How to get newly selected item of a ListBox with multiple selection?

I find that the ListBox control does not provide all functions that exist in its Windows native counterpart.

For example, I have a ListBox with SelectionMode set to MultiExtended. I need to know its index when a new item is selected. But I failed to find what events to handle.

Another less-used function is set focus rectangle to a selected item when a ListBox has more than one items selected.

Or I might be wrong.

From MS Samples:
ms-help://MS.VSCC.2003/MS.MSDNQTR.2005JAN.1033/cpref/html/frlrfSystemWindowsFormsSelectionModeClassTopic.htm

Private Sub InitializeMyListBox()
   ' Add items to the ListBox.
   listBox1.Items.Add("A")
   listBox1.Items.Add("C")
   listBox1.Items.Add("E")
   listBox1.Items.Add("F")
   listBox1.Items.Add("G")
   listBox1.Items.Add("D")
   listBox1.Items.Add("B")

' Sort all items added previously.
listBox1.Sorted = True

' Set the SelectionMode to select multiple items.
listBox1.SelectionMode = SelectionMode.MultiExtended

   ' Select three initial items from the list.
   listBox1.SetSelected(0, True)
   listBox1.SetSelected(2, True)
   listBox1.SetSelected(4, True)

' Force the ListBox to scroll back to the top of the list.
listBox1.TopIndex = 0
End Sub

Private Sub InvertMySelection()

   Dim x As Integer
   ' Loop through all items the ListBox.
   For x = 0 To listBox1.Items.Count - 1

      ' Determine if the item is selected.
      If listBox1.GetSelected(x) = True Then
         ' Deselect all items that are selected.
         listBox1.SetSelected(x, False)
      Else
         ' Select all items that are not selected.
         listBox1.SetSelected(x, True)
      End If
   Next x
   ' Force the ListBox to scroll back to the top of the list.
   listBox1.TopIndex = 0
End Sub

Thanks for DMan1's reply. But the code does not answer my question.

Let me explain my problem in another way.

Say I have listbox that has just three items - item1, item2 and item3. And SelectionMode is MultiExtended.

I click on item1 and then hold down CTRL key and click on item3.

Now I have a problem. The SelectedIndex property is 0 which is item1. I want to know the item that was just clicked on - it should be item3 and SelectedIndex should be 2.
