Stop the 'Ding' When Pressing Enter

Stop the 'Ding' when pressing Enter

Check out the Form.AcceptButton property. You can use it to specify a default button for a form, in this case for pressing enter.

From the docs:

This property enables you to designate
a default action to occur when the
user presses the ENTER key in your
application. The button assigned to
this property must be an
IButtonControl that is on the current
form or located within a container on
the current form.

There is also a CancelButton property for when the user presses escape.

How can to stop the ding sound while pressing enter

Try setting e.Handled and e.SuppressKeyPress to True.

Private Sub TextBox2_KeyDown(sender As Object, e As KeyEventArgs) Handles TextBox2.KeyDown
    If e.KeyCode = Keys.Enter Then
        ' Your code...

        e.Handled = True
        e.SuppressKeyPress = True
    End If
End Sub

This should suppress the "ding".

Avoid Windows 'Ding' when Enter is pressed in TextBox with OnKeyUp

I imagine this is caused by a combination of:

MultiLine = false
No default button on the form

because single-line textboxes forward the enter key to the default button. The ding is generated when a default button can't be found.

Disable beep of enter and escape key c#

You have to prevent the KeyPressed event from being generated, that's the one that beeps. That requires setting the SuppressKeyPress property to true. Make that look similar to:

        if ((e.KeyCode == Keys.Enter) || (e.KeyCode == Keys.Tab))
        {
            Parent.SelectNextControl(textBox_Zakljucak, true, true, true, true);
            e.Handled = e.SuppressKeyPress = true;
        }

How do I stop a NumericUpDown from playing 'Ding' sound on EnterKeyPress

Use KeyDown() and SuppressKeyPress, but click the button in KeyUp():

    private void myNumericUpDown_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            e.Handled = e.SuppressKeyPress = true;
        }
    }

    private void myNumericUpDown_KeyUp(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            e.Handled = e.SuppressKeyPress = true;
            myButton.PerformClick();
        }
    }

*If you set the Forms AcceptButton Property to "myButton", then NO code is needed at all!
