I have a .NET/Com-Interop assembly that is used in VB6/VBA6, however I
have
a customer who wants to call it from C (_not_ C++ AFAICS). The compiler
looks
and behaves pretty compatibly with older .dll files.

I have no real idea at present what the systactical requirements would be
to
build the interface to this .dll as everthing I see descripes the VB, C++,
C#
J#, intrfaces, but nothing seems to show any kind of base C examples.

What syntax/constructs/etc. would I use for this?

Oh .. "upgrading to a recent VC++" is not an ioption. This is an
interpreter/compiler that's embedded within a large application for
building
what equate to scripts or macros within the application.

Hi,
Registering the assembly for COM interop is step 1. If you can use them in
VB6 that should be OK.

For step 2: I refer you to www.codeproject.com and go to the COM section.
there is a number of articles titled: 'COM in plain C'
These articles are of a good quality, though never read the in detail
myself.
