摘要 随着计算机及网络技术的飞速发展和普及，分布式对象计算技术正成为计算机领域的研究、应用热点。构件技术减少了软件开发人员的重复劳动，以往的软件开发大都是从头开发编写，使用COM技术能通过构建一系列小的组件开发复杂的应用系统。 本文介绍的网络通讯平台MSNotice所采用的方案是当今比较流行的分布式组件对象模型（DCOM），使用开发工具Microsoft Visual C++ 6.0，数据库Microsoft Access 2000对通讯平台进行全面开发。本方案具有安全性强，通讯稳定，可扩展功能强大等特点。目前，此通讯平台的已开发的功能还很有限，数据的传输仅限于文本，但由于使用了组件进行开发，使得平台功能的可扩性大大增强了，根据用户的具体需求可以很容易地随时通过组件上留出的接口为平台添加各种所需要的功能。 本文采用了大量图片和文字对通讯平台进行详细的说明，对本通讯平台所涉及到的背景技术知识也做了大量详细的介绍，使文章更加通俗易懂。 关键词：计算机网络；COM；DCOM Abstract 　In recent years, global use of the network and computer become ever more　ubiquitous among the general population. The explosive growth of Internet and of distributed object computing general has led to significant technology　improvements in several domains Component significantly reduces the burden on application programmers by relieving them of this　kind of tedious and error-prone programming. Unlike traditional software development, which required each application to build from scratch.COM enables developers to create complex　applications using a series of small software object(COM component). The MSNotice that this article introduce adopt nowadays prevailing Distributed Component Object Model, using develop tools Microsoft Visual C++ 6.0 and database tools Microsoft Access 2000 to go on full development to the communication platform. This scheme can provide you the characteristic of strong security , steady communication ,powerful function expansion and so on. At present, the function development of this platform has been still very limited, the transmission of the data is only limited to the text, but using COM to develop make function expansion of the platform strengthen greatly, through the interfaces that reserve at the component we can easily add the functions of different needs for the platform very according to concrete demand of user at any time. To make the article more easy to understand, this article go on detailed comments with a large number of picture and characters to the communication platform, make
