  • jQueryUI Slider handle not moving

    - by DavidYell
    I'm trying to implement a jQuery slider with increments. I've gone from, the actual project page, to a test page of the project with just the slider, to just the slider. In all cases I've been unable to get the handle to move. It also seems to have a width of 1px or similar. My code is as follows, <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <title>jQuery slider</title> <link rel="stylesheet" href="css/ui-lightness/jquery-ui-1.8.custom.css" type="text/css" media="screen" charset="utf-8" /> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="js/jquery-ui-1.8.custom.min.js"></script> <script type="text/javascript"> $(function() { $("#slider").slider(); }); </script> </head> <body> <div id="slider"></div> </body> </html> I'm sure there is something very simple at fault here, but I really cannot see it for the life of me. The custom part of my download, was just clicking the 'select all components'.

  • Why doesn't this (translated) VB.NET code work?

  • PHP check if file exists on my server, based on a full URL

    - by stef
    I have an app that generates invoices in the form of PDF files stored in a directory on my server. Before mailing out this invoices I'd like to make sure that the URL (not server path) which I store in my DB does indeed point to a valid PDF file. Something could have gone wrong that wrote a value to that field in the db, but for example the filename is missing; meaning the file is not in the specified directory. AFAIK file_exists just checks server paths but not URL's. I could always store the server path too, or assemble it, but I'm wondering if i can do this check based on a full http url ending with a filename? EDIT: yeah CURL occurred to me too but doesn't that seem a bit heavy for such a simple task? Perhaps I should just store the server path too.

  • Why exactly is eval evil?

    - by Jay
    I know that Lisp and Scheme programmers usually say that eval should be avoided unless strictly necessary. I´ve seen the same recommendation for several programming languages, but I´ve not yet seen a list of clear arguments against the use of eval. Where can I find an account of the potential problems of using eval? For example, I know the problems of GOTO in procedural programming (makes programs unreadable and hard to maintain, makes security problems hard to find, etc), but I´ve never seen the arguments against eval. Interestingly, the same arguments against GOTO should be valid against continuations, but I see that Shemers, for example, won´t say that continuations are "evil" -- you should just be careful when using them. They´re much more likely to frown upon code using eval than upon code using continuations (as far as I can see -- I could be wrong).

  • PHP: How To Integrate HTML Purifier To Fileter User Submitted Data?

    - by TaG
    I have this script that collects data from users and I wanted to check their data for malicious code like XSS and SQL injections by using HTML Purifier http://htmlpurifier.org/ but how do I add it to my php form submission script? Here is my HTML purifier code require_once '../../htmlpurifier/library/HTMLPurifier.auto.php'; $config = HTMLPurifier_Config::createDefault(); $config->set('Core.Encoding', 'UTF-8'); // replace with your encoding $config->set('HTML.Doctype', 'XHTML 1.0 Strict'); // replace with your doctype $purifier = new HTMLPurifier($config); $clean_html = $purifier->purify($dirty_html); Here is my PHP form submission code. if (isset($_POST['submitted'])) { // Handle the form. $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"SELECT users.*, profile.* FROM users INNER JOIN contact_info ON contact_info.user_id = users.user_id WHERE users.user_id=3"); $about_me = mysqli_real_escape_string($mysqli, $_POST['about_me']); $interests = mysqli_real_escape_string($mysqli, $_POST['interests']); if (mysqli_num_rows($dbc) == 0) { $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"INSERT INTO profile (user_id, about_me, interests) VALUES ('$user_id', '$about_me', '$interests')"); } if ($dbc == TRUE) { $dbc = mysqli_query($mysqli,"UPDATE profile SET about_me = '$about_me', interests = '$interests' WHERE user_id = '$user_id'"); echo '<p class="changes-saved">Your changes have been saved!</p>'; } if (!$dbc) { // There was an error...do something about it here... print mysqli_error($mysqli); return; } }

  • When is referential integrity not appropriate?

    - by Curtis Inderwiesche
    I understand the need to have referential integrity for limiting specific values on entry or possibly preventing them from removal upon a request of deletion. However, I am unclear as to a valid use case which would exclude this mechanism from always being used. I guess this would fall into several sub-questions: When is referential integrity not appropriate? Is it appropriate to have fields containing multiple and/or possibly incomplete subsets of a foreign key's list? Typically, should this be a schema structure design decision or an interface design decision? (Or possibly neither or both) Thoughts?

  • Returning in a static initializer

    - by Martijn Courteaux
    Hello, This isn't valid code: public class MyClass { private static boolean yesNo = false; static { if (yesNo) { System.out.println("Yes"); return; // The return statement is the problem } System.exit(0); } } This is a stupid example, but in a static class constructor we can't return;. Why? Are there good reasons for this? Does someone know something more about this? So the reason why I should do return is to end constructing there. Thanks

  • asp.net compare validators to allow comma and dot (both!) as decimal separator

    - by DanC
    I am using a compare validator, which validates that the entered number is a valid double and also validates it against a given value (greater than zero). I am validating money amounts. Because of the location where the app is used, the locale sets the comma as the decimal separator. The problem is that when a user enters the value using the numeric keyboard, the number gets written with the dot as decimal separator, and is rejected by the validation. I'd like to have this validation done before triggering a postback (like a customvalidator would) and accepting both separators. Any ideas? Thanks

  • Expression Encoder SDK - WMA Pro Codec Issues with Windows Server 2003

    - by PortageMonkey
    I am using the Expression Encoder SDK to encode .avi and Flash files to a .wmv format suitable for Silverlight. By default, EE encodes files with audio using the the WMA PRO codec. If you are running Windows Server 2003, this is a problem as it doesn't support the WMA PRO codec and produces and error message similar to the following. Error Message: The Audio Profile settings do not match a valid system profile. Error Source: Microsoft.Expression.Encoder Error Target Site: System.String GetProfileString() I am looking for a way to change the default audio codec to something suitable for WS 2003. I am aware that although not supported natively, there is a highly invasive way to install Windows Media Player 11 and it's codecs on WS 2003 but this involves registry tinkering and other hacks not suitable for our production environments so that solution is out.

  • Is it possible to inject a bean into a spring form bean

    - by Mike
    I tried to do it 2 different ways, but neither way worked. @Component public class EmailForm{ ... private QuestionDAO questionDAO; ... @Autowired public void setQuestionDAO(QuestionDAO questionDAO) { this.questionDAO = questionDAO; } ... Another way: @Component public class EmailForm implements ApplicationContextAware { ... public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { this.questionDAO = (QuestionDAO)applicationContext.getBean("questionDAO"); } ... Neither way results in questionDAO being injected Form bean is populated by spring: @RequestMapping(method = RequestMethod.POST) public String submit(@Valid final EmailForm emailForm, BindingResult result, final Model model) {

  • Exclude all normal alphanumeric character from a mixed chinese-and-alphanumeric character word list

    - by Christine
    I have a list of chinese characters and normal alphanumeric characters, mixed together, and I want to get rid of any element that contains an alphanumeric character. Is there a simple way to do this? If I simply exclude any element that contains an alphanumeric character, I get no result because the chinese characters (in utf-8) are similarly affected. I also tried [w for w in fourchar if w.startswith("\x")] to try to get the chinese characters but I'm not sure if that's valid at all. I'm having difficulty figuring out what the alphanumeric characters are in unicode. Thanks for any help!

  • Authenticating a Server with Digital Signatures

    - by TomS
    I understand how Non-repudiation and Integrity are achieved with Digital Signatures, but it's the Authentication that I don't grasp yet. I'm developing a Client-Server application in C#, that should be capable of Authentication with Digital Certificates and Digital Signatures. I know how to check the validity and integrity of a Signature (with SignedCms.CheckSignature()), but how does this authenticates any of the parts involved? For example: The client asks the Server for a Digital Signature, The client receives the signature and validates it, If the validation succeeds, continue. The client could be a victim of a man-in-the middle attack and receive a valid signature in step 2. The validation would succeed, but the client wouldn't be talking to the right server. What am I missing?

  • How to validate two properties with ASP.NET MVC 2

    - by CodeMonkey
    Hey folks :-) I'm just getting started with ASP.NET MVC 2, and playing around with Validation. Let's say I have 2 properties: Password1 Password2 And I want to require that they are both filled in, and require that both are the same before the model is valid. I have a simple class called "NewUser". How would I implement that? I've read about ValidationAttribute, and understand that. But I don't see how I would use that to implement a validation that compares two or more properties against eathother. Thanks in advance!

  • Does C99 guarantee that arrays are contiguous ?

    - by kriss
    Following an hot comment thread in another question, I came to debate of what is and what is not defined in C99 standard about C arrays. Basically when I define a 2D array like int a[5][5], does the standard C99 garantee or not that it will be a contiguous block of ints, can I cast it to (int *)a and be sure I will have a valid 1D array of 25 ints. As I understand the standard the above property is implicit in the sizeof definition and in pointer arithmetic, but others seems to disagree and says casting to (int*) the above structure give an undefined behavior (even if they agree that all existing implementations actually allocate contiguous values). More specifically, if we think an implementation that would instrument arrays to check array boundaries for all dimensions and return some kind of error when accessing 1D array, or does not give correct access to elements above 1st row. Could such implementation be standard compilant ? And in this case what parts of the C99 standard are relevant.

  • Git push origin master

Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

  • Completely bizarre Firefox CSS bug

    - by Jason
    I've been doing front end development for a long time, and I have NEVER come across a bug like this before... Save the following HTML to a file and view it in Firefox (mine is 3.6.3): <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { font-family: Helvetica, Sans-Serif;} h2 {font-weight: normal;} </style> </head> <body> <h2>Some normal text <strong>some bold text</strong> weird huh?</h2> </body> </html> If you don't want to give it a shot the output is like your cat walked across your keyboard while character map was turned on, except in the strong tags. I feel like this may be a font issue? When I get rid of font-weight: normal it goes back to normal, but I don't want everything to be bolded in my h2... Anyone have any ideas? More importantly, is anyone able to reproduce this?? Thanks.

  • Deletion procedure for a Binary Search Tree

    - by Metz
    Consider the deletion procedure on a BST, when the node to delete has two children. Let's say i always replace it with the node holding the minimum key in its right subtree. The question is: is this procedure commutative? That is, deleting x and then y has the same result than deleting first y and then x? I think the answer is no, but i can't find a counterexample, nor figure out any valid reasoning. EDIT: Maybe i've got to be clearer. Consider the transplant(node x, node y) procedure: it replace x with y (and its subtree). So, if i want to delete a node (say x) which has two children i replace it with the node holding the minimum key in its right subtree: y = minimum(x.right) transplant(y, y.right) // extracts the minimum (it doesn't have left child) y.right = x.right y.left = x.left transplant(x,y) The question was how to prove the procedure above is not commutative.

  • IPv6 parsing in C

    - by The Stig
    I wanted to know how i can parse an IPv6 address in 'C' and convert it to a 128 bit value? So a hex address like 1:22:333:aaaa:b:c:d:e:f needs to be converted to its 128 bit equivalent binary. The problem is the IP address could be of the type ::2 and its variant since they are valid IPv6 address. The input is from the keyboard and hence is in ASCII format. Any suggestions or pointers will be appreciated. Thanks!!!

  • Creating method templates in Eclipse

    Is there any way to do the following in eclipse? Have eclipse template a method like the following public void test(){ // CREATE MOCKS // CREATE EXPECTATIONS // REPLAY MOCKS // VERIFY MOCKS } so then I could presumably just use intellisense and select an option like "createtest" and have it stub out a method with the comments similar to the above?My problem is that often myself and other developers I know forgot all the steps we need to follow to do what we dub as a valid unit test for our application. If I could template our test methods to stub out the comments above it would be a big help.

  • How to assign default values and define unique keys in Entity Framework 4 Designer

    - by csharpnoob
    Hello, I've had a look at the Entity Framework 4. While generating code for the SQL Server 2008 I came to the point where I want to define some default values for some fields. how to define in the designer for a Created DateTime Field the DateTime.Now default value? - Error 54: Default value (DateTime.Now) is not valid for DateTime. The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ' how to make for code generation a string Field unique. Like E-Mail or Username can exists only once in the table. I've search alot in the internet and also checked my books Pro Entity Framework 4.0 and Programming Entity Framework. But none of them seems to come up with the default value issue, or using sql commands as default values for database generation. Another thing is, how to prevent on database generation always from droping tables? Instead i want to append non existing fields and keep the data. Thanks for any suggestions.
