i imagine you would need to find the windows handle of the tray icon

use winsight that comes with Delphi
when you move the mouse over the tray icon you'll get messages for that window handle.

the next thing would be to find out the unique number for that icon, it's in the NOTIFYICONDATA

then you can send a msg NIM_DELETE for that icon
the application may of course update the icon after you deleted it

Take a look at the SystemTray source code I provided in the following paq.

http://www.experts-exchange.com/Programming/Languages/Pascal/Delphi/Q_21976678.html

this will let you enumerate all the tray icons, and interact with them as well. In this case, you would just set the .Visible property for each to false. Let me know if you need assistance using the code.
