如何用用程序模拟键盘来控制 MEDIA PLAYER 7，
例如 模拟CTRL+P来控制 MEDIA PLAYER 7的暂停可播放。
我用SENDMESSAGE函数可以模拟CTRL键控制其他程序（例如 WINAMP），却对MEDIA PLAYER 7不起作用。keybd_event函数效果一样。所以请大家帮忙，如果全能控制 MEDIA PLAYER 7可以重新开贴加分！谢了。

我说一下我的看法。象MediaPlayer这样支持换肤的程序，一般来说都应该处理WM_LBUTTONDOWN这样的消息，原因很简单，按纽都是自己画的，用CBitmapButton太麻烦了，并且效果很差。所以你只要给窗口发送这个消息就可以了，当然要设定要鼠标位置了，这样才有按钮的作用。

先谢谢楼上两位的热心帮助！
我用SPY++检测media player7所收到的消息，对于按下象CTRL+P这样的键，
media player7接受到的消息为
KEY_DOWN "VK_CONTROL" (POST)
KEY_DOWN "P" (POST)
KEY_UP "VK_CONTROL" (POST)
KEY_UP "P" (POST)
我用POSTMESSAGE函数模拟，SPY++也检测media player7收到了我发出的消息，但media player7就是不响应。
模拟鼠标也是一种办法，但鼠标不容易定位到支持换肤的media player7的‘按钮上。
请大家讨论！

告诉你一个很有效的办法：打开media player 和spy++，然后在media player按Ctrl+P，spy检测到WM_COMMAND的消息，其中wparam的低字节就是控件的ID。要模拟这一操作，只需要向media　player发一个WM_COMMAND的消息，其WPARAM 设置为刚才查看到的id号。

希望能对你有所帮助，转贴：
模拟键盘和鼠标输入
如果它不支持你需要的消息和方法，最简单的解决之道是键盘和鼠标输入模拟。例如，你可以使用Tab模拟转移到期望的控件。

使你做到这一点的函数是SendInput，它是一个一般的USER API。SendInput需要三个参数：要执行的键盘和鼠标动作的个数，INPUT结构数组，INPUT结构数组的大小。每个INPUT元素详细描述了一个要执行的动作。注意，按下一个按钮接着释放它是两个不同的动作，因此要建立两个INPUT元素。在例程中，SendInput函数用于模拟关闭Find: All Files 对话框的Alt-F4键盘序列：

INPUT input[4];

memset(input, 0, sizeof(input));



input[0].type = input[1].type = input[2].type =

input[3].type = INPUT_KEYBOARD;

input[0].ki.wVk = input[2].ki.wVk = VK_MENU;

input[1].ki.wVk = input[3].ki.wVk = VK_F4;

//接下来释放它，这一点很重要。

input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;

input[0].ki.time = input[1].ki.time =

input[2].ki.time = input[3].ki.time = GetTickCount();

SendInput(4, input, sizeof(INPUT));

在这个代码片断中，input[ ].type = INPUT_KEYBOARD表明要模拟键盘输入，input[ ].ki.dwFlags和input[ ].ki.wVk表明要执行的动作以及此动作的受键。特别要注意下面的语句：

input[2].ki.dwFlags = input[3].ki.dwFlags = KEYEVENTF_KEYUP;

没有这条语句，按下的键永远不会自动释放。

举例：

//模拟 alt + F
keybd_event(VK_MENU,0,KEYEVENTF_EXTENDEDKEY | 0,0);
keybd_event('F',0,KEYEVENTF_EXTENDEDKEY | 0,0);
keybd_event('F',0,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);
keybd_event(VK_MENU,0,KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,0);

已经结贴啦? 请问最后是如何解决的? 这样的特技用在什么场合啊?

我试了一下SendMessage怎么可以啊? 你的Media Player 7.0?

我的是8.0, OS = XP.

能告诉我你是如何获得Media Player的窗口的句柄的吗?

我用spy++看到的消息是WM_COMMAND, wParam = 00018028
lParam = 00000000

获得句柄后发消息即可:
if (found) {
MessageBox("found!");
::SendMessage( nextWnd->m_hWnd,
WM_COMMAND,
0X00018028, //WPARAM wParam,
0 //LPARAM lParam
);
};

这是个加速键,最后程序得到的是控件通知消息,

就这样,Media Player停止播放了.

keybd_event在win98和nt4以后被SendInput代替了，下面的例子将模拟按下‘s’键

INPUT keyInput;
keyInput.type = INPUT_KEYBOARD;
keyInput.ki.dwExtraInfo = 0;
keyInput.ki.dwFlags = 0;
keyInput.ki.time = 0;
keyInput.ki.wScan = 31;
keyInput.ki.wVk = 83;
UINT hr = SendInput(1,&keyInput,sizeof(INPUT));可以用归可以用，但是我们可以看一下msdn里面的建议：

Windows NT/2000 or later: This function has been superseded. Use SendInput instead.

如何模拟键盘输入特殊符号，如 （ % @ 等
SendMessage(Edit1.Handle,WM_CHAR,ord('%'),0);//向Edit1输入%
