I need to program a Video Card. I want to take images and save it to disk by my own. I have a Zoltrix card. Is there any standard way to program it? I will give 300 points for source code in Delphi.

I can't understand why you can't use windows drivers. Working with Widows Api Functions is good. I think so you can't do this better.
Ernesto,

Mirek is riight. Unless your into self-torture stick with the Windows API functions. If that's still not low-level enough for ya then contact Zoltrix and get them to send you the details on thier device drivers. If even that is not deep enough, contact the chip manufacturer for the I/O routines for the chipset on the video card (Hope you know assembly language!). Any way you cut it, if you go beyond the Windows API you are going to have your hands full.

My advice? Study the DirectX drivers (Microsoft) and work with the routines they provide. Should handle everything your looking to do with EASE :)

Good luck with your project!

If your video card support VFW (Video for windows), which he must support. You can download components that show the video on your screen, Save it to AVI, or capture it whenever you want it to.
You'll find those components in this address:
