title: How to show non-interactive, auto-hiding notification popup message with Windows Forms in c#?
body: <p>Using Windows Forms, .NET 3.5 framework, language: c#
  I would like to show a popup window for 1 second to notify users of actions that are performed. For example, when I copy a file X I want to show a notification like "Copied file X to File X-copy". Should be shown for a second, then autohide.</p>
