How do I make a chat room that multi clients will be connecting to at once. Im trying to add a ping/pong method which is just msgbox that tells the user if the message was received. I know that you need a background worker for this but how do i handle all the msgs that are going back and forth to all the clients that are connected to the server

I want to develop a chat application with a server/client model, opening TCP or UDP sockets in VISUAL BASIC 2008. Is there a working example I can download, or some code to help me with this project? [code]Now, instead of 127.0.0.1 I should put some variable or something that keeps the IP address of the target machine?

I am using Office 2003 with VS2008. I am trying to add appointments to a brand new calendar in public folders. Adding the first appointment works fine. However each and every other appointment from that point, is deleted when I add another one. Here is the code, that I am using.

So, in another related post, i got the chat to send to a java server, cool.Now, it's a matter of sending it back to VB.on the server side of things, (in java), I am using the following

i have lots of confused ideas like should you transfer files using tcp? Example: I was thinking, I connect to server from client, open file in binary, division by packet size(bytes), send first packet to server, get request if file was delivered succesfully, send next packet. If I do it this way i would need something to know/increase packet size.
View 5 RepliesI am building a client-server type applications and they are communicating over sockets. This is the first time I am doing such a program and I have been learning off a web example and thought I understood it all but it would appear I am missing something as it starts to work then errors. Here is what I have:
VB
Dim serverSocket As New TcpListener(ListeningPort)
Dim clientSocket As TcpClient
Dim netStream As NetworkStream
Dim BytesFrom(1024) As Byte
Dim DataFromClient As String
[Code] .....
All of the above works and if I open up a telnet command window I can connect to my machine running this code on my specified port and in the command prompt window 'IDENTIFY' appears as it should from the above code. But it then gets to this block an errors on the second line:
VB
'RECEIVE FROM CLIENT
netStream = clientSocket.GetStream()
netStream.Read(BytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))
DataFromClient = System.Text.Encoding.ASCII.GetString(BytesFrom)
Now as far as I can tell it shouldn't be processing the first line
[ netStream = clientSocket.GetStream() ]
Until I send something back from the client because then going on to the second line its trying to process something that isn't there yet.
The actual error I get is:
Specified argument was out of the range of valid values. Parameter name: size
On the line:
netStream.Read(BytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))

View 3 RepliesWe have a small service shows continuous nonpaged pool bytes increase from the moment it is started. This is only on a 2008 server (all the others work fine).
The service basically connects a socket to a client to see if it's successful and then closes (most code omitted):

I have been developing an async socket connection server and client program. I have been testing it, and noticed that if I connect to the server from my client and then disconnect. Upon reconnecting I am on a different port(local IP still). This is fine, however when I go to send a message, and the server trys to update all the clients, it eventually hits clients that do not exist anymore. I get the SocketException 10054, and upon connecting/disconnecting enough, it no longer works at all. My question is how do I clear out these no longer useful sockets from the server? I am doing currentsocket.Shutdown(SocketShutDown.Both); and then a currentsocket.Close(); after that. When a user disconnects.

I built a chat program using Socket (winsock2005dll) but it did not work well on internet, I've heard that using system.net is more powerful

View 10 RepliesI have made a GUI for my chat program and I'm going to finish the server stuff later. I am using Emoticons ( ) in both ASCII form and picture form. The ASCII ones work perfectly. I have taken the picture ones and put their pictures on buttons so their click event copies and pastes the picture to the rich text box I'm using for text input, but when i hit the submit button, it doesn't copy the picture.I'm using this code to copy the image from the buttons:
Clipboard.Clear()
Clipboard.SetImage(Me.btnSmi.Image)
Me.rtbIn.Paste()
ive tried making it so it copies the picture from the rich text box but that didnt work. i tried declaring a global variable (imgEmo as image) and the setting the variable = to what ever emoticon button is pushed at the time (click event) and using the following code in the submit button's click event:
Clipboard.Clear()
Clipboard.SetImage(imgEmo)
Me.rtbChat.Paste()
This is the code for my submit button:
rtbChat.Text += ((txtIn.Text + (" --") + (TimeOfDay)))
As a side problem, how do i make it so that every time i hit the submit button it starts a new line and formats the comment like this:
James says: (what ever the message is) --(TimeOfDay)
Kristie says: (What ever her message is) --(TimeOfDay)
I understand that for her answer to be there i need a server and all sorts of other code but i am not interested in that yet. I just need that format.
(Name) says: (string) --(Time)
(Name) says: (string) --(Time)
The name is coming from a separate form, the login form, and it is displayed in the top of my main form as "-- Welcome (Name)". i used the text changes event of the main form to then close the login form. I tried using this line of
'This was a global
Dim strNom As String = Login.txtUrn.Text
'in the submit button's click event
rtbChat.Text += ((strUrn) + ("says: ") + (rtbIn.Text) + (" --") + (TimeOfDay))
strUrn = strNom
This did nothing, in the chat box it returned "says: (message) --(TimeOfDay)".

View 1 RepliesIm working on this one application/chatter. What it does, theres a server, and lots of clients. Client sends data to server, server process's it, and the client receives the data (unless its a command, like /process username). Heres my problem. My client has a login feature, like yahoo. Client sends username/password to server. Server goes through list of usernames. Then sends it to client, wether it matches. But my client doesn't receive the data. Can anybody fix this, with my client code provided? Let me know if you need server code, and the extra script files/vb files. [Code]
