CanEnumInvertSense Property

Exchange Server 2003

CanEnumInvertSense Property

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

The CanEnumInvertSense property, when True, specifies that the queue can enumerate messages that it has waiting for transmission that do not match the criteria requested. For example, requesting the oldest messages while inverting the request sense would return the newest messages. The CanEnumInvertSense property corresponds to the thirty-second bit (0x80000000) of the MsgEnumFlagsSupported property. The CanEnumInvertSense property is read-only.

Applies To

The CanEnumInvertSense property is a member of the ExchangeQueue Class.

Instance Path

The CanEnumInvertSense property appears on instances of the \\COMPUTERNAME\ROOT\cimv2\applications\exchange:ExchangeQueue class.

MOF Syntax

boolean CanEnumInvertSense;

Qualifiers

This property has no qualifiers.

Remarks

When CanEnumAll is True, the queue contents can be listed in the Exchange System Manager. The Microsoft ExchangeWMI classes cannot be used to list the queue contents.

VBScript Example

The following example shows how to retrieve a list of ExchangeQueue instances, and how to retrieve the CanEnumInvertSense property for each instance.

'===============================================================
' Name:      ShowQueue_CanEnumInvertSense
' Purpose:   Display each Queue found for the Exchange server,
'            and show the CanEnumInvertSense property on the
'            ExchangeQueue objects.
' Input:     strComputerName [string] the computer to access
' Output:    Displays the name of each Queue and the
'            CanEnumInvertSense property.
'===============================================================
Public Sub ShowQueue_CanEnumInvertSense ( strComputerName )

Const cWMINameSpace = "root/cimv2/applications/exchange"
Const cWMIInstance = "ExchangeQueue"

Dim strWinMgmts              ' Connection string for WMI
Dim objWMIExchange           ' Exchange Namespace WMI object
Dim listQueues               ' ExchangeQueue collection
Dim objExchangeQueue         ' A single ExchangeQueue WMI object

' Create the object string, indicating WMI (winmgmts), using the
' current user credentials (impersonationLevel=impersonate),
' on the computer passed to the function in strComputerName, and
' using the CIM namespace for the ExchangeQueue provider.
strWinMgmts = "winmgmts:{impersonationLevel=impersonate}!//" & _
   strComputerName & "/" & cWMINameSpace
'
' Get an object using the string you just created.
Set objWMIExchange =  GetObject(strWinMgmts)
'
' The Resources that currently exist appear as a list of
' ExchangeQueue instances in the Exchange namespace.
Set listQueues = objWMIExchange.InstancesOf(cWMIInstance)
'
' Were any ExchangeQueue Instances returned?
if (listQueues.count > 0) then
  ' If yes, do the following:
  ' Iterate through the list of ExchangeQueue objects.
  For each objExchangeQueue in listQueues
     '
     ' Display the value of the LinkName property.
     WScript.echo "LinkName = " & _
      "[" & TypeName(objExchangeQueue.LinkName) & "] " & _
       objExchangeQueue.LinkName
     '
     ' Display the value of the CanEnumInvertSense property.
     WScript.echo "    CanEnumInvertSense                         = [" & _
       TypeName(objExchangeQueue.CanEnumInvertSense) & "] " & _
      objExchangeQueue.CanEnumInvertSense
     '
     ' Move to the next ExchangeQueue.

  ' display that.
  WScript.Echo "No ExchangeQueue instances were returned."
