PlaySound question

[Harry J. Smith]

I added some sounds to my application, but the example in the msdn Library did not work.
It had:

[DllImport("coredll")]
public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );

The file coredll was not found. I changed it to [DllImport("WINMM")] and it now works.
What is the best way to handle this?

Hi Harry,

code.dll ( Please note that you forgot the . in your post ) is a dll from
the PocketPC platform. so the code you took maybe intended to run on a
PocketPC, if not you have to change it to the correct dll from the desktop.

Cheers,

Thanks Mike, your C# Tutorial is great.

The short answer to me question is use

[DllImport("winmm.dll")]
public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );

I also put in an exception handler to keep the application from crashing:

public class Sound
{
public static void Play( string strFileName )
{
try
{
Helpers.PlaySound( strFileName, IntPtr.Zero, Helpers.PlaySoundFlags.SND_FILENAME |
Helpers.PlaySoundFlags.SND_ASYNC );
}
catch
{
// DllImport("winmm.dll") file not found or no PlaySound entry point in the file
// so generate no sound
}
}
}
