Just figure out , with help from some of my old delphi code how to use
database in lazarus and create fields. GREAT !!   but now its giveing
the warning that Tdbf is deprecated. oww. 

Now the question, whats the replacement for Tdbf
thats working the same with database creation.
As example i create it now this way, i dont look for linux
compatibility.

procedure TForm1.Button1Click(Sender: TObject);
begin
  With Dbf1 do
  Try
    Active := False;
    Filepath:=ProgramPath+DataDir+'\';
    //Databasename:=DBfile+DBExt;
    TableName := DBfile;

    with FieldDefs do
    begin
      Clear;
      Add('1' , ftFixedChar    , 20, False);
      Add('2' , ftFixedChar    , 20, False);
      Add('3' , ftFixedChar , 60, False);
    end;
    CreateTable;
    Active := True;
  Except
    { If an error occurs, the table is corrupt - create a new one }
    on EDatabaseError do
    begin
    end;
  end;
end;

The replacement is TDBF.

We're maintaining TDBF again, see
http://wiki.lazarus.freepascal.org/User_Changes_Trunk#TDBF_unit_deprec
ation_removed

If you run into problems, post on the forum and I'll have a look to
see if it can be fixed.

Edit: wiki tutorial/article with links to docs etc:
http://wiki.lazarus.freepascal.org/Lazarus_Tdbf_Tutorial

PS: Alternatives are sqlite or embedded firebird; both can be run with
the standard Lazarus/FPC SQLDB database components; both are cross
platform.
Of course, TDBF is native while you'd need driver .dll/.so libs for
the others.

Ok, thanks. Tdbf is what im useing. but still saw the deprecated
warning. but it can be some unit that gave the error to. it seems now
fine.

I love lazarus, and the old delphi 5 gui is no problem anymore to. it
feels ok.

TDBF has the deprecated warning in FPC 2.6.0 and 2.6.2, which are used
with Lazarus 1.0.x
These versions have been released as stable versions and cannot be
modified later on once they have been released, so the deprecation
warning still remains in them (but is deceiving in this case).

The warning has been removed in FPC trunk/2.7.1/development version.

If there are critical problems in FPC 2.6.2 code, we'll try and
backport a fix from FPC trunk to a 2.6.x maintenance release.

(and the fixes branch.  the 2.6.4 release cycle will probably start in
september)
