• Mapping table and a simple view with Fluent NHibernate

  - by adrin

  I have mapped a simple entity, let's say an invoice using Fluent NHibernate, everything works fine... after a while it turns out that very frequently i need to process 'sent invoices' (by sent invoices we mean all entities that fulfill invoice.sent==true condition)... is there a way to easily abstract 'sent invoices' in terms of my data access layer? I dont like the idea of having aforementioned condition repeated in half of my repository methods. I thought that using a simple filtering view would be optimal, but how could it be done? Maybe I am doing it terribly wrong and someone would help me realize it :)?

• How do I get fluent nhibernate to create a varbinary(max) field in sql server

  - by czk

  Hi, How can I get fluent nhibernate to create a varbinary field in a sql server 2005 table that uses a field size of varbinary(max)? At the moment I always get a default of varbinary(8000), which isn't big enough as i'm going to be storing image files. I've tried using CAstle.ActiveRecord but havent had any success yet. [ActiveRecord] public class MyFile : Entity { public virtual string FileName { get; set; } public virtual string FileType { get; set; } public virtual int FileVersion { get; set; } public virtual int FileLength { get; set; } [Property(ColumnType = "BinaryBlob", SqlType = "VARBINARY(MAX)")] public virtual byte[] FileData { get; set; } } Been failing at finding a solution for hours now, so thanks in advance czk

• Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

  - by gtas

  Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

• Invalid receiver type 'NSUInteger'

  - by CJ

  I have a Core Data entity whose header file looks like this: @interface MyEntity : NSManagedObject { } @property (nonatomic, retain) NSNumber * index; @end And it's implementation file looks like this: @implementation MyEntity @dynamic index; @end Now, I have a piece of code that looks like this: NSArray* selectedObects = [myEntityArrayController selectedObjects]; NSUInteger theIndex = [[[selectedObects objectAtIndex:0] index] unsignedIntegerValue]; The 'myEntityArrayController' object is a NSArrayController which manages all entities of MyEntity. This code executes correctly, however XCode always gives the warning "Invalid receiver type 'NSUInteger'" for the last line of code. For some reason, XCode thinks that the index method returns a NSUInteger. I'm not sure why it thinks this, because 'objectAtIndex' returns an object of type 'id'. I've cleaned the project several times, and these warnings have hung around for a while. Any suggestions are appreciated.

• EF4, MVC 3, Azure and Code First or Traditional

  - by RichardAlanA

  I am planning to build a web application using ASP MVC3 that runs on Azure with a SQL Azure back end. I would like to use the Microsoft stack and have no plans to ever change to another stack. I am looking into the use of WCF and WF but that would be in the future. I looked at the traditional and Code First approach to using Entity Framework but I can't see if there is any advantage in using one or the other approach. Sure they each have advantages but for me I don't care if my classes do inherit from EF classes. All I want is to find the most efficient solution. Can anyone out there give me some advice as to which approach might be the best. thanks very much Richard

• creating new usercntrols at runtime in ASP.NET MVC

  - by Paul Connolly

  Hi everyone, My situation is that the user is creating an entity on my site which contains the particlars of the driectors of that company, name address etc.. The Director form is a separate user control with the appropriate textboxes etc. At run time we don't know how many of these directors there will be so I need one to be able to use something like an "ADD DIRECTOR" or "DELETE DIRECTOR" button which will present or delete the another usercontrol to add the additional director. Currently I am trying to make this happen within a pane of the JQuery Accordion control. I have looked many places for how to do this but to no avail. Can anyone tell me where I might find some inforamation about how I can do this? All the best Paul

• What technical skills needed for algorithmic trading, HFT, etc?

  - by alchemical

  I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

• Application creashing in saveAction of Coredata iphone sdk

  - by neha

  Hi all, In my application I'm inserting data using Coredata like this: GoodWork * newGoodwork = (GoodWork *)[NSEntityDescription insertNewObjectForEntityForName:@"GoodWork" inManagedObjectContext:self.managedObjectContext]; // Step 2: Set Properties [newGoodwork setEletitle:[NSString stringWithFormat:@"%@", aGoodwork.eletitle]]; [newGoodwork setEletxt:[NSString stringWithFormat:@"%@", aGoodwork.eletxt]]; [newGoodwork setSortId:[NSNumber numberWithInt:sortId]]; // Step 3: Save Object [self saveAction]; Everythinng is working fine but in saveAction which is: - (void)saveAction { NSError *error; if (![self.managedObjectContext save:&error]) { NSLog(@"Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } My application is crashing after processing if condition.

• ORA-22835 using JPA (Buffer too small)

  - by Kenneth

  I am trying to persist an Entity with a @Lob annotated String field. The content of that fiels if bigger than the 40k buffer size limit. The first problem I had was related to the setString method used internally by the JPA implementation (Hibernate in my case) and the Oracle JDBC Driver. This problem was solved adding <property name="hibernate.connection.SetBigStringTryClob" value="true"/> to my persistence.xml file. Then, the error changed to a ORA-22835 error (the buffer is too small). ¿Is there any way that JPA solves this problem without going to a low-level implementation? ¿Any suggestions?

• Best practices for fixed-width processing in .NET

  - by jmgant

  I'm working a .NET web service that will be processing a text file with a relatively long, multilevel record format. Each record in the file represents a different entity; the record contains multiple sub-types. (The same record format is currently being processed by a COBOL job, if that gives you a better picture of what we're looking at). I've created a class structure (a DATA DIVISION if you will) to hold the input data. My question is, what best practices have you found for processing large, complex fixed-width files in .NET? My general approach will be to read the entire line into a string and then parse the data from the string into the classes I've created. But I'm not sure whether I'll get better results working with the characters in the string as an array, or with the string itself. I guess that's the specific question, string vs. char[], but I would appreciate any other pointers anyone has. Thanks.

• Small standalone SQL database similar to access in the old days(ie file database)

  - by Ian

  Hi, I am looking for a easy to use and deploy sql type database i can ship with a desktop application. This will be a small application user's can download from my website. In the vb6 days, access was the common database for small desktop apps, what is my option these days? Looking at SQL CE it seems to have a quite a few limitations such as count(distinct) etc SQL express needs to be installed and running as a service (could i include the SQL express deployments in my deployment so the user doesn't even know its been installed? I assume size would then be an issue) SQL 2005/2008 is not an option due to size and licensing restrictions. I would like to use c#, wpf and entity framework. What would seem to be the best options based on your knowledge and experience? Thanks

• How to use PropertyCriteria on complex property?

  - by user1394710

  I'm new to EPiSERVER. Currently trying to search for a page with a specific property set to a specific value. I need the property CatalogEntryPoint (a ContentReference) to equal something. Here is the criterea: PropertyCriteria secCriteria = new PropertyCriteria(); secCriteria.Condition = CompareCondition.Equal; secCriteria.Name = "CatalogEntryPoint.ID"; secCriteria.Type = PropertyDataType.Number; secCriteria.Value = currentContent.ContentLink.ID.ToString(); secCriteria.Required = true; And here is an excerpt from the search index: { "CatalogEntryPoint": { "$type": "EPiServer.Find.Cms.IndexableContentReference, EPiServer.Find.Cms", "ID$$number": 1073742170, "WorkID$$number": 0, "ProviderName$$string": "CatalogContent", "GetPublishedOrLatest$$bool": false, "IsExternalProvider$$bool": true, "___types": [ "EPiServer.Find.Cms.IndexableContentReference", "EPiServer.Core.ContentReference", "System.Object", "System.IComparable", "EPiServer.Data.Entity.IReadOnly" ] }, It would seem that the CatalogEntryPoint.ID-notation does not work as I'm getting 0 results. How should I write it?

• Linq - How to query specific columns and return a lists

  - by Billy Logan

  Hello Everyone, I am trying to write a linq query that will only return certain columns from my entity object into a list object. Below is my code which produces an error(can't implicitly convert a generic list of anonymous types to a generic list of type TBLPROMOTION): List<TBLPROMOTION> promotionInfo = null; promotionInfo = (from p in matches orderby p.PROMOTION_NM descending select new { p.EFFECTIVE_DT, p.EXPIRE_DT, p.IS_ACTIVE, p.PROMOTION_DESC, p.PROMOTION_ID, p.PROMOTION_NM }).ToList(); What would be the best way to accomplish this. I do not want to do a "select p" in this case and return all the columns associated with the query. thanks in advance, Billy

• Using a DataSet instead of custom business entities in soa and n-tier architecture

  - by kathy

  I’m working on a large and a high volume transactional enterprise application which has been designed using n-tire application architecture .And it was developed in the .NET platform utilizing C#,VB.NEt, Framework 3.5, ObjectDataSources, DataSet, WCF, asp.net update panel, JavaScript ,JSON, 3rd Party tools. The application is supposed to accomplish a really scalable / easily maintained / robust application / integrations, and to make sure that my services are created using a format that can be understood by other systems. The problem is, this application is about 70% complete but now I was wondering if the following would cause us future issues, I’m using a DataSet and a DataTable to (get /set) the data (form /to) the stored procedure in the database using the ObjectDataSources and was wondering if this would prevent my application from achieving the above goals. Actually, I am not anti-OO. I write lots of classes for different purposes, but I didn’t use the entity objects(custom business entities) instead of the previous way because I have a large database that may contain 50 tables and I was just afraid to create entities for each table and then in the future if I need to change the schema of the database, it might cause a huge affect on the application ?

• "SELECT ... FOR UPDATE" not working for Hibernate and MySQL

  - by Andres Rodriguez

  Hi, We have a system in which we must use pessimistic locking in one entity. We are using hibernate, so we use LockMode.UPGRADE. However, it does not lock. The tables are InnoDB We have checked that locking works correctly in the database (5.0.32), so this bug http://bugs.mysql.com/bug.php?id=18184 seems to be no problem. We have checked that datasource includes the autoCommit = false parameter. We have checked that the SQL hibernate (version 3.2) generates includes the " FOR UPDATE". Thanks,

• Hibernate annotations cascading doesn't work

  - by user304309

  Hi all, I've decided to change hbm.xml style to annotations using hibernate. I had in my hbm.xml: <hibernate-mapping package="by.sokol.jpr.data"> <class name="Licence"> <id name="licenceId"> <generator class="native" /> </id> <many-to-one name="user" lazy="false" cascade="save-update" column="usr"/> </class> </hibernate-mapping> And changed it to: @Entity public class Licence { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int licenceId; @ManyToOne(targetEntity=User.class, fetch=FetchType.EAGER, cascade = CascadeType.ALL) @Cascade(value = { org.hibernate.annotations.CascadeType.SAVE_UPDATE }) private User user; } And hibernate doesn't save user on saving. I really need help!

• Automatically created NSManagedObject subclasses don't use ARC

  - by Jordan

  My project is ARC enabled (the build settings have Objective-C Reference Counting set to YES). There are no file exceptions to this, it is enabled project wide. (Latest stable version of Xcode). When I create an NSManagedObject subclass via File New for a Core Data entity, the generated header uses the following in its property declarations: @property (nonatomic, retain) But 'retain' is not ARC!! Is this a bug, or is there something I'm missing or not understanding? There are no build warnings - if this is a bug though, how can I remedy it?

• Using OpenSessionInViewInterceptor with Hibernate and JSF 2

  - by sammy

  I'm building an application in Hibernate, Spring and JSF2 using only annotations. How can I take advantage of OpenSessionInViewInterceptor found in Spring to catch any hibernate session that might open within a bean? I'm trying to elegantly solve the common “failed to lazily initialize a collection of role: your.Class.assocation no session or session was closed.” problem when trying to read from a yet uninitialized list of POJOs inside another POJO (A Tag entity retrieved by a DAO that contains a List of Project objects I want to read). I've found this: http://www.paulcodding.com/blog/2008/01/21/using-the-opensessioninviewinterceptor-for-spring-hibernate3/ but failed to make use of it in my environment. Please provide a detailed answer, as the Internet is full of foggy, unhelpful tutorials. I'll also be greatful for an alternative solution, given a step-by-step instruction is provided.

• iPhone: Group by month - Core Data

  - by Shaun

  Hi I store dates in a core data entity attribute, I then display the date in the table cells. I want to group all the cells according to months and only display the relevant dates in the correct sections. I'm using sectionNameKeyPath of the NSFetchedResultsController, but I need to only use the month in the date to group. How can I achieve this? Would I need to create a new attribute and store just the month as a string or can I use NSPredicate? Please can anyone let me know if they have done this or give me some examples. Thanks

• Date only from TextBoxFor()

  - by thekronos

  Hello, I'm having trouble displaying the only date part of a datetime into a textbox using TextBoxFor<,(expression, htmlAttributes). The model is based on Linq2SQL, field is a DateTime on SQL and in the Entity model. Failed : <%= Html.TextBoxFor(model => model.dtArrivalDate, String.Format("{0:dd/MM/yyyy}", Model.dtArrivalDate))%> Ps : this trick seems to be depreciated, any string value in the object htmlAttribute is ignored. Failed : [DisplayFormat( DataFormatString= "{0:dd/MM/yyyy}" )] public string dtArrivalDate { get; set; } I would like to store and display the date part only on the details/edit view without the "00:00:00" part. Any idea please ? Merry Chrismas from France to all by the way ;-)
