为何不能模拟按键? ( 积分: 30 )

我想用一下代码模拟按下ALT+S组合键,不过没有作用,在用QQ测试时发现并没有成功模拟按下ALT+S组合键,倒是把字母&quot;S&quot;输入到对话框中去了<br>keybd_event(MOD_ALT, MapVirtualKey(MOD_ALT, 0), 0, 0);<br>keybd_event(Ord('S'), MapVirtualKey(Ord('S'), 0), 0, 0);<br>keybd_event(Ord('S'), MapVirtualKey(Ord('S'), 0), KEYEVENTF_KEYUP, 0);<br>keybd_event(MOD_ALT, MapVirtualKey(MOD_ALT, 0), KEYEVENTF_KEYUP, 0);<br>不过,用以下却可以模拟Ctrl+Enter组合键,这是为何?<br>keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), 0, 0);<br>keybd_event(Ord('V'), MapVirtualKey(Ord('V'), 0), 0, 0);<br>keybd_event(Ord('V'), MapVirtualKey(Ord('V'), 0), KEYEVENTF_KEYUP, 0);<br>keybd_event(VK_CONTROL, MapVirtualKey(VK_CONTROL, 0), KEYEVENTF_KEYUP, 0);

keybd_event(VK_MENU, 0, 0, 0);<br>keybd_event(Ord('S'), 0, 0, 0);<br>keybd_event(Ord('S'), 0, KEYEVENTF_KEYUP, 0);<br>keybd_event(VK_MENU,0, KEYEVENTF_KEYUP, 0);<br>应该就行了<br>

同意楼上 &nbsp;但为啥ALT在VK里是VK_MENU啊

大概微软觉着ALT键总是用来调出菜单吧^_^

接受答案了.
