All Properties Method:  WshShell.ExpandEnvironmentStrings WshShell.ExpandEnvironmentStrings strString The ExpandEnvironmentStrings method expands the environment variables in strString and returns the resulting string. Environment variables are case-insensitive and are enclosed by a pair of % characters. If an environment variable in strString is undefined, then it is left unchanged. The following VBScript code illustrates the behavior of this method. Code: Set WshShell = CreateObject("WScript.Shell") strOriginalString = "Windows is installed in %WinDir%. %XYZ% is undefined." strExpandedString = WshShell.ExpandEnvironmentStrings(strOriginalString) WScript.Echo "Before: " & strOriginalString WScript.Echo "After: " & strExpandedString Output: Before: Windows is installed in %WinDir%. %XYZ% is undefined. After: Windows is installed in C:\WINNT. %XYZ% is undefined. Copyright 1999-2001 by Infinite Software Solutions, Inc. All rights reserved. Trademark Information
