模拟CTRL+V，但是没有释放CTRL，右边CTRL一直按下状态，求助！！！

[7teeth]

Sleep(200);
keybd_event(VK_CONTROL,MapVirtualKey(VK_CONTROL,0),KEYEVENTF_EXTENDEDKEY,0);//按Ctrl，不放开
Sleep(200);
keybd_event(VkKeyScan('V'),MapVirtualKey(VkKeyScan('V'),0),KEYEVENTF_EXTENDEDKEY,0);//V key;再按V键不放开
Sleep(200);
keybd_event(VkKeyScan('V'),MapVirtualKey(VkKeyScan('V'),0),KEYEVENTF_KEYUP,0);//放开V键
Sleep(200);
keybd_event(VK_CONTROL,MapVirtualKey(VK_CONTROL,0),KEYEVENTF_KEYUP,0);//放开Ctrl键

问题出在KEYEVENTF_EXTENDEDKEY这个参数上
不知道能不能解释下
这个参数和0有什么区别

::keybd_event(VK_LCONTROL, 0, 0, 0);
::keybd_event(0x56, 0, 0, 0);
::keybd_event(0x56, 0, KEYEVENTF_KEYUP, 0);
::keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);

释放ctrl用keybd_event(VK_CONTROL,mapvirtualkey(VK_CONTROL,0),KEYEVENTF_EXTENDEDKEY or KEYEVENTF_KEYUP,0);
