"Easy Language" realizes real Chinese programming, completely gets rid of the language barriers and thinking barriers existing in the use of traditional English programming tools, and writes real "Made in China" programs in a way that is more in line with Chinese habits. Developing programming no longer needs to memorize complicated English commands and words, as long as you can input Chinese characters or pinyin, you can develop specialized programs. "Easy Language" has a built-in desktop database, supports a variety of large databases, and can realize network and hardware communication programming. The object-oriented programming concept, rich interface elements, thousands of system commands, APIs, and COM support of "Easy Language" are enough to meet the development requirements of different application levels in various industries. "Easy Language" will be an ideal programming tool for the majority of computer users. The book consists of 30 chapters and 3 appendices. The main contents include: Easy language overview, data types, variables, constants, resources, commands, process control commands, subprograms, window components, multimedia, network and communication, system control, easy database, easy database, API call, easy module, DLL writing and calling, OCX component and type library, COM object, object-oriented programming, Linux program writing, data structure support library, data operation support library, text-to-speech conversion support library, telephone voice support library, digital device support library , scripting language support library, office support library, as well as program debugging, compilation and publishing, easy wizard use, etc. The content of this book is easy to understand, rich and informative, with pictures and texts, and simple and practical programming skills. It is suitable for beginner and intermediate programming users, and can also be used as a reference book for teaching, self-study and social training courses in colleges and universities. The accompanying CD includes the source code of examples of various chapters in the book, the source code of hundreds of open source programs, comprehensive teaching animation demonstrations, online download URLs and other related resources, and provides the latest version of the "Easy Language" software. Readers should raise technical questions in the process of using this book on the Yiyu website or the technical exchange forum on it.
