You would need to use a Timer control and keep track of what you consider "using."

No, I don't think this "naive" Approach is "good".
Hard to keep track (even more with WinForms cause lack of Routed Events), hard to make it "performant" + the os already keeps track of Input events (idle) - just get the info there where the "screensaver" is looking (what Tadit Dash suggested in Solution 1)

Poor user... :-)
Instead of helping users to work, you are going to add hassles.

Yes, you are right. But I have seen the banking applications implement this kind of approach.
If you are inactive for sometime, the Session just expires. Even it happens for the Websites.

Sure, that I can understand, but this is a very different thing. Session should expire, because this is an important security feature. But nothing should close application without user's consent. An application should wait for a user any time the user wants; and the user should be able to continue to work at any time. If session is expired, the user should be able to reconnect. Not a problem at all.

Yeah correct. That's why I just suggested how to check User Inactivity. :)

Solution 2

Monitor using the mouse move event. If the mouse does not move for the alloted time period, close the application.
This could slow down your application to an extent as on every move of the mouse, time difference will be calculated.

The user can work using a keyboard along. But what's the difference? Anyone can also monitor keyboard activity as well.
This is not a problem. The problem is: this is a typical evil requirement — please see my comment to the question.

Agree. The ideal way of handling this would be monitoring at server side rather than client.
Close connections after a given timeout.
