All visual elements in the Windows Forms class library derive from the Control class. This provides the minimal functionality of a user interface element such as location, size, color, font, text, as well as common events like click and drag/drop. The Control class also has docking support to let a control rearrange its position under its parent. </p><p>Forms are typically designed in the <a href="/wiki/Visual_Studio" title="Visual Studio">Visual Studio</a> <a href="/wiki/Integrated_development_environment" title="Integrated development environment">IDE</a>. In Visual Studio, forms are created using <a href="/wiki/Drag-and-drop" class="mw-redirect" title="Drag-and-drop">drag-and-drop</a> techniques. A tool is used to place controls (e.g., text boxes, buttons, etc.) on the form (window). Controls have <a href="/wiki/Attribute_(computing)" title="Attribute (computing)">attributes</a> and <a href="/wiki/Event_handler" class="mw-redirect" title="Event handler">event handlers</a> associated with them. Default values are provided when the control is created, but may be changed by the programmer. Many attribute values can be modified during run time based on user actions or changes in the environment, providing a dynamic application. For example, code can be inserted into the form resize event handler to reposition a control so that it remains centered on the form, expands to fill up the form, etc. By inserting code into the event handler for a keypress in a text box, the program can automatically translate the case of the text being entered, or even prevent certain characters from being inserted. </p> <div class="mw-heading mw-heading2"><h2 id="Syntax">Syntax</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Visual_Basic_(.NET)&action=edit&section=2" title="Edit section: Syntax"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1251242444">.mw-parser-output .ambox{border:1px solid #a2a9b1;border-left:10px solid #36c;background-color:#fbfbfb;box-sizing:border-box}.mw-parser-output .ambox+link+.ambox,.mw-parser-output .ambox+link+style+.ambox,.mw-parser-output .ambox+link+link+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+style+.ambox,.mw-parser-output .ambox+.mw-empty-elt+link+link+.ambox{margin-top:-1px}html body.mediawiki .mw-parser-output .ambox.mbox-small-left{margin:4px 1em 4px 0;overflow:hidden;width:238px;border-collapse:collapse;font-size:88%;line-height:1.25em}.mw-parser-output .ambox-speedy{border-left:10px solid #b32424;background-color:#fee7e6}.mw-parser-output .ambox-delete{border-left:10px solid #b32424}.mw-parser-output .ambox-content{border-left:10px solid #f28500}.mw-parser-output .ambox-style{border-left:10px solid #fc3}.mw-parser-output .ambox-move{border-left:10px solid #9932cc}.mw-parser-output .ambox-protection{border-left:10px solid #a2a9b1}.mw-parser-output .ambox .mbox-text{border:none;padding:0.25em 0.5em;width:100%}.mw-parser-output .ambox .mbox-image{border:none;padding:2px 0 2px 0.5em;text-align:center}.mw-parser-output .ambox .mbox-imageright{border:none;padding:2px 0.5em 2px 0;text-align:center}.mw-parser-output .ambox .mbox-empty-cell{border:none;padding:0;width:1px}.mw-parser-output .ambox .mbox-image-div{width:52px}@media(min-width:720px){.mw-parser-output .ambox{margin:0 10%}}@media print{body.ns-0 .mw-parser-output .ambox{display:none!important}}</style><table class="box-Expand_section plainlinks metadata ambox mbox-small-left ambox-content" role="presentation"><tbody><tr><td class="mbox-image"><span typeof="mw:File"><a href="/wiki/File:Wiki_letter_w_cropped.svg" class="mw-file-description"><img alt="[icon]" src="//upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/20px-Wiki_letter_w_cropped.svg.png" decoding="async" width="20" height="14" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/30px-Wiki_letter_w_cropped.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/40px-Wiki_letter_w_cropped.svg.png 2x" data-file-width="44" data-file-height="31" /></a></span></td><td class="mbox-text"><div class="mbox-text-span">This section <b>needs expansion</b>.

The most common statement is an expression statement, consisting of an <a href="/wiki/Expression_(computer_science)" title="Expression (computer science)">expression</a> to be evaluated, on a single line. As part of that evaluation, <a href="/wiki/Subroutine" class="mw-redirect" title="Subroutine">functions or subroutines</a> may be <a href="/wiki/System_call" title="System call">called</a> and <a href="/wiki/Variable_(programming)" class="mw-redirect" title="Variable (programming)">variables</a> may be <a href="/wiki/Assignment_(computer_science)" title="Assignment (computer science)">assigned</a> new values. To modify the normal sequential execution of statements, Visual Basic provides several control-flow statements identified by reserved keywords. <a href="/wiki/Structured_programming" title="Structured programming">Structured programming</a> is supported by several constructs including two conditional execution constructs (<code>If</code> ... <code>Then</code> ... <code>Else</code> ... <code>End If</code> and <code>Select Case</code> ... <code>Case</code> ... <code>End Select</code> ) and four iterative execution (loop) constructs (<code>Do</code> ... <code>Loop</code>, <code>For</code> ... <code>To</code>, <code>For Each</code>, and <code>While</code> ... <code>End While</code>) . The <code>For</code> ... <code>To</code> statement has separate initialisation and testing sections, both of which must be present. (See examples below.) The <code>For Each</code> statement steps through each value in a list. </p><p>In addition, in Visual Basic: </p> <ul><li>There is no unified way of defining blocks of statements. Instead, certain keywords, such as "If … Then" or "Sub" are interpreted as starters of sub-blocks of code and have matching termination keywords such as "End If" or "End Sub".</li> <li>Statements are terminated either with a <a href="/wiki/Colon_(punctuation)" title="Colon (punctuation)">colon</a> (":") or with the <a href="/wiki/End_of_line" class="mw-redirect" title="End of line">end of line</a>. Multiple-line statements in Visual Basic are enabled with " _" at the end of each such line.

There are new additions to support new features, such as <a href="/wiki/Exception_handling" title="Exception handling">structured exception handling</a> 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> <a href="/wiki/Data_type" title="Data type">data type</a> has been doubled in length from 16 bits to 32 bits, and the <code>Long</code> <a href="/wiki/Data_type" title="Data type">data type</a> 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 <a href="/wiki/Windows_Forms" title="Windows Forms">Windows Forms</a> editor is very similar in style and function to the Visual Basic form editor. </p><p>The things that <i>have</i> changed significantly are the semantics—from those of an object-based programming language running on a <a href="/wiki/Deterministic" class="mw-redirect" title="Deterministic">deterministic</a>, <a href="/wiki/Reference_counting" title="Reference counting">reference-counted</a> engine based on <a href="/wiki/Component_Object_Model" title="Component Object Model">COM</a> to a fully <a href="/wiki/Object-oriented" class="mw-redirect" title="Object-oriented">object-oriented</a> language backed by the <a href="/wiki/.NET_Framework" title=".NET Framework">.NET Framework</a>, which consists of a combination of the <a href="/wiki/Common_Language_Runtime" title="Common Language Runtime">Common Language Runtime</a> (a <a href="/wiki/Virtual_machine" title="Virtual machine">virtual machine</a> using <a href="/wiki/Garbage_collection_(computer_science)#Generational_GC_(aka_Ephemeral_GC)" title="Garbage collection (computer science)">generational garbage collection</a> and a <a href="/wiki/Just-in-time_compilation" title="Just-in-time compilation">just-in-time compilation</a> engine) and a far larger <a href="/wiki/Class_library" class="mw-redirect" title="Class library">class library</a>. 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 <i>My</i> feature in Visual Studio 2005. </p><p>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 <a href="/wiki/Refactoring" class="mw-redirect" title="Refactoring">refactoring</a> to take full advantage of the new language. Documentation is available to cover changes in the syntax, debugging applications, deployment and terminology.<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Comparative_examples">Comparative examples</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Visual_Basic_(.NET)&action=edit&section=6" title="Edit section: Comparative examples"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The following simple examples compare VB and VB.NET syntax.

Some programmers prefer to do things "the .NET way", since the Framework classes have more features and are less language-specific. Others argue that using language-specific features makes code more readable (for example, using <code>int</code> (C#) or <code>Integer</code> (VB.NET) instead of <code>System.Int32</code>).</li> <li>In Visual Basic 2008, the inclusion of <code class="mw-highlight mw-highlight-lang-vbnet mw-content-ltr" style="" dir="ltr"><span class="k">ByVal</span><span class="w"> </span><span class="n">sender</span><span class="w"> </span><span class="ow">as</span><span class="w"> </span><span class="kt">Object</span></code>, <code class="mw-highlight mw-highlight-lang-vbnet mw-content-ltr" style="" dir="ltr"><span class="k">ByVal</span><span class="w"> </span><span class="n">e</span><span class="w"> </span><span class="ow">as</span><span class="w"> </span><span class="n">EventArgs</span></code> has become optional.</li></ul> <p>The following example demonstrates a difference between Visual Basic 6 and VB.NET.

Though C# and Visual Basic 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.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup> They compile to the same intermediate language (IL), which runs against the same .NET Framework runtime libraries.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> Although there are some differences in the programming constructs, their differences are primarily syntactic and, assuming one avoids the Visual Basic "Compatibility" libraries provided by Microsoft to aid conversion from Visual Basic 6, almost every feature in VB has an equivalent feature in C# and vice versa. 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. </p> <div class="mw-heading mw-heading2"><h2 id="Examples">Examples</h2><span class="mw-editsection"><span
