    I'm trying to get the HEAD response with an XMLHttpRequest in Chromium to retrive the location URL of a compressed url, but it fails: var ajax = new XMLHttpRequest(); ajax.onreadystatechange = function() { if (ajax.readyState == 4) alert(ajax.getResponseHeader("Location")) }; ajax.open('HEAD', "http://bit.ly/4Agih5", false); ajax.send(); // Refused to get unsafe header "Location" // Error: NETWORK_ERR: XMLHttpRequest Exception 101

  • Many to Many with LINQ-To-Sql and ASP.NET MVC

    - by Jonathan Stowell
    Hi All, I will restrict this to the three tables I am trying to work with Problem, Communications, and ProbComms. The scenario is that a Student may have many Problems concurrently which may affect their studies. Lecturers may have future communications with a student after an initial problem is logged, however as a Student may have multiple Problems the Lecturer may decide that the discussion they had is related to more than one Problem. Here is a screenshot of the LINQ-To-Sql representation of my DB: LINQ-To-Sql Screenshot At the moment in my StudentController I have a StudentFormViewModel Class: // //ViewModel Class public class StudentFormViewModel { IProbCommRepository probCommRepository; // Properties public Student Student { get; private set; } public IEnumerable<ProbComm> ProbComm { get; private set; } // // Dependency Injection enabled constructors public StudentFormViewModel(Student student, IEnumerable<ProbComm> probComm) : this(new ProbCommRepository()) { this.Student = student; this.ProbComm = probComm; } public StudentFormViewModel(IProbCommRepository pRepository) { probCommRepository = pRepository; } } When I go to the Students Detail Page this runs: public ActionResult Details(string id) { StudentFormViewModel viewdata = new StudentFormViewModel(studentRepository.GetStudent(id), probCommRepository.FindAllProblemComms(id)); if (viewdata == null) return View("NotFound"); else return View(viewdata); } The GetStudent works fine and returns an instance of the student to output on the page, below the student I output all problems logged against them, but underneath these problems I want to show the communications related to the Problem. The LINQ I am using for ProbComms is This is located in the Model class ProbCommRepository, and accessed via a IProbCommRepository interface: public IQueryable<ProbComm> FindAllProblemComms(string studentEmail) { return (from p in db.ProbComms where p.Problem.StudentEmail.Equals(studentEmail) orderby p.Problem.ProblemDateTime select p); } However for example if I have this data in the ProbComms table: ProblemID CommunicationID 1 1 1 2 The query returns two rows so I assume I somehow have to groupby Problem or ProblemID but I am not too sure how to do this with the way I have built things as the return type has to be ProbComm for the query as thats what Model class its located in. When it comes to the view the Details.aspx calls two partial views each passing the relevant view data through, StudentDetails works fine page: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MitigatingCircumstances.Controllers.StudentFormViewModel>" %> <% Html.RenderPartial("StudentDetails", this.ViewData.Model.Student); %> <% Html.RenderPartial("StudentProblems", this.ViewData.Model.ProbComm); %> StudentProblems uses a foreach loop to loop through records in the Model and I am trying another foreach loop to output the communication details: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<MitigatingCircumstances.Models.ProbComm>>" %> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle( function() { $(this).parent().next("div.Content").show("slow"); $(this).attr("class", "ArrowClose"); }, function() { $(this).parent().next("div.Content").hide("slow"); $(this).attr("class", "ArrowExpand"); }); }); </script> <div class="studentProblems"> <% var i = 0; foreach (var item in Model) { %> <div id="ContainerPanel<%= i = i + 1 %>" class="ContainerPanel"> <div id="header<%= i = i + 1 %>" class="collapsePanelHeader"> <div id="dvHeaderText<%= i = i + 1 %>" class="HeaderContent"><%= Html.Encode(String.Format("{0:dd/MM/yyyy}", item.Problem.ProblemDateTime))%></div> <div id="dvArrow<%= i = i + 1 %>" class="ArrowExpand"></div> </div> <div id="dvContent<%= i = i + 1 %>" class="Content" style="display: none"> <p> Type: <%= Html.Encode(item.Problem.CommunicationType.TypeName) %> </p> <p> Problem Outline: <%= Html.Encode(item.Problem.ProblemOutline)%> </p> <p> Mitigating Circumstance Form: <%= Html.Encode(item.Problem.MCF)%> </p> <p> Mitigating Circumstance Level: <%= Html.Encode(item.Problem.MitigatingCircumstanceLevel.MCLevel)%> </p> <p> Absent From: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentFrom))%> </p> <p> Absent Until: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentUntil))%> </p> <p> Requested Follow Up: <%= Html.Encode(String.Format("{0:g}", item.Problem.RequestedFollowUp))%> </p> <p>Problem Communications</p> <% foreach (var comm in Model) { %> <p> <% if (item.Problem.ProblemID == comm.ProblemID) { %> <%= Html.Encode(comm.ProblemCommunication.CommunicationOutline)%> <% } %> </p> <% } %> </div> </div> <br /> <% } %> </div> The issue is that using the example data before the Model has two records for the same problem as there are two communications for that problem, therefore duplicating the output. Any help with this would be gratefully appreciated. Thanks, Jon

  • Visual Studio Add in to Add Tracing

    - by Eric Brown - Cal
    I was looking to write/get a visual studio addin. I want to be able to write descriptive log calls at the top and bottom of a function. like this log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - in"); log.debug("TheClass.TheMethod(string TheStringParam ="+TheStringParam+") - out"); Is there an adin that does this? Is there source anywhere for an add in like Ghost Doc that does reflection(or whatever) to parse the parameters and such?

  • Python mechanize to follow image links?

    - by Shark
    mechanize's Browser class is great and it's follow_link() function is great too. But what to do with this kind of links: <a href="http://example.com"><img src="…"></a> Is there any way to follow such links? The text attribute of this type of links is simply '[IMG]', so AFAIK, there is no way to differentiate such links. Any help would be appreciated.

  • the easiest way to convert matrix to one row vector

    - by niko
    Hi, Does anyone know what is the best way to create one row matrix (vector) from M x N matrix by putting all rows, from 1 to M, of the original matrix into first row of new matrix the following way: A = [row1; row2, ..., rowM] B = [row1, row2, ..., rowM] Example: A = [1 1 0 0; 0 1 0 1] B = [1 1 0 0 0 1 0 1] I would be very thankful if anyone suggested any simple method or perhaps points out a function if it already exists that could generate matrix B from original matrix A.

  • JS/Jquery, Match not finding the PNG = match('/gif|jpg|jpeg|png/')

    - by nobosh
    I have the following code which I use to match fancybox possible elements: $('a.grouped_elements').each(function(){ var elem = $(this); // Convert everything to lower case to match smart if(elem.attr('href').toLowerCase().match('/gif|jpg|jpeg|png/') != null) { elem.fancybox(); } }); It works great with JPGs but it isn't matching PNGs for some reason. Anyone see a bug with the code? Thanks

  • Set different line format for a graph with more than one serie with pChart

    - by woodgate
    I am actually using the pChart PHP library for generate graphs. I wanna know if it's possible to give a different line format for a graph with multiple series. I need a line with for example 3px of width but other line with 1px of width. Is that possible? In the official documentation only appears a function that give format to the lines of all series: http://pchart.sourceforge.net/documentation.php?topic=pChart#setLineStyle Thanks a lot.

  • Overloading *(iterator + n) and *(n + iterator) in a C++ iterator class?

    - by exscape
    (Note: I'm writing this project for learning only; comments about it being redundant are... uh, redundant. ;) I'm trying to implement a random access iterator, but I've found very little literature on the subject, so I'm going by trial and error combined with Wikpedias list of operator overload prototypes. It's worked well enough so far, but I've hit a snag. Code such as exscape::string::iterator i = string_instance.begin(); std::cout << *i << std::endl; works, and prints the first character of the string. However, *(i + 1) doesn't work, and neither does *(1 + i). My full implementation would obviously be a bit too much, but here's the gist of it: namespace exscape { class string { friend class iterator; ... public: class iterator : public std::iterator<std::random_access_iterator_tag, char> { ... char &operator*(void) { return *p; // After some bounds checking } char *operator->(void) { return p; } char &operator[](const int offset) { return *(p + offset); // After some bounds checking } iterator &operator+=(const int offset) { p += offset; return *this; } const iterator operator+(const int offset) { iterator out (*this); out += offset; return out; } }; }; } int main() { exscape::string s = "ABCDEF"; exscape::string::iterator i = s.begin(); std::cout << *(i + 2) << std::endl; } The above fails with (line 632 is, of course, the *(i + 2) line): string.cpp: In function ‘int main()’: string.cpp:632: error: no match for ‘operator*’ in ‘*exscape::string::iterator::operator+(int)(2)’ string.cpp:105: note: candidates are: char& exscape::string::iterator::operator*() *(2 + i) fails with: string.cpp: In function ‘int main()’: string.cpp:632: error: no match for ‘operator+’ in ‘2 + i’ string.cpp:434: note: candidates are: exscape::string exscape::operator+(const char*, const exscape::string&) My guess is that I need to do some more overloading, but I'm not sure what operator I'm missing.

  • Casting functions -- Is it a code smell?

    - by Earlz
    I recently began to start using functions to make casting easier on my fingers for one instance I had something like this ((Dictionary<string,string>)value).Add(foo); and converted it to a tiny little helper function so I can do this ToDictionary(value).Add(foo); Is this a code smell? (also I've marked this language agnostic even though my example is C#)

  • Using SimpleModal with jstestdriver?

    - by leeand00
    Hello, I'm using simpleModal to display a dialog, and I want to be able to tell if it has been displayed or not using jstestdriver. In my browser when I display the dialog it sets the className to "simplemodal-data" on the id of the content I'm displaying, but when I do the same thing in jstestdriver it's like the .modal() function doesn't even do anything. Is there something I'm missing here? Also see this related thread.
