Code:

bool CheckForMine()
{
HWND Desktop = GetDesktopWindow();
HDC Hdc = GetDC(Desktop);
COLORREF Color = GetPixel(Hdc, 0, 0);
unsigned short int RED = GetRValue(Color);
std::cout << RED << "\t";
unsigned short int BLUE = GetBValue(Color);
std::cout << BLUE << "\t";
unsigned short int GREEN = GetGValue(Color);
std::cout << GREEN << "\n";
if (RED == 255 && BLUE == 255 && GREEN == 255)
return true;
return false;
}

[b]EDIT[/b]

Nevermind I got it to work, jsut switch GetDesktopWindow() to HWND_DESKTOP.

I used GetLastError(), but there was not errors. No matter what color I put in the top left corner, it iwll always return 255,255,255. What am I doing wrong?

EDIT

Nevermind I got it, all I ahd to do is change GetDesktopWindow() to HWND_DESKTOP.
