  • Using a Session Scoped Bean

    - by jboyd
    The following code is returning null: private MyAppUser getMyAppUser(HttpSession session) { MyAppUser myAppUser = (MyAppUser) session.getAttribute("myAppUserManager"); return myAppUser; } Despite the fact that I have the following in my context: <bean id="myAppUserManager" class="com.myapp.profile.MyAppUser" scope="session"/> This doesn't make any sense to me, the "myAppUser" bean is a bean that absolutely can never be null, and I need to be able to reference it from controllers, I don't need it in services or repositories, just controllers, but it doesn't seem to be getting stored in the session, the use case is extremely simple, but I haven't been able to get to the bottom of what's wrong, or come up with a good workaround

  • Static Variables in Overloaded Functions

    - by BSchlinker
    I have a function which does the following: When the function is called and passed a true bool value, it sets a static bool value to true When the function is called and passed a string, if the static bool value is set to true, it will do something with that string Here is my concern -- will a static variable remain the same between two overloaded functions? If not, I can simply create a separate function designed to keep track of the bool value, but I try to keep things simple.

  • Setting current culture with threads in ASP.NET MVC

    - by mare
    Here's an example of SetCulture attribute which inside does something like this: public void OnActionExecuting(ActionExecutingContext filterContext) { string cultureCode = SetCurrentLanguage(filterContext); if (string.IsNullOrEmpty(cultureCode)) return; HttpContext.Current.Response.Cookies.Add( new HttpCookie("Culture", cultureCode) { HttpOnly = true, Expires = DateTime.Now.AddYears(100) } ); filterContext.HttpContext.Session["Culture"] = cultureCode; CultureInfo culture = new CultureInfo(cultureCode); System.Threading.Thread.CurrentThread.CurrentCulture = culture; System.Threading.Thread.CurrentThread.CurrentUICulture = culture; } I was wondering how does this affect a site with multiple users logged on and each one setting their own culture? What is the scope of a thread here with regards to the IIS worker process (w3wp) that the site is running in?

  • Get the closest number

    - by user183089
    Hi, i am implementing a little Black Jack game in C# and i have the following problem calculating the player's hand value. the problem is Ace may have value of 1 or 11 so if the players has three cards and one Ace if the sum of the cards is <= 10 Ace will have value of 11(Sorry for who doesn't know the scope of the game is to reach 21 with the sum of the cards) Other way value of 1 Up to here is easy Now lets assume i do not know how many Aces the player has got and the game is implemented giving the possibility to the dealer to use more than one deck of cards. the user may have in one hand even 5,6,7,8 ... aces. What is the best way(possibly using Linq) to evaluate all the aces the player has got to get the closest combination to 21 (in addition tot he other cards)? I hope i have been clear thanks for your help.

  • How do I find useful code previously deleted but still stored in source control?

    - by sharptooth
    Whenever someone asks what to do with code that is no longer needed the answer is usually "delete it, restore it from source control if you need it back". Now how do I find that piece of source code in the repository? Let's limit scope to SVN for simplicity - I suspect that using any other source control system will not make much difference in this aspect (correct me if I'm wrong). If I delete that code and commit the changes it will no longer be in the latest revision. How do I find it without exporting each revision and searching thoroughly (which is nearly impossible)?

  • Reading from a oracle temp table in a separate procedure than the one it was populted in

    - by Bob
    I have a 2 stored procedures, the first creates an oracle temp table and the second reads from it. The temp table only has scope for that session. I'm calling the procedures from .Net and the second procedure never returns any results. However if I use the same sprocs and parameters in SQL*Plus it works fine. I've tried creating an Oracle Transaction object and had hoped I'd be able to read the tables in while still using the same transaction - trying to emulate an SQL Plus type of single connection environment. Any ideas what I'm doing wrong??

  • What is the ratio of Java programmers to C#.net programmers?

    - by Vaccano
    How many Java Programmers are there to every C# programmer? I have a coworker that says it was 3:1 (3 Java to 1 C#) but it is now more like 2:1 (2 java to 1 C#) Is this valid? Is there somewhere I could go for this info? Edit: This question needs to be a bit more limited in scope. I am referring to US programmers and those who would consider their career to be more focused in one side than the other. (If you are evenly balanced then you would cancel out.)

  • Pylons and Facebook

    - by Nayan Jain
    The following is my oauth template top.location.href='https://graph.facebook.com/oauth/authorize?client_id=${config['facebook.appid']}&redirect_uri=${config['facebook.callbackurl']}&display=page&scope=publish_stream'; Click here to authorize this application When I hit the page I am prompted to login (desired), upon login I am redirected in a loop between a permissions page and an app page. My controller looks like: class RootController(BaseController): def __before__(self): tmpl_context.user = None if request.params.has_key('session'): access_token = simplejson.loads(request.params['session'])['access_token'] graph = facebook.GraphAPI(access_token) tmpl_context.user = graph.get_object("me") def index(self): if not tmpl_context.user: return render('/oauth_redirect.mako') return render('/index.mako') I'm guessing my settings are off somewhere, probably with the callback. Not to sure if it is an issue with my code or the python sdk for facebook.
