Play .wav one by one

Hi,
How can I play the wave files one by one?  Currently, I use sndPlaySound to play wave files:

procedure TForm1.Button1Click(Sender: TObject);
begin
     sndPlaySound(pchar(wavefile),SND_ASYNC);
     //wavefile is the filename obtained from
     //elsewhere of the program, changes continuously
end;

However, if the user click the button again while a wave is still being played, the playing wave will be stopped immediately, and the new wave will be played.
What I want is: to ignore (NOT put the play requests in a queue) the button click until the wave file is finished.

Thank you.

just use the tmediaplayer and OnClick of whatever
check

    case Mediaplayer1.mode of

    mpPlaying :
     begin
        Timer1.Enabled := True; // ignore ( do what you want)
     end;
    mpStopped :
     begin
        Mediaplayer1.play;
     end;
    end;

Hi, Below is some code that should help you get what you need. I used 3 wave files on my desktop, adjust the path/directory as neccessary to your own wav.files.
Hope this helps you.

Hello

  try this api with two parametrs :
  snd_sync or snd_nostop

  I didn't test it, cuz my sound card not working :(

  also try to use PlaySound api instead of sndplaysound, cuz it's the new version and it found for backward compatibility, and it's subset of PlaySound


Best regards
