Delphi、MapInfo集成开发环境下CallBack的实现

Realization of CallBack Under Delphi & MapInfo Integrated Developping Environment

在客户程序中集成MapInfo后,客户程序可以向MapInfo发送各种指令,执行各种操作。但作为服务器的MapInfo一般不会主动向客户程序发送信息,是较为被动的角色。这里介绍了如何让客户应用程序接收MapInfo发送的消息,并进行相应处理的有效方法。

Client program can send all kinds of instructions to MapInfo, and excute all kinds of operations after it has integrated with MapInfo. As a server, MapInfo acts as a relatively passive role, and never sends messages to client program forwardly. This article introduces a way of how client program could receive messages from MapInfo, and how to process these messages efficiently.
