Question

Im using ActiveXObject and I am using the FileExists function. I was doing some testing to see if it worked. I finally was able to show true.

JavaScript

var shellActiveXObject = new ActiveXObject("Scripting.FileSystemObject");        
alert(shellActiveXObject.FileExists('C:/Windows/notepad.exe'))

I want to replace the C:/Windows with an environment variable like %windir%.
When I do that, it reads it as false. How can I make it so it inteprets the environment variable?

I used Wscript.Shell and used it's ExpandEnvironmentStrings method.

JavaScript

var objshell = new ActiveXObject("Wscript.Shell");
var strfolderpath = objshell.ExpandEnvironmentStrings("%windir%");

It expanded it correctly
