VB.NET: Problem with too large XML data

Say when i click on "A" button, my program will receive the large XML data for "A" from the server...

1) However, i will only receive one section of data....
2) Then when i continue to click on "B" button, it will not receive "B" data
instead it will continue to receive the rest of "A" data...

My coding for receiving the data....

Code:

---

Dim tcpC As New TcpClient
 Public Function receive() As String

        Dim ascii As Encoding = Encoding.ASCII
        Dim networkStream As NetworkStream

        Try
            networkStream = tcpC.GetStream()
            Dim bytes(tcpC.ReceiveBufferSize) As Byte
            networkStream.Read(bytes, 0, CInt(tcpC.ReceiveBufferSize))
            Dim ret As String = ascii.GetString(bytes)
            Return ret
        Catch
        End Try
 End Function

How to solve the problem of getting large data...

Thanks

Most probably, that has to do with the TCP/IP packet size (that can vary a lot) - when you receive, you don't get all the data in one packet. You should wait for the complete stream of bytes, maybe a software data length header could help you.
