[HostProtectionAttribute(SecurityAction.LinkDemand, Resources = HostProtectionResource.ExternalProcessMgmt)]
public class Computer : ServerComputer

The Computer type exposes the following members.

Public methodComputerInitializes a new instance of the Computer class.

Public propertyAudioGets an object that provides properties for methods for playing sounds.
Public propertyClipboardGets an object that provides methods for manipulating the Clipboard.
Public propertyClockGets an object that provides properties for accessing the current local time and Universal Coordinated Time (the equivalent to Greenwich Mean Time) from the system clock. (Inherited from ServerComputer.)
Public propertyFileSystemGets an object that provides properties and methods for working with drives, files, and directories. (Inherited from ServerComputer.)
Public propertyInfoGets an object that provides properties for getting information about the computer's memory, loaded assemblies, name, and operating system. (Inherited from ServerComputer.)
Public propertyKeyboardGets an object that provides properties for accessing the current state of the keyboard, such as what keys are currently pressed, and provides a method to send keystrokes to the active window.
Public propertyMouseGets an object that provides properties for getting information about the format and configuration of the mouse installed on the local computer.
Public propertyNameGets the computer name. (Inherited from ServerComputer.)
Public propertyNetworkGets an object that provides a property and methods for interacting with the network to which the computer is connected. (Inherited from ServerComputer.)
Public propertyPortsGets an object that provides a property and a method for accessing the computer's serial ports.
Public propertyRegistryGets an object that provides properties and methods for manipulating the registry. (Inherited from ServerComputer.)
Public propertyScreenGets the Screen object that represents the computer's primary display screen.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The properties exposed by the My.Computer object return information about the computer on which the application is deployed, as determined at run time. Typically, this data differs from what was available on the development computer.

Some members, such as the My.Computer.Audio object, are available only for non-server applications.

The following table lists examples of tasks involving the My.Computer object.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Resources. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This example uses the My.Computer.Name property to display the name of the computer on which the code runs.

MsgBox("Computer name: " & My.Computer.Name)
