Question about Windows Services ??

I don't know if this question belongs here, its more of conceptual question.

What is the use of Windows Services

I have a business layer and a data layer which has to somehow run with that service and have a client application that will call that and do some functions. How can I accomplish this task

Any examples or tutorials, highly appreciated.

Thanks,

Hi, I have written a blog entry about windows services you might find interesting:-

I mainly use windows services on servers where a user interface would make little sense. You usually use them to check for something occurring/a trigger like a file added somewhere it shouldn¡¯t have been.

It is both business layer and data layer potentially, but never presentation (bar the output to the event log!).

I hope this answers your question.

I have been through your blog before, say if something is running as a service on Windows Terminal Services and that is also connecting to the database and other good stuff. What is the advantage over when client can use the same dll and call the database from there, rather than running as a service.This part is little confusing to me...

Say Business layer and services are two different projects or they can be done in one....as my application lot of clients will be connecting to the service....

can you give me a little code setup to use the service and the business layer say even adding two numbers that way....some example like that will help me understand more...

I'm still looking should my service project call the business layer or I should have it as one project....
