  • yahoo's attribute exchange -> blank data is coming

    - by Gaurav Sharma
    Hello everybody, I am trying to build openid login system for my website. To do this I used JanRain's php openid library v 2.1.3. I am also using openid selector to select the openid provider from the list. I first created the attributes array that I need to fetch from the provider as follows: $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/contact/email',2,1, 'email'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/first',1,1, 'firstname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/last',1,1, 'lastname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson',1,1, 'fullname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/friendly',1,1, 'username'); $ax = new Auth_OpenID_AX_FetchRequest; foreach($attribute as $attr) { $ax-add($attr); } $auth_request-addExtension($ax); and in the finish_auth.php file I wrote this to fetch the attributes returned $ax = new Auth_OpenID_AX_FetchResponse(); $obj = $ax-fromSuccessResponse($response); Google gives me all the attributes requested but yahoo doesn't (as stated here that yahoo now supports attribute exchange). Is there any limitation set by yahoo on attribute exchange too. (they give limited websites access to sreg extension of openid). :( Please help me, I am stuck over here. Thanks

  • Textually diffing JSON

    - by Richard Levasseur
    As part of my release processes, I have to compare some JSON configuration data used by my application. As a first attempt, I just pretty-printed the JSON and diff'ed them (using kdiff3 or just diff). As that data has grown, however, kdiff3 confuses different parts in the output, making additions look like giant modifies, odd deletions, etc. It makes it really hard to figure out what is different. I've tried other diff tools, too (meld, kompare, diff, a few others), but they all have the same problem. Despite my best efforts, I can't seem to format the JSON in a way that the diff tools can understand. Example data: [ { "name": "date", "type": "date", "nullable": true, "state": "enabled" }, { "name": "owner", "type": "string", "nullable": false, "state": "enabled", } ...lots more... ] The above probably wouldn't cause the problem (the problem occurs when there begin to be hundreds of lines), but thats the gist of what is being compared. Thats just a sample; the full objects are 4-5 attributes, and some attributes have 4-5 attributes in them. The attribute names are pretty uniform, but their values pretty varied. In general, it seems like all the diff tools confuse the closing "}" with the next objects closing "}". I can't seem to break them of this habit. I've tried adding whitespace, changing indentation, and adding some "BEGIN" and "END" strings before and after the respective objects, but the tool still get confused.

  • ASP.NET SQLMembership Provider not logging in

    - by cfdev9
    My web app uses the sql memebership provider. Running it locally all is well, deploying to a dev server it works fine too in firefox, but in IE8 something unexpected is happening. Once a user logs in they're supposed to be redirected to home.aspx. What's happening when I attempt to login is it appears to accept the login credentials but then doesn't redirect to home.aspx. Instead it just redirects me to the login page as though I had attempted to access home.aspx directly without being logged in. The url parameter ReturnUrl is appended, Login.aspx?ReturnUrl=%2fhome.aspx Why is this only happening with IE8? My local PC is IIS7 but the server is IIS6. Using the same web.config Full code behind public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Session.Abandon(); FormsAuthentication.SignOut(); } } protected void btnSubmit_Click(object sender, EventArgs e) { if (Membership.ValidateUser(tbUsername.Text, tbPassword.Text)) { if (Request.QueryString["ReturnUrl"] != null) { FormsAuthentication.RedirectFromLoginPage(tbUsername.Text, false); } else { FormsAuthentication.SetAuthCookie(tbUsername.Text, false); Response.Redirect("~/Home.aspx"); } } } } Full web.config

  • SO what RDF database do i use for product attribute situation initially i thought about using EAV?

    - by keisimone
    Hi, i have a similar issue as espoused in http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters i am convinced to use RDF now. only because of one of the comments made by Bill Karwin in the answer to the above issue but i already have a database in mysql and the code is in php. 1) So what RDF database should I use? 2) do i combine the approach? meaning i have a class table inheritance in the mysql database and just the weird product attributes in the RDF? I dont think i should move everything to a RDF database since it is only just products and the wide array of possible attributes and value that is giving me the problem. 3) what php resources, articles should i look at that will help me better in the creation of this? 4) more articles or resources that helps me to better understand RDF in the context of the above challenge of building something that will better hold all sorts of products' attributes and values will be greatly appreciated. i tend to work better when i have a conceptual understanding of what is going on. Do bear in mind i am a complete novice to this and my knowledge of programming and database is average at best.

  • Does Android XML Layout's 'include' Tag Really Work?

    - by Eric Burke
    I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)" Since Romain indicates this works in the test suites and his examples, I must be doing something wrong. My project is organized like this: res/layout buttons.xml res/layout-land receipt.xml res/layout-port receipt.xml The buttons.xml contains something like this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <Button .../> <Button .../> </LinearLayout> And the portrait and landscape receipt.xml files look something like: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> ... <!-- Overridden attributes never work. Nor do attributes like the red background, which is specified here. --> <include android:id="@+id/buttons_override" android:background="#ff0000" android:layout_width="fill_parent" layout="@layout/buttons"/> </LinearLayout> What am I missing?

  • Really simple JSON serialization in .NET

    - by Evgeny
    I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

  • django class with an array of "parent" foreignkeys issue

    - by user298032
    Let's say I have a class called Fruit with child classes of the different kinds of Fruit with their own specific attributes, and I want to collect them in a FruitBasket: class Fruit(models.Model):     type = models.CharField(max_length=120,default='banana',choices=FRUIT_TYPES)     ... class Banana(Fruit):     """banana (fruit type)"""     length = models.IntegerField(blank=True, null=True)     ... class Orange(Fruit):     """orange (fruit type)"""     diameter = models.IntegerField(blank=True, null=True)     ... class FruitBasket(models.Model):     fruits = models.ManyToManyField(Fruit)     ... The problem I seem to be having is when I retrieve and inspect the Fruits in a FruitBasket, I only retrieve the Fruit base class and can't get at the Fruit child class attributes. I think I understand what is happening--when the array is retrieved from the database, the only fields that are retrieved are the Fruit base class fields. But is there some way to get the child class attributes as well without multiple expensive database transactions? (For example, I could get the array, then retrieve the child Fruit classes by the id of each array element). thanks in advance, Chuck

  • Get instance of type inheriting from base class, implementing interface, using StructureMap

    - by Ben
    Continuing on my quest for a good plugin implementation I have been testing the StructureMap assembly scanning features. All plugins will inherit from abstract class PluginBase. This will provide access to common application services such as logging. Depending on it's function, each plugin may then implement additional interfaces, for example, IStartUpTask. I am initializing my plugins like so: Scan(x => { x.AssembliesFromPath(HttpContext.Current.Server.MapPath("~/Plugins"), assembly => assembly.GetName().Name.Contains("Extension")); x.AddAllTypesOf<PluginBase>(); }); The difficulty I am then having is how to work against the interface (not the PluginBase) in code. It's easy enough to work with PluginBase: var plugins = ObjectFactory.GetAllInstances<PluginBase>(); foreach (var plugin in plugins) { } But specific functionality (e.g. IStartUpTask.RunTask) is tied to the interface, not the base class. I appreciate this may not be specific to structuremap (perhaps more a question of reflection). Thanks, Ben

  • Ignoring build number when referencing dll

    - by brickner
    I have one solution with a .NET 4.0 project (C#) that produces a delayed signed dll, that I dotfuscate and sign. EDIT: This is how I version the dll: [assembly: AssemblyVersion("0.7.0.*")] [assembly: AssemblyFileVersion("0.7.0.0")] I have another solution with a .NET 4.0 project (C++/CLI) that references the signed dll and produces a signed dll (actually, delayed signed and signed in a post build because of a flaw in the C++ build system). The problem is that the reference to the dll contains a specific version number, which includes even the build number (I want to have a build number). Every time I build the referenced dll, I have to change the project settings file (.vcxproj) so it reference the new version dll. Since I work with source control, this is very inconvenient (different computers might have different build numbers since each computer build its own referenced dll - the referenced dll is not in the source control). If I don't change the reference, I get a warning: warning MSB3245: Could not resolve this reference. Could not locate the assembly... And many errors like this: error C3083: 'Foo': the symbol to the left of a '::' must be a type These are resolved once I change the reference. How do I make the reference ignore the build number or even the entire version number?

  • backbone.js Model.get() returns undefined, scope using coffeescript + coffee toaster?

    - by benipsen
    I'm writing an app using coffeescript with coffee toaster (an awesome NPM module for stitching) that builds my app.js file. Lots of my application classes and templates require info about the current user so I have an instance of class User (extends Backbone.Model) stored as a property of my main Application class (extends Backbone.Router). As part of the initialization routine I grab the user from the server (which takes care of authentication, roles, account switching etc.). Here's that coffeescript: @user = new models.User @user.fetch() console.log(@user) console.log(@user.get('email')) The first logging statement outputs the correct Backbone.Model attributes object in the console just as it should: User _changing: false _escapedAttributes: Object _pending: Object _previousAttributes: Object _silent: Object attributes: Object account: Object created_on: "1983-12-13 00:00:00" email: "[email protected]" icon: "0" id: "1" last_login: "2012-06-07 02:31:38" name: "Ben Ipsen" roles: Object __proto__: Object changed: Object cid: "c0" id: "1" __proto__: ctor app.js:228 However, the second returns undefined despite the model attributes clearly being there in the console when logged. And just to make things even more interesting, typing "window.app.user.get('email')" into the console manually returns the expected value of "[email protected]"... ? Just for reference, here's how the initialize method compiles into my app.js file: Application.prototype.initialize = function() { var isMobile; isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/); this.helpers = new views.DOMHelpers().initialize().setup_viewport(isMobile); this.user = new models.User(); this.user.fetch(); console.log(this.user); console.log(this.user.get('email')); return this; }; I initialize the Application controller in my static HTML like so: jQuery(document).ready(function(){ window.app = new controllers.Application(); }); Suggestions please and thank you!

  • How can I create an executable to run on a certain processor architecture (instead of certain OS)?

    - by CrazyJugglerDrummer
    So I take my C++ program in Visual studio, compile, and it'll spit out a nice little EXE file. But EXEs will only run on windows, and I hear a lot about how C/C++ compiles into assembly language, which is runs directly on a processor. The EXE runs with the help of windows, or I could have a program that makes an executable that runs on a mac. But aren't I compiling C++ code into assembly language, which is processor specific? My Insights: I'm guessing I'm probably not. I know there's an Intel C++ compiler, so would it make processor-specific assembly code? EXEs run on windows, so they advantage of tons of things already set up, from graphics packages to the massive .NET framework. A processor-specific executable would be literally starting from scratch, with just the instruction set of the processor. Would this executable be a file-type? We could be running windows and open it, but then would control switch to processor only? I assume this executable would be something like an operating system, in that it would have to be run before anything else was booted up, and have only the processor instruction set to "use".

  • What is the best database structure for this scenario?

    - by Ricketts
    I have a database that is holding real estate MLS (Multiple Listing Service) data. Currently, I have a single table that holds all the listing attributes (price, address, sqft, etc.). There are several different property types (residential, commercial, rental, income, land, etc.) and each property type share a majority of the attributes, but there are a few that are unique to that property type. My question is the shared attributes are in excess of 250 fields and this seems like too many fields to have in a single table. My thought is I could break them out into an EAV (Entity-Attribute-Value) format, but I've read many bad things about that and it would make running queries a real pain as any of the 250 fields could be searched on. If I were to go that route, I'd literally have to pull all the data out of the EAV table, grouped by listing id, merge it on the application side, then run my query against the in memory object collection. This also does not seem very efficient. I am looking for some ideas or recommendations on which way to proceed. Perhaps the 250+ field table is the only way to proceed. Just as a note, I'm using SQL Server 2012, .NET 4.5 w/ Entity Framework 5, C# and data is passed to asp.net web application via WCF service. Thanks in advance.

  • ActiveRecord exceptions not rescued

    - by zoopzoop
    I have the following code block: unless User.exist?(...) begin user = User.new(...) # Set more attributes of user user.save! rescue ActiveRecord::RecordInvalid, ActiveRecord::RecordNotUnique => e # Check if that user was created in the meantime user = User.exists?(...) raise e if user.nil? end end The reason is, as you can probably guess, that multiple processes might call this method at the same time to create the user (if it doesn't already exist), so while the first one enters the block and starts initializing a new user, setting the attributes and finally calling save!, the user might already be created. In that case I want to check again if the user exists and only raise the exception if it still doesn't (= if no other process has created it in the meantime). The problem is, that regularly ActiveRecord::RecordInvalid exceptions are raised from the save! and not rescued from the rescue block. Any ideas? EDIT: Alright, this is weird. I must be missing something. I refactored the code according to Simone's tip to look like this: unless User.find_by_email(...).present? # Here we know the user does not exist yet user = User.new(...) # Set more attributes of user unless user.save # User could not be saved for some reason, maybe created by another request? raise StandardError, "Could not create user for order #{self.id}." unless User.exists?(:email => ...) end end Now I got the following exception: ActiveRecord::RecordNotUnique: Mysql::DupEntry: Duplicate entry '[email protected]' for key 'index_users_on_email': INSERT INTO `users` ... thrown in the line where it says 'unless user.save'. How can that be? Rails thinks the user can be created because the email is unique but then the Mysql unique index prevents the insert? How likely is that? And how can it be avoided?

  • How to keep your unit tests simple and isolated and still guarantee DDD invariants ?

    - by ian31
    DDD recommends that the domain objects should be in a valid state at any time. Aggregate roots are responsible for guaranteeing the invariants and Factories for assembling objects with all the required parts so that they are initialized in a valid state. However this seems to complicate the task of creating simple, isolated unit tests a lot. Let's assume we have a BookRepository that contains Books. A Book has : an Author a Category a list of Bookstores you can find the book in These are required attributes : a book has to have an author, a category and at least a book store you can buy the book from. There's likely to be a BookFactory since it is quite a complex object, and the Factory will initialize the Book with at least all the mentioned attributes. Now we want to unit test a method of the BookRepository that returns all the Books. To test if the method returns the books, we have to set up a test context (the Arrange step in AAA terms) where some Books are already in the Repository. If the only tool at our disposal to create Book objects is the Factory, the unit test now also uses and is dependent on the Factory and inderectly on Category, Author and Store since we need those objects to build up a Book and then place it in the test context. Would you consider this is a dependency in the same way that in a Service unit test we would be dependent on, say, a Repository that the Service would call ? How would you solve the problem of having to re-create a whole cluster of objects in order to be able to test a simple thing ? How would you break that dependency and get rid of all these attributes we don't need in our test ? By using mocks or stubs ? If you mock up things a Repository contains, what kind of mock/stubs would you use as opposed to when you mock up something the object under test talks to or consumes ?

  • VS2010 renders controls JS awkwardly

    I have created a Website Project in VS2010. My Controls are not rendered correctly. The JS that is produced is not correctly formatted. Here is an example: protected void Page_PreRender(object sender, EventArgs e) { if (!IsPostBack) { objListBox.Attributes.Add("onchange", "Control_doPostBack('" + objListBox.ClientID + "','ListBox_OnClick'); return false;"); objListBox.Attributes.Add("onblur", "Control_doPostBack('" + trListbox.ClientID + "','ListBox_OnBlur'); return false;"); img.Attributes.Add("onclick", "Control_doPostBack('" + trListbox.ClientID + "','IMG_OnClick'); return false;"); } } and the responding control is rendered as: <select size="4" name="ctl00$PlaceHolder_Content$drop$objListBox" onchange="Control_doPostBack(&#39;PlaceHolder_Content_drop_objListBox&#39;,&#39;ListBox_OnClick&#39;); return false;setTimeout(&#39;__doPostBack(\&#39;ctl00$PlaceHolder_Content$drop$objListBox\&#39;,\&#39;\&#39;)&#39;, 0)" id="PlaceHolder_Content_drop_objListBox" onblur="Control_doPostBack(&#39;PlaceHolder_Content_drop_trListbox&#39;,&#39;ListBox_OnBlur&#39;); return false;" style="position:absolute;"> </select> As you can see, the ' are rendered to &#39 which screwes up the Browser. Is there a tweak to msbuild or inside the project properties? Any help is highly appreciated.

  • Execute binary from memory in C# .net with binary protected from a 3rd party software

    - by NoobTom
    i've the following scenario: i've a C# application.exe i pack application.exe inside TheMida, a software anti-piracy/reverse engineering. i encrypt application.exe with aes256. (i wrote my own aes encryption/decryption and it is working) Now, when i want to execute my application i do the following: decrypt application.exe in memory execute the application.exe with the following code: BinaryReader br = new BinaryReader(decOutput); byte[] bin = br.ReadBytes(Convert.ToInt32(decOutput.Length)); decOutput.Close(); br.Close(); // load the bytes into Assembly Assembly a = Assembly.Load(bin); // search for the Entry Point MethodInfo method = a.EntryPoint; if (method != null) { // create an istance of the Startup form Main method object o = a.CreateInstance(method.Name); // invoke the application starting point method.Invoke(o, null); the application does not execute correctly. Now, the problem i think, is that this method is only to execute .NET executable. Since i packed my application.exe inside TheMida this does not work. Is there a workaround to this situation? Any suggestion? Thank you in advance.

  • Set Custom ASP.NET UserControl variables when its in a Repeater

    - by tnriverfish
    <%@ Register Src="~/Controls/PressFileDownload.ascx" TagName="pfd" TagPrefix="uc1" %> <asp:Repeater id="Repeater1" runat="Server" OnItemDataBound="RPTLayer_OnItemDataBound"> <ItemTemplate> <asp:Label ID="LBLHeader" Runat="server" Visible="false"></asp:Label> <asp:Image ID="IMGThumb" Runat="server" Visible="false"></asp:Image> <asp:Label ID="LBLBody" Runat="server" class="layerBody"></asp:Label> <uc1:pfd ID="pfd1" runat="server" ShowContainerName="false" ParentContentTypeId="55" /> <asp:Literal ID="litLayerLinks" runat="server"></asp:Literal> </ItemTemplate> </asp:Repeater> System.Web.UI.WebControls.Label lbl; System.Web.UI.WebControls.Literal lit; System.Web.UI.WebControls.Image img; System.Web.UI.WebControls.HyperLink hl; System.Web.UI.UserControl uc; I need to set the ParentItemID variable for the uc1:pdf listed inside the repeater. I thought I should be able to find uc by looking in the e.Item and then setting it somehow. I think this is the part where I'm missing something. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes["ParentItemID"] = i.ItemID.ToString(); } Any thoughts would be appreciated. Also tried this with similar results... when I debug inside my usercontrol (pfd1) the parameters I am trying to set have not been set. uc = (UserControl)e.Item.FindControl("pfd1"); if (uc != null) { uc.Attributes.Add("ContainerID", _cid.ToString()); uc.Attributes.Add("ParentItemId", i.ItemID.ToString()); }

  • WCF service reference namespace differs from original

    - by Thorarin
    I'm having a problem regarding namespaces used by my service references. I have a number of WCF services, say with the namespace MyCompany.Services.MyProduct (the actual namespaces are longer). As part of the product, I'm also providing a sample C# .NET website. This web application uses the namespace MyCompany.MyProduct. During initial development, the service was added as a project reference to the website and uses directly. I used a factory pattern that returns an object instance that implements MyCompany.Services.MyProduct.IMyService. So far, so good. Now I want to change this to use an actual service reference. After adding the reference and typing MyCompany.Services.MyProduct in the namespace textbox, it generates classes in the namespace MyCompany.MyProduct.MyCompany.Services.MyProduct. BAD! I don't want to have to change using directives in several places just because I'm using a proxy class. So I tried prepending the namespace with global::, but that is not accepted. Note that I hadn't even deleted the original assembly references yet, and "reuse types" is enabled, but no reusing was done, apparently. However, I don't want to keep the assembly references around in my sample website for it to work anyway. The only solution I've come up with so far is setting the default namespace for my web application to MyCompany (because it cannot be empty), and adding the service reference as Services.MyProduct. Suppose that a customer wants to use my sample website as a starting point, and they change the default namespace to OtherCompany.Whatever, this will obviously break my workaround. Is there a good solution to this problem? To summarize: I want to generate a service reference proxy in the original namespace, without referencing the assembly. Note: I have seen this question, but there was no solution provided that is acceptable for my use case. Edit: As John Saunders suggested, I've submitted some feedback to Microsoft about this: Feedback item @ Microsoft Connect

  • Modelling deterministic and nondeterministic data separately

    - by Superstringcheese
    I'm working with the Microsoft ADO.NET Entity Framework for a game project. Following the advice of other posters on SO, I'm considering modelling deterministic and nondeterministic data separately. The idea for this came from a discussion on multiplayer games, but it seemed to make sense in a single-player scenario as well. Deterministic (things that aren't going to change during gameplay) Attributes (Strength, Agility, etc.) and their descriptions Skills and their descriptions and requirements Races, Factions, Equipment, etc. Base Attribute/Skill/Equipment loadouts for monsters Nondeterministic (things that will change a lot during gameplay) Beings' current AttributeModifers (Potion of Might = +10 Strength), current health and mana, etc. Player inventory, cash, experience, level Player quests states Player FactionRelationships ...and so on. My deterministic model would serve as a set of constants. My nondeterministic model would provide my on-the-fly operable data and would be serialized to a savegame file to maintain game state between play sessions. The data store will be an embedded SQL Compact database. So I might want to create relations between my Attributes table (deterministic model) and my BeingAttributeModifiers table (nondeterministic model), but how do I set that up across models? Det model/db Nondet model/db ____________ ________________________ |Attributes | |PlayerAttributeModifiers| |------------| |------------------------| |Id | |Id | |Name | |AttributeId | |Description | |SourceId | ------------ |Value | ------------------------ Should I use two separate models (edmx) that transact with a single database containing both deterministic-type and nondeterministic-type tables? Or should/can I use two separate databases in one model? Or two models each with their own database? With distinct models/dbs it seems like this will get really complicated and I'll end up fighting EF a lot, rolling my own transaction code, and generally losing out on a lot of the advantages of the framework. I know these are vague questions, I'm just looking for a sanity check before I forge ahead any further.

  • Passing arguments and values from HTML to jQuery (events)

    - by Jaroslav Moravec
    What is the practice to pass arguments from HTML to jQuery events function. For example getting id of row from db: <tr class="jq_killMe" id="thisItemId-id"> ... </tr> and jQuery: $(".jq_killMe").click(function () { var tmp = $(this).attr('id).split("-"); var id = tmp[0] // ... } What's the best practise, if I want to pass more than one argument? Is it better not to use jQuery? For example: <tr onclick="killMe('id')"> ... </tr> I didn't find the answer on my question, I will be glad even for links. Thanks. Edit (pre solution) So you suggested two methods to do that: Add custom attributes to element (XHTML) Use attribute ID and parse it by regex Attribute data-* attributes in HTML5 Use hidden children elements I like first solution, but... I would like to (I have to (employer)) produce valid code. Here is a nice question and answers: http://stackoverflow.com/questions/994856/so-what-if-custom-html-attributes-arent-valid-xhtml And the second is not so pretty as the first, but valid. So the compromise is... The third is the solution for future, but here is a lot of CMS where we have to use XHTML or HTML4. (And HTML5 is the long process)

  • Py_INCREF/DECREF: When

    - by Izz ad-Din Ruhulessin
    Is one correct in stating the following: If a Python object is created in a C function, but the function doesn't return it, no INCREF is needed, but a DECREF is. [false]If the function does return it, you do need to INCREF, in the function that receives the return value.[/false] When assigning C typed variables as attributes, like double, int etc., to the Python object, no INCREF or DECREF is needed. Assigning Python objects as attributes to your other Python objects goes like this: PyObject *foo; foo = bar // A Python object tmp = self->foo; Py_INCREF(foo); self->foo = foo; Py_XDECREF(tmp); //taken from the manual, but it is unclear if this works in every situation EDIT: -- can I safely use this in every situation? (haven't run into one where it caused me problems) dealloc of a Python object needs to DECREF for every other Python object that it has as an attribute, but not for attributes that are C types. Edit With 'C type as an attribute I mean bar and baz: typedef struct { PyObject_HEAD PyObject *foo; int bar; double baz; } FooBarBaz;

  • Unity in C# for Platform Specific Implementations

    - by DxCK
    My program has heavy interaction with the operating system through Win32API functions. now i want to migrate my program to run under Mono under Linux (No wine), and this requires different implementations to the interaction with the operating system. I started designing a code that can have different implementation for difference platform and is extensible for new future platforms. public interface ISomeInterface { void SomePlatformSpecificOperation(); } [PlatformSpecific(PlatformID.Unix)] public class SomeImplementation : ISomeInterface { #region ISomeInterface Members public void SomePlatformSpecificOperation() { Console.WriteLine("From SomeImplementation"); } #endregion } public class PlatformSpecificAttribute : Attribute { private PlatformID _platform; public PlatformSpecificAttribute(PlatformID platform) { _platform = platform; } public PlatformID Platform { get { return _platform; } } } public static class PlatformSpecificUtils { public static IEnumerable<Type> GetImplementationTypes<T>() { foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies()) { foreach (Type type in assembly.GetTypes()) { if (typeof(T).IsAssignableFrom(type) && type != typeof(T) && IsPlatformMatch(type)) { yield return type; } } } } private static bool IsPlatformMatch(Type type) { return GetPlatforms(type).Any(platform => platform == Environment.OSVersion.Platform); } private static IEnumerable<PlatformID> GetPlatforms(Type type) { return type.GetCustomAttributes(typeof(PlatformSpecificAttribute), false) .Select(obj => ((PlatformSpecificAttribute)obj).Platform); } } class Program { static void Main(string[] args) { Type first = PlatformSpecificUtils.GetImplementationTypes<ISomeInterface>().FirstOrDefault(); } } I see two problems with this design: I can't force the implementations of ISomeInterface to have a PlatformSpecificAttribute. Multiple implementations can be marked with the same PlatformID, and i dont know witch to use in the Main. Using the first one is ummm ugly. How to solve those problems? Can you suggest another design?

  • Loading .dll/.exe from file into temporary AppDomain throws Exception

    Hi Gang, I am trying to make a Visual Studio AddIn that removes unused references from the projects in the current solution (I know this can be done, Resharper does it, but my client doesn't want to pay for 300 licences). Anyhoo, I use DTE to loop through the projects, compile their assemblies, then reflect over those assemblies to get their referenced assemblies and cross-examine the .csproj file. Problem: since the .dll/.exe I loaded up with Reflection doesn't unload until the app domian unloads, it is now locked and the projects can't be built again because VS tries to re-create the files (all standard stuff). I have tried creating temporary files, then reflecting over them...no worky, still have locked original files (I totally don’t understand that BTW). Now I am now going down the path of creating a temporary AppDomain to load the files into and then destroy. I am having problems loading the files though: The way I understand AddDomain.Load is that I should create and send a byte array of the assembly to it. I do that: FileStream fs = new FileStream(assemblyFile, FileMode.Open); byte[] assemblyFileBuffer = new byte[(int)fs.Length]; fs.Read(assemblyFileBuffer, 0, assemblyFileBuffer.Length); fs.Close(); AppDomainSetup domainSetup = new AppDomainSetup(); domainSetup.ApplicationBase = assemblyFileInfo.Directory.FullName; AppDomain tempAppDomain = AppDomain.CreateDomain("TempAppDomain", null, domainSetup); Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer); The last line throws an exception: "Could not load file or assembly 'WindowsFormsApplication1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"WindowsFormsApplication3, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"}" Any help or thoughts would be greatly appreciated. My head is lopsided from beating it against the wall... Thanks, Dan
