        MessageBox.Show("The timestamp for the strokes is " +
            ((DateTime)e.NewValue).ToString());
    }

Private Sub Strokes_PropertyDataChanged(ByVal sender As Object, _
    ByVal e As PropertyDataChangedEventArgs)

    If (e.PropertyGuid = dateTimeGuid) And (TypeOf e.NewValue Is DateTime) Then
        MessageBox.Show("The timestamp for the strokes is " & _
