Hi,

does anybody know what happens to a timer after resuming from hibernating mode of Windows? I am asking this question because I have timers which have a Interval of several hours.

Is the timer reset after resuming from hibernating? Or is it paused and just continued when resuming? Or are timers clock dependent (when I resume the computer 10 minutes later, the timer is exactly 10 minutes shorter)? Or isn't the timer not working anymore???


thanks

No, the timer is not reset. The timer stays active and the interval is honored. If you have a 30 minute interval, 5 minutes since last fire, then 20 minutes in hibernate, then you will have 5 minutes until the next WM_TIMER message fires into your app. As well, I found my system powering back on when the timer event fired....

Regards,
Russell
