  • Customizing compare in bsearch()

    - by Richard Smith
    I have an array of addresses that point to integers ( these integers are sorted in ascending order). They have duplicate values. Ex: 1, 2, 2, 3, 3, 3, 3, 4, 4...... I am trying to get hold of all the values that are greater than a certain value(key). Currently trying to implement it using binary search algo - void *bsearch( const void *key, const void *base, size_t num, size_t width, int ( __cdecl *compare ) ( const void *, const void *) ); I am not able to achieve this completely, but for some of them. Would there be any other way to get hold of all the values of the array, with out changing the algorithm I am using?

  • Recursive MySQL function call eats up too much memory and dies.

    - by kylex
    I have the following recursive function which works... up until a point. Then the script asks for more memory once the queries exceed about 100, and when I add more memory, the script typically just dies (I end up with a white screen on my browser). public function returnPArray($parent=0,$depth=0,$orderBy = 'showOrder ASC'){ $query = mysql_query("SELECT *, UNIX_TIMESTAMP(lastDate) AS whenTime FROM these_pages WHERE parent = '".$parent."' AND deleted = 'N' ORDER BY ".$orderBy.""); $rows = mysql_num_rows($query); while($row = mysql_fetch_assoc($query)){ // This uses my class and places the content in an array. MyClass::$_navArray[] = array( 'id' => $row['id'], 'parent' => $row['parent'] ); MyClass::returnPArray($row['id'],($depth+1)); } $i++; } Can anyone help me make this query less resource intensive?

  • Usage of image in sIFR

    Hi there, I want to use sIFR in my blog posts also. But there's a major problem that I couldn't fix. Let's say the blog post is between these divs: <div class="post">BLOG POST IS HERE</div> So, my selector is .post. When I insert an image tag inside this div, the image isn't being showed by the browser. Just like this: <div class="post"><img src="myimage.jpg" align="left" />BLOG POST IS HERE</div> Is there a way to use sIFR with images?

  • Chrome/IE table cell positioning help

    - by Checksum
    I am making a tiny script to make a HTML element editable. When you click on an element, it gets replaced with a textarea, and you can basically enter the new text. When you press enter, the textarea is replaced with the original element with its innerHTML updated. The demo of the script is here: http://iambot.net/demo/editable/ Now the problem is with the inline table editing. It works perfectly on FF 3.6, but on Chrome/Safari, once the value of a cell is updated, the position of the updated cell shifts to the right by the width of a cell.(Just try the demo in Chrome/Safari) It totally messes up the whole table. I am a beginner in CSS and not able to identify where exactly I'm going wrong. Any help/pointers appreciated! Thanks.

  • possible to use <img> as <div>?

    - by FatDogMark
    for example if I want to put an image wrap another object,possible? <img src='pic.png'> <div id='block'> <p>Somebody </div> </img> I know I should just use div and background-image but I want to use the property auto img{width:50%; height:auto;} If I use div , using auto won't works because it won't know the background-image size and will not adjust the div depends on the image ratio aspect.

  • Full background using :cover; makes adds horizontal scroll

    - by user1907341
    I am working on a website which needs a header with full background image & 650 height. At the moment i am using background-size: cover; property with 100% width. While, it's working it leaves an awkward horizontal scroll of about 50px on right side. Which is lot more prominent in smaller resolutions. I tried applying background to body instead of header div too. But same thing happens there as well. You can see a preview here - http://nitingarg.com/projects/tfe/

  • Does the '#' modifier for cropping images in Paperclip work only for square images?

    - by user3451384
    It is very well documented that you can create square thumbnails with center cropping with Paperclip (4) and Rails (4). I would like to have an image of very specific dimensions (e.g. 200x100) and if input an image of let's say 800x200 it is first resized to 400x100 and then the width (400) is cropped down to 200 pixel from the center (i.e. 100px cut from the right and 100 px cut from the left). I tried with 200x100# and it does not appear to work (i.e. the '#' has no effect). I have found that I could adapt other solutions such as this, but I was wondering if '#' is supposed to work only for cropping to square images, or is a Paperclip bug or I am doing something wrong...

  • Problem decrementing in Java with '-='

    - by hanesjw
    I'm making a scrolling game on Android and am having a hard time figuring out why the code below does not decrement past 0. Objects start at the end of the screen (so the x position is equal to the width of the screen) the objects move accross the screen by decrementing their x positions. I want them to scroll off of the screen, but when the x position hits 0, the objects just stay at 0, they do not move into the negatives. Here is my code to move objects on the screen private void incrementPositions(long delta) { float incrementor = (delta / 1000F) * Globals.MAP_SECTION_SPEED; for(Map.Entry<Integer, HashMap<Integer, MapSection>> column : scrollingMap.entrySet()) { for(Map.Entry<Integer, MapSection> row : column.getValue().entrySet()) { MapSection section = row.getValue(); section.x -= incrementor; } } } It works ok if I change section.x -= incrementor; to section.x = section.x - (int)incrementor; but if i do that the scrolling doesn't appear as smooth.

  • Online image resizer

    - by Happy
    Searching for some script or service for online image resizing. I should have the ability to throw my imagelink, like http://site.com/bigimage.jpg, and it must give me this image after resizing like http://site-were-image-resized.com/sdf4234f21f.png. It would be amazing, if I can give some values, like height and width. If I upload script on my own site, it should have the ability to resize external images from some domains. Tryed to use http://www.darrenhoyt.com/demo/timthumb/, but it doesn't work with external images.

  • CSS and JQuery: spaces inside image name break code of url()

    - by Shyam
    Hi, I have a page that is supposed to display a larger version of an image when hovered over a thumbnail. I have a 'div' with an ID and the JQuery code is as following: $(document).ready(function(){ $('img').hover(function() { var src = $("#im" + this.id).attr("src"); $('#viewlarge').css('backgroundImage','url(' + src +')'); return false; }); }); The images I use, are generated by a Ruby script that "generate" an image with a similar, yet different id. However, sometimes, photo's are uploaded that have "spaces" inside. My developer tools tell me that the background-image is not set correctly, yet the image path is correct and the browser don't have problems finding the image. My question is, can I somehow sanitize the url 'src', so spaces won't be a problem? I am aware of doing this server side, yet I would like to know how to do this with JQuery/JS too. Thanks!

  • Writing To The Response in Rails? (Like "echo" in PHP)

    - by Yar
    I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Edit: Here is an example: <% unless @research_activities.size == 0 concat(render(:partial => 'list')) end %> Why would I want to include two closing tags just to do that? It reads nicely in code, doesn't it?

  • How animate stacking divs in javascript/css?

    - by Teiviere
    Say I have 2 divs with the same CSS class that are stacked on top of each other: div { width:100px; height: 100px; background: red; } How do I make it so that when I click a button at the top of the page, a new div is created from off the screen at the bottom and moves upwards stopping where the 2nd div is.. When the button is clicked again, a 4th div moves in from the bottom of the screen and stops where the 3rd div is... etc creating a "stacked" divs effect? I know about position:fixed and adjusting values for top, but I am not sure how to dynamically calculate where to stop the animation to achieve this effect.

  • jQuery plugin to style objects

    - by Alex
    Hi. I've been looking at the various JavaScript UI libraries and am wondering if there's one that can add some styling to page elements. I'm currently adding rounded corners, shadows, borders, and gradients via my own CSS + hacks to get it working on IE. I'm using jQuery for a number of tasks and wondered if there's a plugin that can add these design flairs more easily to DIVs. Not that you want to go overboard with this stuff, but when you need to use it, you'd like to depend on cross-browser and tried-and-tested solutions. Thanks.

  • Can you have 2 completely independent instances of Eclipse running at the same time?

    - by froadie
    I'm sure there isn't really a way to do this, but figured it doesn't hurt to ask... I use Eclipse a lot. I'm currently using it for both Java and Python (with PyDev). I often find that I have one project open, with lots of files, say in Java... And then for some reason I have to switch to a Python project for a bit. I want to leave my Java project the way it is, and I don't just want to open tons of Python files in the same place because then I have too much open at once and get a headache and confused. Is there any way I can just leave the Java project exactly the way it is, and sort of open a completely new session of Eclipse? (sort of the way you can do with a browser) Or is this just wishful thinking?

  • Is there any way around the Chrome 5 breakage of Ajax for local files?

    - by nikow
    The recent Chrome 5.0 release completely blocks XMLHTTPRequest requests for local files comming from a local file. Here is just one of the many related bug reports and here is the code change (there is also a SO question caused by this). This breaks a lot of production code, e.g. for documentation systems. Users must be able to browse local documentation without the need to install anything or run executables. My question is if there is any way around this restriction? I'm only interested in solutions that don't require any fancy actions on the users side (nothing beyond a confirmation dialog). Is there any way the HTML5 File API could be used, or maybe postMessage()? Of course this whole issue is very frustrating for many people. Firefox takes a fare more reasonable approach and allows requests inside the directory. So it seems unlikely that other browser vendors will follow Chrome.

  • require user to login in at login screen before giving access to iPhone app that accesses secure web

    - by MikeN
    On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

  • Find hosted directories Jetty/Apache

    - by Paul Creasey
    Hi, Let say I have a directory which is being hosted by Jetty or Apache (i'd like an answer for both), i know the URL including the port and i can log into the server. How can i find the directory that is being hosted by a certain port? I'd also like to go the other way, i have a folder on the server, which i know if being hosted, but i don't know the port so i can't find it in a web browser. How can i find a list of directories that are being hosted? This has been bugging me for ages but i've never bothered to ask before! Thanks.

  • Associate a URL with a resource within my application

    - by Horace Loeb
    When I visit http://my-application.com/posts/1 in my browser, Rails knows I'm looking for the Post with id = 1. How can I get my application to do this internally? I.e., I'd like a function (call it associate_with_resource) that takes a string containing a URL as its input and outputs the associated resource. For example: >> associate_with_resource('http://my-application.com/posts/1') => #<Post id: 1, ... > (I'd like to be able to use associate_with_resource throughout my application though -- not only in the console)

When I do a print_r($matches), it shows the right results but when I use $matches[1], it browser tells me that there is no such index.

  • Setting language/culture for reporting services report rendered through C#

    - by Chris Latta
    I have written a report renderer in C# that runs and attaches reports to an email. This is all working great, except the date format of the parameters are incorrect when listed in the report title. All the reports have their language set to =User!Language and the parameters are output using the FormatDateTime function to format according to the user's regional settings. I am basically using the rendering method described here on MSDN. This all works great when the reports are run through the browser. However, when I render the report from C# it uses en-US date format. The report server's regional settings are set appropriately to the correct region as are the regional settings of the computer the C# progam is running on.. What property do I need to set in my C# program for the report to be rendered using my appropriate language/culture?
