Load / unload a lot...

Hi there,
I'm working on an interactive presentation.
While clicking on buttons and text links new movies (swf's) pop up.
Each movie has a <close> button.
But i'm confused about how to use the 'loadMovie' and 'unloadMovieNum' with the different levels.
What is the best way to work this out and keep it workable.
I added an illustration of the 'presentation and it's functionality'.
I hope someone could explain me.
Thanx,
Pascal

if you use loadMovieNum() to load a swf into a _level, use unloadMovieNum() to unload it.
if you use loadMovie() to load a swf into a target movieclip, use unloadMovie() or, even better, use removeMovieClip() applied to the target movieclip.

Load / unload numerous images in air application (memory leak?)

Hi,
after struggling for a few days with this, I realized I need help!
I am trying to make an application load and display A LOT (hundreds) of images thumbnails at various position in a big area. The problem is that when I try to unload and reload images, I end up with an increasing memory, that does not get collected by the garbage collector.
My first challenge was to load images from anywhere in the computer (I am quite new to flex), which I solved by using a File reference and a Loader using the url extracted from the file:
               private function createImage():void {
                         var img_:String = "1905_a_mondrian.jpg";
                         var imageFile:File = new File();
                         imageFile.nativePath = imagesPath + "/" + img_;
                         var imageLoader:Loader = new Loader();
                         // useWeakReference permits the GC to collect the memory when the eventListener is dropped
                         imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded, false, 0, true);
                         imageLoader.load(new URLRequest(imageFile.url));
                         imageFile = null;
I make sure I remove the eventListener in the loaded method:
     e.target.content.removeEventListener(Event.COMPLETE, loaded);
And then Populate an external component:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
          xmlns:s="library://ns.adobe.com/flex/spark"

          x="-100" y="-100" width="200" height="200" >
     
     <fx:Script>
          <![CDATA[
               import mx.controls.Image;
               [Bindable]
               public var image:Image;
          ]]>
     </fx:Script>
     <fx:Declarations>
          
     </fx:Declarations>
     <mx:Image id="img_" source="{image}" horizontalCenter="0" verticalCenter="0" autoLoad="true" />
     
     <s:Ellipse height="4" width="4" horizontalCenter="0" verticalCenter="0" >
          <s:fill>
               <s:SolidColor color="0x00FF00"/>
          </s:fill>
     </s:Ellipse>
</s:Group>
I populate a Dictionary to keep a track of all the component created. Finally I nullify all that I can to hint the garbage collector.
Now I have a function to empty the Dictionary (componentBag below) when we want to unload the images:
               protected function button1_clickHandler(event:MouseEvent):void
                         for each ( var g : Group in componentBag )
                                   ((ImgPanel)(g.getChildAt(0))).img_.unloadAndStop(false);
                                   ((ImgPanel)(g.getChildAt(0))).image = null;
                                   delete componentBag[g.uid];
                                   g.removeElementAt(0);
                                   this.removeElement(g);
                                   g = null;
     triggerGC();
PROBLEM: using profiler, the loading/unloading works once or twice and after the memory keeps increasing... And if I launch the application, wait for a while and do a load/unload, the garbage collection only recovers a few megabytes, far from what was allocated for displaying the images.
What am I missing? Is there a problem with loading a lot of images? Has anyone done this?
In attachment is the full test code, the ImgPanel goes inside a 'views' package

Thanks to Anton_AL, I finally solved this problem by using an URLLoader AND a plain Loader:
var loader: URLLoader = new URLLoader( );
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, onLoadingComplete );
loader.load( new URLRequest(file.url) );
private function onLoadingComplete( e: Event ):void
     var loader: Loader = new Loader( );
     loader.contentLoaderInfo.addEventListener( Event.COMPLETE, onParsingComplete );
     loader.loadBytes( e.target.data );
private function onParsingComplete( e: Event ):void
     var img: BitmapImage = new BitmapImage( );
     img.source = (e.target.content as Bitmap).bitmapData;
     _images.push( img );
private function onImageLoaded( e:Event ):void
     var img: Image = e.target as Image;
     img.removeEventListener( Event.COMPLETE, onImageLoaded );
     _images.push( img );

Load/unload

Hi,
The question is for ASO specifically.
What would be the scenario where we need load/unload application/database scripts when we load the data?. Does it depend on the amount of data loaded or any other factor.?
Can we eliminate the load/unload part from the script. (Essbase services are stopped/started overnight, so I assume this will take care of writing everythign to the hard disk from memory).
Can you please share your thoughts on this?
Thanks,
Tom Thomas

I can see the rational for doing it. There are some commands that will fail if the ASO cube is not loaded (It will not be auto loaded) so people put in the load command to make sure it is running. As for unload, if you had limited resources on the machine or wanted to consume a lot of memory for an application unloading applicaitons not being used frees up those resources. So people will stop the application when done loading so it does not use any resources until someone needs it. This is especially important when you have a ton of applications on a server. I have one client with over 100 applications and if they start them all, they run out of memory. Most of the apps are historical and are used very little so during processing they start the app, do an export(makes sure the app is still working) and then stops it then goes on and does the next one

New HDD Load / Unload Cycle Count increasing extremely fast !

Hi all
I just upgrade my Pavilion dv5 HDD. The new model is Hitachi Travelstar 7K500 (HTS725050A9A364). However, I found my new HDD's Load / Unload Cycle Count increasing extremely fast!
Until now the number of Load / Unload Cycle is 12,127. However, the new HDD only power on 137hours. (About 1 week of my use.) The data below is my new HDD's SMART data (by EVEREST 5.50):
ID
01   Raw Read Error Rate   62   100   100   0

C7   Ultra ATA CRC Error Rate   0   200   200   0

I'm pretty sure that the data is correct, because I can hear the HDD's Load / Unload sound very frequently. The C1 row increase about 2,000 per day. However my previous Hitachi 5K320 has no problem. The running operating system are both Windows 7.
I'm so worry about this. As you know, laptop HDD's L / UL Cycle is designed at 600,000. If my HDD continue increasing like this, it will reach this number in a very short time. Any one can help me?

It's a feature of modern 2.5" harddisks , the disk parks the head when its been inactive for a while, to avoid damage , uses less power , and reduces the heat etc gives the harddisk a better looking spec sheet , its meant to park its head after being inactive for a long time around an hour with proper management from the bios/os of the head parking feature, because there is nothing to manage this feature in hp's bios or os the disk parks the head about every minute for no reason then after 1 second the head goes back on the disk thats 1 load/unload cycle , it also effects performance as the head has to find its place back on the disk , load times will decrease by alot , videos will stutter the first few secs, i have the same problem but not as bad after 130 hours i had a count of around 1,250 load/unloads , different brands of disk have different idle timers plus i use utorrent which stops the harddisk from idling so much, there are a couple of solutions, you can find a tool to update/mod the harddisk firmware to increase the idle timer ( i decided against this as you can permently brake the harddrive and void the warrenty) , contact hp and request a bios update with proper management or the harddisk head parking feature i.e tell the harddisk it is idle after an hour, the temperary solutions are download hd tune and run it all the time this stops the harddisk from parking its head as it doesn't let it go idle , or the solution i am using at the moment download a programme called HDD scan , everytime you turn on/off you have to run the prog go to tasks/features/ide features set the advance power management from its default value to 254 then press set, no more unnessary load/unloads, downside is the disk runs a couple of 0c hotter mine still never goes above 40c even under full load thanks to a active cooling pad, also its less well protected against shock.

Load/Unload Component from Main Application

I want to load in my main application 2 components. At this moment I load them with this:
<components:loadProject id="loadPrj" visible="false" click="loadPrj_clickHandler(event)" verticalCenter="7" horizontalCenter="0"/>
and I only set visible to true. Inside this component there is a canvas.
But, is there any other way to do this using an AS class file? I would like to load/unload it on click, not only set true/false to visible.

For dynamic creation and destruction of objects, you want to use ActionScript.
So in your main app file, you might have a button that triggers a click handler that does this:
private function myClickHandler()void {
                var b1:CustomComponent = new CustomComponent();
                var b2:CustomComponent = new CustomComponent();
                /// Be sure to add them to the display list if they are visual components
                myPanel.addElement(b1);
                myPanel.addElement(b1);

I seem to get the "Loading" message a lot. Any Ideas?

Here recently it seems that I am getting the "Loading" message a lot when I want to view an image. This is even true for the "fit" view. When I try a 1:1 view, it seems to take forever to load. And this is in the Library module. Also, my computer seems to be running in the background constantly when I have LR open. I am running a PC with Windows XP. I have 2GB of RAM and a Pentium 4 processor (3.0 Ghz.)
Also, I have the following options set in LR:
standard size preview 1440 pixels
discard 1:1 after 30 days
automatically write changes to XMP
Also, when I import, I check the "render standard sized previews."
Thanks for any input!
Pat

The 'Write stuff to XMP' setting is a bad one to use at any time, in any version. If you need XMP files, my suggestion is that you manually command a metadata export at the end of your session, and then just let the computer work on the export while you do something else that isn't Lightroom. Just don't let it run on auto.
The biggest speedup that you can do is to work with a NEW catalog whenever possible, specially if you are doing sorting. If you need to integrate it into a central catalog later, just import it later. My previews went from taking an average of 8 seconds when I used a 1.2 catalog to almost nothing in a fresh 1.3 catalog.
The 'Create Previews during import' in 1.3 seeems to be somewhat broken under it's new design. I just imported 650 photos into a NEW catalog, and viewing them one after the other right after the import was taking several seconds. I think that it has to do with the previews being built AFTER the import is finished. So either wait it out, or better yet, if you want to see the progress, tell it to rebuild the previews manually. After that you will be able to see previews with zero delay.
Don't render 1:1 previews unless you will be actually looking at them. If you are just doing the initial sorting of photos, and you can check for detail later, wait until you have thrown out your garbage before manually commanding a 1:1 preview build.
After a long 'develop' session, go back to Library and manually tell LR to render the previews again, since they don't get uupdated during the develop phase.

Load & Unload Movie Issue

Hi Guys:
Have 2 unable solve issues, would be much appreciated if anyone could help.
// ISSUE 1 //
I am experiencing an issue with Load & Unload Movie. What happen is that I am trying to load an external SWF into a movie clip call movieContainer in my main website. This external SWF file has timeline that perform a animation when it's loaded into the movieContainer.
I can load and unload the movie with no problem...the issue is that after I unload the SWF and then at any point of the movie on the main website I click to load the SWF back to the stage.....the timeframe of the SWF file stay at where it get left off(when it's unloaded). I am trying to make it play start all over again.
I try the movieContainer.content.gotoAndPlay(1); but it doesn't do anything. Any idea how I could make this work?
Here is my code:
var content:Loader = new Loader();
content.load(new URLRequest("externalSwf/content.swf"));
loadMovieButton.addEventListener(MouseEvent.CLICK, loadMovieButtonClicked);
function loadMovieButtonClicked(e:MouseEvent):void{
    movieContainer.addChild(content);
// ISSUE 2 //
In my external SWF file, I have create a loading loader at the 1st frame. But it doesn't play all the time when I testing on the server. It works just fine when I test locally with TEST MOVIE. Not only it doesn't play all the time.....it suppose to play from 2nd frame of the movie after the loading is finished (I have a short animation play between frame 2 - frame 20) Instead of playing from frame 2 to frame 20, the animation just jump straight to frame 20...which mean the user won't see the animation between frame 2 - frame 20.
import flash.events.ProgressEvent;
function update(e:ProgressEvent):void
var percent:Number = Math.floor( (e.bytesLoaded*100)/e.bytesTotal );
if(preloaderMC is MovieClip){
preloaderMC.gotoAndStop(percent);
//preload_txt.text = String(percent);
if(percent == 100){
gotoAndPlay(2);
loaderInfo.addEventListener(ProgressEvent.PROGRESS, update);
// Extra test for IE
var percent:Number = Math.floor( (this.loaderInfo.bytesLoaded*100)/this.loaderInfo.bytesTotal );
if(percent == 100){
nextFrame();
stop();
Many Thanks!

Thanks for the reply, the code I use to load the external SWF is:
The button is within a movieClip: commercialScrollBar_mc
The button instance name is: stackPancakeBar
The external SWF get to load into a movieClip container call: projectDetailsContainer_mc
var ldr:Loader = new Loader();
ldr.load(new URLRequest("projectsCommercial/stackPancakeBar.swf"));
commercialScrollBar_mc.stackPancakeBar.addEventListener(MouseEvent.CLICK, stackPancakeBarClicked);
function stackPancakeBarClicked(e:MouseEvent):void{
    MovieClip(ldr.content).gotoAndPlay(1);
    projectDetailsContainer_mc.addChild(ldr);
I was thinking does it has anything to do with the UNLOAD script I have on the external SWF file? Below are the code for removing the child.
back_btn.addEventListener(MouseEvent.CLICK, removeProjectDetails);
function removeProjectDetails(e:MouseEvent):void{
    this.parent.parent.removeChild(this.parent);
Thanks Heaps, by the way, do you have any idea why the loading sequence doesn't get to play every time? Or perhape the file size is too small?

RSRV Load/Unload of indexes

Not important topic, but may be someone from SAP will be interested with this observation.
Loading and unloading (i.e. deleting) from memory of the huuuge single BIA index with RSRV I noticed incremental increase of memory consumption on the blade where this index is assigned. After couple of repetitive loads/unloads I incresed memory consumption from 6GB to 13GB. (Then I decided to stop, otherwise I would might crash my 16GB blade).

Hi Satyam,
It was an issue with memory leak in that Revision of BWA. Current revisions (like 50+) are much-much better with that.

Very high HDD load/unload cycles and hardware ECC (SMART)

Hello,
I just took a look at my Seagate HDDs SMART values and found 2 very high numbers:
Load/Unload Cycle Count: 29.422, and increasing +1 like every 15 seconds, together with a clunking noise.
Hardware ECC Recovered: 320.239.221, and increasing +10 or more like every second.
The Load/Unload stuff seems to be aggressive power management of either the drive itself or the OS, I have no clue how to stop this. I tried keeping the drive busy with declunk, but it still parks the heads every few seconds.
But what is Hardware ECC ? And can anyone give me an advice on how to stop my drive moving the heads to the parking position every 15 seconds ? When I used Tiger, opening Photo Booth did the trick, doesn't work on Leopard tho. The HDD is less than 1 month old...

I too was getting so annoyed by the clunking sounds. The APM settings for the HDD are obviously out of whack completely. Tried Declunk which has been mentioned in other threads in the forums. It basically runs as a daemon making a small file and then deleting it every 5 seconds. I got it to work, but I had to introduce an additional parameter string to force it to create the file every 4 seconds. Visit http://kiza.kcore.de/software/declunk/ for more information on this issue.
Overall, I was still unhappy with the solution. Creating a file ever few seconds isn't optimal.
Having tested disabling the APM settings with hdparm for WinXP (Via Bootcamp) and found that it fixed the clunking sound, I knew that APM was definitely causing the sound. Of course, hdparm did not update the firmware of the hdd, so every time I powered down my MBP, the hdd would go back to APM being on "FULL" bringing
back the "clunk" sound.
The ideal solution was to obtain some kind of APM management software for OSX. Unfortunately, the historical application known as APM Tuner X was no longer being developed by the author and does not run in Leopard.
Thats when I found HDAPM!!!
http://mckinlay.net.nz/hdapm/
How did you determine the load/unload cycles for your HDD? In the end I located a copy of smartmon for Windows and booted into WinXp (via Bootcamp). I think my cycles are up to over 100,000... Not sure how to easily tell?!
Anyway, I hope that this solves your issue. Apple's Energy Saving system preference pane SHOULD disable putting the hard disk to sleep if left unchecked, but I also believe this is an issue with many HDD's. Seagate are shocking when it comes to releasing firmware upgrades too by the looks of things.

T400s Hard Drive Clicking - Load/unload cycle count SMART Attribute decreasing very quickly

Hi,
I get a T400s 2808 CVG. I degrade to XP Pro SP3.
The Hard-drive is Toshiba MK2529CSG.
I experience Hardrive clicking (or ticking) when the hard drive is idle. Forcing the drive to be busy silences the ticking sound.
On the other hand I get the issue that "Load unload cycle count" SMART attribute is decreasing very quickly. I loose 1 point each 4 or 5 days.
I also make a little test to check the correlation between the reported number of load unload cycle count and the ticking sound.
Postive. Each time I hear the tick, each time the SMART attribute report one more Load/unload cycle count.
Any one get the same issue?
Any solution?
I already see and read http://www.thinkwiki.org/wiki/Problem_with_hard_drive_clicking
Thanks and regards,
Patrick

any harddisk that make any unusual mechanical noises probably means the the harddisk will die soon

How to use Load XML Data (Home Utilities Data Load/Unload Load)

How is Load XML Data (Home>Utilities>Data Load/Unload>Load) supposed to work? Where is this documented?
What table type/structure is required?
How does this related to XDB functionality?

It's not really documented that well in the XE redux documents (or even the base Apex Documents)- see http://download-west.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/sql_utl.htm#sthref2530
However, it's reasonably easy to use - you can export a table to XML format, and then reload the table with the data by importing the XML document. It has nothing to do with XDB, it's just a different flat file representation for unloaded data than CSV

Diff. times are taken to complete load unload archive and unarchive

Hi All,
I am facing a problem with loading unloading archiving and unarchiving repository.
Problem is Everyday it is taking different to complete the process. Is the time deneds on the data and images availavle in the repository?
If large amount of data is there then it will take more time to complete all these process or large amount of user are log in it will take more time to unload?
Please Suggest
Thanks

Hi Shalini,
The repository Archieving and Unarchieving operations involves the data base.
I mean Repository tables and fields and the data of the repository are in the underlying database and You can backup an MDM repository using the MDM archiving mechanism.That will save the repository scema .a2a file for furthere refrence.This schema contains the tables and fields inside the tables and all these things are storesd on the DBMS level.So suppose next time when you unarchieve the repository and made some changes like
1.You have added some new Tables and Fields.
2.You have added new Data.
And all this is getting stored at the database leve at the end.
In this case the amount of data of your repository in terms of Tables and Fields or Data at the DBMS Level.So next time when you take archieve of your Repository It will take some extra time as compare to the previous one.And same thing will happen in case of Unarchieving because this time some new tables and their fields and some new data(images,pdfs etc) they all will be unarchieved as a Part of Repository so it will take a bit extra time to Unarchieve.
Same thing will happen in case of Loading and Unloading as the tables ,fields and amount of data increases the time to load and unload will also increases.
At the time of loading the repository You can go to your MDM Server and check that repository in status it will show checking image ID's ,processing tables,processing sound tables,loading search indexes etc.
Making a few minor adjustment with MDM and/or the DBMS server can enhance search and update performance by 10% to 20%.
SQL Serveru2019s performance increases by about 10% when the main data file (.mdf) and the transaction log file (.ldf) are located on separate spindles. Remember that this means using different drives, not just
different drive letters.

I have 3 different sets of actionscripts for load/unload.
But, the problem is when I click vita or other menu on the
top after loading "main" external .swf, they are overlapped.
How can I unload the external .swf from the automatically
loaded .swf?
(As I know, there are mostly buttons to click on loading
external .swf. But for my design, I want it loads automatically.)
Thanks in advance for suggestions. Please let me know if my
description/question is not clear to answer.

Are you using AS2 or AS3. The approach is completely
different for both.

How to Load/Unload external SWF

Hey all, I'm in a desperate struggle to meet a deadline for college coursework. I am unable to UNLOAD an external SWF file that I have put inside another SWF file. The problem that is occurring is, although it loads successfully, when I attempt to navigate to another page after viewing the external SWF, I expect it to close as it goes on to another page however, it remains in place. If i then go back on to the page that it is loading from, it will start to keep adding more and more SWF's. The print screens should explain it easier... Below i'll post the code that I'm using currently. The external SWF I am trying to load/unload is an interactive hangman game (whether it being interactive has an effect I do not know), but any and all help with this would be seriously appreciated!
The code currently being used is:
var _swfLoader:Loader;
var _swfContent:MovieClip;
loadSWF("Real Hangman.swf");
function loadSWF(path:String):void {
   var _req:URLRequest = new URLRequest();
   _req.url = path;
   _swfLoader = new Loader();
   setupListeners(_swfLoader.contentLoaderInfo);
   _swfLoader.load(_req);
function setupListeners(dispatcher:IEventDispatcher):void {
   dispatcher.addEventListener(Event.COMPLETE, addSWF);
   dispatcher.addEventListener(ProgressEvent.PROGRESS, preloadSWF);
function preloadSWF(event:ProgressEvent):void {
   var _perc:int = (event.bytesLoaded / event.bytesTotal) * 100;
   // swfPreloader.percentTF.text = _perc + "%";
function addSWF(event:Event):void {
   event.target.removeEventListener(Event.COMPLETE, addSWF);
   event.target.removeEventListener(ProgressEvent.PROGRESS, preloadSWF);
   _swfContent = event.target.content;
   _swfContent.addEventListener("close", unloadSWF);
   addChild(_swfContent);
function unloadSWF(event:Event):void {
   _swfLoader.unloadAndStop();
removeChild(_swfContent);
   _swfContent = null;
This printscreen is showing what it looks like in the Flash view (plain background and external SWF loads when this SWF is published)
What it looks like when loaded as published swf
Picture of the external SWF working inside the other SWF
Picture of it not being able to unload when i navigate to another page!
Finally, a picture of it doubling up when i proceed to go on the 'game' page again, it just keeps loading the SWF's rather than unloading them!

for example, file1 consits of two buttons, and also considered as main page. As i click on these two buttons , it will lead me go to open the external file2.swf, and file3.swf respectively. (file2.swf and file3.swf could have other navigation buttons, however, i am just simplify here).
the code you provided is working fine. but i want to totally remove/unlink the orginal file (file1.swf) when i click on either buttons which could lead me to other page (file1.swf or file2.swf).
Besides that, in file2.swf and file3.swf could have another "back" button to turn it back to the main page (file1.swf). When the user click on that back button, the file2.swf will unloaded...and file1.swf will be called back again...
can it be done?
so sorry if my poor explanation makes you confuse..
thank you.

Load / unload a lot...
