How can I tell if the system is 'idle', or the screen saver is
running, or the machine is locked?
I am writing an application that could really benefit from knowing
this information. During 'idle' time, I could do some of the slightly
heavier processing; during the 'working' time, I would display the
non-intrusive notifications that I don't want my customer to miss.

I see that I can apparently set the thread priority of my background
process to 'ProcessPriorityClass.Idle' and it should only kick off
when the system is idle, but I'm not certain if this is the 'best'
way... it sounds good, though.

Just some URLs or mention of some API's would be sufficient.

Thanks.

I would strongly recommend going with setting the priority of the thread. Why try to reinvent the wheel, when Microsoft has already done the dirty work for you?

I cannot read the language that the comments were written in, but the
code is completely clear.

Thank you very much for this sample.

VB.NET is the language everybody here is speaking.
