IVF main calling C++ dll

[tom_c_lin]

Good Morning everyone,

I encountered a problem in calling C++ dll from IVF andhope someone will be able to give some suggestions. Thanks. I created a C++ dll using .NET Wizards (see Walkthrough: Creating a COM Server Using Wizards) and wrote a C++ main program to call the routines in dll. It works fine. But when I tried to link the dll with a IVF main program. The following error appeared:

fatal error LNK 1136: invalid or corrupt file

Does any of you know how to resolve this problem? Thanks and have a great day.

Good Afternoon everyone,

I have a comment on the message I posted this morning and hope some of you will share some of your experiences.

I think the reason that my IVF main program fail to link with the C++ dll is because the C++dll I used (created by .NET Wizards) is an 'managed code' and IVF program will only link with 'unmanaged' .NET C++ libraries. Any thoughts or comments? Thank and have super evening.

You're right that if you built a "managed" DLL, you can't call it directly from unmanaged code. You could use the "Fortran Module Wizard" to generate interfaces for it, but it would be better to build an unmanaged DLL from your C++ code.
