  • Would you make this method Static or not?

    - by Adam Drummond
    During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing. So I did quite a bit of research and obviously it's a specialized case but I would like to know what you would do in this situation and why? (Its basically a helper method I call from a few different methods, a very low traffic page. More for my knowledge and learning on Static.) private IEnumerable<Category> GetCategoryByID(int id, Context context) { var categoryQuery = from selectAllProc in context.SelectAll_sp() where selectAllProc.CategoryID == id select selectAllProc; return categoryQuery; }

  • jQuery fadeTo not working in IE8

    - by Lynda
    I have a div fading in using fadeTo. It works great in Firefox and IE9. It does not work in IE8. Here is my code: JS: var $j = jQuery.noConflict(); window.onload = function(){ $j('#fadein').fadeTo(6000, 1, function() { }); }; HTML <div class="img-center" id="fadein" style="opacity:0;"> <img src="src.jpg" alt="Text" class="feature-image" /> </div> How do I get this to work in IE8? I do not mind changing from fadeTo to fadeIn or some other method of fading in a div as long as it works in IE8.

  • Nested for_each with lambda not possible?

    - by Ela782
    The following code does not compile in VS2012, it gives error C2064: term does not evaluate to a function taking 1 arguments on the line of the second for_each (line 4 below). vector<string> v1; for_each(begin(v1), end(v1), [](string s1) { vector<string> v2; for_each(begin(v2), end(v2), [](string s2) { cout << "..."; }); }); I found some related stuff like http://connect.microsoft.com/VisualStudio/feedback/details/560907/capturing-variables-in-nested-lambdas which shows a bug (they are doing something different) but on the other hand that shows that what I print above should be possible. What's wrong with the above code?

  • <noscript> not working in Opera 11?

    - by cappuccino
    I am testing my noscript tags which display content when javascript is disabled, this works in Safari, Chrome, Firefox, Camino, IE6, IE7, IE8, IE9, basically everything but Opera (I'm running version 11, not sure if its isolated to that version). In Opera 11 nothing is displayed... is the noscript tag not supported? and what is the alternative? Nothing surprising: <noscript>Please enable JavaScript.</noscript> Located between the body tags. <html> <body> <script>alert('Hello World');</script> <noscript>Hello World!</noscript> </body> </html>

  • Flush() not working in drupal

    - by fawad
    I'm trying to post data from one node to another. The other node contains the for loop which iterates for long time and finally generates the table. I want to display the result after each iteration. I have tried to put "flush();" but it is not working. What should i do to display each iteration result on the node page? Note: If i do it with ob_flush() it works but it then starts printing data above the header which is not suitable. I want all the data inside the node.

  • creating BeanInfo objects in NetBeans 6.1 does not work for some objects

    - by Coder
    I have recently learned about BeanInfo classes in Java, and have successfully used them to add icons to my custom GUI components which extend swing components such as JTextField, however i have a more specialized GUI component which extends from another one of my GUI components, which then extends from JTextField. Ie. the class hierarchy is of the form "A - B - JTextField". I can create a bean info object that works for class B, but when i click on the bean info editor option in netbeans to create a bean info object for class A, nothing happens. Ie. there is no error pop-up and a bean info object is not created. There isn't much difference between class A and B. Both A and B have default no argument constructors and they are very similar to each other. The only thing i can really think of is that A uses generics and B does not. I would like to create a beaninfo object for class A so that i can add custom icons for that component. Any help would be appreciated. Thanks.

  • PHP CURL works fine from localhost not from server

    - by Joby Joseph
    I have 2 servers, srv1 and srv2. All client sites are stored in srv2 and all authentication details are stored in srv1. Each time a client site is loaded, the site in srv2 sends a curl request to srv1 to validate. I am always getting bool(false) when I print the curl response using var_dump. But if I am requesting for validation from my local wamp installation(localhost) it is perfectly returning the response. According to my understanding srv2 is blocking srv1 ip or something like that. Any help or suggestions will be greatly appreciated. The solution is really urgent as all my clients are stuck with invalid authorization message. Edit: Now when i tested curl in srv2 is working fine i think. Because I am able to fetch other websites without any trouble. But I am not able to fetch data from srv1. I can view a page from srv1 through browser url but not through curl.

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!

  • django: Selecting questions that was not asked

    - by Oleg Tarasenko
    Hi, I am creating small django application which holds some few questions (and answers for them) What I want to do is to show user random question, but only from those which was not solved by him yet. I wonder how to do this. For now, I defined user profile model this way: class UserProfile(models.Model): rank = models.IntegerField(default = 1) solvedQ = models.ManyToManyField(Question) user = models.ForeignKey(User, unique=True) So solved problems are added this way: if user.is_authenticated(): profile = user.get_profile() profile.rank += 1 profile.solvedQ.add(Question.objects.get(id=id)) Now if the view must show random question, but not from already solved list... Is there a good way to intersect Questions and solvedQuestions.... so question is chosen from the unsolved list?

  • Form authentication works on dev server but not on IIS

    - by Ilknur
    Hi, We have a similar problem. We have a web application running under default appdomain. It was working fine until a week before...Suddenly it has encountered a problem. Below message is taken from event logs. Event code: 4005 Event message: Forms authentication failed for the request. Reason: The ticket supplied has expired. Application uses FormsAuthentication and gets the roles from aspnetdb.. After the error, when user logins to the page, it does not redirects to the default.aspx. Again login.aspx comes up. On the other hand application works fine on development server(localhost), but not on www(IIS 6.0). Does any one has an idea? Thanks, Ilknur

Can anybody suggest me what can I do make it work? Thanks in advance... :)

  • jquery $.ajax not working in firefox against rails (406 response) (works in chrome & IE)

    - by phil swenson

  • xcopy not accepting a relative path as source parameter on certain computers

    - by slicedtoad
    xcopy /e /q ".\dlls\*.*" "%programfiles(x86)%\foo" >> TEMP xcopy /e /q dlls "%programfiles(x86)%\foo" >> TEMP xcopy /e /q ".\dlls" "%programfiles(x86)%\foo" >> TEMP All of the above work on two of my machines (windows 7 64bit). But on two peers' laptops (windows 7 64 bit and windows 8 64bit) they return file dlls not found or (in the case of the first one) file *.* not found Can someone shed some light here? The only difference I can see between the machines is possibly permissions. But I don't see how that would affect xcopy's ability to recognize a local path.

  • Finding parents where child collection does not contain an item

    - by Colin Bowern
    I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

  • Linq: comparison with nonexisting value should not cause the exception, but it does

    - by Seacat
    Hello, Given I don't know if the parameter will be null or not and I want to use it in the following way: if Param != null then compare with its id if Param == null then compare with null. Something like that: var c = from cat in context.Categories where ParamCat != null && cat.ParentId == ParamCat.Id || ParamCat == null && cat.ParentId == null select c; If ParamCat is null as soon as I try to get something from c (for example c.Count()) it throws the exception. Usually when we use some kind of condition it stop comparison as soon as condition fail especially if we use AND. For example this code will not cause any exception: if (ParamCat != null && cat.ParentId == RaramCat.Id) { } If so, why the linq code above throw exception? (Null reference) Thanks

  • NHibernate does not update entity when repository is passed by constructor

    - by Alex
    Hi everybody, I am developing with NHibernate for the first time in conjunction with ASP.NET MVC and StructureMap. The CodeCampServer serves as a great example for me. I really like the different concepts which were implemented there and I can learn a lot from it. In my controllers I use Constructur Dependency Injection to get an instance of the specific repository needed. My problem is: If I change an attribute of the customer the customer's data is not updated in the database, although Commit() is called on the transaction object (by a HttpModule). public class AccountsController : Controller { private readonly ICustomerRepository repository; public AccountsController(ICustomerRepository repository) { this.repository = repository; } public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customerToUpdate.GivenName = "test"; //<-- customer does not get updated in database return View(); } } On the other hand this is working: public class AccountsController : Controller { [LoadCurrentCustomer] public ActionResult Save(Customer customer) { customer.GivenName = "test"; //<-- Customer gets updated return View(); } } public class LoadCurrentCustomer : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { const string parameterName = "Customer"; if (filterContext.ActionParameters.ContainsKey(parameterName)) { if (filterContext.HttpContext.User.Identity.IsAuthenticated) { Customer CurrentCustomer = DependencyResolverFactory .GetDefault() .Resolve<IUserSession>() .GetCurrentUser(); filterContext.ActionParameters[parameterName] = CurrentCustomer; } } base.OnActionExecuting(filterContext); } } public class UserSession : IUserSession { private readonly ICustomerRepository repository; public UserSession(ICustomerRepository customerRepository) { repository = customerRepository; } public Customer GetCurrentUser() { var identity = HttpContext.Current.User.Identity; if (!identity.IsAuthenticated) { return null; } Customer customer = repository.GetByEmailAddress(identity.Name); return customer; } } I also tried to call update on the repository like the following code shows. But this leads to an NHibernateException which says "Illegal attempt to associate a collection with two open sessions". Actually there is only one. public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customer.GivenName = "test"; repository.Update(customerToUpdate); return View(); } Does somebody have an idea why the customer is not updated in the first example but is updated in the second example? Why does NHibernate say that there are two open sessions?

  • XamlXmlReader.Read() does not yield matching XamlNodeType.StartObject and XamlNodeType.EndObject on

    - by Yuval
    Hi, I am trying to parse a valid xaml file using the XamlXmlReader. It looks like it is 'skipping' some elements when when Read() is called. for example on the following xaml snippet: <UserControl.Resources> <Converters:AnyDbTypeToDisplayNameConverter x:Key="anyDbTypeToDisplayNameConverter" /> </UserControl.Resources> when reading I first get a XamlNodeType.StartObject on UserControl.Resources - makes sense then another XamlNodeType.StartObject on Converters - also cool. but then i do not get a XamlNodeType.EndObject on the Converters and immediately jump to the next line and does not report a XamlNodeType.StartObject. Any Idea if this is working as design ? looks like a bug to me

  • Dynamically load _gallery_ (not album) in SlideShowPro using SWFObject

    - by bccarlso
    Hi all. I have been successful in dynamically loading an album in SSP before, but using SSP Standalone. I did it like this: var flashvars = { xmlFilePath: "http://site.com/ssp_director/images.php?album=5" } What I'm looking to do now, though, is dynamically load a gallery when the page loads, using text entered in the javascript, or flashvars I'd assume. I'm using ActionScript 3 with this, so I'm not sure if I have to do something to the SSP instance in Flash. I'm not very good with AS3, so following advice or tutorials is about all I can muster. I'm also using SSP Director, so my gallery XML URLs would be similar to above in the example code. I'd be elated if this is possible, otherwise I will have to find an alternative solution. Thanks so much for help!

  • Ruby and jQuery -- $(document).ajaxSend() not modifying the params as expected

    - by Jason
    I cannot get jquery's ajaxSend (http://api.jquery.com/ajaxSend/) to properly modify the parameters. I have: $(document).ajaxSend(function(event, request, settings) { settings.data = $.deparam(settings.data); settings.data['random'] = new Date().getTime(); settings.data['_method'] = 'get'; settings.data = $.param(settings.data) $.log(settings); }); $(document).ready(function() { //...snip... $.ajaxSetup({ data : { remote : 1, authenticity_token : encodeURIComponent(AUTH_TOKEN) } }); }); The idea here is that we always want 4 param sent across: remote and auth_token always get set properly. However, random and _method (both needed for IE issues) do not get set. Logging settings inside ajaxSend shows me that they are set to settings.data: "remote=1&authenticity_token=6GA9R_snip_253D&random=1270584905846&_method=get" but when it gets sent across the wire, I only have the following: authenticity_token 6GA9R_snip_253D remote 1 Why in the world is this not working?
