As I am sure many of you are aware that Project Server provides an event infrastructure that developers can create their own events for key pre and post events that occur on the server. Mike Shughrue from the Project's Center of Excellence has provided the attached sample code that is a great example on how to register events and how to create event handlers. I use this tool to register my events opposed to using the UI on the server.
