Reading Event Logs

I have ben playing for a couple of weeks now. I have written a service that reads the event logs, but all I want it to do is read the latest events.

At the moment it reads all events of a certain source, what I want to do it have the service run every 3 - 5 seconds and look in the event logs and read the latest events not all of them.

Is this possible ?

Thanks in Advance.

I've got round this now, all I am doing is checking for entries made that day.

Its not clean but it works.

Paul.
