FROM VB6 TO VB.NET

The switch form the old visual studio versiom6 to newer Visual Studio .NET to Create Visual BAsic
programs represents a update in technology . It represents far more than changing of a version name. When upgrading from Visual Studio 6 , Instead of naming it version , Microsoft used the term .NET as the name of the new version to denate the difference that it carries from the older technology .Faculty members teaching programming courses in visual  basic have to learn about the changes in new version of visual basic in order to Switch from teaching the older vb6.

The Changes in VB programs are not only ones of terminology . Instead they reflect structural changes in how files are created and grouped and how they are then divided to provide the final functianality of program. In order to explain these STRUCTURAL CHANGES between the two versions of VB, we first create a simple project in VB6 to see different files and folders it created . We called this project "Proj1" and then checked then checked the files created from this program. Three files were created from this simple program in VB6. Proj1.vbp. for project file, proj1.frm for the form file and Proj1.vbw for workspace file. We then proceeded to create the same program in VB.NET and found that it created 14 files and stored them in 6 folders.

CoNCEPT OF CLASSES In VB.NET Not in VB6

Object oriented is not new to vb environment . It is used in the older vb6 environment. Most Textbooks did not cover this subject in depth . VB.NET can be taught without explaining classes and objects .

Public class frmRentals.........

        Inherits system.windows.forms.form

These lines are usually displayed at beginning of visual basic program in vb.net environment.This shows the nature of move towards OOPS concept in VB.NET. VB.NET includes a code generated code, but students can see it and may cause errors if they modify it. when user want to hidden code then they can click on + sign.

USING TEXT FILES IN VB.NET (VISUAL STUDIO 2010)

    USING TEXT FILES IN VB.NET (VISUAL STUDIO 2010)

    * Files are good means of transfer of data during Runtime in An Application .

   * FILES ARE BETTER IF WE HAVE LESS AMOUNT OF DATA TO SEND AND RECEIVE FROM TEXTFILES.

* FOR SMALL APPLICATIONS FILES ARE BETTER AS COMPARED TO DATABASE BECAUSE DATABASE CONSUMES MORE TIME AS COMPARED TO TEXTFILES FOR FETCHING DATA FROM DATABASE

* BUT FOR LARGE APPLICATIONS FILES ARE CONSIDERED TO BE UNABLE TO MANAGE LARGE DATA IN WELL-DEFINED ORGANISED WAY.

STREAMREADER is Used in Visual Basic . NET to Read Data from TextFiles . An Object is first created of type streamreader that is inbuilt class described under Namespace System.io.Streamreader

STREAMWRITER is Used In Visual Basic .Net to Write Data to TextFiles. An Object is first created of type streamwriter that is inbuilt class described under Namespace System.io.Streamwriter

A peek() function is used to detect the end of file while reading the data from file

EXAMPLE TO SHOW USE OF FILES :-

READ DATA FROM TEXT FILE

Create Reader Object 

A File is read by creating a file Reader object is created by declaring a object of type system.io.streamreader Namespace as follows :-

Dim objreader As  System.IO.StreamReader = New System.IO.StreamReader( "path of text file" )

Here, 

           objreader is object of type streamreader in system.io Class That is used to read the Stream of Data From Text files . An object is similar like we create a variable of basic Data Types .

          

            System - It is a Main Namespace 

            IO - It is a Sub namespace included in system Namespace

            Streamreader - It is a Class of Type IO Namespace

Read Data

TextBox1.Text = objreader.ReadLine() --------(1)

In this Streamreader object objreader reads Single line from TextFile Whose path is given

TextBox1.Text = objreader.Read()-------------(2)

In this Streamreader object objreader reads Single Characte from TextFile Whose path is given

TextBox1.Text = objreader.ReadToEnd()------(3)

In this Streamreader object objreader reads Whole Data from TextFile Whose path is given

WRITE DATA TO TEXT FILE

A File is written by creating a file writter object is created by declaring a object of type system.io.streamwriter Namespace as follows :-

Dim objwriter As  System.IO.StreamWriter = New System.IO.StreamWriter( "path of text file" )

Here, 

           objwriter is object of type streamwriter in system.io Class That is used to write the Stream of Data to Text files . An object is similar like we create a variable of basic Data Types .

          

            System - It is a Main Namespace 

            IO - It is a Sub namespace included in system Namespace

            Streamwriter - It is a Class of Type IO Namespace

Write Data

TextBox1.Text = objwriter.Writeline() --------(1)

In this StreamWriter object objwriter Writes Single line To TextFile Whose path is given

TextBox1.Text = objreader.Read()-------------(2)

In this StreamWriter object objwriter Writes Single Characte To TextFile Whose path is given

CREATING AND USING VARIABLES IN VISUAL BASIC.NET

A Variable is Declared In following format in visual basic.NET :-

Dim variable-name As Datatype

* where Dim is a keyword Used For Creating Variable in Visual Basic.

* Variable-name is Name of variable 

* As is a Keywork used to Define Datatype of variable after it

* Datatype is Type of Data That the Data is going to Accept

EXAMPLE 1 :-

Dim msg as string 

msg = "Hello How Are You"

Msgbox(msg)

This code will message "Hello How Are You" With Default Ok Button

EXAMPLE 2 :-

Dim msg as string 

Dim msg1 as string

msg = "Hello How"

msg1= "Are You"

Msgbox(msg + msg1)

This code will message "Hello How Are You" With Default Ok Button

Commom Language Runtime (CLR) In VB.NET

It is common managed environment where all the .net programs run. Supports multiple languages and has garbage collection.

The .net Framework provides runtime environment which runs the code and provides services that make the development process easier. This runtime environment in .NET Framework is called as Common Language Runtime. The CLR site at the very heart of managed code. Common Language Runtime is the generalized multi-language, reflexive execution engine on which code originally written in various languages runs. At a higher level, CLR is simply an engine that takes in Intermediate Language instructions, translated them into machine instructions and executes them. 

When compiling to managed code, the compiler translated your source code into Microsoft Intermediate Language , Which is a CPU independent set of instructions can  be efficiently converted to native code. Intermediate Language is a binary assembly language that is compiled at runtime down to whatever machine language is appropriate for the host CPU.

FEATURES OF CLR

1. Automatic Memory Management :- The CLR provides the Garbage collection feautre for managing the like time of object. This relives programmer from memory management task.

2. Standard Type System :- The CLR implement a formal specification called Common Type System . CTS is important part of rules that ensures that objects written in different language can interact with each other.

3. Platform Independence :- The Compiler compiles code language, which is CPU independent . This means that the code can be executed from any  platform that supports .NET CLR.

4. Security Management :- In .Net platform, security is achieved through the code access security {CAS} . In the model, CLR enforces the restriction an managed code through the object called "permissions". The CLR allows the code to perform only that task for which it has permission. In other words, the CAS model specifies what the code can access instead of specifies who can access resources.

BENEFITS OF CLR

1. Performance improvement

2. The ability to easily use components developed in other languages.

3. Extensuble types provide by library. 

4. New language features such as inheritance, interfaces etc.

5. very strong type safety.

6. Syntax and semantics are similar to C or C++
