Hi Bob,

Thanks for replying.
I've read the posts and think I almost understand what is happening/not 
happening.  (Pity I put __ in my google search for stdcall/cdecl)

Yes it does.

#ifdef __cplusplus
extern "C"{
#endif
__declspec(dllimport) mystruct * __stdcall Function(void);
#ifdef __cplusplus
}
#endif

Previously I didn't have the #ifdef cplusplus as I am not using any c++ 
but I've added it in anyway.

I tried this but no joy. Same error _Function unresolved.

I've tried this but am missing something.

What I did was create a .def file using impdef.  The file has entries 
such as
Function = _Function@0

So then I included it in my project, but it made no difference.

The second reference refers to a lib command to create the .lib file 
from the .def.
What is this for Borland ?  I tried 'lib' but this picked up a lib 
command for another compiler I have installed, and the creation of a 
.lib from the .def is invalid for this command.  Or if it is the correct 
command, where does it live ?  I looked in CodeGear ... \bin and could 
not find an exe that seemed appropriate.  Ihave one in a VStudio 8 
directory but as I don't have Vstudio 8 installed it won't run. (Think 
these are there because of MSDN stuff).

It looks like Jeff ended up using cdecl instead of stdcall.
