Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie einen neuen Pfad erstellen und den Pfad zwischen zwei Komponenten einrichten.

Hinweise

Zusätzlich zum Einrichten des Datenflusses zwischen einer und einer IDTSOutput100IDTSInput100 Eingabe benachrichtigt diese Methode auch jede Komponente des Ereignisses durch Aufrufen OnInputPathAttached der und OnOutputPathAttached Methoden der Komponente.
