Tout le monde connait la fonction GetSettings de VB6.
Elle pose un petit pb sous W2K : elle écrit sous une clé qui dépends de l'utilisateur. Si vous voulez que vos données soient communes à tous les utilisateurs, il faut écrire sous LOCAL_MACHINE et non USER.
Bref, voici une focntion GetSettingsEX() avec les même paramètre que GetSettings originale.
Remarque : si la clé n'existe pas, elle est créée automatiquement...
