How to I add an entry (icon and description) to the windows tray while my VB App is running.  Of course it will have to be removed also when the app terminates.

Create a new project and add a picturebox.   Set the picture property of the picturebox to the icon you want to use in the tray.  This particular example makes an app that minimizes to the tray.  Double clicking the tray icon brings the app back.  Hitting the close button also makes the app go back to the tray.  Then (compiled) app can only be closed from the task manager.
