How to remove Windows BIP sound in c#?

Question

I hope you guys are okay. I developed a C# application in Visual Studio, but when pressing the 'TAB' key to change textBox1 to textBox2, it makes the sound of Windows (which is actually the ENTER key I changed in the script). How do you get that sound out? I tried the code below but it didn’t work...

private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Tab)
        {
            e.SuppressKeyPress = true;
        }
    }

Thank you!

You have to prevent the event KeyPressed is generated, which is such a beep. For this, you have to indicate that the event was successfully completed:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Tab)
    {
        textBox2.Select();
        textBox2.Focus();
        e.Handled = e.SuppressKeyPress = true;
    }
}
