Thanks again Jarek If I wrap the bind in a try catch I get the following error message:
"Protocol not supported" I get the same exception thrown on the subscriber whilst trying to perform the connect(). This therefore probably has something to do with the ZMQ build on my platform. Do I need to pass any parameters or flags at compile time to have ZMQ support the protocol? Do I need to change any Windows OS settings to support this? FWIW, I've put the VS project here: https://github.com/JimmyReload/zeromq-snippets Thanks James On 27 November 2014 at 13:24, Dorvin <dor...@tlen.pl> wrote: > W dniu 2014-11-27 11:31, James Chapman pisze: >> I looked at the following example from the user guide: >> http://zguide.zeromq.org/cpp:wuproxy and tried to implement a similar >> example.
