基于COM技術的公式計算組件的開發(fā)與實現(xiàn)
畢業(yè)論文
摘要
目前,在計算機軟件工程中,組件化程序設計思想迅速發(fā)展起來。為此微軟提出了COM (Component Object Model,組件對象模 型)標準。COM是組件對象之間相互接口的規(guī)范,凡是遵循COM接口規(guī)范的對象彼此之間能相互通信和交互 。COM是1種與操作系統(tǒng)和編程語言無關的軟件架構,它將功能軟件以即插即用的方式集成到應用中,便于軟件系統(tǒng)的設計、升級和維護,降低成本 提高效率。
本文介紹了COM的內(nèi)存結構、實現(xiàn)原理、分類和特性,包括 COM對象和接口、IUnknown接口、COM對象的創(chuàng)建、組件與客戶之間的通訊,分析了公式計算模塊的特點,設計和實現(xiàn)了基于COM的公式計算組件。該組件能提供基本的數(shù)學公式計算。最后用MFC設計了1個驗證該組件的仿真。通本本論文可以看到開發(fā)COM組件的流程。

Abstract
In the computer software engineering the idea of the modularization programming design is developing rapidly. The Microsoft presents the COM (Component Object Mode1) standard. The COM is the interface specification of the components. All components complied with the COM interface specification can communicate with each other. COM refers to a software framework regardless of the operating system and programming languages.It integrates function-software into applications by plug-and-in mode, which makes the software easy to design, upgrade and maintain.Thus the cost is lowered and the efficiency is raised.
This tohttps://p.9136.com/28’s structure, implementation,classes and characteristic, including COM object and interface and interface, IUnknown interface, building of COM object,and communication between component and its caller, introduces the design and implantation for the formula calculating component based on COM by analyzing the characteristics of the formula calculating module. The component can provide the function of calculating basic math formula. In the end, this topic introduces the implantation of a simulation which is to check the component by using MFC. Through this paper, we can see program flow of COM component.
Key words: component; COM; Interface; formula calculating.
