What I want to do is get my screen into a pixel array(array or rgb structs).
I got a program running that loads a .bmp and does this but I want to skip the manual printscreen and loading and get it straight into an array.
I searched a lot for this but I couldn't find anything this specific.

hWnd [in]
A handle to the window whose DC is to be retrieved. If this value is NULL, GetDC retrieves the DC for the entire screen.

That was amazingly simple. Thanks.
For anyone searching on google here's all you need to process the pixels on your screen:
COLORREF pixel = GetPixel( GetDC( NULL ), x, y );
cout<< (int)GetRValue( pixel );
//GetDC(NULL) is the full screen and x, y are the coordinates
//GetRValue(pixel) gets the red value of the pixel as a byteGetDC() will return a device context from within its context. So within a CDialog class the method will return a CDC pointer that can be used to paint to the CDialog.
