Answer 1

Use the Resize event.

Use this event to detect changes in the size of your form. When the form is minimized to the tray, the WindowState property will be set to FormWindowState.Minimized.

Show the balloon-tip

When the form is minimized, you can call the method ShowBalloonTip on your notify-icon.

Here's an example:

Private Sub OnResize(ByVal sender As Object, ByVal args As EventArgs) Handles Me.Resize

    If WindowState = FormWindowState.Minimized Then

        'To hide the form
        Hide() 

        'This line does the magic (parameters: timeout in ms, title, text, icon)
        MyNotifyIcon.ShowBalloonTip(3000, "MyApp", "The app was minimized", ToolTipIcon.Info)

    End If

End Sub
