>>Does it report a different device name and id each time?
Yes, it reports ids:
Code:
{...}\000;
{....}\007(I don't know why it is 007, probably according to the USB port. By the way, I have 8 USB ports on my computer);
{....}\002
Also, I can see the lights on the the three receivers flashed from red to green. So I am sure it functions from different channel.
Oh, I got a tricky problem now. When last time channel 1 cam is used in the webcam own software, the picture will be taken differently at the first two pictures. However, when last time channel 2 or 3 is used, the three pictures will be the same.
>>You could try a DoEvents/Sleep in the loop.
How can I write such a loop? Could you give me details?
Also, try calling CommonDialog1.ShowSelectDevice to make sure each camera is supported.
>>I'd suggest breaking it up a bit and looking around.
I will try your code.
Thank you so much
