Moves to the next data element in the current segment.
SkipElement can be used to avoid providing a value for the current element in the current segment.
If the element already has a value (such as one provided by default by the class), said value will not be overwritten.
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
