Hi all, 

I would like to retrieve  the number of node registered in the OpcUA server without read all the nodes.

(for example to do a progress bar). I had a look on the Browser object but i didn't find the information.

Thank you very much for your reply.

Regards, 

Pascal

Servers often don't know this information and can't publish it so there is no way to get it.

In any case, you should not need this information. You should never be doing things like "reading all nodes in a server" since servers can easily have millions of nodes that remain dormant until a client has a use for it.

You need to think about what you are trying to accomplish if you think you need this information.
