Three ActiveX controls come installed with OpenEdge for Windows. These include a combo box, a spin button, and a timer control. For more information on these controls, see ActiveX Control Support.

Visual Basic Professional provides a starter set of ActiveX controls and includes basic documentation on working with ActiveX controls. Other commercial vendors and countless sources of shareware and freeware offer ActiveX control packages of varying quality.

CAUTION: The control vendor is responsible for following COM standards. Any deviation might result in a control that does not work in the OpenEdge environment.
