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 '\'.
#include "Ltdic.h"
L_LTDIC_API L_UINT32 L_DicomGetConvertValue(hDS, pElement, Destination, DestSizeInWords)
A DICOM handle.
Pointer to a DICOMELEMENT structure within the Data Set.
Character string to be updated with the string version of the value.
Size of the destination string buffer.
Number of characters in the "Destination" parameter.
Call this function twice. The first should have "Destination" set to NULL. This will provide you with the size of the string that will be stored in "Destination". Next, allocate the memory required for "Destination" and call this function again to update "Destination" with the string.
Win32, x64, Linux.
This example converts the value to a string and display it in a list-box control

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++)
