The section in the book that tells you how to use the Object Browser is an excellent introduction, but a better way to understand the objects, properties, methods, enumerations, and constants of IE is to look it up at Microsoft's MSDN web site. For example, the book demonstrates the use of the IE object using the Navigate method. MSDN explains that this method, "Navigates to a resource identified by a URL or to the file identified by a full path." But then you learn that there is also a Navigate2 method which, "Navigates the browser to a location that might not be able to be expressed as a URL, such as a pointer to an item identifier list (PIDL) for an entity in the Windows shell namespace." In general, always check MSDN for the documentation of Microsoft objects.

Although you can't embed active elements (such as buttons and listboxes) in the HTML itself (without making this an ASP or ASP.NET application, that is), you CAN include the displayed HTML along with active elements in a standard Windows form application. This is only possible if you go beyond the techniques explained in the book and implement Internet Explorer as an ActiveX component as explained here in this lesson.
