C# NotifyIcon stays in tray after the Balloon Tip has been closed

Question

after the Ballon Tip of my NotifyIcon has been close the icon still stays in tray. It vanishes only when I hover it with my mouse cursor.

I have a class Notification.cs which has one component - NotifyIcon.

I call it from my Console Application as I only want to show the notification when certain conditions are fulfilled.

Some code:

how I call the notification from within my program:

Notification not = new Notification("Error occured, do this or that", "Some error", System.Windows.Forms.ToolTipIcon.Error);
not.getIcon().ShowBalloonTip(1000);

the notification class:

public Notification(string baloonTipText, string baloonTipTitle, System.Windows.Forms.ToolTipIcon icon) : this()
{
    this.icon.Visible = true;
    this.icon.BalloonTipText = baloonTipText;
    this.icon.BalloonTipTitle = baloonTipTitle;
    this.icon.BalloonTipIcon = icon;
}

public System.Windows.Forms.NotifyIcon getIcon()
{
    return this.icon;
}

private void icon_BalloonTipClosed(object sender, EventArgs e)
{
    this.icon.Visible = false;
    this.icon.Dispose();            
}

Any ideas?

I asked [the same question](http://stackoverflow.com/questions/10980029/notify-icon-stays-in-system-tray-on-application-close) a while ago and got no answers but a few helpful comments — JMK, Oct 19 '12 at 11:24
@JMK I'm not so sure this is the same question. The way I read this question, the program is still running. — , Oct 19 '12 at 11:35
@JMK the link was helpful, I can now get rid of the notifications ([http://safari-tech.serveblog.net/?p=101]) but the problem is that call to the method `RefreshTaskbarNotificationArea()` in `icon_BalloonTipClosed` method doesn't work for me. I have to call it externally, which is not a good option @hvd yes, the main program is still running - I instantiate the Notification class, get it's icon and show the balloon tip only to tell the user sth went wrong @BigM I don't really understand your question. It's a class I created in VS using the Component Class Template — wojtuch, Oct 19 '12 at 12:41

Because you're running in a console application, your icon_BalloonTipClosed handler will not be invoked when the balloon tip is closed (no message pump). You will need to call Dispose manually either as your application exits or set a timer (System.Threading.Timer, System.Windows.Forms.Timer will not work) with a timeout longer than the balloon tip's timeout. e.g.:

timer = new Timer(state => not.getIcon().Dispose(), null, 1200, Timeout.Infinite);

will try it after the weekend and will then tell if it worked. thanks! — wojtuch, Oct 19 '12 at 16:25
