Multipal image or xml loading at a time or one By one

Hello friends,
                  I am confuse About multipal image loading at a time or one By one . it may crass DueTo memory problem.
                  which one is better and why.
                  plaase help me.
                 thanks.

Thanks,
             But actual prblem is if I load lots of Images At a time By for loop. Is ther any possibility to crass Due to memory problem ?.
              for understanding :-
               assume ther is a function which load image named "loadImg()" taking parameter Path of the image.
               NOW I am going to call function To load many more images at a time.
               var pathArr:Array = new Array("path","path","path","path","path","path","path","path","path","path","path","path" ,"path","path","path","path","path","path","path","path","path","path","path","path")
for(var i:uin = 0; i<pathArr.length; i++)
          loadImg(pathArr[i])
In this case all images going to load togather No of images depending on pathArr.length. In this case can crass .
OR,
I have to wait till complete loading of this image then can go to another image loading.

Image from database loaded at run time.

Post Author: Adam20002
CA Forum: .NET
I am using Crystal Reports 11. I have a report with an image in it that i want to change dynamically from my ASP.Net page. I am doing this at the moment by passing an image path in as a parameter and setting the Graphics Location property. However the requirement has changed and now the image is coming from a database. So if i wanted the user to be able to select from a list of images stored in the database and have that image appear in the report when it is loaded what would be the best way to go about it?
Thanks

Did you ever find a solution to this problem? I have the same problem when moving reports from development to Test to Production environments. If the DBName is not the same the report ignores the name provided at runtime.

Website images will sometimes load and other times I get the blue square?

Does anyone know how to resolve the following:
frequently visited websites will load images and then while searching the website (i.e. vrbo.com) the images will no longer appear and I'll see the blue square and "?". Why does this happen and how can I change this?

HI,
If you are using Safari, from the menu bar click Safari / Preferences then select the Appearance tab.
Select the box next to: Display images when the page opens
You may need to Quit Safari then restart in order for the changes to take effect.

How to load images using xml in flash

Hi
im working on a quiz project where i plan to load images using xml in to flash, can any one help with the script with AS2 or 3

Pre-loading external images for XML-based gallery

I'm working-on an XML-based photo gallery here:
http://www.unionandparkwood.com/demo/flash_gallery/
It works how I want it, except that the first time a
thumbnail is clicked for an image, it pauses long enough to skip
the fade. If you click-through the images a second time, you'll see
that it works smoothly. My guess is that the first time the
thumbnail is clicked, the image isn't cached, yet.
I tried to fix this by creating a JavaScript file for the
page to pre-load each image and thumbnail:
0003a = new Image;
0003a.src = "images/Down-Range.jpg";
0003b = new Image;
0003b.src = "thumbnails/Down-Range.jpg";
But that didn't work. What would be the best way to do this?
I included a link to "Download ZIP" of the FLA project on
this page, too, because it wouldn't be easy for me to describe
what's happening. In a nutshell, a thumbnail click launches a
function that loads the appropriate image into the main image
holder. What seems to be happening the first time is the image
isn't loaded before the fade is finished, so the image just appears
after a short pause the first time.

>>What seems to be happening the first time is the

As has been said many times in thos forum - use the
MovieClipLoader class to
load images, and then use that class' onLoadInit method to do
things with
the loaded image. Loading is asynchronous - you _have_ to
wait until the
image is done loading before doing a fade.

Swapping xml loaded Images to scene elements?

Hi there!
I have a small quick question about xml loaded images.
Can you append/attach/swap the images to elements in your scene?
I would like to manually animate a movieclip using keyframes and motion tweens. For example, to have a movieclip FLY! accross the screen! lol But I want the image on it to be of one that has been dynamically loaded.
I can't seem to work out how to replace an image on a movieclip from a dynamically loaded image.
Is it even possible?
Thanks heaps for your time you guys!

If the original image is the only object within the movieclip, you can use removeChildAt(0) to get rid of it, and use addChild(your_new_image) to replace it.

Images loaded at run time

I have a situation where I need to have images placed on a web page, but the images themselves will be loaded from a database.
How to I place these images that I load (jpg files) into the page?
It looks like the Image component is only set up to bind to static fields at design time.
Note that I can store off the image as anything I need to. I just need a way to display the image in somehting that Java Studio Creator gives us!
Thanks.

Hi,
Please go through the following thread:
http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=46410
It has a discussion and code samples on how to display images from database tables.
I hope this is helps you.

How do i load an image through XML?

Hi.
My code is below. What I am trying is to dinamically load images from xml. I attach the holder from the library, and when i try to target it and addChild to him i get an error:
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
xmlLoader.load(new URLRequest("links.xml"));
var xmlLength:int;
var iconPos:Number = 0;
function LoadXML(e:Event):void {
xmlData = new XML(e.target.data);
var xmlLength = xmlData.link.length();
for (var i=0; i<xmlLength; i++) {
var d:MovieClip = new icon();
content_mc.addChild(d);
d.name = "d"+i;
var target:DisplayObject = content_mc.getChildByName("d"+i);
var ldr:Loader = new Loader();
ldr.load(new URLRequest(xmlData.link[i].icon));
target.addChild(ldr);
How can i make this happen and load the image into it's holder?
Thank you.

Load hyperlink into image from xml

Hello everyone,
I am completely new to Flex and got stuck with this problem:
I would like to put a hyperlink into an image, both are loaded from external xml
xml looks like this:
      <project>
      <id>0</id>
      <titel>project google</titel>
      <image>image1.gif</image>
      <url>www.google.com</url>
      <date>06/01/2008</date>
      <description>Some description</description>
    </project>
So the url needs to be put into image 1
Hope someone can help me out...
Thanks in advance!

how is the XML loaded in? via PHP? or a static XML file.
if it's a static XML file, you'll have to load it in, feed it to an XML List collection and then simply feed the correct node to the image source.
they do this kind of thing here:
http://blog.flexexamples.com/2008/03/08/creating-a-simple-image-gallery-with-the-flex-tile list-control/
if it's loaded in via PHP, you'll need to handle the HTTPService request, and feed the image source an item off the result event.

Images not loading at run-time

See website uaesocial.joolo.com
The images are not loading... I've verified the path. The
images show when I'm working on the project offline but when I
upload it, it doesn't show... path is on the same domain, e.g.
assets/pictures/pic1.jpg
I tried using SWFLoader instead of Image and it still won't
work.
Any ideas?!

have you tried changing your links and putting the images in
the same directory as your flex file. as this maybe the
flash-players sandbox issue.

Images in XML Form

Hi Guys,
Need some help here. I want to set a fix image in my renderlistitem view. I have store the images in a folder in KM and have place the file path at the 'image url' of the form. Unfortunately, when i try to disply in the portal, i got a blank image with a small 'x' with caption 'show this image'. What am i doing wrong here? Thanks

HI
while navigating in ur xml to fix the location of image could u able to have a thumbnail image in the selection screen ?
it could that generation of thumbnail will be terminated automatically after 60 sec after this time u will find image with default x mark.
try with image of low size ,as this could be one solution if i am predicting the problem correctly
u may need to need to configure it in thumbnail plugins if u want ur high quality image to be loaded.

XML load error - when moving table data after upgrade

Greetings:
Background:
Previously in our 2.2 instance, we would use the Data Load/Unload feature of APEX to move data in the form of XML from instance 1 to instance 2. This woks well because it moves images also (BLOB)
What Changed:
Recently we did the upgrade to APEX 3.0. The tool is working well, but we are having issues uploading XML data in the same manner we used to. The process wizard works up until time for execution.. the following error message is seen.
XML load error.
Return to application.
Assumption:
I do not believe this is an XML file issues because the file I am testing the process with is from the EMP table, and is from the UNLOAD option on the same DB and SCHEMA.. (testing is unloading the data, than re-loading the same data to the same place)
Internally some permissions or something internal must be missing.
Assistance or suggestions on where to look is greatly appreciated.
Regards,
Tim

Tim,
Sorry for the delay - that silly day job keeps getting in the way.
Here is a small procedure you could use to take the XML data file format exported from Application Express and import into your table. This uses the Java-dependent DBMS_XMLSAVE package, which avoids the issue mentioned above.
create or replace procedure load_xml(
    p_clob   in clob,
    p_schema in varchar2,
    p_table in varchar2 )
is
    l_insCtx dbms_xmlsave.ctxType;
    l_rows   number;
begin
    l_insCtx := dbms_xmlsave.newContext(p_schema || '.' || p_table);
    dbms_xmlsave.setDateFormat(l_insCtx,'yyyy-MM-dd''T''HH:mm:ss.SSS');
    l_rows := dbms_xmlsave.insertXML( l_insCtx, p_clob);
    dbms_xmlsave.closeContext(l_insCtx);
end load_xml;I then ran the following quick test on apex.oracle.com just for verification.
declare
    l_xml varchar2(32000);
begin
    l_xml := '<?xml version="1.0"?>
<ROWSET>
<ROW>
<ID>11645117496276327</ID>
<FLOW_ID>30072</FLOW_ID>
<NAME>F11645117496276327/no_image_found.gif</NAME>
<FILENAME>no_image_found.gif</FILENAME>
<MIME_TYPE>image/gif</MIME_TYPE>
<CREATED_BY>JOEL</CREATED_BY>
<CREATED_ON>2007-03-14T05:06:38.000</CREATED_ON>
<BLOB_CONTENT>474946383961C800...(data removed for this example)...41000003B</BLOB_CONTENT>
</ROW>
</ROWSET>';
    load_xml( l_xml, 'MY_DB_USER', 'MY_APEX_FILES' );
end;It's now simply a matter of how you get your XML file(s) into a CLOB to call this procedure. The options include:
1) Just pass in a VARCHAR2 as I did in the example above, which would limit you to roughly 32K.
2) You could use DBMS_LOB.LOADCLOBFROMFILE to read it from the database server filesystem.
3) You could upload the file via an APEX application (or some other means within APEX), you could convert the BLOB to a CLOB, and then call this procedure. If you need help with this method, let me know.
Don't forget - as yet another alternative, you could always contact Oracle Support to see what could be done about that underlying database bug.
I hope this helps.

How do I script SWF files instead of JPG files in XML loader?

I have a SWF loader (greensock.com platform) and a thumbnail image scroll underneath it made of small image buttons. Each image button has a link which loads a new SWF file into the SWF loader above. Here is the code for each button which loads the bigger SWF file into the loader above:
Button3.addEventListener(MouseEvent.CLICK, Button3_PlayPopUp);
function Button3_PlayPopUp(event:MouseEvent): void {
    //setting the sourceVar
    sourceVar="3.swf";
    //making the SWFLoader load
    //as setting the soureVar after the SWFLoader is created won't do anything unlesss
    //I also re-create the SWFLoader with the new sourceVar when the button is clicked
    loader_howToLoader2.url = sourceVar;
    loader_howToLoader2.load(true);
Then I decided to load all button via XML loader. I followed the tutorial on XML loaders which deals with loading jpg images and assigning URL links to them in the following manner first in XML file:
<image src="appThmb_imgs/appThmb_imgs117x175/A-illuminatorUpLit_117x175.jpg" title="UpDownGlowingVase" url="http://www.888acolyte.com"/>
and then in AS3 like this:
var xmlLoader:URLLoader = new URLLoader();
thisOne.link = imageList[item].attribute("url");
function clickScrollerItem(e:MouseEvent):void {
//trace("clicked item " + e.currentTarget.itemNum + " - visit url: " + e.currentTarget.link);
var urlRequest:URLRequest = new URLRequest(e.currentTarget.link);
try {
navigateToURL(urlRequest);
catch (e:Error) {
// handle error here
trace(e);
My question is: How do I apply the code to each individual small thumbnail button to load a bigger image into the SWF loader above? Do I have to add something to XML file or this way it will never work with jpg images? Can url in XML file set the source var (//setting the sourceVar), since they are all individual and then somehow apply the making SWL loader to load part (//making the SWFLoader load) as a standard somewhere in the AS3 code?

O.K. Here is my COMPLETE function.
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
function LoadXML(e:Event):void {
    trace("xml load complete");
    xmlData = new XML(e.target.data);
    //trace(xmlData.image); //we'll see each image xml element listed in the output panel with this xmlList
    buildScroller(xmlData.image); //rather than trace the xmlList, we send it to our buildScroller function
//build scroller from xml
function buildScroller(imageList:XMLList):void{
    trace("build Scroller");
    //var scroller_x:int=0;
    for (var item:uint = 0; item<imageList.length();item++) {
        var thisOne:MovieClip = new MovieClip();
        //thisOne.img_width=imageList[item].attribute("width");
        //outline
        var blackBox:Sprite = new Sprite();
        blackBox.graphics.beginFill(0xFFFFFF);
        blackBox.graphics.drawRect(-1, -1, 86, 128);//-1,-1 places rectangle 1px left and up.86, 128 draws rectangle 1px wider on all sides of placed image dimenstions of 84x126
        thisOne.addChild(blackBox);
        //scroller_x += thisOne.img_width + 20;
        //var currentX = currentImageWidth+spaceBetween;//modified line to adjust variable thumb widths
        thisOne.x = (84 + padding) *item;//84 is the width of the loaded images and 15 (which was before paddign var) is the padding
        //thisOne.x = scroller_x;//modified line to adjust variable thumb widths
        thisOne.itemNum = item;
        thisOne.title = imageList[item].attribute("title");
        thisOne.link = imageList[item].attribute("url");
        thisOne.src = imageList[item].attribute("src");
        thisOne.alpha = 0;//makes all thumb images at alpha=0 before they are fully loaded
        //trace(thisOne.itemNum, thisOne.title, thisOne.link, thisOne.src);
        //Loading and Adding the Images
        //image container
        var thisThumb:MovieClip = new MovieClip();
        //add image
        var ldr:Loader = new Loader();
        //var url:String = imageList[item].attribute("src");
        var urlReq:URLRequest = new URLRequest(thisOne.src);
        trace("loading thumbnail "+item+" into Scroller: " + thisOne.src);//url
        ldr.load(urlReq);
        //assign event listeners for Loader
        ldr.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);//tells us when the loading is complete
        ldr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);//tells us if there are any typo errors when the loading is complete
        thisThumb.addChild(ldr);
        thisOne.addChild(thisThumb);
        //create listeners for this thumb
        thisOne.buttonMode = true;//makes boxes act as buttons
        thisOne.addEventListener(MouseEvent.CLICK, clickScrollerItem);//makes boxes act as buttons
        thisOne.addEventListener(MouseEvent.MOUSE_OVER, overScrollerItem);//traces the title when the mouse is over the bounding box in the Output Panel
        thisOne.addEventListener(MouseEvent.MOUSE_OUT, outScrollerItem);//traces the title when the mouse is out the bounding box in the Output Panel
        //add item
        scroller.addChild(thisOne);
But I am not sure if I expressed myself clearly. All what you have indicated happens. Images are being loaded and url strings are working. I can not figure out how to tweek the code so instead of url specified in xml file I can load swf image into the SWF loader on the same screen?

Some images won't load in Safari, iTunes, iBooks and App Store

Since my upgrade to Mavericks, some images on Safari, iTunes, iBooks and App Store wont load some times. I can't figure out the source of problem, but I've tested all four apps and the same problem exists across all of them; I've also tested Chrome, Firefox and Opera to see if they are suffering from the same problem, and surprisingly enough I've found that they are not; They load images perfectly well, and I've never encountered one to not load images. I'm totally confused and frustrated, what is preventing Apple products to load images? Here are some screenshots:

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History and Web Site Data. The down side is it clears all cookies.Doing this may cause some sites to no longer recognize your computer as one that has visited the web site.

Image does not load in a new Form window

Hi everyone,
In Oracle Forms I have a Form with multiple windows. On startup only the main window is loaded. For some conditions during user input another window should be shown (I am using the SHOW_WINDOW functionality). In the new window is an Image which is set with the following code:
READ_IMAGE_FILE('image.gif', 'URL', 'IMAGE_PICTURE');
SHOW_WINDOW('DIALOG');
The image is stored in the JAR file and works for other form modules. But when I open the new window (Style = Dialog, Modal = Yes), the image is not loaded/displayed. But, if I close the dialog window and reopen it directly again the image is displayed.
Does someone know how to solve this issue? I would like to have the image displayed also the first time when the dialog window is opened.
Thanks!
Marco

I tried it right now, but without success.
In the new Window I only have the Image, a dynamically generated message for the user as an text item and a button (this sounds like I could use an alert box, but an alert box has some limitations which does not fit the user requirements). When I now try to set the "Synchronize with Item" property of the Image to one of the other items of the window, the Form cannot compile:
FRM-32084: Data Type of item is not compatible with mirror item MSG.
