'''Visual Basic''' ('''VB'''), originally called '''Visual Basic .NET''' ('''VB.NET'''), is a [[Multi-paradigm programming language|multi-paradigm]], [[Object-oriented programming|object-oriented]] [[programming language]]
Microsoft's [[integrated development environment]] (IDE) for developing in Visual Basic is [[Visual Studio]]. Most Visual Studio editions are [[commercial software|commercial]]; the only exceptions are [[Visual Studio Express]] and [[Microsoft Visual Studio#Community|Visual Studio Community]], which are [[freeware]]. In addition, the [[.NET Framework SDK]] includes a freeware [[command-line]] [[compiler]] called vbc.exe. [[Mono (software)|Mono]] also includes a command-line VB.NET compiler.
Line 43:
In addition, in Visual Basic:
* There is no unified way of defining blocks of statements. Instead, certain keywords, such as "If
* Statements are terminated either with a [[Colon (punctuation)|colon]] (":") or with the [[end of line]]. Multiple-line statements in Visual Basic are enabled with " _" at the end of each such line. The need for the underscore continuation character was largely removed in version 10 and later versions.<ref>{{cite web |url=https://msdn.microsoft.com/en-us/library/ff637436.aspx |title=New Features in Visual Basic 10 |date=June 3, 2010 |access-date=September 5, 2015 |archive-date=March 4, 2016 |archive-url=https://web.archive.org/web/20160304231731/https://msdn.microsoft.com/en-us/library/ff637436.aspx |url-status=live }}</ref>
* The [[equals sign]] ("=") is used in both assigning values to variables and in comparison.
Line 131:
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 [[exception handling|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 <code>Integer</code> [[data type]] has been doubled in length from 16 bits to 32 bits, and the <code>Long</code> [[data type]] has been doubled in length from 32 bits to 64 bits. This is true for all versions of VB.NET. A 16-bit integer in all versions of VB.NET is now known as a <code>Short</code>. 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 counting|reference-counted]] engine based on [[Component Object Model|COM]] to a fully [[Object-oriented programming|object-oriented]] language backed by the [[.NET Framework]], which consists of a combination of the [[Common Language Runtime]] (a [[virtual machine]] using [[Garbage collection (computer science)#Generational GC (aka Ephemeral GC)|generational garbage collection]] and a [[just-in-time compilation]] engine) and a far larger [[class library]]. The increased breadth of the latter

=== 2003 (VB 7.1) ===
Visual Basic .NET 2003 was released with [[.NET Framework 1.1]]. New features included support for the [[.NET Compact Framework]] and a better VB upgrade [[wizard (software)|wizard]]. Improvements were also made to the performance and reliability of .NET IDE (particularly the [http://msdn.microsoft.com/msdnmag/issues/05/06/AdvancedBasics/default.aspx background compiler]) and runtime. In addition, Visual Basic .NET 2003 was available in the Visual Studio.NET Academic Edition, distributed to a certain number of scholars
