Hello all,
I found the following visual basic 6.0 source code on the web for
displaying web cam video in a GUI. However, I want to display video
from a camera which is hooked up through firewire (IEEE 1394), not
USB. What portion of the code would I need to change in order to
achieve this?
Thanks in advance,
-Bill
