  • Why am I getting the extra xmlns="" using LinqToXML?

    - by Hcabnettek
    Hello all, I'm using LinqToXML to generate a piece of XML. Everything works great except I'm throwing in some empty namespace declarations somehow. Does anyone out there know what I'm doing incorrectly? Here is my code private string SerializeInventory(IEnumerable<InventoryInformation> inventory) { var zones = inventory.Select(c => new { c.ZoneId , c.ZoneName , c.Direction }).Distinct(); XNamespace ns = "http://www.dummy-tmdd-address"; XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance"; var xml = new XElement(ns + "InventoryList" , new XAttribute(XNamespace.Xmlns + "xsi", xsi) , zones.Select(station => new XElement("StationInventory" , new XElement("station-id", station.ZoneId) , new XElement("station-name", station.ZoneName) , new XElement("station-travel-direction", station.Direction) , new XElement("detector-list" , inventory.Where(p => p.ZoneId == station.ZoneId).Select(plaza => new XElement("detector" , new XElement("detector-id", plaza.PlazaId))))))); xml.Save(@"c:\tmpXml\myXmlDoc.xml"); return xml.ToString(); } And here is the resulting xml. I hope it renders correctly? The browser may hide the tags. - <InventoryList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.dummy-tmdd-address"> <StationInventory xmlns=""> <station-id>999</station-id> <station-name>Zone 999-SEB</station-name> <station-travel-direction>SEB</station-travel-direction> <detector-list> <detector> <detector-id>7503</detector-id> </detector> <detector> <detector-id>2705</detector-id> </detector> </detector-list> </StationInventory> </InventoryList> Notice the empty namespace declaration in the first child element. Any ideas how I can remedy this? Any tips are of course appreciated. Thanks All, ~ck

  • A leader election algorithm for an oriented hypercube

    - by mick
    I'm stuck with some problem where I have to design a leader election algorithm for an oriented hypercube. This should be done by using a tournament with a number of rounds equal to the dimension D of the hypercube. In each stage d, with 1 <= d < D two candidate leaders of neighbouring d-dimensional hypercubes should compete to become the single candidate leader of the (d+1)-dimensional hypercube that is the union of their respective hypercubes.

  • Can a View Controller manage more than 1 nib based view?

    - by Hugo Brynjar
    I have a VC controlling a screen of content that has 2 modes; a normal mode and an edit mode. Can I create a single VC with 2 views, each from separate nibs? In many situations on the iphone, you have a VC which controls an associated view. Then on a button press or other event, a new VC is loaded and its view becomes the top level view etc. But in this situation, I have 2 modes that I want to use the same VC for, because they are closely related. So I want a VC which can swap in/out 2 views. As per here: http://stackoverflow.com/questions/863321/iphone-how-to-load-a-view-using-a-nib-file-created-with-interface-builder/2683153#2683153 I have found that I can load a VC with an associated view from a nib and then later on load a different view from another nib and make that new view the active view. NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"EditMode" owner:self options:nil]; UIView *theEditView = [nibObjects objectAtIndex:0]; self.editView = theEditView; [self.view addSubview:theEditView]; The secondary nib has outlets wired up to the VC like the primary nib. When the new nib is loaded, the outlets are all connected up fine and everything works nicely. Unfortunately when this edit view is then removed, there doesn't seem to be any elegant way of getting the outlets hooked up again to the (normal mode) view from the original nib. Nib loading and outlet setting seems a once only thing. So, if you want to have a VC that swaps in/out 2 views without creating a new VC, what are the options? 1) You can do everything in code, but I want to use nibs because it makes creating the UI simpler. 2) You have 1 nib for your VC and just hide/show elements using the hidden property of UIView and its subclasses. 3) You load a new nib as described above. This is fine for the new nib, but how do you sort the outlets when you go back to the original nib. 4) Give up and accept having a 1:1 between VCs and nibs. There is a nib for normal mode, a nib for edit mode and each mode has a VC that subclasses a common superclass. In the end, I went with 4) and it works, but requires a fair amount of extra work, because I have a model class that I instantiate in normal mode and then have to pass to the edit mode VC because both modes need access to the model. I'm also using NSTimer and have to start and stop the timer in each mode. It is because of all this shared functionality that I wanted a single VC with 2 nibs in the first place.

  • Combining streams on FMS: sync and unify

    - by yn2
    Hi folks, I was wondering if this can be done easily (or at least "can be done"). I have several live streams from different users - all being served by an FMS server for online talk. We are recording every incoming stream. What we want is to join them in some way so we could have a single file, synced, combined from several incoming streams (or recorded flv files). Any ideas?

  • How to 'assign' a value to an output reg in Verilog?

    - by Rafael Almeida
    ( insert really basic question disclaimer here ) More specifically, I have the following declaration: output reg icache_ram_rw And in some point of the code I need to put the zero value in this reg. Here's what I've tried and the outcomes: assign icache_ram_rw = 1'b0; ( declarative lvalue or port sink reg icache_ram_rw must be a wire ) icache_ram_rw <= 1'b0; ( instance gate/name for type "icache_ram_rw" expected - <= read ) How do I do it after all?!

  • Get compiler generated delegate for an event

    - by Sandor Davidhazi
    I need to know what handlers are subsribed to the CollectionChanged event of the ObservableCollection class. The only solution I found would be to use Delegate.GetInvocationList() on the delegate of the event. The problem is, I can't get Reflection to find the compiler generated delegate. AFAIK the delegate has the same name as the event. I used the following piece of code: PropertyInfo notifyCollectionChangedDelegate = collection.GetType().GetProperty("CollectionChanged", BindingFlags.Instance | BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.FlattenHierarchy);

  • WPF DataTemplates with VS2010 designer support + reusable - would you do it that way?

    - by Christian
    Ok, I am currently tidying up all my old stuff. I ran into the issue of "code only DataTemplates" - which are really a pain in the ass. You can't see anything, they are really hard to design, and I want to improve my project. So I had the idea to use the following solution. The main benefits are: You have designer support for your data template You can easily include example sample data The file naming is consistent and easy to remember The preview does not require an additional XAML wrapper (even with code only controls) I will try to explain and illustrate my solution using a few pictures. I am interested in feedback, especially if you can imagine a better way to do it. And, of course, if you see any maintenance or performance issues. Ok, lets start with a simple PreviewObject. I want to have some data in it, so I create a subclass which will automatically fill in some dummy data. Then I add a list to the control, and name this list. Afterwards I add a DataTemplate, this is the sole reason for the whole control (to be able to see and edit the DataTemplate in place): Now I use this control to get my DataTemplate, to use it in other places. To make this easier, I added some code in the code behind, see here: Now I want a control to show me a list of PreviewItems, so I created a "code-only" control which creates an instance of my service (or gets one using DI in real world) and fills its list box with it: To view the result of this work, I added this control inside the same named XAML, this is basically only to be able to see the final result: What I do not like in this solution: The need to create the last control in "code only". So I tried something different while writing this post. The following two screenshots illustrate the approach. I am creating an instance of the service inside the DataContext, and I am using bindings to supply the Itemssourc and the ItemTemplate. The reason for the strange "static property" is refactoring support. If I hardcode the path in the designer (e.g. using "Path = PreviewHistory") and I refactor the names (which happens quite often, early design phase) - I screw up my controls without realizing it. Does anyone has a better idea for this? I am using Resharper, btw. Thanks for any input, and sorry for the image overkill. Just easier to explain that way.. Chris

    In C# .net there is a provision to have two different class files and make them a single class using the keyword partial keyword.this helps it to keep [for ex]UI and logic seperate. of course we can have two classes to achieve this one for UI and other for logic. Can this be achieved in java some how?

  • Correct mapping for SHChangeNotify in JNA

    - by user389658
    This is syntax for SHChangeNotify function from MSDN: void SHChangeNotify( LONG wEventId, UINT uFlags, __in_opt LPCVOID dwItem1, __in_opt LPCVOID dwItem2 ); I've to write its Java counterpart in Java Native Access [JNA], but this declaration seems to be wrong: public interface Shell32 extends com.sun.jna.platform.win32.Shell32 { public Shell32 INSTANCE = (Shell32) Native.loadLibrary(Shell32.class); void SHChangeNotify(long wEventId, int uFlags, Pointer dwItem1, Pointer dwItem2); } I got the following exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'SHChangeNotify' Any idea how to write it correctly?

  • Should Application_End fire on an automatic App Pool Recycle?

    - by Laramie
    I have read this, this, this and this plus a dozen other posts/blogs. I have an ASP.Net app in shared hosting that is frequently recycling. We use NLog and have the following code in global.asax void Application_Start(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION STARTING\r\n\r\n"); } protected void Application_OnEnd(Object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nAPPLICATION_OnEnd\r\n\r\n"); } void Application_End(object sender, EventArgs e) { HttpRuntime runtime = (HttpRuntime)typeof(System.Web.HttpRuntime).InvokeMember("_theRuntime", BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.GetField, null, null, null); if (runtime == null) return; string shutDownMessage = (string)runtime.GetType().InvokeMember("_shutDownMessage", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); string shutDownStack = (string)runtime.GetType().InvokeMember("_shutDownStack", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); ApplicationShutdownReason shutdownReason = System.Web.Hosting.HostingEnvironment.ShutdownReason; NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug(String.Format("\r\n\r\nAPPLICATION END\r\n\r\n_shutDownReason = {2}\r\n\r\n _shutDownMessage = {0}\r\n\r\n_shutDownStack = {1}\r\n\r\n", shutDownMessage, shutDownStack, shutdownReason)); } void Application_Error(object sender, EventArgs e) { NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger(); logger.Debug("\r\n\r\nApplication_Error\r\n\r\n"); } Our log file is littered with "APPLICATION STARTING" entries, but neither Application_OnEnd, Application_End, nor Application_Error are ever fired during these spontaneous restarts. I know they are working because there are entries for touching the web.config or /bin files. We also ran a memory overload test and can trigger an OutOfMemoryException which is caught in Application_Error. We are trying to determine whether the virtual memory limit is causing the recycling. We have added GC.GetTotalMemory(false) throughout the code, but this is for all of .Net, not just our App´s pool, correct? We've also tried var oPerfCounter = new PerformanceCounter(); oPerfCounter.CategoryName = "Process"; oPerfCounter.CounterName = "Virtual Bytes"; oPerfCounter.InstanceName = "iisExpress"; logger.Debug("Virtual Bytes: " + oPerfCounter.RawValue + " bytes"); but don't have permission in shared hosting. I've monitored the app on a dev server with the same requests that caused the recycles in production with ANTS Memory Profiler attached and can't seem to find a culprit. We have also run it with a debugger attached in dev to check for uncaught exceptions in spawned threads that might cause the app to abort. My questions are these: How can I effectively monitor memory usage in shared hosting to tell how much my application is consuming prior to an application recycle? Why are the Application_[End/OnEnd/Error] handlers in global.asax not being called? How else can I determine what is causing these recycles? Thanks.

  • How to use DataContractSerializer to create xml with tag names that match my known types

    - by mezoid
    I have the following data contract: [CollectionDataContract(Name="MyStuff")] public class MyStuff : Collection<object> {} [DataContract(Name = "Type1")] [KnownType(typeof(Type1))] public class Type1 { [DataMember(Name = "memberId")] public int Id { get; set; } } [DataContract(Name = "Type2")] [KnownType(typeof(Type2))] public class Type2 { [DataMember(Name = "memberId")] public int Id { get; set; } } Which I serialize to xml as follows: MyStuff pm = new MyStuff(); Type1 t1 = new Type1 { Id = 111 }; Type2 t2 = new Type2 { Id = 222 }; pm.Add(t1); pm.Add(t2); string xml; StringBuilder serialXML = new StringBuilder(); DataContractSerializer dcSerializer = new DataContractSerializer(typeof(MyStuff)); using (XmlWriter xWriter = XmlWriter.Create(serialXML)) { dcSerializer.WriteObject(xWriter, pm); xWriter.Flush(); xml = serialXML.ToString(); } The resultant xml string looks like this: <?xml version="1.0" encoding="utf-16"?> <MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/"> <anyType i:type="Type1"> <memberId>111</memberId> </anyType> <anyType i:type="Type2"> <memberId>222</memberId> </anyType> </MyStuff> Does anyone know how I can get it to instead use the name of my known types rather than anyType in the xml tag? I'm wanting it to look like this: <?xml version="1.0" encoding="utf-16"?> <MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/"> <Type1> <memberId>111</memberId> </Type1> <Type2> <memberId>222</memberId> </Type2> </MyStuff>

  • will_paginate with named_scopes

    I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.
