Summary

Fills the VALUEDATERANGE structure, with the date range information stored in the Value Field of the specified element.

Syntax

#include "Ltdic.h"

L_INT LDicomDS::GetDateRangeValue(pElement, nIndex, pValue)

Parameters

pDICOMELEMENT pElement

Pointer to a DICOMELEMENT structure within the Data Set.

L_UINT32 nIndex

Index value that indicates which value to retrieve when more than one value is stored in the Value Field. The index is zero-based.

pVALUEDATERANGE pValue

Pointer to a VALUEDATERANGE structure that will be filled with the date range value.

Returns

Value	Meaning
0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

This function can be called only if the Value Representation of the Data Element is VR_DA. For more information about Value Representations, refer to Default Value Representation Table.
