One more try on Delegates

Hello everyone,

I am attempting to learn more about delegates and their role in VB.Net.

Say you have a service class (Server) and a client session class (Client).
When a consumer makes contact with the the service (say via sockets), the
server will spawn a new client instance and have it deal with the consumer
directly. The first thing you would want the consumer to do is present
credentials and authenticate. The server knows how to connect to the
database, and so it should be the one responsible for the authentication.

One approach to take would be to create a property in the client that points
to the server

friend writeonly property Server as Server
end property

function Authenticate(Username, Password) as boolean
if server.authenticate(UserName, Password) then
end if
end function

I am fine with that type of logic, but wouldn't this be a good use of a
delegate function? If so, how would I make use of such a concept. If not,
what are delegate functions really for?

Thanks for the help
