Exporting in a DLL

Programm3r

Hi all, Ok, this might be a stupid question but, here goes: Lets say you have a class in your DLL. And this class has a couple of functions that will be exported. Is it nessacery to export the class? I.E.

#ifdef UTILITY_EXPORTS
#define UTILITY_API __declspec(dllexport)
#else
#define UTILITY_API __declspec(dllimport)
#endif

class UTILITY_API test
{
public:
  int function1();
};

DEF File:

LIBRARY Utility
DESCRIPTION "Export Some Symbols."
EXPORTS
test @1
function1 @2

Thanx in advance

you need to export that class, not its functions.

Thanx for reply.. And one would be able to refernce those functions then, when exporting just the class?

To export a class from a dll is only possible from MFC-Class-DLL to MFC-Application. (or Microsoft Specific) To export a class isn't C++ standard. HTH Frank

No, I haven't tried ! ... But thank you for the help. But now that I know what to do, I'll try. :)

Wrong. You can export a class from any type of DLL. Whether you can use that class or not, depends entirely on the compiler/linker you use to link to the DLL.
