【摘要】 本文以键宽和键高查询为例子,以小见大阐述数据查询的实现。键宽键高查询以Delphi中的ADO组件连接加密的MS-ACCESS数据库实现。我希望通过本文企业和工厂中的机械设计人员由此掌握一种应用程序开发工具,从耗力耗时易错的手工查询摆脱出来,这对以后的工作和学习大有裨益。更多还原

【Abstract】 his paper expounds searching data with looking up key-width and key-height as example. Looking up key-width and key-height uses ADO component of Delphi link to encrypted database of MS-ACCESS. By this paper, I hope, grasping a programming language, mechanical designer quickly free from searching by hand waste-timely and hardworking, this will make great benefic to work and study.更多还原
