C# How to remove 'ding' system sound when w,s,a,d buttons are pressed

Question

First of all i can not use

KeyEventArgs.SuppressKeyPress

Because i am using Key_Down event to listen to input from the user,essentially i am making a Pacman game and when the user presses W or S or A or D there is a 'ding' sound that windows makes.I want to disable it but i do not know how. My Key_Down method:

if (e.KeyCode == Keys.A) //A press moves left
        {
            k = 1;
            left = true;
            right = false;
            up = false;
            down = false;
        }
        else if(e.KeyCode == Keys.D) //D press moves right
        {
            k = 3;
            left = false;
            right = true;
            up = false;
            down = false;
        }
        else if(e.KeyCode == Keys.S)
        {
            k = 2;
            left = false;
            right = false;
            up = false;
            down = true;
        }
        else if(e.KeyCode == Keys.W)
        {
            k = 4;
            left = false;
            right = false;
            up = true;
            down = false;
        }

My form uses buttons that i disable when the user presses the 'Start' Button. i use:

Button.Disable = true; is it perhaps caused by the buttons still listening for user input or what? I also have some labels and a Listbox,do i need to disable them too?

The linked code also uses `e.SuppressKeyPress = true`. You should try that. — Jimi, Feb 28 '18 at 13:21

You'll have to make up your mind. You can use wasd to move a game object *or* you can use it for text input. Not both. — Hans Passant, Feb 28 '18 at 13:30

If your are using .NET framework then add this line of code just after your handling:

        e.SuppressKeyPress = true;
