• Move iFrame in the DOM using jQuery

  - by Josh

  My overall aim is to create an editor which I can skin using jQuery UI (by creating a custom toolbar which uses integration calls), using TinyMCE. Lets say I have a TinyMCE editor on a page. The actual editor is an iFrame contained inside a lot of horrible table code, which is also where the current (to be scrapped) toolbar is. I want just the iframe inside a div - ideally get rid of the table code. So...I want to transform: <table> <tr> <td><iframe id="xyz"></iframe></td> </tr> </table> into <div id="test"> <iframe id="xyz"></iframe> </div> So far, I've tried using: $('#xyz').clone(true).appendTo('#test'); Which clones the iframe, but no content inside it. Is there a way to make this work? If not, can I somehow strip the table code from around the iFrame away? If I cant do that, I'll think I'll have to keep the table code.

• Parsing data from txt file in J2ME

  - by CSFYPMAIL

  Basically I'm creating an indoor navigation system in J2ME. I've put the location details in a .txt file i.e. Locations names and their coordinates. Edges with respective start node and end node as well as the weight (length of the node). I put both details in the same file so users dont have to download multiple files to get their map working (it could become time consuming and seem complex). So what i did is to seperate the deferent details by typing out location Names and coordinates first, After that I seperated that section from the next section which is the edges by drawing a line with multiple underscores. Now the problem I'm having is parsing the different details into seperate arrays by setting up a command (while manually tokenizing the input stream) to check wether the the next token is an underscore. If it is, (in pseudocode terms), move to the next line in the stream, create a new array and fill it up with the next set of details. I found a some explanation/code HERE that does something similar but still parses into one array, although it manually tokenizes the input. Any ideas on what to do? Thanks Text File Explanation The text has the following format... <--1stSection--  /**   * Section one has the following format   * xCoordinate;yCoordinate;LocationName   */ 12;13;New York City 40;12;Washington D.C. ...e.t.c _________________________ <--(underscore divider) <--2ndSection--  /**   * Its actually an adjacency list but indirectly provides "edge" details.   * Its in this form   * StartNode/MainReferencePoint;Endnode1;distance2endNode1;Endnode2;distance2endNode2;...e.t.c   */ philadelphia;Washington D.C.;7;New York City;2 New York City;Florida;24;Illinois;71 ...e.t.c

• Calling a WPF Appliaction and modify exposed properties?

  - by Justin

  I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to. Right now I have a file *.Keys.Set which tells the appliaction (on open) to style itself according to that new style. I know this file could be passed as a command line argument into the appliaction. That would not be a problem. My concern is, is thier a way via a managed environment to change the properties of the executable as long as they are exposed properly, an example: 'Creates a new instance of the Keyboard Appliaction Dim e_key as new WpfAppliaction("C:\egt\components\keyboard.exe") 'Sets the style path e_key.SetStylePath("c:\users\joe\apps\me\default.keys.set") e_key.Refresh() 'Applies the style e_key.HideMenu() 'Hides the menu e_key.ShowDeck("PIN") 'Shows the custom "deck" of keyboard keys the developer 'Created in the style appliaction. ''work with events and resposne 'Clear the instance from memory e_key.close e_key.dispose e_key = nothing This would allow my application to become easily accessible to other Touch Screen Application Developers, allowing them to use my key_board and keep the functionality they need. It seems like it might be possible because (name of executable).application shows all the exposed functions, properties, and values. I just have never done this before. Any help would be appreciated, thank you in advance.

• Simple jQuery syntax help, don't know where I've gone wrong

  - by Jascination

  I'm having trouble with a jQuery code at the moment, I know WHERE the problem lies, but I don't know what the problem is exactly. Probably very basic, but I'm new to this. You can see a (non)working fiddle here: http://www.jsfiddle.net/CvZeQ/ Basically I want to set different .click function based on whatever is selected (I have 5 image maps, each with a different #mapname, and want each to pertain to a different variable (answer1, answer2, answer3...) so as to store the selected 'answer' for each map.) Here is the code I'm using for one of the maps: $(window).load(function(){ //Get cookies when page loaded var useranswers=$.cookie('survery'); useranswers= JSON.parse (useranswers); // do something with previous answers //#shape functions $('#shape area').hover( function(e){ $('#'+ this.alt).addClass('hover'); }, function(e){ $('#'+ this.alt).removeClass('hover'); } ).click( function(e){ $('img.selected-region').removeClass('selected-region'); }, function(e){ $('#'+ this.alt).addClass('selected-region'); }, function(e){ var answer1 = $(this).attr("class"); }); }); I know the problem lies somewhere with the .click function, but I'm not entirely sure what I've done wrong. Any help would be greatly appreciated.

• ruby on rails implement search with auto complete

  - by user429400

  I've implemented a search box that searches the "Illnesses" table and the "symptoms" table in my DB. Now I want to add auto-complete to the search box. I've created a new controller called "auto_complete_controller" which returns the auto complete data. I'm just not sure how to combine the search functionality and the auto complete functionality: I want the "index" action in my search controller to return the search results, and the "index" action in my auto_complete controller to return the auto_complete data. Please guide me how to fix my html syntax and what to write in the js.coffee file. I'm using rails 3.x with the jquery UI for auto-complete, I prefer a server side solution, and this is my current code: main_page/index.html.erb: <p> <b>Syptoms / Illnesses</b> <%= form_tag search_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search] %> <br/> <%= submit_tag "Search", :name => nil %> </p> <% end %> </p> auto_complete_controller.rb: class AutoCompleteController < ApplicationController def index @results = Illness.order(:name).where("name like ?", "%#{params[:term]}%") + Symptom.order(:name).where("name like ?", "%#{params[:term]}%") render json: @results.map(&:name) end end search_controller.rb: class SearchController < ApplicationController def index @results = Illness.search(params[:search]) + Symptom.search(params[:search]) respond_to do |format| format.html # index.html.erb format.json { render json: @results } end end end Thanks, Li

• Sending a password securely using gwt and app engine?

  - by user246114

  Hi, I set up session handling on a google app project. This is supposed to allow my users to login and maintain state across pages. I just dumped it into the default greeting service to try it out: public class GreetingServiceImpl extends RemoteServiceServlet implements GreetingService { public void sessionTest(String username) { HttpSession session = getThreadLocalRequest().getSession(false); session.setAttribute("username", username); } } then attempting to pull it out in my landing project.jsp page: <% String username = null; HttpSession mysession = request.getSession(false); if (mysession.getAttribute("username") != null) { username = (String)mysession.getAttribute("username"); } else { username = "(not logged in yet)"; } <p>You are: <%= username %> </p> %> It works, but I don't know how to send the data in sessionTest() securely. If I were sending the user's password in there too, it would be in the clear. This would be ok (I think) if I was using https, but google app engine does not allow you to use https under custom domains (like www.mysite.com), they have to be under the (mysite.appspot.com) domain. I'm kind of stuck here - how do we send passwords securely? If I was using php, I think I could use digest authentication (I'm not too experienced here) - can we do something like that with gwt + gae? Thanks

• Show only div of the product hovering in category grid with jQuery

  - by Dane

  On Magento, I'm trying to get avalable attributes per product in a new div (show/ hide onmouseover) as soon as I hover a product. Unfortunately, my jQuery code opens every div with the same name. I think, I need to do it with jQuery(this) but I tried it in a 1000 different ways, and it won't work. Maybe, somebody here can help me with a better code. jQuery(function() { jQuery('.slideDiv').hide().data('over', false); jQuery('#hover').hover(function() { jQuery('.slideDiv').fadeIn(); }, function() { // Check if mouse did not go over .dialog before hiding it again var timeOut = setTimeout(function() { if (!jQuery('.slideDiv').data('over')) { jQuery('.slideDiv').fadeOut(); clearTimeout(timeOut); } }, 100); }); // Set data for filtering on mouse events for #hover-here jQuery('.slideDiv').hover(function() { jQuery(this).data('over', true); }, function() { jQuery(this).fadeOut().data('over', false); }); }); The PHP just prints the attributes needed. <a href="#" id="hover">Custom Attributes</a> <div class="slideDiv"> <?php $attrs = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product); foreach($attrs as $attr) { if(0 == strcmp("shoe_size", $attr['attribute_code'])) { $options = $attr['values']; print "Größen:<br />"; foreach($options as $option) { print "{$option['store_label']}<br />"; } } } ?> </div> I added the script to [new link] http://jsfiddle.net/xsxfr/47/ so you can see there, that it is not working like this right now :(.

• WPF: How do I bind a Control to a formula composed of several dependency properties?

  - by Pablo

  Hi all, I'm working on Expression Blend and I'm currently designing a custom control which has a Grid with 5 rows inside, and also has two Dependency properties: "Value", and "Maximum". Three of the rows have fixed height, and what I'm trying to do is set the remaining rows height to "Value/Maximum" and "1-Value/Maximum" respectively. How do I go and do that? When I set the height to "Value" it seems to react, but when I go and set it to "Value/Maximum" it stops working. I'm still a bit new around WPF, so there must be another way to achieve what I'm intending, but after searching I couln't find my problem elsewhere. Code: <Grid x:Name="LayoutRoot" Width="Auto" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="32"/> <RowDefinition Height="{Binding Path=(Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="16"/> <RowDefinition Height="{Binding Path=(1-Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="32"/> </Grid.RowDefinitions> (...) By the way, Value is always a not negative double less than or equal to Maximum; so the result of the division will be number between 0.0 a 1.0. I want a "star" instead of "pixel" row height.

• Exceptions over remote methods

  - by Andrei Vajna II

  What are the best practices for exceptions over remote methods? I'm sure that you need to handle all exceptions at the level of a remote method implementation, because you need to log it on the server side. But what should you do afterwards? Should you wrap the exception in a RemoteException (java) and throw it to the client? This would mean that the client would have to import all exceptions that could be thrown. Would it be better to throw a new custom exception with fewer details? Because the client won't need to know all the details of what went wrong. What should you log on the client? I've even heard of using return codes(for efficiency maybe?) to tell the caller about what happened. The important thing to keep in mind, is that the client must be informed of what went wrong. A generic answer of "Something failed" or no notification at all is unacceptable. And what about runtime (unchecked) exceptions?

• How to change Hibernate´s auto persistance strategy

  - by Kristofer Borgstrom

  I just noted that my hibernate entities are automatically persisted to the database (or at least to cache) before I call any save() or update() method. To me this is a pretty strange default behavior but ok, as long as I can disable it, it´s fine. The problem I have is I want to update my entity´s state (from 1 to 2) only if the entity in the database still has the state it had when I retrieved [1] (this is to eliminate concurrency issues when another server is updating this same object). For this reason I have created a custom NamedQuery that will only update the entity if state is 1. So here is some pseudo-code: //Get the entity Entity item = dao.getEntity(); item.getState(); //==1 //Update the entity item.setState(2); //Here is the problem, this effectively changes the state of my entity braking my query that verifies that state is still == 1. dao.customUpdate(item); //Returns 0 rows changes since state != 1. So, how do I make sure the setters don´t change the state in cache/db? Thanks, Kristofer

• How can I post an array of string to ASP.NET MVC Controller without a form?

  - by rodbv

  Hi there, I am creating a small app to teach myself ASP.NET MVC and JQuery, and one of the pages is a list of items in which some can be selected. Then I would like to press a button and send a List (or something equivalent) to my controller containing the ids of the items that were selected, using JQuery's Post function. I managed to get an array with the ids of the elements that were selected, and now I want to post that. One way I could do this is to have a dummy form in my page, with a hidden value, and then set the hidden value with the selected items, and post that form; this looks crufty, though. Is there a cleaner way to achieve this, by sending the array directly to the controller? I've tried a few different things but it looks like the controller can't map the data it's receiving. Here's the code so far: function generateList(selectedValues) { var s = { values: selectedValues //selectedValues is an array of string }; $.post("/Home/GenerateList", $.toJSON(s), function() { alert("back") }, "json"); } And then my Controller looks like this public ActionResult GenerateList(List<string> values) { //do something } All I managed to get is a "null" in the controller parameter... Any tips?

• Toolbar to modify displayed html/content in IE / Firefox / Chrome.

  - by JP

  Hi, I want to create toolbar, whose functionality would be: Whenever the toolbar is "On/Activated", all pages should be parsed by a function, and the modified html should be displayed. [Example: i) There was this skype toolbar that would recognize phone-numbers in pages and automatically add skype links ii) If you have used MacAfee / Alexa toolbars, they modify the search results page displayed by Google My functionality would a lot simpler though] I want to create this for all browsers (though answers/pointers to any one platform would be appreciated). Please note that I am new to toolbar development, so detailed pointers from basics would be very helpful. I have heard to GreaseMonkey. However, if I can do it in a more "basic" way, it would be very helpful. (Alternately, tips to make a "custom" toolbar using GreaseMonkey would be welcome - though I would like to do away with ability to add scripts, etc. Also I installed greasemonkey and it does show up as a toolbar in FF/IE at all! In IE, there is separate executable to add scripts - I want a standalone toolbar with ON/OFF facility in the browser). Thanks much! Regards, JP

• Where should test classes be stored in the project?

  - by limc

  I build all my web projects at work using RAD/Eclipse, and I'm interested to know where do you guys normally store your test's *.class files. All my web projects have 2 source folders: "src" for source and "test" for testcases. The generated *.class files for both source folders are currently placed under WebContent/WEB-INF/classes folder. I want to separate the test *.class files from the src *.class files for 2 reasons:- There's no point to store them in WebContent/WEB-INF/classes and deploy them in production. Sonar and some other static code analysis tools don't produce an accurate static code analysis because it takes account of my crappy yet correct testcase code. So, right now, I have the following output folders:- "src" source folder compiles to WebContent/WEB-INF/classes folder. "test" source folder compiles to target/test-classes folder. Now, I'm getting this warning from RAD:- Broken single-root rule: A project may not contain more than one output folder. So, it seems like Eclipse-based IDEs prefer one project = one output folder, yet it provides an option for me to set up a custom output folder for my additional source folder from the "build path" dialog, and then it barks at me. I know I can just disable this warning myself, but I want to know how you guys handle this. Thanks.

• Can I transform this asynchronous java network API into a monadic representation (or something else

  - by AlecZorab

  I've been given a java api for connecting to and communicating over a proprietary bus using a callback based style. I'm currently implementing a proof-of-concept application in scala, and I'm trying to work out how I might produce a slightly more idiomatic scala interface. A typical (simplified) application might look something like this in Java: DataType type = new DataType(); BusConnector con = new BusConnector(); con.waitForData(type.getClass()).addListener(new IListener<DataType>() { public void onEvent(DataType t) { //some stuff happens in here, and then we need some more data con.waitForData(anotherType.getClass()).addListener(new IListener<anotherType>() { public void onEvent(anotherType t) { //we do more stuff in here, and so on } }); } }); //now we've got the behaviours set up we call con.start(); In scala I can obviously define an implicit conversion from (T = Unit) into an IListener, which certainly makes things a bit simpler to read: implicit def func2Ilistener[T](f: (T => Unit)) : IListener[T] = new IListener[T]{ def onEvent(t:T) = f } val con = new BusConnector con.waitForData(DataType.getClass).addListener( (d:DataType) => { //some stuff, then another wait for stuff con.waitForData(OtherType.getClass).addListener( (o:OtherType) => { //etc }) }) Looking at this reminded me of both scalaz promises and f# async workflows. My question is this: Can I convert this into either a for comprehension or something similarly idiomatic (I feel like this should map to actors reasonably well too) Ideally I'd like to see something like: for( d <- con.waitForData(DataType.getClass); val _ = doSomethingWith(d); o <- con.waitForData(OtherType.getClass) //etc )

• Pre Project Documentation

  - by DeanMc

  I have an issue that I feel many programmers can relate to... I have worked on many small scale projects. After my initial paper brain storm I tend to start coding. What I come up with is usually a rough working model of the actual application. I design in a disconnected fashion so I am talking about underlying code libraries, user interfaces are the last thing as the library usually dictates what is needed in the UI. As my projects get bigger I worry that so should my "spec" or design document. The above paragraph, from my investigations, is echoed all across the internet in one fashion or another. When a UI is concerned there is a bit more information but it is UI specific and does not relate to code libraries. What I am beginning to realise is that maybe code is code is code. It seems from my extensive research that there is no 1:1 mapping between a design document and the code. When I need to research a topic I dump information into OneNote and from there I prioritise features into versions and then into related chunks so that development runs in a fairly linear fashion, my tasks tend to look like so: Implement Binary File Reader Implement Binary File Writer Create Object to encapsulate Data for expression to the caller Now any programmer worth his salt is aware that between those three to do items could be a potential wall of code that could expand out to multiple files. I have tried to map the complete code process for each task but I simply don't think it can be done effectively. By the time one mangles pseudo code it is essentially code anyway so the time investment is negated. So my question is this: Am I right in assuming that the best documentation is the code itself. We are all in agreement that a high level overview is needed. How high should this be? Do you design to statement, class or concept level? What works for you?

• Vector does reallocation on every push_back

  - by Amrish

  IDE - Visual Studio 2008, Visual C++ I have a custom class Class1 with a copy constructor to it. I also have a vector Data is inserted using the following code Class1* objClass1; vector<Class1> vClass1; for(int i=0;i<1000;i++) { objClass1 = new Class1(); vClass1.push_back(*objClass1); delete objClass1; } Now on every insert, the vector gets re-allocated and all the existing contents are copied to new locations. For example, if the vector has 5 elements and if I insert the 6th one, the previous 5 elements along with the new one gets copied to a new location (I figured it out by adding log statements in the copy constructors.) On using reserve(), this however does not happen as expected! I have the following questions Is it mandatory to always use the reserve statement? Does vector does a reallocation every time I do a push_back; or does it happen because I am debugging?

• SharePoint Lists.asmx's UpdateListItems() returns too much data

  - by Philipp Schmid

  Is there a way to prevent the UpdateListItems() web service call in SharePoint's Lists.asmx endpoint from returning all of the fields of the newly created or updated list item? In our case an event handler attached to our custom list is adding some rather large field values which are turned to the client unnecessarily. Is there a way to tell it to only return the ID of the newly created (or updated) list item? For example, currently the web service returns something like this: <Results xmlns="http://schemas.microsoft.com/sharepoint/soap/"> <Result ID="1,Update"> <ErrorCode>0x00000000</ErrorCode> <z:row ows_ID="4" ows_Title="Title" ows_Modified="2003-06-19 20:31:21" ows_Created="2003-06-18 10:15:58" ows_Author="3;#User1_Display_Name" ows_Editor="7;#User2_Display_Name" ows_owshiddenversion="3" ows_Attachments="-1" ows__ModerationStatus="0" ows_LinkTitleNoMenu="Title" ows_LinkTitle="Title" ows_SelectTitle="4" ows_Order="400.000000000000" ows_GUID="{4962F024-BBA5-4A0B-9EC1-641B731ABFED}" ows_DateColumn="2003-09-04 00:00:00" ows_NumberColumn="791.00000000000000" xmlns:z="#RowsetSchema" /> </Result> ... </Results> where as I am looking for a trimmed response only containing for example the ows_ID attribute: <Results xmlns="http://schemas.microsoft.com/sharepoint/soap/"> <Result ID="1,Update"> <ErrorCode>0x00000000</ErrorCode> <z:row ows_ID="4" /> </Result> ... </Results> I have unsuccessfully looked for a resource that documents all of the valid attributes for both the <Batch> and <Method> tags in he updates XmlNode parameter of UpdateListItems() in the hope that I will find a way to specify the fields to return. A solution for WSS 3.0 would be preferable over an SP 2010-only solution.

• Extend legacy site with another server-side programming platform best practice

  - by Andrew Florko

  Company I work for have a site developed 6-8 years ago by a team that was enthusiastic enough to use their own private PHP-based CMS. I have to put dynamic data from one intranet company database on this site in one week: 2-3 pages. I contacted company site administrator and she showed me administrative part - CMS allows only to insert html blocks & manage site map (site is deployed on machine that is inside company & fully accessible & upgradeable). I'm not a PHP-guy & I don't want to dive into legacy hardly-who-ever-heard-about CMS engine I also don't want to contact developers team, 'cos I'm not sure they are still present and capable enough to extend this old days site and it'll take too much time anyway. I am about to deploy helper asp.net site on IIS with 2-3 pages required & refer helper site via iframe from present site. New pages will allow to download some dynamic content from present site also. Is it ok and what are the pitfalls with iframe approach?

• Generating a python file

  - by fema

  Hi! I'm havin issues with python (imo python itself is an issue). I have a txt file, it contains a custom language and I have to translate it to a working python code. The input: import sys n = int(sys.argv[1]) ;;print "Beginning of the program!" LOOP i in range(1,n) {print "The number:";;print i} BRANCH n < 5 {print n ;;print "less than 5"} The wanted output looks exactly like this: import sys n = int(sys.argv[1]) print "Beginning of the program!" for i in range(1,n) : print "The number:" print i if n < 5 : print n print "less than 5" The name of the input file is read from parameter. The out file is out.py. In case of a wrong parameter, it gives an error message. The ;; means a new line. When I tried to do it, I made an array, I read all the lines into it, split by " ". Then I wanted to strip it from the marks I don't need. I made 2 loops, one for the lines, one for the words. So then I started to replace the things. Everything went fine until it came to the } mark. It finds it, but it can not replace or strip it. I have no more idea what to do. Could someone help me, please? Thanks in advance!

• Can the Visual Studio (2010) Command Window handle "external tools" with project/solution relative p

  - by ee

  I have been playing with the Command Window in Visual Studio (View-Other Windows-Command Window). It is great for several mouse-free scenarios. (The autocompleting file "Open" command rocks in a non-trivial solution.) That success got me thinking and experimenting: Possibility 1.1: You can use the Alias commands to create custom commands Possibility 1.2: You can use the Shell command to run arbitrary executables and specify parameters (and pipe the result to the output or command windows) Possibility 2: A previously setup external tool definition (with project-relative path variables) could be run from the command window What I am stuck on is: There doesn't appear to be a way to send parameters to an aliased command (and thus the underlying Shell call) There doesn't appear to be a way to use project/solution relative paths ($SolutionDir/$ProjectDir) on a Shell call Using absolute paths in Shell works, but is fragile and high-maintenance (one alias for each needed use case). Typically you want the command to run against a file relative to your project/solution. It seems you can't run the traditional external tools (Tools-External Tools...) in the command window Ultimately I want the external tool functionality in the command window in some way. Can anyone see a way to do this? Or am I barking up the wrong tree? So my questions: Can an "external tool" of some sort (using relative project/solution path parameters) be used in the Command Window? If yes, How? If no, what might be a suitable alternative?

• What is an appropriate way to separate lifecycle events in the logging system?

  - by Hanno Fietz

  I have an application with many different parts, it runs on OSGi, so there's the bundle lifecycles, there's a number of message processors and plugin components that all can die, can be started and stopped, have their setup changed etc. I want a way to get a good picture of the current system status, what components are up, which have problems, how long they have been running for etc. I think that logging, especially in combination with custom appenders (I'm using log4j), is a good part of the solution and does help ad-hoc analysis as well as live monitoring. Normally, I would classify lifecycle events as INFO level, but what I really want is to have them separate from what else is going on in INFO. I could create my own level, LIFECYCLE. The lifecycle events happen in various different areas and on various levels in the application hierarchy, also they happen in the same areas as other events that I want to separate them from. I could introduce some common lifecycle management and use that to distinguish the events from others. For instance, all components that have a lifecycle could implement a particular interface and I log by its name. Are there good examples of how this is done elsewhere? What are considerations?
