이부분이 남상훈님이 답변해주신건데..

이것만으로는 PARAM태그가 먹히질 않고요..;

class ATL_NO_VTABLE TPIRCMainImpl:
  VCLCONTROL_IMPL(TPIRCMainImpl, PIRCMain, TPIRCMain, IPIRC, DIID_IPIRCEvents),
  public IPersistPropertyBagImpl〈TPIRCMainImpl>,
  public IObjectSafetyImpl〈TPIRCMainImpl, INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA>


이렇게-_-하시고

BEGIN_COM_MAP(TPIRCMainImpl)
  VCL_CONTROL_COM_INTERFACE_ENTRIES(IPIRC)
  COM_INTERFACE_ENTRY_IMPL(IPersistPropertyBag)
  COM_INTERFACE_ENTRY(IObjectSafety)
END_COM_MAP()

이렇;게 하신후

BEGIN_PROPERTY_MAP(TPIRCMainImpl)
  //PROP_PAGE(CLSID_PIRCPage)
  PROP_ENTRY("Server", 16, CLSID_PIRCMain)
END_PROPERTY_MAP()

여기까지 해야.. 잘되는군요;
