Here's how I solved that little problem.

Add this simple class to your project. It's part of my personal library now but you can add the class directly in your project

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace MyCSharpLibrary
{
    public class Volume
    {
        [DllImport("winmm.dll")]
        public static extern int waveOutGetVolume(IntPtr h, out uint dwVolume);

        [DllImport("winmm.dll")]
        public static extern int waveOutSetVolume(IntPtr h, uint dwVolume);

        private static uint _savedVolumeLevel;
        private static Boolean VolumeLevelSaved = false;

        // ----------------------------------------------------------------------------
        public static void On()
        {
            if (VolumeLevelSaved)
            {
                waveOutSetVolume(IntPtr.Zero, _savedVolumeLevel);
            }
        }

        // ----------------------------------------------------------------------------
        public static void Off()
        {
            waveOutGetVolume(IntPtr.Zero, out _savedVolumeLevel);
            VolumeLevelSaved = true;

            waveOutSetVolume(IntPtr.Zero, 0);
        }
    }
}

Now call Volume.Off() before calling MessageBox and Volume.On() after

Volume.Off();
MessageBox.Show("\n Information \n", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
Volume.On();

I prefer that approach because I don't have to make modifications to Windows and I can select any icons I want for my MessageBoxes.

Thank you, bye

This is going to sound weird until you have tried it. Open your command prompt, type:

net stop beep

I did a quick google and found 4 other ways:

1. local machine: sc stop beep && sc config beep start= disabled
2. remote machine: sc \remoteMachine stop beep && sc \remoteMachine config beep start= disabled
3. requires reboot: Device Manager -> View -> Show Hidden Devices -> Non Plug and Play -> Beep -> Disable
4. use TweakUI: General > Settings -> Uncheck the Beep on Errors

(from here)

Try using the VisualBasic MsgBox class instead of the MessageBox. I cannot explain why, but on my computer, the VisualBasic one doesn't beep.

http://msdn.microsoft.com/en-us/library/sfw6660x%28VS.85%29.aspx

So instead of:

MessageBox.Show("text")

do:

MsgBox("text")

You'll have to import the MsgBox function from Microsoft.VisualBasic, instead of importing MessageBox from System.Windows.Forms. But that shouldn't be a problem; it's part of the .NET api.

EDIT: Ah ok, now I can explain it. The lack of sound is because the VB version of the MessageBox is undecorated (i.e. it's not informational, a question, etc.) by default. I assume there's no real need to use the VB MsgBox class after all--probably if you make the regular old MessageBox undecorated, it won't make any sound either. :)

From the searching I've done it looks like the beep is hardwired into the Win32 message box function:

• Bytes
• VB Forums

So you need to either write your own method or stop the beep in the hardware. The former will work for everyone, the latter just for you.

Answer 5

You should leave it to the end user to decide what sounds he wants. He can configure/disable sounds for system events such as a messagebox in Control Panel / Sounds and Audio Devices / Sounds / Program Events.

Stopping the beep service required administrative privileges, and isn't something you'd normally do just for one application.

If you do go for a custom dialog to replace the MessageBox, please remember to implement CTL-C (copy messagebox contents to clipboard).

Answer 6

Despite this question being old I had the same problem but was able to fix it in a very simple way.

MessageBox.Show("Your text here", "Information", MessageBoxButtons.OK, MessageBoxIcon.None);

By setting the MessageBoxIcon to None the system produces no sound. However, there will be no icon on the box. Something like this.
