• different levels in code igniter?

  - by ajsie

  im all new to framework. so the structure of code igniter looks like: system system/application the system folder is code igniter's base folder right? so if they in the future releases a new version i just put application in the new system folder and its upgraded right? does this mean that i shouldn't put new files and so on in the system folder? cause some code could be used for other applications and i want to put them under the current application im developing, not inside the application folder. i want my application's classes to extend my base system's classes which in turn extend code igniter's base system class. so there are 3 levels. so how could i accomplish this? where to put the system level between CI and my application?

  - by Rishabh

  Hi, I am using Net Beans for developing an application on S60. I made one page for user authentication and using .net wcf service to authenticate user. i am able to send data on .net service by HttpGet method but not able to get response back on java page. I have tested it on fiddler with this url its working fine and returning response code 200, but not getting response code by java code. Following code i am using. Is some thing wrong here ? httpConn = (HttpConnection)Connector.open(url); httpConn.setRequestMethod(HttpConnection.GET); httpConn.setRequestProperty("User-Agent", "Profile/MIDP-2.1 Confirguration/CLDC-1.1"); int respCode = httpConn.getResponseCode(); Thanks Rishabh

• Magento Design Patterns

  - by JonB

  Magento, IMHO, represents a PHP system that is built on well thought-out coding principles - reuseable design patterns being one of them. In terms of an example of a PHP system, I think it can be considered pretty cutting edge and therefore worth considering from an architectural point of view. As I understand it, there are many design patterns that are available to the OOP developer. Seeing such patterns being put to use in an open-source system such as Magento allows a developer to view examples of such patterns in real use and in situ, rather than in examples that can sometimes be rather achedemic, and even a little misleading. As such, I am wondering what patterns, other than the ones I have listed below, Magento programmers have used when developing for Magento. As a note, I understand that some of these patterns are in place as a consequence of being built on the Zend Framework, MVC / Front Controller being a couple of them, The obvious ones are: Factory: $product = Mage::getModel('catalog/product'); Singleton: $category = Mage::getSingleton('catalog/session'); Registry: $currentCategory = Mage::registry('current_category');

• how to add special class for labels and errors on zend form elements?

  - by user1400

  hello how we could add a special class for labels and errors for a zend-form-element for example html output code before add classes <dt id="username-label"><label for="username" class="required">user name:</label></dt> <dd id="username-element"> <input type="text" name="username" id="username" value="" class="input" /> <ul class="errors"><li>Value is required and can't be empty</li></ul></dd> and code after we add classes <dt id="username-label"><label for="username" **class="req-username"**>user name:</label></dt> <dd id="username-element"> <input type="text" name="username" id="username" value="" class="input" /> <ul **class="err-username"**><li>Value is required and can't be empty</li></ul></dd> thanks

• page not show after issuing zf command

  - by Nazmin

  hello guys, just simple question, recently i have setup a web server to build project using zend framework, after setup and see those welcome page saying that you are creating websites powered by zendframework, then i try issuing command, $ zf create controller alert i get the message that saying that i've successfully create controller, view and so on, but when i try to navigate to the page by URL, ex: www.mywebapp.com/alert the page is broken, i've check those tuts but none of them showing this case. can some one define which step i've skip? update: (25/5/2010) so i've found that there is no problem, is just that i've not configured properly my route to my web apps, so i have to type URL like this: www.mywebapp.com/index.php/alert how am I going to change this? i mean i want to explode "index.php" out of URL.

• Does malloc() allocate a contiguous block of memory?

  - by user66854

  I have a piece of code written by a very old school programmer :-) . it goes something like this typedef struct ts_request { ts_request_buffer_header_def header; char package[1]; } ts_request_def; ts_request_buffer_def* request_buffer = malloc(sizeof(ts_request_def) + (2 * 1024 * 1024)); the programmer basically is working on a buffer overflow concept. I know the code looks dodgy. so my questions are: Does malloc always allocate contiguous block of memory ?. because in this code if the blocks are not contiguous , the code will fail big time Doing free(request_buffer) , will it free all the bytes allocated by malloc i.e sizeof(ts_request_def) + (2 * 1024 * 1024), or only the bytes of the size of the structure sizeof(ts_request_def) Do you see any evident problems with this approach , i need to discuss this with my boss and would like to point out any loopholes with this approach

• Transferring Data Between Server and Client (Mobile)

  - by Byron

  Scenario: Client (Mobile) - .Net CF 2.0, SQL CE 3.0 Server - .Net 2.0, SQL Server 2005, Web Service Client and Server database schemas differ. From server - only certain columns from certain tables need to be synced. From client - everything will need to be synced once client has made changes. Client will continually poll a web service to download and upload data. A framework will be developed to package and unpackage data, used by both client and server. How would you develop the packaging and unpackaging? Use datasets, serialise strongly typed objects? All suggestions welcome. Thanks

• PHP - Frameworks, ORM, Encapsulation.

  - by Ian

  Programming languages/environments aside, are there many developers who are using a framework in PHP, ORM and still abide by encapsulation for the DAL/BLL? I'm managing a team of a few developers and am finding that most of the frameworks require me to do daily code inspection because my developers are using the built in ORM. Right now, I've been using a tool to generate the classes and CRUD myself, with an area for them to write additional queries/functions. What's been happening though, is they are creating vulnerabilities by not doing proper checks on data permission, or allowing the key fields to be manipulated in the form. Any suggestions, other than get a new team and a new language (I've seen Python/Ruby frameworks have the same issues).

• How does TopCoder evaluates code?

  - by Carlos

  If you are familiar with TopCoder you know that your source-code gets a final "grade/points" this depends on time, how many compiles, etc, one of the highest weighted being performance. But how can they test that, is there some sort of simple code (java or c++) to do it that you could share for me to evaluate and hopefully write my own to test the programs I write for University? This is sort of a follow up question to this one where I ask if shorter code results in best performance. P.S: Im interested in both of how topcoders knows performance and writing code to test performance.

• preg_replace on xss code

  Can this code help to sanitize malicious code in user submit form? function rex($string) { $patterns = array(); $patterns[0] = '/=/i'; $patterns[1] = '/javascript:/i'; $replacements = array(); $replacements[0] = ''; $replacements[1] = ''; return preg_replace($patterns, $replacements, $string); I have included htmlentities() to prevent XSS on client side, is all the code shown is safe enough to prevent attack?

• tool to auto-format R code

  - by Keith

  Is there any tool (editor, script, whatever...) available that can automatically reformat R code? It does not need to be customizable but it must be able to recognize statements separated by either semicolons or newlines since this code has both. If it can put all statements on a separate line, consistently indent code blocks and consistently place braces I will be very happy.

• What do you do when one thinks the code isn't complicated enough?

  - by Chris

  After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?

• Agile Uploader error code 2101?

  - by adamwstl

  I'm trying to install Agile Uploader, but keep running into an error code 2101 (no other message besides that.) Any idea what error code "2101" means? Whenever I try to submit/upload (when I call agileUploaderSubmit()), nothing seems to happen and with Firebug mode on, all the log prints out is that code. I can't find anything that tells me what it means. Thanks

• How to dynamically order many-to-many relationship in JPA or HQl?

  - by Indrek

  I have a mapping like this: @ManyToMany(cascade = CascadeType.PERSIST) @JoinTable( name="product_product_catalog", joinColumns={@JoinColumn(name="product_catalog", referencedColumnName="product_catalog")}, inverseJoinColumns={@JoinColumn(name="product", referencedColumnName="product")}) public List<Product> products = new ArrayList<Product>(); I can fetch the products for the catalog nicely, but I can't (dynamically) order the products. How could I order them? I probably have to write a many-to-many HQL query with the order-by clause? I though of passing the orderBy field name string to the query, or is there a better solution? Tables are: products, product_catalog, product_product_catalog (associative table) P.S. Using Play! Framework JPASupport for my entities.

• How to Use Eclipse to Debug JNI code (Java & C/C++)

  - by tkryger

  While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI Environments Mariot Chauvin's Summer of Code Project: Support Seamless Debugging between JDT & CDT Unfortunately, one claims to be pre-release quality and the other is currently unmaintained. Are there any plug-ins that bring mixed mode debugging functionality to Eclipse in a reliable way or should I continue to use two separate debuggers?

• ANTLR - Embedding Java code, evaluate before or after?

  - by wvd

  Hello all, I'm writing a simple scripting language on top of Java/JVM, where you can also embed Java code using the {} brackets. The problem is, how do I parse this in the grammar? I have two options: 1] Allow everything to be in it, such as: [a-z|a-Z|0-9|_|$], and go on 2] Get an extra java grammar and use that grammar to parse that small code (is it actually possible and efficient?) Since option 2] is basically a double-check since when evaluating java code it's also being checked. Now my last question is -- is way that can dynamically execute java code also with objects which have been created at runtime? Thanks, William van Doorn

• Zend without Database

  - by dbemerlin

  Hi, i googled for an hour now but maybe my Google-Fu is just too weak, i couldn't find a solution. I want to create an application that queries a service via JSON requests (all data and backend/business logic is stored in the service). With plain PHP it's simple enough since i just make a curl request, json_decode the result and get what i need. This already works quite well. A request might look like this: Call http://service-host/userlist with body: {"logintoken": "123456-1234-5678-901234"} Get Result: { "status": "Ok", "userlist":[ {"name": "foo", "id": 1}, {"name": "bar", "id": 2} ] } Now we want to get that into the Zend Framework since it's a hobby project and we want to learn about Zend. The problem is that all information i could find use a Database. Is there even a way to create a Zend Project that does not use a Database? And how can i write a model that represents the actions instead of objects and object-relations?

• TFS 2008 checks out code automatically on edit

  - by Jangwenyi

  I am working on a Visual Studio 2008 project that is already added to TFS server. I am not sure which settings and policies have been configured for the TFS (this is done by a separate dept, not developers) Every time I make an edit to a code file , the file is checked out automatically (without explicitly checking out the code file myself) Please help me locate this setting or policy because it is not very useful at the moment. Sometime you want to make a local change to try out something, and not necessarily check out the code....

• How to change Zend_Db_Table name within a Model to insert in multiple tables

  - by jwhat

  Using Zend Framework, I've created a Model to insert a record into a database. My question is, after $this->insert($data) how can I switch the active table so that I can insert a record into another table? Here's my code so far: class Model_DbTable_Foo extends Zend_Db_Table_Abstract { protected $_name = 'foo'; public function addFoo($params) { $data = array( 'foo' => $params['foo'], ); $this->insert($data); $foo_id = $this->getAdapter()->lastInsertId(); $data2 = array( 'bar' => $params['bar'] ); // I need to change the Db Table name here. $this->insert($data2); $bar_id = $this->getAdapter()->lastInsertId(); } }

• Foolproof way to check for nonzero (error) return code in windows batch file

  - by Pat

  Intro There's a lot of advice out there for dealing with return codes in batch files (using the ERROLEVEL mechanism), e.g. Get error code from within a batch file ERRORLEVEL inside IF Some of the advice is to do if errorlevel 1 goto somethingbad, while others recommend using the %ERRORLEVEL% variable and using ==, EQU, LSS, etc. There seem to be issues within IF statements and such, so then delayedexpansion is encouraged, but it seems to come with quirks of its own. Question What is a foolproof (i.e. robust, so it will work on nearly any system with nearly any return code) way to know if a bad (nonzero) code has been returned? My attempt For basic usage, the following seems to work ok to catch any nonzero return code: if not errorlevel 0 ( echo error level was nonzero )
