Delphi Programming question

I would like to "Pack" my paradox-table at run-time. By packing I am refering to deleting empty records. In the Database Desktop you can do this when selecting "Restructure", but I want this to be automatic within my application.

I use Delphi Developer 2.0.

Thanks!

Try this
  uses  DBIProcs, DBITypes, DBIErrs;

  function PackTable(table:TTable; db:TDatabase):DBIResult;
  var
    crtd: CRTblDesc;
  begin
    Result := DBIERR_NA;
    with table do if Active then Active := False;
    with db do if not Connected then Connected := True;
    FillChar(crtd,SizeOf(CRTblDesc),0);
    StrPCopy(crtd.szTblName,table.TableName);
    crtd.bPack := True;
    Result := DbiDoRestructure(db.Handle,1,@crtd,nil,nil,nil,FALSE);
  end;

Example of use:

  procedure TForm1.Button1Click(Sender: TObject);
  begin
    if PackTable(Table1,DataBase1) = DBIERR_NONE then .....
    else MessageBeep(0);
  end;
