Hi,

I would like to be able to detect computer inactivity in order to
launch some admin process ...

Is there a simple way like a windows event ... I would like something
that will not be CPU and time consuming ...

Thanks !
 
See GetIdleMinutes API function

Hi,
Thanks !

I think I've already check this API but to use it (I may confuse) I
have to check every X sec to see if it is OK or not ... I'd rather
prefer that someone send me an event ...

GetIdleMinutes should not be used anymore. Use GetLastInputInfo instead:

There is not event but you can check the idle time every n seconds (and if
the intended idle time is reached, you can send an event in order to have
one).

Thanks !
I will try.
I'm just scare about the time/cpu consuming of checking every n
seconds ...

As the function doesn't do a lot, the call won't take forever...
Well, 10,000,000 calls took 0.78 seconds here, so...

You use very little CPU time for such polling. Do not use a loop, but
instead a Timer (or you could use a loop in a thread, too -- with
Thread.Sleep to release time).
