Getpixel and push button.
Hi. I'm trying to make a program that will push a virtual button if a certain pixel has a certain color.
The problem I got is that it only works sometimes. Is it because my function is too slow or why does this happend? Really annoying.
Check out my code:
using namespace std;
int _tmain(int argc, _TCHAR* argv)
BYTE redValue = 0;
HDC hDDC = GetDC( GetDesktopWindow() );
HDC hCDC = CreateCompatibleDC(hDDC);
HBITMAP hBitmap = CreateCompatibleBitmap(hDDC, 1600, 1200);
BitBlt(hCDC, 949, 794, 2, 2, hDDC, 949, 794, SRCCOPY|CAPTUREBLT);
