/************************************************************************/
/*定时器使用
1. 建立定时器
SetTimer()函数为窗口建立一定时器，并每隔一段时间发出WM_TIMER消息
UINT SetTime(   HWND        接受定时器消息的窗口
                UINT        定时器代号
                UINT        时间间隔
                TIMERPROC   处理响应函数);
2. 删除定时器
BOOL KillTimer( int 定时器代号)
