[Haskell] How to generate a dll?

[Andreas Marth]

Hallo!

I want to make my Haskell program usable from Visual Basic. What is the way
to go?
(I tried the way the user guide for ghc 6.4.2 describes but the resulting
dll was not stable.)
While I don't have any clues about language interoperation I guess it is a
task that is done
many times before. So I would appreciate any pointers.

Thanks for any help,
Andreas
