  • How is counting sort a stable sort?

    - by eSKay
    Suppose my input is (a,b and c to distinguish between equal keys) 1 6a 8 3 6b 0 6c 4 My counting sort will save as (discarding the a,b and c info!!) 0(1) 1(1) 3(1) 4(1) 6(3) 8(1) which will give me the result 0 1 3 4 6 6 6 8 So, how is this stable sort? I am not sure how it is "maintaining the relative order of records with equal keys." Please explain.

  • Flash - Firefox issue

    - by Manish
    I realised that if I do have a flash object and do not include a 'wmode' attribute, I will not be able to overlay HTML because the flash will always play on top. But if I do include a 'wmode:transparent' , the flash object completely disappears in firefox, whereas if I use 'wmode:opaque' , I get a white box in place of the Flash object. I've looked at many forums - many questions - but somehow everyone's problem gets resolved when they use one of the aforementioned attributes. So....HELP !!! Note: using either attribute works in IE.

  • Objective-C and sqlite's DATETIME type.

    - by sant0sk1
    I have a sqlite3 table that I'm trying to map to an object in objective-C. One attribute of the table is 'completed_at' which is stored as a DATETIME. I want to create a property on my objective-C class (which inherits from NSObject) that will map well to the 'completed_at' attribute. Objective-C has an NSDate type but I'm not sure if that will map directly?

  • Unbind Key Presses

    - by Doug
    I'm making a game that involves, like all games, key presses. Only left and right arrow and the Space Bar. They work, but the browser is pre-set to scroll left, right, or jump down on those keys. Is there any way to unbind those keys in the code? Thanks.

    - by Inge Henriksen
    I want to do some processing on a attribute before returning the view. If I set the appModel.Markup returned in the HttpPost ActionResult method below to "modified" it still says "original" on the form. Why cant I modify my attribute in a HttpGet ActionResult method? [HttpGet] public ActionResult Index() { return View(new MyModel { Markup = "original" }); } [HttpPost] public ActionResult Index(MyModel appModel) { return View(new MyModel { Markup = "modified" }); }

  • How to print a specific actionerror message with Struts2 validation?

    - by FarmBoy
    When using Struts2 validation, when you put the <s:actionerror> tag in your JSP, the default behavior is to display all the action errors at that point in the page. Is there a way to display only specific error messages at that point? For example, in the case of fielderror one only needs to add the fieldName attribute. Is there an attribute of actionerror that accomplishes similar behavior?

  • Nominal Attributes in LibSVM

    - by Chris S
    When creating a libsvm training file, how do you differentiate between a nominal attribute verses a numeric attribute? I'm trying to encode certain nominal attributes as integers, but I want to ensure libsvm doesn't misinterpret them as numeric values. Unfortunately, libsvm's site seems to have very little documentation. Pentaho's docs seem to imply libsvm makes this distinction, but I'm still not clear how it's made.

  • NameClaimType in ClaimsIdentity from SAML

    - by object88
    I am attempting to understand the world of WIF in context of a WCF Data Service / REST / OData server. I have a hacked up version of SelfSTS that is running inside a unit test project. When the unit tests start, it kicks off a WCF service, which generates my SAML token. This is the SAML token being generated: <saml:Assertion MajorVersion="1" MinorVersion="1" ... > <saml:Conditions>...</saml:Conditions> <saml:AttributeStatement> <saml:Subject> <saml:NameIdentifier Format="EMAIL">4bd406bf-0cf0-4dc4-8e49-57336a479ad2</saml:NameIdentifier> <saml:SubjectConfirmation>...</saml:SubjectConfirmation> </saml:Subject> <saml:Attribute AttributeName="emailaddress" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>[email protected]</saml:AttributeValue> </saml:Attribute> <saml:Attribute AttributeName="name" AttributeNamespace="http://schemas.xmlsoap.org/ws/2005/05/identity/claims"> <saml:AttributeValue>bob</saml:AttributeValue> </saml:Attribute> </saml:AttributeStatement> <ds:Signature>...</ds:Signature> </saml:Assertion> (I know the Format of my NameIdentifier isn't really EMAIL, this is something I haven't gotten to cleaning up yet.) Inside my actual server, I put some code borrowed from Pablo Cabraro / Cibrax. This code seems to run A-OK, although I confess that I don't understand what's happening. I note that later in my code, when I need to check my identity, Thread.CurrentPrincipal.Identity is an instance of Microsoft.IdentityModel.Claims.ClaimsIdentity, which has a claim for all the attributes, plus a nameidentifier claim with the value in my NameIdentifier element in saml:Subject. It also has a property NameClaimType, which points to "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name". It would make more sense if NameClaimType mapped to nameidentifier, wouldn't it? How do I make that happen? Or am I expecting the wrong thing of the name claim? Thanks!

  • Javassist annoations problem

    - by Ali
    I'm trying to generate my Entity class using javassist. Everything went well until I added the GeneratedValue annotation to the Id field. The @Id annotation works fine but when I add @GeneeratedValue I get an exception. This is my code: ClassPool cp = ClassPool.getDefault(); CtClass ctClass = cp.makeClass("test.Snake"); ClassFile classFile = ctClass.getClassFile(); classFile.setVersionToJava5(); AnnotationsAttribute attribute = new AnnotationsAttribute(classFile.getConstPool(), AnnotationsAttribute.visibleTag); Annotation idAnnotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.Id")); attribute.addAnnotation(idAnnotation); Annotation gvAnnotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.GeneratedValue")); attribute.addAnnotation(gvAnnotation); CtField idField = new CtField(ClassPool.getDefault().get("java.lang.Long"), "id", ctClass); idField.getFieldInfo().addAttribute(attribute); ctClass.addField(idField); CtField nameField = new CtField(ClassPool.getDefault().get("java.lang.String"), "name", ctClass); ctClass.addField(nameField); AnnotationsAttribute attr = new AnnotationsAttribute(classFile.getConstPool(), AnnotationsAttribute.visibleTag); Annotation annotation = new Annotation(classFile.getConstPool(), ClassPool.getDefault().get("javax.persistence.Entity")); attr.addAnnotation(annotation); classFile.addAttribute(attr); snakeClass = ctClass.toClass(); newInstance = snakeClass.newInstance(); And this is the exception I get: java.lang.NullPointerException at javassist.bytecode.ConstPool.getUtf8Info(ConstPool.java:565) at javassist.bytecode.annotation.EnumMemberValue.getValue(EnumMemberValue.java:98) at javassist.bytecode.annotation.EnumMemberValue.write(EnumMemberValue.java:116) at javassist.bytecode.annotation.Annotation.write(Annotation.java:316) at javassist.bytecode.AnnotationsAttribute.setAnnotations(AnnotationsAttribute.java:246) at javassist.bytecode.AnnotationsAttribute.addAnnotation(AnnotationsAttribute.java:211) at ClassLoadingTest.javassitTest(ClassLoadingTest.java:56) It seems to be a problem with @GeneratedValue. When I use it alone whithout id I get this exception either. When I use eclipse debugger to watch variable values, I get get this com.sun.jdi.InvocationException occurred invoking method. instead of the annotation value. but for Id annotation it shows a javassist annotation object. I'm new to javassist. Can anyone help me?

  • Dynamic DateTimeRangeValidator using Enterprise Library 4.1?

    - by Toran Billups
    I'm trying to add a range of - 365 days and + 365 days but it appears that using this attribute in EL 4.1 only accepts a special ISO formatted string ... thus I can't simply add a normal string to this validation routine. <DateTimeRangeValidator(DateTime.Now.AddDays(2), DateTime.Now.AddDays(4))> _ I wanted to do something similar to the above - fyi Does anyone know how you can force this attribute to accept this ISO formatted string w/out hand coding this value?

  • C# integer primary key generation using Entity Framework with local database file (Sdf)

    - by Ronny
    Hello, I'm writing a standalone application and I thought using Entity Framework to store my data. At the moment the application is small so I can use a local database file to get started. The thing is that the local database file doesn't have the ability to auto generate integer primary keys as SQL Server does. Any suggestions how to manage primary keys for entities in a local database file that will be compatible with SQL Server in the future? Thanks, Ronny

  • Robust LINQ to XML query for sibling key-value pairs

    - by awshepard
    (First post, please be gentle!) I am just learning about LINQ to XML in all its glory and frailty, trying to hack it to do what I want to do: Given an XML file like this - <list> <!-- random data, keys, values, etc.--> <key>FIRST_WANTED_KEY</key> <value>FIRST_WANTED_VALUE</value> <key>SECOND_WANTED_KEY</key> <value>SECOND_WANTED_VALUE</value> <!-- wanted because it's first --> <key>SECOND_WANTED_KEY</key> <value>UNWANTED_VALUE</value> <!-- not wanted because it's second --> <!-- nonexistent <key>THIRD_WANTED_KEY</key> --> <!-- nonexistent <value>THIRD_WANTED_VALUE</value> --> <!-- more stuff--> </list> I want to extract the values of a set of known "wanted keys" in a robust fashion, i.e. if SECOND_WANTED_KEY appears twice, I only want SECOND_WANTED_VALUE, not UNWANTED_VALUE. Additionally, THIRD_WANTED_KEY may or may not appear, so the query should be able to handle that as well. I can assume that FIRST_WANTED_KEY will appear before other keys, but can't assume anything about the order of the other keys - if a key appears twice, its values aren't important, I only want the first one. An anonymous data type consisting of strings is fine. My attempt has centered around something along these lines: var z = from y in x.Descendants() where y.Value == "FIRST_WANTED_KEY" select new { first_wanted_value = ((XElement)y.NextNode).Value, //... } My question is what should that ... be? I've tried, for instance, (ugly, I know) second_wanted_value = ((XElement)y.ElementsAfterSelf() .Where(w => w.Value=="SECOND_WANTED_KEY") .FirstOrDefault().NextNode).Value which should hopefully allow the key to be anywhere, or non-existent, but that hasn't worked out, since .NextNode on a null XElement doesn't seem to work. I've also tried to add in a .Select(t => { if (t==null) return new XElement("SECOND_WANTED_KEY",""); else return t; }) clause in after the where, but that hasn't worked either. I'm open to suggestions, (constructive) criticism, links, references, or suggestions of phrases to Google for, etc. I've done a fair share of Googling and checking around S.O., so any help would be appreciated. Thanks!
