C# NotifyIcon ShowBalloonTip timeout

In my c# (2.0 framework) application I'm using notify Icon control. I want to show from this control a balloon tip. but the "showBalloonTip" event i slimite to a timeout and I want to show this balloon forever. I've tried to开发者_开发百科 use a timer that will show the balloon again and again but in vista there is a fading effect for balloons and if it is not disabled every 25-30 seconds the balloon will fade in.

Any idea?

Thanks.

The balloon is faded by default and it's part of the Windows common behavior. You can't adjust it. What you could do is create a form, place is manually next to the toolbar region and display it topmost (but non-dialog) and use the BalloonTipShown event to override the display of the actual balloon.
