  • findManyToManyRowset with Zend_Db_Table_Select

    - by Typeoneerror
    Hello. I'm trying to use a select object to filter the results of a many to many rowset. This call works great: $articles = $this->model->findArticlesViaArticlesUsers(); This however does not: $articles = new Default_Model_Articles(); $articleSelect = $articles->select(); $articleSelect->where("status = 'published'") ->order("date_published DESC") ->limit(1); $articles = $this->model->findArticlesViaArticlesUsers($articleSelect); That throws the following error: exception 'Zend_Db_Select_Exception' with message 'You cannot define a correlation name 'i' more than once' I can't figure out how to successfully get "articles that have the status of 'published'" using the magic many-to-many relationship (nor findManyToManyRowset). I'm at the end of my rope and thinking of just writing the sql manually. Any ideas?

  • Which layer should create DataContext?

    - by Kevin
    I have a problem to decide which layer in my system should create DataContext. I have read a book, saying that if do not pass the same DataContext object for all the database updates, it will sometimes get an exception thrown from the DataContext. That's why i initially create new instance of DataContext in business layer, and pass it into data access layer. So that the same datacontext is used for all the updates. But this lead to one design problem, if i wanna change my DAL to Non-LinqToSQL in future, i need to re-write the code in business layer as well. Please give me some advice on this. Thanks. Example code 'Business Layer Public Sub SaveData(name As String) Using ts AS New TransactionScope() Using db As New MyDataContext() DAL.Insert(db,name) DAL.Insert(db,name) End Using ts.Complete() End Using End Sub 'Data Access Layer Public Sub Insert(db as MyDataContext,name As string) db.TableAInsert(name) End Sub

  • Attachment_fu error

    - by cswebgrl
    Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

  • Silverlight Cannot find XML data source

    - by Nick
    Hello.. I am very new to Silverlight development. I understand that this is client side technology therefore the paradyme is differant from that of conventional ASP.NET development. Having said that, I don't understand where my server side code is deployed. I have a silver light \ MVC application. I am trying to read an XML document from within my 'Models' folder. The following peice of code is executed from within a class that is in the same location as the XML document, 'Models'. The load() results in a SystemIOFileNotFound exception. I noticed that when building the application the XML document is not laid down in the same location as the web project's assembly. I assume this is specific to the fact that this is a Silverlight project. Can someone tell me what I'm missing? _xdoc = new XDocument(); _xdoc = XDocument.Load(new Uri("videos.xml",UriKind.Relative).ToString());

  • Authkit - deferring action for HTTP '401' response to client application

    - by jon
    Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

  • Unable to load assembly with windows service

    - by Brian
    I have created a windows service in C# VS2008 that uses a reference to an external class library to wrote. I have added the reference to it in VS2008. When I run start the service it throws an exception when trying to access the external DLL: Could not load file or assembly 'vcribAPI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. The DLL is in the same directory as the service.exe file. Is there something special that I need to do for windows services like putting the DLL in another directory?

  • Python.expat can't parse XML file with bad symbols. How to go around?

    - by culebrón
    I'm trying to parse an XML file with expat, and here's the line where I get bad token exception: <tag k="name" v="???????????????????????????????????????????????????????????????????" /> xml.parsers.expat.ExpatError: not well-formed (invalid token): line 610127, column 37 The symbols in hex look like: \xd1? Seems like someone wrote this string (Russian alfabet) hitting backspace a few times. I set parser.returns_unicode = True, but this didn't help. The 1st line is <?xml version="1.0" encoding="UTF-8"?>. I work with a bz2 file. (bz2.BZ2File) How can I parse the file?

    - by VJ
    I want to add my own session variable to elmah error log table and display it. I already have modified the source code and added the new fields to Error.cs and other fields but I don't know but when I assign an HttpContext.Current.Session["MyVar"].tostring() value to my field in the constructor it stops logging exceptions and does not log any exception. I just need to get the value of the session variable is there other way for this. I read a post which he added fields for the email but it does not say where exactly should I get the session value.

  • Bug in the official Android Fragments training sample?

    - by Jeff Axelrod
    It seems to me that there must be a bug in the Android Fragments demo. As background, Fragments are apparently sometimes instantiated by the Android OS and thus need a public no-arg constructor: All subclasses of Fragment must include a public empty constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the empty constructor is not available, a runtime exception will occur in some cases during state restore. But the NewsReader demo from the official Android training on Fragments constructs the HeadlinesFragment class and configures it with setOnHeadlineSelectedListener(this) from NewsReaderActivity.onCreate(). If the Android OS re-instantiates this fragment, the mHeadlineSelectedListener field will be null because HeadlinesFragment doesn't save or restore its state. Is this a bug or am I missing something?

  • adding model validation errors in rescue

    - by ash34
    I have the following model with a virtual attribute class Mytimeperiod < ActiveRecord::Base validates presence of :from_dt validates_format_of :from_dt, :with => /\A\d{2}\/\d{2}\/\d{4}\Z/, :message => "format is mm/dd/yyyy" def from_dt self.from_date.strftime("%m/%d/%Y") if !self.from_date.blank? end def from_dt=(from_dt) self.from_date = Date.parse(from_dt) rescue self.errors.add_to_base("invalid from dt") end end I am using <%= f.error_messages %> to display the error messages on the form. I am using from_dt as a virtual attribute (string). The 'presence of' and 'format of' validation errors show up on the form, but when the user enters an invalid date format on the form and Date.Parse raises an exception I have a 'errors.add_to_base' statement in the rescue clause. Can anyone tell me why this error does not show up in the form error messages when I disable the 'format of' validation. thanks.

    - by Marcin
    Hi guys I have a weird problem with mysqli timeout options, here you go: I am using mysqli_init() and real_connect() in order to set MYSQLI_OPT_CONNECT_TIMEOUT $this->__mysqli = mysqli_init(); if(!$this->__mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT,1)) throw new Exception('Timeout settings failed') $this->__mysqli->real_connect(host,user,pass,db); .... Then I am initiating query on locked table (LOCKE TABLE users WRITE) and its just hanging, ignoring all my settings even: set_time_limit(1); ini_set('max_execution_time',1); ini_set('default_socket_timeout',1); ini_set('mysql.connect_timeout',1); I understand why set_time_limit(1) and max_execution_time is ignored but why other timeouts and especially MYSQLI_OPT_CONNECT_TIMEOUT are ignored and how to solve it. I am using PHP 5.3.1 on Windows and Linux boxes, please help.

  • ASP.NET MVC as a service host for SOA like architecture

    - by Delucia
    I'm creating a distributed application that includes a lot of services and I'm looking for the technology that allows me to create and manage a lot of services easily. I know managing and deploying windows services is not fun. I'm thinking of using ASP.NET MVC as service host of my services where each controller action becomes essentially a service and I can communicate with a service via simple HTTP request and responses and not have to deal with complexity if i use something like WCF. Services need to be isolated and asp.net requests are isolated as far as i know, i.e. if a request throws an exception it will not effect other running requests. But I still have questions about the management of the services. How will it be possible to see which services are running, stopping and resuming services. Also ASP.NET MVC are passive, i.e. they only do something upon a request but what if i want to service that initiates work by itself?

  • Gmail freezes on display:none

    - by kambamsu
    Hi, I have a "div" which i insert in everypage, inside which resides my plugin. In certain pages where i might not need to use the plugin, i do a display:none on the div. This seems to work perfectly fine in all browsers. The only exception to this seems to be the "google.com" pages. Whether it be the search page or the gmail page, it seems to freeze once i do this display:none. By freeze i mean that none of the links are clickable after this. Is there something specific with these pages that i'm missing?? Any help would be appreciated. Thanks

  • Can I check wheter Linq 2 SQL's DataContext is tracking entities?

    - by Thomas Jespersen
    We want to throw an exception, if a user calls DataContext.SubmitChanges() and the DataContext is not tracking anything. That is... it is OK to call SubmitChanges if there are no inserts, updates or deletes. But we want to ensure that the developer didn't forget to attach the entity to the DataContext. Even better... is it possible to get a collection of all entities that the DataContext is tracking (including those that are not changed)? PS: The last question I asked were answered with: "do it this way instead"... please don't :-)

  • Blank space after file extension -> weird FileInfo behaviour

    - by Axarydax
    Somehow a file has appeared in one of my directories, and it has space at the end of its extension - its name is "test.txt ". The weird thing is that Directory.GetFiles() returns me the path of this file, but I'm unable to retrieve file information with FileInfo class. The error manifests here: DirectoryInfo di = new DirectoryInfo("c:\\somedir"); FileInfo fi = di.GetFileSystemInfos("test*")[0] as FileInfo; //correctly fi.FullName is "c:\somedir\test.txt " //but fi.Exists==false (!) Is FileInfo class broken? Can I somehow retrieve information about this file? I really don't know how did that file appear on my file system, and I am unable to recreate some more of them. All of my attempts to create a new file with this type of extension have failed, but now my program is crashing when encoutering it. I can easily handle the exception when finding the file, but boy am I curious about this!

  • How to calculate a RTOS task's time

    - by Adnan
    Hello all, I have written a code in c for Arm7 using RTOS. There are multiple tasks who's priority is set to same level. So the tasks executes on round-robin base. There is an exception that one task (Default) has set to lower priority then the other task in rtos. So that if no task is running, the default or lower priority task runs. Now i want to calculate the exact total timing (time duration) for that default task runs. Can any one give some idea what to do .... and how to do in code.. Regards Dani

  • unable to find an entry point named 'interlockedexchange'

    - by Miki Amit
    Hi , I built an application in c# vs2005 .net . Everything works fine when i run the application in win 32 bit, But when running the application in win 64 it crashes while trying to call the pinvoke interlockedexchange(which is within the kernel32.dll) function . This is the exception : unable to find an entry point named 'interlockedexchange' I didnt find the interlockedexchange function within the kernel32.dll under system32 directory but it was found under the syswow64 directory(in the kernel32.dll) . I guess that the .net runtime is configured to the system32 directory and not to the syswow64 . How is it possible to change this configuration ? Can you think of any other problem that could cause this? any help would be appreciated! thanks , Miki Amit

  • Using RouteExistingFiles to block access to existing files even if no route exists

    - by Michael Stum
    In ASP.net MVC 2, I can use routes.RouteExistingFiles = true; to send all requests through the routing system, even if they exist on the file system. Usually, this ends up hitting the "{controller}/{action}/{id}" route and throws an exception as the controller cannot be found. I do not want to use that route though (I have only a few URLs and they are specifically mapped), yet I would still like to prevent access to the file system. Basically I want to Whitelist pages using IgnoreRoute. Is there a built-in way to do this? My current approach is to still have the "{controller}/{action}/{id}" route and generate a 404 when this is hit, but I'm just wondering if something is built-in already?

  • How Can I Check an Object to See its Type and Return A Casted Object

    - by Russ Bradberry
    I have method to which I pass an object. In this method I check it's type and depending on the type I do something with it and return a Long. I have tried every which way I can think of to do this and I always get several compiler errors telling me it expects a certain object but gets another. Can someone please explain to me what I am doing wrong and guide me in the right direction? What I have tried thus far is below: override def getInteger(obj:Object) = { if (obj.isInstanceOf[Object]) null else if (obj.isInstanceOf[Number]) (obj:Number).longValue() else if (obj.isInstanceOf[Boolean]) if (obj:Boolean) 1 else 0 else if (obj.isInstanceOf[String]) if ((obj:String).length == 0 | (obj:String) == "null") null else try { Long.parse(obj:String) } catch { case e: Exception => throw new ValueConverterException("value \"" + obj.toString() + "\" of type " + obj.getClass().getName() + " is not convertible to Long") } }

  • Problem with SqlServer 2005 when opening connections

    - by Jose Obregon
    I have a Winforms application and I use EntLib to connect to a SQL Server 2005 DB. The application is working ok, but sometimes, and lately more often, we have started receiving this error from the db when opening the connection: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) The problem is intermittent. The user works well for a couple of hours and then suddenly the exception is thrown. Sometimes it happens when we run a small process that loads a file and then inserts the data to the db.

  • ProcessCmdKey - wait for KeyUp?

    - by Tom Frey
    Hi, I'm having the following issue in a WinForms app. I'm trying to implement Hotkeys and I need to process Key messages whenever the control is active, no matter if the focus is on a textbox within that control, etc. Overriding ProcessCmdKey works beautifully for this and does exactly what I want with one exception: If a user presses a key and keeps it pressed, ProcessCmdKey keeps triggering WM_KEYDOWN events. However, what I want to achieve is that the user has to release the button again before another hotkey action would trigger (so, if someone sits on the keyboard it would not cause continuous hotkey events). However, I can't find where to catch WM_KEYUP events, so I can set a flag if it should process ProcessCmdKey messages again? Anyone can help out here? Thanks, Tom
