PixelGetColor always returns black

[SaphuA]

I thought I could have a little fun this morning trying to write a simple fishing bot for Fate: Undiscovered realms... guess again!

When I use PixelGetColor I always get a black pixel returned. I also tried to use _ScreenCapture_CaptureWnd, but that aswell returns a full black image.

What could be causing this? And how to fix it?

Ps. I am using a dual monitor setup, does that have something to do with it?

Edit: This does the same aswell: http://www.autoitscript.com/forum/index.php?showtopic=63318

Edit: I also noticed Windows Vista is not able to create a preview when I hover over the item

Some games are protected from these types of functions, and its not always intentional. It's just the way the screen is drawn.

But is there no way I could get it from the memory or something? I mean, eventualy the pixel data gets drawn to screen it has to be somewhere.

One other thing I'm wondering about though; how come that windows print screen does work? Is there no way to read the data the way windows does?

Or... what would be the fastest way to save/paste the windows screenshot and read data from that?
