Comentários

Quando você cria um ListObjectChangeHandler representante, você identificar o método que manipulará o evento. To associate the event with your event handler, add an instance of the delegate to the event. O método do manipulador de evento é chamado sempre que o evento ocorre, a menos que você remova o delegado. Para obter mais informações sobre delegados, consulte Eventos e representantes.

O exemplo de código a seguir cria um ListObject e um Change manipulador de eventos. Para elevar a Change evento, adicionar texto a uma das células a ListObject e pressione ENTER.

    Microsoft.Office.Interop.Excel.Range, _
    ByVal changedRanges As Microsoft.Office.Tools.Excel.ListRanges) _

    Dim cellAddress As String = targetRange.Address( _
        ReferenceStyle:=Excel.XlReferenceStyle.xlA1)

    Select Case changedRanges
