[Flashcoders] IOError on https under IE7
I have a swf that is being loaded off of an https server. As it fires up, it attempts to call a simple authentication service that lives on the same host. This works fine under Firefox, Opera, and Safari. However, under IE, it throws an exception: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: https://host/path/script.php?username=allaryin&passwd=hash";] Obviously, if I just load the url directly into IE, it loads fine. This problem only occurs when flash tries to load the url for me. When I monitor the query with Charles, it shows that the request is being made correctly and that the information I am expecting is successfully being returned. However, Flash is apparently ignoring the response. This behavior has been observed on different machines, running both XP and Vista. Thoughts?

Grin. Well, he said OO best practices, not ActionScript ;) Traditional OO design rules state that you should always encapsulate your instance data in getters and setters. The general idea being that external classes should never have the ability or need to manipulate your data for you - they should have to ask nicely and then accept whatever you're willing to do in stead. And I agree with that for the most part. While I can understand the use of public instance variables in AS2 and AS3 them because of backwards mental compatibility with AS1... I only use them in AS2 when the project already does - which is often since most of the AS2 I work with was written by former AS1 devs ;) It's also kind of unreasonable to expect people to use private properties in such a weakly typed language anyway. I find this regrettable in AS2 but acceptable in AS3 since you can still just hook into the property and listen for changes and respond accordingly. That gives you the control you need to safeguard your internal data.

When it comes to "best" practices, the best thing you can do is be consistent. Whether that means consistent with your other library of work or consistent with the rest of the code in a project you have joined, making your code as reliably similar to other associated code should probably be your highest priority. Thus, if you are editing a class that uses underscores for instance variables, you should too. If they don't, then you probably shouldn't either - it gets confusing fast. Personally, I do lean toward using underscores for my instance variables if I can get away with it. This allows for a clean distinction between instance and local variables and is a very easy habit to get into. It's certainly a whole lot nicer and easier to parse visually than having bunches of myThis and myThat ;) It is especially handy to use underscores when you are writing getters and setters for those variables to further distinguish them - you don't have to pick a different name for your public property. And since we're talking best practices, you don't have any public instance variables anyhow, hmm? :) Some people will use two underscores for private vars and one for protected or will come up with some other way to use more underscores. I would recommend against mixing and matching - that degrades readability and gets confusing. You should use either one or two... and two doesn't really gain you anything. I don't know when the last time I used two underscores before a variable name was. Probably in another language when I'm not camel casing things, private instance vars might be named __core_temperature, or something like that. But it's been a while, and since the AS convention is camel casing... consistency above all else ;) Ammon ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
[Flashcoders] zinc instability
Ok, so I've finally upgraded from the trial to a full licensed version of Zinc. I have a swf that when compiled on this machine segfaults immediately. Other swf's compile just fine, it's only this one file. I uninstalled the trial, the full version, even the mProjector demo that was still floating around on the machine. Rebooted twice. Reinstalled Zinc. No change. On a neighboring machine (which never had the trial installed), I did a fresh install and the troublesome file builds into a lovely exe w/o a hitch. So, my question is this. Have other people had similar reliability problems with Zinc? Is there any procedure I can go through to beat this into submission so I don't have to switch workstations to build?

Yeah, we did need the transparent because of the skin we were using
for our player. We actually had a discussion about the wmode parameter
in this office last week but it seems to work reliably in all modern
browsers these days?
Unfortunately, removing the wmode setting didn't actually make any
difference in this case. (We removed _all_ parameters and just tried
using the default settings for one run).
Anyhow. Issue has been resolved for now.
Thank you JC, Mike, and Jim. :)

That might have helped, but the problem wasn't with loading the SWF. It was with the SWF in turn loading the FLV. We had the following structure: something.html /dir/something.swf /dir/something.flv The SWF itself was then trying to load the FLV from the same directory. This worked in flash 8 and in flash 9 for firefox. Unfortunately, flash 9 for IE apparently told the SWF (somewhere... not in _url as just proven) it lived in the same folder as the HTML... not where it was actually being loaded from. Again, we found a workaround. By making the swf more generic and passing in a parameter telling it where to find the video, it seems to work reliably across different plugin versions.

YES I could see other SWF's in that browser. Sheesh. Anyways. Resolution to the problem has been achieved. In stead of hard coding the flv into the swf, we're passing it in as an argument when instantiating it from the html. And it works. There seems to be an issue with directory locations. The flv was trying to load relative to the swf, NOT the html file. So why this happens in flash 9 for IE, I don't know, nor do I care any more at this point. But the incident has been logged for future reference when we encounter the bug again.

[Flashcoders] flv not playing in IE with Flash 9
Ok, simple issue really, and I seem to have found evidence of other people experiencing it as well - just no answers posted to their pleas for help :) I have a flash video (the player swf is compiled for flash 8) that should be visible at the bottom of http://walk-ez.com/fans.aspx. And it is visible. Under Firefox and Opera. Under IE, it does not work on machines with flash 9, only those that have yet to be upgraded from 8. I've tried with and without fla-i mean swfobject, with and without various parameters being passed in to the swf, and off of a variety of servers. None of this seems to make any sort of difference. Thoughts? Is this a known issue?

re: [Flashcoders] Array Empowerment
A few thoughts on optimization. Just thoughts.
Steven Sacks | BLITZ wrote:
// Remove all elements from Array

This function scares me to death. I understand that the garbage
collection in any decent VM should take care of this... but wow, it
feels like some dangerous voodoo. :)
// Removes all null and undefined elements from Array
Array.prototype.compact = function() {
this.delete_all(null);
this.delete_all(undefined);
};
Which is faster, iterating over an array of size N once and checking
for elements that are either null or undefined in a single pass, or
iterating over an array of size N checking for nulls and then
iterating again over an array of size N-x and checking for the
undefineds?
// Deletes items from the Array that are equal to obj
Array.prototype.delete_all = function(obj) {
var i = -1;
var a = this.length;
while (--a -(-1)) {
if (this[a] == obj) {
i = a;
break;
} else if (this[a] instanceof Array && obj instanceof
Array) {
if (this[a].eql(obj)) i = a;
break;
}
}
if (i > -1) {
this.splice(i, 1);
this.delete_all(obj);
}
};
You do this sort of thing in several of your functions and I think you
_might_ be able to squeeze a bit of theoretical speed out of things by
if obj is an array
loop checking for array equality
else
loop checking for value equality
In stead of
loop over the entire array
check value equality
if obj is an array
check array equality
It's not much, but over a few thousand comparrisions it might make a difference?
Also, what's the performance hit for splice()? I know it's bad in some
languages. Would it be potentially faster to build a new array in
stead of re-splicing the old one? I guess it depends on the length of
the array as compared to the number of elements being removed. What is
the threshold where one becomes preferrable to the other?
// Runs a function on every item in the array
// Returns an array of all items for which the function returns true.
Array.prototype.filter = function(block) {
var r = [];
var n = this.length;
for (var a = 0; a < n; a++) {
if (block(this[a])) r.push(this[a]);
}
return r;
};
I love this one. I use it absolutely all the time in other languages.
