TCP problems in C#

[Invictus3593]

I've got a small LV TCP server program writing a string to the stream and then on the client side (written in C#), when I read the stream every 20ms, it comes back jumbled after the first read.

For instance, if I wrote a string "a b c" to the stream, it would read like something this for the first four iterations (each line is what is read at 20ms):

"a b c"
" ca b"
"b ca "
"ca b "

Here's the server code, really simple LV server, went off a youtube tutorial


Here's the C# code:

private void timUpdate_Tick(object sender, EventArgs e)
        {
            //update revolutions X and Y and the Gyro Angle every 20ms from the server string value
            //and make sure the connection is solid, otherwise update connection
            Byte[] info = new Byte[Client.ReceiveBufferSize];
            try
            {
                int rData = stream.Read(info, 0, System.Convert.ToInt32(Client.ReceiveBufferSize));
                RobotData = System.Convert.ToString(rData);
            }
            catch (System.IO.IOException)
            {
                lblConnectInd.BackColor = System.Drawing.Color.Red;
                Log("The robot ended the stream.");
                stream.Close();
                Client.Close();
            }

            //split string into X, Y and angle
            strRevX = RobotData.Substring(0, 2);
            strRevY = RobotData.Substring(5, 2);
            strAngle = RobotData.Substring(8, 2);

            //update values recieved in GUI
            lblX.Text = strRevX;
            lblY.Text = strRevY;
            lblAngle.Text = strAngle;

            //convert separated strings into doubles
            Double.TryParse(strRevX, out dblRevolutionsX);
            Double.TryParse(strRevX, out dblRevolutionsY);
            Double.TryParse(strAngle, out dblAngle);


            //make sure we're still connected
            if (Client.Connected == true)
            {
                lblConnectInd.BackColor = System.Drawing.Color.Green;
            }
            else
            {
                lblConnectInd.BackColor = System.Drawing.Color.Red;
                timUpdate.Stop();
            }
        }

Does anyone know how to fix this or what I'm doing wrong? I need a quick read time to get accurate data..
