Les and Folks, I have some useful information on this I hope.
I had to compile the C# app as platform x86 to consume the Borland XE5 C++
DLL's functions, but I'm guessing the author just used the defaults and
didn't specifically force me to do that.
The C++ function was defined as __declspec(dllexport) and the managed
runtime Exception implied I was "almost" calling the function. This simple
change made it work okay:
[DllImport("foo.dll", CallingConvention=CallingConvention.Cdecl)]
Bring backa memory from the 1990s. We still have to check that strings are
marshalled back-and-forth correctly.
