Hiding disabled application functionality

procedure TXXXXXXXXXForm.btnHelpClick(Sender: TObject);
begin
  //This button has been made invisible as there is no help yet available for this form
  // when help is written/available make the button visible again.

  //It is better to hide a feature that doesn't yet exists than post a message
  // saying that it doesn't yet exist when the user tries to use it.
end;
