Public Sub Close ()

Exemples

L’exemple suivant démarre une instance du Bloc-notes. Il récupère ensuite l’utilisation de la mémoire physique du processus associé à intervalles de 2 secondes pendant un maximum de 10 secondes. L’exemple détecte si le processus se termine avant 10 secondes. L’exemple ferme le processus s’il est toujours en cours d’exécution après 10 secondes.

Remarques

La Close méthode fait en sorte que le processus cesse d’attendre la sortie s’il était en attente, ferme le handle de processus et efface les propriétés spécifiques au processus. Close ne ferme pas les lecteurs et les enregistreurs de sortie, d’entrée et d’erreur standard au cas où ils sont référencés en externe.
