About this book

Audience

You should read this book if you are involved in any phase of a client/server, distributed, or Web application development project that uses PowerBuilder®.

How to use this book

This how-to book guides you through programming techniques used to build and deploy PowerBuilder applications and components. It does this by equipping you with collections of techniques for implementing many common application features and advice for choosing those techniques best suited to your requirements.

PowerBuilder is accompanied by sample applications that illustrate some of the issues, features, and techniques you will read about. Examine the components of these applications in PowerBuilder, read the comments in the code, and experiment with real, working examples of what you are trying to learn.

For where to find the sample applications, see Chapter 1, “Using Sample Applications.”
