Re: exporting classes in a DLL

The class declaration header file should look something like this :-

#ifdef EXPORTSCLASS
#define EXPORTCLASS_API __declspec(dllexport)
#else
#define EXPORTCLASS_API __declspec(dllimport)
#endif

class EXPORTCLASS_API CMyClass
{
public:
//...
};

When you use this in the DLL project, define EXPORTSCLASS, but refrain from
doing so in the EXE project where you call this dll.
