Structure declarations and prototypes for functions are contained within header files. Classes are user defined data types. The application can now render content using the browser engine found in IE 4.0. Compiling and running the code at this point will create a program that displays a Web page defined in the HtmlView class. We add database functionality by inserting the ADO Data Bound Dialog component.
ADO provides data access and manipulation based on a common programming model.
No coding is required to connect the data fields to the data or to wire the buttons to navigate the data source. A database file containing a list of select Web pages, which I created for a previous article , will provide the raw data for this case. The ODBC data source, named Articles, needs to be configured for ArticleBrowse to work. A great aspect of using ADO is the database can be local, inside a corporate network, or on the Internet. New information can be updated from a central location.
