Hast du die StringList auch erstellt ?

Delphi-Quellcode:

var
   PlayList: TStringlist;

procedure ... FormCreate...
begin
  PlayList := TStringlist.Create;
end;

procedure ...AddToPlayList(s:string);
begin
   playList.Add(s);
   PlayListBox.Items.Add(extractfilename(s));
end;

procedure ... FormDestroy...
begin
  PlayList.Free;
end;
