Sharing Global stuctures between VB.net and C++.net or C#.Net

[=?Utf-8?B?SXNsYXkgUm9kcmlndWV6IEpyLg==?=]

How do you share glogal data stuctures between VB.net and C++ or C# ?

Thanks,
Islay

You can do that via a memory-mapped file (p/invoke), for example.

Does this method require I/O to the disk every time a variable in the data
structure is accessed?

I'm look for something that will allow access to the variables in the
structure, as if they static to each of the routines (vb.net and C++). Parts
of the stucture has large buffers for DMA data that is not required on
disk,it only needs to be avalible in memory. Other variables are modified
dynamicaly in other threads and must be instantly avalible to other routines
in different threads.

Hi Islay,

I'm not familiar with Fortran, therefore my understanding of this issue
might not be complete. What was your previous approach? Do you mean shared
data section using "#pragma data_seg" in Visual C++? I think you can still
use this approach in .NET application, but only with managed C++ (C++/CLI),
you cannot do this for C# or VB.NET. See the last FAQ here:
