• Tableview with sections managed by fetched results controller

  - by Matthes

  Hi, I'm quite new to CoreData and need help with one issue. I have tableview which simply lists cities stored in SQLite db. City is defined by "cityId" and "name" attributes. Data are fetched using NSFetchedResultsController and everything works fine except that I can't figure out how to make FetchedResultsController to group cities by first letter of city names. When I supply "name" for sectionNameKeyPath argument of initWithFetchRequest:managedObjectContext:sectionNameKeyPath:cacheName: method, it creates section for each city, which is obviously something I don't want. I can't figure out how to create an expression which would make it work in way I need. thanks for any tips and/or advices on this Matthes

• Attaching files to WCF REST service responses

  - by David Seiler

  I have a resource that looks something like this: /users/{id}/summary?format={format} When format is "xml" or "json" I respond with a user summary object that gets automagically encoded by WCF - fine so far. But when format equals "pdf", I want my response to consist of a trivial HTTP response body and a PDF file attachment. How is this done? Hacking on WebOperationContext.Current.OutgoingResponse doesn't seem to work, and wouldn't be the right thing even if it did. Including the bits of the file in a CDATA section or something in the response isn't safe. Should I create a subclass of Message, then provide a custom IDispatchMessageFormatter that responds with it? I went a short distance down that path but ultimately found the documentation opaque. What's the right thing?

• Setting up path mapping in PHP and Eclipse

  - by jax

  I have just setup my website locally so I can test my pages more easily. Eclipse has been configured to use an XAMPP server locally. The problem is that I want to map my project to a certain place in my website. ie. In my Eclipse PHP project I have a folder called com I want this to map to /com in the webstie. I tried to do this in the mapping section of the Eclipse server setup but it didn't work. When I type http://localhost/com/ It should go to my project folder, however, when I type other folder it should use the normal website folders. how can I do this?

• GCC: visibility of symbols in standalone C++ applications

  - by Albert

  Hi, Because of a strange C++ warning about the visibility of some symbols and an interesting answer, linking to a paper which describes the different visibility types and cases (section 2.2.4 is about C++ classes), I started to wonder if it is needed for a standalone application to export symbols at all (except main - or is that needed?). Why exactly are they needed to be exported in standalone applications? Is "an exported symbol" an synomym for "visible symbol"? I.e. a hidden symbol is a symbol which is not exported? Do the object files already differ between visible symbols and hidden symbols? Or is this made at the linking step, so that only the visible symbols are exported? Does the visibility of symbols matter in case for debug information? Or is that completely independent, i.e. I would also get a nice backtrace if I have all symbols hidden? How is STABS/DWARF related to the visibility of symbols?

• Overlapping images w/ image maps obstructing each other

  - by Hamster

  Information: The images have large transparent sections, so each must be overlapped to create the needed effect. Specifically, the clickable portions of each image are in weird trapezoid shapes meant to be pressed up against each other. Images have image maps with large portions being overlapped by the transparent portions of other nearby (trapezoid) images. I don't expect any change in z indexes will solve this... Combining the image files into a larger single one to overlay a single image map for each section seems less than ideal, especially since I may need to re-order or rename them later and such. Never mind hover animations and other possibilities down the road. What would be the best workaround?

• Optimize included files and uses in Delphi

  - by Roland Bengtsson

  I try to increase performance of Delphi 2007 and Codeinsight. In the application there are 483 files added in the DPR file. I don't know if it is imagination but I feel that I got better performance from Codeinsight by simply readd all files in the DPR. I also think (correct me if I'm wrong) that all files that are included in a uses section also should be included in the DPR file for best performance. My question is, does it exists a tool that scan the whole project and give a list what files are missing in the DPR file and what files can be removed? Would also be nice to have a list of uses that can be removed in the PAS files. Regards

• Where exactly should I attach script in HTML

  - by bzxcv7

  I have read about several ways to embed Javascript in HTML document. First, in head section: <head> ... <script src="abc.js"></script> </head> Second, in the end of document's body: <body> <!-- content --> <script src="abc.js"></script> </body> First way is more esthetic, but second version assures that all the items in DOM are loaded. I use HTML5 (but probably it doesn't matters) Which way is better and why?

• How to unit test configs

  - by ForeverDebugging

  We're working with some very large config files which contain lots of Unity and WCF configuration. When we open some of these configs in the SVC config editor or even try to open a web application using these configs, we recieve errors showing any typos or errors. E.g. a WCF binding is invalid or does not exist etc, or a configuration section does not exist, two endding tags, etc. Is there some way to "valid" a config through a unit test? So there's one less thing which could go wrong when the application is moved into a new environment.

• How to configure a OCUnit test bundle for a framework?

  - by GuidoMB

  I've been developing a Mac OS X framework and I want to use OCUnit in my XCode 3.2.1 project. I've followed several tutorials on how to configure a OCUnit test bundle. The problem is that when I create a test case that uses a function that is defined in one of the framework's sources, I get a building error telling me that the symbol is not found. I made the test bundle dependent of my project's target as the tutorial said, but that doesn't seem to be problem. First I thought that I could solve this problem by dragging the framework's source files into the compile sources section within the Test bundle target, but then all the symbols referenced from that source file started to show up in the build errors, so that seems to not be a good solution/idea. How can I configure my unit test bundle so it builds properly?

• Html encoding in MVC input

  - by fearofawhackplanet

  I'm working through NerdDinner and I'm a bit confused about the following section... First they've added a form for creating a new dinner, with a bunch of textboxes delcared like: <%= Html.TextArea("Description") %> They then show two ways of binding form input to the model: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create() { Dinner dinner = new Dinner(); UpdateModel(dinner); ... } or: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Dinner dinner) { ... } Ok, great, that all looks really easy so far. Then a bit later on they say: It is important to always be paranoid about security when accepting any user input, and this is also true when binding objects to form input. You should be careful to always HTML encode any user-entered values to avoid HTML and JavaScript injection attacks Huh? MVC is managing the data binding for us. Where/how are you supposed to do the HTML encoding?

• workflow assign task to multiple users

  - by Artru

  I have MOSS. I want to make a page where a user, say administrator, could send some instructions to a server, for example using standard library and make task for a group of users forcing them to read files. After the reading users would press "already read it" and administrator would know who did it/who did not. I created simple workflow in office designer and choose assigne task to Group1, which is in the sharepoint server. After WF run everyone who is in Group1 get message about a task, that's great. However this task is general for group and if we go to the site section "current tasks", we can see it, while I want this task for every person in Group1. Futher question, is it possible to create form where administrator will choose users for this task, 'cause now I munualy set group in WF.

• "_FILE_AND_LINE_ is not defined in this scope" (compiling RakNet NAT examples in OS X)

  - by Michael F

  Hello! I'm working on a RakNet-based project (using 3.8 on OS X 10.6), and I'm trying to work through the various examples that demonstrate the parts of RakNet I want to use. For the "NatCompleteClient" example, I've imported the source into a command-line project in XCode, along with the UPNP dependency. At compile time I've had a few errors in the UPNP section, though, and I can't find any guidance on this. In UPNPPortForwarder.mm, there are 7 lines that use _FILE_AND_LINE_, and the compiler is not happy; for example on line 232: foundInterfaces.Deallocate(r1,_FILE_AND_LINE_); causes: UPNPPortForwarder.mm:232: error: '_FILE_AND_LINE_' was not declared in this scope Can anyone tell me what this is all about? That variable doesn't seem to get talked about very often... or Google doesn't like to find it.

• UITableView - Color a selectede cell in table (remain colored)

  - by Liron Loop

  Hi In my app i'm using a UITableViewController ("grouped style") which in one of its section I want the user to be able to see what he had selected by making this cell colored and other "uncolored". Doing it by updating all cells' background color and reloading table data, each time user touches a cell (in didSelectRowAtIndexPath:) Problem is that there is some processing made in the didSelectRowAtIndexPath: so the color doesn't get changed right a way, rather in a bit delay after touch was made. (I gusse the processing is the resone for the tiny delay) Is there a better way of doing it? Any help will be appreciated Liron P.S. I'm new to all of this...

• Installed Android on Mac, cannot find SDK

  - by David Matuszek

  Using Mac OS X 10.6.2, Eclipse SDK 3.5.2. I installed the Android plugin, following the instructions at: http://developer.android.com/sdk/eclipse-adt.html In the next section (step #3) it says: For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory. I cannot find such a directory. When I try some other directory, it says the directory has no 'tools' folder, so I've searched for a 'tools' folder, but none of those found (of 15 or 20) appear to be Android. Where is this directory??? --Dave [email protected]

• Is it a good idea to keep documentation in the VCS?

  - by Jj

  At work we just moved to Mercurial for our VCS from SVN. In SVN we used to have a "docs" folder next to "trunk", in "docs" we would keep all our file documentation, client files, diagrams, mockups, etc. (we use a wiki(Redmine) for internal documentation). Now in a DVCS enviroment we don't need a "trunk" folder, so we drop the code at the root of the repo, and now having a "docs" folder inside the repo feels weird being at the same level that the code. This has taken me to reconsider if it is a good idea to keep those files in the VCS, we have a "documents" section in Redmine, but I have never used it because it is a pain to have to download a file each time I want to open it and I can't access the file when I'm offline. What best practices have you guys found to manage these kind of non-code files?

• Backbone: rendering syntax

  - by ksol

  We're using Backbone.js in one of my team's projects, and this is the first time I use it. I've seen many times this kind of code (it's coffeescript, but clear enough I think. @ means this.) clients_view = new Homespa.Views.Orders.Clients.SectionView(collection: @options.clients) @$("#clients-section").html(clients_view.render().el) clients_search_view = new Homespa.Views.Orders.Clients.SearchView @$("#clients_search_modal").html(clients_search_view.render().el) Isn't there a better way to do this? I would expect to just call render on my view, and then everything's good, I shouldn't have to get the html and append/replace it by hand. Thanks for you time !

• Trouble Getting a Locally Hosted Copy of the English Language Wiktionary to include the Translations Sections

  - by user1436026

  I used MWDumper - http://www.mediawiki.org/wiki/Mwdumper - to import the xml dump of the English Language Wiktionary (specifically the file named enwiktionary-20120930-pages-meta-current.xml,) to my local server. I have found that under the Translations section (on each page for each English word,) next to the name of each language where I should be able to see the definition in a foreign language, I instead see Template:Tø, Template:T+, or Template:T- and I am not sure why this is. As an experiment, I also used WikiTaxi - http://www.yunqa.de/delphi/doku.php/products/wikitaxi/index - with the exact same XML dump and did not have this problem when viewing under WikiTaxi.exe. I have been searching through mediawiki.org looking for the answer, but have so far not been successful. I appreciate your help

• How to add second project to the repository?

  - by Banani

  Hi! I have setup subversion 1.6.5 on Fedora. I have decided to use a single repository for multiple projects. I have added one project, projA, to the repository. I will have more projects to add to the repository in future. If I try to add next project with the command 'svn import . file:///path/to/repos' gives svn: File already exists: filesystem '/usr/local/svn-repos/proj-test/db', transa ction '1-1', path '/trunk'. The new projB is being added to the trunk directory of projA. I have read the section "Adding Projects" in http://svnbook.red-bean.com/en/1.1/ch05s04.html In that book, projects are added at once. But,I would like to add them one by one as new projects become ready to go. What is the proper command and/or how that can be done? Thanks. Banani

  Hey Few Questions 1.Is it legal to have an IFrame on a website which inside has an external website? 2.In an IFrame is it possible to only show a section of the src that isnt the top left of the site (for instance if there was a chart in the middle of a website, could u have just the chart in your Iframe, or atleast start it centred there) 3.Any way to stop my IFrame from auto redirecting me to the external site for 3: ie <iframe src="http://fifa.com"></iframe> Just sends me to fifa instead of actually showing that site in a frame.
