Capturing Another Application's Network Traffic

[aldente]

Hi!

I am currently looking for an easy way to capture another application's network traffic in my program.

One way I found is the following: Create a local proxy, starting the other application and set it to use the proxy, like described on the following page: http://portswigger.net/misc/

But maybe someone knows a better method. It would be great if capturing the network traffic (incoming only), WITHOUT administrator priviliges, and even if the other application is ALREADY RUNNING.

Thank you for any advice!
