Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Why don't you try and write a firewall rule rather developing an application for that .Developing firewall is not an easy task and especially with framework like .net it has a lot of security loops.My best suggestion would be to create a rule on the firewall to block the user action.If you are hell-bent on creating a .NET application

Create a windows service to listen to all OS events
and capture and block the events that allows the Download dialog and Open File dialog to occur,but you have to make sure that those events are triggered by a browser,or else you'll be blocking all calls to those events.

This would be great if you could tweak in a little to read from the service into a web page
