title: Changing the forecolor and backcolor of text in a textbox
body: <p>I'm making a C++ code editor application using VB.NET. I'd like to change the color of the keywords as the user types it. Also I'm looking for a way to highlight some lines of the code.</p>
  
  <p>Is there a way to change the forecolor and backcolour of a piece of text inside a textbox or a rich textbox?</p>
