Can you be a bit more specific on what compiler you are using??

It depends on the compiler You are using :
each one has his own naming convention.

But You can declare whole class as __export
and leave DEF file default.

#ifdef __DLL__
#define MYCLASSDEC __export
#else
#define MYCLASSDEC __import
#endif

class MYCALSSDEC MyClass
 {
   .....

 } ;

After linking DLL, make LIB file for it ( by IMPLIB utility ) and link LIB file to EXE You are callin DLL from.

It works for BC++ & VC++

Another way to do it :

Make outclass function, what calls class memeber function :

extern "C"
{
 int FAR PASCAL __export MyCallFunc ( ... )
  {
    return my_class.MemeberFunc ( ... ) ;
  }
}

MyCallFunc can be defined as EXPORT in DEF file.

Hope, it helps.
