Création d'une source de données dynamiquement

Question

Bonjour
Je lie une BD à un contrôle DataListBox par l'intermédiaire d'un contrôle adodc. J'associe au contrôle adodc une source de données système. Sur mon ordinateur, ca marche mais pour le faire tourner sur un autre ordinateur, il faut à chaque fois recréer à la main la source de données.

Le but est que cela se fasse automatiquement pour ne pas avoir à le faire sur tous les ordinateurs ou j'installerai le prog.

Comment faire??
