    <p>I'm working on the Kinect, and sporadically the Kinect makes Visual Studio Crash.</p> <p>It's happening when I call the <code>kinectSensor.Start()</code> method after debugging I found out that the <strong><em>Kinect is already in use in another process</em></strong>.</p> <p><strong>But no other processes is using the Kinect!</strong> It happened one time on the morning after booting my machine and launching the app. But most of the time it occurs when I launch the Kinect App (in debugging mode in VisualStudio 2010), I stop the application and after some code modification I re-launch the app and that time it doesn't work, I've got the above exception and after 2sec Visual Studio crashes.</p> <p>Moreover I check if the Kinect is already running and this is not the case (below the state of the Kinect sensor during debugging):</p> <p><img src="https://i.stack.imgur.com/rNGu1.png" alt="state of kinect sensor (debug mode)"></p> <p>The weirdest thing above all is that sometimes it works fine for weeks, and after that it makes that thing for two days every two/three launches of the app.</p> <p>The only solution I found on the subject is from one guy with a very similar problem (the only one on the internet?) : <a href="http://imadelayyan.com/?p=8" rel="nofollow noreferrer">Imad Elayyan</a></p> <p>When I launch <a href="http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx" rel="nofollow noreferrer">Process Explorer</a> I found the exact same problem of USB port handling (shown on the photo), a mutant process which is not terminated when we close the app.</p> <p><img src="https://i.stack.imgur.com/xjMHq.png" alt="mutant process for the USB handle of the Kinect"></p> <p>But his solution is <em>not really</em> a long term solution: I have to kill manually the mutant and re-start VisualStudio. Sometimes I have to restart VS 20 times on the morning...</p> <p><strong><em>Is there a way to properly close that handle of the usb port (in code?) so that when I close the app it terminate that handle and doesn't makes VS crash anymore?</em></strong></p> <p>Any help would be appreciated, it is really puzzling me and it drives me crazy.</p> <p><strong>Additional information</strong>: </p> <p>i'm using the <em>SDK1.5 + Kinect for Windows</em> but it was also the case with the <em>SDK1.0 + Kinect XBox360</em></p> <p>I've already try to debug VS with another instance of VS.</p>

    1. COThis sounds like an SDK bug, or something the SDK team should address at least. Can you report this to the project team somehow? Unfortunately I don't see it on https://connect.microsoft.com/

    2. COI didn't find how to contact them either. I tried your link and the official Kinect for windows website (developer => Get technical support), but I'm redirected to XBox live and then I 'm unable to find how to address my problem. I'll search again...

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
