Hi!!

I know that each pixel as 5 channels RGBAw (Red, Green, Blue, Alpha, w i dont know what means). How can i get these Channel Information outside my form for a individual pixel. I mean in the desktop etc. I know that windows allows multiple windows to be at the same point. And manages which one "gets on the top". How can i get the "order" of them and the channels information for a individual pixel?

Thks a lot in advance.
