Compacting an MS Access database from Delphi...

Hi!
I need to be able to compact an MS Access database from delphi.
Is there anybody out there who knows how i can do so??? If it is possible, I would like to be able to do this without having MS Access installed on the computer I am running the application.

Thanx!

Try with this function  using the ADO technology

Function CompactAndRepair(sOldMDB : String; sNewMDB : String) : Boolean;
const
       sProvider = 'Provider=Microsoft.Jet.OLEDB.4.0;';
var
       oJetEng   : JetEngine;
begin
       sOldMDB := sProvider + 'Data Source=' + sOldMDB;
       sNewMDB := sProvider + 'Data Source=' + sNewMDB;

       try
          oJetEng := CoJetEngine.Create;
          oJetEng.CompactDatabase(sOldMDB, sNewMDB);
          oJetEng := Nil;
          Result  := True;
       except
          oJetEng := Nil;
          Result  := False;
       end;
end;


Example :

if CompactAndRepair('e:\Old.mdb', 'e:\New.mdb') then
 ShowMessage('Successfully')
else
 ShowMessage('Error?');

if you would like to use DAO for old database like Access
97

uses ComObj;
procedure TForm1.Button1Click(Sender: TObject);
var
dao: OLEVariant;
begin
dao := CreateOleObject('DAO.DBEngine.35');
dao.CompactDatabase('C:\My Documents\DB1.mdb',
'C:\My Documents\CompactedDB1.mdb');
end;


Best Regards.
