Id tend to agree with jhance on #1, however could you go into greater detail as to what you mean by block all traffic? &nbsp;Maybe describe in a little more detail the design of your program. &nbsp;Are you trying to stop communication internally to your app or throughout the entire system?<br />

mulitthreaded/iterative/as<wbr />ync/overla<wbr />pping? server/client? etc...

I nned my app to be able to block all internet traffic, but I am not a networking programmer so I've no experience in this. I guess blocking the ports for TCP/IP communication is what I want to do (and of course enable it again as well). Is there any way to do this without a lot of complex networking knowledge? I use Norton Internet Security 2003 and it notably has the kind of thing I need for this project as one of its features. You can click a button to block all traffic and resume it any point.

I need an application I am writing in C++ to be able to use WinSock (or other method) to block all TCP/IP sockets at the click of a button (and obviously resume the traffic). Does anyone how I would go about this in C++? Thanks.

Winsock

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
