The Windows Script Host object model consists of 14 objects. The root object is the WScript object.

Object Model Illustration

The illustration that follows represents the Windows Script Host Object Model hierarchy.

The Windows Script Host Object Model Hierarchy

The Windows Script Host object model provides a logical, systematic way to perform many administrative tasks. The set of COM interfaces it provides can be placed into two main categories:

  • Script Execution and Troubleshooting

    This set of interfaces allows scripts to perform basic manipulation of the Windows Script Host, output messages to the screen, and perform basic COM functions such as CreateObject and GetObject.

  • Helper Functions

    Helper functions are properties and methods for performing actions, such as mapping network drives, connecting to printers, retrieving and modifying environment variables, and manipulating registry keys. Administrators can also use the Windows Script Host helper functions to create simple logon scripts.

WSH Objects and Associated Tasks

The following table is a list of the WSH objects and the typical tasks associated with them.

Object What you can do with this object

Wscript

  • Set and retrieve command line arguments

  • Determine the name of the script file

  • Determine the host file name (wscript.exe or cscript.exe)

  • Determine the host version information

  • Create, connect to, and disconnect from COM objects

  • Sink events

  • Stop a script's execution programmatically

  • Output information to the default output device (for example, a dialog box or the command line)

WshArguments

Access the entire set of command-line arguments

WshNamed

Access the set of named command-line arguments

WshUnnamed

Access the set of unnamed command-line arguments

WshNetwork

  • Connect to and disconnect from network shares and network printers

  • Map and unmap network shares

  • Access information about the currently logged-on user

WshController

Create a remote script process using the Controller method CreateScript()

WshRemote

  • Remotely administer computer systems on a computer network

  • Programmatically manipulate other programs/scripts

WshRemote Error

Access the error information available when a remote script (a WshRemote object) terminates as a result of a script error

WshShell

  • Run a program locally

  • Manipulate the contents of the registry

  • Create a shortcut

  • Access a system folder

  • Manipulate environment variables (such as WINDIR, PATH, or PROMPT)

WshShortcut

Programmatically create a shortcut

WshSpecialfolders

Access any of the Windows Special Folders

WshURLShortcut

Programmatically create a shortcut to an Internet resource

WshEnvironment

Access any of the environment variables (such as WINDIR, PATH, or PROMPT)

WshScriptExec

Determine status and error information about a script run with Exec()

Access the StdIn, StdOut, and StdErr channels

In addition to the object interfaces provided by Windows Script Host, administrators can use any ActiveX control that exposes automation interfaces to perform various tasks on the Windows platform. For example, administrators can write scripts to manage the Windows Active Directory Service Interface (ADSI).
