  • iOS5: Confusion with loadview and init and instance variables

    - by user743550
    I'm new to iOS5 and storyboarding. I noticed that if I declare an instance variables inside my viewcontroller .h file and set the values inside my init of .m file of my viewcontroller, whe the view of the viewcontroller is displayed, my instance variables show null inside viewDidLoad. In order for me to get myvariables, I'd need to do [self init] inside viewDidLoad. My questions are: @interface tableViewController : UITableViewController { NSMutableArray *myvariable; } @end @implementation tableViewController -(id)init { myvariable = [[NSMutableArray alloc]initWithObjects:@"Hi2",@"Yo2",@"whatsup2", nil]; } - (void)viewDidLoad { NSLog(@"%@",myvariable); // DISPLAYS NULL [super viewDidLoad]; } Why isn't my variables available in viewdidLoad when I declared and implemented in my .h and .m files? If that's the case, is viewDidLoad or viewWillAppear the common places to load the data for the viewcontroller? It looks like even if you instantiate a viewcontroller, the init function gets called but the viewDidLoad doesn't necessarily have the variables to be displayed. Where's the right place/methods to load the model(data) for my viewcontroller? Thanks in advance

  • NSXMLParser: how do I wait until loading has finished?

    - by Archagon
    Let's say I'm using NSXMLParser to load a level (stored as an XML document, obviously) into my iPhone game. NSXMLParser works by assigning a delegate and sending it messages at key moments. How do I ensure that my entire level is loaded before doing anything else? I know I can make my main class the delegate and implement parserDidEndDocument, but this feels very hacky. My main class shouldn't have to know anything about the way the parsing is done! On the other hand, if I make a separate class/delegate for parsing my level, my main class has no way of knowing when the parsing is finished, unless it queries the parsing class continuously or the parsing class sends it a message. Either way, the main class would be tied to the implementation of the parsing class. Can I hide all this event-driven business from the main class and simply make the parser return the level object when it's done? (i.e., newLevel = [[GameLevel alloc] initFromXML:xmlfile], which would in turn use NSXMLParser to load the level and then somehow return when finished.) At the moment, I'm using an external DOM parser, but I'm curious how this would be done with NSXMLParser. Sorry if this is a stupid question -- I'm a bit new to this!

  • Using Unit Tests While Developing Static Libraries in Obj-C

    - by macinjosh
    I'm developing a static library in Obj-C for a CocoaTouch project. I've added unit testing to my Xcode project by using the built in OCUnit framework. I can run tests successfully upon building the project and everything looks good. However I'm a little confused about something. Part of what the static library does is to connect to a URL and download the resource there. I constructed a test case that invokes the method that creates a connection and ensures the connection is successful. However when my tests run a connection is never made to my testing web server (where the connection is set to go). It seems my code is not actually being ran when the tests happen? Also, I am doing some NSLog calls in the unit tests and the code they run, but I never see those. I'm new to unit testing so I'm obviously not fully grasping what is going on here. Can anyone help me out here? P.S. By the way these are "Logical Tests" as Apple calls them so they are not linked against the library, instead the implementation files are included in the testing target.

  • Custom RoleProvider: Can't insert record in UsersInRole Table

    - by mahr.g.mohyuddin
    Hi, I have implemented a LINQ to SQL based RoleProvider, when I assign role to a user following exception is thrown while AddUsersToRoles method is called. I have defined a composite primary key userid & roleId on this table, it still throwing this exception: Can't perform Create, Update or Delete operations on 'Table(UsersInRole)' because it has no primary key. My LinQ to SQL implementation of AddUsersToRoles method is as follows. It breaks at db.UsersInRoles.InsertOnSubmit(userInRole); using (RussarmsDataContext db = new RussarmsDataContext()) { List<UsersInRole> usersInRole = new List<UsersInRole>(); foreach (string username in usernames) { foreach (string rolename in rolenames) { UsersInRole userInRole = new UsersInRole(); object userId = ProvidersUtility.GetUserIdByUserName(username,applicationName); object roleId = ProvidersUtility.GetRoleIdByRoleName(rolename,applicationName); if (userId != null && roleId != null) { userInRole.UserId = (Guid)userId; userInRole.RoleId = (Guid)roleId; db.UsersInRoles.InsertOnSubmit(userInRole); } } } try { // db.UsersInRoles.InsertAllOnSubmit(usersInRole); db.SubmitChanges(); } catch (ChangeConflictException) { db.ChangeConflicts.ResolveAll(RefreshMode.OverwriteCurrentValues); db.SubmitChanges(); } } Any help will be appreciated. Thanks.

  • CQRS - The query side

    - by mattcodes
    A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

  • x86 opcode alignment references and guidelines

    - by mrjoltcola
    I'm generating some opcodes dynamically in a JIT compiler and I'm looking for guidelines for opcode alignment. 1) I've read comments that briefly "recommend" alignment by adding nops after calls 2) I've also read about using nop for optimizing sequences for parallelism. 3) I've read that alignment of ops is good for "cache" performance Usually these comments don't give any supporting references. Its one thing to read a blog or a comment that says, "its a good idea to do such and such", but its another to actually write a compiler that implements specific op sequences and realize most material online, especially blogs, are not useful for practical application. So I'm a believer in finding things out myself (disassembly, etc. to see what real world apps do). This is one case where I need some outside info. I notice compilers will usually start an odd byte instruction immediately after whatever previous instruction sequence there was. So the compiler is not taking any special care in most cases. I see "nop" here or there, but usually it seems nop is used sparingly, if at all. How critical is opcode alignment? Can you provide references for cases that I can actually use for implementation? Thanks.

  • Dynamicly set TextBlock's text binding

    - by Mitchell Skurnik
    I am attempting to write a multilingual application in Silverlight 4.0 and I at the point where I can start replacing my static text with dynamic text from a SampleData xaml file. Here is what I have: My Database <SampleData:something xmlns:SampleData="clr-namespace:Expression.Blend.SampleData.MyDatabase" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <SampleData:something.mysystemCollection> <SampleData:mysystem ID="1" English="Menu" German="Menü" French="Menu" Spanish="Menú" Swedish="Meny" Italian="Menu" Dutch="Menu" /> </SampleData:something.mysystemCollection> </SampleData:something> My UserControl <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="Something.MyUC" d:DesignWidth="1000" d:DesignHeight="600"> <Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource MyDatabase}}"> <Grid Height="50" Margin="8,20,8,0" VerticalAlignment="Top" d:DataContext="{Binding mysystemCollection[1]}" x:Name="gTitle"> <TextBlock x:Name="Title" Text="{Binding English}" TextWrapping="Wrap" Foreground="#FF00A33D" TextAlignment="Center" FontSize="22"/> </Grid> </Grid> </UserControl> As you can see, I have 7 languages that I want to deal with. Right now this loads the English version of my text just fine. I have spent the better part of today trying to figure out how to change the binding in my code to swap this out when I needed (lets say when I change the language via drop down). Any help would be great!

  • How to add and remove nested model fields dynamically using Haml and Formtastic

    - by Brightbyte8
    We've all seen the brilliant complex forms railscast where Ryan Bates explains how to dynamically add or remove nested objects within the parent object form using Javascript. Has anyone got any ideas about how these methods need to be modified so as to work with Haml Formtastic? To add some context here's a simplified version of the problem I'm currently facing: # Teacher form (which has nested subject forms) [from my application] - semantic_form_for(@teacher) do |form| - form.inputs do = form.input :first_name = form.input :surname = form.input :city = render 'subject_fields', :form => form = link_to_add_fields "Add Subject", form, :subjects # Individual Subject form partial [from my application] - form.fields_for :subjects do |ff| #subject_field = ff.input :name = ff.input :exam = ff.input :level = ff.hidden_field :_destroy = link_to_remove_fields "Remove Subject", ff # Application Helper (straight from Railscasts) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)} \")")) end #Application.js (straight from Railscasts) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } The problem with implementation seems to be with the javascript methods - the DOM tree of a Formtastic form differs greatly from a regular rails form. I've seen this question asked online a few times but haven't come across an answer yet - now you know that help will be appreciated by more than just me! Jack

  • Getting gridview column value as parameter for javascript function

    - by newName
    I have a gridview with certain number of columns and the ID column where I want to get the value from is currently set to visible = false. The other column is a TemplateField column (LinkButton) and as the user clicks on the button it will grab the value from the ID column and pass the value to one of my javascript function. WebForm: <script language=javascript> function openContent(contentID) { window.open('myContentPage.aspx?contentID=' + contentID , 'View Content','left=300,top=300,toolbar=no,scrollbars=yes,width=1000,height=500'); return false; } </script> <asp:GridView ID="gvCourse" runat="server" AutoGenerateColumns="False" OnRowCommand="gvCourse_RowCommand" OnRowDataBound="gvCourse_RowDataBound" BorderStyle="None" GridLines="None"> <RowStyle BorderStyle="None" /> <Columns> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="lnkContent" runat="server" CommandName="View" CommandArgument='<%#Eval("contentID") %>' Text='<%#Eval("contentName") %>'> </asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="contentID" HeaderText="contentID" ReadOnly="True" SortExpression="contentID" Visible="False" /> <asp:BoundField DataField="ContentName" HeaderText="ContentName" ReadOnly="True" SortExpression="ContentName" Visible="False" /> </Columns> <AlternatingRowStyle BorderStyle="None" /> Code behind: protected void gvCourse_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "View") { intID = Convert.ToInt32(e.CommandArgument); } } protected void gvCourse_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { ((LinkButton)e.Row.FindControl("lnkContent")).Attributes.Add("onclick", "return openContent('" + intID + "');"); } } right not i'm trying to get the intID based on user selected item so when the user clicks on the linkbutton it will open a popup window using javascript and the ID will be used as querystring.

  • Using PHP Gettext Extension vs PHP Arrays in Multilingual Websites?

    - by janoChen
    So far the only 2 good things that I've seen about using gettext instead of arrays is that I don't have to create the "greeting" "sub-array" (or whatever its called). And I don't have to create a folder for the "default language". Are there other pros and cos of using gettext and php arrays for multilingual websites? USING GETTEXT: spanish/messages.po: #: test.php:3 msgid "Hello World!" msgstr "Hola Mundo" index.php: <?php echo _("Hello World!"); ?> index.php?lang=spanish: <?php echo _("Hello World!"); ?> turns to Hola Mundo USING PHP ARRAYS: lang.en.php <?php $lang = array( "greeting" => "Hello World", ); ?> lang.es.php <?php $lang = array( "greeting" => "Hola Mundo", ); ?> index.php: <?php echo $lang['greeting']; ?> greeting turns to Hello World index.php?lang=spanish <?php echo $lang['greeting']; ?> greeting turns to Hola Mundo (I first started with gettext, but it wasn't supported in my shared free hosting Zymic. I didn't want to use Zend_translate, I found it too complicated to my simple task, so I finally ended up using php define, but later on someone told me I should use arrays)

  • Spatial Rotation in Gmod Expression2.

    - by Fascia
    I'm using expression2 to program behavior in Garry's mod (http://wiki.garrysmod.com/?title=Wire_Expression2) Okay so, to set the precedent. In Gmod I have a block and I am at a complete loss of how to get it to rotate around the 3 up, down and right vectors (Which are local. ie; if I pitch it 45 degrees the forward vector is 0.707, 0.707, 0). Essentially, From the 3 vectors I'd like to be able to get local Pitch/Roll/Yaw. By Local Pitch Roll Yaw I mean that they are completely independent of one another allowing true 3d rotation. So for example; if I place my craft so its nose is parallel to the floor the X,Y,Z would be 0,0,0. If I turn it parallel to the floor (World and Local Yaw) 90 degrees it's now 0, 0, 90. If I then pitch it (World Roll, Local Pitch) it 180 degrees it's now 180, 0, 90. I've already explored quaternions however I don't believe I should post my code here as I think I was re-inventing the wheel. I know I didn't explain that well but I believe the problem is pretty generic. Any help anyone could offer is greatly appreciated. Oh, I'd like to avoid gimblelock too. Essentially calculating the rotation around each of the crafts up/forward/right vectors using the up/forward/right vectors. To simply the question a generic implementation rather than one specific to Gmod is absolutely fine.

  • Datetime Format Setting In SSRS

    - by Amit
    We have a requirement where date time values would be passed to the report parameter which is of "String" date type (and not "DateTime"). The report parameter would be a queried one i.e. it would have a list of values in which the passed value should fall in. The strange part is that if the date time value passed to this parameter is passed in this format mm/dd/yyyy hh:mm:ss AM/PM then only it succeeds otherwise a error is displayed (If month/date/hour/minute/second is having a single digit value then we need to pass single digit value to parameter as well). Assuming that the report server picks this format from the "regional settings" in control panel, we tried modifying the date & time formats as yyyy-mm-dd & HH:mm:ss but the outcome was the same. On researching more I found some suggestions specifying to change the language property in the rdl (I was not able to figure out how) but this would not be the solution I am looking for. I also found another topic here but it didn't provide the solution but it didn't provide the solution we are looking for. I need to understand on if this format is controlled by the report server & is it configurable. It would be great if someone can provide some guidance. Thanks.

  • Could CouchDB benefit significantly from the use of BERT instead of JSON?

    - by Victor Rodrigues
    I appreciate a lot CouchDB attempt to use universal web formats in everything it does: RESTFUL HTTP methods in every interaction, JSON objects, javascript code to customize database and documents. CouchDB seems to scale pretty well, but the individual cost to make a request usually makes 'relational' people afraid of. Many small business applications should deal with only one machine and that's all. In this case the scalability talk doesn't say too much, we need more performance per request, or people will not use it. BERT (Binary ERlang Term http://bert-rpc.org/ ) has proven to be a faster and lighter format than JSON and it is native for Erlang, the language in which CouchDB is written. Could we benefit from that, using BERT documents instead of JSON ones? I'm not saying just for retrieving in views, but for everything CouchDB does, including syncing. And, as a consequence of it, use Erlang functions instead of javascript ones. This would modify some original CouchDB principles, because today it is very web oriented. Considering I imagine few people would make their database API public and usually its data is accessed by the users through an application, it would be a good deal to have the ability to configure CouchDB for working faster. HTTP+JSON calls could still be handled by CouchDB, considering an extra cost in these cases because of parsing.

  • (1 2 3 . #<void>)- heapsort

    - by superguay
    Hello everybody: I tried to implement a "pairing heap" with all the regular operations (merge, delete-min etc.), then I've been requested to write a function that would sort a list using my newly constructed heap implementation. Unfortunately it seems that someting goes wrong... Here's the relevant code: (define (heap-merge h1 h2) (cond ((heap-empty? h1) h2) ((heap-empty? h2) h1) (else (let ((min1 (heap-get-min h1)) (min2 (heap-get-min h2))) (if ((heap-get-less h1) min1 min2) (make-pairing-heap (heap-get-less h1) min1 (cons h2 (heap-get-subheaps h1))) (make-pairing-heap (heap-get-less h1) min2 (cons h1 (heap-get-subheaps h2)))))))) (define (heap-insert element h) (heap-merge (make-pairing-heap (heap-get-less h) element '()) h)) (define (heap-delete-min h) (define (merge-in-pairs less? subheaps) (cond ((null? subheaps) (make-heap less?)) ((null? (cdr subheaps)) (car subheaps)) (else (heap-merge (heap-merge (car subheaps) (cadr subheaps)) (merge-in-pairs less? (cddr subheaps)))))) (if (heap-empty? h) (error "expected pairing-heap for first argument, got an empty heap ") (merge-in-pairs (heap-get-less h) (heap-get-subheaps h)))) (define (heapsort l less?) (let aux ((h (accumulate heap-insert (make-heap less?) l))) (if (not (heap-empty? h)) (cons (heap-get-min h) (aux (heap-delete-min h)))))) And these are some selectors that may help you to understand the code: (define (make-pairing-heap less? min subheaps) (cons less? (cons min subheaps))) (define (make-heap less?) (cons less? '())) (define (heap-get-less h) (car h)) (define (heap-empty? h) (if (null? (cdr h)) #t #f)) Now lets get to the problem: When i run 'heapsort' it returns the sorted list with "void", as you can see: (heapsort (list 1 2 3) <) (1 2 3 . #)..HOW CAN I FIX IT? Regards, Superguay

  • Create System.Data.Linq.Table in Code for Testing

    - by S. DePouw
    I have an adapter class for Linq-to-Sql: public interface IAdapter : IDisposable { Table<Data.User> Activities { get; } } Data.User is an object defined by Linq-to-Sql pointing to the User table in persistence. The implementation for this is as follows: public class Adapter : IAdapter { private readonly SecretDataContext _context = new SecretDataContext(); public void Dispose() { _context.Dispose(); } public Table<Data.User> Users { get { return _context.Users; } } } This makes mocking the persistence layer easy in unit testing, as I can just return whatever collection of data I want for Users (Rhino.Mocks): Expect.Call(_adapter.Users).Return(users); The problem is that I cannot create the object 'users' since the constructors are not accessible and the class Table is sealed. One option I tried is to just make IAdapter return IEnumerable or IQueryable, but the problem there is that I then do not have access to the methods ITable provides (e.g. InsertOnSubmit()). Is there a way I can create the fake Table in the unit test scenario so that I may be a happy TDD developer?

  • Encrypt/Decrypt ECB/PKS5/Blowfish between AS3Crypto & Javax.Crypto fails with padding error

    I have a secret key that was sent to me as a file so I can encrypt some xml data using Blowfish. How do I access the key so that I can use it with AS3Crypto? I assume I need to Embed it using the [Embed] meta tag. It's mimeType="application/octet-stream" but I'm not sure if thats right. How do I embed, then reference this file as the secret key? The xmls that I'm encrypting cannot be decrypted on the Java side. Each attempt fails with this exception: javax.crypto.BadPaddingException: Given final block not properly padded.

  • Evaluation of environment variables in command run by Java's Runtime.exec()

    - by Tom Duckering
    Hi, I have a scenarios where I have a Java "agent" that runs on a couple of platforms (specifically Windows, Solaris & AIX). I'd like to factor out the differences in filesystem structure by using environment variables in the command line I execute. As far as I can tell there is no way to get the Runtime.exec() method to resolve/evaluate any environment variables referenced in the command String (or array of Strings). I know that if push comes to shove I can write some code to pre-process the command String(s) and resolve enviroment variables by hand (using getEnv() etc). However I'm wondering if there is a smarter way to do this since I'm sure I'm not the only person wanting to do this and I'm sure there are pitfalls in "knocking up" my own implementation. Your guidance and suggestions are most welcome. edit: I would like to refer to environment variables in the command string using some consistent notation such as $VAR and/or %VAR%. Not fussed which. edit: To be clear I'd like to be able to execute a command such as: perl $SCRIPT_ROOT/somePerlScript.pl args on Windows and Unix hosts using Runtime.exec(). I specify the command in config file that describes a list of jobs to run and it has to be able to work cross platform, hence my thought that an environment variable would be useful to factor out the filesystem differences (/home/username/scripts vs C:\foo\scripts). Hope that helps clarify it. Thanks. Tom

  • Java EE suitablity for a social network using Cassandra datastore ??

    - by Marcos
    We are in the process of making some important technology decisions for a social networking application. We're planning to have Cassandra(a NoSQL database to support efficient data storage). We would be using Hector(a Java client) to interact with Cassandra. 1.) Would Java EE be a good choice over PHP for a social networking application in terms of performance, scalabilty & complexities? 2.) Another possible implementation strategy, Is it suitable to have backend alone in Java and rest in PHP? 3.) What differences(as compared to PHP) it makes in terms of costs at various stages of application development, deployment and maintenance ? 4.) What are the things to keep in mind as we move along with Java development& deployment(as we are relatively new to the Java background) ? 5.) If you could list some major production deployments of similar type(social network) applications in Java. Thank you!

  • Environment variable names with parentheses, like %ProgramFiles(x86)%, in PowerShell?

    - by jwfearn
    How does one get the value of environment variable whose name contains parentheses in a PowerShell script? To complicate matters, some variables names contains parentheses while others have similar names without parenteses. For example (using cmd.exe): C:\>set | find "ProgramFiles" CommonProgramFiles=C:\Program Files\Common Files CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files ProgramFiles=C:\Program Files ProgramFiles(x86)=C:\Program Files (x86) We see that %ProgramFiles% is not the same as %ProgramFiles(x86)%. My PowerShell code is failing in a weird way because it's ignoring the part of the environment variable name after the parentheses. Since this happens to match the name of a different, but existing, environment variable I don't fail, I just get the right value of the wrong variable. Here's a test function in the PowerShell scripting language to illustrate my problem: function Do-Test { $ok = "C:\Program Files (x86)" # note space between 's' and '( $bad = "$Env:ProgramFiles" + "(x86)" # uses %ProgramFiles% $bin32 = "$Env:ProgramFiles(x86)" # LINE 6, I want to use %ProgramFiles(x86)% if ( $bin32 -eq $ok ) { Write-Output "Pass" } elseif ( $bin32 -eq $bad ) { Write-Output "Fail: %ProgramFiles% used instead of %ProgramFiles(x86)%" } else { Write-Output "Fail: some other reason" } } And here's the output: PS> Do-Test Fail: %ProgramFiles% used instead of %ProgramFiles(x86)% Is there a simple change I can make to line 6 above to get the correct value of %ProgramFiles(x86)%? *NOTE: In the text of this post I am using batch file syntax for environment variables as a convenient shorthand. For example %SOME_VARIABLE% means "the value of the environment variable whose name is SOME_VARIABLE". If I knew the properly escaped syntax in PowerShell, I wouldn't need to ask this question.*

  • Unexpected Html.EditorFor behavior in ASP.NET MVC 2

I have this controller: [HandleError] public class HomeController : Controller { [AcceptVerbs(HttpVerbs.Get)] public ActionResult Lister() { string[] values = { "Hello", "world", "!!!" }; return View(values); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Lister(string[] values) { string[] newValues = { "Some", "other", "values" }; return View(newValues); } } And this is my view which is intended to work for both of these: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<string[]>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Lister </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Lister</h2> <% using (Html.BeginForm()) { %> <% foreach (string value in Model) { %> <%= value %><br /> <% } %> <%= Html.EditorForModel() %> <input type="submit" value="Append Dashes" /> <% } %> </asp:Content> And the problem is that when the post back is made from the view, it hits the correct action, but the text boxes still show the original hello world data while the foreach loop outputs the new values. It feels like something in ASP.NET is overriding my model values from updating the text boxes and they are just displaying the same old values. I found this issue while trying to learn EditorFor with an IEnumerable.

  • Can I use boost::make_shared with a private constructor?

    - by Billy ONeal
    Consider the following: class DirectoryIterator; namespace detail { class FileDataProxy; class DirectoryIteratorImpl { friend class DirectoryIterator; friend class FileDataProxy; WIN32_FIND_DATAW currentData; HANDLE hFind; std::wstring root; DirectoryIteratorImpl(); explicit DirectoryIteratorImpl(const std::wstring& pathSpec); void increment(); public: ~DirectoryIteratorImpl() {}; }; class FileDataProxy //Serves as a proxy to the WIN32_FIND_DATA struture inside the iterator. { friend class DirectoryIterator; boost::shared_ptr<DirectoryIteratorImpl> iteratorSource; FileDataProxy(boost::shared_ptr<DirectoryIteratorImpl> parent) : iteratorSource(parent) {}; public: std::wstring GetFolderPath() const { return iteratorSource->root; } }; } class DirectoryIterator : public boost::iterator_facade<DirectoryIterator, detail::FileDataProxy, std::input_iterator_tag> { friend class boost::iterator_core_access; boost::shared_ptr<detail::DirectoryIteratorImpl> impl; void increment() { impl->increment(); }; detail::FileDataProxy dereference() const { return detail::FileDataProxy(impl); }; public: DirectoryIterator() { impl = boost::make_shared<detail::DirectoryIteratorImpl>(); }; }; It seems like DirectoryIterator should be able to call boost::make_shared<DirectoryIteratorImpl>, because it is a friend of DirectoryIteratorImpl. However, this code fails to compile because the constructor for DirectoryIteratorImpl is private. Since this class is an internal implementation detail that clients of DirectoryIterator should never touch, it would be nice if I could keep the constructor private. Is this my fundamental misunderstanding around make_shared or do I need to mark some sort of boost piece as friend in order for the call to compile?

  • Creating a shim Stream

    - by spender
    A decompression API that I am using has the following API: Decode(Stream inStream,Stream outStream) I'd like to create a wrapper around this API, such that I can create my own Stream class which offers up the decoded data. Stream decodedStream=new BlaDecodeStream(inStream); So that I can than use this stream as a parameter to the XmlReader constructor in the same way one might use the System.IO.Compression.GZipStream. As far as I can tell, the only other option is set outStream stream to a MemoryStream or to a FileStream and go in two hops. The files I am dealing with are enormous, so neither of these options are particularly attractive. Before I go reinventing the wheel, is there any prior art that I might be able to draw from, or something in the BCL I might have missed? The CircularStream implementation here would go some of the way to helping, but I'm really looking for something similar that would block (as opposed to over/underrun) when the Stream's internal buffer is 'empty' when reading from it and block when the internal buffer is full when writing to it. In this way it could serve as parameter outStream and simultaneously (i.e. from another thread) could be read from by the XmlReader.

  • Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

    - by user295479
    Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

  • Subview of custom NSView is resizing itself to fit within its superview

    - by Jonathan Patt
    I have a custom NSView which contains a subview—for the purposes of solving this issue, the top level view is simply acting as a container and automatically resizes to fit within the window. Its subview draws a rectangle 10 pixels inset from the edge of the window, except for the bottom, which should get clipped by the window until it's resized to show the entire rectangle. It does not, however, behave as I intend, and instead shrinks the height of the rectangle when its superview has a smaller height than it does. How do I avoid this and have it stay at its proper height and instead get clipped when the superview is smaller? The parent view's implementation code is: - (id)initWithFrame:(NSRect)frameRect { self = [super initWithFrame:frameRect]; if (self) { subView = [[SubView alloc] initWithFrame:frameRect]; } return self; } - (void)drawRect:(NSRect)dirtyRect { [[NSColor grayColor] set]; [subView setFrame:NSMakeRect(10, 10, dirtyRect.size.width - 20, 500)]; [self addSubview:subView]; } - (BOOL)isFlipped { return YES; } And the subview is just: - (void)drawRect:(NSRect)dirtyRect { [[NSColor blackColor] set]; [NSBezierPath strokeRect:dirtyRect]; } - (BOOL)isFlipped { return YES; }
