I did exactly the steps author listed in early binding section to call a vb dll from asp.net page writen in C#. I got Server Error "The specified module could not be found" when running on the localhost, and I got different server error:"System.UnauthorizedAccessException: Access is denied." after I deployed it to the test server.

I got the same error? Have you figured out how to fix it? Thanks a lot!
