Tracking user activity

[Guest]

Hi,

How do you detect if there is (or not) user activity on a computer. Probably
the same technique as used in the screen saver. Can I subscribe to some OS
event.

You need to use WinAPI function GetLastInputInfo
(http://www.pinvoke.net/default.aspx/user32/GetLastInputInfo.html)

It shows user-idle state

Just hook the OS keyboard and mouse events. Here's an article about how to
do this in C#:
