Calling FTN95 from Visual studio.

I am making a large application with VB. However, there is a numeric core that VB is simply too slow to execute. The FTN95 subroutine has no arguments (everything is retrieved from disk). I don't really understand how to integrate the FTN into visual studio.

Should one form a .dll of the FTN routines using the .Net option in the compiler?

You can access an FTN95 dll from VB but it would probably be Win32 rather than .NET and you don't necessarily need Visual Studio to create the dll.

Thanks. You have been very helpful
