Is it possible to combine Fortran and C# (data exchange) in WIN32 environment , or only using .NET ?
Klaus

[PaulLaidler]

Only .NET.

[MERO]

Is the same true for Fortran + C++ ?

FTN95 can be combined with ("unmanaged") C++ under Win32.

SLINK allows you to link object files created by either FTN95 or SCC.
A Plato project can contain both Fortran and C++ files.

Further to Pauls answer

depending on you problem and the complexity required

you can make Mixed C++ code, ie unmanaged and managed projects.

the unmanaged methods can then made to interface with WIN32 ftn95 and managed objects are visible to the .NET environment and C#. This is the preferred method of doing complex interop tasks in the .NET environment.

This structure could be use the ADO.NET classes to get data from a database to be passed to FTN95 code.

I have used these methods in both directions ie calling Win32 FTN95 DLL's from .NET applications and also FTN95 WIN32 projects calling .NET classes.

I was driven to this because I needed to use some antique win32 libaries in my ftn95 projects.

if you are using a C# calling program you could also use

System.Runtime.InteropServices

to call native WIN32 FTN95 libraries from C#

I can post a simple example of this

here

C# calling program --

using System;
using System.Runtime.InteropServices;


class Program
{
[DllImport("nativeftn95.dll")]
static extern void TOBECALLED();

static void Main(string[] args)
{
TOBECALLED();
Console.WriteLine("This is a C# string...\nPress any key");
Console.ReadKey();
}
}


nativeftn95.dll --- code


subroutine tobecalled
write(*,*) 'this is a WIN32 fortran dll string'
end subroutine


obviously the C# code needs to be able to find the the library if this method is used - the dllimport label contains the path to the native dll.


this interop structure appears to be missing from FTN95.net, I personally feel this should be added for the next version of FTN95, ie being able to call native libraries from FTN95.net without going via another .NET language.

DrTip is right. You can access managed C++ from a Win32 C++ project.
You could then access the result from a Win32 FTN95 project.
Not easy but possible.
