  • cakephp routing problem, plugin routing works but not others

    - by Paul
    I'm having a strange routing problem with a site I just uploaded, and I've made a number of changes to test what's happening. It doesn't make any sense. My setup is: - I'm using one plugin, which I've included all the routing in the routes.php file. - I've also included the routes for two other controllers, 'events' and 'updates' they look like this: Router::connect('/login', array('plugin' = 'pippoacl', 'controller' = 'users', 'action' = 'login')); Router::connect('/logout', array('plugin' = 'pippoacl', 'controller' = 'users', 'action' = 'logout')); Router::connect( '/events/', array( 'controller' = 'events', 'action' = 'index')); Router::connect('/updates', array('controller' = 'updates', 'action' = 'index')); What happens when I try to get to 'events' is that I get an error message saying: "Not Found Error: The requested address '/Events' was not found on this server." I've checked the database and it's accessible, through the plugin's model/controller/view. I've also made sure the model/controllers for 'events' and 'updates' are there. Can anyone tell me how to trouble shoot this? Thanks, Paul

  • How do you handle 'SelectedItemChanged' events in a MVVM ViewModel?

    - by Travis
    I have some logic that depends upon two properties being set, as it executes when both properties have a value. For example: private void DoCalc() { if (string.IsNullOrEmpty(Property1) || string.IsNullOrEmpty(Property2)) return; Property3 = Property1 + " " + Property2; } That code would need to be executed every time Property1 or Property2 changed, but I'm having trouble figuring out how to do it in a stylistically acceptable manner. Here are the choices as I see them: 1) Call method from ViewModel I don't have a problem with this conceptually, as the logic is still in the ViewModel - I'm not a 'No code-behind' nazi. However, the 'trigger' logic (when either property changes) is still in the UI layer, which I don't love. The codebehind would look like this: void ComboBox_Property1_SelectedItemChanged(object sender, RoutedEventArgs e) { viewModel.DoCalc(); } 2) Call method from Property Setter This approach seems the most 'pure', but it also seems ugly, as if the logic is hidden. It would look like this: public string Property1 { get {return property1;} set { if (property1 != value) { property1 = value; NotifyPropertyChanged("Property1"); DoCalc(); } } } 3) Hook into the PropertyChanged event I'm now thinking this might be the right approach, but it feels weird to hook into the property changed event in the implementing viewmodel. It would look something like this: public ViewModel() { this.PropertyChanged += new PropertyChangedEventHandler(ViewModel_PropertyChanged); } void ViewModel_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "Property1" || e.PropertyName == "Property2") { DoCalc(); } } So, my question is, if you were browsing through some source code with that requirement, which approach would you prefer to see implemented (and why?). Thanks for any input.

  • Flash Builder missing fundamental things

    - by Bart van Heukelom
    All of a sudden Flash Builder 4 is missing all kinds of fundamental things and is generating incorrect errors. I've had the same issue yesterday, where I fixed it by downloading a new Flex SDK and importing that into FB. I did this again, but this time it fixed nothing. I don't think it's something I did, like removing critical references from the build path. The errors also appeared on projects I was not working on at the time. It occurs for ActionScript, Flex and Flex Library projects alike. Update: I find this stack trace in the Flash Builder error log: !ENTRY com.adobe.flexbuilder.project 4 43 2010-05-11 11:55:47.495 !MESSAGE Uncaught exception in compiler !STACK 0 java.lang.NullPointerException at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2592) at macromedia.asc.parser.VariableBindingNode.evaluate(VariableBindingNode.java:64) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2233) at macromedia.asc.parser.ListNode.evaluate(ListNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2578) at macromedia.asc.parser.VariableDefinitionNode.evaluate(VariableDefinitionNode.java:48) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2503) at macromedia.asc.parser.WithStatementNode.evaluate(WithStatementNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2891) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2905) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3643) at macromedia.asc.parser.ClassDefinitionNode.evaluate(ClassDefinitionNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3371) at macromedia.asc.parser.ProgramNode.evaluate(ProgramNode.java:80) at flex2.compiler.as3.As3Compiler.analyze4(As3Compiler.java:709) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:3089) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:2977) at flex2.compiler.CompilerAPI.batch2(CompilerAPI.java:528) at flex2.compiler.CompilerAPI.batch(CompilerAPI.java:1274) at flex2.compiler.CompilerAPI.compile(CompilerAPI.java:1496) at flex2.tools.oem.Application.compile(Application.java:1188) at flex2.tools.oem.Application.recompile(Application.java:1133) at flex2.tools.oem.Application.compile(Application.java:819) at flex2.tools.flexbuilder.BuilderApplication.compile(BuilderApplication.java:344) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder$MyBuilder.mybuild(ASApplicationBuilder.java:276) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder.build(ASApplicationBuilder.java:127) at com.adobe.flexbuilder.multisdk.compiler.internal.ASBuilder.build(ASBuilder.java:190) at com.adobe.flexbuilder.multisdk.compiler.internal.ASItemBuilder.build(ASItemBuilder.java:74) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.buildItem(FlexProjectBuilder.java:480) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.build(FlexProjectBuilder.java:306) at com.adobe.flexbuilder.project.compiler.internal.FlexIncrementalBuilder.build(FlexIncrementalBuilder.java:157) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

  • How to assign RelayCommand to Click or SelectedIndexChanges events?

    - by Hikari
    Hello, I'm just starting with MVVM light, but so far it allowed me to solve some of my issues. Infortunately I'm struggling with relatively sime issues in Silverlight. Let's assume the following button with EventToCommand: <i:Interaction.Triggers> <i:EventTrigger EventName="MouseEnter"> <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding UpdateAccountsCommand, Mode=OneWay}" CommandParameter="{Binding SelectedIndex, ElementName=lstLedgers}"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> How to assign this code to SelectedIndexChanged event? Futher issue - how to assign a command in C# code? The problem is as follows: I'm developing Windows Phone 7 app. Application Bar needs to be initiated in C# (as far as I know there is no xaml code for application bar at this stage). As a result I have no idea how to bind a command to a application bat button in from c#, now xaml. Thanks in advance your your help.

  • Do Android/webOS devices support multi-touch Javascript events?

    - by Rufo Sanchez
    On iPhone, iPod touch and (presumably) iPad, Apple has multi-touch event handling available via JavaScript in Mobile Safari. I know the Nexus One recently added multi-touch support via an update, and I believe webOS is also multi-touch enabled. Do Android 2.1 and/or webOS have access to multi-touch in the browser, or is this currently exclusive to Apple devices?

  • How to intercept touches events on a MKMapView or UIWebView objects?

    - by Martin
    Hello, I'm not sure what i'm doing wrong but I try to catch touches on a MKMapView object. I subclassed it by creating the following class : #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewWithTouches : MKMapView { } - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event; @end And the implementation : #import "MapViewWithTouches.h" @implementation MapViewWithTouches - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event { NSLog(@"hello"); //[super touchesBegan:touches withEvent:event]; } @end But it looks like when I use this class, I see nothing on the Console : MapViewWithTouches *mapView = [[MapViewWithTouches alloc] initWithFrame:self.view.frame]; [self.view insertSubview:mapView atIndex:0]; Any idea what I'm doing wrong? Heelp! :) Thanks a lot! Martin

  • iPad Gestures. How Do I Force a Child View to Discard Gesture Events.

    - by dugla
    On iPad, I have a parent-child view hierarchy. The parent is a fullscreen EAGLView and the child is a UIToobar. The parent has pan/touch/pinch gesture recognizers attached. When gestures occur on the child (toolbar) they are passed on to the parent (fullscreen view). Not what I want. How do I force the toolbar to discard/ignore gestures? Thanks, Doug

  • Is it okay to programmatically create UITouch and UIEvent objects to emulate touch events?

    - by mystify
    I want to simulate some touches on my UI, without using private API. So one simple way to do it is to simply call those -touchesBegan:withEvent:, -touchesMoved:withEvent:, -touchesEnded:WithEvent: and -touchesCancelled:withEvent: methods inside my custom controls. For that, I would have to create UITouch and UIEvent dummy objects with appropriate data inside. Is this fine with them? Or would they reject my app?

  • How to create a run loop that only listens to performSelector:onThread: and GUI events?

    - by Paperflyer
    I want to create a separate thread that runs its own window. Frankly, the documentation does not make sense to me. So I create an NSThread with a main function. I start the thread, create an NSAutoreleasePool, and run the run loop: // Global: BOOL shouldKeepRunning = YES; - (void)threadMain { NSAutoreleasePool *pool = [NSAutoreleasePool new]; // Load a nib file, set up its controllers etc. while (shouldKeepRunning) { NSAutoreleasePool *loopPool = [NSAutoreleasePool new]; [[NSRunLoop currentRunLoop] runUntilDate:[NSDate distantFuture]]; [loopPool drain]; } [pool drain]; } But since there is no registered port or observer, runUntilDate: exits immediately and CPU utilization goes to 100%. All thread communication is handled by calls to performSelector:onThread:withObject:waitUntilDone:. Clearly, I am not using the API correctly. So, what am I doing wrong?

  • is it legal/ethical to use source code provided in academic papers, or talks given at trade events l

    - by lucid
    so, is it legal to use source code from papers and such: like this paper on perlin noise: [url]http://mrl.nyu.edu/~perlin/paper445.pdf[/url] links to this source code: [url]http://mrl.nyu.edu/~perlin/noise/[/url] and stam's famous talk on fluid dynamics, includes source code throughout, annotated with instructions like "add these macros to the beginning of your code" [url]http://www.dgp.toronto.edu/people/stam/reality/Research/pdf/GDC03.pdf[/url] I'm just not sure if it's legal to copy and paste this to use in your own commercial code. if I were to make my own implementation, it would end up being close to identical, since I'd probably use the source code as a reference. I know very little about copyright law, including how it applies in these situations, and I can never find usage and licensing terms for these. Nor did googling any terms I could think of provide me the specific answer I need. does anyone know for sure what the rules/laws are here, or where I can find the answer?

  • How to recognize touch events and control a script object inside UIWebView?

    - by Markus S.
    Situation: I have an UIView with an UIWebView in it. When the viewDidLoad the Javascript Object inside the UIWebView is called (Microsoft Seadragon AJAX JS). For your Understanding: Seadragon loads a specified megapixel image(JPEG) and in a Desktop Browser like Firefox i can Zoom into the image and I can drag the crop for example from the middle to the left. In the iPhone Simulator (for iPad) only the Zooming Function is working on one single tap but when i try to drag the crop (with left mouse button click and holding it) I'm dragging the whole UIWebView but not the crop of course! Is that feature which the simulator isn't able to handle or what's yout solutin guys? Special Thanks!! P.S.: It's a bit jiggling when the zooming function of Seadragon is called. Is that authentic to the real performance of the iPad or does the simulator not have the power as the iPad has?

  • How to Detect Forward and Back Mouse Button Events in Delphi?

    - by EagleOfToledo
    If a mouse has other buttons in addition to the standard left/right/middle (e.g. forward/back), how can we detect those button clicks in Delphi? An example of how this is used is the Internet Explorer, where the forward/back button on the side of a Logitech or MS mouse cycles forward and back between any loaded web pages. This seems to replicate the Backspace/CTRL+Backspace on the keyboard but I tried to detect that using KeyPreview and the KeyPress event but it does not pick it up. Any idea how to detect clicks on these extended mouse buttons?

  • Why does Visual Studio sometimes add a number when creating page events in codebehinds?

    - by Kevin Pang
    When writing up a codebehind in Visual Studio for ASP.NET web forms applications, I often use the dropdowns at the top of the window to autogenerate page event handlers (e.g. Page_Load, Page_PreRender). I've noticed that sometimes Visual Studio likes to add numbers to these function names like "Page_Load1" or "Page_PreRender2". Programatically speaking, this has no effect on the code. But stylistically, I find it a bit ugly. Is there any way to get rid of this behavior?

  • Add JSON support to Rails app

    - by Meltemi
    I am experimenting with Rails and was wondering what's needed to allow/add support for JSON requests? I have a vanilla installation of Rails 2.3.5 and the default scaffolding seem to provide support for HTML & XML requests but not JSON. class EventsController < ApplicationController # GET /events # GET /events.xml def index @events = Event.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @events } end end # GET /events/1 # GET /events/1.xml def show @event = Event.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @event } end end ... I'm new to this but it would appear as though i would need to add a format line in each method along the lines of: format.js { render :js => @event.json } couldn't this be done automatically? perhaps there's a template somewhere i need to update...or a flag i can set? Or perhaps, and most likely, I've missed the boat entirely?!?

  • Any good books out there for advanced concepts like lambdas, delegates, events etc?

    - by they_soft
    I've read about these features but I don't think I've seen enough to consistently apply them in my coding, eg "This would be better done with a delegate than with my other, outdated approach". I know what they do, but I want more examples of use cases, or want some heuristic to help me think in terms of such features. All the books I've seen either focus only on the basics or just mention the features as part of the language. Is there any book out there that deals with this? Preferably C# or language agnostic.

  • What are the basics of dealing with user input events in Android?

    - by user279112
    Hello. I thought I had understood this question, but something is quite wrong here. When the user (me, so far) tries to press keys, nothing really happens, and I am having a lot of trouble understanding what it is that I've missed. Consider this before I present some code to help clarify my problem: I am using Android's Lunar Lander example to make my first "real" Android program. In that example, of course, there exist a class LunarView, and class nested therein LunarThread. In my code the equivalents of these classes are Graphics and GraphicsThread, respectively. Also I can make sprite animations in 2D just fine on Android. I have a Player class, and let's say GraphicsThread has a Player member referred to as "player". This class has four coordinates - x1, y1, x2, and y2 - and they define a rectangle in which the sprite is to be drawn. I've worked it out so that I can handle that perfectly. Whenever the doDraw(Canvas canvas) method is invoked, it'll just look at the values of those coordinates and draw the sprite accordingly. Now let's say - and this isn't really what I'm trying to do with the program - I'm trying to make the program where all it does is display the Player sprite at one location of the screen UNTIL the FIRST time the user presses the Dpad's left button. Then the location will be changed to another set position on the screen, and the sprite will be drawn at that position for the rest of the program invariably. Also note that the GraphicsThread member in Graphics is called "thread", and that the SurfaceHolder member in GraphicsThread is called "mSurfaceHolder". So consider this method in class Graphics: @Override public boolean onKeyDown(int keyCode, KeyEvent msg) { return thread.keyDownHandler(keyCode, msg); } Also please consider this method in class GraphicsThread: boolean keyDownHandler(int keyCode, KeyEvent msg) { synchronized (mSurfaceHolder) { if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) { player.x1 = 100; player.y1 = 100; player.x2 = 120; player.y2 = 150; } } return true; } Now then assuming that player's coordinates start off as (200, 200, 220, 250), why won't he do anything different when I press Dpad: Left? Thanks!

    Hi All, I'm trying to define some default behaviours for my jQuery Dialogs like the following: (function($) { /** * Overriding default options **/ $.ui.dialog.defaults.bgiframe = true; $.ui.dialog.defaults.open = function() { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','hidden'); $('html').css('overflow-x','hidden'); } else { // disable scrollbar for other browsers $('body').css('overflow','hidden'); } }; $.ui.dialog.defaults.beforeclose = function(event, ui) { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','auto'); $('html').css('overflow-x','auto'); } else { // disable scrollbar for other browsers $('body').css('overflow','auto'); } }; })(jQuery); The above works when I have no custom open/beforeclose function specified when the dialog is created. So I'm wondering what is the best practice to add these functionality into all my dialogs, while preserving the ability to specify open/beforeclose functions.

  • PHP MVC Framework Structure

    - by bigstylee
    I am sorry about the amount of code here. I have tried to show enough for understanding while avoiding confusion (I hope). I have included a second copy of the code at Pastebin. (The code does execute without error/notice/warning.) I am currently creating a Content Management System while trying to implement the idea of Model View Controller. I have only recently come across the concept of MVC (within the last week) and trying to implement this into my current project. One of the features of the CMS is dynamic/customisable menu areas and each feature will be represented by a controller. Therefore there will be multiple versions of the Controller Class, each with specific extended functionality. I have looked at a number of tutorials and read some open source solutions to the MVC Framework. I am now trying to create a lightweight solution for my specific requirements. I am not interested in backwards compatibility, I am using PHP 5.3. An advantage of the Base class is not having to use global and can directly access any loaded class using $this->Obj['ClassName']->property/function();. Hoping to get some feedback using the basic structure outlined (with performance in mind). Specifically; a) Have I understood/implemented the concept of MVC correctly? b) Have I understood/implemented Object Orientated techniques with PHP 5 correctly? c) Should the class propertise of Base be static? d) Improvements? Thank you very much in advance! <?php /* A "Super Class" that creates/stores all object instances */ class Base { public static $Obj = array(); // Not sure this is the correct use of the "static" keyword? public static $var; static public function load_class($directory, $class) { echo count(self::$Obj)."\n"; // This does show the array is getting updated and not creating a new array :) if (!isset(self::$Obj[$class]) && !is_object(self::$Obj[$class])) //dont want to load it twice { /* Locate and include the class file based upon name ($class) */ return self::$Obj[$class] = new $class(); } return TRUE; } } /* Loads general configuration objects into the "Super Class" */ class Libraries extends Base { public function __construct(){ $this->load_class('library', 'Database'); $this->load_class('library', 'Session'); self::$var = 'Hello World!'; //testing visibility /* Other general funciton classes */ } } class Database extends Base { /* Connects to the the database and executes all queries */ public function query(){} } class Session extends Base { /* Implements Sessions in database (read/write) */ } /* General functionality of controllers */ abstract class Controller extends Base { protected function load_model($class, $method) { /* Locate and include the model file */ $this->load_class('model', $class); call_user_func(array(self::$Obj[$class], $method)); } protected function load_view($name) { /* Locate and include the view file */ #include('views/'.$name.'.php'); } } abstract class View extends Base { /* ... */ } abstract class Model extends Base { /* ... */ } class News extends Controller { public function index() { /* Displays the 5 most recent News articles and displays with Content Area */ $this->load_model('NewsModel', 'index'); $this->load_view('news', 'index'); echo $this->var; } public function menu() { /* Displays the News Title of the 5 most recent News articles and displays within the Menu Area */ $this->load_model('news/index'); $this->load_view('news/index'); } } class ChatBox extends Controller { /* ... */ } /* Lots of different features extending the controller/view/model class depending upon request and layout */ class NewsModel extends Model { public function index() { echo $this->var; self::$Obj['Database']->query(/*SELECT 5 most recent news articles*/); } public function menu() { /* ... */ } } $Libraries = new Libraries; $controller = 'News'; // Would be determined from Query String $method = 'index'; // Would be determined from Query String $Content = $Libraries->load_class('controller', $controller); //create the controller for the specific page if (in_array($method, get_class_methods($Content))) { call_user_func(array($Content, $method)); } else { die('Bad Request'. $method); } $Content::$var = 'Goodbye World'; echo $Libraries::$var . ' - ' . $Content::$var; ?> /* Ouput */ 0 1 2 3 Goodbye World! - Goodbye World
