Sockets

[elziko]

I have made a simple clint/server system using sockets. I have the client
running on a PocketPC (not that thats important) and a server that listens
for a connection attempt from ther client and can recieve some bytes.

What I want to do now is change this to some sort of bi-directional comms.
Whats the best way to do this? Do I need to create a listener on the client
too listening on a different port? This, I guess, would make both apps a
client and a server. Or is there some other better way of doing it?
Obviously I cant use remoting!

I'm a little unclear as to what your trying to accomplish... Can you be
a little more specific. What to you mean bi-directional? Do you mean
that both ends have to accept connetions? Or do you simply mean, client
connects, get's response, sends data, gets response....?

Maybe, I'm dense - but it is important that others understand your
problem before making suggestions

Do you mean

that both ends have to accept connetions?

Yeah each app must be able to send data to the other when it sees fit. I
have started the way I described (having a listener in each app). However,
the connection still only works in one direction since one of the apps is
'Actively refusing' the connection.

Before I ask for anymore help am I doing this the correct way?

Well a socket is a two stream of data. Both ends, once the connection
is established can send and recieve over the same socket... But a lot
depends on what kind of data, and what kind of program. I am probably
sounding dense here - but without knowing what kind of app your trying
to write, I'm having a hard time comming up with suggestions. (I hope
someone else can jump in here and save me before I drown!

Sorry for being so vague... I'm not writing anything in particular, just
trying to get my head round it all. I found that I needed to look into
'BeginReceive' of the socket class to receive data asynchronously and I
found this excellent example:

Thanks for your help though.

Well, I'm glad you found something to help you... I was really starting
to feel inadequate
