Comentarios

Los controladores de lógica de negocios se registran mediante una llamada a RegisterBusinessLogicHandler. Las propiedades del BusinessLogicHandler objeto deben establecerse antes de llamar a RegisterBusinessLogicHandler.

Los registros del controlador de lógica de negocios se quitan mediante una llamada a UnregisterBusinessLogicHandler.

Llame EnumBusinessLogicHandlers a para obtener una lista de controladores de lógica de negocios registrados en un servidor.

Constructores
