I have this code on C++.. Someone here please translate it to au.
// init DC & bmps
HWND hWindow = GetDesktopWindow();
HDC DC = GetWindowDC(hWindow);
RECT Rect;
GetWindowRect(hWindow, &Rect);
int nWidth = Rect.Right;
int nHeight = Rect.Bottom;
HBITMAP hBmp = CreateCompatibleBitmap(DC, nWidth, nHeight);
HDC hMemDC = CreateCompatibleDC(DC);
SelectObject(hMemDC, hBmp);
BitBlt(hMemDC, 0, 0, nWidth, nHeight, DC, 0, 0, SRCCOPY);
COLORREF nColor = GetPixel(hMemDC, 200, 200)
