    You can use SetTimer and KillTimer, but this functions need your class has a window and a message loop to handle a WM_TIMER message.

    Phogang,

    I would look at ::SetTimer(...). Reading the MSDN documentaion, I'm guessing the only requirement is that your application has a message pump. If your class has a single instance, you should be able to kludge something using ::SetTimer.

    Good luck,
    John Flegert

    There is no need for a message loop to use a timer

    You just havew to use one that is not based on messages!

    A WaitableTimer is directly supported via Windows API calls.

    Check MSDN for a starting point into the documentation.

    In theory, there is no difference between theory and practice; in practice there is.

    Use this function
    CreateTimerQueue();

    CreateTimerQueueTimer(
    PHANDLE phNewTimer,
    HANDLE hTimerQueue,
    WAITORTIMERCALLBACK pfnCallback,
    PVOID pvContext,
    DWORD dwDueTime,
    DWORD dwPeriod,
    ULONG dwFlags);

    with callback WAITORTIMERCALLBACK pfnCallback,

    A TimerQueue may or may not be prefferable over a WaitableTimer. Only the user knows for sure...

    To be able to answer the question you would need to provide some more information. Does your application has a message loop? Which resolution of the timer do you need? What is the purpose of the timer?

    Based on these information one can provide a fully satisfying answer. Without these it is more-likely just guessing in the dark...
