WshNetwork Object


Provides access to the shared resources
on the network to which your computer is
connected.
You create a WshNetwork object when
you want to connect to network shares
and network printers, disconnect from
network shares and network printers,
map or remove network shares, or access
information about a user on the network.

WshNetwork Object

The following example demonstrates
displaying the domain name, computer
name, and user name for the current
computer system using the WshNetwork
object.
Set objWshNetwork = CreateObject("WScript.Network")
MsgBox "Domain = " & objWshNetwork.UserDomain
MsgBox "Computer Name = " & objWshNetwork.ComputerName
MsgBox "User Name = " & objWshNetwork.UserName

AddWindowsPrinterConnection Method


Adds a Windows-based printer connection to your
computer system.
Syntax




object.AddWindowsPrinterConnection( strPrinterPath )
Using this method is similar to using the Printer
option on Control Panel to add a printer
connection.
Unlike the AddPrinterConnection method, this
method allows you to create a printer connection
without directing it to a specific port, such as
LPT1.
If the connection fails, an error is thrown.

WshNetwork Object
MapNetworkDrive Method


Adds a shared network drive to your
computer system.
Syntax


object.MapNetworkDrive(strLocalNa
me, strRemoteName, [bUpdateProfile],
[strUser], [strPassword])
An attempt to map a non-shared
network drive results in an error.
7
WshShell Object



You create a WshShell object whenever
you want to run a program locally,
manipulate the contents of the registry,
create a shortcut, or access a system
folder.
The WshShell object provides the
Environment collection.
This collection allows you to handle
environmental variables (such as
WINDIR, PATH, or PROMPT).
8
WshShell Object
CreateShortcut Method


Creates a new shortcut, or opens an existing shortcut.
Syntax




object.CreateShortcut(strPathname)
The CreateShortcut method returns either a
WshShortcut object or a WshURLShortcut object.
Simply calling the CreateShortcut method does not
result in the creation of a shortcut.
The shortcut object and changes you may have made
to it are stored in memory until you save it to disk with
the Save method.

WshShell Object
Special Folders Property


Returns a SpecialFolders object (a collection of
special folders).
Syntax




object.SpecialFolders(objWshSpecialFolders)
The WshSpecialFolders object is a collection.
It contains the entire set of Windows special folders,
such as the Desktop folder, the Start Menu folder, and
the Personal Documents folder.
The special folder name is used to index into the
collection to retrieve the special folder you want.
The SpecialFolders property returns an empty string
if the requested folder (strFolderName) is not available.

WMI
Windows Management Instrumentation




Windows® Management Instrumentation (WMI) is a
component of the Microsoft® Windows® operating system
and is the Microsoft implementation of Web-Based Enterprise
Management (WBEM), which is an industry initiative to
develop a standard technology for accessing management
information in an enterprise environment.
WMI uses the Common Information Model (CIM) industry
standard to represent systems, applications, networks,
devices, and other managed components.
You can use WMI to automate administrative tasks in an
enterprise environment.
WMI can be used in all Windows-based applications, and is
most useful in enterprise applications.

The Win32_OperatingSystem WMI
class represents an operating system
installed on a Windows computer system.
