I am getting a type mismatch error when attempting to use the
IHTMLElementRender inteface from VB6. I noticed that this interface does not

which was created as a "Class Library" using Visual Basic 2008 Express

Can anyone provide me with a simple example of the following:
1.) Writing a COM interface for a subroutine placed inside a "Class
Library" project using vb 2008 express edition.  I want to call the
subroutine inside the dll created during this step from excel vba code.

I'm looking for some suggestions here as a section of code is misbehaving
at only one site (2 machines) and works elsewhere. The code is part of a
multi-threaded ActiveX EXE. The exact same EXE is installed at several
sites.
