MFC (MicroSoft Foundation Class Library)中的各種類(lèi)結(jié)合起來(lái)構(gòu)成了一個(gè)應(yīng)用程序框架，它的目的就是讓程序員在此基礎(chǔ)上來(lái)建立Windows下的應(yīng)用程序，這是一種相對(duì)SDK來(lái)說(shuō)更為簡(jiǎn)單的方法。因?yàn)榭傮w上，MFC框架定義了應(yīng)用程序的輪廓，并提供了用戶接口的標(biāo)準(zhǔn)實(shí)現(xiàn)方法，程序員所要做的就是通過(guò)預(yù)定義的接口把具體應(yīng)用程序特有的東西填入這個(gè)輪廓。MicroSoft Visual C++提供了相應(yīng)的工具來(lái)完成這個(gè)工作：AppWizard可以用來(lái)生成初步的框架文件（代碼和資源等）；資源編輯器用于幫助直觀地設(shè)計(jì)用戶接口；ClassWizard用來(lái)協(xié)助添加代碼到框架文件；最后，編譯，則通過(guò)類(lèi)庫(kù)實(shí)現(xiàn)了應(yīng)用程序特定的邏輯。
The 6.0 release of Visual C++ shows MicroSoft s continued focus on Internet technologies and COM, which are key components of the new Windows Distributed interNet Application Architecture (DNA). In addition to supporting these platform initiatives, Visual C++ 6.0 also adds an amazing number of productivity-boosting features such as Edit And Continue, IntelliSense, AutoComplete, and code tips. These features take Visual C++ to a new level. We have tried to make sure that this book keeps you up to speed on the latest technologies being introduced into Visual C++.
NewMail 對(duì)象不是建立在普通的 API 體系結(jié)構(gòu)上。它被 MicroSoft? Windows NT? Server 中運(yùn)行的自動(dòng)進(jìn)程用于快速產(chǎn)生通告郵件。它不提供任何用戶接口，在郵件的產(chǎn)生和發(fā)送過(guò)程中也不提供任何的交互。因此 NewMail 對(duì)象的屬性沒(méi)有被設(shè)計(jì)成為可以回讀和檢查。僅除 Version 外，其他屬性只能被寫(xiě)入。
