These snippets show simple solutions to common problems, and simple recipes to help you implement new app features. Visual Basic is a powerful language that allows you to do many great things, also you can use the API functions for things that Visual Basic can't do, but it is not as powerful as Visual C. Visual C is a very big language that allows you to create any type of programs. You can create MS-DOS applications, Windows application, DLLs, etc. Every numeric data type in Visual Basic has a method that can be used to convert a string to that numeric data type. A) ConvertString B) FromString C) ToLiteral D) TryParse. are computer memory locations where programmers can temporarily store data while an application is running. A) Objects B) Variables C) Data types D) Classes. C# is ranked 9th while Visual Basic is ranked 61st. The most important reason people chose C# is: Where other languages invoke the feeling of being a product of organic growth over time, C# just feels like an incredibly well-designed language where everything has its purpose and almost nothing is non-essential.

Here we will learn the basics of visual basic (vb) programming language such as what is visual basic (vb), an overview of visual basic (vb) programming, features of visual basic (vb) programming and history of visual basic programming.
What is Visual Basic (VB)?
Visual Basic (VB) is a simple, modern, object-oriented and type-safe programming language. Visual Basic language has its roots from the family of C languages such as C, C++ and it is mostly similar to Java programming.
Visual Basic (VB) Programming language will allow developers to build a variety of secure and robust applications such as windows applications, web applications, database applications, etc. which will run on .NET Framework.
Visual Basic (VB) programming language has built on .NET Framework so to run the VB applications, we required to install a .NET Framework component on our machines.
.NET Framework is a development platform for building apps for windows, web, azure, etc. by using programming languages such as C#, F# and Visual Basic (VB). It consists of two major components such as Common Language Runtime (CLR), it’s an execution engine that handles running apps and .NET Framework Class Library, which provides a library of tested and reusable code that developers can use it in their applications.
Overview of Visual Basic (VB)
- Visual Basic (VB) is an object-oriented programming language and it supports the concepts of encapsulation, abstraction, polymorphism, etc.
- In VB all the variables, methods and application’s entry point are encapsulated within the class definitions.
- Visual Basic (VB) is developed specifically for .NET Framework and it enables programmers to migrate from C/C++ and Java easily.
- Visual Basic is a fully Event-driven and visual programming language.
- Microsoft provided an IDE (Integrated Development Environment) tool called Visual Studio to implement VB programs easily.
Features of Visual Basic (VB)
- Visual Basic (VB) contains various features that make it similar to other programming languages such as C, C++, and Java.
- VB is a modern programming language and it is very powerful, simple for building the applications
- Visual Basic (VB) is useful in developing windows, web and device applications.
- Visual Basic provides automatic memory management by clearing unused objects
- VB is a type-safe programming language and it makes impossible to perform unchecked type casts.
- VB provides a structured and extensible approach for error detection and recovery.
Visual Basic is a structure-oriented programming language and the compilation, execution of VB applications are faster due to automatic scalability.
History of Visual Basic (VB)
C++ Vs Visual Basic
The initial release of Visual Basic programming language is in 2002 with .NET Framework 1.0 and it’s more like Java programming. The latest version of Visual Basic is 15.8 and it was released with Visual Studio 2017 with a lot of new features.
1.1 The concept of computer programming
Programming means designing a set of instructions to instruct the computer to carry out certain jobs that are very much faster than human beings can do. The earliest programming language is called machine language which uses the binary code(comprises 0 and 1) to communicate with the computer. However, the machine language is extremely difficult to learn . Fortunately , scientists have invented some high-level programming languages that are much easier to master. Among the high-level programming languages are Java, Javascript, C, C++, c# and Visual Basic.

1.2 What is Visual Basic?
Visual Basic is a third-generation event-driven programming language first released by Microsoft in 1991. It evolved from the earlier DOS version called BASIC. BASIC means Beginners' All-purpose Symbolic Instruction Code. Since then Microsoft has released many versions of Visual Basic, from Visual Basic 1.0 to the final version Visual Basic 6.0. Visual Basic is a user-friendly programming language designed for beginners, and it enables anyone to develop GUI window applications easily.
In 2002, Microsoft released Visual Basic.NET(VB.NET) to replace Visual Basic 6. Thereafter, Microsoft declared VB6 a legacy programming language in 2008. Fortunately, Microsoft still provides some form of support for VB6. VB.NET is a fully object-oriented programming language implemented in the .NET Framework. It was created to cater for the development of the web as well as mobile applications. However, many developers still favor Visual Basic 6.0 over its successor Visual Basic.NET.
1.3 What programs can you create with Visual Basic 6?
In VB 6, you can create any program depending on your objective. For math teachers, you can create mathematical programs such as Geometric Progression, Quadratic Equation Solver, Simultaneous Equation Solver ,Prime Number Tester, Factors Finder, Quadratic Function Graph Plotter and so on. For science teachers, you can create simulation programs such as Projectile, Simple Harmonic Motion, Star War etc. If you are in business, you can also create business applications such as inventory management system , Amortization Calculator , investments calculator, point-of-sale system, payroll system, accounting program and more to help manage your business and increase productivity. For those of you who like games , you can create programs such as slot machine, reversi, tic tac toe and more. Besides, you can create multimedia programs such as Smart Audio Player, Multimedia Player and more. Indeed, there is no limit to what program you can create ! We offer many sample codes in our tutorial.
1.4 The Visual Basic 6 Integrated Development Environment
Before you can write programs in VB 6, you need to install Visual Basic 6 compiler on your computer. You can purchase a copy of Microsoft Visual Basic 6.0 Learning Edition or Microsoft Visual Basic Professional Edition from Amazon.com, both are vb6 compilers. Besides, you can also buy it from eBay at Microsoft Visual Basic 6.0 6 Professional PRO MSDN Library Manual Service Pack. If you have already installed Microsoft Office in your PC or laptop, you can also use the built-in Visual Basic Application in Excel to start creating Visual Basic programs without having to spend extra cash to buy the VB6 compiler.
101 Visual Basic And C# Code Samples List
You can also install VB6 on Windows 10 but you need to follow certain steps otherwise the installation will fail. First, you need to run setup as administrator. Next, you need to use custom installation. Clear the checkbox for Data Access. If you don't, set up will hang at the end of the installation. Finally, click next and wait for the installation to complete. For complete instructions, please follow this link Install VB6 on Windows 10
After installing the vb6 compiler, the icon will appear on your desktop or in your programs menu. Click on the icon to launch the VB6 compiler. On start up, Visual Basic 6.0 will display the following dialog box as shown in Figure 1.1.
You can choose to either start a new project, open an existing project or select a list of recently opened programs. A project is a collection of files that make up your application. There are various types of applications that we could create, however, we shall concentrate on creating Standard EXE programs (EXE means executable). Before you begin, you must think of an application that preferably have commercial ,educational or recreational value. Next, click on the Standard EXE icon to go into the actual Visual Basic 6 programming environment.
When you start a new Visual Basic 6 Standard EXE project, you will be presented with the Visual Basic 6 Integrated Development Environment (IDE). The Visual Basic 6 Integrated Programming Environment is shown in Figure 1.2. It consists of the toolbox, the form, the project explorer and the properties window.
How To Code Visual Basic
The Form is the primary building block of a Visual Basic 6 application. A Visual Basic 6 application can actually comprise many forms, but we shall focus on developing an application with one form first. We will learn how to develop applications with multiple forms later. Before you proceed to build the application, it is a good practice to save the project first. You can save the project by selecting Save Project from the File menu, assign a name to your project and save it in a certain folder. You shall now proceed to learn Visual Basic programming from the next lesson onwards.
