DIWbemServices.ExecNotificationQueryAsync

[This is preliminary documentation and subject to change.]

The DIWbemServices.ExecNotificationQueryAsync method performs the same task as DIWbemServices.ExecNotificationQuery, except that events are supplied to the specified response handler until you call CancelAsyncCall to stop the event notification.

DIWbemServices.ExecNotificationQueryAsync(
  [in] QueryLanguage As String,                
  [in] Query As String,                        
  [in] lFlags As Long,                       
  [in] pCtx As Object,                 
  [in] pResponseHandler As Object       
) As Long
 

Parameters

QueryLanguage

A string containing one of the query languages supported by CIMOM. This must be "WQL" for the WBEM Query Language.

Query

A string containing the text of the event-related query. This cannot be vbNullString.

lFlags

Reserved. It must be zero.

pCtx

Typically NOTHING. Otherwise, this is a DWbemContext object required by the dynamic class provider that is producing the class instances. The values in the context object must be specified in the documentation for the provider in question.

pResponseHandler

The caller's implementation of DIWbemObjectSink. This handler receives the objects in the query result set as they become available. To stop receiving events, you must call DIWbemServices.CancelAsyncCall by using the same object for pResponseHandler.

For a detailed explanation of this parameter, see Asynchronous Methods.

Return Values

For more information on return values see Visual Basic error handeling and return values

Other error codes return to the object sink specified by the pResponseHandler parameter.
