  • List of items with same values

    - by user559780
    I'm creating a list of items from a file BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream("H:/temp/data.csv"))); try { List<Item> items = new ArrayList<Item>(); Item item = new Item(); String line = null; while ((line = reader.readLine()) != null) { String[] split = line.split(","); item.name = split[0]; item.quantity = Integer.valueOf(split[1]); item.price = Double.valueOf(split[2]); item.total = item.quantity * item.price; items.add(item); } for (Item item2 : items) { System.out.println("Item: " + item2.name); } } catch (IOException e) { reader.close(); e.printStackTrace(); } Problem is the list is displaying the last line in the file as the value for all items.

  • Grid forms in Rails

    - by KandadaBoggu
    I am trying to create a grid form for a survey question. value1 value2 value3 option 1 x option 2 x option 3 x Each cell in the grid is a radio button and the radio buttons in a row belong to one radio button group. My models: class Question # title has_many :answers end class Answer # name, position, atype(row/col) end I am struggling to come up with a Rails approach for creating such a form. To complicate the issue user can save the semi-completed form and complete it at a later time. What is the best approach for this problem?

  • Attach 1 or more (non image) files to rails application, with having to install an image-processing

    - by Hinchy
    Hi all, I'm currently learning rails by creating a simple project management app. I've gotten to the point where I would like to be allow a user upload multiple files - pdfs, docs, xls etc. The user only needs to be able to attach one file at a time, but the possibilty to have multiple documents associated with a project is a must. I've spent quite a lot of time researching my options, and it appears the two main plugins are attachment_fu and paperclip. From what I've read though, these appear to concentrate specifically on the upload and subsequent resizing of images, something I couldn't care less about. Is there a simpler way to achieve what I'm trying? Thank you all in advance.

  • Save the contents of manipulated div to a variable and pass to php file

    - by Danielle Zarcaro
    I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution. If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest. Any help would be greatly appreciated.

  • How do I add a loading indicator to my page while my iframe loads?

    - by keybored
    I am currently creating a page where upon clicking a link an iframe is inserted into a div and it's contents loaded. I do this using the following jQuery call: $('#mydiv').html('<iframe src="sourcelink.html" frameborder="0" width="760" height="2400" scrolling="no"></iframe>'); Sometimes the source content loads very slowly and, as a result, it looks like nothing is happening. I would like to have a simple loading animation while the content is loading while the iframe's content loads. When the iframe finishes loading it's content should pop in and the loading animation should go away. I've been considering a couple ways I could do this (e.g. having a separate loader div to simply swap the two in and out) but I'm not sure of what the 'best' approach to solving this problem is. Perhaps I shouldn't be using .html()? I'm open to suggestion if there is a more correct solution.

  • Understanding NoSQL Data Modeling - blog application

    - by Rushabh RajeshKumar Padalia
    I am creating an blogging application in Node.js + MongoDB Database. I have used relational Database like MySQL before but this is my first experience with NoSQL database. So I would like to conform my MongoDB data models before I move further. I have decided my blogDB to have 3 collections post_collection - stores information about that article comment_collection - store information about comments on articles user_info_collection - contains user inforamtion PostDB { _"id" : ObjectID(...), "author": "author_name", "Date": new Date(....), "tag" : ["politics" , "war"], "post_title": "My first Article", "post_content": "Big big article" "likes": 23 "access": "public" } CommentDB { "_id" : Objectid(...), "POST": "My First Article", "comment_by": "User_name", "comment": "MY comments" } UserInfoDB { "_id": ObjectID(...), "user": "User_name", "password": "My_password" } I would appreciate your comments.

  • How to access website CMS with only access to database

    - by user1741615
    I have a website that uses an "in-house" cms and I don't know the login details. The platform itself doesn't have the "reset your password" functionality. I do have access to ftp and phmyadmin and I found the SQL table containing the user details, but of course the password is MD5 encryption. I tried manually creating a user in php my admin and filling in a password encrypted in MD5 (used a md service online for that), but it still doesn't work. Does anybody know other tricks I can use? Thanks.

  • advanced search with mysql

    - by Arsenal
    I'm creating a search function for my website where the user can put in anything he likes in a textfield. It get's matched against anything (name, title, job, car brand, ... you name it) I initially wrote the query with an INNER JOIN on every table that needed to be searched. SELECT column1, column2, ... FROM person INNER JOIN person_car ON ... INNER JOIN car ... This ended up in a query with 6 or 8 INNER JOINs, and a whole lot WHERE ... LIKE '%searchvalue%' Now this query seems to cause a time'out in MySql, and I even got a warning from my hosting provider that the queries just taking up too many resources. Now obviously I'm doing this very wrong, but I was wondering how the correct approach to these kind of search functions is. Thanks!

  • Custom service application - proxy stopped

    - by Jonesie
    Ive created a custom service app using samples from Tony Bierman and MS. I can see the application in central admin, I can create a new service app from it, the create page works, the manage page is blank and I don't have a properties page. I havent yet tried using the beast, I just want to get the deployment and admin stuff working first. However, after creating it, I see the Service app has started but the app proxy is stopped. I dont know if this is a problem or not but I cant find anywhere to start it. Should I worry?

  • How could I use AJAX to create a Json data source .txt file?

    - by Adam
    I'm creating a form that collects standard information about customers. When the user hits save, I would like to create a .txt file that would be used to later retrieve all of the data collected from customers. I'm using DataTables which is a jQuery plugin to display the data. The .txt file would be formatted to be saved as such: { "aaData": [ ["client 1 name","address","city","state","zip"], ["client 2 name","address","city","state","zip"], ["client 3 name","address","city","state","zip"], ... ["client x name","address","city","state","zip"] ] } Where "aaData": is used by DataTables. This is going to part of an iPhone app, so the data source has to be very small and not reliant on a constant connection to a server, so, essentially, a client-side data source. The .txt file has to also be updated when edited and saved, and then replaced every time it is downloaded.

  • Is INT the correct datatype for ABS(CHECKSUM(NEWID()))?

    - by Chad Sellers
    I'm in the process of creating unique customers ID's that is an alternative Id for external use. In the process of adding a new column "cust_uid" with datatype INT for my unique ID's, When I do an INSERT into this new column: Insert Into Customers(cust_uid) Select ABS(CHECKSUM(NEWID())) I get a error: Could not create an acceptable cursor. OLE DB provider "SQLNCLI" for linked server "SHQ2IIS1" returned message "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. I've check all data types on both tables and the only things that has changed is the new column in both tables. The update is being done on one Big @$$ table...and for reasons above my pay grade, we would like to have new uid's that are different form the one's that we currently have "so users don't know how many accounts we actually have." Is INT the correct datatype for ABS(CHECKSUM(NEWID())) ?

  • CSS Sprites : Mysterious Concept Explored ?

    - by Rachel
    I have 3 different images and now I want to create an sprite using css so that I am reducing HTTP Request. I am totally new to this concept and have not idea as to how to approach this. Can anyone suggest me what would be best bet for me ? Also I have seen there are some CSS Sprite generator engines where in you submit .zip folder containing your images and than they would combine it. I tried doing that but did not understood of what was happening and so any guidance regarding creating and using CSS sprites would be highly appreciated. Update: I have gone through the AList Part but it was not very clear to me. Can anyone explain the use case of CSS Sprites using an example ? Thanks.

  • Fetch a Rails ActiveRecord 'datetime' attribute as a DateTime object.

    - by Tobias Cohen
    I have an attribute in one of my models that contains a Date/Time value, and is declared using t.datetime :ended_on in my migrations. When I fetch this value using myevent.ended_on, I get a Time object. The problem is that when I try to use this attribute as an axis in a Flotilla chart, it doesn't work properly because Flotilla only recognizes dates as Date or DateTime objects. I thought about writing a virtual attribute that will convert the existing Time value to a DateTime, but I'm wary of doing this, since I've heard that Time can't handle dates later than 2040, and I don't wish to risk creating a "2040 bug" to worry about later. Is there any way I can persuade ActiveRecord to return DateTime objects for this attribute instead of Time objects?

Now i'm able to create new accounts in the database with hashed passwords. But how do i keep track that a user is logged in. Is generating a long random number and putting this with the userID in the database and cookie enough? Sorry for my rather bad english! Ty in advance :)

  • Flash AS3 for loop query

    - by jimbo
    I was hoping for a way that I could save on code by creating a loop for a few lines of code. Let me explain a little, with-out loop: icon1.button.iconLoad.load(new URLRequest("icons/icon1.jpg")); icon2.button.iconLoad.load(new URLRequest("icons/icon2.jpg")); icon3.button.iconLoad.load(new URLRequest("icons/icon3.jpg")); icon4.button.iconLoad.load(new URLRequest("icons/icon4.jpg")); etc... But with a loop could I have something like: for (var i:uint = 0; i < 4; i++) { icon+i+.button.iconLoad.load(new URLRequest("icons/icon"+i+"jpg")); } Any ideas welcome...

  • Simple RIA backend

    - by Jeremy
    I'm creating a prototype for a java web application. Frontend is a Swing-based java applet. Backend should be a type of web-service, that is called by applet. Backend should run inside a servlet container and should have its own security (username/password) database. I know, that Tomcat has its own user database (realm), but the app should have own. Web-services, in turn, carrying out app logic and database access (via Hibernate). I'm a newbie for a web development and I'm getting lost in a huge amount of the java web frameworks. Even just reading 'introduction' and 'getting started' documents takes a lot of time. So I need an advice which framework(s) are suitable for the task and not very complex for a quick start. Thank you

  • Placeholder containing dynamic table is empty unless I create table twice

    - by Mike O.
    I am dynamically creating a table that contains a textbox in each cell. The table is put in a placeholder control. Everything displays perfectly. The problem is when I go to retrieve the values entered in the cells. I have the code to generate the table in a separate method called CreateTable(). In order for my program to find a table in the placeholder when I go to save, I have to run CreateTable() in a postback event AND in the PageLoad event. If I call CreateTable() in only one of those places and I try to save, it says the placeholder is empty and, therefore, I cannot save the textbox contents. I've tried calling CreateTable() from InitLoad but that doesn't work because it needs to reference values from three static controls: 1 dropdown, 1 listbox, and 1 calendar control, which I don't believe have had their viewstate rendered yet. Anyone have any ideas? It would sure be nice not to have to double the number of database calls just to make this work.

  • How do you detach an array of strings from shared memory? C

    - by Tim
    I have: int array_id; char* records[10]; // get the shared segment if ((array_id = shmget(IPC_PRIVATE, 1, 0666)) == -1) { perror("Array Creating"); } // attach records[0] = (char*) shmat(array_id, (void*)0, 0); if ((int) *records == -1) { perror("Array Attachment"); } which works fine, but when i try and detach i get an "invalid argument" error. // detach int error; if( (error = shmdt((void*) records[0])) == -1) { perror(array detachment); } any ideas? thank you

  • Rails + RSpec problem

    - by FancyDancy
    I have just installed Rspec and Rspec-rails. When i try to run the test, it says: rake aborted! Command /opt/local/bin/ruby -I"lib" "/opt/local/lib/ruby/gems/1.8/gems/rspec-1.3.0/bin/spec" "spec/controllers/free_controller_spec.rb" --options "/Volumes/Trash/dev/app/trunk/spec/spec.opts" failed Full log here: http://pastie.org/939211 However, my second "test" application with sqlite works with it. I think the problem is in my DB. My ruby version is 1.8.7, i use mysql as database. My files: specs/spec_helper.rb config/environment.rb config/environments/test.rb List of my gems My test is just: require 'spec_helper' describe FreeController do it "should respond with success" do get 'index' response.should be_success end end I really can't understand the error, so i don't know how to fix it.. Additional question: should i use a fixtures and ActiveRecord, if i going to use Machinist for creating test data? What should i do to disable them?

  • SQL Server 2008 + expensive union all

    - by Tim Mahy
    Hi al, we have 5 tables over which we should query with user search input throughout a stored procedure. We do a union all of the similar data inside a view. Because of this the view can not be materialized. We are not able to change these 5 tables drastically (like creating a 6th table that contains the similar data of the 5 tables and reference that new one from the 5 tables). The query is rather expensive / slow what are our other options? It's allowed to think outside the box. Unfortunately I cannot give more information like the table/view/SP definition because of customer confidentiality... greetings, Tim

  • Call Contact list on non-standard Android phones

    - by sgarman
    I am creating a widget that you can assign a contact to onClick. I used the method that is described here. This works great on standard Android phones such as the Motorola Droid, HTC Nexus One and HTC G1. The problem is for users who are using devices such as the HTC Incredible or HTC Droid Eris (Both running Sense UI) and I imagine on other phones who's OS deviates from the vanilla flavor of Android. Using my current method I thought that the device's OS would hook into whatever that manufacture chose to use for their Contact system however users are being sent to a random list of numbers, not their Contact list. Does anyone have a suggestion on how to get those Contacts or is this just another example of the Android fragmentation issue? Any help or insight is greatly appreciated.

  • @Secured not working

    - by user3640507
    I am new to spring and trying to implement Role based authorization with the help of @Secured annotation. I have a method which is specifically for ADMIN and I have written @Secured ("ROLE_ADMIN") to secure it. @Secured ("ROLE_ADMIN") public void HelloUser(String name) { System.out.println("Hello ADMIN"); } Now when I call this method by creating a class object it gets called eventhough user dont have ADMIN authority But when I dont create an object and use @autowired annotation instead then it works i.e User is not allowed to access this method. In my security.xml as well as servlet.xml I have added <global-method-security secured-annotations="enabled" /> Can some one please tell me where I am going wrong or is this the natural behaviour in spring ?

  • Securing input of private / protected methods?

    - by ts
    Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.
