Bonjour craryb,
merci de m´ avoir repondu,
apres avoir ajoutee les classes de Typbibliotheque(Microsoft excel 11.0), c est cree automatiquement une classe CWorkbooks.h pour l interface Workbooks.Cette classe ne contient pas de Add-methode avec un seul parametre.
Voici un extrait de la classe CWorkbooks generee:
// Computergenerierte IDispatch-Wrapperklassen, die mit dem Assistenten zum Hinzufügen von Klassen aus der Typbibliothek erstellt wurden
