DHTML Applications

Previous sections of this chapter covered the IIS application development project, which is a server-side Web development technology new with VB6.

This section turns to a second Web development technology that is also new with VB6, the DHTML project. Unlike an IIS application, an application created with DHTML runs client side, in the environment of the end user’s Web browser.

A DHTML page is implemented as an ActiveX DLL and support files that are transferred to the machine where the user’s browser resides. The object model for DHTML pages includes the following:

  • BaseWindow—Represents the browser and displays (but does not contain) the Document.

  • Document—Represents the HTML page viewed in the browser and contains the DHTMLPage and HTML elements.

  • DHTMLPage—Represents the DHTML runtime environment.

  • HTML elements—Individual elements of HTML functionality that reside on the HTML page. Such elements can either be defined by sets of HTML tags, or as HTML controls that you place on the DHTML Page Designer’s surface from the ToolBox. In a VB DHTML application, programmers can manipulate HTML elements in much the same way that they manipulate control objects in standard VB applications.
