This example displays the name of the last item in the current level.

L_INT LDicomIOD_GetLastExample_1() 
{ 
   pDICOMIOD   pElement; 
   pDICOMIOD   pLast; 
 
   pElement = LDicomIOD::Find(NULL, TAG_PATIENT_NAME, IOD_TYPE_ELEMENT, FALSE); 
   if (pElement != NULL) 
   { 
      pLast = LDicomIOD::GetLast(pElement, TRUE); 
      ::MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK); 
   } 
 
   return DICOM_SUCCESS; 
} 
 
/* This example displays the name of the last item in the IOD table */ 
 
L_INT LDicomIOD_GetLastExample_2() 
{ 
   pDICOMIOD pLast; 
 
   pLast = LDicomIOD::GetLast(NULL, FALSE); 
   if (pLast != NULL) 
   { 
      ::MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK);
