Propriétés

  Nom Description
Propriété publique ActionAtEvent Determines how the WmiEventWatcherTask responds when the task receives a Windows Management Instrumentation (WMI) event.
Propriété publique ActionAtTimeout Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
Propriété publique AfterEvent Determines how the WmiEventWatcherTask responds when the task receives the specified Windows Management Instrumentation (WMI) event.
Propriété publique AfterTimeout Determines how the WmiEventWatcherTask responds when the task times out without receiving the specified Windows Management Instrumentation (WMI) event.
Propriété publique DebugMode A Boolean indicating whether WmiEventWatcherTask should check if breakpoints are enabled.
Propriété publique ExecutionValue Gets an Object that contains the results of the WmiEventWatcherTask task. (remplace Task. . :: . .ExecutionValue.)
Propriété publique NumberOfEvents Gets or sets the number of Windows Management Instrumentation (WMI) events for which the WmiEventWatcherTask should watch.
Propriété publique 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.
Propriété publique Timeout Gets or sets the number of seconds the task should wait to receive a Windows Management Instrumentation (WMI) event before timing out.
Propriété publique Version *** Member deprecated; see Remarks. ***    Returns the version of the task. This property is read-only. (hérité de Task.)
Propriété publique WmiConnection Gets or sets the name of the WMIConn class used by the WmiEventWatcherTask task.
Propriété publique WqlQuerySource Gets or sets the source of the Windows Management Instrumentation Query Language (WQL) query to be executed by the WmiEventWatcherTask.
Propriété publique 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.

Méthodes

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

Notes

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 Tâche Observateur d'événement WMI.
