Software Development Based On COM Component

With the development of software architecture ,the creation of Standard component and the reuse of component becomes the key factor .Through reuse, we can make use of the production made before, and greatly speeds development of software .This paper introduces a method to implement common table component based on Visual C++/MFC. Whatever table in management software is required, we can use this method to make a complicated table into common table component, implement all kinds of table design. COM(Component Object Model)refers to a software framework regardless of the operating system and programming languages,which is produced by Microsoft Co.Characteristics of language independent,process transparent,software reused and more secure are fundamental of it. The aim of COM's programming is to divide the application into dependent models,which run at same machine or different machine,even different OS. As soon as requirement of application is changing,there is no necessity to modify whole application but models changed. It integrates function-software into applications by plug-and-in mode,which makes the software easy to design,upgrade and maintain. It reduces the cost spent on development and improve the efficiency of software development. The objective of this paper is to discuss the component methodology in the world of software engineering. First, I will present a summary of development background, the advantages and disadvantages of current methodologies. Then I will focus on some basic concepts and applications of COM. This paper introduce some concept about common control, and develop a complete example with Visual C++, Describing the method and process relating with development and use of common control. Through extensive research and discussion of the COM, I will come to the conclusion that the reusable ness is the key technique in component assembly, and that the COM is an effective methodology for development.
