Examples

The following script illustrates the creation of an SWbemRefresher object and the addition of single object and enumerator SWbemRefreshableItem to it.

' Get some namespace connections
set cimv2 = GetObject("winmgmts:root\cimv2")
set default = GetObject("winmgmts:root\default")    

' Create a refresher
set refresher = CreateObject("WbemScripting.SWbemRefresher")

' Add a single object to the refresher.
' The @ is used because this is a singleton 
' system class so only one instance exists.
set item1 = refresher.Add (default, "__CIMOMIdentification=@").Object
MsgBox "WMI Version " item1
' Add an enumerator to the refresher.
' Note that the SWbemRefreshableItem.ObjectSet 
' property must be used to designate
' this as an object set rather than a single object.
set item2 = refresher.AddEnum (cimv2, "Win32_Process").ObjectSet

' Loop three times, refreshing the items

For I= 1 To 3
MsgBox "Refresh number " & I
refresher.Refresh

' Iterate through the collection of
' processes in item2 with name of wscript
    For each process in item2
        If process.name = "wscript.exe" then
        MsgBox "Process " & process.Name & _
           " Page Faults " & process.PageFaults
        End If
    Next 
Next

' Clear out the refresher
refresher.DeleteAll 

' The following should return 0
MsgBox "Number of items in Refresher after DeleteAll " _
    & refresher.Count
