• AS3 Pass FlashVars to loaded swf

  - by Robin

  Hi I have a A.swf which loads B.swf onto a movieclip and needs to pass it some FlashVars. When loading B.swf with html, I can pass FlashVars fine. When passing from A.swf, it gets a Error #2044: Unhandled ioError:. text=Error #2032: Stream Error. URL: file: The code in A.swf is var request:URLRequest = new URLRequest ("B.swf"); var variables : URLVariables = new URLVariables(); variables.xml = "test.xml"; // This line causes the error 2044, else B.swf loads fine with FlashVars request.data = variables; loader.load (request); In B.swf, it is checking the Flashvars like so. It works fine from html side this.loaderInfo.parameters.xml

• Jquery - dynamic DIV onclick binding

  - by Murtaza RC

  I have a main page from where I am making a call to "load" and intermediate page's HTML and on the completion of the load I am massaging the returned HTML to add a few DIVs etc, when I try to bind an onclick event for the dynamic Divs (added by me after the HTML returned from the intermediate page) it does not seem to work at all !: LOAD : $j(".loader").load(myURLtoIntermediatePage, '', function() { var HTML= '<div id="abcd">test</div>'; ... $j(".pageDIV").append(HTML); } DOCUMENT READY Function $j(document).ready(function() { $j('#abcd').onclick(function() { alert($j(this)); }); });

• Is there a way to convert a swf to an .abc file?

  - by Jeremy Ruppel

  I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

• Map Custom URL protocol to HTTP (using NSURLProtocol?)

  - by Francisco Ryan Tolmasky I

  I have an application using a WebKit WebView and I'd like to map URL's that are loaded in this WebView with a custom URL protocol to a different HTTP URL. For example, say I am loading: custom://path/to/resource I would like to internally actually load: http://something-else.com/path/to/resource In other words, the custom protocol serves almost as a shorthand. I can't however use -webView:resource:willSendRequest:redirectResponse:fromDataSource:, because I want WebKit to actually believe this is the URL in question, not to simply redirect from one to the other. So far I've been attempting to use a custom NSURLProtocol subclass. However, this is proving trickier than I first thought because, at least to my understanding, I will have to do the actual loading myself in the NSURLProtocol subclass' startLoading method. I'd like a way to just hand off the work to the existing HTTP protocol loader, but I can't find an easy way to do this. Does anyone have a recommendation for this, or perhaps an alternative way to solve this issue? Thanks!

• How do I convert CamelCase into human-readable names in Java?

  - by Frederik

  I'd like to write a method that converts CamelCase into a human-readable name. Here's the test case: public void testSplitCamelCase() { assertEquals("lowercase", splitCamelCase("lowercase")); assertEquals("Class", splitCamelCase("Class")); assertEquals("My Class", splitCamelCase("MyClass")); assertEquals("HTML", splitCamelCase("HTML")); assertEquals("PDF Loader", splitCamelCase("PDFLoader")); assertEquals("A String", splitCamelCase("AString")); assertEquals("Simple XML Parser", splitCamelCase("SimpleXMLParser")); assertEquals("GL 11 Version", splitCamelCase("GL11Version")); }

• actionscript 3.0 garbage collection with casalib ?

  - by algro

  I would love to see an actual example how to use the casalib-garbage-collection. I used the destroy method like in the description: casa-lib description If I have a Loader in a Subclass, do I also have to use the CasaLibLoader? Do I have still to care about all Instances/Eventlisteners to do proper garbage collection? If yes, whats the advantage of casalib-garbage-collection? I assumed to call destroy on a Casalib-Sprite and then it would destroy all its subclasses and references, and therefore safe memory. It would be awesome to get an easy instruction. Thanks in advance

• How to load object after saving with encodeWithCoder?

  - by fuzzygoat

  EDIT_002: Further rewrite: if I save using the method below how would the method to load it back in look? (moons is an NSMutableArray of NSNumbers) // ------------------------------------------------------------------- ** // METHOD_002 // ------------------------------------------------------------------- ** -(void)saveMoons:(NSString *)savePath { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [moons encodeWithCoder:archiver]; [archiver finishEncoding]; [data writeToFile:savePath atomically:YES]; [archiver release]; [data release]; } EDIT_003: Found it, my problem was that I was using ... [moons encodeWithCoder:archiver]; where I should have been using ... [archiver encodeObject:moons]; Hence the loader would look like: -(void)loadMoons_V3:(NSString *)loadPath { NSData *data = [[NSData alloc] initWithContentsOfFile:loadPath]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [self setMoons:[unarchiver decodeObject]]; [unarchiver finishDecoding]; [unarchiver release]; [data release]; } gary

• Grails Illegel Exception

  - by Srinath

  Hi, Can any one tell me when this error occurs . I suspect this is coming when added any new js in Grails . I'm unable to dig this : 16 Apr, 2010 4:58:25 PM org.apache.catalina.loader.WebappClassLoader loadClass INFO: Illegal access: this web application instance has been stopped already. Could not load org.codehaus.groovy.grails.plugins.codecs.HTMLCodecBeanInfo. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact. java.lang.IllegalStateException thanks in advance, srinath

• Deep Null checking, is there a better way?

  - by Mattias Konradsson

  We've all been there, we have some deep property like cake.frosting.berries.loader that we need to check if it's null so there's no exception. The way to do is is to use a short-circuiting if statement if (cake != null && cake.frosting != null && cake.frosting.berries != null) ... This strikes me however as not very elegant, there should perhaps be an easier way to check the entire chain and see if it comes up against a null variable/property. So is it possible using some extension method or would it be a language feature, or is it just a bad idea?

• Using Hibernate with Dynamic Eclipse Plug-ins

  - by AlbertoPL

  I have classes that are named exactly the same across different plug-ins that I use for my application, and I'd like to be able to configure them properly with Hibernate. The problem is that it looks like Hibernate dynamically generates a class' package name when trying to find a class when it's doing its mapping. With one plug-in this scheme works, but across multiple plug-ins it's not working. It looks like Hibernate gets confused when dealing with Hibernate configuration files across multiple plug-ins. Is this because each plug-in has its own class-loader? What is the best way to proceed to make this work with the existing plug-ins and Hibernate?

• QML 5.3 iOS compilation of pure QML app

  - by Nathaniel Johnson

  I have an application written in QML. Initially, I used the standard C++ bootstrap for the app. int main(int argc, char *argv[]) { QApplication app(argc, argv); // A bunch of components and data models written in C++ QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:///main.qml"))); return app.exec(); } The bulk of the app is in QML and the more I work with QML, the happier I am with it and the more I feel comfortable converting the C++ pieces to QML. So, it comes to one risk that I wanted to ask about. If I convert the app to a pure QML application like the kind generated by the Qt Quick UI application wizard with no C++ and designed to be run with qmlscene will I be able to compile it for iOS when the time to port it comes or will I end up just converting it back to the C++ loader form? TL;DR Can pure QML (no C++) apps be compiled and run on iOS devices?

• Problem with launching JAGUAR in R

  - by Gerry

  Windows XP, R 2.11.1, Java JRE6 I just installed the Jaguar package. From an R console, I can do this: > library(JGR) Loading required package: rJava Loading required package: JavaGD Loading required package: iplots Please use the corresponding JGR launcher to start JGR. Run JGR() for details. You can also use JGR(update=TRUE) to update JGR. and so JGR appears to be correctly installed. JGR() yields On Windows JGR must be started using the JGR.exe launcher. Please visit http://www.rosuda.org/JGR/ to download it. > I'm not sure how to run Jaguar - I know I have to run jgr.exe - but should R be already open? If so, should the JGR library be already loaded? I've tried all of these, and what seems to happen regardless is a console window opens briefly, then disappears. I've run jrg --debug, with no apparent error message: (same file regardless of choice made above). What should I be doing? Thanks!

• PIG doesn't read my custom InputFormat

  - by Simon Guo

  I have a custom MyInputFormat that suppose to deal with record boundary problem for multi-lined inputs. But when I put the MyInputFormat into my UDF load function. As follow: public class EccUDFLogLoader extends LoadFunc { @Override public InputFormat getInputFormat() { System.out.println("I am in getInputFormat function"); return new MyInputFormat(); } } public class MyInputFormat extends TextInputFormat { public RecordReader createRecordReader(InputSplit inputSplit, JobConf jobConf) throws IOException { System.out.prinln("I am in createRecordReader"); //MyRecordReader suppose to handle record boundary return new MyRecordReader((FileSplit)inputSplit, jobConf); } } For each mapper, it print out I am in getInputFormat function but not I am in createRecordReader. I am wondering if anyone can provide a hint on how to hoop up my costome MyInputFormat to PIG's UDF loader? Much Thanks. I am using PIG on Amazon EMR.

• OpenGL: small black pixel on top right corner of texture

  - by user308226

  I wrote an uncompressed TGA texture loader and it works nearly perfect, except for the fact that there's just one TINY little black patch on the upper right and it's driving me mad. I can get rid of it by using a texture border, but somehow I think that's not the practical solution. Has anyone encountered this kind of problem before and knows -generally- what's going wrong when something like this happens, or should I post the image-loading function code? Here's a picture, the little black dot is REALLY small. http://img651.imageshack.us/img651/2230/dasdwx.png

• xml and external swf documents

  - by VideoDnd

  My XML scripts work fine in the local swf. If I load an external swf, can I still retreive XML data from the same way, or do I have to declare the root somewhere? It's a general question. I know that when animating external swf files, you have to set it up differently, if so I would like an example, and a pitcher of beer. It's St. Patrick's weekend. SAMPLE CODE ONLY XML <?xml version="1.0" encoding="utf-8"?> <SESSION> <COUNT TITLE="starting position">-77777</COUNT> </SESSION> loader swf 'nodes' //grab the data as a string myString = myXML.COUNT.text(); //grab the data as an int count = int(myXML.COUNT.text()); external swf 'variables' var myString:String = ""; var count:int = int(myString); trace(count);

The concept works, but I'm stuck on how to pass context to my renderer. Here's what I have so far: from django.shortcuts import render_to_response from django.http import HttpResponse from django.template.loader import render_to_string def raw_response(template): def wrap(view): def response(request,*args,**kwargs): if request.method == "GET": try: if request.GET['raw'] == "1": render = HttpResponse(render_to_string(template,{}),content_type="text/plain") return render except Exception: render = render_to_response(template,{}) return render return response return wrap Currently, the {} is there just as a place holder. Ultimately, I'd like to be able to pass a dict like this: @raw_response('my_template_name.html') def view_name(request): render({"x":42}) Any assistance is appreciated.

• What are the typical reasons Javascript developed on Firefox fails on IE?

  - by karlthorwald

  I developed some javascript enhanced pages that run fine on recent Firefox and Safari. I missed to check in Internet Explorer, and now I find the pages don't work on IE 6 and 7 (so far). The scripts are somehow not executed, the pages show as if javascript wasn't there, although some javascript is executed. I am using own libraries with dom manipulation, from YUI 2 I use YUI-Loader and the XML-Http-Request, and on one page I use "psupload", which depends on JQuery. I am installing Microsoft Script Editor from Office XP and will now debug. I will also write specific tests now. What are the typical failing points of IE? What direction I can keep my eyes open. I found this page, which shows some differences: http://www.quirksmode.org/compatibility.html Can you from your experience name some typical things I should look for first? I will also ask more questions here for specific tasks later, but for now I am interested in your experience why IE usually fails on scripts that run fine in Firefox

• directx audio video error message in debugmode

  - by clamp

  I have a c#/winforms application that uses directx to play some video and audio. whenever i start my application in debugmode i get this annoying message. i can click "continue" and everything seems to work fine. but i still want to get rid of this message. it does not show up in releasemode. Managed Debugging Assistant 'LoaderLock' has detected a problem in 'C:\pathtoexe.exe'. Additional Information: DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX.AudioVideoPlayback\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.AudioVideoPlayback.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

• YUI Autocomplete: itemSelectEvent getting lost with IE6 and IE7?

  - by Parand

  I'm using YUI Autocomplete (latest version loaded using loader as of today (May 14th, 2010), which looks to be 2.8.1, with the following options: ac = new YAHOO.widget.AutoComplete("mynode", "autocomp_node", ac_ds, {typeAhead: true, forceSelection: true}); ac.itemSelectEvent.subscribe( function(type, args) { alert("hey:" + args[2][1]); $('#parent_id').val(args[2][1]); }); The itemSelectEvent catches selections in AutoComplete and fills in some data on the parent. This works on FF, Chrome, Safari, and IE8. On IE6 and IE7, however, the event never seems to trigger. To replicate: In the autocomplete field, allow it to autofill for you, then hit enter. This should select the autofill and move on to the next field (that's what it does in other browsers). With IE6 and IE7 it seems to instead trigger the form submission - the itemSelectEvent never fires (or perhaps fires after the form submission?). Has anyone seen this? Any work-arounds?

• Update table rows in a non-sequential way using the output of a php script

  - by moviemaniac

  Good evening everybody, this is my very first question and I hope I've done my search in stack's archive at best!!! I need to monitor several devices by querying theyr mysql database and gather some informations. Then these informations are presented to the operator in an html table. I have wrote a php script wich loads devices from a multidimensional array, loops through the array and gather data and create the table. The table structure is the following: <table id="monitoring" class="rt cf"> <thead class="cf"> <tr> <th>Device</th> <th>Company</th> <th>Data1</th> <th>Data2</th> <th>Data3</th> <th>Data4</th> <th>Data5</th> <th>Data6</th> <th>Data7</th> <th>Data8</th> <th>Data9</th> </tr> </thead> <tbody> <tr id="Device1"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> <tr id="Device2"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> <tr id="DeviceN"> <td>Devide 1 name</td> <td>xx</td> <td><img src="/path_to_images/ajax_loader.gif" width="24px" /></td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> <td>&nbsp;</td> </tr> </tbody> </table> The above table is directly populated when I first load the page; then, with a very simple function, i update this table every minute without reloading the page: <script> var auto_refresh = setInterval( function() { jQuery("#monitoring").load('/overview.php').fadeIn("slow"); var UpdateTime= new Date(); var StrUpdateTime; StrUpdateTime= ('0' + UpdateTime.getHours()).slice(-2) + ':' + ('0' + UpdateTime.getMinutes()).slice(-2) + ':' + ('0' + UpdateTime.getSeconds()).slice(-2); jQuery("#progress").text("Updated on: " + StrUpdateTime); }, 60000); </script> The above code runs in a wordpress environment. It comes out that when devices are too much and internet connection is not that fast, the script times out, even if i dramatically increase the timeout period. So it is impossible even to load the page the first time... Therefore I would like to change my code so that I can handle each row as a single entity, with its own refresh period. So when the user first loads the page, he sees n rows (one per device) with the ajax loader image... then an update cycle should start independently for each row, so that the user sees data gathered from each database... then ajax loader when the script is trying to retrieve data, then the gathered data once it has been collected or an error message stating that it is not possible to gather data since hour xx:yy:zz. So rows updating should be somewhat independent from the others, like if each row updating was a single closed process. So that rows updating is not done sequentially from the first row to the last. I hope I've sufficiently detailed my problem. Currently I feel like I am at a dead-end. Could someone please show me somewhere to start from?

• Incompatible classes when loading SWF

  - by Bart van Heukelom

  I have two ActionScript 3 projects, game(.swf) and minigame(.swf). At runtime the main game loads the minigame via Loader. I also have a shared library (SWC) of event classes, included by both, which minigame will need to dispatch and game will need to listen to. First: Is this possible this way? Second: What will happen if I compile the minigame, then change the event classes so they're incompatible, then compile the main game. Will Flash crash when trying to load the minigame SWF? (I hope so) Third: And what will happen if I change the event classes, but in a way that preserves interface-level compatibility?

• TextField breaking MOUSE_OVER in as3: only after moving it!

  - by Franz

  I'm having a really weird problem with the MOUSE_OVER event. I'm building dynamic tabs representing mp3 songs containing textfields with info and a dynamic image for the cover art. I am trying to get a simple MOUSE_OVER working over the whole tab, such that you can select the next song to play. I am using a Sprite with alpha 0 that overlays my whole tab (incl. the textFields) as a Listener for MOUSE_OVER and _OUT... I've checked by setting the alpha to something visible and it indeed covers my tab and follows it around as I move it (just making sure I'm not moving the tab without moving the hotspot). Also, I only create it once my cover art is loaded, ensuring that it will cover that too. Now, when the tab is in the top position, everything is dandy. As soon as I move the tab to make space for the next tab, the textFields break my roll behaviour... just like that noob mistake of overlaying a sprite over the one that you're listening for MouseEvents on. But... the roll area is still on top of the field, I've set selectable and mouseEnabled to false on the textFields... nothing. It is as if the mere fact of moving the whole tab now puts the textField on top of everything in my tab (whereas visually, it's still in its expected layer). I'm using pixel fonts but tried it with system fonts, same thing... at my wits end here. public function Tab(tune:Tune) { _tune = tune; mainSprite = new Sprite(); addChild(mainSprite); drawBorder(); createFormat(); placeArtist(); placeTitle(); placeAlbum(); coverArt(); } private function placeButton():void { _button = new Sprite(); _button.graphics.beginFill(0xFF000,0); _button.graphics.drawRect(0,0,229,40); _button.graphics.endFill(); _button.addEventListener(MouseEvent.MOUSE_OVER, mouseListener); _button.addEventListener(MouseEvent.MOUSE_OUT, mouseListener); _button.buttonMode = true; mainSprite.addChild(_button); } private function mouseListener(event:MouseEvent):void { switch(event.type){ case MouseEvent.MOUSE_OVER : hilite(true); break; case MouseEvent.MOUSE_OUT : hilite(false); break; } } private function createFormat():void { _format = new TextFormat(); _format.font = "FFF Neostandard"; _format.size = 8; _format.color = 0xFFFFFF; } private function placeArtist():void { var artist : TextField = new TextField(); artist.selectable = false; artist.defaultTextFormat = _format; artist.x = 41; artist.y = 3; artist.width = 135; artist.text = _tune.artist; artist.mouseEnabled = false; mainSprite.addChild(artist); } private function placeTitle():void { var title : TextField = new TextField(); title.selectable = false; title.defaultTextFormat = _format; title.x = 41; title.y = 14; title.width = 135; title.text = _tune.title; title.mouseEnabled = false; mainSprite.addChild(title); } private function placeAlbum():void { var album : TextField = new TextField(); album.selectable = false; album.defaultTextFormat = _format; album.x = 41; album.y = 25; album.width = 135; album.text = _tune.album; album.mouseEnabled = false; mainSprite.addChild(album); } private function drawBorder():void { _border = new Sprite(); _border.graphics.lineStyle(1, 0x545454); _border.graphics.drawRect (0,0,229,40); mainSprite.addChild(_border); } private function coverArt():void { _image = new Sprite(); var imageLoader : Loader = new Loader(); _loaderInfo = imageLoader.contentLoaderInfo; _loaderInfo.addEventListener(Event.COMPLETE, coverLoaded) var image:URLRequest = new URLRequest(_tune.coverArt); imageLoader.load(image); _image.x = 1.5; _image.y = 2; _image.addChild(imageLoader); } private function coverLoaded(event:Event):void { _loaderInfo.removeEventListener(Event.COMPLETE, coverLoaded); var scaling : Number = IMAGE_SIZE / _image.width; _image.scaleX = scaling; _image.scaleY = scaling; mainSprite.addChild (_image); placeButton(); } public function hilite(state:Boolean):void{ var col : ColorTransform = new ColorTransform(); if(state){ col.color = 0xFFFFFF; } else { col.color = 0x545454; } _border.transform.colorTransform = col; }
