code:
keybd_event(VK_CONTROL, 0, 0, NULL);
keybd_event(0x41, 0, 0, NULL);
keybd_event(0x41, 0, KEYEVENTF_KEYUP, NULL);
keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP, NULL);
keybd_event(VK_DELETE, 0, 0, NULL);
keybd_event(VK_DELETE, 0, KEYEVENTF_KEYUP, NULL);
will beep if there's nothing to delete i.e. when the Input area is empty. Any way to stop it beeping?
