  • Facebook Connect for iPhone persistant login

    - by Sam
    Hi, I have implemented Facebook Connect in my iPhone project and it is working great. The only problem I have is that every time the user closes the app, the next time they load it they have to re-enter their username and password to login even if the 'keep me logged in' box is checked. My question is is there a way to save the user's session so next time the app is launched they are automatically logged into Facebook Connect without any prompts? Thanks!

  • C# Select clause returns system exception instead of relevant object

    - by Kashif
    I am trying to use the select clause to pick out an object which matches a specified name field from a database query as follows: objectQuery = from obj in objectList where obj.Equals(objectName) select obj; In the results view of my query, I get: base {System.SystemException} = {"Boolean Equals(System.Object)"} Where I should be expecting something like a Car, Make, or Model Would someone please explain what I am doing wrong here? The method in question can be seen here: // this function searches the database's table for a single object that matches the 'Name' property with 'objectName' public static T Read<T>(string objectName) where T : IEquatable<T> { using (ISession session = NHibernateHelper.OpenSession()) { IQueryable<T> objectList = session.Query<T>(); // pull (query) all the objects from the table in the database int count = objectList.Count(); // return the number of objects in the table // alternative: int count = makeList.Count<T>(); IQueryable<T> objectQuery = null; // create a reference for our queryable list of objects T foundObject = default(T); // create an object reference for our found object if (count > 0) { // give me all objects that have a name that matches 'objectName' and store them in 'objectQuery' objectQuery = from obj in objectList where obj.Equals(objectName) select obj; // make sure that 'objectQuery' has only one object in it try { foundObject = (T)objectQuery.Single(); } catch { return default(T); } // output some information to the console (output screen) Console.WriteLine("Read Make: " + foundObject.ToString()); } // pass the reference of the found object on to whoever asked for it return foundObject; } } Note that I am using the interface "IQuatable<T>" in my method descriptor. An example of the classes I am trying to pull from the database is: public class Make: IEquatable<Make> { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Model> Models { get; set; } public Make() { // this public no-argument constructor is required for NHibernate } public Make(string makeName) { this.Name = makeName; } public override string ToString() { return Name; } // Implementation of IEquatable<T> interface public virtual bool Equals(Make make) { if (this.Id == make.Id) { return true; } else { return false; } } // Implementation of IEquatable<T> interface public virtual bool Equals(String name) { if (this.Name.Equals(name)) { return true; } else { return false; } } } And the interface is described simply as: public interface IEquatable<T> { bool Equals(T obj); }

  • How to get the EJB listening port?

    - by Alotor
    I'm currently developing a library for monitoring calls to several remote services (WebServices, EJBs...). One of the parameters that i would like to register is the port from which a EJB is called (a Stateless Session Bean invoked like a remote object) There is any standarised way of getting the port? Or should I inspect the JNDI tree for this kind of information? I'm using the EJB 2.1 spec, but it's also posible for me to use EJB 3

  • Sign out button reloads all user controls

    - by eych
    I have an aspx page with several user controls (ascx) as well as an asp:button for signing out. The click event of the button clears the session and does a response.redirect to the login page. However, before the click event is called, since the page posts back, all of the Page_Load events run for all of the controls. What is the best way to have the click event code run without unnecessary reloading of all user controls?

  • closing MQ connection

    - by OakvilleWork
    Good afternoon, I wrote a project to Get Park Queue Info from the IBM MQ, it has producing an error when attempting to close the connection though. It is written in java. Under application in Event Viewer on the MQ machine it displays two errors. They are: “Channel program ended abnormally. Channel program ‘system.def.surconn’ ended abnormally. Look at previous error messages for channel program ‘system.def.surconn’ in the error files to determine the cause of the failure. The other message states: “Error on receive from host rnanaj (10.10.12.34) An error occurred receiving data from rnanaj (10.10.12.34) over tcp/ip. This may be due to a communications failure. The return code from tcp/ip recv() call was 10054 (X’2746’).

  • CC.NET + SVN : Server certificate issue

    - by MSI
    I am trying to setup Continuous Integration in our office. Being a puny little developer I am facing this supposedly infamous problem: " Source control operation failed: svn: OPTIONS of 'https://trunkURL': Server certificate verification failed: issuer is not trusted" So I tried the following solution - Run CC.NET service (server running as win service) using a domain account (rather than default LOCAL SYSTEMS) and accept cert permanently using command prompt under that user by using svn log/list on the repo. Doesn't help :(. I am getting the following from my artifact/log files(or dashboard) ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'https://TrunkURL': Server certificate verification failed: issuer is not trusted (https://ServerAdd) .

  • Remove stateful EJB bean in client

    - by palto
    I'm currently learning EJB and as I understand when client gets a stateful session bean the server keeps it in memory(or passivates it) until the client removes the bean. Pretty simple, except nowhere I have seen any examples of how the client can actually remove the bean. How do you do that other than shutting down your client application? Or do I just have to implement a reset method in all my stateful beans if I want to start over?

  • How to integrate Windows Azure, Spring.NET and NHibernate?

    - by paologios
    Hi, we have a ASP.NET web application which makes use of NHibernate and Spring.NET (to do the session and transaction management stuff). Now we want to port parts of it to a Windows Azure application without making lots of changes to the used components. I already found this article of stackoverflow so I hope to get NHibernate running on Azure. My question: Has anybody experiences in running Spring.NET on Azure (with or without NHibernate) ??

  • CSRF protection and cross site form access

    - by fl00r
    Hi. I aw working on cross site authentication (some domains have got common authentication). So I want to send authentication data (login, password) to main domain from others. How should I use protect_from_forgery and how can I check if data received from valid domain? What I am thinking now is to turn off protect_from_forgery for session controller and check domain name of received data. But maybe I can configure CSRF protection for not only one domain?

  • Mysql concurrency: what happens if a locked table is accessed?

    the question is rather simple but I couldn't find a precise answer: in a myisam db, what happens if a php file locks a table (with an atomic operation, say an INSERT) and another php file tries to access the same table (reading or writing)? Now, while it is obvious that the second session will not be able to access the table, what exactly happens? Does it return some kind of error? Does is wait in queue until it is able to access it? Thanks in advance!

  • ksh Auto-Completion PuTTY Configuration

    - by Nitrodist
    I'm having a bit of a problem configuring my PuTTY client to work with the auto-completion feature in the ksh shell. I do a listing on the root with the directories /home and /homeroot and it returns the directories in a list just fine. I can't select it, though, by hitting X = (where X is the number). /home/nitrodist>ls /h #hits esc + = 1) home/ 2) homeroot/ #hits 2 + = for the 'homeroot' dir 1) home/ 2) homeroot/ #hits just the '=' key. 1) home/ 2) homeroot/ Any ideas? I've su -'d to another user who can actually do it with their PuTTY session and I can't do it there, which makes me think it's a PuTTY configuration issue. This is running on a ksh93 shell on HP-UX, if that makes any difference. Here's my ksh config: /home/campbelm>set -o Current option settings allexport off bgnice on emacs off errexit off gmacs off ignoreeof off interactive on keyword off markdirs off monitor on noexec off noclobber off noglob off nolog off notify off nounset off privileged off restricted off trackall off verbose off vi on viraw on xtrace off /home/campbelm>

  • How can I ignore an http request without clearing the browser?

    - by Timid Developer
    To prevent duplicate requests (i.e. pressing F5 right after clicking a command button), I've setup my page base class to ignore the request if it's detected as a duplicate. When I say 'ignore' I mean Response.End() Now I thought I've seen this work before, where there's an issue, I just Response.End() and the users page just does nothing. I don't know the exact circumstance in which this worked, but I'm unable to repeat it now. Now when I call Response.End(), I just get an empty browser. More specifically, I get this html. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> I setup the following test app to confirm the problem is not elsewhere in my app. Here it is: Add the following to an aspx form <asp:Label ID="lbl" Text="0" runat="server" /><br /> <asp:Button ID="btnAdd1" Text="Add 1" runat="server" /><br /> <asp:Button ID="btnAdd2" Text="Add 2" runat="server" /><br /> <asp:Button ID="btnAdd3" Text="Add 3" runat="server" /><br /> And here's the code behind file using System; namespace TestDupRequestCancellation { public partial class _Default : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { btnAdd1.Click += btnAdd1_Click; btnAdd2.Click += btnAdd2_Click; btnAdd3.Click += btnAdd3_Click; } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) CurrentValue = 0; else if (Int32.Parse(lbl.Text) != CurrentValue) Response.End(); } protected void Page_PreRender(object sender, EventArgs e) { lbl.Text = CurrentValue.ToString(); } protected int CurrentValue { get { return Int32.Parse(Session["CurrentValue"].ToString()); } set { Session["CurrentValue"] = value.ToString(); } } void btnAdd3_Click(object sender, EventArgs e) { CurrentValue += 3; } void btnAdd2_Click(object sender, EventArgs e) { CurrentValue += 2; } void btnAdd1_Click(object sender, EventArgs e) { CurrentValue += 1; } } } When you load the page, clicking any button does what is expected, but if you press F5 at any time after pressing one of the buttons, it will detect it as a duplicate request and call Response.End() which promptly ends the task. Which leaves the user with an empty browser. Is there anyway to leave the user with the page as it was, so they can just click a button? Also; please note that this code is the simplest code I could come up with to demonstrate my problem. It's not meant to demonstrate how to check for dup requests.

  • How can you remove a criterion from criteria?

    - by ChuckM
    Hello, For instance if I do something like: Criteria c = session.createCriteria(Book.class) .add(Expression.ge("release",reDate); .add(Expression.ge("price",price); .addOrder( Order.asc("date") ) .setFirstResult(0) .setMaxResults(10); c.list(); How can I use the same criteria instance, but remove (for example) the second criterion? I'm trying to build a dynamic query in which I'd like to let the user remove a filter, without the backend having to reconstruct the criteria from scratch. Thank you
