I am building a chat client/server. And I can connect and chat just fine, but when a user disconnects, the server does not recognize this and acts weird, often spamming the last message that was sent by the user..Also, it's like the client does not disconnect from the server even when I close the client app. Once I exit the program, VB acts like it is still debugging. Once the server is shut down however, I get this error:
IOException was unhandled:Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
serverStream.Read(inStream, 0, buffSize)I don't know how to make my client and server accept the fact that a client has disconnected...
For an answer to this questions I've been looking years from now, then I couldnt find it and now it's complicated. I am working on a project to fully manage a computer's connection, it can check IP, change it, etc. But, I really, really need a function to sucessfully connect/disconnect a PC from the ineternet without promps or other screens, IPCONFIG and DHCP command aren't useful!, im exploring RAS but couldnt come to anything yet
View 1 RepliesIm using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.

I have an ADSL connection that requires username password login (PPPoE). This looks just like a phone dial up connection dialog box.But all the codes i've seen for automatically connecting to internet, or even detecting a connection do not work.I'm looking for a way to have my software check for an active connection to internet, and absent that, to connect via the default connection.I'm on XP. I don't know if that makes a difference.I have set properties to save the username password and not to prompt for them. So if I double-click the connection it will connect without any dialog box.
