UDP Receive Asynchronously

[dclamp]

I am trying to asynchronously receive UDP commands from my other program. I am using the code below which works great, once. But if i resend the command, it doesn't receive it.

How do I continuously receive UDP packets?

Private Sub startListening()
        ReceivingUdpClient = New System.Net.Sockets.UdpClient(listenPort)
        ThreadReceive = New System.Threading.Thread(AddressOf receiveMessages)
        ThreadReceive.Start()
    End Sub
 
    Private Sub receiveMessages()
        Dim receiveBytes As [Byte]() = ReceivingUdpClient.Receive(RemoteIpEndPoint)
        MsgBox(Encoding.ASCII.GetString(receiveBytes))
        'the end goal is a Case but message box for debugging
    End Sub
