I have developed a C# application/dll which has some functions that I
would
like to use as callback functions from my VC++ 6.0 application/dll.
Often the easiset thing to do is to put a shim netween them.
The best thing about the managed versions of C++ (MC++ and C++/CLI) is that
a module written in a managed version of C++ can contain both native and
managed classes. So, your VC6 application can call free functions in a
managed DLL, which then calls managed functions in C++ which can consume
your C# classes because managed versions of C++ and C# share the same object
model.
At some level the problem is reduced to figuring out how you can have a
C-style procedural interface to a C++ class.
Another option is to use COM. The RegAsm (register assembly) utility
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cptools/html/cpgrfAssemblyRegistrationToolRegasmexe.aspcan be used to create a COM wrapper around your C# class.That done, the problem is reduced to consuming a COM object.Regards,Will
