備註

Business logic handlers are registered by calling RegisterBusinessLogicHandler. The properties of the BusinessLogicHandler object must be set before calling RegisterBusinessLogicHandler.

Business logic handler registrations are removed by calling UnregisterBusinessLogicHandler.

Call EnumBusinessLogicHandlers to get a list of business logic handlers that are registered on a server.
