Dear All,
I have a live streaming channel display in the site, and i wanted to announce live broadcast to the users by refreshing the page when live broadcast starts. So i made a module that has only a text saying live broadcast is here, and in that module (which is hidden unless at time of live streaming) i added a javascript that refreshes the page using this code:
setTimeout("location.reload(true);",10000000);
just to be able to refresh the page once, till the live broadcast finishes then I make the module hidden again so i guarantee with the very big time value that it is only refreshed once.
However, nothing happens at all, if I am opening the site already I have to press F5 to get that text and see the module visible..
My question is, how do I push the page through the open sites in browsers already so that users know there is broadcast now without them pressing F5 every few seconds please?
Thanks a lot

Hello Mitchel,

Thanks for your answer..but i sitll can't get it! I searched for Javascript Server PUSH code...and i found something called Comet ..but it talked mostly about PHP...and it was too complicated i coudlnt understand it...can you provide me with a sample plz? anythign might help...

I cna't understand why is this so complicated!! i thought it was just a screen refresh! but when i implemented it i found out it refreshes the current user screen only, and it doesnt refresh all the open browsers screens...

Thanks alot...

but i don't know how to add ASP.Net code to an html module?? i thought i only add javascript code??

i can tsearch for that control, but where can i read about adding asp.net to DNN html module plz?

Thanks

Well, do you know someoen to make a custom development for me plz? i asked some good companies and they told me it takes 10 hours with a big rate like 75$ an hour!! juhst for somethign simple like that!!" border=0>

Do you knkow someone who can take like 100 $ max plz to do it for me?

Thanks.

you mean this code is ok but i should just make it less than two hours?

But the problem is i don't want to screen to refresh more than once or twice only! not every few seconds...and i searched for a code that refreshes the screen once only and i got this one, which refreshed the current user browser only and not other open browsers, you see i opened the site with another browser, and waited for any refresh to happen so that the module (with a sentence saying WE ARE ONLINE NOW ) is appearing, but nothing!

[script removed] //  Published at: scripts.tropicalpcsolutions.com
var reloaded = false;
var loc=""+document.location;
loc = loc.indexOf("?reloaded=")!=-1?loc.substring(loc.indexOf("?reloaded=")+10,loc.length):"";
loc = loc.indexOf("&")!=-1?loc.substring(0,loc.indexOf("&")):loc;
reloaded = loc!=""?(loc=="true"):reloaded;
function reloadOnceOnly() {
    if (!reloaded)
        window.location.replace(window.location+"?reloaded=true");
}
reloadOnceOnly(); //You can call this via the body tag if desired
[script removed]
 

Ok so to make sur ei understannd you correctly, if i use this line:

setTimeout("location.reload(true);",60000);

this will poll the server FOR ALL USERS OPEN BROWSERS every one minute...right? and not only on the open user browser right?

Thank you so much for your help i truely appreciate reaching a conclusion from an expert like yourself Sir.

Best Regards

Nehal.

Hello Again Micheal,

I hope i am not bothering you again" border=0> but i found this very interesting polling code which is supposed to poll the server only if it changed so i am assuming then it wont refresh except once??

http://ajaxpatterns.org/Periodic_Refresh

this is the part i am internested in:

this.timerID = setInterval(function () { thisObj.get(true); }, interval);

get() performs a straightforward query of the server:

 this.httpGetObj.open('POST', this.url, true);
 this.httpGetObj.setRequestHeader('Content-Type','application/x-www-form-urlencoded; charset=UTF-8');
 var thisObj = this;
 this.httpGetObj.onreadystatechange = function () { thisObj.handleGet(system); };
 this.httpGetObj.send(param);

Do you think thisi will work? i don't know how to try it! i mean, how do i use the timerID?? or should i ignore the timerID and just use setInterval(function () { thisObj.get(true); }, interval); and i set interval to say 30 seconds? hoping it won't refresh except once?
 

Its ok, i discarded it...I tried the setTimeout("location.reload(true);",30000);

to refresh the page every 30 seconds. But consider this scenario:

1-user A has his browser open

2-I make my hidden module visible (the one that has the above setTimtout code as well as text saying WE ARE ON AIR NOW)

3-Nothing happenes to the user A screen at all EXCEPT AFTER HE PRESSES F5

And that is not what i want, i want the user who has his browser already open to get the WE ARE ON AIR notification without having to press F5.

So, any clue how should i do that? os that's what you suggest to have it custom made? Do you knwo of any module to be purchased from snowcovered that does that even Micheal?

Thank you so much.
