  • What are the benefits of using ORM over XML Serialization/Deserialization?

    - by Tequila Jinx
    I've been reading about NHibernate and Microsoft's Entity Framework to perform Object Relational Mapping against my data access layer. I'm interested in the benefits of having an established framework to perform ORM, but I'm curious as to the performance costs of using it against standard XML Serialization and Deserialization. Right now, I develop stored procedures in Oracle and SQL Server that use XML Types for either input or output parameters and return or shred XML depending on need. I use a custom database command object that uses generics to deserialize the XML results into a specified serializable class. By using a combination of generics, xml (de)serialization and Microsoft's DAAB, I've got a process that's fairly simple to develop against regardless of the data source. Moreover, since I exclusively use Stored Procedures to perform database operations, I'm mostly protected from changes in the data structure. Here's an over-simplified example of what I've been doing. static void main() { testXmlClass test = new test(1); test.Name = "Foo"; test.Save(); } // Example Serializable Class ------------------------------------------------ [XmlRootAttribute("test")] class testXmlClass() { [XmlElement(Name="id")] public int ID {set; get;} [XmlElement(Name="name")] public string Name {set; get;} //create an instance of the class loaded with data. public testXmlClass(int id) { GenericDBProvider db = new GenericDBProvider(); this = db.ExecuteSerializable("myGetByIDProcedure"); } //save the class to the database... public Save() { GenericDBProvider db = new GenericDBProvider(); db.AddInParameter("myInputParameter", DbType.XML, this); db.ExecuteSerializableNonQuery("mySaveProcedure"); } } // Database Handler ---------------------------------------------------------- class GenericDBProvider { public T ExecuteSerializable<T>(string commandText) where T : class { XmlSerializer xml = new XmlSerializer(typeof(T)); // connection and command code is assumed for the purposes of this example. // the final results basically just come down to... return xml.Deserialize(commandResults) as T; } public void ExecuteSerializableNonQuery(string commandText) { // once again, connection and command code is assumed... // basically, just execute the command along with the specified // parameters which have been serialized. } public void AddInParameter(string name, DbType type, object value) { StringWriter w = new StringWriter(); XmlSerializer x = new XmlSerializer(value.GetType()); //handle serialization for serializable classes. if (type == DbType.Xml && (value.GetType() != typeof(System.String))) { x.Serialize(w, value); w.Close(); // store serialized object in a DbParameterCollection accessible // to my other methods. } else { //handle all other parameter types } } } I'm starting a new project which will rely heavily on database operations. I'm very curious to know whether my current practices will be sustainable in a high-traffic situation and whether or not I should consider switching to NHibernate or Microsoft's Entity Framework to perform what essentially seems to boil down to the same thing I'm currently doing. I appreciate any advice you may have.

  • Method interception in PHP 5.*

    - by Rolf
    Hi everybody, I'm implementing a Log system for PHP, and I'm a bit stuck. All the configuration is defined in an XML file, that declares every method to be logged. XML is well parsed and converted into a multidimensionnal array (classname = array of methods). So far, so good. Let's take a simple example: #A.php class A { public function foo($bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #B.php class B { public function far($boo) { echo $boo; } } Now, let's say I've this configuration file: <interceptor> <methods class="__CLASS_DIR__A.php"> <method name="foo"> <log-level>INFO</log-level> <log-message>Transaction init</log-message> </method> </methods> <methods class="__CLASS_DIR__B.php"> <method name="far"> <log-level>DEBUG</log-level> <log-message>Useless</log-message> </method> </methods> </interceptor> The thing I'd like AT RUNTIME ONLY (once the XML parser has done his job) is: #Logger.php (its definitely NOT a final version) -- generated by the XML parser class Logger { public function __call($name,$args) { $log_level = args[0]; $args = array_slice($args,1); switch($method_name) { case 'foo': case 'far': //case ..... //write in log files break; } //THEN, RELAY THE CALL TO THE INITIAL METHOD } } #"dynamic" A.php class A extends Logger { public function foo($log_level, $bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #"dynamic" B.php class B extends Logger { public function far($log_level, $boo) { echo $boo; } } The big challenge here is to transform A and B into their "dynamic" versions, once the XML parser has completed its job. The ideal would be to achieve that without modifying the code of A and B at all (I mean, in the files) - or at least find a way to come back to their original versions once the program is finished. To be clear, I wanna find the most proper way to intercept method calls in PHP. What are your ideas about it ??? Thanks in advance, Rolf

  • How to order a HasMany collection by a child property with Fluent NHibernate mapping

    - by Geoff Hardy
    I am using Fluent NHibernate to map the following classes: public abstract class DomainObject { public virtual int Id { get; protected internal set; } } public class Attribute { public virtual string Name { get; set; } } public class AttributeRule { public virtual Attribute Attribute { get; set; } public virtual Station Station { get; set; } public virtual RuleTypeId RuleTypeId { get; set; } } public class Station : DomainObject { public virtual IList<AttributeRule> AttributeRules { get; set; } public Station() { AttributeRules = new List<AttributeRule>(); } } My Fluent NHibernate mappings look like this: public class AttributeMap : ClassMap<Attribute> { public AttributeMap() { Id(o => o.Id); Map(o => o.Name); } } public class AttributeRuleMap : ClassMap<AttributeRule> { public AttributeRuleMap() { Id(o => o.Id); Map(o => o.RuleTypeId); References(o => o.Attribute).Fetch.Join(); References(o => o.Station); } } public class StationMap : ClassMap<Station> { public StationMap() { Id(o => o.Id); HasMany(o => o.AttributeRules).Inverse(); } } I would like to order the AttributeRules list on Station by the Attribute.Name property, but doing the following does not work: HasMany(o => o.AttributeRules).Inverse().OrderBy("Attribute.Name"); I have not found a way to do this yet in the mappings. I could create a IQuery or ICriteria to do this for me, but ideally I would just like to have the AttributeRules list sorted when I ask for it. Any advice on how to do this mapping?

  • Cutom event dispatchment location

    - by Martino Wullems
    Hello, I've been looking into custom event (listeners) for quite some time, but never succeeded in making one. There are so many different mehods, extending the Event class, but also Extending the EventDispatcher class, very confusing! I want to settle with this once and for all and learn the appriopate technique. package{ import flash.events.Event; public class CustomEvent extends Event{ public static const TEST:String = 'test'; //what exac is the purpose of the value in the string? public var data:Object; public function CustomEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, data:Object = null):void { this.data = data; super(); } } } As far as I know a custom class where you set the requirements for the event to be dispatched has to be made: package { import flash.display.MovieClip; public class TestClass extends MovieClip { public function TestClass():void { if (ConditionForHoldToComplete == true) { dispatchEvent(new Event(CustomEvent.TEST)); } } } } I'm not sure if this is correct, but it should be something along the lines of this. Now What I want is something like a mouseevent, which can be applied to a target and does not require a specific class. It would have to work something like this: package com.op_pad._events{ import flash.events.MouseEvent; import flash.utils.Timer; import flash.events.TimerEvent; import flash.events.EventDispatcher; import flash.events.Event; public class HoldEvent extends Event { public static const HOLD_COMPLETE:String = "hold completed"; var timer:Timer; public function SpriteEvent(type:String, bubbles:Boolean=true, cancelable:Boolean=false) { super( type, bubbles, cancelable ); timer = new Timer(1000, 1); //somehow find the target where is event is placed upon -> target.addEventlistener target.addEventListener(MouseEvent.MOUSE_DOWN, startTimer); target.addEventListener(MouseEvent.MOUSE_UP, stopTimer); } public override function clone():Event { return new SpriteEvent(type, bubbles, cancelable); } public override function toString():String { return formatToString("MovieEvent", "type", "bubbles", "cancelable", "eventPhase"); } ////////////////////////////////// ///// c o n d i t i o n s ///// ////////////////////////////////// private function startTimer(e:MouseEvent):void { timer.start(); timer.addEventListener(TimerEvent.TIMER_COMPLETE, complete); } private function stopTimer(e:MouseEvent):void { timer.stop() } public function complete(e:TimerEvent):void { dispatchEvent(new HoldEvent(HoldEvent.HOLD_COMPLETE)); } } } This obviously won't work, but should give you an idea of what I want to achieve. This should be possible because mouseevent can be applied to about everything.The main problem is that I don't know where I should set the requirements for the event to be executed to be able to apply it to movieclips and sprites. Thanks in advance

  • jQuery: Sort div's according to content of different sub divs

    - by rayne
    I'm trying to create a somewhat complex sorting feature which neither uses divs nor lists. Unfortunately two hours of googling didn't help me. Here is the basic setup of my HTML: <div id="all_elements"> <!-- one element --> <div class="element"> <div class="wrapper"> <a href="/" title="links"> <img src="/img/image.jpg" border="0" alt="image" class="image" /></a> <div class="details"> <h3><a href="/" title="title">Name (Sort Argument 1)</a></h3> <div class="title"><a href="/" title="title">Title (Sort Argument 2)</a></div> <div class="year">2010 (Sort Argumentt 3)</div> <div class="country">Great Britain (Sort Argument 4)</div> </div><!-- details --> </div><!-- wrapper --> </div><!-- element --> </div> <!--all_elements--> The setup is a bit complex, but basically .element is the element that needs to be sorted alphabetically according to either the contents of h3, div.title, div.year or div.country. So the user will be able to view the contents of the site either sorted by name, by year, by country or by title. I have this jQuery snippet from a website, but all my attempts on trying to tell it to use the contents of e.g. h3 to sort have failed. Right now it sorts pretty much randomly. jQuery.fn.sort = function() { return this.pushStack([].sort.apply(this, arguments), []); }; function sortAscending(a, b) { return a.innerHTML > b.innerHTML ? 1 : -1; }; function sortDescending(a, b) { return a.innerHTML < b.innerHTML ? 1 : -1; }; $(document).ready(function() { $("#sort").toggle( function() { $('#all_elements .element').sort(sortDescending).appendTo('#all_elements'); $(this).text("Sort Asc"); }, function() { $('#all_elements .element').sort(sortAscending).appendTo('#all_elements'); $(this).text("Sort Desc"); }); }); How can I customize the function to sort the contents of my h3 or divs?

  • How can I structure my MustacheJS template to add dynamic classes based on the values from a JSON file?

    - by JGallardo
    OBJECTIVE To build an app that allows the user to search for locations. CURRENT STATE At the moment the locations listed are few, so they are just all presented when landing on the "dealers" page. BACKGROUND Previously there were only about 50 showrooms carrying a product we sell, so a static HTML page was fine. And displays as But the page size grew to about 1500 lines of code after doing this. We have gotten more and need a scalable solution so that we can add many more dealers fast. In other projects, I have previously used MustacheJS and to load in values from a JSON file. I know the ideally this will be an AJAX application. Perhaps I might be better off with database here? Below is what I have in mind so far, and it "works" up to a certain point, but seems not to be anywhere near the most sustainable solution that can be efficiently scaled. HTML <a id="{{state}}"></a> <div> <h4>{{dealer}} : {{city}}, {{state}} {{l_type}}</h4> <div class="{{icon_class}}"> <ul> <li><i class="icon-map-marker"></i></li> <li><i class="icon-phone"></i></li> <li><i class="icon-print"></i></li> </ul> </div> <div class="listingInfo"> <p>{{street}} <br>{{suite}}<br> {{city}}, {{state}} {{zip}}<br> Phone: {{phone}}<br> {{toll_free}}<br> {{fax}} </p> </div> </div> <hr> JSON { "dealers" : [ { "dealer":"Benco Dental", "City":"Denver", "state":"CO", "zip":"80112", "l_type":"Showroom", "icon_class":"listingIcons_3la", "phone":"(303) 790-1421", "toll_free":null, "fax":"(303) 790-1421" }, { "dealer":"Burkhardt Dental Supply", "City":"Portland", "state":"OR", "zip":"97220", "l_type":"Showroom", "icon_class":"listingIcons", "phone":" (503) 252-9777", "toll_free":"(800) 367-3030", "fax":"(866) 408-3488" } ]} CHALLENGES The CSS class wrapping the ul will vary based on how many fields there are. In this case there are 3, so the class is "listingIcons_3la" The "toll free" number section should only show up if in fact, there is a toll free number. the fax number should only show up if there is a value for a fax number.

  • jQuery selectors - parental problems

    - by aressidi
    Hi there, I have an emote selector that opens up when a user clicks an entry in a diary. The way I've worked it is that the emote selector panel lives hidden at the top of the page. When a user clicks on the 'emote control' associated with an entry, I use JavaScript to grab the HTML of the emote selector panel from the top of the page and insert it next to the entry. Using Firebug, here's what the finished product would look like in the page (snippet from element inspect). I'm trying to get the ID for the class 'emote-control-container' which contains the entry id: <td> <div id="1467002" class="emote-select emote-default">&nbsp;</div> <div class="emote-control-container" id="emote-controls-1467002"> <div id="emote-control-selector"> <div id="emote-control-selector-body"> <ul> <li id="emote-1"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-2"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-3"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-4"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> </ul> </div> <div id="emote-control-selector-footer"> &nbsp; </div> </div> </div> </td> I need the entry ID along with the emote ID to make a post via AJAX when a user selects an emote from the selector panel by clicking on it. I'm able to get the emote ID just fine with this, which I'm using to alert-out the selected emote ID: jQuery('li').live('click', function(e) { e.preventDefault; var emoteId = this.id; alert(emoteId); }); I'm having trouble traversing up DOM to get the element ID from '.emote-control-container. I've tried everything, but I'd expect this to work, but it doesn't: jQuery('li').live('click', function(e) { e.preventDefault; var entryId = jQuery(this.id).parent(".emote-control-container").attr("id"); alert(entryId); }); What am I doing wrong.? I can't target the ID of the .emote-control-container.

  • Python4Delphi: Returning a python object in a function. (DelphiWrapper)

    - by Gabriel Fonseca
    I am using python4delphi. ow can I return an object from a wrapped Delphi class function? Code Snippet: I have a simple Delphi Class that i wrapped to Python Script, right? TSimple = Class Private function getvar1:string; Public Published property var1:string read getVar1; function getObj:TSimple; end; ... function TSimple.getVar1:string; begin result:='hello'; end; function TSimple.getObj:TSimple; begin result:=self; end; I made the TPySimple like the demo32 to give class access to the python code. My python module name is test. TPyDado = class(TPyDelphiPersistent) // Constructors & Destructors constructor Create( APythonType : TPythonType ); override; constructor CreateWith( PythonType : TPythonType; args : PPyObject ); override; // Basic services function Repr : PPyObject; override; class function DelphiObjectClass : TClass; override; end; ... { TPyDado } constructor TPyDado.Create(APythonType: TPythonType); begin inherited; // we need to set DelphiObject property DelphiObject := TDado.Create; with TDado(DelphiObject) do begin end; Owned := True; // We own the objects we create end; constructor TPyDado.CreateWith(PythonType: TPythonType; args: PPyObject); begin inherited; with GetPythonEngine, DelphiObject as TDado do begin if PyArg_ParseTuple( args, ':CreateDado' ) = 0 then Exit; end; end; class function TPyDado.DelphiObjectClass: TClass; begin Result := TDado; end; function TPyDado.Repr: PPyObject; begin with GetPythonEngine, DelphiObject as TDado do Result := VariantAsPyObject(Format('',[])); // or Result := PyString_FromString( PAnsiChar(Format('(%d, %d)',[x, y])) ); end; And now the python code: import test a = test.Simple() # try access the property var1 and everything is right print a.var1 # work's, but.. b = a.getObj(); # raise a exception that not find any attributes named getObj. # if the function returns a string for example, it's work.

  • Hibernate mapping to object that already exists

    - by teehoo
    I have two classes, ServiceType and ServiceRequest. Every ServiceRequest must specify what kind of ServiceType it is. All ServiceType's are predefined in the database, and ServiceRequest is created at runtime by the client. Here are my .hbm files: <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceRequest" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="quantity"> <column name="quantity" not-null="true"/> </property> <many-to-one cascade="all" class="xxx.model.entity.ServiceType" column="service_type" name="serviceType" not-null="false" unique="false"/> </class> </hibernate-mapping> and <hibernate-mapping> <class dynamic-insert="false" dynamic-update="false" mutable="true" name="xxx.model.entity.ServiceType" optimistic-lock="version" polymorphism="implicit" select-before-update="false"> <id column="USER_ID" name="id"> <generator class="native"/> </id> <property name="description"> <column name="description" not-null="false"/> </property> <property name="cost"> <column name="cost" not-null="true"/> </property> <property name="enabled"> <column name="enabled" not-null="true"/> </property> </class> </hibernate-mapping> When I run this, I get com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails I think my problem is that when I create a new ServiceRequest object, ServiceType is one of its properties, and therefore when I'm saving ServiceRequest to the database, Hibernate attempts to insert the ServiceType object once again, and finds that it is already exists. If this is the case, how do I make it so that Hibernate points to the exists ServiceType instead of trying to insert it again?

  • Java "compare cannot be resolved to a type" error

    - by King Triumph
    I'm getting a strange error when attempting to use a comparator with a binary search on an array. The error states that "compareArtist cannot be resolved to a type" and is thrown by Eclipse on this code: Comparator<Song> compare = new Song.compareArtist(); I've done some searching and found references to a possible bug with Eclipse, although I have tried the code on a different computer and the error persists. I've also found similar issues regarding the capitalization of the compare method, in this case compareArtist. I've seen examples where the first word in the method name is capitalized, although it was my understanding that method names are traditionally started with a lower case letter. I have experimented with changing the capitalization but nothing has changed. I have also found references to this error if the class doesn't import the correct package. I have imported java.util in both classes in question, which to my knowledge allows the use of the Comparator. I've experimented with writing the compareArtist method within the class that has the binary search call as well as in the "Song" class, which according to my homework assignment is where it should be. I've changed the constructor accordingly and the issue persists. Lastly, I've attempted to override the Comparator compare method by implementing Comparator in the Song class and creating my own method called "compare". This returns the same error. I've only moved to calling the comparator method something different than "compare" after finding several examples that do the same. Here is the relevant code for the class that calls the binary search that uses the comparator. This code also has a local version of the compareArtist method. While it is not being called currently, the code for this method is the same as the in the class Song, where I am trying to call it from. Thanks for any advice and insight. import java.io.*; import java.util.*; public class SearchByArtistPrefix { private Song[] songs; // keep a direct reference to the song array private Song[] searchResults; // holds the results of the search private ArrayList<Song> searchList = new ArrayList<Song>(); // hold results of search while being populated. Converted to searchResults array. public SearchByArtistPrefix(SongCollection sc) { songs = sc.getAllSongs(); } public int compareArtist (Song firstSong, Song secondSong) { return firstSong.getArtist().compareTo(secondSong.getArtist()); } public Song[] search(String artistPrefix) { String artistInput = artistPrefix; int searchLength = artistInput.length(); Song searchSong = new Song(artistInput, "", ""); Comparator<Song> compare = new Song.compareArtist(); int search = Arrays.binarySearch(songs, searchSong, compare);

  • Can I use VS2010's Intellitrace to gather data for a Windows Service?

    - by rwmnau
    I have a Windows service that I'd like to gather some debugging data on using Intellitrace - the problem is that you can't debug a Windows Service by starting it directly from inside VS. I have the service installed, and the very first statement in Service.Start is "Debug.Break", which allows me to attach VS. However, you can't use Intellitrace if a process is already started when you attach. Does anybody know of a workaround for this?

  • How can I debug a Windows service that crashes?

    - by Christopher
    I have a .NET Windows service that appears to be crashing due to C00000005 (access violation--according to Dr Watson). When I attach the VS debugger to it--whether I build it with or without symbols--the VS debugger just stops when the service crashes, instead of stopping to give me a chance to do any investigation. Is that to be expected, or am I doing something wrong? Will using WinDbg let me do something more in real time (obviously, WinDbg lets me do crash dump analysis)? Thanks!

  • How to pull/push data from/to existing SAP system?

    - by Ahmed
    I need to connect to a SAP system, to pull/push data to/from that system? I downloaded SAP PDK for .NET, build a solution using it, but this requires Portal Runtime for .NET to be installed on server, and this cannot be done, because SAP server is a Solaris one! Also, I've checked existing solutions, but all of them use VS.NET 2003, to create what is called SAP Connector Proxy? So, is there a way to connect to SAP system apart from using VS.NET 2003?

  • How do I apply a servlet filter when serving an HTML page directly?

    - by Philippe Beaudoin
    First off, I'm using Google AppEngine and Guice, but I suspect my problem is not related to these. When the user connect to my (GWT) webapp, the URL is a direct html page. For example, in development mode, it is: http://127.0.0.1:8888/Puzzlebazar.html?gwt.codesvr=127.0.0.1:9997. Now, I setup my web.xml in the following way: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>PuzzleBazar</display-name> <!-- Default page to serve --> <welcome-file-list> <welcome-file>Puzzlebazar.html</welcome-file> </welcome-file-list> <filter> <filter-name>guiceFilter</filter-name> <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> </filter> <filter-mapping> <filter-name>guiceFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- This Guice listener hijacks all further filters and servlets. Extra filters and servlets have to be configured in your ServletModule#configureServlets() by calling serve(String).with(Class<? extends HttpServlet>) and filter(String).through(Class<? extends Filter) --> <listener> <listener-class>com.puzzlebazar.server.guice.MyGuiceServletContextListener </listener-class> </listener> </web-app> Since I'm using Guice, I have to configure extra filters in my ServletModule, where I do this: filter("*.html").through( SecurityCookieFilter.class ); But my SecurityCookieFilter.doFilter is never called. I tried things like "*.html*" or <url-pattern>*</url-pattern> but to no avail. Any idea how I should do this?

  • How do I change a child's parent in NHibernate when cascade is delete-all-orphan?

    - by Daniel T.
    I have two entities in a bi-directional one-to-many relationship: public class Storage { public IList<Box> Boxes { get; set; } } public class Box { public Storage CurrentStorage { get; set; } } And the mapping: <class name="Storage"> <bag name="Boxes" cascade="all-delete-orphan" inverse="true"> <key column="Storage_Id" /> <one-to-many class="Box" /> </bag> </class> <class name="Box"> <many-to-one name="CurrentStorage" column="Storage_Id" /> </class> A Storage can have many Boxes, but a Box can only belong to one Storage. I have them mapped so that the one-to-many has a cascade of all-delete-orphan. My problem arises when I try to change a Box's Storage. Assuming I already ran this code: var storage1 = new Storage(); var storage2 = new Storage(); storage1.Boxes.Add(new Box()); Session.Create(storage1); Session.Create(storage2); The following code will give me an exception: // get the first and only box in the DB var existingBox = Database.GetBox().First(); // remove the box from storage1 existingBox.CurrentStorage.Boxes.Remove(existingBox); // add the box to storage2 after it's been removed from storage1 var storage2 = Database.GetStorage().Second(); storage2.Boxes.Add(existingBox); Session.Flush(); // commit changes to DB I get the following exception: NHibernate.ObjectDeletedException : deleted object would be re-saved by cascade (remove deleted object from associations) This exception occurs because I have the cascade set to all-delete-orphan. The first Storage detected that I removed the Box from its collection and marks it for deletion. However, when I added it to the second Storage (in the same session), it attempts to save the box again and the ObjectDeletedException is thrown. My question is, how do I get the Box to change its parent Storage without encountering this exception? I know one possible solution is to change the cascade to just all, but then I lose the ability to have NHibernate automatically delete a Box by simply removing it from a Storage and not re-associating it with another one. Or is this the only way to do it and I have to manually call Session.Delete on the box in order to remove it?

  • How do I set Environment Variables in Visual Studio 2010?

    - by xarzu
    How do I set Environment Variables in Visual Studio 2010? I found this web page: http://msdn.microsoft.com/en-us/library/ee479070.aspx Which says: From the Project menu, choose Properties. In the left pane, select Configuration Properties, and then select Environment. But when I select "Configuration Properties", there is no "Enviroment" option: http://i67.photobucket.com/albums/h292/Athono/microsoft/newstuff.jpg This is an example in VS 2008: http://i21.photobucket.com/albums/b279/GrunchCan/env.jpg But how is it done in VS 2010?

  • .net VS2008 compilation analyzer tool ?

    - by Matthieu
    Hi, I'm looking for a tool that allows me to analyze the compilation of a VS Solution (about 30 VS projects inside). I would like to know after the global solution compilation, which projets fail and forward errors to developers. Of course, I could analyze the compilation report... but I'm pretty sure that great tools are available ! What is for you the best one ? Thanks a lot !

  • WordPress: Using custom field to define posts to display in loop

    - by j-man86
    Hi, I'm trying to use a custom field in which I input the post ID numbers of the posts I want to show, seperated by commas. For some reason though, only the first post of the series of the post IDs are displaying. Can someone help? The value of $nlPostIds is (minus the quotes): "1542,1534,1546". Here's the code... the most important part is the 4th line 'post__in' => array($nlPostIds) <?php $nlPostIds = get_post_meta($post->ID, 'nlPostIds', true); $args=array( 'post__in' => array($nlPostIds) ); query_posts($args); if ( $wp_query->have_posts() ) : while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?> <div class="entry"> <div class="post" id="post-<?php the_ID(); ?>"> <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2> <div class="allinfos"><span class="date"><?php the_time('F jS, Y') ?></span> | <span class="comments"><?php comments_popup_link('No Comments', '1 Comment', '% Comments'); ?> </span> | <span class="category">Posted in <?php the_category(', ') ?></span> <!-- by <?php the_author() ?> --></div> <?php the_content('More &raquo;'); ?> <?php the_tags('Tags: ', ', ', ' '); ?> <?php edit_post_link('Edit', '[ ', ' ]'); ?> <div class="clear"></div> </div></div> <?php endwhile; endif; ?> Thanks!
