• How to add a view on cell.contentview of uitableview iphone sdk

  - by neha

  Hi all, In my application I'm creating a .xib of a class and loading that .xib on cells of uitableview of another class. I want to add this .xib to cell.contentView and not cell. How shall I do that? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString* cellIdentifier = @"testTableCell"; testTableCell * cell = (testTableCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"testTableCell" owner:self options:nil]; cell = tCell; } return cell; } testTableCell is my another class in which I have two labels and two buttons, of which I have created a .xib and loading it to tableview's cell as above. tCell is an object of class testTableCell. Thanks in advance.

• How to Configure SSL over Database in Spring?

  - by Sameer Malhotra

  Hi, I want to add SSL security in the Database layer. I am using Struts2.1.6, Spring 2.5, JBOSS 5.0 and Informix 11.5. Any idea how to do this? I have researched through a lot on the internet but could not find any solution. Please suggest! Here is my datasource and entity manager beans which is working perfect without SSL: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="INFORMIX" /> <property name="showSql" value="true" /> </bean> </property> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.informix.jdbc.IfxDriver" /> <property name="url" value="jdbc:informix-sqli://SERVER_NAME:9088/DB_NAME:INFORMIXSERVER=SERVER_NAME;DELIMIDENT=y;" /> <property name="username" value="username" /> <property name="password" value="password" /> <property name="minIdle" value="2" /> </bean> <bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" lazy-init="false"> <property name="targetObject" ref="dataSource" /> <property name="targetMethod" value="addConnectionProperty" /> <property name="arguments"> <list> <value>characterEncoding</value> <value>UTF-8</value> </list> </property> </bean> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" scope="prototype"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <tx:annotation-driven transaction-manager="transactionManager" />

• Updates to NSDictionary attribute in CoreData not saving

  - by sfkaos

  I have created an Entity in CoreData that includes a Transformable attribute type implemented as an NSDictionary. The NSDictionary attribute only contains values of a custom class. The properties of the custom class are all of type NSString. The custom class complies with NSCoding implementing: -(void)encodeWithCoder:(NSCoder*)coder; -(id)initWithCoder:(NSCoder *)coder When saving the Entity for the first time all attributes including the Transformable (NSDictionary) type are properly saved in the DB. When the same Entity is fetched from the DB and updated (including the Transformable attribute) it seems to be updated properly. However, when the app is closed and then reopened fetching the Entity does not show the updated Transformable attribute-type though the rest of the attributes of type NSDate and NSString are up-to-date. The Transformable attribute is the original saved value not the updated value. Is this a problem with KVO or am I missing something else when trying to save an NSDictionary filled with a custom class to CoreData?

• Nullable<> as TModel for ViewPage

  - by Alexander Prokofyev

  What are the possible reasons what Nullable<> types are disallowed to be passed as TModel parameter of System.Web.Mvc.ViewPage<TModel> generic? This could be handy sometimes. In ASP.NET MVC source defined what TModel should be a class: public class ViewPage<TModel> : ViewPage where TModel : class but Nullable types are value types. Maybe definition could be less restrictive...

• Using Mate's RemoteObjectInvoker with C# classes

  - by FigBug

  I'm using the Mate framework for Flex and communicating with a server running C#. I'm having trouble mapping C# classes to ActopnScript classes. I've got it working fine for simple classes and built in datatypes. If I have a C# method in my API that returns a API.Foo.Result what name do I use for my RemoteClass alias? Do I need to make a separate ActionScript class for each variation of the API.Foo.Result? How do I call C# method that takes a class as a parameter? Making an ActionScript class with members with the same names doesn't seem to work. What is the best way to handle C# classes that contain arrays of objects? The seem to get converted to ArrayCollections of Object. Is there a way to get them converted to an ArrayCollection of my specific class?

• Design Layout/Patterns

  - by wpfwannabe

  I am still fairly new to C# and I am trying to decide the best way to structure a new program. Here is what I want to do and I would like feed back on my idea. Presentation Layer Business Layer (Separate Class Library) Data Layer (Separate Class Library) Model Layer (Separate Class Library) What I am struggling with is if it is ok to have the classes in the Data Layer and Business Layer inherit from the types I define in Model Layer. This way I can extended the types as needed in my Business Layer with any new properties I see fit. I might not use every property from the Model type in my Business Layer class but is that really a big deal? If this isn't clear enough I can try and put together an example.

• A question about John Resig's Simple Javascript Inheritance.

  - by Zippo

  I'm using this simple code: http://ejohn.org/blog/simple-javascript-inheritance/ Using this "library", I made this simple class: var Person = Class.extend({ init: function(openningSentence) { this.say(openningSentence); }, say: function(words) { alert(words); } }); The problem with this class, is that I can't call a function using the variable "this" (line 3 in the code gives an error: unknown method "say"). Does anybody knoes if there's a solution for this problem? Btw - I'm using jquery, so if there's a jquery-based solution It'll be great :)

• accessing associations within GORM Events

  - by Don

  Hi, My Grails app has a User class and a Role class. The User class has an authorities property which holds the roles assigned to that user, e.g. class User { static hasMany = [authorities: Role] // This method is called automatically after a user is inserted def afterInsert() { this.authorities.size() } } If I create a user and assign them a role, a NullPointerException is thrown from the GORM event method afterInsert(), because authorities is null. If I comment out afterInsert() the user is saved correctly along with the assigned role. Is there some reason why I can't access associations from GORM event methods. Is is possible that this event is fired after the User row is inserted, but before the row is added to the User-Role join table? Thanks, Don

• Is this way of storing typed objects in memory good?

  - by Pindatjuh

  This is an "is this okay, or can it be done better" question. Topic: Storing typed objects in memory. Background information: I'm building a compiler for the x86-32 platform for my language. My goal includes typed objects. Idea: Every primitive is a semi-class (it can be used as if it was a normal class, but it's stored more compact). Every class is represented by primitives and some meta-data (containing class-properties, inheritance stuff, etc.). The meta-data is complex: it doesn't use fields but instead context-switches. For primitives, the meta-data is very small, compared to a "real" class, which is alot bigger. This enables another idea that "primitives are objects", in my language, which I found nessecairy. Example: If I have an array of 32 booleans, then the pure content of this array is exactly 4 byte (32 bits of booleans). The meta-data will contain flags that the type is an array of booleans, which contains 32 entries. The meta-data is very compacted, on bit-level: using a sort of "packing" mechanism, which is read by a FSM at runtime, when doing inspection of the type (like when passing the object to methods for checking, etc.) For instance (read from left to right, top to bottom, remember vertical possition when going to the right, and check nearest column header for meaning of switch): Primitive? Array? Type-Meta 1 Byte? || Size (1 byte) 1 1 [...] 1 [...] done 0 2 Bytes? || Size (2 bytes) 1 [...] done || Size (4 bytes) 0 [...] done Integer? 1 Byte? 2 Bytes? 0 1 0 1 done 1 done 0 done Boolean? Byte? 0 1 0 done 1 done More-Primitives 0 .... Class-Stuff (Huge) 0 ... (After reaching done the data is inserted. || = byte alignement. [...] is variable sized. ... is not described here, for simplicity. And let's call them cost-based-data-structures.) For an array of 32 booleans containing all true values, the memory for this type would be (read top-down): 1 Primitive 1 Array 1 ArrayType: Primitive 0 Not-Array 0 Not-Integer 1 Boolean 0 Not-Byte (thus bit) 1 Integer Size: 1 Byte 00100000 Array size 11111111 11111111 11111111 11111111 Data Thus, 8 bytes represent 32 booleans in an array: 11100101 00100000 11111111 11111111 11111111 11111111 Is this okay, or can it be done better?

• Spring - How do you set Enum keys in a Map with annotations

  - by al nik

  Hi all, I've an Enum class public enum MyEnum{ ABC; } than my 'Mick' class has this property private Map<MyEnum, OtherObj> myMap; I've this spring xml configuration. <util:map id="myMap"> <entry key="ABC" value-ref="myObj" /> </util:map> <bean id="mick" class="com.x.Mick"> <property name="myMap" ref="myMap" /> </bean> and this is fine. I'd like to replace this xml configuration with Spring annotations. Do you have any idea on how to autowire the map? The problem here is that if I switch from xml config to the @Autowired annotation (on the myMap attribute of the Mick class) Spring is throwing this exception nested exception is org.springframework.beans.FatalBeanException: Key type [class com.MyEnum] of map [java.util.Map] must be assignable to [java.lang.String] Spring is no more able to recognize the string ABC as a MyEnum.ABC object. Any idea? Thanks

• subclassing and data contracts

  - by Sergio Romero

  I'm playing with the following code: [ServiceContract] public interface IUserAccountService { [OperationContract] UserAccountResponse CreateNewUserAccount(UserAccountRequest userAccountRequest); } public abstract class BaseResponse { public bool Success { get; set; } public string Message { get; set; } } public class UserAccountResponse : BaseResponse { public int NewUserId { get; set; } } My questions are: Do I need to add the DataContract attribute to both the abstract class and the subclass? If the abstract class does not need the DataContract attribute, can I add the DataMember attribure to its properties?

• JAXB marshals XML differently to OutputStream vs. StringWriter

  - by Andy

  I apologize if this has been answered, but the search terms I have been using (i.e. JAXB @XmlAttribute condensed or JAXB XML marshal to String different results) aren't coming up with anything. I am using JAXB to un/marshal objects annotated with @XmlElement and @XmlAttribute annotations. I have a formatter class which provides two methods -- one wraps the marshal method and accepts the object to marshal and an OutputStream, the other just accepts the object and returns the XML output as a String. Unfortunately, these methods do not provide the same output for the same objects. When marshaling to a file, simple object fields internally marked with @XmlAttribute are printed as: <element value="VALUE"></element> while when marshaling to a String, they are: <element value="VALUE"/> I would prefer the second format for both cases, but I am curious as to how to control the difference, and would settle for them being the same regardless. I even created one static marshaller that both methods use to eliminate different instance values. The formatting code follows: /** Marker interface for classes which are listed in jaxb.index */ public interface Marshalable {} /** Local exception class */ public class XMLMarshalException extends BaseException {} /** Class which un/marshals objects to XML */ public class XmlFormatter { private static Marshaller marshaller = null; private static Unmarshaller unmarshaller = null; static { try { JAXBContext context = JAXBContext.newInstance("path.to.package"); marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8"); unmarshaller = context.createUnmarshaller(); } catch (JAXBException e) { throw new RuntimeException("There was a problem creating a JAXBContext object for formatting the object to XML."); } } public void marshal(Marshalable obj, OutputStream os) throws XMLMarshalException { try { marshaller.marshal(obj, os); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } public String marshalToString(Marshalable obj) throws XMLMarshalException { try { StringWriter sw = new StringWriter(); marshaller.marshal(obj, sw); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } } /** Example data */ @XmlType @XmlAccessorType(XmlAccessType.FIELD) public class Data { @XmlAttribute(name = value) private String internalString; } /** Example POJO */ @XmlType @XmlRootElement(namespace = "project/schema") @XmlAccessorType(XmlAccessType.FIELD) public class Container implements Marshalable { @XmlElement(required = false, nillable = true) private int number; @XmlElement(required = false, nillable = true) private String word; @XmlElement(required = false, nillable = true) private Data data; } The result of calling marshal(container, new FileOutputStream("output.xml")) and marshalToString(container) are as follows: Output to file <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"></data> </ns2:container> and Output to String <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"/> </ns2:container>

Both call a method from another class, one works perfectly fine and the other gives the error java.lang.ClassNotFoundException and the error java.lang.NoClassDefFoundError: com/google/common/base/Predicate The class path should be the same for both as they are in he same package so I can't figure out why one has access to the class and the other doesn't? thanks in advance for any help given.

• Django model manager didn't work with related object when I do aggregated query

  - by Satoru.Logic

  Hi, all. I'm having trouble doing an aggregation query on a many-to-many related field. Let's begin with my models: class SortedTagManager(models.Manager): use_for_related_fields = True def get_query_set(self): orig_query_set = super(SortedTagManager, self).get_query_set() # FIXME `used` is wrongly counted return orig_query_set.distinct().annotate( used=models.Count('users')).order_by('-used') class Tag(models.Model): content = models.CharField(max_length=32, unique=True) creator = models.ForeignKey(User, related_name='tags_i_created') users = models.ManyToManyField(User, through='TaggedNote', related_name='tags_i_used') objects_sorted_by_used = SortedTagManager() class TaggedNote(models.Model): """Association table of both (Tag , Note) and (Tag, User)""" note = models.ForeignKey(Note) # Note is what's tagged in my app tag = models.ForeignKey(Tag) tagged_by = models.ForeignKey(User) class Meta: unique_together = (('note', 'tag'),) However, the value of the aggregated field used is only correct when the model is queried directly: for t in Tag.objects.all(): print t.used # this works correctly for t in user.tags_i_used.all(): print t.used #prints n^2 when it should give n Would you please tell me what's wrong with it? Thanks in advance.

• Help understanding the Single Responsibility Principle

  - by user204588

  I'm trying to understand what a responsibility actually is so I want to use an example of something I'm currently working on. I have a app that imports product information from one system to another system. The user of the apps gets to choose various settings for which product fields in one system that want to use in the other system. So I have a class, say ProductImporter and it's responsibility is to import products. This class is large, probably too large. The methods in this class are complex and would be for example, getDescription. This method doesn't simply grab a description from the other system but sets a product description based on various settings set by the user. If I were to add a setting and a new way to get a description, this class could change. So, is that two responsibilities? Is there one that imports products and one that gets a description. It would seem this way, almost every method I have would be in it's own class and that seems like overkill. I really need a good description of this principle because it's hard for me to completely understand. I don't want needless complexity.

• PHP-FPM Pool, Child Processes and Memory Consumption

  In my PHP-FPM configuration I have 3 Pools, the eg: Config is: ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 1 ; ;;;;;;;;;;;;;;;;;;;;;;; [www1] user = www group = www listen = /tmp/php-fpm1.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 2 ; ;;;;;;;;;;;;;;;;;;;;;;; [www2] user = www group = www listen = /tmp/php-fpm2.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 3 ; ;;;;;;;;;;;;;;;;;;;;;;; [www3] user = www group = www listen = /tmp/php-fpm3.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 I calculated the pm.max_children processes according to some example calculations on the web like 40 x 40 Mb = 1600 Mb. I have separated 4 GB of RAM for PHP, now according to the calculations 40 Child Processes via one socket, and I have total of 3 sockets in my Nginx and FPM configuration. My doubt is about the amount of memory consumption by those child processes. I tried to create high load in the server via httperf hog and siege but I could not calculate the accurate memory usage by all the PHP processes (other processes like MySQL and Nginx were also running). And all the sockets were in use, So, I seek guidance from anyone who have done this before or know how exactly the pm.max_children in PHP Works. Since I have 3 Pools/sockets with 40 child processes does that count to 3 x 40 x 40 Mb of Memory usage ? or it is just like 40 Max. Child processes sharing 3 sockets (and the total memory usage is just 40 x 40 Mb) ?

  Hi, I have a class: public class User { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IDictionary<string, string> Attributes { get; set; } } and a mapping file: <class name="User" table="Users"> <id name="Id"> <generator class="hilo"/> </id> <property name="Name"/> <map name="Attributes" table="UserAttributes"> <key column="UserId"/> <index column="AttributeName" type="System.String"/> <element column="Attributevalue" type="System.String"/> </map> </class> So now I can add many attributes and values to a User. How can I query those attributes so I can get ie. Get all the users where attributename is "Age" and attribute value is "20" ? I don't want to do this in foreach because I may have millions of users each having its unique attributes. Please help

• NHibernate Mapping and Querying Where Tables are Related But No Foreign Key Constraint

  - by IanT8

  I'm fairly new to NHibernate, and I need to ask a couple of questions relating to a very frequent scenario. The following simplified example illustrates the problem. I have two tables named Equipment and Users. Users is a set of system administrators. Equipment is a set of machinery. Tables: Users table has UserId int and LoginName nvarchar(64). Equipment table has EquipId int, EquipType nvarchar(64), UpdatedBy int. Behavior: System administrators can make changes to Equipment, and when they do, the UpdatedBy field of Equipment is "normally" set to their User Id. Users can be deleted at any time. New Equipment items have an UpdatedBy value of null. There's no foreign key constraint on Equipment.UpdatedBy which means: Equipment.UpdatedBy can be null. Equipment.UpdatedBy value can be = existing User.UserId value Equipment.UpdatedBy value can be = non-existent User.UserId value To find Equipment and who last updated the Equipment, I might query like this: select E.EquipId, E.EquipName, U.UserId, U.LoginName from Equipment E left outer join Users U on. E.UpdatedBy = U.UserId Simple enough. So how to do that in NHibernate? My mappings might be as follows: <?xml version="1.0" encoding="utf-8"?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Data" assembly="Data"> <class name="User" table="Users"> <id name="Id" column="UserId" unsaved-value="0"> <generator class="native" /> </id> <property name="LoginName" unique="true" not-null="true" /> </class> <class name="Equipment" table="Equipment"> <id name="Id" column="EquipId" type="int" unsaved-value="0"> <generator class="native" /> </id> <property name="EquipType" /> <many-to-one name="UpdatedBy" class="User" column="UpdatedBy" /> </class> </hibernate-mapping> So how do I get all items of equipment and who updated them? using (ISession session = sessionManager.OpenSession()) { List<Data.Equipment> equipList = session .CreateCriteria<Data.Equipment>() // Do I need to SetFetchmode or specify that I // want to join onto User here? If so how? .List<Data.Equipment>(); foreach (Data.Equipment item in equipList) { Debug.WriteLine("\nEquip Id: " + item.Id); Debug.WriteLine("Equip Type: " + item.EquipType); if (item.UpdatedBy.Country != null) Debug.WriteLine("Updated By: " + item.UpdatedBy.LoginName); else Debug.WriteLine("Updated by: Nobody"); } } When Equipment.UpdatedBy = 3 and there is no Users.UserId = 3, the above fail I also have a feeling that the generated SQL is a select all from Equipment followed by many select columns from Users where UserId = n whereas I'd expected NHibernate to left join as per my plain ordinary SQL and do one hit. If I can tell NHibernate to do the query in one hit, how do I do that? Time is of the essence on my project, so any help you could provide is gratefully received. If you're speculating about how NHibernate might work in this scenario, please say you're not absolutely sure. Many thanks.
