This document discusses the basic concepts of VB.net programming including program structure, data types, operators, and how to compile and execute a VB.net program. It explains that a VB.net program consists of namespaces, classes, modules, procedures, variables, and the main procedure. It provides a simple "Hello World" example program and steps to create a new project, write code, and run the program in Visual Studio. Finally, it outlines various data types and operator types available in VB.net like arithmetic, relational, logical, and assignment operators.

2. VB.Net - Program Structure
VB.Net Hello World Example
A VB.Net program basically consists of the
following parts:
 Namespace declaration
 A class or module
 One or more procedures
 Variables
 The Main procedure
 Statements & Expressions
 Comments

3. Basic Program Example
1. Imports System
2. Module Module1
3. 'This program will display Hello World
4. Sub Main()
5. Console.WriteLine("Hello World")
6. Console.ReadKey()
7. End Sub
8. End Module

4. Compile & Execute VB.Net Program
 Start Visual Studio.
 On the menu bar, choose File → New → Project.
 Choose Visual Basic from templates
 Choose Console Application.
 Specify a name and location for your project
using the Browse button, and then choose the
OK button.
 The new project appears in Solution Explorer.
 Write code in the Code Editor.
 Click the Run button or the F5 key to run the
project. A Command Prompt window appears
that contains the line Hello World.

7. Operators
 An operator is a symbol that tells the compiler to perform
specific mathematical or logical manipulations. C++ is rich in
built-in operators and provide the following types of
operators −
 Arithmetic Operators
 Relational Operators
 Logical Operators
 Assignment Operators
