摘　　要：本文主要研究了基于MapX组件的地理信息系统的二次开发。由于MapX本身存在的某些缺陷,不能够以中文字段值作为专题字段生成专题的问题与不支持多字段同时标注的问题,提出了采用构建离线ADO重新绑定MapX的Layer对象的方法和利用MapX的Annotation对象动态生成标注的方法来解决这两类问题,并在陕西师范大学公用房管理系统中成功地进行了实现。This thesis mainly researches the problems of building thematic map and labeling with many fields in the process of the secondary developing of GIS application software on the base of MapX. This thesis mainly studies the problems that in the process of the secondary development of GIS based on the component of MapX, due to MapX certain inherent defects, the Chinese field can not be as a special field to generate thematic map and it do not support multi-field labeling at the same time.It focused on the method of the rebinding building offline ADO and the Layer of MapX,and using the Annotation of MapX to dynamically generate labels in order to solving these problems.Additionally,This thesis successfully implements them in the developing of the manage-ment system of the common room of Shaanxi Normal University.
