用类实现一个应用处理多种文档

介绍了如何用ＶｉｓｕａｌＣ＋＋语言的一个Ｗｉｎｄｏｗｓ和ＭＦＣ的应用程序中同时处理两种类型以上的文件。例如在一个报表制作程序中，既要处理存贮报表格式和内容的数据文件，又要处理对数据进行运算的命令文件。这两个窗口不论是外部表现还是内部处理机制都是完全不同的。ＭＦＣ对Ｗｉｎｄｏｗｓ函数的封装和模块化的程度很高，实现时遇到了麻烦，在此通过实验获得的解决这一问题的一些经验，供读者参考。

Dealing with Application Documents of Multiple Kinds by MFC

This article introduces the way how to deal with documents of multiple kinds in Windows and MFC (Microsoft Foundation Class) based on application programs using the Visual C language.In a report generation program,for instance,both data documents storing the format and contents of the report and command documents that the data are operated by are to be processed.However,the two windows concerned are completely different from each other in external performance and internal mechanism.It is therefor quite troublesome to fulfill this task as MFC seals up many windows functions and is highly modularized.Some experience obtained through experiments to solve this problem is given herein for readers' reference.
