  • C++ trouble with pointers to objects

    - by Zibd
    I have a class with a vector of pointers to objects. I've introduced some elements on this vector, and on my main file I've managed to print them and add others with no problems. Now I'm trying to remove an element from that vector and check to see if it's not NULL but it is not working. I'm filling it with on class Test: Other *a = new Other(1,1); Other *b = new Other(2,2); Other *c = new Other(3,3); v->push_back(a); v->push_back(b); v->push_back(c); And on my main file I have: Test t; (...) Other *pointer = t.vect->at(0); delete t.vect->at(0); t.vect->erase(t.vect->begin()); if (pointer == NULL) { cout << "Nothing here.."; } // Never enters here..

  • Element not found blocks execution in Selenium

    - by Mariano
    In my test, I try to verify if certain text exists (after an action) using find_element_by_xpath. If I use the right expression and my test pass, the routine ends correctly in no time. However if I try a wrong text (meaning that the test will fail) it hangs forever and I have to kill the script otherwise it does not end. Here is my test (the expression Thx user, client or password you entered is incorrect does not exist in the system, no matter what the user does): # -*- coding: utf-8 -*- import gettext import unittest from selenium import webdriver class TestWrongLogin(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.get("http://10.23.1.104:8888/") # let's check the language try: self.lang = self.driver.execute_script("return navigator.language;") self.lang = self.lang("-")[0] except: self.lang = "en" language = gettext.translation('app', '/app/locale', [self.lang], fallback=True) language.install() self._ = gettext.gettext def tearDown(self): self.driver.quit() def test_wrong_client(self): # test wrong client inputElement = self.driver.find_element_by_name("login") inputElement.send_keys("root") inputElement = self.driver.find_element_by_name("client") inputElement.send_keys("Unleash") inputElement = self.driver.find_element_by_name("password") inputElement.send_keys("qwerty") self.driver.find_element_by_name("form.submitted").click() # wait for the db answer self.driver.implicitly_wait(10) ret = self.driver.find_element_by_xpath( "//*[contains(.,'{0}')]".\ format(self._(u"Thx user, client or password you entered is incorrect"))) self.assertTrue(isinstance(ret, webdriver.remote.webelement.WebElement)) if __name__ == '__main__': unittest.main() Why does it do that and how can I prevent it?

  • Programmatically change the icon of the executable

    - by Dennis Delimarsky
    I am developing an application called WeatherBar. Its main functionality is based on its interaction with the Windows 7 taskbar — it changes the icon depending on the weather conditions in a specific location. The icons I am using in the application are all stored in a compiled native resource file (.res) — I am using it instead of the embedded resource manifest for icons only. By default, I modify the Icon property of the main form to change the icons accordingly and it works fine, as long as the icon is not pinned to the taskbar. When it gets pinned, the icon in the taskbar automatically switches to the default one for the executable (with index 0 in the resource file). After doing a little bit of research, I figured that a way to change the icon would be changing the shortcut icon (as all pinned applications are actually shortcuts stored in the user folder). But it didn't work. I assume that I need to change the icon for the executable, and therefore use UpdateResource, but I am not entirely sure about this. My executable is not digitally signed, so it shouldn't be an issue modifying it. What would be the way to solve this issue?

  • Changing type of object in a conditional

    - by David Doria
    I'm having a bit of trouble with dynamic_casting. I need to determine at runtime the type of an object. Here is a demo: include include class PersonClass { public: std::string Name; virtual void test(){}; //it is annoying that this has to be here... }; class LawyerClass : public PersonClass { public: void GoToCourt(){}; }; class DoctorClass : public PersonClass { public: void GoToSurgery(){}; }; int main(int argc, char *argv[]) { PersonClass* person = new PersonClass; if(true) { person = dynamic_cast(person); } else { person = dynamic_cast(person); } person-GoToCourt(); return 0; } I would like to do the above. The only legal way I found to do it is to define all of the objects before hand: PersonClass* person = new PersonClass; LawyerClass* lawyer; DoctorClass* doctor; if(true) { lawyer = dynamic_cast(person); } else { doctor = dynamic_cast(person); } if(true) { lawyer-GoToCourt(); } The main problem with this (besides having to define a bunch of objects that won't be use) is that I have to change the name of the 'person' variable. Is there a better way? (I am not allowed to change any of the classes (Person, Lawyer, or Doctor) because they are part of a library that people who will use my code have and won't want to change). Thanks, Dave

  • How to Implement Backbone Java Logic Code into Android

    - by lord_sneed
    I wrote a program to work from the console in Eclipse and the terminal window in Linux. I am now transforming it into an Android app and I have the basic functionality of the Android UI done up until the point where it needs to use the logic from the Java file of the program I wrote. All of my inputs from the Java file are currently from the keyboard (from Scanners). My question is: how do I transform this to get it work with the user interaction of the app? The only input would be from the built in NumberPicker. Should I copy and paste the code from the Java program to the activity file in the onCreate method and change all of the input methods (Scanners) to work with the Android input? Or do I create variables in the activity file and pass them to the Java program (in the separate class)? (If so, how would I do that? the Java file starts from the main method: public static void main(String[] args) {) Also, will the print statements I have, System.out.println(...);, translate directly into the Android UI and print on the screen or do I have to modify those?

  • A public struct inside a class

    - by Koning Baard
    I am new to C++, and let's say I have two classes: Creature and Human: /* creature.h */ class Creature { private: public: struct emotion { /* All emotions are percentages */ char joy; char trust; char fear; char surprise; char sadness; char disgust; char anger; char anticipation; char love; }; }; /* human.h */ class Human : Creature { }; And I have this in my main function in main.cpp: Human foo; My question is: how can I set foo's emotions? I tried this: foo->emotion.fear = 5; But GCC gives me this compile error: error: base operand of '-' has non-pointer type 'Human' This: foo.emotion.fear = 5; Gives: error: 'struct Creature::emotion' is inaccessible error: within this context error: invalid use of 'struct Creature::emotion' Can anyone help me? Thanks P.S. No I did not forget the #includes

  • Can't get my Jscrollpane working in my Jtextarea

    - by Bobski
    I've looked around quite a lot on google and followed several examples however I can't seem to get my JScrollPane working on a textarea in a JPanel. import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.lang.*; import javax.swing.event.*; class main { public static void main(String Args[]) { frame f1 = new frame(); } } class frame extends JFrame { JButton B = new JButton("B"); JButton button = new JButton("A"); JTextArea E = new JTextArea("some lines", 10, 20); JScrollPane scrollBar = new JScrollPane(E); JPanel grid = new JPanel (); frame() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(500,800); setTitle("Mobile Phone App"); setLocationRelativeTo(null); E.setLineWrap(true); E.setEditable(false); grid.add(button); button.addActionListener(new action()); grid.add(B); B.addActionListener(new action()); //grid.add(E); grid.getContentPane().add(scrollBar); add(grid); setVisible(true); } class action implements ActionListener { public void actionPerformed(ActionEvent e) { String V = E.getText(); if(e.getSource() == button) { E.setText(V + "A is pressed"); } if(e.getSource() == B) { E.setText(V + "B is pressed"); } } } } Would be great if someone can see where I am going wrong. I added JscrollPane in which I added the text area "e" in it.

  • How do I avoid killing the native controls on a html5-video when i've started it programmaticly?

    - by Nils
    OK, so the deal is I've started making a little videoplayer, that works by clicking a div with an image, expanding the div and the image, and then exchanges the image with a html5-videotag. the code is as below. (It's very early on, so i know theres a lot that need improving, as in not using javascript to set styles and so on, but nevertheless, any insigts and tips are welcome, besides the answer to the main question) /*Begin Expander*/ var $videoplayer = $('<video width="640" height="360" preload="none" controls="" tabindex="0" style="position: relative;"><source type="video/mp4" src="/restalive/movies/big_buck_bunny.mp4"></source><source type="video/ogg" src="/restalive/movies/big_buck_bunny.ogv"></source></video>').appendTo('body'); $videoplayer.hide(); $(".ExpandVideo").each(function(i){ var $trigger = $(this); var $image = $trigger.find("img"); $image.css({ "width" : "100%" ,"height" : "auto" }) $trigger.css({ "display" : "block" ,"overflow" : "hidden" ,"width" : "200px" ,"float" : "left" }); $trigger.bind("click", function(e){ $trigger.animate({"width" : "640px"}, "fast", function(){ $image.replaceWith($videoplayer); $videoplayer.show(); $videoplayer.attr("id", "video" + i); var video = document.getElementById("video" + i); video.play(); }) }) }); However, the main problem is that when i've fired of the video like this (video.play()), the native controls stop working, i can no longer pause the video, even though the controls are there, and clickable, the video just starts playing immidiatley again when i trie to pause it. Which is a shame, because i want to use the native controls for simplicity.

  • pointer to a pointer in a linked list

    - by user1596497
    I'm trying to set a linked list head through pointer to a pointer.

  • I need help solving a rather weird error in a WCF service.

    - by Moulde
    Hi.. I have a solution that contains three projects. A main project with my MVC app, a silverlight application and a (silverlight enabled) WCF service project. In my silverlight project i have made a Service Reference to my WCF service. And i pretty much got that working. In my WCF service i have a method that returns an Book object, which got some random fields like title, date etc. In the book class, i have a ICollection field that contains a list of events. The book class is generated using entity framework 4.0, and Lazy Loading is enabled. If i in my getBook(int id) method return a book with the events field not initialized, it works as a charm. But if i initialize the field, i'm getting this error. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error. I have a few ideas why that is happening, and while writing this i just got another one. The wcf service somehow threw away the reference to the event class. That would be very weird since i have a reference between my main mvc app (with the models) and my WCF service. Since i have enabled lazy loading in EF 4.0, i suspect that it may be the thing generating the error. But i'm not sure why that would be, because i'm not in any way accessing that field. I could understand that i may not be able to access the events field after i recive the object in my silverlight application since the connection between the book object and the entity framework is like broken. Did i mention that Lazy Loading is enabled on my EF instance? And there is no inner exception in the thrown exception. Thanks in advance. Malte Baden Hansen

  • Magento - use an alternate "price.phtml" (in addition to the existing one)

    - by sdek
    I am looking for a way to have an alternate template/catalog/product/price.phml used in one specific location, and to continue using the existing price.phtml file in all other locations. To explain further, I need to display the regular price, and then another special price right below it - but only on the product page (for the main product being displayed). This special price is not a price that can be calculated by the catalog price rules, so I wrote my own module to do the calculation. So, everywhere that I am displaying prices I want to display with the regular ol' template/catalog/product/price.phtml file... but for the product page (the main product - not the related, upsells, etc) I want to use my own custom template/catalog/product/price-custom.phtml template file. Can anybody help? Normally I just look in the layout xml files (for example catalog.xml) to find these types of things, but price.phtml is kinda special - it isn't that simple. And for the life of me I can't figure out if there is an easy way to swap it out conditionally on the page being viewed. I am aware that I can just update price.phtml to always print out this extra price, and then use css to hide the price everywhere, but I would rather not do that if possible. (Also you may want to know that I only have simple products.)

  • Where should my "filtering" logic reside with Linq-2-SQL and ASP.NET-MVC in View or Controller?

    - by Nate Bross
    I have a main Table, with several "child" tables. TableA and TableAChild1 and TableAChild2. I have a view which shows the information in TableA, and then has two columns of all items in TableAChild1 and TableAChild2 respectivly, they are rendered with Partial views. Both child tables have a bit field for VisibleToAll, and depending on user role, I'd like to either display all related rows, or related rows where VisibleToAll = true. This code, feels like it should be in the controller, but I'm not sure how it would look, because as it stands, the controller (limmited version) looks like this: return View("TableADetailView", repos.GetTableA(id)); Would something like this be even work, and would it be bad what if my DataContext gets submitted, would that delete all the rows that have VisibleToAll == false? var tblA = repos.GetTableA(id); tblA.TableAChild1 = tblA.TableAChild1.Where(tmp => tmp.VisibleToAll == true); tblA.TableAChild2 = tblA.TableAChild2.Where(tmp => tmp.VisibleToAll == true); return View("TableADetailView", tblA); It would also be simple to add that logic to the RendarPartial call from the main view: <% Html.RenderPartial("TableAChild1", Model.TableAChild1.Where(tmp => tmp.VisibleToAll == true); %>

  • Small Open source and free java applications

    - by user1089770
    I am a Perl Developer who has just stepped into the Java world and I want to be very proficient in Java EE development. However, I have found that, being a Perl guy, I have very high MTI(Mother Tongue Influence). Indians will know what MTI is. For others, it can be defined as an influence of your "main" language whenever you "speak" your new language. In other words, our mind converts/translates what we want to "say" in the new language based on the "main" language, which can be quite absurd or meaning less in the "new" language. Coming back to the point, as a result of this MTI, many lines of my code has this Perl influence and it is absurd and useless for production. Hence, I'd like to see or better do some research on existing small to medium open source java applications, so that I will know how I can "speak" in the native way of the "new" language. Some examples in PHP will be : WordPress, Zend etc. So I'd really appreciate if you guys could suggest any such apps. Apps that have a great commercial value are highly preferred

  • check if two subsets of integers are equal using equals method

    - by MAS
    I have this java method in class called IntArray. The class has methods to add integers to a set or remove integers from a set,check size of a set, and check if 2 sets are equal. the 2 sets are created using 2 different objects of type IntArray in main, lets say object A and B. equals method supposed to check if two sets of integers are equal. for example set A = {1,2,3} and B = {1,2,3,4}. The method still return true even though one set is a subset of the other set. What exactly I am doing wrong? Thanks. //part of the code in main IntArray A = new IntArray(); IntArray B = new IntArray(); if(A.equals(B)) System.out.println("A and B are equal"); //equals method in IntArray class public boolean equals(Object b) { if (b instanceof IntArray) { IntArray A = (IntArray) b; for (int i = 0; i < data.length; i++) if (countOccurrences(data[i]) != A.countOccurrences(data[i])) return false; return true; } else return false; }

  • Best practice- How to team-split a django project while still allowing code reusal

    - by Infinity
    I know this sounds kind of vague, but please let me explain- I'm starting work on a brand new project, it will have two main components: "ACME PRODUCT" (think Gmail, Meebo, etc), and "THE SITE" (help, information, marketing stuff, promotional landing pages, etc lots of marketing-induced cruft). So basically the url /acme/* will load stuff in the uber cool ajaxy application, and every other URI will load stuff in the other site. Problem: "THE SITE" component is out of my hands, and will be handled by a consultants team that will work closely with marketing, And I and my team will work solely on the ACME PRODUCT. Question: How to set up the django project in such a way that we can have: Seperate releases. (They can push new marketing pages and functionality without having to worry about the state of our code. Maybe even separate Subversion "projects") Minimize impact (on our product) of whatever flying-unicorns-hocus-pocus the other team codes into the site. Still allow some code reusal. My main concern is that the ACME product needs to be rock solid, and therefore needs to be somewhat isolated of whatever mistakes/code bloopers the consultants make in their marketing side of the site. How have you handled this? Any ideas? Thanks!

  • Flex 3 (Action Script): How to access a function from a loaded swf-file ?

    - by Trantec
    Hi, i load in ActionScript a swf file. So far no Problem, but I didn't found a way to access one of it's functions, the best thing would be if I could access the main function in the mxml part of the swf. Here is the code of the main-mxml file that belongs to the swf that should load and access another swf: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="basket();"> <mx:Script> <![CDATA[ import mx.controls.SWFLoader; private function basket(): void { var swfLoader: SWFLoader = new SWFLoader(); swfLoader.addEventListener( Event.COMPLETE, handleSWFLoaded ); try { swfLoader.load( "../../data/InternalSWF.swf" ); } catch (error: Error) { trace( "Couldn't load file !" ); } } private function handleSWFLoaded( event: Event ): void { var swfApp:* = event.target.content; // This both ways don't work... //if (swfApp.hasOwnProperty("initApp")) { // var initApp:Function = (swfApp["initApp"] as Function); // initApp(); //} // swfApp.initApp(); } ]]> </mx:Script> <mx:Text id="output" width="100%" textAlign="center" /> </mx:Application> The if-Statement "if (swfApp.hasOwnProperty("initApp")) {" is never true and the call "swfApp.initApp()" says that this function does not exist. In the original version I added event listeners for HTTPStatusEvent.HTTP_STATUS, IOErrorEvent.IO_ERROR and SecurityErrorEvent.SECURITY_ERROR. But except for HTTP_STATUS = 0 none of them are called. Is the whole idea of how i try to do this wrong ?

Where can I add this element to get the desired effect?

  • Proper structure for dependency injection (using Guice)

    - by David B.
    I would like some suggestions and feedback on the best way to structure dependency injection for a system with the structure described below. I'm using Guice and thus would prefer solutions centered around it's annotation-based declarations, not XML-heavy Spring-style configuration. Consider a set of similar objects, Ball, Box, and Tube, each dependent on a Logger, supplied via the constructor. (This might not be important, but all four classes happen to be singletons --- of the application, not Gang-of-Four, variety.) A ToyChest class is responsible for creating and managing the three shape objects. ToyChest itself is not dependent on Logger, aside from creating the shape objects which are. The ToyChest class is instantiated as an application singleton in a Main class. I'm confused about the best way to construct the shapes in ToyChest. I either (1) need access to a Guice Injector instance already attached to a Module binding Logger to an implementation or (2) need to create a new Injector attached to the right Module. (1) is accomplished by adding an @Inject Injector injectorfield to ToyChest, but this feels weird because ToyChest doesn't actually have any direct dependencies --- only those of the children it instantiates. For (2), I'm not sure how to pass in the appropriate Module. Am I on the right track? Is there a better way to structure this? The answers to this question mention passing in a Provider instead of using the Injector directly, but I'm not sure how that is supposed to work. EDIT: Perhaps a more simple question is: when using Guice, where is the proper place to construct the shapes objects? ToyChest will do some configuration with them, but I suppose they could be constructed elsewhere. ToyChest (as the container managing them), and not Main, just seems to me like the appropriate place to construct them.

  • Obtaining command line arguments in a QT application

    - by morpheous
    The following snippet is from a little app I wrote using the QT framework. The idea is that the app can be run in batch mode (i.e. called by a script) or can be run interactively. It is important therefore, that I am able to parse command line arguments in order to know which mode in which to run etc. [Edit] I am debugging using QTCreator 1.3.1 on Ubuntu Karmic. The arguments are passed in the normal way (i.e. by adding them via the 'Project' settings in the QTCreator IDE). When I run the app, it appears that the arguments are not being passed to the application. The code below, is a snippet of my main() function. int main(int argc, char *argv[]) { //Q_INIT_RESOURCE(application); try { QApplication the_app(argc, argv); //trying to get the arguments into a list QStringList cmdline_args = QCoreApplication::arguments(); // Code continues ... } catch (const MyCustomException &e) { return 1; } return 0; } [Update] I have identified the problem - for some reason, although argc is correct, the elements of argv are empty strings. I put this little code snippet to print out the argv items - and was horrified to see that they were all empty. for (int i=0; i< argc; i++){ std::string s(argv[i]); //required so I can see the damn variable in the debugger std::cout << s << std::endl; } Does anyone know what on earth is going on (or a hammer)?

  • C++ class with char pointers returning garbage

    - by JMP
    I created a class "Entry" to handle Dictionary entries, but in my main(), I create the Entry() and try to cout the char typed public members, but I get garbage. When I look at the Watch list in debugger, I see the values being set, but as soon as I access the values, there is garbage. Can anyone elaborate on what I might be missing? #include <iostream> using namespace std; class Entry { public: Entry(const char *line); char *Word; char *Definition; }; Entry::Entry(const char *line) { char tmp[100]; strcpy(tmp, line); Word = strtok(tmp, ",") + '\0'; Definition = strtok(0,",") + '\0'; } int main() { Entry *e = new Entry("drink,What you need after a long day's work"); cout << "Word: " << e->Word << endl; cout << "Def: " << e->Definition << endl; cout << endl; delete e; e = 0; return 0; }

  • Problem with multiple checkbox

    - by Pushpendra
    I am using a checkbox that has the name selectedids[], and I am trying to select all checkbox with the JavaScript but the code is not working. However, when I change the name of checkbox to selectedids it works but I can't do so because I need all the ids that are selected on the POSTED page. The checkbox is as follow. foreach($rows as $row) { <input type="checkbox" name="selectedids[]" value="<?php echo $row['id']; ?>" class="checkbox" /> ........ ........ } And the Java-script function is as follow function SetAllCheckBoxes(CheckValue) { var CheckValue=true; if(!document.forms['main']) return; var objCheckBoxes = document.forms['main'].elements['selectedids[]']; if(!objCheckBoxes) return; var countCheckBoxes = objCheckBoxes.length; if(!countCheckBoxes) objCheckBoxes.checked = CheckValue; else // set the check value for all check boxes for(var i = 0; i < countCheckBoxes; i++) objCheckBoxes[i].checked = CheckValue; } Please help me. Thanks in advance..

  • Why does the Maven goal "package" include the resources in the jar, but the goal "jar:jar" doesnt?

    - by Bernhard V
    Hi, when I package my project with the Maven goal "package", the resources are included as well. They are originally located in the directory "src/main/resources". Because I want to create an executable jar and add the classpath to the manifest, I'm using maven-jar-plugin. I've configured it as the following likes: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.2</version> <configuration> <archive> <manifest> <addClasspath>true</addClasspath> <mainClass>at.sozvers.stp.zpv.ekvkumsetzer.Main</mainClass> </manifest> </archive> </configuration> </plugin> Why won't the jar file created with "jar:jar" include my resources as well. As far as I'm concerned it should use the same directories as the "package" goal (which are in my case inherited from the Maven Super POM).
