I'm trying to grab video from an external webcam/industrial vision camera and display it (and later I'd like to capture frames for making a photo-mosaic). I'm automating a microscope in our lab to capture video, drive the motorized stage, and capture Raman spectra. The camera and spectrograph have really clunky interfaces in Matlab, but the C interfaces are well developed.</p> <p>I'll be working with a single type of camera (Thorlabs DCC1645C), so I'm not sure that I need to display the camera list, just search through and select the one of interest. I'm not familiar with the built-in classes for capturing and displaying video in windows using c++ or c#, but I have handled streaming video in Matlab in the past. Could you give me a starting point for where to look?</p> <p>Thanks,</p> <p>Francis</p> re: C# WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9849753Mon, 27 Jul 2009 10:08:29 GMT91d46819-8472-40ad-a661-2c78acb4018c:9849753arm2n@hotmail.com<p>Okay than you... i can't follow you ... cry 22222</p> <p>please teach me for </p> <p>create video conference with c# .Net</p> <p>and if have camera component for web application</p> <p>it's so very thank you ....</p> <p>(i'm thai peaple)  best regard .... :)</p> re: C# WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9871416Sun, 16 Aug 2009 09:58:46 GMT91d46819-8472-40ad-a661-2c78acb4018c:9871416Jalil Abdollahi<p>I have Problems !!!!</p> <p>Why I cannot access and take pictures from a method call from another class? </p> <p>I cannot take pictures if the picture box is hidden !!!</p> <p>tell me what to do... pleaaaseeee</p> re: jsp WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9876905Thu, 20 Aug 2009 15:20:46 GMT91d46819-8472-40ad-a661-2c78acb4018c:9876905giri<p>hi please i need to capture the picture in jsp page through webcam,</p> <p>please please any one can help by sending the code to</p> <p>kgirish10@gmail.com</p> <p>thanks in advance</p> re: C# WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9897373Mon, 21 Sep 2009 06:44:49 GMT91d46819-8472-40ad-a661-2c78acb4018c:9897373Zach<p>When I tried o make the gadget I cant find this WebCamControl2.dll</p> re: C# WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9902785Sat, 03 Oct 2009 20:39:56 GMT91d46819-8472-40ad-a661-2c78acb4018c:9902785Jesse Chunn<p>I would like to see an example of enumerating capture devices.</p> re: C# WebCam User Control Sourcehttp://blogs.msdn.com/markhsch/archive/2007/11/19/c-webcam-user-control-source.aspx#9906999Wed, 14 Oct 2009 06:00:21 GMT91d46819-8472-40ad-a661-2c78acb4018c:9906999jay<p>How can i play video from the composite video input of a tv card?</p>
