    What windows UI dialog? Is it present in the SelCapDrvDlg in this application? Set a breakpoint in main.cpp line 199. What are the indexes of the 2 webcams you are interested in?

        And there we have it. One of your webcams only has a WDM driver. You would have to write a DirectShow application.

            If you have VC7+, download and install the latest Platform SDK. Go to http://tmhare.mvps.org/downloads.htm[^] to get the project files for the samples since Microsoft has for some reason stripped it out. Then go have a look at the PlayCap sample application in "..\Program Files\Microsoft Platform SDK\Samples\Multimedia\DirectShow\Capture\PlayCap" If you have VC6 though, you would have to grab an old DirectX SDK, maybe 2003 or 2004.

                    Your copy of Visual Studio .NET doesn't come with the C++ compiler? I never used CBuilder before so I guess you're on your own in building/getting compatible libs. Here's a link to get you started. http://www.geocities.com/foetsch/borlibs/[^] http://clootie.narod.ru/cbuilder/index.html[^]
