Comprehensive Guide to VB.NET Programming: Concepts and Applications

This document serves as a comprehensive guide to VB.NET programming, a modern, object-oriented language built on the .NET framework. It provides an in-depth look at VB.NET's features, including its object-oriented nature, component-oriented design, and strong programming highlights like Boolean conditions, custom garbage collection, and standard libraries. The document details the .NET framework, explaining its components like the Common Language Runtime (CLR) and class libraries, and how VB.NET integrates with other .NET languages. It offers step-by-step instructions for creating and running VB.NET programs using Visual Studio.NET IDE and the command line, along with detailed examples demonstrating ListBox, ComboBox, and ProgressBar controls. The document also includes code examples and diagrams. The content is very useful for students of computer science to learn and understand VB.NET programming concepts and application development.

Visual Basic.NET
Visual Basic.NET (VB.NET) is an article arranged PC programming tongue realized on
the .NET System. Despite the way that it is an advancement of commendable Visual Essential
lingo, it is not backward great with VB6, and any code written in the old variation does not total
under VB.NET.
Like all other .NET tongues, VB.NET has complete support for article arranged thoughts.
Everything in VB.NET is an article, including most of the primitive sorts (Short, Whole number,
Long, String, Boolean, et cetera.) and customer described sorts, events, and even gatherings. All
articles secures from the base class Item.
VB.NET is realized by Microsoft's .NET framework. In like manner, it has full access to each
one of the libraries in the .Net System. It's also possible to run VB.NET programs on Mono, the
open-source differentiating alternative to .NET, under Windows, and in addition even Linux or
Macintosh OSX.
The going with reasons make VB.Net a comprehensively used capable lingo:
Bleeding edge, comprehensively helpful.
• Item arranged.
• Segment masterminded.

• Simple to learn.
• Organized lingo.
• It produces capable tasks.
• It can be aggregated on an arrangement of PC stages.
• A bit of .Net Structure.
• Solid Programming Highlights VB.Net
VB.Net has different strong programming highlights that make it beguiling to colossal number of
programming specialists around the globe. Allow us to determine some of these components:
Boolean Conditions•
Customized Waste Gathering
• Standard Library

•Assembly Forming Properties and Occasions
• Representatives and Occasions Administration
• Simple to-use Generics
• Indexers
• Restrictive Accumulation
• Basic Multithreading
The .Net System
The .Net framework is a dynamic stage that helps you to make the going with sorts out of
usages:
Windows applications
• Web applications•

Web organizations
The .Net framework applications are multi-stage applications. The structure has been arranged in
a way that it can be used from any of the going with lingos: Visual Essential, C#, C++, Jscript,
and COBOL, et cetera.
Each one of these tongues can get to the structure and furthermore talk with each other.
The .Net framework contains a colossal library of codes used by the client lingos like VB.Net.
These tongues use object-arranged theory.
Taking after are a segment of the fragments of the .Net structure:
Fundamental Lingo Runtime (CLR)
The .Net Framework Class Library
Fundamental Lingo Specific
Fundamental Sort System
Metadata and Assemblages
Windows Shapes
ASP.Net and ASP.Net AJAX
ADO.Net
Windows Work process Foundation (WF)
Windows Presentation Foundation
Windows Correspondence Foundation (WCF)
LINQ

Mastermind and Execute VB.Net Program
If you are using Visual Studio.Net IDE, make the going with steps:
Start Visual Studio.
Wander  New  On the menu bar, pick Record
Pick Visual Basicfrom designs
Pick Console Application.
Show a name and zone for your endeavor using the Inquiry get, and a short time later pick the
okay catch.
The new pursuit appears in Game plan Voyager.
Create code in the Code Editor.
Click the Run get or the F5 key to run the endeavor. A Request Brief window gives contains the
line Hello there World.
You can total a VB.Net program by using the summon line instead of the Visual Studio IDE:
Open a substance supervisor and incorporate the previously stated code.
Save the record as helloworld.vb
Open the summon brief instrument and go to the file where you saved the record.
Sort vbc helloworld.vb and press enter to aggregate your code
If there are no slip-ups in your code the summon brief will take you to the accompanying line
and would create helloworld.exe executable record.
Next, sort helloworld to execute your venture.
You will have the ability to see "Hello there World" engraved on the screen

Delineation 1
In the going with delineation, let us incorporate a summary box at blueprint time and incorporate
things it at runtime.
Make the going with steps:
Move and tweak two names, a catch and a ListBox control on the structure.
Set the Substance property of the essential imprint to give the engraving "Pick your most adored
destination for higher studies".
Set the Substance property of the second name to give the engraving "Destination". The
substance on this imprint will change at runtime when the customer picks a thing on the
summary.
Click the listbox and the catch controls to incorporate the going with codes in the code
publication director.
Visual Basic .Net

At the point when the above code is executed and run utilizing Begin catch accessible at the
Microsoft Visual Studio instrument bar, it will demonstrate the accompanying window:

At the point when the client picks a destination, the content in the second name changes:

Example 2
For this situation, we will finish off an once-over box with things, recuperate the total number of
things in the summary box, sort the once-over box, empty a couple of things and clear the entire
once-over box. Plot the Structure:

At the point when the above code is executed and run utilizing Begin catch accessible at the
Microsoft Visual Studio instrument bar, it will demonstrate the accompanying window:
