如何使用Win32截取当前屏幕截图？
How can I take a screenshot of the current screen using Win32?
推荐答案
// get the device context of the screen
HDC hScreenDC = CreateDC("DISPLAY", NULL, NULL, NULL);
// and a device context to put it in
HDC hMemoryDC = CreateCompatibleDC(hScreenDC);
int width = GetDeviceCaps(hScreenDC, HORZRES);
int height = GetDeviceCaps(hScreenDC, VERTRES);
// maybe worth checking these are positive values
HBITMAP hBitmap = CreateCompatibleBitmap(hScreenDC, width, height);
// get a new bitmap
HBITMAP hOldBitmap = SelectObject(hMemoryDC, hBitmap);
BitBlt(hMemoryDC, 0, 0, width, height, hScreenDC, 0, 0, SRCCOPY);
hBitmap = SelectObject(hMemoryDC, hOldBitmap);
// clean up
DeleteDC(hMemoryDC);
DeleteDC(hScreenDC);
// now your image is held in hBitmap. You can save it or do whatever with it
