Calling Convention

These methods can be called only from a WMI instance object.

Description

Stores changes performed to one or more properties.

It is not possible to get an instance of OV_ExternalNode to reflect changes to its properties from within IWbemService::ExecMethodAsync. For this reason, the method specifies an instance of OV_ExternalNode as the Node parameter, even though this method is already called in the context of this instance.

As with the OV_ExternalNode::Create method, the method performs the following checking:

• If a required property is missing, the method fails with MDLAPI_E_PROPERTY_MISSING.
• If the Caption property is an empty string, contains invalid characters, or has more then 1024 characters, the method fails with MDLAPI_E_INVALID_CAPTION.
• If a property has an invalid value, the method fails with MDLAPI_E_INVALID_PROPERTY.
• If an external node with the same hierarchical path already exists, the method fails with MDLAPI_E_EXT_NODE_HIERPATH_EXISTS.

Return Value

None.
