Introduction

This book compiles 60 typical ones in Delphi, including 8 parts, that is, basic knowledge, graphic country image file system and rave reports, development of database applications, establishment of cross-platform applications, establishment of XML applications, advanced applications, development of game applications, and integrated applications. Each instance is explained in detail in terms of instance description, core technologies and techniques, implementation steps, running results, and main code, this allows the reader to master the key technologies and methods for developing every example, thus greatly improving the level of development of various applications using Delphi. The content of this book is from simple to deep, step by step, so it is suitable for beginners, but also for medium and senior readers. It can also be used as a reference material for colleges and training courses or books for computer exercises.

Preface

Borland (now changed to Inprise) has always been known for its easy-to-use development tools. Borland C was released in the early 1990s s with 10 dozen languages, once formed a tornado sweeping the world's entire IT industry, its easy-to-use interface, convenient and flexible development language, fast and efficient compiler, it has created an unprecedented new situation for the development of various applications. It is also a development tool that many old programmers once love. The Delphi language is the fourth generation language developed on the basis of Borland C's 10 dozen languages. It has rich and powerful components, you can simply drag a few mouse clicks to design the basic interface of an application. Therefore, although this language is later than VB, Vc, and other languages, it has been favored by many programmers since its launch. It has been set by many software development companies and scientific and technological institutions as the preferred software development language. Especially with the release of Delphi 7, its functions have been further improved. It can be used to develop various types of applications, such as database applications and network applications, both general applications and complex multi-level applications can be developed with Delphi 7. This book is an example of the essence of the book, the author in this form to describe the various functions of Delphi, because of years of development experience and communication with other programmers tell us: the fastest and most labor-saving way to learn a language is to study existing examples, because these examples can not only grasp the basic structure of the language to develop applications, in addition, you can gain an in-depth understanding of all its functions, so that you can quickly get started with writing code that meets your requirements. The content of this book is from a simple perspective, step by step. The Implementation ideas and development skills of each example are thoroughly analyzed and thoroughly explained, so that readers can quickly master the core technologies included in this example, and can deeply understand the methods for developing the same type of applications to avoid detours. This book is written by Zhang haiqing and Zhang zhanjun of second-built Yantai. In addition, the authors of this book are Li Jin, Wang Haifeng, du Zhiyin, Liu Liping, Wu Jing, huoping, Song Qinghai, Xia Kun, Ding Jiang, Yan Li, Zhou ting, Su Limin, and Dong Leng. guo Bin, Li Jin, Hong Zhuan, Zhang Ling, Jiang Ming, Gu foreground, Qian Daou, Wu Qinggong, Sun Dehong, Li Bing, che Linlin, Zhang Yingchun, Mingzhi city, Deng min, Xu ding li Gang, Sun Xun, Xia Li, and other comrades, I would like to express my gratitude for this. Of course, although the author has carefully compiled and modified every example, due to limited personal abilities, mistakes and mistakes may inevitably exist. I hope you will criticize and correct them. The author's e-mail: sdzlqsdzlq@sohu.com. Prepared
