Bonjour a tous,

J'essaye de realiser un programme multilangue a la compilation. Pour ce faire je definis mes variables dans un fichiers que je choisi a la compilation en fonction d'une macro predifinie. Les messages multilangues sont uniquement des messages d'erreurs. Ils sont donc inclus dans un unique fichier, qui est lui inclut dans de nombreux autres.
Mon message d'erreur est le suivant :
