vb.net and remote web files

How can I load the file names from a remote web server via VB.net? I created
a virtual directory on a w2003 server and did a
Dir("http://test.com/testdir/*.*")
I also tried
Dir("http://test.com/testdir/")
but it returns no error, just an empty string. Is there another way to read
file names on web server via vb.net
I can enter the http path "http://test.com/testdir/" in the windows run box
and it returns a listing of the files in the web directory, but I cant find
a way to do it in vb.net..
Thanks

You can't do that with Dir("http://test.com/testdir/*.*"),
The file system won't redirect the folder to a http server.

You can write some code to download the files to local folder
first, then browse it.
