• Setting refresh-policies in Ehcache

  - by Alex Ciminian

  Is there any to specify a data refresh policy in Ehcache? I am currently migrating an application from OSCache to Ehcache and I can't seem to find any way to specify when an element needs refreshing, besides setting timeToIdle and timeToLive. What I want is: on accessing an element from the cache, check with it's associated resource to see if it was updated later than the lastUpdateTime of the cache element. If yes, refresh the cache; else serve the content from the cache. In OSCache this was done by catching NeedsRefreshExceptions and setting custom refresh policies for the elements. I've been digging around in the docs for a while now, but I wasn't able to find any methods or examples of how I could accomplish this in Ehcache. Any help would be appreciated :). Alex

• How to get contents of Amazon shopping cart?

  - by Andrew Whitehouse

  I've been investigating whether it's possible to get a list of the saved items in my Amazon shopping basket programmatically ... Their Product Advertising API has methods for getting wishlists: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/index.html?FindingItemsonLists.html and working with remote shopping carts: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/index.html?CHAP_WorkingWithRemoteShoppingCarts.html but the shopping cart of items stored while on the Amazon web site is treated as a local shopping cart, and therefore is not accessible through the Product Advertising API. According to the last link: The opposite of a remote shopping cart is a local shopping cart, which is the shopping cart customers use while shopping on www.amazon.com. It is considered local because Amazon hosts the shopping web pages as well as the shopping cart. Product Advertising API operations work solely with remote shopping carts. Has anyone found a way of getting the contents of the "local" cart, apart from scraping the HTML? Thanks.

• Best placement for javascript in Asp.net MVC app that heavily uses partial views

  - by KallDrexx

  What is the best place for javascript that is specific to a partial view? For example, if I have a partial view (loaded via ajax call) with some divs and I want to turn those divs into an accordian, would it be better put the $("#section").accordion() in script tags inside of the partial view, or in a .js file in the function that retrieves that partial view and inserts it into the DOM? Obviously, common methods I will be keeping in a .js file, however I am more talking about javascript very specific to the partial view itself. Most things I find on the net seem to say to put all javascript into a separate .js but nothing addresses the idea of partial views.

• How to get global variable in JQuery functions

  - by Tahir Akram

  I want to access my global javascript variable in JQuery methods. But I am unable to get it when I go to attach a click even to a div. As following. How can I do that? I mean do I need to rely on hidden fields for some state management? var divCount = 3; $(function() { //divCount is accessible here $("#sortable").sortable({ revert: true }); $("#new").click(function(){ if (divCount<7){ //divCount is not accessible here. why? and how? var thisCount = ++divCount; $("#draggable_"+thisCount).addClass("draggable"); } }); });

• iPhone Dev: Animating PNG Sequences

  - by Franky

  What is the best or recommended technique for animating PNG Sequences. Heres what I've learned: Do it Manually Using MutableArrays containing Strings, you can animate a UIImageView with a timer which increments an index number UIImage - animation methods This works, the only problem is to find if an image has completed its animation, you have to check the isAnimating BOOL, and to do that you need a timer. What is the best and recommended? Looking to do Oldschool game sprite animations, ie: Idle Animation Attack Animation Walk Animation ect... Let me know if any one has something. @lessfame

• Instrumentation class in the Android API.

  - by Riyas

  Hi All, I have question on the Android API. Android API provides a class called "Instrumentation" class. What is the use of this class? Is the Instrumentation class be used only together with Junit for unit testing. Can Junit framework can be used to test the methods of the Android API without using the Instrumentation class. Since Junit package has been included in the Android package, I hope we dont need to use install separately for unit testing. I would appreciate if you could provide me the information as i can't find these clear information anywhere on the Web. If we use Junit test framework to test the Android API, can we have test results in the UI format rather than test format.? Thanks a lot. Apprecite your time. Regards, Riyas

• C++/CLI .ToString() returning error

  - by George Johnston

  I am a beginner to C++/CLI as I come from a C# background. I am currently writing a wrapper for some native C++ code. I have the following methods: void AddToBlockList(System::String^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address); _packetFilter->AddToBlockList(cAddress); } void AddToBlockList(IPAddress^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address.ToString()); _packetFilter->AddToBlockList(cAddress); } ...The first method works fine and converts my string into the character array. However, the second function with the IPAddress object as the signiture gives me the following error: error C2228: left of '.ToString' must have class/struct/union ...When I type ? address.ToString() ...in the command window, the IP Address prints. Not sure where I'm going wrong. Any ideas?

• iPhone - Bug using CADisplayLink and UIControls - bad to mix openGL and UIControls?

  - by Adam

  Having had problems using other methods, I've decided to stick with CADisplayLink to run my game loop. The animation is smooth now, but sometimes there's a problem where the buttons and other UI elements can't be used, can't be accessed by touch or changed programmatically. This includes UIButtons and UILabels. Has anyone encountered this before? Is it not a good idea in general to use interface builder and uicontrols on top of an OpenGL view? I've heard they don't play well together but haven't heard the reasons. Thanks!

• Generate links for routes with non-parameter url segments on ASP.NET MVC 2

  - by spapaseit

  I have a route defined with several hardcoded (non-parameter) segments: routes.MapRoute(null, "suggestion/list/by/{tag}", new { controller = "Suggestion", action = "List", tag = UrlParameter.Optional }); Suppose I'm in the Index view of SuggestionController, which has a Suggestion object for Model, how can I create a link that matches that route? I'd rather use one of the provided helpers and keep the route name as null in order to avoid hard-coding to much on my views, but I can't figure out how to user these non-parameter segments in Html.ActionLink or RouteLink methods. I've even tried to render the link using plain ol' html <a href="/suggestion/list/by/<%=Model.Tag %>"><%=Model.Tag %></a> but this somehow didn't match the route either. There's probably a very simple solution and I might be over-complicating things in mi mind, but I'm at a loss. Any ideas? Thanks in advance.

• OpenLayers .containsPoint after pan

  - by Adrian

  I've seem to have hit a bug or i have overlooked something. I written some code that enumerates through all the vector features on a OpenLayers Vector layer - to check if the mouse is inside a vector feature - if so then it displays some info based on the feature. I had to write my own methods to do this because the existing OpenLayers Controls( select etc) stop after finding a feature under the mouse, and i the possibility of several features being stacked on top of one another. My problem is that the .containsPoint method seems to be using coords from before a 'pan'. After zooming in or out the geometry seems to be in the right place and .containsPoint is works correctly when I wave the mouse over the map. Do I need to do something after the map has been panned to update something( feature's geometry)

• EJB 3 Session Bean Design for Simple CRUD

  - by sdoca

  I am writing an application that's sole purpose in life is to do CRUD operations for maintaining records in database. There are relationships between some of the tables/entities. Most examples I've seen for creating session beans deals with complex business logic/operations that interact with many entities which I don't have. Since my application is so very basic, what would be the best design for the session bean(s)? I was thinking of having one session bean per entity which had CRUD the methods defined. Then I thought of combining all of those session beans into a single session bean. And then I found this blog entry which is intriguing, but I must admit I don't understand all of it (what is a ServiceFacade?). I'm leaning towards session bean/entity class, but would like to hear more experienced opinions. Thanks.

• How can I change the name of a dynamic assembly after it has been created?

  - by Samuel Jack

  Is there any way to change the name of a dynamic assembly after it has been created? I'm using a framework that uses dynamic methods, and it is creating a dynamic assembly with the same name as my main assembly (which causes problems with WPF when it tries to load resources). So I need to find a workaround, and I thought of trying to change the name of the dynamic assembly. I've tried using GetName() and then setting the Name property, but it appears that GetName returns a clone of the name because my change doesn't stick. What else can I try?

• Stop applet execution on load, pause/resume using javascript?

  - by Zane

  I'm making something of a java applet gallery for my website (processing applets, if you're interested) and I'd like to keep the applets from running when the sit first loads. Then, when the appropriate button is clicked, a piece of javascript would tell the applet to continue execution until another button is pressed to stop it. I know that I can use appletName.start() and appletName.stop(), but it doesn't seem to work on load, at least not well. I'm using element.getElementsById( "applet" ) to get the applets to use the start and stop methods on. It slows Firefox to a crawl for some reason.

• Adding Listeners at runtime? - Java MVC

  - by Halo

  My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

• Are there any free .NET OCR libraries that will perform OCR on an application window directly?

  - by Kelsey

  I am looking for a free .NET OCR library that will be able to do OCR on a given application window or even a image in memory (I can take a snapshot of the application window myself). I have looked at tessnet2 and MODI but both require an image located on disk. I need to use OCR because the application I am trying to write a script for does some wacky stuff that cannot be read using windows API and I need to scrape data from the screen. I have tested both of tessnet2 and MODI and they both can read the text mostly but because this has to run in an enviroment that will not be able to write to disk, I need it to be able to read directly from the applciation window or some type of memory stream. I am thinking OCR is my only soution but there could be other methods that I am not thinking of. Suggestions?

• Choosing routing.yml based on user culture?

  - by Erland Wiencke

  In my Symfony application I would like to choose the routing.yml based on the current user's culture; 'en' => routing.en.yml 'no' => routing.no.yml and so forth. Any suggestion to how this can be done? Edit: I am not trying to do i18n this way - I use Symfony's built-in methods for that. I simply want "static" urls to reflect the user's language: /en/projects/internal/project-name /no/prosjekter/interne/prosjektnavn /fr/baguette/champs-elysee/foux-de-fafa Where "projects" is a module, the category "internal" and "project-name" are stored in the database.

• using Dependency Parser in Stanford coreNLP

  - by Eddie Dovzhik

  I am using the Stanford coreNLP ( http://nlp.stanford.edu/software/corenlp.shtml ) in order to parse sentences and extract dependencies between the words. I have managed to create the dependencies graph like in the example in the supplied link, but I don't know how to work with it. I can print the entire graph using the toString() method, but the problem I have is that the methods that search for certain words in the graph, such as getChildList, require an IndexedWord object as a parameter. Now, it is clear why they do because the nodes of the graph are of IndexedWord type, but it's not clear to me how I create such an object in order to search for a specific node. For example: I want to find the children of the node that represents the word "problem" in my sentence. How I create an IndexWord object that represents the word "problem" so I can search for it in the graph?

• Passing a non-iterable to list.extend ()

  - by JS

  Hello, I am creating a public method to allow callers to write values to a device, call it write_vals() for example. Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example: write_to_device([1,2,3]) or write_to_device(1) My function would like to work with a flat list, so I tried to be clever and code something like this: input_list = [] input_list.extend( input_val ) This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer: TypeError: 'int' object is not iterable Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten. Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods. Suggestions (coding-related only, please) would be greatly appreciated.

• Invoke a subclass method of an anonymous class

  - by arjacsoh

  I am trying right now to dig into anonymous classes and one question was just arised I 'd prefer not to refer to much details and to pose my question straightforward: How can I invoke the method sizzle() in the following anonymous class: public class Popcorn { public void pop() { System.out.println("popcorn"); } } class Food { Popcorn p = new Popcorn() { public void sizzle() { System.out.println("anonymous sizzling popcorn"); } public void pop() { System.out.println("anonymous popcorn"); } }; public void popIt() { p.pop(); // OK, Popcorn has a pop() method p.sizzle(); // Not Legal! Popcorn does not have sizzle() } } It is known and definite in polymorphism rules that a refernce of a superclass cannot invoke methods of subclass without downcasting (even if it refers to an object of the given subclass). However in the above case what is the "key" to invoke the sizzle() method?

• IDL in ATL/COM: Can I publish a const of a complex type?

  - by Ptah- Opener of the Mouth

  I know how to publish a const of a simple type in IDL, for example: const long blah = 37 But I want to publish consts of complex types, with methods, or at least readable struct-like member fields. For example, perhaps a type called CarType, which has accessor fields like "get_Make", "get_Model", "get_Year", "get_BasePrice", et cetera. Then I would like to publish const instances, such as FORD_PINTO_1973. (Please don't read too much into the example, to tell me that this particular example would lend itself better to just regular classes without const instances or something like that). I have no idea how I would define, in IDL, the fact that FORD_PINTO_1973 has a Year field of 1973. Thanks in advance for any help.

• Why C# calls different overloaded method for different values of same type?

  - by Fabio Veronez

  Hello all, I have one doubt concerning c# method overloading call resolution. Let's suppose I have the following C# code: enum MyEnum { Value1, Value2 } public void test() { method(0); // this calls method(MyEnum) method(1); // this calls method(object) } public void method(object o) { } public void method(MyEnum e) { } Note that I know how to make it work but I would like to know why for one value of int (0) it calls one method and for another (1) it calls another. It sounds awkward since both values have the same type (int) but they are "linked" for different methods. Ps.: This is my first question here, i'm sorry if I made something wrong. =P

• Are there any differences between MSSQL and MySQL when it comes to preventing SQL injection?

  - by Derek Adair

  I am used to developing in PHP/MySQL and have no experience developing with MSSQL. I've skimmed over the PHP MSSQL documentation and it looks similar to MySQLi in some of the methods I read about. For example, with MySQL I utilize the function mysql_real_excape_string(). Is there a similar function with PHP/MSSQL? What steps do I need to take in order to protect against SQL injection with MSSQL? What are the differences between MSSQL and MySQL pertaining to SQL injection prevention?

• A way to avoid deriving from the provider classes in mvc authentication

  - by Shymep

  Looking for the best practice for authentication in MVC I unfortunately didn't find the clear answer to my question. Thinking of the problem I tried to imagine some priciples that could be useful in my design. Well, I would like to use a base AccountController class I want to place all the tables such as "Users", Roles, Rights etc into my own database. But I wouldn't like to implement the standard aspnetdb design (which can be easy got by using aspnet_regsql) So the main question is can I do this without deriving abstract classes like MembershipProvider, RoleProvider etc? What I would prefer not to do is implement all the abstract methods from these classes. The second question is still about the best practice for authentication e.g. for the small projects, for the large ones?
