Use the SelectionChanged event to notify your application when the user changes the selected date. Use the SelDate property to get or set the selected date. The Date property specifies the date being browsed in the drop down portion of the control. Use the MaskOnEmpty property to specify the caption being displayed in the control's label when the SelDate property is empty.

The following sample prints the selected date:

Private Sub CalendarCombo1_SelectionChanged()
    Debug.Print FormatDateTime(CalendarCombo1.SelDate())
End Sub
