Propriedades

  Nome Descrição
Propriedade pública ActionAtEvent Determines how the WmiEventWatcherTask responds when the task receives a Windows Management Instrumentation (WMI) event.
Propriedade pública ActionAtTimeout Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
Propriedade pública AfterEvent Determines how the WmiEventWatcherTask responds when the task receives the specified Windows Management Instrumentation (WMI) event.
Propriedade pública AfterTimeout Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
Propriedade pública DebugMode A Boolean indicating whether WmiEventWatcherTask should check if breakpoints are enabled.
Propriedade pública ExecutionValue Gets an Object that contains the results of the WmiEventWatcherTask task. (Substitui Task.ExecutionValue.)
Propriedade pública NumberOfEvents Gets or sets the number of Windows Management Instrumentation (WMI) events for which the WmiEventWatcherTask should watch.
Propriedade pública 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.
Propriedade pública Timeout Gets or sets the number of seconds the task should wait to receive a Windows Management Instrumentation (WMI) event before timing out.
Propriedade pública Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (Herdado de Task.)
Propriedade pública WmiConnection Gets or sets the name of the WMIConn class used by the WmiEventWatcherTask task.
Propriedade pública WqlQuerySource Gets or sets the source of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiEventWatcherTask.
Propriedade pública 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
Método público AcceptBreakpointManager Passes a BreakpointManager reference to the WmiEventWatcherTask task. This method is called by the runtime and is not used in code.
Método público CanUpdate *** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Herdado de Task.)
Método público Equals Determines whether two object instances are equal. (Herdado de DtsObject.)
Método público Execute Runs the task. (Substitui Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object).)
Método público GetConnectionID Gets a String containing the ID of the connection. (Herdado de Task.)
Método público GetConnectionName Gets a String containing the name of the connection. (Herdado de Task.)
Método público GetHashCode Returns the hash code for this instance. (Herdado de DtsObject.)
Método público GetType (Herdado de Object.)
Método público 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).)
Método público LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
Método público ResumeExecution Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
Método público SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.
Método público SuspendExecution Indicates that the executable needs to suspend. This method is called by the runtime engine.
Método público ToString (Herdado de Object.)
Método público 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.)
Método público 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.
