Tray icon etc. not showing when started by Service

Hi
I have an control app which starts up with a small info message then sits
down as a tray icon while it does its work. When started manually (e.g.from a
shortcut) this always works fine. However the app is designed to start
automatically (via a windows service) whoever is logged on. Sometimes, when
started by the service, neither the info message nor the tray icon appear.
The app is working fine in the background, but without the tray icon users
can't make adjustments to the app.
Why should the app behave differently in this way?

Are you handling the proper user logon events and registering your icon at that
time, or just during your startup (when no user is logged on)?

I'm not handling lgone events (is there an evenmt handler for this - what's
it called?) but after doing some tests this seems not to be the problem. In
fact every time the system starts from a reboot (even if nobody logs on for
several minutes) the icon appears.
It's most likely not to appear when the app is stopped then restarted by
stopping and then restarting the control service, with the same user logged
on throughout.
Although this is not a likely sequence to manually go through, it is in
effect what happens if the main app freezes and the control app then does its
job of restarting the main app.

Hello all, I wrote a shell program a few years ago in VB6 that needs to be modified. The problem I have is this: The SysAdmin uses this shell in place of Explorer, so there is no taskbar. When his users run PC Anywhere from the shell, and minimize it, it minimizes to the system tray. With no task bar, there is no system tray, so there is no way to restore the PC Anywhere window. The shell starts PC Anywhere using ShellExecute. I...

Hi, I have a form with a tray icon. However, when I minimize the form, it stays visible - not in the task bar (I have showintaskbar property set to false), but in a form of a rectangle sitting above the task bar. Can't figure out why that happens - it looks very ugly... Any ideas ? Zeljko

Hi, I'm having a hard time getting my service to show a sys tray icon. I've tried to create a separate Windows application where I simply add a notification icon to the form.

Hello-- I have made a C# executable that monitors the server it is placed on. This works great so far. Since I don't have physical access to this machine, I have my executable launched by task manager and it runs in the background. Its owner is SYSTEM, so that when I log out of terminal services, the application is still running.

I am using VS2005 (vb) and I have a program that starts when Windows boots up. Occasionally the icon that should appear in the system tray does not show up. The program is still running in memory but the tray icon is not there. If I start the program after Windows has booted up the icon shows every time. I am assuming that the reason is due to the icon being created before the system tray is loaded/running. I have used a timer with...

The conventional approach is easy enough; drop a NotifyIcon onto a Form. When the form is loaded - bingo - the icon appears in the System Tray. I can't use this approach though. I'm writing a service. But I'd like my service to install an icon on the System Tray so that the user can start / stop / and otherwise control the service interactively, and without having to go to the Services applet. How do I do this? Thanks for your advice.
