  • What is the "box model?"

    - by Chris
    During a recent interview for a front-end developer position I was asked what the box model was. I thought the interviewer was referring to testing (i.e. white box testing, black box testing). I was wrong. What is the box model, in reference to front-end development?

  • Memory leak with preg_replace

    - by Silvio Donnini
    I'm using the preg_replace function to replace accents in a string, I'm working with UTF-8. I have incurred in what seems to be a memory leak, but I can't isolate the root cause, my code is rather simple: preg_replace( array_keys($aToNoAccents), array_values($aToNoAccents), $sText ); where $aToNoAccents is an associative array with entries like '~[A]~u' => 'A', '~[C]~u' => 'C',. My script prints this error for the above line: Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 3039 bytes) Obviously it's not a matter of increasing the allowed memory for PHP, (a 1Gb footprint is way off the scale of my application). Also, that line is executed thousands of times without problems but, just for some cases which are difficult to reproduce, it yields the error. Is anyone aware of memory problems with preg_replace and UTF-8 strings? Am I to use special care in passing actual parameters to such function? I'm using PHP 5.2.6-3 with Suhosin-Patch thanks Silvio

  • Double pointer as Objective-C block parameter

    - by George WS
    Is it possible (and if so, safe) to create/use a block which takes a double pointer as an argument? For instance: - (void)methodWithBlock:(void (^)(NSError **error))block; Additional context, research, and questions: I'm using ARC. When I declare the method above and attempt to call it, XCode autocompletes my method invocation as follows: [self methodWithBlock:^(NSError *__autoreleasing *error) {}]; What does __autoreleasing mean here and why is it being added? I presume it has something to do with ARC. If this is possible and safe, can the pointer still be dereferenced in the block as it would be anywhere else? In general, what are the important differences between doing what I'm describing, and simply passing a double pointer as a method parameter (e.g. - (void)methodWithDoublePointer:(NSError **)error;)? What special considerations, if any, should be taken into account (again assuming this is possible at all)?

  • Is it possible to utilize internal methods on controllers to reduce duplication?

    - by Maslow
    in a partial view I have the following: <%Html.RenderAction(MVC.User.GetComments(Model.UserGroupName)); %> can I render a Controller's PartialViewResult in a View without going through routing so I can pass arguments directly from the model so that the arguments I'm passing to the controller never get sent to the user or seen by the user? Currently the method I'm showing at the top throws an exception because no overload is public. I've got it marked as internal so that a user can not access it, only the rendering engine was my intent.

  • How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

    - by brock
    Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

My app relies on a user defined server url and I would like to be able to set a URL scheme to launch my app using the users custom URL from lets say an email link.

  • Model Binding an IList of selected items only

    - by jeef3
    I have an action method setup: public ActionResult Delete(IList<Product> products) And a table of products in my view. I have got Model Binding working so that on submit I can populate the products list. But I would like to populate it with only the products that are selected via a checkbox. I think I could do it by changing the action method to this: public ActionResult Delete(IList<Product> products, IList<int> toDelete) And passing the list of check boxes to the toDelete but I would really like to avoid changing the method signature if possible. Is there a way to pass only the selected items? Or am I going to have to write a custom ModelBinder?

  • Accessing Sabre Web Services using PHP

    - by Peter
    I have been approached to create a website using Sabre Web Services to power the reservations system. All documentation I have seen refers to .NET or Java solutions, I was in doubt whether PHP can be used as access is performed using SOAP. I have found no further information about this, I assume the answer is yes, but wonder why there is not a single reference to this being possible - all solutions seem to be .NET Any suggestions? Thanks!

  • ebook reader for programming books?

    - by Martin
    Are the current ebook readers good enough for reading programming books (containing diagrams, source-code, screenshots, and so on)? How good are the search functions or the possibilities to set bookmarks, to use a book as a reference? I'd like to hear opinions of ebook reader owners to help me decide whether or not I should buy an ebook reader. (I know this question already exists, but it's over one year old and new ebook readers are now available)

  • compiler warning at C++ template base class

    - by eike
    I get a compiler warning, that I don't understand in that context, when I compile the "Child.cpp" from the following code. (Don't wonder: I stripped off my class declarations to the bare minuum, so the content will not make much sense, but you will see the problem quicker). I get the warning with VS2003 and VS2008 on the highest warning level. The code AbstractClass.h : #include <iostream> template<typename T> class AbstractClass { public: virtual void Cancel(); // { std::cout << "Abstract Cancel" << std::endl; }; virtual void Process() = 0; }; //outside definition. if I comment out this and take the inline //definition like above (currently commented out), I don't get //a compiler warning template<typename T> void AbstractClass<T>::Cancel() { std::cout << "Abstract Cancel" << std::endl; } Child.h : #include "AbstractClass.h" class Child : public AbstractClass<int> { public: virtual void Process(); }; Child.cpp : #include "Child.h" #include <iostream> void Child::Process() { std::cout << "Process" << std::endl; } The warning The class "Child" is derived from "AbstractClass". In "AbstractClass" there's the public method "AbstractClass::Cancel()". If I define the method outside of the class body (like in the code you see), I get the compiler warning... AbstractClass.h(7) : warning C4505: 'AbstractClass::Cancel' : unreferenced local function has been removed with [T=int] ...when I compile "Child.cpp". I do not understand this, because this is a public function and the compiler can't know if I later reference this method or not. And, in the end, I reference this method, because I call it in main.cpp and despite this compiler warning, this method works if I compile and link all files and execute the program: //main.cpp #include <iostream> #include "Child.h" int main() { Child child; child.Cancel(); //works, despite the warning } If I do define the Cancel() function as inline (you see it as out commented code in AbstractClass.h), then I don't get the compiler warning. Of course my program works, but I want to understand this warning or is this just a compiler mistake? Furthermore, if do not implement AbsctractClass as a template class (just for a test purpose in this case) I also don't get the compiler warning...?

  • Visual Studio 2010 - References Dialog Filter

    - by Sphynx
    Visual Studio 2010 adds a new feature to improve loading speed of references in "Add .NET Reference" tab. For example, when the target framework of project is 3.5, it displays only 3.5 assemblies in the list, and says "Filtered to: .NET Framework 3.5". This feature is quite annoying, as it makes impossible to find an older assembly, unless you change a target framework in compilation options. Is there any option to disable that filtering?

  • Is POSTing a Dictionary to an .NET MVC action possible?

    - by Brenton Alker
    I have a form which contains a series of fields like: <input type="text" name="User[123]" value="Alice" /> <input type="text" name="User[456]" value="Bob" /> ... Where the index of the User array (123 and 456) are ID's associated with the value. I'm trying to update these values in the controller. My thinking is that a Dictionary that maps ID to name would work, but creating the action like: public void Save(Dictionary<string, string> user) { // ... } results in the user parameter being null. So, is passing a Dictionary possible? or, is there another method to achieve this?

  • Loading remote assembly from the webservice with reflection

    - by Myat Htut
    I am using Assembly.LoadFrom within a web service to load assemblies from a web site. but the problem is it is in the virutal directory and the server.mappath parses the url like \share\mydll.dll and loadform method failed. Is there anyway to reference dll from the remote location? I've tried passing the url (http:\localhost\downloadable\mydll.dll) and again it got "Could not load file or assembly 'http:\localhost\downloadable\mydll.dll' or one of its dependencies. HTTP download of assemblies has been disabled for this appdomain. (Exception from HRESULT: 0x80131048)"

  • CompilationMode=Never & SessionState

    - by Nariman
    It seems that CompilationMode=Never doesn't permit Sessions to be properly wired. It first complains that the EnbaleSessionState directive is not allowed on this page. Explicitly assigning the System.Web.SessionState.IRequiresSessionState to the Page [1] avoids the null reference exceptions (around .Session access) but still doesn't persist or wire-up sessions correctly. Has anyone successfully used ASP.NET Sessions with CompilationMode=Never? Conceptually, why should these be disjoint??

  • How to set timeout with python-mechanize?

    - by Michal Cihar
    I'm using python-mechanize to scrape some web sites, which sometime simply don't respond to requests and these requests stay open too long, so I need to limit timeout for these requests. While using urlopen method, the timeout can be set using timeout parameter, but I have not found easy way for doing it with high level API such as submit or click methods. Ideally the timeout would be set just once for whole browser class and all calls would honor that. It would be probably possible to customize this by passing custom request_class to every click and submit call, but this would just pollute the code, so I'm looking for nicer solution for setting timeout for mechanize's browser class (and no, I don't want to change default socket timeout using socket.setdefaulttimeout).

  • Easy to get a test file into JUnit

    - by Benju
    Can somebody suggest an easy way to get a reference to a file as a String/InputStream/File/etc type object in a junit test class? Obviously I could paste the file (xml in this case) in as a giant String or read it in as a file but is there a shortcut specific to Junit like this? public class MyTestClass{ @Resource(path="something.xml") File myTestFile; @Test public void toSomeTest(){ ... } }

Something like: //*[@id="cell_"*] How do I do this? Also, if anybody can point me to a good XPath reference it would be very helpful. Thanks!
