Proprietà

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

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

Osservazioni

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 Attività Monitoraggio eventi WMI.
