  • UIActivityViewController 101

    - by Anthony Guay
    I'm starting to get familiar with the new iOS 6 way to share: UIActivityViewController (the same as when you share a photo from the native iOS photo app), but I'm experiencing a few problems. First, when I choose to share via email, I can't find a way to set the subject of the email. Second, when I post on twitter, I can't find how to post a URL (except explicitly writing it in a NSString). Before, on iOS 5, I was using MFMailComposeViewController for Mail and SLComposeViewController for Twitter. It worked well. If there's no way to choose the subject with UIActivityViewController, could there be a way that I put my own custom buttons on the ActivityViewController, buttons that will call MFMailComposeViewController and SLComposeViewController when touched? I'm just speculating here. Thanks!

  • Redirect based on Accept-Language

    - by Anthony Faull
    I need to honor the web browser's list of language preferences. Supported languages are English and French. For example: http_accept_language="jp-JP;fr;en-US;en" redirects to a directory called /French/. How can I do this with rewrite rules in my .htaccess file?

  • YouTube API, jQuery attr won't swap element attributes (I think) in IE, but works in FF

    - by Anthony
    JavaScript (jQuery) function display_youtube(new_url) { $('#movie_url').removeAttr('value'); $('#embed_url').removeAttr('src'); $(document).ready(function() { $('#movie_url').attr('value', new_url); $('#embed_url').attr('src', new_url); $('#shade').css('display', 'block'); $('#youtube_player').css('display', 'block'); $('#exit_youtube').css('display', 'block'); }); } HTML <object width="720" height="480"> <param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" /> <param name="allowFullScreen" value="true" /> <param name="allowscriptaccess" value="always" /> <embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" /> </object> Hyperlink <a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a> What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?

  • Java "Pool" of longs or Oracle sequence with reusable values

    - by Anthony Accioly
    Several months ago I implemented a solution to choose unique values from a range between 1 and 65535 (16 bits). This range is used to generate unique Route Targets suffixes, which for this customer massive network (it's a huge ISP) are a very disputed resource, so any free index needs to become immediately available to the end user. To tackle this requirement I used a BitSet. Allocate on the RT index with set and deallocate a suffix with clear. The method nextClearBit() can find the next available index. I handle synchronization / concurrency issues manually. This works pretty well for a small range... The entire index is small (around 10k), it is blazing fast and can be easy serialized into a Blob field. The problem is, some new devices can handle RTs of 32 bits (range 1 / 4294967296). Which can't be managed with a BitSet (it would, by itself, consume around 600Mb, plus be limited to int range). Even with this massive range available, the client still wants to free available Route Targets for the end user, mainly because the lowest ones (up to 65535) - which are compatible with old routers - are being heavily disputed. Before I tell the customer that this is impossible and he will have to conform with my reusable index for lower RTs (up to 65550) and use a database sequence for the other ones (which means that when the user frees a Route Target, it will not become available again). Would anyone shed some light? Maybe some kind soul already implemented a high performance number pool for Java (6 if it matters), or I am missing a killer feature of Oracle database (11R2 if it matters)... Wishful thinking. Thank you very much in advance.

  • App is fast on 3GS but slow on 3G

    - by Anthony Chan
    Hi all, I'm new to computer coding and have just finished coding an app and tested it on both 3G and 3GS. On 3GS, it worked as normal as on the simulator. However, when I tried to run it on 3G, the app becomes extremely slow. I'm not sure what's the reason and I hope someone could shed some light on me. Generally, my app has a couple of view controller classes, with one of them being the title page, one being the main page, one is setting, etc. I used a dissolve to transition from the title page to the main page. But even this simple transition shows un-smooth performance on a 3G! My other part of the app involves zooming in to some images by scaling up the images, switching images by push or dissolve upon receiving touch events, saving photos into photo library and storing and retrieving some photos in a folder and some data in a SQlite database, each showing un-smooth actions. Compared with some heavy graphic or heavy maths app, I think mine is pretty simple. I totally have no clue why the app would behave so slow and un-smooth that it is barely useful on a 3G. Any help/ direction would be much appreciated. Thanks for helping out.

  • What's the best way to fix memory leaks on the iPhone?

    - by Anthony Glyadchenko
    I'm trying to use XCode's Leaks utility to fix some memory leaks in my code. Is there a better and more understandable way to check for leaks with explanations that pinpoint the exact line and/or offer suggestions? Another question, I'm using AVAudioRecorder in my code in one of my view controllers. Should I load the recorder in viewDidLoad or in viewWillAppear?

  • Oauth : Get user's permissions without any redirection to a server.

    - by Anthony
    Hello, in my website, I want to add a "invite friend of my contacts book" functionnality. I would like that the user fills the loggin form in my website. Then the website contacts Google Mail, Yahoo Mail, Live Mail and retrieves the contact list. In the Oauth protocole supported by Google and Yahoo, the user is redirected to a Google or Yahoo page (like Facebook) in order to permit the user to give permissions. But I saw two websites which didn't any redirections to get the contacts book (LinkedIn for a Google mail account and Theauteurs with a live mail.) Do you know how I can get a contacts book without redirect the user to Google, Microsoft or Yahoo website.

  • Does a lazy-programmer "document template" with tags exist for Windows?

    - by Anthony Forloney
    I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Does one, or could one, exist, preferably Windows based? Any information regarding this would be helpful.

  • How to catch an expected (and intended) 302 Ajax response?

    - by Anthony
    So, if you look back at my previous question about Exchange Autodiscover, you'll see that the easiet way to get the autodiscover URL is to send a non-secure, non-authenticated GET request to the server, ala: http://autodiscover.exchangeserver.org/autodiscover/autodiscover.xml The server will respond with a 302 redirect with the correct url in the Location header. I'm trying out something really simple at first with a Chrome extension, where I have: if (req.readyState==4 && req.status==302) { return req.getResponseHeader("Location"); } With another ajax call set up with the full XML Post and the user credentials, But instead Chrome hangs at this point, and a look at the developer panel shows that it is not returning back the response but instead is acting like no response was given, meanwhile showing a Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101 in the error log. The way I see it, refering to the exact response status is about the same as "catching" it, but I'm not sure if the problem is with Chrome/WebKit or if this is how XHR requests always handle redirects. I'm not sure how to catch this so that I can get still get the headers from the response. Or would it be possible to set up a secondary XHR such that when it gets the 302, it sends a totally different request? Quick Update I just changed it so that it doesn't check the response code: if (req.readyState==4) { return req.getResponseHeader("Location"); } and instead when I alert out the value it's null. and there is still the same error and no response in the dev console. SO it seems like it either doesn't track 302 responses as responses, or something happens after that wipes that response out?

  • I can't prevent key presses from changing a selected option in Firefox

    - by Anthony
    Using Firefox 3.5.7 The following test page should behave like Opera, Safari and Chrome. Key presses (arrows or 1-5) should have no effect (i.e. The events should be cancelled so that the number never changes from the initial default "3"). [I have separate working code for IE too]. Many thanks to anyone who can make it work? <html> <head> <title>Test</title> <script type='text/JavaScript'> function stop(evt) {evt.preventDefault(); evt.stopPropagation(); }; </script> </head> <body> <select onkeydown='stop(event);' onkeypress='stop(event);'> <option>1</option> <option>2</option> <option selected="selected">3</option> <option>4</option> <option>5</option> </select> </body> </html>

  • jquery append() method on empty XML element

    - by Anthony
    This could just be a syntax error, but I'm trying to create a Document object from scratch, starting with document.implementation.createDocument() and then using jquery's append() method to add the elements. But it's not appending: var myDoc = document.implementation.createDocument("", 'stuff', null); $("stuff",myDoc).attr("test","tested"); $("stuff",myDoc).append("<test>A</test>"); $("<test>B</test>").appendTo("stuff",soapEnv); var s = new XMLSerializer(); alert(s.serializeToString(soapEnv)); This should output: <stuff test="tested"> <test>A</test> <test>B</test> </stuff> But instead it outputs: <stuff test="tested" /> So the selector seems to be working, just not the method. My only guess is the method doesn't account for the fact that elements are empty (<stuff />) until they have children. But that's just a guess.

  • Initializing static pointer in templated class.

    - by Anthony
    This is difficult for me to formulate in a Google query (at least one that gives me what I'm looking for) so I've had some trouble finding an answer. I'm sure I'm not the first to ask though. Consider a class like so: template < class T > class MyClass { private: static T staticObject; static T * staticPointerObject; }; ... template < class T > T MyClass<T>::staticObject; // <-- works ... template < class T > T * MyClass<T>::staticPointerObject = NULL; // <-- cannot find symbol staticPointerObject. I am having trouble figuring out why I cannot successfully create that pointer object. Edit: The above code is all specified in the header, and the issue I mentioned is an error in the link step, so it is not finding the specific symbol.

  • Replacing symbol from object file at compile time. For example swapping out main

    - by Anthony Sottile
    Here's the use case: I have a .cpp file which has functions implemented in it. For sake of example say it has the following: [main.cpp] #include <iostream> int foo(int); int foo(int a) { return a * a; } int main() { for (int i = 0; i < 5; i += 1) { std::cout << foo(i) << std::endl; } return 0; } I want to perform some amount of automated testing on the function foo in this file but would need to replace out the main() function to do my testing. Preferably I'd like to have a separate file like this that I could link in over top of that one: [mymain.cpp] #include <iostream> #include <cassert> extern int foo(int); int main() { assert(foo(1) == 1); assert(foo(2) == 4); assert(foo(0) == 0); assert(foo(-2) == 4); return 0; } I'd like (if at all possible) to avoid changing the original .cpp file in order to do this -- though this would be my approach if this is not possible: do a replace for "(\s)main\s*\(" == "\1__oldmain\(" compile as usual. The environment I am targeting is a linux environment with g++.

  • How can I know if a file has been changed in .NET C#?

    - by Anthony D
    I have an application that requires a secure way to store its configuration. There are users that can change the configuration. I need some sort of signature scheme where I can verify that the config file has not changed with out a valid user. I had thought about using RSA, where the private key is encrypted with the users password, and the public key is used to sign the config. However there is nothing to prevent someone from changing the user file and adding their own public key, thus circumventing my security. Any ideas?

  • Android: Custom Clock widget Service work-around?

    - by Anthony Forloney
    I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, is there a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel? I have currently Retro Clock on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing. Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood? Any help is appreciated. EDIT: I believe implementing the service to update the clock would drain the battery life tremendously, any ideas on a work around or help shed some light on any performance issues with using Service?

  • Lightcore IoC is returning the same instance when it should give a new one

    - by Anthony
    I have the following code using the lightcore IoC container. But it fails with "NUnit.Framework.AssertionException: Contained objects are equal" which indicates that the objects that should be transient, are not. Is this a bug in lightcore, or am I doing it wrong? [Test] public void JellybeanDispenserHasNewInstanceEachTimeWithDefault() { var builder = new ContainerBuilder(); builder.Register<IJellybeanDispenser, VanillaJellybeanDispenser>(); builder.Register<SweetVendingMachine>().ControlledBy<TransientLifecycle>(); builder.Register<SweetShop>(); builder.DefaultControlledBy<TransientLifecycle>(); IContainer container = builder.Build(); SweetShop sweetShop = container.Resolve<SweetShop>(); SweetShop sweetShop2 = container.Resolve<SweetShop>(); Assert.IsFalse(ReferenceEquals(sweetShop, sweetShop2), "Root objects are equal"); Assert.IsFalse(ReferenceEquals(sweetShop.SweetVendingMachine, sweetShop2.SweetVendingMachine), "Contained objects are equal"); Assert.IsFalse(ReferenceEquals(sweetShop.SweetVendingMachine.JellybeanDispenser, sweetShop2.SweetVendingMachine.JellybeanDispenser), "services are equal"); } PS: I would tag this question with "lightcore", but suddenly my reputation isn't good enough to make a new tag. Huh.

  • Visual Studio 2010 element names for theming

    - by Anthony Potts
    I am trying to figure out what the element name for the tooltip is in Visual studio so that I can change the style using the extension found here. Anyone know what that is? I am using the default theme which seems to have a white to light grey gradient on it. This is less than optimal since the text for the functions are also white. In a more general question (and perhaps better), is there anything that maps the names as they are found in the theme to where they are in the IDE.
