Visual Studio and .NET Framework Glossary
This glossary defines key terms of Visual Studio 2008 and the .NET Framework.
.NET Compact Framework
A hardware-independent environment for running programs on resource-constrained computing devices. It inherits the full .NET Framework architecture of the common language runtime, supports a subset of the .NET Framework class library, and contains classes designed exclusively for the .NET Compact Framework. Supported devices include personal data assistants (PDAs) (such as the Pocket PC), mobile phones, set-top boxes, automotive computing devices, and custom-designed embedded devices built with the Microsoft Windows CE.NET operating system.
An integral Windows component that supports building, deploying, and running the next generation of applications and Web services. It provides a highly productive, standards-based, multilanguage environment for integrating existing investments with next generation applications and services, as well as the agility to solve the challenges of deployment and operation of Internet-scale applications. The .NET Framework consists of three main parts: the common language runtime, a hierarchical set of unified class libraries, and a componentized version of ASP called ASP.NET. See also: ASP.NET, common language runtime, .NET Framework class library.
.NET Framework class library
A library of classes, interfaces, and value types that are included in the .NET Framework SDK. This library provides access to system functionality and is designed to be the foundation on which .NET Framework applications, components, and controls are built. See also: class, CLS-compliant, Common Language Specification, interface, value type.
.NET Framework data provider
A component of ADO.NET that provides access to data from a relational data source. A .NET Framework data provider contains classes to connect to a data source, execute commands at the data source, and return query results from the data source, including the ability to execute commands within transactions. A .NET Framework data provider also contains classes to populate a DataSet with results from a data source and propagate changes in a DataSet back to the data source.
A resource editor that allows you to add, delete, change, or browse the shortcut key assignments for your project.
access control list (ACL)
A list that specifies the rules for access to a particular resource. Microsoft Windows NT implements user-based ACLs, which specify the resources available to a particular user.
A customizable document-level task pane in Microsoft Office Word and Microsoft Office Excel.
Active Template Library
A collection of C++ templates to help users create Component Object Model (COM) objects.
A control, such as a check box or button that offers options to users or runs macros or scripts that automate a task. You can write macros for the control in Microsoft Visual Basic for Applications or scripts in Microsoft Script Editor.
In the .NET Framework add-in programming model, the add-in application assembly that communicates with a host application over a communication pipeline. See also: host, pipeline.
In the .NET Framework add-in programming model, an assembly that contains interfaces or abstract base classes, and represents the add-in's view of the methods and types used to communicate with a host. See also: add-in, host.
In the .NET Framework add-in programming model, an assembly that contains one or more classes, and converts data to and from the add-in view and the contract. Depending on the direction of the call, the adapter is either converting from a view to a contract or from a contract to a view. See also: add-in, contract.
The suite of data access technologies included in the .NET Framework class libraries that provide access to relational data and XML. ADO.NET consists of classes that make up the DataSet (such as tables, rows, columns, relations, and so on), .NET Framework data providers, and custom type definitions (such as SqlTypes for SQL Server).
A special glyph on the design surface. Adorners are usually attached to a target control, and they give the user a graphical means of adjusting the control's properties.
A function called by MFC applications after they explicitly linked to a DLL module when that module is no longer needed. This function decrements the module's reference count and, if the reference count is zero, unmaps it from the address space of the process.
A library that is used by MFC applications when linking to an extension DLL.
In WMI, a type of event that is generated after a series of events of another type have occurred. An aggregate event is used to represent a series of events to avoid flooding the event consumer. See also: event, event consumer.
In GDI+, the portion of pixel color data reserved for transparency information.
The way of determining the edges of a parent control to which a control is bound and how a control is resized with its parent. Anchoring and docking are mutually exclusive. See also: docking.
A code block that is passed as a parameter to a delegate.
A class type whose name is generated by the compiler and that inherits directly from Object. Members of an anonymous type are properties that are inferred from the object initializer that creates instances of the type.
The directory where the .exe file that loads into the initial or default application domain is located. If you create your own application domain, the application base is the location you specify in the AppDomainSetup class. See also: application domain.
application domain (AppDomain)
A boundary that the common language runtime establishes around objects created within the same application scope (that is, anywhere along the sequence of object activations beginning with the application entry point). Application domains help isolate objects created in one application from those created in other applications so that run-time behavior is predictable. Multiple application domains can exist in a single process.
The file used in ClickOnce applications that describes the application and all of its constituent files.
In ASP.NET, built-in functionality for common application tasks. ASP.NET includes application services for authentication (ASP.NET membership), persistent per-user information (profile properties), and more.
In ASP.NET, a variable store that is created on the server for the current application and is shared by all users. Application state is typically used to store information that is used for all users, such as application-wide settings.
A supplemental program that modifies or adds functionality to an existing program or application. The modifications are available to the application at all times.
A set of technologies in the Microsoft .NET Framework for building Web applications and Web services. ASP.NET pages execute on the server and generate markup (such as HTML, WML, or XML) that is sent to a desktop or mobile browser. ASP.NET pages use a compiled, event-driven programming model that improves performance and enables the separation of application logic and user interface. ASP.NET pages and Web services files created using ASP.NET contain server-side (rather than client-side) logic written in Visual Basic, C#, or any .NET-compatible language. Web applications and Web services take advantage of the features of the common language runtime, such as type safety, inheritance, language interoperability, versioning, and integrated security.
ASP.NET application services database
In ASP.NET, a database that stores the data for several ASP.NET application services, including membership, Web Parts personalization, roles, and profiles. The database can be a local database in the Web site's App_Data folder or a SQL Server or other database, depending on how the site is configured.
ASP.NET mobile controls
A set of ASP.NET controls designed for mobile Web applications. ASP.NET mobile controls extend their ASP.NET server control counterparts.
ASP.NET mobile Web Forms
Extensions to ASP.NET Web Forms that target mobile devices from cell phones to Pocket PCs.
A component of an ASP.NET application.
ASP.NET server control
A server-side component that encapsulates user interface and related functionality. An ASP.NET server control derives directly or indirectly from the System.Web.UI.Control class. The superset of ASP.NET server controls includes Web server controls, HTML server controls, and ASP.NET mobile controls. The page syntax for an ASP.NET server control includes a runat="server" attribute on the control's tag. See also: HTML server control, validation server controls, Web server control.
ASP.NET Web application
An application that processes HTTP requests (Web requests) and executes on top of ASP.NET. An ASP.NET Web application can include ASP.NET pages, Web services, HTTP handlers, and HTTP modules.
A collection of one or more files that are versioned and deployed as a unit. An assembly is the primary building block of a .NET Framework application. All managed types and resources are contained within an assembly and are marked either as accessible only within the assembly or as accessible from code in other assemblies. Assemblies also play a key role in security. The code access security system uses information about the assembly to determine the set of permissions that code in the assembly is granted. See also: private assembly, shared assembly.
A code cache used for side-by-side storage of assemblies. There are two parts to the cache: the global assembly cache contains assemblies that are explicitly installed to be shared among many applications on the computer; the download cache stores code downloaded from Internet or intranet sites, isolated to the application that caused the download so that code downloaded on behalf of one application or page does not impact other applications. See also: global assembly cache.
An integral part of every assembly that renders the assembly self-describing. The assembly manifest contains the assembly's metadata. The manifest establishes the assembly identity, specifies the files that make up the assembly implementation, specifies the types and resources that make up the assembly, itemizes the compile-time dependencies on other assemblies, and specifies the set of permissions required for the assembly to run properly. This information is used at run time to resolve references, enforce version binding policy, and validate the integrity of loaded assemblies. The self-describing nature of assemblies also helps makes zero-impact install and XCOPY deployment feasible. See also: assembly, metadata.
See other term: assembly manifest
In .NET Framework security, helps to make sure that a method has access to a particular resource even if the method's callers do not have the required permission. During a stack walk, if a stack frame asserting the required permission is encountered, a security check for that permission will succeed. Assertions can create security holes and should be used only with extreme caution.
In the ADO.NET Entity Framework, the definition of a relationship between entity types.
In WMI, a class that describes a relationship between two classes or between instances of two classes. The properties of an association class include pointers, or references, to the two classes or instances. The Association qualifier is attached to every association class for identification.
In Class Designer, a line that shows that two types are related. The line represents a field or property and leads from the type that contains the member to the field or property's type.
In the ADO.NET Entity Framework, a logical container for instances of associations of the same type.
A WMI Query Language statement that supports the traversal of associations programmatically by retrieving all endpoint instances that are associated with a particular source instance. See also: GROUP, HAVING, ISA, REFERENCES OF, SELECT, WHERE, WITHIN.
asynchronous communication layer
In ASP.NET, the layer of AJAX functionality that takes care of communication between the browser and the server.
A method call that returns to the caller immediately regardless of whether processing has completed. The results of processing are returned through another call on another thread. Asynchronous methods free the caller from having to wait until processing has finished. See also: semisynchronous method.
In ASP.NET, the process of sending Web page data (plus viewstate and other necessary metadata) from the browser to the server without a complete postback and without blocking the user from continuing to work in the page. Asynchronous postbacks are an important feature of AJAX technology.
See other term: Active Template Library
A descriptive declaration that can be applied to programming elements such as types, fields, methods, and properties. Attributes are saved with the metadata of a .NET Framework file and can be used to describe code to the common language runtime or to affect application behavior at run time.
In .NET Framework security, the process of discovering and verifying the identity of a principal by examining the user's credentials against some authority. See also: principal.
In .NET Framework security, the process of limiting access rights by granting or denying specific permissions to an authenticated identity or principal. See also: authentication, principal.
A button that appears on the edge of a frame when a window is in auto-hide mode. The hidden window pane appears when the mouse cursor hovers over the button.
In ASP.NET server controls, a setting that causes the control to submit the page when the user interacts with the control. (By default, only button controls cause a postback.) For example, if a DropDownList control is set to perform autopostback, the page is submitted as soon as a user selects an item from the list. See also: ASP.NET server control.
The size and location of an object.
The conversion of a value type instance to an object, which implies that the instance will carry full type information at run time and will be allocated in the heap. The Microsoft intermediate language (MSIL) instruction set's box instruction converts a value type to an object by making a copy of the value type and embedding it in a newly allocated object. See also: Microsoft intermediate language, unboxing, value type.
The recorded text output of a Visual Studio build, often indicating command lines issued and status of each step in the build process. For a C++ build, this file is called BuildLog.htm.
A programming language designed for building enterprise applications that run on the .NET Framework. C#, which is an evolution of C and C++, is type safe and object oriented. Because it is compiled as managed code, it benefits from the services of the common language runtime, such as language interoperability, security, and garbage collection.
See title bar.
A static pane that can display one or more of the following objects: a button, a text label, and an image.
A button that is displayed on the caption bar of a dockable pane or mini-frame window.
A Web page in WML. WML devices can either display the contents of a card on a single screen or, when necessary, provide scroll bars so that the entire contents of the card can be viewed. Developers do not need to worry about manipulating cards or decks (groups of cards) because ASP.NET mobile controls handle formatting (including pagination) for targeted devices. See also: deck, WML.
A list of Web Parts controls (or other Web server, custom server, or user controls), created by a System.Web.UI.WebControls.CatalogPart control, that users can add to a Web Parts page. See also: Web Parts controls, Web Parts page.
See other term: COM callable wrapper (CCW)
The double angle bracket denoting an overflow button control.
The common user interface elements rendered around each Web Parts part control within a given zone. The chrome for a part control includes a border, a title bar, and the icons, title text, and verbs menu that appear within the title bar. The appearance of the chrome is set at the zone level and applies to all part controls in a zone. The rendering of chrome and of individual System.Web.UI.WebControls.WebParts.WebPart controls is handled by the System.Web.UI.WebControls.WebParts.WebPartChrome class. See also: part controls, Web Parts controls, zone.
A markup language used on some cell phones. cHTML is a subset of HTML with additional tags to enhance mobile functionality.
See other term: Common Information Model (CIM)
CIM Object Manager
A component in the WMI infrastructure that handles the interaction between management applications and providers. The CIM Object Manager supports services such as event notification, remote access, and query processing. The CIM Object Manager also grants access to the WMI repository.
In WMI, a collection of class definitions used to represent managed objects that occur in every management environment. See also: schema.
A reference type that encapsulates data (constants and fields) and behavior (methods, properties, indexers, events, operators, instance constructors, static constructors, and destructors), and can contain nested types. Class types support inheritance, a mechanism whereby a derived class can extend and specialize a base class. See also: encapsulation, indexer, property, reference type.
A visual design environment that enables you to visualize the structure of classes and other types. The Class Designer also enables you to edit the source code of classes and types through these visual representations.
In IIS 7.0, a configuration in which request processing emulates the model used in IIS 6.0. In Classic mode, IIS receives requests and dispatches them to ISAPI components according to mapped file name extensions. IIS and the process that handles the request run as separate processes. For example, requests for ASP.NET resources are dispatched to the aspnet_isapi.dll component.
A deployment method that enables you to publish Windows-based applications to a Web server or network file share for simplified installation.

See other term: common language runtime
See other term: Common Language Specification (CLS)
Code that publicly exposes only language features that are in the Common Language Specification. CLS compliance can apply to classes, interfaces, components, and tools. See also: Common Language Specification (CLS).
code access security
A mechanism provided by the common language runtime whereby managed code is granted permissions by security policy and these permissions are enforced, helping to limit the operations that the code will be allowed to perform.
A class that is accessed by an .aspx file, but resides in a separate file (such as a .dll or .cs file). For example, you can write a code-behind class that creates an ASP.NET custom server control, contains code that is called from an .aspx file, but does not reside within the .aspx file.
A code file containing the page class that implements the program logic of a Web Forms or ASP.NET mobile Web Forms application.
See other term: code-behind file
color menu button
A button that drops down to expose a color palette when a user clicks it.
A control that allows a user to select a color.
COM callable wrapper (CCW)
A proxy object generated by the common language runtime so that existing COM applications can use managed classes, including .NET Framework classes, transparently.
A service that enables .NET Framework objects to communicate with COM objects.
Common Information Model (CIM)
In WMI, the model that describes how to represent real-world managed objects. CIM uses an object-oriented paradigm, where managed objects are modeled using the concepts of classes and instances. The CIM is divided into the metamodel and the standard schema. The metamodel describes what types of entities make up the schema. It also defines how these entities can be combined into objects that represent real-world devices.
common language runtime
The engine at the core of managed code execution. The runtime supplies managed code with services such as cross-language integration, code access security, object lifetime management, and debugging and profiling support.
common language runtime host
An unmanaged application that uses a set of APIs, called the hosting interfaces, to integrate managed code into the application. Common language runtime hosts often require a high degree of customization over the runtime that is loaded into the process. The hosting interfaces allow common language runtime hosts to specify settings that configure the garbage collector, select the appropriate build for their environment (server versus workstation), and so on. Common language runtime hosts often support an extensibility model that allows the end user to dynamically add new pieces of functionality, such as a new control or a user-written function. These extensions are typically isolated from each other in the process using application domains and custom security settings. Examples of common language runtime hosts include ASP.NET, Microsoft Internet Explorer, and a host to run executables launched from the Windows Shell. See also: application domain, common language runtime, managed code.
Common Language Specification (CLS)

See other term: Web Parts connection
A System.Web.UI.WebControls.WebParts.ConnectionPoint object associated with the provider and consumer controls that participate in Web Parts connections. A connection point manages the exchange of data between the controls. Providers and consumers each have their own connection points. See also: consumer, provider, Web Parts connection.
See other term: generic type parameter constraint
constructed generic type
A generic type whose generic type parameters have been specified. A constructed type or method can be an open generic type if some of its type arguments are type parameters of enclosing types or methods, or a closed generic type if all of its type arguments are real types. See also: closed generic type, generics, generic type, generic type argument, generic type parameter, open generic type.
See other term: constructed generic type
In a Web Parts connection, a server control that receives data from a provider control and processes or displays it. A consumer can be any type of server control, but must be designed to function as a consumer. A consumer must have a special callback method marked with a ConnectionConsumerAttribute attribute in the source code. This method receives data from the provider in the form of an interface instance. See also: connection point, provider, Web Parts connection.
See other term: naming container
A type of ASP.NET mobile control that contains other controls and provides visual groupings of controls and content.
A control that defines an area of a Microsoft Office Word document in which text and specific types of data can be displayed, or in which user input is restricted.
In ASP.NET, a Web page that is configured to be merged with a master page to create a complete page. See also: master page.
An ordered sequence of properties that define an environment for the objects that resides inside it. Contexts are created during the activation process for objects that are configured to require certain automatic services such as synchronization, transactions, just-in-time activation, security, and so on. Multiple objects can live inside a context.
The implicit state, and code to manage that state, held on behalf of an object instance. For example, the transaction context property holds the transaction identifier of the transaction that the object is participating in.
The behavior and state that a class provides, which is matched with what a client of that class can expect to hold. A contract is expressed partly by the signatures for all public fields, methods, properties, and events of that class. This is augmented by a description (usually in simple descriptive text) of what each field or property represents, together with what each method does. In the .NET Framework add-in programming model, a non-versioning interface that defines the methods and specifies the data types for transferring data over the communication pipeline between the host and the add-in. The contract is in the middle of the communication pipeline between the add-in and the host. The contract assembly is loaded into the application domains of both the add-in and the host. See also: add-in, host, pipeline.
A field in an ASP.NET Web page that stores the current property settings for server controls on the page. Control state is used to recreate the page and reestablish previous settings on each postback. See also: ASP.NET page, ASP.NET server control, postback, view state.
In ASP.NET Web pages, the process of submitting a page to a specified target page in contrast to submitting the page to itself. See also: postback.
See other term: conceptual schema definition language
See other term: common type system

custom build rule
A build rule defined by the user, typically to call a tool that is not part of the normal Visual Studio build process.
A control authored by a user or a third-party software vendor that does not belong to the .NET Framework class library. This is a generic term that also includes user controls. Custom server controls are used in Web Forms (ASP.NET pages). Custom client controls are used in Windows Forms applications.
The process or method for configuring controls on a form or Web page to fetch data from or write data to a data source such as a database, XML file, and so on.
data source control
An object that can be added to an ASP.NET Web page that encapsulates the logic required to connect to a data source, such as a database or XML file, and that can execute queries or other data-access commands. A data source control can in turn provide data to other controls on that page.
A set of visual tools for creating and editing typed datasets and the individual items that make up datasets.
A set of XML files on your desktop computer that contains information about the platforms, devices, emulators, and packages that are installed on the computer.

The contents of the Datastore are modified whenever you install an SDK that is based on Windows CE such as Windows Mobile.
In multithreading, a condition in which each of two threads holds a lock that the other thread needs in order to proceed. See also: synchronization.
A group of one or more cards. See also: card.
declarative security check
Declarative security information in metadata. Developers can use such declarations, which are usually written as custom attributes, to invoke several kinds of security functionality: require permissions to bind reference to the code, require permissions to derive a type, demand that callers have certain permissions, and so on. See also: imperative security check.
A provider hosted in a separate process from WMI. Decoupled providers are the recommended way to instrument an application because the provider can control its own lifetime instead of being launched every time a user accesses the provider through WMI. See also: provider.
default unit system
The process that determines when a Web page control should appear on a new page, based on a mobile device's characteristics. The default unit system is based on one line equaling 100 units, as indicated by the DefaultWeight field in the ControlPager class.
The characteristic of a LINQ query that it is not executed until it is iterated through a call to its IEnumerator.MoveNext method. The method call may occur directly, indirectly through a foreach (C#) or For Each (Visual Basic) statement, or through a call to a Standard Query Operator method such as Max, Average, Count, ToArray, or ToList.
In the .NET Framework, a reference to a function. A delegate is equivalent to a function pointer. See also: reference type.
In WMI, a security impersonation level used to allow remote access involving more than one network hop.
A filter that uses a custom method to evaluate the specified data.
By denying a permission, a method can prevent its callers from exercising the privilege represented by that permission. If a method on the call stack denies permission A, a stack walk checking for permission A will fail unless a valid assertion is found on the stack between the method doing the denial and the method that initiated the check for permission A. See also: assertion.
denial of service attack
An attack on a server exposed to the Internet that consumes excessive time, memory, or other resources. The attack intends to prevent rightful access to resources.

The different display states that a Web Parts page can enter, which enable users to modify a page in specified ways. The states that ship with the Web Parts control set are: catalog, connect, design, edit, and browse. The default or normal mode for a Web page is browse. Developers can extend this display mode feature by adding custom display modes, which requires extending the WebPartManager class. See also: Web Parts control set, Web Parts page.
The way of determining which control borders are set flush with their parent control and how a control is resized with its parent. Docking and anchoring are mutually exclusive. See also: anchoring.
A portion of the color bar that allows the user to select one color from the set of colors in the current document.
A supplemental program that modifies or adds functionality to an existing program or application, but only when a specific document is open.
See other term: assembly cache
A Web Parts control that is persisted in a personalization store; it does not appear in the declarative markup of an .aspx page. After it has been added to a page, the WebPartManager control automatically creates an instance of the control from the personalization store on future requests. See also: Web Parts controls.
In ASP.NET, a framework that facilitates the creation of data-driven Web applications. Dynamic Data uses customizable page and field templates, scaffolding, user-definable metadata, and convention-based naming to create UI that displays data, lets users navigate relationships between tables, and lets users edit and create data (CRUD operations).

A Web Parts control that is part of the declarative "page persistence" markup in an .aspx page; it exists only as part of the .aspx page, not in a personalization store like a dynamic Web Parts control. Unlike a dynamic control, a static control is added to an .aspx page on every request. A static Web Parts control is always a shared control, which means that although users can both personalize and "close" the control when the page is in either shared or user scope, the control can never be permanently deleted. See also: personalization, personalization scope, shared control, Web Parts control.

A name that consists of an assembly's identity-its simple text name, version number, and culture information (if provided)-strengthened by a public key and a digital signature generated over the assembly. Because the assembly manifest contains file hashes for all the files that constitute the assembly implementation, it is sufficient to generate the digital signature over just the one file in the assembly that contains the assembly manifest. Assemblies with the same strong name are expected to be identical. See also: assembly, assembly manifest.
A user-defined value type. Like a class, structures can contain constructors, constants, fields, methods, properties, indexers, operators, and nested types. Unlike classes, however, structures do not support inheritance. See also: class, field, indexer, nested type, property, value type.

In ASP.NET: An ASP.NET server control that does not itself provide a visual interface but allows its users (page developers) to supply templates that provide a visual interface. When the ASP.NET page parser encounters a templated control, it parses the control's template and dynamically creates child controls that supply the visual interface. The Repeater and DataList ASP.NET server controls are templated controls. The DataGrid control is not strictly a templated control, but uses templates to customize its user interface. See also: ASP.NET server control, template.
In ASP.NET mobile controls: A control that supports one or more templates. A single templated control can refer to multiple sets of templates, where each template set is defined through device-specific criteria. See also: template, template set.

Uniform Resource Identifier (URI)
A number or name that uniquely identifies an element or attribute. URIs include both Uniform Resource Names (URNs) and Uniform Resource Locators (URLs). URIs are a general scheme for locating resources on the Internet that focuses more on the resource and less on the location. In theory, a URI could find the closest copy of a mirrored document or locate a document moved from one site to another. Although it is expected that URNs will become more common in the future, when discussing XML today, URIs are URLs in nearly all cases.
Universal Description, Discovery, and Integration (UDDI)
A platform-independent framework functioning like a directory (similar to a telephone book) that provides a way to locate and register Web services on the Internet. The UDDI specification calls for three elements: white pages, which provide business contact information; yellow pages, which organize Web services into categories (for example, credit card authorization services); and green pages, which provide detailed technical information about individual services. The UDDI also contains an operational registry, which is available today.

In ASP.NET: A server control that is authored declaratively using the same syntax as an ASP.NET page and is saved as a text file with an .ascx extension. User controls allow page functionality to be partitioned and reused. Upon first request, the page framework parses a user control into a class that derives from System.Web.UI.UserControl and compiles that class into an assembly, which it reuses on subsequent requests. User controls are easy to develop due to their page-style authoring and deployment without prior compilation.
In Windows Forms: A composite control that provides consistent behavior and user interface within or across applications. The user control can be local to one application or added to a library and compiled into a DLL for use by multiple applications.
user-defined type (UDT)
A base data type that is explicitly defined with a new name by using the pre-compiler's typedef directive. It is equivalent to the base type from which it was defined.
validation server controls
A set of server controls, included with ASP.NET, that verify user input. The input is checked as it comes from HTML server controls and Web server controls (for example, a Web page form) against programmer-defined requirements. Validation controls perform input checking in server code. If the user is working with a browser that supports DHTML, the validation controls can also perform validation using client script. See also ASP.NET server control, HTML server control, Web server control.
See other term: validation server controls
A data type that is represented by the type's actual value. If a value type is assigned to a variable, that variable is given a fresh copy of the value. (This is in contrast to a reference type, where assignment does not create a copy.) Value types are usually created on a method's stack frame, rather than in the garbage-collected heap. A value type can be boxed, which is a process that creates a corresponding reference type. See also: boxing, reference type, unboxing.
A user interface element in a Web Parts application that an end user can click to perform actions such as closing, minimizing, restoring, editing, or deleting a Web Parts control. Developers can also add custom verbs to controls. Web Parts verbs are based on the System.Web.UI.WebControls.WebParts.WebPartVerb class. See Web Parts controls.
A menu in the title bar of a part control that contains various verbs (UI actions that apply to an individual control) such as Close, Minimize, Restore, Delete, Export, Edit, Help, and others, as well as custom verbs implemented by developers. See part control, verb.
A part of the compilation process in which code is checked for conformance to a specific set of rules defined to allow proof of certain security requirements. The common language runtime can verify Microsoft intermediate language (MSIL). See also: Microsoft intermediate language (MSIL).

A field in an ASP.NET Web page where you can store settings that need to be preserved between postbacks. Also used to mean control state. See also: control state, postback.
The portion of a DataRepeater control on which repeated items will be displayed at run time.
virtual address (VA)
For systems with virtual memory, a memory location that intervening hardware and/or software maps to physical memory. As an application runs, the same virtual address can be mapped to many different physical addresses as data and programs are paged out and paged in to new memory locations.
virtual-mode data binding
A type of data binding in which a data-bound control retrieves only as many rows from the database as the user will be able to see on the screen.
A class that provides support for changing the appearance of an application at a global level. The CMFCVisualManager class works together with a class that is named a visual manager. Each visual manager provides instructions to draw the GUI controls of an application by using a consistent GUI style, for example, the Office 2003 style.
