title: VB.Net - Remove lines longer than 5 characters
body: <p>Suprisingly i haven't found any threads online about this....</p>
  
  <p>In my TextBox1 i have this:</p>
  
  <pre><code>computer
  desk
  alphabet
  sex
  pencil
  book
  apple
  </code></pre>
  
  <p>I want to remove all lines that have more characters than <code>5</code>, so this will remain:</p>
  
  <pre><code>desk
  sex
  book
  apple
  </code></pre>
  
  <p>This seems like a job for Regex, but i don't have any idea how to do it.</p>
