Parámetros

nsApplication
A NSApplication object representing the Notification Services application to which this event provider delivers events.

providerName
A String containing the name of the event provider, as specified in the application definition

args
A StringDictionary containing the names and values of the initialization arguments. This arguments are from the hosted event provider information in the application definition.

stopDelegate
A StopHandler delegate that the event provider can use to call back to the provider host to request termination.

Note that the event provider is not initialized until the Initialize method completes. Calling stopDelegate during initialization has no effect.

Notas

The provider host calls this method to notify the continuous event provider that it must perform initialization. The args parameter provides the initialization arguments for the event provider. For more information about event provider arguments, see Definir proveedores de eventos alojados.

The Initialize method has a five-minute time-out window. If initialization has not completed within that time, an event is logged and the event provider's Terminate method is called.

You use the values provided in the args parameter to set class variables and prepare the event provider to run. This often involves setting information about the event source that the event provider monitors and the event class that defines the events that the event provider creates.

The Initialize method is called when the provider host starts running. The event provider performs initialization and returns as soon as initialization completes. The provider host always calls Initialize before calling the Run or Terminate method.

Ejemplo

For an example of how to implement the Initialize method, see the IEventProvider topic.
