Basic Programming Overview

Session 4

Objective

• NameSpace

• Several Tools.

• Solution Explorer, Property Window & Toolbox

• Windows Form

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.

Namespace(Example) // Namespace Declaration

using System;

// User created Namespacenamespace 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.");         }    }}

Other Tools

There are numerous tools available in Visual studio IDE. We will use the following..

• Properties Editor

• Solution Explorer

• Toolbox

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.

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.

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.

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’.

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

• On the design window we can add any Controls from the toolbox.

• Here I have taken the Button and the TextBox Control.

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

Debugging the Windows Form Application

Summery

• Several Tools.

• Namespace.

• Hands on knowledge on Visual Studio IDE.

• Creating Windows Form Application.
