C++ programming and VFW interface help needed

[patrickm]

as part of a robotics project i've been working on, i'm doing some realtime (maybe 15fps realtime) image processing to do object targeting. anyway, my problem is how to get the frames from the card to my program. i've heard once you send the required parameters to the card, you get back an array that is the frame. anyhow, my question is:

what needs to be included to access the VfW functions i'll need for a frame grab?
what arguments do you pass to the card, and how?

i'm using MS visual C++ 6.0. i think this should be a pretty basic operation, but i don't know where to look.

thanks

This is a little over my head but here are a few links that might point you in the right direction:

get the MS DirectX SDK. Under DirectShow are some samples for VideoCap including source.They might help.
