  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

  • Program output to file in Java (and reading it again)

    - by Cohagen
    I have a large main method in an IO class which creates objects from four different classes in my program (which all use one another to some extent). My main method takes all info in using a scanner, from the console window, and uses this info to call the constructors and methods in the other classes. As this is my first full program in Java I have been focussed on making the main method work via the console, without properly considering file input and output. I cannot see an easy way of making that work now. Ideally what I require is some way of writing everything I input to the console while running the main method to a file, in a format that can be read again and inputed back through the main method? I have refrained from posting the main method as it is 250+ lines long, but will post any relevant parts of it if required. Any help appreciated

  • Objective-C why doesn't my array of array works?

    - by Quetsche
    This is probably a completely stupid question, but i'm pretty new at objective-C and programing in general. i'm trying to make an array of arrays but can't manage to make it work : @interface ArraysAndDicts : NSObject { NSMutableArray * mySimpleArray; NSMutableArray * myComplicatedArray; } the implementation : -(void)generateValueForArrayOfArrays { [self generateValueForArray]; //this generates an array with 5 elements 'mySimpleArray' [myComplicatedArray addObject:mySimpleArray]; NSMutableArray * mySecondaryArray = [[NSMutableArray alloc] init]; [mySecondaryArray addObject:@"twoone"]; [mySecondaryArray addObject:@"twotwo"]; [myComplicatedArray addObject:mySecondaryArray]; (i edited out all the NSLogs for clarity) When running my app, the console tells me : mySecondaryArray count = 2 mySimpleArray count = 5 myComplicatedArraycount = 0 So, i know there are other ways to make multidimensional arrays, but i'd really like to know why this doesn't work. Thank you.

  • PHP radio button check if null

    - by Dallox
    So in class we get this school task where we need to check if one of the fields in unfilled and display an error. No we did this but for some strange reason it doesnt display a error when a radio button is unchecked. (textfield null check works fine) I've tried with a friend many possabilities but they all doesnt seem to work. We have been stuck at this task for 2 hours. Now we have tried making seperate if's but that doesnt seem to work too. These are the important parts: <p> <input type="hidden" name="taal" value="false"> Choose a language <input type="radio" name="taal" value="N"> Dutch <input type="radio" name="taal" value="E"> English <input type="radio" name="taal" value="S"> Spanish if (@$_POST['taal'] == null){ echo "No Language gotten"; return; }

  • User HasOne ActiveToken, HasMany Tokens, how to setup in Rails?

    - by viatropos
    I have two simple models: class User < ActiveRecord::Base has_many :tokens # has_one doesn't work, because Token already stores # foreign id to user... # has_one :active_token, :class_name => "Token" # belongs_to doesn't work because Token belongs to # User already, and they both can't belong to each other # belongs_to :active_token, :class_name => "Token" end class Token < ActiveRecord::Base belongs_to :user end I want to say "User has_one :active_token, :class_name => 'Token'", but I can't because Token already belongs_to User. What I did instead was just manually add similar functionality to the user like so: class User < ActiveRecord::Base has_many :tokens attr_accessor :active_token after_create :save_active_token before_destroy :destroy_active_token # it belongs_to, but you can't have both belongs_to each other... def active_token return nil unless self.active_token_id @active_token ||= Token.find(self.active_token_id) end def active_token=(value) self.active_token_id = value.id @active_token = value end def save_active_token self.active_token.user = self self.active_token.save end def destroy_active_token self.active_token.destroy if self.active_token end end Is there a better way?

  • Network license control for a Java application

    - by user1461615
    I have been tasked with providing some form of network license control for a Java application. The app would be stored on a network drive and run from a client machine. The basic idea is that it will be able to work out how many times it is being run concurrently and prevent the N+1th user from running the software where N is the number of concurrent licenses the customer has purchased. Is this possible somehow with a Java application? I implemented a "solution" which relied on multi-cast UDP communication between the running instances of the application but this didn't work because on most networks this kind of communication is blocked by security measures. Is there a better way? I don't even mind if it requires JNI/JNA. N.B. The solution does not have to be that sophisticated or highly secure.

  • PHP and C# communication with Encrypt/Decrypt

    - by SilentWarrior
    Hello, I have been searching and cant find a consistent solution to my problem : I want to encrypt something in C# and decrypt it in PHP but also be able to encrypt in PHP and decrypt in C#, using the same key on both ends. All the solutions I found dont seem to work both ways, most of them only work on one language and then fail on the other, either by decrypting wrong or by blowing up the offsets. I would like to use TripleDES but it isnt a requirement, just want something relatively strong for plain text communication (will either use JSON or just plain key-value pairs for complex stuff). Thanks in advance PS: http://pastie.org/643106 this is what I have been testing with.

  • C# mysql one return last_insert_id

    - by Bernhard
    I am trying to create a method in which I can exequte mysql UPDATE, DELETE or INSERT query. The method must work when with an INSERT I ask or do not ask the last_insert_id(). Below is the code that I have at the moment: public int executeUID(MySqlCommand msCommand) { try { this.Open(); msCommand.Connection = this.msCon; return int.Parse(msCommand.ExecuteScalar().ToString()); } catch (MySqlException ex) { throw ex; } finally { this.Close(); } } The problem with this is is that when I use an insert query that returns a last_insert_id() the method works greatly. But when the query doesn't return an last_insert_id() the method malfunctions. How can I get this method to work?

  • Table naming convention?

    - by MattSlay
    In our manufacturing shop, each Employee hits the time clock every time they change Jobs or Machines (work centers) during their work day. Each record created in the Time Clock app has foreign keys that link the record to: the Employee, the Job, and the Machine which they are about to operate. I’m trying to determine the best name for this table… If I were tempted to call it ClockRecords or TimeClockRecords, why wouldn’t I also consider naming it JobTimeRecords, or why not MachineTimeRecords. Any ideas on a good name?

  • C++0x: how to get variadic template parameters without reference?

    - by Sydius
    Given the following contrived (and yes, terrible) example: template<typename... Args> void something(Args... args) { std::tuple<Args...> tuple; // not initializing for sake of example std::get<0>(tuple) = 5; } It works if you call it like so: int x = 10; something<int>(x); However, it does not work if you call it like this: int x = 10; something<int&>(x); Because of the assignment to 5. Assuming that I cannot, for whatever reason, initialize the tuple when it is defined, how might I get this to work when specifying the type as a reference? Specifically, I would like the tuple to be std::tuple<int> even when Args... is int&.

  • How suitable is a DVCS for the corporate environment?

    - by Matt Brailsford
    I've been using SVN for some time now, and am pretty happy with how it works (but I can't say I'm an expert, and I haven't really done much with branches and merging). However an opportunity has arisen to put in some new practises on a new team and so I thought I'd take a look at DVCSs to see if it's worth making the jump. The company I work for is a pretty standard company where we all work in the same location (or sometimes at home) and we want to keep a central store of all code. My question is: if all you are doing with a DVCS is creating a central hub that everyone pushes their changes to, is there really any benefit to moving to a DVCS and its extra overheads in this sort of environment?

  • Can't search in a certain field using solR

    - by intrance
    Hi, I'm setting up an environment using Nutch 1.0 + solR 1.4. In Nutch I configured the subcollection plugin which seems to work nicely. If I search as normal adding fl=* I can see the subcollection field is filled as intented. (something like <str name="subcollection">mysite.com</str>). My problem is, I would like to be able to search only in one or more given subcollections, but whenever my searchquery is something like q=subcollection:mysite.com it won't work. I've also tried to add a fl=* or searched in mysite* instead but I never get any results. Obviously solR "knows" the subcollection field, as it doesn't result with an error but simply whith an empty result. I'd be glad for any help

  • Adding custom fields to users in django

    - by Gaurav
    I am the create_user() function that Django provides to create my users. Also I want to store additional information about the users. So I tried following the instructions given at http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users but I cannot get it to work for me. Is there a step-by-step guide that I can follow to get this to work for me? Also, once I have added these custom fields, I would obviously need to add / edit / delete data from them. I cannot seem to find any instructions on how to do this.

  • Svn: how to remove all deleted files from repository ?

    - by Patrick
    I have a script in which I add all new files before to commit my working copy to my repository with this line: svn status | grep ^\? | awk '{print $2}' | xargs svn add I now want to add a line that delete from repository all deleted files in my working copy. In other terms, I cannot specify them one by one, and I need to detect them with svn status and then automatically remove them. However the line doesn't work. svn status | grep ^\! | awk '{print $2}' | xargs svn --force delete As you can see I've replaced "?" with "!" and "add" with "--force delete" Could you tell me why it doesn't work ? ps. I know it is a risky procedure. I've already discussed all about it. thanks thanks

  • Third Party Libraries and Technologies very Java Programmer must be aware of?

    - by kunjaan
    I agree that this is a very subjective question but as a student of Java , I get suggested good libraries and technologies for Java by my mentors at work. For example, I was not aware of Google Guice for Dependency Injection, awesomeness of Java Reflection APIs, ORMs like Hibernate or stuffs you could do with libraries like Hadoop. I want to collect and share some of the libraries that exemplifies good java programming (so that beginners like me could code walk and emulate the coding practice), teach unique concepts to Java (for example Dependency Injections or ORM) and/or are really interesting libraries that a student like me would get to do interesting projects on (eg. Hadoop). I redited this question 3 times to make it more specific : ). I am sorry if I am really not clear in my intentions. But some kind of a list of good concepts and third party libraries for Java could really help some of my intern friends here at work. Thank you.

  • 3 div independently relative and top aligned

    - by Knu
    I have 3 div top aligned that should be relative to a previous div (not between them so i can't use floats or position:inline-block either). If you set display:none on 2 divs the last one shouldn't move. I can't use position:absolute because there's a relative footer underneath. I tried using a wrapper but it can't work cause the height of the divs is not fixed. The height of the wrapper gets completely ignored anyway (by the following footer) unless Im using relative children. vertical-align:top doesn't work either. Any ideas?

  • Rewriting ASP.NET (.aspx) pages in Apache

    - by whitstone86
    I managed to get ASP.NET to work in Apache, as per http://weblogs.asp.net/israelio/archive/2005/09/11/424852.aspx but I'm unsure how to get it to rewrite pages, with a web.config file. I've tried using Google endlessly, but came to nothing. What's the best solution for me to rename my pages, e.g. mytestpage.aspx to mytestpage.htm Also, anyone know how to get IIS and MySQL working? I've tried but I'm struggling to get it to work. I did this simply because I needed multiple sites on port 80 on localhost, and the website I'm developing is not suited to PHP. IIS is installed, but not being used at the moment. Thanks

  • How to implement a book preview (2 page spread) without using Flash?

    - by littlejim84
    I'm looking into a solution for work, where you have a two page spread of the book to preview. Either side of this, you can hover in the corner to create a pseudo-flip and then click the mouse button to actually turn the page. I know there is many Flash solutions out there, but in this case we cannot use it... So we are looking for a possible solution that can work across all major browsers (yes, including IE6)... I looked a few canvas solutions, but with Google's canvas extension for IE, these will terribly slow. So was thinking about an SVG/VML solution, like Raphael Javascript library. This could be good, but then trying to look into how to code this, without examples, could be a challenge with the time constraint. Is there a solution out there that fits (or almost fits) this problem?

  • CakePHP delete() function is not working

    - by Logic Artist
    Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

  • Working with Japanese filenames in PHP 5.3 and Windows Vista?

    - by Jon
    I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with: header('Content-Type: text/html; charset=UTF-8'); setlocale(LC_ALL, 'en_US.UTF8'); mb_internal_encoding("UTF-8"); At the top (Exporting as plain text until I can sort this out). What can I do? I need this to work and I don't have much time.
