dwSize: The size, in bytes, of the structure.

dwType: A value from the NtmsObjectsTypes (section 2.2.1.6) enumeration specifying the type of the object.

Created: A SYSTEMTIME structure specifying the time when the object was created.

Modified: A SYSTEMTIME structure specifying the time when the object was last modified.

ObjectGuid: The identifier of the object.

Enabled: If set to TRUE, the object MUST be enabled; if set to FALSE, the object MUST NOT be enabled.

dwOperationalState: A value from the NtmsOperationalState (section 2.2.4.5) enumeration specifying the operation state of the object.

szName: A null-terminated sequence of Unicode UTF-16 characters specifying the name of the object.

szDescription: The null-terminated description of the object.<14>

Info: A device or system control object information that is specific to the value of dwType.
