flash 8 file upload, tracking up/down rate?

[webdreamer]

Is it possible with the new upload feature in flash it to measure and display the transfer rate just like the OS window?

[EQFlash]

try this.
create a progress bar movieclip
and instance name it pbar
add this code to the script that uploads the file.

pbar._width = 0
listener.onProgress = function(selectedFile:FileReference, bytesLoaded:Number, bytesTotal:Number):Void  {
	pbar._width = (bytesLoaded/bytesTotal)*100
};

[webdreamer]

Thanks but not quite want i ment.

[McUsher]

Well why not simply use getTimer() at start and end of down/upload
and calculate speed with the FileReference.size property?

[webdreamer]

I am looking to display the current transfer rate. What your suggesting can only be done one upload/download is complete.

[McUsher]

Well no,...

Check FlashHelp for the FileReference
there is the
onProgress (FileReference.onProgress-Ereignis-Listener)
onProgress = function(fileRef:FileReference, bytesLoaded:Number, bytesTotal:Number) {}

event, combined with the getTimer() you can achieve, what you want.

[webdreamer]

code:

---

pbar._width = 0

listener.onProgress = function(selectedFile:FileReference, bytesLoaded:Number, bytesTotal:Number):Void  {

	pbar._width = (bytesLoaded/bytesTotal)*100

};

---

This i know. But to then take that and use getTimer() in some way to get current transfer rate i dont.

import flash.net.FileReference;

var listener:Object = new Object();
var startTime:Number;

listener.onOpen = function(file:FileReference):Void  {
    startTime = getTimer();
    trace("download of "+file.name+" started at "+startTime);
};

listener.onProgress = function(file:FileReference, bytesLoaded:Number, bytesTotal:Number):Void  {
    var millisecsPassed:Number = getTimer()-startTime;
    var rate:Number = Math.round(bytesLoaded/millisecsPassed*1000);
    // rate will be bytes per second average during the whole download
    trace("bytesLoaded: "+bytesLoaded+" bytesTotal: "+bytesTotal+" @ "+rate+" bytes/sec");
};

listener.onComplete = function(file:FileReference):Void  {
    var millisecsPassed:Number = getTimer()-startTime;
    var rate:Number = Math.round(file.size/millisecsPassed*1000);

    trace("onComplete: "+file.name);
    trace("total Time: "+ Math.round(millisecsPassed/1000)+ " seconds ");
    trace("Overall Performance: "+rate+" bytes/sec");
};

var fileRef:FileReference = new FileReference();
fileRef.addListener(listener);
var url:String = "http://www.macromedia.com/platform/whitepapers/platform_overview.pdf";
if (!fileRef.download(url, "FlashPlatform.pdf")) {
    trace("dialog box failed to open.");
} 

... just because i feel happy today...

[webdreamer]

You should be happy more often

Cheers man....

[McUsher]

To be honest, it was just the MM Demo code in
the AS-Reference help section + this getTimer() thingy

[webdreamer]

lol. I did a lot of reading of the helps files regarding this issue. dont know how i missed it.

thanks again.

worked a treat

[shendel101]

how about the decrementing time left? how is it done? thanks..

[webdreamer]

how about the decrementing time left? how is it done? thanks..

Whats the question?
this thread is nearly two years old.

[shendel101]

i made search of my problem.. and i got this post same as my problem.. i am wondering if you could help me as you already figure out how, two years ago..lol.. My problem is to display time left of download and upload time.. In this example it is incrementing.. what i need is decrementing.. Hope you could help me please.

[shendel101]

thanks for the help.. i was counting you could help me..
