  • How to get an array of all controllers in a Codeigniter project ?

    - by ashmckenzie
    I'd like to obtain a list of all controllers in a Codeiginiter project so I can easily loop through each of them and add defined routes. I can't seem to find a method that will give me what I'm after ? Here is the code snippet from the routes.php file where I would like to access the array: - // I'd like $controllers to be dynamically populated by a method // $controllers = array('pages', 'users'); // Loop through each controller and add controller/action routes // foreach ($controllers as $controller) { $route[$controller] = $controller . '/index'; $route[$controller . '/(.+)'] = $controller . '/$1'; } // Any URL that doesn't have a / in it should be tried as an action against // the pages controller // $route['([^\/]+)$'] = 'pages/$1';

  • How to secure an API written in .Net

    - by The Diamond Z
    This is a variation on an existing question in SO about securing/obfuscating .Net applications in general. I'm developing an API in C# that includes some algorithms I'm keen to protect. I understand no method will be perfect, but what's the generally accepted method for doing this? I'd like my clients to be able to code against the API but I don't want them to reverse engineer what's inside (at least I don't want to make it easy for them). If I obfuscate the code, won't that also obfuscate the API? We're looking at smartAssembly any thoughts comments on the product would be appreciated.

  • Constructors + Dependency Injection

    - by Sunny
    If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

  • How to structure a bigger/complicated project?

    - by Per
    Hello, I'm creating this (big?) project in high school where I'm programming the game Shithead (card game) (so that two people can play against eachother). I'll use mostly PHP, MySQL, JavaScript and Ajax. But I have never made a project like this before. I have only made like CMS-systems and so on. Do you guys have any tips on how I should structure this project? I'm also not so used to Object-oriented programming, but I guess I should consider this. Should I, for example, make a class for the cards? I'm very thankful for any tips or good links!

  • Fastest way to check for value existance.

    - by Itay Moav
    I have a list of values I have to check my input against it for existence. What is the faster way? This is really out of curiosity on how the internals work, not any stuff about premature optimization etc... 1. $x=array('v'=>'','c'=>'','w'=>); .. .. array_key_exists($input,$x); 2. $x=array('v','c','w'); .. .. in_array($input,$x);

  • How to make a service not receive messages at certain times

    - by miker169
    I'm currently learning wcf for an up and coming project. The service I am creating is using MSMQ to update the database, but the database can't accept messages at certain times. The service is going to be a windows service. The one thing I am coming up against at the moment is how I can get the service to stop reading messages from the queue at these times, for instance lets say I don't want to read messages from the queue on sundays. How would I go about implementing this. So that the client can send messages to the queue that update the database but the service doesn't read the messages until monday, so that the database gets all the updates on the monday? I have started looking at creating a customhost, but I'm not sure if I'm heading in the right direction with this. Thanks in advance.

  • Match Phrases (in array) in text string

    - by Tim Hanssen
    I'm using the Twitter API streaming to collect thousand of tweets every minute. They need to be matched to a list of keywords (can contain spaces). This is my current method: $text = preg_replace( '/[^a-z0-9]+/i', ' ', strtolower( $data['text'] ) ); $breakout = explode( " ", $text ); $result = array_intersect( $this->_currentTracks, $breakout ); I chop the tweet into words, and the matches them against my current keywords. This works well for all the keywords without a space ofc. If I wanted to find for example "Den Haag", It won't show up, because the string is exploded into words (based on the spaces). Any ideas about how I can do this in a quick way? Kind regards, Tim

  • Actionscript 2.0 element.text always outputs "00"

    - by Mbarry
    Hi everybody, I'm fighting against a strange behaviour with my actionscript! After setting the four integer variables from the MovieTimer sprite (hour, minute, second, mili-sec) and concate them i got always double zero: 00 stop (); delete this.onEnterFrame; var str1; var str2; var mili; var second; var minute; var hour; var timer; mili = _root.MovieTimer.txt_mili.text; second = _root.MovieTimer.txt_sec.text; minute = _root.MovieTimer.txt_min.text; hour = _root.MovieTimer.txt_heures.text; timer = hour+' : '+minute+' : '+second+' : '+mili; _root.MovieSpellFinish.TextTime.text = timer; _root.MovieSpellFinish.TextTime.text outputs: 00 is there any solutions for this??

  • finding last loop through a jQuery object

    - by DA
    Sample jquery. Assume $cog is a cached selector of multiple items. $cog.fadeOut('slow',function(){ alert('hey'); }) In that example, of $cog is a jQuery object of 4 DOM elements, the above will fade each element out one by one, and trigger an alert each time on the callback (4 alerts). I'd like to only call the alert when all 4 elements are done with their fadeOut function. This: $cog.fadeOut('slow',function(){ }) alert('hey'); when run, will show an alert, then the $cog elements disappear (I'm guessing due to timing issues with the fadeOut animation) Is there a way when calling a function against multiple DOM objects in a jQuery object to know when it's done with the last item?

  • Reverse Search Best Practices?

    - by edub
    I'm making an app that has a need for reverse searches. By this, I mean that users of the app will enter search parameters and save them; then, when any new objects get entered onto the system, if they match the existing search parameters that a user has saved, a notification will be sent, etc. I am having a hard time finding solutions for this type of problem. I am using Django and thinking of building the searches and pickling them using Q objects as outlined here: http://www.djangozen.com/blog/the-power-of-q The way I see it, when a new object is entered into the database, I will have to load every single saved query from the db and somehow run it against this one new object to see if it would match that search query... This doesn't seem ideal - has anyone tackled such a problem before?

  • EF Linq Product Sum when no records returned

    - by user1622713
    I’ve seen variations of this question all over the place but none of the answers work for me. Most of them are just trying to sum a single column too – nothing more complex such as the sum of a product as below: public double Total { get { return _Context.Sales.Where(t => t.Quantity > 0) .DefaultIfEmpty() .Sum(t => t.Quantity * t.Price); } } If no rows are returned I want to return zero. However if no rows are returned the .Sum() fails. There are various options of trying to insert Convert.ToDouble and using null coalesce operators, but they all still gave me errors. I’m sure I am missing a simple way to do this – any help greatly appreciated after too long banging head against google brick wall!

  • One on One table relation - is it harmful to keep relation in both tables?

    - by EBAGHAKI
    I have 2 tables that their rows have one on one relation.. For you to understand the situation, suppose there is one table with user informations and there is another table that contains a very specific informations and each user can only link to one these specific kind of informations ( suppose second table as characters ) And that character can only assign to the user who grabs it, Is it against the rules of designing clean databases to hold the relation key in both tables? User Table: user_id, name, age, character_id Character Table: character_id, shape, user_id I have to do it for performance, how do you think about it?

  • Why is the GUID structure declared the way it is?

    - by alabamasucks
    In rpc.h, the GUID structure is declared as follows: typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data[8]; } GUID; I understand Data1, Data2, and Data3. They define the first, second, and third sets of hex digits when writing out a GUID (XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX). What I never understood was why the last 2 groups were declared together in the same byte array. Wouldn't this have made more sense (and been easier to code against)? typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; WORD Data4; BYTE Data5[6]; } GUID; Anyone know why it is declared this way?

  • Using php to create a password system with chinese characters

    - by WillDonohoe
    Hi guys, I'm having an issue with validating chinese characters against other chinese characters, for example I'm creating a simple password script which gets data from a database, and gets the user input through get. The issue I'm having is for some reason, even though the characters look exactly the same when you echo them out, my if statement still thinks they are different. I have tried using the htmlentities() function to encode the characters, the password from the database encodes nicely, giving me a working '& #35441;' (I've put a space in it to stop it from converting to a chinese character!). The other user input value gives me a load of funny characters. The only thing which I believe must be breaking it, is it encodes in a different way and therefore the php thinks it's 2 completely different strings. Does anybody have any ideas? Thanks in advance, Will

  • Should I convert overly-long UTF-8 strings to their shortest normal form?

    - by Grant McLean
    I've just been reworking my Encoding::FixLatin Perl module to handle overly-long UTF-8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long UTF-8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?

  • Any way to make GetTypes() less brittle.

    - by scope-creep
    I'm iterating through all the types in GAC, GAC_32 and GAC_MSIL looking for specific types, fundamentally to match those using clauses in my source code, so when I compile the source. I'll know exactly what assembly dll's to provide. I'm getting all the file names from each of those directory and applying GetTypes to each assembly in turn and comparing the returned types against my using list. But the problem I have is that GetTypes() keeps crapping out with an exception, when it can't load the types from a loaded assembly. Is their any way to make GetTypes() less brittle. For instance, when parsing this assembly on my box, {blbmmc, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35}, it craps out. Any suggestions welcome. I know this is a fairly lengthly process, but I figure i'll eventually use a subset of common assemblies to search, or possibly cache the list of types-assembly dll name at program start. Thanks.

  • (newbie) type signature "Maybe a" doesn't like "Just [Event]"

    - by sisif
    i'm still learning Haskell and need help with the type inference please! using packages SDL and Yampa i get the following type signature from FRP.Yampa.reactimate: (Bool -> IO (DTime, Maybe a)) and i want to use it for: myInput :: Bool -> IO (DTime, Maybe [SDL.Event]) myInput isBlocking = do event <- SDL.pollEvent return (1, Just [event]) ... reactimate myInit myInput myOutput mySF but it says Couldn't match expected type `()' against inferred type `[SDL.Event]' Expected type: IO (DTime, Maybe ()) Inferred type: IO (DTime, Maybe [SDL.Event]) In the second argument of `reactimate', namely `input' In the expression: reactimate initialize input output process i thought "Maybe a" allows me to use anything, even a SDL.Event list? why is it expecting "Maybe ()" when the type signature is actually "Maybe a"? why does it want an empty tuple, or a function taking no arguments, or what is () supposed to be?

  • Design ideas for

    - by ZeroVector
    I need to design and I'm looking in to using WCF to accomplish this. Basically here is how I have it: Server process: Generate list of files to transfer across multiple FTP/SFTP sites in to a queue. Client(s): Talk to server to get files to transfer. Transfer the files acquired. All the data necessary to transfer the files will be present. Once transferred successfully, notify the server to remove it from the queue. Also, make sure no other client is trying to perform the transfer. Are there are any good articles/design patterns to use? I think it sounds like a good candidate for WCF since ideally it would be load balanced against a few machines. Development will be in C#/.NET 3.5.

  • How to select random image of specific size using Django / Python?

    - by Jonathan
    I've been using this little snippet to select random images. However I would like to change it to select only images of a certain size. I'm running into trouble checking against image size. If I use get_image_dimensions() I need to use a conditional statement, which then requires that I allow exceptions. So, I guess I need some pointers on just limiting by image dimensions. Thanks. import os import random import posixpath from django import template from django.conf import settings register = template.Library() def is_image_file(filename): """Does `filename` appear to be an image file?""" img_types = [".jpg", ".jpeg", ".png", ".gif"] ext = os.path.splitext(filename)[1] return ext in img_types @register.simple_tag def random_image(path): """ Select a random image file from the provided directory and return its href. `path` should be relative to MEDIA_ROOT. Usage: <img src='{% random_image "images/whatever/" %}'> """ fullpath = os.path.join(settings.MEDIA_ROOT, path) filenames = [f for f in os.listdir(fullpath) if is_image_file(f)] pick = random.choice(filenames) return posixpath.join(settings.MEDIA_URL, path, pick)

  • Rails 2.3.5: How to handle this type of validation

    - by randombits
    The use case is simple. I allow users to enter in an expiration field which needs to be between 1 and 15 into a form. The model takes that number and converts it into a datetime (such as adding 15 days from today) and stores it in the database. What's the correct way to actually validate that though? Do I validate against the datetime format that gets persisted in the database or the select box (1..15) that the user gets to pick through the form? I want to be able to validate that the user is putting in 1..15.. How is this done with ActiveRecord validation in Rails 2.3.5?

  • Safe way of iterating over an array or dictionary and deleting entries?

    - by mystify
    I've heard that it is a bad idea to do something like this. But I am sure there is some rule of thumb which can help to get that right. When I iterate over an NSMutableDictionary or NSMutableArray often I need to get rid of entries. Typical case: You iterate over it, and compare the entry against something. Sometimes the result is "don't need anymore" and you have to remove it. But doing so affects the index of all the rows, doesn't it? So how could I safely iterate over it without accidently exceeding bounds or jumping over an element that hasn't been checked?

  • database search function on an HTML page possible?

    - by synergy989
    Not sure if this is against stackoverflow rules as it's not a specific code question but I really need a little help. I want to know if it is possible to create a search feature (search box) on an HTML webpage that will query a database and return the results? Basically I have a database of products and their related categories. A user would come to the website, enter the category in the search field...somehow query the database and return the results on a new page. Note: the results page doesn't have to be HTML (could be PHP etc). If you could also include a little guidance on how (please nothing detailed, just need a direction). Thank you!

  • Unwanted Retriggering of Textbox Events

    - by user348917
    This is one of those "seems obvious" as how to do, but came across interesting side effect in implementing. I'm trying to keep two text boxes syncronized when information is updated. In this example, I will be using txtStartDate and txtEndDate. If the txtStartDate is changed, then the txtEndDate should should be updated. Likewise, if the txtEndDate changes, I want the txtSartDate to be updated. The side effect I'm comming across is that when I set them up under the TextChanged event for both, the events seem to retrigger against each other indefinately (endless loop?). Am I using the wrong event? Is this a task for a delegate?

  • Python: UTF-8 problems (again...)

    - by blahblah
    I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.
