did you implement DoPropExchange ?
void CYourCtrl::DoPropExchange(CPropExchange* pPX) /*\L1\L2 $Workfile: KKOSetCtl.cpp $*/
 * Persistence support
 * This function does the persistent storage of propertys in VB component documents.
 * Returnvalue: void

      ExchangeVersion(pPX, MAKELONG(_wVerMinor, _wVerMajor));

      PX_String(pPX, _T("Property1"), m_Prop1, "");
      PX_String(pPX, _T("Property2"), m_Prop2, "");
      PX_Bool  (pPX, _T("Property3"), m_Prop3, TRUE);

But another problem is why when changed the value in property page,the values  did not present in VB's build-in Property Window immediately?
