  • why does $.ajax(..) not work for me?

    - by dr jerry
    I'm running jquery from a file. And I'm trying to load a svg file from my localhost to populate a svg canvas. However that does not work as expected. What I do from filesystem: $.ajax({ url: url , timeout: 1000, complete: function(xml) { alert('complete'); }, success: function(xml, status, xreq) { alert('success'); }, error: function() { alert('error'); } }); the url reads: http://localhost/image.svg, when I read this url directly from an addressbar from the browser, the pages remains white but the pagesource displays the source of image.svg. Debugging the $.ajax code above, reveals that the success: method is hit, but xml response remains empty. Any help is greatly appreciated. regards, jeroen.

  • build a chrome extension in order to upload images (from clipboard)

    - by dayscott
    I wanted to write a simple chrome extension in order to substitute the following sequence of steps which i have to do very often for university: make screenshot of something edit screenshot in Paint save unnamend.png to harddrive upload unnamed.png to imageshack.us/pic-upload.de or any other website share link of image with others. I don't care which image upload service to use, i just want automize this use-case in order to save time (I already red and did a getting-started chrome extension and checked out their API, but that's it, this page: http://farter.users.sourceforge.net/blog/2010/11/20/accessing-operating-system-clipboard-in-chromium-chrome-extensions/ seemed useful, but i couldn't make it overwrite my systems clipboard - moreover i can't find a tutorial which helps me further).

  • Hiding Text in ie7

    - by user356849
    So I have this text generated by a javascript plugin. <a class="className">Text</a> a.className { background: url(images/a-image.png) no-repeat; } But the "Text" shows on top of the image... Now... with any respectable web browser, I can use color: rgba(0,0,0,0); to solve the problem, but IE7 doesn't obey standards of any sort. Any ideas?

  • What is the standard way to add an icon to a link with CSS?

    - by ewernli
    I'm used to use padding + background-image to place an icon next to a link. There are many example of this approach. Here is one from here: <a class="external" href="http://www.othersite.com/">link</a> a.external { padding-right: 15px; background: transparent url(images/external-link-icon.gif) no-repeat top right; } But most browser don't print background image, which is annoying. What is the standard to place icon next to links which is semantically correct and works in all cases? (I couldn't find an exact similar question. If there is one, just close this one as duplicate)

  • Webserver for publishing adjusted images

    - by Petr Prikryl
    I want to create webserver which will be receiving data (images probably) from webclients who will be uploading these photos. And then the webserver must execute some graphic programs (client select whichone) to modify the image(s). After the graphic program is done, the results (output image(s)) will be uploaded to the web temp database (by webserver) to publish results of graphic programs. I found the C++ web toolkit (http://www.webtoolkit.eu), but I'm not sure if this is a suitable C/C++ library for me because I haven't any experiences with making C/C++ web apps/servers. Can someone tell me some advice please? The webserver should have some SDK too, for adding next graphic programs. I'm searching only for any C/C++ tools/libraries/etc.

  • Searching pgadmin db and grabbing information?

    - by Bootstrotter
    I'm currently trying to write a script in RoR to go into my PGAdmin database and look at a list of users, THEN ignore users that have an image path but look at users who don't have one and then upload a link of a generic photo into their row. My database looks Something like this: id integer | name | email | image path | 12 Bob [email protected] www.faces.org 81 Sally [email protected] 114 Mark [email protected] www.faces.org How would I start grabbing those users, I only have 103 users right now, but I also need to think about scaling for the future. Here is a starting point. I know this is kind of vague but really all I need is just a starting point. to get into it. Thanks for the information. require 'sqlite3' db = SQlite3 users = users.find([1, 103]) Any help would be great.

  • Creating huge images

    - by David Rutten
    My program has the feature to export a hi-res image of the working canvas to the disk. Users will frequently try to export images of about 20,000 x 10,000 pixels @ 32bpp which equals about 800MB. Add that to the serious memory consumption already going on in your average 3D CAD program and you'll pretty much guarantee an out-of-memory crash on 32-bit platforms. So now I'm exporting tiles of 1000x1000 pixels which the user has to stitch together afterwards in a pixel editor. Is there a way I can solve this problem without the user doing any work? I figured I could probably write a small exe that gets command-lined into the process and performs the stitching automatically. It would be a separate process and it would thus have 2GB of ram all to itself. Or is there a better way still? I'd like to support jpg, png and bmp so writing the image as a bytestream to the disk is not really possible.

  • jQuery action being called when selector isn't met?

    - by dougoftheabaci
    I've been working on a prototype for a client's web site and I've run into a rather significant snag. You can view the prototype here. As you can see, the way it works is you can scroll a set of slides horizontally and, by clicking one, open a stack containing yet more slides. If you then click again on an image in that stack it opens up a lightbox. Clicking on another stack or the close button will close that stack (and open another, as case may be). That all works great. However you get some weird behavior if you do the following: Click to open any stack. Click to open an image's light box (this works best if you click on the image that's level with the main list). Close the light box and the stack either by clicking the close button or clicking on another stack. Click back to the first stack. Instead of reopening the stack, you get the lightbox. This confuses me as the light box should only ever be called if there is a class on the containing UL and that class is removed when the lightbox is closed. I've checked and double-checked this, it's definitely missing. Here are the respective functions: $("ul.hide a.lightbox").live("click",function(){ $("ul.show").removeClass("show").addClass("hide"); $(this).parent().parent().removeClass("hide").addClass("show"); $("ul.hide").animate({opacity: 0.2}); $("ul.show").animate({opacity: 1}); $("#next").animate({opacity: 0.2}); $("#prev").animate({opacity: 0.2}); return false; }); $("ul.show a.lightbox").live("click",function(){ $(this).fancybox().trigger("click"); return false; }); As you can see, in order for the lightbox to be called the containing UL has to have the class of show. However, if you check it with Firebug it won't. For those who are curious, the added .trigger("click"); is because the lightbox will require a double-click to launch otherwise. Any idea how I can fix this?

  • Bug? Flash of white when changing orientation on iOS Safari [migrated]

    - by Baumr
    What causes the flash of white to the right of a responsive design when changing orientation from portrait to landscape on iOS? Try it on iOS6 Safari: Websites like this don't do it: http://html5boilerplate.com But this one does: http://www.initializr.com Something to do with re-processing (CPU lag) to fit a wider screen? It doesn't happen in Chrome for iOS6... Update: I just removed all img and from my testing site, but it still happens. This seems to happen with a lot of different websites out there. Is it a bug with their code, or a Safari for iOS bug? Others are completely immune to it...

  • Ruby: if statement using regexp and boolean operator [migrated]

    - by bev
    I'm learning Ruby and have failed to make a compound 'if' statement work. Here's my code (hopefully self explanatory) commentline = Regexp.new('^;;') blankline = Regexp.new('^(\s*)$') if (line !~ commentline || line !~ blankline) puts line end the variable 'line' is gotten from reading the following file: ;; alias filename backupDir Prog_i Prog_i.rb ./store Prog_ii Prog_ii.rb ./store This fails and I'm not sure why. Basically I want the comment lines and blank lines to be ignored during the processing of the lines in the file. Thanks for your help.

  • Tell the CDI 2 Expert Group What You Think!

    - by reza_rahman
    Since it's introduction in Java EE 6, CDI has become a key API for the platform. CDI 1.1 was a relatively minor release included in Java EE 7 as was CDI 1.2 (to be included in GlassFish 4.0.1). We have much higher expectations from CDI 2 (projected to be included in Java EE 8) under the new leadership of Antoine Sabot-Durand. Much like we conducted the Java EE 8 survey to solidify future direction for the platform, CDI 2 is now undergoing the same effort. Towards this goal the CDI 2 leadership is now soliciting feedback on some very specific items via an open survey. Topics include the likes of Java SE bootstrap, asynchronous processing, modularity, EJB-style @Startup and @Asynchronous in CDI, configuration and CDI Lite. You can of course also provide free-form input on anything that's not on the survey. Take the survey now on the CDI specification site and help shape the future of CDI 2 and Java EE 8!

  • iOS iPad Master Detail template can't interact with detail view

    - by CraigularB
    I have an iPad app generated from the Master-Detail template in XCode. The iPad Storyboard has under the Detail View Controller a View that holds a ScrollView which holds an ImageView. In the DetailViewController.m file I added the following code to allow the ScrollView to move and zoom the image: -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.comicImage; } This works great on the iPhone (it's a universal app) but not the iPad; I can scroll and zoom the image on the iPhone no problem, but on the iPad it's like the ScrollView isn't responding to the touches, and I can't figure out how to pass the touches on to the ScrollView. I've already deactivated the popover controller from appearing with a right swipe like this: self.splitViewController.presentsWithGesture = NO; How do I make it so the user can interact with the ScrollView in the DetailViewController?

  • Dynamic Components

    - by Alex
    I am attempting to design a component-based architecture that allows Components to be dynamically enabled and disabled, much like the system employed by Unity3D. For example, all Components are implicitly enabled by default; however, if one desires to halt execution of code for a particular Component, one can disable it. Naively, I want to have a boolean flag in Component (which is an abstract class), and somehow serialize all method calls into strings, so that some sort of ComponentManager can check if a given Component is enabled/disabled before processing a method call on it. However, this is a pretty bad solution. I feel like I should employ some variation of the state paradigm, but I have yet to make progress. Any help would be greatly appreciated,

  • Missing error handling in Streaming-AJAX-Proxy Log

    - by Michael Freidgeim
    We are using AjaxProxy(FROM http://www.codeproject.com/KB/ajax/ajaxproxy.aspx) on our web site, but started to notice errors accessing log.txt file. I found that the file is created by Log class and doesn't have ability to switch it off and error handling. I've added reading file name from configuration and try/catch block   public static class Log     {         private static StreamWriter logStream;         private static object lockObject = new object ();     public static void WriteLine(string msg)         {                       string logFileName = ConfigurationExtensions.GetAppSetting("AjaxStreamingProxy.LogFile" ,"");                       if (logFileName.IsNullOrEmpty())                             return;                       try                      {                             if (logStream == null )                            {                                    lock (lockObject)                                   {                                           if (logStream == null )                                          {                            logStream = File.AppendText(Path .Combine(AppDomain.CurrentDomain.BaseDirectory, logFileName));                                          }                                   }                            }                            logStream.WriteLine(msg);                      }                       catch (Exception exc)                      {                             string ignoredMsg = String .Format("The error occured while logging {0}, but processing will continue.\n {1} ", exc);                             LoggerHelper.LogEvent(ignoredMsg, MyCategorySource, TraceEventType .Warning, true);                      }         }

  • Illegal offset type

    Hello, I am having trouble uploading a file through php. I check the file type at the beginning of the process and I get an error. This is the error I am getting: Warning: Illegal offset type in /balblabla/DBfunctions.inc.php on line 183 This is the printed out $_FILES var Array ( [Picture] = Array ( [name] = JPG.jpg [type] = image/jpeg [tmp_name] = /tmp/phpHlrNY8 [error] = 0 [size] = 192221 ) ) Here is the segment of code I am using that is giving me issues: function checkFile($file, $type) { if( in_array($_FILES[$file]['type'], $type) ){ // <--- LINE 183 return true; }//if return false; } // end checkFile() This is the line of code that calls the function if( checkFile( $_FILES['Picture'], array("image/jpeg") ) == true ){ //do stuff }// end if I have used this piece of code on dozens of websites on my own server so i am guessing that this is some different configuration option. How can i modify my code so that it works on this different server?

  • Temenos WealthManager: performance benchmark on Exadata

    - by Javier Puerta
    Temenos WealthManager is at work in financial institutions of all sizes. No matter the size, each of Temenos’ customers has one requirement in common: a need for fast technology. This led Temenos to conduct a performance benchmark, running its WealthManager platform on Oracle Exadata Database Machine. During the study, Temenos executed high-intensity financial engines two- to three-times faster than its previous internal benchmarks and/or largest customer throughput. The company also demonstrated greater than two-times the average improvement in response times for six-times the number of users and data volumes. Further, Temenos secured a two-times gain in service-level agreements for batch and user-oriented workloads via dedicated or parallelized processing windows. Last year Temenos also communicated the availability of its T24 core banking system and how the benchmark run demonstrated the ability of Oracle’s Exadata platform to comfortably support the highest banking volumes for T24.

  • LinkButton child controls render

    - by Alex
    Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

  • Care to be taken when serving static content (JS, CSS, Media) from different domain?

    - by Aahan Krish
    Let me try to explain by example. Say website is hosted at example.com (NOT www.example.com). In order to serve static content cookie-free, I've chosen to use a different domain example-static.com. Now, lets consider that my static content is currently served like this: http://example.com/js/script.js http://example.com/css/style.css http://example.com/media/image.jpg ** Now I create a CNAME record aliasing example-static.com to my main domain i.e. example.com so that the static content is served as such: http://example-static.com/js/script.js http://example-static.com/css/style.css http://example-static.com/media/image.jpg ** Is that all I have to do? Will all browsers execute JavaScript files and load web fonts without any security concerns? OR should I be using some .htaccess rules to modify header information and the like? PS: It would be great if you can provide what rules should be added, if need be.

  • Upload/Download files with ASP.Net using Visual Studio Web Server

    - by jlnorsworthy
    I need to upload image files and store them on the webserver, then be able to display them in html. I'm currently using AppDomain.CurrentDomain.BaseDirectory to get a path to read and write files. Firefox won't display the image as I just get an img tag with "src='C:...' Is it possible to read/write files like this with Visual Studio web server? I know it'll be possible with IIS, but I don't want to do that if I don't have to (pretty new to web development) I'm implementing this with ASP.Net MVC 2, but I don't think that is relevant.

  • Produce high-quality, custom-size thumbnails from Office documents on Windows?

    - by Edwin
    Hi, What do you think would be the best way to produce custom size image thumbnail from MS Office documents (doc, xls and ppt) on Windows with native code (means all means besides .NET/JAVA)? My current research result: IExtractImage COM. Problem: The size of the generated result is fixed and low quality, and you can't be sure all the source documents contain the thumbnails. Use a programmable virtual printer to print the specified page, and the printer must support image output, any good suggestion for this? What else would you suggest? thanks!

  • Help! Obj-C/Iphone programming: extracting string from html text and reading off line by line

    - by royden
    hihi, I have this html text response from a particular website: <tr><td valign="top"><img src="/icons/image2.gif" alt="[IMG]"></td><td><a href="crsdsdfs2221.jpg">crash-2221.jpg</a></td><td align="right">14-Jun-2010 14:29 Notice for every line, there is this href=".__", which is an image file with random name and random format. I would like to extract that string within the inverted commas out so that i can append it into a URL path and download the image. I've been looking through this documentation from apple: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/strings/Articles/SearchingStrings.html#//apple_ref/doc/uid/20000149-CJBBGBAI on String programming but couldn't find one that fits my bill. Also after reading it, what code can I use to ensure that I will be reading the next line the next time my function is called( because I want to download the next picture). Hope some kind soul can help me out, thanks!
