When an owner window of the menu item decides how the menu item should look, then the menu item is known as Owner Drawn Menu. The default windows provided menu has a standard look and feel. We cannot add Red and blue-colored boxes as a menu item through the resource editor. In this Example, we will see how can we display only color boxes as a menu item under the color menu.

We know that keyboard and mouse are basic hardware interface supported by almost all the Computer Operating System. When the user hits the keyboard key, the device driver for the keyboard deals with it by making use of the interrupts.

Moreover, knowing how to carry out this in run-time is useful as the Application can behave based on the INI file or configuration file settings.
