Question

I created a server-client application using the asynchronous socket. I found the problem when closing a socket on the server, applications so closed. The procedure that I do to close the socket server is:

1. Terminate the listening thread.
2. Close the client socket is still connected to the server.
3. Close the server socket.

How to prevent the application is closed, when I close the server socket? Thanks

    Protected Friend Sub CloseServerSocket(ByVal IPAddress As IPAddress, ByVal socketPort As Integer)

    ' Terminate the listening thread. 
    If listeningThread.IsAlive Then listeningThread.Abort()

    ' Close the client socket is still connected to the server.
    For Each sock As Socket In workSocketList
        If sock.Connected Then
            Interlocked.Decrement(workCount)
            sock.Close()
        End If
    Next

    ' Close the server socket.
    serverSocket.Close()
    serverSocket = Nothing
End Sub
