Overview

2. What ARE Visual Basic, .NET & VISUAL STUDIO
Overview
What ARE Visual Basic, .NET & VISUAL STUDIO

3. What is Visual Basic
Visual Basic is an object-oriented programming language
Objects are units of code, created from pre-built “master copies” of code, called Classes
Classes are stored in a library file called the .NET FRAMEWORK
The .NET framework is built into the editor, Visual Studio
Visual Studio is a robust framework, in that it integrates other tools into it, such as a database interface, hence it is called an Integrated Development Environment (IDE)

4. Overview
Programming

5. Programming Languages
Visual Basic
Programming language that allows developers to easily build complex Windows and Web programs, as well as other software tools
Based on the BASIC language
C++
Derivative of the programming language, C
Visual C#
Synthesis of the elegance and syntax of C++ with many of the productivity benefits enjoyed in Visual Basic
JavaScript
Open source client-side scripting language
Visual F#
Multipurpose language known for its math-intensive focus

6. Programming Overview
A program is a set of instructions that directs a computer to A perform task
A computer program on a mobile device or Windows 8/10 computer is also called an app

7. Programming Overview
In order for the computer to execute a program, hardware gets involved:
Program and data must be placed in the computer’s random access memory (RAM)
The central processing unit (CPU) can access the program instructions and the data in RAM to perform activities as directed by the program

8. Programming Overview The basic function of many programs is to:
accept some form of data (sometimes called input data)
manipulate the data in some manner (sometimes called processing)
create some form of data usable by people or other computers (sometimes called output data or information)

9. Programming Overview
Saving, or storing, data refers to placing the data or software electronically on a storage medium
Hard disk
Universal Serial Bus (USB) drive

10. Types of Visual Basic Applications
Windows application
Program will run on a computer or other device that supports the Windows GUI
Windows Store app
Designed to run on Windows 8/10 computers and mobile devices
Web application
Uses ASP.NET 4.6 and runs on a Web server

11. Programming Overview Computer Programs: Programming:
Programs are the step-by-step instructions that tell a computer how to perform a task
Each program statement causes the computer to perform one or more operations
The developer must follow the syntax, or programming rules, of the programming language precisely
Programming:
Writing programs - giving a mechanism the directions to accomplish a task
Programmers/developers:
people skilled in designing computer programs and creating them using programming languages
Programming languages:
code used to communicate with the computer
Applications:
may consist of several computer programs working together to solve a problem

12. Microsoft Intermediate Language (MSIL) and Common Language Runtime (CLR)
Program compilation translates programming statements into instructions that can be understood by the computer
Program compilation for a Visual Basic program creates a set of electronic code expressed in an intermediate language called the MicroSoft Intermediate Language (MSIL)
When the program is executed, a portion of .NET 4.6 called the Common Language Runtime (CLR) reads the MSIL and causes the actual instructions within the program to be executed

13. Microsoft Intermediate Language (MSIL) and Common Language Runtime (CLR)

14. .NET FRAMEWORK – VB.NET, ADO.NET, ASP.NET

15. .NET Framework 4.6
The .NET Framework provides tools and processes developers can use to produce and run programs
Most recent version is .NET Framework 4.6
Consists of Classes - A class is a named group of program code
A button is an example of a class
A Class library stores the Class and makes the class available to all developers who need to use it

16. .NET Class Library
An object is created from a class and is sometimes called an instance of a class
The process of creating an object from its Class is called instantiation
Rapid application development (RAD) refers to the process of using pre-built classes to make application development faster, easier, and more reliable
.NET Framework’s Class Library is known as System. It is broken down into smaller libraries called namespaces.
Each namespace holds the class code for similar groups of classes (windows forms, web forms, etc.)

17. ADO.NET 4.6
ADO.NET 4.6 (ActiveX Data Objects) provides the functionality for a program to perform four primary tasks when working with a database:
Get the data
Examine the data
Edit the data
Update the data

18. ASP.NET 4.6
Allows developers to use Visual Studio to build powerful, sophisticated Web applications
Easy to deploy a Web application on a Web server

19. VISUAL STUDIO

20. Visual Basic and Visual Studio
Most developers use a tool called Visual Studio to write Visual Basic programs
Visual Studio is a type of integrated development environment (IDE)
Provides services and tools that enable a developer to code, test, and implement a single program or series of programs

21. Visual Basic and Visual Studio
Contains many different windows, most frequently used are:
Designer, Toolbox, Properties, Solution Explorer

22. Visual Studio
Each tool shown in the window is derived from a Class in a particular namespace.
Clicking a tool, and dragging it onto the designer window creates the object (copies the class code into your program)
Each object has a set of attributes, called properties, that determine its behavior and appearance.
Properties are listed in the Properties window, and can be modified

23. Programming as a Profession

24. The Programmer’s Job Typical tasks performed by a programmer include:
Meet with users to determine the exact problem and to agree on the desired solution
Plan an appropriate solution and convert the solution to instructions that the computer can follow
Coding: the process of translating the solution into a programming language
Meet with users to determine whether the program fulfills the users’ needs
Rigorously test the program with sample data before releasing it to the user
Provide the user with a manual that explains how to use the program

25. Employment Opportunities
Job titles and descriptions vary
Software developers
Responsible for designing an appropriate solution to a problem
Computer programmers
Responsible for translating the solution into a language that the computer can understand
Competition for programming and software developer jobs
Jobseekers need to keep up to date with the latest programming languages and technologies
A competitive edge may be gained by obtaining vendor-specific and/or language-specific certifications
