This demo uses WebSync and the ExtJS Grid component to build a simple stock ticker.
For more information on building high-quality stock tickers using WebSync, including some tips on how to set up your channels and distribute data efficiently, read our blog post on the subject.
Use WebSync with other 3rd party components to create incredible mashups.
Drag and drop the map, add waypoints, zoom in and out, change the map style, and watch as your changes are instantly synced up with other users.
Building on the ExtJS stock ticker is an implementation of the same idea, this time using Silverlight.
This is a rather trivial example that shows how you can let users interact with each other in real time by visually displaying each users color selection.
The "hello word" of comet solutions is arguable either the stock ticker or the live chat.
This example goes beyond the basics by keeping a list of current participants and by demonstrating instant notifications when users abruptly leave the chat by closing their web browser.
Special thanks to Bruno Tavares for building this.
Let users interact not only with elements on your page, but also with each other.
As you move elements around on screen, other users will see those elements move as well.
This demo is a basic example of a chat demo. Nothing fancy, just allows sending of messages back and forth, and pre-loads the last 20 messages from a server-side store.
