title: RichTextBox Highlight All Instances of a Phrase
body: <p>In VB.Net, is it possible to highlight ALL instances of a phrase instead of only a single instance of it, for example:</p>
  
  <pre><code>    txtView.SelectionStart = txtView.Find("ERROR: Invalid command entered.")
      txtView.SelectionColor = Color.Red
  </code></pre>
  
  <p>This would highlight "ERROR: Invalid command entered.", however if my RichTextBox text is:</p>
  
  <p>ERROR: Invalid command entered. &lt; Only this line will highlight</p>
  
  <p>ERROR: Invalid command entered.</p>
  
  <p>ERROR: Invalid command entered.</p>
  
  <p>Alternatively, is there a way I can simply colour the line when I write it to the RichTextBox? Thanks in advance!</p>
