Comentários

Manipuladores lógicos de negócios são registrados chamando RegisterBusinessLogicHandler. As propriedades do BusinessLogicHandler objeto devem ser definidas antes de chamar RegisterBusinessLogicHandler.

Os registros do manipulador lógico de negócios são removidos chamando UnregisterBusinessLogicHandler.

Chame EnumBusinessLogicHandlers para obter uma lista de manipuladores de lógica de negócios registrados em um servidor.
