Detecting idle users in Winforms

I'd like to pause my program if a user is inactive for 5 minutes. By inactive I mean hasn't pressed their mouse or their keyboard during that time (including outside the program too!). Any starting points?

Looks like I found solution for Your problem, look at:

How to detect a Winforms app has been idle for certain amount of time and user34660 answer,

For your app, must change:

const int MinuteMicroseconds = 60000;

to

const int MinuteMicroseconds = 300000;

It's just time, but in ms.

Works nice for my Windows Forms application.

This question is very similar to an old question:

.NET equivalent for GetLastInputInfo?

Which referenced a good article describing some different options in C#:

http://www.codeproject.com/KB/cs/uim.aspx

If you don't mind using P/Invoke and being limited to running on windows systems, then using P/Invoke to call GetLastInputInfo() is probably the simplest method of accomplishing what you want.

Within a timer you could p/invoke GetLastInputInfo() which will return the number ms since input was detected from the user, across all processes in the current session.

I've used the GMA.UserActivityMonitor library a while ago to achieve this.

you could override the WndProc and look for the WM_IDLE message
