like you using these during keynotes because the more hotspots you create, the slower the Internet gets.  The slower the Internet gets, the more hotspots people turn on.  It’s a vicious cycle. I'd still bring your one if you can.
    • Cash – There are a lot of free events but you might go do something before or after the conference and I am not a fan of running tabs at busy restaurants and bars.   Don’t take it all with you every night.  Leave some in the hotel safe.
    • Snacks and Water – After a long night, you will want something to eat.  At the minimum, you might want something to eat in the morning.  The hotels will likely have stuff in your room, but it will cost you dearly.
    • Business Cards – Even if you are not in sales, bring twice as many as you think you will need.  You will go through them faster than you think.   It’s amazing how many people forget these at a conference.  Don’t be one of those people!
    • Bail Money – The Houston SharePoint Users Group has a running joke about always keeping a stash of bail money around when attending a #SharePint.  You never know what is going to happen.  0
    • Headset – If you think you are going to have to take any calls during the week, don’t forget your Bluetooth headset.  This will make it easier to do your calls for sure.
    • VPN Tokens - If your work network requires a VPN token or Smart Badge you might want to bring it if you think you might need to use it.  Otherwise, you might conveniently forget it, to ensure you can focus on the conference. :)

    Before you go:

    • Arrive early – Come in early and have some fun in Chicago before you get into the conference grind.  Many of us will be arriving Friday or Saturday.  I tend to arrive on Saturdays while most of the foreign nationals I know, tend to arrive Friday or earlier.
    • Don’t leave early – Normally I say this, but they have extended the conference by a day.  Come Friday, I’ll be ready to be on the first plane out of Chicago.
    • Set your schedule on MyIgnite - This will make your Ignite organizers happy when it comes to capacity planning.  You aren’t required to go to that session you schedule, but it will help you pick from the 10+ sessions going on at any given time slot.  Go to MyMignite and set your schedule now.   Not sure about a session, watch the teaser video on YouTube.
    • Create your Bio on MyIgnite  – Whether you are an end user or a rock star, take a few minutes to write about yourself.  Include where you work if you want along with what you typically do with the Microsoft stack and what you want to get out of the conference.  Upload a picture of yourself to make things more personal.  Be sure and set the privacy settings as desired.  Set your MyIgnite bio now.  Be sure and edit your profile on Yammer too.
    • Connect on MyIgnite - If you go to the Communities tab, you can search for other attendees. 
    • Get on Yammer - The conversations have already begun about Ignite on Yammer.  This is a great way to find out what other people are doing, network with others, and talk with people with similar issues.  Most importantly, you can have a conversation about the sessions while they are occurring.  Speakers will be watching Yammer before, during, and after their sessions.   Be sure and follow others in Yammer to have more show up in your social feed.
    • Create a #msignite Search in Twitter – Twitter hasn't gone away by any means, so keep an eye on the activity of the #msignite hash tag.  However, this year, I think Yammer is where you are going to find the most info and conversations.  Twitter will still be good to find out about sessions, events, and it will generally give you an idea of what is happening at the conference.  Be sure and include the #msignite hash tag on anything you post and help get this conference trending!
    • Follow @MS_Ignite on Twitter – @ms_ignite is the official twitter account for Ignite.  This account often posts useful stuff about the conference.  I’ve also used it to ask questions or provide general feedback and I’ve had very good luck getting a response.  Keep in mind this twitter account is effectively manned by one person, so if you have an inquiry, take it to Yammer.
    • Download the Ignite Mobile App – Whether you use iOS, Android, or you are one of the last few Windows Phone users, be sure and download the Microsoft Ignite App before you go.  Download it now while you still have good Internet!
    • Reach out to your local User Group – Find out what your local User Group is doing while at Ignite.  Many of them are having meetings or socials. 
    • RSVP for Parties – Unfortunately, if you haven’t RSVPed for parties by now, you’re probably out of luck.  However, being persistent can get you in.  Talk to the vendors in the exhibit halls hosting the parties.  Sometimes you can just show up and talk your way in.  Check the Events at Ignite Yammer group.  Also check Vlad’s Ultimate Party List regularly.  Be sure and follow @SPCPartyPatrol to find out where the parties are too!
    • Arrange for Ground Transportation  - Don’t forget to arrange for ground transportation.  You really don’t need a car in Vegas, but you do need a way to get there.  Taking a Taxi usually isn’t too expensive and there are plenty of shuttle options as well.  This may be less of a concern on arrival but more for your departure.
    • Leave space in your bag – Between the conference materials and the vendors you are going to end up with a heap of product information, trinkets, and T-shirts.  Make sure you have room in your bag to bring them home.  Otherwise you’ll be hand carrying them on the plane or leaving things behind.
    • Update your devices - Now is a great time to make sure your devices are up to date with the latest security patches.  Make sure they are charged too!
    • Set your out-of-office - You're at this conference for a variety of reasons, you need to focus.  Try to stay out of Outlook and let people know that you will be slow to respond.  If you need to stay connected, I recommend picking one time of day, such as in the morning before sessions, to catch-up on what's happening back at home.

    What to do at the conference:

    • What happens in Chicago, will not stay in Chicago – Nerds have gadgets and they like to take pictures.  Do something stupid and you can rest assure it will be on twitter within seconds. :)
    • Ask questions  - Don’t be afraid to walk up to the mic and ask a question.  That’s what you’re here for.  If you don’t want to ask it in front of everybody, wait in line and talk to the speaker at the podium just be mindful that the speaker has to clear out in a hurry.  Don’t be afraid to approach speakers outside the room either.  Most of them are friendly and are easily engaged using beer and cocktails. :)  It's not uncommon to find them at the official SharePint bar.
    • Make friends – You may run into lots of people you know, but many people aren’t active on twitter and aren’t familiar with the SharePoint community at all.  Find a friend if you didn’t come to the conference with any one.  It’s much more fun to go do all of the activities in a group rather than by yourself.  If you have coworkers there, feel free to hang out with them, but don't feel that you are obligated to.
    • Go to the evening events - I can't stress this enough.  Try to avoid team dinners that overlap with the events.  Get them rescheduled.  The evening events are where the real connections are made, friends are found, contracts are signed, and new jobs are discovered.  If you just go to the conference and nothing else, you are missing out on half the experience.
    • Remember to eat - This one sounds obvious but it’s not.  You may be going to lots of parties with nothing but light appetizers.  This does not give you a good base to work upon before embarking on a night of massive consumption. Pace yourself!
    • Don’t worry about writing everything down – Remember the slides and content will be on Yammer before the session.  Don’t stress out because you weren’t able to write down a URL or code snippet on a slide.   You can also take pictures of slides as well.
    • Visit the Exhibit Hall – The exhibit hall is a lot of fun.  Besides all of the SWAG and drawings, you are likely to find out about evening events that way. Make a point of going there every day.  I spend a good majority of my time there during the conference.  You'll never know who you run into.
    • Be on the lookout for the SharePoint Monkey – The word on the street is that the SharePoint Monkey will be making an appearance.  You'll never know what that silly monkey is going to be up to during the conference.  Be on the look out for him throughout the convention center.  Follow him on twitter @TheSPMonkey for clues!
    • Attend the sessions – Don’t skip out on the morning sessions.  If I have to get up early so do you. :)
    • Attend the Hands on Labs – If you haven’t had a chance to get your hands on the latest technology, get down to the HOL and check it out.  This is a great way to experience the product without having to take the time to install it.   It opens at 9:00 am on most days (after the keynote on Monday).
    • Take a test – Go roll the dice and find some time to take a test.
    • Don’t underestimate travel times – It’s a long bus ride to the convention center.  It can be between 15 and 30 minutes if not more.  Even within the convention center, there are long walks between sessions.  Plan accordingly.
    • Set your alarm before you go out for the night - Before you go out for the night, set your morning alarm on your phone.  You may not remember when you get back to your room.
    • Arrive early to sessions – Many sessions will fill up and entrance will be denied, especially futures sessions.  Don’t get left out by showing up late.
    • Don't be afraid to leave a session - If you decide in the middle of the session, that this one isn't for you, don't be afraid to quietly step out and go see something else.  A few speakers might call you out for it, but most won't. :)
    • Learn hash tags for the sessions you are attending – Every session you are attending has an associated hash tag that you can follow. 
    • Don’t wear your badge outside of the convention center – Nothing says you don’t have any game like walking out of the convention center with your badge on.  Take it off as you exit the area.  Don't lose it though as it may cost you a lot to replace it.
    • Don’t forget your badge (and lanyard) at the attendee party – You’ll need your badge everywhere you go.  Bring it and the lanyard. 
    • Keep your phone charged – The battery life on LTE phones is horrible and even worse when you are tweeting non-stop all day.  Keep an eye on your phone’s battery life and charge up throughout the day. 
    • Don’t be afraid to leave for lunch – I’m not a huge fan of conference food and it rarely gets along with my diet.  Usually by the second or third day I am grabbing anyone I can find and going off-site.  Find me at the conference and you can join me.
    • Fill out your evaluations – These really are important to the speakers.  Let them know they did a good job and take the time to leave actual text comments in them.
    • Establish rendez-vous points – Establish meeting spots in advance with your group and set a time to meet. 
    • Go to the attendee party – Go to the attendee party.  If you are expecting to meet people there, meet them before you leave the hotel.  If you don’t walk in with the people you want to see, you will likely not see them that night. 
    • Hydrate - Drink lots of water throughout the day.  This is especially important if you have had a lot of late nights.
    • Silence your phone during sessions, turn it on as loud as possible everywhere else - Don't be "that guy" who has your phone ringing in the middle of a session.  That's guaranteed embarrassment. When you're not in sessions, turn the volume up on it as you probably won't hear it go off otherwise when you get a message.

    That’s my list.  I’m sure there are other things to remember.  Do you have anything else to add?  Leave a comment.  This probably goes without saying, but if you are not on Yammer and Twitter, now is the time to join.  It’s the best way to keep up with what’s happening at the conference.

    I’m also presenting a session with Matt McDermott at this year’s conference and we would love for you to come see it.

    • #BRK4124Search Extensibility in SharePoint 2013 (Second Screen) (Thursday, May 7th, 5:00p) – Come on a tour of the common extensibility and development tasks needed to take advantage of the full power of SharePoint 2013 Search Service.

  • Display scaling improvements come with Windows 10 Build 10074!

    For those of you out there with a Surface Pro 3 connected to an external monitor, you know the pain of display scaling.  This typically caused a phenomenon where windows were sized normally on your Surface Pro 3 display while being massive on your external monitor.  Most users I have talked to found this absolutely frustrating.  The only real solution was to purchase an external monitor with an equally high DPI.  This meant purchasing a high dollar 4k monitor.  While those displays are nice, most people have plenty of good LCD displays in the 20” – 30” range which are working perfectly fine right now.

    With Build 10074 of Windows 10 Insider Preview, some of this pain goes away.  That’s because of the new ability to set the DPI scaling to an independent setting for each connected display in the new Settings app.  Now, I can set the display scaling to 150% on my Surface Pro 3 display but have my external monitors set to 100%.  Windows is smart and even auto detects the right settings for each. 

    Let’s take a look at this new setting.  The setting Chagne the size of text, apps, and other items is set to 150% (Recommended) on my Surface Pro 3 display.


    On my external monitor running a resolution of 1920x1080, the setting is set to 100%.


    This is great, but how does it perform?  I found that this fixed the issue in a lot of programs including some of the Office suite.  Let’s look at some examples.

    File Explorer on the Surface Pro 3 display:


    File explorer on an external display:


    Notice they are the same relative size!  You’ll actually see windows resize it as you move them as well.

    Word 2016 Preview does pretty well too.  Here it is on the Surface Pro 3 display:


    Word 2016 on the external display:


    File Upload dialogs used to be massive on external displays.  Now they are regular-sized.


    Some programs handled this better than others.  However, PowerPoint and Skype for Business (aka Lync) still have issues.  A typical chat still takes up more a large part of the screen.  Notice the difference in ribbon sizes between Word and PowerPoint.


    The new Microsoft Edge browser (still referred to as Project Spartan in this build) also has some issues as well.  For example, when you launch it on the Surface Pro 3 display, it will set the zoom level to 150%.  However, when you drag it to another monitor, it doesn’t adjust the zoom level automatically.

    There has also been some improvements in other Windows Universal apps so that they scale better on external monitors.  It isn’t perfect yet either but the snapping has definitely improved.

    Surface Pro 3 users have been crying out for improvements here and it’s nice to see that they are in the works.  I hope to see additional improvements as we see new builds.

  • Reading your skin temperature using the Microsoft Band SDK Preview

    Microsoft Band is packed with sensors that let it track your workouts.  However, one sensor you don’t hear about often is the Skin Temperature sensor.  This sensor allows you to read the temperature in Celsius of your skin where your Band is.  There aren’t any apps built-in to Microsoft Band that make use of it directly.  However, as a developer you can take readings from that sensor from an app on your phone using the Microsoft Band SDK Preview.  The SDK is very preliminary and you can only do a handful of functions from a phone including reading the sensors, creating tiles and sending notifications, and changing the theme and background image.  It has a direct dependency on the app you deploy to your phone.  You can’t actually build an app and deploy it so that it runs on Microsoft Band natively.  This limits you quite a bit, but you can still do a few cool things.

    For my example, I worked off the Sensors example project for Windows Phone 8.1 and made some customizations.  The app consist of a simple button that initiates our connection to the Band and starts taking readings.  You can customize the Sensors project as well or you can grab my copy from GitHub.  You can get the SDK from nuget by using the following command.  This will add the necessary project references.

    Install-Package Microsoft.Band -Pre

    Start by editing the XML of the Package.appxmanifest file and add the DeviceCapability section for Microsoft Band inside the Capabilities element.

    <DeviceCapability Name="bluetooth.rfcomm" xmlns="">

      <Device Id="any">

        <!-- Used by the Microsoft Band SDK Preview -->

        <Function Type="serviceId:A502CA9A-2BA5-413C-A4E0-13804E47B38F" />

        <!-- Used by the Microsoft Band SDK Preview -->

        <Function Type="serviceId:C742E1A2-6320-5ABC-9643-D206C677E580" />



    You also need to add the Proximity capability as well but you can do that through the UI.

    Now, we’ll work on adding some functionality to MainPage.xaml.  This consists mainly of a few TextBlocks and a Button.  Clicking the button will invoke our code to connect to Band and take a reading.  Create an event handling method for the button and mark it with async.  Now, we first need to get the paired Bands to the phone.  This assumes you have already paired your Band in the Bluetooth settings of the phone.

    // Get the list of Microsoft Bands paired to the phone.

    IBandInfo[] pairedBands = await BandClientManager.Instance.GetBandsAsync();

    if (pairedBands.Length < 1)


        this.textBlock.Text = "Band not paired.";



    To connect to Band we create an IBandClient in a using block.

    using (IBandClient bandClient = await BandClientManager.Instance.ConnectAsync(pairedBands[0]))



    Now we can read from the Skin Temperature sensor.  To do this, we bind an event handling method to the ReadingChanged event of the SkinTemperature class.  We’ll cover the event handling method just below.

    bandClient.SensorManager.SkinTemperature.ReadingChanged += SkinTemperature_ReadingChanged;

    Finally, we call StartReadingsAsync to start taking readings from Band.  We follow it with a delay of a minute before calling StopReadingsAsync to stop taking readings.

    await bandClient.SensorManager.SkinTemperature.StartReadingsAsync();

    await Task.Delay(TimeSpan.FromMinutes(1));

    await bandClient.SensorManager.SkinTemperature.StopReadingsAsync();

    In the event handling method, the value of e has a type of BandSensorReadingEventArgs<IBandSkinTemperatureReading>.  We can get the skin temperature in Celsius by using the SensorReading property.  For us Americans, we can convert that to Fahrenheit.  You know the formula right?  C * (9/5) + 32.  :).  Using the Dispatcher, we then write the value of the reading to the UI.

    private async void SkinTemperature_ReadingChanged(object sender, BandSensorReadingEventArgs<IBandSkinTemperatureReading> e)


        IBandSkinTemperatureReading temperatureReading = e.SensorReading;

        string text = string.Format("Temperature: {0}C", temperatureReading.Temperature);

        await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { this.textBlock.Text = text; }).AsTask(); 


    Now you are ready to run the program on your Windows Phone and see how hot you are!  Plug your Windows Phone into your PC via the USB port and then debug the program and be sure you choose Device in the options.  You can’t do this with the emulator.


    There you have it, my skin temperature was 30.69 Celsius (87.42 Fahrenheit).  Now you might be thinking now, “ok, neat, but how do I see that information on my Band”.  Well, you can push that information to your Band using a Tile.  In fact, I’ve included that code in my repo on GitHub.  However, you can only push information to your Band when the Windows Phone app is running.  That’s not all that useful.  I’ll cover tiles in a future post, but if you want to try it out for yourself, you can grab my code from GitHub.  I would have included it today but I found that adding tiles so far doesn’t always work as expected.  Maybe it will for you.

    This example really has zero practical value but I expect that we’ll see more opened up in the API in future versions.  If you have been interested in seeing what you can do with it as a developer, it’s worth checking out though.  For more examples of working with Band across platforms, be sure and check out the published documentation.

  • Creating an Azure Logic app that connects with SharePoint Online

    Logic apps are a great new feature in Microsoft Azure that lets you connect to a variety of systems and create triggers and events.  This allows you to reproduce some interesting light workflow functionality in an easy manner.  It comes with connectors for common Microsoft products like SharePoint Online, Yammer, and BizTalk.  However, it also includes connects to services like Twitter, SalesForce, SAP, and Dropbox.  It even includes a connector for on-premises SharePoint 2013 servers although it requires some additional configuration.

    As Logic apps are part of Azure, this is definitely a developer focused feature.  I don’t see end users working with these directly.

    Today, we’re going to look at expanding the Twitter / Dropbox example and expand that for use into SharePoint.  That example stopped at only inserting the first tweet into a file on Dropbox.  This example, will insert all tweets that have been returned from a user’s Mention timeline into a list on SharePoint Online. 

    First, I started by creating a simple custom list on my SharePoint Online (Office 365) site.  I am just using the Title column as well as a custom column named TwitterAccount to capture who sent the tweet.


    Like in the Twitter / Dropbox example, we need to create our connectors first.  We’ll create the Twitter Connector first. Start by logging into the new Azure portal at  Then click New, Developer Services, Azure Marketplace, API Apps.


    Select Twitter Service and then click Create.  Here you will be presented with some standard Azure settings that you will need to specify such as the App Service Plan, Resource Group, Subscription, and Location.


    Now, we need to repeat the process for the SharePoint Online connector.  Select the SharePoint Online connector out of the API Services list.  Here you need to also specify the URL to your site as well as the relative URL to the list.  For example, for my Tweets list I created, I specified a relative URL of Lists/Tweets.


    Now that we have created our connectors, we can get started with our Logic apps.  Create a new one by choosing Logic app under the API Services list.  If you can’t find any of these connectors or apps you can always just search for them.  After you click Create, you will be prompted for some settings.


    Give your app a name and then click Triggers and Actions to begin designing your app.  The canvas will appear and you can begin designing your app.


    To get started you simply click on the connectors you want to use.  The Twitter / Dropbox example starts with a recurrence connector to execute the task once an hour.  I didn’t want to accidently leave this app running so I checked the box Run this logic manually

    Now we’ll click on the Twitter connector to pull data out of Twitter.  The first time you do this you will be prompted for authentication by Twitter.  Once you login, it will show a list of common actions.  However, you can click the “…” to see more.


    In our case, we want to select Get Mentions Timeline.


    Now, we need to add our SharePoint Online Connector by clicking on it.  It will also prompt you for authentication as well.  It will then present you with common actions that you can preform on your list.  It will mention your list directly by name.  Choose Insert into <listname> to continue.


    We’ll be able to start mapping our data to the columns in the SharePoint list.  You can find the other fields by clicking on the “…” button.


    Don’t do the mapping yet though.  In the online example, it only inserted the first list item.  We’re going to implement repeating functionality to insert all of the list items.  Click on the cogwheel and choose Repeat over a list.


    You can also specify conditions from this menu but we’ll cover that in the future.  Now we want to specify the fields to use in our repeater.  In the Repeat Field click the … icon next to it and choose Get Mentions Timeline.  This will add the text @body(‘twitterconnector’) which is an internal syntax used by Logic apps.  Now we want to write the Tweet Text to the Title field and the Tweeted By field to the TwitterAccount field.  You can look at the options specified in the “…” menu but they don’t quite work right for repeaters.  You can start by picking This Action but we still have a bit of work to do.  It will add @repeatItem() to the box when you click it.


    Now we need to specify the field name.  We can actually infer this by looking at the Twitter Connector or by looking at the syntax it uses when we select a field from the “…” icon.  Since this is a preview release, the selectors for these fields don’t always give the same results.  Sometime if you select a field name it will do it correctly.  Other times it gives us the syntax that only returns the value from the first item returned.  Ultimately, I want to end up with a value of @repeatItem().TweetText for the Title field and a value of @repeatItem().Tweeted_By for the TwitterAccount field.  Here’s what the final settings look like.


    Click the checkbox to accept the values and then click Save at the top.  Finally you want to click Create to begin creation of your Logic app.  If you are going to make a lot of triggers and actions, I recommend you click Create first before you create them.  This will allow you save your progress as you work on things.  Nothing will be saved until you have created the Logic app itself first.

    Now are ready to manually run the Logic app manually.  Click the Run Now button at the top to begin.  You’ll see the progress in the Operations section at the bottom.


    Go back to the list on your SharePoint site to verify that the functionality worked.  You can see the list of tweets that mentioned me have been populated. 


    I noticed they didn’t necessarily come in the right order so it might be a good idea to bring in the date column as well.  When I made a schema change to my list earlier I had to recreate the SharePoint Online Connector for it to show up.  There might be a way to refresh it though.

    Logic Apps are an interesting technology with a lot of promise.  It makes some scenarios rather easy to implement in a short time.  I’ll continue to work with the technology to get a feel for what it can do and what the limitations are.  Try it out for yourself and see what you can do.

  • Troubleshooting errors with the client-side People Picker (SPClientPeoplePicker)

    I’ve done quite a bit of work with the client-side People Picker in SharePoint-hosted apps lately.  I find that while it is relatively easy to get set up, I found it was quite easy to break.  I have found that it tended to work better in Office 365 than it does in on-premises SharePoint 2013.  I ran into two common issues. First, I found that after you did a query for users, you could not actually select the user.  The second related issue is that you could select the user, but the textbox would remain empty and not show the user’s name.

    In my troubleshooting of the issue, I found that the behavior differed based on a variety of things including what user was using the page, how you authenticated, and which browser you were using.  When I was experiencing issues, I found that administrator users never had a problem.  That figures.  Low-privilege users would not be able to get the control to work.  Then I discovered that it would work for these users if they were not auto logged into the site with Internet Explorer.  Here, I am referring to the setting Automatic logon with current user name and password.  If the user typed in their credentials manually, it would actually work.  Quite strange.

    After further investigation, I discovered that access to the spMgr object deep in clientpeoplepicker.js was coming back as undefined.  This turns out to be in a block of code that shows presence information for the user.  I found that if I disabled presence, it fixed the issue for users in Internet Explorer.  To disable presence, set ShowUserPresence to false on the SPClientPeoplePicker object.  Do this right before your call to SPClientPeoplePicker_InitStandaloneControlWrapper.

    SPClientPeoplePicker.ShowUserPresence = false;

    This resolved my issues in Internet Explorer.  However, Chrome was displaying some erratic behavior.  Sometimes the People Picker would work, but most of the time it still wouldn’t.  Although this technique worked for some browsers, I don’t think it was the final solution.  I found the final solution also in the debugger.  I reported the following error in clienttemplates.js:

    Strings is not defined.

    The odd thing is that the minified version of strings.js was actually included on the page automatically but it didn’t work for some reason.  Strings.js is the JavaScript file that contains all of the multilingual string resources for your current culture.  I included a hard reference to the US English version of the strings.js file in the 1033 folder. 

    <script type="text/javascript" src="/_layouts/15/1033/strings.js"></script>

    Once I did that, all of my People Picker issues were resolved.  You may want to correct culture code for the languages you use.

  • Using Office Preview for Windows 10 with Office 365

    The new touch-friendly Office Preview apps for Windows 10 (aka Office Universal Apps for Windows 10) have native support for connecting to your personal OneDrive as well as Office 365.  When you first install the apps, they will take over your file associations.  When opening any of the desktop applications in Office 2013, you’ll see this right away as it prompts you to restore file associations.


    Since you can associate Office documents with the new Word Preview, Excel Preview, and PowerPoint Preview apps, that means we can use them to open documents in Office 365.  That means if you choose the option “Edit in PowerPoint” like in the example below, it will open with PowerPoint Preview.


    Windows 10 will open PowerPoint Preview for you and start opening the document from Office 365.


    Be warned, that opening documents from Office 365 takes a considerable amount of time.  This issue could be isolated to the tenant I was using though.


    If you haven’t added your Office 365 account to the Office Preview Apps for Windows 10 yet, you will be prompted for credentials when you first connect.


    Now you can edit your document as normal.  Remember, that the Save button is gone now and your changes will be updated automatically as you type.

    One thing I discovered in this process is that the apps do not support SharePoint 2007 (don’t ask me why I know).  I haven’t tried SharePoint 2010 yet, but I suspect it will work.  If you do try it, leave a comment and let us know how it went.

  • Office Universal Apps for Windows 10 - Who needs a Save button?

    Today, Microsoft released their Office Universal apps for Windows 10 Technical Preview.  That’s a long way of saying that touch-friendly Modern Applications (formerly known as Metro and Windows Store apps) finally exist for Windows tablets.  I’ve had the pleasure of using the apps throughout the day.  I wrote an entire technical specification in Word Preview today and things worked well.  However, the biggest change for me is the lack of the “Save” button.  It simply isn’t there. 


    For those of you familiar with Office Online (formerly known as Office Web Apps), this paradigm is nothing new.  Saves just happen auto-magically.


    I’ve found myself really having trouble adjusting to it.  I am used to typing a sentence or two and reaching for Ctrl+S to save my document.  That simply isn’t necessary any more.  Your changes will automatically be saved as you type.  Where you need to be careful is if you are editing a document directly from OneDrive and you are on a slow or latent connection.  Sometimes it takes a while for those updates to be pushed up to OneDrive.  This makes me fearful on what happens when you are offline or if you have network connectivity issues while you are working on a document.  This will require more testing on my part.

    Another aspect I find a little bit difficult for the consumer to master is when creating new files.  Whenever you create a new document in Word, it will automatically name the document Document (1).  It automatically creates this file in your default save location.  It will increment the document number if you have already created a document already too.  That means whenever you start a new document, it creates a physical file somewhere even before you save.  This is different than Office for the desktop where the copy is held in a temporary location until you hit save for the first time.  To choose a filename for the document, you either need to choose Save as or you can click on the filename at the top of the app.


    I guess this works, but it’s definitely different than what we are used to.  If you are going to try out these preview Office apps, be sure and proceed with caution.  The last thing you want to do is lose half a document just because of some pre-release issue.

  • A quick look at Universal Office Apps for Windows 10 (Touch)

    Since the release of Windows 8, we have all ben wondering when we would see a touch-optimized Office experience.  We saw apps delivered to both iOS and Android first, but still nothing for Windows other than Office 2013 for desktop.  All of that changes today as Microsoft has release previews of Word, Excel, and PowerPoint as Universal Apps for Windows 10.  If you are not familiar with the term Universal app yet, this is a single app that can run on Windows 10 desktops, tablets, and phones.  Support for Xbox One has even been pledged but there hasn’t been any updates on that in quite some time.  These look just like existing apps for Windows 8.1 formerly known as Metro, Windows Store, and now Modern Applications in Windows 10.

    You’ll need to be running the latest public build (9926) of Windows 10 to try these preview out.  The original blog post had links to Word, Excel, and PowerPoint.  However, they have been removed for the moment.  However, I still have the links to Word and Excel handy.  These links only worked for me in Internet Explorer.  If you try them on a Windows 8.1 computer, you won’t see the “Get” button nor will you be redirected to the Windows Store to download the app.  The blog posts says you can do a search from the new Windows Store (Beta) app, but I haven’t had it work yet.  This is typical though when a new app is released to the store.

    After you have installed the apps, launch them from your start menu or by asking Cortana.  We’ll start with Excel Preview.  Notice, Excel Preview listed as a Modern Application where Excel 2013 is a Desktop Application.


    When each Office Preview app starts, it will show you a quick three-step tutorial on how to get started specifically highlighting touch features.  Here, you learn how to move columns by touch.


    You can add rows and columns with a tap.


    Here, you have the option to join the customer experience improvement program.


    Once you start the app, you’ll see a familiar screen with templates that you can use to get started.  It will automatically pull in your recent files that you have used on OneDrive.


    Be sure and click on the Accounts button to add your Office 365 account if you have one.  Unfortunately, you have to do this in each app separately.


    You’ll then be able to see a list of all your apps across OneDrive for Personal and Business use like you see in this example from Word Preview


    If we create a new document, we’ll see a new touch friendly Excel.  The buttons and icons are spaced a part to make them each to touch with your finger.


    One feature I really like is the light bulb icon.  Clicking this will allow you to search for functionality that you can’t find in the ribbon.  For example, if I wanted to insert a chart, it gives me the options right there by typing the word “Chart”.


    Excel should be able to open many of your existing spreadsheets as well.  Although, I found that Excel Preview crashes quite a bit more than the other Office Preview apps.  Some of my spreadsheets it just refused to open.  That’s to be expected though.  Excel spreadsheets can get complicated quickly and this is a preview product.


    Some spreadsheets are out-right not supported.  If you are pulling data from a SharePoint list or using PowerView, it will display an error message telling you why.  I’m not surprised this doesn’t work but maybe it will some day in the future.


    For desktop users of Office 2013, the biggest change you will have to adjust to is that you can only have one file open at a time.  Now before you start bashing Universal apps on Windows 10, keep in mind that the Office apps on iOS and Android have this same restriction.

    I’ve been pretty excited to see the launch of Office for Windows 10.  We’ll cover Word Preview and PowerPoint Preview in an upcoming article.  While you may not use these apps on your Surface Pro 3 in desktop mode.   I think these apps will do great when the device is running in Tablet mode.  If you have been thinking about running Windows 10 on your device, be sure and check out my review on IT Unity.
