C# Fade Out

[flareback]

I have a form that I'm make using Visual Studio with c#. I wanted to have a fade out effect, but it flashes when it starts and makes it look bad. Anyone know of a way around this? I've tried searching and everything I've read is people have a problem when fading in but not out.

 

The program is for a tablet pc so i don't think many of you will be able to use the whole thing but the part dealing with the fade is below. and the whole thing can be found in a zip file here or I have created a smaller part with just the annoying part that flashes and doesn't require a tablet pc to run but does require visual studio 2005 here

* Note to use the first version you must create a circle by drawing a circle which creates a nice pretty circle. Then do a ChevronDown gesture inside the circle. Then hit save to see it fade out.

* Note to use the second version simply hit the save button to see it fade out.

 

The methods for fading in and out are at the bottom. The top is setup for the form. I doubt just copying and pasting this into something will work as visual studio likes to add a bunch of other things, this is just what I wrote.
