Enter button creates sound when opening messagebox

Tried several ways, can't figure out how to disable the 'ding' sound. I know this is basic, but I really can't figure it out. Any advice is greatly appreciated





This is my button press event.

Code:

---

private void txtResult_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
               

                if (!String.IsNullOrEmpty(txtResult.Text))
                {
                    btnCheckAnswer.PerformClick();
                    e.SuppressKeyPress = true;
                    e.Handled = true;
                }
             
            }


        }



This is one of the btnCheckAnswer.PerformClick() actions
            }
                    }

                }

                else
                {
                    numRight++;
                    MessageBox.Show("Smarty Pants, You're Right!!");
                    NextQuestion();
                    IncreaseScore();
                }
                return;

            }

        }

If we go by the naming convention, txtResult_KeyDown() isn't a button click event, it's a text change event for a textbox. If you need to handle a button click, then setup an OnClick handler.

Windows will ding when you are in the middle of doing something with the keyboard, but haven't finished processing it. If you try to do something in the middle, it will ding.

At any rate, what does btnCheckAnswer.PerformClick(); do? Are you trying to simulate a button click?

IIRC from way back when I still did GUI coding, you need to clear the KeyCode of the KeyEventArgs. Set it to zero. But you need to use KeyPress (if that is what the event is called using C#) instead of KeyDown.
