ASP.NET Web Application

project template

Similar projectstructure toVisual Studio 2003

Provides tighter control

over a project

ASP.NET Web Siteproject template

Easier to use

Provides more featuresand additional flexibility

Web Application Types and File Structure


10/30

Web Application Files

Web application files

ASP.NET Web Forms (.aspx)

ASP.NET Web services (.asmx)

Classes and code-behind pages (.vb or .cs)

Global application classes (.asax)

Web.config file

Other files

Files not based on a programming language


11/30

Demonstration: Creating a Web Application Project

Lesson: Overview of the Microsoft .NET-BasedLanguages

Multiple Language Support

The Common Language Runtime

Runtime Compilation and Execution

What Are Namespaces?

Comparison of the Microsoft .NET-Based Languages


15/30

Multiple Language Support

The .NET Framework supports many languages

More than 20 languages currently supported

Microsoft provides languages such as Visual Basic,Visual C# and C++

Benefits of multiple-language support

Code modules are reusable

API access is the same for all languages

The right language is used for the right task

Performance is roughly equal between all languages


16/30

The Common Language Runtime

One runtime for all .NET-based Languages

Manages threads and memory

Garbage collection

Enforces code security

Eliminates DLL versioning problems Multiple versions of a DLL can run simultaneously

Applications can specify a version of a DLL to use

18/30

What Are Namespaces?

Group related classes

Logical, not physical, grouping

Namespaces are hierarchical

Decrease naming conflicts

Keyword: using (Visual C#), Imports (Visual Basic)

Implicit and explicit object declaration

[Visual C#]using System.Data.SqlClient;

[Visual Basic]Imports System.Data.SqlClient


19/30

Comparison of the Microsoft .NET-Based Languages

.NET Framework class library is the same regardless of

language Performance

All languages are compiled to MSIL

Only performance difference is how each language compilercompiles to MSIL

The runtime compiles all MSIL the same, regardless of itsorigin

Development experience

Visual C# is appropriate for Java, C, and Visual C++developers

Visual Basic is appropriate for Visual Basic 6.0 developers

Browser compatibility

ASP.NET code is server-side code, so browser compatibility isnot an issue


20/30

Lesson: Creating a Component by UsingVisual Studio 2008

What Are Classes and Components?

Creating a Class

Accessing Components in an ASP.NET Web Form

Demonstration: Creating a Class in Visual Studio 2008


21/30

What Are Classes and Components?

Classes are groups of code with no user interface

Components are compiled classes

Components are compiled as DLL files

Components are used for sharing code betweenapplications

Webapplication

Webapplication

Windowsapplication

Component


22/30

Creating a Class

Create a Class Library project in Visual Studio 2008

Visual Studio 2008 creates a default namespace

Create methods of the class

[Visual Basic]Public Class ShippingFunction CalShipping (ByVal price As Single) As Single...Return (cost)

End FunctionEnd Class

[Visual C#]public class Shipping{

public Single CalShipping (Single price){...return cost;

}}


23/30

Namespace CompanyAClass ShippingFunction CalShipping ()

End ClassEnd Namespace

namespace CompanyA{class Shipping{public void CalShipping () { }

}}

[Visual Basic]Dim shippingObject As New _CompanyA.Shipping

Add a reference to the DLL

Instantiate the class object:

Use the object:

[Visual C#]CompanyA.Shipping shippingObject =new CompanyA.Shipping();

cost =shippingObject.CalShipping(price);

cost = _shippingObject.CalShipping(price)

Accessing Components in an ASP.NET Web Form

component.dll component.dll


24/30

Demonstration: Creating a Class in Visual Studio 2008

Create a new Class Library project

Create a method that returns a string

Call the class from an ASP.NET page

Create a class in the App_Code folder

When you create a Web site, what folders or files doesSolution Explorer display?

Can you think of a reason why Default.aspx has an

associated code-behind file?

How can you add projects to a Web site?

What type of references can you add to your Web site?
