Remarques
Lorsque la méthode Start est appelée, cet événement est déclenché pour chaque source de trame infrarouge déjà connue du système, puis l’événement ÉnumérationCompleted est déclenché. Les nouvelles sources de trame infrarouge ajoutées ultérieurement déclenchent des événements SourceAdded supplémentaires.
