PT Application Reusable Features

The PT application is designed not only to demonstrate important development techniques for key Microsoft technologies, but also to provide you with reusable features, such as JavaScript files and COM components, that you can adapt for your own applications. As you will see in discussions such as Components Designed for Reuse, the PT application is designed to be as generic as possible, using parameters and late binding in many places instead of hard-coding values.

The following topics list the reusable features in the PT application. As always, the BDG includes complete source code for you to review and use.

• Implementing the Menu Bar describes a way to build application menus dynamically with a Popup ActiveX® control populated with menu items (and event handlers for those items) that are stored in XML files and processed by XSL files.
• Reusable JavaScript discusses client-side scripts that you can adapt for tasks such as data validation, extracting parameter values from URLs, and populating HTML tables with XML data formatted from large recordsets.
• Components in NLS.dll and Litware.dll describe the COM components built for the PT application. These components are built as generically as possible to maximize the ways in which you can reuse them.
