Introduction

This book describes how to use Delphi 6 to develop applications. After briefly introducing the basic knowledge of Delphi, this book describes in detail the advanced features and new features of Delphi 6, and provides a large number of examples for reference.
The book is divided into 19 chapters. 1 ~ Chapter 8 introduces basic knowledge of Delphi and advanced object-oriented programming. 9 ~ Chapter 12 discusses the knowledge about component programming. 13 ~ Chapter 14 describes some database-related components. 15 ~ Chapter 19 is some of the more advanced content, including the content of the middleware, Web broker, network programming, Windows programming, and SQL programming.

This book is suitable for middle and senior programmers, and can also be used by programmers who migrate from other programming tools to Delphi.
