Hi,

I am wondering why does Getpixel always return 0 in fullscreen mode. I have no problems in windowed mode.

Thanks

When the game is in full-screen mode, the resolution changes.

I think it's 640 x 480, I guess your resolution is higher and you tried accessing a pixel that doesn't exist, 700, 500 for example.

Have you tried accessing a pixel like 1, 1?

perhaps the hdc is wrong
i'm pretty sure that in full-screen mode you should get the hdc to MS window and not get it with NULL value

I thought its 800x600 all the time regardless of window or fullscreen? anyways the pixel i tried getting is still within the range at 200, 250.

Thanks

Well, I'm not sure, but I think the window is recreated once you toggle, so try getting the HDC once again after you toggled.

i was just about to say GameGaurd hook GetPixel in userland with its dll it injects in to all process's

to bypass this hook you can use HookHopping which is all over this forum..
so i wont provide example code showing you how..

but if you need help in understanding the code i would be glad to help Smile
