Exemples

L’exemple de code suivant crée un DtsEventHandler événement OnError dans le package. Ce DtsEventHandler conteneur contient deux exécutables et établit une contrainte de priorité entre elles. L’exemple de code affiche le nombre d’exécutables dans le conteneur, puis en supprime un et affiche à nouveau le nombre.
