• Is Prince the best way to create PDFs in Ruby on Rails?

  - by Angela

  After several Google searches, it appears that the way to create PDFs in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the whats and hows.

• In Zend studio, how to tell the ide the type of a variable, so I have auto completion?

  - by Itay Moav

  In php we use includes. So variables defined in one file and then their scope spans included files too. Zend studio has no idea how to get the type of the variable I am using inside an included file, this is very annoying when the variable type is a big class. Is there a way to hint the ide about variable types? in included files?

• Why is giving a fixed width to a label an accepted behavior?

  - by kemp

  There are a lot of questions about formatting forms so that labels align, and almost all the answers which suggest a pure CSS solution (as opposed to using a table) provide a fixed width to the label element. But isn't this mixing content and presentation? In order to choose the right width you basically have to see how big your longest label is and try a pixel width value until "it fits". This means that if you change your labels you also have to change your CSS.

• Again, what version control system to choose?

  - by Ivan

  Please excuse me for probably a newbie hundred-times-chewed question. I have no experience with version control systems except of using Visual Source Safe in a project done by 2 people sitting in front of each other (which has shown VSS quite sack of boulders, not anything useful). Right now I am looking to grok-in using some modern VCS. Here are the preferences in descending priority order: Platform-agnostic. Pretty pleasant to use With Visual Studio 2010 on Windows as well as With NetBeans 6.9 and Eclipse 3.6 on Linux and Mac. Convenient and efficient for mutually-dependent projects done by teams of 1-10 and consisting of files of quite a diverse selection of types. Including early-stage projects with unstable design and experimenting. Modern. As fresh and future-technology-feature-rich as possible. Free & open-source. Should I take a closer look at SVN, Mercurial, GIT, Bazaar, or something else?

• Sending an int array through Winsocks

  - by seed

  I'm trying to send an int array through Winsocks. I might be wrong, but I'm pretty sure only a char* is supported so I'm kind of stuck on how to do this properly. There are also problems with little/big edian, so what would be a good way to do this? I've already asked a question of converting int array to char but it was recommended to start a new thread on this in the networking section instead.

• Best C++ Linux IDE [closed]

  - by Idan

  Possible Duplicate: Best unix/linux C++ debuger/IDE ? Hey, I've been searcing and reading about a good Linux C++ IDE, and couldn't set my mind on the right one. I've been using Eclipse with the C++ pluging , for C development, for the last couple months, but I found it not very useful, especially the debugging process that was quite annoying. I love Vistal Studio, so I'm looking for something really close to it. I need an IDE that will provide me, among other things: - rich debugging options - easy to use graphical designer - underscores error/warning (before I compile - like eclipse has) - Intellisense and more... Any suggestion? Maybe NetBeans?

• 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.

• Disabling javascript in specific block/div (containing suspect HTML) ?

  - by T4NK3R

  Is it, in any way, possible to disable the browsers execution of script inside a block/section/element ? My scenario is, that I'm letting my (future) users create "rich content" (using CK-editor). Content that wil later be shown to other users - with all the dangers that imply: xss, redirection, identity theft, spam and what not... I've, more or less, given up on trying to "sanitize" the incomming XHTML, after seeing how many known "vectors of attack" there are: http://ha.ckers.org/xss.html What I'm really looking for is something like: < div id="userContent"< scriptOFF suspect HTML < /scriptOFF< /div

• I'm tired of JButtons, how can I make a nicer GUI in java ?

  - by Jules Olléon

  So far I've only build "small" graphical applications, using swing and JComponents as I learned at school. Yet I can't bear ugly JButtons anymore. I've tried to play with the different JButton methods, like changing colors, putting icons etc. but I'm still not satisfied. How do you make a nicer GUI in java ? I'm looking for not-too-heavy alternatives (like, without big frameworks or too complicated libraries).
