How to get music to play in Delphi 7?

I need to get music to play in the backg开发者_如何学编程round in the start of the program in the OnFormActivate event for my program. I have the song I want to use but I dont know what command Delphi needs to use in order to start playing that song.

Thanks for you help guys :)

Use the TMediaPlayer component, it's on the System tab of the component palette.

procedure TForm1.FormActivate(Sender: TObject);
begin
  MediaPlayer1.FileName := '<fill in>.mp3';
  MediaPlayer1.Open;
  MediaPlayer1.Play;
end;

Set the Visible property to False.

Edit in response to OP's comment:

To repeat the song, you can use the TTimer component, also found on the System tab. To repeat the song with a one second delay:

procedure TForm1.FormActivate(Sender: TObject);
begin
  MediaPlayer1.FileName := '<fill in>.mp3';
  MediaPlayer1.Open;
  MediaPlayer1.TimeFormat := tfMilliseconds;
  Timer1.Interval := MediaPlayer1.Length + 1000;
  MediaPlayer1.Play;
  Timer1.Enabled := True;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  MediaPlayer1.Play;
end;

Set the timer's Enabled property to False.

You can use TMediaPlayerComponent.
Here you can find a tutorial on how to use it.
