<br>内容：CTime里有GetYear(),GetMonth(),GetDay(),GetHour(),GetMinute()<BR>等函数，你利用这些就可以很容易判断啊

<br>内容：可用下面m_Time 和昨天时间进行比较既可。<BR><BR>如下：<BR>CTime nowtime = CTime::GetCurrentTime();<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_sNowTime = nowtime.Format(_T("%Y-%m-%d %H:%M:%S"));<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;m_Time = CTime(nowtime.GetYear(),nowtime.GetMonth(),nowtime.GetDay(),nowtime.GetHour(),nowtime.GetMinute(),nowtime.GetSecond());<BR>

<br>内容：用下面类似方法判断时间：<BR><BR> int hour,min,sec;<BR>&nbsp;&nbsp;int yhour,ymin,ysec;<BR>&nbsp;&nbsp;&nbsp;&nbsp;<BR>&nbsp;&nbsp;&nbsp;&nbsp;CTime nowtime = CTime::GetCurrentTime();<BR>&nbsp;&nbsp;&nbsp;&nbsp;m_sNowTime = nowtime.Format(_T("%Y-%m-%d %H:%M:%S"));<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;UpdateData(FALSE);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;if(bSetTime)<BR>&nbsp;&nbsp;&nbsp;&nbsp;{<BR>&nbsp;&nbsp;&nbsp;&nbsp;hour = nowtime.GetHour();<BR>&nbsp;&nbsp;&nbsp;&nbsp;min&nbsp;&nbsp;&nbsp;&nbsp; = nowtime.GetMinute();<BR>&nbsp;&nbsp;&nbsp;&nbsp;sec&nbsp;&nbsp;= nowtime.GetSecond();<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;yhour = m_Time.GetHour();&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //旧时间<BR>&nbsp;&nbsp;&nbsp;&nbsp;ymin&nbsp;&nbsp;= m_Time.GetMinute();<BR>&nbsp;&nbsp;&nbsp;&nbsp;ysec&nbsp;&nbsp;= m_Time.GetSecond();<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;//如果时间到，则关机<BR>&nbsp;&nbsp;&nbsp;&nbsp;if(hour == yhour && min == ymin )<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WinShutdown(EWX_SHUTDOWN);<BR>&nbsp;&nbsp;&nbsp;&nbsp;}<BR><BR>
