Beispiele

In diesem Beispiel wird ein Add-In zum Herstellen einer Verbindung mit WindowVisibilityEvents verwendet.Ersetzen Sie den Code in der Datei Connect.vb oder Connect.cs durch den untenstehenden Beispielcode.Führen Sie das Add-In aus, und öffnen Sie das Befehlsfenster und das Ausgabefenster in der IDE von Visual Studio, und schließen Sie sie anschließend, um die Ereigniserfassungsmethoden in Aktion zu sehen.Weitere Informationen zum Ausführen der Automatisierungsbeispiele finden Sie unter Gewusst wie: Kompilieren und Ausführen der Codebeispiele für das Automatisierungsobjektmodell.
