2. In the .h file, define a macro similar to below
// The following ifdef block is the standard way of creating macros which
// make exporting from a DLL simpler. All files within this DLL are compiled
// with the __GXDLCODE_EXPORTS__ symbol defined on the command line. This
// symbol should not be defined on any project that uses this DLL. This way
// any other project whose source files include this file see GXDLCODE_API
// functions as being imported from a DLL, whereas this DLL sees symbols
// defined with this macro as being exported.
#define GXDLCODE_API __declspec(dllexport)
#define GXDLCODE_API __declspec(dllimport)

class GXDLCODE_API MyClass : public CDialog
// your class code here
