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
