  • jQuery carousel clicks update <select> list's "selected" option to match clicked item's title attrib

    - by Scott B
    The code below allows me to change a preview image outside the carousel widget so that it matches the element under the mouse. For example, if the user mouses over image2's thumbnail, the script updates .selectedImage so that it displays image2's full size version. I'd like to enhance it so that the #myThumbs options listing updates its "selected" option to match the carousel image that receives a click. Mouseover changes the preview image and click changes the select list to match the same name. The items in the carousel will have the same title attribute as the items in the select list, so I would expect that I can pass that value from the carousel to the select list. $(function() { $("#carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev", visible: 6, mouseWheel: true, speed: 700 }); $('#carousel').show(); $('#carousel ul li').hover(function(e) { var img_src = $(this).children('img').attr('src'); $('.selectedImage img').attr('src',img_src); } ,function() { $('.selectedImage img').attr('src', '<?php echo $selectedThumb; ?>');}); }); <select id="myThumbs"> <option>image1</option> <option selected="selected">image2</option> <option>image3</option> </select>

  • Executing logic before save or validation with EF Code-First Models

    - by Ryan Norbauer
    I'm still getting accustomed to EF Code First, having spent years working with the Ruby ORM, ActiveRecord. ActiveRecord used to have all sorts of callbacks like before_validation and before_save, where it was possible to modify the object before it would be sent off to the data layer. I am wondering if there is an equivalent technique in EF Code First object modeling. I know how to set object members at the time of instantiation, of course, (to set default values and so forth) but sometimes you need to intervene at different moments in the object lifecycle. To use a slightly contrived example, say I have a join table linking Authors and Plays, represented with a corresponding Authoring object: public class Authoring { public int ID { get; set; } [Required] public int Position { get; set; } [Required] public virtual Play Play { get; set; } [Required] public virtual Author Author { get; set; } } where Position represents a zero-indexed ordering of the Authors associated to a given Play. (You might have a single "South Pacific" Play with two authors: a "Rodgers" author with a Position 0 and a "Hammerstein" author with a Position 1.) Let's say I wanted to create a method that, before saving away an Authoring record, it checked to see if there were any existing authors for the Play to which it was associated. If no, it set the Position to 0. If yes, it would find set the Position of the highest value associated with that Play and increment by one. Where would I implement such logic within an EF code first model layer? And, in other cases, what if I wanted to massage data in code before it is checked for validation errors? Basically, I'm looking for an equivalent to the Rails lifecycle hooks mentioned above, or some way to fake it at least. :)

  • Invalid authorization specification error with Classic ASP accessing SQL Server

    - by Scott
    Hi, I am getting the following error: Invalid authorization specification I've narrowed down the error to my connection string. I have verified the server name, database, user & password are correct. Here is the string: "Provider=SQLOLEDB;Server=xxxxx.db.12345.hostedresource.com;Database=foo;UID=fooUser;PWD=fooPW" The SQL server is hosted on Godaddy so I don't have access to its settings. Please help, I've scoured the internet for a solution!

  • JSP template inheritance

    - by Ryan
    Coming from a background in Django, I often use "template inheritance", where multiple templates inherit from a common base. Is there an easy way to do this in JSP? If not, is there an alternative to JSP that does this (besides Django on Jython that is :) base template <html> <body> {% block content %} {% endblock %} </body> <html> basic content {% extends "base template" %} {% block content %} <h1>{{ content.title }} <-- Fills in a variable</h1> {{ content.body }} <-- Fills in another variable {% endblock %} Will render as follows (assuming that conten.title is "Insert Title Here", and content.body is "Insert Body Here") <html> <body> <h1>Insert title Here <-- Fills in a variable</h1> Insert Body Here <-- Fills in another variable </body> <html>

  • How do I specify a project dependency with Hudson?

    - by Brett Ryan
    We have common library projects shared amongst many projects that are required to be checked out into a "Libraries" folder which a developer needs to checkout prior to opening the main project in visual studio. How I tell hudson that there is this dependency? I figured one thing I could do is setup a custom workspace and specify the location for all projects, but how do I wire up the dependency between them all? Is simply specifying "Build after other projects are built" enough?

  • Wordpress Custom Themes > How to script Categories, Tags and Excerpt options to appear on "page" edi

    - by Scott B
    I'm using custom WordPress categories for some probably unintended functions, I will admit (things like marking a post no/index just by adding it to my custom "no-index" category, etc). But it sucks that WordPress does not enable pages with all the little extras you get with posts. For example, while the post editor gives you convenient access to Tags, Categories, and a Post excerpt field, pages get left out in the cold. I'd like to know if its possible to add the These items to the Post editor via add_action() directive from a custom theme.

  • What's the best way to match a query to a set of keywords?

    - by Ryan Detzel
    Pretty much what you would assume Google does. Advertisers come in and big on keywords, lets say "ipod", "ipod nano", "ipod 60GB", "used ipod", etc. Then we have a query, "I want to buy an ipod nano" or "best place to buy used ipods" what kind of algorithms and systems are used to match those queries to the keyword set. I would imagine that some of those keyword sets are huge, 100k keywords made up of one or more actual words. on top of that queries can be 1-n words as well. Any thoughts, links to wikipedia I can start reading? From what I know already I would use some stemmed hash in disk(CDB?) and a bloom filter to check to see if I should even go to disk.

  • How Do I Pass The Value (Not The Reference) of a JS Variable to a Function?

    - by ryan
    Here is a simplified version of something I'm trying to run: for (var i = 0; i < results.length; i++) { marker = results[i]; google.maps.event.addListener(marker, 'click', function() { change_selection(i); }); } but I'm finding that every listener uses the value of results.length (the value when the for loop terminates). How can I add listeners such that each uses the value of i at the time I add it, rather than the reference to i?

  • How do I make a hyperlink to a local executable?

    - by Scott Ferguson
    We have an Intranet website, and a WPF windows executable installed on every workstation. How can we create a hyperlink on the intranet website that will launch the locally installed executable? Ideally we want the launch to be seamless. Is there a way of setting the browsers trust settings so that it won't display a security warning dialog for this executable? We have full admin capabilities on each workstation, and each user only uses Internet Explorer. We also know the correct local path for the exe.

  • PHP Regex: How to match anything except a pattern between two tags

    - by Ryan
    Hello, I am attempting to match a string which is composed of HTML. Basically it is an image gallery so there is a lot of similarity in the string. There are a lot of <dl> tags in the string, but I am looking to match the last <dl>(.?)+</dl> combo that comes before a </div>. The way I've devised to do this is to make sure that there aren't any <dl's inside the <dl></dl> combo I'm matching. I don't care what else is there, including other tags and line breaks. I decided I had to do it with regular expressions because I can't predict how long this substring will be or anything that's inside it. Here is my current regex that only returns me an array with two NULL indicies: preg_match_all('/<dl((?!<dl).)+<\/dl>(?=<\/div>)/', $foo, $bar) As you can see I use negative lookahead to try and see if there is another <dl> within this one. I've also tried negative lookbehind here with the same results. I've also tried using +? instead of just + to no avail. Keep in mind that there's no pattern <dl><dl></dl> or anything, but that my regex is either matching the first <dl> and the last </dl> or nothing at all. Now I realize . won't match line breaks but I've tried anything I could imagine there and it still either provides me with the NULL indicies or nearly the whole string (from the very first occurance of <dl to </dl></div>, which includes several other occurances of <dl>, exactly what I didn't want). I honestly don't know what I'm doing incorrectly. Thanks for your help! I've spent over an hour just trying to straighten out this one problem and it's about driven me to pulling my hair out.

  • How can I manually interpolate string escapes in a Perl string?

    - by Ryan Thompson
    In perl suppose I have a string like 'hello\tworld\n', and what I want is: 'hello world ' That is, "hello", then a literal tab character, then "world", then a literal newline. Or equivalently, "hello\tworld\n" (note the double quotes). In other words, is there a function for taking a string with escape sequences and returning an equivalent string with all the escape sequences interpolated?

  • Understanding The Convolution Matrix

    - by Ryan Naddy
    I am learning about the Convolution Matrix, and I understand how they work, but I don't understand how to know before hand what the output of a Matrix will look like. For example lets say I want to add a blur to an image, I could guess 10,000+ different combinations of numbers before I get the correct one. I do know though that this formula will give me a blur effect, but I have no idea why. float[] sharpen = new float[] { 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f, 1/9f }; Can anyone either explain to me how this works or point me to some article, that explains this? I would like to know before hand what a possible output of the matrix will be without guessing. Basically I would like to know why do we put that number in the filed, and why not some other number?

  • RSA Encryption C#

    - by Ryan
    Hi guys, I have a class which in C# doing RSA encryption where I used the default RSACryptoServiceProvider class. But I have a concern regarding the following; If you have the word hello for an input and the encrypted string is returned as ABCDE, if you perform another encrypt operation on the input hello, using the same keys (public and private) for the RSA will the output be again ABCDE? Thanks in advance

  • Perl ftp question, like the previous ones ...

    - by Jerry Scott
    I need to move or copy a simple text file from one web site to another web site. I have administrator rights to both web sites. The first web site has a large data file (again, just a text file), certain records are selected and written to a team file (for entry into a tournament). Next I go through paypal and pay for the entries. The second site is for the the club running the tournament and I use IPN to return to a script on their site and if it verified, I add the team memebers into the master file for the tournament. I am limited to the ONE IPN script on the tournament site because I have a ton of other entries that come in from all over. The first site has the rosters for the state and no need to type all that data from each club, use the rosters like I use for all the non-paypal tounamenmts. I can ftp the team file to the second server and place it in the folder just like it was created from scratch from that server originally and everything should go fine but I took the examples and tried them and nothing. Here's the code section: my $custom = $in->param('custom'); my $filename = "$ENV{DOCUMENT_ROOT}/database/$custom"; my $usjochost = '208.109.14.105'; my $okserieshost = '208.109.181.196'; my $usjocuser = 'teamentry'; my $okseriesuser = 'okwaentry'; my $usjocpw = 'Password1'; my $okseriespw = 'Password1'; my $file = $custom; my $usjocpath ='/home/content/u/s/j/usjoc/html/database/'; my $okseriespath ='/home/content/o/k/s/okseries/html/database/'; $ftp = Net::FTP->new($okserieshost, Debug => 0) or die "Could not connect to '$okserieshost': $@"; $ftp->login($okseriesuser, $okseriespw) or die sprintf "Could not login: %s", $ftp->message; #$ftp->cwd(/database) or die sprintf "Could not login: %s", $ftp->message; $ftp->get($filename); #$ftp = Net::FTP->new($usjochost, Debug => 0) or die "Could not connect to '$usjochost': $@"; $ftp->quit; I NEED to READ the file on the first web site (okseries.com) and write the file on the second web site (usjoc.com). I have no problem reading and writing the file on the server, is sending the file to the second server. HELP! I'm not a genius at PERL.

  • Is there a way to write System.Drawing.Graphics to PDF from C#?

    - by Brett Ryan
    I have a whole bunch of 2D graphics that is being used for both rendering controls on screen and used to print, it's pretty custom graphics that couldn't be done by any 3rd party reporting tools or off the shelf controls. The program can generate PDF files of the printed content but when I wrote it I cheated and just print the Graphics object to an in memory image and then embed that into the PDF page. Since the users are emailing the documents they're finding they are too large. I've started writing the PDF from scratch using iText, however is there a way to get System.Drawing.Graphics content directly into PDF? The way iText works and Graphics works is completely different.
