Communications :: Write A Server That Can Communicate With Multiple Clients Through Tcp/ip?
Feb 10, 2010
I'm new to network programming and i'm trying to write a server that can communicate with multiple clients through tcp/ip, the clients need to communicate with the server to and with the other clients. Currently i've got a client server program that works fine for only one client:
[Code]...
I'll guess to accept multiple clients i have to create some clienthandler class at server side, but i have no idea which code it has to contain, i've already spend hours searching on google but didn't find anything usefull. Can somebody help me with this ?

I have been struggling to find a solution for this problem. What I need to do is build a server application that accepts tcp client requests from different clients running on same port say:1003. I experimented by using asynchronous mode call backs etc. but it disconnects once connection is established and does not respond for further requests from the same client.

I am facing a problem in VB .net Client/Server application where I am successfully able to talk between them using TCPListener and TCPClient class usage. However, when I try to connect another Client to the same server on the same welcome port, it errors out throwing an exception or behaves very unexpectedly.Isn't it true that the Server connection is on a WELCOME PORT for all the clients, and that each client connected gets a new port to carry on its communication with the server AUTOMATICALLY (according to the Tomcat webserver working)

I made a simple chat system that connects to a server with a client one on one. I'm not really sure how to get multiple clients with the server so that you can see everyone's messages. Here is the source code. The Server only accepts one client at a time.

I have been programming a TcpListener Program and I have everything working right! So far... Except that when I have multiple clients connecting to my Server... I used a try catch statement to catch the error and it says that tcplistener doesn't allow multi connections... think creating a new thread for each connection sounds like the most reasonible answer but I can't grasp the concept of it...
Here is my frmMain:
Imports System.IO
Imports System.Net

I have a ASP.Net VB.Net application, which I developed an deployed in about 2004. I have just upgraded it to a new server and IIS 6.0. The application requires users to login from IE it and maintains their State using sessions on the server. I would like the users to be able to have multiple browsers open, each running with unique data on their client system. Is this possible, if so, what do I need to do?

I teach programming at a high school and I have used VB 2005 Express (in a computer lab of 33 clients) for a number of years without a problem. However, this year I switched over to VB 2008 Express and now I am constantly having registration issues. I have found the following ...
1. You must re-register the product for every user on that client
2. Each client must have a unique registration key
3. You are allowed only 30 days of useage without registration
What is happening is I asked my students to register the application themselves. But we keep getting this registration request every time a student switches seats in the room. Now we are getting an error message that says we have had too many registrations from this IP address.Is there a registration key that will work on more than one computer? Is there any way around the registration issue?

How can I make a server application? How can I then create another application that is meant for the clients!? I have tried to look for something for over 3 months now. All that stuff about TCP/IP just is not working! Using TCP/IP I cannot connect to anyone out of my network! How can I make it so when you start the client application it will automatically connect you to the server. Then having 2 textbox's and one button that says "Send". One text box will have what has been send and recived and the other textbox will be what you type to then later send it! How can I make it work with up to five clients!?

I have a large class that I built to act as a TCP server for one of my silverlight applications. When a user connects it stores the tcp client into a table for later communication. The problem is that when I send data, with more than one client connected, it loops through both open TCP Clients but some how sends the data twice to the same client.... the other tcp client never receives his data. This isn't a logic issue as I can step through the code and see that it is clearly taking each individual TCP client out of the table and sending it the data. They all use the same port... could that be the issue? And if so how do I make it so that it can connect on one port then transfer to another? I have tried using different computers for connecting but still the most recently connected client receives all of the packets of data.
