Simulate keyboard:

       // Simulate key down: ALT+PRINTSCREEN
       keybd_event(VK_MENU, 0x45, KEYEVENTF_EXTENDEDKEY, 0);
       keybd_event(VK_SNAPSHOT, 0x45, KEYEVENTF_EXTENDEDKEY, 0);
       // Simulate key release
       keybd_event( VK_SNAPSHOT, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
       keybd_event(VK_MENU, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
