    Private Sub DisplaySelectionChange()
        selectionChangeRange = Me.Controls.AddNamedRange( _
            Me.Range("A1", "E5"), "selectionChangeRange")
        AddHandler Me.selectionChangeRange.SelectionChange, _
            AddressOf selectionChangeRange_SelectionChange
    End Sub


    Sub selectionChangeRange_SelectionChange(ByVal Target As _
        Microsoft.Office.Interop.Excel.Range)
        Dim selectedRange As String = Target.Address(, , _
            Excel.XlReferenceStyle.xlA1, , )

        MessageBox.Show(Me.Name & ": " & selectedRange & _
            " raised the SelectionChange event.")
    End Sub
