Fortran file in visual c++ 6.0

Hello everybody.

I am trying to do a c++ program which calls a fortran function.

I am doing a dialog based program.

I got this errors:

Linking...

Can anyone help me.

Thanks a lot

Did you change any default settings?

I've changed a lot the default settings :-(

In the fortran tab, doing multi--threaded library , dll.

The program compiles without errors.

Thanks for your reply.

Do anyone have an example of calling a fortran function wich is in a *.for file from a dialog based class?

THANKS

You'd have to have the Fortran source compiled to a DLL first. It's not possible to call a function from a source file in other language.
