定时关机，用srvany安装成服务使用。

示例代码工程，基于vs2010
/Files/alantop/shutoff.rar

// shutoff.cpp : 定义控制台应用程序的入口点。
//

#include " stdafx.h "
#include < atltime.h >
#include < windows.h >
#include < stdio.h >
#include < conio.h >

void shutdown()

     // 从config中读取关机参数

    CString cs =    " shutoff " ;

    CString filename = " .\\config.ini " ;
     int offHour = ::GetPrivateProfileInt(cs,hour, 0 ,filename);
    CString min = " min " ;
     int offMin = ::GetPrivateProfileInt(cs,min, 0 ,filename);

     // 判断时间并关机

    CTime t = CTime::GetCurrentTime();
    CTime t1(t.GetYear(),t.GetMonth(),t.GetDay(),offHour,offMin,t.GetSecond());
    CTimeSpan ts = t1 - t;

    printf( " 还有%d小时%d分钟关机.\n " , ts.GetHours(),ts.GetMinutes() );

     int nHour = t.GetHour();

     char command[] = " c:\\windows\\system32\\shutdown.exe -s -t 60 " ;
     if (nHour == offHour && nMin == nHour)
        system(command);
}
