>Can a mmBusinessProcess can be registred throw windows/web forms ?

If you use the business process object's ParticipatingObjectCollection, then yes. In your business process object, just use the Add() method of the collection to add a reference to each of your participating business objects. Then you can call the Windows Form method RegisterEventObj() passing a reference to your business process object (we used to call them "event" several years ago).

Best Regards,
