how To Play sound

O

org

I'm trying to play a .wav file in .NET CF 2.0
So I included the File I wished in Properties.Resources.myWaveFile .
I added the following Sound-class. This class is from MSDN, but I added an
additional Constructor for byte[]:

public Sound(byte[] data)

{

m_soundBytes = data;

}



and in my main-program i did an:
Sound sound = new Sound(Properties.Resources.miss);

sound.Play();

But this didn't do anything. Wenn I do an new Sound("myFile.wav") with
myFile.wav on the pocketPC,I can hear the sound. So what is wrong?!?Best

m_fileName;private enum Flags {SND_SYNC = 0x0000, /* play synchronously

You can get the stream from the resource:

Stream soundStream = Assembly.GetManifestResourceStream(yourResourceName);

Sound sound = new Sound(soundStream );

Hi,
thanks but this gives me an Error: An object reference is required for the
nonstatic field, method, or property
'System.Reflection.Assembly.GetManifestResourceStream(string)'

Check that 'string' is the correct name.

You can check with (off the top of my head):

string[] values = System.Reflection.Assembly.GetManifestResourceNames();

The names will start with the Assembly Name (I think) and then has folder
structure also.

You need the Assembly instance for your exe -
Assembly.GetExecutingAssembly().GetManifestResourceStream(youResourceName);
