ExpandEnvironmentStrings

Syntax:: WshShell.ExpandEnvironmentStrings (strString)
strString: Receives a string containing one or more environment variables.

The ExpandEnvironmentStrings method expands the environment variables in a string 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.

Examples

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.

Explanation:

This VBScript code illustrates the behavior of this method.
