This document provides an overview of basic programming concepts and tools in Visual Studio. It discusses namespaces as containers that organize code and avoid naming conflicts. It also describes several Visual Studio tools like the Solution Explorer for managing solution files, Properties Editor for editing object properties, and Toolbox for adding controls to forms. Finally, it provides steps for creating a Windows Form application, adding controls, and debugging the application.

1. Basic Programming Overview
Session 4

2. Objective
• NameSpace
• Several Tools.
• Solution Explorer, Property Window & Toolbox
• Windows Form

3. Namespace
• A Namespace in Microsoft .NET is like
containers of objects.
• Main goal of using namespace in .NET is for
creating a hierarchical organization of program.
• In this case a developer does not need to worry
about the naming conflicts of classes, functions,
variables etc., inside a project.
• The advantage is that every namespace can
contain any number of classes, functions,
variables and also namespaces etc., whose names
are unique only inside the namespace.

4. Namespace(Example)
// Namespace Declaration
using System;
// User created Namespace
namespace hello
{
// Program start class
class space
{
// Main begins program execution.
public static void Main()
{
// Write to console
Console.WriteLine("This is the example of creating own
Namespace.");
}
}
}

5. Other Tools
There are numerous tools available in Visual
studio IDE. We will use the following..
• Properties Editor
• Solution Explorer
• Toolbox

6. Properties Editor
• The Properties Editor tool is used to edit
properties in a GUI pane inside Visual Studio.
• It lists all available properties (both read-only
and those which can be set) for all objects
including forms, web pages and other items.

8. Solution Explorer
• In Visual Studio , a solution is a set of code
files and other resources that are used to build
an application. The files in a solution are
arranged hierarchically, which might or might
not reflect the organization in the file system.
• The Solution Explorer is used to manage and
browse the files in a solution.

10. Toolbox
• Visual Studio provides a Toolbox which can
be used to add numerous controls to a
Windows Form or a Web Form.
• On the Design pane we can add those controls
by selecting and dragging the desired control.

12. Creating a Windows Form Application
• To create a Windows Form Application we
have to click on File-New-Project or simply
Ctrl+Shift+N from the keyboard.
• The ‘New Project’ window will appear.
• On the ‘New Project’ window we have to
select the ‘Windows Form Application’ and
click ‘Ok’.

14. • A new design window will open. It will be
look like this…

16. • On the design window we can add any
Controls from the toolbox.
• Here I have taken the Button and the TextBox
Control.

18. • After that we have to write code for the
Windows Form application.

20. Debugging the Windows Form
Application

21. Summery
• Several Tools.
• Namespace.
• Hands on knowledge on Visual Studio IDE.
• Creating Windows Form Application.
