What Attributes are you seeking for the entity? Are you looking for table/column specific information, or are you looking to simply return a set of rows out of a table for a given query? Please elaborate.

You can send any type of data, the port is just the "channel". Most firewalls that I'm aware of don't actually inspect the packet data, rather they examine the source/dest IP and/or the source/dest port numbers. Because DNS is such a fundamental part of how the internet works, nearly all firewalls will allow traffic through on that port figuring it's probably legit DNS queries. Video games, or any other app, will exhibit this problem if a device along the way is blocking traffic. The source/destination port can also indicate the type of application on both ends -- server apps will bind to ports 1-1024 whereas "user" apps will typically use higher numbers like 50000-60000. Some firewalls/admins exploit this by only allow traffic through if the dest port num is under 1024.
Also -- are you able to ping between your source and destination machines when trying to run in "global" mode? I ask this because if you're behind a router doing DHCP, at one or both ends of your pipe, you will not be able to directly "see" the remote machine without setting up port forwarding or DMZ access on the offending router. You mentioned video games -- your XBOX/PC usually won't work or accept incoming connections if you're behind a cable modem AND a router+switch unit -- until you configure "DMZ" on the router+switch unit.. My apologies if I'm preaching to the choir on this just wanted to throw it out there!
HTH if not post up again buddy.. Good luck

Hello, you need to decide how you want to persist the new item you are adding to the combo box. Every time you start/stop your application those dynamically added items will be erased from memory unless you store it to disk or database. Decide if you need to store it in a database (Access, SQL Server) or on disk (XML, Dataset, flat text, CSV, etc). This is up to you and how you decide to build your application...
Here are a few links to point you in the right direction..
