Sockets firewall problem

[Boni]

Dear all,
I am trying too use sockets for IPC communication on one and the same
machine. When following code is executed windows firewall pops up. Is there
any possibility to use sockets without a risk to be blocked by firewall.
private void ListenIPC( ){

while(true){

TcpListener tcpListener = new TcpListener(10);

tcpListener.Start();

You need to use the Windows firewall API to open a port to yourself to make
it work in all cases.

Hi Carl,
is there any simple sort of IPC between managed and unmanaged on local
machine which is bidirectional, fast and don't care firewalls?
Thanks a lot,
Boni

Named pipes would seem a logical choice. Another option would be something
custom built using shared memory.

These articles might help you.

The .NET articles are in C#. if you use MC++ or C++/CLI for your managed app
you can simply translate them. the classes and methods stay the same.
