Extend your legal chess move identification program as follows: • Allow the user to add an arbitrary number of pieces to the board (either red/black or white) • Allow the user to select a given piece and then that piece must work out its set of valid moves from its current position • A piece cannot move over a piece which is the same colour as it is • A piece may move over (and replace) a piece which is of the opposite colour. • Create a Visualiser Abstract Base class which implements a show() pure virtual function • Create a TextVisualizer derived class which overrides show to display the chess board (with legal moves for the selected piece) to the standard output stream • Create a GraphicalVisualizer derived class which overrides show to display the chess board (with legal moves for the selected piece) as an image.
I have a CListCtrl control with single column (item only , no subitems yet) containing text “COMX” - list of all COM ports in the system. I can select the first and last COM port with mouse pointing to letter "C" only. The mouse cursor changes when the mouse is over “OMX” part of the entry. All of the other ports can be selected with mouse anywhere over the “COMX” text. Is this normal or user error?
