Are you talking about VB6 or VB.NET?  If you had to add a reference, then
it is either a COM interface or a managed code class.  DLLs don't get in
through references -- they use the Declare statement.

COM interfaces are pretty easy to call in Python.  Calling managed code is
almost impossible right now.
