Sunny,
You could do a number of things, but you won't be able to get a return
value back through the parameters, or through the return value. The entry
point for the application can only return an integer (which does not meet
your needs) and it can not modify the command line arguments. Any signal
that you send (perhaps an event, not the kind in .NET, but the
synchronization object) would have to be something that the other programs
actively listen for.
Because of these needs, it really is a better idea if you place it in a
component and have the clients or something else call the component. This
way, you can be more sure when the method completes, (instead of waiting for
an event, you just wait until the method call completes).
