Force a TEdit to accept only numeric input


I've seen the tip to make a TEdit accept only numbers but there is an easier way to do it. This is the function I use in my applications:

procedure SetEditNumeric(Handle: THandle);
  SetWindowLong(Handle, GWL_STYLE,
    GetWindowLong(Handle, GWL_STYLE) or ES_NUMBER);
