• detachEvent not working with named anonymous functions

  - by Polshgiant

  I ran into a problem in IE8 today (Note that I only need to support IE) that I can't seem to explain: detachEvent wouldn't work when using a named anonymous function handler. document.getElementById('iframeid').attachEvent("onreadystatechange", function onIframeReadyStateChange() { if (event.srcElement.readyState != "complete") { return; } event.srcElement.detachEvent("onreadystatechange", onIframeReadyStateChange); // code here was running every time my iframe's readyState // changed to "complete" instead of only the first time }); I eventually figured out that changing onIframeReadyStateChange to use arguments.callee (which I normally avoid) instead solved the issue: document.getElementById('iframeid').attachEvent("onreadystatechange", function () { if (event.srcElement.readyState != "complete") { return; } event.srcElement.detachEvent("onreadystatechange", arguments.callee); // code here now runs only once no matter how many times the // iframe's readyState changes to "complete" }); What gives?! Shouldn't the first snippet work fine?

• unable to find an entry point named 'interlockedexchange'

  - by Miki Amit

  Hi , I built an application in c# vs2005 .net . Everything works fine when i run the application in win 32 bit, But when running the application in win 64 it crashes while trying to call the pinvoke interlockedexchange(which is within the kernel32.dll) function . This is the exception : unable to find an entry point named 'interlockedexchange' I didnt find the interlockedexchange function within the kernel32.dll under system32 directory but it was found under the syswow64 directory(in the kernel32.dll) . I guess that the .net runtime is configured to the system32 directory and not to the syswow64 . How is it possible to change this configuration ? Can you think of any other problem that could cause this? any help would be appreciated! thanks , Miki Amit

• WiX ServiceDependency for dynamically named services

  - by glenneroo

  The target system will have a set of dynamically-named CORBA services installed that my own service is dependent on e.g. IT iona_services.config_rep.VirtualXP-37192 cfr-DOMAIN IT iona_services.event.VirtualXP-37192 DOMAIN IT iona_services.ifr.VirtualXP-37192 DOMAIN IT iona_services.locator.VirtualXP-37192 DOMAIN IT iona_services.naming.VirtualXP-37192 DOMAIN IT iona_services.node_daemon.VirtualXP-37192 DOMAIN where "VirtualXP-37192" is the name of the PC. Any ideas what i have to put into this line: <ServiceDependency Id="IT iona_services.*" Group="yes" /> Will i need a custom action thingy to retrieve a list of installed services and search through those? Or is there a way in WiX to retrieve a list of services?

• Named Blueprints with factory_girl

  - by Jason Nerer

  I am using Factory Girl but like the machinist syntax. So I wonder, if there is any way creating a named blueprint for class, so that I can have something like that: User.blueprint(:no_discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader false name "foolish" salt "21746899800.223524289203464" end User.blueprint(:discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader true name "deadbeef" salt "21746899800.223524289203464" discount_rate { DiscountRate.make(:rate => 20.00) } end DiscountRate.blueprint do rate {10} not_before ... not_after ... end Is there a way making factory_girl with machinist syntax acting like that? I did not find one. Help appreciated. Thx in advance Jason

• Replace named group in regex

  - by Tomas Voracek

  I want to use regular expression same way as string.Format. I will explain I have: string pattern = "^(?<PREFIX>abc_)(?<ID>[0-9])+(?<POSTFIX>_def)$"; string input = "abc_123_def"; Regex regex = new Regex(pattern, RegexOptions.IgnoreCase); string replacement = "456"; Console.WriteLine(regex.Replace(input, string.Format("${{PREFIX}}{0}${{POSTFIX}}", replacement))); This works, but i must provide "input" to regex.Replace. I do not want that. I want to use pattern for matching but also for creating strings same way as with string format, replacing named group "ID" with value. Is that possible? I'm looking for something like: string pattern = "^(?<PREFIX>abc_)(?<ID>[0-9])+(?<POSTFIX>_def)$"; string result = ReplaceWithFormat(pattern, "ID", 999); Result will contain "abc_999_def". How to accomplish this?

• RegEx - Indexed\Arrayed Named Capture groups?

  - by Josh

  I have a situation where something can appear in a format as follows: ---id-H-- Header: data Another Header: more data Message: sdasdasdasd Message: asdasdasdasd Message: asdasdasd There may be many messages, or just a couple. I'd prefer not having to step outside of RegEx, because I am using the RegEx to parse some header information above the messages and the messages along with the headers are part of the text I am parsing. The messages attached into the text might be many. I would also like to use named capture groups, so something like Message: (?<Message[index of match]>.+) Where it matches the match as many times as it can with the index filled in. Does anything like this exist in RegEx? (I will eventually be using this in Perl)

• Pass a captured named regular expression to URL dictionary in generic view

  - by Trent Jurewicz

  I am working with a generic view in Django. I want to capture a named group parameter in the URL and pass the value to the URL pattern dictionary. For example, in the URLConf below, I want to capture the parent_slug value in the URL and pass it to the queryset dictionary value like so: urlpatterns = patterns('django.views.generic.list_detail', (r'^(?P<parent_slugs>[-\w])$', 'object_list', {'queryset':Promotion.objects.filter(category=parent_slug)}, 'promo_promotion_list'), ) Is this possible to do in one URLConf entry, or would it be wiser if I create a custom view to capture the value and pass the queryset directly to the generic view from my overridden view?

• Using switch and enumerations as substitute for named methods

  - by MatthewMartin

  This pattern pops up a lot. It looks like a very verbose way to move what would otherwise be separate named methods into a single method and then distinguished by a parameter. Is there any good reason to have this pattern over just having two methods Method1() and Method2() ? The real kicker is that this pattern tends to be invoked only with constants at runtime-- i.e. the arguments are all known before compiling is done. public enum Commands { Method1, Method2 } public void ClientCode() { //Always invoked with constants! Never user input. RunCommands(Commands.Method1); RunCommands(Commands.Method2); } public void RunCommands(Commands currentCommand) { switch (currentCommand) { case Commands.Method1: // Stuff happens break; case Commands.Method2: // Other stuff happens break; default: throw new ArgumentOutOfRangeException("currentCommand"); } }

• I get "stack level too deep" error when using a named scope

  - by Brian Roisentul

  I'm using ruby on rails 2.3.8 and when I write the syntax shown below I get the "stack level too deep" error message. The model is called Announcement and the line of the error looks like this: Tag.find(category_id).announcements.published Where published is named_scope :published, :conditions => "announcements.state = 'published'" I use this named scope in many other places and it works fine. What am I doing wrong? (the relationship between Tag and Announcement model is ok because if I remove the ".published" method from that line it works just fine).

• Deserializing different named xml nodes

  - by Andreas

  Hi. Is there a way to convert different named xml nodes into one class when deserializing an XML Example XML: <items> <aaa>value</aaa> <bbb>value</bbb> </items> Normaly i would write: [XmlRoot("items")] class Items { [XmlElement("aaa")] public string aaa; [XmlElement("bbb")] public string bbb; } But now i would like to do something like this [XmlRoot("items")] class Items { [XmlElement("aaa")] [XmlElement("bbb")] public List<string> item; } Here I would love if "aaa" and "bbb" was added to the same list.

• Are all of the Oracle exceptions named?

  - by John O

  In particular, I've been trying to find the name of the ORA-0955 to improve code readability. Currently I'm using the following: EXCEPTION WHEN OTHERS THEN IF SQLCODE = -00955 What I would prefer is something like: EXCEPTION WHEN OBJECT_EXISTS THEN This seems cleaner to me and I would prefer that. But I've looked in SYS.STANDARD, and it lists relatively few named exceptions. Online documentation seems to mirror what's in SYS.STANDARD. Is there another package to look in? Some other resource?

• Named query not known error trying to call a stored proc using Fluent NHibernate

  - by Hamman359

  I'm working on setting up NHibernate for a project and I have a few queries that, due to their complexity, we will be leaving as stored procedures. I'd like to be able to use NHibernate to call the sprocs, but have run into an error I can't figure out. Since I'm using Fluent NHibernate I'm using mixed mode mapping as recommended here. However, when I run the app I get a "Named query not known: AccountsGetSingle" exception and I can't figure out why. I think I might have a problem with my HBM mapping since I'm not very familiar with using them but I'm not sure. My NHibernate configuration code is: private ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005 .ConnectionString((conn => conn.FromConnectionStringWithKey("CIDB"))) .ShowSql()) .Mappings(m => { m.HbmMappings.AddFromAssemblyOf<Account>(); m.FluentMappings.AddFromAssemblyOf<Account>(); }) .BuildSessionFactory(); } My hbm.xml file is: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="AccountsGetSingle"> <return alias="Account" class="Core, Account"></return> exec AccountsGetSingle </sql-query> </hibernate-mapping> And the code where I am calling the sproc looks like this: public Account Get() { return _conversation.Session .GetNamedQuery("AccountsGetSingle") .UniqueResult<Account>(); } Any thoughts or ideas would be appreciated. Thanks.

• Android & SQLite: "Table audios has no column named downloaded"

  I get this weird exception when i run my app on both the emulator and a USB connected device. i can see the table inside the shell, but when I try to insert a record from the Activity acton I get this exception: android.database.sqlite.SQLiteException: table audios has no column named downloaded I am mostly running on an emulator with Android 1.5. The predominant part of my code is linked to this tutorial - http://www.devx.com/wireless/Article/40842/1954.

• Cocoa App with Python extension which use Scipy -> ImportError: No module named scipy

  - by Snej

  Hi: I have installed Scipy (via macports) for Python on my Mac and it runs fine when running Python scripts. But now I'm using Scipy (via PyObjc) for calculations embedded in a Cocoa App frontend. The following error occurs: ImportError: No module named scipy I am using the "Python.framework" in XCode. Does anybody know why Scipy module is not found? I even added it manually to the module search path via sys.path.append("/opt/local/var/macports/software/py26-scipy/0.7.1_0+gcc43/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/") EDIT: I found the problem myself. The path should be without "/scipy" at the end.

• Using multiple named outlets and a wrapper view with no content in Emberjs

  - by user1889776

  I'm trying to use multiple named outlets with Ember.js. Is my approach below correct? Markup: <script type="text/x-handlebars" data-template-name="application"> <div id="mainArea"> {{outlet main_area}} </div> </script> <script type="text/x-handlebars" data-template-name="home"> <ul id="sections"> {{outlet sections}} </ul> <ul id="categories"> {{outlet categories}} </ul> </script> <script type="text/x-handlebars" data-template-name="sections"> {{#each section in controller}} <li><img {{bindAttr src="section.image"}}></li> {{/each}} </script> <script type="text/x-handlebars" data-template-name="categories"> {{#each category in controller}} <img {{bindAttr src="category.image"}}> {{/each}} </script>? JS Code: Here I set the content of the various controllers to data grabbed from a server and connect outlets with their corresponding views. Since the HomeController has no content, set its content to an empty object - a hack to get the rid of this error message: Uncaught Error: assertion failed: Cannot delegate set('categories' ) to the 'content' property of object proxy : its 'content' is undefined. App.Router = Ember.Router.extend({ enableLogging: false, root: Ember.Route.extend({ index: Ember.Route.extend({ route: '/', connectOutlets: function(router){ router.get('sectionsController').set('content',App.Section.find()); router.get('categoriesController').set('content', App.Category.find()); router.get('applicationController').connectOutlet('main_area', 'home'); router.get('homeController').connectOutlet('home', {}); router.get('homeController').connectOutlet('categories', 'categories'); router.get('homeController').connectOutlet('sections', 'sections'); } }) }) });

• Trouble with Router::url() when using named parameters

  - by sibidiba

  I'm generating plain simple links with CakePHP's HtmlHelper the following way: $html->link("Newest", array( 'controller' => 'posts', 'action' => 'listView', 'page'=> 1, 'sort'=>'Question.created', 'direction'=>'desc', )); Having the following route rule: Router::connect('/foobar/*',array( 'controller' => 'posts', 'action' => 'listView' )); The link is nicely generated as /foobar/page:1/sort:Question.created/direction:desc. Just as I want, it uses my URL prefix instead of controller/action names. However, for some links I must add named parameters like this: $html->link("Newest", array( 'controller' => 'posts', 'action' => 'listView', 'page'=> 1, 'sort'=>'Question.created', 'direction'=>'desc', 'namedParameter' => 'namedParameterValue' )); The link in this case points to /posts/listView/page:1/sort:Question.created/direction:desc/namedParameter:namedParameterValue. But I do not want to have contoller/action names in my URL-s, why is Cake ignoring in this case my routers configuration?

• named type not used for constructor injection

• Named captured substring in pcre++

  - by VDVLeon

  Hello, I want to capture named substring with the pcre++ library. I know the pcre library has the functionality for this, but pcre++ has not implemented this. This is was I have now (just a simple example): pcrepp::Pcre regex("test (?P<groupName>bla)"); if (regex.search("test bla")) { // Get matched group by name int pos = pcre_get_stringnumber( regex.get_pcre(), "groupName" ); if (pos == PCRE_ERROR_NOSUBSTRING) return; // Get match std::string temp = regex[pos - 1]; std::cout << "temp: " << temp << "\n"; } If I debug, pos return 1, and that is right, (?Pbla) is the 1th submatch (0 is the whole match). It should be ok. But... regex.matches() return 0. Why is that :S ? Btw. I do regex[pos - 1] because pcre++ reindexes the result with 0 pointing to the first submatch, so 1. So 1 becomes 0, 2 becomes 1, 3 becomes 2, etc. Does anybody know how to fix this?

• Adding variably named fields to Python classes

  - by Carson Myers

  I have a python class, and I need to add an arbitrary number of arbitrarily long lists to it. The names of the lists I need to add are also arbitrary. For example, in PHP, I would do this: class MyClass { } $c = new MyClass(); $n = "hello" $c.$n = array(1, 2, 3); How do I do this in Python? I'm also wondering if this is a reasonable thing to do. The alternative would be to create a dict of lists in the class, but since the number and size of the lists is arbitrary, I was worried there might be a performance hit from this. If you are wondering what I'm trying to accomplish, I'm writing a super-lightweight script interpreter. The interpreter walks through a human-written list and creates some kind of byte-code. The byte-code of each function will be stored as a list named after the function in an "app" class. I'm curious to hear any other suggestions on how to do this as well.
