Introduction

This book selects 100 representative programming examples in terms of controls developed using Delphi 6. These instances can be divided into windows and interfaces, graphic processing, multimedia, networks, databases and reports, systems, files, and other controls according to the completed functions, it covers the main aspects of Delphi 6 control application development. Among them, Delphi 6 comes with control instances and third-party control instances each account for half. This book emphasizes both basic and improvement, including basic knowledge, such as dynamic menu settings, mouse splitting interface, and Tree View display, as well as analysis of some advanced applications, such as 3D animation programs, TTS voice engines, and thin customer programs. By reading this book, you can understand and master common usage methods and advanced application skills in Delphi 6 control application development. Practicality is the biggest characteristic of this book. Most of the examples in this book have powerful functions, novel effects, and strong practicability. They can help readers quickly master the most advanced control application development technology, in addition, some examples focus on helping readers understand the basic concepts, key points, and difficulties of Delphi 6 control application development. This book is suitable for readers who have mastered the BASIC Programming Technology of Delphi 6.

Preface

Delphi has been continuously improved by Borland, a large number of third-party resources have been added, and a large number of fans have supported it, delphi has become a popular object-oriented programming language with powerful functions and a large number of users.

Delphi control technology combines visual C ++, Visual Basic, Power Builder, and other Windows development languages with excellent ActiveX control technology, at the same time, combined with the elastic reusable and complete object-oriented programming language (object-oriented language), a complete control recording solution is formed. In addition, the former is more integrated with excellent design ideas such as Delphi's excellent modular structure, making it very easy to expand from desktop applications to multi-layer, web applications, XML, at the same time, it shows fascinating potential in cross-platform use, mobile phone text messages, voice engines, and GIS global positioning applications.

This book provides a detailed description of the attributes, events, and methods of the 100 important controls, as well as in-depth discussions on key issues, so that readers can grasp the use of the controls as soon as possible.

The book is divided into six parts.

The first window and interface, describes how to use xpmenu, gifform, splitter, fctreecombo and other interface controls to create Windows XP interface, animation window, dynamic separation interface, and display Tree View in the drop-down list box.

Article 2 graphic processing describes how to use graphic controls such as drawgrid, dbchart, stringgrid, and layer to design applications such as graphics grids, database charts, block grids, and hierarchical graphs.

The third multimedia section describes how to use multimedia controls such as mediaplay, glvisir, ttsenglish, and abceffectsimage to design multimedia playback programs, 3D animation programs, TTS voice engines, and image special effect collections.

The fourth article describes how to use network controls such as nmftp, socket, webupdate, and geowhois to upload and download files, create popular software such as network communication and data transmission, online upgrade, and website locator.

Article 5 databases and reports, describes how to use database controls such as tclientdataset, tbatchmove, tdbctrlgrid, and wnquery to provide efficient database solutions such as thin customer programs, batch data operations, extended data grids, and universal queries.

Article 6 systems, files, and other controls, describes how to use skinengine, tsearchfolders, simplepie, printpreview, tamdesktop and other systems and file controls to write applications such as XP skin replacement, file scanning and searching, pie chart progress bar, print preview, and desktop background animation Effects program.

Each instance has three steps:

Instance effect: describes the functions of this example, and points out the design purpose and effect of this example, so that readers can have an intuitive understanding of this example.

Program description-explains the technical principles and design ideas of this example, and provides the basic process of program design, so that readers can quickly understand the program code: At the same time, describes the relevant knowledge involved in this example, in addition to learning the application of this instance, you can also learn about related concepts, function calls, parameter configurations, and other related knowledge, which is helpful for you to grasp how to use controls.

Production steps-specific implementation processes are provided, including the establishment of the form interface, source code and comments. You can refer to programming.

The related CD of this book contains all the examples of this book, all of which have been carefully debugged and can be directly called by readers.

The compilation of this book embodies the hard work and selfless dedication of a group of programmers and university teachers. Among them, Zhang Jingyu, He Wenjie, teachers from Shandong University, such as Liang leiqing and Xiao renhua, have contributed and carefully revised many excellent original codes, translated some foreign codes, and debugged them one by one. Professor Duan Xin of Shandong Education Commission took time out of his busy schedule to review and debug the key chapters and codes in this book. It is their outstanding talent and good team spirit that make this book further develop in terms of quality. Thank you.

This book is planned by Qingdao delta digital technology development center and edited by Duan Xing.

Due to the limited level and the rush of time, this book will inevitably have shortcomings, and we hope that readers will criticize and correct it.

How to Use the CD in this book:

The related CD of this book contains the source code of the book's 100 instances and most of the corresponding third-party controls. The instance source code is located in the root directory of each instance on the CD, or in the "demos" folder under the root directory of each instance on the CD, the corresponding third-party control is located in the "sourse" folder or "components" folder under the root directory of the CD instance.

When you use the source code of a CD-ROM instance in this book, instances involving third-party controls need to be re-installed and registered. For some instances involving databases, you need to re-set the database alias for the folder where the database is located, for example, "mydatabase". In addition, some remote access instances need to set more parameters for normal operation. For specific database alias and other parameter settings of each instance, see the example program description and production steps.

The vast majority of the third-party free controls involved are contained in the corresponding instance folders on the CD. The third-party sharing and commercial controls involved are described in the "program description. All used database files are stored in the "Database" folder under the root directory of the disc. Please relocate the source code settings based on the local settings.
