• How can I get my div id to reload via ajax and jquery

  - by Matt Nathanson

  I'm creating a CMS using jQuery and AJAX. When I click, my "Add Campaign" buttom, it creates a unique client ID in the DB and on a hard reload, the new client shows up in its container. I am trying to use ajax to reload the container on the fly and I'm not having the exact luck i am hoping for. I can get it to reload, but it's like it's pulling in descriptions of each of the clients as well! function AddNewClient() { dataToLoad = 'clientID=' + clientID + '&addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $('#clientssidebar').html(html); }, error: function() { alert('An error occured!'); } }); };

• Under what circumstances would a Ruby $LOAD_PATH be acquired from a parent process?

  - by Dr Nic

  In my cucumber scenarios, if I call rake db:schema:load within a target Rails app folder, I get the cucumber process's $LOAD_PATH and not the Rails app's own Gemfile/load path. I think this is very weird. The consequence is that I get the following error: no such file to load -- rails/all I can't reproduce it outside of my cucumber scenario. ruby -rubygems -e "system 'rake -T'" works normally - the 'rake -T' has the application's own Gemfile-based $LOAD_PATH; and doesn't generate the error above. Can anyone think why a child process (rake -T or rake db:schema:load or rails runner...; invoked by either system, exec, %x[...] or backtick; would start with the parent processes' $LOAD_PATH (from the cucumber scenario's Gemfile) instead of its own $LOAD_PATH (from the Rails app's Gemfile)?

• How to find out the dimensionality of print paper in javascript

  - by tzador

  I am generating reports in HTML formats, and want to print them automatically using Qt (qt has a webkit based browser, and one can render its contents to a PDF file). I want to position the elements of the report depending on the target page size. For that i need to access the size of the paper (preferably in pixels). Since i am using webkit, it has all the latest html5 and css3 features. is there some api available to access printed page properties inside javascript. for example, would be nice to write: window.print_paper.width or window.print_paper.height Thank you in advance

• Modifiers in Makefile rule's dependency list

  - by gnu_maker

  The problem is fairly simple. I am trying to write a rule, that given the name of the required file will be able to tailor its dependencies. Let's say I have two programs: calc_foo and calc_bar and they generate a file with output dependent on the parameter. My target would have a name 'target_*_*'; for example, 'target_foo_1' would be generated by running './calc_foo 1'. The question is, how to write a makefile that would generate outputs of the two programs for a range of parameters?

• NoClassDefFoundError when running java tool under Xcode

  - by pancake

  Hi all, I'm trying to create a Java Tool by using Xcode. I've already changed my build.xml to have Xcode target java 1.6 and not 1.3 so I can use generics. I'm getting no build errors and using 'javac' and 'java' in the terminal works. Now I want it to work in Xcode as well. I keep getting the following error: Exception in thread "main" java.lang.NoClassDefFoundError: MyClass where 'MyClass' is the class containing the main method. It probably has something to do with the classpath, which as the build.xml prescribes is "${bin}". There is a bin folder in my project folder, and it contains all the .class files needed to run the program. If anybody could help me, it'd be great!

• TFS Automated Builds to Code Packages

  - by Adam Jenkin

  I would like to hear the best practices or know how people perform the following task in TFS 2008. I am intending on using TFS for building and storing web applications projects. Sometimes these projects can contain 100's of files (*.cs, *.acsx etc) During the lifetime of the website, a small bug will get raised resulting in say a stylesheet change, and a change to default.aspx.cs for example. On checking in these changes to TFS, and automated build would be triggered (great!), however for deploying the changes to the target production machine, I only need to deploy for example: style.css default.asx MyWebApplications.dll So my question is, can MSBuild be customized to generate a "code pack" of only the files which require deploying to the production server based on the changeset which cause the re-build?

• Maximizing the current window in javascript

  - by user349134

  Is there a way I can maximize a currently minimized window from Javascript? Here's my situation: I have a series of links that all target the same external window (e.g. "MyNewWindow"). When I click a link, a new window pops up. If I click another link, the page pops up in the same window as expected. If I minimize the "MyNewWindow" popup, I'd like to be able to click another link and have that window maximize. My approach was to put something on the onLoad part of the body so that when the page is refreshed it will automatically "maximize" if it is minimized. Note: Using window.MoveTo() and window.resizeTo() doesnt seem to do the trick (the window stays minimized). Thanks!

• Setting up separate ctags db's for C/C++ standard libs, boost, and third party libs

  - by Robert S. Barnes

  I want to set up separate ctags databases for various libraries in /usr/include/ for use with OmniCppComplete. The idea is to be able to pull in only the libraries needed for a particular project in the target language - C or C++. For example, I'd like to have one database for the standard C libraries, one for system libraries that might be used by either C or C++ programs ( sockets / networking comes to mind ) one for the standard C++ libs / STL / Boost, and then other databases for various third party libraries such as QT or glib. Then I could pull something in simply by typing set tags+= ~/.vim/somelib.tags in vim. I assume that everything related to the C++ stdlib and STL are in the /usr/include/c++ and that Boost is all in /usr/include/boost. Unfortunately it seems that the standard C libs and system libs are just kind of dumped directly into /usr/include/ with a variety of other stuff. How can I get a list of which files and directories belong to which libs? I'm on Ubuntu 8.04.

• Django admin proper urls inside listview

  - by hinnye

  Hi, My current target is to give users the chance to download CSV files from the admin site of my application. I successfully managed to create an additional column in the model's list view this way: def doc_link(self): return '<a href="files/%s">%s</a>' % (self.output, self.output) doc_link.allow_tags = True This shows the file name and creates the link, but sadly - because it's inside my 'searches' view - it has an URL: my_site/my_app/searches/files/13.csv. This is my problem, I would like to have my files stored in the admin media directory, like this: http://my_site/media/files/13.csv Does somebody know how to give url which points "outer" from the model's directory? Maybe somehow tell Django to use the ADMIN_MEDIA_PREFIX in the link? I'd really appreciate any help, thanks!

• Platform independent remote file editing

  - by Ressu

  I've been investigating possibilities on editing remote files from a website without having a need to download and upload the files manually while editing. So far I've ruled out WebDAV as a possibility since it is cumbersome to use on any platform (it either requires manual setup or works unreliably). Currently I'm looking in to various Applets, but they mostly target either uploading or downloading, not file editing. What I'm currently looking for is an applet that downloads the document, launches the application that is meant to open the file and then monitors the file for changes and uploads the changed file (either automatically or by prompting the user first). I know that I'm not alone with this scenario, so i'm looking for solutions that others have thought of.

• Open source jigsaw piece generator

  - by codecowboy

  Hi, Does anyone know of a C-based open source class / framework which can generate a random jigsaw puzzle from an image or generate a random puzzle template which could then be applied to an image? The puzzle pieces must have male and female notches/holes. There should be more than one template so that the puzzle does not become too easy. The target system is iOS / Mac. If not, how would you approach this problem? The puzzle pieces should be as close to a real jigsaw piece shape as possible and the system must be dynamic so that the user can use their own photos or download photos. thanks!

• Set ListBoxItem.IsSelected when child TextBox is Focused

  - by jpsstavares

  Hi, I have a typical MVVM scenario: I have a ListBox that is binded to a List of StepsViewModels. I define a DataTemplate so that StepViewModels are rendered as StepViews. The StepView UserControl have a set of labels and TextBoxs. What I want to do is to select the ListBoxItem that is wrapping the StepView when a textBox is focused. I've tried to create a style for my TextBoxs with the following trigger: <Trigger Property="IsFocused" Value="true"> <Setter TargetName="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}" Property="IsSelected" Value="True"/> </Trigger> But I get an error telling me that TextBoxs don't have an IsSelected property. I now that but the Target is a ListBoxItem. How can I make it work?

• Fitting maximum amount of shapes on a surface

  - by Fuu

  In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, made out of polygons and/or curved lines, and target is another polygon of given dimensions. I assume many of the current CAM suites implement this, but having no experience using them or of their internals, what kind of computational algorithm is used to find the most efficient use of space? Can someone point me to a book or other reference that discusses this subject?

• Does JavaScript have an equivalent to Perl's DESTROY method?

  - by Eric Strom

  Is there any method that is called or event that is dispatched right before an Element is cleaned up by the JavaScript garbage collector? In Perl I would write: package MyObj; sub new {bless {}} sub DESTROY {print "cleaning up @_\n"} and then later: { my $obj = MyObj->new; # do something with obj } # scope ends, and assuming there are no external references to $obj, # the DESTROY method will be called before the object's memory is freed My target platform is Firefox (and I have no need to support other browsers), so if there is only a Firefox specific way of doing this, that is fine. And a little background: I am writing the Perl module XUL::Gui which serves as a bridge between Perl and Firefox, and I am currently working on plugging a few memory leaks related to DOM Elements sticking around forever, even after they are gone and no more references remain on the Perl side. So I am looking for ways to either figure out when JavaScript Elements will be destroyed, or a way to force JavaScript to cleanup an object.

• How to call/use a value converter inverted

  - by Soko

  Is it possible to use a converter the "wrong" way around? In other words: can I swap source and target? Here's an example: I created a simple IValueConverter called NullableDecimalToStringConverter which converts an input if "" into null and a number into decimal. I use it to bind a TextBox in my WPF view to a decimal? property in my ViewModel. In another context I'd like to convert a NullableDecimal into a String in the same way... Is it possible to simply use the existing NullableDecimalToStringConverter inverted? One method is to use the parameter of the converter to tell the converter which way it should convert. But is there a .NET build in way to do such a thing? Another way would be to build a base class with both conversion methods and two separate converter which call the base class methods...

• Passing a variable to javascript via a link.

  - by Jon

  My website has a javascript variable (addselectedsubdivision) that loads a neighborhood name from a box on the left to a box on the right. I was hoping I could build a link and then us PHP to add the subdivision letter, neighborhood, and city so that when you click on the link it goes right to this page and loads the neighborhood name in the box on the right. However, I can't get the variable to pass to the new page. Any suggestions?

• Show surrounding words when searching for a specific word in a text file (Ruby)

  - by Ezra

  Hi, I'm very new to ruby. I'm trying to search for any instance of a word in a text file (not the problem). Then when the word is discovered, it would show the surrounding text (maybe 3-4 words before and after the target word, instead of the whole line), output to a list of instances and continue searching. Example "The quick brown fox jumped over the lazy dog." Search word = "jumped" Output = "...brown fox jumped over the..." Any help is appreciated. Thanks! Ezra def word_exists_in_file f = File.open("test.txt") f.each do line print line if line.match /someword/ return true end end false end

• Under *nix, how can I find a string within a file within a directory ?

  - by roberto

  Hi all. I'm using ubuntu linux, and I use bash from with a terminal emulator every day for many tasks. I would like to know how to find a string or a substring within a file that is within a particular directory. If I was knew the file which contained my target substring, I would just cat the file and pipe it through grep, thus: cat file | grep mysubstring But in this case, the pesky substring could be anywhere within a known directory. How do I hunt down my substring ?

• "Cannot use fixed local inside lambda expression"

  - by JulianR

  I have an XNA 3.0 project that compiled just fine in VS2008, but that gives compile errors in VS2010 (with XNA 4.0 CTP). The error: Cannot use fixed local 'depthPtr' inside an anonymous method, lambda expression, or query expression depthPtr is a fixed float* into an array, that is used inside a Parallel.For lambda expression from System.Threading. As I said, this compiled and ran just fine on VS2008, but it does not on VS2010, even when targeting .NET 3.5. Has this changed in .NET 4.0, and even so, shouldn't it still compile when I choose .NET 3.5 as the target framework? Searching for the term "Cannot use fixed local" yields exactly one (useless) result, both in Google and Bing. If this has changed, what is the reason for this? I can imagine capturing a fixed pointer-type in a closure could get a bit weird, is that why? So I'm guessing this is bad practice? And before anyone asks: no, the use of pointers is not absolutely critical here. I would still like to know though :)

• Open page in Joomla

  - by dutt

  I'm using Jumi to echo php code and then showing that in a Joomla Article, and everythings working fine. Now I want to do this: The output is basically a list from a database like this: Name Price Type A 1 T1 B 2 T2 In this list I want to include links to only show items of the same type, so "T1" would like to a page only showing things of type T1. So I thought I would do this by making a new page that takes a type and then get all the items of that type from the database. Without Joomla this wouldv'e been a piece of cake, with Joomla I'm not quite sure where to begin. How should the a href=... tags in the html code printed by my php script look? Is my basic structure still correct, and if so, how do I make Joomla open the new page in the normal frame and not replace the whole Joomla page. some kind of target-frame attribute?

• How do I make a new div with a specific Id + n?

  - by Noor

  I've got a button and when it's pushed this code launches: var nrDivs = "1" var neuDiv = document.createElement("div"); neuDiv.setAttribute("Id","theDiv" + nrDivs); neuDiv.innerHTML = "Text"; $('#allDivs').append(neuDiv); newfeed.draw(neuDiv); I know that right now the script creates a new div with the ID: theDiv1. What I'm trying to do is when I click the button a second time, it creates a div with the ID: theDiv2. Each time the user presses the button there should be a new div drawn and I'm trying to target that new div and insert dynamic text. Thanks, Noor
