捕捉键盘输入的简单办法
sardis 发表于 2007-06-02 22:17:27
比较有效的键盘输入捕捉方法为使用hook函数，然后这种方法比较复杂，今天在网上早到一种新的简单的捕捉方法。
即可以在PreTranslateMessage(MSG* pMsg)中进行处理：
如：
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->message == WM_KEYDOWN) {
switch(pMsg->wParam) {
case VK_LEFT:
*Command=0x01;
SendSocket.SendTo(Command,1,LINKPORT,videoconfig.m_ipaddress);
break;
case VK_RIGHT:
*Command=0x02;
SendSocket.SendTo(Command,1,LINKPORT,videoconfig.m_ipaddress);
break;
case VK_DOWN:
*Command=0x04;
SendSocket.SendTo(Command,1,LINKPORT,videoconfig.m_ipaddress);
break;
case VK_UP:
*Command=0x03;
SendSocket.SendTo(Command,1,LINKPORT,videoconfig.m_ipaddress);
break;
case VK_SPACE:
*Command=0x05;
SendSocket.SendTo(Command,1,LINKPORT,videoconfig.m_ipaddress);
}
return TRUE;
}
