DLL技术在“大坝安全综合评价专家系统”开发中的应用

DLL and Its Application in the Development of a "Dam Safety Comprehensive Appraisal Expert System

探讨了 DLL技术及其在“大坝安全综合评价专家系统”开发中的应用 ;介绍了以 PowerBuilder作为主要开发工具 ,在其中调用 Fortran,C语言的 DLL方法 .该方法能合理使用多种程序设计语言 ,充分发挥各种语言的优势 ,从而提高开发效率及系统运行速度 ,避免重复编码 .

DLL and its application in the development of a 'Dam Safety Comprehensive Appraisal Expert System' is discussed, and the method of calling Fortran and C languages in PowerBuilder is described. The application of DLL makes it easier to use multifarious programming languages in the development of the Expert System, which produces higher development efficiency and faster speed of the Expert System by bringing the advantages of each programming language into full play.The application of DLL facilitates the reuse of the existing codes of a programming language so that repeated encoding is avoided.
