email reader fail

[josh wood]

I am trying to create an email reader in vb.net 2008 but when I use the following code I get an error message saying
"Unable to read data from the transport connection: An established connection was aborted by the software in your host machine."

    Private Sub GetMailButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetMailButton.Click
        Dim tcpClient As New TcpClient()
        tcpClient.Connect("pop.gmail.com", Convert.ToInt32("995"))

        Dim netStream As NetworkStream = tcpClient.GetStream()
        Dim strReader As New System.IO.StreamReader(netStream)

        RichTextBox1.Text = strReader.ReadLine() & "<br />"

        Dim WriteBuffer(1023) As Byte
        Dim enc As ASCIIEncoding = New System.Text.ASCIIEncoding()

        WriteBuffer = enc.GetBytes("USER " & "testemail.email5" & Constants.vbCrLf)
        netStream.Write(WriteBuffer, 0, WriteBuffer.Length)
        RichTextBox1.Text += strReader.ReadLine() & "<br />"

        WriteBuffer = enc.GetBytes("PASS " & "testpassword" & Constants.vbCrLf)
        netStream.Write(WriteBuffer, 0, WriteBuffer.Length)
        RichTextBox1.Text += strReader.ReadLine() & "<br />"

        WriteBuffer = enc.GetBytes("LIST" & Constants.vbCrLf)
        netStream.Write(WriteBuffer, 0, WriteBuffer.Length)

        Dim ListMessage As String
        Do
            ListMessage = strReader.ReadLine()
            If ListMessage = "." Then
                Exit Do
            Else
                RichTextBox1.Text += ListMessage & "<br />"
                Continue Do
            End If
        Loop

        WriteBuffer = enc.GetBytes("QUIT" & Constants.vbCrLf)
        netStream.Write(WriteBuffer, 0, WriteBuffer.Length)
        RichTextBox1.Text += strReader.ReadLine() & "<br />"
    End Sub
