  • Localized tables and Entity Framework

    - by Pyttroll
    Hi all, I have a scenario where I need to localized values of objects in my database. Let's say you have an application that can create animals, if the user is english the value of the "Name" property of an animal would be entered as "Cat" in the UI whereas it would be entered as "Chat" in french. The animal culture table would contain 2 records pointing to the same animal in the parent table. When reading values back, if the value of "Name" does not exist in the user culture the default value (value the object was originally created with) would be used. The following diagrams demonstrate how the data is stored in SQL: I'm trying to map this schema to an object model using the Entity Framework, I'm a bit confused as to what the best way to approach the problem. Is EF appropriate for this? Should I used EF4? This EF model will be used by .NET RIA Services. Thanks, Pierre-Yves Troel Ayuda Media Systems http://www.ayudasystems.com

  • ProviderException: InvalidCastException

    - by JS
    Few of our clients are regularly getting invalid cast exception, with variations i.e. InvalidCastException / ProviderException, but both generating from method call: System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) The other variation is: Exception type: InvalidCastException Exception message: Unable to cast object of type System.Int32 to type System.String. I had a look at application event log which shows: Stack trace: at System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) at System.Web.Security.RolePrincipal.IsInRole(String role) at System.Web.Configuration.AuthorizationRule.IsTheUserInAnyRole(StringCollection roles, IPrincipal principal) at System.Web.Configuration.AuthorizationRule.IsUserAllowed(IPrincipal user, String verb) at System.Web.Configuration.AuthorizationRuleCollection.IsUserAllowed(IPrincipal user, String verb) at System.Web.Security.UrlAuthorizationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)* Has anyone come across this issue, and if so what is the fix? Thanks JS

  • Specification: Use cases for CRUD

    - by Mario Ortegón
    I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

  • Is it possible to create ICriteria/ICriterion from LINQ or HQL?

    - by adrin
    I am creating a method that can create filter understood by NHibernate (by filter i mean a set of ICriteria object for example) from my abstract filter object. public static IEnumerable<ICriterion> ToNhCriteria(this MyCriteria criteria) { // T4 generated function // lots of result.Add(Expression.Or(Expression.Eq(),Expression.Eq)) expression trees - hard to generate // Is there a way to generate HQL/Linq query here istead? } then i want to do something like session.CreateCriteria<Entity>().Add(myCriteria.ToNhCriteria()) to filter entities. The problem is that using Expression. methods (Expression.Or etc) is quite tedious (the method is generated and i have multiple or statements that have to be joined into an expression somehow). Is there a way to avoid using Expression.Or() and create ICrietrion / ICriteria using LINQ or HQL?

  • Namespaces and deserialization issue

    - by CaffGeek
    UPDATE: You can run the code at the end of this to recreate and see the error I am having and hopefully solve it! UPDATE2: It's not the removal of the xmlns="" that's the issue... as you can remove it from the initial xml string. The problem is with the [XmlType(TypeName = "Systems")] somehow causing it to be added... UPDATE3: Turns out the problem is in here, I need to set the TypeName based on what is in the existing, XmlTypeAttribute if it already exists on the class.... xmlAttributes.XmlType = new XmlTypeAttribute { Namespace = "" }; I get the following XML as a string from a webservice <Systems xmlns=""> <System id="1"> <sys_name>ALL</sys_name> </System> <System id="2"> <sys_name>asdfasdf</sys_name> </System> <System id="3"> <sys_name>fasdfasf</sys_name> </System> <System id="4"> <sys_name>asdfasdfasdf</sys_name> </System> </Systems> I then execute this, to convert it to an object result = XElement.Parse(xmlResult.OuterXml).Deserialize<AwayRequestSystems>(); Strangely though, in the Deserialize method, while the RemoveAllNamespaces works and returns the xml without the namespace I get the error <Systems xmlns=''> was not expected. in the catch when return (T) serializer.Deserialize(reader); executes!

  • Get All Users in an Active Directory Group

    - by Matt Hanson
    I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group? Private Sub GetUsers() Dim groupSearcher As New DirectorySearcher Dim groupSearchRoot As New DirectoryEntry("LDAP://OU=Users,DC=domain,DC=com") With groupSearcher .SearchRoot = groupSearchRoot .Filter = "(&(ObjectClass=Group)(CN=Domain Users))" End With Dim members As Object members = groupSearcher.FindOne.GetDirectoryEntry.Invoke("Members", Nothing) For Each member As Object In CType(members, IEnumerable) Console.WriteLine(New DirectoryEntry(member).Name.Remove(0, 3)) Next End Sub

  • Why would a error get thrown inside my try-catch?

    - by George Johnston
    I'm pushing a copy of our application over to a new dev server (IIS7) and the application is blowing up on a line inside of a try-catch block. It doesn't happen locally, it actually obey's the rules of a try-catch block, go figure. Any idea why this would be happening? Shouldn't it just be failing silently? Is there something environmental I need to enable/disable? Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Line 229: Try Line 230: Here >> : _MemoryStream.Seek(6 * StartOffset, 0) Line 232: _MemoryStream.Read(_Buffer, 0, 6) Line 233: Catch ex As IOException End Try Although it doesn't matter for answering this question, I thought I would mention that it's third party code for the Geo IP lookup.

  • How to create tests for poco objects

    - by Simon G
    Hi, I'm new to mocking/testing and wanting to know what level should you go to when testing. For example in my code I have the following object: public class RuleViolation { public string ErrorMessage { get; private set; } public string PropertyName { get; private set; } public RuleViolation( string errorMessage ) { ErrorMessage = errorMessage; } public RuleViolation( string errorMessage, string propertyName ) { ErrorMessage = errorMessage; PropertyName = propertyName; } } This is a relatively simple object. So my question is: Does it need a unit test? If it does what do I test and how? Thanks

  • how to get the size of a C global array into an assembly program written for the avr architecture co

    - by johannes
    I have a .c file with the following uint8_t buffer[32] I have a .S file where I want to do the following cpi r29, buffer+sizeof(buffer) The second argument for cpi muste be an imidiate value not a location. But unfortunetly sizeof() is a c operator. Both files, are getting compiled to seperate object files and linked afterwards. If I do avr-objdump -x file.c. Amongst other things, I get the size of the buffer. So it is already available in the object file. How do I access the size of the buffer in my assembly file at compile time?

  • Changing a limited user account in XP fails

    - by javamonkey79
    I have the following: using System; using System.DirectoryServices.AccountManagement; public class ChangePassword { public static void Main() { PrincipalContext context = new PrincipalContext(ContextType.Machine); UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); user.ChangePassword( "xxx", "zzz" ); } } This works just fine with administrator accounts, but seems to crash like so when I try to change limited accounts in XP: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at ChangePassword.Main() Is what I am trying to do possible? If so, how? EDIT #1: I added the following: Console.WriteLine( "user: " + user ); Below this line: UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); And I get this: user: It doesn't look like user is null when I print it, but then again I'm not really a .Net guy - I seem to remember this being expected behavior.

  • iPhone CoreData: How can I track/observe all changes within a subgraph?

    - by D Carney
    I have a NSManagedObjectContext in which I have a number of subclasses of NSManagedObjects such that some are containers for others. What I'd like to do is watch a top-level object to be notified of any changes to any of its properties, associations, or the properties/associations of any of the objects it contains. Using the context's 'hasChanges' doesn't give me enough granularity. The objects 'isUpdated' method only applies to the given object (and not anything in its associations). Is there a convenient (perhaps, KVO-based) was I can observe changes in a context that are limited to a subgraph?

  • NHibernate cascade and inverse

    - by Kordonme
    I have three mappings as follows: public MainChapterMap() { // other properties HasMany(x => x.ClientSpecific).KeyColumn("MainChapterId"); } public MainChapterClientMap() { // other properties References(x => x.MainChapter).Column("MainChapterId"); HasMany(x => x.Details).KeyColumn("MainChapterClientId"); } public MainChapterClientDetailMap() { // other properties References(x => x.MainChapterClient).Column("MainChapterClientId"); } MainChapter has many client-specific chapters. The client-specific chapters (MainChapterClient) has many translations (MainChapterClientDetail) The dele rules should be as follow: When deleting a MainChapter Delete the MainChapterClient row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClient Do NOT delete the MainChapter row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClientDetail Do NOT delete the MainChapter row Do NOT delete the MainChapterClientDetail row(s) But I no matter what I end up getting this error: deleted object would be re-saved by cascade (remove deleted object from associations)[Entities.MainChapterClient#39] I'm not sure how to set up my cascades anymore. Any help are more than welcomed!

    I have strange behaviour with my app after run it on Windows 7. It's connected with NotifyIcon while app is minimized. What should happens: 1) Click once on icon with mouse left button then Balloon with some text should appears 2) Double click on icon will show again app window On Windows 7 MouseDoubleClick is also fired but window is not showing. I don't know why. The same code works good on Windows XP. private void notifyIcon_MouseClick(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { this.NotifyIconShowBalloonWithData(); } } private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e) { this.Show(); WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } What did I wrong? :)

  • I have Person.Surname field implemented as a string if I change the implementation of the field to a

    - by AndyM
    This is me going right back to basics with TDD for learning purposes. I originally implemented Person.Surname as field of type object (the simplest possible way of passing the test. I then added a test setting Person.Surname stating that the return value should be a string and set Person.Surname=20. I 'fixed' the test by changing the implementation to use string rather than object. The test now long compiles due to static type checking, so I commented it out. So I'm left with no way of leaving my intention in the test. Is there a way of having a failing test in this circumstance?

  • Does the WCF framework support the XSD IDREF restriction?

    - by Gerard
    A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

  • When should I use static methods in a class and what are the benefits?

    - by NAVEED
    I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

  • Spring Actionscript: FlexPropertyPlaceholderConfigurer could not be found

    Hi, there! I use springactionscript 1.0RC1 and found an error as following: Error: A class with the name 'org.springextensions.actionscript.ioc.factory.con fig.flex.FlexPropertyPlaceholderConfigurer' could not be found. Are you sure the specified class has been compiled? Look for more information on this topic here: http://www.springactionscript.org/do...inclusion.html and my applicationContext.xml is <objects> <property file="config.properties" required="false" /> <object id="constants" class="com.libsys.utils.Constants"> <property name="endpoint" value="${endpoint}" /> </object> </objects> If the xml file has no properties file, it works fine. I don't know how this happens, could you tell me how to solve it? Thank you! BTW, my compiler version is 4.1.0.14632 and springactionscrip is 1.0RC1.

  • Guidelines of when to use locking

    - by miguel
    I would like to know if there are any guidelineswhich a developer should follow as to when (and where) to place locks. For instance: I understand that code such as this should be locked, to avoid the possibility of another thread changing the value of SomeHeapValue unexpectedly. class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = inputValue_; } } My question is, however, how deep does one go with the locking? For instance, if we have this code: class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = GetSomeHeapValue(); } } Should we lock in the DoSummat(...) method, or should we lock in the GetSomeHeapValue() method? Are there any guidelines that you all keep in mind when strcturing multi-threaded code?
