5.4 WMI and some Windows applications

5.4.1 Microsoft Office

Both Office 2000 and Office XP come with their WMI instance providers. Office 2000 registers a provider called OffProv in the Root\MSAPPS namespace, while Office XP registers a provider called OffProv10 in the Root\MSAPPS10 namespace (see Table 5.29).

Table 5.29: The Office Provider Capabilities
Provider Name	Provider Namespace	Instance Provider	Support Get	Support Enumeration
Office 2000 and XP Providers
OffProv (Office 2000)	Root/MSAPPS	X	X	X
OffProv10 (Office XP)	Root/MSAPPS10	X	X	X

Both providers support a set of classes representing management information about Office. Office XP comes with some additional classes compared with Office 2000. Table 5.30 shows the classes available under Office 2000 and Office XP.

As shown in Table 5.29, the information about Office instances can't be updated. For instance, if you need to determine if a Word document is open, you can request the instances of the Win32_WordDocument class. The output would be as follows:

 1:    C:\>GetCollectionOfInstances.wsf Win32_WordDocument /Namespace:Root\MSAPPS 2:    Microsoft (R) Windows Script Host Version 5.6 3:    Copyright (C) Microsoft Corporation 1996–2001. All rights reserved. 4: 5: 6:    CreateDate: .............................. 20010118112800.******+*** 7:    *Name: ...................................

5.4.2 Internet Explorer

Internet Explorer 5.0 (and later) provides a WMI instance provider called IEINFO5. This provider supports a collection of classes representing the configuration settings of Internet Explorer. These classes are available in the Root\CIMV2\Applications\MicrosoftIE namespace (see Table 5.31).

Table 5.31: The Internet Explorer Provider Capabilities
Provider Name	Provider Namespace	Class Provider	Instance Provider	Method Provider	Property Provider	Event Provider	Event Consumer Provider	Support Get	Support Put	Support Enumeration	Support Delete	Windows Server 2003	Windows XP	Windows 2000 Server	Windows 2000 Professional	Windows NT 4.0
Internet Explorer Provider
ieinfo5	Root/CIMv2/Applications/MicrosoftIE		X					X		X		X	X	X	X

As with the Office provider, the Internet Explorer provider doesn't support update of the configuration settings. Therefore, it is a read-only mode provider (see Table 5.32).

Table 5.32: The Internet Explorer WMI Classes
Name	Description
MicrosoftIE_Summary	Retrieves the various settings of Internet Explorer, such as the active printer, the build number, Java Virtual Machine version Service Pack levels and fixes, version, etc.
MicrosoftIE_ConnectionSettings	Retrieves the Dial-up connection settings of Internet Explorer.
MicrosoftIE_Object	Retrieves information about the various ActiveX, Codecs, Objects added to Internet Explorer.
MicrosoftIE_Publisher	Retrieves Internet Explorer publisher information.
MicrosoftIE_LanSettings	Retrieves the LAN connection settings of Internet Explorer.
MicrosoftIE_FileVersion	Retrieves Internet Explorer files information (date, version, etc.).
MicrosoftIE_Certificate	Retrieves Internet Explorer certificates information.
MicrosoftIE_ConnectionSummary	Retrieves Internet Explorer connection summary.
MicrosoftIE_Cache	Retrieves Internet Explorer cache settings.
MicrosoftIE_Security	Retrieves Internet Explorer security settings.

The MicrosoftIE_LanSettings class exposes the same information as the Win32_Proxy class. However, with the SetProxySetting method exposed by the Win32_Proxy class, it is possible to update the Proxy LAN settings. You can refer to Chapter 3 (Sample 3.13, "Managing the Windows Proxy LAN settings") for more information about the Win32_Proxy class.

For instance, if you need to know the certificates available from Internet Explorer, you can request the instances of the MicrosoftIE_Certificate class. The output would be as follows:

  1:    C:\>GetCollectionOfInstances.wsf MicrosoftIE_Certificate                                         /Namespace:Root\CIMv2\Applications\MicrosoftIE  2:    Microsoft (R) Windows Script Host Version 5.6  3:    Copyright (C) Microsoft Corporation 1996–2001.

As another example, if you need to determine the file version used by Internet Explorer, you can request the instances of the MicrosoftIE_FileVersion class. The output would be as follows:

  1:    C:\>GetCollectionOfInstances.wsf MicrosoftIE_FileVersion                                         /Namespace:Root\CIMv2\Applications\MicrosoftIE  2:    Microsoft (R) Windows Script Host Version 5.6  3:    Copyright (C) Microsoft Corporation 1996–2001.
