L_UINT32 nCount

Value that indicates the number of values to set in the Value Field. If you want to set multiple values in the Value Field, put all the string values in pValue and set nCount to the appropriate number.

L_UINT32 uCharacterSet

Character set to use when inserting the input string. Possible values are:

Value	Meaning
DICOM_CHARACTER_SET_DEFAULT	Default repertoire (the default repertoire for character strings in DICOM), better known as ASCII
DICOM_CHARACTER_SET_LATIN_ALPHABET_NO_1	Latin alphabet No. 1

Comments

To set the string value(s) of a Data Element using default DICOM character set (DICOM_CHARACTER_SET_DEFAULT), use L_DicomSetStringValue2.

Note: You must allocate the memory for pValue.

If you want to set more than one value in the Value Field of the Data Element, put all the string values in pValue and set nCount to the corresponding number of entries. For example, if you wish to set three string values in the Value Field of the Data Element, put all three strings in pValue, separated by the "0" delimiter and set nCount to three. For example, the illustration below shows a character string, containing three strings separated by the 0 delimiter.

For more information on required delimiters between multiple values, refer to An Overview of the DICOM File Format and the DICOM Standard.

If more than one value is stored in the Value Field of the Data Element, you must set all values at the same time.

This function can be called only if the Value Representation of the Data Element is VR_AE, VR_CS, VR_LO, VR_LT, VR_SH, VR_ST, VR_UI, VR_UT, or VR_PN. For more information about Value Representations, refer to Default Value Representation Table.
