Hi all,

Attached is a custom control that will enable full blown comet (async) capabilities to your site. The custom control is a wrapper around the frozenmountain.com comet implementation. The control is using the hosted model provided by frozenmountain where the long-polling tcp connections are handled by their servers.

The demo is build using webgui 6.3.11

The demo app has

- WebSyncControl - custom control (really the client control but also has the server eventhandler for incoming messages) that needs to be added to a form with some connection info set (seem demo form1.cs)

- WebSyncManager.cs which is a c# class used to perform publishing

- WebSyncProxy.aspx which is needed if you want to use private keys for connecting/subscring to channels

This will add comet capabilities to you site in a manner of minutes!!

Ping me if you have any questions daniel[dot]dekkers[at]hotmail[dot]com

Cheers,

Daniel
