Capture photo from webcam

Question

Hi all I have a problem with capturing photos from two identical webcam(same vendor same camera). Since the two webcams using the same driver I can only reach one webcam at one time. The samples that I ve been looking at are small project done by using avicap.dll and even if I use different types of cameras I can not reach both of them at one time. It seems like the API selects one webcam and uses it. What do you recommend to capture photo from two webcams especially from two identical webcams? I'd be glad if you help me with that

Hi again Bechir Bejaoui I have tried the code you suggested in http://www.c-sharpcorner.com/UploadFile/yougerthen/810262008070218AM/8.aspx page and it really helped me. Thank you so much. But I want to ask one last question. With little bit searching on the net I found some code and I can get the GUID of the webcam attached to the computer. I have three webcams attaced to my computer and for example one of the GUID is @device:pnp:\?\usb#vid_05a9&pid_4519#5&1fa5549f&0&4#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global and I need to place this GUID somewhere in your code. But I cant really figure where to do so. I think I should point this GUID to the SendMessage function: SendMessage(hHwnd WM_CAP_DRIVER_CONNECT DeviceID 0) but where? Because this is the place where Windows wants me to select the webcam manually. Since I can get the GUID of webcam I dont want to select it but to be selected by the program automatically.But how? Any advice? Thanks again

you can hide this dialog box and connect directly to you device if it is detected by the system of corse all what you need is a little rectification of the code

HiBechir Bejaoui Thanks for the response. But what I need is that the user must select the webcam device from the program not via seperate window or select device dialog. I want to integrate webcam selection into the program. Therefor I need a list of webcams attached and connect the webcam device to a picturebox or something. Thanks
