Gérer les codes VBA du classeur Excel activé par macro

Ajouter un module VBA en JavaScript via C++

Le code d’exemple suivant crée un nouveau classeur et ajoute un nouveau module VBA ainsi qu’un code macro, puis enregistre le résultat au format XLSM. Une fois que vous ouvrez le fichier XLSM dans Microsoft Excel et que vous cliquez sur les commandes du menu Developer > Visual Basic, vous verrez un module nommé “TestModule” et à l’intérieur, vous verrez le code macro suivant.

Sub ShowMessage() {
    MsgBox "Welcome to Aspose!"
}
