C / C++ / MFC

DISPCONTAINERCELLINFO pCellInfo;
m_ImageViewer.GetAnnotationContainer(pCellInfo->nCellIndex, pCellInfo->nSubCellIndex, &PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);

Here is the API :
   L_INT GetAnnotationContainer(L_INT nCellIndex,L_INT nSubCellIndex,HANNOBJECT * PhAnnContainer,L_UINT uFlags);

I have this in .h file

typedef struct tagDISPCONTAINERCELLINFO
{
   L_UINT uStructSize;
   L_HDC  hDC;
   L_INT  nCellIndex;
   L_INT  nSubCellIndex;
   RECT   rcRect;
   RECT   rcBitmapRect;
   L_INT  nX;
   L_INT  nY;
}
DISPCONTAINERCELLINFO, * pDISPCONTAINERCELLINFO;

DISPCONTAINERCELLINFO pCellInfo;
m_ImageViewer.GetAnnotationContainer(pCellInfo->nCellIndex, pCellInfo->nSubCellIndex, &PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);

I've declared a protected variable in a base class. I've assigned value and print the variable in a derived class. It prints correctly. I've printed the same variable inside another derived class. But it prints nothing. How to print the variable that is altered inside another derived class?
