Extracting the source code of a facebook page with JavaScript

- by Hafizi Vilie

If I write code in the JavaScript console of Chrome, I can retrieve the whole HTML source code by entering: var a = document.body.InnerHTML; alert(a); For fb_dtsg on Facebook, I can easily extract it by writing: var fb_dtsg = document.getElementsByName('fb_dtsg')[0].value; Now, I am trying to extract the code "h=AfJSxEzzdTSrz-pS" from the Facebook Page. The h value is especially useful for Facebook reporting. How can I get the h value for reporting? I don't know what the h value is; the h value is totally different when you communicate with different users. Without that h correct value, you can not report. Actually, the h value is AfXXXXXXXXXXX (11 character values after 'Af'), that is what I know. Do you have any ideas for getting the value or any function to generate on Facebook page. The Facebook Source snippet is below, you can view source on facebook profile, and search h=Af, you will get the value: <code class="hidden_elem" id="ukftg4w44">  </code> Please guide me. How can extract the value exactly? I tried with following code, but the comment block prevent me to extract the code. How can extract the value which is inside comment block? var a = document.getElementsByClassName('hidden_elem')[3].innerHTML;alert(a);

Handwritten linked list is segfaulting and I don't understand why

- by Born2Smile

Hi I was working on a bit of fun, making an interface to run gnuplot from within c++, and for some reason the my linked list implementation fails. The code below fails on the line plots-append(&plot). Stepping through the code I discovered that for some reason the destructor ~John() is called immediately after the constructor John(), and I cannot seem to figure out why. The code included below is a stripped down version operating only on Plot*. Originally I made the linked list as a template class. And it worked fine as ll<int and ll<char* but for some reason it fails as ll<Plot*. Could youp please help me figure out why it fails? and perhaps help me understand how to make it work? In advance: Thanks a heap! //B2S #include <string.h class Plot{ char title[80]; public: Plot(){ } }; class Link{ Plot* element; Link* next; Link* prev; friend class ll; }; class ll{ Link* head; Link* tail; public: ll(){ head = tail = new Link(); head-prev = tail-prev = head-next = tail-next = head; } ~ll(){ while (head!=tail){ tail = tail-prev; delete tail-next; } delete head; } void append(Plot* element){ tail-element = element; tail-next = new Link(); tail-next-prev = tail; tail-next = tail; } }; class John{ ll* plots; public: John(){ plots= new ll(); } ~John(){ delete plots; } John(Plot* plot){ John(); plots-append(plot); } }; int main(){ Plot p; John k(&p); }

Is Microformat's date-value-pattern fully accessible?

- by Stephen

Has there been an announcement (outside microformats.org) that the value-class-pattern is fully accessible? e.g. given <abbr class="value" title="2008-06-24">this Tuesday</abbr>, will a screen reader say "24 June 2008" or will it say "2008 dash 6 dash 24"? History Microformats came along, and were great, except that dates etc were stored in abbr tags: <abbr class="dtstart" title="20070312T1700-06"> March 12, 2007 at 5 PM, Central Standard Time </abbr>` This lead to screen readers doing ridiculous things as noted in hAccessibility. Now that microformats.org have released the value-class-pattern it's a lot better. But I'm left unable to find a declaration from WaSP (or another accessibility source not directly tied to microformats) that declaratively states that they are now accessible to screen readers etc.

Using string constants in implicit conversion

- by kornelijepetak

Consider the following code: public class TextType { public TextType(String text) { underlyingString = text; } public static implicit operator String(TextType text) { return text.underlyingString; } private String underlyingString; } TextType text = new TextType("Something"); String str = text; // This is OK. But I want to be able do the following, if possible. TextType textFromStringConstant = "SomeOtherText"; I can't extend the String class with the TextType implicit operator overload, but is there any way to assign a literal string to another class (which is handled by a method or something)? String is a reference type so when they developed C# they obviously had to use some way to get a string literal to the class. I just hope it's not hardcoded into the language.

Listing all shared memory segments used by a process on AIX5.3+

- by Frank Meerkötter

I would like to find all shared memory segments used by a given process. I am especially interested in figuring out the shmid so i can use it in calls to shmctl(). On Solaris i would just read /proc/$PID/map to figure out that information (field pr_shmid). The contents of that file are defined by struct prmap_t in sys/procfs. AIX also has a /proc/$PID/map file. There is also a struct prmap but unfortunately it is missing the pr_shmid field. Any ideas how i can achieve this on AIX5.3+?

resolving overloads in boost.python

- by swarfrat

I have a C++ class like this: class ConnectionBase { public: ConnectionBase(); template <class T> Publish(const T&); private: virtual void OnEvent(const Overload_a&) {} virtual void OnEvent(const Overload_b&) {} }; My templates & overloads are a known fixed set of types at compile time. The application code derives from ConnectionBase and overrides OnEvent for the events it cares about. I can do this because the set of types is known. OnEvent is private because the user never calls it, the class creates a thread that calls it as a callback. The C++ code works. I have wrapped this in boost.python, I can import it and publish from python. I want do create the equivalent of the following in python : class ConnectionDerived { public: ConnectionDerived(); private: virtual void OnEvent(const Overload_b&) { // application code } }; But ... since python isn't typed, and all the boost.python examples I've seen dealing with internals are on the C++ side, I'm a little puzzled as to how to do this. How do I override specific overloads?

Is a switch statement the fastest way to implement operator interpretation in Java

- by Mordan

Is a switch statement the fastest way to implement operator interpretation in Java public boolean accept(final int op, int x, int val) { switch (op) { case OP_EQUAL: return x == val; case OP_BIGGER: return x > val; case OP_SMALLER: return x < val; default: return true; } } In this simple example, obviously yes. Now imagine you have 1000 operators. would it still be faster than a class hierarchy? Is there a threshold when a class hierarchy becomes more efficient in speed than a switch statement? (in memory obviously not) abstract class Op { abstract public boolean accept(int x, int val); } And then one class per operator.

IoC and dataContext disposing in asp.net mvc 2 application

- by zerkms

I have the Global.asax like the code below: public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { // .... } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(typeof(IOCControllerFactory)); } } public class IOCControllerFactory : DefaultControllerFactory { private readonly IKernel kernel; public IOCControllerFactory() { kernel = new StandardKernel(new NanocrmContainer()); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType == null) return base.GetControllerInstance(requestContext, controllerType); var controller = kernel.TryGet(controllerType) as IController; if (controller == null) return base.GetControllerInstance(requestContext, controllerType); var standartController = controller as Controller; if (standartController is IIoCController) ((IIoCController)standartController).SetIoc(kernel); return standartController; } class NanocrmContainer : Ninject.Modules.NinjectModule { public override void Load() { // ... Bind<DomainModel.Entities.db>().ToSelf().InRequestScope().WithConstructorArgument("connection", "Data Source=lims;Initial Catalog=nanocrm;Persist Security Info=True;User ID=***;Password=***"); } } } In this case if somewhere it is the class, defined like: public class UserRepository : IUserRepository { private db dataContext; private IUserGroupRepository userGroupRepository; public UserRepository(db dataContext, IUserGroupRepository userGroupRepository) { this.dataContext = dataContext; this.userGroupRepository = userGroupRepository; } } then the dataContext instance is created (if no one was created in this request scope) by Ninject. So the trouble now is - where to invoke dataContext method .Dispose()?

Review my ASP.NET Authentication code.

- by Niels Bosma

I have had some problems with authentication in ASP.NET. I'm not used most of the built in authentication in .NET. I gotten some complaints from users using Internet Explorer (any version - may affect other browsers as well) that the login process proceeds but when redirected they aren't authenticated and are bounced back to loginpage (pages that require authentication check if logged in and if not redirect back to loginpage). Can this be a cookie problem? Do I need to check if cookies are enabled by the user? What's the best way to build authentication if you have a custom member table and don't want to use ASP.NET login controls? Here my current code: using System; using System.Linq; using MyCompany; using System.Web; using System.Web.Security; using MyCompany.DAL; using MyCompany.Globalization; using MyCompany.DAL.Logs; using MyCompany.Logging; namespace MyCompany { public class Auth { public class AuthException : Exception { public int StatusCode = 0; public AuthException(string message, int statusCode) : base(message) { StatusCode = statusCode; } } public class EmptyEmailException : AuthException { public EmptyEmailException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMPTY_EMAIL, 6) { } } public class EmptyPasswordException : AuthException { public EmptyPasswordException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMPTY_PASSWORD, 7) { } } public class WrongEmailException : AuthException { public WrongEmailException() : base(Language.RES_ERROR_LOGIN_CLIENT_WRONG_EMAIL, 2) { } } public class WrongPasswordException : AuthException { public WrongPasswordException() : base(Language.RES_ERROR_LOGIN_CLIENT_WRONG_PASSWORD, 3) { } } public class InactiveAccountException : AuthException { public InactiveAccountException() : base(Language.RES_ERROR_LOGIN_CLIENT_INACTIVE_ACCOUNT, 5) { } } public class EmailNotValidatedException : AuthException { public EmailNotValidatedException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMAIL_NOT_VALIDATED, 4) { } } private readonly string CLIENT_KEY = "9A751E0D-816F-4A92-9185-559D38661F77"; private readonly string CLIENT_USER_KEY = "0CE2F700-1375-4B0F-8400-06A01CED2658"; public Client Client { get { if(!IsAuthenticated) return null; if(HttpContext.Current.Items[CLIENT_KEY]==null) { HttpContext.Current.Items[CLIENT_KEY] = ClientMethods.Get<Client>((Guid)ClientId); } return (Client)HttpContext.Current.Items[CLIENT_KEY]; } } public ClientUser ClientUser { get { if (!IsAuthenticated) return null; if (HttpContext.Current.Items[CLIENT_USER_KEY] == null) { HttpContext.Current.Items[CLIENT_USER_KEY] = ClientUserMethods.GetByClientId((Guid)ClientId); } return (ClientUser)HttpContext.Current.Items[CLIENT_USER_KEY]; } } public Boolean IsAuthenticated { get; set; } public Guid?

Setting nested object to null when combobox has empty value

- by Javi

Hello, I have a Class which models a User and another which models his country. Something like this: public class User{ private Country country; //other attributes and getter/setters } public class Country{ private Integer id; private String name; //other attributes and getter/setters } I have a Spring form where I have a combobox so the user can select his country or can select the undefined option to indicate he doen't want to provide this information. So I have something like this: <form:select path="country"> <form:option value="">-Select one-</form:option> <form:options items="${countries}" itemLabel="name" itemValue="id"/> </form:select> In my controller I get the autopopulated object with the user information and I want to have country set to null when the "-Select one-" option has been selected. So I have set a initBinder with a custom editor like this: @InitBinder protected void initBinder(WebDataBinder binder) throws ServletException { binder.registerCustomEditor(Country.class, "country", new CustomCountryEditor()); } and my editor do something like this: public class CustomCountryEditor(){ @Override public String getAsText() { //I return the Id of the country } @Override public void setAsText(String str) { //I search in the database for a country with id = new Integer(str) //and set country to that value //or I set country to null in case str == null } } When I submit the form it works because when I have country set to null when I have selected "-Select one-" option or the instance of the country selected. The problem is that when I load the form I have a method like the following one to load the user information. @ModelAttribute("user") public User getUser(){ //loads user from database } The object I get from getUser() has country set to a specific country (not a null value), but in the combobox is not selected any option. I've debugged the application and the CustomCountryEditor works good when setting and getting the text, thoughgetAsText method is called for every item in the list "countries" not only for the "country" field. Any idea? Is there a better way to set null the country object when I select no country option in the combobox? Thanks

constructor in Perl with an array(OOPS)

whats the difference between these two 'new' constructors in perl? 1) sub new { my $class = shift; my $self = {}; $self->{firstName} = undef; $self->{lastName} = undef; $self->{PEERS} = []; bless ($self, $class); return $self; } 2) sub new { my $class = shift; my $self = { _firstName => shift, _lastName => shift, _ssn => shift, }; bless $self, $class; return $self; } I am using the 2nd one so far, but i need to implement the arrays in perl? can you suggest a way to do it with the 2nd 'new' constructor

HtmlHelper Getting the route name

- by Simon G

Hi, I've created a html helper that adds a css class property to a li item if the user is on the current page. The helper looks like this: public static string MenuItem( this HtmlHelper helper, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class if ( currentControllerName.Equals( controllerName, StringComparison.CurrentCultureIgnoreCase ) && currentActionName.Equals( actionName, StringComparison.CurrentCultureIgnoreCase ) ) builder.AddCssClass( "active" ); // Add link builder.InnerHtml = helper.ActionLink( linkText, actionName, controllerName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } I want to expand this class so I can pass a route name to the helper and if the user is on that route then it adds the css class to the li item. However I'm having difficulty finding the route the user is on. Is this possible? The code I have so far is: public static string MenuItem( this HtmlHelper helper, string linkText, string routeName, object routeValues, object htmlAttributes ) { string currentControllerName = ( string )helper.ViewContext.RouteData.Values["controller"]; string currentActionName = ( string )helper.ViewContext.RouteData.Values["action"]; var builder = new TagBuilder( "li" ); // Add selected class // Some code for here // if ( routeName == currentRoute ) AddCssClass; // Add link builder.InnerHtml = helper.RouteLink( linkText, routeName, routeValues, htmlAttributes ); // Render Tag Builder return builder.ToString( TagRenderMode.Normal ); } BTW I'm using MVC 1.0. Thanks

Default template arguments for function templates

- by Arman

Why are default template arguments only allowed on class templates? Why can't we define a default type in a member function template? For example: struct mycclass { template<class T=int> void mymember(T* vec) { // ... } }; Instead, C++ forces that default template arguments are only allowed on a class template.

How to select form input based on label inner HTML?

- by Shane

I have multiple forms that are dynamically created with different input names and id's. The only thing unique they will have is the inner HTML of the label. Is it possible to select the input via the label inner HTML with jQuery? Here is an example of one of my patient date of birth blocks, there are many and all unique except for innerHTML. <div class="iphorm-element-spacer iphorm-element-spacer-text iphorm_1_8-element-spacer"> <label for="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8">events=Object { mouseover=[1], mouseout=[1]}handle=function()data=Object { InFieldLabels={...}} Patient DOB <span class="iphorm-required">*</span> </label> <div class="iphorm-input-wrap iphorm-input-wrap-text iphorm_1_8-input-wrap"> <input id="iphorm_081a9e2e6b9c83d70496906bb4671904150cf4b43c0cb1_8" class="iphorm-element-text iphorm_1_8" type="text" value="" name="iphorm_1_8">events=Object { focus=[1], blur=[1], keydown=[1], more...}handle=function() </div> <div class="iphorm-errors-wrap iphorm-hidden"> </div> This is in a Wordpress Plugin and because we are building to allow employees to edit their sites (this is actually a Wordpress Network), we do not want to alter the plugin if possible. Note that the label "for" and the input "id" share the same dynamic key, so this might be a way to maybe get the id, but wanted to see if there is a shorter way of doing this.

Create 2 connection pools using c3p0 in Jetty

- by Mike

Hello, I'm trying to set up a maven web project that runs Jetty. In this project, I need 2 JNDIs... my plan is to configure 2 connection pools using c3p0 in Jetty. So, I created WEB-INF/jetty-env.xml, and I have the following:- <Configure class="org.mortbay.jetty.webapp.WebAppContext"> <New id="ds1" class="org.mortbay.jetty.plus.naming.Resource"> <Arg>jdbc/ds1</Arg> <Arg> <New class="com.mchange.v2.c3p0.ComboPooledDataSource"> // ...

JTDS to Sybase - omitted for brevity </New> </Arg> </New> </Configure> When I run jetty, I get this exception:- May 14, 2010 1:16:56 PM com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource getPoolManager INFO: Initializing c3p0 pool... com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> ... ... ...

If I remove either one of the connection pool, it worked. What am I doing wrong? How do I create 2 connection pools in Jetty? Thanks much.

MinGW Doesn't Generate an Object File When Compiling

I'm trying to develop my first EJB with an Example I found, I have the next mistake: Exception in thread "main" java.lang.IllegalStateException: No EJB receiver available for handling [appName:,modulename:HelloWorldSessionBean,distinctname:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@41408b80 at org.jboss.ejb.client.EJBClientContext.requireEJBReceiver(EJBClientContext.java:584) at org.jboss.ejb.client.ReceiverInterceptor.handleInvocation(ReceiverInterceptor.java:119) at org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:181) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:136) at org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:121) at org.jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:104) at $Proxy0.sayHello(Unknown Source) at com.ibytecode.client.EJBApplicationClient.main(EJBApplicationClient.java:16) I use JBOSS 7.1, and the code is this: HelloWorld.java package com.ibytecode.business; import javax.ejb.Remote; @Remote public interface HelloWorld { public String sayHello(); } HelloWorldBean.java package com.ibytecode.businesslogic; import com.ibytecode.business.HelloWorld; import javax.ejb.Stateless; /** * Session Bean implementation class HelloWorldBean */ @Stateless public class HelloWorldBean implements HelloWorld { /** * Default constructor. */ public HelloWorldBean() { } public String sayHello() { return "Hello World !!!"; } } EJBApplicationClient.java: package com.ibytecode.client; import javax.naming.Context; import javax.naming.NamingException; import com.ibytecode.business.HelloWorld; import com.ibytecode.businesslogic.HelloWorldBean; import com.ibytecode.clientutility.ClientUtility; public class EJBApplicationClient { public static void main(String[] args) { // TODO Auto-generated method stub HelloWorld bean = doLookup(); System.out.println(bean.sayHello()); // 4.
