object

WshShell object.

strString

String value indicating the name of the environment variable you want to expand.

The ExpandEnvironmentStrings method expands environment variables defined in the PROCESS environment space only. Environment variable names, which must be enclosed between "%" characters, are not case-sensitive.

The following code expands the Windows Directory environment variable and displays it:

Visual Basic Script	Copy Code
set WshShell = WScript.CreateObject("WScript.Shell") WScript.Echo "WinDir is " & WshShell.ExpandEnvironmentStrings("%WinDir%")

JScript	Copy Code
var WshShell = WScript.CreateObject("WScript.Shell"); WScript.Echo("WinDir is " + WshShell.ExpandEnvironmentStrings("%WinDir%"));
