RaiseEvent and Classes (need expert's help)

[israfil334]

Ok, so here i am all happy n stuff, working on a FTP Server in VB.NET.
Feel like I'm in paradise cause I recently switched over from VB6.

Heres the problem.

I have the following Classes

ServerClass
> which contains ListenerClass (private)
> which in turn contains ClientClass (private)

so its like ServerClass.ListenerClass.ClientClass

The server class contains a event, "InternalMessage"
ie. Public Shared Event InternalMessage(ByVal theMsg as String)

(don't worry i shall provide sample code...read on plz )

Now basically I'm developing a windows service, but I'm doing the actual developing as a console application to make everything easy.
so this console application basically creates the "server class"
and simply calls a serverclass.start to start up the whole FTP Server.
However I want the serverclass and its internal classes to be able to report back to the "Mother Application" which can be either a console application or whatever.
SOOOO, BASICALLY whan a remote host connects I want the ClientClass to be able to pass on a message to the Mother Application via what'ever means nessesary.
Heres the sample code.

Module Module1
dim withevents ftp as new serverclass

sub Main()
ftp.startservice
console.readline()
end sub

sub onMessage(ByVal theMessage as String) Handles ftp.InternalMessage
console.writeline(theMessage)
end sub
end Module

that was the mother application
these are the classes

public class ServerClass
Public Shared Event InternalMessage(ByVal msg as string)

public sub StartService()
raiseevent internalmessage("Starting Service")
dim LS as new ListenerClass
LS.Start
end sub

private class ListenerClass
public sub New()
dim client as new ClientClass
end sub
end class

private class ClientClass
public sub New()
'blah blah blah
'CODE NEEDED HERE TO CALL ON THE raiseevent internal message of ServerClass that was defined as FTP by the console application
end class
end class

so basically what im trying to do is, get the ClientClass to invoke the event of a an instance of serverclass. or ie. its Parent Class.
HELP PLEAAASE
Or if you have any other method of transporting messages "upwards" of the object hierarchy please do advise.
(and NO i dont want to pass down a "reporting type" object all the way down each time a new class is created.)

I will assume you left code out, but where are your declarations for your private classes in ServerClass? They need to be exposed to calling classes somehow.. right now (in the way you have posted your code) they are private and can't be created or used by anything but ServerClass itself.

yeah thats what I made it like.
only the serverclass creates the private classes.
the internal classes arent exposed.
I did this so that everything is in a way "automated" and all the mother application has to do is call the startservice method.

I forgot 2 add a few lines, srry about that.
heres the proper stucture of the ListenerClass

Class ListenerClass
public sub new()
end sub
public sub Start()
dim client as new ClientClass
client.dosomething
end sub
end class


srry bout that guys.

You would need to put the events you want raised to the main application in the ServerClass then, and when the private class events are raised, handle that in the ServerClass, which in turn raises the event to the main app.

ok im obviously doing something wrong here. erm could u give me a sample please?

[israfil334]

man i wish i could post my source code, but its all on my laptop and im @ work right now, not allowed to transfer any files onto the office comps. =\

[israfil334]

ps. im trying to pass a string from the ClientClass to the ListernerClass to the ServerClass and finally to the console app

[israfil334]

basically what i did was add a subroutine in each class called "MessageService"

Private Sub MessageService(byVal theMsg as string)
raiseevent internalmessage(theMsg)
end Sub

and whenever i create a ClientClass from within the ListenerClass i do this

dim newClient as new ClientClass
addHandler newClient.InternalMessage, AddressOf MessageService

i tried changing the AddressOf MessageService to Me.MessageService
but that didnt work either
I'm not getting any errors or anything, and the Events of the ListenerClass and ServerClass aren't getting invoked, I tried adding stops to check if they were being invoked.
so basically
when i do this from the ClientClass

its supposed 2 invoke a subroutine in the ListenerClass which raises its internalmessage event, which causes a subroutine in the ServerClass run which finally triggers the internalmessage event of the serverclass which is picked up by the console app.
