title: Keeping objects selected when changing selection types
body: <p>I have a macro that allows people to select ListBox items using either <code>fmMultiSelectMulti</code> and <code>fmMultiSelectExtended</code>. The two options can be switched at any time using radio buttons. However, if someone selects a group and then changes the selection, the selection is cleared. Is it possible to keep the selection through the changing process?</p>
  
  <pre><code>Private Sub OptionButton3_Click()
     ListBox1.MultiSelect=fmMultiSelectMulti
  End Sub
  
  Private Sub OptionButton4_Click()
     ListBox1.MultiSelect=fmMultiSelectExtended
  End Sub
  </code></pre>
