Hello,

I'm developing a handheld barcode scanning application and have a textbox that accepts the input.  All is well except I would like a simple "beep" after I detect the input.

Is there a simple API call, etc. that can do this?  I don't need anything fancy like playing a wav file, etc.  (Maybe for version 2).

VS 2005 - WM 5.0 - CF 2.0 - C#

Getting warmer... do you know how I can get the System.Media namespace into my CF 2.0 app?  It doesn't seem to have a reference.

It actually might be easier to play the wav file. :)

Actually you can do the following:
Microsoft.VisualBasic.Interaction.Beep()

You just need to add a reference to Microsoft.VisualBasic.dll in the project.

Or you can p/invoke:

    [DllImport("kernel32.dll")]
    public static extern bool Beep(int freq,int duration);

Thanks... what am I doing wrong in this test program?  Getting:

System.MissingMethodException was unhandled
  Message="Can't find PInvoke DLL 'kernel32.dll'."


using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace Beep
{
    public partial class Form1 : Form
    {

        [DllImport("kernel32.dll")]
        public static extern bool Beep(int freq,int duration);


        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Beep(1000,1000);
        }
    }
}

This was a more detailed solution and targeted for the CF:

Works in VS08 WM5 CF 2 C#
seems to be alot easier than all that other stuff(which didn't work for me anyway)
System.Media.SystemSounds.Beep.Play();
