Introduction

As a new version of Delphi, Delphi 6 not only helps programmers efficiently develop Windows applications, but also simplifies the synthesis of Web Services, intermediate software, and background database systems, it is the only tool that fully supports all mainstream industry-standard development tools and enhances e-commerce capabilities. This book is rich and clear, and describes the essence of Delphi 6 in a simple language. It has great reference value for Delphi or programmers who are about to transplant it to Delphi. At the end of this book, I also introduced the application of Delphi in the Internet. Today, mobile commerce network programming is becoming increasingly popular and will undoubtedly become the focus of attention of programmers.
