Hi, is there any method to get my application notified about poom database changes E.g. the user adds a new appointment and my app gets notified or is there an event I can wait for
At the moment I do a query on POOM database in an interval but it costs unreasonably battery power and performance.

POOM notification on changing appointments?

This is a new feature in WM 5.0. I'm doing the same thing with contacts.

Read the section about Event notifications. Search for PIM_ITEM_CREATED_LOCAL in the Pocket PC 2005 SDK and you will find a nice example.
