• Integrate Zend translator into my app

  - by clinisbut

  Hello. I wish to use the Translator classes of Zend framework in my app, but I don't want to include the whole framework. I grabbed the: Locale folder Translate folder Exception.php Loader.php Locale.php Registry.php Translate.php and copied into a custom folder named zend.translator. Obviously I had to edit all them to adjust the includes to the new path... Is this the way to go? I'm worried to have to edit all those files every time a new version is released.

• Odd "Object reference not set to an instance of an object" involving xWinForms

  - by Kyle

  Hey, I've been trying to get the xWinForms 3.0 library (a library with forms support in xna) working with my C# XNA Game project but I keep getting the same problem. I add the reference to my project, put in the using statement, declare a formCollection variable and then I try to initialize it. whenever I run the project I get stopped on this line: formCollection = new FormCollection(this.Window, Services, ref graphics); it gives me the error: " System.NullReferenceException was unhandled Message="Object reference not set to an instance of an object."

• C# Linq Entity Conversion Error on Nonexistent Value?

  - by Ryan

  While trying to query some data using the Linq Entity Framework I'm receiving the following exception: {"Conversion failed when converting the varchar value '3208,7' to data type int."} The thing that is confusing is that this value does not even exist in the view I am querying from. It does exist in the table the view is based on, however. The query I'm running is the following: return context.vb_audit_department .Where(x => x.department_id == department_id && x.version_id == version_id) .GroupBy(x => new { x.action_date, x.change_type, x.user_ntid, x.label }) .Select(x => new { action_date = x.Key.action_date, change_type = x.Key.change_type, user_ntid = x.Key.user_ntid, label = x.Key.label, count = x.Count(), items = x }) .OrderByDescending(x => x.action_date) .Skip(startRowIndex) .Take(maximumRows) .ToList(); Can somebody explain why LINQ queries the underlying table instead of the actual view, and if there is any way around this behavior?

• How do I fix this JBoss EJB client authentication issue?

  - by Rich

  I have an EJB deployed under JBoss (we're moving a project to it from Weblogic), I can get an EJBHome reference to the EJB via a JNDI lookup. The login-config.xml is set to use the module org.jboss.security.auth.spi.BaseCertLoginModule. When my client code tries to invoke the create method via reflection, calling invoke, I get an InvocationException which wraps an AccessException, which wraps a final exception of javax.security.auth.login.FailedLoginException: Password Incorrect/Password Required at org.jboss.security.auth.spi.UsernamePasswordLoginModule.login(UsernamePasswordLoginModule.java:213).... Am I missing some client code to use BaseCertLoginModule instead of UsernamePasswordLoginModule? Thanks in advance, any suggestions appreciated, apologies for not posting the entire stacktrace but it's on a secured network without internet access.

• Activator.CreateInstance(Type) for a type without parameterless constructor

  - by Seb

  Reading existing code at work, I wondered how come this could work. I have a class defined in an assembly : [Serializable] public class A { private readonly string _name; private A(string name) { _name = name; } } And in another assembly : public void f(Type t) { object o = Activator.CreateInstance(t); } and that simple call f(typeof(A)) I expected an exception about the lack of a parameterless constructor because AFAIK, if a ctor is declared, the compiler isn't supposed to generate the default public parameterless constructor. This code runs under .NET 2.0.

• Server.Transfer("error_404.aspx") in Application_Error returns a blank page

  - by qntmfred

  I look for HttpExceptions in the Application_Error sub of my global.asx Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs) Dim ex As Exception = HttpContext.Current.Server.GetLastError() If ex IsNot Nothing Then If TypeOf (ex) Is HttpUnhandledException Then If ex.InnerException Is Nothing Then Server.Transfer("error.aspx", False) End If ex = ex.InnerException End If If TypeOf (ex) Is HttpException Then Dim httpCode As Integer = CType(ex, HttpException).GetHttpCode() If httpCode = 404 Then Server.ClearError() Server.Transfer("error_404.aspx", False) End If End If End If End Sub I can step through this code and confirm it does hit the Server.Transfer("error_404.aspx"), as well as the Page_Load of error_404.aspx, but all it shows is a blank page.

• How to implement List, Set, and Map in null free design?

  - by Pyrolistical

  Its great when you can return a null/empty object in most cases to avoid nulls, but what about Collection like objects? In Java, Map returns null if key in get(key) is not found in the map. The best way I can think of to avoid nulls in this situation is to return an Entry<T> object, which is either the EmptyEntry<T>, or contains the value T. Sure we avoid the null, but now you can have a class cast exception if you don't check if its an EmptyEntry<T>. Is there a better way to avoid nulls in Map's get(K)? And for argument sake, let's say this language don't even have null, so don't say just use nulls.

• SQLServer Binary Data with ActiveRecord and JDBC

  - by John Duff

  I'm using the activerecord-jdbc-adapter with ActiveRecord to be able to access a SQLServer database for Rails Application running under jRuby and am having trouble inserting binary data. The Exception I am getting is below. Note I just have a blurb for the binary data from the fixtures that was working fine for MySQL. ActiveRecord::StatementInvalid: ActiveRecord::ActiveRecordError: Operand type clash: nvarchar is incompatible with image: INSERT INTO blobstorage_datachunks ([id], [datafile_id], [chunk_number], [data]) VALUES (369397133, 663419003, 0, N'GIF89a@') When I created the tables the migration had binary and SQLServer used Image instead. We're using Rails 2.3.5, SQLServer Express 2008. What I'm looking for is a way to get the binary data into SQLServer with ActiveRecord. Thanks in advance for the help.

• Facebook canvas app ASP.NET MVC HttpException: Invalid Model

  - by zznq

  I am working on a Facebook tab application. I am using asp.net MVC 2 with the "official" Microsoft Facebook SDK. Most of my views are working just fine. However, I have one that is causing a huge mess. I am simply returning a List<Tags> to the view and as my ViewModel. This problematic view is simply displaying the list in a foreach loop. Whenever navigate to this view I get a "System.Web.HttpException: Invalid Model" exception. The most puzzling part of all this is that the same code is running without fail on our regular(non-Facebook) app that works just fine with the same code. Any insight into why Facebook and asp.net MVC 2 would be causing this behavior would be much appreciated.

• MVC2: "File not found" after view is painted

  - by Dave Hanna

  This is wierd. First, I'm building a site based on someone else's framework (Piers Lawson: Creating a RESTful Web Service using MVC ), so I'm not entirely sure what's going on under the covers. But when I run it in VS 2010 by pressing F5, it brings up the Home page, and THEN traps an error in Application_Error. The error is "File does not exist" exception. But I have no idea what file it's looking for. Where does flow control go after the View is finished displaying? How can I break to find out what it's looking for?

• SAXException: Unexpected end of file after null

  - by itsadok

  I'm getting the error in the title occasionally from a process the parses lots of XML files. The files themselves seem OK, and running the process again on the same files that generated the error works just fine. The exception occurs on a call to XMLReader.parse(InputStream is) Could this be a bug in the parser (I use piccolo)? Or is it something about how I open the file stream? No multithreading is involved. Piccolo seemed like a good idea at the time, but I don't really have a good excuse for using it. I will to try to switch to the default SAX parser and see if that helps. Update: It didn't help, and I found that Piccolo is considerably faster for some of the workloads, so I went back.

• Why can you reference an imported module using the importing module in python

  - by noam

  I am trying to understand why any import can be referenced using the importing module, e.g #module master.py import slave and then >>>import master >>>print master.slave gives <module 'slave' from 'C:\Documents and Settings....'> What is the purpose of the feature? I can see how it can be helpful in a package's __init__.py file, but nothing else. Is it a side effect of the fact that every import is added to the module's namespace and that the module's namespace is visible from the outside? If so, why didn't they make an exception with data imported from other modules (e.g don't show it as part of the module's namespace for other modules)?

• Regular expression replace in PL/pgSQL

  - by dreamlax

  If I have the following input (excluding quotes): "The ancestral territorial imperatives of the trumpeter swan" How can I collapse all multiple spaces to a single space so that the input is transformed to: "The ancestral territorial imperatives of the trumpeter swan" This is going to be used in a trigger function on insert/update (which already trims leading/trailing spaces). Currently, it raises an exception if the input contains multiple adjacent spaces, but I would rather it simply transforms it into something valid before inserting. What is the best approach? I can't seem to find a regular-expression replace function for PL/pgSQL. There is a text_replace function, but this will only collapse at most two spaces down to one (meaning three consecutive spaces will collapse to two). Calling this function over and over is not ideal.

• Exec Maven Plugin to Command Line

  I have an application developed in NetBeans/Maven that can be started via command line with: mvn exec:exec "-Dexec.executable=C:\\Java\\jdk1.6.0_33\\bin\\java.exe" "-Dexec.args=-Dlog4j.properties=... -classpath %classpath com.xxx.MyLauncher" -Dexec.classpathScope=runtime -Dexec.workingdir= Now I need to run the application through the standard java command line method, like: java -Dlog4j.properties=... -jar myapp-1.2-SNAPSHOT.jar Unfortunately this does not work in the same manner, as I get the following exception: opencard.core.util.OpenCardPropertyLoadingException: property file not found Questions: What is the difference between launching applications with the Exec-Maven-plugin and the standard java execution on command line? Is there an easy way to convert a Maven execution script to a standard command line? How to run the application succesfully?

• Java ServerSocket Multiple Listen Instances

  - by ikurtz

  i have a java game app that uses sockets to communicate with each other. the issue is when i do a socket listen (server), i can run another instance of the game on the same machine using the same port as before to listen, and it results in listening again. now i have two instances of the application both listening on the same port. you can imagine only one connects when a connection comes through. the question is: how do i prevent the app from listening on the same port as another instance is already listening to? thanks in advance. EDIT: serverSocket = new ServerSocket(serverPort, backlog); im using this. should i try to use: ServerSocket(int port, int backlog, InetAddress bindAddr) instead? EDIT: SOLVED! i did not handle the exception only trapped it. now it is working well. thanks for your inputs.

• How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?

  - by Mark Lindell

  I'm using VS1010RC with the POCO self tracking T4 templates. In my WCF update service method I am using something similar to the following: using (var context = new MyContext()) { context.MyObjects.ApplyChanges(myObject); context.SaveChanges(); } This works fine until I set ConcurrencyMode=Fixed on the entity and then I get an exception. It appears as if the context does not know about the previous values as the SQL statement is using the changed entities value in the WHERE clause. What is the correct approach when using ConcurrencyMode=Fixed?

• System.DirectoryServices.AccountManagement not working on the server

  - by mlsteeves

  I am using System.DirectoryServices.AccountManagement to find the logged-in user's AD entry. It is working great in the VS2008 WebDev server on developers machines. But when we installed the code on the development server (windows server 2008), we get an access error. Both the developer's machine and the development server are members of the same domain. We have Impersonation turned on, so we are connecting to AD with the same user credentials. What are we missing here? Why is it working on the developer's machine, but not the development server? The actual exception that we were receiving was "An operations error occurred".

• cast across classloader?

  - by IttayD

  How can I do this: class Foo { public static Foo get() throws Exception { ClassLoader cl = new URLClassLoader(new URL[]{"foo.jar"}, null); // Foo.class is in foo.jar return (Foo)cl.loadClass("Foo").newInstance(); // fails on class cast } } What I need is for the JVM to consider the Foo instance from cl as if it is an instance of Foo from the classloader of the executing code. I have seen these approaches, none of them good for me (the above example is a toy example): Load the class (or a separate interface) by a class loader that is a parent of both the calling code and created classloader Serialize and deserialize the object.
