  • MPMoviePlayerController - streaming works on 3GS, not on anything pre-3GS

    - by Canada Dev
    I am having some serious issues and annoyances with MPMoviePlayerController. In my app you can watch trailers for some movies in .mov format. I have tested with a friend and had users report that it does not work on their device, which are all 3G. I have tested on my own, a 3GS and playback works fine. I have tried on a 1st gen iPhone and it doesn't work. So I am lead to believe it's a memory issue, and that it's simply stopping the playback and returning to the previous screen. Below is the code I use to launch the player, which is straight out of the MoviePlayer example from Apple. MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:trailerURL]]; if (mp) { self.moviePlayer = mp; [mp release]; [self.moviePlayer play]; } I have tried to check the NSError from the notifications, but the only thing I get is "An unknown playback error occurred" for both the localizedDescription and localizedRecoverySuggestion, making it impossible to figure out exactly why it's not working. I have seen many examples of people who just have issues with the movie player, but it's starting to annoy me that it sometimes seem to work fine and other times it just doesn't (again, appearing like a memory issue). Thanks for any help/feedback provided

  • Compiling external C++ library (Octave) for iPhone (Fortran compiler missing?)

    - by Shaggy Frog
    A friend of mine asked me if it would be possible to port the Octave project to the iPhone. I haven't compiled an external package for an iPhone project before, so I downloaded the source code, and then used some scripts found on a couple of different Web sites (one, two) to try and build the libraries. However, when I try either of these scripts (which are nearly identical), they eventually die during the configure phase with the following error output: [...snip checks...] checking whether we are using the GNU Fortran 77 compiler... no checking whether accepts -g... no checking how to get verbose linking output from ... configure: WARNING: compilation failed checking for Fortran 77 libraries of ... rm: conftest.dSYM: is a directory checking for dummy main to link with Fortran 77 libraries... rm: conftest.dSYM: is a directory none checking for Fortran 77 name-mangling scheme... configure: error: cannot compile a simple Fortran program See `config.log' for more details. Is the problem that the iPhone SDK/Xcode doesn't include a Fortran cross-compiler, or am I doing something wrong?

  • Using singleton instead of a global static instance

    - by Farstucker
    I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } private Singleton() { APIClass api = new APIClass(); //Can this be done? } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? EDIT: I realize the Singleton class can be called with something like Singleton obj1 = Singleton.Instance(); but would I be able to access the methods within the APIs Class (ie. obj1.Start)? (not that I need to, just asking) EDIT #2: I might have been a bit premature in checking the answer but I do have one small thing that is still causing me problems. The API is launching just fine, unfortunately Im able to launch two instances? New Code public sealed class SingletonAPI { public static SingletonAPI Instance { get; private set; } private SingletonAPI() {} static SingletonAPI() { Instance = new SingletonAPI(); } // API method: public void Start() { API myAPI = new API();} } but if I try to do something like this... SingletonAPI api = SingletonAPI.Instance; api.Start(); SingletonAPI api2 = SingletonAPI.Instance; // This was just for testing. api2.Start(); I get an error saying that I cannot start more than one instance.

  • How to print a number with a space as thousand separator?

    - by dygi
    I've got a simple class Currency with overloaded operator<<. I don't know how can i separate the number with spaces every 3 digits, so it looks like: "1 234 567 ISK". #include <cstdlib> #include <iostream> using namespace std; class Currency { int val; char curr[4]; public: Currency(int _val, const char * _curr) { val = _val; strcpy(curr, _curr); } friend ostream & operator<< (ostream & out, const Currency & c); }; ostream & operator<< (ostream & out, const Currency & c) { out << c.val<< " " << c.curr; return out; } int main(int argc, char *argv[]) { Currency c(2354123, "ISK"); cout << c; } What interests me, is somehow the easiest solution for this particular situation.

  • Game login authentication and security.

    - by Charles
    First off I will say I am completely new to security in coding. I am currently helping a friend develop a small game (in Python) which will have a login server. I don't have much knowledge regarding security, but I know many games do have issues with this. Everything from 3rd party applications (bots) to WPE packet manipulation. Considering how small this game will be and the limited user base, I doubt we will have serious issues, but would like to try our best to limit problems. I am not sure where to start or what methods I should use, or what's worth it. For example, sending data to the server such as login name and password. I was told his information should be encrypted when sending, so in-case someone was viewing it (with whatever means), that they couldn't get into the account. However, if someone is able to capture the encrypted string, wouldn't this string always work since it's decrypted server side? In other words, someone could just capture the packet, reuse it, and still gain access to the account? The main goal I am really looking for is to make sure the players are logging into the game with the client we provide, and to make sure it's 'secure' (broad, I know). I have looked around at different methods such as Public and Private Key encryption, which I am sure any hex editor could eventually find. There are many other methods that seem way over my head at the moment and leave the impression of overkill. I realize nothing is 100% secure. I am just looking for any input or reading material (links) to accomplish the main goal stated above. Would appreciate any help, thanks.

  • how I can print WPF treeview items over multiple pages?

    - by RAJKISHOR
    Hello friend, I want to print tree structure showing in WPF treeview control in multiple page. I tried PrintVisual() but it only prints only visible parts. Then I tried FlowDocument and written AddNode(), but its not showing the same result as treeview doimg. Please help me with code. public void AddNodes(int uid, ListItem tSubNode) { string query = "select fullname, id from members where refCode=" + uid + ";"; String memValue; MySqlCommand cmd = new MySqlCommand(query, db.conn); MySqlDataAdapter _DA = new MySqlDataAdapter(cmd); DataTable _DT = new DataTable(); _DA.Fill(_DT); ListOffset += 20; foreach (DataRow _dr in _DT.Rows) { ListItem tNode = new ListItem(); tNode.Margin = new Thickness(ListOffset,0,0,0); memValue = _dr["fullname"].ToString() + " (" + _dr["id"].ToString() + ")"; tNode.Blocks.Add(new Paragraph(new Run(hyp+memValue))); myList.ListItems.Add(tNode); flowDoc.Blocks.Add(myList); _fdrMembers.Document = flowDoc; if (db.HasMembers(Convert.ToInt32(_dr["id"].ToString()))) { AddNodes(Convert.ToInt32(_dr["id"]), tNode); } } ListOffset = 20; } private void button_Click(object sender, RoutedEventArgs e) { ListOffset = 0; myList.ListItems.Clear(); tSuper.Blocks.Clear(); if (db.GetNameByUID(100001) != null) { tSuper.Blocks.Add(new Paragraph(new Run(db.GetNameByUID(100001)))); myList.ListItems.Add(tSuper); AddNodes(100001, tSuper); } MessageBox.Show("Member by ID - "+does.ToString()+", "+dosnt.ToString(), "Error!", MessageBoxButton.OK, MessageBoxImage.Information); }**strong text**

  • Should I map a domain object to a view model using an optional constructor?

    - by Byron Sommardahl
    I'd like to be able to map a domain model to a view model by newing up a view model and passing in the contributing domain model as a parameter (like the code below). My motivation is to keep from re-using mapping code AND to provide a simple way to map (not using automapper yet). A friend says the view model should not know anything about the "payment" domain model that's being passed into the optional constructor. What do you think? public class LineItemsViewModel { public LineItemsViewModel() { } public LineItemsViewModel(IPayment payment) { LineItemColumnHeaders = payment.MerchantContext.Profile.UiPreferences.LineItemColumnHeaders; LineItems = LineItemDomainToViewModelMapper.MapToViewModel(payment.LineItems); ConvenienceFeeAmount = payment.ConvenienceFee.Fee; SubTotal = payment.PaymentAmount; Total = payment.PaymentAmount + payment.ConvenienceFee.Fee; } public IEnumerable<Dictionary<int, string>> LineItems { get; set; } public Dictionary<int, string> LineItemColumnHeaders { get; set; } public decimal SubTotal { get; set; } public decimal ConvenienceFeeAmount { get; set; } public decimal Total { get; set; } }

  • If I wanted to make a Pac-Man Game?

    - by SoulBeaver
    I am immediately placing this as a community wiki thing. I don't want to ask for help in programming yet or have even a specific question about programming, but rather the process and the resources needed to make such a game. To put it simply: My college friend and I decided to give ourselves a really big challenge to further our skills in programming. In six months time we want to show ourselves a Pac-Man game. Pac-Man will be AI-controlled like the Ghosts and whichever Pac-Man lives the longest after a set of tries wins. This isn't like anything we've done so far. The goal here, for me, isn't to create a perfect game, but to try and complete it, learn a whole bunch in the process. Even if I don't finish in the time, which is a good possibility, I would want to have at least tried this. So my question is this: How should I start preparing myself? I already have started vector math, matrices, all that fun stuff. My desired platform would be DirectX 9.0c; is that advisable? Keep in mind that this is not a preference just for this project, but I wish to have some kind of future in graphics develepment, so I want to pick a platform that is future-safe. As for the game development in general, what should I take into consideration? I have never done a real game before, so any and all advise to development of mid-scale projects( if this would be a mid-scale project ) is greatly appreciated. My main concerns are the pit-falls and demotivators. Sorry if the question is so vague. If it doesn't belong here, then I will remove it. Otherwise, any and all advise regarding making larger projects is greatly appreciated.

  • Javascript won't execute in iPhone Safari

    - by Stuart Meyer
    I'm running into this issue only because I recently purchased an iPhone. The javascript for a picture carousel on my website (http://www.stuartmeyerphotography.com) won't execute in Safari for iPhone. I thought it worked on Mac Safari last I checked with a friend who had a Mac (a year ago), but now I need to go back and check that too to make sure it works on the Mac. "View source" on my website would show the entire html page, but I've pulled the code from the body section to show here: carousel({id:'Photos', border:'', size_mode:'image', width:120, height:120, sides:8, steps:75, speed:4, direction:'left', images:['mainthumbs/babiesthumb.jpg','mainthumbs/engagementsthumb.jpg','mainthumbs/dancethumb1.jpg','mainthumbs/artistthumb.jpg','mainthumbs/portraitsthumb1.jpg','mainthumbs/seniorsthumb1.jpg','mainthumbs/wedthumb1.jpg'], links:['babies/babies.html','engagements/engagemainshow/engagementpictures.html','dance/dancepictures.html','artists/artists.html','portraits/portraits.html','seniors/highschoolseniors.html','weddings/weddings.html'], lnk_base:'', lnk_targets:['_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1', '_iframe1' ], lnk_attr:['width=200,height=300,top=200,menubar=yes', 'width=300,height=200,left=400,scrollbars=yes', 'width=150,height=250,left=200,top=100', ''], titles:['Babies', 'Engagements', 'Dance', 'Artists', 'Portraits', 'HS Seniors', 'Weddings'], image_border_width:1, image_border_color:'#E3F0A1' });   </div> Any thoughts? -Stuart

  • Preset value of HTML Forms - iPhone SDK

    - by laura
    Hi. I'm trying to preset the value of a dropdown menu and the value of a text box in an HTML form. As soon as the user taps the button in my iPhone app, it enters the webview and I was hoping to preset one of the dropdown menus and text field. How do I go about this? I want to set the dropdown to value "4" and the text field to "Giro Apps" Here's the relevant HTML form code: <select id="advSrcId" class="list" onchange="showOther($('advSrcId').options[$('advSrcId').selectedIndex].value)" name="advSrcId"> <option selected="" value="">Select</option> <option value="1">Google</option> <option value="2">Facebook</option> <option value="3">Friend Referral</option> <option value="4">Other</option> </select> <div id="otherAdvsrc" style=""> <p> Please give details here: <br/> <input class="text" type="text" value="" name="advsrc"/> <br/> </p> </div> TIA!

  • Circular Dependency of Navigation Control in iPhone

    - by Taimur Hamza
    Hi everyone , In my view this is one of the strangest problem i have ever come across in iPhone app development. Let me explain the scenario , i have main screen 'A' on which i have a Button that directs me to another Screen say 'B'. Now on Screen 'B' i have a feature in which user can send a mail to his friend for promotion purpose e.g a user wishes to tell a frnd about this app so i used MFMailComposeViewController and a view is generated where the user types the address and click send ( subject and body of mail is automatically generated ). After sending the mail a new view opens say screen 'C' and here i want to give the user the options . 1. Go to Screen 'A' ( which is main screen of the app ) 2. Go back to Screen 'B' ( from where the user requested to send a mail to his frnd ). Now the strange part i cannot declare the variables ( Screen 'A' and 'B' ) of both these files here at in header file of screen 'C' . Even when i declare the header file at the top it generates an error. The variables can be easily be declared and used for other screens but not for these 2 screens. Can anybody please explain wats the problem.? this the text of the error "/Users/admin/Documents/AppName/Classes/A.h:42: error: expected specifier-qualifier-list before 'B'" Thanks Guys ! Taimur

  • A problem with connected points and determining geometry figures based on points' location analysis

    - by StolePopov
    In school we have a really hard problem, and still no one from the students has solved it yet. Take a look at the picture below: http://d.imagehost.org/0422/mreza.gif That's a kind of a network of connected points, which doesn't end and each point has its own number representing it. Let say the numbers are like this: 1-23-456-78910-etc. etc.. (You can't see the number 5 or 8,9... on the picture but they are there and their position is obvious, the point in middle of 4 and 6 is 5 and so on). 1 is connected to 2 and 3, 2 is connected to 1,3,5 and 4 etc. The numbers 1-2-3 indicate they represent a triangle on the picture, but the numbers 1-4-6 do not because 4 is not directly connected with 6. Let's look at 2-3-4-5, that's a parallelogram (you know why), but 4-6-7-9 is NOT a parallelogram because the in this problem there's a rule which says all the sides must be equal for all the figures - triangles and parallelograms. Also there are hexagons, for ex. 4-5-7-9-13-12 is a hexagon - all sides must be equal here too. 12345 - that doesn't represent anything, so we ignore it. I think i explained the problem well. The actual problem which is given to us by using an input of numbers like above to determine if that's a triangle/parallelogram/hexagon(according to the described rules). For ex: 1 2 3 - triangle 11 13 24 26 -parallelogram 1 2 3 4 5 - nothing 11 23 13 25 - nothing 3 2 5 - triangle I was reading computational geometry in order to solve this, but i gave up quickly, nothing seems to help here. One friend told me this site so i decided to give it a try. If you have any ideas about how to solve this, please reply, you can use pseudo code or c++ whatever. Thank you very much.

  • TFS and Forms Authentication

    - by George
    I don't know squat about TFS, other than as a user who has performed simple check in/outs. I just installed it locally and would like to do joint development with a friend. I was having trouble making my TFS web site on port 8080 visible (the whole scoop is here if your interested) and I wonder if it could be related to the fact that TFS is probably using Windows Authentication to identify the user. Can TFS be set up to use forms authentication? We probably need to set up a VPN, though that's a learning curve too. To use TFS, do our machines have to belong to a domain? We're not admin types, though he is better than me, though I would be interested in any feedback or advice on which path is likely to pan out the best. I already got AxoSoft OneTime working in this type of an environment and it suits us well, but I am tempted at all the bells & whistles with TFS and the ability to tie tracked bug items to code changes. As far as finding a good way to share code, do sites like SourceForge allow one to keep code secure among members only?

  • Suggestions for a PHP programmer wanting to create a timer app for an internet cafe

    - by grokker
    Hi, I was asked by a friend to make a timer app for his small internet cafe. He wants to have timers on each client PCs. The timers indicate how much time has been spent by the customer. On the PC that he uses, there's another program that has the overview of all the timers and there's a button for each client PCs that allows him to blacken out the screen. It's not automatic hence the button. The problem is I haven't done any desktop apps before so that's why I'm asking you guys (the awesome people at SO) for suggestions/advice on what language/tool to use. A little info about me: I did Java but haven't tried Swing though. I know a bit about Python and Ruby too. I don't mind learning new languages as long as I get to finish or get a prototype up and running. He doesn't mind if I could show him a prototype, it's actually for me. It gives me satisfaction to see I'm progressing. I'm not planning on asking him to pay me for doing this. Whatever he gives me is fine. P.S. He's using Windows XP

  • How does a java web project architecture look like without EJB3 ?

    - by Hendrik
    A friend and I are building a fairly complex website based on java. (PHP would have been more obvious but we chose for java because the educational aspect of this project is important to us) We have already decided to use JSF (with richfaces) for the front end and JPA for the backend and so far we have decided not to use EJB3 for the business layer. The reason we've decided not to use EJB3 is because - and please correct me if I am wrong - if we use EJB3 we can only run it on a full blown java application server like jboss and if we don't use EJB3 we can still run it on a lightweight server like tomcat. We want to keep speed and cost of our future web server in mind. So far i've worked on two JEE projects and both used the full stack with web business logic factories/persistence service entities with every layer a seperate module. Now here is my question, if you dont use EJB3 in the business logic layer. What does the layer look like? Please tell what is common practice when developing java web projects without ejb3? Do you think business logic layer can be thrown out altogether and have business logic in the backing beans? If you keep the layer, do you have all business methods static? Or do you initialize each business class as needed in the backing beans in every session as needed?

  • Intelligent web features, algorithms (people you may follow, similar to you ...)

    - by hilal
    I have 3 main questions about the algorithms in intelligent web (web 2.0) Here the book I'm reading http://www.amazon.com/Algorithms-Intelligent-Web-Haralambos-Marmanis/dp/1933988665 and I want to learn the algorithms in deeper 1. People You may follow (Twitter) How can one determine the nearest result to my requests ? Data mining? which algorithms? 2. How you’re connected feature (Linkedin) Simply algorithm works like that. It draws the path between two nodes let say between Me and the other person is C. Me - A, B - A connections - C . It is not any brute force algorithms or any other like graph algorithms :) 3. Similar to you (Twitter, Facebook) This algorithms is similar to 1. Does it simply work the max(count) friend in common (facebook) or the max(count) follower in Twitter? or any other algorithms they implement? I think the second part is true because running the loop dict{count, person} for person in contacts: dict.add(count(common(person))) return dict(max) is a silly act in every refreshing page. 4. Did you mean (Google) I know that they may implement it with phonetic algorithm http://en.wikipedia.org/wiki/Phonetic_algorithm simply soundex http://en.wikipedia.org/wiki/Soundex and here is the Google VP of Engineering and CIO Douglas Merrill speak http://www.youtube.com/watch?v=syKY8CrHkck#t=22m03s What about first 3 questions? Any ideas are welcome ! Thanks

  • WPF Spellcheck Engine takes up too much memory.

    - by Matt H.
    Each datatemplate in my WPF ItemsControl contains FIVE custom bindable richtextbox controls. It is a data-driven app that for authoring multiple-choice questions -- The question and four answer choices must all support: 1) Spell check 2) Rich formatting (otherwise I'd use regular textboxes) The spell check object in .NET 4 has a Friend constructor that takes a single argument of owner As TextBoxBase This means every richtextbox in the ItemsControl has 5 Spellcheck objects! This is the problem -- every spell check engine is consuming about 500k memory. So after you favor in the spellcheck, bindings, additional controls in the DataTemplate, etc.. a single multi choice question consumes more than 3MB memory. Users with 100--200 questions will quickly see the App raise it's memory consumption to 500+ MB. Management is definitely not OK with this. Is there a way to minimimze this problem? The best suggestion I've heard is to enable/disable spellcheck if the richtextbox is in the ItemsControl's scrollviewer: I haven't gotten an answer to how to go about it: (http://stackoverflow.com/questions/2869012/possible-to-implement-an-isviewportvisible-dependencyproperty-for-an-item-in-an-i) Any good ideas?

    Hi there, I am working on a blog for my friend. I want to gift him the blog on his birthday. Just for some fun I want to restrict access to the blog. e.g. The website. www.myfriend.com opens with a splash screen. The screen has his picture and a question regarding him. these questions can be. If you know me.... What is my nickname? Whats my fav. sport? etc etc This restriction should not be based on the default user management offered by Wordpress and should involve a simple answer to a question which is randomly generated from list of questions once the visior gives a correct answer the page redirects to the blog please note even if the user types www.myfriend.com/blog they should be able to see it. this restriction is not a restriction in true sense but just involves some user interaction. Its just for fun but adds a bit of spice. Much appreciated. Thanks.

  • Wordpress Rewrite Redirect Failure

    - by Rory Hart
    I'm helping a friend recover from the mess outsourcing a wordpress website caused him (mistake #1) and I have this weird error. The hosting he is using appears to be redirecting www.domain.com to domain.com (NFI why) automatically which works fine in every browser except IE (i know right!). So adding the first redirect fixed that, until I added the permalink redirect. Now when IE goes to an old wordpress link like http://www.domain.com/?p=520 the redirect fails. RewriteEngine On RewriteBase / # Rewrite rule for wierd redirect issue RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^/?(.*)$ "http\:\/\/doman\.com\/$1" [R=301,L] # Rewrite Rule for Wordress Permalinks RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] I tested this out with wget and it complains: ERROR: Redirection (301) without location. So it seems likely that IE is suffering from the same error (without the helpful error message). But I haven't a clue how to fix it. I am hoping that he will switch hosting companies but we will see. In the meantime any ideas?

  • Why does this cast to Base class in virtual function give a segmentation fault?

    - by dehmann
    I want to print out a derived class using the operator<<. When I print the derived class, I want to first print its base and then its own content. But I ran into some trouble (see segfault below): class Base { public: friend std::ostream& operator<<(std::ostream&, const Base&); virtual void Print(std::ostream& out) const { out << "BASE!"; } }; std::ostream& operator<<(std::ostream& out, const Base& b) { b.Print(out); return out; } class Derived : public Base { public: virtual void Print(std::ostream& out) const { out << "My base: "; //((const Base*)this)->Print(out); // infinite, calls this fct recursively //((Base*)this)->Print(out); // segfault (from infinite loop?) ((Base)*this).Print(out); // OK out << " ... and myself."; } }; int main(int argc, char** argv){ Derived d; std::cout << d; return 0; } Why can't I cast in one of these ways? ((const Base*)this)->Print(out); // infinite, calls this fct recursively ((Base*)this)->Print(out); // segfault (from infinite loop?)

  • Facebook and retrieving a users "wall"

    - by Neurofluxation
    I have been given the dubious task of working with the Facebook API. I have managed to get quite far with all the little bits and pieces (bringing in "fan pages" and "friend lists"). However, I cannot seem to import a users wall into my App using SOLELY Javascript. I have this code to bring in the users friends: var widget_div = document.getElementById("profile_pics"); FB.ensureInit(function () { FB.Facebook.get_sessionState().waitUntilReady(function() { FB.Facebook.apiClient.friends_get(null, function(result) { var markup = ""; var num_friends = result ? Math.min(100, result.length) : 0; if (num_friends > 0) { for (var i=0; i<num_friends; i++) { markup += "<div align='left' class='commented' style='background-color: #fffbcd; border: 1px solid #9d9b80; padding: 0px 10px 0px 0px; margin-bottom: 5px; width: 75%; height: 50px; font-size: 16px;'><fb:profile-pic size='square' uid='"+result[i]+"' facebook-logo='true'></fb:profile-pic><div style='float: right; padding-top: 15px;'><fb:name uid='"+result[i]+"'></fb:name></div></div>"; } } widget_div.innerHTML = markup; FB.XFBML.Host.parseDomElement(widget_div); }); }); }); /*******YOUR FRIENDS******/ FB.XFBML.Host.parseDomTree(); Any idea whether I can change this to retrieve the Walls? Thanks in advance you great people! ^_^

  • Flash CS5- Problem with "navigateToURL" in web-browswer hosted on MySpace

    - by NervXT
    I made a quick flash document for my friend who posted it his MySpace. The document has 3 buttons, each with a URL attached to them. When I play the SWF file locally, the links work fine, however once it's published to MySpace, the links refuse to work. The hand icon comes up so it understands them at least as buttons, but it seems to do nothing when clicked in the web-browser. Also, I can open the SWF in my browser and it also works fine. I'm using Flash CS5 and working in ActionScript 3.0. The three buttons are on one layer called "Buttons". I right click the button and click "Actions". From there, I click the "Code Snippets" and under the folder "Actions" there is an item called "Click to Go To Webpage". Here is the code it gives you by default: button_2.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage_6); function fl_ClickToGoToWebPage_6(event:MouseEvent):void { navigateToURL(new URLRequest("http://www.adobe.com"), "_blank"); } I heard there was a problem with MySpace not allowing action scripts, but after checking the source code of the web-page, the values in the "param" code seem to "always" allow action scripts. At any point, I'm lost and not sure what it causing this. I don't think it's a browser issue, since it's working fine when I execute the SWF by itself, and when I load it into Firefox. It's just seems MySpace is having a problem with it. Any advice is appreciated.

  • A UnicodeDecodeError that occurs with json in python on Windows, but not Mac.

    - by ventolin
    On windows, I have the following problem: >>> string = "Don´t Forget To Breathe" >>> import json,os,codecs >>> f = codecs.open("C:\\temp.txt","w","UTF-8") >>> json.dump(string,f) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python26\lib\json\__init__.py", line 180, in dump for chunk in iterable: File "C:\Python26\lib\json\encoder.py", line 294, in _iterencode yield encoder(o) UnicodeDecodeError: 'utf8' codec can't decode bytes in position 3-5: invalid data (Notice the non-ascii apostrophe in the string.) However, my friend, on his mac (also using python2.6), can run through this like a breeze: > string = "Don´t Forget To Breathe" > import json,os,codecs > f = codecs.open("/tmp/temp.txt","w","UTF-8") > json.dump(string,f) > f.close(); open('/tmp/temp.txt').read() '"Don\\u00b4t Forget To Breathe"' Why is this? I've also tried using UTF-16 and UTF-32 with json and codecs, but to no avail.
