Peter,
I appologize if there was a miscommunication... I know this thread is
getting long, so let me reiterate the issue, taking a step back to explain
where I am.

I downloaded the samples off the Microsoft KB#812404, so if you have not
already done so, please start with those. I then modified the files as you
recommended on 6/15/04. In the ftp.vb file (from the KB example) there is a
variable to define ftp.currentdirectory. This appears to be the location of
your "directoryname" variable. As I have stated, I have been changing this
to different values including "", "/" and "\", in an attempt to access a
directory listing of the base directory. None of these are working. I am
attaching an updated output file to the end of this message for your review
as the other one is old. Please let me know if you can tell me anything
based on this output..

The goal here is to return a list of all the files and directories in an FTP
site on one of my servers. I can get the file list by typing ftp://
Address> into the address bar in IE6, so I know the site is configured
properly. What I need now is to get the list of directories and files
through code.

Scott
