ActiveX Designers

A designer provides a visual design window in the Visual Basic development environment. You can use this window to design new classes visually. Visual Basic has built-in designers for forms and — in the Professional and Enterprise editions — ActiveX controls and documents.

Objects created from the classes you design in this fashion have separate design-time and run-time behavior and appearance, although many objects — such as forms and controls — look very similar in the two modes.

In addition to its built-in designers, Visual Basic allows third parties to develop designers for use in the Visual Basic development environment. These ActiveX designers work just like the built-in designers in Visual Basic, making them easy to learn and use.
