title: Fill a Textbox from a File
body: <p>I am making a Help-form for my application. A Help-form normally has a ListView on the left and a RichTextbox on the right. When you click on a Help topic in the ListView, the text in the RichTextbox is supposed to change accordingly. The text file is part of the application's resources.</p>
  
  <p>Any help will be much appreciated.</p>
  
  <p>Thanks.</p>
