login

This is in regards to applications that run in the taskbar but should be applicable to standard apps, Winforms, WPF, etc.

Question: I am after some method (preferably via managed code) to be notified when a user either has their screen "locked" while my app is running and/or know when they log back in.

GMail Notifier does this sort of thing for example, if my PC is locked for a while when I log in again it shows a list of emails that arrived since locking the PC. I'm looking to replicate that kind of functionality.

Does anyone have any ideas on how to accomplish this?

The dynamic type in C# 4.0 is a welcome addition to the language.
