  const sValue: string): Boolean;
var

  bmPos: TBookMark;
  bFound: Boolean;
begin
  Locate := False;
  bFound := False;
  if not oTable.Active then Exit;
  if oTable.FieldDefs.IndexOf(oField.FieldName) < 0 then Exit;
  bmPos := oTable.GetBookMark;
  with oTable do
  begin
    DisableControls;
    First;
    while not EOF do
      if oField.AsString = sValue then
      begin

        Break;
      end
    else
      Next;
