Daniel,

One way to use ur old c++ code is to compile as a dll. In c#, you can access
the functions using "DllImport".

Unsafe c# is another way to use c++ code. Refer MSDN regarding that.

I used a managed C++ wrapper for my old C++ code.

In your solution add a managed C++ library.  Add your existing C++
source to the project and compile.  Once everything compiles, add
managed C++ classes to create the API that you want your C# code to see.

After doing this you will likely get a LNK 4243 warning.  Search for
this warning in your local MSDN docs or the MSDN website to find out how
to initialize the C run time library.

If you don't already know managed C++ you might want to use a Beta
version of VS 2005, or wait until it is released.  From what I here the
managed C++ syntax will change in VS 2005.

Another posibility is to use the Unix way.  Set up your C++ code as a
separate process.  Use sockets to communicate between the program
written in C++ and the one written in C#.  I was just reading "The Art
of Unix Programming" on the weekend, so havn't tried this technique yet.
