run a sound wave

انا مجربتش ال Code بس اول حاجة شوفتها

//[DllImport("WinMM.dll")]

دا Comment ليه؟؟؟؟؟

شيل ال //

if I remove it I have an error

لان تعريف الfunction خطأ

هذا هو التعريف الصحيح

  [DllImport("winmm.dll", EntryPoint="PlaySound",CharSet=CharSet.Auto)]
  private static extern int PlaySound(String pszSound, int hmod, int falgs);

thx

but the code still not working why??

what is the error?

when I press the button to run the sound, I cant hear anything WHY??

This is a working code

using System;
using System.Runtime.InteropServices;
using System.IO;

namespace PlaySound
{	
	/// <summary>
	/// Helper for playing wav files and System Events stored under HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default

 	 SND_PURGE           = 0x0040,  /* purge non-static events for task */
 	 SND_APPLICATION     = 0x0080  /* look for application specific association */
  }
  /// <summary>
  /// Plays specified wav file.
  /// </summary>
  /// <param name="pszSound">Path points to the wave file.</param>
  /// <returns></returns>
  public static void PlaySound(String pszSound)
  {
 	 if(File.Exists(pszSound))
 	 {
    PlaySound(pszSound,0,(int) (SND.SND_ASYNC | SND.SND_FILENAME | SND.SND_NOWAIT));
 	 }

  }

  public static void PlaySoundEvent(String pszSound)
  {	
 	 PlaySound(pszSound,0,(int) (SND.SND_ASYNC | SND.SND_ALIAS | SND.SND_NOWAIT));
  }
	}

}

and this is another working code
