Scheduling design

Hi there,

I'm building an application that will run various reports according to given schedules.

My question is - what is the best way to implement a scheduler ?
The ideas I came up with were :

1) Creating a service for the application
2) Using windows scheduled tasks
3) Minimizing the application to the notification area in the bottom-right of the taskbar , and let it just sit in the memory and run the reports on its own.


I'm not sure if these ideas are any good.. it's just what I came up with.


Thanks.
