Use the rowStates argument to specify the type of changes the new object should include.
This returned copy is designed to be merged back in to this original DataSet. Relationship constraints may cause parent rows marked Unchanged to be included. If no rows of the desired DataRowState are found, the GetChanges method returns a null reference (Nothing in Visual Basic).
