Tim,

Is there a way to creating second TDBISAMTable cursor that is an exact
duplicate of another including any range? I can get the table info & the
filters copied, but don't know how to copy the range.

Something like:

function CloneCursor(ATable: TDBISAMTable): TDBISAMTable;

begin
  Result := TDBISAMTable.Create(ATable.Owner);
  Result.TableName := ATable.TableName;
  Result.DatabaseName := ATable.DatabaseName;
  Result.Filter := ATable.Filter;
  Result.Filtered := ATable.Filtered;

  (*
  HOW DO I COPY THE RANGE?
  *)
end;

Or will I have to keep track of the range I set in the first table &
then reproduce it when I make the cloned cursor?

Thanks,

Sean

You could try using EditRangeStart and EditRangeEnd - they will give you
FieldByName() access to the fields that are assigned values in the current
range.  You'll have to then go ahead an call ApplyRange again to keep the
existing range set, but that may or may not matter.

Tim,

Will the ApplyRange call change the record position in the dataset? For
that matter, does apply range always automatically move the cursor to
the first record of the range?

Thanks,

Sean

Possibly.

Yes.
