Bonjour,

J'ai lu cette discussion mais ça ne marche plus avec Access 2013 64 bits.
Rien ne se passe, la commande n'est pas exécutée
Pourquooooooooi ?

Bonjour,

normal car la déclaration d'API est différente en 64 bits !

A lire : Développer avec Office 64 bits …

Effectivement, en 64bit l'appel aux API est différent.
Le code ci dessous fonctionne: lancement de l'appli + attente de fermeture.
Cerise sur le gâteau: un paramètre permet d'afficher ou de masquer la fenêtre (0 = show, 5 = hide). Indispensable pour exécuter une boucle de batchs en tache de fond, sans parasiter l'affichage et le focus.
