Visual Basic VB.NET Tutorial for Beginners
VB.NET is a simple, object-oriented programming language that can be used to make a wide range of Windows, Web, and mobile apps that run on the .NET Framework. It supports multiple programming paradigms. Our VB.NET tutorial covers all the fundamental and advanced concepts of VB.NET, including forms, buttons, events, strings, arrays, program flow control, file and exception handling, and much more.
What is the VB.NET language?
Visual Basic is the abbreviation for VB.NET. Technologies that enable networks. It was created by Microsoft in 2002 and is a straightforward, high-level, object-oriented programming language. The Microsoft .NET framework is used to develop this Visual Basic 6.0 replacement. Additionally, it supports OOPs concepts like polymorphism, inheritance, encapsulation, and abstraction. Any fundamental data types (such as Integer, String, Char, Long, Short, Boolean, etc.), user-defined data types, events, and all objects that derive from its parent class are all objects in the VB.NET programming language. While C++, Java, and C# are case-sensitive languages, this language does not.
Applications created in the VB.NET programming language are extremely dependable and scalable since they rely on the .NET Framework to obtain all libraries necessary for VB.NET program execution. You may construct a completely object-oriented program using this language that is comparable to an application made using another language like C++, Java, or C#. Additionally, apps and programs written in VB.NET may operate on Linux and Mac OS in addition to Windows.
Any new programmer, regardless of experience level, may easily create a straightforward, safe, reliable, high-performance web, windows, console, or mobile application that runs on the .NET Framework using the VB.NET language.
VB.NET Functionality
As we all know, it is a high-level programming language with a lot of features that can be used to make a safe and reliable app. It is the most popular programming language because of the following things.
- It is an object-oriented programming language that uses concepts like abstraction, encapsulation, inheritance, and many others. It means that everything will be treated as an object in VB.NET programming.
- This language is used to make user interfaces for apps that run on Windows, mobile devices, and the web.
- It works with a toolkit for making apps quickly. In which a developer doesn't have to write all of the code because it can get code from its libraries automatically. For example, when we create a form in Visual Basic.net, it automatically calls the events of different forms in that class.
- It doesn't care about case like C++, Java, and other languages do.
- It lets programmers use Boolean conditions to decide what to do.
- It also works with the idea of multithreading, which means that you can do more than one thing at the same time.
- It makes it easy to handle events in.NET applications.
- With a Window Form, we can use all of the functionality of an existing form to make a new form. In this way, it made the code easier to understand.
- It uses a reference to an outside object that a VB.NET program can use.
- A garbage collection was started up automatically.
- It uses a structured programming language that can be expanded to find and fix errors.
- Generic classes that are easy to use and can be built based on conditions.
- It can be used to make apps for the web, Windows, and mobile devices.
VB.NET Advantages
- VB.NET runs a program so that it runs under CLR (Common Language Runtime). This makes an application that is strong, stable, and safe.
- It is a pure object-oriented programming language that uses objects and classes as its building blocks. But the older version of Visual Basic 6 doesn't have these features. Because of this, Microsoft created the VB.NET language.
- By using the Visual Studio Integrated Development Environment (IDE), you can make a small program that works faster, as well as a large desktop and web application.
- The.NET Framework is a piece of software that has a large number of libraries that help make applications that work better.
- It makes web forms in.NET applications by letting you drop and drag elements.
- But Visual Basic.NET lets you connect two programs written in the same language so that they can both run on the.NET framework.
- Your code can be automatically set up by VB.NET.
- The Visual Basic.NET programming language is also used to send simple text strings of data between different layers of the.NET architecture.
- It uses a new way of thinking about how to deal with errors in the Visual Basic.NET Framework. The try, catch, and finally method is the new way to handle exceptions as a whole. Also, it lets the right thing be done at the spot where it ran into a problem. In this way, it makes it less likely for.NET programmers to use the ON ERROR GOTO statement.
VB.NET disadvantages
- Pointers cannot be handled directly by the VB.NET programming language. Because managing every address with a pointer in this language is difficult and needs a lot of code. Additionally, more code uses more CPU cycles, which extends the processing time. It demonstrates how sluggish the VB.NET program is.
- Because VB.NET programming is simple to understand, there is more rivalry among programmers to compete for the same job or project in VB.NET. As a result, it makes it harder to get a stable employment as a VB.NET developer.
- There is nothing that can stop a program from dissolving; it employs an Intermediate Language (IL) compiler that is readily decompiled (reverse engineered).
- JIT (Just-In-Time) compiler It is necessary to run your program and is the method by which a computer can understand IL (intermediate language) compilation. It signifies that a JIT compiler is required on the destination computer in order to understand an IL source program, and that this additional CPU cycle used for interpretation reduces an application's performance.
- It includes a sizable number of libraries for the JIT compiler, which aids in the interpretation of an application. These huge libraries take up a lot of room in our system and need extra processing time.
