  14. Visual Studio 2008 VS 2008

  15. What VS 2008 Is • .Net development environment for distributed and dynamic Web applications. • Distributed applications are composed of disparate resources in multiple locations – the database might be in New York, the inventory control software in Los Angeles, and the data entry software in Miami. • Dynamic applications enable the user interact with the Web. • Supports any .Net-compliant language • Does not require IIS for debugging • File System • HTTP • FTP

  16. Creating a Web Site in VS2008

  17. ASP.Net in a Multi-tier Environment

  18. ASP.Net in a Multi-tier Environment(cont.) The work done by any application program can be divided into three general functions: • data storage & data access logic (DATA SERVICEs) • application logic (BUSINESS SERVICEs) • presentation logic (USER SERVICEs)

  19. The .Net Class Library • The .Net class library contains classes for building ASP.Net applications (pages).

  20. ASP.Net Pages and Web Forms • An ASP.Net Web page includes HTML and program code. • ASP.Net Web Forms can be arranged in two files by VS2008- default.aspx contains the actual HTML and layout- default.aspx.vb contains the majority of the page’s code

  21. Namespaces • A namespace is a hierarchical way to identify resources in .Net. It is a system to describe where objects are stored.House.FirstFloor.DiningRoom.ChinaCabinet • The example • Imports System.Net.Mail

  22. Sending Email via ASP.Net 3.5 • First provide a namespace to the classes in the top of your class module as follows:Imports System.Net.Mail • Then Create the message bodyDim Mail as New MailMessage(From, To, Subject, Body) • Specify the mail serverdim ms as new SmtpClient(“smtp.students.niu.edu”) • Send the Mailms.Send(Mail)

  23. Object Class • Object class is a conceptual representation of the properties and methods of an object. • Object.Property • Object.Method • WebForm controls appear as objects to your code (have properties and methods) • Standard Controls • Navigation Controls • Data Controls • Validation Controls • Login Controls

  24. The ASP.Net Advantages • ASP.Net is compiled, not interpreted. • Real programming languages • Event-based programming model • Separate Code from Content • Real Debugging • Server Controls/User controls • Support Web services
