Convert classic 4D forms to dynamic forms

Automatically translated from English

Your forms may need to be changed depending on your customer or user needs. For example, the color black might be perfect for one user but not so much for another user (who sees blue as the ultimate perfection). Luckily, dynamic forms (introduced with 4D v16 R6) are here to help you handle your users’ preferences. But rewriting an existing form to a dynamic form could be a difficult task, and it’s not always easy to start with a blank page. Ideally, it’d be best to have a draft that can be modified and improved. With 4D v17 R3, it’s now possible to easily convert a classic 4D form (stored in .4DB file) to a dynamic form.
