    System tray icon

    Hi,

    I have an application that is controlled by a service. when the service
    starts, an icon is supposed to be placed in the system tray and this icon is
    then used to display a balloon intermittently. the problem is that when the
    icon is placed in the balloon and for some time after this, it is visible in
    the system tray, but after some time if i try to hover the mouse over the
    icon, it then disappears, although i still get a message that it is visible.

    this happens whether "hide inactive icons" on the taskbar properties is
    checked or not.

    please let me know what i may be doing wrong...at my wits end. i am working
    in VS 2003

    Thanks for any help.

      Is the icon added by the service itself or a separate application that
      communicates with the service?

          Thanks for replying.

          The icon is added by the service when it starts running.

          I have now transferred my program to VS 2005 and still getting the same
          problem.

          The notify icon is on a component and not on a form, could this be the
          problem??

              The problem is that a service mustn't show an icon because a service does
              not have a user interface.

                  Hi,
                  thanks for the response. do you have any references/websites as to where i
                  can read more about this?

                  So how do all the other icons that are displayed in the system tray stay
                  there permanently?

                          There's typically a separate application configured to run at startup
                          (or rather when the user logs in). It communicates with the service
                          through some IPC mechanism.
