COM Object Sources

Any number of Automation objects and ActiveX controls might be available on your Windows system, depending on its configuration and the applications you have installed. In general, you can get information on the available COM objects by using the COM Object Viewer that comes installed with Progress. For more information on this viewer, see Using COM Objects In the 4GL."

Automation Objects

Since Automation objects are generally part of a stand-alone application that functions as an Automation Server, you must have the application installed that provides the Automation objects that you need for your Progress application. For information on the available Automation objects in a particular Automation Server application, see the documentation for that application or use the Progress COM Object Viewer.

ActiveX Controls

Three ActiveX controls come installed with Progress 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 Progress environment.
