Description

Indicates that subsequent assignments to field values specify the start of the range of rows to include in the dataset.

Call SetRangeStart to put the dataset into dsSetKey state, erase any previous start range values, and set them to NULL. Subsequent field assignments to FieldByName specify the actual set of starting values for a range.

After assigning start-range values, call ApplyRange to activate the modified range.
