文字是信息处理的基本单位，许多计算机软件系统都需要对一定的文字进行编辑处理，这种编辑处理的形式一般都包括打开、存储、显示、修改、文字查询等等，这些功能如果要让程序员通过底层编程逐条实现，既耗费时间又耗费精力，令人欣慰的是，目前各类版本的C++语言一般都提供基本的文字处理类供用户使用，拿当今最为流行的Visual C++语言来说，它提供了CEditView类，此类封装了对文字的多种操作。笔者在多媒体图文声像数据库系统的编制过程中通过继承此类实现了对文字数据的各种处理，效果良好。 -Text is the basic unit of information processing, computer software systems need to edit some text processing, the form of this editing process is generally open, storage, display, modify text query, if you want these featuresmembers of the underlying programming one by one to achieve both cost time and consuming energy, reassuring is, all kinds of versions of the C++ language generally have to provide basic word processing class for the user to use, today s most popular Visual C++ language, for instance,it provides a CEditView class, which encapsulates the operation of a variety of text. Author through inheritance in multimedia graphic audio-visual database system preparation process such text data processing, to good effect.
