  • jQuery to get the text attribute of a checkbox

    - by Andriyev
    Hi I'm adding a check box to a page using the following statement; <script language="C#" runat="server"> protected void Page_Load ( object src, EventArgs e ) { if (!IsPostBack) { CheckBox XChkBox = new CheckBox(); //instance of System.Web.UI.WebControls.CheckBox XChkBox.ID = "someId" XChkBox.Text = "someText" somePlaceHolder.Controls.Add(XChkBox); } } </script> I need to get the Text attribute of that check box on click. I tried $(this).attr('Text'); inside $('input[type=checkbox]').click(function(){}); but it returns undefined. Where am I going wrong? Please suggest. cheers

  • Why & When should I use SPARSE COLUMN? (SQL SERVER 2008)

    - by priyanka.sarkar
    After going thru some tutorials on SQL SERVER 2008's new feature SPARSE COLUMN, I have found that it doesn't take any space if the column value is 0 or null but when there is a value, it takes 4 times the space a regular(non sparse) column holds. If my understanding is correct, then why I will go for that at the time of database design? And if I use that, then at what situation so I be? Also out of curiosity, how come no space get's reserve when a column is defined as sparse column(I mean to say, what is the internal implementation for that) Thanks in advance

  • How to optimize Dijkstra algorithm for a single shortest path between 2 nodes?

    - by Nazgulled
    Hi, I was trying to understand this implementation in C of the Dijkstra algorithm and at the same time modify it so that only the shortest path between 2 specific nodes (source and destination) is found. However, I don't know exactly what do to. The way I see it, there's nothing much to do, I can't seem to change d[] or prev[] cause those arrays aggregate some important data for the shortest path calculation. The only thing I can think of is stopping the algorithm when the path is found, that is, break the cycle when mini = destination when it's being marked as visited. Is there anything else I could do to make it better or is that enough? P.S: I just noticed that the for loops start at 1 until <=, why can't it start at 0 and go until <?

  • Should I distinguish OpenIDs based on protocol prefix or not? http vs https

    - by Joannes Vermorel
    I have implemented a straightforward OpenID support for my ASP.NET app with DotNetOpenAuth. Yet I recently realized that the implementation was treating http://johndoe.example.com/ as a distinct user compared to https://johndoe.example.com. This lead to quite a few confused users. I am unsure what to do at this point. Is this a bug or a feature? Indeed, I can consider this behavior as a feature: if the user specifies the HTTPS, the user might not want the system to accept HTTP auth in the first place. On the other hand: if the user specifies HTTPS out of sheer cluelessness (the casual web visitor is clueless concerning the purpose of the "S" part), then rejecting it's authentication attempt is confusing. What is considered as the best practice?

  • Is there anyway of making json data readable by a Google spider?

    - by leeand00
    Is it possible to make JSON data readable by a Google spider? Say for instance that I have a JSON feed that contains the data for an e-commerce site. This JSON data is used to populate a human-readable page in the users browser. (I.E. The translation from JSON data to human displayed page is done inside the users browser; not my choice, just what I've been given to work with, its an old legacy CGI application and not an actual server-side scripting language.) My concern here is that, the google spiders will not be able to pickup/directly link to the item in question when a user clicks on it in google, being presented with an index page full of all the items, rather than being linked directly to the item they clicked on. Is there anyway of "informing" the google spider in the JSON that what they should feed the user a different link?

  • How do I use the Silicon Laboratories IDE with SDCC?

    - by David Cary
    I'm thinking about using a microcontroller with an 8051 core from Silicon Laboratories. I hope that I can use C rather than assembly language, so I installed SDCC. I installed the "Silicon Laboratories IDE" to download the executable binaries to the on-chip Flash program memory. It also supposedly can be set up (under the Project Tool Chain Integration menu) to use "any" 8051 compiler. I tried to set it up to use SDCC, but every time I hit the "Assemble/Compile File" button it tells me "Compiler process did not sucessfully complete." How do I get new C code I write onto the SiLabs C8051F310 chip? Is there a web site with a step-by-step HOWTO? (Would it be easier to use a MAKEFILE that calls SDCC, only using the "Silicon Laboratories IDE" for the very last step of downloading the executable binary to the chip?)

  • Help with MVC controller: passing a string from view to controller

    - by 109221793
    Hi guys, I'm having trouble with one particular issue, I was hoping someone could help me out. I've completed the MVC Music Store tutorial, and now I'm trying to add some administrator functionality - practice as I will have to do this in an MVC application in my job. The application is using the aspnet membership api, and what I have done so far is created a view to list the users. What I want to be able to do, is click on the users name in order to change their password. To try and carry the username to the changeUserPassword controller (custom made). I registered a new route in the global.asax.cs file in order to display the username in the URL, which is working so far. UserList View <%: Html.RouteLink(user.UserName, "AdminPassword", new { controller="StoreManager", action="changeUserPassword", username = user.UserName }) %> Global.asax.cs routes.MapRoute( "AdminPassword", //Route name "{controller}/{action}/{username}", //URL with parameters new { controller = "StoreManager", action = "changeUserPassword", username = UrlParameter.Optional} ); So now the URL looks like this when I reach the changeUserPassword view: http://localhost:51236/StoreManager/changeUserPassword/Administrator Here is the GET changeUserPassword action: public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } I wanted to store the username in ViewData as I would like to use it in the GET changeUserPassword for display purposes, and also as a hidden value in the form. This is in order to pass it through to enable me to reset the password. Having debugged through the code, it seems that 'username' is null. How can I get this to work so that the username carries over from the Html.RouteLink, to the changeUserPassword action? Any help would be appreciated :) Here is my complete code: UserList.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Web.Security.MembershipUserCollection>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> UserList </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>UserList</h2> <table> <tr> <th>User Name</th> <th>Last Activity date</th> <th>Locked Out</th> </tr> <%foreach (MembershipUser user in Model){ %> <tr> <td><%: Html.RouteLink(user.UserName, "AdminPassword", new { controller="StoreManager", action="changeUserPassword", username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> </table> </asp:Content> changeUserPassword.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<musicStoreMVC.ViewModels.ResetPasswordAdmin>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> changeUserPassword </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Change Password: <%: ViewData["username"] %></h2> <% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.Hidden("username",ViewData["username"]) %> <%: Html.LabelFor(model => model.password) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.password) %> <%: Html.ValidationMessageFor(model => model.password) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.confirmPassword) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.confirmPassword) %> <%: Html.ValidationMessageFor(model => model.confirmPassword) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> <div> <%: Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> My actions public ActionResult UserList() { var users = Membership.GetAllUsers(); return View(users); } public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); }

  • Efficient heaps in purely functional languages

    - by Kim
    As an exercise in Haskell, I'm trying to implement heapsort. The heap is usually implemented as an array in imperative languages, but this would be hugely inefficient in purely functional languages. So I've looked at binary heaps, but everything I found so far describes them from an imperative viewpoint and the algorithms presented are hard to translate to a functional setting. How to efficiently implement a heap in a purely functional language such as Haskell? Edit: By efficient I mean it should still be in O(n*log n), but it doesn't have to beat a C program. Also, I'd like to use purely functional programming. What else would be the point of doing it in Haskell?

  • PostScript versus PDF as an output format

    - by Brecht Machiels
    I'm currently writing a typesetting application and I'm using PSG as the backend for producing postscript files. I'm now wondering whether that choice makes sense. It seems the ReportLab Toolkit offers all the features PSG offers, and more. ReportLab outputs PDF however. Advantages PDF offers: transparancy better support for character encodings (Unicode, for example) ability to embed TrueType and even OpenType fonts hyperlinks and bookmarks Is there any reason to use Postscript instead of directly outputting to PDF? While Postscript is a full programming language as opposed to PDF, as a basic output format for documents, that doesn't seem to offer any advantage. I assume a PDF can be readily converted to PostScript for printing? Some useful links: Wikipedia: PDF Adobe: PostScript vs. PDF

  • NSTimer to fire while device is locked

    - by edie
    Hi, I'm currently creating an alarm. I use NSTimer to schedule my alarms. My problem is when the device was put into locked mode my NSTimer doesn't fire. I think that the NSTimer will not fire because my app goes to suspended state when it is lock. Can you help me find a solution to my problem? I've found some topics about UIBackgroundModes, but I don't know how it will help me. Thanks.. The problem in UILocalNotification is when the device was in silent, the sound will not be hear. My implementation was I'm using NSTimer to fire an alarm when the app is in foreground or device is locked but app currently running. When the applicationDidEnterBackground: is called I schedule the UILocalNotification as the alarm.

  • Is my form password being passed in clear text?

    This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site?

  • Programming related name for a kitten? [closed]

    - by andrhamm
    I am a programmer and I just got my first kitten. A Google search for nerdy/geeky cat names was unimpressive. She's a little black kitten with a very courageous and adventurous attitude! She has a little light gray spot on her chest which might turn white with time. Here she is on my Flickr Which name would you suggest? Which of these do you like? It should be something short that has a couple contrasting sounds so it stands out a bit when you say it. PHP is my favorite scripting language but it makes for a lousy name :P Java Pixel Perl Ruby Gizmo Mocha Thanks for the help!

  • How to use ORDER BY, LOWER .. in SQL SERVER 2008 with non-unicode languages

    - by hgulyan
    Hi, The question is about Armenian. I'm using sql server 2005, collation SQL_Latin1_General_CP1_CI_AS, data mostly is in Armenian and we can't use unicode. I tested on ms sql 2008 with a windows collation for armenian language ( Cyrillic_General_100_ ), I have found here, ( http://msdn.microsoft.com/en-us/library/ms188046.aspx ) but it didn't help. I have a function, that orders hex values and lower function, which takes each char in string and covnerts it to it's lower form, but it's not acceptable solution, it works really slow, calling that functions on every column of a huge table. Is there any solution for this issue not using unicode and working with hex values manually?

  • Windows API GUI programming

    - by genesys
    Hi! I'm working on a Project with outdated, very old looking GUI (the used GUI framework is more than 10 years old) Since the used programming language is Eiffel, there are almost no good libraries for GUI development. Although Wrappers for C libraries exist, it's not that easy to wrap something like Qt with them. The current GUI framework uses the Windows API to create windows, widgets and so on. But as stated - it's very old. Now i would like to learn more about how to use the Windows API directly to create state of the art GUI's Can someone recommend any reading material? Thanks!

  • Why use Oracle Application Express for web app?

    - by Jack
    Hi all. I believe we're moving to Oracle Apex for future development. I've read about Oracle Apex on wikipedia and it's pro and con. It seem to me the con outweigh the pro but maybe I'm wrong. I get the sense that Oracle Apex is for DBA with little or no programing knowledge to setup a web app quickly sort like MS Access for none programmer. If you have Oracle Apex working experience, can you share your though? From wikipedia's entry, it doesn't seem like you need to know any programming language at all but just the PL/SQL? edit: Is Oracle Apex scalable? Can it handle traffic like Facebook's size? Thank. Jack

  • How can I update an expression in a Runt::Schedule object?

    - by Reid Beels
    Runt provides a Schedule class for managing collections of events, each represented by a temporal expression. The Schedule class provides an update method, cited in the release notes as "allowing clients to update existing expressions". The implementation of this method, however, simply calls a supplied block, providing the temporal expression for the specified event (as shown). # From lib/runt/schedule.rb:61 # # Call the supplied block/Proc with the currently configured # TemporalExpression associated with the supplied Event. # def update(event,&block) block.call(@elems[event]) end How is one expected to use this method to update an expression?

  • How can I efficiently group a large list of URLs by their host name in Perl?

    - by jesper
    I have text file that contains over one million URLs. I have to process this file in order to assign URLs to groups, based on host address: { 'http://www.ex1.com' = ['http://www.ex1.com/...', 'http://www.ex1.com/...', ...], 'http://www.ex2.com' = ['http://www.ex2.com/...', 'http://www.ex2.com/...', ...] } My current basic solution takes about 600 MB of RAM to do this (size of file is about 300 MB). Could you provide some more efficient ways? My current solution simply reads line by line, extracts host address by regex and puts the url into a hash. EDIT Here is my implementation (I've cut off irrelevant things): while($line = <STDIN>) { chomp($line); $line =~ /(http:\/\/.+?)(\/|$)/i; $host = "$1"; push @{$urls{$host}}, $line; } store \%urls, 'out.hash';

  • Why are alloc and init called separately in Objective-C?

    - by André Hoffmann
    Note: I'm relatively new to Objective-C and am coming from Java and PHP. Could someone explain to me why I always have to first allocate and then initialize an instance? Couldn't this be done in the init methods like this: + (MyClass*)init { MyClass *instance = [MyClass alloc]; [instance setFoo:@"bla"]; return instance; } + (MyClass*)initWithString:(NSString*)text { MyClass *instance = [MyClass init]; [instance setFoo:text]; return instance; } ... Is this just a relict from the old C days or is there something that I'm not seeing? I know this isn't a problem as I could as well always call alloc and init, but since it's a bit tedious I'd like to at least know why I'm doing it. I'm liking the expressiveness of the language so far, but this is something that I want to fully understand in order to think the Objective-C way. Thank you!

  • how to convert string to double with proper cultureinfo

    - by Vinay Pandey
    Hi All, I have two nvarchar fields in database to store the DataType and DefaultValue, I have a DataType Double and value as 65.89875 in english format. Now I want the user to see the value as per the selected browser language format (65.89875 in English should be displayed as 65,89875 in german). Now if the user edits from german format to 65,89875 which is 65.89875 equivalent in english, and the other user views from english browser it comes as 6589875. This happens because in DB it was stored as 65,89875 and when converted using english culture it becomes 6589875 since it considers , as seperator. Any Idea how I get this working for all the browsers?
