  • 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

  • Redundant code in exception handling

    - by Nicola Leoni
    Hi, I've a recurrent problem, I don't find an elegant solution to avoid the resource cleaning code duplication: resource allocation: try { f() } catch (...) { resource cleaning code; throw; } resource cleaning code; return rc; So, I know I can do a temporary class with cleaning up destructor, but I don't really like it because it breaks the code flow and I need to give the class the reference to the all stack vars to cleanup, the same problem with a function, and I don't figure out how does not exists an elegant solution to this recurring problem.

    - 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

  • Is It Possible To Spring Autowire the same Instance of a protoype scoped class in two places

    - by Mark
    Hi ** changed the example to better express the situation i am using spring 2.5 and have the following situation @Component @Scope("prototype") Class Foo { } class A { @Autowired Foo fooA; } class B { @Autowired Foo fooB; } class C { @Autowired Foo fooC; } i am trying to understand if there is some way to use @Autowired and bind the same instance of FOO onto fooA and fooB while binding a different instance to fooC i understand that if the scope of FOO will be singleton it will work but i am wandering if there is a way to achieve the same goal while using a protoype scope. also please explain is this the correct usage of the autowiring concept ? am i trying to abuse the spring framework purpose

  • 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?

  • 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.

  • 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

  • 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.

  • 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?

  • 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

  • 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?

  • 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.

  • Is there any performance overhead in using RaiseEvent in .net

    - by Sachin
    Is there any performance overhead in using RaiseEvent in .net I have a code which is similar to following. Dim _startTick As Integer = Environment.TickCount 'Do some Task' Dim duration As Integer = Environment.TickCount - _startTick Logger.Debug("Time taken : {0}", duration) RaiseEvent Datareceived() Above code returns Time Taken :1200 Time Taken :1400 But if remove RaiseEvent it returns Time Taken :110 Time Taken :121 I am surprised that the raiseevent is called after the logging of time taken. How it effects total time taken. I am working on Compact framework. Update: In the Eventhandler I had given a MsgBox. When I removed the message box it is now showing time taken as 110,121,etc i.e. less that 500 milliseconds. If I put the Msgbox back in eventhandler it shows 1200,1400,etc i.e. more that a second. More surprised now.(Event is raised after the logging part)

  • 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(); } }

  • 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 call a view method to a model in zendframework

    - by Awais Qarni
    hello I just want to ask whether we can call a view method to a model? I know that we can call it on our controller in zend framework. Like if I want to call the url method of view on my controller I can call it like this $this->view->url(array(),''); and on the view we just can call it by $this->url(array(),''); But When I tried to call the same method on my model by $this->view->url(array(),''); it generates an error of call to undefined method url. Now I want to ask whether it is possible to call view method to a model? If yes then how? What Am I doing wrong. Thanks

  • OpenNETCF.Net.Ftp Behaving Flaky

    - by gnomixa
    I tried posting on their boards (authors of this library), however it literally takes months for them to reply when it comes to the free software (can't blame them). But anyways I have found that this library is behaving weirdly - for instance, a major problem with my application is when someone is trying to sign in (through FTP), they provide a correct login and mistype the password, no reply is received from FTP server. I tried doing the same from command window just to verify that it's not the FTP server's fault; and FTP commands were received instantaneously. It almost looks as though this library eats the commands. The same actions often times will yield different results. Can anyone recommend a stable, reliable library to use with Compact framework? Or shed some light on this issue...?

  • 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
