  • Clickin issue in Flash and XML

    - by ortho
    Hi, I have the php backend that displays an xml page with data for flash consuming. Flash takes it and creates a textfields dynamicaly based on this information. I have a few items in menu on top and when I click one of them, data is taken from php and everything is displayed in scroll in flash. The problem is that if I click too fast between menu items, then I get buggy layout. The text (only the text) is becoming part of the layout and is displayed no metter what item in menu I am currently in and only refreshing the page helps. var myXML:XML = new XML(); myXML.ignoreWhite=true; myXML.load("/getBud1.php"); myXML.onLoad = function(success){ if (success){ var myNode = this.firstChild.childNodes; var myTxt:Array = Array(0); for (var i:Number = 0; i<myNode.length; i++) { myTxt[i] = "text"+i+"content"; createTextField(myTxt[i],i+1,65,3.5,150, 20); var pole = eval(myTxt[i]); pole.embedFonts = true; var styl:TextFormat = new TextFormat(); styl.font = "ArialFont"; pole.setNewTextFormat(styl); pole.text = String(myNode[i].childNodes[1].firstChild.nodeValue); pole.wordWrap = true; pole.autoSize = "left"; if(i > 0) { var a:Number = eval(myTxt[i-1])._height + eval(myTxt[i-1])._y + 3; pole._y = a; } attachMovie("kropka2", "test"+i+"th", i+1000); eval("test"+i+"th")._y = pole._y + 5; eval("test"+i+"th")._x = 52; } } } I tried to load the info and ceate text fields from top frame and then refer to correct place by instance names string e.g. budData.dataHolder.holder.createTextField , but then when I change between items in menu the text dissapears completely untill I refresh the page. Please help

  • Polymorphism problem: How to check type of derived class?

    - by malymato
    Hi, this is my first question here :) I know that I should not check for object type but instead use dynamic_cast, but that would not solve my problem. I have class called Extension and interfaces called IExtendable and IInitializable, IUpdatable, ILoadable, IDrawable (the last four are basicly the same). If Extension implements IExtendable interface, it can extend itself with different Extension objects. The problem is that I want to allow the Extension which implements IExtendable to extend only with Extension that implements the same interfaces as the original Extension. You probably don't unerstand that mess so I try to explain it with code: class IExtendable { public: IExtendable(void); void AddExtension(Extension*); void RemoveExtensionByID(unsigned int); vector<Extension*>* GetExtensionPtr(){return &extensions;}; private: vector<Extension*> extensions; }; class IUpdatable { public: IUpdatable(void); ~IUpdatable(void); virtual void Update(); }; class Extension { public: Extension(void); virtual ~Extension(void); void Enable(){enabled=true;}; void Disable(){enabled=false;}; unsigned int GetIndex(){return ID;}; private: bool enabled; unsigned int ID; static unsigned int _indexID; }; Now imagine the case that I create Extension like this: class MyExtension : public Extension, public IExtendable, public IUpdatable, public IDrawable { public: MyExtension(void); virtual ~MyExtension(void); virtual void AddExtension(Extension*); virtual void Update(); virtual void Draw(); }; And I want to allow this class to extend itself only with Extensions that implements the same interfaces (or less). For example I want it to be able to take Extension which implements IUpdatable; or both IUpdatable and IDrawable; but e.g. not Extension which implements ILoadable. I want to do this because when e.g. Update() will be called on some Extension which implements IExtendable and IUpdateable, it will be also called on these Extensions which extends this Extension. So when I'm adding some Extension to Extension which implements IExtendable and some of the IUpdatable, ILoadable... I'm forced to check if Extension that is going to be add implements these interfaces too. So In the IExtendable::AddExtension(Extension*) I would need to do something like this: void IExtendable::AddExtension(Extension* pEx) { bool ok = true; // check wheather this extension can take pEx // do this with every interface if ((*pEx is IUpdatable) && (*this is_not IUpdatable)) ok = false; if (ok) this->extensions.push_back(pEx); } But how? Any ideas what would be the best solution? I don't want to use dynamic_cast and see if it returns null... thanks

  • C++ destructor seems to be called 'early'

    - by suicideducky
    Please see the "edit" section for the updated information. Sorry for yet another C++ dtor question... However I can't seem to find one exactly like mine as all the others are assigning to STL containers (that will delete objects itself) whereas mine is to an array of pointers. So I have the following code fragment #include<iostream> class Block{ public: int x, y, z; int type; Block(){ x=1; y=2; z=3; type=-1; } }; template <class T> class Octree{ T* children[8]; public: ~Octree(){ for( int i=0; i<8; i++){ std::cout << "del:" << i << std::endl; delete children[i]; } } Octree(){ for( int i=0; i<8; i++ ) children[i] = new T; } // place newchild in array at [i] void set_child(int i, T* newchild){ children[i] = newchild; } // return child at [i] T* get_child(int i){ return children[i]; } // place newchild at [i] and return the old [i] T* swap_child(int i, T* newchild){ T* p = children[i]; children[i] = newchild; return p; } }; int main(){ Octree< Octree<Block> > here; std::cout << "nothing seems to have broken" << std::endl; } Looking through the output I notice that the destructor is being called many times before I think it should (as Octree is still in scope), the end of the output also shows: del:0 del:0 del:1 del:2 del:3 Process returned -1073741819 (0xC0000005) execution time : 1.685 s Press any key to continue. For some reason the destructor is going through the same point in the loop twice (0) and then dying. All of this occures before the "nothing seems to have gone wrong" line which I expected before any dtor was called. Thanks in advance :) EDIT The code I posted has some things removed that I thought were unnecessary but after copying and compiling the code I pasted I no longer get the error. What I removed was other integer attributes of the code. Here is the origional: #include<iostream> class Block{ public: int x, y, z; int type; Block(){ x=1; y=2; z=3; type=-1; } Block(int xx, int yy, int zz, int ty){ x=xx; y=yy; z=zz; type=ty; } Block(int xx, int yy, int zz){ x=xx; y=yy; z=zz; type=0; } }; template <class T> class Octree{ int x, y, z; int size; T* children[8]; public: ~Octree(){ for( int i=0; i<8; i++){ std::cout << "del:" << i << std::endl; delete children[i]; } } Octree(int xx, int yy, int zz, int size){ x=xx; y=yy; z=zz; size=size; for( int i=0; i<8; i++ ) children[i] = new T; } Octree(){ Octree(0, 0, 0, 10); } // place newchild in array at [i] void set_child(int i, T* newchild){ children[i] = newchild; } // return child at [i] T* get_child(int i){ return children[i]; } // place newchild at [i] and return the old [i] T* swap_child(int i, T* newchild){ T* p = children[i]; children[i] = newchild; return p; } }; int main(){ Octree< Octree<Block> > here; std::cout << "nothing seems to have broken" << std::endl; } Also, as for the problems with set_child, get_child and swap_child leading to possible memory leaks this will be solved as a wrapper class will either use get before set or use swap to get the old child and write this out to disk before freeing the memory itself. I am glad that it is not my memory management failing but rather another error. I have not made a copy and/or assignment operator yet as I was just testing the block tree out, I will almost certainly make them all private very soon. This version spits out -1073741819. Thank you all for your suggestions and I apologise for highjacking my own thread :$

  • Loading a SWF dynamically causes previously loaded SWFs to misbehave

    - by Aaron
    I have run into a very strange problem with Flash and Flex. It appears that under certain circumstances, movie clips from a SWF loaded at runtime (using Loader) cannot be instantiated if another SWF has been loaded in the mean time. Here is the complete code for a program that reproduces the error. It is compiled using mxmlc, via Ensemble Tofino: package { import flash.display.*; import flash.events.*; import flash.net.*; import flash.system.*; public class DynamicLoading extends Sprite { private var testAppDomain:ApplicationDomain; public function DynamicLoading() { var request:URLRequest = new URLRequest("http://localhost/content/test.swf"); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTestLoadComplete); loader.load(request); } private function onTestLoadComplete(e:Event):void { var loaderInfo:LoaderInfo = LoaderInfo(e.target); testAppDomain = loaderInfo.applicationDomain; // To get the error, uncomment these lines... //var request:URLRequest = new URLRequest("http://localhost/content/tiny.swf"); //var loader:Loader = new Loader(); //loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTinyLoadComplete); //loader.load(request); // ...and comment this one: onTinyLoadComplete(); } private function onTinyLoadComplete(e:Event = null):void { var spriteClass:Class = Class(testAppDomain.getDefinition("TopSymbol")); var sprite:Sprite = Sprite(new spriteClass()); sprite.x = sprite.y = 200; addChild(sprite); } } } With the second loading operation commented out as shown above, the code works. However, if the second loading operation is uncommented and onTinyLoadComplete runs after the second SWF is loaded, the line containing new spriteClass() fails with the following exception: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@2dc8ba1 to SubSymbol. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at TopSymbol() at DynamicLoading/onTinyLoadComplete()[C:\Users\...\TestFlash\DynamicLoading.as:38] test.swf and tiny.swf were created in Flash CS4. test.swf contains two symbols, both exported for ActionScript, one called TopSymbol and one called SubSymbol. SubSymbol contains a simple graphic (a scribble) and TopSymbol contains a single instance of SubSymbol. tiny.swf contains nothing; it is the result of publishing a new, empty ActionScript 3 project. If I modify test.swf so that SubSymbol is not exported for ActionScript, the error goes away, but in our real project we need the ability to dynamically load sprite classes that contain other, exported sprite classes as children. Any ideas as to what is causing this, or how to fix it?

  • Small objects allocator

    - by Felics
    Hello, Has anybody used SmallObjectAllocator from Modern C++ Design by Andrei Alexandrescu in a big project? I want to implement this allocator but I need some opinions about it before using it in my project. I made some tests and it seems very fast, but the tests were made in a small test environment. I want to know how fast it is when are lots of small objects(like events, smart pointers, etc) and how much extra memory it uses.

  • dynamically created controls and responding to control events

    - by Dirk
    I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls. protected override void OnLoad(EventArgs e) { base.OnLoad(e); RenderDynamicControls() } private void RenderDynamicControls(){ //1. call service layer to retrieve form definition //2. create and add controls to page container } I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code: protected void MyButton_Click(object sender, EventArgs e) { RenderDynamicControlsALittleDifferently() } private void RenderDynamicControlsALittleDifferently() (){ //1. clear all controls from the page container added in RenderDynamicControls() //2. call service layer to retrieve form definition //3. create and add controls to page container } My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid. On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax. Any code/advice that make that transition easier would be much appreciated. Thanks

  • Hotfixing Code running inside Web Container with Groovy

    - by raoulsson
    I have a webapp running that has a bug. I know how to fix it in the sources. However I cannot redeploy the app as I would have to take it offline to do so. (At least not right now). I now want to fix the code "at runtime". Surgery on the living object, so to speak. The app is implemented in Java and is build on top of Seam. I have added a Groovy Console to the app previous to the last release. (A way to run arbitrary code at runtime) The normal way of adding behaviour to a class with Groovy would be similar to this: String.metaClass.foo= { x -> x * x } println "anything".foo(3) This code added the method foo to java.lang.String and prints 9. I can do the same thing with classes running inside my webapp container. New instances will thereafter show the same behaviour: com.my.package.SomeService.metaClass.foo= { x -> x * x } def someService = new com.my.package.SomeService() println someService.foo(3) Works as excpected. All good so far. My problem is now that the container, the web framework, Seam in this case, has already instantiated and cached the classes that I would like to manipulate (that is change their behaviour to reflect my bug fix). Ideally this code would work: com.my.package.SomeService.metaClass.foo= { x -> x * x } def x = org.jboss.seam.Component.getInstance(com.my.package.SomeService) println x.foo(3) However the instantiation of SomeService has already happened and there is no effect. Thus I need a way to make my changes "sticky". Has the groovy magic gone after my script has been run? Well, after logging out and in again, I can run this piece of code and get the expected result: def someService = new com.my.package.SomeService() println someService.foo(3) So the foo method is still around and it looks like my change has been permanent... So I guess the question that remains is how to force Seam to re-instantiate all its components and/or how to permanently make the change on all living instances...?

  • Problem with using malloc in link lists (urgent ! help please)

    - by Abhinav
    I've been working on this program for five months now. Its a real time application of a sensor network. I create several link lists during the life of the program and Im using malloc for creating a new node in the link. What happens is that the program suddenly stops or goes crazy and restarts. Im using AVR and the microcontroller is ATMEGA 1281. After a lot of debugging I figured out that that the malloc is causing the problem. I do not free the memory after exiting the function that creates a new link so Im guessing that this is eventually causing the heap memory to overflow or something like that. Now if I use the free() function to deallocate the memory at the end of the function using malloc, the program just gets stuck when the control reaches free(). Is this because the memory becomes too clustered after calling free() ? I also create reference tables for example if 'head' is a new link list and I create another list called current and make it equal to head. table *head; table *current = head; After the end of the function if I use free free(current); current = NULL: Then the program gets stuck here. I dont know what to do. What am I doing wrong? Is there a way to increase the size of the heap memory Please help...

  • Is this an example for parametric polymorphism?

    - by mrt181
    Hi i am educating myself oop principles. I would like to know if this is a correct example of Cardellis definition of parametric polymorphism. Please enlighten me. The example is in cfml's script based syntax. <cfcomponent> <cfscript> public numeric function getlength(any arg, string type){ switch (arguments.type){ case "array": return arraylen(arguments.arg); break; case "struct": return structcount(arguments.arg); break; case "string": return len(arguments.arg); break; case "numeric": return len(arguments.arg); break; case "object": // gets the number of parent classes, substracting the railo base class return -1 + arraylen(structfindkey(getmetadata(arguments.arg),"extends","all")); break; default: // throw was added to railo as a user defined function to use it in cfscript throw("InvalidTypeArgument","The provided type argument is invalid for method getlength"); } } </cfscript> </cfcomponent>

  • Ruby: Add a method to the class of an input parameter

    - by TJB
    I'm just exploring ruby and was wondering about the theoretical possibility of adding a method to the class of an object. For example, define a method that takes in a parameter and would add a method to the class of that parameter (not just to the parameter object itself). Something like this example: class SomeClass end class AnotherClass end alpha = SomeClass.new beta = AnotherClass.new def AddHelloMethodTo param # This is where I'm trying to # add a method to the class of the parameter def param.class.Hello "Hello" end end AddHelloMethodTo alpha AddHelloMethodTo beta gamma = AnotherClass.new alpha.Hello beta.Hello gamma.Hello (Excuse me if I have syntax errors / typos I'm REALLY new to this!) Notice how I don't call the AddHelloMethodTo on gamma but I expect Hello to be defined because I added it to the class. Is this possible?

  • Would dynamically created JavaScript files be cached?

    - by venksster
    So my application uses a LOT of js files. thats a lot of http requests. I decided to combine them dynamically at the server in packs of 3-4 files clubbed by functionality. My client side request is: ...script type="text/javascript" src="http://mydomain.com/core-js.php" ... My server side does: --core-js.php-- header("Content-type: application/x-javascript"); include_once('file1.js'); include_once('file2.js'); include_once('file3.js'); include_once('file4.js'); I am setting a far future expire header on core-js.php. My question is, would core-js.php be cached at the client side? If it would be, could someone please explain how? Thanks!

  • How to modify web page elements loaded in a browser

    - by Trilok
    I want to associate some actions with keys (of a keyboard) and then modify the contents of a webpage loaded in the browser. For example, I'll write a firefox plugin and that would be listening to some keyboard events. Based on a key press (or something like that) I want to modify the html code of the page. For example, I would like to change the color of a link. Any suggestions on how can I go about doing this?

  • New to Android: Dynamically changing views

    - by Josiah Kiehl
    I'm trying to learn how to build apps for Android. The first simple app, which will become a component of a bigger app I hope to build, is to have a button on the screen where, when tapped, it adds something new to the view. For instance: Imagine a layout that only has a button: [Create!] When that button, the view gets a new row added to it: [Create!] A Something! Upon subsequent presses, more rows are added [Create!] A Something! A Something! And so on. I've made a LinearLayout and placed the button in it, and have attached a click listener to it. That all works great. What I can't figure out is how to get a handle on the LinearLayout in the onClick function with which I'll addView() the new TextView that says "A Something!" Am I on the right track? What basic thing am I missing? Thanks!

  • ASP.net drop down dynamically styling and then remembering the styles on aborted submit

    - by peacedog
    So, I've got an ASP drop down list (this is .net 2.0). I'm binding it with data. Basically, when the page loads and it's not a post back we'll fetch record data, bind all the drop downs, and set them to their appropriate values (strictly speaking we: initialize page with basic set of data from DB, bind drop downs from DB, fetch actual record data from DB, set drown downs to appropriate settings at this time). What I want to do is selectively style the list options. So the database returns 3 items: ID, Text, and a flag indicating whether I the record is "active" (and I'll style appropriately). It's easy enough to do and I've done it. My problem is what happens when a form submission is halted. We have slightly extended the Page class and created an AddError() method, which will create a list of errors from failed business rule checks and then display them in a ValidationSummary. It works something like this, in the submit button's click event: CheckBizRules(); if(Page.IsValid) { SaveData(); } If any business rule check fails, the Page will not be valid. The problem is, when the page re-renders (viewsate is enabled, but no data is rebound) my beautiful conditional styling is now sadly gone, off to live in the land of the missing socks. I need to preserve it. I was hoping to avoid another DB call here (e.g. getting the list data back from the DB again if the page isn't valid, just for purposes of re-styling the list). But it's not the end of the world if that's my course of action. I was hoping someone might have an alternative suggestion. I couldn't think of how to phrase this question better, if anyone has any suggestions or needs clarification don't hesitate to get it, by force if need be. ;)

  • Can search engines index JavaScript generated web pages?

    - by Roy
    Can search engines such as Google index JavaScript generated web pages? When you right click and select view source in a page that is generated by JavaScript (e.g using GWT) you do not see the dynamically generated HTML. I suppose that if a search engine also cannot see the generated HTML then there is not much to index, right?
