初學DelphiI的人,由於各種原因,對DelphiI中的許多概念不能很好的理解,並由此帶來了許多的問題,或者是開發出的程式穩性不好,一會能運行,一會又不能運行;或者是遇到一個問題久思不得其解,還誤以為是DelphiI自身的BUG,等等這些,浪費了我們大量的時間、精力,也影響了我們的開發效率。那麼如何才能避免這些錯誤了,盡量少走彎路了?筆者從事DelphiI開發多年,下面就把我的經驗總結介紹給大家,希望協助到初學DelphiI的朋友。問題一:對類的概念理解不到位,程式開發中不能靈活運用。請看下面

怎樣在DELPHI中實現檔案切割/組合

wf架構編程-基礎部分

1編程模型從消化系統講起,口腔、腸道、胃…等消化器官組成了消化系統,每個器官又是由更微觀的物質構成,比如細胞。細胞又可以細分。細胞可以分類,白細胞,紅細胞等等。這裡細胞可以認為是消化系統的基本組成元素。這種組成結構非常像物件導向的思維,因為它們都要解決同一個問題:現實世界複雜性。類可以認為是最基本的組成元素,類可以組成組件(構件) ,構件組成服務。知道了消化系統的組成,我們來看如何?吃這個功能,吃的功能完成需要食物通過各種消化器官,使用消化器官的功能完成。這個過程是面向過程的,是一
