  • Flash AS3 load file xml

    - by Elias
    Hello, I'm just trying to load an xml file witch can be anywere in the hdd, this is what I have done to browse it, but later when I'm trying to load the file it would only look in the same path of the swf file here is the code package { import flash.display.Sprite; import flash.events.; import flash.net.; public class cargadorXML extends Sprite { public var cuadro:Sprite = new Sprite(); public var file:FileReference; public var req:URLRequest; public var xml:XML; public var xmlLoader:URLLoader = new URLLoader(); public function cargadorXML() { cuadro.graphics.beginFill(0xFF0000); cuadro.graphics.drawRoundRect(0,0,100,100,10); cuadro.graphics.endFill(); cuadro.addEventListener(MouseEvent.CLICK,browser); addChild(cuadro); } public function browser(e:Event) { file = new FileReference(); file.addEventListener(Event.SELECT,bien); file.browse(); } public function bien(e:Event) { xmlLoader.addEventListener(Event.COMPLETE, loadXML); req=new URLRequest(file.name); xmlLoader.load(req); } public function loadXML(e:Event) { xml=new XML(e.target.data); //xml.name=file.name; trace(xml); } } } when I open a xml file that isnt it the same directory as the swf, it gives me an unfound file error. is there anything I can do? cause for example for mp3 there is an especial class for loading the file, see http://www.flexiblefactory.co.uk/flexible/?p=46 thanks

  • Rails: Custom template for email "deliver_" method?

    - by neezer
    I'm building an email system that stores my different emails in the database and calls the appropriate "deliver_" method via method_missing (since I can't explicitly declare methods since they're user-generated). My problem is that my rails app still tries to render the template for whatever the generated email is, though those templates don't exist. I want to force all emails to use the same template (views/test_email.html.haml), which will be setup to draw their formatting from my database records. How can I accomplish this? I tried adding render :template => 'test_email' in the test_email method in emailer_controller with no luck. models/emailer.rb: class Emailer < ActionMailer::Base def method_missing(method, *args) # not been implemented yet logger.info "method missing was called!!" end end controller/emailer_controller.rb: class EmailerController < ApplicationController def test_email @email = Email.find(params[:id]) Emailer.send("deliver_#{@email.name}") end end views/emails/index.html.haml: %h1 Listing emails %table{ :cellspacing => 0 } %tr %th Name %th Subject - @emails.each do |email| %tr %td=h email.name %td=h email.subject %td= link_to 'Show', email %td= link_to 'Edit', edit_email_path(email) %td= link_to 'Send Test Message', :controller => 'emailer', :action => 'test_email', :params => { :id => email.id } %td= link_to 'Destroy', email, :confirm => 'Are you sure?', :method => :delete %p= link_to 'New email', new_email_path Error I'm getting with the above: Template is missing Missing template emailer/name_of_email_in_database.erb in view path app/views

  • What is the best way to attach extenstion methods to static classes rather than to instances of a cl

    - by John Gietzen
    If I have a method for calculating the greatest common divisor of two integers as: public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } What would be the best way to attach that to the System.Math class? Here are the three ways I have come up with: public static int GCD(this int a, int b) { return b == 0 ? a : b.GCD(a % b); } // Lame... var gcd = a.GCD(b); and: public static class RationalMath { public static int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); } } // Lame... var gcd = RationalMath.GCD(a, b); and: public static int GCD(this Type math, int a, int b) { return b == 0 ? a : typeof(Math).GCD(b, a % b); } // Neat? var gcd = typeof(Math).GCD(a, b); The desired syntax is Math.GCD since that is the standard for all mathematical functions. Any suggestions? What should I do to get the desired syntax?

  • Rails 3 : create two dimensional hash and add values from a loop

    - by John
    I have two models : class Project < ActiveRecord::Base has_many :ticket attr_accessible .... end class Ticket < ActiveRecord::Base belongs_to :project attr_accessible done_date, description, .... end In my ProjectsController I would like to create a two dimensional hash to get in one variable for one project all tickets that are done (with done_date as key and description as value). For example i would like a hash like this : What i'm looking for : @tickets_of_project = ["done_date_1" => ["a", "b", "c"], "done_date_2" => ["d", "e"]] And what i'm currently trying (in ProjectsController) ... def show # Get current project @project = Project.find(params[:id]) # Get all dones tickets for a project, order by done_date @tickets = Ticket.where(:project_id => params[:id]).where("done_date IS NOT NULL").order(:done_date) # Create a new hash @tickets_of_project = Hash.new {} # Make a loop on all tickets, and want to complete my hash @tickets.each do |ticket| # TO DO #HOW TO PUT ticket.value IN "tickets_of_project" WITH KEY = ticket.done_date ??** end end I don't know if i'm in a right way or not (maybe use .map instead of make a where query), but how can I complete and put values in hash by checking index if already exist or not ? Thanx :)

  • [Asp.Net MVC] Encoding a character

    - by Trimack
    Hi, I am experiencing some weird encoding behaviour in my ASP.NET MVC project. In my Site.Master there is <div class="logo"> <a href="<%=Url.Action("Index", "Win7")%>"><%= Html.Encode("Windows 7 Tutoriál") %></a></div> which translates to the resulting page as <div class="logo"> <a href="/">Windows 7 TutoriA?l</a></div> However, in the Index.aspx there is <h1> Windows 7 Tutoriál</h1> which translates correctly on the same resulting page. I do have <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> as my first line in <head>. Locally, both files are saved in UTF-8 encoding. Any ideas why is this happening and how to fix it? Thanks in advance.

  • Modify Executing Jar file

    - by pinkynobrain
    Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

  • ASP Calendar Date Pick

    I am attempting to construct my own date picker using code from several sources. Specifically, I am now populating the textbox with a calendar click.

  • Using XmlSerializer deserialize complex type elements are null

  • performSelectorInBackground: using self.object ?

    - by Emil
    Hey. I am trying to load an image for a custom tableViewCell. The code gets run from the CustomCell-class (CustomCell.h) from [cell performSelectorInBackground:@selector(loadImageFromURL:) withObject:[NSURL URLWithString:urlString]]; in the cellForRowAtIndexPath:-function. Cell gets created here: CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id currentObject in topLevelObjects){ if ([currentObject isKindOfClass:[CustomCell class]]){ cell = (CustomCell *) currentObject; break; } } } CustomCell.h: // ... IBOutlet UIImageView *cellImage; } - (void) loadImageFromURL:(NSURL *)url; // … CustomCell.m: - (void) loadImageFromURL:(NSURL *)url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"Loading image..."); [loadingImage startAnimating]; [self.cellImage setImageWithURL:url]; [loadingImage stopAnimating]; NSLog(@"Done loading image..."); [pool release]; } setImageWithURL: is a function from the SDWebImage-framework that rs has made. The real error is that the image doesen't show up. EDIT: When I cleared the app's cache, the images didn't show up anymore. EDIT: Seems like URL is nil for some reason. Am I passing the object in the selector correctly? Can you see anything wrong? Thanks.

  • How do I use a modalViewController Identically in Two Controllers?

    - by Theory
    I'm using the Three20 TTMessageController in my app. I've figured out how to use it, adding on a bunch of other stuff (including TTMessageControllerDelegate methods and ABPeoplePickerNavigationControllerDelegate methods). It works great for me, after a bit of a struggle to figure it out. The trouble I'm having now is a design issue: I want to use it identically in two different places, including with the same delegate methods. My current approach is that I've put all the code into a single class inheriting from NSObject, called ComposerProxy, and I'm just having the two controllers that use it use the proxy, like so: ComposerProxy *proxy = [[ComposerProxy alloc] initWithController:this]; [proxy go]; The go method constructs the TTMessageController, configures it, adds it to a UINavigationController, and presents it: [self.controller presentModalViewController: navController animated: YES]; This works great, as I have all my code nicely encapsulated in ComposerProxy and I need only the above two lines anywhere I want to use it. The downside, though, is that I can't dealloc the proxy variable without getting crashes. I can't autorelease it, either: same problem. So I'm wondering if my proxy approach is a poor one. How does one normally encapsulate a bunch of behaviors like this without requiring a lot of duplicate code in the classes that use it? Do I need to add a delegate class to my ComposerProxy and make the controller responsible for dismissing the modal view controller in a hypothetical composerDidFinish method or some such? Many TIA!

  • In VB.net websites, VS2008 ALWAYS uses space indentation for new files

    - by Jez
    So, I've changed my settings in Tools | Options | Text Editor, for All Languages, Basic, and C#, to having Block indenting, and 'Keep tabs'. I've also tried this with Smart indenting too. Now, although once I start editing a file, its auto indentation is done with tabs, when I create a new web form in my ASP.net website, VS2008 insists on creating the initial code with space indentation. So for example, I'll get an aspx.vb file for my new page like so: Partial Class Admin_Index Inherits System.Web.UI.Page End Class Note that the 'Inherits' line is SPACE-indented, even though I have the text editor settings set to keep tabs. Is there any way I can make the default created files indented with tabs, not spaces? Or is VS just too stubborn? :-) By the way, please don't just respond and say this is petty as I can quickly change that one line of indentation to using a tab. I know this, but I have a software team that find it irritating as we have an SVN hook that prevents checkins if there's any space-indentation. It would be very useful if any newly-created files have tab indentation from the start, rather than us having to change it every time.

  • How much business logic belongs in RIA services layer?

    - by jkohlhepp
    I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application on top of this stack should be architected. The main issue I have is that in most of the demos I've seen most of the business logic ends up as DataAnnotations and custom validations in the RIA Services domain service class. This seems inappropriate to me. I view the domain service as basically a glorified web service that happens to make it easy to push information to the client. But most of what I've seen seems to orient the domain service as the main source of business logic in the application. So, my questions: What is the best location for business logic (rules, validations, behaviors, authorization) in an application using this stack? Are there any guidelines published at an architectural level for using this stack? My questions pertain to large, complex, and long-lived applications. Obviously for an application of only a few screens this is less of a concern. Edit: Another thing I meant to mention is that obviously you can make the domain service class stupid, but then you lose a lot of the automagic entity information (e.g. validations) being pushed to the client. And then if you lose that is there any point to using RIA services?

  • Help me understand Inorder Traversal without using recursion

    - by vito
    I am able to understand preorder traversal without using recursion, but I'm having a hard time with inorder traversal. I just don't seem to get it, perhaps, because I haven't understood the inner working of recursion. This is what I've tried so far: def traverseInorder(node): lifo = Lifo() lifo.push(node) while True: if node is None: break if node.left is not None: lifo.push(node.left) node = node.left continue prev = node while True: if node is None: break print node.value prev = node node = lifo.pop() node = prev if node.right is not None: lifo.push(node.right) node = node.right else: break The inner while-loop just doesn't feel right. Also, some of the elements are getting printed twice; may be I can solve this by checking if that node has been printed before, but that requires another variable, which, again, doesn't feel right. Where am I going wrong? I haven't tried postorder traversal, but I guess it's similar and I will face the same conceptual blockage there, too. Thanks for your time! P.S.: Definitions of Lifo and Node: class Node: def __init__(self, value, left=None, right=None): self.value = value self.left = left self.right = right class Lifo: def __init__(self): self.lifo = () def push(self, data): self.lifo = (data, self.lifo) def pop(self): if len(self.lifo) == 0: return None ret, self.lifo = self.lifo return ret

  • PHP Variable with Array

    - by Crays
    Hi guys, i'm trying to make a "update user's power" page. It is something similar to those you can find in say, invisionfree forums. I need it to generate a list of members with checkbox [done] Add an option for it [done] What i don't know how to do is to update, to say, give all the selected users the selected power. Then i went searching for something and found most of them uses array to do this, but i never found one that actually explains how it works. The example i took (with my own modification) was this: while($row = mysql_fetch_array($result)) { echo '<tr>'.$id[]=$rows['id'].''; echo '<td width="50px" align="center" class="TableFormCell"><input type="checkbox" name="option[]" /></td>'; echo '<td width="170px" align="center" class="TableFormCell">'.$row['uname'].'</td>'; echo '</tr>'; } I'm not sure what exactly $id[]=$rows['id'] does I know after the row, my option[] would become an array of option[1], option[2], option[3] for what power should be given, i've got no problem with that but on how to update the database i'm got no clue... for($i=0;$i<$count;$i++){ $sql1="UPDATE ninos SET power='$power' WHERE id='$option[$i]'"; $result1=mysql_query($sql1); } So Say i have 5 users, Aye, Bee, Cee, Dee, Eee with IDs of 1,2,3,4,5 how can i make it so that my script would run like $sql1="UPDATE ninos SET power = '$power' Where id='1','2','3','4','5'"; Please help, thanks.

  • What would be the safest way to store objects of classes derived from a common interface in a common

    - by Svenstaro
    I'd like to manage a bunch of objects of classes derived from a shared interface class in a common container. To illustrate the problem, let's say I'm building a game which will contain different actors. Let's call the interface IActor and derive Enemy and Civilian from it. Now, the idea is to have my game main loop be able to do this: // somewhere during init std::vector<IActor> ActorList; Enemy EvilGuy; Civilian CoolGuy; ActorList.push_back(EvilGuy); ActorList.push_back(CoolGuy); and // main loop while(!done) { BOOST_FOREACH(IActor CurrentActor, ActorList) { CurrentActor.Update(); CurrentActor.Draw(); } } ... or something along those lines. This example obviously won't work but that is pretty much the reason I'm asking here. I'd like to know: What would be the best, safest, highest-level way to manage those objects in a common heterogeneous container? I know about a variety of approaches (Boost::Any, void*, handler class with boost::shared_ptr, Boost.Pointer Container, dynamic_cast) but I can't decide which would be the way to go here. Also I'd like to emphasize that I want to stay away as far as possible from manual memory management or nested pointers. Help much appreciated :).

    Hi All I am trying to build a shopping website with ajax. When a user clicks the "add to cart" image. The little loading image will show next to the Add To Cart Image. The first click works fine and the image showed as I expected. However, the second and the following clicks appends more images on the first loading image(2nd:add two loading images, 3rd: add three images..6 total images after 3 clicks). I did use ajaxStop and remove the first image...Not sure what's going on...Could use a help. Thanks a lot.

  • How to profile Doctrine in Zend Framework

    - by David Zapata
    Good day. I'm using Doctrine as ORM for my Zend Framework project. This is the first time I use it. I've followed the ZendCasts Doctrine chapters, and everything works for me, but I needed to perform some profiling; There is a Doctrine_Connection_Profiler class that should be used to profile the Doctrine Model internal queries, but I've tried to use it without success. I always get a "PDOException: You cannot serialize or unserialize PDOStatement instances" exception when I perform my Unit Tests. Here is a example: $conn = Doctrine_Manager::connection($doctrineConfig['dsn'], $dbconfname); ... if( APPLICATION_ENV != 'production'){ $obj_doctrine_profiler = new Doctrine_Connection_Profiler(); $conn->setListener($obj_doctrine_profiler); } All of my Unit Tests works if I comment/delete the $conn->setListener($obj_doctrine_profiler); line. This code block is located in my Bootstrap.php class; the weird thing is, the web application works just fine even with the mentioned code line. Thank you so much for your help. please excuse me if my english is not the best.

  • Datastore performance, my code or the datastore latency

    - by fredrik
    I had for the last month a bit of a problem with a quite basic datastore query. It involves 2 db.Models with one referring to the other with a db.ReferenceProperty. The problem is that according to the admin logs the request takes about 2-4 seconds to complete. I strip it down to a bare form and a list to display the results. The put works fine, but the get accumulates (in my opinion) way to much cpu time. #The get look like this: outputData['items'] = {} labelsData = Label.all() for label in labelsData: labelItem = label.item.name if labelItem not in outputData['items']: outputData['items'][labelItem] = { 'item' : labelItem, 'labels' : [] } outputData['items'][labelItem]['labels'].append(label.text) path = os.path.join(os.path.dirname(__file__), 'index.html') self.response.out.write(template.render(path, outputData)) #And the models: class Item(db.Model): name = db.StringProperty() class Label(db.Model): text = db.StringProperty() lang = db.StringProperty() item = db.ReferenceProperty(Item) I've tried to make it a number of different way ie. instead of ReferenceProperty storing all Label keys in the Item Model as a db.ListProperty. My test data is just 10 rows in Item and 40 in Label. So my questions: Is it a fools errand to try to optimize this since the high cpu usage is due to the problems with the datastore or have I just screwed up somewhere in the code? ..fredrik

  • JConsole does not connect when a program (running in eclipse) is waiting for a console input

    - by Calm Storm
    Hi, I have a problem similar to the one mentioned here. I have a program which launches a selenium browser and refreshes it every 2 seconds. My idea here was to monitor the memory usage of my application as the page is being hit. This console program does a "System.in.read" and when a user presses enter key, this stops the browser refresh thread. I run the program and it runs as I would expect it to. But when I fire jconsole and attach it to the process, it looks like jconsole waits forever to attach. This is because of the "System.in.read", apparently as shown in the JConsole source. In my code it makes perfect sense for me to terminte the browser when user presses something so is there any alternative available at all ? (Posted code sample below) package com.ekanathk; import java.util.ArrayList; import java.util.List; import org.junit.Test; public class MultiThread { @Test public void testSimple() throws Exception { List<Integer> x = new ArrayList<Integer>(); for(int i = 0; i < 1000; i++) { x.add(i); } System.out.print("Press Enter to stop (try attach a jconsole now...."); System.in.read(); } } The problem here seems to be that any System.in.read (either in Main thread or any threads) seems to completely block jconsole. I guess the problem essentially boils down to multiple threads requesting system inputs at the same time? Is there a solution ? UPDATE 1: It seems this works fine when launching the class from a command line, however when I run from eclipse, jconsole cant connect. Any reasons ?

  • style problem with jQueryUI Autocomplete widget (using remote datasource)

    - by blee
    <input class="ui-autocomplete-input"/> represents the text field to be autocompleted. <ul>...</ul> contains the list of matching items from the text field input. It is added to the document by remote call as you type. <ul>...</ul> is added just inside the closing </body> tag. I was expecting the <ul>...</ul> to be placed just after the <input class="ui-autocomplete-input"/>. Because this does not happen, the <ul>...</ul> falls outside of the containing div and the resulting style is broken. Suggestions? Can I specify where the <ul>...</ul> gets placed in the document? Thanks in advance for your time.

  • Using VSTO in a standalone application to access Excel sheets

    - by chiccodoro
    Dear all, tried to research on that but sometimes I seem to lack some googling skills... I want to develop a (standalone) WinForms application which uses automation for communicating with Excel. I already know how to use the Interop, but I thought the VSTO tools would provide a more comfortable or sophisticated way to do that. My idea was: I could build a new standalone project with the excel references prepared. I could use a more sophisticated object model supplied by VSTO to communicate with Excel. However, my findings so far make me think that: VSTO can only be used to build add-ins/worksheets for Excel, not to build standalone application. There is no more sophisticated object model than the one provided by the Interop (which has such ugly things as a locale bug, a "Open(Missing, Missing, Missing...)" method and so on. I found a Worksheet and a Workbook class in the VSTO namespace, but as far as I understand it, these always refer to the CS classes for sheets and workbook which you implement when defining an Excel add-in or a workbook extension. - They cannot be used as comfortable wrappers in a standalone application. Can anybody confirm these statements or correct me where I am wrong? Further, if there should be a way to use VSTO and its "Workbook" class to load an excel workbook from a standalone application, then how do I do that? Thx, chiccodoro

  • Dojo 1.8: Getting dest.appendChild is not a function while rendering a custom template

    - by Jim Pedid
    After adding in the WidgetsInTemplateMixin, I am receiving an error dest.appendChild is not a function In the documentation, it claims that there will be an error if this.containerNode is not able to contain any child objects. However, I have marked the containerNode attachment point for a div with dojo type "dijit/layout/ContentPane". Can anyone explain to me why this isn't working? Here is the Template file <div class="${baseClass}"> <div class="${baseClass}Container" data-dojo-type="dijit/layout/BorderContainer" data-dojo-props="design: 'headline'"> <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region: 'top'"> Top </div> <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region: 'center'" data-dojo-attach-point="containerNode"> </div> <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region: 'leading', splitter: true"> Sidebar </div> </div> </div> Here is the javascript definition define([ "dojo/_base/declare", "dijit/_WidgetBase", "dijit/_OnDijitClickMixin", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dijit/layout/TabContainer", "dijit/_TemplatedMixin", "dijit/_WidgetsInTemplateMixin", "dojo/text!./templates/MainContainer.html" ], function (declare, _WidgetBase, _OnDijitClickMixin, BorderContainer, ContentPane, TabContainer, _TemplatedMixin, _WidgetsInTemplateMixin, template) { return declare([_WidgetBase, _OnDijitClickMixin, _TemplatedMixin, _WidgetsInTemplateMixin], { templateString:template, baseClass:"main" }); }); The custom widget defined declaratively <div data-dojo-type="main/ui/MainContainer" data-dojo-props="title: 'Main Application'"> Hello Center! </div>
