I can enumerate the applications (handle,pid,path) with icons in the notification area, and I can control the position of the icons, but I can\'t get the tooltip.

You should take a look at the madKernal package of madshis component collection. It has some interfaces for working with trayicons. Beware, though:
With madKernel you can manage tray icons (see API "Shell_NotifyIcon") of any application. This kind of functionality is totally undocumented, but works well from win95 to winXP.
The ITrayIcon-interface has properties for hint, icon, position and more.
