Description : In this book you'll start with the HTTP protocol. Unfortunately, the publisher couldn't attach two aspirin underneath the accompanying CD-ROM in the back of the book, but take it slow-it isn't too bad. The material is covered in Chapter 2, "HTTP: How to Speak on the Web," which can be read from beginning to end and can also serve as a reference guide to the HTTP protocol.We then move into DDE and OLE control of the Netscape browser in Chapter 3, "Interfacing to the Web with DDE and OLE." Although the chapter covers Navigator exclusively, other browsers (Spry's Mosaic and Microsoft's Internet Explorer, for example) are also controllable using DDE and OLE. However, their implementations of DDE and OLE are not covered in this book.
Chapter 4, "Using Web Browser Custom Controls," introduces a few of the many custom controls available to interface Visual Basic with the World Wide Web.
Next is coverage of CGI applications. If you don't know what CGI is, turn to Chapter 6, "The Win/CGI Interface," which covers the interface between Windows and CGI applications. In Chapter 7, "Creating CGI Applications in Visual Basic," you'll put this knowledge to use writing actual Win/CGI applications for Windows- or Windows NT-based Web servers.
One of the previously mentioned reasons to choose Visual Basic for Internet development included database accessibility. This is covered in detail in Chapter 8, "Database Connectivity: The WebGuest Application." In this chapter you design a complete guest book application similar to ones seen on most Web sites. In addition to entering information, users of the WebGuest application can also list and search information entered by previous registrants.
Chapter 9, "Connecting to OLE Servers: Using the Web as a Front-End to Schedule Plus," covers using OLE to link the Web and Visual Basic to other OLE-enabled applications. The application example presented in this chapter allows a doctor's office to accept and schedule appointments using their Web site. As appointments are created by the doctor's patients, they are entered into the Schedule Plus database for use by any other machine with access to the Schedule Plus data.
Chapter 10 continues the coverage of server-side applications with "Using OLEISAPI with the Microsoft Internet Information Server."
Chapter 11 provides a brief introduction to the role of Web Spiders and Robots and serves as the start of the section of the book covering client-side applications.
The first chapter in this section is Chapter 12, "QuoteWatcher: An Interactive Web Agent." In this chapter you create an application that retrieves price quotes for specified stocks and mutual funds. The quotes are obtained from a Web server that typically provides quotes in response to user input on one of the server's HTML forms. The QuoteWatcher application bypasses the need to use a Web browser and fill in those forms, however, by sending the proper requests to the Web server.
In Chapter 13, "Building an E-Mail Signature Generator," you build an application that constructs an e-mail signature file based on random quotations obtained from one of the many random quotation generators available on the Web. This signature file can then be used by your e-mail application to attach the newly generated signature to your outgoing e-mail.
Chapter 14, "WebSearcher: A Simple Search Tool," brings the concept of popular Web-based search engines to a client-side application. A simple search tool is developed that allows you to specify a Web page to search and the keyword for which to search. The WebSearcher then searches the specified page and any page to which it links for the keyword, providing a list of any "hits" it finds.
Finally, Chapter 15, "LinkChecker: A Spider that Checks for Broken Links," shows how to check a specified Web page for hyperlinks to resources that aren't accessible. This is useful if you administer a Web site and want to ensure that any hyperlink you place on your Web pages is valid.
