I know this is straight forward, but somehow I couldn't get google to help me.
I want a timer operation that fires a event every second. I want to do this using threads and waitonsingleobject or something else instead of using system::timers::timer.
can anyone direct me how to do this.
Thanks in advance.

Not sure why you'd do this but... do something like this (more MFC-like, but I'm sure you can figure an equivalent)...
1) Create Thread
2) Within thread
-while() loop around a sleep/signal loop
-Sleep() for a period of time
-when done with sleep, signal with a PostMessage() to whatever window you want to alert of the timer
3) After execution, stop thread (gracefully!, or else you'll leak any memory there)

Not sure why you'd use WaitForSingleObject() unless you're trying to block the thread that's waiting on the timer... in which case, why have a timer on a different thread?

...Sorry for lack of code, headed to gym! cheers! :)

Solution 2

May be, you would like to know Waitable Timer Objects[^]. And its APIs for simple usage CreateWaitableTimer()[^], SetWaitableTimer(...)[^], WaitForSingleObject[^], CloseHandle[^].

Edit:
I've forgotten to state that there was Multimedia Timers[^], of course.

Yes, it provides more accuracy and precision.
It was in my mind when I started to write. Forgot it while considering to append to the end.
