摘　　要：在MIS应用中,通常要对用户权限进行控制。文章既分析了两种常用的用户权限控制方法的缺陷,也提出了一种基于系统菜单项的用户权限控制的方法,并用PB实现了获取系统菜单项的算法,同时结合实例用PB设计了一个通用的系统用户权限设置窗口,以实现菜单项的用户权限管理,并该方法具有很好的通用性和实用性。In MIS Systems, user permissions generally should be controlled. This paper analyzes the shortcomings of the tow kinds of user permission control methods generally used and then brings forward a method of control user permissions by system menu items, making possible the recursive algorithm of visit system menu items in PowerBuilder. The paper provides the method of user permission control with menu items in an application using PowerBuilder, and it is universal and practical.
