  • MS AJAX Library 4.0 Sys.create.dataView

    - by azamsharp
    One again Microsoft poor documentation has left me confused. I am trying to use the new features of the .NET 4.0 framework. I am using the following code to populate the Title and Director but it keeps getting blank. <script language="javascript" type="text/javascript"> Sys.require([Sys.components.dataView, Sys.components.dataContext,Sys.scripts.WebServices], function () { Sys.create.dataView("#moviesView", { dataProvider: "MovieService.svc", fetchOperation: "GetMovies", autoFetch: true }); }); </script> And here it the HTML code: <ul id="moviesView"> <li> {{Title}} - {{Director}} </li> </ul> IS THIS THE LATEST URL TO Start.js file. Here is the Ajax-Enabled WCF Service: [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { [OperationContract] public Movie GetMovies() { return new Movie() { Title = "SS", Director = "SSSSS" }; } } [DataContract] public class Movie { [DataMember] public string Title { get; set; } [DataMember] public string Director { get; set; } }

  • Guaranteed way to find the ildasm.exe and ilasm.exe files regardless of .NET version/environment?

    - by m-y
    Is there a way to programmatically get the FileInfo/Path of the ildasm.exe/ilasm.exe executables? I'm attempting to decompile and recompile a dll/exe file appropriately after making some alterations to it (I'm guessing PostSharp does something similar to alter the IL after the compilation). I found a blog post that pointed to: var pfDir = Environment.GetFolderPath(Environment.SpecialFolders.ProgramFiles)); var sdkDir = Path.Combine(pfDir, @"Microsoft SDKs\Windows\v6.0A\bin"); ... However, when I ran this code the directory did not exist (mainly because my SDK version is 7.1), so on my local machine the correct path is @"Microsoft SDKs\Windows\v7.1\bin". How do I ensure I can actually find the ildasm.exe? Similarly, I found another blog post on how to get access to ilasm.exe as: string windows = Environment.GetFolderPath(Environment.SpecialFolder.System); string fwork = Path.Combine(windows, @"..\Microsoft.NET\Framework\v2.0.50727"); ... While this works, I noticed that I have Framework and Framework64, and within Framework itself I have all of the versions up to v4.0.30319 (same with Framework64). So, how do I know which one to use? Should it be based on the .NET Framework version I'm targetting? Summary: How do I appropriately guarantee to find the correct path to ildasm.exe? How do I appropriately select the correct ilasm.exe to compile?

  • How to sort linq result by most similarity/equality

    - by aNui
    I want to do a search for Music instruments which has its informations Name, Category and Origin as I asked in my post. But now I want to sort/group the result by similarity/equality to the keyword such as. If I have the list { Drum, Grand Piano, Guitar, Guitarrón, Harp, Piano} << sorted by name and if I queried "p" the result should be { Piano, Grand Piano, Harp } but it shows Harp first because of the source list's sequence and if I add {Grand Piano} to the list and query "piano" the result shoud be like { Piano, Grand Piano } or query "guitar" it should be { Guitar, Guitarrón } here's my code static IEnumerable<MInstrument> InstrumentsSearch(IEnumerable<MInstrument> InstrumentsList, string query, MInstrument.Category[] SelectedCategories, MInstrument.Origin[] SelectedOrigins) { var result = InstrumentsList .Where(item => SelectedCategories.Contains(item.category)) .Where(item => SelectedOrigins.Contains(item.origin)) .Where(item => { if ( (" " + item.Name.ToLower()).Contains(" " + query.ToLower()) || item.Name.IndexOf(query) != -1 ) { return true; } return false; } ) .Take(30); return result.ToList<MInstrument>(); } Or the result may be like my old self-invented algorithm that I called "by order of occurence", that is just OK to me. And the further things to do is I need to search the Name, Category or Origin such as. If i type "Italy" it should found Piano or something from Italy. Or if I type "string" it should found Guitar. Is there any way to do those things, please tell me. Thanks in advance.

  • Facebook Graph API - Image Uploading (as3/flash)

    - by lollertits
    I have been trying to get a bit more familiar with the Graph API for facebook. Its very convenient although the documentation is poor at some places. Im having trouble uploading an image to an album. Anyone know how to do it ? This is the code im currently working on :) private function uploadNewPic(albumId:String):void { var bmd1:BitmapData = new BitmapData(200, 200, false, 0x666666); var bm1:Bitmap = new Bitmap(bmd1); var jpgEncoder:JPGEncoder = new JPGEncoder(); var ba:ByteArray = jpgEncoder.encode(bmd1); var data:URLVariables = new URLVariables(); data.message = "Message"; data.image = ba; data.photos = ba; data.url = ba; var method:String = URLRequestMethod.POST; var loader:URLLoader = facebook.call(albumId + "/photos", data, method); loader.addEventListener(FacebookOAuthGraphEvent.ERROR, onPicError); loader.addEventListener(FacebookOAuthGraphEvent.DATA, onPicUploaded); } Im pretty much down to trial and error :) Any ideas ?

  • Jackson object mapping - map incoming JSON field to protected property in base class

    - by Pete
    We use Jersey/Jackson for our REST application. Incoming JSON strings get mapped to the @Entity objects in the backend by Jackson to be persisted. The problem arises from the base class that we use for all entities. It has a protected id property, which we want to exchange via REST as well so that when we send an object that has dependencies, hibernate will automatically fetch these dependencies by their ids. Howevery, Jackson does not access the setter, even if we override it in the subclass to be public. We also tried using @JsonSetter but to no avail. Probably Jackson just looks at the base class and sees ID is not accessible so it skips setting it... @MappedSuperclass public abstract class AbstractPersistable<PK extends Serializable> implements Persistable<PK> { @Id @GeneratedValue(strategy = GenerationType.AUTO) private PK id; public PK getId() { return id; } protected void setId(final PK id) { this.id = id; } Subclasses: public class A extends AbstractPersistable<Long> { private String name; } public class B extends AbstractPersistable<Long> { private A a; private int value; // getter, setter // make base class setter accessible @Override @JsonSetter("id") public void setId(Long id) { super.setId(id); } } Now if there are some As in our database and we want to create a new B via the REST resource: @POST @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) @Transactional public Response create(B b) { if (b.getA().getId() == null) cry(); } with a JSON String like this {"a":{"id":"1","name":"foo"},"value":"123"}. The incoming B will have the A reference but without an ID. Is there any way to tell Jackson to either ignore the base class setter or tell it to use the subclass setter instead? I've just found out about @JsonTypeInfo but I'm not sure this is what I need or how to use it. Thanks for any help!

  • JSON / JSONP in JQuery

    - by dotnetgeek
    Hello. I am trying to figure out why my $.getJSON method does not seem to be working but the $.ajax works just fine. First, here is my getJSON call: $.getJSON("http://localhost:1505/getServiceImageList?callback=loadImagesInSelect", loadImagesInSelect); You can see I have tried added the callback parameter directly to the query string (also tried it not on string) and I added a reference to the callback method defined in my js file. Here is the $.ajax call which works just fine: function getImages() { $.ajax({ type: "GET", url: $('#txt_registry_url').val(), dataType: "jsonp", success:loadImagesInSelect , error:function (xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } In this example the url pulled from the text box is the same as in the straight call to getJSON. When the method call completes, the successMethod is called and everything processes just fine. While I am cool with using the later of the two methods, the docs make it seem that the getJSON is the preferred shorthand way of doing things. Can anyone please explain what I am missing on the shorthand method to make it all work? Thanks in advance.

  • How important is managing memory in Objective-C?

    - by Alex Mcp
    Background: I'm (jumping on the bandwagon and) starting learning about iPhone/iPad development and Objective-C. I have a great background in web development and most of my programming is done in javascript (no libraries), Ruby, and PHP. Question: I'm learning about allocating and releasing memory in Objective-C, and I see it as quite a tricky task to layer on top of actually getting the farking thing to run. I'm trying to get a sense of applications that are out there and what will happen with a poorly memory-managed program. A) Are apps usually released with no memory leaks? Is this a feasible goal, or do people more realistically just excise the worst offenders and that's ok? B) If I make an NSString for a title of a view, let's say, and forget to deallocate it it, does this really only become a problem if I recreate that string repeatedly? I imagine what I'm doing is creating an overhead of the memory needed to store that string, so it's probably quite piddling (a few bytes?) However if I have a rapidly looping cycle in a game that 'leaks' an int every cycle or something, that would overflow the app quite quickly. Are these assumptions correct? Sorry if this isn't up the community-wiki alley, I'm just trying to get a handle on how to think about memory and how careful I'll need to be. Any anecdotes or App Store-submitted app experiences would be awesome to hear as well.

  • Need help with creating PDF from HTML using itextsharp

    - by Steven
    I'm trying to crate a PDF out of a HTML page. The CMS I'm using is EPiServer. This is my code so far: protected void Button1_Click(object sender, EventArgs e) { naaflib.pdfDocument(CurrentPage); } public static void pdfDocument(PageData pd) { //Extract data from Page (pd). string intro = pd["MainIntro"].ToString(); // Attribute string mainBody = pd["MainBody"].ToString(); // Attribute // makae ready HttpContext HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ContentType = "application/pdf"; // Create PDF document Document pdfDocument = new Document(PageSize.A4, 80, 50, 30, 65); //PdfWriter pw = PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); pdfDocument.Open(); pdfDocument.Add(new Paragraph(pd.PageName)); pdfDocument.Add(new Paragraph(intro)); pdfDocument.Add(new Paragraph(mainBody)); pdfDocument.Close(); HttpContext.Current.Response.End(); } This outputs the content of the article name, intro-text and main body. But it does not pars HTML which is in the article text and there is no layout. I've tried having a look at http://itextsharp.sourceforge.net/tutorial/index.html without becomming any wiser. Any pointers to the right direction is greatly appreciated :)

  • ajax error when calling from javascript

    - by vikitor
    Hi, I' still newby to this so I'll try to explain what I'm doing. Basically what I want is to load a dropdownlist depending on the value of a previous one, and I want it to load the data and appear when the other one is changed. This is the code I've written in my controller: public ActionResult GetClassesSearch(bool ajax, string phylumID, string kingdom){ IList<TaxClass> lists = null; int _phylumID = int.Parse(phylumID); int _kingdom = int.Parse(kingdom); lists = _taxon.getClassByPhylumSearch(_phylumID, _kingdom); return Json(lists); } and this is how I call the method from the javascript function: function loadClasses(_phylum) { var phylum = _phylum.value; $.getJSON("/Suspension/GetClassesSearch", { ajax: true, classID: phylum, kingdom: kingdom }, }, function(data) { $('#sClass').attr("disabled", true); $('#sClass').selectOptions("-2"); $('#sClass').removeOption(/./); var values = ''; $('#sClass').addOption("-2", "-Select All-"); for (i = 0; i < data.length; i++) { $('#sClass').addOption(data[i].RecId, data[i].TaxonName); } $('#sClass').selectOptions("-2"); $('#sClass').removeAttr("disabled"); }); } I can't get it to work. Any tips? Thanks in advance

  • How can I make TextToSpeech to speak a text with max volume and restore original volume after speak end?

    - by HelloCW
    I save the current volume both STREAM_RING and STREAM_MUSIC before sTts.get().speak(s, TextToSpeech.QUEUE_ADD, null), I hope the TextToSpeech can speak a text with max volume, but in fact I find the TextToSpeech speak the text with current volume, it seems that sTts.get().speak is asynchronous.

  • Bind to a method in WPF?

    - by Cameron MacFarland
    How do you bind to an objects method in this scenario in WPF? public class RootObject { public string Name { get; } public ObservableCollection<ChildObject> GetChildren() {...} } public class ChildObject { public string Name { get; } } XAML: <TreeView ItemsSource="some list of RootObjects"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type data:RootObject}" ItemsSource="???"> <TextBlock Text="{Binding Path=Name}" /> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type data:ChildObject}"> <TextBlock Text="{Binding Path=Name}" /> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView> Here I want to bind to the GetChildren method on each RootObject of the tree. EDIT Binding to an ObjectDataProvider doesn't seem to work because I'm binding to a list of items, and the ObjectDataProvider needs either a static method, or it creates it's own instance and uses that. For example, using Matt's answer I get: System.Windows.Data Error: 33 : ObjectDataProvider cannot create object; Type='RootObject'; Error='Wrong parameters for constructor.' System.Windows.Data Error: 34 : ObjectDataProvider: Failure trying to invoke method on type; Method='GetChildren'; Type='RootObject'; Error='The specified member cannot be invoked on target.' TargetException:'System.Reflection.TargetException: Non-static method requires a target.

  • Why doesn't my android application show up in the launcher?

    I'm developing an application for the Android platform targeted for api level 4 (Android 1.6) but I can't get it to show up on my phone and I can't figure out why.

  • How to make sure Solr/Lucene won't die with java.lang.OutOfMemoryError?

    - by taw
    I'm really puzzled why it keeps dying with java.lang.OutOfMemoryError during indexing even though it has a few GBs of memory. Is there a fundamental reason why it needs manual tweaking of config files / jvm parameters instead of it just figuring out how much memory is available and limiting itself to that? No other programs except Solr ever have this kind of problem. Yes, I can keep tweaking JVM heap size every time such crashes happen, but this is all so backwards. Here's stack trace of the latest such crash in case it is relevant: SEVERE: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOfRange(Arrays.java:3209) at java.lang.String.<init>(String.java:216) at org.apache.lucene.index.TermBuffer.toTerm(TermBuffer.java:122) at org.apache.lucene.index.SegmentTermEnum.term(SegmentTermEnum.java:169) at org.apache.lucene.search.FieldCacheImpl$StringIndexCache.createValue(FieldCacheImpl.java:701) at org.apache.lucene.search.FieldCacheImpl$Cache.get(FieldCacheImpl.java:208) at org.apache.lucene.search.FieldCacheImpl.getStringIndex(FieldCacheImpl.java:676) at org.apache.lucene.search.FieldComparator$StringOrdValComparator.setNextReader(FieldComparator.java:667) at org.apache.lucene.search.TopFieldCollector$OneComparatorNonScoringCollector.setNextReader(TopFieldCollector.java:94) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:245) at org.apache.lucene.search.Searcher.search(Searcher.java:171) at org.apache.solr.search.SolrIndexSearcher.getDocListNC(SolrIndexSearcher.java:988) at org.apache.solr.search.SolrIndexSearcher.getDocListC(SolrIndexSearcher.java:884) at org.apache.solr.search.SolrIndexSearcher.search(SolrIndexSearcher.java:341) at org.apache.solr.handler.component.QueryComponent.process(QueryComponent.java:182) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:195) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1316) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:338) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:241) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619)

  • Lazy Loading Association and Casting

    - by Zuber
    I am using NHibernate 2.0.1 and .NET I am facing issues with Lazy loading an association I have a BusinessObject class that has associations to other BusinessObject in it, and it can go deeper. The following function is in the BusinessObject to read the values of a collection in the BusinessObject. public virtual object GetFieldValue(string fieldName) { var fieldItems = fieldName.Split(AppConstants.DotChar); var objectToRead = this; for (var i = 0; i < fieldItems.Length - 1; i++) { objectToRead = (BusinessObject) objectToRead.GetFieldValue(fieldItems[i]); } //if (objectToRead._data == null) return objectToRead.SystemId + " Error: _data was null"; return objectToRead.FieldValue(fieldName.LastItem()); } The FieldValue function is described below private object FieldValue(string fieldName) { return _data.Contains(fieldName) ? _data[fieldName] : null; } The BusinessObject has a dictionary_data which stores the field values. Assume the fieldName is BusinessDriver.Description and the BusinessObject which has this field is StrategyBusinessDriver This code breaks down the field name into two - BusinessDriver & Description. The first iteration reads the BusinessDriver object from StrategyBusinessDriver. It is cast into a BusinessObject type so that I can call the GetFieldValue again on it to read the next field i.e Description in the BusinessDriver. The problem is that when I read the BusinessDriver in the first iteration and cast it, I get the Ids and all other details of the BusinessObject but the field dictionary _data and other collections are not fetched. This should be fetched lazily when I read the _data of the BusinessObject. However, this does not happen and I get an error that _data is null. Is there something wrongly coded because of which the collection is not fetched lazily? Please ask for more clarifications if needed. Thanks in advance. UPDATE: It works when I don't do Lazy load.

  • Tracking Down a Stack Overflow in My Linq Query

    - by Lazarus
    I've written the following Linq query: IQueryable<ISOCountry> entries = (from e in competitorRepository.Competitors join c in countries on e.countryID equals c.isoCountryCode where !e.Deleted orderby c.isoCountryCode select new ISOCountry() { isoCountryCode = e.countryID, Name = c.Name }).Distinct(); The objective is to retrieve a list of the countries represented by the competitors found in the system. 'countries' is an array of ISOCountry objects explicitly created and returned as an IQueryable (ISOCountry is an object of just two strings, isoCountryCode and Name). Competitors is an IQueryable which is bound to a database table through Linq2SQL though I created the objects from scratch and used the Linq data mapping decorators. For some reason this query causes a stack overflow when the system tries to execute it. I've no idea why, I've tried trimming the Distinct, returning an anonymous type of the two strings, using 'select c', all result in the overflow. The e.CountryID value is populated from a dropdown that was in itself populated from the IQueryable so I know the values are appropriate but even if not I wouldn't expect a stack overflow. Can anyone explain why the overflow is occurring or give good speculation as to why it might be happening? EDIT As requested, code for ISOCountry: public class ISOCountry { public string isoCountryCode { get; set; } public string Name { get; set; } }

I would like to be able to apply an upSkin to my dynamically generated button like this: //this theSkin variable is dynamic in my app, but for this example it's a simple string var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif"; var navBtn:Button = new Button(); navBtn.id = "thumb1"; navBtn.width = 60; navBtn.height = 45; //skin the button navBtn.setStyle("upSkin", theSkin); //add the button to my canvas myCanvas.addChild(navBtn); When I attempt this, I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class. How do I skin this button with my image dynamically? A couple of things to consider: The upSkin image must be remote. It can't be local. The button must be generated dynamically (it's in a for loop). Any help/ideas would be much appreciated at this point!

  • Haystack / Whoosh Index Generation Error

    - by Keith Fitzgerald
    I'm trying to setup haystack with whoosh backend. When i try to gen the index [or any index command for that matter] i receive: TypeError: Item in ``from list'' not a string if i completely remove my search_indexes.py i get the same error [so i'm guessing it can't find that file at all] what might cause this error? it's set to autodiscover and i'm sure my app is installed because i'm currently using it. Full traceback: Traceback (most recent call last): File "./manage.py", line 17, in <module> execute_manager(settings) File "/Users/ghostrocket/Development/Redux/.dependencies/django/core/management/__init__.py", line 362, in execute_manager utility.execute() File "/Users/ghostrocket/Development/Redux/.dependencies/django/core/management/__init__.py", line 303, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/ghostrocket/Development/Redux/.dependencies/django/core/management/__init__.py", line 257, in fetch_command klass = load_command_class(app_name, subcommand) File "/Users/ghostrocket/Development/Redux/.dependencies/django/core/management/__init__.py", line 67, in load_command_class module = import_module('%s.management.commands.%s' % (app_name, name)) File "/Users/ghostrocket/Development/Redux/.dependencies/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/ghostrocket/Development/Redux/.dependencies/haystack/__init__.py", line 124, in <module> handle_registrations() File "/Users/ghostrocket/Development/Redux/.dependencies/haystack/__init__.py", line 121, in handle_registrations search_sites_conf = __import__(settings.HAYSTACK_SITECONF) File "/Users/ghostrocket/Development/Redux/website/../website/search_sites.py", line 2, in <module> haystack.autodiscover() File "/Users/ghostrocket/Development/Redux/.dependencies/haystack/__init__.py", line 83, in autodiscover app_path = __import__(app, {}, {}, [app.split('.')[-1]]).__path__ TypeError: Item in ``from list'' not a string and here is my search_indexes.py from haystack import indexes from haystack import site from myproject.models import * site.register(myobject)

  • Creating a dynamic linq query

    - by Bas
    I have the following query: from p in dataContext.Repository<IPerson>() join spp1 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp1.PersonId join s1 in dataContext.Repository<ISports>() on spp1.SportsId equals s1.Id join spp2 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp2.PersonId join s2 in dataContext.Repository<ISports>() on spp2.SportsId equals s2.Id where s1.Name == "Soccer" && s2.Name == "Tennis" select new { p.Id }; It selects all the person who play Soccer and Tennis. On runtime the user can select other tags to add to the query, for instance: "Hockey". now my question is, how could I dynamically add "Hockey" to the query? If "Hockey" is added to the query, it would look like this: from p in dataContext.Repository<IPerson>() join spp1 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp1.PersonId join s1 in dataContext.Repository<ISports>() on spp1.SportsId equals s1.Id join spp2 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp2.PersonId join s2 in dataContext.Repository<ISports>() on spp2.SportsId equals s2.Id join spp3 in dataContext.Repository<ISportsPerPerson>() on p.Id equals spp3.PersonId join s3 in dataContext.Repository<ISports>() on spp3.SportsId equals s3.Id where s1.Name == "Soccer" && s2.Name == "Tennis" && s3.Name == "Hockey" select new { p.Id }; It would be preferable if the query is build up dynamically like: private void queryTagBuilder(List<string> tags) { IDataContext dataContext = new LinqToSqlContext(new L2S.DataContext()); foreach(string tag in tags) { //Build the query? } } Anyone has an idea on how to set this up correctly? Thanks in advance!

  • JavaScript types

    - by Alex Ivasyuv
    Hi, as per http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf JavaScript has 6 types: undefined, null, boolean, string, number, object. var und; console.log(typeof und); // <-- undefined var n = null; console.log(typeof n); // <--- **object**! var b = true; console.log(typeof b); // <-- boolean var str = "myString" console.log(typeof str); // <-- string var int = 10; console.log(typeof int); // <-- number var obj = {} console.log(typeof obj); // <-- object Question 1: Why null is object type, if it has to be a null type. Question 2: What about function? var f = function() {}; console.log(typeof f); // <-- function Variable f has "function" type. Why it doesn't specified in specification as separate type. Thanks,

  • Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

    - by ben
    I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

  • Dynamic programming in VB

    - by Rahul Jain
    Hello Everybody, We develop applications for SAP using their SDK. SAP provides a SDK for changing and handling events occuring in the user interface. For example, with this SDK we can catch a click on a button and do something on the click. This programming can be done either VB or C#. This can also be used to create new fields on the pre-existing form. We have developed a specific application which allows users to store the definition required for new field in a database table and the fields are created at the run time. So far, this is good. What we require now is that the user should be able to store the validation code for the field in the database and the same should be executed on the run time. Following is an example of such an event: Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent Dim oForm As SAPbouiCOM.Form If pVal.FormTypeEx = "ACC_QPLAN" Then If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then oProdRec.ItemPressEvent(pVal) End If End If End Sub Public Sub ItemPressEvent(ByRef pVal As SAPbouiCOM.ItemEvent) Dim oForm As SAPbouiCOM.Form oForm = oSuyash.SBO_Application.Forms.GetForm(pVal.FormTypeEx, pVal.FormTypeCount) If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then If pVal.ItemUID = "AC_TXT5" Then Dim CardCode, ItemCode As String ItemCode = oForm.Items.Item("AC_TXT2").Specific.Value CardCode = oForm.Items.Item("AC_TXT0").Specific.Value UpdateQty(oForm, CardCode, ItemCode) End If End If End Sub So, what we need in this case is to store the code given in the ItemPressEvent in a database, and execute this in runtime. I know this is not straight forward thing. But I presume there must be some ways of getting these kind of things done. The SDK is made up of COM components. Thanks & Regards, Rahul Jain
