“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。”

demo:

#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)
  {
   printf("Error:the thread will quit,error id is %d/n",GetLastError());
   break;
  }
  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,NULL,0,NULL);
 _getch();
 return 0;
};

本人在了解了作者的意图以后，也做了一个类封装：

#include <Windows.h>
#include <stdio.h>
#include <conio.h>

class CTimer
{
public:
 CTimer();
 void CreateTimerThread(int* pi);
 static DWORD CALLBACK TimeThread(PVOID pvoid);
 static void CALLBACK TimeProc(HWND hWnd,UINT uMsg,UINT_PTR idEvent,DWORD dwTime);
};

CTimer::CTimer()
{
}

void CTimer::CreateTimerThread(int* pi)
{
 HANDLE hand = CreateThread(NULL,0,CTimer::TimeThread,pi,0,NULL);
}

DWORD CALLBACK CTimer::TimeThread(PVOID pvoid)
{
 int* pi = (int*)pvoid;
 int itm = *pi;
 MSG msg;
 PeekMessage(&msg,NULL,WM_USER,WM_USER,PM_NOREMOVE);
 UINT timeid = SetTimer(NULL,111,itm,CTimer::TimeProc);
 BOOL bRet;
 while ((bRet = GetMessage(&msg,NULL,0,0))!=0)
 {
  if (bRet == -1)
  {
   printf("Error:the thread will quit,error id is %d/n",GetLastError());
   break;
  }
  else
  {
   TranslateMessage(&msg);
   DispatchMessage(&msg);
  }
 }
 KillTimer(NULL,timeid);
 printf("thread end here/n");
 return 0;
}

void CALLBACK CTimer::TimeProc(HWND hWnd, UINT uMsg, UINT_PTR idEvent, DWORD dwTime)
{
 printf("WM_TIMER in work thread count/n");
}

int main()
{
 int iTime = 1000;
 int* pi = &iTime;
 CTimer* ptime = new CTimer;
 ptime->CreateTimerThread(pi);
 _getch();
 return 0;
};
