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!
Looks like you forgot to set the Icon for it like this
notifyIcon1.Icon = SystemIcons.Exclamation;
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(5000, "Welcome", "Hello " + User, ToolTipIcon.Info);
