  • JAXB - representing an element as a boolean member?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • MVVM (ICommand) in Silverlight

    - by Andrey Khataev
    Hello! Please, don't judge strictly if this question was discussed previously or indirectly answered in huge nearby prism and mvvm blogs. In WPF implementation of RelayCommand or DelegateCommand classes there is a such eventhandler /// <summary> /// Occurs whenever the state of the application changes such that the result of a call to <see cref="CanExecute"/> may return a different value. /// </summary> public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } but in SL subset of namespaces there are no CommandManager class. And this is where I'm stuck. I haven't yet found an workaround for this in MVVM adoptation for SL (PRISM is so complex for me yet). Different simple HelloWorldMVVM apps don't deal with at all. Thanks in advance and sorry for my English -)

  • jQuery exclude elements with certain class in selector

    - by Alex Crooks
    I want to setup a click event trigger in jQuery for certain anchor tags. I want to open certain links in a new tab while ignoring ones with a certain class (before you ask I cannot put classes on the links I am trying to catch as they come from a CMS). I want to exclude links with class "button" OR "generic_link" I have tried $(".content_box a[class!=button]").click(function (e) { e.preventDefault(); window.open($(this).attr('href')); }); But that doesn't seem to work, also how do I do an OR statement to include "generic_link" in the exclusion? Many thanks

  • jQuery selector help - Can I generate a selector from clicking on an element?

    - by Kettenbach
    Hi All, I have jQuery, FireFox, Firebug, IE, and IE developer toolbar. When I am examing a page with either FireBug or IE Dev toolbar, I am able to click on an element and it shows me in the dom where the element is etc... Is there anyway to transform that selection into a valid jQuery selector? I know I can use ID, classes, and element relative to other elements etc... but what about when I am looking at some random table cell that doesn't have a class or id etc.. Can I generate a selector on the fly like that? I thought for sure there was. Any thoughts or ideas are always appreciated Thanks, ~ck in San Diego

  • Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

    - by Brann
    I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

  • Ordering the calling of asynchronous methods in c#

    - by Peter Kelly
    Hi, Say I have 4 classes ControllerClass MethodClass1 MethodClass2 MethodClass3 and each MethodClass has an asynchronous method DoStuff() and each has a CompletedEvent. The ControllerClass is responsible for invoking the 3 asynchronous methods on the 3 MethodClasses in a particular order. So ControllerClass invokes MethodClass1.DoStuff() and subscribes to MethodClass1.CompletedEvent. When that event is fired, ControllerClass invokes MethodClass2.DoStuff() and subscribes to MethodClass2.CompletedEvent. When that event is fired, the ControllerClass invokes MethodClass3.DoStuff() Is there a best practice for a situation like this? Is this bad design? I believe it is because I am finding it hard to unit test (a sure sign) It is not easy to change the order I have an uneasy, code-smell feeling about it What are the alternatives in a situation like this?

  • What is the difference between File and FileInfo in C# ?

    - by Lilitu88
    I've been reading that the static methods of the File Class are better used to perform small and few tasks on a file like checking to see if it exists and that we should use an instance of the FileInfo Class if we are going to perform many operations on a specific file. I understand this and can simply use it that way blindly but I would like to know why is there a difference ? What is it about the way they work that make them suitable for different situations ? What is the point of having this 2 different classes that seem do the same in different ways ? It would be helpful if someone could answer at least one of this questions.

  • handle when callback to a dealloced delegate?

    - by athanhcong
    Hi all, I implemented the delegate-callback pattern between two classes without retaining the delegate. But in some cases, the delegate is dealloced. (My case is that I have a ViewController is the delegate object, and when the user press back button to pop that ViewController out of the NavigationController stack) Then the callback method get BAD_EXE: if (self.delegate != nil && [self.delegate respondsToSelector:selector]) { [self.delegate performSelector:selector withObject:self withObject:returnObject]; } I know the delegate-callback pattern is implemented in a lot of application. What is your solution for this?

  • How to do relative imports in Python?

    - by Joril
    Imagine this directory structure: app/ __init__.py sub1/ __init__.py mod1.py sub2/ __init__.py mod2.py I'm coding mod1, and I need to import something from mod2. How should I do it? I tried from ..sub2 import mod2 but I'm getting an "Attempted relative import in non-package". I googled around but found only "sys.path manipulation" hacks. Isn't there a clean way? Edit: all my __init__.py's are currently empty Edit2: I'm trying to do this because sub2 contains classes that are shared across sub packages (sub1, subX, etc.). Edit3: The behaviour I'm looking for is the same as described in PEP 366 (thanks John B)

  • Class as an Event Observer

    - by emi
    I want to do something like this... var Color = Class.create({ initialize: function() { this._color = "white"; this.observe("evt: colorChanged", this.colorChanged.bind(this)); }, changeColor: function(color) { this._color = color; this.fire("evt: colorChanged"); }, colorChanged: function(event) { alert("You change my color!"); } }); var a = new Color().changeColor("blue"); Why the colorChange custom event will never be dispatched and I need to use, instead of this, a DOM element like document.observe? In my code I'd like to know which class dispatches the event using event.target and I can't if I must use document or some other DOM element. :( I've been working in Actionscript 3 and that's the methodology I learned to work with custom events in classes. What about Javascript?

  • Using NSURLRequest+NSURLConnection seems overkill for a webcall with no data return

    - by Spectravideo328
    All, This might seems very straightforward but I have already gone through the URL loading system program guide and the various NSURL.... classes and not found my answer. I am just trying to do a simple call from the app to a website to reserve a party spot: NSString *path=[NSString stringWithFormat:@"http://www.myparty123.com/ireservedURL.asp?Nickname=%@&Seat=%i&Email=%@&Currentparty=%i",john,5432,[email protected],6598]; NSURL* reservationURL =[NSURL URLWithString:path]; NSData *call= [NSData dataWithContentsOfURL:reservationURL]; This seemed to be the simple way but I get this warning that I am not using the "call" variable. And it seems overkill to do a call using NSData where there is no data return. Yet, creating an NSURLRequest and initiating an NSURLConnection and then implementing delegates with that request seems to be overkill as well. What am I missing. Thanks KMB

  • boost::dynamic_pointer_cast with const pointer not working ?

    - by ereOn
    Hi, Let's say I have two classes, A and B, where B is a child class of A. I also have the following function: void foo(boost::shared_ptr<const A> a) { boost::shared_ptr<const B> b = boost::dynamic_pointer_cast<const B>(a); // Error ! } Compilation with gcc gives me the following errors: C:\Boost\include/boost/smart_ptr/shared_ptr.hpp: In constructor 'boost::shared_ptr< <template-parameter-1-1> >::shared_ptr(const boost::shared_ptr<Y>&, boost::detail::dynamic_cast_tag) [with Y = const A, T = const B]': C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:522: instantiated from 'boost::shared_ptr<X> boost::dynamic_pointer_cast(const boost::shared_ptr<U>&) [with T = const B, U = const A]' src\a.cpp:10: instantiated from here C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:259: error: cannot dynamic_cast 'r->boost::shared_ptr<const A>::px' (of type 'const class A* const') to type 'const class B*' (source type is not polymorphic) What could possibly be wrong ?

  • Safest way to change variable names in a project

    - by kamziro
    So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

  • What are good educational resources for setting up .Net Webservice on a DMZ connecting to SQL Server

    - by Brian
    We are going to begin implementing a web service that will be hosted on a DMZ server. This web server will post data to a SQL server and we're trying to determine the best methodology to handle this. Things that concern us are web service authentication, SOAP, and whether or not to store the database on the DMZ or the local network. This same scenario will apply to ASP.Net apps. Trust me, I've already searched the web, but as usual, the online resources I've found either talk about just authentication, or just about SOAP, or etc, but does not show or suggest how the entire system can work together. Can you give me a list of resources such as links that I've missed, books, classes, or etc that would help? Thank You.

  • Is removing unused functionality a bad thing?

    - by Andrew Grimm
    Is it possible for YAGNI to apply in the past tense? You created some functionality, it was used a little bit a while ago, but you aren't using it any more, and you don't want to maintain it, so you'd rather delete it. Is getting rid of unused or rarely-used functionality neccessarily a bad thing? Background: I use source control, so if I need the functionality again, I can get it. I'm the only user of my software (I'm a bioinformatician analyzing a data set). One scenario where I came across this was that I was using inheritance, with a parent class, and two child classes. One was handling files generated by 454 sequencing (next-generation sequencing), and the other was handling files generated by Sanger sequencing (previous-generation sequencing). I was actively maintaining the latter, but not the former. Maybe my mistake was using inheritance rather than composition, but that's a slightly different story.

  • makefile compilation problem

    - by mistique
    He I have a problem with a makefile. I have three classes. They do pretty simple stuff. One does an addition on a subtraction, and the last one will instantiate the two and simply print the resulted addition and subtraction. Now when I create my makefile, I compile my Plus.java and my Minus.java but don't know how to compile the main class because it depends on the previous two. I want to compile and run it from the makefile if it's possible. I get the above results when I try to run make: javac -g Plus.class Minus.class javac: invalid flag: Plus.class Usage: javac use -help for a list of possible options make: * [Operation.class] Error 2 I don't know how to procede, please forgive me if my question is to simple but I am new working with these stuff. I've searched many sites but with no answer.

  • Error in writting a class.

    - by Richard
    I am running through a tutorial online at http://www.sthurlow.com/python/lesson08/ and I believe I understand how classes work in python, at least to some degree but when I run this code: class Shape: def init(self,x,y): self.x = x self.y = y description = "This shape has not been described yet" author = "Nobody has claimed to make this shape yet" def area(self): return self.x * self.y def perimeter(self): return 2 * self.x + 2 * self.y def describe(self,text): self.description = text def authorName(self,text): self.author = text def scaleSize(self,scale): self.x = self.x * scale self.y = self.y * scale I get this error: Traceback (most recent call last): File "Y:/python/Shape.py", line 1, in -toplevel- class Shape: File "Y:/python/Shape.py", line 17, in Shape self.y = self.y * scale NameError: name 'self' is not defined Any Help would be great Thanks Richard

  • Parsing boolean from configuration section in web.config

    - by Bloopy
    I have a custom configuration section in my web.config. One of my classes is grabbing from this: <myConfigSection LabelVisible="" TitleVisible="true"/> I have things working for parsing if I have true or false, however if the attribute is blank I am getting errors. When the config section tries to map the class to the configuration section I get an error of "not a valid value for bool" on the 'LabelVisible' part. How can I parse "" as false in my myConfigSection class? I have tried this: [ConfigurationProperty("labelsVisible", DefaultValue = true, IsRequired = false)] public bool? LabelsVisible { get { return (bool?)this["labelsVisible"]; } But when I try and use what is returned like so: graph.Label.Visible = myConfigSection.LabelsVisible; I get an error of: 'Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Thanks for any suggestions!

  • jQuery Resizable() UI Problem

    - by OneNerd
    In general, resizable() works fine. Here is where I am getting into an issue. I have a div that contains some resizable items that work fine (resizable() applied to them at some point). user can save items for later view (the innerHTML of the div gets saved into a JavaScript array, then div gets cleared so they can do something else) When items get placed back onto div (from array) -- I do a $('#divname').append(arrayname[i]); -- items are no longer resizable (although visually they have the resizable classes/handle on them) Here is what I have tried so far (none of which have worked): After append() line, I re-initialize the resizable -- $('#items').resizable(); After append() line, remove then re-add resizable -- $('#items').resizable('destroy').resizable(); Any help is appreciated - thanks.

  • EntityManager and two DAO with PersistenceContextType.EXTENDED

    - by hsd
    Hi All, I have a problem with my entity manager in my application. I have two DAO clasess like this: @Repository public abstract class DaoA { protected ClassA persistentClass; @PersistenceContext(name="my.persistence", type=PersistenceContextType.EXTENDED) protected EntityManager entityManager; -------------- some typical action for DAO -------------- } Second DAO is for ClassB and looks similar to DaoA. The rest of things are done for me by the Spring framework. When I'm debugging the application I recognize that both DAO objects have different instances of EntityManager. In the result my two different DAOs are connected with different PersistenceContext. Question is if this is correct behaviour or not? I would like to have the same PersistenceContext for all my DAO classes. Please give me a hint if this is possible and if I understood the JPA correctly? Regards Hsd

  • Variable length Blob in hibernate?

    - by Seth
    I have a byte[] member in one of my persistable classes. Normally, I'd just annotate it with @Lob and @Column(name="foo", size=). In this particular case, however, the length of the byte[] can vary a lot (from ~10KB all the way up to ~100MB). If I annotate the column with a size of 128MB, I feel like I'll be wasting a lot of space for the small and mid-sized objects. Is there a variable length blob type I can use? Will hibernate take care of all of this for me behind the scenes without wasting space? What's the best way to go about this? Thanks!

  • deep injection - spring

    - by Bob
    What is the best way (or options) for accessing spring components at layers deep within the application that aren't managed by spring? For example, I have a low level utility POJO class into which I need to autowire/inject a spring component. I'll call it LowLevelHelper. There are multiple classes that use LowLevelHelper - most are layers away from anything that is hooked up with spring. One option would be to make all the layers in to spring components, but that seems like I'm hacking my design to force spring to help me. I have some complex things going on that won't be nearly as clean if I have to @Autowire all the pieces and don't new anything. Another option might be to manually inject the component in the low level class, but I'm not really sure if this is possible or the right solution.
