VC与Delphi及C++之间的比较

由于Delphi与C Builder同为Inprise公司产品，共享集成开发界面(IDE)，而且使用同一套VCL框架，它们带的调试器、PVCS／TeamSource团队开发支持、数据库引擎及企业版中集成的其他高级功能等都是相同的，所以本文将其与C Builder归入“同一阵线”。我在网上见到一些Delphi程序员认为     

利用Tree View组件显示复杂数据结构

本文详细阐述了如何利用Delphi提供了Tree Vlew组件实现程序运动过程中产生的树结构的可视化的问题。本文讨论了内容主要用于应用程序使用前的调试，它使得比较复杂的数据结构对程序员变得透明，可以极大地提高调试速度。     

在Delphi环境c／s模式下的ADO／BDE使用探讨

近年来，利用计算机和数据库技术来辅助管理运作变得越来越为普遍。在这种情况下。数据库程序开发及数据库技术越来越重要。而Delphi一直以其强大易用的特点得到程序员的青睐。Delphi7．0除保留了以前版本的强大功能之外，更在数据库程序开发方面提供了强有力的支持，使程序员完全可轻松开发出复杂且功能强大的数据库应用程序。本文从Delphi提供的数据库的两种访问方法，ADO与BDE方法。并简要介绍在C／S模式下的两种访问方法的使用。

Delphi6.0的消息处理机制及应用

阐述了在Delphi6 .0中VCL构件的消息处理机制和消息处理过程 ,介绍了在两应用程序间进行消息传递的程序段 .     

C++Builder中自主处理事件的实现

C Builder是目前比较优秀的C 编译器，其推出的可视组件库(VCL)具有可视性好、使用方便的特点。该库包含了Windows中常用的部件，C Builder将事件的处理封装在类中，程序员不必自己处理事件，但有时我们也需要直接处理事件即自主处理事件，为此，本文给出了C Builder中自主处理事件的原理和方法。     

DELPHI中自定义组件的制作方法介绍

组件是Delphi编程的核心,掌握自定义组件的编写方法,对于提高编程人员的编程能力是特别重要的一个方面,本文介绍了在Delphi中自定义组件的一般步骤,在每个步骤中的技巧和注意事项.对Delphi编程人员具有启发和指导作用.     

Delphi中数据文件路径的管理

Delphi以其独特的面向控件的开发方式、强大的数据库功能以及快速的编译术，使得它自发布起即格外引人注意。随着Delphi7提供丰富的Internet应用，Delphi日益成为最重要的软件开发工具之一，而Delphi程序的开发和使用中有很多的数据文件。不同的程序员会根据不同的爱好把所用的数据文件存放到不同的地方，但这些数据文件是每个程序员都要用到的，因而数据文件路径的管理已是广大Delphi程序设计者急需解决的问题。     

DELPHI自定义构件中的消息处理

本文就Delphi 4.0中VCL构件的消息处理机制、在定制构件中自定义消息及消息处理句柄时应遵循的原则及消息过滤的方法等问题进行了简要探讨.     

ListView控件中列标头点击排序功能的实现

C Builder 是目前比较优秀的C 编译器,其推出的可视组件库(VCL)库提供了程序设计中常用的列表框控件ListView,但该控件不能实现排序功能.而排序功能在编程过程中经常使用,为此,本文给出了在C Builder中ListView控件列标头点击排序功能实现的原理和方法.

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
