Definizione delle operazioni in C++

In Gestione autorizzazioni un'operazione è una funzione o un metodo di basso livello di un'applicazione. Queste operazioni vengono raggruppate come attività. Gli utenti dell'autorizzazione di richiesta dell'applicazione per completare le attività. Un'operazione è rappresentata da un oggetto IAzOperation . Per altre informazioni sulle operazioni, vedere Operazioni e attività.

Nell'esempio seguente viene illustrato come definire le operazioni in un archivio criteri di autorizzazione. Nell'esempio si presuppone che sia presente un archivio criteri XML esistente denominato MyStore.xml nella directory radice dell'unità C e che questo archivio contenga un'applicazione denominata Expense.
