发送Keydown消息，可忘了怎么带Ctrl(100分)

发送WM_KEYDOWN,只记得发送Key,忘了怎么发送Ctrl,Alt信息<br>书不在身边，哪位能告诉一下？

(ssctrl in shift)

SendMessage(handle,wm_keydown,vk_control,0);//發送Ctrl信息<br>SendMessage(handle,wm_keydown,vk_menu,0);//發送Alt信息

我要发送Ctrl+Home Ctrl+end等KeyDown ，Windows编程书都有，只是我现在没书，又出不去

我印象中Ctrl是否按下是和VK_HOME一起在lParam中体现的，Ctrl,Alt等是根据lParam的某位是否<br>为1来设置或判断是否按了Ctrl或Alt,哪位帮我查下书，介绍Windows消息的书上好象都有的

你可以：<br>&nbsp;MapVirtualKey(VK_CONTROL,1);<br>&nbsp;sendmessage(Handle,wm_keydown,VK_HOME,0);<br>達到同時發送Ctrl+Home的目的。

以上几位的都没试过吧？<br>不过我自己已经解决了，但却发现只有RichEdit有输入焦点时才能接受Ctrl+home,而PageDown<br>却不需要任何条件，可能是Windows自己的原因了，

还有没有别的方法？

可以用KEYBD_EVENT来模拟键盘操作

&nbsp;keybd_event( VK_MENU, MapVirtualKey( VK_MENU, 0 ), 0 , 0 ); &nbsp; &nbsp; // Alt down <br>&nbsp; keybd_event( VK_DOWN, MapVirtualKey( VK_DOWN, 0 ), 0 , 0 ); &nbsp; &nbsp; // down arrow key down <br>&nbsp; keybd_event( VK_DOWN, MapVirtualKey( VK_DOWN, 0 ), KEYEVENTF_KEYUP , 0 ); &nbsp;// down arrow key up <br>&nbsp; keybd_event( VK_MENU, MapVirtualKey( VK_MENU, 0 ), KEYEVENTF_KEYUP , 0 ); &nbsp;// Alt key up <br><br>另加补充：<br>Ctrl: VK_CONTROL<br>SHIFT:VK_SHIFT<br>TAB: &nbsp;VK_TAB<br>'A': &nbsp;byte('A') &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br>

获得了其他程序一个窗口的句柄，如何模拟按键ALT－R发送给它啊？<br>

Alt好像没法发。。。。

说错了，Alt的虚拟键值是VK_Menu，因此要模拟一次Alt按键的话可以：<br>keybd_event(VK_Menu, 0, 0, 0); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // 按下<br>keybd_event(VK_Menu, 0, KEYEVENTF_KEYUP, 0); &nbsp; // 松开
