基于动态数据交换的应用程序设计技术

The Application Programming Techniques Based on the DDE Method

ＭｉｃｒｏｓｏｆｔＷｉｎｄｏｗｓ提供了几种在应用程序之间交换数据的方法，其中之一就是使用Ｗｉｎｄｏｗｓ的动态数据交换（ＤＤＥ）．ＤＤＥ是Ｗｉｎｄｏｗｓ的程序之间进行数据交换的一个消息协议，它允许软件开发人员在应用程序之间共享数据，从而为用户提供了更为集中的Ｗｉｎｄｏｗｓ环境。作者将从ＤＤＥ方法、对象链接与嵌入（ＯＬＥ）。

DDE is one of the methods provided by microsoft windows, which can be effectively used in data exchanging between application programs. It is a message protocol of data exchanging in windows applications, which enables program developers to share data between them.As a result, the user gets a more integrated windows environment. In this paper we'll introduce the DDE method, OLE, client/server devices as well as the implemetation of the DDE based application programming.
