Error 70, Error 91 and error list separator

[jenergy]

Hello!
I've got this problem:

I created a folder with visual basic

When I try to delete it(and only that dir...) with this code:

>Dim fso As FileSystemObject
>...
>fso.DeleteFolder defaultInstallFolder & "Config", True

I obtain "Permission denied", just like if folder is in use.. but it's in use from vb!
(The utility "Who lock me?" tells me that it's locked form vb)

I tried to change current dir to parent dir of folder to delete, but i didn't help.

If I try to delete directory just after have created, in another piece of code, the error changes:

"Object variable or With block variable not set"

I've read that perhaps it's a Microsoft bug, to solve using properties, so I made:

>Dim fso As FileSystemObject
> ...
> Public Property Get ob() As FileSystemObject
> ob = fso
> End Property

> Public Property Let ob(Object As FileSystemObject)
> fso = Object
> End Property

and tried to delete it using:

>Get ob.DeleteFolder defaultInstallFolder & "Config", True


but the error now is "Expected: list separator"

or I tried:

>Get ob().DeleteFolder defaultInstallFolder & "Config", True
>...
>Dim fso2 As FileSystemObject
>fso2 = Get ob (compile error)

The question is: HOW THE HELL CAN I DELETE THE FOLDER ? :-)

I can't understand the problem, I can easily delete other directories created in the same code 2-3 lines above, but THAT directory not. And neither in different Pcs, same problem.
I can only use vbcce5..

Thank you for responses!!

Is there a running exe in the folder your trying to delete?

[jenergy]

I forgot to say it:
folder is empty!

Is it on a local hard drive or a network drive?

It's in a local drive, no network.

What OS is this? Have you checked the inheritable permissions?
