  • Button with image and loading element id when clicked

    - by Diego Correa
    Hello guys, I've made an application that makes full use of ajax, and what I need to do is: I want a button with a description + image that when clicked is disabled and instead of the original image in the button, appears the ajax loading element id inside the button. And when the ajax loading is complete, the original image of the button returns to the normal. Is there any good source on how to do something like this? What do you guys suggest?

  • WCF service for receiving image

    - by elgrego
    What is the best way to create a webservice for accepting an image. The image might be quite big and I do not want to change the default receive size for the web application. I have written one that accepts a binary image but that I feel that there has to be a better alternative.

  • Interpreting Search Results

    - by Simon
    Hi all, I am tasked with writing a program that, given a search term and the HTML source of a page representing search results of some unknown search engine (it can really be anything, a blog, a shop, Google, eBay, ...), needs to build a data structure of the results containing "what's in the results": a title for earch result, the "details" link, the position within the results etc. It is not known whether the results page contains any of the data at all, and whether there are any search results. The goal is to feed the data structure into another program that extracts meaning. What I am looking for is not BeautifulSoup or a RegExp but rather some clever ideas or algorithms on how to interpret the HTML source. What do I do to find out what part of the page constitutes a single result item? How do I filter the markup noise to extract the important bits? What would you do? Pointers to fields of research covering what I try to to are aly greatly appreciated. Thanks, Simon

  • Generating MySQL UPDATE statements containing BLOB image data

    - by Bob
    I'm trying to write an SQL statement that will generate an SQL script that will update a BLOB field with an IMAGE being selected from the database. This is what I have: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = ', QUOTE( THUMBNAIL ), ' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; In the above, THUMBNAIL is a BLOB field containing raw image data. When I run the resulting script I get the following error: ERROR at line 2: Unknown command '\\'. I first tried this without the QUOTE() function, like so: select concat( 'UPDATE `IMAGE` SET THUMBNAIL = \'', THUMBNAIL, '\' WHERE ID = ', ID, ';' ) as UPDATE_STATEMENT from IMAGE; Running the resulting script produces this error: ERROR at line 2: Unknown command '\0'. What is the proper function to apply to this BLOB field in the select, so the UPDATE statements will work? If context is required, I'm looking to migrate thumbnails generated on one server to another server for certain image IDs only. I would use mysqldump, but I don't want to clobber the entire table. Any help is greatly appreciated!

  • ASP.NET MVC Paging for a search form

    - by James Alexander
    I've read several different posts on paging w/ in MVC but none describe a scenario where I have something like a search form and then want to display the results of the search criteria (with paging) beneath the form once the user clicks submit. My problem is that, the paging solution I'm using will create <a href="..."> links that will pass the desired page like so: http://mysite.com/search/2/ and while that's all fine and dandy, I don't have the results of the query being sent to the db in memory or anything so I need to query the DB again. If the results are handled by the POST controller action for /Search and the first page of the data is rendered as such, how do I get the same results (based on the form criteria specified by the user) when the user clicks to move to page 2? Some javascript voodoo? Leverage Session State? Make my GET controller action have the same variables expected by the search criteria (but optional), when the GET action is called, instantiate a FormCollection instance, populate it and pass it to the POST action method (there-by satisfying DRY)? Can someone point me in the right direction for this scenario or provide examples that have been implemented in the past? Thanks!

  • Theming the default search results page in Drupal

    - by David Pratt
    I'm trying to customise the mark-up of the default search results page in Drupal 6. Specifically I'd like to remove the search box and the title from the page - I know I can hide it with CSS, but I'd rather it wasn't rendered in the first place. Ideally, in the same why that you theme a particular content type node by copying the node.tpl.php and renaming it to something like node-blog.tpl.php and then amending the mark-up accordingly - is there an equivalent way to do this for the search results page?

  • jquery background image rotating script doesn't work

    - by Catfish
    I'm writing this script to rotate a background Image every 3 seconds but it doesn't work at all and i'm stumped as to why not. $(document).ready(function() { var inc = 0; var bgImages = new Array(); bgImages.push("../Images/backgroundDog-small.jpg"); bgImages.push("../Images/backgroundDog1-small.jpg"); bgImages.push("../Images/backgroundDog2-small.jpg"); bgImages.push("../Images/backgroundDog3-small.jpg"); setInterval(change, 3000); function change() { //if we're not at the end of the array if (inc < (bgImages.length)) { var image = bgImages[inc]; $('body').css('backgroundImage', image); console.log(image); inc++; //reset the counter inc and go through the array again } else { inc = 0; } } });

    I would like to run the Windows Desktop Search indexer at below normal priority. When I try to set this via task manager, I get 'Access is denied'. Is there a way to remove whatever restrictions are protecting this process? Or ideally, configure it to have the lower priority on startup? XPSP3 btw.

  • How do I use a ListProperty(users.user) in a djangoforms.ModelForm on Google AppEngine?

    - by Gabriel
    I have been looking around a bit for info on how to do this. Essentially I have a Model: class SharableUserAsset(db.Model): name = StringProperty() users = ListProperty(users.User) My questions are: What is the best way to associate users to this value where they are not authenticated, visa vi invite from contacts list etc.? Is there a reasonable way to present a list control easily in a djangoforms.ModelForm? Once a user logs in I want to be able to check if that user is in the list for any number of SharableUserAsset class "records", how do I do that? Does user evaluate as a match to an email address or is there a way to look up a valid user against an email address?

  • Image through Script, How to add variable to URL

    - by Liso22
    I'm sure it's pretty straightforward since someone just solved a similar problem I had. I have a folder full of city images and need users to see the image corresponding to their city. Right now I'm getting the users location without problem using "geoip_city()" but I don't quite know how to integrate it into the URL of the image. All images have the following format: New York.jpg, Boston.jpg so I just need to make the script put the location before .jpg This is what I'm trying now: <img src="blank.png" id="image" > <script type="text/javascript"> document.getElementById('image').src = "Imagenes/grupos/' + geoip_city() + '.jpg"; </script> I believe I'm just messing with the quotes or something similar. Could anyone tell me what I'm doing wrong? Also this is where I'm testing it: http://chusmix.com/?page_id=1770 Thanks

  • Processing image data in java me

    - by Trimack
    Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  • How to do a search from a list with non-prefix keywords

    - by aNui
    First of all, sorry if my english or my post got any mistakes. I am programming a program to search the name from the list and I need to find them if the keyword is not in front of the names (that's what I mean non-prefix) e.g. if I my list is the music instruments and I type "guit" to the search textbox. It should find the names "Guitar, Guitarrón, Acoustic Guitar, Bass Guitar, ..." or something like this Longdo Dictionary's search suggestion. here is my simple and stupid algorithm (that's all I can do) const int SEARCHROWLIMIT = 30; private string[] DoSearch(string Input, string[] ListToSearch) { List<string> FoundNames = new List<string>(); int max = 0; bool over = false; for (int k = 0; !over; k++) { foreach (string item in ListToSearch) { max = (max > item.Length) ? max : item.Length; if (k > item.Length) continue; if (k >= max) { over = true; break; } if (!Input.Equals("Search") && item.Substring(k, item.Length - k).StartsWith(Input, StringComparison.OrdinalIgnoreCase)) { bool exist = false; int i = 0; while (!exist && i < FoundNames.Count) { if (item.Equals(FoundNames[i])) { exist = true; break; } i++; } if (!exist && FoundNames.Count < SEARCHROWLIMIT) FoundNames.Add(item); else if (FoundNames.Count >= SEARCHROWLIMIT) over = true; } } } return FoundNames.ToArray(); } I think this algorithm is too slow for a large number of names and after several trial-and-error, I decided to add SEARCHROWLIMIT to breaks the operation And I also think there're some readymade methods that can do that. And another problem is I need to search music instruments by a category like strings, percussions, ... and by the country of origins. So I need to search them with filter by type and country. please help me. P.S. Me and my friends are just student from Thailand and developing the project to compete in Microsoft Imagine Cup 2010 and please become fan on our facebook page [KRATIB][3]. And we're so sorry we don't have much information in English but you can talk to us in English.

  • PIL's Image.show() brings up *two* different viewers

    - by DarenW
    When toying with images in the python shell, I use image.show(), where image is an instance of Image. Long ago nothing happened, but after defining a symlink to mirage named "xv", I was happy. The last few days, show() will bring up both ImageMagick's display and also Mirage. It's not clear where show() gets information on what to run. Documentation wasn't helpful. How to make it behave and bring up only what it thinks is xv?

  • Google app engine - what is the lifecycle of PersistenceManager?

    - by Domchi
    What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

  • Creating search functionality with Laravel 4

    - by Mitch Glenn
    I am trying to create a way for users to search through all the products on a website. When they search for "burton snowboards", I only want the snowboards with the brand burton to appear in the results. But if they searched only "burton", then all products with the brand burton should appear. This is what I have attempted to write but isn't working for multiple reasons. Controller: public function search(){ $input = Input::all(); $v= Validator::make($input, Product::$rules); if($v->passes()) { $searchTerms = explode(' ', $input); $searchTermBits = array(); foreach ($searchTerms as $term) { $term = trim($term); if (!empty($term)){ $searchTermBits[] = "search LIKE '%$term%'"; } } $result = DB::table('products') ->select('*') ->whereRaw(". implode(' AND ', $searchTermBits) . ") ->get(); return View::make('layouts/search', compact('result')); } return Redirect::route('/'); } I am trying to recreate the first solution given for this stackoverflow.com problem The first problem I have identified is that i'm trying to explode the $input, but it's already an array. So i'm not sure how to go about fixing that. And the way I have written the ->whereRaw(". implode(' AND ', $searchTermBits) . "), i'm sure isn't correct. I'm not sure how to fix these problems though, any insights or solutions will be greatly appreciated.

  • Storing an image map in a database

    - by ColoradoRockie
    I have a requirement to allow users in a content management system to create their own image maps through a gui interface, which I have accomplished. But instead of saving the image map to the page code, I want to save the image map code to a database (sql), which I've also accomplished. When I started down this road in my head I was thinking the whole time that I'd just add the "usemap" attribute at runtime shown below where promo1.ImageMap holds the entire map code: if(promo1.HasImageMap) imgPromotion1.Attributes.Add("usemap", promo1.ImageMap); I guess I didn't think it though well enough, because it seems that "usemap" only expects the name of the existing map to use from the page code, and not the map code as a string. Does anyone have any clever ideas on how to apply the map from the database to the image at run time?
