title: Fastest method for copy list box Items to a RichTextBox
body: <p>So far i am using the following code to move the items of a list box to a <code>RichText box</code>.</p>
  
  <pre><code>  For k As Integer = 0 To ListBox.Items.Count - 1   
        RichTextBox1.Text = RichTextBox1.Text &amp; ListBox.Items(k) &amp; vbNewLine
    Next 
  </code></pre>
  
  <p>The problem here is that when i use like this the code take around <code>2</code>minutes for moving <code>5000</code> items. is their any fastest method for this operation?</p>
