Answer 1

In WinForms you'd need to use timers or something to animate the opacity of the OK or FAILED control to make it fade out, or do something similar using GDI+ to draw it manually.

If you're using .NET 3.5 anyway, I'd recommend using WPF, which is much easier for doing that sort of thing.

As an example, you can have a look at Scott Hanselman's Baby Smash app, which is open source and has a similar concept of fading things in and out.
