title: vb.net - richtextbox: Bold text between <b> strings
body: <p>I have a RichTextBox (a chat). I want to bold the names. How to do it?</p>
  
  <p>for example the richtextbox:</p>
  
  <pre><code>&lt;b&gt;Name1&lt;/b&gt;: Hello!
  &lt;b&gt;Name2&lt;/b&gt;: Hi!
  &lt;b&gt;Name3&lt;/b&gt;: Hey!
  </code></pre>
  
  <p>How can I change the names to bold and remove the  strings?</p>
  
  <p><strong>Name1</strong>: Hello!</p>
  
  <p><strong>Name2</strong>: Hi!</p>
  
  <p><strong>Name2</strong>: Hey!</p>
  
  <p>?</p>
