Set the upper display index of the Dataset.
BOOL SetUpperBound( int nUpper )
Returns TRUE on successful exit and FALSE on failure.

Set the upper display index of the Dataset range. Index values are 0 based offsets so use SetUpperBound(-1) to display no rows. SetUpperBound is supported only for Datasets (not vectors) while GetUpperBound is supported for all vectorbase derived objects. This allows for creation of more general purpose functions that can take vectorbase objects as arguments in place of Dataset objects. Essentially, the upper bound can be read but not written for vectors. SetUpperIndex is a synonym for SetUpperBound.
