Hi,
Is there any sample codes or documents about how to send and receive the
messages between C++ and C# applications? For instance, I have a C++ dialog
application and C# dialog application running on same computer, how do I
transfer data back and forth between these two?
Thank you very much
Best regards,
Anthony

You can create a managed C++ wrapper for your DLL or use COM or use interop
to import DLL functions.
In the latter two cases marshalling will be a big issue and you may have to
create manages structs that mimic the layout of your C++ structs.

There are a lot of options you can choose from. Named pipes, shared
memory, DDE, remoting... Depends on your particular need.

Quick googling gave the following:

Named pipes:

You can choose virtually any IPC (interprocess communication) technology
Win32 has. I would probably implement both "ends" in one language (C++), and
use an MC++ wrapper from C#, but you can probably do the same using
P/Invoke.

Have a look at:
http://msdn.microsoft.com/library/de...unications.asp

Assuming the C++ application is managed, you can of course use .NET
remoting.
