我想利用Wnd：：OnTimer函数来持续发送数据

我有四个按钮，分别持续发送不同的内容

我想问下我应该如何编写OnTimer函数啊。

void CGDesignDlg::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if(nIDEvent == IDC_MCODEUP_BUTTON)
{
OnMcodeupButton();
CDialog::OnTimer(nIDEvent);
}
else if(nIDEvent == IDC_MCODEDOWN_BUTTON)
{
OnMcodedownButton();
CDialog::OnTimer(nIDEvent);
}
else if(nIDEvent == IDC_MCODELEFT_BUTTON)
{
OnMcodeleftButton();
CDialog::OnTimer(nIDEvent);
}
else if(nIDEvent == IDC_MCODERIGHT_BUTTON)
{
OnMcoderightButton();
CDialog::OnTimer(nIDEvent);
}
else
{;}


我尝试了一下。这样写不行，寻求帮助。

OnTimer中查的不是ButtonµÄID£¬应该是TimerµÄID

enum TimerID
{
TimerIDUP = 1001,
TimerIDDOWN,
TimerIDLEFT,
TimerIDRIGTH,
};

在适当的地方Start ÕâЩTimer
StartTimer(TimerIDUP,1000, NULL);
StartTimer(TimerIDDOWN,1200, NULL);
StartTimer(TimerIDLEFT,1400, NULL);
StartTimer(TimerIDRIGHT,1600, NULL);

void CGDesignDlg::OnTimer(UINT nIDEvent)
{
switch(nIDEvent)
{
case TimerIDUP:
OnMcodeupButton();
break;
case TimerIDDOWN:
OnMcodedownButton();
break;
case TimerIDLEFT:
OnMcodeleftButton();
break;
case TimerIDRIGHT:
OnMcoderightButton();
break;
default:
break;
}
CDialog::OnTimer(nIDEvent);
}
