Environment: Win32, C++

Hello guys. This article presents some Win32 timer-related stuff. It consists of two classes:

  1. CTimerHost — that class is the source of “safe” timers. That means you can kill timer and be sure that you will not receive any timer notification from already dead timer. That timer should be used and destroyed only from the thread it was created.
  2. CTimerThunk<…> — represents thunk for receiving timer notifications.

These classes uses dynamic thunking technology. That means total absence of any static maps or lists. Enjoy.

Example of usage:

#include “sf_timer.h”
// for example in your CApp
CTimerHost g_TimerHost;
class CMyClass
{
public:
    CMyClass() : m_Timer(g_TimerHost, this, OnTimer)
    {
        timer.SetTimer(500);
    }
    void Stop()
    {
        timer.KillTimer();
    }
    void OnTimer(DWORD dwTime) {}
protected:
    CTimerThunk<CMyClass>   m_Timer;
};
