Application?

Re:difference between Service and Service Application

Chris:

A "Service Application" is the actual program that runs when invoked by
Control Panel. It contains the stubs necessary to interact properly with
the
Control Panel. At design-time, it resembles a TDataModule that you can
drop new "Services" into. So basically, a Service Application can contain
(read: host) multiple "Services". And each Service can implement its own
functionality.

This is from the BCB online help:

Service Application - Creates a new NT service application. Once you have
created a service application, You will see a window in the designer that
corresponds to a service (TService). Implement the service by setting its
properties and event handlers in the Object Inspector.

Service - Adds a new service to an existing NT service application. Do not
add
services to an application that is not a service application. While a
TService object
can be added, the application will not generate the requisite events or
make the
appropriate Windows calls on behalf of the service.

I hope this explanation helps,
-Jim Rofkar.

Errrm ... sorry James, but services have nothing whatsoever to do with
Control Panel!
