The Objective Toolkit forms engine works in concert with the ActiveScript Hosting Engine to provide a completely scriptable user interface. The ActiveHost Form Editing Engine is a scaled-down Visual Basic®-like editing and run-time environment that you can embed in your own applications.

The forms engine enables the end user to edit and script MFC graphical user interfaces interactively using a form-editing user interface. Adding forms editing to an application is as easy as modifying the parameters for the document template instantiated in the application's InitInstance() member.
