15.0.0- Writing an Application

Writing an Application

In the first 14 chapters of this book, we've covered most aspects of ASP and had exposure and practice in using many on the techniques involved. Each chapter looked at a different part of the ASP technology, and demonstrated ideas using small, self-contained examples. In this chapter we'll set out to write a much larger application using Active Server Pages.

This application will make use of many of the different functions that we've already seen in this book. For example, we'll be using:

• Client-side scripting with JavaScript
• Server-side scripting with VBScript
• The ASP Request and Response objects, to communicate with the web client
• The ASP Session object, to manage a user session
• The ADO Connection, Command and Recordset objects, to manipulate information contained in a database

We'll build our application from the ground up, and as we do so we'll be able to see how these different aspects interact with each other in a 'real-life' environment. While this chapter won't explain every single line of code in detail, it will provide you with sufficient information to allow you to implement the application as-is, or modify it to suit your needs. You might also use it as a starting point or a guide to writing your own applications.
