supress beep

Question

 private static void Txb_KeyDown(object sender, KeyEventArgs e)
        {
            var txb = (TextBox)sender;
            var intfc = (ICustomTextBox)sender;
            if (e.KeyCode == Keys.Escape)
            {
                txb.Text = "";
                return;
            }
            if (!intfc.Last)
            {
                if (e.KeyCode == Keys.Enter) 
                {

                   Control ctl = txb;
                    while (ctl.Parent != null)
                    {
                        var next = ctl.Parent.GetNextControl(ctl, true);
                        if (next != null)
                        {
                            next.Focus();
                            e.SuppressKeyPress = true;
                            e.Handled = true;
                            return;
                        }
                        ctl = ctl.Parent;
                    }
                }                
            }
          
            if (e.KeyData == (Keys.Control | Keys.V) ||
                e.KeyData == (Keys.V | Keys.Alt | Keys.Control))
            {
                txb.SelectedText = Clipboard.GetText();
                e.SuppressKeyPress = true;
                e.Handled = true;
                return;
            }

        }

in the Txb_KeyDown event ,as e.SuppressKeyPress = true; is preventing the system to generate the beep sound when the user presses enter key , i am trying that beep sound should not happen for any of the keys or keys combination . i had tried putting

e.SuppressKeyPress = true;

in this event but instead , it blocks the user input .

Hi @Pankaj tripathi , Welcome to Microsoft Q&A,

If you want to disable the beep when the bool variable last is set to true and the user presses the enter key.

Your problem may be one of judgment. Try using

  // Check if the user pressed Enter and last is true
     if (e.KeyCode == Keys.Enter && intfc.Last)
     {
         e.SuppressKeyPress = true;
         e.Handled = true;
         return;
     }

Best Regards,

Jiale
