(ne jen na prvni)

Help please ...

navodu je na netu hafo. staci si vybrat ;)

Kód:

mciSendString('open cdaudio!X: alias driveX', nil, 0, 0);
mciSendString('set driveX door open wait', nil, 0, 0);

// a todle pro zavreni
mciSendString('set driveX door closed wait', nil, 0, 0);

function IsDriveCD(Drive : char) : longbool;
var
  DrivePath : string;
begin
  DrivePath := Drive + ':\';
  result := LongBool(GetDriveType(PChar(DrivePath)) and RIVE_CDROM);
end;

function EjectCD(Drive : char) : bool;
var
  mp : TMediaPlayer;
begin
  result := false;
  Application.ProcessMessages;
  if not IsDriveCD(Drive) then exit;
  mp := TMediaPlayer.Create(nil);
  mp.Visible := false;
  mp.Parent := Application.MainForm;
  mp.Shareable := true;
  mp.DeviceType := dtCDAudio;
  mp.FileName := Drive + ':';
  mp.Open;
  Application.ProcessMessages;
  mp.Eject;
  Application.ProcessMessages;
  mp.Close;
  Application.ProcessMessages;
  mp.free;
  result := true;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
