  • CodeIgniter helper inside controllers

    - by kapitanluffy
    can i call helper functions inside controller classes? let's say i have this controller with the _open_form method class User extends Controller { function _open_form($action){ print_r(form_open($action)); } } i tried echoing out the result of form_open() but it returns null. it seems that helper functions can't be called inside controllers if your wondering why i need to use it inside the controller instead in the view because we are required to use the given template parser xD

  • Sorting function/variables in an object by name

    - by sissonb
    I was wondering if PHPStorm by Jetbrains has a tool to sort the methods in my JavaScript object by name. If not are there any other tools that can do this for me? Ext.regController("dashboard", { goToShoppingCart:function() { Ext.dispatch({ controller:"shoppingCart", action:"loadCart" }); }, goToDashboard:function() {}, goToContact:function() {} } ); to Ext.regController("dashboard", { goToContact:function() {}, goToDashboard:function() {}, goToShoppingCart:function() { Ext.dispatch({ controller:"shoppingCart", action:"loadCart" }); } } ); This is only for organization. Thanks

  • Learning PHP: Good examples of "build-this" based lessons?

    - by DavidR
    Last summer I learned HTML and CSS for a job, mainly through tutorials and a sort of "build this" method, that is, I'm given a goal and have to try to figure out how to build it myself. Is there a place with some examples to teach someone with this method? My boss wants to get me going on PHP this summer, and I need to refamiliarize myself with it over the next week. Most people send me to Php.net to follow the documentation, is there another good method out there?

  • How to get an object from a list based upon IEqualityComparer<T>

    - by Greg
    The Compare method in Linq lets you find by an IEqualityComparer, but I can't find a counterpart method that allows you retrieve an item by the same comparer. Is this really the best way to do it? MyItem myFinderItem = new MyItem(keyField1, keyField2); if (myList.Contains(myFinderItem, new MyEqualityComparer())) { MyItem myRealItem = myList.Single(item => new MyEqualityComparer().Equals(item , myFinderItem)); } (I'm sharing the usage of the IEqualityComaprer with a call to the Except Linq method and I'd like to maintain a single source for equality comparisons)

  • use viewengine only within certain area

    - by Daniel Powell
    Is it possible to use a custom view engine for a specific area only? I have tried public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Forms_default", "Forms/{client}/{controller}/{action}/{id}", new { client="Generic",action = "Index", id = UrlParameter.Optional } ); ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new ClientSpecificViewEngine()); } Within my area but this seems to be a site wide affect as I'm getting errors specific to the custom view engine when visiting pages outside the area.

  • Testing file existence using NSURL

    - by Peter Hosey
    Snow Leopard introduced many new methods to use NSURL objects to refer to files, not pathnames or Core Services' FSRefs. However, there's one task I can't find a URL-based method for: Testing whether a file exists. I'm looking for a URL-based version of -[NSFileManager fileExistsAtPath:]. Like that method, it should return YES if the URL describes anything, whether it's a regular file, a directory, or anything else. I could attempt to look up various resource values, but none of them are explicitly guaranteed to not exist if the file doesn't, and some of them (e.g., NSURLEffectiveIconKey) could be costly if it does. I could just use NSFileManager's fileExistsAtPath:, but if there's a more modern method, I'd prefer to use that. Is there a simple method or function in Cocoa, CF, or Core Services that's guaranteed/documented to tell me whether a given file (or file-reference) URL refers to a file-system object that exists?

  • Java: easiest way to package both Java 1.5 and 1.6 code

    - by WizardOfOdds
    I want to package a piece of code that absolutely must run on Java 1.5. There's one part of the code where the program can be "enhanced" if the VM is an 1.6 VM. Basically it's this method: private long[] findDeadlockedThreads() { // JDK 1.5 only supports the findMonitorDeadlockedThreads() // method, so you need to comment out the following three lines if (mbean.isSynchronizerUsageSupported()) return mbean.findDeadlockedThreads(); else return mbean.findMonitorDeadlockedThreads(); } What would be easiest way to have this compile on 1.5 and yet do the 1.6 method calls when on 1.6 ? In the past I've done something similar by compiling a unique 1.6 class that I would package with my app and instantiate using a ClassLoader when on 1.6 (because an 1.6 JVM is perfectly fine mixing 0x32 and 0x31 classes), but I think it's a bit overkill (and a bit painful because during the build process you have to build both 0x31 and 0x32 .class files). How should I go if I wanted to compile the above method on 1.5? Maybe using reflection but then how (I'm not familiar at all with reflection) Note: if you're curious, the above method comes from this article: http://www.javaspecialists.eu/archive/Issue130.html (but I don't want to "comment the three lines" like in the article, I want this to compile and run on both 1.5 and 1.6)

  • HelloWebView Sample: now using SDK 3 and getting killed

    - by Tim
    Hey Folks, Well I was trying to get the HelloWebview example working with SDK 7 with no success (see HelloWebView Sample: java.lang.SecurityException: Permission Denial thread), so I decided just out of curiosity to back off to SDK3 to see if I could learn anything. I have been able to get all the "Layout" samples to work and decided to try something a little harder. Unfortunately, I still cannot get the simple HelloWebView app to run. I no longer get a Permission Denial but now the app is getting killed. Killed usually implies that there are not enough resources (memory etc.) for an application to run.... Any thoughts? Are there any other log files I can look at either on my computer or on the emulator? The main.xml, manifest, and console output are below. Let me know if you need more information. Thanks, Tim main.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </LinearLayout> mainfest file: <uses-permission android:name="android.permission.INTERNET" /> <uses-sdk android:minSdkVersion="3" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".HelloWebView3" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".HelloWebView3" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar"> </activity> </application> Console output: [2010-06-05 08:43:37 - HelloWebView3] ------------------------------ [2010-06-05 08:43:37 - HelloWebView3] Android Launch!

How can I get admin rights on-demand in a .NET application?

  • Start thread with two parameters

    - by Matt
    I've got a method that gets called on an event, which presents me with two variables varA, varB (both strings). This method gets called with new information quite frequently, thus I have created a separate method that takes in the two parameters. I want to run this method in a thread, however have struck the issue that Thread.Start will not accept parameters. I've tried a few supposed methods, but have so far had no luck.. I think my best bet is to create a separate class, and handle it there.. However I have a List which I am inserting data into, and hit a dead end when the separate class tried to access that list, since it was in a different class. Can someone help me out here please?

  • Can extension methods be applied to interfaces?

    - by Greg
    Hi, Is it possible to apply an extension method to an interface? (C# question) That is for example to achieve the following: create an ITopology interface create an extension method for this interface (e.g. public static int CountNodes(this ITopology topologyIf) ) then when creating a class (e.g. MyGraph) which implements ITopology, then it would automatically have the Count Nodes extension. This way the classes implementing the interface would not have to have a set class name to align with what was defined in the extension method.

  • Objects in interface

    - by Peter Kowalchuk
    I created my own object, PKSurvey. In the interface of the View Controller I can define a pointer to it, then in a method I can alloc it and have an instance. How do I keep the instance beyond the method where it was allocated? I assign values in one method and want to be able to use those values in other methods. Should I allocate it in the viewDidLoad method or should I do it somewhere else? @interface DIrectionalDrillerViewController : UIViewController { PKSurvey *Survey=[PKSurvey new]; ---------------- - (void)viewDidLoad { [Survey new];
