  • Can't access variables from dynamically loaded javascript

    - by Menno
    I'm using a fairly simple system to load javascript dynamically: include = function (url) { var e = document.createElement("script"); e.src = url; e.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(e); }; Let's say I have a file test.js which has the following contents: var foo = 4; Now, in my original script, I want to use include(test.js); console.log(foo); However, I get a 'foo has not been defined' error on this. I'm guessing it has to do with the dynamic script being included as the last child of the <head> tag. How can I get this to work?

  • How to assign the value of document.cookie to your browser cookies?

    - by Ricket
    I'm a developer (and therefore a tester) of a website. Our site accepts any JavaScript or HTML from an user but I haven't been successful in explaining the danger of it, as obvious as it is. So I would like to prove it by logging in as my boss to prove to him that there is definitely a real danger here. I think this will put down any of his arguments and let us move onto filtering content like this. (note this question is not about filtering, or other suggestions on JavaScript tricks) I already know how to steal the value of the document.cookie variable with AJAX and a PHP file, but once you have that string of name=value;name=value;..., how do you apply it to your own browser? This is programming related because I am asking about tools which will help me debug my web program.

  • CDateTimeCtrl - preventing 'focus' change when setting date

    - by WalderFrey
    I'd like to use a CDateTimeCtrl to allow the user to select a non-weekend date. So, if the user increments the day (via a keypress) - and the resulting day is found to fall on a weekend - then the control should skip forward to the following Monday (don't let issues about month changes distract you, it's not relevant). Usually it's not a problem: when I handle the DTN_DATETIMECHANGE notification I can check the new date/time and if it's found to be a weekend then I can call SetTime on the control to update the date. However, if I set the style to DTS_SHOWNONE, this call to SetTime causes the control to shift the input 'focus' (term used loosely) to the 'none' checkbox, e.g. away from the day field. This prevents the user from using keyboard input to continue incrementing the date unless they subsequently use the right arrow key to reset the 'focus', which is just nasty. I would dearly like to prevent this focus shift from occurring. Is it even possible?

  • Undefined / Uninitialized default values in a class

    - by Jir
    Let's suppose you have this class: class A { public: A () {} A (double val) : m_val(val) {} ~A () {} private: double m_val; }; Once I create an instance of A, how can I check if m_val has been initialized/defined? Put it in other words, is there a way to know if m_val has been initialized/defined or not? Something along the lines of the defined operator in Python, I suppose. (But correct me if I'm wrong.) I thought of modifying the class and the c-tors the following way: class A { public: A () : defined(false) {} A (double val) : m_val(val), defined(true) {} ~A () {} private: double m_val; bool defined; }; How do you rate this solution? Any suggestion? TIA, Chris

  • iPhone: Switching Views From Outside Root Controller

    - by senfo
    I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

  • e-commerce clothing site in .NET from the scratch or site copy ? suggestions please

    - by pointlesspolitics
    Hi all, I am thinking to create an e-commerce site for a clothing business. I have bit of a development knowledge in c# .net, html, css and other web technologies. Could you please advise on these questions ? Is it a good idea to create a site from the scratch ? I have a running example of such a site, however it is bit old. So can I start with old site and change the html and code behind ? Some people argue that it is better to use MVC for ecommerce site. Any good reasons ? BTW I don't know MVC, but can learn if I have to use it. It is decided to use .NET but if you have any ideas of better technologies, please let me know. Any ideas and issues related to payment system also welcome. Any answer will be appreciated. Thanks Rgds,

  • Can I correctly debug assemblies loaded with the 'AssemblyResolve' event?

    - by Thiado de Arruda
    I'm experimenting with the AppDomain's 'AssemblyResolve' event by hidding the depedencies for an executable file in another folder. The assemblies seem to beloading and executing fine, however debugging seems to be crazy, sometimes it hits my break points, sometimes it doesnt , and sometimes it hits the same code twice(It seems absurd but I'm sure the code is executing only once). I don't understanding how debuggers works but I guess it has something to do with the PDB files. Anyone got an idea of what might be happening and how can I fix it? Edit: Let me add that I'm calling methods on the dynamically loaded assemblies using reflection, sometimes the method I'm stepping over throws an exception that only pops at a later time.

  • Using module include in OCaml

    - by Geoff
    In OCaml 3.11, I want to "extend" an existing module using the include directive, like so: module MyString = struct include String let trim s = ... end No problem. But now I want to expose this module's type explicitly (i.e. in a .mli file). I want something like this: module MyString : sig include String val trim : string -> string end But the include syntax is not correct because String refers to a module, not a module type (and the compiler does indeed barf). How can I refer to the module type for String here (without having write it out explicitly in a sig expression)? Thanks!

  • Teamcity and Grails

    Hi there, My current requirement is: I have to package my grails app and use teamcity for continuous build.

So that there is no dependency. And the package has everything to run the app. Can anybody please help. Please let me know if you want me to rephrase my question.

  • Split text files Accross threads

    - by Kevin
    The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks

  • Can I use RVM to maintain a single version of Ruby for all users?

    - by Trevor Burnham
    I love RVM. I realize that the main use case for it is letting different users switch between different versions of Ruby. But let's say I'm deploying a Rails app to a server and I just want a single version of Ruby running. In particular, I want 1.9.2, which is a breeze to install with RVM but a pain without it. Is there a way that I can say "I want this to be the canonical Ruby installation for all users" (along with all of its gems) without having to create a bunch of symlinks by hand and change them every time I update to a newer Ruby release?

  • passing Perl method results as a reference

    - by arareko
    Some XML::LibXML methods return arrays instead of references to arrays. Instead of doing this: $self->process_items($xml->findnodes('items/item')); I want to do something like: $self->process_items(\$xml->findnodes('items/item')); So that in process_items() I can dereference the original array instead of creating a copy: sub process_items { my ($self, $items) = @_; foreach my $item (@$items) { # do something... } } I can always store the results of findnodes() into an array and then pass the array reference to my own method, but let's say I want to try a reduced version of my code. Is that the correct syntax for passing the method results or should I use something different? Thanks!

  • NServiceBus - Message Sent to and Removed from Queue, but Never Fire IHandleMessages.Handle

    - by grefly
    First let me state, today is my first day using NSesrviceBus - so I hope my question isn't too elementary. I have managed to set up Sender, Receiver, and Messages projects. When I debug the Sender, I see the messages show up in the configured queue. When I debug the Receiver, the messages are removed from the queue. However, my IHandleMessages Handle event never fires, and no Console output is displayed. I'm sure I've done something wrong (I think I may have mixed tutorials from different versions of NServiceBus) - any suggestions would be appreciated.

  • MySQL - Where - search string - MATCH.

    - by Jamie
    Hi guys, Quick question. I'm in a bit of a rush but if someone could quickly point me in the right direction I would be very very happy. I have a field in the db, let's call it field_a which returns a string in the format "20,50,60,80" etc. I wish to do a query which will search in this field to see if 20 exists. Could I use MySQL MATCH or is there a better way? Thank you!

  • In SQL Server 2008, when would I use a full text index that covered several tables?

    - by Suddy
    I wanted to do a full text search across several related tables in SQL Server 2008. From browsing this site I've realised the best option is via a view, but initially I thought I was meant to add several tables to the same full text index via Management Studio. I started to do this and realised the index would have no idea how they were related, so my question is: when would I want to have a full text index covering several tables in this way? Apologies for the vagueness, I am just trying to satisfy my curiosity after Google let me down.

  • Access to an "upper" instance of a class from another instance of a different class

    - by BorrajaX
    Hello everyone! I have a tricky question and probably what I want to do is not even possible but... who knows... Python seems very flexible and powerful... I'd like to know if there's a way to access to the class (or its fields) where an object is instanciated. Let's say I have: def Class1: def __init__(self): self.title = "randomTitle" self.anotherField = float() self.class2Field = Class2() and the class whose type will be the class2Field: def Class2: def __init__(self): self.field1 = "" self.field2 = "" # . . . # I'd like to know if there's a way to access the instance of Class1 from the instance of Class2 that is declared in Class1 (meaning, accessing the fields of Class1 from the variable self.class2Field in that Class1 instance) I know I can always change the init in Class2 to accept a Class1 parameter, but I'd like to know if there's another way of "climbing" through the class hierachy... Thank you very much!

  • C++/CLI Missing MSVCR90.DLL

    - by Mitch
    I have a c++/cli dll that I load at runtime and which works great in debug mode. If I try and load the dll in release mode it fails to load stating that one or more dependencies are missing. If I run depends against it I am missing MSVCR90.DLL from MSVCM90.DLL. If I check the debug version of the dll it also has the missing dependency, but against the debug (D) version. I have made sure debug/release embed the manifest file. I read something about there being issues with the app loading the dll being build as Any CPU and the dll being built as x86, but I don't see how to set them both to x86. I am using VS2010. Anyway, I've been messing around for a while now and have no idea what is wrong. I'm sure someone out there knows what is going on. Let me know if I need to include additional info.

  • git-svn clone checkouts wrong repo?

    - by hyperboreean
    So I am trying to switch to git, by using git-svn. I am having a svn repo called myrepo from which I want to clone just the project called myproject. The thing is that by running the following command: git svn clone path-to-repo/myrepo/myproject --stdlayout --prefix=svn myproject the whole repo myrepo is cloned rather than just myproject. I tried using -T, -t, -b as well to let git know about the layout of the project, but without any success. I always get the following output: Using higher level of URL: path-to-repo/myrepo/myproject => path-to-repo/myrepo and tries to clone that one. Am I doing something wrong? It might be that the svn repo layout could be broken or git incompatible ?

  • Displaying form validation errors in a template (Symfony)

    Hi, let's say I have a blog with a module "post". now I display a post like this: post/index?id=1 in the index-action i generate a new CommentForm and pass it as $this-form to the template and it is being displayed at the bottom of a post (it's just a textfield, nothing special). form action is set to "post/addcomment". How can I display the validation errors in this form? using setTemplate('index') doesn't work because I would have to pass the id=1 to it... thanks

  • What's an elegant solution to get the property values from two classes (that have the same property

    - by SlipToFall
    Essentially I have to deal with a poorly implemented web service. They have two classes that don't derive from a parent class, but have the same properties (Ughh...). So it looks like this in my web service proxy class file: public partial class Product1 { public int Quantity; public int Price; } public partial class Product2 { public int Quantity; public int Price; } So what's the best way to grab the values from known properties without duplicating the code and casting to their respective classes? I know I probably could use reflection, but that can get ugly. If there is an easier less crazier way to do it (maybe in the new c# features?) please let me know.

    I have a simple goal, I would like to increment a variable but I'm facing the closure problem. I've read why this s happening here How do JavaScript closures work? But I can't find the solution to my problem :/ let's assume this part of code I took from the link. function say667() { // Local variable that ends up within closure var num = 666; var sayAlert = function() { alert(num); //incrementation } num++; return sayAlert; } I would like to increment num within the function and to keep the changes to num. How could I do that ? Here is the JsFiddle where I have my problem, I can't figure out how to increment my totalSize and keep it. http://jsfiddle.net/knLbv/2/ I don't want a local variable that ends up with closure.
