Create a Class =

Class <Class Name>
........}
........} - Body
........}
End Class

or

Right Click on Project in Solution Explorer
Click Add -> then Click on New Item
Then Select VB Class then change the name and Click Add

Mcn you cant set property or method in a class class is only a structure please i think the question is not correct please check it and tell me bro

Shared Property Means that you can share it with other methods or classes it can be a global variable

Ex:

Public number As Integer

 

[DragonFox]

Mcn For your Second question i think u mean that how to define properties and methods in a class ne

So following is da examples

Properties are variables which u use to store data

To create a property

<Scope> <Variable Name> As <Data Type>

Example :

Dim Number As Integer
Private Name As String
Public Status As Boolean


Method is a piece of code which you define to do a specific task in VB.NET it has 2 types of methods
1 - With a return type - Where the method return a value
2 - With no return type - No value is returned

but in other languages there is only one type of method for both of this


1 method with return type are called functions

<Scope> Function <Function Name>()
.......
.........
......
Return value
End Function

Example

Private Function CalculateTotal()
Dim num As Interger
num = 1 + 1
return num
End Function


2 - method with no return are called subs or simply methods

<Scope> Sub <Method Name>
............
........
......
End Sub

Example

Private Sub Display()
me.txtName.Text = "Hello";
End Sub

 

[DragonFox]

Sample Class

Class Student

Private Name As String
Private Reg-Number As Integer
Private Address As String

End Class

 

[DragonFox]

Also Mcn there is a separate variables called property variables if you want to know about them just let me know they ar a bit advanced concept merging with object properties

1. Difference between JVM & MSIL(Microsoft Intermediate Language ) itz a huge topic bt 4 da absolute basic following are the thingz

JVM - Converts the Code to Java Byte Code and then execute the byte code as the program. the code is not readable by humans itz sole intention is to be executed by the machine dose both compilation and interpretation and it supports only Java

MSIL - Converts Code to (.NET bytecode) Execution to CLI which is more human readable. MSIL was developed explicitly for JIT compilation. It supports several languages (VB.NET, C#.NET, C++) and has more explicit delineation between value and reference types

2. Explain

Class Library
Collection of Predefined Classes which are used to create applications by programmers.
The class library consist of Microsoft Classes and if needed user can add some also(advanced).

Common Language Runtime
[FONT=Verdana, Arial, Helvetica, sans-serif]The Common Language Runtime (CLR), is the runtime environment of the .NET framework, which manages the execution of code and provides services.
It gets the compiled code from the MSIL and interprets into machine readable language It has five components namely:[/FONT]

• 
  [*][FONT=Verdana, Arial, Helvetica, sans-serif]CTS - Common Type System [/FONT]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif]CLS - Common Language Specification [/FONT]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif]CIL - Common Intermediate Language [/FONT]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif]JIT - Just in Time Compiler [/FONT]
  [*][FONT=Verdana, Arial, Helvetica, sans-serif]VES - Virtual Execution System[/FONT]

3 Language support .NET

VB.NET (Visual Basic.NET)
C#.NET
C++
F#.NET (in Visual Studio 2005 and 2010 only)


mcn what is this course?

1 .3tire Architecture

View (Model) - This is the user interfaces of the application all the coding of data inputs and output are situated here

Business Layer - This contains all the logic of the program conditions loops etc...

Data Layer - All the data access is done here (INSERT,UPDATE,DELETE,SELECT) all the sql statements are executed in this layer

The architecture means developing the code in the above way by passing all the values through layers and executing the application logic this improves program readability, extendability and maintainability


2. Explain

Solution Explorer - Contains all the files and other projects regarding the current application

Server Explorer - this is used to manage connections to other servers like SQL Server, Windows Exchange etc...

Both is used to manage the client and server side of an application


3 Code (In Console View) - Coded in Visual Studio 2010

Module Module1

Sub Main()
Console.WriteLine("WELCOME TO VB.NET")
End Sub

End Module
