vb通讯《GIS开发者》Visual Basic 是Mcrosoft公司推出的强有力的系列开发软件之一，而且以其实用、方便、快捷、开发周期短、广泛而强大的功能越来越被广大编程人员所亲赖，广为流传，似乎有些专业的编程人员放弃了Visaul C++ 而改用了Visaul Basic之类的RAD编程工具，尽管Visaul C++在灵活性、代码紧凑、运行速度快及底层开发等方面Visaul Basic无法比拟的，但编写C++应用程序过长的调试和开发周期确实有点不适应当今的应用程序开发环境。-vb communications, "GIS" Visual Basic is Mcrosoft launched a series of powerful software development, but its practical, convenient, fast and short development cycle, extensive and powerful features are increasingly the majority of programmers are pro-Lai, the most widely circulated, it appears that some professional programmers abandoned FoxPro C and switch to the Basic FoxPro like RAD programming tools, despite the flexibility of C FoxPro, code compact, fast operation and development, and so on the bottom FoxPro Basic incomparable, but the C application debugging and long development cycle is really not suited to today the application development environment.
