    - by Nicole
    Hi everyone!! I have a MVC website and when I execute it, the query string (url) that appears is: http://localhost:6970/(S(51aegi45qneolxa0oxwuzh55))/default.aspx what the hell is that strange combination of numbers and letters??? please help!!!!! previously i had been working with the session expires to redirect to one of my views, could be something of that?? i have added the following action filter: public override void OnActionExecuting(ActionExecutingContext filterContext) { HttpContextBase ctx = filterContext.HttpContext; // check if session is supported if (ctx.Session != null) { // check if a new session id was generated if (ctx.Session.IsNewSession) { // If it says it is a new session, but an existing cookie exists, then it must // have timed out string sessionCookie = ctx.Request.Headers["Cookie"]; if ((null != sessionCookie) && (sessionCookie.IndexOf("ASP.NET_SessionId") >= 0)) { filterContext.HttpContext.Response.Redirect("~/Error/SesionExpirada", true); } } } base.OnActionExecuting(filterContext); } but if I put it in ignore it stills add that rare thing to my urls. Please help!!! thanks

  • Is this state-of-the-art Ajax/jQuery, or should I do it differently?

    - by AP257
    Hi everyone: I'm using Ajax and jQuery to do some cool client-side stuff. Basically, if the user chooses a subject from a from a drop-down list, I want to auto-populate the page with a set of book details. However, I've built the Ajax from Google results and bits of string. I don't know if what I've done is up-to-date, or whether there are now much neater ways of doing it! Here's what I have: can it be improved? $("#subjectlist").change(function() { if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { var book_details = eval(xmlhttp.responseText); alert(book_details[0]["url"]); // To be added: extra code to populate HTML results. document.getElementById("book_results").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","/subject_json/?id=" + $("#subjectlist").val(),true); xmlhttp.send(); }); Thanks for any advice!

  • Most secure way to generate a random session ID for a cookie?

    - by ensnare
    I'm writing my own sessions controller that issues a unique id to a user once logged in, and then verifies and authenticates that unique id at every page load. What is the most secure way to generate such an id? Should the unique id be completely random? Is there any downside to including the user id as part of the unique id?

  • Fragment savedInstanceState is always null (Android support lib)

    - by Evgeny Egorov
    I wrote a simple test project, but I cant understand why I always receive savedInstanceState = null in lifecycle methods onCreate, onCreateView and onActivityCreated. I change the screen orientation, see the log, but state not saved. Tell me please where is my mistake. Thanks. The code of fragment class is: public class TestFragment extends Fragment { private String state = "1"; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (savedInstanceState != null) { //never works state = savedInstanceState.getString("state"); } //always prints 1 Toast.makeText(getActivity(), state, Toast.LENGTH_SHORT).show(); return inflater.inflate(R.layout.fragment_layout, container, false); } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("state", "2"); Log.e("", "saved 2"); } }

  • How do I combine similar method calls into a delegate pattern?

    - by Daniel T.
    I have three methods: public void Save<T>(T entity) { using (new Transaction()) { Session.Save(entity); } } public void Create<T>(T entity) { using (new Transaction()) { Session.Create(entity); } } public void Delete<T>(T entity) { using (new Transaction()) { Session.Delete(entity); } } As you can see, the only thing that differs is the method call inside the using block. How can I rewrite this so it's something like this instead: public void Save<T>(T entity) { TransactionWrapper(Session.Save(entity)); } public void Create<T>(T entity) { TransactionWrapper(Session.Create(entity)); } public void Save<T>(T entity) { TransactionWrapper(Session.Save(entity)); } So in other words, I pass a method call as a parameter, and the TransactionWrapper method wraps a transaction around the method call.

  • Which .NET exception to throw for invalid database state?

    - by jslatts
    I am writing some data access code and I want to check for potentially "invalid" data states in the database. For instance, I am returning a widget out of the database and I only expect one. If I get two, I want to throw an exception. Even though referential integrity should prevent this from occurring, I do not want to depend on the DBAs never changing the schema. I would like to use the System.IO.InvalidDataException, except that I am not dealing with a file stream so it would be misleading. I ended up going with a generic applicationexception. Anyone have a better idea?

  • What's the state of PHP unit testing frameworks in 2010?

    - by Pekka
    As far as I can see, PHPUnit is the only serious product in the field at the moment. It is widely used, is integrated into Continuous Integration suites like phpUnderControl, and well regarded. The thing is, I don't really like working with PHPUnit. I find it hard to set up (PEAR is the only officially supported installation method, and I hate PEAR), sometimes complicated to work with and, correct me if I'm wrong, lacking executability from a web page context (i.e. no CLI, which would really be nice when developing a web app.) The only competition to I can see is Simpletest, which looks very nice but hasn't seen a new release for almost two years, which tends to rule it out for me - Unit Testing is quite a static field, true, but as I will be deploying those tests alongside web applications, I would like to see active development on the project, at least for security updates and such. There is a SO question that pretty much confirms what I'm saying: Simple test vs PHPunit Seeing that that is almost two years old as well, though, I think it's time to ask again: Does anybody know any other serious feature-complete unit testing frameworks? Am I wrong in my criticism of PHPUnit? Is there still development going on for SimpleTest?

  • Current state of Erlang web development? Frameworks, Template languages

    - by pommonico
    Django is to Python as Rails is to Ruby. What is the current front-runner for Erlang? Recent Erlang web activity has resulted in many new frameworks but they are all still moving targets. ErlyWeb is very far along but now seems to be dead. If you were to invest significant capital into a new web product (i.e. not a hobby, you use your own money and you use other's investment in you with expectation of payback), would you choose Erlang as a web platform? If so, what framework and technologies would you choose?

  • How does dzone.com maintain state of the div?

    - by CShipley
    When you scroll down to the bottom of http://www.dzone.com/links/ it automatically loads more links. However, when you navigate away, then hit the back button, the contents of the modified div stay there. How do they get the browser to go back to a dynamically generated div?

  • How to improve the speed of a loop containing a sqlalchemy query statement as conditional

    - by LtPinback
    This loop checks if a record is in the sqlite database and builds a list of dictionaries for those records that are missing and then executes a multiple insert statement with the list. This works but it is very slow (at least i think it is slow) as it takes 5 minutes to loop over 3500 queries. I am a complete newbie in python, sqlite and sqlalchemy so I wonder if there is a faster way of doing this. list_dict = [] session = Session() for data in data_list: if session.query(Class_object).filter(Class_object.column_name_01 == data[2]).filter(Class_object.column_name_00 == an_id).count() == 0: list_dict.append({'column_name_00':a_id, 'column_name_01':data[2]}) conn = engine.connect() conn.execute(prices.insert(),list_dict) conn.close() session.close() edit: I moved session = Session() outside the loop. Did not make a difference.

  • When should I think about implementing my User authentication / session?

    - by Jason N
    After spending some time wireframing my ideas, I want to start building my rails app. However, I'm well aware that later down the line I'd like to consider multiple user accounts. Should I be thinking about the implementation of this from this early stage, or is this something I can implement without too much fuss later? It seems like something that would be stupid to attempt later, but part of me just wants to get the guts of the thing working - a couple of simply forms and writing/reading some stuff from the db.

  • Can a webflow's action state have multiple redirects on success?

    - by callie16
    Say, I have this type of webflow: def myFlow = { state1 { } on("next").to("stateAct") stateAct { action { ... DB stuff ... } } on("success").to("state2") state2 { } on("prev").to("state1") } Now, the contents of "stateAct" is common between state1 and state2. Meaning, if I press "next" from state1, I need to pass by stateAct before I can go to state2 (which is the current implementation) and if I press "prev" in state2, I need it to pass by stateAct before it goes to state1. Obviously, in the sample webflow above, it doesn't do the latter. So, my question is, is there a way to detect in stateAct who called it (state1 or state2) so that I can redirect accordingly on "success"? Or something similar to that behavior? Thanks! -Lee

  • What happens when you create an instance of an object containing no state in C#?

    - by liquorice
    I am I think ok at algorithmic programming, if that is the right term? I used to play with turbo pascal and 8086 assembly language back in the 1980s as a hobby. But only very small projects and I haven't really done any programming in the 20ish years since then. So I am struggling for understanding like a drowning swimmer. So maybe this is a very niave question or I'm just making no sense at all, but say I have an object kind of like this: class Something : IDoer { void Do(ISomethingElse x) { x.DoWhatEverYouWant(42); } } And then I do var Thing1 = new Something(); var Thing2 = new Something(); Thing1.Do(blah); Thing2.Do(blah); does Thing1 = Thing2? does "new Something()" create anything? Or is it not much different different from having a static class, except I can pass it around and swap it out etc. Is the "Do" procedure in the same location in memory for both the Thing1(blah) and Thing2(blah) objects? I mean when executing it, does it mean there are two Something.Do procedures or just one?

  • how to verify that an old session is really destroyed?

    - by jodeci
    Um, this might sound a bit weird. We were having some problems with a specific browser under a very specific condition, and finally narrowed down the problem to the fact that we were not properly destroying the old sessions after doing session_regenerate_id(). I believe I have solved this problem by doing session_regenerate_id(true) now, but how does one verify that the previous sessions really do not exist any more? Someone suggested cURL but I cannot find my way around their docs. Sadly(?) the boss does not take 'it just works' for an answer so I'd really appreciate any advice!

  • Can I set JFrame's normal size while it is maximized?

    - by icza
    I'd like to set the normal size of a visible JFrame while it is in Frame.MAXIMIZED_BOTH state (by normal size i mean the size of frame when it is in Frame.NORMAL state) . The reason I want to do this is so that when the user un-maximizes the frame, it will have the proper size I want it to be. But if I do so, the window will switch to normal state. If I set the size first, then switch to MAXIMIZED_BOTH state, then I will see a disturbing blink or resize (which I don't want to). I've also tried setting the size first, then changing state to MAXIMIZED_BOTH, and then making it visible, but the state change is deferred if the window is not visible (and will only be executed once it is made visible, also resulting in a visual resize). So what can I do if I want my frame to have a predefined normal size, but I want it to appear maximized?

  • What's the current (as of April 2010) state of affairs regarding <object> vs <embed> in HTML?

    - by rvdm
    The age old question. <object> vs <embed>. From what I gather, <object> is the XHTML-compliant way of doing things, while <embed> is for legacy support. I'm currently building a Flash application that will contain a pre-made embedding code for users to copy and paste, and I'm wondering if it's feasible to simply dump the <embed> tag altogether. Which browsers would be unable to load my application if I gave my users an <object>-only embed code? Thanks :)

  • Can't get a List(Of <my class>) from a Dictionary in .NET?

    - by magsto
    I have a Dictionary with key of type UInteger and the value is List(Of Session) where the (Public) class Session contains a couple of variables and a constructor (Public Sub New(...)). Some of the variables in my Session class is: Private count As Integer Private StartDate As Date Private Values As List(Of Integer) and a couple of methods like: Friend Sub Counter(ByVal c as Integer) count += c End Sub There is no problem to add values to the Dictionary: Dim Sessions As New List(Of Session) Dim dict As New Dictionary(Of Integer, Sessions) then some code to fill up a couple of Session objects in Sessions (not shown here) and then: dict.Add(17, Sessions) 'No problem Sessions.Clear() Sessions = dict(17) 'This doesn't return anything! The Sessions object is empty even if the code doesn't returned any error. Is my class Session to compex to be stored in a Dictionary?
