Rad Posted November 13, 2006 Share Posted November 13, 2006 My goal is pretty simple, I want to send some messeges to all connections on my UDP server. The only problem is... the only connection i can see is $socket. I dont really see how this works, in the example does UDPBind() only take one connection? If thats the case, how do I know when its connected? I need some help UDPStartup() ; Bind to a SOCKET ;============================================== $socket = UDPBind("127.0.0.1", 65532) If @error <> 0 Then Exit While 1 $data = UDPRecv($socket, 50) If $data <> "" Then msgbox(0,"",$socket) MsgBox(0, "UDP DATA", $data, 1) EndIf sleep(100) WEnd Func OnAutoItExit() UDPCloseSocket($socket) UDPShutdown() EndFunc Link to comment Share on other sites More sharing options...
/dev/null Posted November 13, 2006 Share Posted November 13, 2006 (edited) My goal is pretty simple, I want to send some messeges to all connections on my UDP server. The only problem is... the only connection i can see is $socket.When you UDPRecv() data from a client the socket data is updated with the client information (ip, port, etc.). So, just use that socket to answer the client. There is no way to send data to all "connected" clients as there are NO established connections with UDP. UDP is a connectionless protocoll, so you'll never know if the client is still there to receive data. That's how UDP works and there is nothing you can do about it, except using TCP instead of UDP.CheersKurt Edited November 13, 2006 by /dev/null __________________________________________________________(l)user: Hey admin slave, how can I recover my deleted files?admin: No problem, there is a nice tool.

/dev/null Posted November 13, 2006 Share Posted November 13, 2006 When data comes in... create an array of client info... check the info against the info stroed to see if you already know this client... if not, add the info... then when you send... send to all in your "info array"Lar.It's still not possible to know if a client is still there to receive the data. If things go wrong, you'll end up sending data to a totally unrelated system if the IP address has been reassigned by the ISP. The only way would be to implement a kind of keep-alive between client and server, to inform the server, that the client is still there and to update the ip address in case of a reassignment.CheersKurt __________________________________________________________(l)user: Hey admin slave, how can I recover my deleted files?admin: No problem, there is a nice tool.
