  • How do I serialize an object to xml but not have it be the root element of the xml document

    - by mezoid
    I have the following object: public class MyClass { public int Id { get; set;} public string Name { get; set; } } I'm wanting to serialize this to the following xml string: <MyClass> <Id>1</Id> <Name>My Name</Name> </MyClass> Unfortunately, when I use the XMLSerializer I get a string which looks like: <?xml version="1.0" encoding="utf-8"?> <MyClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Id>1</Id> <Name>My Name</Name> </MyClass> I'm not wanting MyClass to be the root element the document, rather I'm eventually wanting to add the string with other similar serialized objects which will be within a larger xml document. i.e. Eventually I'll have a xml string which looks like this: <Classes> <MyClass> <Id>1</Id> <Name>My Name</Name> </MyClass> <MyClass> <Id>1</Id> <Name>My Name</Name> </MyClass> </Classes>" My first thought was to create a class as follows: public class Classes { public List<MyClass> MyClasses { get; set; } } ...but that just addes an additional node called MyClasses to wrap the list of MyClass.... My gut feeling is that I'm approaching this the wrong way and that my lack of experience with creating xml files isn't helping to point me to some part of the .NET framework or some other library that simplifies this.

  • Newbie questions about COM

    - by smwikipedia
    Hi, I am quite new to COM so the question may seem naive. Q1. About Windows DLL Based on my understanding, a Windows DLL can export functions, types(classes) and global variables. Is this understanding all right? Q2. About COM My naive understanding is that: a COM DLL seems to be just a new logical way to organize the functions and types exported by a standard Windows DLL. A COM DLL exports both functions such as DllRegisterServer() and DllGetClassObject(), and also the Classes which implements the IUnknown interface. Is this understanding all right? Q3. *.def & *.idl *.def is used to define the functions exported by a Windows DLL in the traditional way, such as DllGetClassObject(). *.idl is used to define the interface implemented by a COM coclass. Thanks in advance.

  • Optimizing if-else /switch-case with string options

    - by cc
    What modification would bring to this piece of code? In the last lines, should I use more if-else structures, instead of "if-if-if" if (action.equals("opt1")) { //something } else { if (action.equals("opt2")) { //something } else { if ((action.equals("opt3")) || (action.equals("opt4"))) { //something } if (action.equals("opt5")) { //something } if (action.equals("opt6")) { //something } } } Later Edit: This is Java. I don't think that switch-case structure will work with Strings. Later Edit 2: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ).

  • Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

    - by Michael Kohout
    Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

  • jQuery plug-in with additional methods.

    - by Kieron
    I've a jQuery plug-in that operates on some ULs, adding and removing classes etc. During the life-cycle of the page, I'll need to add/ remove some classes in code, and as my plug-in needs to perform some additional operations when this happens I came up with the following: // This is the initialiser method... $.fn.objectBuilder = function (options) {...}; // These are the two new methods I need. $.fn.objectBuilder.setSelected(element) {...}; $.fn.objectBuilder.removeSelected() {...}; I'd then like to call them like this: $("#ob1").objectbuilder.removeSelected(); Any thoughts? Thanks, Kieron edit I suppose what I'm asking is, whats the best way of adding additional methods to a jQuery plug-in where it'll have access to the root object, in this case #obj when the method is called.

  • Integration Test Example With Rhino Mocks

    - by guazz
    I have two classes. I would like to verify that the properties are called on one of the classes. public classA { public IBInterface Foo {get;set;} public LoadData() { Foo.Save(1.23456, 1.23456); } } public classB : IBInterface { public decimal ApplePrice {get; set;} public decimal OrangePrice {get; set;} public void Save(decimal param1, decimal param2) { this.ApplePrice = param1; this.OrangePrice = param2; } } I would like to use Rhino Mocks(AAA syntax) to verify that ApplePrice and OrangePrice were set correctly. I assume I should begin like so but how do I verify that ApplePrice and OrangePrice have been set? var mockInterfaceB = mockery.DynamicMock(); ClassA a = new ClassA(); a.Foo = mockInterfaceB; a.LoadData();

  • How to reinforce pseudo css rules

    - by danwoods
    Is there anyway to reinforce pseudo css rules? ie: I have a listing of divs (playlist) which I color with the following rules: #playlist .playlist_item { background: #d6d6d6; } #playlist .playlist_item:nth-child(odd) { background: #b3b3b3; } Now, when a song is playing, I use setInterval and JQuery's .animate function to pulse the background color. When the song is finished I clear the interval, but of course the song's background remains the last color set in the interval. Is there a way to re-set the song's color based on the CSS rule? Otherwise I'll have to keep track of the previous song (which may have changed position, and thus color) or setup distinct background color classes and reset the classes of all the songs in the playlist anytime someone adds, removes, or moves a song in the playlist or a song ends. I'd much rather use a CSS only approach. Thanks in advance, Dan

  • SyndicationItem.Content is Null

    - by kdmurray
    I'm trying to pull the contents of an RSS feed into an object that can be manipulated in code. It looks like the SyndicationFeed and SyndicationItem classes in .NET 3.5 will do what I need, except for one thing. Every time I've tried to read in the contents of an RSS feed using the SyndicationFeed class, the .Content element for each SyndicationItem is null. I've run my feed through FeedValidator and have tried this with feeds from several other sources, but to no avail. XmlReader xr = XmlReader.Create("http://shortordercode.com/feed/"); SyndicationFeed feed = SyndicationFeed.Load(xr); foreach (SyndicationItem item in feed.Items) { Console.WriteLine(item.Title.Text); Console.WriteLine(item.Content.ToString()); } Console.ReadLine(); I suspect I may just be missing a step somewhere, but I can't seem to find a good tutorial on how to consume RSS feeds using these classes.

  • Convert List of one type to Array of another type using Dozer

    - by aheu
    I'm wondering how to convert a List of one type to an array of another type in Java using Dozer. The two types have all the same property names/types. For example, consider these two classes. public class A{ private String test = null; public String getTest(){ return this.test } public void setTest(String test){ this.test = test; } } public class B{ private String test = null; public String getTest(){ return this.test } public void setTest(String test){ this.test = test; } } I've tried this with no luck. List<A> listOfA = getListofAObjects(); Mapper mapper = DozerBeanMapperSingletonWrapper.getInstance(); B[] bs = mapper.map(listOfA, B[].class); I've also tried using the CollectionUtils class. CollectionUtils.convertListToArray(listOfA, B.class) Neither are working for me, can anyone tell me what I am doing wrong? The mapper.map function works fine if I create two wrapper classes, one containing a List and the other a b[]. See below: public class C{ private List<A> items = null; public List<A> getItems(){ return this.items; } public void setItems(List<A> items){ this.items = items; } } public class D{ private B[] items = null; public B[] getItems(){ return this.items; } public void setItems(B[] items){ this.items = items; } } This works oddly enough... List<A> listOfA = getListofAObjects(); C c = new C(); c.setItems(listOfA); Mapper mapper = DozerBeanMapperSingletonWrapper.getInstance(); D d = mapper.map(listOfA, D.class); B[] bs = d.getItems(); How do I do what I want to do without using the wrapper classes (C & D)? There has got to be an easier way... Thanks!

  • Open source iPhone components? Reusable views, controllers, buttons, table cells, etc?

    - by Ian Terrell
    Are there any repositories around for open sourced iPhone components? For instance, I have found myself needing to create several new types of table cells to mimic some of Apple's existing functionality (for instance, all the different types of table cells present in the Settings application). I can't imagine I'm alone here. Where do you go to find open sourced reusable components, or do you just write and hoard your own? Update: I know there are open source full projects around (see this question), but rummaging through them and picking and choosing still leads to significant duplication of effort. Update 2: Here are some libraries that I've found (or have come into existence) since asking this question: Three20 -- Custom UI classes used in the Facebook application CocoaHelpers -- Extensions to common classes MBProgressHUD -- Replacement for the undocumented UIProgressHUD

  • Is there an equivalent to Java's ClassFileTransformer in .NET? (a way to replace a class)

    - by Alix
    I've been searching for this for quite a while with no luck so far. Is there an equivalent to Java's ClassFileTransformer in .NET? Basically, I want to create a class CustomClassFileTransformer (which in Java would implement the interface ClassFileTransformer) that gets called whenever a class is loaded, and is allowed to tweak it and replace it with the tweaked version. I know there are frameworks that do similar things, but I was looking for something more straightforward, like implementing my own ClassFileTransformer. Is it possible? EDIT #1. More details about why I need this: Basically, I have a C# application and I need to monitor the instructions it wants to run in order to detect read or write operations to fields (operations Ldfld and Stfld) and insert some instructions before the read/write takes place. I know how to do this (except for the part where I need to be invoked to replace the class): for every method whose code I want to monitor, I must: Get the method's MethodBody using MethodBase.GetMethodBody() Transform it to byte array with MethodBody.GetILAsByteArray(). The byte[] it returns contains the bytecode. Analyse the bytecode as explained here, possibly inserting new instructions or deleting/modifying existing ones by changing the contents of the array. Create a new method and use the new bytecode to create its body, with MethodBuilder.CreateMethodBody(byte[] il, int count), where il is the array with the bytecode. I put all these tweaked methods in a new class and use the new class to replace the one that was originally going to be loaded. An alternative to replacing classes would be somehow getting notified whenever a method is invoked. Then I'd replace the call to that method with a call to my own tweaked method, which I would tweak only the first time is invoked and then I'd put it in a dictionary for future uses, to reduce overhead (for future calls I'll just look up the method and invoke it; I won't need to analyse the bytecode again). I'm currently investigating ways to do this and LinFu looks pretty interesting, but if there was something like a ClassFileTransformer it would be much simpler: I just rewrite the class, replace it, and let the code run without monitoring anything. An additional note: the classes may be sealed. I want to be able to replace any kind of class, I cannot impose restrictions on their attributes. EDIT #2. Why I need to do this at runtime. I need to monitor everything that is going on so that I can detect every access to data. This applies to the code of library classes as well. However, I cannot know in advance which classes are going to be used, and even if I knew every possible class that may get loaded it would be a huge performance hit to tweak all of them instead of waiting to see whether they actually get invoked or not. POSSIBLE (BUT PRETTY HARDCORE) SOLUTION. In case anyone is interested (and I see the question has been faved, so I guess someone is), this is what I'm looking at right now. Basically I'd have to implement the profiling API and I'll register for the events that I'm interested in, in my case whenever a JIT compilation starts. An extract of the blogpost: In your ICorProfilerCallback2::ModuleLoadFinished callback, you call ICorProfilerInfo2::GetModuleMetadata to get a pointer to a metadata interface on that module. QI for the metadata interface you want. Search MSDN for "IMetaDataImport", and grope through the table of contents to find topics on the metadata interfaces. Once you're in metadata-land, you have access to all the types in the module, including their fields and function prototypes. You may need to parse metadata signatures and this signature parser may be of use to you. In your ICorProfilerCallback2::JITCompilationStarted callback, you may use ICorProfilerInfo2::GetILFunctionBody to inspect the original IL, and ICorProfilerInfo2::GetILFunctionBodyAllocator and then ICorProfilerInfo2::SetILFunctionBody to replace that IL with your own. The great news: I get notified when a JIT compilation starts and I can replace the bytecode right there, without having to worry about replacing the class, etc. The not-so-great news: you cannot invoke managed code from the API's callback methods, which makes sense but means I'm on my own parsing the IL code, etc, as opposed to be able to use Cecil, which would've been a breeze. I don't think there's a simpler way to do this without using AOP frameworks (such as PostSharp). If anyone has any other idea please let me know. I'm not marking the question as answered yet.

  • Strategy Design Pattern -- *dynamic* !!!

    - by alexeypro
    My application will have different strategies for my objects. What's the best way of implementing that? I would really love the case when we can make strategy classes implementation dynamically loaded from, say, some relational database. Not sure how do that better, though. What's the best approach? Idea is that say we want to apply to object MyObj strategy Strategy123 then we just load from database by ID 123 the object, deserialize it, get the Strategy class, and use it with MyObj. The maintenance while sounds easier from the first look can be a pain in the long run if Strategy interfaces changes, etc. What can I do also? I want to find solution when I should be keeping Strategy classes in codebase -- just for the sake that I don't need code change and re-deployment of the application if my Strategy changes, or I add new strategy. Please advise!

  • Does an IFilter Exist for Indexing Source Code Files?

    - by AMissico
    Anybody know of an IFilter that can index source code files beyond what the "Plain Text" filter can provide, with possibly a custom "Property Set" specific to programming? For example, I have 835MB in 41,000 files and 8,200 folders in my "Code Library" folder. I would like to perform searches such as "select distinct attributes on properties" or "select class exceptions" or "select classes with nested private classes". Preferrably, the IFilter can distinguish between various languages, so I can perform a query like "select class exceptions in VB.NET" or "select 'resume next' in VBScript". Other Examples "select all enum from folder('microsoft source code') in namespace 'system.io'"

  • CSS selectors : should I make my CSS easier to read or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It make my .css file harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • Why don't these class attributes register?

    - by slypete
    I have a factory method that generates django form classes like so: def get_indicator_form(indicator, patient): class IndicatorForm(forms.Form): #These don't work! indicator_id = forms.IntegerField(initial=indicator.id, widget=forms.HiddenInput()) patient_id = forms.IntegerField(initial=patient.id, widget=forms.HiddenInput()) def __init__(self, *args, **kwargs): forms.Form.__init__(self, *args, **kwargs) self.indicator = indicator self.patient = patient #These do! setattr(IndicatorForm, 'indicator_id', forms.IntegerField(initial=indicator.id, widget=forms.HiddenInput())) setattr(IndicatorForm, 'patient_id', forms.IntegerField(initial=patient.id, widget=forms.HiddenInput())) for field in indicator.indicatorfield_set.all(): setattr(IndicatorForm, field.name, copy(field.get_field_type())) return type('IndicatorForm', (forms.Form,), dict(IndicatorForm.__dict__)) I'm trying to understand why the top form field declarations don't work, but the setattr method below does work. I'm fairly new to python, so I suspect it's some language feature that I'm misunderstanding. Can you help me understand why the field declarations at the top of the class don't add the fields to the class? In a possibly related note, when these classes are instantiated, instance.media returns nothing even though some fields have widgets with associated media. Thanks, Pete

  • Python language API

    - by Oscar Reyes
    Hello. I'm starting with Python coming from java. I was wondering if there exists something similar to JavaDoc API where I can find the class, its methods and and example of how to use it. I've found very helpul to use help( thing ) from the Python ( command line ) I have found this also: http://docs.python.org/ http://docs.python.org/modindex.html But it seems to help when you already the class name you are looking for. In JavaDoc API I have all the classes so if I need something I scroll down to a class that "sounds like" what I need. Or some times I just browse all the classes to see what they do, and when I need a feature my brain recalls me We saw something similar in the javadoc remember!? But I don't seem to find the similar in Python ( yet ) and that why I'm posting this questin. BTW I know that I would eventually will read this: http://docs.python.org/lib/lib.html But, well, I think it is not today.

  • compiling actionscript from command line using MXMLC

    - by I. J. Kennedy
    I have a tiny actionscript "project" consisting of two files, call them foo.as and bar.as. For reasons I won't go into, I really really want to build the .SWF from the command line, without setting up a formal project of any kind. Every compiler I've ever used lets you do this, but for the life of me I can't figure out how to coerce MXMLC into compiling these two files and linking them into a SWF. Naively, I try MXMLC foo.as bar.as but I'm informed that only one source file is allowed. Ok, supposing I compiled these two files separately, how would I link them together to get the final SWF? NOTE: The only reason I have two files instead of one is the requirement of only one class per file. I tried putting both classes in one file and making one of the classes "private" or "internal" but neither of these ideas worked. I would be ecstatic to find out I can put more than one class in a file (with only one being public).

  • Create javadoc with multiple src dirs

    - by Ed Marty
    I have a Util package with source files in three seperate directories, defined like so: src/com/domain/util src/Standard/com/domain/util src/Extended/com/domain/util The package is built with the first set of files and either one of the second or third set, to create a total of two different implementations of the same interface. Now, I want to generate javadoc based on those files. How can I specify that? What I really want to do is javadoc com.domain.util -sourcepath ./src;./src/Standard to build the javadoc for the standard util package, and javadoc com.domain.util -sourcepath ./src;./src/Extended to build the javadoc for the extended util package. This doesn't work. The only way I've found so far to actually make it work is to merge the directory structure of the common classes and the Standard classes into another location and run with that for the standard javadoc, then do the same for the Extended package. Is there another way?

  • Modifying CollectionEditor in PropertyGrid

    - by Chris
    I currently have a list containing Call's, which is the base class. If I want to add derived classes of Call to the list, I know to do the following. public class CustomCollectionEditor : System.ComponentModel.Design.CollectionEditor { private Type[] types; public CustomCollectionEditor(Type type) : base(type) { types = new Type[] { typeof(Call), typeof(CappedCall) }; } protected override Type[] CreateNewItemTypes() { return types; } } public class DisplayList { public DisplayList() { } [Editor(typeof(CustomCollectionEditor), typeof(UITypeEditor))] [DataMember] public List<Call> ListCalls { get; set; } } My questions is there anyway of moving where you mark up the Type[] containing all possible types the list can contain? I thought of adding the following to my CustomCollectionEditor class, but this doesn't work. public CustomCollectionEditor(Type type, List<Type> types_) : base(type) { types = types_.ToArray(); } It would be ideal if I could mark up which classes the CustomCollectionEditor needed to be aware of in the DisplayList class somehow.

  • WEB-INF/lib jars not found in JBoss 4.0.2 war deploy

  • Memory Profiling: How to detect which application/package is consuming too much memory

    - by malvim
    Hi, I have a situation here at work where we run a JEE server with several applications deployed on it. Lately, we've been having frequent OutOfMemoryException's. We suspect some of the apps might be behaving badly, maybe leaking, or something. The problem is, we can't really tell which one. We have run some memory profilers (like YourKit), and they're pretty good at telling what classes use the most memory. But they don't show relationships between classes, so that leaves us with a situation like this: We see that there are, say, lots of Strings and int arrays and HashMap entries, but we can't really tell which application or package they come from. Is there a way of knowing where these objects come from, so we can try to pinpoint the packages (or apps) that are allocating the most memory? Thank you in advance.
