我现在项目是一个控制台程序，用到的Win32API都是与界面无关的，今天需要加入定时器刷新的功能，由于没有消息循环，所以WM_TIMER消息应该如何处理呢？综合了下网上找到的资料，写了个简单的demo,个人以为这种在一个线程中创建定时器，再通过指定的回调函数来处理定时器触发的模式是比较好的。

#include <windows.h>

#include <stdio.h>

#include <conio.h>

int count =0;

VOID CALLBACK TimerProc(HWND hwnd,UINT uMsg,UINT_PTR idEvent,DWORD dwTime)

{

count++;

printf("WM_TIMER in work thread count=%d\n",count);

}

DWORD CALLBACK Thread(PVOID pvoid)

{

MSG msg;

PeekMessage(&msg,NULL,WM_USER,WM_USER,PM_NOREMOVE);

UINT timerid=SetTimer(NULL,111,3000,TimerProc);

BOOL bRet;

while( (bRet = GetMessage(&msg,NULL,0,0))!=0)

{

if(bRet==-1)

{

// handle the error and possibly exit

}

else

{

TranslateMessage(&msg);

DispatchMessage(&msg);

}

KillTimer(NULL,timerid);

printf("thread end here\n");

return 0;

}

int main()

{

DWORD dwThreadId;

printf("use timer in workthread of console application\n");

HANDLE hThread = CreateThread(NULL,0,Thread,0,0,&dwThreadId);

_getch();

return 0;

}

GetTickCount可以到18－20ms精度
timeGetTime可以到1ms精度

QueryPerformanceFrequency 配合 QueryPerformanceCounter可以做到很高的精度
