MFC 模拟真实按键

Question

keybd_event(VK_CONTROL,0,0,0);
keybd_event('C',0,0,0);
keybd_event('C',0,KEYEVENTF_KEYUP,0);
keybd_event(VK_CONTROL,0,KEYEVENTF_KEYUP,0); ok , 可以模拟 CTRL+C

Answer 1

亲，每个Keybd_event需要延时的keybd_event(17, 0, 0, 0);Sleep(50); keybd_event(86, 0, 0, 0);Sleep(50); keybd_event(86, 0, 0x2, 0);Sleep(50); keybd_event(17, 0, 0x2, 0);你可以拿个播放器测试一下空格键.

Answer 2

嗯,sendkey就能实现发送CTRL + C等功能
