Creating a MVC Web Application Project with a Class Library in VB.Net

Classes provide reusable code in the form of objects. A class library contains one or more classes that can be called on to perform specific actions. This walkthrough shows how to create a class library project in vb.net and incorporate it into a Web application project.

Prerequisites

In order to complete this walkthrough, you will need:

The .NET Framework version 3.5.
The SP1 release of Visual Web Developer 2010 Express.

The following procedures build upon each other. Therefore, you must follow the order of the procedures to successfully complete this walkthrough.

Creating the Class Library Project

To create the CDemoLib class library and the Customer class file

1. On the File menu, select New Project to open the New Project dialog box.

2. In the list of Windows project types, select Class Library, and then type CDemoLib in the Name box.

3. In Solution Explorer, right-click CDemoLib and then click Properties.

Notice that the Default namespace box contains CDemoLib. The root namespace is used to qualify the names of class in the assembly. For example, if two assemblies provide class named Customer, you can specify the Customer class by using CDemoLib.Customer.

Close the properties window.

4. In Solution Explorer, right-click CDemoLib, click Add, and then click Class.

The Add New Item dialog box is displayed.

5. Type Customer.cs in the Name box and then click Add to create the class.

A class named Customer is added to your class library.

6. In Solution Explorer, right-click Class1.cs and then click Delete.

This deletes the default class that is provided with the class library, because it will not be used in this walkthrough.

7. In the File menu, click Save All to save the project.

Creating the Class

Constructors control the way your class is initialized. Properties are values of the class that you can get and set. In Visual C#, all constructors have the same name as the class.

To add code to define the Customer class

· In the code editor, replace the existing code with the following code to define the Customer class in the CDemoLib class library.

Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Namespace CDemoLib
    Public Class Customer
        Private _age As Integer        Private _name As String
        Public Sub New()
            Age = 0
            Name = "Not available"        End Sub
        Public Property Age() As Integer            Get                Return _age
            End Get            Set                _age = value
            End Set        End Property        Public Property Name() As String            Get                Return _name
            End Get            Set                _name = value
            End Set        End Property    End ClassEnd Namespace

Adding the Class Library to a Web Application Project

To test the class, you must have a project that uses it. This project must be the first project that starts when you run the application.

To add the CDemoTest Web Application project as the startup project for the solution

1. In the File menu, click Add and then click New Project.

The Add New Project dialog box is displayed.

2. Under Project types, expand Visual Basic or Visual C#, and then click Web to display available Web templates.

3. In the Templates box, select ASP.NET Web Application.

4. In the Name box, type CDemoTest as the name of the new application.

5. Click OK.

creates the Web application project in the existing solution.

In order to use the Customer class, the client test project must have a reference to the class library project. After you add the reference, it is a good idea to add a using statement in C# (an Imports statement in Visual Basic) to the test application to simplify the use of the class.

To add a reference to the class library project

1. In Solution Explorer, right-click the References node underneath CDemoTest, and then click Add Reference.

2. In the Add Reference dialog box, select the Projects tab.

3. Double-click the CDemoLib class library project. CDemoLib will appear under the References node for the CDemoTest project.

4. In Solution Explorer, right-click Default.aspx and then click View Code.

Adding the reference to CDemoLib lets you use the fully qualified name of the Customer class, which is CDemoLib.Customer.

To add a using or Imports statement

· Add the following using statement (Imports in Visual Basic) at the top of the code editor window for the Default.aspx page.

Imports CDemoLib

· Adding this statement lets you omit the library name, and refer to the class type as Customer.

Using the Class from the Class Library

The CDemoTest Web application will call the class that is contained in the class library and display the results.

To add code to create and use a Customer object

1. In Solution Explorer, right-click Default.aspx and select View Designer.

2. From the Standard tab of the Toolbox, drag a Label control onto the design surface.

3. Double-click the design surface to display the Page_Load event handler.

4. In the Page_Load event handler add the following code:

Dim myCustomer As New Customer()
myCustomer.Name = "Alex Jendar"myCustomer.Age = 30
Label1.Text = "Name: " & myCustomer.Name + "<br/>Age: " & _ myCustomer.Age.ToString()

5. In the File menu, click Save All to save the solution.

To run and debug the CDemoTest project

1. Press CTRL+F5 to start the solution.

Notice that the Customer class properties are automatically displayed in the label control.

2. Close the browser window to return to the development environment.

How to print message using javascript

To print a statement, you can use alert or console.log.

alert("prosourcecode");
console.log("prosourcecode");

Semicolon can be omitted most of the time, but you should always add a semicolon, because if you don't, the compiler sometimes will get it wrong, resulting hard-to-find bugs.

Getting started javascript tutorials by example

This page will quickly get you started on JavaScript the language. You need to have basic understanding of the language before you can script the DOM/web.

Running JavaScript

To evaluate a piece of JavaScript code, you need to call it in a HTML file and view the file in browser.

Here's how to embed JavaScript into HTML. If you just have few lines of code, do:
If you have more than a few lines of code, put them in a file, and call it like this:

Use Browser's Web Developer Console:

In Google Chrome: 〖Tools ▸ JavaScript Console〗 .
In Firefox: 〖Tools ▸ Web Developer ▸ Web Console〗.
In Safari: 〖Develop ▸ Show Error Console〗.
In Internet Explorer 9: 〖Tools ▸ F12 Developer Tools〗.

Using node.js

Another good way to run JavaScript code is node.js. With node.js, you can run JavaScript like shell scripts in terminal.
On Linux, install by sudo apt-get install nodejs. Or get it at http://nodejs.org/.
You can run it interactively. Type node to start the interactive prompt. Type Ctrl+d to exit.
You can also run it as shell script. Save a JavaScript code in a file “myscript.js”. Then, you can run the script in shell like this: node myscript.js.

Tic-Tac-Toe or Noughts and Crosses Game Project in C++

Project Description: Tic-tac-toe game or Noughts and crosses (Xs and Os) game is a paper-and-pencil game of 2 players, in which Player1 put X and Player2 put O, marking the areas inside a 3×3 matrix. The player who succeeds in putting 3 various marks during a horizontal, vertical, or diagonal row wins the sport. This is a C++ project focus on logical algorithm to play and win game and a simple without graphics, text based game.

The simplicity of tit-tat-toe makes it ideal as a pedagogic tool for teaching the ideas of excellent equity and therefore the branch of computing that deals with the looking of game trees. It’s easy to put in writing a worm to play tit-tat-toe dead, to enumerate the 765 basically totally different positions, or the 26,830 doable games up to rotations and reflections on this game area.
