Abstract: The management of user authority is one of the basic and important functions of a system. Firstly, the frequently used methods of control user authorities and their characteristics are explored. Secondly, a general user authority management method based on menu items is proposed, and then the design of the tables, the design and implementation of the menu item traversal class, and the design and implementation of a window using a tree-view to set role permissions are given. Finally, the application of this method in an open computer-room management system is introduced.

Key words: menu item traversal, role permission, user permission, generic queue
