missing methods for TDbf?

Hi,
I have noticed that some methods of TDbf (according to the TDbf pdf
manual) are not available to me, although I have db, dbf and
dbf_common in the uses clause.
For example, EmptyTable is not available.
Why?

You do understand that EmptyTable is a method of TDbf? So you have to
do ADbf.EmptyTable?

Of course.
But it is not there, as well as some other methods mentioned in TDbf
manual....

I drop a TDBF component on the form and put emptytables in an event
handler. The following code compiles for me using fpc 2.2.2 on
windows. I can't explain why you can't.

Code: [Select]unit Unit1;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics,
Dialogs,
  dbf;

type

  { TForm1 }

  TForm1 = class(TForm)
    Dbf1: TDbf;
    procedure FormCreate(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end;

var
  Form1: TForm1;

implementation

{ TForm1 }

procedure TForm1.FormCreate(Sender: TObject);
begin
  Dbf1.EmptyTable;
end;

initialization
  {$I unit1.lrs}

end.
[/code\

Hm, Could it be due to TableLevel property?

Such a property may cause problems at run time, but not during
compilation.

Do you have an old tdfb unit somewhere in your compiler-patch? And are
you sure it's the compiler which is complaining, or only the code-
completion?
