L_LTDIC_API L_UINT32 L_DicomGetConvertValue(hDS, pElement, Destination, DestSizeInWords)

HDICOMDS hDS;

a DICOM

pDICOMELEMENT pElement;

pointer to a DICOMELEMENT structure

L_TCHAR *Destination;

character string

L_UINT32 DestSizeInWords;

size of the destination string buffer

Converts the value of an element to a string and returns the number of characters in that string. Items in the string are separated by a '\'.

Parameter

Description

hDS

A DICOM handle.

pElement

Pointer to a DICOMELEMENT structure within the Data Set.

Destination

Character string to be updated with the string version of the value.

DestSizeInWords

Size of the destination string buffer.

Returns

Number of characters in the "Destination" parameter.

   L_TCHAR *q; 
   L_UINT32 nLength; 
   L_UINT32 nCount; 
   L_UINT32 i; 
   nCount = L_DicomGetCountValue(hDS, pElement); 
   nLength = L_DicomGetConvertValue(hDS, pElement, NULL, 0); 
   pszText = (L_TCHAR *)malloc(nLength * sizeof(L_TCHAR)); 
   L_DicomGetConvertValue(hDS, pElement, pszText, nLength); 
   for (i = 0, p = pszText; i < nCount; i++) 
   { 
      q = _tcschr(p, '\\'); 
      if (q != NULL) 
      { 
         *q++ = 0; 
      } 
      MessageBox(NULL, p, TEXT("Value"), MB_OK); 
      p = q; 
   } 
   free(pszText); 
   L_DicomFreeValue(hDS, pElement); 
   return DICOM_SUCCESS;
