Copier une variable ou le contenu d'un contrôle en mémoire.

    Pour copier une variable ou le contenu d'n contrôle en mémoire, il faut utiliser des fonctions de l'API. Même si la commande RunCommand possède une constante qui permet de copier des données sur le clipboard, le tout est très dépendant des contrôles du formulaire. Vous devez mettre le contôle en focus, setFocus, et sélectionner le texte avant d'émettre le commande RunCommand.

    Incluses, quelques fonctions permettant de copier et de coller des données sur ou depuis le Clipboard.
