Visual Basic . NET - Wikipedia. Visual Basic . Microsoft launched VB. NET in 2. 00. 2 as the successor to its original Visual Basic language. Along with Visual C#, it is one of the two main languages targeting the . NET framework. Microsoft's integrated development environment (IDE) for developing in Visual Basic . NET language is Visual Studio. Most of Visual Studio editions are commercial; the only exceptions are Visual Studio Express and Visual Studio Community, which are freeware. In addition, . NET Framework SDK includes a freeware command- linecompiler called vbc. Mono also includes a command- line VB. NET compiler. VB. 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 . End Select ) and three iterative execution (loop) constructs (Do . Instead, certain keywords, such as . Multiple line statements in Visual Basic . NET are enabled with . The need for the underscore continuation character was largely removed in version 1. Visual Basic . NET uses round brackets to define the parameters of subroutines or functions. A single quotation mark ('), placed at the beginning of a line or after any number of space or tab characters at the beginning of a line, or after other code on a line, indicates that the (remainder of the) line is a comment. Simple example. Each line serves a specific purpose, as follows: This is a module definition, a division of code similar to a class, although modules can contain classes. Modules serve as containers of code that can be referenced from other parts of a program. Console is a system object, representing a command- line interface (also known as . The program calls the Console method Write. Line, which causes the string passed to it to be displayed on the console. Instead of Console. Write. Line, one could use Msg. Box, which prints the message in a dialog box instead of a command- line window. 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 Integerdata type has been doubled in length from 1. Longdata type has been doubled in length from 3. This is true for all versions of VB. NET. A 1. 6- 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. 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 2. The changes have altered many underlying assumptions about the . Some functions and libraries no longer exist; others are available, but not as efficient as the . 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. 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 . Visual Basic . NET will also generate the necessary Class and End Class statements. The developer need only add the statement to display the . However, these are default names for a command button in Visual Basic 6 and VB. NET respectively. In VB. NET, the Handles keyword is used to make the sub Button. In Visual Basic 6, event handler subs must have a specific name consisting of the object's name (. There is a controversy. Some programmers prefer to do things . Others argue that using language- specific features makes code more readable (for example, using int (C#) or Integer (VB. NET) instead of System. Int. 32). In Visual Basic 2. By. Val sender as Object, By. Val e as Event. Args has become optional. The following example demonstrates a difference between Visual Basic 6 and VB. NET. Both examples close the active window. Visual Basic 6: Subcmd. Close. The following are equivalent: Visual Basic 6: Sub. Timer. 1. 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. 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. Examples. The most important feature is managed code, which contrasts with the classic Visual Basic. VB 7. 1). New features included support for the . NET Compact Framework and a better VB upgrade wizard. Improvements were also made to the performance and reliability of . NET IDE (particularly the background compiler) and runtime. In addition, Visual Basic . NET 2. 00. 3 was available in the Visual Studio. NET Academic Edition, distributed to a certain number of scholars. My. Forms)Improved VB- to- VB. NET converter. Microsoft had planned to use Dynamic Language Runtime (DLR) for that release. Visual Basic's innate ability to interact dynamically with CLR and COM objects has been enhanced to work with dynamic languages built on the DLR such as Iron. Python and Iron. Ruby. 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.
