Disable warning/error beep when changing focus
<p>Whenever I change the focus from one textbox to another it plays an irritating warning/error beep.</p>

<p>Example:</p>

<pre><code>public void textBox1_KeyPress(object sender, KeyPressEventArgs e)  
{  
    if (e.KeyChar == (char)Keys.Return)  
        textBox2.Focus();  
}
</code></pre>

<p>whenever I press <strong>Enter</strong> it changes the focus to textBox2 and gives the warning beep.</p>

<p>Any help to disable this would be appreciated.
Thank you.</p>
