CommandActivity Members

Include Protected Members
Include Inherited Members

Represents a digression in the dialog. A command is matched when the user speaks a phrase recognized by the command's grammar. It is different from a DialogEventActivity in that regard. A DialogEventActivity represents a system-initiated event in the dialog flow, while a CommandActivity represents a user-initiated event and the associated handler for the event. The CommandActivity provides the event-subscription data, and the children of the CommandActivity provide the handler logic for the event. Deriving from the CommandActivity is not supported, as it is used by other command activities.

The CommandActivity type exposes the following members.

Properties

	Name	Description
	Activities	(inherited from CompositeActivity)
	CallProvider	Gets or sets a CallProvider object that exposes different objects like the Call object, SpeechSynthesizer object, and the recognizers used in instant message or speech dialogs. (inherited from CommunicationsSequenceActivity)
	CanModifyActivities	(inherited from CompositeActivity)
	Description	(inherited from Activity)
	DesignMode	(inherited from DependencyObject)
	Enabled	(inherited from Activity)
	EnabledActivities	(inherited from CompositeActivity)
	ExecutionResult	(inherited from Activity)
	ExecutionStatus	(inherited from Activity)
	Grammar	Gets or sets the grammar used to recognize the input that triggers this CommandActivity. A Grammar object provides run time support for obtaining and managing speech grammar information.
	IsDynamicActivity	(inherited from Activity)
	Name	(inherited from Activity)
	Parent	(inherited from Activity)
	ParentDependencyObject	(inherited from DependencyObject)
	QualifiedName	(inherited from Activity)
	RecognitionResult	Gets the recognition result that triggered the command. A RecognitionResult object represents the result of the recognition engine on audio input.
	Site	(inherited from DependencyObject)
	UserData	(inherited from DependencyObject)
	WorkflowInstanceId	(inherited from Activity)
