• SQL SERVER – Unable to DELETE Project in Data Quality Projects (DQS)

  - by pinaldave

  Here is the email which made me write this blog post. When I write a blog post I write keeping in mind that if the developer is not familiar with the concept he will attempt this on the development server. If due to any reason you attempt it on any other server than your personal server, developer should make sure to have complete confidence on his own expertise and understand the risk behind it.  Well, let us read the email which I received. I have modified it a bit to remove information related to organizational and individual. “I just read your blog post on Beginning DQS. I went ahead and followed every single screenshot and it worked fine. I was able to execute the DQS project successfully. However, the same blog post got me in trouble – a serious trouble. After first successful deployment I went ahead and created a few of my own knowledge base and projects. I played around a bit and then decided to get back to real work. Now we had deployed DQS on production server only, so experiment on production server. Now, when I got back to my work, I forgot to close all the windows. My manager found the window open and have seen my test projects. He has asked me to delete my experiments immediately and have said words which I cannot write to you. Here is the problem. I am not able to delete the project which I have created earlier. I am able to open it and play with it but the delete option is disabled and grayed out (see attached image). Now I believe there is nothing wrong with this project as it was just a test project. Would you please write to my manager that it is not harmful to leave that project there as it is? It is also not using any resources. I think he will believe you.” As I said this kind of email makes me uncomfortable. I do not want someone to execute anything on production server. I often write notes and disclaimer on my post when something is dangerous to execute on production server. However, if someone is not expert with SQL Server and attempts something new on production server, I think the major issue is here with the person (admin) who gave new developer permission to production server. This has to be carefully avoided. Here was my response to the individual. “I cannot write to your manager anything as he has not asked me anything. Honestly I believe he is correct in his behavior as you should have not executed anything on the production server without prior approval and testing on the development server. Any R&D must be done on local box or development box. I suggest you request your manager to prevent access to users who does not need access. If he is a good manager, he might have already implemented by now recent event. I also see your screenshot. Here is the issue: While you were playing with project, you might have closed the project half the way, without completing it. Due to the same reason it is locked. You can open and continue from the same place where you have left the project. If you do not need the project any more. Right click on it, click on unlock the project. This will enable the DELETE option and now you can delete the project. Next time, be safe out there. It may be dangerous to have admin access to production server when not needed.“ I have yet not heard from him but I believe he will take my words positively.

• Json.Net Issues: StackOverflowException is thrown when serialising circular dependent ISerializable object with ReferenceLoopHandling.Ignore

  - by keyr

  I have a legacy application that used binary serialisation to persist the data. Now we wanted to use Json.net 4.5 to serialise the data without much changes to the existing classes. Things were working nice till we hit a circular dependent class. Is there any workaround to solve this problem? Sample code as shown below [Serializable] class Department : ISerializable { public Employee Manager { get; set; } public string Name { get; set; } public Department() { } public Department( SerializationInfo info, StreamingContext context ) { Manager = ( Employee )info.GetValue( "Manager", typeof( Employee ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Manager", Manager ); info.AddValue( "Name", Name ); } } [Serializable] class Employee : ISerializable { [NonSerialized] //This does not work [XmlIgnore]//This does not work private Department mDepartment; public Department Department { get { return mDepartment; } set { mDepartment = value; } } public string Name { get; set; } public Employee() { } public Employee( SerializationInfo info, StreamingContext context ) { Department = ( Department )info.GetValue( "Department", typeof( Department ) ); Name = ( string )info.GetValue( "Name", typeof( string ) ); } public void GetObjectData( SerializationInfo info, StreamingContext context ) { info.AddValue( "Department", Department ); info.AddValue( "Name", Name ); } } And the test code Department department = new Department(); department.Name = "Dept1"; Employee emp1 = new Employee { Name = "Emp1", Department = department }; department.Manager = emp1; Employee emp2 = new Employee() { Name = "Emp2", Department = department }; IList<Employee> employees = new List<Employee>(); employees.Add( emp1 ); employees.Add( emp2 ); var memoryStream = new MemoryStream(); var formatter = new BinaryFormatter(); formatter.Serialize( memoryStream, employees ); memoryStream.Seek( 0, SeekOrigin.Begin ); IList<Employee> deserialisedEmployees = formatter.Deserialize( memoryStream ) as IList<Employee>; //Works nicely JsonSerializerSettings jsonSS= new JsonSerializerSettings(); jsonSS.TypeNameHandling = TypeNameHandling.Objects; jsonSS.TypeNameAssemblyFormat = FormatterAssemblyStyle.Full; jsonSS.Formatting = Formatting.Indented; jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; //This is not working!! //jsonSS.ReferenceLoopHandling = ReferenceLoopHandling.Serialize; //This is also not working!! jsonSS.PreserveReferencesHandling = PreserveReferencesHandling.All; string jsonAll = JsonConvert.SerializeObject( employees, jsonSS ); //Throws stackoverflow exception Edit1: The issue has been reported to Json (http://json.codeplex.com/workitem/23668)

• Issue with Sharepoint 2010 application page

  I am relatively new to Sharepoint and am using version 2010. I am having a problem with the following code in an application page I am trying to build: using System; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Text; using Microsoft.SharePoint.Administration; using Microsoft.Office.Server; using Microsoft.Office.Server.UserProfiles; using Microsoft.SharePoint.Utilities; namespace SharePointProject5.Layouts.SharePointProject5 { public partial class ApplicationPage1 : LayoutsPageBase { protected void Page_Load(object sender, EventArgs e) { SPContext context = SPContext.Current; StringBuilder output = new StringBuilder(); using(SPSite site = context.Site) using (SPWeb web = site.AllWebs["BDC_SQL"]) { UserProfileManager upmanager = new UserProfileManager(ServerContext.GetContext(site)); string ListMgr = ""; string ADMgr = ""; bool allowUpdates = web.AllowUnsafeUpdates; web.AllowUnsafeUpdates = true; web.Update(); SPListCollection listcollection = web.Lists; SPList list = listcollection["BDC_SQL"]; foreach (SPListItem item in list.Items) { output.AppendFormat("<br>From List - Name & manager: {0} , {1}", item["ADName"], item["Manager_ADName"]); UserProfile uProfile = upmanager.GetUserProfile(item["ADName"].ToString()); output.AppendFormat("<br>From Prof - Name & manager: {0} , {1}", uProfile[PropertyConstants.DistinguishedName], uProfile[PropertyConstants.Manager]); ListMgr = item["Manager_ADName"].ToString(); ADMgr = Convert.ToString(uProfile[PropertyConstants.Manager]); if (ListMgr != ADMgr) { output.AppendFormat("<br>This record requires updating from {0} to {1}", uProfile[PropertyConstants.Manager], item["Manager_ADName"]); uProfile[PropertyConstants.Manager].Value = ListMgr; uProfile.Commit(); output.AppendFormat("<br>This record has had its manager updated"); } else { output.AppendFormat("<br>This record does not need to be updated"); } } web.AllowUnsafeUpdates = allowUpdates; web.Update(); } Label1.Text = output.ToString(); } } } Everything worked fine up until I added in the 'uProfile.Commit();' line.

• Dynamic Data: how to filter dropdown for foreign key on edit page

  - by Leonv

  I have Organisation with a foreign key to a Manager. Managers can be active, or inactive. On the Dynamic Data edit page for Organisation, I need to filter the dropdown for Manager to only show active records. I started out by making a custom version of DynamicData\FieldTemplates\ForeignKey_Edit.ascx and setting a UIHint to the new field template on Organisation.Manager. But, how to customize the linq or sql query that runs to load the Managers? Using Linq-to-SQL and DynamicDataFutures

• What do you do when your team leader doesn't know something simple?

  - by leppie

  What do you do when your team leader does not know why the following is wrong: a.SomeProp = a.SomeProp; // no funny side-effects, plain old property He claims 15 years of programming experience, and 7 years of C#/.NET. To me, someone of 3-6 months experience should know this. What I have done: Tried to make him understand why it is wrong. He told me not to criticize him. Told him it's not about criticism, but project risk. He got upset with me. I have addressed the risk of this person with our manager (few weeks back). I have addressed my concerns with this person with our manager several times, since 1 month after I started there (7 months now). Currently, I just feel like just not going back to work... I hardly have any nails left, and this is really just the tip of the iceberg. As nothing has changed after I have spoken to the manager for the last 6 months, I feel like I need to make some sort of ultimatum. Do you have any suggestions? PS: Please do not make this subjective. I have no need for arguing. The level of incompetence is pretty clear. I just need some advice before going insane. Update: Thanks for all the answers (trying to update before close, buggers). I think I will forward this thread to our manager :) Update 2: I sent my manager another mail with my concerns, and a link to this question. Awaiting response.

• Qt QNetworkAccessManager does not emit signals

  - by Emilio

  The function CheckSite() is called with an url like http://site.com, it initializes a QNetworkAccessManager object and connect() slots and signals. The manger-get() call seems work (it generates http traffic) but does not call the slot replyFinished() at the request end. What's wrong with this code? #include <QtCore> #include <QtNetwork> class ClientHandler : public QObject { Q_OBJECT QNetworkAccessManager *manager; private slots: void replyFinished(QNetworkReply *); public: void CheckSite(QString url); }; void ClientHandler::replyFinished(QNetworkReply *reply) { qDebug() << "DONE"; } void ClientHandler::CheckSite(QString url) { QUrl qrl(url); manager = new QNetworkAccessManager(this); connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*))); manager->get(QNetworkRequest(qrl)); }

• How to use Common Table Expression and check no duplication in SQL Server

  - by vodkhang

  I have a table references to itself. User table: id, username, managerid and managerid links back to id Now, I want to get all the managers including direct manager, manager of direct manager, so on and so forth... The problem is that I do not want to have a unstop recursive sql. So, I want to check if an id alreay in a list, I will not include it anymore. Here is my sql for that: with all_managers (id, username, managerid, idlist) as ( select u1.id, u1.username, u1.managerid, ' ' from users u1, users u2 where u1.id = u2.managerid and u2.id = 6 UNION ALL select u.id, u.username, u.managerid, idlist + ' ' + u.id from all_managers a, users u where a.managerid = u.id and charindex(cast(u.id as nvarchar(5)), idlist) != 0 ) select id, username from all_managers; The problem is that in this line: select u1.id, u1.username, u1.managerid, ' ' The SQL Server complains with me that I can not put ' ' as the initialized for idlist. nvarchar(40) does not work as well. I do not know how to declare it inside a common table expression like this one. Usually, in db2, I can just put varchar(40) My sample data: ID UserName ManagerID 1 admin 1 2 a 1 3 b 1 4 c 2 What I want to do is that I want to find all managers of c guy. The result should be: admin, a, b. Some of the user can be his manager (like admin) because the ManagerID does not allow NULL and some does not have direct manager. With common table expression, it can lead to an infinite recursive. So, I am also trying to avoid that situation by trying to not include the id twice. For example, in the 1st iteration, we already have id : 1, so, in the 2nd iteration and later on, 1 should never be allowed. I also want to ask if my current approach is good or not and any other solutions? Because if I have a big database with a deep hierarchy, I will have to initialize a big varchar to keep it and it consumes memory, right?

• Creating Dependencies Only to be able to Unit Test

  - by arin

  I just created a Manager that deals with a SuperClass that is extended all over the code base and registered with some sort of SuperClassManager (SCM). Now I would like to test my Manager that is aware of only the SuperClass. I tried to create a concrete SCM, however, that depends on a third party library and therefore I failed to do that in my jUnit test. Now the option is to mock all instances of this SCM. All is good until now, however, when my Manager deals with the SCM, it returns children of the SuperClass that my Manager does not know or care about. Nevertheless, the identities of these children are vital for my tests (for equality, etc.). Since I cannot use the concrete SCM, I have to mock the results of calls to the appropriate functions of the SCM, however, this means that my tests and therefore my Manager need to know and care about the children of the SuperClass. Checking the code base, there does not seem to be a more appropriate location for my test (that already maintains the appropriate real dependencies). Is it worth it to introduce unnecessary dependencies for the sake of unit testing?

• How can I implement a proper counter bean with EJB 3.0?

  - by Aaron Digulla

  I have this entity bean: import javax.persistence.*; @Entity public class CounterTest { private int id; private int counter; @Id public int getId() { return id; } public void setId(int id) { this.id = id; } public int getCounter() { return counter; } public void setCounter(int counter) { this.counter = counter; } } and this stateful bean to increment a counter: import java.rmi.RemoteException; import javax.ejb.*; import javax.persistence.*; @Stateful public class CounterTestBean implements CounterTestRemote { @PersistenceContext(unitName = "JavaEE") EntityManager manager; public void initDB() { CounterTest ct = new CounterTest(); ct.setNr(1); ct.setWert(1); manager.persist(ct); } public boolean testCounterWithLock() { try { CounterTest ct = manager.find(CounterTest.class, 1); manager.lock(ct, LockModeType.WRITE); int wert = ct.getWert(); ct.setWert(wert + 1); manager.flush(); return true; } catch (Throwable t) { return false; } } } When I call testCounterWithLock() from three threads 500 times each, the counter gets incremented between 13 and 1279 times. How do I fix this code so that it is incremented 1500 times?

• how to specify open id realm in openid4java 0.9.5

  my url @ development : http://192.168.0.1:8888/com.company.MyEntryPoint/MyEntrypoint.html my url @ live env : http://www.example.com/com.company.MyEntryPoint/MyEntrypoint.html I need users to authenticate using open id, this is how i want my realm to be: *.company.MyEntryPoint I wrote a simple code to specify realm: AuthRequest authReq = manager.authenticate( discovered, returnToUrl, "*.company.MyEntryPoint" ); it does not work.

• Jboss logging issue

  - by balaji

  I'm Working as deployer and server administrator. We use Jboss 4.0x AS to deploy our applications. The issue I'm facing is, Whenever we redeploy/restart the server, server.log is getting created but after sometime the logging goes off. Yes it is not at all updating the server.log file. Due to this, we could not trace the other critical issues we have. Actually we have two separate nodes and we do deploy/restarting the server separately on two nodes. We are facing the issue in both of our test and production environment. I could not trace out where exactly the issue is. Could you please help me in resolving the issue? If we have any other issues, we can check the log files. If log itself is not getting updated/logged, how can we move further in analyzing the issues without the recent/updated logs? Below are the logs found in the stdout.log: 18:55:50,303 INFO [Server] Core system initialized 18:55:52,296 INFO [WebService] Using RMI server codebase: http://kl121tez.is.klmcorp.net:8083/ 18:55:52,313 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:log4j.xml 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFTraceLogger without a class name. 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFMessageLogger without a class name. 18:55:54,273 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheTraceLogger without a class name. 18:55:54,274 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheMessageLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCTraceLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCMessageLogger without a class name. 18:55:56,059 INFO [ServiceEndpointManager] WebServices: jbossws-1.0.3.SP1 (date=200609291417) 18:55:56,635 INFO [Embedded] Catalina naming disabled 18:55:56,671 INFO [ClusterRuleSetFactory] Unable to find a cluster rule set in the classpath.

• Handling undo and edit flag on window with several model objects

  - by Rui Pacheco

  Hi, I've a window that will hold several instances of a model object, listed in a table. The model object is updated using a text view. What is the best way to keep the edit flag and undo manager in synch with the content of the different model objects? I'm thinking creating an instance of the undo manager on the model object and manually set the undo manager for the text view every time the user choses a new model object. Does the undo manager also handle the edited flag?

• Fluent Nhibernate Mapping Single class on two database tables

  - by nabeelfarid

  Hi guys, I am having problems with Mapping. I have two tables in my database as follows: Employee and EmployeeManagers Employee EmployeeId int Name nvarchar EmployeeManagers EmployeeIdFk int ManagerIdFk int So the employee can have 0 or more Managers. A manager itself is also an Employee. I have the following class to represent the Employee and Managers public class Employee { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual IList<Employee> Managers { get; protected set; } public Employee() { Managers = new List<Employee>(); } } I don't have any class to represent Manager because I think there is no need for it, as Manager itself is an Employee. I am using autoMapping and I just can't figure out how to map this class to these two tables. I am implementing IAutoMappingOverride for overriding automappings for Employee but I am not sure what to do in it. public class NodeMap : IAutoMappingOverride { public void Override(AutoMapping<Node> mapping) { //mapping.HasMany(x => x.ValidParents).Cascade.All().Table("EmployeeManager"); //mapping.HasManyToMany(x => x.ValidParents).Cascade.All().Table("EmployeeManager"); } } I also want to make sure that an employee can not be assigned the same manager twice. This is something I can verify in my application but I would like to put constraint on the EmployeeManager table (e.g. a composite key) so a same manager can not be assigned to an employee more than once. Could anyone out there help me with this please? Awaiting Nabeel

• MySQL multidimensional arrays...

  - by jay

  What is the best way to store data that is dynamic in nature using MySQL? Let's say I have a table in which one item is "dynamic". For some entries I need to store one value, but for others it could be one hundred values. For example let's say I have the following simple table: CREATE TABLE manager ( name char(50), worker_1_name(50), worker_2_name(50), ... worker_N_name(50) ); Clearly, this is not an ideal way to set up a database. Because I have to accommodate the largest group that a manager could potentially have, I am wasting a lot of space in the database. What I would prefer is to have a table that I can use as a member of another table (like I would do in C++ through inheritance) that can be used by the "manager" table to handle the variable number of employees. It might look something like this. CREATE TABLE manager ( name char(50), underlings WORKERS ); CREATE TABLE WORKERS ( name char(50), ); I would like to be able to add a variable number of workers to each manager. Is this possible or am I constrained to enumerating all the possible number of employees even though I will use the full complement only rarely?

• Aggregate Functions on subsets of data based on current row values with SQL

  Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  I’m Working as deployer and server administrator. We use Jboss 4.0x AS to deploy our applications. The issue I'm facing is, Whenever we redeploy/restart the server, server.log is getting created but after sometime the logging goes off. Yes it is not at all updating the server.log file. Due to this, we could not trace the other critical issues we have. Actually we have two separate nodes and we do deploy/restarting the server separately on two nodes. We are facing the issue in both of our test and production environment. I could not trace out where exactly the issue is. Could you please help me in resolving the issue? If we have any other issues, we can check the log files. If log itself is not getting updated/logged, how can we move further in analyzing the issues without the recent/updated logs? Below are the logs found in the stdout.log: 18:55:50,303 INFO [Server] Core system initialized 18:55:52,296 INFO [WebService] Using RMI server codebase: http://kl121tez.is.klmcorp.net:8083/ 18:55:52,313 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:log4j.xml 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFTraceLogger without a class name. 18:55:52,860 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasRBPFMessageLogger without a class name. 18:55:54,273 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheTraceLogger without a class name. 18:55:54,274 ERROR [STDERR] LOG0026E The Log Manager cannot create the object AmasCacheMessageLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCTraceLogger without a class name. 18:55:54,334 ERROR [STDERR] LOG0026E The Log Manager cannot create the object JACCMessageLogger without a class name. 18:55:56,059 INFO [ServiceEndpointManager] WebServices: jbossws-1.0.3.SP1 (date=200609291417) 18:55:56,635 INFO [Embedded] Catalina naming disabled 18:55:56,671 INFO [ClusterRuleSetFactory] Unable to find a cluster rule set in the classpath.

• Android framework. What is it?

  - by Confused

  I've few questions on Android Framework. Can someone please answer them i) What does an Android Framework do? What is it's job? ii) What are these managers - Activity Manager, Location Manager etc? Are they APIs or libraries? iii) I heard that the definition of a framework is - a set of libraries that say “Don’t call us, we’ll call you.” So can I say that Activity Manager, Location Manager etc are such libraries? Or is it that they are not libraries but APIs (used to access underlying c/c++ libraries) and the actual libraries that do "Don't call us, we'll call you." are hidden from us?

• Codeigniter: Library function--I'm stuck

  - by Kevin Brown

  I have a library function that sets up my forms, and submits data. They're long, and they work, so I'll spare you reading my code. :) I simply need a way for my functions to determine how to handle the data. Until now, the function did one thing: Submit a report for the current user. NOW, the client has requested that an administrator also be able to complete a form--this means that the form would be filled out, and it would CREATE a user at the same time, whereas the current function EDITS and is accessed by an EXISTING user. Do I need a separate function to do essentially the same thing? How do I make one function perform two tasks? One to update a user, and if there is no user, create one. Current controller: function survey() { $id = $this->session->userdata('id'); $data['member'] = $this->home_model->getUser($id); //Convert the db Object to a row array $data['manager'] = $data['member']->row(); $manager_id = $data['manager']->manager_id; $data['manager'] = $this->home_model->getUser($manager_id); $data['manager'] = $data['manager']->row(); $data['header'] = "Home"; $this->survey_form_processing->survey_form($this->_container,$data, $method); } Current Library: function survey_form($container) { //Lots of validation stuff $this->CI->validation->set_rules($rules); if ( $this->CI->validation->run() === FALSE ) { // Output any errors $this->CI->validation->output_errors(); } else { // Submit form $this->_submit(); } $this->CI->load->view($container,$data); The submit function is huge too. Basically says, "Update table with data where user_id=current user" I hope this wasn't too confusing. I'll create two functions if need be, but I'd like to keep redundancy down! }
