Public Sub Close ()

Ejemplos

En el ejemplo siguiente se inicia una instancia del Bloc de notas. A continuación, recupera el uso de memoria física del proceso asociado a intervalos de 2 segundos durante un máximo de 10 segundos. En el ejemplo se detecta si el proceso se cierra antes de transcurridos 10 segundos. En el ejemplo se cierra el proceso si todavía se está ejecutando después de 10 segundos.

Comentarios

El Close método hace que el proceso deje de esperar a la salida si estaba esperando, cierra el identificador del proceso y borra las propiedades específicas del proceso. Close no cierra la salida estándar, la entrada y los lectores de errores y escritores en caso de que se haga referencia externamente.
