Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie implementieren ISmartTagExtension , um Eine eigene Smarttagerkennung zu erstellen. Im Beispiel wird die Recognize -Methode implementiert, um jeden Smarttagausdruck zu erkennen, der in einer Zelle gefunden wird. In diesem Beispiel wird davon ausgegangen, dass Sie auf der Registerkarte .NET des Dialogfelds Verweis hinzufügen einen Verweis auf Microsoft.Office.Interop.SmartTag hinzugefügt haben.

Hinweise

Implementieren Sie die ISmartTagExtension -Schnittstelle, wenn Sie steuern möchten, wie Excel Smarttags in Arbeitsblättern erkennt.

Verbrauch

Dieser Typ soll nur in Projekten für Excel 2007 verwendet werden. Smarttags sind in Excel 2010 veraltet.
