Tray icon will not go away!

[george d lake]

Hi,
I have an app that runs in the system tray. When I exit the app (from a
button on a form) the app ends but the icon stays in the tray.
Any ideas?

here is the code I use to end the app

Me.Close()

Me.Hide()

m_trayIcon.Icon = Nothing

End

Set the Visable property of the NotifyIcon to false when your application is
closing.. Setting it to Nothing doesn't just make it go away..

Set the icon's 'Visible' property to 'False' before closing the form.

End

Why do you use 'End' here?!

Ok, I changed it to:

m_trayIcon.Visible = False
End

and iut still stays there. I have to mouseover it in order for it to go
away.

Change the order of you statements:
m_trayIcon.Visible = False
m_trayIcon = Nothing
Me.Hide()
Me.Close()

It's not a good idea to put statements after Me.Close(). If you do it that
way, you have to wait for GC to clean up after you, because m_trayIcon has
gone out of scope

Its part of a function that ends the app when a button is clicked. I do not
want to use the "X" from the form. Is there a better way of doing this?

There are *only* better ways of doing this.

Pass a reference to the form instance and call its 'Close' method.

George,
In addition to the others comments.

If your app a Form that happens to have a system tray icon. Or a System Tray
icon that happens to have a form?

In my app, which happens to be a System Tray icon that happens to have a
Form, I had to explicitly call Dispose on the Component where the NotifyIcon
was located, which indirectly caused Dispose to be called on the NotifyIcon.

Note the NotifyIcon was located in a class derived from Component. This
component was my startup object. It had a Shared Sub Main that created a new
instance of the component, then called Application.Run with no parameters.

Elsewhere in my program I would create an instance of a form and call
ShowDialog to show it, based on a Menu click event, the component owned the
Menu & NotifyIcon...

Hope this helps
Jay
