  • PHP mysqli Insert not working, but not giving any errors.

    - by asdasdas
    As the title says Im trying to do a simple insert, but nothing actually is inserted into the table. I try to print out errors, but nothing is reported. My users table has many more fields than these 4, but they should all default. $query = 'INSERT INTO users (username, password, level, name) VALUES (?, ?, ?, ?)'; if($stmt = $db -> prepare($query)) { $stmt -> bind_param('ssis', $username, $password, $newlevel, $realname); $stmt -> execute(); $stmt -> close(); echo 'Any Errors: '.$db->error.PHP_EOL; } There are no errors given, but when I go to look at the table in phpmyadmin there is not a new row added. I know for sure that the types are correct (strings and integers). Is there something really wrong here or does it have something to do with the fact that I'm ignoring other columns. I have about 8 columns in the user table.

  • Class/Model Level Validation (as opposed to Property Level)? (ASP.NET MVC 2.0)

    - by Erx_VB.NExT.Coder
    Basically, what the title says. I have several properties that combine together to really make one logical answer, and i would like to run a server-side validation code (that i write) which take these multiple fields into account and hook up to only one validation output/error message that users see on the webpage. I looked at scott guthries method of extending an attribute and using it in yoru dataannotations declarations, but, as i can see, there is no way to declare a dataannotations-style attribute on multiple properties, and you can only place the declarations (such as [Email], [Range], [Required]) over one property :(. i have looked at the PropertiesMustMatchAttribute in the default mvc 2.0 project that appears when you start a new project, this example is as useful as using a pair of pins to check your motor oil - useless! i have tried this method, however, creating a class level attribute, and have no idea how to display the error from this in my aspx page. i have tried html.ValidationMessage("ClassNameWhereAttributeIsAdded") and a variety of other thing, and it has not worked. and i should mention, there is NOT ONE blog post on doing validation at this level - despite this being a common need in any project or business logic scenario! can anyone help me in having my message displayed in my aspx page, and also if possible a proper document or reference explaining validation at this level?

  • Can't operator == be applied to generic types in C#?

    - by Hosam Aly
    According to the documentation of the == operator in MSDN, For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object. For the string type, == compares the values of the strings. User-defined value types can overload the == operator (see operator). So can user-defined reference types, although by default == behaves as described above for both predefined and user-defined reference types. So why does this code snippet fail to compile? void Compare<T>(T x, T y) { return x == y; } I get the error Operator '==' cannot be applied to operands of type 'T' and 'T'. I wonder why, since as far as I understand the == operator is predefined for all types? Edit: Thanks everybody. I didn't notice at first that the statement was about reference types only. I also thought that bit-by-bit comparison is provided for all value types, which I now know is not correct. But, in case I'm using a reference type, would the the == operator use the predefined reference comparison, or would it use the overloaded version of the operator if a type defined one? Edit 2: Through trial and error, we learned that the == operator will use the predefined reference comparison when using an unrestricted generic type. Actually, the compiler will use the best method it can find for the restricted type argument, but will look no further. For example, the code below will always print true, even when Test.test<B>(new B(), new B()) is called: class A { public static bool operator==(A x, A y) { return true; } } class B : A { public static bool operator==(B x, B y) { return false; } } class Test { void test<T>(T a, T b) where T : A { Console.WriteLine(a == b); } }

  • Unicode strings in my C# App are shown with question marks

    - by mrbamboo
    Hi, I have a header file in C++/CLR project, which contains some strings in different languages. arabic, english, german, chinese, french, japanese etc... I have a second project written in C#. Here I access the strings stored in the header file of the C++/CLR project. The encoding of the header file is Unicode - Codepage 1200 or UTF-8. the visual studio editor is able to display the strings correctly. At runtime I access these strings and assign them into a local String variable. Here I recognized that many strings are not shown correctly. Doesn't matter if I assign them or not. Accessing the original place (while debugging) shows me all the foreign strings with question marks. Especially chinese, just question marks. Example : "So?e St?ange ?ext in Ch?n?se" (This is not the best example, I know) What is the problem? I read that C# is by default UTF-16, My header file containing the strings is UTF-16 or UTF-8. I must be able to handle strings in different languages. What am I doing wrong?

  • Git push current branch to a remote with Heroku

    - by cmaughan
    I'm trying to create a staging branch on Heroku, but there's something I don't quite get. Assuming I've already created a heroku app and setup the remote to point to staging-remote, If I do: git checkout -b staging staging-remote/master I get a local branch called 'staging' which tracks staging-remote/master - or that's what I thought.... But: git remote show staging-remote Gives me this: remote staging Fetch URL: [email protected]:myappname.git Push URL: [email protected]:myappname.git HEAD branch: master Remote branch: master tracked Local branch configured for 'git pull': staging-remote merges with remote master Local ref configured for 'git push': master pushes to master (up to date) As you can see, the pull looks reasonable, but the default push does not. It implies that if I do: git push staging-remote I'm going to push my local master branch up to the staging branch. But that's not what I want.... Basically, I want to merge updates into my staging branch, then easily push it to heroku without having to specify the branch like so: git push staging-remote mybranch:master The above isn't hard to do, but I want to avoid accidentally doing the previous push and pushing the wrong branch... This is doubly important for the production branch I'd like to create! I've tried messing with git config, but haven't figured out how to get this right yet...

  • How to deal with recursive dependencies between static libraries using the binutils linker?

    - by Jack Lloyd
    I'm porting an existing system from Windows to Linux. The build is structured with multiple static libraries. I ran into a linking error where a symbol (defined in libA) could not be found in an object from libB. The linker line looked like g++ test_obj.o -lA -lB -o test The problem of course being that by the time the linker finds it needs the symbol from libA, it has already passed it by, and does not rescan, so it simply errors out even though the symbol is there for the taking. My initial idea was of course to simply swap the link (to -lB -lA) so that libA is scanned afterwards, and any symbols missing from libB that are in libA are picked up. But then I find there is actually a recursive dependency between libA and libB! I'm assuming the Visual C++ linker handles this in some way (does it rescan by default?). Ways of dealing with this I've considered: Use shared objects. Unfortunately this is undesirable from the perspective of requiring PIC compliation (this is performance sensitive code and losing %ebx to hold the GOT would really hurt), and shared objects aren't needed. Build one mega ar of all of the objects, avoiding the problem. Restructure the code to avoid the recursive dependency (which is obviously the Right Thing to do, but I'm trying to do this port with minimal changes). Do you have other ideas to deal with this? Is there some way I can convince the binutils linker to perform rescans of libraries it has already looked at when it is missing a symbol?

  • Java: Handling cookies when logging in with POST

    - by Cris Carter
    I'm having quite some trouble logging in to any site in Java. I'm using the default URLconnection POST request, but I'm unsure how to handle the cookies properly. I tried this guide: http://www.hccp.org/java-net-cookie-how-to.html But couldn't get it working. I've been trying basically for days now, and I really need help if anyone wants to help me. I'll probably be told that it's messy and that I should use a custom library meant for this stuff. I tried downloading one, but wasn't sure how to get it set up and working. I've been trying various things for hours now, and it just won't work. I'd rather do this with a standard URLconnection, but if anyone can help me get another library working that's better for this, that would be great, too. I would really appreciate if someone could post a working source that I could study. What I need is: POST login data to site - Get and store the cookie from the site - use cookie with next URLconnection requests to get logged-in version of the site. Can anyone help me with this? Would be EXTREMELY appreciated. It really does mean a lot. If anyone wants to actually help me out live, please leave an instant-messenger address. Thank you a lot for your time.

  • Translate an exception into 404 from Application_Error

    - by Dmitriy Nagirnyak
    Hi, First of all, quickly what exactly I want to achieve: translate particular exception into the HTTP 404 so the ASP.NET can handle it further. I am handling exceptions in the ASP.NET (MVC2) this way: protected void Application_Error(object sender, EventArgs e) { var err = Server.GetLastError(); if (err == null) return; err = err.GetBaseException(); var noObject = err as ObjectNotFoundException; if (noObject != null) HandleObjectNotFound(); var handled = noObject != null; if (!handled) Logger.Fatal("Unhandled exception has occured in application.", err); } private void HandleObjectNotFound() { Server.ClearError(); Response.Clear(); // new HttpExcepton(404, "Not Found"); // Throw or not to throw? Response.StatusCode = 404; Response.StatusDescription = "Not Found"; Response.StatusDescription = "Not Found"; Response.Write("The whole HTML body explaining whata 404 is??"); } The problem is that I cannot configure default customErrors to work with it. When it is on then it never redirects to the page specified in customErrors: <error statusCode="404" redirect="404.html"/>. I also tried to raise new HttpExcepton(404, "Not Found") from the handler but then the response code is 200 which I don't understand why. So the questions are: What is the proper way of translating AnException into HTTP 404 response? How does customErrors section work when handling exceptions in Application_Error? Why throwing HttpException(404) renders (blank) page with success (200) status? Thanks, Dmitriy.

  • Automatically resize jQuery UI dialog to the width of the content loaded by ajax

    - by womp
    I'm having a lot of trouble finding specific information and examples on this. I've got a number of jQuery UI dialogs in my application attached to divs that are loaded with .ajax() calls. They all use the same setup call: $(".mydialog").dialog({ autoOpen: false, resizable: false, modal: true }); I just want to have the dialog resize to the width of the content that gets loaded. Right now, the width just stays at 300px (the default) and I get a horizontal scrollbar. As far as I can tell, "autoResize" is no longer an option for dialogs, and nothing happens when I specify it. I'm trying to not write a separate function for each dialog, so .dialog("option", "width", "500") is not really an option, as each dialog is going to have a different width. Specifying width: 'auto' for the dialog options just makes the dialogs take up 100% of the width of the browser window. What are my options? I'm using jQuery 1.4.1 with jQuery UI 1.8rc1. It seems like this should be something that is really easy. EDIT: I've implemented a kludgy workaround for this, but I'm still looking for a better solution.

  • parameterized doctype in xsl:stylesheet

    - by Flavius
    How could I inject a --stringparam (xsltproc) into the DOCTYPE of a XSL stylesheet? The --stringparam is specified from the command line. I have several books in docbook5 format I want to process with the same customization layer, each book having an unique identifier, here "demo", so I'm running something like xsltproc --stringparam course.name demo ... for each book. Obviously the parameter is not recognized as such, but as verbatim text, giving the error: warning: failed to load external entity "http://edu.yet-another-project.com/course/$(course.name)/entities.ent" Here it is how I've tried, which won't work: <?xml version='1.0'?> <!DOCTYPE stylesheet [ <!ENTITY % myent SYSTEM "http://edu.yet-another-project.com/course/$(course.name)/entities.ent"> %myent; ]> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <!-- the docbook template used --> <xsl:import href="http://docbook.org/ns/docbook/xhtml/chunk.xsl"/> <!-- processor parameters --> <xsl:param name="html.stylesheet">default.css</xsl:param> <xsl:param name="use.id.as.filename">1</xsl:param> <xsl:param name="chunker.output.encoding">UTF-8</xsl:param> <xsl:param name="chunker.output.indent">yes</xsl:param> <xsl:param name="navig.graphics">1</xsl:param> <xsl:param name="generate.revhistory.link">1</xsl:param> <xsl:param name="admon.graphics">1</xsl:param> <!-- here more stuff --> </xsl:stylesheet> Ideas?

  • Problem with sfRemember cookie / sfGuard Remember me

    - by Tom
    I'm using Symfony 1.4 with Doctrine. Sorry if this is a silly question but what exactly does one need to build on top of the sfDoctrineGuardPlugin to get the "remember me" functionality working? When I login a user, the sfRemember cookie is created with the default 15-day lifetime, and the remember key is saved in the plugin's sf_guard_remember_key table. Without any tweaks to the plugin, the sfGuardSecurityUser SignIn() method creates the cookie, but the Signout() method erases it, leaving no cookie unless you're logged in! Signin(): sfContext::getInstance()->getResponse()->setCookie($remember_cookie, $key, time() + $expiration_age); Signout(): sfContext::getInstance()->getResponse()->setCookie($remember_cookie, '', time() - $expiration_age); I can see that the database table saves the cookie as a relation of sf_guard_user, but that's not much good if the cookie is gone.... I'd be grateful if someone could tell me what I'm missing here, and ideally, if I prevent the Signout() method from removing the cookie, do I need to write code to read the cookie myself or is this automated somewhere/somehow? I've got box-standard Symfony 1.4 and sfDoctrineGuardPlugin installations. It all just seems totally wrong and the documentation on this is non-existent. Any help would appreciated.

  • How to use ASP.NET Routing in a Quote of the Day Website

    - by SidC
    Good Afternoon, A client is interested in creating an ASP.NET 2.0 website whose purpose is to serve up a "quote of the day". He wants the quotes on static content pages all attached to the same master page. The quote pages must be viewed in a certain sequence, and site browsers cannot view any other pages than the starting page when browsing to the site. That is, everyone must go to page 001.aspx when entering the site. Two Questions: 1. The content pages are going to be created by the client using an excel data source and a merge process by which each quote page is created eg. 001.aspx, 002.aspx etc. This seems clunky to me at best. Would ASP.NET Dynamic Data be a better solution here? I'm new to ASP.NET Routing and URL Rewriting as a whole. How would I setup a route table to ensure that users always entered the site on the same entry page, and create a route table such that default.aspx resolves to 001.aspx? Thanks, Sid

  • Missing WM_PAINT when hosting a WPF control inside a winforms application.

    - by Boris
    Hi All, Consider the following scenario: 1) Create a winforms application with an empty form. 2) Create a WPF usercontrol in the same project which is just the default control with background changed to blue. <UserControl x:Class="WindowsFormsApplication2.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" Background="Blue"> <Grid> </Grid> </UserControl> 3) Build the project 4) Add the control to your form (an ElementHost is added and the control is added inside it). 5) Run the application (everything looks nice) 6) Start Spy++, click find window (Control+F) and move the cursor onto the WPF control (the blue square) Something strange happens, the control gets a WM_ERASEBKGND message but no WM_PAINT message so now it is white. You can resize the form, hide the form behind other windows and the WPF control will not get rendered. There is an image of the scenario here: http://img260.imageshack.us/img260/2296/wmpaint.png This is a simplified example of the situation I have in the actual application. Please tell me what is the best way to resolve this issue such that the WPF control renders itself correctly. I would like a solution that can be incorporated into a large application with many controls on the form. Thank you very much in advance, Boris

  • How to display a subview loaded from a separate NIB file

    - by Marcus Netter
    I'm developing a Cocoa desktop application that uses a source list in the style of iTunes: different elements in the source list cause the main content area to display different views. The content area is entirely filled with a (vertical) NSSplitView; on the left is an NSOutlineView source list. When the user selects an item on the left, the relevant view appears on the right side of the splitter. I can make it work well enough by putting everything in one NIB file and putting a borderless NSTabView to the right of the splitter; to switch views, I just have to change the selected tab. But putting all the views in one NIB is bad practice, so I'm trying to move each of the subviews into their own NIB files. I have a pretty good idea of most of this process — I've created an NSViewController subclass for each of these views (EntityDetailViewController, GroupDetailViewController, and so on), set the File's Owner of each new NIB to the relevant controller class, set the view connection in each NIB, and reworked the bindings. What I don't know is how to actually change which subview is being shown on screen. I've tried using the default generic NSView on the right side and sending it addSubview: messages; I've tried connecting to it as the first subview and calling NSView *newSubview = /* get subview from the new subview controller */ [[subview superview] replaceSubview:subview with:newSubview]; [self setSubview:newSubview]; But everything just leaves the space blank. How do I display a subview loaded from a separate NIB?

  • Django Form Preview

    I'm trying to use django's FormPreview and I can't get it to work properly. Here's my code: forms.py class MyForm(forms.ModelForm): status = forms.TypedChoiceField( coerce=int, choices=LIST_STATUS, label="type", widget=forms.RadioSelect ) description = forms.CharField(widget = forms.Textarea) stage = forms.CharField() def __init__(self, useradd=None, *args, **kwargs): super(MyForm, self).__init__(*args, **kwargs) self.fields['firm'].label = "Firm" class Meta: model = MyModel fields = ['status', 'description', 'stage'] class MyFormPreview(FormPreview): form_template = 'templates/post.html' preview_template = 'templates/review.html' def process_preview(self, request, cleaned_data): print "processed" def done(self, request, cleaned_data): print "done" # Do something with the cleaned_data, then redirect # to a "success" page. return HttpResponseRedirect('/') urls.py (r'^post/$', MyFormPreview(MyForm)), post.html <form id = "post_ad" action = "" method = "POST" enctype="multipart/form-data"> <table> {{form.as_table}} </table> <input type="submit" name="save" value="Post" /> </form> When I go to /post/ I get the correct form and I fill it out. When I submit the form it goes right back to /post/ but but there are no errors (I've tried displaying {{errors}}) and the form is empty. None of my print statements execute. I'm not sure what I'm missing. Can anyone help me out? I can't find any documentation besides what's on the django site. Also, what's the "preview" variable called that I should use in my preview.html template? {{preview}} or do I just do {{form}} again? -- Answered below. I tried adding 'django.contrib.formtools' to my installed_apps in settings and I tried using the code from the default form templates from django.contrib as suggested below. Still, when I submit the form I go right back to the post template, none of my print statements execute :(

  • How do I change the color settings in emacs23 running in a terminal emulator?

    - by Anonymous
    I use xterm and set its appearance in ~/.Xdefaults: XTerm*background: paleTurquoise XTerm*foreground: black I also use emacs, but set its appearance differently in ~/.emacs: (set-background-color "black") (set-foreground-color "yellow") I usually run emacs within the terminal emulator with emacs -nw, rather than creating a separate X window. For some reason, this doesn't work properly for emacs23; instead, emacs retains the pale turquoise background of my xterm window. Looking at what's new in emacs23, I noted that: ** When running in a new enough xterm (newer than version 242), Emacs asks xterm what the background color is and it sets up faces accordingly for a dark background if needed (the current default is to consider the background light). So it's a feature, not a bug? Anyway, is there some way that I can I tell emacs23 to ignore the xterm background settings when running in console mode, and use the settings in ~/.emacs instead? I'll also note that: It works fine in emacs23 running in a separate X window (without the -nw option). It worked fine in emacs22; and I'm not really sure whether I need to use emacs23... Running M-x set-background-color within emacs23 -nw has no effect. It's not just xterm: the same problem exists with $TERM=cygwin, for example.

  • Duplicate method 'ProcessRequest' in ASPX

    - by Mauricio Scheffer
    I'm trying to code ASP.NET MVC views (WebForms view engine) in F#. I can already write regular ASP.NET WebForms ASPX and it works ok, e.g. <%@ Page Language="F#" %> <% for i in 1..2 do %> <%=sprintf "%d" i %> so I assume I have everything in my web.config correctly set up. However, when I make the page inherit from ViewPage: <%@ Page Language="F#" Inherits="System.Web.Mvc.ViewPage" %> I get this error: Compiler Error Message: FS0442: Duplicate method. The abstract method 'ProcessRequest' has the same name and signature as an abstract method in an inherited type. The problem seems to be this piece of code generated by the F# CodeDom provider: [<System.Diagnostics.DebuggerNonUserCodeAttribute>] abstract ProcessRequest : System.Web.HttpContext -> unit [<System.Diagnostics.DebuggerNonUserCodeAttribute>] default this.ProcessRequest (context:System.Web.HttpContext) = let mutable context = context base.ProcessRequest(context) |> ignore when I change the Page directive to use C# instead, the generated code is: [System.Diagnostics.DebuggerNonUserCodeAttribute()] public new virtual void ProcessRequest(System.Web.HttpContext context) { base.ProcessRequest(context); } which of course works fine and AFAIK is not semantically the same as the generated F# code. I'm using .NET 4.0.30319.1 (RTM) and MVC 2 RTM

  • Android Custom Dialog NullPointerException

    - by Kyle Hughes
    I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

    Hi, I want to place an image inside my custom control , so my generic.xaml looks like below: <Style TargetType="local:generic"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="local:generic"> <Grid Background="{TemplateBinding Background}"> <Rectangle> <Rectangle.Fill> <SolidColorBrush x:Name="BackgroundBrush" Opacity="0" /> </Rectangle.Fill> </Rectangle> <TextBlock Text="{TemplateBinding Text}" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="{TemplateBinding Foreground}"/> <Image Source="{TemplateBinding Source}" HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> My Codebehind is as follows: public class Generic : Control { public static DependencyProperty ImageUri = DependencyProperty.Register("Source", typeof(Uri), typeof(generic), new PropertyMetadata("")); public Uri Source { get { return (Uri)GetValue(generic.ImageUri); } set { SetValue(generic.ImageUri, value); } } public generic() { this.DefaultStyleKey = typeof(generic); } } Apllication is compiling fine but while I am trying to run it throws the following exception : $exception {System.Windows.Markup.XamlParseException: System.TypeInitializationException: The type initializer for 'testCstmCntrl.themes.generic' threw an exception. ---> System.ArgumentException: Default value type does not match type of property. Thanks, Subhen

  • How to handle missing files on MVC

    - by kaivalya
    What is your preferred way to handle hits to files that does not exist on your MVC app. I have couple of web apps runing with MVC and they are constantly getting hits for files folders etc. that does not exist in the app structure. Apps are throwing exception: The controller for path could not be found or it does not implement IController I am trying to find out the best way to handle this. I have 3 global routes on my global.asax file (see below) and at this point I am happy with that simple definition. I know if I added route definition for all controllers then I can add a definition to ignore the rest and handle these hits but if it will be possible to solve this problem without it, I do not want to add route definitions for each controller which I believe will flood the route definitions and also add a layer of maintenance which I don't like. //Aggregates 2nd level routes.MapRoute( "AggregateLevel2", "{controller}/{action}/{id}/{childid}/{childidlevel2}", new { controller = "Home", action = "Index", id = "", childid = "", childidlevel2 = "" } ); //Aggregates 1st level routes.MapRoute( "AggregateLevel1", "{controller}/{action}/{id}/{childid}", new { controller = "Home", action = "Index", id = "", childid = "" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

  • Can I use Data URLs in Android 2.1's Webkit-based browser?

    - by Sven Haiges
    Hi all, I am writing a tutorial about the HTML5 Canvas for mobile and did some basic tests. While I can call the getDataURL() Method on an iPhone's HTML5 Canvas Element, it does not seem to return the data URL on Android 2.1 (Google Nexus One) and it's webkit-based default browser. Here is the sample: var dataURL = canvas.toDataURL(); var img = document.createElement('img'); img.setAttribute('src', dataURL); document.getElementById('box').appendChild(img); This will work on iPhone, it will add a new image element with the same content as the canvas. It does nothing or fails on Android 2.1. Has anyone ever gotten this to work? I am also wondering if anyone could help me with understanding the WebKit Build numbers and what it means with regards to what features I can expect. For the iphone, I see a build number of 528.18, on Android 2.1's Browser I see (from the user agent strign) a WebKit build 530.17. So it looks Android 2.1's webkit browser is more up to date, still some features work on iPhone's webkit but not on Android. Does this comparison just make no sense? Thanx all!

  • Flash AS2.0 and JavaScript/jQuery (ExternalInterface) Communication

    - by abysslogic
    Hi there, Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song. I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not? Thanks edit heres the code as of now: AS 2.0 import flash.external.ExternalInterface; ExternalInterface.addCallback('loadSong', null, flashFunction); function flashFunction (val) { extra = val; } JavaScript var flashObj = document.getElementById('VSPLAYER'); function loadSong(val) { return val } HTML <a href="javascript:loadSong('2')">Play song 2</a> <object id="VSPLAYER" type="application/x-shockwave-flash" data="vs_player.swf" width="280" height="90"> <param name="movie" value="vs_player.swf" /> <param name="allowscriptaccess" value="always" /> </object>
