Detect computer's IDLE mode

[MIke Kansky]

I need to detect when user's computer goes to idle mode.
I also need to detect when user's computer comes back from the idle mode.

I have an application running in Sys Tray that should let the server know
that the user is inactive / active.

Any advice/resource please?

If you're processing data via a thread, just set the thread to the lowest
or low priority - Windows will automatically schedule the thread to be run
whenever there are free cycles.
