Application that displays an icon in the system tray and not in the taskbar?

How can i make an application that displays an icon in the system tray and not in the taskbar?
And how can i make it without any icon? I mean, like winamp.

Use Shell_NotifyIcon() API,

This is a sample code which displays an icon with a context menu in the systemtray. Use can the code by changing the menu identifier,icon identifier etc..
