定义:

SetTimer(    HWND hWnd ,//句柄 用0也行    UINT nIDEvent,//定时器的序号    UINT uElapse,//间隔时间 单位为毫秒    TIMERPROC lpTimerFunc//回调函数    );

KillTimer(    HWND hWnd,    UINT uIDEvent);

实例一:

#define AUTO_PLAY1VOID CALLBACK AutoPlay_TimerProc(  HWND hwnd,         // handle to window  UINT uMsg,         // WM_TIMER message  UINT idEvent, // timer identifier  DWORD dwTime       // current system time  ){bool clear_flag=clear_onepair();if (FALSE==clear_flag)KillTimer(hwnd,AUTO_PLAY);}void CLlk_wgDlg::OnBtnKill() {int slider_val;float show_time;show_time=slider_val=m_slider.GetPos();show_time/=1000;KillTimer(AUTO_PLAY);CString pTempInfo;pTempInfo.Format((" %5.3f 秒"),show_time);// 浮点数输出5个有效位，其中3个小数位.m_TimerShow.SetWindowText(pTempInfo);SetTimer(AUTO_PLAY,slider_val,AutoPlay_TimerProc);}

实例二:

//本例为windows后台程序 本来想用控制台 结果在控制台环境不能实现定时//已经测试通过#include "stdafx.h"#include "resource.h"#include <windows.h>void CALLBACK Timer(HWND hwnd,unsigned int a,unsigned int b,unsigned long c){MessageBox(0,"hello","test",0);//弹出对话框}int APIENTRY WinMain(HINSTANCE hInstance,                     HINSTANCE hPrevInstance,                     LPSTR     lpCmdLine,                     int       nCmdShow){// TODO: Place code here.unsigned int id=SetTimer(0,1,1000,Timer);//每1秒调用一次回调函数TimerMessageBox(0,"按我就停止","test",0);KillTimer(0,id);return 0;}
