Comments

If you have more than one value stored in the Value Field of the specified Data Element, you can retrieve one or more of those elements. For example, if the Value Field of the specified Data Element contains three Date-Time Range values, and you are only interested in retrieving the last two Date-Time Range values, set nIndex to 1 and nCount to 2. This tells the function to retrieve the Date-Time Range values starting at position 1 (the index is zero based) and retrieve two values. Therefore you would retrieve the values in positions 1 and 2 in the Value Field.

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