Handle a keyboard message
Handle the xref:System.Windows.Forms.Control.KeyPress or xref:System.Windows.Forms.Control.KeyDown event of the active form and set the xref:System.Windows.Forms.Form.KeyPreview%2A property of the form to true. This property causes the keyboard to be received by the form before they reach any controls on the form. The following code example handles the xref:System.Windows.Forms.Control.KeyPress event by detecting all of the number keys and consuming 1, 4, and 7.
