Problem with balloon tips

HI,

I create balloon tips all over our application. My problem is that all of the balloon tips stay on the task-bar and needs to be hovered over for them to disappear.

        public static bool SetBalloonTip(string balloonTipTitle, string balloonTipText, ToolTipIcon balloonTipIcon)
    {
        bool result = false;
        NotifyIcon notifyIcon;

        try
        {
            notifyIcon = new NotifyIcon();

            notifyIcon.Icon = SystemIcons.Information;
            notifyIcon.BalloonTipTitle = balloonTipTitle;
            notifyIcon.BalloonTipText = balloonTipText;
            notifyIcon.BalloonTipIcon = balloonTipIcon;

            notify开发者_开发技巧Icon.Visible = true;
            notifyIcon.ShowBalloonTip(30000);

            result = true;
        }
        catch (Exception)
        {

            throw;
        }

        return result;
    }

My question is, how do i make the notify icon disappear after it has been shown?

Found a solution:

first:

private static System.ComponentModel.IContainer components;

Second:

public static bool SetBalloonTip(string balloonTipTitle, string balloonTipText, ToolTipIcon balloonTipIcon)
    {
        bool result = false;
        NotifyIcon notifyIcon;

        try
        {
            if (components == null)
            {
                components = new System.ComponentModel.Container();
            }

            notifyIcon = new NotifyIcon(components);

            notifyIcon.Icon = SystemIcons.Information;
            notifyIcon.BalloonTipTitle = balloonTipTitle;
            notifyIcon.BalloonTipText = balloonTipText;
            notifyIcon.BalloonTipIcon = balloonTipIcon;

            notifyIcon.Visible = true;
            notifyIcon.ShowBalloonTip(30000);

            result = true;
        }
        catch (Exception)
        {

            throw;
        }

        return result;
    }

Third:

        public static void DisposeOfBallonTips(bool disposing)
    {
        try
        {
            // Clean up any components being used.
            if (disposing)
            {
                if (components != null)
                {
                    components.Dispose();
                }
            }
        }
        catch (Exception)
        {

            throw;
        }
    }

Calling DisposeOfBallonTips when i want to clean up all NotifyIcons.

Are you displying more than one balloon at a time?

From MSDN:

Only one balloon tip can display on the taskbar at a time. Attempting to display a balloon tip when one is currently displayed on the taskbar causes the timeout value to be ignored.

I'm mostly guessing but try this

add an event handler like this and see if it helps.

     ...
     ... 
     notifyIcon.BalloonTipClosed += new EventHandler(notifyIcon_BalloonTipClosed);
     notifyIcon.ShowBalloonTip(30000);
     ...
}



static void notifyIcon_BalloonTipClosed(object sender, EventArgs e)
{
    ((NotifyIcon) sender).Visible = false;
}
