NET]" to refer to all Visual Basic languages released since , in order to distinguish between them and the classic Visual Basic. Along with Visual C , it is one of the two main languages targeting the. NET framework. NET language is Visual Studio. In addition, the. Mono also includes a command-line VB. NET compiler. NET uses statements to specify actions. The most common statement is an expression statement, consisting of an expression to be evaluated, on a single line.
As part of that evaluation, functions or subroutines may be called and variables may be assigned new values. To modify the normal sequential execution of statements, VB. NET provides several control-flow statements identified by reserved keywords. Structured programming is supported by several constructs including two conditional execution constructs If … Then … Else … End If and Select Case The For … To statement has separate initialisation and testing sections, both of which must be present.
See examples below. The For Each statement steps through each value in a list. The following is a very simple VB. NET program, a version of the classic " Hello world " example created as a console application:.
It prints " Hello, world! Each line serves a specific purpose, as follows:. This is a module definition. Modules are a division of code, which can contain any kind of object, like constants or variables, functions or methods, or classes, but can't be instantiated as objects like classes and cannot inherit from other modules. Modules serve as containers of code that can be referenced from other parts of a program. It defines a subroutine called "Main". This line performs the actual task of writing the output.

Console is a system object, representing a command-line interface also known as "console" and granting programmatic access to the operating system's standard streams. The program calls the Console method WriteLine, which causes the string passed to it to be displayed on the console. Instead of Console. WriteLine, one could use MsgBox, which prints the message in a dialog box instead of a command-line window. This piece of code outputs Floyd's Triangle to the console:. Whether Visual Basic. NET should be considered as just another version of Visual Basic or a completely different language is a topic of debate.
There are new additions to support new features, such as structured exception handling and short-circuited expressions. Also, two important data-type changes occurred with the move to VB. NET: compared to Visual Basic 6, the Integer data type has been doubled in length from 16 bits to 32 bits, and the Long data type has been doubled in length from 32 bits to 64 bits.
This is true for all versions of VB. A bit integer in all versions of VB. NET is now known as a Short. Similarly, the Windows Forms editor is very similar in style and function to the Visual Basic form editor. The things that have changed significantly are the semantics—from those of an object-based programming language running on a deterministic , reference-counted engine based on COM to a fully object-oriented language backed by the.
NET Framework , which consists of a combination of the Common Language Runtime a virtual machine using generational garbage collection and a just-in-time compilation engine and a far larger class library. The increased breadth of the latter is also a problem that VB developers have to deal with when coming to the language, although this is somewhat addressed by the My feature in Visual Studio The changes have altered many underlying assumptions about the "right" thing to do with respect to performance and maintainability.
Some functions and libraries no longer exist; others are available, but not as efficient as the "native". NET alternatives. Even if they compile, most converted Visual Basic 6 applications will require some level of refactoring to take full advantage of the new language. Documentation is available to cover changes in the syntax, debugging applications, deployment and terminology. The following simple examples compare VB and VB. NET syntax. They assume that the developer has created a form, placed a button on it and has associated the subroutines demonstrated in each example with the click event handler of the mentioned button.
Each example creates a "Hello, World" message box after the button on the form is clicked. The following example demonstrates a difference between Visual Basic 6 and VB. Both examples close the active window. The 'cmd' prefix is replaced by the 'btn' prefix, conforming to the new convention previously mentioned. C and Visual Basic. NET are Microsoft's first languages made to program on the. NET Framework later adding F and more and others have also added languages. Though C and VB. NET are syntactically different, that is where the differences mostly end. Microsoft developed both of these languages to be part of the same.
NET Framework development platform. They are both developed, managed, and supported by the same language development team at Microsoft. NET Framework runtime libraries.

Lastly, both languages reference the same Base Classes of the. NET Framework to extend their functionality. As a result, with few exceptions, a program written in either language can be run through a simple syntax converter to translate to the other. There are many open source and commercially available products for this task.
Succeeding the classic Visual Basic version 6. NET debuted in As of [update] , eight versions of Visual Basic. NET are released. The first version, Visual Basic. NET, relies on. NET Framework 1.smarthydro.com/software-to-spy-on-messenger.php

The most important feature is managed code , which contrasts with the classic Visual Basic. NET was released with. New features included support for the. Improvements were also made to the performance and reliability of. In addition, Visual Basic. NET was available in the Visual Studio. After Visual Basic. NET , Microsoft dropped ". NET" from the name of the product, calling the next version Visual Basic For this release, Microsoft added many features intended to reinforce Visual Basic.
NET's focus as a rapid application development platform and further differentiate it from C.
It gained notoriety  when it was found to be the subject of a Microsoft patent application. Visual Basic 9. NET Framework 3. In April , Microsoft released Visual Basic Microsoft had planned to use Dynamic Language Runtime DLR for that release  but shifted to a co-evolution strategy between Visual Basic and sister language C to bring both languages into closer parity with one another.

Also, existing support of inline Functions was complemented with support for inline Subs as well as multi-line versions of both Sub and Function lambdas. Visual Basic was released along. NET Framework 4. Major features introduced in this version include: [ further explanation needed ].
