To write effective Dynamic HTML applications, you must become familiar with the object model exposed by the browser that hosts the DHTML page. Figure 19-4 on the following page shows the complete Window object hierarchy. I'm not going to dissect every property, method, and event in this hierarchy; instead, I'll focus on the objects that are the most interesting and useful to a Visual Basic programmer.
Figure 19-4. The DHTML object model.
The Window object is the root of the DHTML hierarchy. It represents the window inside which the HTML page (which is represented by the Document object) is displayed.
