3.1.4.1.4 get_EventObjectChangeEventClassID (Opnum 10)

  • 發行項

The get_EventObjectChangeEventClassID method extracts the server-specific EventClassID for server-specific event class or subscription change notifications.

 [id(4), propget, helpstring("method get_EventObjectChangeEventClassID")] HRESULT EventObjectChangeEventClassID(
   [out, retval] BSTR* pbstrEventClassID
 );

pbstrEventClassID: If the method call returns a success HRESULT, this MUST contain the returned unique identifier representing the EventClassID for the server specific EventClass/Subscription change notifications. This MUST be a GUID specified as a string as specified in section 2.2.3.

Return Values: An HRESULT specifying success or failure. All success codes MUST be treated the same, and all failure codes MUST be treated the same.

When this method is called, a server SHOULD return the EventClassID of an event class supporting notifications of changes to the server’s event class store and subscriber store. The server MAY instead fail the method call if it does not support such an event class.
