• update columns when value is numeric in tsql

  - by knittl

  i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

• Configuring Warden for use in RSpec controller specs

  - by Chris Peters

  I was able to use Devise's sign_in method to log in a user in my controller specs. But now that I'm removing Devise from my application, I'm not quite sure how to get similar functionality working with just Warden on its own. How should I go about setting up spec/spec_helper.rb and related spec/support/*.rb files to get Warden running within controller specs sufficiently? I've tried setting up a file at spec/support/warden.rb with these contents: RSpec.configure do |config| config.include Warden::Test::Helpers config.after do Warden.test_reset! end end Then I have before calls similar to this to authenticate a user factory: before { login_as FactoryGirl.create(:user) } But here is the error that I keep seeing: NameError: undefined method `user' for nil:NilClass This error traces back to my authenticate_user! method in the controller: def authenticate_user! redirect_to login_path, notice: "You need to sign in or sign up before continuing." if env['warden'].user.nil? end I'd appreciate any guidance that anyone could provide.

• Using Windows header files within Netbeans 6.8

  - by Matthieu Steffens

  I'm trying to make an windows application within Netbeans. When using Visual studio it is no problem to use files like tchar.h I have receaved a basic file structure containing those and I'm trying to get them to work on Netbeans IDE but it seems that Netbeans won't allow using files from Visual Studio.

But netbenas can't find the tchar.h file while being in same folder...

• C++ Memory Allocation & Linked List Implementation

  - by pws5068

  I'm writing software to simulate the "first-fit" memory allocation schema. Basically, I allocate a large X megabyte chunk of memory and subdivide it into blocks when chunks are requested according to the schema. I'm using a linked list called "node" as a header for each block of memory (so that we can find the next block without tediously looping through every address value. head_ptr = (char*) malloc(total_size + sizeof(node)); if(head_ptr == NULL) return -1; // Malloc Error .. :-( node* head_node = new node; // Build block header head_node->next = NULL; head_node->previous = NULL; // Header points to next block (which doesn't exist yet) memset(head_ptr,head_node, sizeof(node)); ` But this last line returns: error: invalid conversion from 'node*' to 'int' I understand why this is invalid.. but how can I place my node into the pointer location of my newly allocated memory?

• Is it possible to use flashvars with JBoss?

  - by Aikanaro

  Hi, I'm part of a team developing a product using JSF 2.0 and I was asked to investigate the possibility of including FusionCharts free in the app. I have tried different ways of inserting a simple chart in a JSF page but with no luck. On of the methods involves using the elements OBJECT and EMBED but hhen I try to use them I get a "null source" error from JBoss. From what I could find online (through Google), I am under the impression that 'flashvars' isn't quite compatible with JBoss. Is anyone here able to confirm this? If this is the case, what workaround would you suggest me? Other ways I also found online didn't show the chart not even an error message. Thanks in advance.

• Cheapest way of binding local variable to closure

  - by mmotorny

  I believe following to be a cheapest way of binding local variable to closure: void ByRValueReference(A&& a) { } std::function<void ()> CreateClosureByRValueReference() { A a; std::function<void ()> f = std::bind(&ByRValueReference, std::move(a)); // !!! return f; } However, it does not compile under Clang 3.1: error: no viable conversion from '__bind<void (*)(A &&), A>' to 'std::function<void ()>' and gcc 4.6.1: /usr/include/c++/4.6/functional:1778:2: error: no match for call to ‘(std::_Bind<void (*(A))(A&&)>) ()’ Am I violating the standard or it's just broken standard libraries?

• Can't Use Generic C# Class in Using Statement

  - by Eric J.

  I'm trying to use a generic class in a using statement but the compiler can't seem to treat it as implementing IDisposable. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data.Objects; namespace Sandbox { public sealed class UnitOfWorkScope<T> where T : ObjectContext, IDisposable, new() { public void Dispose() { } } public class MyObjectContext : ObjectContext, IDisposable { public MyObjectContext() : base("DummyConnectionString") { } #region IDisposable Members void IDisposable.Dispose() { throw new NotImplementedException(); } #endregion } public class Consumer { public void DoSomething() { using (new UnitOfWorkScope<MyObjectContext>()) { } } } } Compiler error is: Error 1 'Sandbox.UnitOfWorkScope<Sandbox.MyObjectContext>': type used in a using statement must be implicitly convertible to 'System.IDisposable' I implemented IDisposable on UnitOfWorkScope (and to see if that was the problem, also on MyObjectContext). What am I missing?

• jquery ajax vs browser url

  - by danwoods

  Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

• undefined reference

  - by rantravee

  Hi, I'm unfamiliar to working in c++ under linux so I have some issues, one of them is that after I write a class and try to instantiate an object of that class I get to following error : "undefined reference to Constructor_of_that_class" . This happens for every class that I write , and it happens no matter where I try to do the instantiating, even if the code compiles without any problems . What is going wrong here and what I have to do to get over this error ? Because the project that I'm working wasn't created by me I suspect that it has to do something with some settings but I don't know which.

• Difference in DocumentBuilder.parse when using JRE 1.5 and JDK 1.6

  - by dhiller

  Recently at last we have switched our projects to Java 1.6. When executing the tests I found out that using 1.6 a SAXParseException is not thrown which has been thrown using 1.5. Below is my test code to demonstrate the problem. import java.io.StringReader; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.stream.StreamSource; import javax.xml.validation.SchemaFactory; import org.junit.Test; import org.xml.sax.InputSource; import org.xml.sax.SAXParseException; /** * Test class to demonstrate the difference between JDK 1.5 to JDK 1.6. * * Seen on Linux: * * <pre> * #java version "1.6.0_18" * Java(TM) SE Runtime Environment (build 1.6.0_18-b07) * Java HotSpot(TM) Server VM (build 16.0-b13, mixed mode) * </pre> * * Seen on OSX: * * <pre> * java version "1.6.0_17" * Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025) * Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode) * </pre> * * @author dhiller (creator) * @author $Author$ (last editor) * @version $Revision$ * @since 12.03.2010 11:32:31 */ public class TestXMLValidation { /** * Tests the schema validation of an XML against a simple schema. * * @throws Exception * Falls ein Fehler auftritt * @throws junit.framework.AssertionFailedError * Falls eine Unit-Test-Pruefung fehlschlaegt */ @Test(expected = SAXParseException.class) public void testValidate() throws Exception { final StreamSource schema = new StreamSource( new StringReader( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" + "<xs:schema xmlns:xs=\"http://www.w3.org/2001/XMLSchema\" " + "elementFormDefault=\"qualified\" xmlns:xsd=\"undefined\">" + "<xs:element name=\"Test\"/>" + "</xs:schema>" ) ); final String xml = "<Test42/>"; final DocumentBuilderFactory newFactory = DocumentBuilderFactory.newInstance(); newFactory.setSchema( SchemaFactory.newInstance( "http://www.w3.org/2001/XMLSchema" ).newSchema( schema ) ); final DocumentBuilder documentBuilder = newFactory.newDocumentBuilder(); documentBuilder.parse( new InputSource( new StringReader( xml ) ) ); } } When using a JVM 1.5 the test passes, on 1.6 it fails with "Expected exception SAXParseException". The Javadoc of the DocumentBuilderFactory.setSchema(Schema) Method says: When errors are found by the validator, the parser is responsible to report them to the user-specified ErrorHandler (or if the error handler is not set, ignore them or throw them), just like any other errors found by the parser itself. In other words, if the user-specified ErrorHandler is set, it must receive those errors, and if not, they must be treated according to the implementation specific default error handling rules. The Javadoc of the DocumentBuilder.parse(InputSource) method says: BTW: I tried setting an error handler via setErrorHandler, but there still is no exception. Now my question: What has changed to 1.6 that prevents the schema validation to throw a SAXParseException? Is it related to the schema or to the xml that I tried to parse?

• Why does SQL Server keep throwing exceptions?

  - by Augusto Càzares

  I have my project in .NET that uses a database in SQL Server. I'm using Linq-to-SQL, sometimes when the project throws me an exception (Constraint) in a part of the project this same error keeps showing in other part of the project when I do another thing with the database. Like when I do an insertion and I had before an exception on delete the insertion throws me the delete exception, and it remains this way until I close and open again the project. My major problem is when this happen in my online project, this error in my project causes me problems in the project I'm testing online (I use the same database). I don't know if this exception is on the memory or something but its have been causing me a lot of headaches.
