Can't get names of subfolders using ActiveXObject('Scripting.FileSystemObject') and JS

Question

I'm trying to get names of subfolders inside of a folder using JavaScript and Windows' ActiveXObject('Scripting.FileSystemObject') in my HTA-file:

var fso = new ActiveXObject('Scripting.FileSystemObject');
var subfolders = fso.GetFolder('D:\path\to\myfolder\').SubFolders;
for(var i = 0; i < subfolders.length; i++) {
    alert(subfolders[i].Name);
}

OR

var fso = new ActiveXObject('Scripting.FileSystemObject');
for(var subfolder in fso.GetFolder('D:\path\to\myfolder\').SubFolders) {
    alert(subfolder.Name);
}

But I get nothing in both cases. What's wrong?

Answer 1

Ok, I've found this solution:

var fso = new ActiveXObject('Scripting.FileSystemObject');
var e = new Enumerator(fso.GetFolder('D:\path\to\myfolder\').SubFolders);
for(;!e.atEnd();e.moveNext()) {
    alert(e.item().Name);
}
