[Dev-C++] How to hide and show a shell notify icon

[Ahmed H. <ahm...@gm...>]

Hello, I am preparing a system tray icon class for Windows XP.
I got stuck at Hide() and Show() member functions. I have no idea what code
should I write for them. Any help will be appreciated.
I tested the other member functions, they are all running with no error.
