您需要创建BITMAP并在您的DC中选择它：
RECT rt; GetClientRect(hWnd, &rt); HDC myHdc = CreateCompatibleDC(hdc); CBitmap bitmap = CreateCompatibleBitmap(hdc, width, height); HBITMAP oldBitmap = ::SelectObject(myHdc, bitmap); DrawText(myHdc, szHello, strlen(szHello), &rt, DT_CENTER); BitBlt(hdc,0,0,rt.right-rt.left,rt.bottom-rt.top,myHdc,0,0,SRCCOPY); ::SelectObject(myHdc, oldBitmap); EndPaint(hWnd, &ps);
