It can run as a console app or as a windows service. What happens if the power goes out doesn't have any relevance to my original problem. UPS, would be my first guess.

It has to run 100% of the time as it does a lot of stuff. It is a router for Point-of-Sale transactions. It routes POS requests between multiple POS stations and the clearing operator that performs all the credit/debit card payments. This application of mine keeps track of all the transactions that are performed and at precise moments most close some batches and reconcile all the transactions with the clearing operator. All those totals and counts are maintained in the memory and I need something to trigger batch close operations at precise moments of the day. So, it doesn't do only the events I was talking about but lots of other stuff. -----Original Message----- From: Discussion of advanced .NET topics.

You could write a C# program that manipulates the other objects and structures anyway you want. You could schedule that using the at command (windows task scheduler) and even include a set of command line parameters for it to run and decide what to do internally. -----Original Message----- From: Discussion of advanced .NET topics.

Could you elaborate on your second solution? Thanks. -----Original Message----- From: Discussion of advanced .NET topics.
