| 摘 要： | Microsoft.NET是微软公司推出的新平台,具有强大的全方位技术兼容性。另外,目前基于微软平台的软件通信几乎都是COM实现的,而MapInfo软件是应用广泛的主流GIS软件之一。本文主要结合COM和MapInfo实现GIS的应用开发,即利用.NET的COM组件封装技术实现MapInfo相关接口的打包封装,之后利用.NET的COM回调机制——实现更具简便性与灵活性的GIS应用。本文详细探讨了该机制在实现MapInfo二次开发中的具体思路及关键技术点,取得了较为满意的应用效果。

| Abstract: | Microsoft. NET, a new platform of the Microsoft, which has an excellent power of technique compatibility. COM is the advanced technology of Microsoft, and it accomplishes almost all the communication between components of different softwares. MapInfo is one of the main software of GIS which is used broadly. The GIS applications based on COM and Maplnfo is introduced in this article. That is, based on COM component packing technology of. NET, the interfaces of MapInfo were packed. With callback mechanism of the packed COM, it can be more simple and flexible to explore the GIS applications. This article presented a dee Pdiscussion on the thoughts and technologies of secondary development of MapInfo using callback mechanism, and got a satisfaction with its application. |
