They do it by using an asynchronous protocol. RTMP is the same protocol used
by Flash Media Server and Connect. The server keeps track of registered
connected clients, and broadcasts messages to all of those clients.

You can approximate this functionality using AMF and polling, which is what
the Messaging component of BlazeDS uses. You don't get messages immediately,
though, since it's client-pull rather than server-push.

RE: page self refresh whenever database gets new input

2008-06-23 Thread Brad Wood
This may be a hand grenade for your ant, but I've got to throw it out
there since no one else has.

Flex LiveCycle Data Services
(http://www.adobe.com/products/livecycle/dataservices/) allows the
server to "push" messages to the client which means a users page could
refresh data without having to be refreshed or "poll" the server.

I'm not sure how they do it, but it might be similar to how SeeFusion's
Flex interface will stream data to the client indefinitely by keeping a
TCP connection open and pushing XML down the pipe.

Subject: page self refresh whenever database gets new input

Hi,

I'm having a system that has two different consoles one for people input
data, and other for people view data. One isn't connected to the other.
Meaning, they work separatedly but at the same time. If there is a new
input, then the new input will show on the diplay console right away, no
need to hit any key nor button to refresh the page. The idea similar to
MS Outlook. Whenever a new mail comes, it just shows up by itself. Or
just like a stock reports with live feeding.

Is there any way to do this in cold fusion ? Database is MS Access.

Thanks

Anthony

Re: page self refresh whenever database gets new input

2008-06-21 Thread Dominic Watson
I can't give you sample code, no. It is far too broad a topic and there is
heaps of info at the end of a search engine. However, the idea would be
something like:

Sys admin page


Do Loop every x seconds
Request user data through js ajax -> request would be to a url that would
point to your cfm/cfc that will output the data (as either JSON or Xml)
Update user data display
End loop

To do it this way with ajax you will need to do some learning. You need to
know / do:

a) Basic ajax fundamentals
b) Pick an ajax library or use your own (libraries include, Spry, Ext,
JQuery, cfajax...) and figure out how to use it
c) Figure out how to load data using the library you choose and display it
in page
d) Figure out how to continually request the data at a given time interval

I've have used Spry very briefly and have found it extremely easy to learn
and quick to get going with.

RE: page self refresh whenever database gets new input

2008-06-21 Thread Eric Roberts
I would jus have a periodic refresh of the page...there is nothing that
could "detect" a change then cause a refresh that I could think of...though
that would be cool.  Set a metataq refresh to occur every x number of
seconds as appropriate for the frequency of user input.  Even outlook checks
mail to see if there is new mail and refreshes the window with each check.
If there is no email, you really don't see anything.

Re: page self refresh whenever database gets new input

2008-06-21 Thread Dominic Watson
This would involve a client side language (ie. javascript) to repeatedly
request the new info; ColdFusion can only act server side. I'd say some kind
of AJAX setup will be the ideal solution as opposed to some javascript that
constantly auto-refreshes the page.
