  • Debug Mode for CodeIgniter?

    - by nebukadnezzar
    Does CodeIgniter provide a Debug Mode, for example, when accessing an Invalid URL? Ruby on Rails does show debugging Messages when a incorrect URL has been given, and the controller is unable to resolve it using the routes map. How would I enable such debugging messages in CodeIgniter? The profiler ... $this->output->enable_profiler(TRUE); ... only affects single classes, but not all routes. So debugging without an actual debugger mode is a little... difficult. :-)

  • DDK/WDM developing problem ... driver won't load on x64 windows platform

    - by user295975
    Hi there! I am a beginner at DDK/WDM driver developing field. I have a task which involves porting a virtual device driver from x86 to x64 (intel). I got the source code, I modified it a bit and compiled it succesfuly with DDK (build environments). But when I tried to load it on a ia64 Windows7 machine it didn't want to load. Then I tried some simple examples of device drivers from --http://www.codeproject.com/KB/system/driverdev.aspx (I put '--' to be able to post the hyperlink) and from other links but still the same problem. I hear on a forum that some libraries that you use to link are not compatible with the new machines and suggested to link to another similar libraries...but still didn't worked. When I build I use "-cefw" command line parameters as suggested. I do not have an *.inf file asociated but I'm copying it in system32/drivers and I'm using WinObj to see if next restart it's loaded into the memory. I also tried this program ( http://www.codeproject.com/KB/system/tdriver.aspx ) to load the driver into the memory but still didn't worked for me. Please please help me...I'm stuck on this and my deadline already passed. I feel I'driving nuts in here trying to discover what am I doing wrong.

  • Change Emacs Default Coding System

    - by Saterus
    My problem stems from Emacs inserting the coding system headers into source files containing non-ascii characters: # -*- coding: utf-8 -*- My coworkers do not like these headers being checked into our repositories. I don't want them inserted into my files because Emacs automatically detects that the file should be UTF-8 regardless so there doesn't seem to be any benefit to anyone. I would like to simply set Emacs to use UTF-8 automatically for all files, yet it seems to disagree with this idea. In an effort to fix this, I've added the following to my .emacs: (prefer-coding-system 'utf-8) (setq coding-system-for-read 'utf-8) (setq coding-system-for-write 'utf-8) This does not seem to solve my problem. Emacs still inserts the coding-system headers into my files. Anyone have any ideas? EDIT: I think this problem is specifically related to ruby-mode. I still can't turn it off though.

  • Behavior of retained property while holder is retained

    - by Aurélien Vallée
    Hello everyone, I am a beginner ObjectiveC programmer, coming from the C++ world. I find it very difficult to understand the memory management offered by NSObject :/ Say I have the following class: @interface User : NSObject { NSString* name; } @property (nonatomic,retain) NSString* name; - (id) initWithName: (NSString*) theName; - (void) release; @end @implementation User @synthesize name - (id) initWithName: (NSString*) theName { if ( self = [super init] ) { [self setName:theName]; } return self; } - (void) release { [name release]; [super release]; } @end No considering the following code, I can't understand the retain count results: NSString* name = [[NSString alloc] initWithCString:/*C string from sqlite3*/]; // (1) name retainCount = 1 User* user = [[User alloc] initWithName:name]; // (2) name retainCount = 2 [whateverMutableArray addObject:user]; // (3) name retainCount = 2 [user release]; // (4) name retainCount = 1 [name release]; // (5) name retainCount = 0 At (4), the retain count of name decreased from 2 to 1. But that's not correct, there is still the instance of user inside the array that points to name ! The retain count of a variable should only decrease when the retain count of a referring variable is 0, that is, when it is dealloced, not released.

  • How to use Obj-C classes in MacRuby

    - by beno1604
    I am trying to use an external Obj-C class in my MacRuby project, but I can't figure out how to import it. Specifically, I want to use ObjectiveResource inside a MacRuby 0.5 project (since ActiveResource doesn't work - yet). I have gotten as far as the 'framework' command in MacRuby, but it only seems to apply to actual frameworks. Questions: where should I install the objective-resource directory? how do I pull these classes inside my ruby code? Thanks for any help!

  • Programming challenge: can you code a hello world program as a Palindrome?

    - by Assaf Lavie
    So the puzzle is to write a hello world program in your language of choice, where the program's source file as a string has to be a palindrome. To be clear, the output has to be exactly "Hello, World". Edit: Well, with comments it seems trivial (not that I thought of it myself of course [sigh].. hat tip to cobbal). So new rule: no comments. Edit: I feel kind of bad editing someone else's question to say this, but it will eliminate a lot of non-palindromes that keep popping up, and I'm tired of seeing the same simple mistake over and over. The following is NOT a palindrome: ()() The following IS a palindrome: ())( Brackets, parenthesis, and anything else that must match are a major barrier to palindrome-ing, yes, but that doesn't mean you can ignore them and post non-palindrome answers. Languages represented thus far: C, C++, Bash, elisp, C#, Perl, sh, Windows shell, Java, Common Lisp, Awk, Ruby, Brainfuck, Funge, Python, Machine Language, HQ9+, Assembly, TCL, J, php, Haskell, io, TeX, APL, Javascript, mIRC Script, Basic, Orc, Fortran, Unlambda, Pseudo-code, Befunge, CFML, Lua, INTERCAL, VBScript, HTML, sed, PostScript, GolfScript, REBOL, SQL

  • What is a good motivating example for dataflow concurrency?

    - by Alex Miller
    I understand the basics of dataflow programming and have encountered it a bit in Clojure APIs, talks from Jonas Boner, GPars in Groovy, etc. I know it's prevalent in languages like Io (although I have not studied Io). What I am missing is a compelling reason to care about dataflow as a paradigm when building a concurrent program. Why would I use a dataflow model instead of a mutable state+threads+locks model (common in Java, C++, etc) or an actor model (common in Erlang or Scala) or something else? In particular, while I know of library support in the languages above (and Scala and Ruby), I don't know of a single program or library that is a poster child user of this model. Who is using it? Why do they find it better than the other models I mentioned?

  • Screen scrape a web page that uses javaScript and frames

    - by Mello
    Hi, I want to scrape data from www.marktplaats.nl . I want to analyze the scraped description, price, date and views in Excel/Access. I tried to scrape data with Ruby (nokogiri, scrapi) but nothing worked. (on other sites it worked well) The main problem is that for example selectorgadget and the add-on firebug (Firefox) don’t find any css I can use to scrape the page. On other sites I can extract the css with selectorgadget or firebug and use it with nokogiri or scrapi. Due to lack of experience it is difficult to identify the problem and therefore searching for a solution isn’t easy. Can you tell me where to start solving this problem and where I maybe can find more info about a similar scraping process? Thanks in advance!

  • jQuery: Using autocomplete to add values to two fields instead of one

    - by rayne
    I want to use the autocomplete plugin for jQuery to populate not one, but two fields when selecting one of the autocomplete values - the name of a band is entered in the #band input field, but the band url (if exists) should also automatically be added to the #url input field when selecting the band name. Right now I simply have an un-pretty list in an external php file from which the autocompleter takes it's values: $bands_sql = "SELECT bands.name, bands.url FROM bands ORDER BY name"; $bands_result = mysql_query($bands_sql) or print (mysql_error()); while ($bands_row = mysql_fetch_array($bands_result)) { $band_name = $bands_row['name']; $band_url = $bands_row['url']; echo $band_name."\n"; #needs to be replaced with an array that holds name and url } My autocomplete function looks very basic atm, but as I'm an absolute beginner when it comes to jQuery (and also clueless when it comes to PHP arrays), I have no idea how to tell it to populate two fields and not one. $(document).ready(function() { $("#band").autocomplete('/autocomplete-bands.php'); }); Is that even possible?!

  • Line Break in XML?

    - by ew89
    Hello, I'm a beginner in web development, and I'm trying to insert line breaks in my XML file. This is what my XML looks like: Song Title Lyrics <song> <title>Song Title</title> <lyric>Lyrics</lyric> <song> <title>Song Title</title> <lyric>Lyrics</lyric> <song> <title>Song Title</title> <lyric>Lyrics</lyric> I want to have line breaks in between the sentences for the lyrics. I tried everything from /n, and other codes similar to it, PHP parsing, etc., and nothing works! Have been googling online for hours and can't seem to find the answer. I'm using the XML to insert data to an HTML page using Javascript. Does anyone know how to solve this problem? Thanks before :)

  • How to use Netbeans platform syntax highlight with JEditorPane?

    - by Volta
    There are many tutorials online giving very complex or non-working examples on this. It seems that people recommend others to use the syntax highlighters offered by netbeans but I am totally puzzled on how to do so! I have checked many many sites on this and the best I can find is : http://www.antonioshome.net/kitchen/netbeans/nbms-standalone.php However I am still not able to use this example (as it is aimed to people who don't want to use the Netbeans platform but just a portion of it) and I am still not sure if I can just use syntax highlighting in a simple plug 'n play way. For example netbeans supports several language highlights by default, can I just use the highlighters in a JEditorPane to parse Ruby/Python/Java for example ? or do I need to write my own parser :-| ? I will really appreciate a small simple example on how to plug syntax highlight in a standalone application using the netbeans platform.

  • What (kind of) project could I create to learn JavaScript?

    - by Aziz Light
    Hello, I started learning JavaScript a while ago. It's a fairly easy programming language considering that I learned Java in university, that I know php pretty well and that I already played around with python and ruby. The problem is that to properly learn a programming language I usually create a project. In javascript, I just don't know what kind of project I could create - that is, a project that is not web-based or related to the web browser. Can I create javascript shell scripts? Where is javascript commonly used beside the web browsers? So, can someone actually give me some ideas please?

  • Programming related name for a kitten? [closed]

    - by andrhamm
    I am a programmer and I just got my first kitten. A Google search for nerdy/geeky cat names was unimpressive. She's a little black kitten with a very courageous and adventurous attitude! She has a little light gray spot on her chest which might turn white with time. Here she is on my Flickr Which name would you suggest? Which of these do you like? It should be something short that has a couple contrasting sounds so it stands out a bit when you say it. PHP is my favorite scripting language but it makes for a lousy name :P Java Pixel Perl Ruby Gizmo Mocha Thanks for the help!

  • Tool for parsing smtp logs that finds bounces

    - by Željko Filipin
    Our web application sends e-mails. We have lots of users, and we get lots of bounces. For example, user changes company and his company e-mail is no longer valid. To find bounces, I parse smtp log file with log parser. Some bounces are great, like 550+#[email protected]. There is [email protected] in bounce. But some do not have e-mail in error message, like 550+No+such+recipient. I have created simple ruby script that parses logs (uses log parser) to find which mail caused something like 550+No+such+recipient. I am just surprised that I could not find a tool that does it. I have found tools like zabbix and splunk for log analysis, but they look like overkill for such simple task. Anybody knows a tool that would parse smtp logs, find bounces and e-mails that cause them? Edit: smtp server is microsoft smtp server.

  • AS3 - Can't access properties or methods of a MC child that has been added in script

    - by Chris
    Hi All - I am still a bit of a beginner at AS3, so bear with me, please. I have created a loop to instantiate tiles on a board. In the following example, "Gametiles" is an array containing objects of class "Tile" which is a class that extends MovieClip. "Game" is a MC that I added to the stage in the flash developing environment. for(var i:uint=0;i < Gametiles.length;i++){ var pulledTile = Gametiles[i]; var tilename:String = "I_Tile_" + pulledTile.grid_y + "_" + pulledTile.grid_x; var createdTile = new InteractiveTile(); pulledTile.addAnims(createdTile); Game.addChildAt(pulledTile, 0); Game.getChildAt(0).name = tilename; } The above code works - but with a tricky problem. If I did something like the following: trace(Game.I_Tile_1_3.x); I get "TypeError: Error #1010: A term is undefined and has no properties." However, I am able to access theses children in the following manner: var testing = Game.getChildByName("I_Tile_1_3") trace(testing.x); This method is a bit cumbersome though. I really don't want to have to create a var and call getChildByName every time I want to interact with these properties or methods. How can I set up these children so that I can access them directly without the extra steps?

  • Umbraco template issues

    - by bomortensen
    Hi fellow Umbraco users, I'm currently building my first umbraco website and since I'm completely new to umbraco I've already ran into a problem which I'm sure is pretty straight-forward to do. That said, I'm by no means a beginner when it comes to building sites that run on a (open source) CMS as I've been using Joomla! since it was called Mambo. Anyway, the site I'm building is here: my site What I want to do is to have some content in the white box that changes when you mouseover/hover one of the menu items. Also that content has to stay "active" when you've clicked on a link (i.e. if you click on "Profile" I need to highlight the Profile menu item with the gray color and the white boxs content needs to be what would be related to the Profile menu item. How do I go about this? What would be the best practice when it comes to showing multiple content on a site? I've watched the video about multiple Content Place Holders, but I never really got it to work. I can't get a page to display in the NavigationPlaceHolder (the placeholder I put in the white box), but thats because the actual page is Frontpage.aspx and not WhateverIsInThenavigationPlaceHolder.aspx. If I go to the mysite.dk/WhateverIsInTheNavigationPlaceHolder.aspx it shows up fine. What have I missed here? :) Thanks in advance! If my question is not clear in some ways, please tell me and I will try to explain it better. All the best, Bo

  • In OpenRasta, how do I configure a URI where I get "the remainder of the path" as a single string?

    - by Daniel Earwicker
    Normally in OpenRasta there is some configuration like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/customers/region/{region}") ... // and so on ... where the {region} part of the path is automatically mapped to a string parameter in the handling method. So if the user hits: http://server/customers/region/emea Then the handler method is passed the string "emea". As well as doing this, I'd like to register a handler with something like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/someotherthing/*") ... // and so on In this imaginary syntax, the asterisk would mean "take the rest of the path, including slashes, to be a single string parameter to pass to the handling method". And so if the user hits: http://server/someotherthing/how/about/this?that=other Then my handler method receives a string parameter: how/about/this?that=other Is such a thing possible in OpenRasta? In Sinatra (Ruby) I'd use a regular expression to do exactly this.

  • Robust unit-testing of HTML in PHP

    - by asbja
    I'm adding unit-tests to an older PHP codebase at work. I will be testing and then rewriting a lot of HTML generation code and currently I'm just testing if the generated strings are identical to the expected string, like so: (using PHPUnit) public function testConntype_select() { $this->assertEquals( '<select><option value="blabla">Some text</option></select>', conntype_select(1); // A value from the test dataset. ); } This way has the downside that attribute ordering, whitespace and a lot of other irrelevant details are tested as well. I'm wondering if there are any better ways to do this. For example if there are any good and easy ways to compare the generated DOM trees. I found very similar questions for ruby, but couldn't find anything for PHP.

  • Just messed up a server misusing chown, how to execute it correctly?

    - by Jack Webb-Heller
    Hi! I'm moving from an old shared host to a dedicated server at MediaTemple. The server is running Plesk CP, but, as far as I can tell, there's no way via the Interface to do what I want to do. On the old shared host, running cPanel, I creative a .zip archive of all the website's files. I downloaded this to my computer, then uploaded it with FTP to the new host account I'd set up. Finally, I logged in via SSH, navigated to the directory the zip was stored in (something like var/www/vhosts/mysite.com/httpdocs/ and ran the unzip command on the file sitearchive.zip. This extracted everything just the fine. The site appeared to work just fine. The problem: When I tried to edit a file through FTP, I got Error - 160: Permission Denied. When I Get Info for the file I'm trying to edit, it says the owner and group is swimwir1. I attemped to use chown at this point to change owner - and yes, as you may be able to tell, I'm a little inexperienced in SSH ;) luckily the server was new, since the command I ran - chown -R newuser / appeared to mess a load of stuff up. The reason I used / on the end rather than /var/www/vhosts/mysite.com/httpdocs/ was because I'd already cded into their, so I presumed the / was relative to where I was working. This may be the case, I have no idea, either way - Plesk was no longer accessible, although Apache and things continued to work. I realised my mistake, and deciding it wasn't worth the hassle of 1) being an amateur and 2) trying to fix it, I just reprovisioned the server to start afresh. So - what do I do to change the owner of these files correctly? Thanks for helping out a confused beginner! Jack

  • Filling SWT table object using a separated thread class ...

    - by erlord
    Hi all I've got a code snippet by the swt team that does exactly what I need. However, there is a part I want to separate into another class, in particular, the whole inline stuff. In response to my former question, it has been suggested that Callable should be used in order to implement threaded objects. It is suggested to make use of an implementation of runnable or better callable, since I do need some kind of return. However, I don't get it. My problems are: In the original code, within the inline implementation of the method run, some of the parents objects are called. How would I do this when the thread is separated? Pass the object via the C'tor's parameter? In the original code, another runnable object is nested within the runnable implementation. What is it good for? How to implement this when having separated the code? Furthermore, this nested runnable again calls objects created by the main method. Please, have mercy with me, but I am still quite a beginner and my brain is near collapsing :-( All I want is to separate all the threaded stuff into another class and make the program do just the same thing as it already does. Help please! Again thank you very much in advance for any useful suggestions, hints, examples etc... Regs Me

  • Implementing "Generator" support in a custom language

    - by Roger Alsing
    I've got a bit of fettish for language design and I'm currently playing around with my own hobby language. (http://rogeralsing.com/2010/04/14/playing-with-plastic/) One thing that really makes my mind bleed is "generators" and the "yield" keyword. I know C# uses AST transformation to transform enumerator methods into statemachines. But how does it work in other languages? Is there any way to get generator support in a language w/o AST transformation? e.g. Does languages like Python or Ruby resort to AST transformations to solve this to? (The question is how generators are implemented under the hood in different languages, not how to write a generator in one of them)
