I found on Google Someone wrote a function similar to PixelGetColor But it also works on a minimized window .. #include <iostream> #define _WIN32_WINNT 0x0501 #include #define PixelGetColor(x, y) PixelGet(mDC, x, y) int CreateContext(char *window_name, HDC *hDC, HDC *mDC, HBITMAP *hBM) { RECT win_stats; HWND hwnd = FindWindow(NULL, window_name); if(!GetClientRect(hwnd, &win_stats)) { return 1; } *hDC = GetDC(hwnd); *mDC = CreateCompatibleDC(*hDC); *hBM = CreateCompatibleBitma
