Hi all I have doing it last nigh and i want to share it with you! I think you should use Invoke method to got some functions in API or MFC to play sound. You can use some prototype like this to get some functions. I mean playsound function to play a song with .wav using System; using System.Runtime.InteropServices; namespace ClassSound { /// /// Summary description for InvokeSound. /// public class InvokeSound { public InvokeSound() { } [DllImport(coredll EntryPoint=PlaySound CharSet=CharSet.Unicode CallingConvention=CallingConvention.WinapiSetLastError=false)] public static extern bool ExplicitSyntax_PlaySound( string szSound IntPtr hMod int flags ); //This method uses the default values for all the arguments of the DllImport attribute instead //of explicitly providing values for them like the ExplicitSyntax_PlaySound procedure above. [DllImport(coredll)] public static extern bool PlaySound (string szSound IntPtr hMod int flags); [DllImport(coredll)] public static extern IntPtr MCIWndCreate(IntPtr hwndParent IntPtr hInstance int dwStyle string szFile); [DllImport(coredll)] public static extern long MCIWndClose(IntPtr hwnd); [DllImport(coredll)] public static extern void MCIWndDestroy(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndEnd(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndHome(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndPause(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndPlay(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndResume(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndStop(IntPtr hwnd); [DllImport(coredll)] public static extern long MCIWndSetVolume(IntPtr hwnd int iVol); [DllImport(coredll)] public static extern void MCIWndSetRepeat(IntPtr hwnd bool f); [DllImport(coredll)] public static extern IntPtr GetSafeHwnd(); [DllImport(coredll)] public static extern IntPtr AfxGetInstanceHandle(); } } after that you can use these function as well as API in win32 good luck
