Classe de gestion du registre (lire/ecrire/supprimer/lister...)

Description

Salut, ce code est une classe qui permet diverses opérations sur le registre de windows :

-ReadValue ==> lire une valeur de clé de type BINARY, DWORD, SZ, MULTI_SZ ou EXPAND_SZ
-WriteValue ==> écrire une valeur (type BINARY, DWORD, SZ, MULTI_SZ, EXPAND_SZ,...)
-DelKeyValue ==> supprimer une valeur de clé
-DelKey ==> supprimer une clé
-CreateKey ==> créer une clé
-DoesKeyExists ==> tester l'existence d'une clé
-GetSubKeys ==> lister les sous clés (non récursif)
-GetKeyValues ==> lister les valeurs de clé d'une clé

Ce genre de code doit certainement déjà exister, mais bon, celui ci est une classe (ce qui doit réduire le nombre de codes identiques au mien ;)) et j'ai mis des exemples....donc bon....

Conclusion :


Voilà... en prime, des exemples pour
-lister les types de fichier
-obtenir votre serial windows
-lister les programmes uninstallables
-lister les programmes se lançant au démarrage

Bien sur, prévenez moi si il y a des bugs et commentez/notez svp ;)
