• NHibernate Proxy Creation

  - by Chris Meek

  I have a class structure like the following class Container { public virtual int Id { get; set; } public IList<Base> Bases { get; set; } } class Base { public virtual int Id { get; set; } public virtual string Name { get; set; } } class EnemyBase : Base { public virtual int EstimatedSize { get; set; } } class FriendlyBase : Base { public virtual int ActualSize { get; set; } } Now when I ask the session for a particular Container it normally gives me the concrete EnemyBase and FriendlyBase objects in the Bases collection. I can then (if I so choose) cast them to their concrete types and do something specific with them. However, sometime I get a proxy of the "Base" class which is not castable to the concrete types. The same method is used both times with the only exception being that in the case that I get proxies I have added some related entities to the session (think the friendly base having a collection of people or something like that). Is there any way I can prevent it from doing the proxy creating and why would it choose to do this in some scenarios? UPDATE The mappings are generated with the automap feature of fluentnhibernate but look something like this when exported <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" mutable="true" name="Base" table="`Base`"> <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="MyIdGenerator" /> </id> <property name="Name" type="String"> <column name="Name" /> </property> <joined-subclass name="EnemyBase"> <key> <column name="Id" /> </key> <property name="EstimatedSize" type="Int"> <column name="EstimatedSize" /> </property> </joined-subclass> <joined-subclass name="FriendlyBase"> <key> <column name="Id" /> </key> <property name="ActualSize" type="Int"> <column name="ActualSize" /> </property> </joined-subclass> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" mutable="true" name="Container" table="`Container`"> <id name="Id" type="System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="MyIdGenerator" /> </id> <bag cascade="all-delete-orphan" inverse="true" lazy="false" name="Bases" mutable="true"> <key> <column name="ContainerId" /> </key> <one-to-many class="Base" /> </bag> </class> </hibernate-mapping>

• Code Access Security and Sharepoint WebParts

  - by Gordon Carpenter-Thompson

  I've got a vague handle on how Code Access Security works in Sharepoint. I have developed a custom webpart and setup a CAS policy in my Manifest <CodeAccessSecurity> <PolicyItem> <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for Okana"> <IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" version="1" ObjectModel="True" Impersonate="True" /> <IPermission class="SecurityPermission" version="1" Flags="Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration" /> <IPermission class="AspNetHostingPermission" version="1" Level="Medium" /> <IPermission class="DnsPermission" version="1" Unrestricted="true" /> <IPermission class="EventLogPermission" version="1" Unrestricted="true"> <Machine name="localhost" access="Administer" /> </IPermission> <IPermission class="EnvironmentPermission" version="1" Unrestricted="true" /> <IPermission class="System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" version="1" Unrestricted="true"/> <IPermission class="System.Net.WebPermission, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Unrestricted="true" /> <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" PathDiscovery="*AllFiles*" /> <IPermission class="IsolatedStorageFilePermission" version="1" Allowed="AssemblyIsolationByUser" UserQuota="9223372036854775807" /> <IPermission class="PrintingPermission" version="1" Level="DefaultPrinting" /> <IPermission class="PerformanceCounterPermission" version="1"> <Machine name="localhost"> <Category name="Enterprise Library Caching Counters" access="Write"/> <Category name="Enterprise Library Cryptography Counters" access="Write"/> <Category name="Enterprise Library Data Counters" access="Write"/> <Category name="Enterprise Library Exception Handling Counters" access="Write"/> <Category name="Enterprise Library Logging Counters" access="Write"/> <Category name="Enterprise Library Security Counters" access="Write"/> </Machine> </IPermission> <IPermission class="ReflectionPermission" version="1" Unrestricted="true"/> <IPermission class="SecurityPermission" version="1" Flags="SerializationFormatter, UnmanagedCode, Infrastructure, Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration, ControlAppDomain,ControlDomainPolicy" /> <IPermission class="SharePointPermission" version="1" ObjectModel="True" /> <IPermission class="SmtpPermission" version="1" Access="Connect" /> <IPermission class="SqlClientPermission" version="1" Unrestricted="true"/> <IPermission class="WebPartPermission" version="1" Connections="True" /> <IPermission class="WebPermission" version="1"> <ConnectAccess> <URI uri="$OriginHost$"/> </ConnectAccess> </IPermission> </PermissionSet> <Assemblies> .... </Assemblies> This is correctly converted into a wss_custom_wss_minimaltrust.config when it is deployed onto the Sharepoint server and mostly works. To get the WebPart working fully, however I find that I need to modify the wss_custom_wss_minimaltrust.config by hand after deployment and set Unrestricted="true" on the permissions set <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1"> to <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1" Unrestricted="true"> It's all because I'm loading a User Control from the webpart. I don't believe there is a way to enable that using CAS but am willing to be proven wrong. Is there a way to set something in the manifest so I don't need to make this fix by hand? Thanks

• Ado.net Fill method not throwing error on running a Stored Procedure that does not exist.

  - by Mike

  I am using a combination of the Enterprise library and the original Fill method of ADO. This is because I need to open and close the command connection myself as I am capture the event Info Message Here is my code so far // Set Up Command SqlDatabase db = new SqlDatabase(ConfigurationManager.ConnectionStrings[ConnectionName].ConnectionString); SqlCommand command = db.GetStoredProcCommand(StoredProcName) as SqlCommand; command.Connection = db.CreateConnection() as SqlConnection; // Set Up Events for Logging command.StatementCompleted += new StatementCompletedEventHandler(command_StatementCompleted); command.Connection.FireInfoMessageEventOnUserErrors = true; command.Connection.InfoMessage += new SqlInfoMessageEventHandler(Connection_InfoMessage); // Add Parameters foreach (Parameter parameter in Parameters) { db.AddInParameter(command, parameter.Name, (System.Data.DbType)Enum.Parse(typeof(System.Data.DbType), parameter.Type), parameter.Value); } // Use the Old Style fill to keep the connection Open througout the population // and manage the Statement Complete and InfoMessage events SqlDataAdapter da = new SqlDataAdapter(command); DataSet ds = new DataSet(); // Open Connection command.Connection.Open(); // Populate da.Fill(ds); // Dispose of the adapter if (da != null) { da.Dispose(); } // If you do not explicitly close the connection here, it will leak! if (command.Connection.State == ConnectionState.Open) { command.Connection.Close(); } ... Now if I pass into the variable StoredProcName = "ThisProcDoesNotExists" And run this peice of code. The CreateCommand nor da.Fill through an error message. Why is this. The only way I can tell it did not run was that it returns a dataset with 0 tables in it. But when investigating the error it is not appearant that the procedure does not exist. EDIT Upon further investigation command.Connection.FireInfoMessageEventOnUserErrors = true; is causeing the error to be surpressed into the InfoMessage Event From BOL When you set FireInfoMessageEventOnUserErrors to true, errors that were previously treated as exceptions are now handled as InfoMessage events. All events fire immediately and are handled by the event handler. If is FireInfoMessageEventOnUserErrors is set to false, then InfoMessage events are handled at the end of the procedure. What I want is each print statement from Sql to create a new log record. Setting this property to false combines it as one big string. So if I leave the property set to true, now the question is can I discern a print message from an Error ANOTHER EDIT So now I have the code so that the flag is set to true and checking the error number in the method void Connection_InfoMessage(object sender, SqlInfoMessageEventArgs e) { // These are not really errors unless the Number >0 // if Number = 0 that is a print message foreach (SqlError sql in e.Errors) { if (sql.Number == 0) { Logger.WriteInfo("Sql Message",sql.Message); } else { // Whatever this was it was an error throw new DataException(String.Format("Message={0},Line={1},Number={2},State{3}", sql.Message, sql.LineNumber, sql.Number, sql.State)); } } } The issue now that when I throw the error it does not bubble up to the statement that made the call or even the error handler that is above that. It just bombs out on that line The populate looks like // Populate try { da.Fill(ds); } catch (Exception e) { throw new Exception(e.Message, e); } Now even though I see the calling codes and methods still in the Call Stack, this exception does not seem to bubble up?

• how to use ggplot conditional on data

  - by Andreas

  I asked this question and it seams ggplot2 currently has a bug with empty data.frames. Therefore I am trying to check if the dataframe is empty, before I make the plot.

alpha=0.5)+ This is kindda of important to me, and I am really stuck trying to find a solution. Any help that will get me started is much appreciated. Thanks in advance.

• Ladder-like word game in Java

  - by sasquatch90

  I've found this question http://stackoverflow.com/questions/2844190/choosing-design-method-for-ladder-like-word-game and I would also like to do this kind of program. I've written some code but already have two issues. Here's what I already have : GRID : public class Grid { public Grid(){} public Grid( Element e ){} } ELEMENT : public class Element { final int INVISIBLE = 0; final int EMPTY = 1; final int FIRST_LETTER = 2; final int OTHER_LETTER = 3; private int state; private String letter; public Element(){} //empty block public Element(int state){ this("", 0); } //filled block public Element(String s, int state){ this.state = state; this.letter = s; } public static void changeState(int s){ } public int getState(){ return state; } public boolean equalLength(){ return true; } public boolean equalValue(){ return true; } @Override public String toString(){ return "["+letter+"]"; } } MAIN: import java.util.Scanner; public class Main { public static void main(String[] args){ Scanner sc = new Scanner(System.in); System.out.println("Height: "); while (!sc.hasNextInt()) { System.out.println("int, please!"); sc.next(); } final int height = sc.nextInt(); Grid[] game = new Grid[height]; for(int i = 1; i <= height; i++) { String s; do { System.out.println("Length " + i + ", please!"); s = sc.next(); } while (s.length() != i); Element[] line = new Element[s.length()+1]; Element single = null; String[] temp = null; //issue here temp = s.split(""); System.out.println("s.length: "+s.length()); System.out.println("temp.length: "+temp.length); // for(String str : temp){ System.out.println("str:"+str); } for (int k = 0 ; k < temp.length ; k++) { if( k == 0 ){ single = new Element(temp[k], 2); System.out.println("single1: "+single); } else{ single = new Element(temp[k], 3); System.out.println("single2: "+single); } line[k] = single; } for (Element l : line) { System.out.println("line:"+l); } //issue here game[i] = line; } // for (Grid g : game) { System.out.println(g); } } } And sample output for debug : Height: 3 Length 1, please! A s.length: 1 temp.length: 2 str: str:A single1: [] single2: [A] line:[] line:[A] Here's what I think it should work like. I grab a word from user. Next create Grid element for whole game. Then for each line I create Element[] array called line. I split the given text and here's the first problem. Why string.split() adds a whitespace ? You can see clearly in output that it is added for no reason. How can I get rid of it (now I had to add +1 to the length of line just to run the code). Continuing I'm throwing the splitted text into temporary String array and next from each letter I create Element object and throw it to line array. Apart of this empty space output looks fine. But next problem is with Grid. I've created constructor taking Element as an argument, but still I can't throw line as Grid[] elements because of 'incompatible types'. How can I fix that ? Am I even doing it right ? Maybe I should get rid of line as Element[] and just create Grid[][] ?

• PHP hooks information and help needed

  - by sea_1987

  Background I am realtively new to hooks, and I have been asked to use a hook to populate a view with some data, currently the view gathers it data from a function that is in the model, and becuase the whole object is being passed to the view I can access the function. The function looks like this, public function numCVInSector($k) { $this->load->model('SYSector'); $sectorModel = new SYSector(); $cvs = $sectorModel->fetchRelatedCV($k); $cvs = $cvs[0]['count']; if($cvs == "0") { return false; } else { return $cvs; } } it call's a query in the model that looks like this, public function fetchRelatedCV($k) { $sql = "SELECT sector_id, COUNT(sector_id) as count FROM sy_user_sectors WHERE sector_id = $k"; //print_r($sql); $query = $this->db->query($sql); return $query->result_array(); } $k is the id of element that is in the view. The Problem I have been asked to use a hook that is in the parent of the model the hook is called post populate, now I have very little idea of what a hook is or how to use one to implement my function. Could some one give me some advice, the code where the hook is original made looks like this, public function populate($where = array()) { $results = array( "success" => false, "is_error" => false, "error_code" => "", "error_message" => "" ); if(empty($where) && empty($this->aliases['id'])){ $results['is_error'] = true; $results['error_message'] = 'No criteria.'; return $results; } // [hook] $this->prePopulate(); $where = count($where) > 0 ? $where : array('id' => $this->aliases['id']); $query = $this->db->get_where($this->tableName, $where, 1); if($query->num_rows() < 1){ $results['error_message'] = 'Empty results.'; return $results; } foreach($query->result_array() as $row){ foreach($this->aliases as $key => $val){ $this->aliases[$key] = $row[$key]; } } // [hook] $this->postPopulate(); // Presume success $results['success'] = true; return $results; } I have been asked to use the postPopulate hook. public function postPopulate() { $args = $this->getHookArgs('post_populate'); if(!is_array($args)){ // $this->fb->log($args, 'bad args'); return false; } // code here... // Convert dates to front end formats. foreach($this->frontEndDateFields as $fieldName => $dateFormat){ $dateRes = mlib_du_getFormattedMySQLDate($this->aliases[$fieldName], $dateFormat); if($dateRes != false){ $this->aliases[$fieldName] = $dateRes; } } return true; }

• FMOD surround sound openframeworks

  - by user1449425

  Ok, I hope I don't mess this up, I have had a look for some answers but can't find anything. I am trying to make a simple sampler in openframeworks using the FMOD sound player in 3D mode. I can make a single instance work fine (recording a new file using libsndfilerecorder and then playing it back and moving it in surround. However I want to have 8 layers of looping audio that I can record and replace one layer at a time in a live show. I get a lot of problems as soon as I have more than 1 layer. The first part of my question relates to the FMOD 3D modes, it is listener relative, so I have to define the position of my listener for every sound (I would prefer to have head relative mode but I cannot make this work at all. Again this works fine when I am using a single player but with multiple players only the last listener I update actually works. The main problem I have is that when I use multiple players I get distortion, and often a mix of other currently playing sounds (even when the microphone cannot hear them) in my new recordings. Is there an incompatability with libsndfilerecorder and FMOD? Here I initialise the players for (int i=0; i<CHANNEL_COUNT; i++) { lvelocity[i].set(1, 1, 1); lup[i].set(0, 1, 0); lforward[i].set(0, 0, 1); lposition[i].set(0, 0, 0); sposition[i].set(3, 3, 2); svelocity[i].set(1, 1, 1); //player[1].initializeFmod(); //player[i].loadSound( "1.wav" ); player[i].setVolume(0.75); player[i].setMultiPlay(true); player[i].play(); setupHold[i]==false; recording[i]=false; channelHasFile[i]=false; settingOsc[i]=false; } When I am recording I unload the file and make sure the positions of the player that is not loaded are not updating. void fmodApp::recordingStart( int recordingId ){ if (recording[recordingId]==false) { setupHold[recordingId]=true; //this stops the position updating cout<<"Start recording Channel " + ofToString(recordingId+1)+" setup hold is true \n"; pt=getDateName() +".wav"; player[recordingId].stop(); player[recordingId].unloadSound(); audioRecorder.setup(pt); audioRecorder.setFormat(SF_FORMAT_WAV | SF_FORMAT_PCM_16); recording[recordingId]=true; //this starts the libSndFIleRecorder } else { cout<<"Channel" + ofToString(recordingId+1)+" is already recording \n"; } } And I stop the recording like this. void fmodApp::recordingEnd( int recordingId ){ if (recording[recordingId]=true) { recording[recordingId]=false; cout<<"Stop recording" + ofToString(recordingId+1)+" \n"; audioRecorder.finalize(); audioRecorder.close(); player[recordingId].loadSound(pt); setupHold[recordingId]=false; channelHasFile[recordingId]=true; cout<< "File recorded channel " + ofToString(recordingId+1) + " file is called " + pt + "\n"; } else { cout << "Sorry track" + ofToString(recordingId+1) + "is not recording"; } } I am careful not to interrupt the updating process but I cannot see where I am going wrong. Many Thanks

• Fluent Nhibernate - how do i specify table schemas when auto generating tables in SQL CE 4

  - by daffers

  I am using SQL CE as a database for running local and CI integration tests (normally our site runs on normal SQL server). We are using Fluent Nhibernate for our mapping and having it create our schema from our Mapclasses. There are only two classes with a one to many relationship between them. In our real database we use a non dbo schema. The code would not work with this real database at first until i added schema names to the Table() methods. However doing this broke the unit tests with the error... System.Data.SqlServerCe.SqlCeException : There was an error parsing the query. [ Token line number = 1,Token line offset = 26,Token in error = User ] These are the classes and associatad MapClasses (simplified of course) public class AffiliateApplicationRecord { public virtual int Id { get; private set; } public virtual string CompanyName { get; set; } public virtual UserRecord KeyContact { get; private set; } public AffiliateApplicationRecord() { DateReceived = DateTime.Now; } public virtual void AddKeyContact(UserRecord keyContactUser) { keyContactUser.Affilates.Add(this); KeyContact = keyContactUser; } } public class AffiliateApplicationRecordMap : ClassMap<AffiliateApplicationRecord> { public AffiliateApplicationRecordMap() { Schema("myschema"); Table("Partner"); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.CompanyName, "Name"); References(x => x.KeyContact) .Cascade.All() .LazyLoad(Laziness.False) .Column("UserID"); } } public class UserRecord { public UserRecord() { Affilates = new List<AffiliateApplicationRecord>(); } public virtual int Id { get; private set; } public virtual string Forename { get; set; } public virtual IList<AffiliateApplicationRecord> Affilates { get; set; } } public class UserRecordMap : ClassMap<UserRecord> { public UserRecordMap() { Schema("myschema"); Table("[User]");//Square brackets required as user is a reserved word Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Forename); HasMany(x => x.Affilates); } } And here is the fluent configuraton i am using .... public static ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database( MsSqlCeConfiguration.Standard .Dialect<MsSqlCe40Dialect>() .ConnectionString(ConnectionString) .DefaultSchema("myschema")) .Mappings(m => m.FluentMappings.AddFromAssembly(typeof(AffiliateApplicationRecord).Assembly)) .ExposeConfiguration(config => new SchemaExport(config).Create(false, true)) .ExposeConfiguration(x => x.SetProperty("connection.release_mode", "on_close")) //This is included to deal with a SQLCE issue http://stackoverflow.com/questions/2361730/assertionfailure-null-identifier-fluentnh-sqlserverce .BuildSessionFactory(); } The documentation on this aspect of fluent is pretty weak so any help would be appreciated

• Strange problem with Google App Engine Java Mail

  - by Velu

  Hi, I'm using the MailService feature of Google App Engine in my application. It works fine in one application without any issues. But the same code doesn't work in another app. I'm not able to figure it out. Please help. Following is the piece of code that I use to send mail. public static void sendHTMLEmail(String from, String fromName, String to, String toName, String subject, String body) { _logger.info("entering ..."); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); _logger.info("got mail session ..."); String htmlBody = body; try { Message msg = new MimeMessage(session); _logger.info("created mimemessage ..."); msg.setFrom(new InternetAddress(from, fromName)); _logger.info("from is set ..."); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( to, toName)); _logger.info("recipient is set ..."); msg.setSubject(subject); _logger.info("subject is set ..."); Multipart mp = new MimeMultipart(); MimeBodyPart htmlPart = new MimeBodyPart(); htmlPart.setContent(htmlBody, "text/html"); mp.addBodyPart(htmlPart); _logger.info("body part added ..."); msg.setContent(mp); _logger.info("content is set ..."); Transport.send(msg); _logger.info("email sent successfully."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); System.err.println(e.getMessage()); } } When I look at the log (on the server admin console), it prints the statement "content is set ..." and after that there is nothing in the log. The mail is not sent. At times I get the following error after the above statement is printed (and the mail is not sent). com.google.appengine.repackaged.com.google.common.base.internal.Finalizer getInheritableThreadLocalsField: Couldn't access Thread.inheritableThreadLocals. Reference finalizer threads will inherit thread local values. But the mail quota usage keeps increasing. Remember, this works fine in one application, but not in other. I'm using the same set of email addresses in both the apps (for from and to). I'm really stuck with this. Appreciate any help. Thank you. Velu

• Trouble with Code First DatabaseGenerated Composite Primary Key

  - by Nick Fleetwood

  This is a tad complicated, and please, I know all the arguments against natural PK's, so we don't need to have that discussion. using VS2012/MVC4/C#/CodeFirst So, the PK is based on the date and a corresponding digit together. So, a few rows created today would be like this: 20131019 1 20131019 2 And one created tomorrow: 20131020 1 This has to be automatically generated using C# or as a trigger or whatever. The user wouldn't input this. I did come up with a solution, but I'm having problems with it, and I'm a little stuck, hence the question. So, I have a model: public class MainOne { //[Key] //public int ID { get; set; } [Key][Column(Order=1)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketDate { get; set; } [Key][Column(Order=2)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketNumber { get; set; } [StringLength(3, ErrorMessage = "Corp Code must be three letters")] public string CorpCode { get; set; } [StringLength(4, ErrorMessage = "Corp Code must be four letters")] public string DocketStatus { get; set; } } After I finish the model, I create a new controller and views using VS2012 scaffolding. Then, what I'm doing is debugging to create the database, then adding the following instead of trigger after Code First creates the DB [I don't know if this is correct procedure]: CREATE TRIGGER AutoIncrement_Trigger ON [dbo].[MainOnes] instead OF INSERT AS BEGIN DECLARE @number INT SELECT @number=COUNT(*) FROM [dbo].[MainOnes] WHERE [DocketDate] = CONVERT(DATE, GETDATE()) INSERT INTO [dbo].[MainOnes] (DocketDate,DocketNumber,CorpCode,DocketStatus) SELECT (CONVERT(DATE, GETDATE ())),(@number+1),inserted.CorpCode,inserted.DocketStatus FROM inserted END And when I try to create a record, this is the error I'm getting: The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: The object state cannot be changed. This exception may result from one or more of the primary key properties being set to null. Non-Added objects cannot have null primary key values. See inner exception for details. Now, what's interesting to me, is that after I stop debugging and I start again, everything is perfect. The trigger fired perfectly, so the composite PK is unique and perfect, and the data in other columns is intact. My guess is that EF is confused by the fact that there is seemingly no value for the PK until AFTER an insert command is given. Also, appearing to back this theory, is that when I try to edit on of the rows, in debug, I get the following error: The number of primary key values passed must match number of primary key values defined on the entity. Same error occurs if I try to pull the 'Details' or 'Delete' function. Any solution or ideas on how to pull this off? I'm pretty open to anything, even creating a hidden int PK. But it would seem redundant. EDIT 21OCT13 [HttpPost] public ActionResult Create(MainOne mainone) { if (ModelState.IsValid) { var countId = db.MainOnes.Count(d => d.DocketDate == mainone.DocketNumber); //assuming that the date field already has a value mainone.DocketNumber = countId + 1; //Cannot implicitly convert type int to string db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); } return View(mainone); } EDIT 21OCT2013 FINAL CODE SOLUTION For anyone like me, who is constantly searching for clear and complete solutions. if (ModelState.IsValid) { String udate = DateTime.UtcNow.ToString("yyyy-MM-dd"); mainone.DocketDate = udate; var ddate = db.MainOnes.Count(d => d.DocketDate == mainone.DocketDate); //assuming that the date field already has a value mainone.DocketNumber = ddate + 1; db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); }

• Edit of self referencing HABTM in cakephp works, sometimes

  - by Odegard

  I'm using a self referencing HABTM model with Participants. You sign up for an event and when you log in to your reservation/profile you see a list of other participants and you can choose to add yourself and others into various groups; share hotel room, share transportation from airport etc. What I've managed so far: 1) In my profile I see the list of all other participants with checkboxes. Great so far. 2) Adding another participant works fine. Next time I edit, the participant I added is shown as checked. 3) Removing another participant works fine too as long as you still have checked participants before you submit! Again, with words: There are 3 participants. I'm logged in as one of them, and I see the 2 other people on the participants list. I choose to check both of them. This works fine (always). Later I choose to remove one of them (by unchecking the checkbox and hitting submit). This also works fine (always). If I want to remove the last checkbox... nothing is updated (always!). What's curious is that I can add and remove any odd combination of participants and it will always work UNLESS I choose to remove every participants in one go (removing a one and only participant is a special case of "remove all checked participants"). As far as I know, HABTMs work by first deleting all relations, then re-saving them. I can see that in my tables when I remove, add, remove, add the same participant over and over again - the id on the HABTM table is always increasing. When I deselect all participants at once, however, the relations are not updated. The ids stay the same, so it's like the save never happened. This behaviour is so specific and peculiar, I have a feeling I'm missing something obvious here. Anyway, here's the relevant code: Model class Participant extends AppModel { var $hasAndBelongsToMany = array( 'buddy' = array( 'className' = 'Participant', 'joinTable' = 'participants_participants', 'foreignKey' = 'participant_id', 'associationForeignKey' = 'buddy_id', 'unique' = true, ) ); Controller function edit($id = null) { if (!$id && empty($this-data)) { $this-Session-setFlash(__('Invalid Participant', true)); $this-redirect(array('action'='index')); } if (!empty($this-data)) { if ($this-Participant-saveAll($this-data)) { $this-Session-setFlash(__('The Participant has been saved', true)); $this-redirect(array('action'='index')); } else { $this-Session-setFlash(__('The Participant could not be saved. Please, try again.', true)); } } if (empty($this-data)) { $this-data = $this-Participant-read(null, $id); } // Fetching all participants except yourself $allParticipants = $this-Participant-find('list', array('conditions' = array('participant.id ' = $id))); // Fetching every participant that has added you to their list $allBuddies = $this-Participant-ParticipantsParticipant-find('list', array( 'conditions' = array('buddy_id' = $id), 'fields' = 'ParticipantsParticipant.participant_id', 'order' = 'ParticipantsParticipant.participant_id ASC' )); $this-set(compact('allParticipants','allBuddies')); } View echo $form-create('Participant'); echo $associations-habtmCheckBoxes($allParticipants, $this-data['buddy'], 'buddy', 'div', '\'border: 1px solid #000;\'', '\'border: 1px solid #000;\''); echo $form-end('Submit'); I'm using a slightly modified helper, habtmCheckBoxes, found here: http://cakeforge.org/snippet/detail.php?type=snippet&id=190 It works like this: function habtmCheckBoxes($rows=array(), $selectedArr=array(), $modelName, $wrapTag='p', $checkedDiv, $uncheckedDiv) {}

• Hibernate: update on parent-child relationship causes duplicate children

  - by TimmyJ

  I have a parent child relationship in which the parent has a collection of children (a set to be specific). The child collection is setup with cascade="all-delete-orphan". When I initially save the parent element everything works as expected. However, when I update the parent and save again, all the children are re-saved. This behavior leads me to believe that the parent is losing its reference to the collection of children, and therefore when persisting all the children are re-saved. It seems the only way to fix this is to not use the setter method of this child collection, but unfortunately this setter is called implicitly in my application (Spring MVC is used to bind a multi-select form element to this collection, and the setter is called by spring on the form submission). Overwriting this setter to not lose the reference (ie, do a colleciton.clear() and collection.addAll(newCollection) rather than collection = newCollection) is apparently a hibernate no-no, as is pointed out here: https://forum.hibernate.org/viewtopic.php?t=956859 Does anyone know how to circumvent this problem? I've posted some of my code below. The parent hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="ReportCriteriaBean" table="masterPkReportCriteria"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <set name="treatmentArms" table="masterPkTreatmentArms" sort="org.fstrf.masterpk.domain.RxCodeComparator" lazy="false" cascade="all-delete-orphan" inverse="true"> <key column="runid"/> <one-to-many class="TreatmentArm"/> </set> </class> </hibernate-mapping> The parent object: public class ReportCriteriaBean{ private Integer id; private Set<TreatmentArm> treatmentArms; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public Set<TreatmentArm> getTreatmentArms() { return treatmentArms; } public void setTreatmentArms(Set<TreatmentArm> treatmentArms) { this.treatmentArms = treatmentArms; if(this.treatmentArms != null){ for(TreatmentArm treatmentArm : this.treatmentArms){ treatmentArm.setReportCriteriaBean(this); } } } The child hibernate configuration: <hibernate-mapping package="org.fstrf.masterpk.domain"> <class name="TreatmentArm" table="masterPkTreatmentArms"> <id name="id" column="id"> <generator class="org.hibernate.id.IncrementGenerator" /> </id> <many-to-one name="reportCriteriaBean" class="ReportCriteriaBean" column="runId" not-null="true" /> <property name="rxCode" column="rxCode" not-null="true"/> </class> </hibernate-mapping> The child object: public class TreatmentArm { private Integer id; private ReportCriteriaBean reportCriteriaBean; private String rxCode; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public ReportCriteriaBean getReportCriteriaBean() { return reportCriteriaBean; } public void setReportCriteriaBean(ReportCriteriaBean reportCriteriaBean) { this.reportCriteriaBean = reportCriteriaBean; } public String getRxCode() { return rxCode; } public void setRxCode(String rxCode) { this.rxCode = rxCode; } }

But when I pass argument to it ( That is in the previous code ) , then it prints a space for any character. What should I do?

• BFS Shortest Path: Edge weight either 1 or 2

  - by Hackster

  I am trying to implement a shortest path algorithm using BFS. That is I am trying to find the shortest path from a specified vertex to every other vertex. However, its a special case where all edge weights are either 1 or 2. I know it could be done with Dijkstra's algorithm but I must use Breadth First Search. So far I have a working version of BFS that searches first for a vertex connected with an edge of weight 1. If it cannot find it, then returns a vertex connected with an edge of weight 2. After thinking about it, this is not the correct way to find the shortest path. The problem is I cannot think of any reasoning why BFS would work with weights 1 or 2, as opposed to any weight. Here is the code: public void addEdge(int start, int end, int weight) { adjMat[start][end] = 1; adjMat[end][start] = 1; edge_weight[start][end] = weight; edge_weight[end][start] = weight; } // ------------------------------------------------------------- public void bfs() // breadth-first search { // begin at vertex 0 vertexList[0].wasVisited = true; // mark it displayVertex(0); // display it theQueue.insert(0); // insert at tail int v2; while( !theQueue.isEmpty() ) // until queue empty, { int v1 = theQueue.remove(); // remove vertex at head // until it has no unvisited neighbors while( (v2=getAdjUnvisitedVertex(v1)) != -1 ){// get one, vertexList[v2].wasVisited = true; // mark it displayVertex(v2); // display it theQueue.insert(v2); // insert it } } // end while(queue not empty) // queue is empty, so we're done for(int j=0; j<nVerts; j++) // reset flags vertexList[j].wasVisited = false; } // end bfs() // ------------------------------------------------------------- // returns an unvisited vertex adj to v -- ****WITH WEIGHT 1**** public int getAdjUnvisitedVertex(int v) { for (int j = 0; j < nVerts; j++) if (adjMat[v][j] == 1 && vertexList[j].wasVisited == false && edge_weight[v][j] == 1){ //System.out.println("Vertex found with 1:"+ vertexList[j].label); return j; } for (int k = 0; k < nVerts; k++) if (adjMat[v][k] == 1 && vertexList[k].wasVisited == false && edge_weight[v][k] == 2){ //System.out.println("Vertex found with 2:"+vertexList[k].label); return k; } return -1; } // end getAdjUnvisitedVertex() // ------------------------------------------------------------- } //////////////////////////////////////////////////////////////// public class BFS{ public static void main(String[] args) { Graph theGraph = new Graph(); theGraph.addVertex('A'); // 0 (start for bfs) theGraph.addVertex('B'); // 1 theGraph.addVertex('C'); // 2 theGraph.addEdge(0, 1,2); // AB theGraph.addEdge(1, 2,1); // BC theGraph.addEdge(2, 0,1); // AD System.out.print("Visits: "); theGraph.bfs(); // breadth-first search System.out.println(); } // end main() } The problem then is, that I don't know why BFS can work for the shortest path problem with edges of weight 1 or 2 as opposed to any edges of any weight. Any help is appreciated. Thanks!

• NHibernate child deletion problem.

  - by JMSA

  Suppose, I have saved some permissions in the database by using this code: RoleRepository roleRep = new RoleRepository(); Role role = new Role(); role.PermissionItems = Permission.GetList(); roleRep .SaveOrUpdate(role); Now, I need this code to delete the PermissionItem(s) associated with a Role when role.PermissionItems == null. Here is the code: RoleRepository roleRep = new RoleRepository(); Role role = roleRep.Get(roleId); role.PermissionItems = null; roleRep .SaveOrUpdate(role); But this is not happening. What should be the correct way to cope with this situation? What/how should I change, hbm-file or persistance code?

• missing table in SQLite with specific version of HTC DESIRE HD

  - by William

  My application has a SQLite database in the asset folder. When the user launches my application, the database is created and the tables too. This works fine with a lot of devices (Nexus One, Htc Magic, SGS, X10… and even Htc Desire HD v2.2). My application works with all versions of Android (tested on my device (1.6, 2.2, 2.2.1 Htc Magic) and on the emulator (v1,5 until v2.3). I have just a problem with HTC DESIRE HD v2.2.1 1.72.405.3. The logcat: android.database.sqlite.SQLiteException: no such table: LISTE: , while compiling: select _id from LISTE at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2833) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2854) at android.app.ActivityThread.access$2300(ActivityThread.java:136) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2179) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:143) at android.app.ActivityThread.main(ActivityThread.java:5068) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) Caused by: android.database.sqlite.SQLiteException: no such table: LISTE: , while compiling: select _id from LISTE at android.database.sqlite.SQLiteCompiledSql.native_compile(Native Method) at android.database.sqlite.SQLiteCompiledSql.compile(SQLiteCompiledSql.java:91) at android.database.sqlite.SQLiteCompiledSql.(SQLiteCompiledSql.java:64) at android.database.sqlite.SQLiteProgram.(SQLiteProgram.java:80) at android.database.sqlite.SQLiteQuery.(SQLiteQuery.java:46) at android.database.sqlite.SQLiteDirectCursorDriver.query(SQLiteDirectCursorDriver.java:53) at android.database.sqlite.SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase.java:1417) at android.database.sqlite.SQLiteDatabase.rawQuery(SQLiteDatabase.java:1387) ... 11 more My application create the database but it doesn’t copy the tables of the file of the asset folder in data\data\packagename\databases\mydatabase.

This code works fine with all devices except the HTC DESIRE HD v2.2.1 1.72.405.3. What problems might exist here for the HTC Desire with the given version above? How can this be remedied?

• Same source, multiple targets with different resources (Visual Studio .Net 2008)

  - by Mike Bell

  A set of software products differ only by their resource strings, binary resources, and by the strings / graphics / product keys used by their Visual Studio Setup projects. What is the best way to create, organize, and maintain them? i.e. All the products essentially consist of the same core functionality customized by graphics, strings, and other resource data to form each product. Imagine you are creating a set of products like "Excel for Bankers", Excel for Gardeners", "Excel for CEOs", etc. Each product has the the same functionality, but differs in name, graphics, help files, included templates etc. The environment in which these are being built is: vanilla Windows.Forms / Visual Studio 2008 / C# / .Net. The ideal solution would be easy to maintain. e.g. If I introduce a new string / new resource projects I haven't added the resource to should fail at compile time, not run time. (And subsequent localization of the products should also be feasible). Hopefully I've missed the blindingly-obvious and easy way of doing all this. What is it? ============ Clarification(s) ================ By "product" I mean the package of software that gets installed by the installer and sold to the end user. Currently I have one solution, consisting of multiple projects, (including a Setup project), which builds a set of assemblies and create a single installer. What I need to produce are multiple products/installers, all with similar functionality, which are built from the same set of assemblies but differ in the set of resources used by one of the assemblies. What's the best way of doing this? ------------ The 95% Solution ----------------- Based upon Daminen_the_unbeliever's answer, a resource file per configuration can be achieved as follows: Create a class library project ("Satellite"). Delete the default .cs file and add a folder ("Default") Create a resource file in the folder "MyResources" Properties - set CustomToolNamespace to something appropriate (e.g. "XXX") Make sure the access modifier for the resources is "Public". Add the resources. Edit the source code. Refer to the resources in your code as XXX.MyResources.ResourceName) Create Configurations for each product variant ("ConfigN") For each product variant, create a folder ("VariantN") Copy and Paste the MyResources file into each VariantN folder Unload the "Satellite" project, and edit the .csproj file For each "VariantN/MyResources" <Compile> or <EmbeddedResource> tag, add a Condition="'$(Configuration)' == 'ConfigN'" attribute. Save, Reload the .csproj, and you're done... This creates a per-configuration resource file, which can (presumably) be further localized. Compile error messages are produced for any configuration that where a a resource is missing. The resource files can be localized using the standard method (create a second resources file (MyResources.fr.resx) and edit .csproj as before). The reason this is a 95% solution is that resources used to initialize forms (e.g. Form Titles, button texts) can't be easily handled in the same manner - the easiest approach seems to be to overwrite these with values from the satellite assembly.

• Find out when all processes in (void) is done?

  Hey. I need to know how you can find out when all processes (loaded) from a - (void) are done, if it's possible. Why?
