HI Vin,
Thank you for the input. It works fine but I am still wondering how to pass a reference of an instanciated object in VB6. Suppose that the object is already in use in form A and we want to pass it to a form B. Form B change porperties of the object and Form A can see the changes made by form B to the object. In shirt, I want to use the same referenced object in two differents places.

Thank's again,
Christian
