Component GIS (ComGIS), a new technology based on COM(Component Object Model),is currently a main means in GIStechnology. Recently, this technology has developed so fast that more and more ComGISsoftwares are available in the market. This paper gives a detailed review of ESRI's MapObjects. MapObjects is flexible and open, but can not be symbolized. This paper deals with the technique for symbolization by using Visual C++ and the ComGISsoftware. It is believed that ComGISwill grow into an important branch of Earth System Science. MapObjects is surely to be used widely, and can play an important role in Geographic Information Systems. This study helps to understand the development of core GIS's function by using VCcombined with ComGIS.
