Webcam Screenshot

Hi,

I'm currently developing a program which captures image from a webcam. I have searched through the PAQs and found AmigoJack's sample code. All is well except that the captured image (i.e. webcam.jpg) renders black screen. It doesn't capture the content of the panel. Can someone guide me how to fix it? Thanks.

I actually tested both but all I get is a blank black image. Tested it using my desktop but this time a blank white image was produced. If it works for you then the problem could be the virtual cam that I'm using. I'll try plugging a real webcam tomorrow and let you know if it works.

if you have time, can you also test using a virtual cam? I'm currently using this

Let me know if the problem is the same.

Thanks.

I tried plugging a real webcam (logitech quickcam pro 4000) but I can't still get the captured image. what makes it strange is that when I test it on my desktop at home, the produced image is plain white while using my laptop at work produces plain black image. i'm using delphi 7. what version and webcam did you use? thanks.

I managed to solve this problem using DSPACK. For those who will encounter the same problem, try looking for the VMRSnapshot and videocap demos.

Even though I am awarding the points to mokule for his effort in helping me.
