Using CoolTrayIcon to minimize form to tray
Sometimes we need to run a program in the background.

To save some space on the taskbar, which the running application will
occupy, we can display it in a tray.

An easy way to do this is using a free component CoolTrayIcon by Troels
Jakobsen.  It can be downloaded at

So, to display a program in a tray, set ShowMainForm property of the
component to false on it's OnStartup event.

The component has a lot of other features, such as animation
and pop-up menu, etc.  They are described in details in its
help file.
