Client Server Networking Problem

[pattie]

Both clients can ping the server using either the IP address or the name

Hi guys:

I think you might want to take a look at the sendAll function. It looks like it does not send the events to the clients (server works fine).

Is it a bug in the client server code or did I forget something?

Are you using Vizard 2.5? Because the viznet module will only work with Vizard 3.0

[pattie]

I am using the very last version on all machines

[farshizzo]

I tested the sendAll command and it worked fine here. Can you post the scripts you are using? Also, in the future, please post Vizard 3.0 related question in the Vizard 3.0 forum.

Sorry about posting this thread in the wrong place.

Here is the code I am using:

Hi,

Can you repost the code using the special code tags?

[code]insert code here[/code]

This will preserve the indentation in the code.
