Eigenschaften

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

Methoden

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

Hinweise

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.
