Esempio

L'esempio di codice seguente illustra come implementare ISmartTagExtension per creare un sistema di riconoscimento smart tag personalizzato. L'esempio implementa il Recognize metodo per riconoscere ogni termine smart tag trovato in una cella. In questo esempio si presuppone che sia stato aggiunto un riferimento a Microsoft.Office.Interop.SmartTag dalla scheda .NET della finestra di dialogo Aggiungi riferimento .

Commenti

Implementare l'interfaccia ISmartTagExtension se si vuole controllare il modo in cui Excel riconosce gli smart tag nei fogli di lavoro.

Utilizzo

Questo tipo deve essere utilizzato solo nei progetti per Excel 2007. Gli smart tag sono deprecati in Excel 2010.

Proprietà

ExtensionBase

Ottiene l'oggetto che viene esteso da questo oggetto IExtension.

(Ereditato da IExtension)

Metodi

Recognize(String, ISmartTagRecognizerSite, ISmartTagTokenList, SmartTagRecognizeContext)

Cerca nel testo della cella i termini riconosciuti. Questo tipo o membro deve essere usato solo nei progetti per Microsoft Office System 2007. Gli smart tag sono deprecati in Office 2010.
