Disabling internet connection?

Does anybody know of a program or a way to create a keyboard shortcut to disable internet connection, even when I'm in other programs? If it is a program, I need one that does not require me to select it before I can disable my internet connection as I wish to disable my connection while in a full screen program and i do not wish to [alt]+[tab] out of it. For example, something that might disable my internet connection when I press a key in full screen mode of a game.


[Note] I have dev-C++, so if you know how to program something like that please give me the code so that i can copy and compile it into a .exe file.

Reply:No, sorry. I think you will have to unplug the power cord to your DSL modem.
Reply:Put an administrator password on your computer and then open your firewall and block PORT 80 which is the port used for http. Another easy way is to assign a static IP to your computer and then block port 80 from the router. It's all up to you and your situation.
