  • NHibernate Transactions Best Practices

    - by Ramiro
    I have been reading about Nhibernate for a while and have been trying to use it for a site I'm implementing. I read the article by Billy McCafferty on NHibernate best practices but I did not see any indication on where is the best place to handle transactions. I thought of putting that code in the Data Access Object (DAO) but then I'm not sure how to handle cases in which more than one DAO is used. What are the best places to put transaction code in your NHibernate Application?

  • Doctrine toarray does not convert relations.

    - by terrani
    Hi, so..I followed doctrine documnetation to get started. Here is the documentation http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:retrieving-related-records My code is $User = Doctrine_Core::getTable("User")->find(1); when I access relations by $User-Phonenumbers, it works. When I convert User object to array by using toArray() method, it does not convert relations to array. It simply display $User data. Am i missing something?

  • Django model: Reference foreign key table in __unicode__ function for admin

    - by pa
    Example models: class Parent(models.Model): name = models.CharField() def __unicode__(self): return self.name class Child(models.Model): parent = models.ForeignKey(Parent) def __unicode__(self): return self.parent.name # Would reference name above I'm wanting the Child.unicode to refer to Parent.name, mostly for the admin section so I don't end up with "Child object" or similar, I'd prefer to display it more like "Child of ". Is this possible? Most of what I've tried hasn't worked unfortunately.

    - by OscarTheGrouch
    I have an application where I would like to exchange information, managed via Core Data, between two iPhones. First turning the Core Data object to an NSDictionary (something very simple that gets turned into NSData to be transferred). My CoreData has 3 string attributes, 2 image attributes that are transformables. I have looked through the NSDictionary API but have not had any luck with it, creating or adding the CoreData information to it. Any help or sample code regarding this would be greatly appreciated.

  • Decent simple SQL Server client

    - by John
    Hi, does anyone know of a very simple SQL Server client tool - that does the same basic functions as Management Studio (i.e. choose a database and run a query - doesn't need an Object Explorer, or anything fancy)? Ideally it would be great to have a single exe or zip file version that I could take around on a USB key - anything to avoid installing the full set of SQL Server client tools all the time! Thanks, John

  • iFrame in Firefox hidden window with a contentWindow.history?

    - by Jon
    I'm trying to run a hosted script with content privileges in my Firefox extension. To do this, I create a content iframe in the hidden window pointed at a html file that pulls the script. This script requires the 'history' be available, but the iframes created in the hidden window have no history for some reason. Chromebug reports this for the iframe's contentWindow.history: object does not support history (nsIDOMHistory) And the script gives this error when its not available: Error: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHistory.length] Any ideas?

  • Sockets server design advice

    - by Rob
    We are writing a socket server in c# and need some advice on the design. Background: Clients (from mobile devices) connect to our server app and we leave their socket open so we can send data back down to them whenever we need to. The amount of data varies but we generally send/receive data from each client every few seconds, so it's quite intensive. The amount of simultaneous connections can range from 50-500 (and more in the future). We have already written a server app using async sockets and it works, however we've come across some stumbling blocks and we need to make sure that what we're doing is correct. We have a collection which holds our client states (we have no socket/connection pool at the moment, should we?). Each time a client connects we create a socket and then wait for them to send us some data and in receiveCallBack we add their clientstate object to our connections dictionary (once we have verified who they are). When a client object then signs off we shutdown their socket and then close it as well as remove them from our collection of clients dictionary. Presumably everything happens in the right order, everything works as expected. However, almost everyday it stops accepting connections, or so we think, either that or it connects but doesn't actually do anything past that and we can't work out why it's just stopping. There are few things that we'r'e unsure about 1) Should we be creating some kind of connection pool as opposed to just a dictionary of client sockets 2) What happens to the sockets that connect but then don't get added to our dictionary, they just linger around in memory doing nothing, should we create ANOTHER dictionary that holds the sockets as soon as they are created? 3) What's the best way of finding if clients are no longer connected? We've read some many methods but we're not sure of the best one to use, send data or read data, if so how? 4) If we loop through the connections dictonary to check for disposed clients, should we be locking the dictionary, if so how does this affect other clients objects trying to use it at the same time, will it throw an error or just wait? 5) We often get disposedSocketException within ReceiveCallBack method at random times, does this mean we are safe to remove that socket from the collection? We can't seem to find any production type examples which show any of this working. Any advice would be greatly received

  • Where can I find an iPhone OpenGL ES Example that responds to touch?

    - by Jamey McElveen
    I would like to find an iPhone OpenGL ES Example that responds to touch. Ideally it would meet these requirements: Displays a 3D object in the center of the screen like a cube Maps a texture to the cube surfaces Should move the camera around the cube as you drag your finger Should zoom the camera in and out on the cube by pinching Optionally has a background behind the cube that wraps around the back of the camera.(for example this could create the effect of the cube being in space) Has anyone seen one or more examples that can do these or at least render the cube with the texture?

  • WPF Using commands to slow to update UI controls

    - by toni
    Hi, I bind a command to a button through command property and doing a command binding in the page it is placed. In execute method I create an instance of a class that contains the background worker and I start it (this is a long task). The background worker (bw) class contains a variable isRunning that it is set to true before DoWork method is executed and to false when RunWorkerCompleted is executed. So from the code behind of the page where button is placed, in CanExecute method I set e.canExecute to true if bw is no running (isRunning = false), and e.canExecute to false if isRunning = true. WHen I press the button, it launch bw process for a long time and the button gets disabled. Ok this is correct, but when background worker (bw) finishes, the button doesn't returns to enabled until I press it again. When it is disabled and I press (when bw is finished) it gets enabled. Why the button is not returning automatically to enabled at the end of the bw? my code snippet: <Page x:Class="GParts.Pages.MyPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes; assembly=PresentationFramework.Aero" xmlns:local="clr-namespace:GParts" Loaded="Page_Loaded" Unloaded="Page_Unloaded" Height="Auto"> <Page.CommandBindings> <CommandBinding Command="{x:Static local:Pages.MyPage.rcmd}" Executed="CommandBinding_Executed" CanExecute="CommandBinding_CanExecute"/> </Page.CommandBindings> <...> <Button Command="{x:Static local:Pages.MyPage.rcmd}" /> <...> </Page> The code behind of the page: namespace GParts.Pages { public partial class MyPage : Page { public static RoutedCommand rcmd = new RoutedCommand(); private cBgWorker bw; <...> // ExecutedRoutedEventHandler for the custom button remove all command. private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e) { // get an isntance of the background worker class bw = new cBgWorker(); // start the long task bw.StartTask(); } // CanExecuteRoutedEventHandler for the custom button remove all command. private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e) { // bw is the instance of background worker class if (bw == null) { e.CanExecute = true; } else { e.CanExecute = !bw.isRunning;// isRunning indicates if bw is //executing now } } <...> } // end class } // end namespace

As Moose does automatic object building, i do not get to understand if this something possible, and how to create a Moose class with Moose syntax and having this behaviour Eg: The user asks: $file = Repository-new(uri='sftp://blabla') .... and is returned an Repository::_Sftp instance User would use $file as if it is a Repository instance, without the need to know the real subclass (polymorphism)
