1、毕业论文（设计）外文资料及译文题 目：选修课网络查询系统的开发学 生 姓 名：指 导 教 师：系 别：信息技术系专业 、班级： 完 成 时 间：Visual Basic programming language 1991, the United States launched the Microsoft Visual Basic (may be referred to VB), is the latest version of the current VB 2008 Beta2 (VB9) Chinese version. Visual meaning the visual, visible,

2、 referring to the development of operating systems like windows graphical user interface (Graphic User Interface, GUI) method, it does not need to prepare a large number code to describe the appearance of the interface elements and location, as long as the pre - The establishment of good drag and dr

3、op objects on the screen corresponding to the location. Basic is actually an abbreviation of the phrase, this phrase is Beginners all_purpose symbolic instruction code, the Chinese meaning to the initial directive GM symbol code language. Visual Basic learning, Professional Edition and Enterprise Ed

4、ition versions to meet the different needs of the development. Study and apply to the ordinary version of the majority of learners and the use of Visual Basic development of the general staff of Windows applications, but; professional version for computer professional development of staff, including

5、 the study of functional version of the full content control and Internet development tools such as advanced features ; Enterprise contain not only all the professional version of the content, there are automated tools such as Component Manager, professional programmers to make the development of a

6、powerful group essence of distributed applications. VB is a visual, object-oriented event-driven approach and the use of the structure of high-level programming language, can be used for the development of the Windows environment of various applications. It easy to learn, efficient and powerful with

7、 Windowsr professional development tools comparable to SDK. In Visual Basic environment, the use of event-driven programming mechanism, the new easy-to-use visual design tools, within the wider use Windows application program interface (API) function, to use dynamic link library (DLL), the object Li

8、nks embedded with the World at (OLE), open-end data connectivity (ODBC), and other technology, can be highly efficient and rapid development of the Windows environment powerful, rich graphical interface application software system. With the improved version, Visual Basic functions also growing. Afte

9、r version 5.0, Visual Basic launched a Chinese version, compared with the previous version, its functions have been greatly improve. However, more powerful functions, Visual Basic still has one drawback: in the absence of MSVBVM *. DLL must be installed on the computer the required DLL file. It can

10、be designed with the operating system, but more difficult. In the early 21st century, microsoft has introduced Visual Studio 2003 and Visual Basic among the significant changes, Visual Studio for a variety of programming tools to a platform, Visual Basic.NET can run on this platform. Compared with t

11、raditional VB, are quite different. VB.Net, used for the first time. Net framework for visual programming, and can a good framework compatible with COM. 2005 Visual Studio 2005则use of the NET 2.0 technology, more convenience to the programmers work. But the new procedures on the system configuration

12、 requirements are also higher, the need for Microsoft. Net Framework 2.0 above. Net framework support. December 2007, Microsoft (Microsoft) launched the Visual Studio 2008 Beta 2 has undergone major changes (see attached map) enter in the code when the VB2005 can be much faster than in non-exception

13、al circumstances, VB2008 will automatically open automatically Keyword completion of this order and begun to support the latest. NET Framework 3.5 Beta 2 The role of programming tools has evolved over the past 45 years along with computer hardware. A programming language today, such as Visual Basic,

14、 differs greatly from programming languages of just a few years ago. The visual nature of the Windows operating system requires more advanced tools than were available a few years ago. Before windowed environments, a programming language was a simple text-based tool with which you wrote programs. To

15、day you need much more than just a language; you need a graphical development tool that can work inside the Windows system and create applications that take advantage of all the graphical, multimedia, online, and multiprocessed activities that Windows offers. Visual Basic is such a tool. More than a

16、 language, Visual Basic lets you generate applications that interact with every aspect of todays Windows operating systems. Visual Basic 5 comes in three flavors: the Standard Edition, the Professional Edition, and the Enterprise Edition. Although this book primarily deals with the Professional Edit

17、ion, the Standard Edition is called the learning edition and provides the least expensive approach to using Visual Basic. The Standard Edition gives you a complete development environment, programming language, and many of the same tools the other editions offer. If you use the Standard Edition, you

18、 have a powerful programming tool. Some people develop only with the Standard Edition and never need anything else. Although this course targets the Professional Edition in an attempt to hit common ground, you will be able to utilize virtually the entire 24-hour course if you use the Standard Editio

19、n; you will find additional tools in the Standard Edition that this course does not even get to.Visual Basic编程语言 1991年，美国微软公司推出了Visual Basic(可简称VB），目前的最新版本是VB 2008 Beta2(VB9)中文版。 Visual 意即可视的、可见的，指的是开发像windows操作系统的图形用户界面（Graphic User Interface,GUI）的方法，它不需要编写大量代码去描述界面元素的外观和位置，只要把预先建立好的对象拖放到屏幕上相应的位置即可

20、。 Basic 实际上是一个短语的缩写，这个短语就是 Beginners all_purpose symbolic instruction code ，其中文意思为“初始者通用符号指令代码语言”。 Visual Basic有学习版、专业版和企业版三种版本，以满足不同的开发需要。学习版适用于普通学习者及大多数使用Visual Basic开发一般Windows应用程序的人员，但是；专业版适用于计算机专业开发人员，包括了学习版的全部内容功能以及Internet控件开发工具之类的高级特性；企业版除包含专业版全部的内容外，还有自动化构件管理器等工具，使得专业编程人员能够开发功能强大的组骨子里分布式应用程

21、序。 VB是一种可视化的、面向对象和采用事件驱动方式的结构化高级程序设计语言，可用于开发Windows环境下的各类应用程序。它简单易学、效率高，且功能强大可以与Windowsr专业开发工具SDK相媲美。在Visual Basic环境下，利用事件驱动的编程机制、新颖易用的可视化设计工具，使用Windows内部的广泛应用程序接口（API）函数，以用动态链接库（DLL）、对象的链接与世隔嵌入（OLE）、开放式数据连接（ODBC）等技术，可以高效、快速地开发Windows环境下功能强大、图形界面丰富的应用软件系统。随着版本的提高，Visual Basic的功能也越来越强。5.0版以后，Visual B

22、asic推出了中文版，与前个版本相比，其功能有了很大提升。 但是，功能再强大，Visual Basic仍然有一个缺点：在没有MSVBVM*.DLL的计算机上必须安装所需的DLL文件。用它可设计操作系统，不过，比较困难。 在二十一世纪初，microsoft公司推出Visual Studio 2003与Visual Basic之间有了重大变化，Visual Studio为各种编程工具做了一个平台，Visual Basic.NET可在这种平台上运行。相对于传统VB，有很大的不同。VB.Net，首次使用.Net构架进行可视化编程，并且能很好地与COM构架兼容。2005年Visual Studio 20

23、05则运用了NET 2.0的技术，更加的方便了程序员的工作。可是新的程序对系统配置要求也较高，需要微软.Net Framework 2.0以上的.Net构架支持。 2007年12月,微软(Microsoft)推出了Visual Studio 2008 Beta 2 发生了重大的变化(见附图)在代码输入的时候,可以比VB2005快很多,在非特殊的情况下,VB2008都会自动开启 自动完成关键字 这个命令 而且开始支持最新的.NET Framework 3.5 Beta 2 编程工具的角色跟计算机硬件一起在过去45年中已经逐步形成。 编程语言今天，例如Visual Basic，从仅仅几年以前的编程

24、语言非常不同。 与几年以前有货相比，Windows操作系统的视觉性质需要更先进的工具。 在有窗的环境之前，编程语言是你写计划用的一件简单的基于文本的工具。 今天你需要非常不仅仅是的一种语言； 你需要一种图表的开发工具， 能在窗口系统里面工作并且创建利用全部图解，多媒体的应用，在线，以及Windows 提供的multiprocessed 活动。 Visual Basic是这样的一件工具。 更多比语言, Visual.basic 让您引起与每个今天窗口操作系统相处融洽的方面的应用。 Visual.basic 5 进来三个味道: 标准版, 专业编辑, 并且企业版。 虽然这本书主要应付专业编辑, 标准版称学习的编辑和提供最少昂贵的方法对使用Visual.basic 。标准版给您完全开发环境, 编程语言, 并且许多同样用工具加工另一编辑提议。 如果您使用标准版, 您有一个强有力的程序设计工具。 某些人民显现出只以标准版和从未需要别的。虽然这条路线瞄准专业编辑为击中共同基础, 您能实际上运用整个24 小时路线如果您使用标准版; 您将发现另外的工具在这条路线甚而不得到的标准版。
