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.

Application

21. Summery
