vb是Visual Basic的简称，是由美国微软公司于1991年开发的一种可视化的、面向对象和采用事件驱动方式的结构化高级程序设计语言，可用于开发 Windows 环境下的各类应用程序。它简单易学、效率高，且功能强大可以与 Windows 专业开发工具SDK相媲美。在Visual Basic环境下，利用事件驱动的编程机制、新颖易用的可视化设计工具，使用Windows内部的广泛应用程序接口（API）函数，动态链接库（DLL）、对象的链接与嵌入（OLE）、开放式数据连接（ODBC）等技术，可以高效、快速地开发Windows环境下功能强大、图形界面丰富的应用软件系统。-Vb is Visual Basic abbreviation, is from the Microsoft in 1991 and development of a visualization, object-oriented and adopting event-driven way of structured high-level programming language, can be used to develop Windows environment of all kinds of applications. It is easy to operate, high efficiency, and powerful professional development tools can with Windows SDK comparable. In the Visual Basic environment, use event-driven programming mechanism, novel easy-to-use visualization design tool, using Windows internal widely application program interface (API) function, DLL are stated, object links with embedded (OLE), open data connection (ODBC) technology, can efficiently and quickly develop Windows environment powerful functions, graphical interface rich application software system.
