  • DataGridView.CellValueChanged not firing on bound DataGridView

    - by Wesley
    When I change a value programatically in a DataTable that my DataGridView is bound to, the appropriate CellValueChanged event is not firing for the DataGridView. I'm trying to change a cell's background color based on cell value when the DataTable is filled with data without iterating through every row and checking each value.

  • Concatenate & Minify JS on the fly OR at build time - ASP.NET MVC

    - by Charlino
    As an extension to this question here Linking JavaScript Libraries in User Controls I was after some examples of how people are concatinating & minifying javascript on the fly OR at build time. I would also like to see how it then works into your master pages. I don't mind page specific files being minified and linked inidividually as they currently are (see below) but all the js files on the main master page (I have about 5 or 6) I would like concatenated and minified. Bonus points for anyone who also incorporates CSS concatenation & minification! :-) Current master page with the common js files that I would like concatenated & minified: <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <head runat="server"> ... BLAH ... <asp:ContentPlaceHolder ID="AdditionalHead" runat="server" /> ... BLAH ... <%= Html.CSSBlock("/styles/site.css") %> <%= Html.CSSBlock("/styles/jquery-ui-1.7.1.css") %> <%= Html.CSSBlock("/styles/jquery.lightbox-0.5.css") %> <%= Html.CSSBlock("/styles/ie6.css", 6) %> <%= Html.CSSBlock("/styles/ie7.css", 7) %> <asp:ContentPlaceHolder ID="AdditionalCSS" runat="server" /> </head> <body> ... BLAH ... <%= Html.JSBlock("/scripts/jquery-1.3.2.js", "/scripts/jquery-1.3.2.min.js") %> <%= Html.JSBlock("/scripts/jquery-ui-1.7.1.js", "/scripts/jquery-ui-1.7.1.min.js") %> <%= Html.JSBlock("/scripts/jquery.validate.js", "/scripts/jquery.validate.min.js") %> <%= Html.JSBlock("/scripts/jquery.lightbox-0.5.js", "/scripts/jquery.lightbox-0.5.min.js") %> <%= Html.JSBlock("/scripts/global.js", "/scripts/global.min.js") %> <asp:ContentPlaceHolder ID="AdditionalJS" runat="server" /> </body> Used in a page like this (which I'm happy with): <asp:Content ID="signUpContent" ContentPlaceHolderID="AdditionalJS" runat="server"> <%= Html.JSBlock("/scripts/pages/account.signup.js", "/scripts/pages/account.signup.min.js") %> </asp:Content> EDIT: What I'm using now Since asking this question, Microsoft have released their own JS & CSS compression library called Microsoft AJAX Minifier, I'd definitely recommend checking it out. It includes MSBuild tasks which are the duck's nuts.

  • Integrating POP3 client functionality into a C# application?

    - by flesh
    I have a web application that requires a server based component to periodically access POP3 email boxes and retrieve emails. The service then needs to process the emails which will involve: Validating the email against some business rules (does it contain a valid reference in the subject line, which user sent the mail, etc.) Analysing and saving any attachments to disk Take the email body and attachment details and create a new item in the database Or update an existing item where the reference matches the incoming email subject line What is the best way to approach this? I really don't want to have to write a POP3 client from scratch, but I need to be able to customize the processing of emails. Ideally I would be able to plug in some component that does the access and retrieval for me, returning arrays of attachments, body text, subject line, etc. ready for my processing... [ UPDATE: Reviews ] OK, so I have spent a fair amount of time looking into (mainly free) .NET POP3 libraries so I thought I'd provide a short review of some of those mentioned below and a few others: Pop3.net - free - works OK, very basic in terms of functionality provided. This is pretty much just the POP3 commands and some base64 encoding, but it's very straight forward - probably a good introduction Pop3 Wizard - commercial / some open source code - couldn't get this to build, missing DLLs, I wouldn't bother with this C#Mail - free - works well, comes with Mime parser and SMTP client, however the comments are in Japanese (not a big deal) and it didn't work with SSL 'out of the box' - I had to change the SslStream constructor after which it worked no problem OpenPOP - free - hasn't been updated for about 5 years so it's current state is .NET 1.0, doesn't support SSL but that was no problem to resolve - I just replaced the existing stream with an SslStream and it worked. Comes with Mime parser. Of the free libraries, I'd go for C#Mail or OpenPOP. I looked at a few commercial libraries: Chillkat, Rebex, RemObjects, JMail.net. Based on features, price and impression of the company I would probably go for Rebex and may in the future if my requirements change or I run into production issues with either of C#Mail or OpenPOP. In case anyone's needs it, this is the replacement SslStream constructor that I used to enable SSL with C#Mail and OpenPOP: SslStream stream = new SslStream(clientSocket.GetStream(), false, delegate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors) { return true; });

  • How to change Jquery UI Slider handle

    - by Tom
    I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <style type="text/css"> #myhandle {position: absolute;z-index: 100;height: 25px;width: 35px;top: auto;background: url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat;} </style> <script type="text/javascript"> $(document).ready(function(){ $("#slider").slider({handle: '#myhandle'}); }); </script> </head> <body> <div id="slider"><div id="myhandle"></div></div> </body> </html> It is as if JQuery doesn't pick up that I want to use the myhandle id for the handle. I'm wondering: Do I need a plugin for JQuery to recognise the handle option? (it is not documented in http://docs.jquery.com/UI/Slider). Or perhaps it only worked in an old version of JQuery? Any ideas?

  • WPF XAML: how to get StackPanel's children to fill maximum space downward?

    - by Edward Tanguay
    I simply want flowing text on the left, and a help box on the right. The help box should extend all the way to the bottom. If you take out the outer StackPanel below it works great. But for reasons of layout (I'm inserting UserControls dynamically) I need to have the wrapping StackPanel. How do I get the GroupBox to extend down to the bottom of the StackPanel, as you can see I've tried: VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto" XAML: <Window x:Class="TestDynamic033.Test3" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test3" Height="300" Width="600"> <StackPanel VerticalAlignment="Stretch" Height="Auto"> <DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" Margin="10"> <GroupBox DockPanel.Dock="Right" Header="Help" Width="100" Background="Beige" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto"> <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" /> </GroupBox> <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch"> <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/> </StackPanel> </DockPanel> </StackPanel> </Window> Answer: Thanks Mark, using DockPanel instead of StackPanel cleared it up. In general, I find myself using DockPanel more and more now for WPF layouting, here's the fixed XAML: <Window x:Class="TestDynamic033.Test3" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test3" Height="300" Width="600" MinWidth="500" MinHeight="200"> <DockPanel VerticalAlignment="Stretch" Height="Auto"> <DockPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" MinWidth="400" Margin="10"> <GroupBox DockPanel.Dock="Right" Header="Help" Width="100" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" Height="Auto"> <Border CornerRadius="3" Background="Beige"> <TextBlock Text="This is the help that is available on the news screen." TextWrapping="Wrap" Padding="5"/> </Border> </GroupBox> <StackPanel DockPanel.Dock="Left" Margin="10" Width="Auto" HorizontalAlignment="Stretch"> <TextBlock Text="Here is the news that should wrap around." TextWrapping="Wrap"/> </StackPanel> </DockPanel> </DockPanel> </Window>

  • Rx Reactive extensions: Unit testing with FromAsyncPattern

    - by Andrew Anderson
    The Reactive Extensions have a sexy little hook to simplify calling async methods: var func = Observable.FromAsyncPattern<InType, OutType>( myWcfService.BeginDoStuff, myWcfService.EndDoStuff); func(inData).ObserveOnDispatcher().Subscribe(x => Foo(x)); I am using this in an WPF project, and it works great at runtime. Unfortunately, when trying to unit test methods that use this technique I am experiencing random failures. ~3 out of every five executions of a test that contain this code fails. Here is a sample test (implemented using a Rhino/unity auto-mocking container): [TestMethod()] public void SomeTest() { // arrange var container = GetAutoMockingContainer(); container.Resolve<IMyWcfServiceClient>() .Expect(x => x.BeginDoStuff(null, null, null)) .IgnoreArguments() .Do( new Func<Specification, AsyncCallback, object, IAsyncResult>((inData, asyncCallback, state) => { return new CompletedAsyncResult(asyncCallback, state); })); container.Resolve<IRepositoryServiceClient>() .Expect(x => x.EndRetrieveAttributeDefinitionsForSorting(null)) .IgnoreArguments() .Do( new Func<IAsyncResult, OutData>((ar) => { return someMockData; })); // act var target = CreateTestSubject(container); target.DoMethodThatInvokesService(); // Run the dispatcher for everything over background priority Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new Action(() => { })); // assert Assert.IsTrue(my operation ran as expected); } The problem that I see is that the code that I specified to run when the async action completed (in this case, Foo(x)), is never called. I can verify this by setting breakpoints in Foo and observing that they are never reached. Further, I can force a long delay after calling DoMethodThatInvokesService (which kicks off the async call), and the code is still never run. I do know that the lines of code invoking the Rx framework were called. Other things I've tried: I have attempted to modify the second last line according to the suggestions here: Reactive Extensions Rx - unit testing something with ObserveOnDispatcher No love. I have added .Take(1) to the Rx code as follows: func(inData).ObserveOnDispatcher().Take(1).Subscribe(x = Foo(x)); This improved my failure rate to something like 1 in 5, but they still occurred. I have rewritten the Rx code to use the plain jane Async pattern. This works, however my developer ego really would love to use Rx instead of boring old begin/end. In the end I do have a work around in hand (i.e. don't use Rx), however I feel that it is not ideal. If anyone has ran into this problem in the past and found a solution, I'd dearly love to hear it.

  • jQuery doesn't work in IE8?

    - by Wade D Ouellet
    Hi, I am working on a site here: mfm.treethink.net All the jquery works fine in Firefox, Chrome and Safari but on IE8 it gives me errors and the banner at the top doesn't work (which uses the crossSlide jQuery plugin) and as well the image rollovers don't work with the colour change. IE8 is telling me that the errors are on lines 53, 134 and 149 in the source, all of those lines are where the jquery function is declared. $(document).ready(function(){ I am running jquery 1.4. Oddly enough, the other piece of jQuery I have on that page works, the artist browse/select menu on the right. But the banner and image rollovers don't. Here are all the scripts I'm running: 1: the banner - doesn't work in IE8 <script type="text/javascript"> $(function() { $('#banner').crossSlide({ sleep: 5, fade: 1 }, [ <?php $pages = get_posts('numberposts=2000&post_type=artist&post_status=publish'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> { src: '/wp-content/uploads/<?php echo $page->post_name ?>.jpg' }, <?php $i++; } ?> ]); }); </script> 2 - image rollovers - doesn't work in IE8 <script type="text/javascript"> $(function(){ $("ul#artists li").hover(function() { /* On hover */ var thumbOver = $(this).find("img").attr("src"); /* Find image source */ /* Swap background */ $(this).find("a.thumb").css({'background' : 'url(' + thumbOver + ') center bottom no-repeat'}); $(this).find("span").stop().fadeTo('fast', 0 , function() { $(this).hide() }); } , function() { $(this).find("span").stop().fadeTo('fast', 1).show(); }); }); </script> 3 - the artist select - works in IE 8 <script> $("#browse-select").change(function() { window.location.href = $(this).val(); }); </script> These scripts were done by referencing previously made scripts, like I said I'm still new to jQuery. The second works in IE8 and the first one is the one that doesn't. I noticed the third one, the only one working, is written differently than the first two non-working ones without a function declaration at the top. Could this have anything to do with it? Any help figuring out this problem would be so appreciated. Thanks a lot, Wade

  • ASP Classic Session Variable Not Always Getting Set

    - by Mike at KBS
    I have a classic ASP site I'm maintaining and recently we wanted to do special rendering actions if the visitor was coming from one specific set of websites. So in the page where those visitors have to come through to get to our site, I put a simple line setting a session variable: <!-- #include virtual="/clsdbAccess.cs"--> <% set db = new dbAccess %> <html> <head> ... <script language="javascript" type="text/javascript"> ... </script> </head> <body> <% Session("CAME_FROM_NEWSPAPER") = "your local newspaper" ... %> ... html stuff ... </body> </html> Then, in all the following pages, whenever I need to put up nav links, menus, etc., that we don't want to show to those visitors, I test for if that session variable is "" or not, then render accordingly. My problem is that it seems to work great for me in development, then I get it out into Production and it works great sometimes, and other times it doesn't work at all. Sometimes the session variable gets set, sometimes it doesn't. Everything else works great. But our client is seeing inconsistent results on pages rendered to their visitors and this is a problem. I've tried logging on from different PC's and I confirm that I get different, and unpredictable, results. The problem is I can't reproduce it at will, and I can't troubleshoot/trace Production. For now I've solved this by just creating duplicate pages with the special rendering, and making sure those visitors go there. But this is a hack and will eventually be difficult to maintain. Is there something special or inconsistent about session variables in Classic ASP? Is there a better way to approach the problem? TIA.

  • Django: What's an awesome plugin to maintain images in the admin?

    - by meder
    I have an articles entry model and I have an excerpt and description field. If a user wants to post an image then I have a separate ImageField which has the default standard file browser. I've tried using django-filebrowser but I don't like the fact that it requires django-grappelli nor do I necessarily want a flash upload utility - can anyone recommend a tool where I can manage image uploads, and basically replace the file browse provided by django with an imagepicking browser? In the future I'd probably want it to handle image resizing and specify default image sizes for certain article types. Edit: I'm trying out adminfiles now but I'm having issues installing it. I grabbed it and added it to my python path, added it to INSTALLED_APPS, created the databases for it, uploaded an image. I followed the instructions to modify my Model to specify adminfiles_fields and registered but it's not applying in my admin, here's my admin.py for articles: from django.contrib import admin from django import forms from articles.models import Category, Entry from tinymce.widgets import TinyMCE from adminfiles.admin import FilePickerAdmin class EntryForm( forms.ModelForm ): class Media: js = ['/media/tinymce/tiny_mce.js', '/media/tinymce/load.js']#, '/media/admin/filebrowser/js/TinyMCEAdmin.js'] class Meta: model = Entry class CategoryAdmin(admin.ModelAdmin): prepopulated_fields = { 'slug': ['title'] } class EntryAdmin( FilePickerAdmin ): adminfiles_fields = ('excerpt',) prepopulated_fields = { 'slug': ['title'] } form = EntryForm admin.site.register( Category, CategoryAdmin ) admin.site.register( Entry, EntryAdmin ) Here's my Entry model: class Entry( models.Model ): LIVE_STATUS = 1 DRAFT_STATUS = 2 HIDDEN_STATUS = 3 STATUS_CHOICES = ( ( LIVE_STATUS, 'Live' ), ( DRAFT_STATUS, 'Draft' ), ( HIDDEN_STATUS, 'Hidden' ), ) status = models.IntegerField( choices=STATUS_CHOICES, default=LIVE_STATUS ) tags = TagField() categories = models.ManyToManyField( Category ) title = models.CharField( max_length=250 ) excerpt = models.TextField( blank=True ) excerpt_html = models.TextField(editable=False, blank=True) body_html = models.TextField( editable=False, blank=True ) article_image = models.ImageField(blank=True, upload_to='upload') body = models.TextField() enable_comments = models.BooleanField(default=True) pub_date = models.DateTimeField(default=datetime.datetime.now) slug = models.SlugField(unique_for_date='pub_date') author = models.ForeignKey(User) featured = models.BooleanField(default=False) def save( self, force_insert=False, force_update= False): self.body_html = markdown(self.body) if self.excerpt: self.excerpt_html = markdown( self.excerpt ) super( Entry, self ).save( force_insert, force_update ) class Meta: ordering = ['-pub_date'] verbose_name_plural = "Entries" def __unicode__(self): return self.title Edit #2: To clarify I did move the media files to my media path and they are indeed rendering the image area, I can upload fine, the <<<image>>> tag is inserted into my editable MarkItUp w/ Markdown area but it isn't rendering in the MarkItUp preview - perhaps I just need to apply the |upload_tags into that preview. I'll try adding it to my template which posts the article as well.

  • What is Jquery's alternative to Mootools MochaUI?

    - by chris
    MochaUI is very intuitive and the modal iframes almost perfectly replicate Windows. Unfortunately, I have scripts written in Jquery that I use, and I hear there are conflicts when putting both Mootools and Jquery on one html file (is this true?). How can I get the MochaUI features in Jquery? At the very least, is there a similar modal dialog system? I've seen JqueryUI Dialog but it makes the background go dark and nonfunctional, which is not what I am looking for.

  • Asynchronous COMET query with Tornado and Prototype

    - by grundic
    Hello everyone. I'm trying to write simple web application using Tornado and JS Prototype library. So, the client can execute long running job on server. I wish, that this job runs Asynchronously - so that others clients could view page and do some stuff there. Here what i've got: #!/usr/bin/env/ pytthon import tornado.httpserver import tornado.ioloop import tornado.options import tornado.web from tornado.options import define, options import os import string from time import sleep from datetime import datetime define("port", default=8888, help="run on the given port", type=int) class MainHandler(tornado.web.RequestHandler): def get(self): self.render("templates/index.html", title="::Log watcher::", c_time=datetime.now()) class LongHandler(tornado.web.RequestHandler): @tornado.web.asynchronous def get(self): self.wait_for_smth(callback=self.async_callback(self.on_finish)) print("Exiting from async.") return def wait_for_smth(self, callback): t=0 while (t < 10): print "Sleeping 2 second, t={0}".format(t) sleep(2) t += 1 callback() def on_finish(self): print ("inside finish") self.write("Long running job complete") self.finish() def main(): tornado.options.parse_command_line() settings = { "static_path": os.path.join(os.path.dirname(__file__), "static"), } application = tornado.web.Application([ (r"/", MainHandler), (r"/longPolling", LongHandler) ], **settings ) http_server = tornado.httpserver.HTTPServer(application) http_server.listen(options.port) tornado.ioloop.IOLoop.instance().start() if __name__ == "__main__": main() This is server part. It has main view (shows little greeting, current server time and url for ajax query, that executes long running job. If you press a button, a long running job executes. And server hangs :( I can't view no pages, while this job is running. Here is template page: <html> <head> <title>{{ title }}</title> <script type="text/javascript" language="JavaScript" src="{{ static_url("js/prototype.js")}}"></script> <script type='text/javascript' language='JavaScript'> offset=0 last_read=0 function test(){ new Ajax.Request("http://172.22.22.22:8888/longPolling", { method:"get", asynchronous:true, onSuccess: function (transport){ alert(transport.responseText); } }) } </script> </head> <body> Current time is {{c_time}} <br> <input type="button" value="Test" onclick="test();"/> </body> </html> what am I doing wrong?

  • WPF Memory Leak

    - by Oskar Kjellin
    I have an WPF form that I myself did not create, so I am not very good at WPF. It is leaking badly though, up to 400 MB and closing the form does not help. The problem lies in my application loading all the pictures at once. I would like to only load the ones visible at the moment. It is about 300 pictures and they are a bit large so my WPF-form suffers from loading them all. I have a DataTemplate with my own type that has a property Thumbnail. The code in the template is like this: <Image Source="{Binding Path=Thumbnail}" Stretch="Fill"/> And then I have a grid with a control that has the above template as source. The code for this control is the below. Please provide me with hints on how to optimize the code and perhaps get the only ones that are visible and only have that many controls loaded at the same time? <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Controls:ElementFlow"> <Grid Background="{TemplateBinding Background}"> <Canvas x:Name="PART_HiddenPanel" IsItemsHost="True" Visibility="Hidden" /> <Viewport3D x:Name="PART_Viewport"> <!-- Camera --> <Viewport3D.Camera> <PerspectiveCamera FieldOfView="60" Position="0,1,4" LookDirection="0,-1,-4" UpDirection="0,1,0" /> </Viewport3D.Camera> <ContainerUIElement3D x:Name="PART_ModelContainer" /> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White" /> </ModelVisual3D.Content> </ModelVisual3D> <Viewport2DVisual3D RenderOptions.CachingHint="Cache" RenderOptions.CacheInvalidationThresholdMaximum="2" RenderOptions.CacheInvalidationThresholdMinimum="0.5"/> </Viewport3D> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • How to access SVG elements with Javascript

    - by gargantaun
    I'm messing around with SVG and I was hoping I could create SVG files in Illustrator and access elements with Javascript. Here's the SVG file Illustrator kicks out (It also seems to add a load of junk to the beginning of the file that I've removed) <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="276.843px" height="233.242px" viewBox="0 0 276.843 233.242" enable-background="new 0 0 276.843 233.242" xml:space="preserve"> <path id="delta" fill="#231F20" d="M34.074,86.094L0,185.354l44.444,38.519l80.741-0.74l29.63-25.186l-26.667-37.037 c0,0-34.815-5.926-37.778-6.667s-13.333-28.889-13.333-28.889l7.407-18.519l31.111-2.963l5.926-21.481l-12.593-38.519l-43.704-5.185 L34.074,86.094z"/> <path id="cargo" fill="#DFB800" d="M68.148,32.761l43.704,4.445l14.815,42.963l-7.407,26.667l-33.333,2.963l-4.444,14.074 l54.074-1.481l22.222,36.296l25.926-3.704l25.926-54.074c0,0-19.259-47.408-21.481-47.408s-31.852-0.741-31.852-0.741 l-19.259-39.259L92.593,8.316L68.148,32.761z"/> <polygon id="beta" fill="#35FF1F" points="86.722,128.316 134.593,124.613 158.296,163.872 190.889,155.724 214.593,100.909 194.593,52.02 227.186,49.057 246.444,92.02 238.297,140.909 216.074,172.761 197.556,188.316 179.778,169.798 164.963,174.983 163.481,197.946 156.815,197.946 134.593,159.428 94.593,151.279 "/> <path class="monkey" id="alpha" fill="#FD00FF" d="M96.315,4.354l42.963,5.185l18.519,42.222l71.852-8.148l20.74,46.667l-5.926,52.593 l-24.444,34.074l-25.185,15.555l-14.074-19.259l-8.889,2.964l-1.481,22.222l-14.074,2.963l-25.186,22.963l-74.074,4.444 l101.481,4.444c0,0,96.297-17.777,109.63-71.852S282.24,53.983,250.389,20.65S96.315,4.354,96.315,4.354z"/> </svg> As you can probably see, each element has an ID, and I was hoping to be able to access individual elements with Javascript so I could change the Fill attribute and respond to events such as click. The HTML is bog basic <!DOCTYPE html> <html> <head> <title>SVG Illustrator Test</title> </head> <body> <object data="alpha.svg" type="image/svg+xml" id="alphasvg" width="100%" height="100%"></object> </body> </html> I guess this is two questions really. a) Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG. b) If it is possible, what's the technique?
