    <p>I apologize if I am way off base here, but perhaps this code sample I'll paste here could help you. This came from VBRocks...</p> <pre><code>Imports System Imports System.IO Imports System.Text Imports System.Text.Encoding '4/20/07 submission includes a line spacing addition when a control character is used: ' The line spacing is calculated off of the 3rd control character.
