Web-based Enterprise Management (WBEM)

An initiative undertaken by the Distributed Management Task Force (DMTF) to provide enterprise system managers with a standard solution for management. WMI is the Microsoft implementation of the WBEM initiative for Windows operating systems.

Web Forms

The ASP.NET page framework, which consists of programmable Web pages (called Web Forms pages) that contain reusable server controls. See also ASP.NET server control.

Web Parts

The total ASP.NET Web Parts feature set.

Web Parts connection

An association between two server controls residing in a WebPartZoneBase zone that enables them to share data, with one control acting as the provider of data and the other control acting as the consumer. A connection is encapsulated within a System.Web.UI.WebControls.WebParts.WebPartConnection object. See also: consumer, provider, zone.

Web Parts controls

A way of referring generally to any of the various types of controls in the Web Parts control set. See also: Web Parts control set.

Web Parts control set

The integrated set of ASP.NET software components that provide personalization, structural components such as zones and the WebPartManager control, Web Parts UI controls, and other components for building Web Parts controls and applications. See also: personalization, Web Parts controls, zone.

Web Parts page

A normal .aspx page that includes the Web Parts controls that are necessary to personalize the page. A Web Parts page minimally requires a WebPartManager control, one or more zones, and one or more Web Parts controls. See also: personalization, Web Parts controls, zone.

Web server control

An ASP.NET server control that belongs to the System.Web.UI.WebControls namespace. Web server controls are richer and more abstract than HTML server controls. A Web server control has an asp tag prefix on an ASP.NET page, such as <asp:Button runat="server" />. See also: ASP.NET server control, HTML server control, validation server controls.

Web Services Description Language (WSDL)

An XML-based contract language for describing network services offered by a server. See also: Extensible Markup Language (XML).


A clause in the WQL SELECT statement that constrains a query so that subsets of class definitions or class instances can be selected. WHERE clauses can also be used to limit the scope of event notifications. See also: ASSOCIATORS OF, GROUP, HAVING, ISA, REFERENCES OF, SELECT, WITHIN.

Windows Forms

A rich Windows client library.

Windows Management Instrumentation (WMI)

WMI is the Microsoft extension to the Distributed Management Task Force (DMTF) Web-based Enterprise Management (WBEM) initiative, and provides a set of interfaces for access to components that provide management capabilities to an enterprise. See also: Web-based Enterprise Management.


A clause in the WQL SELECT statement that constrains the granularity of event delivery time, and supports polling for events when no event provider is available. See also: ASSOCIATORS OF, GROUP, HAVING, ISA, REFERENCES OF, SELECT, WHERE.


See Windows Management Instrumentation.

WMI class

A template for a type of managed object. WMI classes define the basic units of management. For example, the Win32_LogicalDisk class is a template for all logical disks that occur in the Windows environment. In this case, WMI uses the class template to generate an instance of Win32_LogicalDisk for each disk installed on a computer.


An XML-based markup language used to specify content and the user interface for narrowband devices, including cellular phones and pagers. WML is part of WAP. See also: WAP.

world coordinates

The coordinates used to model a particular graphic world.

world transformation

The transformation that converts world coordinates to page coordinates. See also: page coordinates, world coordinates.
