CWbemProviderGlue class (wbemglue.h)

[The CWbemProviderGlue class is part of the WMI Provider Framework which is now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.]

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. It is not expected that provider writers ever derive from this class, or create instances of this class. Typically, the provider writer uses the static methods listed here to retrieve information from WMI. The CWbemProviderGlue is a COM interface, and it relies on COM security for interprocess communication. For more information, see Setting the Security Levels on a WMI Connection and Setting the Security on IWbemServices and Other Proxies.

CWbemProviderGlue has these types of members:

Method	Description
FrameworkLoginDLL	Called when the DLL_PROCESS_ATTACH value is sent to DllMain to determine whether the provider server can be loaded.
FrameworkLogoffDLL	Called by DllCanUnloadNow to determine whether the provider server is not in use and can be unloaded.
GetAllDerivedInstances	Retrieves a list of instances derived from a particular base class.
GetAllDerivedInstancesAsynch	Retrieves a list of instances supported by a particular provider and derived from a particular base class. Returns one instance at a time.
GetAllInstances	Retrieves a list of instances supported by a particular provider.
GetAllInstancesAsynch	Retrieves a list of instances supported by a particular provider. Returns one instance at a time.
GetEmptyInstance	Overloaded. Retrieves a single instance from a particular provider.
GetInstanceByPath	Retrieves the instance identified by a particular object path.
GetInstanceKeysByPath	Retrieves the instance identified by a particular object path, with only the key properties populated.
GetInstancePropertiesByPath	Retrieves the instance identified by a particular object path, with only the specified properties populated.
GetInstancesByQuery	Retrieves a list of instances that match a particular query.
GetInstancesByQueryAsynch	Retrieves a list of instances supported by a particular provider that match a particular query. Returns one instance at a time.
GetNamespaceConnection	Retrieves a namespace connection.
IsDerivedFrom	Determines whether one class is derived from another.
SetStatusObject	Sets the parameters of a status object which is used to supply more information when an error occurs.

Inheritance

The CWbemProviderGlue class implements IWbemServicesIWbemProviderInit.

Methods

The CWbemProviderGlue class has these methods.

CWbemProviderGlue::FrameworkLoginDLL The FrameworkLoginDLL method is called when the DLL_PROCESS_ATTACH value is sent to DllMain to determine whether the provider server can be loaded. (overload 1/2)
CWbemProviderGlue::FrameworkLoginDLL The FrameworkLoginDLL method is called when the DLL_PROCESS_ATTACH value is sent to DllMain to determine whether the provider server can be loaded. (overload 2/2)
CWbemProviderGlue::FrameworkLogoffDLL The FrameworkLogoffDLL method is called by DllCanUnloadNow to determine whether the provider server is not in use and can be unloaded. (overload 1/2)
CWbemProviderGlue::FrameworkLogoffDLL The FrameworkLogoffDLL method is called by DllCanUnloadNow to determine whether the provider server is not in use and can be unloaded. (overload 2/2)
CWbemProviderGlue::GetAllDerivedInstances The GetAllDerivedInstances method retrieves a list of instances of a base class, or any children of that base class.
CWbemProviderGlue::GetAllDerivedInstancesAsynch The GetAllDerivedInstancesAsynch method retrieves a list of instances supported by a particular provider and derived from a particular base class. This method allows the provider to respond asynchronously by returning one instance at a time.
CWbemProviderGlue::GetAllInstances The GetAllInstances method retrieves a list of instances returned by a specific class.
CWbemProviderGlue::GetAllInstancesAsynch The GetAllInstancesAsynch method retrieves a list of instances returned by a specific class. This method allows the provider to respond asynchronously by returning one instance at a time.
CWbemProviderGlue::GetEmptyInstance The GetEmptyInstance method retrieves a single unpopulated instance of the specified class. (overload 1/2)
CWbemProviderGlue::GetEmptyInstance The GetEmptyInstance method retrieves a single unpopulated instance of the specified class. (overload 2/2)
CWbemProviderGlue::GetInstanceByPath The CWbemProviderGlue::GetInstanceByPath (wbemglue.h) method retrieves the instance identified by a particular object path.
CWbemProviderGlue::GetInstanceByPath The CWbemProviderGlue::GetInstanceByPath (wbemglue.h) method retrieves the instance identified by a particular object path by calling the provider GetObject method.
CWbemProviderGlue::GetInstanceKeysByPath The GetInstanceKeysByPath method retrieves the instance identified by a particular object path, with only the key properties populated.
CWbemProviderGlue::GetInstancePropertiesByPath Retrieves the instance identified by a particular object path, with only the specified properties populated. The properties to be populated are named in a CHString array.
CWbemProviderGlue::GetInstancesByQuery The CWbemProviderGlue::GetInstancesByQuery (wbemglue.h) method retrieves a list of instances that match a particular query.
CWbemProviderGlue::GetInstancesByQuery The CWbemProviderGlue::GetInstancesByQuery (wbemglue.h) method retrieves a list of instances that match a particular query.
CWbemProviderGlue::GetInstancesByQueryAsynch The GetInstancesByQueryAsynch method retrieves a list of instances supported by a particular provider, and that match a particular query. This method allows the provider to respond asynchronously by returning one instance at a time.
CWbemProviderGlue::GetNamespaceConnection The GetNameSpaceConnection method is used to retrieve a namespace connection. (overload 2/2)
CWbemProviderGlue::GetNamespaceConnection The GetNameSpaceConnection method is used to retrieve a namespace connection. (overload 1/2)
CWbemProviderGlue::IsDerivedFrom The CWbemProviderGlue::IsDerivedFrom(wbemglue.h) method determines whether one class is derived from another.
CWbemProviderGlue::IsDerivedFrom The CWbemProviderGlue::IsDerivedFrom (wbemglue.h) method determines whether one class is derived from another.
CWbemProviderGlue::SetStatusObject The SetStatusObject method sets the parameters of a status object used to supply more information when an error occurs. This status object is derived from the Win32_PrivilegesStatus class.
