Hi, totally new to Visual Basic programming here. I have a program (compiled from a .php script of all things) that reads a string of data from a server. This data is 106 bytes in length, starts with 0x00, 0x00, 0x42 and terminates with a CRLF (0x0D, 0x0A).
In VB I can read data from the server, but about 98% of the time I am unable to read the entire string, instead a number of bytes (random, but usually between 20 and 30) are dropped from the beginning. Very occasionally I get lucky and receive the whole string.
New data is available on the server every 8-10 seconds.
Here is a bare bones version of what I have scraped together from looking around he net, there are no error routines at present
Any pointers as to how I can read a full string every time?
Thanks,
ex-egll

Code:
Imports System.Net.Sockets
Imports System.IO
Module Module1
Sub Main()
Dim returndata As String
Dim TcpClient As New TcpClient
TcpClient.Connect("10.1.1.5", "1001")
Dim netStream As NetworkStream = TcpClient.GetStream()
Dim streamreader As New StreamReader(netStream)
Dim bytes(TcpClient.ReceiveBufferSize) As Byte
netStream.Read(bytes, 0, CInt(TcpClient.ReceiveBufferSize))
returndata = streamreader.ReadLine()
TcpClient.Close()
netStream.Close()
End Sub
End ModuleThanks,
