How to System Tray Refresh?

[goodmorningsky]

I'm using NotifyIcon for my application to be shown in system tray.

However when it starts the app's tray comes out 1 ~ 3 tray.

More than 1 tray comes out on system tray --> it's problem.

But, When I mouse over on system tray only one tray of my app remains.

And when I terminats the app, the tray doesn't disappear until I put mouse on the system tray.

I think it's refresh problem. Why this happens with .NET NotifyIcon?

All other applications on my comp doesn't give this problem.

Is there a way fix this problem?

 

PS: I'm using Win2000.

when closing your application down , set the NotifyIcon's Icon to Nothing. eg:

'/// in your closing sub...
With NotifyIcon1
   .Icon = Nothing
   .Dispose()
End With

you can also set the Visible property to False if needed.

How are you terminating your application? If your app shuts down cleanly then the icon should be removed.

Also when you say 1 - 3 icons appear on startup are some of these left over from previous runs of the app?

Thank you for reply.

I'm adding my solution..

mnuExit is menu item in ContextMenu in NotifyIcon.

 

One tip I found is:

You should call Application.Exit() before

this.notifyIcon.Icon = null;

this.notifyIcon.Dispose();

Otherwise your application process will not be terminated!!

private void mnuExit_Click(object sender, System.EventArgs e)
	{
		if(MessageBox.Show(null, "Do you want to close all service and exit?", "Confirmation", 
			MessageBoxButtons.YesNo) == DialogResult.Yes)
		{
			this.StartStopAllServices(false);

			Application.Exit();
			this.notifyIcon.Visible=false;
			this.notifyIcon.Icon = null;
			this.notifyIcon.Dispose();
		}
	}

I always thought this was Windows 2000....

I'm not that experienced, but I don't understand why your system tray icon doesn't disappear when your form closes.

 

This code:

Application.Exit();
this.notifyIcon.Visible=false;
this.notifyIcon.Icon = null;
this.notifyIcon.Dispose();

doesn't make any sense I think, because first you exit the application and then you try to hide the icon... ???

 

When my system tray icon doesn't go away, i always place

this.notifyIcon.Visible = false;
this.notifyIcon.Dispose();

in the Closing event of the form.
