• Change .NET Framework version of application pool to 3.5?

  - by Sean Sexton

  I've installed .NET Framework 3.5 SP1 on web server (Server 2008 Enterprise), so running IIS 7.0. I want to change the version of .NET Framework used by an existing site. So I right-click on appropriate Application Pool and selected Edit Application Pool. The .NET Framework dropdown does not include an explicit entry for framework 3.5, but just 2.0.50727. Does anyone know off the top of their head--is this just because the version of the core RTL in 3.5 is still 2.0? Or do I need to do something additional to get IIS to see version 3.5? (Did try restarting IIS). Thanks!

• jQuery effect on iframe parent document

  - by Jabes88

  Just wondering if anyone else has experienced this or knows why I am getting an error. I'm using javascript from within an iframe to call a parent dom element then use jQuery UI's effect core to shake it. Here is an example: $(document).ready(function(){ if ($("form").length>0) { $("form").submit(function(){ var oParentDoc = $(parent.document).find("div#element"); var action = $(this).attr("action"); var postdata = $(this).serialize(); $(oParentDoc).addClass("loading"); $.post(action,postdata,function(data){ $(oParentDoc).removeClass("loading").effect("shake",{"times":3,"distance":10},60); }); return false; }); } }); It works without the effect, but when I use an effect it gives me this error: uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMCSSStyleDeclaration.getPropertyValue]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" Thanks in advance for any insight :)

• Android x86 porting, unable to make it work

  - by Mr G

  I'm kind of new to the whole porting issue and I got to it because of the slowness in the emulator provided with the Android SDK. I downloaded the android-x86-3.2-RC2-eeepc and android-x86-3.2-RC2-tegav2 ISO-es (from this site) and tried them on the VirtualBox but have no internet connection on the eeepc version and the tegev2 wont event start. I tried the VirtualBoxHowTo but got nothing, on both Windows and Linux platforms. the only thing I managed to understand is that to use this on a VM you need to build it for VM. Can anyone help me on this? P.S.: I need the HoneyComb version (3.2) and the pc I have is a AMD 6 core on and Asus Crosshair Extreme motherboard, Windows 7 or Ubunutu 11.10. (both OS are 64bit)

• How stable or unstable is symfony 2.0 ?

  - by Doron

  Well, I know it's a preview, and I know it says that it's not yet ready for production, and yet I dare ask the question. I need to start building a pretty big application, which is planned to go live at around sep-oct 2010. Lets say I will not release the application to production until the stable version of symfony 2.0 will be released - is it a good idea (well, I'll settle for a viable idea) for me to start building the application using the 2.0 version ? How big is the chance I will need to rewrite/replace code I've written due to core changes in the framework ? Thanks. Edit: the other option right now, is to use symfony 1.4. I have thought and tried Zend Framework, but I refuse to re-invent each and every module, which will cost me a lot of programming hours (if not days/weeks).

• How to select the first element of a set with JSTL?

• JSF : How to refresh required field in ajax request

  - by Tama

  Ok, here you are the core problem. The page. I have two required "input text". A command button that changes the bean value and reRenderes the "job" object. <a4j:form id="pervForm"> SURNAME:<h:inputText id="surname" label="Surname" value="#{prevManager.surname}" required="true" /> <br/> JOB:<h:inputText value="#{prevManager.job}" id="job" maxlength="10" size="10" label="#{msg.common_label_job}" required="true" /> <br/> <a4j:commandButton value="Set job to Programmer" ajaxSingle="true" reRender="job"> <a4j:actionparam name="jVal" value="Programmer" assignTo="#{prevManager.job}"/> </a4j:commandButton> <h:commandButton id="save" value="save" action="save" class="HATSBUTTON"/> </a4j:form> Here the simple manager: public class PrevManager { private String surname; private String job; public String getSurname() { return surname; } public void setSurname(String surname) { this.surname = surname; } public String getJob() { return job; } public void setJob(String job) { this.job = job; } public String save() { //do something } } Let's do this: Write something on the Job input text (such as "teacher"). Leave empty the surname. Save. Validation error appears (surname is mandatory). Press "Set job to Programmer": nothing happens. Checking the bean value, I discovered that it is correctly updated, indeed the component on the page is not updated! Well, according to the JBoss Docs I found: Ajax region is a key ajax component. It limits the part of the component tree to be processed on the server side when ajax request comes. Processing means invocation during Decode, Validation and Model Update phase. Most common reasons to use a region are: -avoiding the aborting of the JSF lifecycle processing during the validation of other form input unnecessary for given ajax request; -defining the different strategies when events will be delivered (immediate="true/false") -showing an individual indicator of an ajax status -increasing the performance of the rendering processing (selfRendered="true/false", renderRegionOnly="true/false") The following two examples show the situation when a validation error does not allow to process an ajax input. Type the name. The outputText component should reappear after you. However, in the first case, this activity will be aborted because of the other field with required="true". You will see only the error message while the "Job" field is empty. Here you are the example: <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich"> <style> .outergridvalidationcolumn { padding: 0px 30px 10px 0px; } </style> <a4j:outputPanel ajaxRendered="true"> <h:messages style="color:red" /> </a4j:outputPanel> <h:panelGrid columns="2" columnClasses="outergridvalidationcolumn"> <h:form id="form1"> <h:panelGrid columns="2"> <h:outputText value="Name" /> <h:inputText value="#{userBean.name}"> <a4j:support event="onkeyup" reRender="outname" /> </h:inputText> <h:outputText value="Job" /> <h:inputText required="true" id="job2" value="#{userBean.job}" /> </h:panelGrid> </h:form> <h:form id="form2"> <h:panelGrid columns="2"> <h:outputText value="Name" /> <a4j:region> <h:inputText value="#{userBean.name}"> <a4j:support event="onkeyup" reRender="outname" /> </h:inputText> </a4j:region> <h:outputText value="Job" /> <h:inputText required="true" id="job1" value="#{userBean.job}" /> </h:panelGrid> </h:form> </h:panelGrid> <h:outputText id="outname" style="font-weight:bold" value="Typed Name: #{userBean.name}" /> <br /> </ui:composition> Form1: the behaviour is incorrect. I need to fill the job and then the name. Form2: the behaviour is correct. I do not need to fill the job to see the correct value. Unfortunately using Ajax region does not help (indeed I used it in a bad way ...) because my fields are both REQUIRED. That's the main different. Any idea? Many thanks.

• What is the best PHP framework for building a website around a heavily relational PostgreSQL databas

  - by Kenaniah

  First of all, the framework of choice needs to have excellent support for PostgreSQL. I don't care about MySQL because it doesn't have half of the features the application I will be porting requires. (And when I say excellent support, I mean that their approach to database drivers has not been solely trained in MySQL). The ideal framework: Should take full advantage of PHP 5.3 and PostgreSQL 8.4 features Should support new technologies such as OpenID and social networking Should support complex relationships between database relations Should have an intelligent validation system Should have a basic library of helpful views (such as pagination, navigation, etc) Should probably be MVC based Should have excellent documentation and an active development community Should namespace classes intelligently What I'm looking for might be more of a library of utilities, as I really don't want to be restricted by the framework in what I can and can not do. I have my own small library of core classes that take care of business logic, and I will most likely want to integrate those with the new framework as well. Thanks!

• Are there any other Java schedulers besides Quartz(FOSS) and Flux(Commercial)

  - by mP

  I am interested in finding out about other job scheduling packages besides Quartz and Flux. Given the plethora of web frameworks i find it perculiar that there is really only one scheduler. Are there others that perhaps are very much unknown/unpopular ? Spring Batch Not really a scheduling solution but rather a batch job coordinator etc. http://static.springsource.org/spring-batch/faq.html#schedulers How does Spring Batch differ from Quartz? Is there a place for them both in a solution? Spring Batch and Quartz have different goals. Spring Batch provides functionality for processing large volumes of data and Quartz provides functionality for scheduling tasks. So Quartz could complement Spring Batch, but are not excluding technologies. A common combination would be to use Quartz as a trigger for a Spring Batch job using a Cron expression and the Spring Core convenience SchedulerFactoryBean .

• Resizing uploaded files in django using PIL

• Programmatically sync the db in Django

  - by Attila Oláh

  I'm trying to sync my db from a view, something like this: from django import http from django.core import management def syncdb(request): management.call_command('syncdb') return http.HttpResponse('Database synced.') The issue is, it will block the dev server by asking for user input from the terminal. How can I pass it the '--noinput' option to prevent asking me anything? I have other ways of marking users as super-user, so there's no need for the user input, but I really need to call syncdb (and flush) programmatically, without logging on to the server via ssh. Any help is appreciated.

• How do I add a reference to a Web Application Project in an Associated Class Library?

  - by 5arx

  I'm working on an internet application that has been set up as a web SITE project (I know...) in Visual Studio. I need to add additional features/functionality so have added a class library to the project and referred to it in the main web site project. The issue now arises because I need to make use of core objects which live inside the App_Code directory in the web site project but this project doesn't appear to expose its DLL like web app/ code library projects do. Because of this I can't add a reference to the web site project in the class library to leverage the common site-wide code/objects. I can't move the stuff out of App_Code so I'm looking for a way to refer to the website project dll from the new class library. Can anyone suggest a workaround? All help v. gratefully received :-)

• Record locking problem between linux and Windows

  - by PabloG

  I need to run a bunch of old DOS FoxPro / Clipper applications in linux under DOSEMU. The programs access their "databases" located on a network server (could be a Windows or Linux server) Actually, the programs ran fine, but I cannot manage to make the record locking work as supposed: I can run a program in two terminals (or the server and any terminal for instance) and lock the same record in both. Now, I'm using Tiny Core Linux as terminal and Windows XP as server, accesing the shared files via CIFS and the latest DOSEMU (1.4.0), but I tried with various combinations of server (Ubuntu 7 to 9, Damn Small Linux, XP) <- protocol (CIFS, samba, various versions of smbclient) <- client (same as server) with no luck I tried to configure the server part to work without oplocks in samba (after reading the entire O'Reilly Samba book locking chapter in http://oreilly.com/catalog/samba/chapter/book/ch05_05.html ) and in XP (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\UseOpportunisticLocking = 0) but the problem persist. Any ideas? TIA, Pablo

• WordPress: don't show 404 when no posts exist

  - by philfreo

  Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.

• Configuring IoC container from modules/plug-ins ?

  - by rouen

  Hi guys, i am in big dilema.. I am working on highly modular web app in ASP.NET MVC 2 (in fact, core will be super lightweight, all work on modules/plugins). I found MEF pretty useful for modules discovery, but i dont want to us it as IoC container. There is pretty good chance that I will need advanced features of "true" IoC container, so I would like to use Unity. And here is the problem : how to allow modules to configure container (programatically) = register their own types (mvc controllers, custom implementations of services...) at application start without making hard dependency on Unity in all modules ? I know about Common Service Locator project, and it seems pretty good, but this interface co container only allows resolving types, not registering them (afaik). I really hope you can understand my point, I know my english is terrible (I am from non english speaking country :) Thanks a lot !

• Space bar and arrow keys on Radio buttons trigger TypeError: Error #1009

  I've just discovered a bug in my app, it looks like a Flash player bug, i would like to know if anyone has found a workaround or something. I've some radio buttons groups in my app. If I press the arrow keys while holding the spacebar pressed, it ends up triggering TypeError: Error #1009: Cannot access a property or method of a null object reference. at fl.controls::LabelButton/drawIcon() at fl.controls::LabelButton/draw() at fl.controls::RadioButton/draw() at fl.core::UIComponent/callLaterDispatcher() If found this thread that describes my same situation. Do you think there's any workaround for this? Is it really a flash bug?

• Why many "normal" string in my flashlog file

  - by randy

  I suddenly find that there are many "normal" trace in my file flashlog.txt (supposed at your Window's location:{SysDrive}:\Documents and Settings{yourName}\Application Data\Macromedia\Flash Player\Logs). normal normal normal normal normal normal 1/10/2011 15:32:13.008 [INFO] org.spicefactory.parsley.core.view.impl.DefaultViewManager Add view root: null/flash.display::Stage normal normal normal But when I run the application with the FlashBuilder, the logging in the consul page is ok, it doesn't include any "normal" String. I am very confused by this, I thought that the output of the flashlog.txt file should be the same as that of the consul of FlashBuilder.And I don't think I have added such a stupid trace in my code. The question is how can I find out where these "normal" trace come from and how to remove it. This problem is resolved by restarting the computer as suggested.

• Erlang on a JVM/CLR

  - by Fortyrunner

  I've just started reading Joe Armstrongs book on Erlang and listened to his excellent talk on Software Engineering Radio. Its an interesting language/system and one whose time seems to have come around with the advent of multi-core machines. My question is: what is there to stop it being ported to the JVM or CLR? I realise that both virtual machines aren't setup to run the lightweight processes that Erlang calls for - but couldn't these be simulated by threads? Could we see a lightweight or cutdown version of Erlang on a non Erlang VM?

• Multi-process builds in Visual Studio 2010: Worth it?

  - by coryr

  I've started testing our C++ software with VS2010 and the build times are really bad (30-45 minutes, about double the VS2005 times). I've been reading about the /MP switch for multi-process compilation. Unfortunately, it is incompatible with some features that we use quite a bit like #import, incremental compilation, and precompiled headers. Have you had a similar project where you tried the /MP switch after turning off things like precompiled headers? Did you get faster builds? My machine is running 64-bit Windows 7 on a 4 core machine with 4 GB of RAM and a fast SSD storage. Virus scanner disabled and a pretty minimal software environment.

• Why implement DB connection pointer object as a reference counting pointer? (C++)

  - by DVK

  At our company one of the core C++ classes (Database connection pointer) is implemented as a reference counting pointer. To be clear, the objects are NOT DB connections themselves, but pointers to a DB connection object. The library is very old, and nobody who designed is around anymore. So far, nether I, nor any C++ experts in the company that I asked have come up with a good reason for why this particular design was chosen. Any ideas? It is introducing some problems (partially due to awful reference pointer implementation used), and I'm trying to understand if this design actually has some deep underlying reasons? The usage pattern these days seems to be that the DB connection pointer object is returned by a DB connection manager class, and it's somewhat unclear whether DB connection pointers were designed to be able to be used independently of DB connection manager.

• Cakephp Localization, Cannot Change language when DEFAULT_LANGUAGE is set

  - by ion

  I am confused :) I'm using the p18n component in cakephp found here: http://www.palivoda.eu/2008/04/i18n-in-cakephp-12-database-content-translation-part-2/ This component requires me to set in core.php the following constant: define("DEFAULT_LANGUAGE", 'eng') However when this is set I cannot change the language using: Configure::write('Config.language', 'eng'); At the moment, into my knowledge, the only way to change the locale of my static content is the use of the Configure::write. But for the dynamic content to change through the use of the p28n component I must have the DEFINE_LANGUAGE constant set to a value. This is all very confusing. Any help will be much appreciated.
