Title: Property browser which displays properties of sub-objects in an Active X control

Abstract: A system and method for enabling a property browser to display properties of sub-objects of a control, such as an ActiveX control. The system and method further enables a user to manipulate properties of sub-objects of the control. The method determines the top level interface of the control and displays the top level properties at the top level interface in a property browser. The property browser also displays an indication of properties which are sub-objects, i.e., properties which themselves have properties. This indicator is typically a conventional plus sign which indicates further elements are available in a hierarchy tree of elements. When the user subsequently selects a property which is a sub-object, the method operates to read the interface of the sub-object property from the type library and then display further top level properties of the interface as necessary.
