Well in D5 all you have to do is File > New and select the "Service" module in the list. Services generally run in the background usually transparently and apps generally run in the foreground.

Well Services generally speaking are built with one task in mind and usually don't have user interfaces to deal with. Although some of your anti-virus programs run as services instead as an application. Services can be ran before a user logins therefore setting up certain things such as authenication purposes or broadcasting to the network. Appplications Like LapLink will use a service to start before login so a user on a remote computer can login on the host computer from their computer.
What does it mean to be "Always On"?

Services are running in another security context than the loggen on users, and they are also active when noone is logged on. In addition to this, the SCM (service control manager) keeps track of the services, starts and stops them as needed and can even restart a service which has shut down unexpectedly (crash). But apart fom these differences, it's also just an application.

so its good to make an application particularly a Server application a service? that way when a crah occurs, the OS will restart the whole app? plus the resets and the autostart...services can have forms too right? like the Symantec autoprotect or SQL service manager?
