I decided to write very small program that would calculate how much time someone spends at computer. Not too sophisticated, just based on login-logout time and screen saver. Researching the subject I found that this days it should use System Event Notification Services (SENS) to be able to work on Windows Vista. And then I had very hard time figuring out how to make it work based on MSDN information.
What helped me is this article, particularly example.

The program is not written, but link is still good. And I tried example, it works.
Here I will post problems I and my colleagues met and solutions we found.
