Question When a TCP byte(string) is received, it writes it, then scrolls down a bunch

[Xolitude]

Ok so subject says it all...


When I write a byte to the tcpserver, the console will print it out, but if there is any text after the returned byte, it scrolls down, also even if there is no string after it.


SERVER:

Imports System.Net.Sockets
Imports System.Text


Module Module1
    Dim server As TcpListener
    Dim client As TcpClient
    Sub Main()
        server = New TcpListener(8000)
        server.Start()


        Console.WriteLine("Waiting...")
        While True
            client = server.AcceptTcpClient
            Dim networkStream As NetworkStream = client.GetStream()


            Dim bytes(client.ReceiveBufferSize) As Byte
            networkStream.Read(bytes, 0, CInt(client.ReceiveBufferSize))


            Dim clientdata As String = Encoding.ASCII.GetString(bytes)
            Console.WriteLine(("Client sent: " + clientdata))
        End While
    End Sub


End Module

CLIENT:

Imports System.Net.Sockets
Imports System.Text


Public Class Form1
    Dim tcpClient As New System.Net.Sockets.TcpClient()
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        tcpClient.Connect("127.0.0.1", 8000)
        Dim networkStream As NetworkStream = tcpClient.GetStream()


        Dim sendBytes As [Byte]() = Encoding.ASCII.GetBytes("Is anybody there")
        networkStream.Write(sendBytes, 0, sendBytes.Length)
    End Sub
End Class

I've always used this same code and it's never scrolled all the way down like this before.. any help?

Your server code is decoding lots of 0-bytes from your buffer array. NetworkStream.Read is a function and return value is the number of bytes actually read, you have to use this number when you call GetString to only decode the actual data received, excluding all your 'unallocated' 0 value bytes.

Uhm... ok? So the help is..

This is the version of GetString method you have to use: ASCIIEncoding.GetString Method (Byte[], Int32, Int32) (System.Text)
Value for byteIndex parameter is 0, value for byteCount parameter is the number that Read function returns.

Still does the spacing thing...

What code do you have now in server?
