    <p>I wouldn't hold a game as old as PlanetSide up as a paragon of modern network implementation. Especially not having seen the insides of their networking library. :)</p> <p>Different types of communication require different methodologies. One of the answers above talks around the differences between frame/position updates and chat messages, without recognizing that using the same transport for both is probably silly. You should most definitely use a connected TCP socket between your chat implementation and the chat server, for text-style chat. Don't argue, just do it.</p> <p>So, for your game client doing updates via arriving UDP packets, the most efficient path from the network adapter through the kernel and into your application is (most likely) going to be a blocking recv. Create a thread that rips packets off the network, verifies their validity (chksum match, sequence number increasing, whatever other checks you have), de-serializes the data into an internal object, then queue the object on an internal queue to the application thread that handles those sorts of updates.</p> <p>But don't take my word for it: test it! Write a small program that can receive and deserialize 3 or 4 kinds of packets, using a blocking thread and a queue to deliver the objects, then re-write it using a single thread and IOCPs, with the deserialization and queueing in the completion routine. Pound enough packets through it to get the run time up in the minute range, and test which one is fastest. Make sure something (i.e. some thread) in your test app is consuming the objects off the queue so you get a full picture of the relative performance.</p> <p>Post back here when you have the two test programs done, and let us know which worked out best, mm'kay? Which was fastest, which would you rather maintain in the future, which took the longest to get it working, etc.</p>

    1. COBut I would hold a game as PlanetSide 2 as a "paragon" as it is an upcoming game built on the same patterns but probably on even more massive scale. I'm not advertising anything, just wanted to point out that my thoughts are definitely not utopian, because for some they may sound like those.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
