title: Repopulate a combo box
body: <p>This is how I populate the combo box:</p>
  
  <pre><code>        foreach(string s in entries)
          {
              string[] fields = someSplit(s);
              threadComboBox.AppendText(fields[0]);
          }
  </code></pre>
  
  <p>How would I remove all items and add new ones? I tried calling <code>Clear()</code>, but while it does remove old values, new ones don't get added.</p>
