How to send data using a stream

I want to send data from the server to the client using sockets. How can I do that? Once I get the data into a dataset I would like to return the dataset to the client program using a NetworkStream. Here is the code I have so far.

Code:

---

    Public Sub listenerThread()
        Dim tcpListener As New TcpListener(8080)
        Dim handlerSocket As Socket
        Dim thdstHandler As ThreadStart
        Dim thdHandler As Thread
        tcpListener.Start()
        Do
            handlerSocket = tcpListener.AcceptSocket
            If handlerSocket.Connected Then
                SyncLock (Me)
                    alSockets.Add(handlerSocket)
                End SyncLock
                thdstHandler = New ThreadStart(AddressOf handlerThread)
                thdHandler = New Thread(thdstHandler)
                thdHandler.Start()
            End If
        Loop
    End Sub
    Public Sub handlerThread()
        Dim handlerSocket As Socket
        handlerSocket = alSockets(alSockets.Count - 1)
        Dim networkStream As NetworkStream = New NetworkStream(handlerSocket)
        Dim blockSize As Int16 = 1024
        Dim thisRead As Int16
        Dim dataByte(blockSize) As Byte
        Dim da As New DataAccess
        SyncLock Me
            Dim filestream As Stream
            filestream = da.GetData("SELECT * FROM CKMF01")
  ''is this where the data is sent back???
        ''filestream = File.OpenWrite("C:\upload.txt")
            While True

            End While
        End SyncLock
    End Sub

I see the checkmark.

Is this resolved?

Not yet. Not sure what you mean by check mark?
