Question

i am using this code under my form1_load

notifyIcon1.Visible = true; 
notifyIcon1.ShowBalloonTip(5000, "Welcome", "Hello " + User, ToolTipIcon.Info); 

I even checked my registery and the value was 1. Why is the baloon not showing?
I do have a icon form my notify icon. and it is showing up. The Baloon is not though!

Answer 1

You may need to post the rest of the code that’s in your form’s load event, but here’s a couple of suggestions:

1. Make sure the form’s Load event is actually hooked up.
2. Make sure you’ve assigned an icon for the notify icon.

Also, note that the balloon tip isn’t guaranteed to show. See the Remarks section on msdn’s NotifyIcon.ShowBalloonTip Method article:

Remarks
Minimum and maximum timeout values are enforced by the operating system and are typically 10 and 30 seconds,
respectively, however this can vary depending on the operating system.
Timeout values that are too large or too small are adjusted to the
appropriate minimum or maximum value. In addition, if the user does
not appear to be using the computer (no keyboard or mouse events are
occurring) then the system does not count this time towards the
timeout.

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. The behavior is
slightly different depending on the operating system and whether the
balloon tip is from another, or the same, application. When the second
balloon tip is from another application, the first balloon tip will
display for the minimum timeout value before the second appears,
regardless of the value of timeout. In most cases, if the balloon tips
are from the same application, the first balloon tip immediately
closes when another call to the ShowBalloonTip method is made. In some
cases the second balloon will open on top of the first balloon.

The title text will display in a bold font near the top of the
balloon.
