  • Flash - can't access classes in another SWF

    - by Ashley Muller
    Hi, I'm trying to load a local SWF file and use the classes in that SWF (its a code only SWF, nothing in library). Here's the code that loads the library: var AD:ApplicationDomain = ApplicationDomain.currentDomain; var context:LoaderContext = new LoaderContext(false, AD); SA_gamecore_loader = new Loader(); SA_gamecore_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onGameCoreLibraryDataComplete); SA_gamecore_loader.load(new URLRequest("GameCore.swf"), context); Here's the code that tries to instantiate a class from GameCore.swf: var test:Class = GetClassFromDefinition("MenuArt") as Class; var testInstance:Object = new test(); public function GetClassFromDefinition(theStr:String):Object { var theClass:Object; try { theClass = GameCoreLibraryData.applicationDomain.getDefinition(theStr); } catch(e:ReferenceError) { trace(e); return null; } return theClass; } And this is the message that's traced: ReferenceError: Error #1065: Variable MenuArt is not defined. The GameCore.swf is in the same location as the parent swf. I'm using Flash Develop if that helps. Anyone able to point out what I'm doing wrong?

  • Optimizing this "Boundarize" method for Numerics in Ruby

    - by mstksg
    I'm extending Numerics with a method I call "Boundarize" for lack of better name; I'm sure there are actually real names for this. But its basic purpose is to reset a given point to be within a boundary. That is, "wrapping" a point around the boundary; if the area is betweeon 0 and 100, if the point goes to -1, -1.boundarize(0,100) = 99 (going one too far to the negative "wraps" the point around to one from the max). 102.boundarize(0,100) = 2 It's a very simple function to implement; when the number is below the minimum, simply add (max-min) until it's in the boundary. If the number is above the maximum, simply subtract (max-min) until it's in the boundary. One thing I also need to account for is that, there are cases where I don't want to include the minimum in the range, and cases where I don't want to include the maximum in the range. This is specified as an argument. However, I fear that my current implementation is horribly, terribly, grossly inefficient. And because every time something moves on the screen, it has to re-run this, this is one of the bottlenecks of my application. Anyone have any ideas? module Boundarizer def boundarize min=0,max=1,allow_min=true,allow_max=false raise "Improper boundaries #{min}/#{max}" if min >= max new_num = self if allow_min while new_num < min new_num += (max-min) end else while new_num <= min new_num += (max-min) end end if allow_max while new_num > max new_num -= (max-min) end else while new_num >= max new_num -= (max-min) end end return new_num end end class Numeric include Boundarizer end

  • QT NOOB: Add action handler for multiple objects of same type.

    - by what
    I have a simple QT application with 10 radio buttons with names radio_1 through radio_10. It is a ui called Selector, and is part of a class called TimeSelector In my header file for this design, i have this: //! [1] class TimeSelector : public QWidget { Q_OBJECT public: TimeSelector(QWidget *parent = 0); private slots: //void on_inputSpinBox1_valueChanged(int value); //void on_inputSpinBox2_valueChanged(int value); private: Ui::Selector ui; }; //! [1] the commented out void_on_inputSpinBox1_valueChanged(int value) is from the tutorial for the simple calculator. I know i can do: void on_radio_1_valueChanged(int value); but I would need 10 functions. I want to be able to make one function that works for everything, and lets me pass in maybe a name of the radio button that called it, or a reference to the radio button so i can work with it and determine who it was. I am very new to QT but this seems like it should be very basic and doable, thanks.

  • How to pass common arguments to Perl modules

    - by Leonard
    I'm not thrilled with the argument-passing architecture I'm evolving for the (many) Perl scripts that have been developed for some scripts that call various Hadoop MapReduce jobs. There are currently 8 scripts (of the form run_something.pl) that are run from cron. (And more on the way ... we expect anywhere from 1 to 3 more for every function we add to hadoop.) Each of these have about 6 identical command-line parameters, and a couple command line parameters that are similar, all specified with Euclid. The implementations are in a dozen .pm modules. Some of which are common, and others of which are unique.... Currently I'm passing the args globally to each module ... Inside run_something.pl I have: set_common_args (%ARGV); set_something_args (%ARGV); And inside Something.pm I have sub set_something_args { (%MYARGS) =@_; } So then I can do if ( $MYARGS{'--needs_more_beer'} ) { $beer++; } I'm seeing that I'm probably going to have additional "common" files that I'll want to pass args to, so I'll have three or four set_xxx_args calls at the top of each run_something.pl, and it just doesn't seem too elegant. On the other hand, it beats passing the whole stupid argument array down the call chain, and choosing and passing individual elements down the call chain is (a) too much work (b) error-prone (c) doesn't buy much. In lots of ways what I'm doing is just object-oriented design without the object-oriented language trappings, and it looks uglier without said trappings, but nonetheless ... Anyone have thoughts or ideas?

  • Stopping work from one thread using another thread

    - by 113483626144458436514
    Not sure if my title is worded well, but whatever :) I have two threads: the main thread with the work that needs to be done, and a worker thread that contains a form with a progress bar and a cancel button. In normal code, it would be the other way around, but I can't do that in this case. When the user clicks the cancel button, a prompt is displayed asking if he wants to really cancel the work. The problem is that work continues on the main thread. I can get the main thread to stop work and such, but I would like for it to stop doing work when he clicks "Yes" on the prompt. Example: // Main thread work starts here t1 = new Thread(new ThreadStart(progressForm_Start)); t1.Start(); // Working for (i = 0; i <= 10000; i++) { semaphore.WaitOne(); if (pBar.Running) bgworker_ProgressChanged(i); semaphore.Release(); if (pBar.IsCancelled) break; } t1.Abort(); // Main thread work ends here // Start progress bar form in another thread void progressForm_Start() { pBar.Status("Starting"); pBar.ShowDialog(); } I could theoretically include a prompt in the cancelWatch() function, but then I would have to do that everywhere I'm implementing this class.

  • Suggestions on error handling of Win32 C++ code: AtlThrow vs. STL exceptions

    - by EmbeddedProg
    In writing Win32 C++ code, I'd appreciate some hints on how to handle errors of Win32 APIs. In particular, in case of a failure of a Win32 function call (e.g. MapViewOfFile), is it better to: use AtlThrowLastWin32 define a Win32Exception class derived from std::exception, with an added HRESULT data member to store the HRESULT corresponding to value returned by GetLastError? In this latter case, I could use the what() method to return a detailed error string (e.g. "MapViewOfFile call failed in MyClass::DoSomething() method."). What are the pros and cons of 1 vs. 2? Is there any other better option that I am missing? As a side note, if I'd like to localize the component I'm developing, how could I localize the exception what() string? I was thinking of building a table mapping the original English string returned by what() into a Unicode localized error string. Could anyone suggest a better approach? Thanks much for your insights and suggestions.

  • Continue gif animation after escape is pressed

    - by cottsak
    Firefox (and other browsers i believe) stop gif animation when you click the Stop button or invoke it via the Escape key. I have a text input that on change makes ajax requests to update other elements. As part of this ajaxyness i have an animated gif to show feedback. I also trap the escape key press in this input so as to clear the text field for better UX. My problem is after the escape key is pressed once, none of the ajax gifs animate anymore until the page is refreshed. Does anyone know a workaround? Stuff i've tried: I tried the e.stopPropagation(); and e.cancelBubble = true; in the function handling the e.keyCode == 27 and that didn't seem to work. I suspect that this stops trigging more js events and the browser catches the escape irrespective of js activity. I have the gif showing/hiding via adding/removing a css class so it's difficult to apply the "change gif url to reset" workaround. I dont even know if this works anyway - didn't test it. But it seems difficult. If anyone knows that this works and knows of an easy way to apply the hack with background-image: url(../images/ajax-loader_dotcirclel13x13.gif); css then please let me know.

  • Compilation problem in the standard x86_64 libraries

    Hi everyone, I am having trouble compiling a program I have written.

  • is there something equivalent to 'Address of' or offset operator in .net?

    - by Gio
    We have nested stuctures as such, used as an interface for some device drivers. On occasion we have to update individual elements. An 'address of' operator would be helpful, but an 'offset' function or operator is what I'm really looking for, but not sure how to go about it. In other words, how far is structureN.elementX away from the start of the structure in bytes? [StructLayout(LayoutKind.Sequential)] public struct s1 { UInt16 elem1; UInt16 elem2; UInt16 elem3; } [StructLayout(LayoutKind.Sequential)] public struct s2 { UInt16 elem1; UInt16 elem2; UInt16 elem3; } [StructLayout(LayoutKind.Sequential)] public struct driver { public S1 s1; public S2 s2; } For instance we need to send the device driver some data to update driver.s1.elem3, by way of providing an offset address, data block and length. We would update our local copy, then call the device api with the afore mentioned data. Not sure I have to do this with 'unsafe' method calls. Any help?

  • Execute SSH commands on Cisco router. Codeigniter SSH library

    - by jomajo
    I have a little problem. I'm using Codeigniter with SSH library written by Shuky (https://bitbucket.org/quicktips/codeigniter-ssh2-library/src/a444968345ba/SSH.php -- You can see the code by following this link). Everything related with SSH works fine with other devices, but when I try to use this library and execute commands on Cisco devices, nothing happens (commands are not executed). I know that the connection is successful, but I can't execute any commands. When I try to run and execute comands through SSH on Cisco devices I get this error: A PHP Error was encountered Severity: Warning Message: stream_set_blocking() expects parameter 1 to be resource, boolean given Filename: libraries/SSH.php Line Number: 128 A PHP Error was encountered Severity: Warning Message: fread() expects parameter 1 to be resource, boolean given Filename: libraries/SSH.php Line Number: 129 In the library these lines look like this: /** * Get stream data * * @access privte * @return bool */ function _get_stream_data($stream) { stream_set_blocking( $stream, true ); while( $buf = fread($stream,4096) ) { $this->data .= $buf.'~'; } return TRUE; } line 128 - stream_set_blocking( $stream, true ); line 129 - while( $buf = fread($stream,4096) ) { Maybe you guys know where the problem is?

  • Regex Replacing only whole matches

    - by Leen Balsters
    I am trying to replace a bunch of strings in files. The strings are stored in a datatable along with the new string value. string contents = File.ReadAllText(file); foreach (DataRow dr in FolderRenames.Rows) { contents = Regex.Replace(contents, dr["find"].ToString(), dr["replace"].ToString()); File.SetAttributes(file, FileAttributes.Normal); File.WriteAllText(file, contents); } The strings look like this _-uUa, -_uU, _-Ha etc. The problem that I am having is when for example this string "_uU" will also overwrite "_-uUa" so the replacement would look like "newvaluea" Is there a way to tell regex to look at the next character after the found string and make sure it is not an alphanumeric character? I hope it is clear what I am trying to do here. Here is some sample data: private function _-0iX(arg1:flash.events.Event):void { if (arg1.type == flash.events.Event.RESIZE) { if (this._-2GU) { this._-yu(this._-2GU); } } return; } The next characters could be ;, (, ), dot, comma, space, :, etc.

  • null terminating a string

    - by robUK
    Hello, gcc 4.4.4 c89 just wondering what is the standard way to null terminate a string. i.e. However, when I use the NULL I get the warning message. *dest++ = 0; *dest++ = '\0'; *dest++ = NULL; /* Warning: Assignment takes integer from pointer without a cast */ source code I am using: size_t s_strscpy(char *dest, const char *src, const size_t len) { /* Copy the contents from src to dest */ size_t i = 0; for(i = 0; i < len; i++) *dest++ = *src++; /* Null terminate dest */ *dest++ = 0; return i; } Just another quick question. I deliberately commented out the line that null terminates. However, it still correctly printed out the contents of the dest. The caller of this function would send the length of the string by either included the NULL or not. i.e. strlen(src) + 1 or stlen(src). size_t s_strscpy(char *dest, const char *src, const size_t len) { /* Copy the contents from src to dest */ size_t i = 0; /* Don't copy the null terminator */ for(i = 0; i < len - 1; i++) *dest++ = *src++; /* Don't add the Null terminator */ /* *dest++ = 0; */ return i; } Many thanks for any advice,

  • Defining and using controller methods in ember.js

    - by OriginalEXE
    first of all, I am total noob when it comes to OOP in JS, this is new to me so treat me like a noob. I am building my first ember.js application and I am stuck (not the first time but I would get unstuck by myself, this is a tough one though). I have two models: forms entries Entries is of course in (one to many) relationship to forms, so each form can have as many properties. Form properties: id : DS.attr( 'number' ), title : DS.attr( 'string' ), views : DS.attr( 'number' ), conversion : DS.attr( 'number' ), entries : DS.hasMany( 'entry' ) Entry properties: id : DS.attr( 'number' ), parent_id: DS.belongsTo( 'form' ) Now, I have forms route that displays all forms in tabled view, and each table row has some info like form id, name etc. and that works great. What I wanted to do is display the number of entries each form has. I figured I should do that via controller, so here is my controller now: // Form controller App.FormController = Ember.ObjectController.extend({ entriescount: function() { var entries = this.get( 'store').find( 'entry' ); return entries.filterBy( 'parent_id', this.get( 'id' ) ).get( 'length' ); }.property( '[email protected]_id') }); Now for some reason, when I use {{entriescount}} in {{#each}} loop, this returns nothing. It also returns nothing in single form route. Note that in both cases, {{title}} for example works. I am wondering, am I going the right way by using controller for this, and how do I get controller to output the data. Thanks

  • cython setup.py gives .o instead of .dll

    - by alok1974
    Hi, I am a newbie to cython, so pardon me if I am missing something obvious here. I am trying to build c extensions to be used in python for enhanced performance. I have fc.py module with a bunch of function and trying to generate a .dll through cython using dsutils and running on win64: c:\python26\python c:\cythontest\setup.py build_ext --inplace I have the dsutils.cfg in C:\Python26\Lib\distutils. As required the disutils.cfg has the following config settings: [build] compiler = mingw32 My startup.py looks like this: from distutils.core import setup from distutils.extension import Extension from Cython.Distutils import build_ext ext_modules = [Extension('fc', [r'C:\cythonTest\fc.pyx'])] setup( name = 'FC Extensions', cmdclass = {'build_ext': build_ext}, ext_modules = ext_modules ) I have latest version mingw for target/host amdwin64 type builds. I have the latest version of cython for python26 for win64. Cython does give me an fc.c without errors, only a few warning for type conversions, which I will handle once I have it right. Further it produces fc.def an fc.o files Instead of giving a .dll. I get no errors. I find on threads that it will create the .so or .dll automatically as required, which is not happening.

  • Magento help with creating model in custom class

    - by dardub
    I'm trying to add some custom filter methods to my magento module. I though it would be simple but I can't figure out why it's not working. My model which extends the catalog/product class contains this: public function filterProdType($prod_id) { $this->addAttributeToFilter('attribute_set_id', $prod_id); } Then in my template I have this: $collection = Mage::getModel('configurator/product')->getCollection()->addAttributeToSelect('*'); $collection->filterProdType(50)->addAttributeToFilter('type_id', 'bundle'); foreach ($collection as $item){ echo $item->getName() . ', '; } Just to try things out. But I don't get any results, no error, and it doesn't finish rendering the page (missing footer). When I do this instead, it works: $collection = Mage::getModel('configurator/product')->getCollection()->addAttributeToSelect('*'); $collection->addAttributeToFilter('attribute_set_id', 50)->addAttributeToFilter('type_id', 'bundle'); foreach ($collection as $item){ echo $item->getName() . ', '; } I'm just wondering what I'm missing. UPDATE: I didn't realize error reporting was turned off, after turning it on I get the error: Fatal error: Call to undefined method Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection::filterProdType() I assumed after instantiating $collection using my custom model, it would find my new method.

  • Does new JUnit 4.8 @Category render test suites almost obsolete?

    - by grigory
    Given question 'How to run all tests belonging to a certain Category?' and the answer would the following approach be better for test organization? define master test suite that contains all tests (e.g. using ClasspathSuite) design sufficient set of JUnit categories (sufficient means that every desirable collection of sets is identifiable using one or more categories) define targeted test suites based on master test suite and set of categories For example: identify categories for speed (slow, fast), dependencies (mock, database, integration), function (), domain ( demand that each test is properly qualified (tagged) with relevant set of categories. create master test suite using ClasspathSuite (all tests found in classpath) create targeted suites by qualifying master test suite with categories, e.g. mock test suite, fast database test suite, slow integration for domain X test suite, etc. My question is more like soliciting approval rate for such approach vs. classic test suite approach. One unbeatable benefit is that every new test is immediately contained by relevant suites with no suite maintenance. One concern is proper categorization of each test.

    Hi all, I'm using Wysihat in a rails project and am stumped by it's inability to bind to my textarea named post_description (model name Post field name description). I have the following in my head tag: <%= javascript_include_tag 'prototype_1.7'%> <%= javascript_include_tag 'wysihat' %> <script type="text/javascript" charset="utf-8"> document.on("dom:loaded", function() { var editor = WysiHat.Editor.attach('post_description'); var toolbar = new WysiHat.Toolbar(editor); toolbar.addButtonSet(WysiHat.Toolbar.ButtonSets.Basic); // Hide our error message if the editor loads fine $('error').hide(); }); </script> I'm able to see Wysihat works (the bold, italic, and underline tools are shown and when click works as intended). The following in the source of the posts/new HTML: <div id="post_description_editor" class="editor" contenteditable="true"></div> <textarea cols="40" id="post_description" name="post[description]" rows="20" style="display: none; "></textarea> However, when I type something in the description field and click submit the post validation fails saying the description field is empty.

  • Get dragged / saved items state back from Sql Server

    - by user571507
    Ok i saw many post's on how to serialize the value of dragged items to get hash and they tell how to save them. Now the question is how do i persist the dragged items the next time when user log's in using the has value that i got eg: <ul class="list"> <li id="id_1"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_2"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_3"> <div class="item ui-corner-all ui-widget ui-widget-content"> </div> </li> <li id="id_4"> <div class="item ui-corner-all ui-widget"> </div> </li> </ul> which on serialize will give "id[]=1&id[]=2&id[]=3&id[]=4" Now think that i saved it to Sql server database in a single field called SortOrder. Now how do i get the items to these order again ? the code to make these sort is below,without which people didn't know which library i had used to sort and serialize <script type="text/javascript"> $(document).ready(function() { $(".list li").css("cursor", "move"); $(".list").sortable(); }); </script>

  • Best method to search hierarchical data

    - by WDuffy
    I'm looking at building a facility which allows querying for data with hierarchical filtering. I have a few ideas how I'm going to go about it but was wondering if there are any recommendations or suggestions that might be more efficient. As an example imagine that a user is searching for a job. The job areas would be as follows. 1: Scotland 2: --- West Central 3: ------ Glasgow 4: ------ Etc 5: --- North East 6: ------ Ayrshire 7: ------ Etc A user can search specific (i.e. Glasgow) or in a larger area (i.e. Scotland). The two approaches I am considering are: keep a note of children in the database for each record (i.e. cat 1 would have 2, 3, 4 in its children field) and query against that record with a SELECT * FROM Jobs WHERE Category IN Areas.childrenField. Use a recursive function to find all results who have a relation to the selected area. The problems I see from both are: Holding this data in the db will mean having to keep track of all changes to structure. Recursion is slow and inefficent. Any ideas, suggestion or recommendations on the best approach? I'm using C# ASP.NET with MSSQL 2005 DB.

  • Help C++ifying this C style code.

    - by Flamewires
    Hey I'm used to developing in C and I would like to use C++ in a project. Can anyone give me an example of how I would translate this C-style code into C++ code. I know it should compile in a c++ complier but I'm talking using c++ techniques(I.e. classes, RAII) typedef struct Solution Solution; struct Solution { double x[30]; int itt_found; double value; }; Solution *NewSolution() { Solution *S = (Solution *)malloc(sizeof(Solution)); for (int i=0;<=30;i++) { S-x[i] = 0; } S-itt_found = -1; return S; } void FreeSolution(Solution *S) { if (S != NULL) free(S); } int main() { Solution *S = NewSolution(); S-value = eval(S-x);// evals is another function that returns a double S-itt_found = 0; FreeSolution(S); return EXIT_SUCCESS; } Ideally I would like to be able to so something like this in main, but I'm not sure exactly how to create the class, i've read a lot of stuff but incorporating it all together correctly seems a little hard atm. Solution S(30);//constructor that takes as an argument the size of the double array S.eval();//a method that would run eval on S.x[] and store result in S.value cout << S.value << endl; Ask if you need more info, thanks.
