The event is fired before an action that performs a scenario that goes to or opens some destination will be executed(). The IEvent interface should be cast to the IPXV_GotoActionEvent interface.
|Handled||VARIANT_BOOL||Specifies whether the event was handled. Marking the event as handled will cause the event sender to look at the event`s result and act accordingly based on the event type.|
|Result||PARAM_T||Specifies the result that will be used by the event sender when the event is marked as Handled. If the Result is not 0 then the action execution will be canceled.|
