IWshEnvironment.NewEnum_ Method
« on: July 14, 2008, 10:40:00 PM »

The following code illustrates the use of the NewEnum_ method:

Code: [Select]
#INCLUDE "WSHOM.INC"

DIM pWsh AS IWshShell
DIM pWshEnv AS IWshEnvironment
DIM nCount AS LONG
DIM pUnk AS IUnknown
DIM pEnum AS IEnumVARIANT
DIM IID_IEnumVARIANT AS GUID
DIM i AS LONG
DIM celtFetched AS LONG
DIM vValue AS VARIANT

' Create an instance of Windows Script Host
pWsh = NEWCOM "WScript.Shell"
' Get a reference to environment collection
pWshEnv = pWsh.Environment
' Get the number of objects in the collection
nCount = pWshEnv.Count
' Get a reference to the collection's enumerator
pUnk = pWshEnv.NewEnum_
pEnum = pUnk
FOR i = 0 TO nCount - 1
   pEnum.Next 1, vValue, celtFetched
   IF celtFetched = 0 THEN EXIT FOR
   STDOUT VARIANT$(vValue)
NEXT
