    <p>I have a video capture (usb-webcam) application that currently uses very old VFW with p-Invoke hookup to C#. I'm trying to replace it and I stumbled on the <a href="http://muonics.net/school/spring05/videoInput/" rel="nofollow">VideoInput library</a>, and later found <a href="http://code.google.com/p/videoinputsharp/" rel="nofollow">VideoInputSharp</a>. I managed to get <a href="http://code.google.com/p/videoinputsharp/" rel="nofollow">VideoInputSharp</a> into my application and it gives me the frame rate and camera control I need. The problem is that on some PCs the call to VideoInput.IsFrameNew() never returns true even though the device is set up (VideoInput.IsDeviceSetup() does return true). I've successfully run this on a W7x64 system and a XPx32 system, but does not work on W7x32. Any thoughts on why this is happening?</p> <p><strong>UPDATE1:</strong> Since originally posting this question, I've found that on the systems that don't work, I am still able to call VI.ShowSettingsWindow() to generate a dialog box; however, it is a different dialog box than I see on the systems that work (even though it is the same camera/driver). Is this a clue? Also note that I'm running the same version of DirectX on the machine it works with and the machine it doesn't work with.</p> <p><strong>UPDATE2:</strong> The systems that this is failing on are W7x32 and W7x64 both using a Microsoft LifeCam. I found yesterday that if I remove the Microsoft LifeCam software from the machine it then works! I sure could use an explanation for that.</p>

    2. CONot totally sure I understand your question. I'm working with a webcam, and the drivers are installed; and although the webcam can vary, in this case the same webcam is being used on the systems it works on and the systems it doesn't work on.

    3. COI see. You just didn't state that in the question, that's why I ask. And does the camera work on every system in some other applications?

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.
