Hey experts

I am making a program that monitors a screen on another computer on the network.

I need to see which pixels have changed and send it back. But i dont want to use a timer or anything of that sort to check the screen every second or so because it takes up alot of resources.
I am looking an ez solution to this problem
So i would like to know if it is possible to let my program to receive a message when a pixel has changed on the screen.

Thank You,
Anar

You need to hook some Windows messages.
Look at VNC source code how to do that.
