Introduction

Internet technology is undoubtedly the biggest hotspot in today's computer technology. This book uses the latest version of Delphi, one of the most popular rad software, as a development tool. It tries its best to include popular protocols on the Internet, describes the development principles of network applications and how to implement them on the Windows platform. This book focuses on programming instances, supplemented by necessary technical points, and introduces in detail various aspects of network programming, covering most of the protocols used in network communication, including online chat, obtaining network parameters, sending and receiving emails, ping, FIP client, web server and browser, telnet server and client, rib s dial-up Internet access, and TAPI programming. This book is suitable for medium and senior programmers who use Delphi for Windows Network Programming. Of course, beginners can also benefit from this.
