Stop the 'Ding' when pressing Enter

Question

I have a very simple Windows Forms Application. And, in Windows (or, atleast Windows Forms Applications), when you press Enter while inside a Single-line TextBox Control, you hear a Ding. It's an unpleasent sound, that indicated you cannot enter a newline, because it is a single-line TextBox.

This is all fine. However, in my Form, I have 1 TextBox, and a Search Button. And I am allowing the user to Perform a search by pressing Enter after they've finished typing, so they don't have to use the mouse to click the Search Button.

But this Ding sound occurs. It's very annoying.

How can we make it so just that sound doesn't play at all in my Form?

@David H - Here's how I'm detecting the enter pressing:

private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        // Perform search now.
    }
}

It works for me:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{

    //Se apertou o enter
    if (e.KeyCode == Keys.Enter)
    {
        //enter key is down

        this.doSomething();

        e.Handled = true;
        e.SuppressKeyPress = true;

     }

 }

The SuppressKeyPress is the really trick. I hope that help you.
