Exemples

L’exemple suivant crée une tâche d’insertion en bloc et définit certaines propriétés. La tâche d’insertion en bloc est ensuite supprimée du premier package et ajoutée au deuxième package. Les propriétés définies pendant qu’elle faisait partie du premier package restent inchangées.

Exemple de sortie :

The first package now contains 0 executables

The second package initially contains 0 executables

The second package now contains 1 executables

Remarques

Utilisez Join quand vous déplacez un conteneur ou une tâche d’un conteneur (source) vers un autre (destination). Vous devez supprimer l’objet du conteneur source à l’aide Remove de l’appel Join sur la destination.
