L_TCHAR *Destination

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

   L_TCHAR* q; 
   L_UINT32 nLength; 
   L_UINT32 nCount; 
   L_UINT32 i; 
 
   nCount  = pDS->GetCountValue(pElement); 
   nLength = pDS->GetConvertValue(pElement, NULL, 0); 
   pszText = (L_TCHAR *)malloc(nLength * sizeof(L_TCHAR)); 
   pDS->GetConvertValue(pElement, pszText, nLength); 
 
   for (i = 0, p = pszText; i < nCount; i++) 
   { 
      q = wcschr(p, '\\'); 
      if (q != NULL) 
      { 
         *q++ = 0; 
      }
