        private const int SND_SYNC = 0x0000;
       private const int SND_ASYNC = 0x0001;
       private const int SND_NODEFAULT = 0x0002;
       private const int SND_MEMORY = 0x0004;// SND_LOOP
       private const int SND_LOOP = 0x0008;
       private const int SND_NOSTOP = 0x0010;
       private const int SND_PURGE = 0x40;
       private const int SND_APPLICATION = 0x80;
       private const int SND_NOWAIT = 0x00002000;
       private const int SND_ALIAS = 0x00010000;

       private const int SND_FILENAME = 0x00020000;



      <blockquote class="FQ"><div class="FQA">Quote:</div>PlaySound(Application.StartupPath + @"\wavs\patient_no.wav", 0, SND_SYNC );

               for (int i = 0; i < wav_arr.Length - 1; i++)
               {
                 PlaySound(Application.StartupPath + @"\wavs\" + wav_arr[i] + ".wav", 0, SND_SYNC);
              }
                PlaySound(Application.StartupPath + @"\wavs\go_to_lab.wav", 0, SND_SYNC | SND_NODEFAULT | SND_PURGE);

                //PlaySound(null, 0, SND_PURGE);
</blockquote>  


  </blockquote>

当我使用异步时
...程序没​​有停止>>像计时器一样，但它只返回最后一个声音

如果我使用同步程序停止直到声音完成



我该如何解决它



这是一个问题和标志

但不知道哪个会起作用完美不要挂我的应用程序



thanx很多

when i use async... the program doesn't stop >>like timers ,, but it returns only the last sound
and if i use sync the program stops till sound finished

how can i fix it

it's a problem wth flags
but dont know which will work just perfect an dont hang my app

thanx alot

推荐答案

我假设这是C＃......



跳过非托管代码，只需使用 System.Media.SoundPlayer [ ^ ]它将在单独的线程中播放声音，而不会锁定您的应用程序。

I'm assuming that this is C#...

Skip the unmanaged code, just use System.Media.SoundPlayer[^] which will play the sound in a separate thread without "locking up" your application.
