Question

postmessage发送按键消息应该填什么参数？

我百度查出来是这几个参数，但是编译器说VK_Z VK_Q VK_W VK_E 未定义，那参数应该是什么？
我要实现的是，当键盘按下Z时，程序广播按键 Q W E。正确参数是什么
error C2065: 'VK_Z' : undeclared identifier
error C2065: 'VK_Q' : undeclared identifier
error C2065: 'VK_W' : undeclared identifier
error C2065: 'VK_E' : undeclared identifier
下面是函数
LRESULT OnPress (HWND hWnd,UINT message,WPARAM wParam,LPARAM lParam)
{
if (wParam==VK_Z)
{
PostMessage (HWND_BROADCAST,WM_KEYDOWN, VK_Q, 0) ;
PostMessage (HWND_BROADCAST,KEYEVENTF_KEYUP, VK_Q, 0);

PostMessage (HWND_BROADCAST,WM_KEYDOWN, VK_W, 0) ;
PostMessage (HWND_BROADCAST,KEYEVENTF_KEYUP, VK_W, 0);

PostMessage (HWND_BROADCAST,WM_KEYDOWN, VK_E, 0) ;
PostMessage (HWND_BROADCAST,KEYEVENTF_KEYUP, VK_E, 0);
}
return TRUE;
}

A-Z的按键在windows里的定义并不是按照VK_A这样的规律的。

下面是各种键的定义，你自己参照下：
