  • NSMutable String "Out of scope"

    - by Garry
    I have two NSMutableString objects defined in my viewController's (a subclass of UITableViewController) .h file: NSMutableString *firstName; NSMutableString *lastName; They are properties: @property (nonatomic, retain) NSMutableString *firstName; @property (nonatomic, retain) NSMutableString *lastName; I synthesis them in the .m file. In my viewDidLoad method - I set them to be blank strings: firstName = [NSMutableString stringWithString:@""]; lastName = [NSMutableString stringWithString:@""]; firstName and lastName can be altered by the user. In my cellForRowAtIndexPath method, I'm trying to display the contents of these strings: cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ %@", firstName, lastName]; but this is causing the app to crash as soon as the view controller is displayed. Using the debugger, it seems that both firstName and lastName are "out of scope" or that they don't exist. I'm new to Xcode but the debugger seems to halt at objc_msgSend. What am I doing wrong?

  • Import Namespace System.Query

    - by GateKiller
    I am trying to load Linq on my .Net 3.5 enabled web server by adding the following to my .aspx page: <%@ Import Namespace="System.Query" %> However, this fails and tells me it cannot find the namespace. The type or namespace name 'Query' does not exist in the namespace 'System' I have also tried with no luck: System.Data.Linq System.Linq System.Xml.Linq I believe that .Net 3.5 is working because var hello = "Hello World" seems to work. Can anyone help please? Cheers, Stephen PS: I just want to clarify that I don't use Visual Studio, I simple have a Text Editor and write my code directly into .aspx files.

  • Is possible to auto-import a module from a diferent subfolder in other subfolder?

    - by mamcx
    I have a kind of plugin system, with this layout: - Python -- SDK -- Plugins ---- Plugin1 ---- Plugin2 All 3 have a __init__.py file. I wonder if is possible to be able to do import SDK from any plugin (as if SDK was in the site-packages folder). I'm in a situation where need to deploy, update, delete, add or change SDK files or any of the plugins under non-admin accounts, and wonder if I can get SDK in a clean way (I could sys.path.append in all plugins but I wonder if exist a better option). I imagine that using this in the Plugins init coulkd work: import sys import os ROOT_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__),'..')) print ROOT_DIR sys.path.append( ROOT_DIR ) But clearly is not executed this code (I imagine init was auto-magicalled executed in the load of the module :( )

  • Routing a location that matches one controller to another

    - by Luca Romagnoli
    Hi I have a controller named "places" with some actions like "view", "new", "create" When a user goes to mysite.com/places I want to execute the action "show" of another controller called "cores" So I've put this in the routes.rb file: map.connect '/:id/show', :controller => "cores", :action => "show" But it doesn't work.

  • NSInvocationOperation and main thread

    - by kpower
    Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

  • When is a C++ terminate handler the Right Thing(TM)?

    - by Joseph Garvin
    The C++ standard provides the std::set_terminate function which lets you specify what function std::terminate should actually call. std::terminate should only get called in dire circumstances, and sure enough the situations the standard describes for when it's called are dire (e.g. an uncaught exception). When std::terminate does get called the situation seems analagous to being out of memory -- there's not really much you can sensically do. I've read that it can be used to make sure resources are freed -- but for the majority of resources this should be handled automatically by the OS when the process exits (e.g. file handles). Theoretically I can see a case for if say, you needed to send a server a specific message when exiting due to a crash. But the majority of the time the OS handling should be sufficient. When is using a terminate handler the Right Thing(TM)? Update: People interested in what can be done with custom terminate handlers might find this non-portable trick useful.

  • Facebook connect integration (registration & login)

    - by nikospkrk
    Hi, I'm really struggling to make facebook connection working for my system. What I want to do : When the user is not yet registered on facebook : Fetch some user profile fields into my database (ideqally via my registration page already working for non facebook users) Log the user into my website Redirect the user into my homepage What I've done so far : Set up the application in FB Add the Facebook class from the github website and integrate some code to make it working Add additionnal paremeters to login/register facebook link. I'm struggling to redirect the user after authorizing, to my register page (register/?facebook). The "Post-Authorize Redirect URL" field doesn't seem to work properly, I maybe do not fill the right field? My other question is, if my registration page uses a redirection show (index.php redirect to register.php), do the information given by facebook through the $_POST method would be available in the register.php page ? I don't think so, do you ? Regards, Nicolas.

  • Splitting string on probable English word boundaries

    - by Sean
    I recently used Adobe Acrobat Pro's OCR feature to process a Japanese kanji dictionary. The overall quality of the output is generally quite a bit better than I'd hoped, but word boundaries in the English portions of the text have often been lost. For example, here's one line from my file: softening;weakening(ofthemarket)8 CHANGE [transform] oneselfINTO,takethe form of; disguise oneself I could go around and insert the missing word boundaries everywhere, but this would be adding to what is already a substantial task. I'm hoping that there might exist software which can analyze text like this, where some of the words run together, and split the text on probable word boundaries. Is there such a package? I'm using Emacs, so it'd be extra-sweet if the package in question were already an Emacs package or could be readily integrated into Emacs, so that I could simply put my cursor on a line like the above and repeatedly invoke some command that splits the line on word boundaries in decreasing order of probable correctness.

  • Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

    - by mark smith
    Hi there, I just updated an app from .net 2.0 to .net 4.0 and i have noticed the following... For example i have the following control.. <input type="hidden" name="ctl00$cphMain$hfdFueraHorarioOficinaConfirmado" id="cphMain_hfdFueraHorarioOficinaConfirmado" value="False" /> and then in javascript i did this before.. var hfdFueraHorarioOficinaConfirmado=document.getElementById('ctl00_cphMain_hfdFueraHorarioOficinaConfirmado'); but after checking the Id within the html source once it renders and also doing some debugging with firebug etc.... it has changed from ctl00_cphMain_hfdFueraHorarioOficinaConfirmado to cphMain_hfdFueraHorarioOficinaConfirmado can anyone explain why? .... so should i basically do a search and replace and remove the ctl00?????? A little confused Obviosuly the javascript line with the the ctl00_ infront return NULL because it doesn't exist, but removing this returns the object.. Any help or ideas really appreciated Thanks

  • Naming a typedef for a boost::shared_ptr<const Foo>

    - by Blair Zajac
    Silly question, but say you have class Foo: class Foo { public: typedef boost::shared_ptr<Foo> RcPtr; void non_const_method() {} void const_method() const {} }; Having a const Foo::RcPtr doesn't prevent non-const methods from being invoked on the class, the following will compile: #include <boost/shared_ptr.hpp> int main() { const Foo::RcPtr const_foo_ptr(new Foo); const_foo_ptr->non_const_method(); const_foo_ptr->const_method(); return 0; } But naming a typedef ConstRcPtr implies, to me, that the typedef would be typedef const boost::shared_ptr<Foo> ConstRcPtr; which is not what I'm interested in. An odder name, but maybe more accurate, is RcPtrConst: typedef boost::shared_ptr<const Foo> RcPtrConst; However, Googling for RcPtrConst gets zero hits, so people don't use this as a typedef name :) Does anyone have any other suggestions?

  • Windows API GUI programming

    - by genesys
    Hi! I'm working on a Project with outdated, very old looking GUI (the used GUI framework is more than 10 years old) Since the used programming language is Eiffel, there are almost no good libraries for GUI development. Although Wrappers for C libraries exist, it's not that easy to wrap something like Qt with them. The current GUI framework uses the Windows API to create windows, widgets and so on. But as stated - it's very old. Now i would like to learn more about how to use the Windows API directly to create state of the art GUI's Can someone recommend any reading material? Thanks!

  • Authenticating a Server with Digital Signatures

    - by TomS
    I understand how Non-repudiation and Integrity are achieved with Digital Signatures, but it's the Authentication that I don't grasp yet. I'm developing a Client-Server application in C#, that should be capable of Authentication with Digital Certificates and Digital Signatures. I know how to check the validity and integrity of a Signature (with SignedCms.CheckSignature()), but how does this authenticates any of the parts involved? For example: The client asks the Server for a Digital Signature, The client receives the signature and validates it, If the validation succeeds, continue. The client could be a victim of a man-in-the middle attack and receive a valid signature in step 2. The validation would succeed, but the client wouldn't be talking to the right server. What am I missing?

  • Regex find and copy in bash (preserving folder structure)?

    - by Jonathan Sternberg
    I have a folder with a bunch of log files. Each set of log files is in a folder detailing the time and date that the program was run. Inside these log folders, I've got some video files that I want to extract. All I want is the video files, nothing else. I tried using this command to only copy the video files, but it didn't work because a directory didn't exist. .rmv is the file extension of the files I want. $ find . -regex ".*.rmv" -type f -exec cp '{}' /copy/to/here/'{}' If I have a folder structure such as: |- root | |--- folder1 | |----- file.rmv | |--- folder2 | |----- file2.rmv How can I get it to copy to copy/to/here with it copying the structure of folder1 and folder2 in the destination directory?

  • Testing complex entities

    - by Carlos
    I've got a C# form, with various controls on it. The form controls an ongoing process, and there are many, many aspects that need to be right for the program to run correctly. Each part can be unit tested (for instance, loading some coefficients, drawing some diagnostics) but I often run into problems that are best described with an example: "If I click here, then here, then change this, then re-open the form, then click here, it crashes or produces an error" I've tried my best to use common code organisational ideas (inheritance, DRY, separation of concerns) but there never seems to be a way to test every single path, and inevitably, a form with several controls will have a huge number of ways to execute. What can I read (preferably online) that addresses this kind of issue, and is there a (non-generic) term for it. This isn't a specific problem I'm having, but one that creeps up on me, especially with WinForms.

  • Rewrite Query String

    - by Virgil
    Hello, I am trying to write some mod_rewrite rules to generate thumbnails on the fly. So when this url example.com/media/myphoto.jpg?width=100&height=100 the script should rewrite it to example.com/media/myphoto-100x100.jpg and if the file exists on the disk it gets served by Apache and if it doesn't exist it is called a script to generate the file. I wrote this RewriteCond %{QUERY_STRING} ^width=(\d+)&height=(\d+) RewriteRule ^media/([a-zA-Z0-9_\-]+)\.([a-zA-Z0-9]+)$ media/$1-%1x%2.$2 [L] RewriteCond %{QUERY_STRING} ^(.+)? RewriteRule ^media/([a-zA-Z0-9_\-\._]+)$ media/index.php?file=$1&%1 [L] and I get infinite internal redirects. The first condition is matched and the rule is executed and right after that I get an internal redirect. I need advice to finish this script. Thank you.

  • How can I create two contructors that act differently but recieve the same data type?

    - by Sergio Tapia
    public class Parser { Downloader download = new Downloader(); HtmlDocument Page; public Parser(string MovieTitle) { Page = download.FindMovie(MovieTitle); } public Parser(string ActorName) { Page = download.FindActor(ActorName); } } I want to create a constructor that will allow other developers who use this library to easily create a Parser object with the relevant HtmlDocument already loaded as soon as it's done creating it. The problem lies in that a constructor cannot exist twice with the same type of parameters. Sure I can tell the logical difference between the two paramters, but the computer can't. Any suggestions on how to handle this? Thank you!

  • Developing Silverlight 1.0 Applications on VS2008 SP1

    - by Moo
    Hi, Can anyone point me to any guides, howto's or general documentation on how to develop Silverlight 1.0 (it has to be 1.0) on VS2008 SP1. I have searched high and low for information, and it all seems to be out of date (referencing Silverlight 1.0 Tools for Visual Studio 2008 beta, release candidate and alpha packages) or just plain doesn't work under VS2008 SP1. What do I need to install, and which project do I need to create? I have installed the Silverlight 1.0 SDK, which gave me no starting point, the Silverlight 2.0 Tools for Visual Studio after a website suggested you could use that to develop 1.0 apps, but the suggested template doesn't exist, and Silverlight 3.0 Tools for Visual Studio, which was a last ditch resort.

  • Quick MySQLi security question

    - by Benjamin Falk
    I have a quick MySQLi security related question... For example, take a look at this code (gets in put from the user, checks it against the database to see if the username/password combination exist): $input['user'] = htmlentities($_POST['username'], ENT_QUOTES); $input['pass'] = htmlentities($_POST['password'], ENT_QUOTES); // query db if ($stmt = $mysqli->prepare("SELECT * FROM members WHERE username=? AND password = ?")) { $stmt->bind_param("ss", $input['user'], md5($input['pass'] . $config['salt'])); $stmt->execute(); $stmt->store_result(); // check if there is a match in the database for the user/password combination if ($stmt->num_rows > 0) {} } In this case, I am using htmlentities() on the form data, and using a MySQLi prepared statement. Do I still need to be using mysql_real_escape_string()?
