摘　　要：Windows应用程序接口API(ApplicationProgrammingInterface)是可视化编程工具的扩展和延伸,他提供了大量的应用程序接口可供VisualBasic直接调用。本文介绍了如何使用Windows中API函数BitBlt实现VisualBasic的图像切换的特殊方法。使用BitBlt可直接对显示缓存的图像进行处理,他不但扩展了VB的图像处理功能,同时也提高了程序的执行效率。The API, an application program unit of Windows is an expansion and extension of the visualized programming tool. It provides many application program units that can be directly used with Visual Basic. This paper introduces a special approach of how to achieve image alternation with Visual Basic through the application of BitBlt, an API function in Windows. The application of BitBlt in the processing of patterns can not only expand the capability of VB pattern processing,but also enhance the operating efficiency of programs.
