Hi Martin,

Problem solved..
I can add new subscribe and remove old subscribe in the runtime.

Thanks,
Alex

Hi Martin,

I am using your c# binding and have another question for pub/sub.

I create a subscriber to connect to the publisher. Can the subscriber in
runtime change the topic subscriptions?
e.g. s.SetSockOpt(ZMQ.SUBSCRIBE, XXX); s.SetSockOpt(ZMQ.SUBSCRIBE, YYY);

after the socket is created and connected?

Regards,
Alex

Alex,

> I tried Jeff version and your version and can't get them work.

I cannot answer for the Jeff's version. However, for my version the 
SetSockOpt takes a simple string as a parameter:

s.SetSockOpt(ZMQ.SUBSCRIBE, "");

For an example, have a look here:
