• Integrate QT and OpenCV in Visual Studio

  - by user2891190

  Sorry If you feel that this is an already asked question. But I googled for more than 2 days any tried lots of solution which given through stackoverflow and referred lots of tutorials. But I couldn't get a proper idea. I am already working in a project which use c++(visual studio) with opencv which I am developing as my university project. I have developing this for last 2 months. But now I want to add a better UI.(Previously I considered only on the functionality) So I decided to move into QT. I'm new to QT. So I did some google search. I know that I can do this with the QT creator. But I want to do this in visual studio as the functionality of my project is bit complex. What I already know is I have to build opencv with Qt using cmake. I followed few tutorials. But most of the tutorials use mingw and QT creator. http://www.anlak.com/build-debug-opencv-vs2010/ Accoring to above tutorial I generated a visual studio project using cmake. But when I tried to open that solution file my visual studio becomes not-responding. I can't figure out the reason. I tried two days and I couldn't find a proper tutorial which describes integration of QT and opencv in visual studio. So can someone give me the instruction to integrate QT and Opencv in visual studio.

• What is the proper syntax for getting a Makefile to print the output directory of one of its output zip files?

  - by 9exceptionThrower9

  I'm trying to edit an Android Makefile in the hopes of getting it to print out the directory (path) location of one the ZIP files it creates. Ideally, since the build process is long and does many things, I would like for it print out the pathway to the ZIP file to a text file in a different directory I can access later: Pseudo-code idea: # print the desired pathway to output file print(getDirectoryOf(variable-name.zip)) > ~/Desktop/location_of_file.txt The Makefile snippet where I would like to insert this new bit of code is shown below. I am interested in finding the directory of $(name).zip (that is specific file I want to locate): # ----------------------------------------------------------------- # A zip of the directories that map to the target filesystem. # This zip can be used to create an OTA package or filesystem image # as a post-build step. # name := $(TARGET_PRODUCT) ifeq ($(TARGET_BUILD_TYPE),debug) name := $(name)_debug endif name := $(name)-target_files-$(FILE_NAME_TAG) intermediates := $(call intermediates-dir-for,PACKAGING,target_files) BUILT_TARGET_FILES_PACKAGE := $(intermediates)/$(name).zip $(BUILT_TARGET_FILES_PACKAGE): intermediates := $(intermediates) $(BUILT_TARGET_FILES_PACKAGE): \ zip_root := $(intermediates)/$(name) # $(1): Directory to copy # $(2): Location to copy it to # The "ls -A" is to prevent "acp s/* d" from failing if s is empty. define package_files-copy-root if [ -d "$(strip $(1))" -a "$$(ls -A $(1))" ]; then \ mkdir -p $(2) && \ $(ACP) -rd $(strip $(1))/* $(2); \ fi endef

• How to manage feeds with subclassed object in Django 1.2?

  - by Matteo

  Hi, I'm trying to generate a feed rss from a model like this one, selecting all the Entry objects: from django.db import models from django.contrib.sites.models import Site from django.contrib.auth.models import User from imagekit.models import ImageModel import datetime class Entry(ImageModel): date_pub = models.DateTimeField(default=datetime.datetime.now) author = models.ForeignKey(User) via = models.URLField(blank=True) comments_allowed = models.BooleanField(default=True) icon = models.ImageField(upload_to='icon/',blank=True) class IKOptions: spec_module = 'journal.icon_specs' cache_dir = 'icon/resized' image_field = 'icon' class Post(Entry): title = models.CharField(max_length=200) description = models.TextField() slug = models.SlugField(unique=True) def __unicode__(self): return self.title class Photo(Entry): alt = models.CharField(max_length=200) description = models.TextField(blank=True) original = models.ImageField(upload_to='photo/') class IKOptions: spec_module = 'journal.photo_specs' cache_dir = 'photo/resized' image_field = 'original' def __unicode__(self): return self.alt class Quote(Entry): blockquote = models.TextField() cite = models.TextField(blank=True) def __unicode__(self): return self.blockquote When I use the render_to_response in my views I simply call: def get_journal_entries(request): entries = Entry.objects.all().order_by('-date_pub') return render_to_response('journal/entries.html', {'entries':entries}) And then I use a conditional template to render the right snippets of html: {% extends "base.html" %} {% block main %} <hr> {% for entry in entries %} {% if entry.post %}[...]{% endif %}[...] But I cannot do the same with the Feed Framework in django 1.2... Any suggestion, please?

• Advanced All In One .NET Framework (should i go for a software factory ?)

  - by alfredo dobrekk

  Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration logging screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... At this point i have 3 options : Build from scratch on top of clr :( Find functionnalities among several open source framework and use them as a stack for infrastucture Find a "software factory" I know its lot but i really would like to use existing code to build upon so i can focus on business rules. What open source tools would u use to achieve these ?

• Prototyping Qt/C++ in Python

  - by tstenner

  I want to write a C++ application with Qt, but build a prototype first using Python and then gradually replace the Python code with C++. Is this the right approach, and what tools (bindings, binding generators, IDE) should I use? Ideally, everything should be available in the Ubuntu repositories so I wouldn't have to worry about incompatible or old versions and have everything set up with a simple aptitude install. Is there any comprehensive documentation about this process or do I have to learn every single component, and if yes, which ones? Right now I have multiple choices to make: Qt Creator, because of the nice auto completion and Qt integration. Eclipse, as it offers support for both C++ and Python. Eric (haven't used it yet) Vim PySide as it's working with CMake and Boost.Python, so theoretically it will make replacing python code easier. PyQt as it's more widely used (more support) and is available as a Debian package. Edit: As I will have to deploy the program to various computers, the C++-solution would require 1-5 files (the program and some library files if I'm linking it statically), using Python I'd have to build PyQt/PySide/SIP/whatever on every platform and explain how to install Python and everything else.

• Android - Adding external library to project

  - by mmontalbo

  Hi, I am having a lot of trouble adding the WEKA library to a project I am working on. I have followed several tutorials that explain how to do this including the Android Developers guide: http://developer.android.com/guide/appendix/faq/commontasks.html#addexternallibrary and several of the postings on SO. I have created a folder in my project with the weka.jar file, created a new library (adding the weka.jar file to the library) and included this library in my build path. I have also added the library under the "Order and Export" tab in the project properties. I have also tried importing the jar file so that the actual contents of the jar are extracted into a directory in my project. The end result of all of this is that my project is able to build correctly and without error, but when it comes time to run my code on the emulator I get the following exception: 04-10 22:52:21.051: ERROR/dalvikvm(582): Could not find class 'weka.classifiers.trees.J48', referenced from method edu.usc.student.composure.classifier.GaitClassifierImpl. with J48 being the class I reference in my code. Does anyone have any additional suggestions that I may have overlooked? Thanks!

• Do vs. Run vs. Execute vs. Perform verbs

  - by coffeeaddict

  Before anyone starts to go nuts and red flag this post saying this is "Subjective" which drives me absolutely nuts because everyone has their own intent why they are posting something others feel are subjective. Subjective is subjective to each person, how about that! So with that let me tell you a couple things so that this post does not get flagged by flag happy moderators: 1) There are community guidlines on specific keywords recommended by certain organizations or people (e.g. Microsoft, Lance Hunt, etc.) 2) I want to know what others are using the most and why. Why they feel this verb reads better than others 3) Books even talk about this verb issue (Uncle Bob, etc.), so it's not subjective Now to my actual question: a) What list of verbs are you using for method names? What's your personal or team standard? b) I debate whether to use Do vs. Run vs. Execute vs. Perform and am wondering if any of these are no longer recommended or some that people just don't really use and I should just scratch them. Basically any one of those verbs mean the same thing...to invoke some process (method call). This is outside of CRUDs. For example: ExecutePayPalWorkflow(); that could be also any one of these names instead: DoPayPalWorkflow(); RunPayPalWorkflow(); PerformPayPalWorkflow(); or does it not really matter...because any of those verbs pretty much are understandable as to "what" shows your intent by the other words that follow it "PayPalWorkflow" This discussion can go for any language. I just put the two main tags C# and Java here which is good enough for me to get some solid answers or experiences.

• Doxygen including methods twice doc files

  - by Maarek

  I'm having this issue where doxygen is adding the method twice in the documentation file. Is there a setting that stops auto-generation of documentation for methods within the .m file. For example in the documentation I'll see something like whats below where the first definition of + (Status *)registerUser is from the header XXXXXX.h file where the second is from XXXXXX.m. Header documentation : /** @brief Test Yada Yada @return <#(description)#> */ + (Status *)registerUser; Output: + (Status *) registerUser Test Yada Yada. Returns: <#(description)#> + (Status *) registerUser <#(brief description)#> <#(comprehensive description)#> registerUser Returns: <#(description)#> Definition at line 24 of file XXXXXX.m. Here are the build related configuration options. I've tried playing with them. EXTRACT_ALL with YES and NO... Hiding uncodumented Members and Classes. #--------------------------------------------------------------------------- # Build related configuration options #--------------------------------------------------------------------------- EXTRACT_ALL = NO EXTRACT_PRIVATE = NO EXTRACT_STATIC = NO EXTRACT_LOCAL_CLASSES = YES EXTRACT_LOCAL_METHODS = NO EXTRACT_ANON_NSPACES = NO HIDE_UNDOC_MEMBERS = YES HIDE_UNDOC_CLASSES = YES HIDE_FRIEND_COMPOUNDS = NO HIDE_IN_BODY_DOCS = NO INTERNAL_DOCS = NO CASE_SENSE_NAMES = NO HIDE_SCOPE_NAMES = NO SHOW_INCLUDE_FILES = YES FORCE_LOCAL_INCLUDES = NO INLINE_INFO = YES SORT_MEMBER_DOCS = YES SORT_BRIEF_DOCS = NO SORT_MEMBERS_CTORS_1ST = NO SORT_GROUP_NAMES = NO SORT_BY_SCOPE_NAME = NO

• Drupal 6 Validation for Form Callback Function

  - by Wade

  I have a simple form with a select menu on the node display page. Is there an easy way to validate the form in my callback function? By validation I don't mean anything advanced, just to check that the values actually existed in the form array. For example, without ajax, if my select menu has 3 items and I add a 4th item and try to submit the form, drupal will give an error saying something similar to "an illegal choice was made, please contact the admin." With ajax this 4th item you created would get saved into the database. So do I have to write validation like if ($select_item > 0 && $select_item <= 3) { //insert into db } Or is there an easier way that will check that the item actually existed in the form array? I'm hoping there is since without ajax, drupal will not submit the form if it was manipulated. Thanks. EDIT: So I basically need this in my callback function? $form_state = array('storage' => NULL, 'submitted' => FALSE); $form_build_id = $_POST['form_build_id']; $form = form_get_cache($form_build_id, $form_state); $args = $form['#parameters']; $form_id = array_shift($args); $form_state['post'] = $form['#post'] = $_POST; $form['#programmed'] = $form['#redirect'] = FALSE; drupal_process_form($form_id, $form, $form_state); To get $_POST['form_build_id'], I sent it as a data param, is that right? Where I use form_get_cache, looks like there is no data. Kind of lost now.

Please try again later.** This has happened repeatedly for two days since I started trying to implement it. Not a very helpful error message. Any idea what might cause it or how to narrow down the problem?

• Rails partial gets double escaped when using link_to_function

  - by dombesz

  Hi, I have the following code. def add_resume_link(name, form) link_to_function name do |page| html = form.fields_for :resumes, @general_resume.resumes.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial => 'resume_form', :locals=>{:form=>form_parent} end page << "$('resumes').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, id) });" end end And on the resume_form i have somewhere: =add_skill_link("Add Skill", form, "resume_#{id}_skills") and the function looks like: def add_skill_link(name, form, id) link_to_function name do |page| html = form.fields_for :skill_items, @general_resume.skill_items.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial=>'skill_form', :locals=>{:form=>form_parent, :parent=>id} end page << "$('#{id}').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, new Date().getTime()) });" end end So basically i have a javascript code which dinamically adds a piece of html (add_resume) and contains another javascript code which dinamically adds a select box to the page. My problem is that the add_skill_link works fine if i use from the server side, i mean rendering from server side. And gets double escaped when using within the upper described way. I tried to remove the escape_javascript from the add_skill_link bit still not good. Any ideas?

• Devise password reset issue (new_user?)

  - by rabid_zombie

  When a user's email is inputted into the forgot password form and submitted, I am receiving an error saying login can't be blank. I looked around devise.en.yml for this error message, but can't seem to find it anywhere. Here is my views/devise/passwords/new.html.haml: %div.registration_page %h2 Forgot your password? = form_for(resource, :as => resource_name, :url => user_password_path, :html => { :method => :post, :id => 'forgot_pw_form', :class => 'forgot_pw' }) do |f| %div = f.email_field :email, :placeholder => 'Email', :autofocus => true, :autocomplete => 'off' %div.email_error.error %input.btn.btn-success{:type => 'submit', :value => 'Send Instructions'} = render "devise/shared/links" The form is posting to users/password like it should, but I noticed that my forgot password form attaches class = 'new_user'. Here is what my form displays: <form accept-charset='UTF-8' action='/users/password' class='new_user' id='forgot_pw_form' method='post' novalidate='novalidate'></form> My routes for devise (I have custom sessions and registrations controllers): devise_for :users, :controllers => {:sessions => 'sessions', :registrations => 'registrations'} How can I setup devise's forgot password functionality? Why am I receiving this error message and why is that class being added there? I've tried: Adding my own passwords controller and adding new routes for my custom controller. Same error Adding my own class and id to the form. This successfully changes the id and class of the form, but reverts back to class and id of new_user Thanks.

• Firefox handles xxx.submit(), Safari doesn't ... what can be done?

  - by Prairiedogg

  I'm trying to make a pull down menu post a form when the user selects (releases the mouse) on one of the options from the menu. This code works fine in FF but Safari, for some reason, doesn't submit the form. I re-wrote the code using jquery to see if jquery's .submit() implementation handled the browser quirks better. Same result, works in FF doesn't work in safari. The following snippets are from the same page, which has some django template language mixed in. Here's the vanilla js attempt: function formSubmit(lang) { if (lang != '{{ LANGUAGE_CODE }}') { document.getElementById("setlang_form").submit(); } } Here's the jquery attempt: $(document).ready(function() { $('#lang_submit').hide() $('#setlang_form option').mouseup(function () { if ($(this).attr('value') != '{{ LANGUAGE_CODE }}') { $('#setlang_form').submit() } }); }); and here's the form: <form id="setlang_form" method="post" action="{% url django.views.i18n.set_language %}"> <fieldset> <select name="language"> {% for lang in interface_languages %} <option value="{{ lang.code }}" onmouseup="formSubmit('{{ lang.name }}')" {% ifequal lang.code LANGUAGE_CODE %}selected="selected"{% endifequal %}>{{ lang.name }}</option> {% endfor %} </select> </fieldset> </form> My question is, how can I get this working in Safari?

• Paperclip: Stay put on edit

  - by EricR

  When a user edits something in my application, they're forced to re-upload their image via paperclip even if they aren't changing it. Failing to do so will cause an error, since I validate_presence_of :image. This is quite annoying. How can I make it so Paperclip won't update its attributes if a user simply doesn't supply a new image on an edit? The photo controller is fresh out of Rails' scaffold generator. The rest of the source code is provided below. models/accommodation.rb class Accommodation < ActiveRecord::Base attr_accessible :photo validates_presence_of :photo has_one :photo has_many :notifications belongs_to :user accepts_nested_attributes_for :photo, :allow_destroy => true end controllers/accommodation_controller.rb class AccommodationsController < ApplicationController def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def new @accommodation = current_user.accommodations.build @accommodation.build_photo end def create @accommodation = current_user.accommodations.build(params[:accommodation]) if @accommodation.save flash[:notice] = "Successfully created your accommodation." redirect_to @accommodation else @accommodation.build_photo render :new end end def edit @accommodation = Accommodation.find(params[:id]) @accommodation.build_photo rescue ActiveRecord::RecordNotFound flash[:error] = "Accommodation not found." redirect_to :home end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." redirect_to @accommodation else @accommodation.build_photo render :edit end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end end models/photo.rb class Photo < ActiveRecord::Base attr_accessible :image, :primary belongs_to :accommodation has_attached_file :image, :styles => { :thumb=> "100x100#", :small => "150x150>" } end

• What's the best way to send user-inputted text via AJAX to Google App Engine?

  - by Cuga

  I'm developing in Google App Engine (python sdk) and I want to use jQuery to send an Ajax request to store an answer to a question. What is the best way to send this data to the server? Currently I have: function storeItem(question_id) { var answerInputControl = ".input_answer_"+question_id; var answer_text = $(answerInputControl).text(); $.ajax({ type: "POST", url: "store_answer.html", data: "question="+question_id, success: function(responseText){ alert("Retrieved: " + responseText); } }); } This takes a question Id and provides it to the server via the query string. But on the server-side, I'm unable to access the content of the answer control which I want to store. Without Ajax, I'm able to perform this operation with the following: class StoreAnswers(webapp.RequestHandler): def post(self): question_id = self.request.get("question_id") answer_text = self.request.get("input_answer" + question_id) But when doing this call through Ajax, my answer_text is empty. Do I need to send the contents of this control as part of the data with the Ajax request? Do I add the control itself to the query string? Its contents? Does it matter that the content might be a few hundred characters long? Is this the most-recommended practice? If sending it as a query string, what's the best way to escape the content so that a malicious user doesn't harm the system?

• m2e lifecycle-mapping not found

  - by TraderJoeChicago

  I am trying to use the solution described here to solve the annoying "Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:build-helper-maven-plugin:1.7:add-source (execution: default, phase: generate-sources)" when I place the following plugin on my pom.xml: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <executions> <execution> <phase>generate-sources</phase> <goals><goal>add-source</goal></goals> <configuration> <sources> <source>src/bootstrap/java</source> </sources> </configuration> </execution> </executions> </plugin> But when I run mvn clean install I get this: Reason: POM 'org.eclipse.m2e:lifecycle-mapping' not found in repository: Unable to download the artifact from any repository Does anyone have a clue on how to make m2e and maven happy?

• Methods to see result fo a code change faster

  - by Can't Tell

  This question came to me when developing using Eclipse. I use JBoss Application Server and use hot code replacement. But this option requires that the 'build automatically' option to be enabled. This makes Eclipse build the workspace automatically (periodically or when a file is saved?) and for a large code base this takes too much time and processing which makes the machine freeze for a while. Also sometimes an error message is shown saying that hot code replacement failed. The question that I have is: is there a better way to see the result of a code change? Currently I have the following two suggestions: Have unit tests - this will allow to run a single test and see the result of a code change. ( But for a JavaEE application that uses EJBs is it easy to setup unit tests?) Use OSGi - which allows to add jars to the running system without bringing down the JVM. Any ideas on above suggestions or any other suggestion or a framework that allows to do this is welcome.

• Why can’t PHP script write a file on server 2008 via command line or task scheduler?

  - by rg89

  I created a question on serverfault.com, and it was recommended that I ask here. http://serverfault.com/questions/140669/why-cant-php-script-write-a-file-on-server-2008-via-command-line-or-task-schedul I have a PHP script. It runs well when I use a browser. It writes an XML file in the same directory. The script takes ~60 seconds to run, and the resulting XML file is ~16 MB. I am running PHP 5.2.13 via FastCGI on Windows Server Web edition SP1 64 bit. The code pulls inventory from SQL server, runs a loop to build an XML file for a third party. I created a task in task scheduler to run c:\php5\php.exe "D:\inetpub\tools\build.php" The task scheduler shows a time lapse of about a minute, which is how long the script takes to run in a browser. No error returned, but no file created. Each time I make a change to the scheduled task properties, a user password box comes up and I enter the administrator account password. If I run this same path and argument at a command line it does not error and does not create the file. When I right click run command prompt as an administrator, the file is still not created. I get my echo statement "file published" that is after the file creation and no error is returned. I am doing a simple fopen fwrite fclose to save the contents of a php variable to a .xml file, and the file only gets created when the script is run through the browser. Here's what happens after the xml-building loop: $feedContent .= "</feed"; sqlsrv_close( $conn ); echo "<p>feed built</p>"; $feedFile = "feed.xml"; $handler = fopen($feedFile, 'w'); fwrite( $handler, $feedContent ); fclose( $handler ); echo "<p>file published</p>"; Thanks
