mylistener = New TcpListener(MyIp.Any, Port)
mylistener.Start()
While True
If Not mylistener.Pending Then
Console.WriteLine("Awaiting Requests")
Else
listenerThread = New Threading.Thread(AddressOf listen)
Console.WriteLine("Accepting Request")
listenerThread.Start()
End If
End While
I'm having trouble with the listening loop. I've set my app up so that a proxy class is created and started the moment the form loads. With the While loop above, the code works fine and browser and console outputs are as expected. However, the form on which the proxy class is declared doesn't show. When I remove the While loop, the form shows, but apparently based on console output, the listener only functions as far as "Awaiting Requests" and doesn't do anything from that point on. Browser output also reflects this.
Public Sub listen()
Dim msg As [String]
Console.WriteLine("Handling Request")
While True
Dim mytcpclient As TcpClient = mylistener.AcceptTcpClient
Dim buffbyte(mytcpclient.ReceiveBufferSize) As [Byte]
Dim mystream As NetworkStream = mytcpclient.GetStream
If mystream.CanRead = True Then
mystream.Read(buffbyte, 0, mytcpclient.ReceiveBufferSize)
Console.WriteLine("Received stream")
End If
msg = Encoding.ASCII.GetString(buffbyte)
stopconn(mystream, mytcpclient)
Another question. The code above is part of the listen() method called to handle the request. At the end of the code, I'm calling a function stopconn(), passing the networkstream and tcpclient objects connecting me to the requesting client.
mystream.Write(ByteGet, 0, ByteGet.Length)
mystream.Flush()
mystream.Close()
mytcpclient.Close()
This is what happens at the end of the stopconn function. I assume I've terminated all connections to the client but somehow all new requests from the browser hang or supposedly get stuck in endless 'connecting' mode. I tried adding Exit Sub after calling the stopconn function but it didn't work. So how can I ensure I've cleaned up all unnecessary connections and return to the listening loop?
