Comment puis-je définir les options régionales dans une application Visual Basic 6.0?

Question

J'ai une application VB6 qui est dans l'environnement de production en ce moment, cette application lit les paramètres régionaux de l'ordinateur; mais maintenant, j'ai besoin de définir un autre paramètres régionaux pour l'application sans changer les paramètres de l'ordinateur.

Comment puis-je définir globalement les nouveaux paramètres régionaux avec le plus faible impact? Y at-il une méthode de configuration (ou quelque chose comme ça) pour le faire?

Dependsing sur ce que vous essayez réellement de réaliser, vous pouvez essayer d'appeler SetThreadLocale() dans votre procédure de démarrage.
