Hi Cynny,
A Windows Service cannot have a user interface (UI). This means your application probably cannot be converted to a service as-is. If your application does not have a UI then it should be less work to convert it to a service.
It may be possible to transfer the 'engine' of your application into a service, if no interaction with the user is required. The UI element of your application could then use this service as required.
That is, the 'engine' that does the actual work becomes a service. A separate UI to be run by the user as requried could then interact with this service.
Check out this

Cheers,
Paul
