Returns an environment variable's expanded value.
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:
set WshShell = WScript.CreateObject("WScript.Shell") WScript.Echo "WinDir is " & WshShell.
var WshShell = WScript.CreateObject("WScript.Shell");
WScript.Echo("WinDir is " + WshShell.ExpandEnvironmentStrings("%WinDir%"));
