• JQuery+Java setting field value with val() + single quote

  - by Fabio K

  I have a problem setting the value of a textarea element with jquery's val(). Basically, I have a JSP file which receives a string parameter called 'text'. Java code: String text = (String) request.getParameter('text'); Now I want my textarea element to receive this text: Javascript code: $('#textarea_id').val('<%=text%>'); It works when my text doesnt contain quotes single quotes (and possibly other chars). For example, for text = test' this error happens: Uncaught SyntaxError: Unexpected token ILLEGAL $('#textarea_id').val('test''); I hope you guys understand. I need a way to encode this value... i tried using escape so the quote is replaced by %27, but after unescaping its replaced again and the error happens. Thanks!

• WebView with NSShadow slowdown

  - by Rodrigo

  I have a webview that shows some animated boxes, but it slows down and lags horribly when I put a drop shadow in the view. Without the shadow, the webview contents animate smoothly. I achieved a similar effect as safari/chrome when you do a elastic scroll with the touchpad. Looks nice! But doesnt run as smooth as in my inspirations. Here is the snippet of the shadow setting: NSShadow *dropShadow = [[NSShadow alloc] init]; [dropShadow setShadowColor:[NSColor blackColor]]; [dropShadow setShadowOffset:NSMakeSize(0, 0)]; [dropShadow setShadowBlurRadius:5.0]; [webview setWantsLayer: YES]; [webview setShadow: dropShadow]; [dropShadow release]; -- My question is: How can I work around this problem?

• C++ Add this pointer to a container by calling it in base class constructor

  - by vivekeviv

  class Base { public: Base (int a, int b); private: int a,b; }; class Derived1 { public: Derived1():base(1,2){} }; similarly Derived2, Derived 3 which doesnt contain any data members on its own Now i need to contain these derived objects in a singleton, so i was thinking to call this in base constructor like Base::Base(int a, int b) { CBaseMgr::GetInstance()->AddtoVector(this); } so now if i construct Derived d1, d2, d3 etc. will the Singleton's container contain all derived objects? My doubt is can i do this adding of objects to container in base ctor or should i do in derived ctor.?

• Select one column from a row in hibernate

  - by ComfortablyNumb

  I am trying to do a simple query to get a unique result back in hibernate here is my code. public String getName(Integer id) { Session session = getSessionFactory().openSession(); String name = (String)session.createSQLQuery("SELECT name FROM users WHERE user_id = :userId").setParameter("userId", id).uniqueResult(); return name; } The name that is being returned is stored as HTML text that includes html syntacx language. I think this is what is causing the problem but it doesnt make sense I just want to return it as a string. It is only happening on this one field name, I can get every other field in the row but this one it gives me the error. I am getting an exception. The exception I am getting is No Dialect mapping for JDBC type: -1; nested exception is org.hibernate.HibernateException How do you query for a specific column on a row in hibernate?

• Git 1.7.10 asks me for github username and password

  - by Daniel Ruf

  Since I have the new version it doesnt ask me anymore for the password I set in my ssh key file. It asks now directly for a github username and password when I push every time. Is this a new feature of git or changed it in the past or is there something what changed on github? I tried to authenticate using ssh and the email and password from my ssh ke file and it worked. Github changed to smartftp and also changed the instructions for setting up repos https://github.com/blog/1104-credential-caching-for-wrist-friendly-git-usage https://help.github.com/articles/create-a-repo Saw it later, they use now https instead of the git protocol

• sql data source re binding question

  - by Keith

  In my gridview after an insert operation has been done I am filtering the sqldatasource by ID. I am getting an error that the item drop down box selected value is not in the list. To test my theory I created a new sql data source with only the select statement and after the insert operation I am binding it to my grid view and filtering by Id and I get my result. The question Having a second data source is not the solution so is it possible that there is some way to use sqldatasource1? what I tried is sqldatasource.databind() and gridview.databind() on the inserted and inserting metheds in many test cases but still that doesnt work. I dont have any filters applied on the original data source?

• How to test Guice Singleton?

  - by 01

  Guice Singletons are weird for me First I thought that IService ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); will work as singleton, but it returns ser=Service2@1975b59 ser=Service2@1f934ad its ok, it doesnt have to be easy. Injector injector = Guice.createInjector(); IService ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); works as singleton ser=Service2@1975b59 ser=Service2@1975b59 So i need to have static field with Injector(Singleton for Singletons) how do i pass to it Module for testing?

• How do I make a project built into a downloadable Cd?

  - by Dcurvez

  hi all I just got finished making my first project in visual studio 2008. what I want to do is put it on a CD and let another person run it. I went to the clean and build and publish and all went well. When I took it to my friends house to put it on her computer..i never got a "download" and "install" screen. We were able to see it and use it on her computer (which is good cuz she doesnt have Visual on her machine) but I wanted her to be able to use it without keeping the CD in the drive. Is there some setup or something I have to do to make my program download and install? The whole shibang was all done with starting a new windows application..and then just adding windows forms to the original. Thanks :)

• How to load modules in Java

  - by gerardorn

  I'm building a server that loads modules. Each module is a .jar file. Inside the jar there's all the classes that the module needs. The server needs to read the jar, find the main class (it doesnt have the main method on it is just the class that makes the module work but not as a different program), build an object of that class and store it in a vector of modules so that it can acces to a specific module depending on the job to be done. How can I do that? As far as the server, it is listening and receiving request, but there's no modules to delegate the job to, since my vector of modules is empty.

• Javascript: setTimeout() - help needed

  - by ilkin

  Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

• Can I have multiple instance of the mandlebrot example in one program?

  - by yan bellavance

  Basically what I did is I took the Mandlebrot example and have 3 instances of it in my program. So the program would look like a mainwindow that has 3 mandlebrot widgets in it, one besides the other. Is it possible that GDB doesnt support debugging multiple intances of a classe that derives from qthread or is it thread-unsafe to do so? I don't have any problems at run-time but when I put breakpoints in a function called by the QThread run() function I get a segmentation fault. I can clearly see that the function doesn't complete before returning to the breakpoint ie I the program stops at the breakpoint, I step into the lines of codes one by one but after a couple of instructions another thread startS using the function(even though they are different instances).

  - by Fiona

  Hello, I have a layer which opens up as a tooltip everytime I hover a button. I simply did that by creating a JS function which displays or hides the layer. Now, I am not a pro in JavaScript. My problem is the following: when the button is scrolled towards the top oft he screen I want the tooltip opening below – and if the button is near the bottom of the screen I want the tooltip opening above. Right now I just did it with absolute positioning. But obviously that doesnt do the trick. Who can help? Thanks!

• computational puzzles (brute force)

  - by acidzombie24

  Not that i need it but it was interesting to hear someone speak about their server and protecting it from DOS attack by having a puzzle that the client must solve before the server will do anything (it doesnt do allocations or make a session unless solved). The person also said puzzles can be made to take a quick amount of time or long. And they are easy to check if it is solve correctly but difficult to solve. What are these puzzles? I never heard of one. Can someone give an example (link?)

• Creating objects and referencing before saving object to db

  - by Flexo

  Sorry about the vague title, but i didnt know how to ask the question in one line :) I have an order with nested itemgroups that again have nested items. the user specify the amount of item that he would like to have in each itemgroup. I would like to create these items in the create method of the orders controller when the order itself is being created. I kinda have 2 problems here. First, how do i set the reference of the items, or better yet, put the items into the @order object so they are saved when the @order is saved? the items are being stored in the db as the code is now, but the reference is not set because the order is not stored in the db yet so it doesnt have an id yet. Second, im not sure im using the correct way to get the id from my itemgroup. @order = Order.new(params[:order]) @order.itemgroups.each do |f| f.amount.times do @item = Item.new() @item.itemgroup_id = f.id @item.save end end
