Chat client/server

Hi, i am pretty new at programming, and to start me off, i would like to create a small chat server/client, but i dont know how to go about it. Can someone please show me an example of a server recieving data from a client, and then sending that data again to all clients? This would be of great help to me, as i need a kickstart off.

Can't say exactly, I haven't much spare time at the moment.

I will add all new userlibs/dll's this week, and after that the next code-archive should be done. But if it should become a well-done release, than all the codes must be checked with PB3.90.... :roll:

I cant seem to find any examples on a chat client/server, and, all the advanced sources, and some of the sources in the purebaisc example directory doesnt work :-\, error messages come up like "AllocateMEmory function error: too many parameters", and "Function not found".

damn your right
there was one on http://www.reelmediaproductions.com/pb
but Paul have pulled the plug on the resource site

Well for now you can mess with this German one, i found on the German Forum:

Start the server and then as many clients as you like: >>Click Here<<

Best regards

ok then, for now ill just create a client to connect to an IRC server. HOwever, i believe you need to send something to the IRC server before you can join, your name, etc..., however i dont know what order/where/how you send this to the server. If someone could give me what you need to send, that would be a great help.

Whats wrong with the one i pointed you to ?

Mess with that one first and get the basis.
you have to read up on how IRC, works and stuff, chat like the one i pointed is more simple.

Anyway it's your call.

Best Regards
Henrik

Found this somewhere here in the forum:

http://www3.sympatico.ca/airblazer/IrcEngine.zip

This one is a good irc engine written in PB.
Big source though..

thank you. I did not use that german one because i cant read german, plus i now have tha basic grasps. i have one last, noobish question. How would i append a string infront of another string? e.g. put "name: " in front of "hello" to make "name: hello"

Edit: and how do you send the message to all of the clients connected? i dont understand the german server example system of doing it..

a.s = "world"
b.s = "hello "+a.s

The German use a linked list

Code: Select all

NewList Client.l()

When it sends "SendNetworkString()"
it walkes through every single one on the list and sends the Text
Linkedlist is very powerfull for this kind of stuff
Read in the help about Linked list
** Press F1 **

Try this from the help and ad some Friends
it's the same way the German server uses:

Code: Select all

NewList Friends.s() 
  
  AddElement(Friends()) 
  Friends() = "Arnaud" 
  
  AddElement(Friends()) 
  Friends() = "Seb" 

AddElement(Friends()) 
  Friends() = "dwfait" 
  
  ResetList(Friends()) 
  While NextElement(Friends()) 
    Debug Friends() ; Display all the list elements 
  Wend

The German Server procedure look like this:

Code: Select all

;Send to All 
Procedure SendToAllOthers(ID, Text.s) 
 
 ResetList(Client()) ; Resetes to the  start of the list
 
  While NextElement(Client()) ; Walkes through all Clients of the list 
 
 ;* The ID is the client who send the text to the server in the first place 
    If Client() <> ID  
      SendNetworkString(Client(), Text.s) 
    EndIf 

  Wend 

EndProcedure

And btw of course you could ad strings together in blits, but but never mind.
