Managed C++ wrapper problem

Hi all

I was wondering if anyone has had a problem writing a thin wrapper in managed C++.

I am calling a managed C++ DLL from a .Net program from which I feed in all the market data and trade information.

However all the functions always return 0 (no error returned) so I tried creating a very simple static function that is an exact copy/paste from the main function in EquityOption.cpp sample that comes with the source and I still always get zero values returned. Running the pure C++ sample retults in the correct values.

Any ideas?

Best regards,

Ragnar

I don't know much about managed c++, but I wrote QuantLib code in an unmanaged
c++ dll and was able to send it to a .net form. How are you passing back
information?
