Calling a C++/CLI dll function from an MFC dll/exe

Hi,

I have a C++/CLI dll that have some methods that I need to use (or call)
from my legacy C++ application/dll created using Visual Studio 6.0.

Will really appreciate some suggestions on what are some of the ways to do
the above so that I can call the functions I wrote in C++/CLI (Visual Studio
2005) from my legacy application.

THanks

1 Create some callback function types
2 pass the pointer of your callback function in C++/CLI projects into your
MFC legacy application. Your callback function can call managed funtion in
the same project.

Can you upgrade to VS Net 2005? If so you can create a static class marked
unsafe that you can reference and call directly from your unmanaged code.
That static class can then call any other .Net code you need. I used this
method to build a Win32 dll wrapper around some .Net code for use in a
scripting language that could only call vanilla Win32 dlls.
