title: Make Font Bold/Italic/Underline Visual Basic
body: <p>Ok I already have a Font Dialog that changes the font of the richtextbox and it works (although I don't know how to make the apply button of the dialog work)</p>
  
  <p>I also made 4 buttons for Bold, Underline, Strikethrough, and Italic.</p>
  
  <p>The method I have found most people using is </p>
  
  <pre><code>Dim boldf as NewFont(....) 
  </code></pre>
  
  <p>and then applying it to the selected text.</p>
  
  <p>Problem with that is that it changes the font to only Bold, it doesn't add it to the existing style. </p>
  
  <p>Please advise.</p>
