Features: This book is a higher vocational and community college planning teaching material published by the Ministry of Education, written according to the new Basic Requirements for Teaching of Structured Programming Courses in Higher Vocational and Community Colleges issued by the Ministry of Education. Visual Basic for Chinese Edition is a simple and easy-to-learn application software development tool newly released by Microsoft. It is powerful, versatile, and has been well-received by computer users, gaining widespread application. This book introduces the basic concepts and usage of Visual Basic for beginners, focusing on file operations, OLE technology, ActiveX controls, databases, and DHTML programming techniques for the main application areas of Visual Basic. The content is arranged from simple to complex, emphasizing both typicality and practicality. To meet teaching needs, each chapter highlights key points and difficulties, explains them with examples, and includes a certain amount of hands-on exercises. The book has the following features in its writing:
1. As a programming language textbook, the structure of the book has been carefully considered. Basic concepts and difficulties are distributed, and the writing progresses step by step from simple to complex. The examples chosen are representative, demonstrable, and coherent. Each chapter emphasizes key points and difficulties to facilitate student learning and review.
2. Language learning is largely mastered through hands-on exercises and practical operations, so improving the efficiency of hands-on exercises is a key consideration in the book's writing. Each basic statement, function, and concept is explained with short programs, and each chapter weaves together the learned content to create complete programs. Hands-on exercises include mandatory and optional tasks, with repeated practice of learned material to aid memorization; representative functional applications for deeper language understanding; and comprehensive concepts that integrate window, object, event, property, and method concepts to ultimately cultivate a holistic understanding and achieve better results.
3. When learning any language for the first time, it may seem relatively easy, but further study reveals many concepts and difficulties, which is a common experience for learners. Based on this, the book does not aim to cover every aspect of Visual Basic 6.0, but instead focuses on the most common and practical programming techniques, striving to explain them clearly and thoroughly without ambiguity. This way, students gain the ability to further their learning once they have acquired basic programming skills.
4. In terms of content arrangement, the first four chapters introduce the development environment and basic knowledge of Visual Basic 6.0 to help beginners get started, primarily focusing on the basic methods and steps of visual window programming. Chapter 5 covers file processing and applications, as well as the relevant controls used in file operations. Chapter 6 introduces some concepts of object-oriented design and methods for implementing OLE technology to help students understand the practical aspects of object-oriented design. Chapter 7 discusses some application methods of ActiveX controls, using several representative controls to illustrate their usage. Chapter 8 covers the main techniques of database management in Visual Basic, including the concepts of DAO, RDO, and ADO, as well as SQL methods for database processing. Chapter 9 introduces DHTML design, primarily explaining how to use Visual
