我重TMemoryStream讀取音樂資料卻無法撥放
有用MediaPlayerMemoryFile來讀取TMemoryStream但還是無法撥放

http://delphi.ktop.com.tw/board.php?cid=168&fid=921&tid=90327

我打的程式碼如下，請各位大大幫我解謎


[code delphi]
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, cmpMediaPlayerMemoryFile, MPlayer;
type
TForm1 = class(TForm)
MediaPlayer1: TMediaPlayer;
MediaPlayerMemoryFile1: TMediaPlayerMemoryFile;
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
var
t: TMemoryStream;
begin
t:=TMemoryStream.Create;
t.LoadFromFile('1234.wav');
MediaPlayerMemoryFile1.MemoryStream.LoadFromStream(t);
t.Free ;
MediaPlayerMemoryFile1.FileName := 'test.xxx';
MediaPlayer1.FileName:= MediaPlayerMemoryFile1.FileName ' ' ;
MediaPlayer1.DeviceType := dtWaveAudio ;
MediaPlayer1.Open;
MediaPlayer1.Play;
end;
end.[/code]

 沒人幫我解決 我來自問自答好了(絞盡腦汁終於改成功了.....)

把 uses MPlay 裡面程式碼 (記得另存為新的副程式在去uses他)
[code delphi]
if FDeviceType <> dtAutoSelect then
FFlags := FFlags or mci_Open_Type;
if FDeviceType <> dtAutoSelect then
FFlags := FFlags or mci_Open_Type
else
FFlags := FFlags or MCI_OPEN_ELEMENT;[/code]
改成這樣就可以撥放了
[code delphi]
if FDeviceType <> dtAutoSelect then
FFlags := FFlags or mci_Open_Type;
if FElementName <> '' then
FFlags := FFlags or MCI_OPEN_ELEMENT;[/code]
