Overview of the Windows Management Instrumentation technology.

To develop Windows Management Instrumentation, you need these headers:

• chptrarr.h
• chstrarr.h
• chstring.h
• frquery.h
• instance.h
• methodco.h
• objpath.h
• refptrco.h
• thrdbase.h

Class

CFrameworkQuery The CFrameworkQuery class is used to parse and manipulate a query. It contains methods that return specific property values and methods that test the query to determine the particular properties that are included.
CHPtrArray The CHPtrArray class is part of the WMI Provider Framework. CHPtrArray is a utility interface for array pointer management used for provider handling of WMI queries.
CHString The following table lists the CHString methods.
CHStringArray The following table lists the CHStringArray methods and operators.
CInstance The CInstance class is used to retrieve and update the values of properties defined for the instances supported by the WMI Provider Framework. The CInstance class also provides access to the provider framework's implementation of the CInstance interface.
CObjectPathParser Parses a WMI path which can include a remote computer name, namespaces, and classes. Use of this object is not recommended. Instead, use the IWbemPath COM interface.
CThreadBase The CThreadBase class is a base class that supplies the internal thread safety mechanisms for the WMI Provider Framework. This class is called internally.
CWbemGlueFactory The CWbemGlueFactory class is part of the WMI Provider Framework. The Provider Framework implements methods of this interface internally to create new instances of classes for the provider.
CWbemProviderGlue CWbemProviderGlue ties the Component Object Model (COM) interfaces of the Windows Management Instrumentation (WMI) API to the classes derived from the Provider class, and supplies methods for providers to use to query each other.
MethodContext The MethodContext class is the pointer to a structure used in a provider to get or set IWbemClassObject information. WMI does not implement any functionality based on the pointer.
Provider The Provider class is the base class for the class or classes that the framework provider supports.
TRefPointerCollection The TRefPointerCollection class is a container class that collects pointers to objects. These pointers can be enumerated.
WBEMTime The WBEMTime class facilitates conversions between various Windows and ANSI C run-time time formats. For more information, see also WBEMTimeSpan Class Methods.
