C/C++-Codebeispiel: Festlegen des Anwendungsnamens
In diesem Beispiel wird der Name der Anwendung festgelegt, die einer bekannten Aufgabe zugeordnet ist. In diesem Beispiel wird davon ausgegangen, dass die Aufgabe "Testaufgabe" bereits auf dem lokalen Computer vorhanden ist und dass der Taskplanerdienst ausgeführt wird.
