Q&A

Q1:	Is it possible to capture keystrokes at the form level, rather than capturing them in control events?
A1:	Yes. For the form's keyboard-related events to fire when a control has the focus, however, you must set the form's KeyPreview property to true. The control's keyboard events will still fire, unless you set `KeyAscii = 0` in the form's KeyPress event and `KeyCode = 0` in the form's KeyDown event.
Q2:	You don't seem to always specify a button in your MessageBox.Show() statements throughout this book. Why?
A2:	If you don't explicitly designate a button or buttons, C# displays the OK button. Therefore, if all you want is an OK button, you do not need to pass a value to the buttons argument.
