Imagine me catching the connections of your Internet Explorer, when you're doing your banking Big Grin | :-D

I doubt that this is possible.

what program is it? and what exactly do you want to do with the connection?

your app is a game? if so then why do you not do the connection within your own app?

Unless of course your just trying to capture packets and manipulate them from some other game, i.e. some sort of hacking ability...

Last time I did anything like this I had to create an NDIS driver and capture the traffic at the network card. This is not for the faint of heart and if you mess it up you are likely to pull down the entire operating system.

Hi I have used multithreading for udp client/server communication.When i run the server both the threads are executing at the same time.So i used a Thread.Sleep() after the 1st thread.So the 1st thread works properly.When it comes to the 2nd thread it gives"the existing connection was forcibly closed by the remote host".Can you please give me your suggestion

is it because thread 2 is being called from in thread 1? it would be better if you could post some example code

An exception has been thrown by the type initializers for 'java.io.File'.

17-Mar-09 5:19

Sorry i didnt read the exception in your OP. That exception says that there is a problem with the host you are connected to. i.e. the server. This means the server is cancelling the connection for one reason or another, it could be your server is limiting connections to just one (your first thread) and thats why the second fails. I cant help much with this kind of thing, but you basically need to look at settings on your server somewhere.
