I have 2 sets of code for you to look at, both are available at PasteBin here:
First is my c# Socket server: http://pastebin.com/wvT4f19m
Second is my code within my AS3 application: http://pastebin.com/bKvabFSP
In the code, what I am trying to do is a simple Send/Receive to see what happens. If I open my application in 2 instances the c# socket server registers that they exist and all is fine!. If I close one of my instances, the c# server still thinks that the user exists and the socket isn’t closed.
My code is based off the example at : http://msdn.microsoft.com/en-us/library/fx6588te.aspx
In the MS example, the following lines are added to the SendCallBack() function:
handler.Shutdown(SocketShutdown.Both);
handler.Close();
These definately close the sockets, something I do not want to happen.
I am new at socket programming and it has taken me a fair amount of time to play with the MS example to get it working roughly how I need it. The only problem is the acknowledgement of user disconnects so that I can remove the user from the Clients list that I have set up in the server. Also, when disconnects are acknowledged, I can inform other clients.
thanks all!
Upon each attempt to send data to the user, I do a quick check for a successful transmission/Poll the user and if it fails, the user is removed from my server.
