  • Model binding difficulty

    - by user281180
    I am having a model and I am using ajax.post. I can see that the model binding isn`t being done for the arraylists in my model, though binding done for the properties of int or string type. Why is that so? My code is as below. I have a model with the following properties public class ProjectModel { public int ID { get; set; } public ArrayList Boys= new ArrayList(); } In my view I have $(document).ready(function () { var project = new Object(); var Boys= new Array(); var ID; ....... ID = $('#ID').val(); project.Boys= Boys; ..... $.ajax({ type: "POST", url: '<%=Url.Action("Create","Project") %>', data: JSON.stringify(project), contentType: "application/json; charset=utf-8", dataType: "html", success: function () { }, error: function (request, status, error) { } }); // My controller [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(ProjectModel project) { try { project.CreateProject(); return RedirectToAction("Index"); } ....

  • How to identify multiple identical pairs in two vectors

    - by Sacha Epskamp
    In my graph-package (as in graph theory, nodes connected by edges) I have a vector indicating for each edge the node of origin from, a vector indicating for each edge the node of destination to and a vector indicating the curve of each edge curve. By default I want edges to have a curve of 0 if there is only one edge between two nodes and curve of 0.2 if there are two edges between two nodes. The code that I use now is a for-loop, and it is kinda slow: curve <- rep(0,5) from<-c(1,2,3,3,2) to<-c(2,3,4,2,1) for (i in 1:length(from)) { if (any(from==to[i] & to==from[i])) { curve[i]=0.2 } } So basically I look for each edge (one index in from and one in to) if there is any other pair in from and to that use the same nodes (numbers). What I am looking for are two things: A way to identify if there is any pair of nodes that have two edges between them (so I can omit the loop if not) A way to speed up this loop # EDIT: To make this abit clearer, another example: from <- c(4L, 6L, 7L, 8L, 1L, 9L, 5L, 1L, 2L, 1L, 10L, 2L, 6L, 7L, 10L, 4L, 9L) to <- c(1L, 1L, 1L, 2L, 3L, 3L, 4L, 5L, 6L, 7L, 7L, 8L, 8L, 8L, 8L, 10L, 10L) cbind(from,to) from to [1,] 4 1 [2,] 6 1 [3,] 7 1 [4,] 8 2 [5,] 1 3 [6,] 9 3 [7,] 5 4 [8,] 1 5 [9,] 2 6 [10,] 1 7 [11,] 10 7 [12,] 2 8 [13,] 6 8 [14,] 7 8 [15,] 10 8 [16,] 4 10 [17,] 9 10 In these two vectors, pair 3 is identical to pair 10 (both 1 and 7 in different orders) and pairs 4 and 12 are identical (both 2 and 8). So I would want curve to become: [1,] 0.0 [2,] 0.0 [3,] 0.2 [4,] 0.2 [5,] 0.0 [6,] 0.0 [7,] 0.0 [8,] 0.0 [9,] 0.0 [10,] 0.2 [11,] 0.0 [12,] 0.2 [13,] 0.0 [14,] 0.0 [15,] 0.0 [16,] 0.0 [17,] 0.0 (as I vector, I transposed twice to get row numbers).

  • Generic applet style system for publishing mathematics demonstrations?

    - by Alex
    Anyone who's tried to study mathematics using online resources will have come across these Java applets that demonstrate a particular mathematical idea. Examples: http://www.math.ucla.edu/~tao/java/Mobius.html http://www.mathcs.org/java/programs/FFT/index.html I love the idea of this interactive approach because I believe it is very helpful in conveying mathematical principles. I'd like to create a system for visually designing and publishing these 'mathlets' such that they can be created by teachers with little programming experience. So in order to create this app, i'll need a GUI and a 'math engine'. I'll probably be working with .NET because thats what I know best and i'd like to start experimenting with F#. Silverlight appeals to me as a presentation framework for this project (im not worried about interoperability right now). So my questions are: does anything like this exist already in full form? are there any GUI frameworks for displaying mathematical objects such as graphs & equations? are there decent open source libraries that exposes a mathematical framework (Math.NET looks good, just wondering if there is anything else out there) is there any existing work on taking mathematical models/demos built with maple/matlab/octave/mathematica etc and publishing them to the web?

  • Java: over-typed structures?

    - by HH
    Term over-type structure = a data structure that accepts different types, can be primitive or user-defined. I think ruby supports many types in structures such as tables. I tried a table with types 'String', 'char' and 'File' in Java but errs. How can I have over-typed structure in Java? How to show types in declaration? What about in initilization? Suppose a structure: INDEX VAR FILETYPE //0 -> file FILE //1 -> lineMap SizeSequence //2 -> type char //3 -> binary boolean //4 -> name String //5 -> path String Code import java.io.*; import java.util.*; public class Object { public static void print(char a) { System.out.println(a); } public static void print(String s) { System.out.println(s); } public static void main(String[] args) { Object[] d = new Object[6]; d[0] = new File("."); d[2] = 'T'; d[4] = "."; print(d[2]); print(d[4]); } } Errors Object.java:18: incompatible types found : java.io.File required: Object d[0] = new File("."); ^ Object.java:19: incompatible types found : char required: Object d[2] = 'T'; ^

  • JPA - Can an @JoinColumn be an @Id as well? SerializationException occurs.

    - by Shivago
    Hi everyone, I am trying to use an @JoinColumn as an @Id using JPA and I am getting SerializationExceptions, "Could not serialize." UserRole.java: @Entity @Table(name = "authorities") public class UserRole implements Serializable { @Column(name = "authority") private String role; @Id @ManyToOne @JoinColumn(name = "username") private User owner; ... } User.java: @Entity @Table(name = "users") public class User implements Serializable { @Id @GeneratedValue protected Long id; @Column(name = "username") protected String email; @OneToMany(mappedBy = "owner", fetch = FetchType.LAZY, cascade = CascadeType.ALL) protected Set<UserRole> roles = new HashSet<UserRole>(); .... } "username" is set up as a unique index in my Users table but not as the primary key. Is there any way to make "username" act as the ID for UserRole? I don't want to introduce a numeric key in UserRole. Have I totally lost the plot here? I am using MySQL and Hibernate under the hood.

  • Codeigniter PHP - loading a view at an anchor point

    - by James Billings
    I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.

  • Python lists/arrays: disable negative indexing wrap-around

    - by wim
    While I find the negative number wraparound (i.e. A[-2] indexing the second-to-last element) extremely useful in many cases, there are often use cases I come across where it is more of an annoyance than helpful, and I find myself wishing for an alternate syntax to use when I would rather disable that particular behaviour. Here is a canned 2D example below, but I have had the same peeve a few times with other data structures and in other numbers of dimensions. import numpy as np A = np.random.randint(0, 2, (5, 10)) def foo(i, j, r=2): '''sum of neighbours within r steps of A[i,j]''' return A[i-r:i+r+1, j-r:j+r+1].sum() In the slice above I would rather that any negative number to the slice would be treated the same as None is, rather than wrapping to the other end of the array. Because of the wrapping, the otherwise nice implementation above gives incorrect results at boundary conditions and requires some sort of patch like: def ugly_foo(i, j, r=2): def thing(n): return None if n < 0 else n return A[thing(i-r):i+r+1, thing(j-r):j+r+1].sum() I have also tried zero-padding the array or list, but it is still inelegant (requires adjusting the lookup locations indices accordingly) and inefficient (requires copying the array). Am I missing some standard trick or elegant solution for slicing like this? I noticed that python and numpy already handle the case where you specify too large a number nicely - that is, if the index is greater than the shape of the array it behaves the same as if it were None.

  • Django: Create custom template tag -> ImportError

    - by Alexander Scholz
    I'm sorry to ask this again, but I tried several solutions from stack overflow and some tutorials and I couldn't create a custom template tag yet. All I get is ImportError: No module named test_tag when I try to start the server via python manage.py runserver. I created a very basic template tag (found here: django templatetag?) like so: My folder structure: demo manage.py test __init__.py settings.py urls.py ... templatetags __init__.py test_tag.py test_tag.py: from django import template register = template.Library() @register.simple_tag def test_tag(input): if "foo" == input: return "foo" if "bar" == input: return "bar" if "baz" == input: return "baz" return "" index.html: {% load test_tag %} <html> <head> ... </head> <body> {% cms_toolbar %} {% foobarbaz "bar" %} {% foobarbaz "elephant" %} {% foobarbaz "foo" %} </body> </html> and my settings.py: INSTALLED_APPS = ( ... 'test_tag', ... ) Please let me know if you need further information from my settings.py and what I did wrong so I can't even start my server. (If I delete 'test_tag' from installed apps I can start the server but I get the error that test_tag is not known, of course). Thanks

  • Is it possible to return a list of numbers from a Sybase function?

    - by ps_rs4
    I'm trying to overcome a very serious performance issue in which Sybase refuses to use the primary key index on a large table because one of the required fields is specified indirectly through another table - or, in other words; SELECT ... FROM BIGTABLE WHERE KFIELD = 123 runs in ms but SELECT ... FROM BIGTABLE, LTLTBL WHERE KFIELD = LTLTBL.LOOKUP AND LTLTBL.UNIQUEID = 'STRINGREPOF123' takes 30 - 40 seconds. I've managed to work around this first problem by using a function that basically lets me do this; SELECT ... FROM BIGTABLE WHERE KFIELD = MYFUNC('STRINGREPOF123') which also runs in ms. The problem, however, is that this approach only works when there is a single value returned by MYFUNCT but I have some cases where it may return 2 or 3 values. I know that the SQL SELECT ... FROM BIGTABLE WHERE KFIELD IN (123,456,789) also returns in millis so I'd like to have a function that returns a list of possible values rather than just a single one - is this possible? Sadly the application is running on Sybase ASA 9. Yes I know it is old and is scheduled to be refreshed but there's nothing I can do about it now so I need logic that will work with this version of the DB. Thanks in advance for any assistance on this matter.

  • C++, Ifstream opens local file but not file on HTTP Server

    - by fammi
    Hi, I am using ifstream to open a file and then read from it. My program works fine when i give location of the local file on my system. for eg /root/Desktop/abc.xxx works fine But once the location is on the http server the file fails to open. for eg http://192.168.0.10/abc.xxx fails to open. Is there any alternate for ifstream when using a URL address? thanks. part of the code where having problem: bool readTillEof = (endIndex == -1) ? true : false; // Open the file in binary mode and seek to the end to determine file size ifstream file ( fileName.c_str ( ), ios::in|ios::ate|ios::binary ); if ( file.is_open ( ) ) { long size = (long) file.tellg ( ); long numBytesRead; if ( readTillEof ) { numBytesRead = size - startIndex; } else { numBytesRead = endIndex - startIndex + 1; } // Allocate a new buffer ptr to read in the file data BufferSptr buf (new Buffer ( numBytesRead ) ); mpStreamingClientEngine->SetResponseBuffer ( nextRequest, buf ); // Seek to the start index of the byte range // and read the data file.seekg ( startIndex, ios::beg ); file.read ( (char *)buf->GetData(), numBytesRead ); // Pass on the data to the SCE // and signal completion of request mpStreamingClientEngine->HandleDataReceived( nextRequest, numBytesRead); mpStreamingClientEngine->MarkRequestCompleted( nextRequest ); // Close the file file.close ( ); } else { // Report error to the Streaming Client Engine // as unable to open file AHS_ERROR ( ConnectionManager, " Error while opening file \"%s\"\n", fileName.c_str ( ) ); mpStreamingClientEngine->HandleRequestFailed( nextRequest, CONNECTION_FAILED ); } }

  • global variables doesn't change value in Javascript

    - by user1856906
    My project is composed by 2 html pages: 1)index.html, wich contains the login and the registration form. 2)user_logged.html, wich contains all the features of a logged user. Now, what I want to do is a control if the user is really logged, to avoid the case where a user paste a url in the browser and can see the pages of another user. hours as now, if a user paste this url in the browser: www.user_loggato.html?user=x#profile is as if logged in as user x and this is not nice. My html pages both use js files that contains scripts. I decided to create a global variable called logged inizialized to false and change the variable to true when the login is succesfull. The problem is that the variable, remains false. here is the code: var logged=false; (write in the file a.js) while in the file b.js I have: function login() { //if succesfull logged=true; window.location.href = "user_loggato.html?user="+ JSON.parse(str).username + #profilo"; Now with some alerts I found that my variable logged is always false. Why? if I have not explained well or if there is not some information in order to respond to my question let me know.

  • JQuery: Combine multiple pages into one

    - by k_wave
    I am developing an application by using phonegap and jQuery Mobile. Phonegap recommends a single document structure. As 5 divs or more in a document are pretty unclear, I'm trying to split up my pages (the div's) into multiple documents. As soon as phonegap loads the app, I want to insert these documents into the index.html. function loadPage(external_document) { var docname=external_document+".html"; $.get(docname, function(data) { console.log(docname+" loading"); $("body").append($(data).find("body")); $("head").append($(data).find("head")); console.log(docname+" loaded"); }); } document.addEventListener("deviceready", function(){ loadPage("DialogCredentials"); }, false); DialogCredentials.html <html> <head> <script type="text/javascript" src="js/DialogCredentials.js"></script> </head> <body> <div data-role="page" id="dlg_credentials"> <div data-role="header"><h1>Login</h1></div> <div data-role="content"> ... </div> </div><!-- /page --> </body> </html> As soon as the loadPage gets executed there should be a <div id="dlg_credentials"… and the corresponding javascript tag in the dom of my main document. But it isn't. There are no errors shown in the web inspector. So what am I doing wrong here?

  • How add logic to Views? Ruby on Rails

    - by Gotjosh
    Right now I'm building a project management app in rails, here is some background info: Right now i have 2 models, one is User and the other one is Client. Clients and Users have a one-to-one relationship (client - has_one and user - belongs_to which means that the foreign key it's in the users table) So what I'm trying to do it's once you add a client you can actually add credentials (add an user) to that client, in order to do so all the clients are being displayed with a link next to that client's name meaning that you can actually create credentials for that client. What i can't figure it out how to do is, that if you actually have credentials in the database (meaning that there's a record in the users table with your client id) then don't display that link. Here's what i thought that would work <% for client in @client%> <h5> <h4><%= client.id %></h4> <a href="/clients/<%= client.id %>"><%= client.name %></a> <% for user in @user %> <% if user.client_id = client.id %> <a href="/clients/<%= client.id %>/user/new">Credentials</a> <%end%> <% end %> </h5> <% end %> And here's the controller: def index @client = Client.find_all_by_admin(0) @user = User.find(:all) end but instead it just puts the link the amount of times per records in the user table. Any help?

  • My fade in goes to all opaque for it goes to transparent

    - by DerNalia
    So, I'm trying to fade in a transparent div, kinda like hulu does when you click dim lights... here is what i have: //show the bg new Effect.Appear('darkBackgroundLayer', {duration: 0.3}); then when my pop up is initialized // create the div for background dimming if($('darkBackgroundLayer')){ Element.remove('darkBackgroundLayer') } var transparentBG = document.createElement('div'); transparentBG.className = 'darkenBackground'; transparentBG.id = "darkBackgroundLayer" transparentBG.style.display = "none"; document.body.appendChild(transparentBG); and the CSS for the new div .darkenBackground { background-color: rgb(0, 0, 0); opacity: 0.7; /* Safari, Opera */ -moz-opacity:0.70; /* FireFox */ filter: alpha(opacity=70); /* IE */ z-index: 20; height: 100%; width: 100%; background-repeat:repeat; position:fixed; top: 0px; left: 0px; } but, currently, it fades in... all the way to a solid back, then jumps to the .7 opacity... ideas?

  • Creating a floating button

    - by Robert Smith
    Hey all, I'm working on a Firefox extension and am out of ideas on how to implement a floating button. I need a button that is overlayed on my page that I can show/hide and dynamically position just about anywhere on my page. I thought I could do something like a fancy CSS tool-tip except replace it with button functionality, but that idea failed because I couldn't pull my example apart well enough to understand what all I need to include, need to change, etc. I've thought about using jQuery(though wouldn't mind avoiding, unless it makes this painfully easy) but will be looking more into that as a possibility now. If anyone can offer a tutorial link, ideas, sample code, anything to help get me moving in the right direction I will greatly appreciate it! Thanks! Edit: Clarification I'm not entirely sure how to actually create the overlayed button. I tried to create a a floating div with some text in it, and nothing showed up, but I got no errors, which means I'm doing something wrong, but I have no idea what that is. http://www.fijiwebdesign.com/blog/css-tooltips-floating-html-elements.html If you take a look at that webpage you see that there is that floating "feedback" button, I would like to create something similar, only it wouldn't be anchored to the sides, but I could position it over text, etc. #floatingBtn { position: absolute; z-index: 10000; top: 50%; left: 50%; } Thats the CSS I used to try and float my div. I don't know if I'm creating the div in the wrong place or... I thought if I could get a floating div with some text, I could turn that into my button.

    Hello friends, I have a JSP page on which I have a div tag in which there is a a IMG tag. Using this IMG tag I want to show an image in it. Here the source path of an image is comes from database so I assigned a JSP variable using JSP scriplet. This JSP variable have the source path of an image. This path of image may be of different machine or of same machine i.e. images are stored on different machine or on same machine i.e. on local machine on different drive. The problem is that how to give path of image stored on different machine as well as on same machine. I have tried different ways like by giving ip address of that machine. Here is the path that of local machine where the image is stored img src= file:\localhost\D:\ScannedSheets\testproj/batch1/IMG001.jpg style="z-index:1; position:absolute; top:0; left:0; width:850; height:1099" With this syntax the image is visible in Internet Explorer but With the same syntax Its not visible in FireFox, Google Chrome etc. Please Guide me in friends.

  • Login fails when recreating database with Code First

    - by Mun
    I'm using ASP.NET Entity Framework's Code First to create my database from the model, and the login seems to fail when the database needs to be recreated after the model changes. In Global.asax, I've got the following: protected void Application_Start() { Database.SetInitializer(new DropCreateDatabaseIfModelChanges<EntriesContext>()); // ... } In my controller, I've got the following: public ActionResult Index() { // This is just to force the database to be created var context = new EntriesContext(); var all = (from e in context.Entries select e).ToList(); } When the database doesn't exist, it is created with no problems. However, when I make a change to the model, rebuild and refresh, I get the following error: Login failed for user 'sa'. My connection string looks like this: <add name="EntriesContext" connectionString="Server=(LOCAL);Database=MyDB;User Id=sa;Password=password" providerName="System.Data.SqlClient" /> The login definitely works as I can connect to the server and the database from Management Studio using these credentials. If I delete the database manually, everything works correctly and the database is recreated as expected with the schema reflecting the changes made to the model. It seems like either the password or access to the database is being lost. Is there something else I need to do to get this working?

  • Detectig by how much user has scrolled

    - by Sean
    I have an image pop-up ability on my website (see this screenshot), in order to show users the full resolution picture when they click on a smaller version on the page. This is the current CSS that positions it: div#enlargedImgWrapper { position: absolute; top: 30px; left: 55px; z-index: 999; } The problem now is that if I click on an image further down the page, the window still appears in the top left corner of the page, where I can't see it until I scroll back up. I need it to appear relative to the window, whatever its current position relative to the document is. Note: I don't want to use position: fixed; as some images might be taller than the screen, so I want users to be able to scroll along the image as well. My idea was to use JS to change the top value: var scrollValue = ???; document.getElementById('enlargedImgWrapper').style.top = scrollValue+30 + 'px'; How can I detect by how much the user has scrolled down the page (var scrollValue)? Or is there a 'better' way to do this? Thanks!

  • button onclick not working

    - by nsw1475
    I have a javascript where I need to hide (and eventually show) some text by clicking a button. However, when I click the button, it does not call the function specified in the onclick parameter, and so nothing happens. Here is my source code: <script type="text/javascript"> $(document).ready(function(){ var tip = 1; $(".tip1").hide(); $(".tip2").hide(); switch (tip) { case 1: $(".tip1").show(); break; case 2: $(".tip2").show(); break; } function nextTip() { $(".tip1").hide(); return; } }); </script> <br/> <div id='bg_container' style='background-image: url("<?=$PICS?>trackingpage_middle.jpg")' > <img style='z-index:-1;' width='737px' src='<?=$PICS?>trackingpage_top.jpg'> <div id='main_container' > <form> <input type="button" onClick="nextTip()" value = "Next Tip" /> </form> <div class="tip1"> ... and so on.

  • Asynchronous javascript issue

    - by amit
    I am trying to create a function which takes values from various html elements of the page to create a string and pass on to a variable. now this works great for all browsers except IE 8 and 9. IE tends to skip the part of fetching the values and goes straight to the variable and finds nothing.. is there a way to sync it all so that it works in IE? function seturl() { var qstring = returnQString(); $('span.keyword').text($.trim($('#hdnKeyWord').attr('value'))); $('input.search_box').attr('value', $.trim($('#hdnKeyWord').attr('value'))); $('#hdnSearchKeyword').attr('value', $.trim($('#hdnKeyWord').attr('value'))); $(".search_box").val($.trim($("#hdn_span_hdnKeyWord").text())); $(".header_inner input[type='text']").focus(); $(".search_term input[type='text']").focus(); $('#locationurl').attr('value', qstring); } function returnQString(){ var qstring = $.trim($('#locationurl').attr('init')); //initial value of the url qstring += "?type=" + $('#hdnSTSearch').attr('value'); // type of handler hit qstring += "&keyword=" + encodeURIComponent($('#hdnKeyWord').attr('value')); // keyword addition qstring += "&pagestart=" + $('#current_page').attr('value'); // pagestart(current page) addition qstring += "&pagesize=" + $('#show_per_page').attr('value'); // per page size addition qstring += "&facets=" // facetsearch $.each(selectedFilter.items, function (index, value) { qstring += value.filter + ","; }); qstring += "&selectedSection=" + selectedSection // Section Select return qstring; }

  • Get context for search string in text in C#

    - by soundslike
    Given a string text which contains newline there is a search keyword which matches an item within the text. How do I implement the following in C#: searchIdx = search index (starting with 0, then 1, etc. for each successive call to GetSearchContext. Initially start with 0. contextsTxt = string data to search in searchTxt = keyword to search for in contextsTxt numLines = number of lines to return surrounding the searchTxt found (ie. 1 = the line the searchTxt is found on, 2 = the line the searchTxt is found on, 3 = the line above the searchTxt is found on, the line the searchTxt is found on, and the line below the searchTxt is found on) returns the "context" based on the parameters string GetSearchContext(int searchIdx, string contentsTxt, string searchTxt, int numLines); If there's a better function interface to accomplish this feel free to suggest that as well. I tried the following but doesn't seem to work properly all the time: private string GetSearchContext(string contentValue, string search, int numLines) { int searchIdx = contentValue.IndexOf(search); int startIdx = 0; int lastIdx = 0; while (startIdx != -1 && (startIdx = contentValue.IndexOf('\n', startIdx+1)) < searchIdx) { lastIdx = startIdx; } startIdx = lastIdx; if (startIdx < 0) startIdx = 0; int endIdx = searchIdx; int lineCnt = 0; while (endIdx != -1 && lineCnt++ < numLines) { endIdx = contentValue.IndexOf('\n', endIdx + 1); } if (endIdx == -1 || endIdx > contentValue.Length - 1) endIdx = contentValue.Length - 1; string lines = contentValue.Substring(startIdx, endIdx - startIdx + 1); if (lines[0] == '\n') lines = lines.Substring(1); if (lines[lines.Length - 1] == '\n') { lines = lines.Substring(0, lines.Length - 1); } if (lines[lines.Length - 1] == '\r') { lines = lines.Substring(0, lines.Length - 1); } return lines; }

  • crash when using stl vector at instead of operator[]

    - by Jamie Cook
    I have a method as follows (from a class than implements TBB task interface - not currently multithreading though) My problem is that two ways of accessing a vector are causing quite different behaviour - one works and the other causes the entire program to bomb out quite spectacularly (this is a plugin and normally a crash will be caught by the host - but this one takes out the host program as well! As I said quite spectacular) void PtBranchAndBoundIterationOriginRunner::runOrigin(int origin, int time) const // NOTE: const method { BOOST_FOREACH(int accessMode, m_props->GetAccessModes()) { // get a const reference to appropriate vector from member variable // map<int, vector<double>> m_rowTotalsByAccessMode; const vector<double>& rowTotalsForAccessMode = m_rowTotalsByAccessMode.find(accessMode)->second; if (origin != 129) continue; // Additional debug constrain: I know that the vector only has one non-zero element at index 129 m_job->Write("size: " + ToString(rowTotalsForAccessMode.size())); try { // check for early return... i.e. nothing to do for this origin if (!rowTotalsForAccessMode[origin]) continue; // <- this works if (!rowTotalsForAccessMode.at(origin)) continue; // <- this crashes } catch (...) { m_job->Write("Caught an exception"); // but its not an exception } // do some other stuff } } I hate not putting in well defined questions but at the moment my best phrasing is : "WTF?" I'm compiling this with Intel C++ 11.0.074 [IA-32] using Microsoft (R) Visual Studio Version 9.0.21022.8 and my implementation of vector has const_reference operator[](size_type _Pos) const { // subscript nonmutable sequence #if _HAS_ITERATOR_DEBUGGING if (size() <= _Pos) { _DEBUG_ERROR("vector subscript out of range"); _SCL_SECURE_OUT_OF_RANGE; } #endif /* _HAS_ITERATOR_DEBUGGING */ _SCL_SECURE_VALIDATE_RANGE(_Pos < size()); return (*(_Myfirst + _Pos)); } (Iterator debugging is off - I'm pretty sure) and const_reference at(size_type _Pos) const { // subscript nonmutable sequence with checking if (size() <= _Pos) _Xran(); return (*(begin() + _Pos)); } So the only difference I can see is that at calls begin instead of simply using _Myfirst - but how could that possibly be causing such a huge difference in behaviour?
