private void button1_Click(object sender, EventArgs e) { NotifyIcon ni = new NotifyIcon(); ni.BalloonTipTitle = Application.ProductName; ni.BalloonTipText = "TEST BALLOON MESSAGE"; ni.Icon = Icon.ExtractAssociatedIcon(Application.ExecutablePath); ni.Text = Application.ProductName; ni.Visible = true; ni.ShowBalloonTip(5000); System.Threading.Thread.Sleep(5000); ni.Dispose(); } |
Disposeしないとアイコンが消えないのでNotifyIconはメンバーとしてもったほうがいい。
