制作多媒体网站 第1篇

网络教学是在Internet上进行的活动,即利用计算机网络进行服务、信息等交流,而交流就涉及到了网站设计和网络学习,网络教学作为一门独立的专业课程,已初具规模,网络学习也已得到了很好的发展。一些教学网站已经成功地给人们的生活带来了巨大的影响,网络学习也为人们的生活带来了巨大的改变,人们足不出户就可以在线学习和掌握自己所需要的知识,也可以与专业的权威教授进行交流,解答疑难问题。全国各大高校也应全球化下的信息技术的高速发展的需要,都相应的开设了网上精品课堂,而怎样使用好网站进行网络学习,就需要进行这方面的学习了。本课题的选择就是针对现今世界网络学习的发展对现代人的要求而来,可以帮助人们更好的通过对多媒体这门课程的学习,对网上教学专业课程的有关知识有所了解和掌握,更好的利用现代网络技术,使现代生活更加的便捷美好。全球化下的信息技术的高速发展,网上教学的发展也与日俱增。网上教学网站作为网络学习的桥梁,其设计和实现正如传统经济下企业店铺的经营和管理,凭借自身各方面的优势,网站在沟通和促进整个行业的发展方面都有至关重要的作用。

多媒体网站规划与设计是网上教学需要的归纳,总结的结果。一旦网站设计成功,同学们就可以随时随地,在只要拥有网络的条件下,学习网上教学的专业知识。还有就是,完全可以不用特意地去找专业的老师,花大把的钱去在有限的时间里去速成,在这里,只需要在留言板上写下你的疑问,专业的权威教授就会尽快地解答你的问题。总之一句话,网站的建设,完全是为了您的方便。

制作多媒体网站 第2篇

由于系统实现网上教学教育的功能,所以最基本的需求就是进行网上教学知识的宣传和学习,所以在功能方面要十分注重教学功能。在系统设计时,要充分考虑到以下关键点:

1、系统操作尽量简约,尽可能地仿真网上教学的实际操作。

2、要充分考虑参与学习者的实际知识掌握情况,要做到循序渐进的学习。

3、在系统安全方面要做到可靠,定期做好数据备份,以防意外情况。

随着计算机技术的发展和网络人口的增加,网络世界也越来越广博,越来越丰富,网络信息宣传已经是其中最大的一项功能。我们相信要不了太长的时间,用户就可以在网络世界上获得他们在现实世界上可以获得而不方便获得的所有信息。可行性研究的目的,就是用最小的代价在尽可能短的时间内确定问题是否能够解决。要达到这个目的,必须分析几种主要的可能解法的利弊,从而判断原定的系统规模和目标是否现实,系统完成后所能带来的效益是否大到值得投资开发这个系统的程度。。

系统的可行性分析主要包括经济上的可行性,技术上的可行性,操作上的可行性和法律上的可行性。本系统的可行性分析如下:

由于开发此多媒体网站所需的硬件(计算机及相关硬件)和软件环境(ASP+SQL SERVER),市场上都容易购买到或从相关网站下载,系统成本主要集中在本网站的开发与维护上。而一旦此网站投入使用,不仅可以减少学生的学习强度,提高学习效率,而且方便了学生和教师,减少不必要的书本浪费,节能环保,打破了传统的教学模式,也为网站的进一步推广创造了条件,而且,目标网站不是很复杂,开发的周期较短,人员经济支出不大,为学生老师所节省的大量时间、财力产生的效益将远远大于本网站系统的开发成本,所以从经济方面讲开发此系统是可行的。

多媒体网站的开发基于B/S模式,主要包括前端应用程序的开发以及后台数据库的建立和维护两个方面。对于前者要求应具备功能完备、易于使用等特点,而对于后者则要求能建立数据一致性和完整性强、安全性好的数据库。

本系统拟采用ASP和SQL SERVER分别作为前端和后端的开发工具,因此从技术方面讲开发此系统是可行的。

本系统是一个基于Web的多媒体网站,是Web技术应用于网上宣传中的产物,是网上教学教育发展历史上的一个新阶段。系统基于Web的工作界面,使您无论身处何地,都能在浏览器中直接对新闻进行录入、浏览、修改、删除、查阅等新闻管理工作。在操作使用上十分方便,只需连上网,在自己的电脑上通过Web浏览器就可使用本系统,同时所有的操作都是基于Web的操作方式,如:链接、按钮、文本框等等。所有的操作通过浏览器完成,客户端不需要配置其他应用软件,用户不需培训。因此,在操作使用上,本系统简单、方便,易于使员工们接受,本系统尽力为用户着想,因而该系统是方便可操作的。

    即该平台的开发会不会在社会上引起侵权或其它责任问题。因为该平台是作为毕业设计与商业无关,又因为是自主开发设计,因此不会构成侵权,在法律上是可行的。

软件测试的目的决定了如何去组织测试。如果测试的目的是为了尽可能多地找出错误,那么测试就应该直接针对软件比较复杂的部分或是以前出错比较多的位置。如果测试目的是为了给最终用户提供具有一定可信度的质量评价,那么测试就应该直接针对在实际应用中会经常用到的商业假设。

不同的机构会有不同的测试目的;相同的机构也可能有不同测试目的,可能是测试不同区域或是对同一区域的不同层次的测试。

在谈到软件测试时,许多人都引用Grenford J. Myers在《The Art of Software Testing》一书中的观点:

①、软件测试是为了发现错误而执行程序的过程;

②、测试是为了证明程序有错,而不是证明程序无错误。

③、一个好的测试用例是在于它能发现至今未发现的错误;

④、一个成功的测试是发现了至今未发现的错误的测试。

这种观点可以提醒人们测试要以查找错误为中心,而不是演示软件的正确。

首先,测试并不仅仅是为了要找出错误。通过分析错误产生的原因和错误的分布特征,可以帮助项目管理者发现当前所采用的软件过程的缺陷,以便改进。同时,这种分析也能帮助我们设计出有针对性地检测方法,改善测试的有效性。

其次,没有发现错误的测试也是有价值的,完整的测试是评定测试质量的一种方法。详细而严谨的可靠性增长模型可以证明这一点。例如 Bev Littlewood发现一个经过测试而正常运行了n小时的系统有继续正常运行n小时的概率。

编码的目的是实现系统的设计,选择某种程序设计语言编写程序来完成设计过程产生的功能模块的实现。

测试过程的主要任务是尽可能发现软件中存在的错误。

经过尽可能多的软件功能用例测试,基本上达到了软件设计的目的和功能性的要求。现在把软件测试过程中出现的一些错误列出来。

(1) ASP中的中文问题

编写ASP时,有两种中文无法正确显示的情况:一种是当在编写ASP页面时,没有说明用哪种语言显示,这样,页面显示乱码,解决办法是在ASP页面开始处加入<%@ page contentType =”text/html;charset=gbk”%>

另一情况是当从数据库读取含有中文字符的数据,或把含有中文字符的数据写入数据库时,有时会不显示中文,而显示“?”,同样在SQL设置中选择语言为gbk即可。

(2) ASP中的页面验证

进行ASP中的页面验证时,通常采用正则表达式,常用的包括:只为数字、字母数字或下划线、汉字、邮箱、电话等等。

(3) HTTP 404 错误

此错误为路径出错,根据提示调整好跳转路径,即可排除错误。

(4) 数据库问题

在设计数据库时,理解表之间的关联,成功地创建表非常重要,在后期遇到问题时,再去重新审查修改表,那是一项非常烦人的劳动。建议表的ID自动生成,方便用户操作。

is a unified Web development model that includes the services necessary for you to build enterprise-class Web applications with a minimum of coding. is part of the .NET Framework, and when coding applications you have access to classes in the .NET Framework. You can code your applications in any language compatible with the common language runtime (CLR), including Microsoft Visual Basic, C#, JScript .NET, and J#. These languages enable you to develop applications that benefit from the common language runtime, type safety, inheritance, and so on.

includes:

The page and controls framework is a programming framework that runs on a Web server to dynamically produce and render Web pages. Web pages can be requested from any browser or client device, and renders markup (such as HTML) to the requesting browser. As a rule, you can use the same page for multiple browsers, because renders the appropriate markup for the browser making the request. However, you can design your Web page to target a specific browser, such as Microsoft Internet Explorer 6, and take advantage of the features of that browser. supports mobile controls for Web-enabled devices such as cellular phones, handheld computers, and personal digital assistants (PDAs).

Web pages are completely object-oriented. Within Web pages you can work with HTML elements using properties, methods, and events. The page framework removes the implementation details of the separation of client and server inherent in Web-based applications by presenting a unified model for responding to client events in code that runs at the server. The framework also automatically maintains the state of a page and the controls on that page during the page processing life cycle.

The page and controls framework also enables you to encapsulate common UI functionality in easy-to-use, reusable controls. Controls are written once, can be used in many pages, and are integrated into the Web page that they are placed in during rendering.

The page and controls framework also provides features to control the overall look and feel of your Web site via themes and skins. You can define themes and skins and then apply them at a page level or at a control level.

In addition to themes, you can define master pages that you use to create a consistent layout for the pages in your application. A single master page defines the layout and standard behavior that you want for all the pages (or a group of pages) in your application. You can then create individual content pages that contain the page-specific content you want to display. When users request the content pages, they merge with the master page to produce output that combines the layout of the master page with the content from the content page.

All code is compiled, which enables strong typing, performance optimizations, and early binding, among other benefits. Once the code has been compiled, the common language runtime further compiles code to native code, providing improved performance.

includes a compiler that will compile all your application components including pages and controls into an assembly that the hosting environment can then use to service user requests.

In addition to the security features of .NET, provides an advanced security infrastructure for authenticating and authorizing user access as well as performing other security-related tasks. You can authenticate users using Windows authentication supplied by IIS, or you can manage authentication using your own user database using forms authentication and membership. Additionally, you can manage the authorization to the capabilities and information of your Web application using Windows groups or your own custom role database using roles. You can easily remove, add to, or replace these schemes depending upon the needs of your application.

always runs with a particular Windows identity so you can secure your application using Windows capabilities such as NTFS Access Control Lists (ACLs), database permissions, and so on. For more information on the identity of ,

provides intrinsic state management functionality that enables you to store information between page requests, such as customer information or the contents of a shopping cart. You can save and manage application-specific, session-specific, page-specific, user-specific, and developer-defined information. This information can be independent of any controls on the page.

offers distributed state facilities, which enable you to manage state information across multiple instances of the same application on one computer or on several computers.

applications use a configuration system that enables you to define configuration settings for your Web server, for a Web site, or for individual applications. You can make configuration settings at the time your applications are deployed and can add or revise configuration settings at any time with minimal impact on operational Web applications and servers. configuration settings are stored in XML-based files. Because these XML files are ASCII text files, it is simple to make configuration changes to your Web applications. You can extend the configuration scheme to suit your requirements.

includes features that enable you to monitor health and performance of your application. health monitoring enables reporting of key events that provide information about the health of an application and about error conditions. These events show a combination of diagnostics and monitoring characteristics and offer a high degree of flexibility in terms of what is logged and how it is logged.

supports two groups of performance counters accessible to your applications:

takes advantage of the run-time debugging infrastructure to provide cross-language and cross-computer debugging support. You can debug both managed and unmanaged objects, as well as all languages supported by the common language runtime and script languages.

In addition, the page framework provides a trace mode that enables you to insert instrumentation messages into your Web pages.

supports XML Web services. An XML Web service is a component containing business functionality that enables applications to exchange information across firewalls using standards like HTTP and XML messaging. XML Web services are not tied to a particular component technology or object-calling convention. As a result, programs written in any language, using any component model, and running on any operating system can access XML Web services.

includes an extensible hosting environment that controls the life cycle of an application from when a user first accesses a resource (such as a page) in the application to the point at which the application is shut down. While relies on a Web server (IIS) as an application host, provides much of the hosting functionality itself. The architecture of enables you to respond to application events and create custom HTTP handlers and HTTP modules.

includes enhanced support for creating designers for Web server controls for use with a visual design tool such as Visual Studio. Designers enable you to build a design-time user interface for a control, so that developers can configure your control's properties and content in the visual design tool.

Introduction to the C# Language and the .NET Framework  C# is an elegant and type-safe object-oriented language that enables developers to build a wide range of secure and robust applications that run on the .NET Framework. You can use C# to create traditional Windows client applications, XML Web services, distributed components, client-server applications, database applications, and much, much more. Microsoft Visual C# 2005 provides an advanced code editor, convenient user interface designers, integrated debugger, and many other tools to facilitate rapid application development based on version of the C# language and the .NET Framework.

Note

The Visual C# documentation assumes that you have an understanding of basic programming concepts. If you are a complete beginner, you might want to explore Visual C# Express Edition, which is available on the Web. You can also take advantage of any of several excellent books and Web resources on C# to learn practical programming skills.

C# syntax is highly expressive, yet with less than 90 keywords, it is also simple and easy to learn. The curly-brace syntax of C# will be instantly recognizable to anyone familiar with C, C++ or Java. Developers who know any of these languages are typically able to begin working productively in C# within a very short time. C# syntax simplifies many of the complexities of C++ while providing powerful features such as nullable value types, enumerations, delegates, anonymous methods and direct memory access, which are not found in Java. C# also supports generic methods and types, which provide increased type safety and performance, and iterators, which enable implementers of collection classes to define custom iteration behaviors that are simple to use by client code.

As an object-oriented language, C# supports the concepts of encapsulation, inheritance and polymorphism. All variables and methods, including the Main method, the application's entry point, are encapsulated within class definitions. A class may inherit directly from one parent class, but it may implement any number of interfaces. Methods that override virtual methods in a parent class require the override keyword as a way to avoid accidental redefinition. In C#, a struct is like a lightweight class; it is a stack-allocated type that can implement interfaces but does not support inheritance.

In addition to these basic object-oriented principles, C# facilitates the development of software components through several innovative language constructs, including:

If you need to interact with other Windows software such as COM objects or native Win32 DLLs, you can do this in C# through a process called _Interop._ Interop enables C# programs to do just about anything that a native C++ application can do. C# even supports pointers and the concept of _unsafe_ code for those cases in which direct memory access is absolutely critical.

The C# build process is simple compared to C and C++ and more flexible than in Java. There are no separate header files, and no requirement that methods and types be declared in a particular order. A C# source file may define any number of classes, structs, interfaces, and events.

C# programs run on the .NET Framework, an integral component of Windows that includes a virtual execution system called the common language runtime (CLR) and a unified set of class libraries. The CLR is Microsoft's commercial implementation of the common language infrastructure (CLI), an international standard that is the basis for creating execution and development environments in which languages and libraries work together seamlessly.

Source code written in C# is compiled into an intermediate language (IL) that conforms to the CLI specification. The IL code, along with resources such as bitmaps and strings, is stored on disk in an executable file called an assembly, typically with an extension of .exe or .dll. An assembly contains a manifest that provides information on the assembly's types, version, culture, and security requirements.

When the C# program is executed, the assembly is loaded into the CLR, which might take various actions based on the information in the manifest. Then, if the security requirements are met, the CLR performs just in time (JIT) compilation to convert the IL code into native machine instructions. The CLR also provides other services related to automatic garbage collection, exception handling, and resource management. Code that is executed by the CLR is sometimes referred to as _managed code,_ in contrast to _unmanaged code_ which is compiled into native machine language that targets a specific system. The following diagram illustrates the compile-time and run time relationships of C# source code files, the base class libraries, assemblies, and the CLR.

Language interoperability is a key feature of the .NET Framework. Because the IL code produced by the C# compiler conforms to the Common Type Specification (CTS), IL code generated from C# can interact with code that was generated from the .NET versions of Visual Basic, Visual C++, Visual J#, or any of more than 20 other CTS-compliant languages. A single assembly may contain multiple modules written in different .NET languages, and the types can reference each other just as if they were written in the same language.

In addition to the run time services, the .NET Framework also includes an extensive library of over 4000 classes organized into namespaces that provide a wide variety of useful functionality for everything from file input and output to string manipulation to XML parsing, to Windows Forms controls. The typical C# application uses the .NET Framework class library extensively to handle common _plumbing_ chores.

SQL Server 2000

是一个统一的 Web 开发模型,它包括您使用尽可能少的代码生成企业级 Web 应用程序所必需的各种服务。 作为 .NET Framework 的一部分提供。当您编写 应用程序的代码时,可以访问 .NET Framework 中的类。您可以使用与公共语言运行库 (CLR) 兼容的任何语言来编写应用程序的代码,这些语言包括 Microsoft Visual Basic、C#、JScript .NET 和 J#。使用这些语言,可以开发利用公共语言运行库、类型安全、继承等方面的优点的 应用程序。

包括:

页和控件框架是一种编程框架,它在 Web 服务器上运行,可以动态地生成和呈现 网页。可以从任何浏览器或客户端设备请求 网页, 会向请求浏览器呈现标记(例如 HTML)。通常,您可以对多个浏览器使用相同的页,因为 会为发出请求的浏览器呈现适当的标记。但是,您可以针对诸如 Microsoft Internet Explorer 6 的特定浏览器设计 网页,并利用该浏览器的功能。 支持基于 Web 的设备(如移动电话、手持型计算机和个人数字助理 (PDA))的移动控件。

网页是完全面向对象的。在 网页中,可以使用属性、方法和事件来处理 HTML 元素。 页框架为响应在服务器上运行的代码中的客户端事件提供统一的模型,从而使您不必考虑基于 Web 的应用程序中固有的客户端和服务器隔离的实现细节。该框架还会在页处理生命周期中自动维护页及该页上控件的状态。

使用 页和控件框架还可以将常用的 UI 功能封装成易于使用且可重用的控件。控件只需编写一次,即可用于许多页并集成到 网页中。这些控件在呈现期间放入 网页中。

页和控件框架还提供各种功能,以便可以通过主题和外观来控制网站的整体外观和感觉。可以先定义主题和外观,然后在页面级或控件级应用这些主题和外观。

除了主题外,还可以定义母版页,以使应用程序中的页具有一致的布局。一个母版页可以定义您希望应用程序中的所有页(或一组页)所具有的布局和标准行为。然后可以创建包含要显示的页特定内容的各个内容页。当用户请求内容页时,这些内容页与母版页合并,产生将母版页的布局与内容页中的内容组合在一起的输出。

所有 代码都经过了编译,可提供强类型、性能优化和早期绑定以及其他优点。代码一经编译,公共语言运行库会进一步将 编译为本机代码,从而提供增强的性能。

包括一个编译器,该编译器将包括页和控件在内的所有应用程序组件编译成一个程序集,之后 宿主环境可以使用该程序集来处理用户请求。

除了 .NET 的安全功能外, 还提供了高级的安全基础结构,以便对用户进行身份验证和授权,并执行其他与安全相关的功能。您可以使用由 IIS 提供的 Windows 身份验证对用户进行身份验证,也可以通过您自己的用户数据库使用 Forms 身份验证和 成员资格来管理身份验证。此外,可以使用 Windows 组或您自己的自定义角色数据库(使用 角色)来管理 Web 应用程序的功能和信息方面的授权。您可以根据应用程序的需要方便地移除、添加或替换这些方案。

始终使用特定的 Windows 标识运行,因此,您可以通过使用 Windows 功能(例如 NTFS 访问控制列表 (ACL)、数据库权限等等)来保护应用程序的安全。

提供了内部状态管理功能,它使您能够存储页请求期间的信息,例如客户信息或购物车的内容。您可以保存和管理应用程序特定、会话特定、页特定、用户特定和开发人员定义的信息。此信息可以独立于页上的任何控件。

提供了分布式状态功能,使您能够管理一台计算机或数台计算机上同一应用程序的多个实例的状态信息。

通过 应用程序使用的配置系统,可以定义 Web 服务器、网站或单个应用程序的配置设置。您可以在部署 应用程序时定义配置设置,并且可以随时添加或修订配置设置,且对运行的 Web 应用程序和服务器具有最小的影响。 配置设置存储在基于 XML 的文件中。由于这些 XML 文件是 ASCII 文本文件,因此对 Web 应用程序进行配置更改比较简单。您可以扩展配置方案,使其符合自己的要求。

包括可监视 应用程序的运行状况和性能的功能。使用 运行状况监视可以报告关键事件,这些关键事件提供有关应用程序的运行状况和错误情况的信息。这些事件显示诊断和监视特征的组合,并在记录哪些事件以及如何记录事件等方面提供了高度的灵活性。

支持两组可供应用程序访问的性能计数器:

利用运行库调试基础结构来提供跨语言和跨计算机调试支持。可以调试托管和非托管对象,以及公共语言运行库和脚本语言支持的所有语言。

此外, 页框架提供使您可以将检测消息插入 网页的跟踪模式。

支持 XML Web services。XML Web services 是包含业务功能的组件,利用该业务功能,应用程序可以使用 HTTP 和 XML 消息等标准跨越防火墙交换信息。XML Web services 不用依靠特定的组件技术或对象调用约定。因此,用任何语言编写、使用任何组件模型并在任何操作系统上运行的程序,都可以访问 XML Web services。

包括一个可扩展的宿主环境,该环境控制应用程序的生命周期,即从用户首次访问此应用程序中的资源(例如页)到应用程序关闭这一期间。虽然 依赖作为应用程序宿主的 Web 服务器 (IIS),但 自身也提供了许多宿主功能。通过 的基础结构,您可以响应应用程序事件并创建自定义 HTTP 处理程序和 HTTP 模块。

中提供了对创建 Web 服务器控件设计器(用于可视化设计工具,例如 Visual Studio)的增强支持。使用设计器可以为控件生成设计时用户界面,这样开发人员可以在可视化设计工具中配置控件的属性和内容。
