Eric,
>I put the MS Explorer as an object in a form. I would like to trap if the user did a selection (clic an hyperlink). Is it possible ?
If using the Web Browser control that comes with VFP6, you can add code into the BeforeNavigate2 method to trap the user clicking on a url, examine the url, put up a messagebox, whatever. Follow with DODEFAULT() to allow the navigation to proceed.
