Ever wanted to use .config files but hesitated because you were not able to write to them? This class allows you to easily write and read from .config Files. The class works (thanks to reflection) both in debug and release mode without any changes. Because the default .config Provider will not reload any configuration without reloading the application this feature is also implemented via a filesystemwatcher that looks for changes on the app.config file. The original implementation can be found on www.angrycoder.com developed by Joel Martinez in C#. Visit www.visualsoft-net.de to download this code and much more vb.net, vb6 and c# samples

UPDATED 03/JAN/2010: This is a file upload class with a demo page. Very easy to integrate into existing projects, it only requires three steps. The code is nicely commented and formatted. I've also added JavaScript code that disables the Submit button and shows an image and message informing about the upload. If you use Norton AntiVirus you will need to disable your Script Blocking for the file writting to work. The code can support uploads of up to 2GB or so, but I've only tested it with files of up to 30MB. It also supports the configuration of allowed extensions for more security. If you like this code, please vote. Last Update: Added code that takes care of a IIS vulnerability involving semicolons in file names (extremely important!).
