Propriedades

	Nome	Descrição
	ActionAtEvent	Determines how the WmiEventWatcherTask responds when the task receives a Windows Management Instrumentation (WMI) event.
	ActionAtTimeout	Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
	AfterEvent	Determines how the WmiEventWatcherTask responds when the task receives the specified Windows Management Instrumentation (WMI) event.
	AfterTimeout	Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
	DebugMode	A Boolean indicating whether WmiEventWatcherTask should check if breakpoints are enabled.
	ExecutionValue	Gets an Object that contains the results of the WmiEventWatcherTask task. (Substitui Task. . :: . .ExecutionValue.)
	NumberOfEvents	Gets or sets the number of Windows Management Instrumentation (WMI) events for which the WmiEventWatcherTask should watch.
	SuspendRequired	Gets or sets a Boolean that indicates if tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
	Timeout	Gets or sets the number of seconds the task should wait to receive a Windows Management Instrumentation (WMI) event before timing out.
	Version	*** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (Herdado de Task.)
	WmiConnection	Gets or sets the name of the WMIConn class used by the WmiEventWatcherTask task.
	WqlQuerySource	Gets or sets the source of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiEventWatcherTask.
	WqlQuerySourceType	Gets or sets a QuerySourceType value that indicates the source type, such as file connection or a variable, of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiEventWatcherTask.

Métodos

	Nome	Descrição
	AcceptBreakpointManager	Passes a BreakpointManager reference to the WmiEventWatcherTask task. This method is called by the runtime and is not used in code.
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Herdado de Task.)
	Equals	Determines whether two object instances are equal. (Herdado de DtsObject.)
	Execute	Runs the task. (Substitui Task. . :: . .Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
	Finalize	(Herdado de Object.)
	GetConnectionID	Gets a String containing the ID of the connection. (Herdado de Task.)
	GetConnectionName	Gets a String containing the name of the connection. (Herdado de Task.)
	GetHashCode	Returns the hash code for this instance. (Herdado de DtsObject.)
	GetType	(Herdado de Object.)
	InitializeTask	Initializes the properties associated with the WmiEventWatcherTask task. This method is called by the runtime and is not used in code. (Substitui Task. . :: . .InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker).)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
	MemberwiseClone	(Herdado de Object.)
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
	SuspendExecution	Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	(Herdado de Object.)
	Update	*** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. (Herdado de Task.)
	Validate	Verifies that the task is properly configured. (Substitui Task. . :: . .Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging).)

Comentários

The class uses a WMIConn connection to connect to a server, execute a Windows Management Instrumentation Query Language (WQL) query against it, and wait for events associated with the query to occur. The task then provides notification as to whether a WMI event occurred. The WQL query can be provided directly, or a variable or file connection can be used to dynamically provide WQL queries at execution time.

Similarly, this class can use either a file connection or variable to receive the results of the WQL query. The output type of the WQL query results can also be specified.

For more information about the features of this task, see Tarefa Detector de Eventos do WMI.
