UDP Receive Asynchronously

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?

vb.net Code:

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

Since the Receive method blocks until something arrives and the fact that it's in a worker thread, I believe all you need to do is wrap the receive in a do loop. I'm still kind of learning this stuff, so if nobody posts saying I'm not right, it means I'm learning real good.

VB Code:

Private Sub receiveMessages()
Do        
Dim receiveBytes As [Byte]() = ReceivingUdpClient.Receive(RemoteIpEndPoint)
        MsgBox(Encoding.ASCII.GetString(receiveBytes))
        'the end goal is a Case but message box for debugging
Loop
    End Sub

That did it! Thanks!
