Windows Management Instrumentation

Overview of the Windows Management Instrumentation technology.

To develop Windows Management Instrumentation, you need these headers:

For programming guidance for this technology, see:

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.

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

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.
