I have also came accros some posts where it is said to use CreateProcessAsUser function to launch the child process. But I could find a proper code to get the "Token Handle" to be used as a parameter to this function. Could you please help me in this area. ?

PS: If you like my Answers .. Please rate them ... That will give me a lot of confidence

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);
