  • Use javascript to extend a DOM Range to cover partially selected nodes

    - by ko-dos
    I'm working on a rich text editor like web application, basically a XML editor written in javascript. My javascript code needs to wrap a selection of nodes from the contentEditable div container. I'm using the methods described at MDC. But since I need to synchronize the div containers content to my XML DOM I would like to avoid partial selections as described in w3c ranges: <BODY><H1>Title</H1><P>Blah xyz.</P></BODY ............^----------------^............ This selection starts inside H1 and ends inside P, I'd like it to include H1,P completely. Is there an easy way to extend the selection to cover partially selected children completely? (The code doesn't need to work with opera/IE)

  • "And" condition in C#/LINQ Query

    - by user1213055
    partial void PrintDocLetter1_CanExecute(ref bool result) { if (this.PatientsMasterItem.DoctorsMasterItem != null) { var Doctor = PatientsMasterItem.DoctorsMasterItem; var PatientList = Doctor.PatientsMasterItem; var Letters = PatientsMasterItem.LettersSentItem; if ((PatientList.Count() > 1) && (Letters.Any(i => i.LetterType == "DoctorLetter1"))) { result = false; } else { result = true; } } } I think something is wrong with my second condition. I'm trying to find two things. 1) Doctors with more than 1 patient. 2) Among those patients whether a lettertype called "DoctorLetter1" has been sent or not. The above code is working good for that particular record but not working other patients with same doctors where patient1 has already been sent with DoctorLetter1.

  • Creating and Compiling a C++ project on Windows

    - by sc_ray
    I need to work on C++ project on my windows machine. My project will consist of various classes(.h and .cpp) as well as the startup file to start the application.

What I need here is ideas to set up the C++ project compiler/IDE/Makefile etc..etc. as well as some standard tools besides Visual C++ to compile/build/link projects such as these on a Windows OS. Thanks

  • CSS: a:link vs just a (without the :link part)

    - by Rob
    So we're required to use the following order for CSS anchor pseudo-classes a:link { color: red } a:visited { color: blue } a:hover { color: yellow } a:active { color: lime } But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over: a { color:red; } /* notice no :link part */ a:visited { color: blue; } etc.,etc.

  • Is it possible for an abstract class to force it's children to have a constructor in PHP?

    - by Logan Serman
    I would like to do something like this: abstract class Foo { public function __construct() { echo 'This is the parent constructor'; } abstract function __construct(); } class Bar extends Foo { // constructor is required as this class extends Foo public function __construct() { //call parent::__construct() if necessary echo 'This is the child constructor'; } } But I get a fatal error when doing this: Fatal error: Cannot redeclare Foo::__construct() in Foo.php on line 8 Is there another way to ensure child classes have a constructor?

  • Determining the calling package

    - by Nachikethas
    I got a package called 1.pm in that the constructor is calling a subroutine which is in the same package. Now if some other classes say 2.pm is calling the constructor defined in 1.pm how can i determine if the subroutine is called from 2.pm ?

  • Initiatives to namespace PHP core and libraries

    - by James Maroney
    With the introduction of Object-Oriented and Namespacing capabilities in PHP, I am loving the new found cleanliness of PHP code that can be produced. The annoying thing though is that the core of PHP is still cluttered, unorganized mess of functions. Are there any initiatives to organize the PHP core and "common" libraries into namespaces and classes?

    - by steve
    Greetings, I'm confused as to the best approach to make when consuming REST based web services with .Net. At the moment I'm using the System.net.webclient class. Should I be using Webresponse, webrequest classes in System.Net ? If I were to use another approach (Other than webclient) what disadvantages / advantages would I gain ? Thanks,

  • Is it the best practice to extract an interface for every class?

    - by the_drow
    I have seen code where every class has an interface that it implements. Sometimes there is no common interface for them all. They are just there and they are used instead of concreate objects. They do not offer a generic interface for two classes and are specific to the domain of the problem that the class solves. Is there any reason to do that?

  • Java interface 'interview'-style problem

    - by Codenotguru
    Problem/Task: Write an interface with one method and two classes that implement this interface. Now write a main method with an array that holds an instance of each class. Using a for-each loop, invoke the method upon each item. Is this an interview question? (I'm not sure if the author meant to post this as a question or was looking for an answer to the above.)

  • URL getRequestParameterMap not working

    - by DD
    I'm using IceFaces 1.8.2 and trying to get a parameter from the URL using: ((HttpServletRequest) FacesContext.getCurrentInstance() .getExternalContext().getRequest()).getParameter(name); This works fine on the inital request. However, when I do a partialSubmit on a component, it stops working. I'm assuming that its to do with how requests are processed when partial submits are done. Is there a workaround? At the moment, I'm having to ((HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext() .getRequest()).getQueryString(); and manually pass the query string. Thanks.

  • Static member class - declare class private and class member package-private?

    - by Helper Method
    Consider you have the following class public class OuterClass { ... private static class InnerClass { int foo; int bar; } } I think I've read somewhere (but not the official Java Tutorial) that if I would declare the static member classes attributes private, the compiler had to generate some sort of accessor methods so that the outer class can actually access the static member class's (which is effectively a package-private top level class) attributes. Any ideas on that?

  • Alternatives to persisting objects than using __destruct() in PHP

    - by Michael
    I usually use a classes destructor method __destruct() to persist objects to session or what have you. It is just very convinient, but I'm curious to if there are any other methods that are equally appealing. Do you know of such? The curiousity arose as I was to merge/utilize two frameworks that both made use of __destruct() for persistance resulting in a race-problem.
