说明：  Visual Basic是一个Windows系统下流行的应用程序开发平台。其方便的界面设计使程序员能节省大量时间，并把最大的精力集中在应用程序核心代码的编写上。VB4目前已成为Win95系统下一种最高效灵活的主流开发工具之一，而调用API应用程序接口则正是对VB4功能的强有力扩充，它使得VB4能够直接控制和处理PC硬件资源，而不必依赖于MS-DOS系统服务。可以说，正是借助于API使得VB即能隐藏大部分Windows编程的难点，同时又提供了使用Windows环境的灵活性。
(Visual Basic is a popular Windows application development platform. Its convenient interface design enables programmers can save a lot of time, and the greatest focus on the core application code on the preparation. VB4 Win95 has become the current system one of the most efficient and flexible mainstream development tools, and the one calling API Application Programming Interface is precisely the function of VB4 strong expansion, it makes VB4 to directly control and manage PC hardware resources, without having to rely on MS-DOS system services. It said that it is made using VB API that can hide the most difficult Windows programming, while providing a Windows environment flexibility.)
