Good day guys! I am recently developing an attendance monitoring system using a webcam. I have successfully downloaded some sample programs how to make a webcam application in vb.net primarily using avicap. I tried to apply it on my program. The code seems fine but everytime i run the code, picturebox is unable to preview image from webcam. It turns black although it can save snapshot from the cam. I am using visual studio 2008 professional edition, windows 7 ultimate 32 bit. When i run it from windows xp, it previews the image from the webcam without any error. Hope u can give solution to my problems. I need it badly. thank you. Hope u reply.
