why afta i run the file there an errors in line "PlaySound(strFileName, IntPtr.Zero, SoundFlags.SND_FILENAME Or SoundFlags.SND_ASYNC) End Sub"

An unhandled exception of type 'System.MissingMethodException' occurred in LearnJapaneseTutorialSystem.exe
any mistakes dat i did?

okay..thank you for the program.i donwload it again..so,as u done it in windows application.isit the coding for windows app n smartdevice app is the same?because when i try it in smartdevice application,there an error in line afta i run
PlaySound(strFileName, IntPtr.Zero, SoundFlags.SND_FILENAME Or SoundFlags.SND_ASYNC)

the error sed "An unhandled exception of type 'System.MissingMethodException' occurred in SmartDeviceApplication2.exe"

im doing myproject in smartdevice application.isit i stil can using the same coding?because it seems still having an error on PlaySound(strFileName, IntPtr.Zero, SoundFlags.SND_FILENAME Or SoundFlags.SND_ASYNC)
which it sed "An unhandled exception of type 'System.MissingMethodException' occurred in SmartDeviceApplication2.exe"
