[RESOLVED] Show BalloonTip for systray icon without the Windows XP "pop" sound?

In my application I make use of balloon tip for a icon I put in the system tray. Every time the code trigger the balloon tip to show up, like I want it to do, I hear the windows "pop" sound that is associated with this type of action. Is there a way to show a balloon tip quietly? ( Running Windows XP)

I don't think it's possible on an application by application basis. There is a registry key that defines the sound file to be played, at:

HKEY_USERS\DEFAULT\AppEvents\Schemes\Apps\.Default\SystemNotification\.Current

By default it's %SystemRoot%\media\Windows XP Balloon.wav

You could modify that but it would switch the 'Pop' sound off for all System Notifications (not just your app)

Try using the following with the nid.dwInfoFlags member.
Private Const NIIF_NOSOUND = &H10

Thanks again! The NIIF_NOSOUND flag worked.
