  1. Web Programming using ASP.NET Subject Code: 3351603 Unit-1:Intorduction -H. P. Jagad

  2. Unit-1: Introduction to .Net Framework & ASP.NET • XHTML, XML, CSS • Webpage, Application • Client Side v/s Server Side Scripting • Limitation of Classic ASP • ASP.Net & its features • .Net Framework Architecture • Execution Process • Shortcut Key • Quiz Unit-1

  3. XML vs HTML • XML was designed to carry data - with focus on what data is • HTML was designed to display data - with focus on how data looks • XML tags are not predefined like HTML tags. • XML = extensible Markup Language • XML was designed to store and transport data • XML is just information wrapped in tags. • Someone must write a piece of software to send, receive, store, or display it. Unit-1

  4. XHTML =XML+HTML EXtensibleHyperText Markup Language • XHTML is stricter than HTML • XHTML is supported by all major browsers • XHTML DOCTYPE is mandatory • The xmlns attribute in <html> is mandatory • <html>, <head>, <title>, and <body> are mandatory • XHTML elements must be properly nested, always be closed, be in lowercase Unit-1

  5. CSS • Contains style rules that are applied to elements in a web page. • CSS styles can be placed inline within a single HTML element, grouped in style block within the head section of a web page, or imported from a separate style sheet.

  6. Web Application: Collection of web pages. • Web Page: is file which travel across network and carry information from server to client which requested by client. • Stored on server. • Either static or dynamic. • Parts of WebSite • HTML (Hypertext Markup Language) ( Now XHTML= HTML + XML) • CSS (Cascading Style Sheet) • Client side coding and server Side coding • Database Unit-1

  7. Client Side Scripting • Scripts on the page are processed by the individual web browser that requested the page. • Limitation of HTML is static page. • Client side coding is interpreted by browser and run on the client • Can’t access server resources . • Ex: Javascript , or VBScript. • Client Side scripting executes in the browser after the page is loaded. • Client side scripting more appropriate for client side validation, Image rotation etc.

  8. Server Side scripting • Ex: PHP,JSP, Asp.Net • Executes on server side. • Easily access server resource. • Slower than client side scripting • Preferable for database task.

  9. Client Side v/s Server Side Unit-1

  10. Limitation of Classic ASP • Interpreted • Mixed Layout and Logic • Limited Development and Debugging Tools • No real State Management • Update file only when server is down (Difference between Classic ASP & ASP.NET) Unit-1

  11. What is .Net? • .Net is a platform that provides tools and technologies you need to build Networked Applications as well as Distributed Web Services and Web Applications. Unit-1

  12. ASP.NET • Is next generation of ASP • Is Microsoft Technology • Is a server side technology for creating dynamic web pages which executed by Internet server • Is a program that runs inside IIS. • IIS is a Microsoft Internet Server. • ASP.NET defines an application as sum of all files, pages, handlers, modules and executable codes that can be invoked or run in the scope of a given virtual directory on web application server

  13. Features of ASP.Net • Separation of Code from HTML • Support for compiled Languages • Use services provided by .net Framework • Completely Object Oriented Support • Graphical Development Environment • State Management • Update files while server is running • XML based configuration Files • Security Unit-1

  14. Features • Object Oriented Programming System • In built memory System • Rich Set of classes • Multi language Multi Device Support • Faster & Easy Development of Web Applications • XML Support • Ease of Deployment & Configuration Unit-1

  15. .Net Framework Architecture • Metadata • Namespace • GAC(Global Assembly Cache) • Assemblies • CLR(Common Language Runtime) • CLS(Common Language Specification) • CTS(Common Type System) • JIT • FCL(.Net Framework Class Library) • GC(Garbage Collection) • MSIL(MicroSoft Intermediate Language/CIL) Unit-1

  16. Execution Process Unit-1

  17. Unit-1

  18. Source Code in any Language Language Compiler PE MSIL GAC Assemblies CLR JIT Metadata • CTS HTML Page GC CLS FCL • Native Code Uses Namespace Unit-1

  19. Unit-1

  20. Shortcut Key: Open Visual Studio: devenv Run your webpage: F5 Stop Debugging: Shift + F5 Code Editor View: F7 Form Designer View: Shift + F7 Property Window: F4 Command Window: Clrl + Alt + A Toolbox: Ctrl + Alt + X Server Explorer: Clrl + Alt + S Unit-1
