typedef struct tagSTRUCTAx
{
      // members;
}
STRUCTAx;


#include "AfxTempl.h"


CArray<STRUCTAx, STRUCTAx> m_arAx;


You can use CArchieve for saving this into a file also

typedef struct tagSTRUCTAx
{
     HANDLE hBlob;
     bool bBool;
}
STRUCTAx;

#include "AfxTempl.h"


in the class header ActiveXCtl.h

CArray<STRUCTAx, STRUCTAx> m_arAx;


void CActiveXCtrl::DoPropExchange(CPropExchange* pPX)
{
      ...

      STRUCTAx sSTRUCTAx;

      PX_Blob(pPX, _T("YourProperty"), sSTRUCTAx.hBlob);

      m_arAx.Add(sSTRUCTAx);
      
      ...
}
