Creating beep on pocket pc

Hello,
I am using win mobil 2003 se and developing web service applications on it.
Once the application connects to the gerver and get an delivery-order from the server the driver who is using the pda should get an sound alert.
I was trying to get some code, it uses the win dll import.
It is working on the desktop but not on the pocket pc.
I attach the code bellow.
Can anyone give me an idea why it is not working.
Do we have the same dll in the pda also(kernel32.dll).
I call this class from my main form.

using System;
using System.Runtime.InteropServices;
namespace EKS_comsy
{
public class BeepProcess
{
[DllImport("kernel32.dll")]
public static extern bool Beep(int frequency, int duration);
public BeepProcess()
{
Random random = new Random();
for (int i = 0; i < 10; i++)
{
Beep(random.Next(10000), 5);
}
}
}
}

thanks in advance.

Hi SweetsGreen,
Thenks for the reply.
I tried the way how you wrote.
My main test form i have a button and i say,

private void btnPlaySound_Click(object sender, System.EventArgs e)
{
BeepTest.Class1 newSound = new Class1();
newSound.play();
}

In my playsound class

using System;
using System.Runtime.InteropServices;
namespace BeepTest
{
public Class1
{
[DLLImport("coredll.dll")];
public static extern int MessageBeep (int frequency, int duration);
public void play()
{
Random random = new Random();
for (int i = 0; i < 10; i++)
{
MessageBeep(random.Next(10000), 5);
}
}
}
}

This code is working fine on the emulator but i do not hear any sound on the pocket pc.
I do not get any error too.
just i do not hear the sound. My sound setting is maximum.
I could not figur it out.

hlep me please.

thanks.
