' bon bah regarde ca (je sais plus ou je l'ai pompé, suremment dans les sources mais je l'ai largemment modifié...)
' pour t'en servir, c'est pas dure, 
' "SaveKey" crée une clée
' "GetString" lit une donnée chaine
' "SaveString" écrit une donnée chaine
' "GetDword" lit une donné numérique
' "SaveDword" écrit une donné numérique
' "DeleteKey" éfface une clée
' "DeleteValue" éfface une entrée et sa valeur
' "Run" écrit dans Software\Microsoft\Windows\CurrentVersion\Run pour mettre des programmes au démarrage

' bon voila, j'éspère que ca marchera (c'est testé WinXP seulement mais les APIs devraient marcher sur tout système > Win98...)
