问题
I have created a network trouble shooting tool in flash. The design will have all the componenets on the screen. I have to ping to every component once in minute. I have finished the design part.
Please someone help me how do i ping a webaddress or IP in flash.
I need a sample code.. Im using Flash CS3

What do you mean by you have all the components on the screen and you have to ping every component once in a minute?
If by ping you mean an app, what checks the time-response of a url, then you can try to play with this code:
var ldr:URLLoader = new URLLoader();
ldr.addEventListener(HTTPStatusEvent.HTTP_STATUS, ldrStatus);
var url:String = "URL-TO-SITE";
var limit:int = 10;
var time_start:Number;
var time_stop:Number;
var times:int;
ping();
function ping():void
{
trace("pinging", url);
times = 0;
doThePing();
}
function doThePing():void
{
time_start = getTimer();
ldr.load(new URLRequest(url));
}
function ldrStatus(evt:*):void
{
if(evt.status == 200)
{
time_stop = getTimer();
trace("got response in", time_stop - time_start, "ms");
}
times++;
if(times < limit) doThePing();
}
This is nothing special, the URLLoader
tries to load the url, and listens to the response. If the status
is 200
, then got a successful "ping". Or pong.
On the other hand, you can always run a server-side ping program, and control that with flash.
If you mean an app, like an upload-download-speedtester, that also starts with something like this, but rather with the Loader object.
Hope this helps.
EDIT:
Preventing cache problems, you can use:
ldr.load(new URLRequest(url + "?rnd="+Math.random()));
Now, this page might not give back the exact content of a site, but might be good enough to estimate the response time. With flash.
So overall, this could clear the cache and load the site everytime to give a better result.

In short, you can't.
In longer: you won't be able to ping, because a ping is actually an ICMP packet, and I don't believe Flash can send those. If there is some UDP or TCP service running on the machine you're trying to ping, though, AND the machine is running a socket policy server, then you would be able to use the Socket class to connect directly to that service (which could act like a ping).
