  • JQuery going through a set of UL and dynamically set ids incremently on each one

    - by Calibre2010
    I have an unordered list which contains serveral items called 'oListItems' the UL has a class but no id. The class OuteroListItems contains many of oListitems oList.AppendFormat("<ul class='OuteroListItems'>"); oList.AppendFormat("<li>"); oList.AppendFormat("<ul class='oListItems'>"); oList.AppendFormat("<li>" + s.sName + "</li>"); oList.AppendFormat("<li>" + s.eName + "</li>"); oList.AppendFormat("<li>" + s.SDate + "</li>"); oList.AppendFormat("<li>" + s.EDate + "</li>"); oList.AppendFormat("</ul>"); oList.AppendFormat("</li>"); oList.AppendFormat("</ul>"); I want for each .oListItem class that gets retrieved, add dynamically an id to it. var o = $(".oListItem"); $.each(o, function (){ var f = $(this).attr("id", 'listItem' + i); i++; }); wasent sure on the approach, this is what I have so far?

  • Why does the VS2005 debugger not report "base." values properly? (was "Why is this if statement fail

    - by Rawling
    I'm working on an existing class that is two steps derived from System.Windows.Forms.Combo box. The class overrides the Text property thus: public override string Text { get { return this.AccessibilityObject.Value; } set { if (base.Text != value) { base.Text = value; } } } The reason given for that "get" is this MS bug: http://support.microsoft.com/kb/814346 However, I'm more interested in the fact that the "if" doesn't work. There are times where "base.Text != value" is true and yet pressing F10 steps straight to the closing } of the "set" and the Text property is not changed. I've seen this both by just checking values in the debugger, and putting a conditional breakpoint on that only breaks when the "if" statement's predicate is true. How on earth can "if" go wrong? The class between this and ComboBox doesn't touch the Text property. The bug above shouldn't really be affecting anything - it says it's fixed in VS2005. Is the debugger showing different values than the program itself sees? Update I think I've found what is happening here. The debugger is reporting value incorrectly (including evaluating conditional breakpoints incorrectly). To see this, try the following pair of classes: class MyBase { virtual public string Text { get { return "BaseText"; } } } class MyDerived : MyBase { public override string Text { get { string test = base.Text; return "DerivedText"; } } } Put a breakpoint on the last return statement, then run the code and access that property. In my VS2005, hovering over base.Text gives the value "DerivedText", but the variable test has been correctly set to "BaseText". So, new question: why does the debugger not handle base properly, and how can I get it to?

  • C# - Making fields/properties read only conditionally

    - by Alistair77
    I have three classes; Classes A and B both reference class C. How can I make it so members of class C can be modified when referenced from class A but not modified when referenced from class B? IE, the following should be possible; classA myClassA = new classA(); myClassA.myClassC.IssueNumber = 3; But this should not be possible; classB myClassB = new classB(); myClassB.myClassC.IssueNumber = 3; Making classB.classC read-only still allows properties of classC to be altered. I'm sure this is basic stuff but can't find a simple answer. Thanks, A

  • How to know if a std::list has been modified

    - by Nick
    I have this class: class C { public: C* parent; std::list<C> children; }; I can use this class in this way for example: C root; C child; root.children.push_back(child); // or other method of std::list (es: push_front, insert, ...) // Here child.parent is root // How can I set the parent of child? I want to do this work internally to my class without losing the functionality of std::list, is it possible?

  • Find all radio groups which haven't been selected

    - by nickf
    I have a basic quiz/survey type application I'm working on, and I'd like to give the user a prompt before they submit if they haven't answered all the questions. All the questions are multiple choice using radio buttons: <div class="question"> Q1: What is the second letter of the alphabet? <div class="choices"> <input type="radio" name="question_1" value="1" /> A <input type="radio" name="question_1" value="2" /> B <input type="radio" name="question_1" value="3" /> C </div> </div> <div class="question"> Q2: Which out of these is a berry? <div class="choices"> <input type="radio" name="question_2" value="1" /> Apples <input type="radio" name="question_2" value="2" /> Bananas <input type="radio" name="question_2" value="3" /> Carrots </div> </div> <div class="question"> ...etc How do you find which groups haven't got an option ticked? Or at least, if there are any which haven't been answered? jQuery is ok, and even preferred.

  • Do I always need to rebuild the project containing references to sub project's dll, if sub projects

    - by Puneet Dudeja
    I have a solution containing 4 class library projects and one "web site" project. The web site project contains references to the 3 class library projects, whenever I make changes in any of the class library projects, the only option I see is to rebuild the web site which takes a lot of time. Is there any option that I can only update the dll references and the changes are reflected in the web site project ?

  • Listening to PHP function calls to intercept the returned value

    - by Lansen Q
    I am working on making use of a Web Services API offered by the hosts of our internal system. I am accessing it via PHP with the built-in SOAP offering. The API session is initiated by a remote call to a function that returns some session tokens; every call to any function thereafter will return a new session token, which must accompany the next request. I have an API Client class that is doing the bulk of the work; what I would like to do is to set something up whereby any SOAP call that is made will make sure to update the API Client class' $session variable with the new session details, and then pass the data along. So far the only way I can think of doing this is creating a new class extending the SoapClient class, with a __call function wrapper to execute the function, update the new session token, and return the results nonetheless. I'm not sure that this will a) work b) be the best way to go about this. The wrapper class would be identical to making a SOAP call, and it would return an identical result, just it would update the session token before you get your result back. Thanks! Hope I explained myself properly.

  • Is there a way to deserialize an object into "$this"?

    - by Andreas Bonini
    I'm writing a class to handle a memcached object. The idea was to create abstract class Cachable and all the cachable objects (such as User, Post, etc) would be subclasses of said class. The class offers some method such as Load() which calls the abstract function LoadFromDB() if the object is not cached, functions to refresh/invalidate the cache, etc. The main problem is in Load(); I wanted to do something similar: protected function Load($id) { $this->memcacheId = $id; $this->Connect(); $cached = $this->memcache->get(get_class($this) . ':' . $id); if($cached === false) { $this->SetLoaded(LoadFromDB($id)); UpdateCache(); } else { $this = $cached; $this->SetLoaded(true); } } Unfortunately I need $this to become $cached (the cached object); is there any way to do that? Was the "every cachable object derives from the cachable class" a bad design idea?

  • Simultaneous private and public inheritance in C++

    - by gspr
    Suppose a class Y publicly inherits a class X. Is it possible for a class Z to privately inherit Y while publicly inheriting X? To make this clearer, suppose X defines public methods x1 and x2. Y inherits X, overrides x1 and provides a method y. Does C++ allow for a third class Z to subclass Y in such a way that Y's implementation of x1 and y are privately available to it, while the outside world only sees it inheriting X publicly, i.e. having only a single public method x2?

  • allocator with no template

    - by Merni
    Every stl container take an allocator as a second object, template < class T, class Allocator = allocator<T> > class vector; If you write your own class It is possible to use your own allocator. But is it possible to write your own allocator without using templates? For example, writing this function is not easy if you are not allowed to use templates pointer allocate(size_type n, const_pointer = 0) { void* p = std::malloc(n * sizeof(T)); if (!p) throw std::bad_alloc(); return static_cast<pointer>(p); } Because how could you know the size of T?

  • Protect value from changies using reflection?

    - by IordanTanev
    Hi, here is the problem case i am writing a little third party library. In this library i have a class like this public class TestClass { public int TestField { get; private set; } public TestClass( ) { TestField = 1; } } Then i have a varialbe form this class like this public TestClass test = new TestClass( ); The problem i am facing is that usnig reflection like this PropertyInfo field = typeof( TestClass ).GetProperty( "TestField" ); field.SetValue( test, 2, null ); programers can change internal value of this class. this will be very bad thing becouse it can crash the hole library. My question is what is the best way to protect my code form such changes.I know i can use some kind of bool flag so tha value can be changed only ones but this is not very good salution is there a better one? Best Regards, Iordan

  • Creating a library of classes in php - how to handle the library root location?

    - by jax
    I am about to create a collection of classes in php which are interrelated. Now I would like to include files using their absolute path, ie If I were in '/com/mysite/licences/Generator.class.php' I would like to include files like this: include '/com/mysite/lib/Utils.class.php' I don't want to include like this, I think it is confusing and ugly include '../licenses/Utils.class.php' This works ok, unless 'com' is not in the root of public_html. I assume I will need some sort of prefix to append to each file LIBRARY_ROOT that hold the location of 'com' in the current filesystem. So it might look like this include LIBRARY_ROOT.'com/mysite/lib/Utils.class.php' What is the best way to do this?

There's a .dll.intermediate.manifest file, but no .dll. So wut I did wrong?

  • C# xml serializer - serialize derived objects

    - by gln
    Hi, I want to serialize the following: [Serializable] [DefaultPropertyAttribute("Name")] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfo { private string name; [XmlArray("Items"), XmlArrayItem(typeof(ItemInfo))] private ArrayList arr; private ItemInfo parentItemInfo; } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoA : ItemInfo { ... } [Serializable] [XmlInclude(typeof(ItemInfo))] [XmlInclude(typeof(ItemInfoA))] [XmlInclude(typeof(ItemInfoB))] public class ItemInfoB : ItemInfo { ... } The class itemInfo describes a container which can hold other itemInfo objects in the array list, the parentItemInfo describes which is the parent container of the item info. Since ItemInfoA and ItemInfoB derive from ItemInfo they can also be a member of the array list and the parentItemInfo, therefore when trying to serialize these objects (which can hold many objects in hierarchy) it fails with exception can't generate the xml file - innerexception. My question is: What attributes do I need to add the ItemInfo class so it will be serializable? Note: the exception is only when the ItemInfo[A]/[B] are initialized with parentItemInfo or the arrayList. Help please! Thanks!

  • How to save to two tables using one SQLAlchemy model

    - by Oatman
    I have an SQLAlchemy ORM class, linked to MySQL, which works great at saving the data I need down to the underlying table. However, I would like to also save the identical data to a second archive table. Here's some psudocode to try and explain what I mean my_data = Data() #An ORM Class my_data.name = "foo" #This saves just to the 'data' table session.add(my_data) #This will save it to the identical 'backup_data' table my_data_archive = my_data my_data_archive.__tablename__ = 'backup_data' session.add(my_data_archive) #And commits them both session.commit() Just a heads up, I am not interested in mapping a class to a JOIN, as in: http://www.sqlalchemy.org/docs/05/mappers.html#mapping-a-class-against-multiple-tables

  • Debug.writeline locks

    - by Carra
    My program frequently stops with a deadlock. When I do a break-all and look at the threads I see that three threads are stuck in our logging function: public class Logging { public static void WriteClientLog(LogLevel logLevel, string message) { #if DEBUG System.Diagnostics.Debug.WriteLine(String.Format("{0} {1}", DateTime.Now.ToString("HH:mm:ss"), message)); //LOCK #endif //...Log4net logging } } If I let the program continue the threads are still stuck on that line. I can't see where this can lock. The debug class, string class & datetime class seem to be thread safe. The error goes away when I remove the "#if DEBUG System... #endif" code but I'm curious why this behavior happens. Thread one: public void CleanCache() { Logging.WriteClientLog(LogLevel.Debug, "Start clean cache.");//Stuck } Thread two: private void AliveThread() { Logging.WriteClientLog(LogLevel.Debug, "Check connection");//Stuck }

  • Where do you put non-controller classes in codeigniter?

    - by sprugman
    I've got a class Widgets. Widgets are made up of Doohickies. I'm never going to need to access Doohickies directly via url -- they're essentially a private class, only used by Widgets. Where do you put your code to define the Doohicky class? In /app/controllers/doohicky.php? in app/controllers/widget.php? somewhere else? Obviously, the former seems cleaner, but it's not obvious to me how to make the Doohicky class available to Widget.

  • How to test Guice Singleton?

    - by 01
    Guice Singletons are weird for me First I thought that IService ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); will work as singleton, but it returns ser=Service2@1975b59 ser=Service2@1f934ad its ok, it doesnt have to be easy. Injector injector = Guice.createInjector(); IService ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); works as singleton ser=Service2@1975b59 ser=Service2@1975b59 So i need to have static field with Injector(Singleton for Singletons) how do i pass to it Module for testing?

  • C#, Generic Lists and Inheritance

    - by Andy
    I have a class called Foo that defines a list of objects of type A: class Foo { List<A> Items = new List<A>(); } I have a class called Bar that can save and load lists of objects of type B: class Bar { void Save(List<B> ComplexItems); List<B> Load(); } B is a child of A. Foo, Bar, A and B are in a library and the user can create children of any of the classes. What I would like to do is something like the following: Foo MyFoo = new Foo(); Bar MyBar = new Bar(); MyFoo.Items = MyBar.Load(); MyBar.Save(MyFoo.Items); Obviously this won't work. Is there a clever way to do this that avoids creating intermediate lists? thanks, Andy
