• Distinguish the Toolbox and summarize its function.
• Show and hide the Toolbox.
• Explain the concept of Objects.
• List the stages of writing a program.
• Start and stop the application they are designing.

Introduction to Programming

• Human life is full of tasks, many complex and repetitive, making it suited for computer automation
• Computers excel at performing repetitive tasks accurately and quickly
• Computers require explicit instructions to solve problems, hence the need for computer programming

What is a Program?

• A program is a set of instructions directing a computer to perform a specific task, such as a calculation
• Computers cannot act independently; they require precise instructions
• They execute given commands sequentially without deviation

Example: Calculating a Student's Grade

• An example is calculating a student's grade, which involves summing midterm and final exam scores

Steps

• Define the two grades (A for midterm, B for final).

• Define a storage location for the result (C).

• Write the calculation: C = A + B.

• The provided example is for a single student

• For a class of 500, repeating the steps becomes tedious, highlighting the benefit of programming

• The program automates the process, prompting for each student's grades and displaying results

Simplified Model:

• Print C (Display the result)
• C = A + B (Calculate the sum)
• Input A, B (Enter the two grades)

Project Structure in C#.NET

• In C#.NET, a program is called a "Project" as it may include multiple files, objects, and languages

Programmer

• The Programmer writes the instructions and commands, also known as a Developer

Programming Languages

• Different environments have different languages with their own grammar
• Computer programming requires using a programming language
• All languages consist of their own set of special commands and symbols
• All codes together make up what are called "Program codes"

Various languages

• There are various programming languages that include Visual Basic, C#, Delphi, Java and so on
• The language consists of commands in English
• Which allows programmers to be able to read commands clearly
• The programmer needs to learn and understand the commands, as well as language's syntax
• The synax is used to specify their meaning, and the syntactical roles

Advantages of NET environment

• Multiple languages can be used in the same program
• This allows the individual to take advantage of the characteristics of each language
• The program operates independently of the operating system
• This makes it work on various windows
• The program does not require translation to machine language on the used device

Concepts and language

• Various concepts are applied such as object-oriented programming(OOP)

Overview of C Sharp:

• C Sharp is also written as C#, and is also pronounced C sharp
• It is one of the languages supported by NET.
• The language combines the ease of using visual basics, and the power the the C++
• The C# has some concepts that resemble Java's and shares the benefits, and principles.

IDE (Integrated Development Environment)

• Consists of the tools and instructions used to create a design programs, and applications before NET, visual studio had its specific language it would correspond to
• NET languages have adopted the use of IDE (Integrated Development Environment), in this enivironment you can now simultaneously create applications in more than one language
• The Microsoft company has developed a large number of versions of C# for designing programs, they have also created several versions for languages such as Vb.NET, and C#

Instalation Of C Sharp

• install Express to install new C sharp programs
• Install by opening web browser. and visiting visualstudio.com/en-us/downloads#d-2010-express
• A number of links will be displayed, now click visual 2010 C#
• After the page redirects click the link install Now

Programming steps

• You will need to copy the information once registration is compelete

How to run development environment

• press windows button (start) then click all programs, then select the visual studio from micrsoft

Layout for display

• When the main menu is selected a page will be displayed

Layout of components

• The display panel has different component, by each section
• The different sections include create, close and so on
• Open projects can be found under open Project. If you would like to create a new project make sure to select the create project

Creating new sections

• Sections can be developed by the main page
• Click File for New Project

Selection page

• In this area a user can develop a variety of different projects, and software

List of different programming applications

• There are different types of selections avaliable
• The selections include things such Windows applications, or a Wpf program

Types of Programming;

• Windows applications: for the function with the Windows operation system, such as excel, calculator, and others
• Wpf application: used during web development so the programmer can have a easier access without going through direct contact to the internet

Basic program setup

• The next box the programmer has to choose from is the windows setup, it requires the form and name for for the selected projects

Layout introduction:

• The form is a window for the design, where the toolbox, properties, and solution explorer can be found

Toolbox overview:

• This section has commands for the project Solution explorer section:
• the project will be broken down into project's basic components, such the class lists

Layout properties

• This section will cover the different properties for the solution projects

Layout navigation:

• Each section will have an associated title, if you want to close the sections the cross bar

Display options:

• Each section can be seen on the bar, once connected it can be moved for easier navigation

Button operations

• Windowsform: opens once, it is an app for windows
• Console application: it creates simple applications, and avoids need for windows

Properties

• These functions are used when implementing the code, they appear on different components of the code

Features

• Features will provide you with different ways on how to change colors, add images

Operations and properties

• Can show different ways on setting it up

Toolbox tools

• The tool box shows the names of what's being applied to the project, for example clicking label, provides you short description

Title name overview

• Once you have connected and are planning to navigate, each corner will have a bar that tells you what the tool does
