Introduction
First of all, let me say that this is my first gadget attempt and I have the intention to update this tool.
Do you remember Screen Snaper? It is the free tool that I created and for which most people asked me for the source code of the library SnaperHelper.dll.
Good news for you!
I am proud to present a new gadget version of this tool designed for Windows Vista SideBar and which includes all the source code.
Note: In this article, I will not explain all the code in detail.
Description
Screen Snaper is a powerful, flexible and intuitive screen-capture utility. It allows you to capture anything on the screen.

Basically ScreenSnaper is composed of three principal components:
