DLL

DLL

I'm providing the FORTRAN computational DLL for a program written by VB programmers. Part of their main program includes a VB DLL they use as a container for a significant amount of information read from an Access database. We have been passing the information to the FORTRAN DLL as parameters and it all works.
However, do you know if there is any way I can access the existing instance of the VB DLL they have already populated with information?
Or do you have any other suggestions on passing a large amount of information between a VB calling program and FORTRAN DLL?
Thanks!
