Hi GURU!

How to add timer to my class (my class does not derived form MFC).

}



Thank You.
Sorry for bad English.

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,

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.

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...
