  • Struct inside a class

    - by Balakrishnan
    I have a class definition of the form class X { public: //class functions private: A_type *A; //other class variables }; and struct A_type is defined as struct A_type { string s1,s2,s3; }; Inside the constructor, I allocate appropriate memory for A and try A[0].s1="somestring"; It shows segmentation fault. Is this kind of declaration invalid, or am I missing something

  • What hash/map based programming language exist?

    - by Davorak
    Much like lisp is often considered a list based programming language what languages are considered map based? I remember reading about one a few years back, but can not longer find a reference to it. It looked something like: [if:test then:<code> else:<more code>] edit: and more where quoted code blocks which would be conditional evaluated. In this fashion if/cond and others would not be special form as they are in lisp/scheme.

  • How to layer if statements when order of logic is irrelevant?

    - by jimmyjimmy
    Basically I have a series of logic in my website that can lead to 5 total outcomes. Basically two different if tests and then a catch all else statement. For example: if cond1: if mod1: #do things elif mod2: #do things elif cond2: if mod1: #do things elif mod2 #do things else: #do things I was thinking about rewriting it like this: if cond1 and mod1: #do things elif cond1 and mod2: #do things elif cond2 and mod1: #do things elif cond2 and mod2: #do things else: #do things Is there any real difference in these two coding options/a better choice for this kind of logic testing?

  • How do I install OSQA with limited access to the server?

    - by Noir
    I would very much like to install OSQA on my host (provided/owned by my friend), but I can not make heads or tails of how I would go about doing it; a lot of the dependancies and such can't be installed with the current level of access (or most probably just knowledge) that I have. I can provide any further information required, and attempt to contact (friend) to see if he can do any of it for me, but I'm unsure as to how often I will be able to contact him. exec and shell_exec are not disabled on the server. If there are any other alternatives that I could use, please let me know! I tried Qwench but that was pretty buggy. I can usually deal with these kind of things, but this is my first foray into Python stuff!

  • Problems with MVC Ajax.ActionLink and returning a PartialView

    - by mwright
    I'm trying to implement a simple Ajax update using MVC and have run into an issue. My understanding of how to implement Ajax with MVC is to use an Ajax.ActionLink which allows the content to be updated based on user interaction. I have an Ajax.ActionLink that looks like the following: <%= Ajax.ActionLink("Call Ajax", "Ajax", new AjaxOptions{UpdateTargetId = "updateDiv"}) %> If, in the controller, I return a string it works fine. However, when returning a PartialView instead, nothing happens. I can step through and verify that the controller is "returning" the partial view but nothing shows up in what I'm calling the updateDiv. How can I go about determining what the problem is?

  • ASP.NET MVC Populating a DropDownList with a value from the view

    - by lomaxx
    In my controller I have this: ViewData["maskList"] = new SelectList(equipmentRepository.GetMasks(), "Id", "DisplayName"); and then I bind it to my view using <div each="var nfa in mfa.NasalFittingAssessment"> ${Html.DropDownList("NasalMaskTypeId", ViewData["maskList"] as IEnumerable<System.Web.Mvc.SelectListItem>, new { class = "ddl" })} </div> Note that I'm using the spark view engine so this DropDownList is getting rendered to the page via a loop. This means that the selected value of the dropdown list will change on each iteration of the loop. What I can't work out is how to pass in the value I want to set the DropDownList to based on the value that is currently being rendered to the screen.

  • Windows 7 file-based backup service

    - by Ben Voigt
    I'm looking for a good replacement for Lazy Mirror, since it doesn't support Windows 7 well. Pros: One of the things I really loved about Lazy Mirror is that it always maintains a "full" backup, but does so by only copying modified files. As each file was copied, the old version got archived (moved to an out-of-the-way location). So after mirroring ran, there'd be a complete copy of the file system, which could even be booted if necessary. At the same time, extra space on the backup media was used to store as many older versions of files as possible, without wasting space storing multiple copies of the same version. It seems that with Windows 7 backup, there'd be wasted space storing the same data in both the system image and file backup. It was completely file-based, but also aware of the registry (it had a feature to dump the live registry to hive files in the correct format). The backups were normal NTFS filesystems, no special tool was needed to read them. It automatically cleaned out the oldest previous versions when space ran out (unlike Windows 7 backup which apparently simply starts failing the the backup media fills.) It copied all file attributes including security. Cons: It doesn't deal well with junction points, symbolic links, and hard links. It didn't run as a service without lots of help from firesrv or srvany, and then you couldn't interact with the GUI. Running as a service was necessary to be able to mirror protected OS files. It didn't have open file handling, except for registry hives. I guess that the file-by-file archive and replacement could leave mismatched sets of files, if the mirror was interrupted. This would be the advantage of incremental backup techniques that require old full backup + all intermediate incremental backups to restore. But I don't see this as presenting much of a problem, you'd really only have a boot failure if you had a mixture of pre- and post-service pack files, and I can run a full image backup using another tool before applying a service pack. Does anyone know of a tool that does both full-system backup and storage of old versions of files like Lazy Mirror did (without storing the same data multiple times), and also can run as a service in Windows 7? Free is best of course, but a reasonably priced paid program (e.g. It would be absolutely awesome if it also triggered a backup/mirror pass when a particular external drive was plugged in and generated popup warnings if backups hadn't been run recently)

  • How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment

    - by user69508
    (Please forgive if this is posted in an incorrect forum. We didn’t know exactly where to post it.) We have an ASP.NET Web API single page application - a browser-based app running in IIS to serve up HTML5/CSS3/JavaScript, which talks to the ASP.NET Web API endpoint only to access a database and transfer JSON data. Everything is working great in our development environment - that is, we have one Visual Studio solution with an ASP.NET Web API project and two class library projects for data access. While development and testing on development boxes, using IIS Express to a localhost:port to run the site and access the Web API, everything is fine. Now we need to move it to a production environment (and we’re having problems - or just not understanding what needs to be done). The production environment is all internal (nothing will be exposed on the public Internet). There are two domains. One domain, the corporate domain, is where all users login normally. The other domain, the process domain, contains the SQL Server instance that our app and Web API will need to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. So, I guess what they want is: corp domain (end users) <– firewall (open port 80) <– DMZ (web server running IIS) <– firewall (open port 80 or 1433????) <– process domain (IIS for Web API and SQL Server) We’re developers and don’t really understand all the networking aspects, so we’re wondering how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code (HTML5/CSS3/JavaScript/images/etc.) is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Or, does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to "http://server/appname/api/getitmes"? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? I’m sure there are other questions, but we’ll start with these. Thanks!!! (Note: the servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.)

  • Changing classes on multiple divs when selecting specific radio buttons

    - by Rob
    Hey everyone I got a javascript problem I can't seem to find a specific solution for on the web. What I want to be able to do is select one of the radio buttons and have that change the class of #home-right to either .rackmount or .shipping and add the class of .displaynone to the type of dimensions I don't want shown. <div id="home-right" class="rackmount"> <h4 class="helvneuebcn">Case Finder</h4> <div class="cta-options"> <input type="radio" value="Shipping and Storage" name="" checked> Shipping and Storage<br/> <input type="radio" value="Rackmount Enclosures" name=""> Rackmount Enclosures<br/> </div> <div class="shipping-dimensions displaynone"> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">H x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">W x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">L</span></div> </div> <div class="rackmount-dimensions"> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">U Height x </span></div> <div class="dimensions"><input type="text" class="size"><span class="helvneuemd">Rack Depth</span></div> </div> <div class="clear"></div> <input type="button" value="Submit" class="findcase"> </div>

  • Crashing when pushing a XIB based view controller onto navigation controller stack

    - by Michael
    I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine. In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view. When I try to push the controller init'd with this new XIB, the app crashes because of a missing view: SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; 2010-04-23 11:17:37.135 xxxx[1173:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but the view outlet was not set.' I've double checked everything, and tried building a clean XIB from scratch, but get the same result. I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it. Is it possible to get it working the "recommended" way? Thanks! Michael

  • Module based web project directory layout with git and symlinks

    - by karlthorwald
    I am planning my directory structure for a linux/apache/php web project like this: Only www.example.com/webroot/ will be exposed in apache www.example.com/ webroot/ index.php module1/ module2/ modules/ module1/ module1.class.php module1.js module2/ module2.class.php module2.css lib/ lib1/ lib1.class.php the modules/ and lib/ directory will only be in the php path. To make the css and js files visible in the webroot directory I am planning to use symlinks. webroot/ index.php module1/ module1.js (symlinked) module2/ module2.css (symlinked) I tried following these principles: layout by modules and libraries, not by file type and not by "public' or 'non public', index.php is an exception. This is for easier development. symlinking files that need to be public for the modules and libs to a public location, but still mirroring the layout. So the module structure is also visible in the resulting html code in the links, which might help development. How will git handle the symlinking of the single files correctly, is there something to consider? When it comes to images I will need to link directories, how to handle that with git? modules/ module3/ module3.class.php img/ img1.jpg img2.jpg img3.jpg They should be linked here: webroot/ module3/ img/ (symlinked ?) So this is a git and symlink question. But I would be interested to hear comments about the php layout, maybe you want to use the comment function for this.

  • tastypie posting and full example

    - by Justin M
    Is there a full tastypie django example site and setup available for download? I have been wrestling with wrapping my head around it all day. I have the following code. Basically, I have a POST form that is handled with ajax. When I click "submit" on my form and the ajax request runs, the call returns "POST http://192.168.1.110:8000/api/private/client_basic_info/ 404 (NOT FOUND)" I have the URL configured alright, I think. I can access http://192.168.1.110:8000/api/private/client_basic_info/?format=json just fine. Am I missing some settings or making some fundamental errors in my methods? My intent is that each user can fill out/modify one and only one "client basic information" form/model. a page: {% extends "layout-column-100.html" %} {% load uni_form_tags sekizai_tags %} {% block title %}Basic Information{% endblock %} {% block main_content %} {% addtoblock "js" %} <script language="JavaScript"> $(document).ready( function() { $('#client_basic_info_form').submit(function (e) { form = $(this) form.find('span.error-message, span.success-message').remove() form.find('.invalid').removeClass('invalid') form.find('input[type="submit"]').attr('disabled', 'disabled') e.preventDefault(); var values = {} $.each($(this).serializeArray(), function(i, field) { values[field.name] = field.value; }) $.ajax({ type: 'POST', contentType: 'application/json', data: JSON.stringify(values), dataType: 'json', processData: false, url: '/api/private/client_basic_info/', success: function(data, status, jqXHR) { form.find('input[type="submit"]') .after('<span class="success-message">Saved successfully!</span>') .removeAttr('disabled') }, error: function(jqXHR, textStatus, errorThrown) { console.log(jqXHR) console.log(textStatus) console.log(errorThrown) var errors = JSON.parse(jqXHR.responseText) for (field in errors) { var field_error = errors[field][0] $('#id_' + field).addClass('invalid') .after('<span class="error-message">'+ field_error +'</span>') } form.find('input[type="submit"]').removeAttr('disabled') } }) // end $.ajax() }) // end $('#client_basic_info_form').submit() }) // end $(document).ready() </script> {% endaddtoblock %} {% uni_form form form.helper %} {% endblock %} resources from residence.models import ClientBasicInfo from residence.forms.profiler import ClientBasicInfoForm from tastypie import fields from tastypie.resources import ModelResource from tastypie.authentication import BasicAuthentication from tastypie.authorization import DjangoAuthorization, Authorization from tastypie.validation import FormValidation from tastypie.resources import ModelResource, ALL, ALL_WITH_RELATIONS from django.core.urlresolvers import reverse from django.contrib.auth.models import User class UserResource(ModelResource): class Meta: queryset = User.objects.all() resource_name = 'user' fields = ['username'] filtering = { 'username': ALL, } include_resource_uri = False authentication = BasicAuthentication() authorization = DjangoAuthorization() def dehydrate(self, bundle): forms_incomplete = [] if ClientBasicInfo.objects.filter(user=bundle.request.user).count() < 1: forms_incomplete.append({'name': 'Basic Information', 'url': reverse('client_basic_info')}) bundle.data['forms_incomplete'] = forms_incomplete return bundle class ClientBasicInfoResource(ModelResource): user = fields.ForeignKey(UserResource, 'user') class Meta: authentication = BasicAuthentication() authorization = DjangoAuthorization() include_resource_uri = False queryset = ClientBasicInfo.objects.all() resource_name = 'client_basic_info' validation = FormValidation(form_class=ClientBasicInfoForm) list_allowed_methods = ['get', 'post', ] detail_allowed_methods = ['get', 'post', 'put', 'delete'] Edit: My resources file is now: from residence.models import ClientBasicInfo from residence.forms.profiler import ClientBasicInfoForm from tastypie import fields from tastypie.resources import ModelResource from tastypie.authentication import BasicAuthentication from tastypie.authorization import DjangoAuthorization, Authorization from tastypie.validation import FormValidation from tastypie.resources import ModelResource, ALL, ALL_WITH_RELATIONS from django.core.urlresolvers import reverse from django.contrib.auth.models import User class UserResource(ModelResource): class Meta: queryset = User.objects.all() resource_name = 'user' fields = ['username'] filtering = { 'username': ALL, } include_resource_uri = False authentication = BasicAuthentication() authorization = DjangoAuthorization() #def apply_authorization_limits(self, request, object_list): # return object_list.filter(username=request.user) def dehydrate(self, bundle): forms_incomplete = [] if ClientBasicInfo.objects.filter(user=bundle.request.user).count() < 1: forms_incomplete.append({'name': 'Basic Information', 'url': reverse('client_basic_info')}) bundle.data['forms_incomplete'] = forms_incomplete return bundle class ClientBasicInfoResource(ModelResource): # user = fields.ForeignKey(UserResource, 'user') class Meta: authentication = BasicAuthentication() authorization = DjangoAuthorization() include_resource_uri = False queryset = ClientBasicInfo.objects.all() resource_name = 'client_basic_info' validation = FormValidation(form_class=ClientBasicInfoForm) #list_allowed_methods = ['get', 'post', ] #detail_allowed_methods = ['get', 'post', 'put', 'delete'] def apply_authorization_limits(self, request, object_list): return object_list.filter(user=request.user) I made the user field of the ClientBasicInfo nullable and the POST seems to work. I want to try updating the entry now. Would that just be appending the pk to the ajax url? For example /api/private/client_basic_info/21/? When I submit that form I get a 501 NOT IMPLEMENTED message. What exactly haven't I implemented? I am subclassing ModelResource, which should have all the ORM-related functions implemented according to the docs.

  • How do common web frameworks (Django, Rails, Symfony, etc) handle multiple instances of the same plu

    - by Steven Wei
    Do any of the popular web frameworks solve this problem well? Here's an example: suppose you're running one of these web frameworks and you want to install a blog plugin. Except instead of a single blog, you need to run two separate instances of the blog plugin, and you want to keep them segregated. Or say you want to install multiple instances of a user authentication plugin, because you want to segregate your administrative users from your customer user accounts. Or say you want to install multiple instances of a wiki plugin for different parts of your site, or multiple instances of a comments plugin, or whatever else. It seems to me that at the basic level, each instance of plugin would need to be able to configured with a different set of database tables, and would need to be 'installed' at a different URL path. My experience is mostly with Django and Symfony, and I haven't seen a clean solution to this problem in either of them. They both tend to assume that each plugin (or app, in Django's case) is only ever going to be installed once. I'm curious if the Rails folks have figured out a clean solution to this problem, or any other framework authors (in any language). And if you were going to design a solution to this problem, what would it look like?

  • is there a signal emiter/consumer engine (like in Django) for .NET (C#)

    - by user118657
    Has .NET (C#) anything like Django's Signals engine? Our business logic become really complicated over few years of adding new features. I'm going to re-architecture it. Currently all features are very coupled that makes regression errors while changing something one one place - some other place may be broken. I really like Django's apps idea where separate applications introduce new functionality and are absolutely separate. Communication between apps is implemented though signals. I wounder if there is something in .NET that allows to divide project business to many separated "apps" (plug-ins, zones, modules, you name it) and make communication using some kind of "signals". For example we have simple order flow. We can add "coupon app" that if exists in the project adds abilities to use discount coupon. We can add "cross sale" module that if exists adds abilities to offer cross-sale products Email notification module that if exists adds abilities to send order email notifications. But in the same time all this modules are "self-contained" means that communication between them is done using emitting signals (ORDER_PROCCESS_START, ORDER_SUCCESS, etcs) and other modules can subscribe to this signals and process them in required way. This architecture is not related to web, all business logic is processed on the server side like without working with HTTP directly. I wonder if it's good architecture from code maintaining and testing point of few, is it possible to do this in .NET? Any drawbacks that I don't realize now?

  • jQuery - Show id, based on selected items class?

    - by Jon Hadley
    I have a layout roughly as follows: <div id="foo"> <!-- a bunch of content --> </div> <div id="thumbnails"> <div class="thumb-content1"></div> <div class="thumb-content2"></div> <div class="thumb-content3"></div> </div> <div id="content-1"> <!-- some text and pictures, including large-pic1 --> </div> <div id="content-2"> <!-- some text and pictures, including large-pic2 --> </div> <div id="content-3"> <!-- some text and pictures, including large-pic3 --> </div> etc .... On page load I want to show 'foo' and 'thumbnails' and hide the three content divs. As the user clicks each thumbnail, I want to hide foo, and replace it with the matching 'content-x'. I can get my head round jQuery show, hide and replace (although, bonus points if you want to include that in your example!). But how would I extract and construct the appropriate content id, from the thumbnail class, then pass it to the show hide code?
