bonjour
je vais vs donner ma source et pourriez vous me dire comment je pourrais créer un extension de fichier et lorsque je vais cliquer sur ouvrir ou enregistrer sous, ce soit inscrit dans fichier de type(dans la boite de dialogue en bas de nom du fichier) et lorsque j'enregistre je voudrais aussi que ce soit l'extension par défaut (sans avoir besoin de l'ajouter apres le nom du fichier)
voici ma source:
