Item number in a collection?

[news.microsoft.com]

Hi

I want to reverse a folder listing, can I referre to a collection with a
item number like in arrays?

ex:
set fs=Server.CreateObject("Scripting.FileSystemObject")
set fo=fs.GetFolder(smp)
for each subfld in fo.subfolders
..
..
next

can I do the FOR statement reverse without putting all folder names into an
array.

I don't quite follow. What is in

..
..

?

I think what he wants to do is something like:
Set subFolders = fo.Subfolders
For i = 0 to subFolders.Count
response.write subFolders(i).Name
Next

which you cannot do with the subfolders collection.

instead of

for each x in fo.subfolders
response.write x.name
next

U right Ray, that is what I wanted.
Ok, no big problem, just takes longer to execute my code if I have to put
folder names into an array.

Why do you think using a "for each" statement is putting anything into an
array? It is not.

He doesn't. klæj wants to iterate through the subfolders in reverse order,
i.e., not the order they come out in the For Each loop. In order to do
this, klæj has to first iterate through the subfolders in their initial
order, while storing them into an array. Once the subfolders are in an
array, they can be iterated through in reverse order using step -1. klæj
was lamenting over the fact that doing this makes the code slower.

Oh, okay I too am lamenting.
