Sharing Fortran common blocks with VB.net

[islayrod]

I have a large mixed language project (legacy code)that needs to be converted from Compact Visual Fortran and Microsoft Visual C++ to .NET. In the legecy code, several large fortran common block are shared between fortran code and the C++ code using global structures. I've been told that there may beproblems with tring to do this (sharing common blocks/data structure) in VB.NET or even C++.NET.

Have anyone ever done this? I would apprieciate any examples dealing with this and any information on how it is done.

Thanks,

Islay

I doubt that this can be done although you might be able to try memory mapping but this is usually used for interprocess sharing. If you want to share intraprocess between Fortran and VB you have to pass the data as arguments to a sub or function.
