The built-in Object Browser in Visual Basic, like other component browsers such as OLE View and XRay, is one of the more useful tools. But an even better tool would be customizable.

This article explains type libraries and the TLI object model, and shows how to use the collections to get information about objects, leading to the creation of a custom type library explorer.
