• Rethinking Oracle Optimizer Statistics for P6 Part 2

  - by Brian Diehl

  In the previous post (Part 1), I tried to draw some key insights about the relationship between P6 and Oracle Optimizer Statistics.  The first is that average cardinality has the greatest impact on query optimization and that the particular queries generated by P6 are more likely to use this average during calculations. The second is that these are statistics that are unlikely to change greatly over the life of the application. Ultimately, our goal is to get the best query optimization possible.  Or is it? Stability No application administrator wants to get the call at 9am that their application users cannot get there work done because everything is running slow. This is a possibility with a regularly scheduled nightly collection of statistics. It may not just be slow performance, but a complete loss of service because one or more queries are optimized poorly. Ideally, this should not be the case. The database optimizer should make better decisions with more up-to-date data. Better statistics may give incremental performance benefit. However, this benefit must be balanced against the potential cost of system down time.  It is stability that we ultimately desire and not absolute optimal performance. We do want the benefit from more accurate statistics and better query plans, but not at the risk of an unusable system. As a result, I've developed the following methodology around managing database statistics for the P6 database.  1. No Automatic Re-Gathering - The daily, weekly, or other interval of statistic gathering is unlikely to be beneficial. Quite the opposite. It is more likely to cause problems. 2. Smart Re-Gathering - The time to collect statistics is when things have changed significantly. For a new installation of P6, this is happening more often because the data is growing from a few rows to thousands and more. But for a mature system, the data is not changing significantly from week-to-week. There are times to collect statistics: New releases of the application Changes in the underlying hardware or software versions (ex. new Oracle RDBMS version) When additional user groups are added. The new groups may use the software in significantly different ways. After significant changes in the data. This may be monthly, quarterly or yearly.  3. Always Test - If you take away one thing from this post, it would be to always have a plan to test after changing statistics. In reality, statistics can be collected as often as you desire provided there are tests in place to verify that performance is the same or better. These might be automated tests or simply a manual script of application functions. 4. Have a Way Out - Never change the statistics without a way to return to the previous set. Think of the statistics as one part of the overall application code that also includes the source code--both application and RDBMS. It would be foolish to change to the new code without a way to get back to the previous version. In the final post, I will talk about the actual script I created for P6 PMDB and possible future direction for managing query performance.

• Iterate over rows/checkboxes in a RadGrid

  - by ChessWhiz

  Hi, I have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows: <telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn"> <ItemTemplate> <asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox> </ItemTemplate> </telerik:GridTemplateColumn> I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this: // read all values from database first, then... foreach(var chkbox in MyRadGrid.MasterTableView.Columns.FindByUniqueName("MyTemplateColumn").FindControl("MyCheckBox")) { chkbox.Checked = oneValue; } That doesn't work, because FindControl isn't a method of GridColumn, and it won't generate an iterable list of the checkboxes. What is the correct way to iterate through the checkboxes in the template column? Thanks!

• Exception "The operation is not valid for the state of the transaction" using TransactionScope

  - by Lanfear

  We have a web service on server #1 and a database on server #2. Web service uses transaction scope to produce distributed transaction. Everything is correct. And we have another database on server #3. We had some problems with this server and we reinstalled operation system and software. We configured MSDTC and tried to use web service from server #1 to communicate with database on this server. And now after first select statement within transaction scope we get: "The operation is not valid for the state of the transaction". This exception falls in every web service request if it is using transaction scope. Server #2 and Server #3 is almost similar. The difference can be only in settings. .NET framework 3.5 SP1 installed and SQL Server SP3 on all servers. Full stacktrace: System.Transactions.TransactionState.EnlistPromotableSinglePhase(InternalTransaction tx, IPromotableSinglePhaseNotification promotableSinglePhaseNotification, Transaction atomicTransaction) ?

So what settings should I check and what exactly should I do to fix it?

• Moq Testing a private method .Many posts but still cannot make one example work

  - by devnet247

  Hi, I have seen many posts and questions about "Mocking a private method" but still cannot make it work and not found a real answer. Lets forget the code smell and you should not do it etc.... From what I understand I have done the following: 1) Created a class Library "MyMoqSamples" 2) Added a ref to Moq and NUnit 3) Edited the AssemblyInfo file and added [assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")] [assembly: InternalsVisibleTo("MyMoqSamples")] 4) Now need to test a private method.Since it's a private method it's not part of an interface. 5) added the following code [TestFixture] public class Can_test_my_private_method { [Test] public void Should_be_able_to_test_my_private_method() { //TODO how do I test my DoSomthing method } } public class CustomerInfo { public string Name { get; set; } public string Surname { get; set; } } public interface ICustomerService { List<CustomerInfo> GetCustomers(); } public class CustomerService: ICustomerService { public List<CustomerInfo> GetCustomers() { return new List<CustomerInfo> {new CustomerInfo {Surname = "Bloggs", Name = "Jo"}}; } protected virtual void DoSomething() { } } Could you provide me an example on how you would test my private method? Thanks a lot

• InvalidOperationException when calling SaveChanges in .NET Entity framework

  - by Pär Björklund

  Hi, I'm trying to learn how to use the Entity framework but I've hit an issue I can't solve. What I'm doing is that I'm walking through a list of Movies that I have and inserts each one into a simple database. This is the code I'm using private void AddMovies(DirectoryInfo dir) { MovieEntities db = new MovieEntities(); foreach (DirectoryInfo d in dir.GetDirectories()) { Movie m = new Movie { Name = d.Name, Path = dir.FullName }; db.AddToMovies(movie); } db.SaveChanges(); } When I do this I get an exception at db.SaveChanges() that read. 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: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. I haven't been able to find out what's causing this issue. My database table contains three columns Id int autoincrement Name nchar(255) Path nchar(255) Update: I Checked my edmx file and the SSDL section have the StoreGeneratedPattern="Identity" as suggested. I also followed the blog post and tried to add ClientAutoGenerated="true" and StoreGenerated="true" in the CSDL as suggested there. This resulted in compile errors ( Error 5: The 'ClientAutoGenerated' attribute is not allowed.). Since the blog post is from 2006 and it has a link to a follow up post I assume it's been changed. However, I cannot read the followup post since it seems to require an msdn account.

• Mixed surrogate composite key insert in JPA 2.0, PostgreSQL and Hibernate 3.5

  - by Gerald

  First off, we are using JPA 2.0 and Hibernate 3.5 as persistence provider on a PostgreSQL database. We successfully use the sequence of the database via the JPA 2.0 annotations as an auto-generated value for single-field-surrogate-keys and all works fine. Now we are implementing a bi-temporal database-scheme that requires a mixed key in the following manner: Table 1: id (pk, integer, auto-generated-sequence) validTimeBegin (pk, dateTime) validTimeEnd (dateTime) firstName (varChar) Now we have a problem. You see, if we INSERT a new element, the field id is auto-generated and that's fine. Only, if we want to UPDATE the field within this scheme, then we have to change the validTimeBegin column WITHOUT changing the id-field and insert it as a new row like so: BEFORE THE UPDATE OF THE ROW: |---|-------------------------|-------------------------|-------------------| | id| validTimeBegin | validTimeEnd | firstName | |---|-------------------------|-------------------------|-------------------| | 1| 2010-05-01-10:00:00.000 | NULL | Gerald | |---|-------------------------|-------------------------|-------------------| AFTER THE UPDATE OF THE ROW happening at exactly 2010-05-01-10:35:01.788 server-time: (we update the person with the id:1 to reflect his new first name...) |---|-------------------------|-------------------------|-------------------| | id| validTimeBegin | validTimeEnd | firstName | |---|-------------------------|-------------------------|-------------------| | 1| 2010-05-01-10:00:00.000 | 2010-05-01-10:35:01.788 | Gerald | |---|-------------------------|-------------------------|-------------------| | 1| 2010-05-01-10:35:01.788 | NULL | Jerry | |---|-------------------------|-------------------------|-------------------| So our problem is, that this doesn't work at all using an auto-generated-sequence for the field id because when inserting a new row then the id ALWAYS is auto-generated although it really is part of a composite key which should sometimes behave differently. So my question is: Is there a way to tell hibernate via JPA to stop auto-generating the id-field in the case I want to generate a new variety of the same person and go on as usual in every other case or do I have to take over the whole id-generation with custom code? Thanks in advance, Gerald

• NHibernate SubclassMap gives DuplicateMappingException

  - by stiank81

  I'm using NHibernate to handle my database - with Fluent configuration. I'm not using Automappings. All mappings are written explicitly, and everything is working just fine. Now I wanted to add my first mapping to a subclass, using the SubclassMap, and I run into problems. With the simplest possible setup an Nhibernate DuplicateMappingException is thrown, saying that the subclass is mapped more than once: NHibernate.MappingException : Could not compile the mapping document: (XmlDocument) ---- NHibernate.DuplicateMappingException : Duplicate class/entity mapping MyNamespace.SubPerson I get this with my simple classes written for testing: public class Person { public int Id { get; set; } public string Name { get; set; } } public class SubPerson : Person { public string Foo { get; set; } } With the following mappings: public class PersonMapping : ClassMap<Person> { public PersonMapping() { Not.LazyLoad(); Id(c => c.Id); Map(c => c.Name); } } public class SubPersonMapping : SubclassMap<SubPerson> { public SubPersonMapping() { Not.LazyLoad(); Map(m => m.Foo); } } Any idea why this is happening? If there were automappings involved I guess it might have been caused by the automappings adding a mapping too, but there should be no automapping. I create my database specifying a fluent mapping: private static ISession CreateSession() { var cfg = Fluently.Configure(). Database(SQLiteConfiguration.Standard.ShowSql().UsingFile("unit_test.db")). Mappings(m => m.FluentMappings.AddFromAssemblyOf<SomeClassInTheAssemblyContainingAllMappings>()); var sessionSource = new SessionSource(cfg.BuildConfiguration().Properties, new TestModel()); var session = sessionSource.CreateSession(); _sessionSource.BuildSchema(session); return session; } Again; note that this only happens with SubclassMap. ClassMap's are working just fine!

• Windows 7 - Enable Network DTC Access

  - by Russ Clark

  I have a Visual Studio 2010 Windows Forms application in which I start a transaction using the TransactionScope class. I then Receive a message from a Sql Server Broker Services message queue, which works fine. I next try to call a stored procedure from the same database with a call to my data access layer which is a Visual Studio dataset (xsd file). When I make this second call to the database I get the following error message: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B). I've seen several posts on the web that talk about Enabling DTC access through dcomcnfg.exe, and allowing DTC to communicate through Windows Firewall. I've done those things, and am still having this problem. I know our remote database server is setup to Enable DTC access, because we are using similar transactions in other projects built with Visual Studio 2008 on Windows XP and Vista. I think there is something specific about Windows 7 and Visual Studio 2010 causing this problem, but haven't been able to find out what it is. Can anyone help with this problem?

• Pass dataset to subreport with SQL Server Reporting Services

  - by Juliet

  I'm using SQL Server Reporting Services and the report designer that comes with Visual Studio. I've got a really big report. It's actually so large that Visual Studio hangs (sometimes for hours at a time) or just crashes when I make changes. There is preciously little I can do to solve the problem, so I've decided to just move the bottom half of the report into a sub-report. So, I started with one enormous, unresponsive report and ended with two small, manageable reports -- surprisingly, this actually works. One problem: my subreport uses the same data as my main report. Right now, it populates its dataset by re-querying the database. The extra round-trip to the database causes the report to take twice as long to generate; up from 45 minutes to 1 1/2 hours to generate. I'd like to avoid hitting the database again, and instead use the same dataset in both reports. How can I share or pass a dataset between a report and subreport?

• EF 4, POCO and AddOrUpdate

  - by Eric J.

  I'm trying to create a method on an EF 4 POCO repository called AddOrUpdate. The idea is that the business layer can pass in a POCO object and the persistence framework will add the object if it is new (not yet in the database), else will update the database (once SaveChanges() is called) with the new value. This is similar to some other questions I have asked about EF, but I'm only about 80% there in understanding this so please forgive partial duplication. The part I'm missing is how to update the object graph in my ObjectContext/associated ObjectSet for the passed-in business object once I have determined that the business object indeed already exists in the database (and now has been loaded thanks to TryGetObjectByKey). ApplyCurrentValues sounds sort of like what I want, but it only copies scalar values and doesn't seem intended to update the object graph in the ObjectContext/ObjectSet. Because of my particular use case I don't care about concurrency right now. public void AddOrUpdate(BO biz) { object obj; EntityKey ek = Ctx.CreateEntityKey(mySetName, biz); bool found = Ctx.TryGetObjectByKey(ek, out obj); if (found) { // How do I do what this method name implies? Biz is a parent with children. mySet.TellTheSetToUpdateThisObject(biz); } else { mySet.AddObject(biz); } Ctx.DetectChanges(); }

• WPF Richtextbox XamlWriter behaviour

  - by Krishna

  I am trying to save some c# source code into the database. Basically I have a RichTextBox that users can type their code and save that to the database. When I copy and paste from the visual studio environment, I would like to preserve the formating etc. So I have chosen to save the FlowDocuments Xaml to the database and set this back to the RichTextBox.Document. My below two function serialise and deserialise the RTB's contents. private string GetXaml(FlowDocument document) { if (document == null) return String.Empty; else{ StringBuilder sb = new StringBuilder(); XmlWriter xw = XmlWriter.Create(sb); XamlDesignerSerializationManager sm = new XamlDesignerSerializationManager(xw); sm.XamlWriterMode = XamlWriterMode.Expression; XamlWriter.Save(document, sm ); return sb.ToString(); } } private FlowDocument GetFlowDocument(string xamlText) { var flowDocument = new FlowDocument(); if (xamlText != null) flowDocument = (FlowDocument)XamlReader.Parse(xamlText); // Set return value return flowDocument; } However when I try to serialise and deserialise the following code, I am noticing this incorrect(?) behaviour using System; public class TestCSScript : MarshalByRefObject { } Serialised XAML is using System; public class TestCSScript : MarshalByRefObject {}{ } Notice the the new set of "{}" What am I doing wrong here... Thanks in advance for the help!

• AndroMDA maven code generation and JPA Annotations

  - by ArsenioM

  I am using the AndroMDA plugin for maven to generate code from an uml diagram made in MagicDraw. When the code is generated, AndroMDA desings the JPA annotation for the persitence layer. I think that at the compilation process AndroMDA uses Naming Strategies to determine the Table and Column names for the DataBase. I want to determine how AndroMDA desings this JPA annotations, because I need to display this DataBase names based on the UML entity and atributtes names. I was regarding if there is an API of AndroMDA that I could use to do this by giving it the uml diagram. Or at least, to know the Naming Strategies used by AndroMDA to achive that. AndroMDA at the compilation process design the JPA annotations for the Entities, Attributes, etc that are written in my java classes under a series of rules that exist within the EJB3 cartridge of AndroMDA. (The further Database is created using those JPA annotations). I want to create a program that returns me the same Table and Attributes names wrote on the JPA annotations, by giving it the .xml file of the uml diagram of a project. I was hoping that I could take advantage of the EJB3 cartridge to generate those Tables and Attribute names with my program. One way could be using an API of AndroMDA that do this(if it exits), or at least, by implementing the same rules used by the EJB3 cartridge for that matter. To be more illustrative, For example: If in my uml model I have an Entity called “CompanyGroup”, AndroMDA would generate the following code for the class definition: @javax.persistence.Entity @javax.persistence.Table(name = "COMPANY_GR") Public class CompanyGroup implements java.io.Serializable, Comparable< CompanyGroup This is just an example (not a real case), but nevertheless, the way how AndroMDA do the translation from “CompanyGroup” to “COMPANY_GR” has to be specified somewhere. Hope this explanation is useful enough. Thanks.

• DataGridView row is still dirty after committing changes

  - by Ecyrb

  DataGridView.IsCurrentRowDirty remains true after I commit changes to the database. I want to set it to false so it doesn't trigger RowValidating when it loses focus. I have a DataGridView bound to a BindingList<T>. I handle the CellEndEdit event and save changes to the database. After saving those changes I would like DataGridView.IsCurrentRowDirty to be set to true, since all cells in the row are up-to-date; however, it's set to false. This causes problems for me because when the row does lose focus it will trigger RowValidating, which I handle and validate all three cells in. So even though all the cells are valid and none are dirty it will still validate them all. That's a waste. Here's an example of what I have: void dataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { // Ignore cell if it's not dirty if (dataGridView.isCurrentCellDirty) return; // Validate current cell. } void dataGridView_RowValidating(object sender, DataGridViewCellCancelEventArgs e) { // Ignore Row if it's not dirty if (!dataGridView.IsCurrentRowDirty) return; // Validate all cells in the current row. } void dataGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e) { // Validate all cells in the current row and return if any are invalid. // If they are valid, save changes to the database // This is when I would expect dataGridView.IsCurrentRowDirty to be false. // When this row loses focus it will trigger RowValidating and validate all // cells in this row, which we already did above. } I've read posts that said I could call the form's Validate() method, but that will cause RowValidating to fire, which is what I'm trying to avoid. Any idea how I can set DataGridView.IsCurrentRowDirty to true? Or maybe a way to prevent RowValidating from unnecessarily validating all the cells?

• Problem loading Oracle client libraries when running in a NAnt build

  - by Chris Farmer

  I am trying to use dbdeploy to manage Oracle schema changes. I can run it successfully from the command line to get it to generate my change scripts, but when I try to execute it via the dbdeploy NAnt task running through TeamCity, I get an error: System.Data.OracleClient requires Oracle client software version 8.1.7 or greater. I do have the Oracle 10.2.0.2 client software installed. It's the first entry in the system path, and the dbdeploy.exe app is able to successfully negotiate an Oracle connection. The dbdeploy code dynamically loads the System.Data.OracleClient assembly, which in-turn tries to use the Oracle client bits to talk to the database. This is what is failing in my NAnt environment. I have verified the following points: The same user identity is running the process in both cases The same working directory is used in both cases The same dbdeploy code is running in both cases and with the same supplied parameters The same database connection string is being used in both cases The same ADO.NET assembly is being dynamically loaded in both cases (System.Data.OracleClient, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089) Here's the top of the stack trace during the error: at System.Data.OracleClient.OCI.DetermineClientVersion() at System.Data.OracleClient.OracleInternalConnection.OpenOnLocalTransaction (String userName, String password, String serverName, Boolean integratedSecurity, Boolean unicode, Boolean omitOracleConnectionName) at System.Data.OracleClient.OracleInternalConnection..ctor( OracleConnectionString connectionOptions) at System.Data.OracleClient.OracleConnectionFactory.CreateConnection( DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection( DbConnection owningConnection, DbConnectionPool pool, DbConnectionOptions options) at System.Data.ProviderBase.DbConnectionPool.CreateObject( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.GetConnection( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.GetConnection( DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection( DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OracleClient.OracleConnection.Open() at Net.Sf.Dbdeploy.Database.DatabaseSchemaVersionManager. GetCurrentVersionFromDb() My main question is this: how can I discover what's different about these running environments to see why my Oracle client software can't be loaded?

• Orca: extracting files from merge module

  - by Mystagogue

  All I want is a command-line tool that can extract files from a merge module (.msm) onto disk. I looked up Orca (version 3.1), whose documentation states: Many merge module options can be specified from the command line... Extracting Files from a Merge Module Orca supports three different methods for extracting files contained in a merge module. Orca can extract the individual CAB file, extract the files into a module tree and extract the files into a source image once it has been merged into a target database... Extracting Files To extract the individual files from a merge module, use the ... -x ... option on the command line, where is the desired path to the new directory tree. The specified path is used as the root path for the extracted files. All files are extracted from the CAB file embedded in the module and placed in the specified path. The directory layout for the extracted files is based on the directory tree of the merge module. It mostly sounds like exactly what I need. But when I try it, orca simply opens up an editor (with info on the msm I specified) and then does nothing. I've tried a variety of command lines: orca -x theDirectory theModule.msm orca theModule.msm -x theDirectory ...and others. I get nowhere. The closest I've gotten was this: orca -q -x theDirectory -m theModule.msm ...but then it complains that I didn't specifiy a database to merge into. But I'm not trying to merge anything, no less into a database. I just want the files extracted. Can someone explain what I'm doing wrong with the command line options?

• Getting types of the attributes in an ActiveRecord object

  - by Michael Neale

  I would like to know if it is possible to get the types (as known by AR - eg in the migration script and database) programmatically (I know the data exists in there somewhere). For example, I can deal with all the attribute names: ar.attribute_names.each { |name| puts name } .attributes just returns a mapping of the names to their current values (eg no type info if the field isn't set). Some places I have seen it with the type information: in script/console, type the name of an AR entity: >> Driver => Driver(id: integer, name: string, created_at: datetime, updated_at: datetime) So clearly it knows the types. Also, there is .column_for_attribute, which takes an attr name and returns a column object - which has the type buried in the underlying database column object, but it doesn't appear to be a clean way to get it. I would also be interested in if there is a way that is friendly for the new "ActiveModel" that is coming (rails3) and is decoupled from database specifics (but perhaps type info will not be part of it, I can't seem to find out if it is). Thanks.

• Error creating Rails DB using rake db:create

  - by Simon

  Hi- I'm attempting to get my first "hello world" rails example going using the rails' getting started guide on my OSX 10.6.3 box. When I go to execute the first rake db:create command (I'm using mysql) I get: simon@/Users/simon/source/rails/blog/config: rake db:create (in /Users/simon/source/rails/blog) Couldn't create database for {"reconnect"=>false, "encoding"=>"utf8", "username"=>"root", "adapter"=>"mysql", "database"=>"blog_development", "pool"=>5, "password"=>nil, "socket"=>"/opt/local/var/run/mysql5/mysqld.sock"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) I found plenty of stackoverflow questions addressing this problem with the following advice: Verify that user and password are correct (I'm running w/ no password for root on my dev box) Verify that the socket is correct - I can cat the socket, so I assume it's correct Verify that the user can create a DB (As you can see root can connect and create a this DB no problem) simon@/Users/simon/source/rails/blog/config: mysql -uroot -hlocalhost Welcome to the MySQL monitor.

• Rhino Mocks, Dependency Injection, and Separation of Concerns

  - by whatispunk

  I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusinessLogic {} Each exists in a separate assembly. I want to mock MyDataAccess in the tests for MyBusinessLogic. So I added a constructor to the MyBusinessLogic class to take an IMyDataAccess parameter for the dependency injection. But now when I try to create an instance of MyBusinessLogic on the UI layer it requires a reference to the DAL. I thought I could define a default constructor on MyBusinessLogic to set a default IMyDataAccess implementation, but not only does this seem like a codesmell it didn't actually solve the problem. I'd still have a public constructor with IMyDataAccess in the signature. So the UI layer still requires a reference to the DAL in order to compile. One possible solution I am toying with is to create an internal constructor for MyBusinessLogic with the IMyDataAccess parameter. Then I can use an Accessor from the test project to call the constructor. But there's still that smell. What is the common solution here. I must just be doing something wrong. How could I improve the architecture?

• How do you clean Core Data generated models and code from a project?

  - by Hazmit

  I'm having an extremely annoying problem with Core Data in the iPhone SDK. I would say in general Core Data for the most part appears easy to use and nice to implement. I have a sqlite database that is being used as a read only reference to pull data elements out for an iPhone app. It would seem there are really mysterious issues relating to what seems to be migration of the database to the most recent versions of my schema. Why can't you just clean out your stored objects and models and let a project redo all of it when you compile next? You would think if you setup a stored object model there would be a way to just reset it and recompile. I've tried what feels like a thousand 'tips' that have been the results of hours of google searches and documentation prowling to figure out how to do this. My most recent error during compile time is below. 2010-04-07 18:23:51.891 PE[1962:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't merge models with two different entities named 'PElement'' All of this code has been working in the simulator and is only causing me troubles now because I made a change to the schema. I also have the database options for automatically migrating set as below. NSMutableDictionary *optionsDictionary = [NSMutableDictionary dictionary]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption]; [optionsDictionary setObject:[NSNumber numberWithBool:YES] forKey:NSInferMappingModelAutomaticallyOption];

• When to use RDLC over RDL reports?

  - by Daan

  I have been studying SSRS 2005 / 2008 in the past weeks and have created some server side reports. For some application, a colleague suggested that I look into RDLC for that particular situation. I am now trying to get my head around the main difference between RDL and RDLC. Searching for this information yields fragmented information at best. I have learned that: RDLC reports do not store information about how to get data. RDLC reports can be executed directly by the ReportViewer control. But I still don't fully understand the relation between the RDLC file and the other related systems (the Reporting Server, the source database, the client). In order to get a good grasp on RDLC files, I would like to know how their use differs from RDL files and in what situation one would choose RDLC over RDL. Links to resources are also welcome. Update: A thread on the ASP.NET forums discusses this same issue. From it, I have gained some better understanding on the issue. A feature of RDLC is that it can be run completely client-side in the ReportViewer control. This removes the need for a Reporting Services instance, and even removes the need for any database connection whatsoever, but: It adds the requirement that the data that is needed in the report has to be provided manually. Whether this is an advantage or a disadvantage depends on the particular application. In my application, an instance of Reporting Services is available anyway and the required data for the reports can easily be pulled from a database. Is there any reason left for me to consider RDLC, or should I simply stick with RDL?

• "Unable To Load Client Print Control" - SSRS Printing problems again

  - by mamorgan1

  Please forgive me as my head is spinning. I have tried so many solutions to this issue, that I'm almost not sure where I am at this point. At this point in time I have these issues in my Production, Test, and Dev environments. For simplicity sake, I will just try to get it working in Dev first. Here is my setup: Database/Reporting Server (Same server): Windows Server 2003 SP2 SQL Server 2005 SP3 Development Box: Windows 7 Visual Studio 2008 SP1 SQL Server 2008 SP1 (not being used in this case, but wanted to include it in case it is relative) Internet Explorer 8 Details: * I have a custom ASP.NET application that is using ReportViewer to access reports on my Database/Reporting Server. * I am able to connect directly to Report Manager and print with no trouble. * When I view source on the page with ReportViewer, it says I'm am using version 9.0.30729.4402 . * The classid of the rsclientprint.dll that keeps getting installed to my c:\windows\downloaded program files directory is {41861299-EAB2-4DCC-986C-802AE12AC499}. * I have tried taking the rsclientprint.cab file from my Database/Reporting Server and installing it directly to my Development Box and had no success. I made sure to unregister the previously installed dll first. I feel like I have read as many solutions as I can, and so I turn to you for some assistance. Please let me know if I can provide further details that would be helpful. Thanks

• How do I achieve a 'select or insert' task using LINQ to EF?

  - by ProfK

  I have an import process with regions, locations, and shifts, where a Shift object has a Location property, and a Location object has a Region property. If a region name does not exist, I create the region, and like wise a location. I thought I could neatly encapsulate the 'Select if exists, or create' logic into helper classes for Region and Location, but if I use local data contexts in these classes I run into attach and detach overheads that become unpleasent. If I include a data context dependency in these classes, my encapsulation feels broken. What is the ideal method for achieving this, or where is the ideal place to place this functionality? In my example I have leaned heavily on the foreign key crutch provided with .NET 4.0, and simply avoided using entities in favour of direct foreign key values, but this is starting to smell. Example: public partial class ActivationLocation { public static int GetOrCreate(int regionId, string name) { using (var ents = new PvmmsEntities()) { var loc = ents.ActivationLocations.FirstOrDefault(x => x.RegionId == regionId && x.Name == name); if (loc == null) { loc = new ActivationLocation {RegionId = regionId, Name = name}; ents.AddToActivationLocations(loc); ents.SaveChanges(SaveOptions.AcceptAllChangesAfterSave); } return loc.LocationId; } } }
