同时执行两个SetTimer的问题

求高手指教 我做了模拟器  下面是关于计时器的一部分代码但是在执行时，相应的却都是按照时间间隔短的那个计时器来的  请问应该怎么解决void CsimulatorsDlg::OnBnClickedRotate()           //正转按钮
{
// TODO: 在此添加控件通知处理程序代码
CString temp1;
m_zhengzhuan.GetWindowText(temp1);
if (temp1=="正转")
{
m_zhengzhuan.SetWindowText("停止");
SetTimer(3,1500,NULL);
SetTimer(2,8,NULL);
}
if (temp1=="停止")
{
m_zhengzhuan.SetWindowText("正转");
KillTimer(2);
KillTimer(3);
}

}
void CsimulatorsDlg::OnTimer(UINT_PTR nIDEvent)
{


//CDialog::OnTimer(nIDEvent);
switch (nIDEvent)
{
case 1:
{
int dangqian,mudi;
CString lastfuck;
m_cur_floor.GetWindowText(lastfuck);
dangqian=atoi(lastfuck);
mudi=atoi(xtshi);
if (dangqian<mudi)
{
dangqian=dangqian+1;
lastfuck.Format("%d",dangqian);
m_cur_floor.SetWindowText(lastfuck);
::WritePrivateProfileString("CURRENT FLOOR","current_floor",lastfuck,url_config);
::WritePrivateProfileString("CURRENT FLOOR","destina_floor",xtshi,url_config);
}
