摘要
本文介绍了在VB6.0中访问MapInfoProfessional5.0的OLE方法,详细地探讨了OLE回调技术在VB与MapInfo集成地图开发中的应用.同时使用多种语言进行混合编程,充分利用MapInfo对地理图形对象的管理和操作功能及VB的数据库管理完善、界面设计灵活的优点,使程序的整体性能得到了提高,节约了开发人员的时间和精力,取得了较为满意的效果.
In this paper, the authors introduce the OLE methods to access MapInfo Professional 5.0 in VB 6.0 simply, and focus on the application of OLE callbacks in integrated mapping development with VB and MapInfo. Mixed programming between VB, MapInfo and MapBasic is adopted. The advantages of MapInfo in managing and operating geography object and the advantages of VB in database management and flexible interface design method are fully made. The programming method not only enables the application to improve its efficiency but also saves the programmer's time and energy.
