  • VideoView Not Playing, Error(1,-1)

    - by Jesse J
    I originally thought that the video format was wrong, but after trying .mov, .3gp, and .mp4 with H.264, I'm wondering if something is wrong with my code? public class IntroActivity extends Activity { VideoView videoHolder; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override protected void onStart() { getWindow().setFormat(PixelFormat.TRANSLUCENT); videoHolder = new VideoView(this); //videoHolder = (VideoView)findViewById(R.id.myvideoview); Uri video = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.menu); videoHolder.setVideoURI(video); videoHolder.start(); videoHolder.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { public void onCompletion(MediaPlayer mp) { videoHolder.start(); } }); setContentView(videoHolder); super.onStart(); }

  • Android App crashing on one device only

    - by Daniel1402
    I am working on a new game that works perfectly on my test devices, 7-inch tablets and smartphones. But it crashes on my Galaxy Tab2 10-inch tablet with an Out of memory error. It always crashes when I start to play a second game! I have spent a full week checking the codes and I cannot figure out what is wrong. When I play from the menu screen, everything works fine. When I want to replay a game level from the level screen, the game will crash on the second launch. The level screen is made of 3 fragments, each with 32 buttons (4kB in size). I tried to keep only one fragment in memory with viewPager.setOffscreenPageLimit(1); but it does not solve the problem. Could someone stir me in some direction as to where to look for the potential problem? Why is the 10-inch tablet the only one to crash? Thanks.

  • What advantage does Monad give us over an Applicative?

    - by arrowdodger
    I've read this article, but didn't understand last section. The author says that Monad gives us context sensitivity, but it's possible to achieve the same result using only an Applicative instance: let maybeAge = (\futureYear birthYear -> if futureYear < birthYear then yearDiff birthYear futureYear else yearDiff futureYear birthYear) <$> (readMay futureYearString) <*> (readMay birthYearString) It's uglier for sure, but beside that I don't see why we need Monad. Can anyone clear this up for me?

  • What is an appropriate way to programmatically exit an application?

    - by denchr
    I am evaluating user inputs as commands for my application. If the user presses Q, or q, and then hits enter, the application quits and execution terminates. Is there a proper context, or best practices on how to do that? I do not have any resources to release, or anything like that. Should I just use System.exit(0);? Is there a recommended way to do that? As my first approach I do something like this: while (true){ try{ BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); //Other logic goes here... if (br.readLine().equalsIgnoreCase("Q")){ System.exit(0); } } catch (IOException ioe) { System.out.println("IO error trying to read your selection"); } }

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • Calling Javascript after linking to another page

    - by kratos2488
    I am doing an integration with a support system (Helpstream) and I am currently working on doing some in-app context sensitive help. I have put in a link that will send the user to a section of Helpstream that will allow them to ask a question. Problem is, there are buttons on the page that call Javascript that will bring up a lightbox where the user fills out a form to submit a question. What I need to do is have that form come up after the user goes through the link, so essentially run the Javascript once the user hits the page. The call that I have to implement is NewTopic.CreateNew({type:"Question"}) Any tips would be greatly appreciated. Thanks in advance.

  • Key Events in TabActivities?

    - by stormin986
    I have a TabActivity and want to catch and handle presses of HOME and BACK. Where do I need to catch these events? In my subclass of TabActivity I implement the following: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { // Code handling } return super.onKeyDown(keyCode, event); } Didn't work. So I placed a breakpoint on the switch statement line. But this function never gets called, whether I press volume up/down, menu, home, or back. Where do I need to catch these KeyEvents?

  • Get current user from View

    - by gosu kiwi
    So what I want to do is, in my main layout, have a menu for logged in users, and a different for anon users. THe layout will be used on every page, so I'm not sure how to do this, as I've seen, the Auth Component can only be used in the controller, this would be nice if I had to do this in only one view, but for every view, how can I do this? Do I have to do something on AppController? What I want to do is basically // layout <?php if(logged): ?> Welcome <?php echo $user; ?> <?php else: ?> Welcom anon, Log in? <?php endif; ?>

  • Continue Drupal processing after page send.

    - by David
    I need to do some additional processing after a Drupal page has been sent. I know I could fire a background shell command, but I need the current Drupal execution context to be maintained. I've spent a lot of time looking, but I can't find any documentation in this regard. This is surprising because it must surely be a common requirement. The only real idea I have is to fire up Drupal (again) via a shell command (exec, etc) and supply it with a pseudo path which would invoke the continued processing. But this seems unnecessarily complex/wasteful. Any pointers greatly appreciated, tks.

  • Can JQuery/JavaScript be used to write a substantial client side application?

    - by Ian
    I have an unusual situation - I have an embedded video streaming device with a complicated UI, and I need to use an embedded web server to reproduce that UI through a web browser. I'm thinking of using JavaScript/JQuery on a C++ backend (I am NOT coding all this myself, I need to hire people for the grunt work). The embedded web server is much less powerful than a PC, so I want to write an application that runs the entire UI in the browser, and only communicates with the server to pass new program settings back and forth, get status updates from the device, and control video playback. In other words, the client gets one big page or a small number of big pages (effectively downloading the application), the application maintains significant local memory storage, and once the pages are first loaded the server never sends anything layout-related. The application has two rows of tabs to navigate ~40 menu pages, drag-and-select controls to pick cells in a grid, sorted lists, lots of standard data entry options, and it should be able to control up to 16 embedded video players at once (preferably VLC). Is this possible in JavaScript/JQuery with a C++ backend?

  • Comparing an array of users to an array of structs with user object as attribute, and returning matc

    - by keruilin
    I have an array of users who are friends. Let us call this array: friends I then have an array of structs. Each struct has a user object as an attribute (it also has a rank attribute). Here's what the struct class looks like, to add some context: class Leader < Struct.new(:rank, :user); end Let us call this array of structs: all_leaders_plus_rank I want to compare friends and all_leaders_plus_rank, and add the match from all_leaders_plus_rank to a new array of structs called friendly_leaders.

  • How to find the submit button in a specific form in jQuery

    - by leifg
    I try to get jQuery object of a submit button in a specific form (there are several forms on the same page). I managed to get the form element itself. It looks something like this: var curForm = curElement.parents("form"); The current Element has the context HTMLInputElement. The several techniques I tried to get the according submit element of the form: var curSubmit = curForm.find("input[type='submit']"); var curSubmit = $(curForm).find("input[type='submit']"); var curSubmit = curForm.find(":submit"); var curSubmit = $(curForm).find(":submit"); var curSubmit = $(curSubmit, "input[type='submit']"); the result is always the same (and very strange). The result that I get is the same element as "curElement". So how can I get the right submit button?

  • Singelton restricted to instance of dll

    - by codeySmurf
    If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

  • Mercurial and particular files branching

    - by zerkms
    The context: i have a project, that contains configs/ directory, which contains (surprise-surprise!) a set of config files: database.php, facebook.php, twitter.php, cache.php, etc What I did in svn: I have created branches per specific file and made changes there (changed database connections, facebook API keys, etc). So they were stored in my private branch. Now I'm trying to migrate to "modern" nowadays DSCM - Mercurial. And I cannot get any possibility of doing the same. Any ideas?

  • living column in instruments

    - by dubbeat
    In the context of allocations what exactly does the living column mean? Does it mean the number of times an object was created or does it mean how many instances of an object there is? I ask because I'm testing going in and out of a view. When I enter the view I create a class "myClass". When I exit the view I nil "myClass" and release it. If I go in and out of the view 6 times for example the living column in instruments for "myClass" says 6. Is this normal or is it not being released properly?

  • How to restart Linux from inside a C++ program?

    - by Dave K
    I have a Qt 4 GUI where I need to have a option in a drop-down menu that allows the user to choose to restart the computer. I realize this might seem redunant with the ability to restart the computer in other ways, but the choice needs to stay there. I've tried using system() to call the following: a suid-root shell script a non-suid shell script a suid-root binary program and all of them just cause reboot: must be superuser to be printed. Using system() to call reboot directly does the same thing. I'm not especially attached to using system() to do this, but it seemed like the most direct choice. How can I reboot the system from the GUI?

  • Silently binding a variable instance to a class in C++?

    - by gct
    So I've got a plugin-based system I'm writing. Users can create a child class of a Plugin class and then it will be loaded at runtime and integrated with the rest of the system. When a Plugin is run from the system, it's run in the context of a group of plugins, which I call a Session. My problem is that inside the user plugins, two streaming classes called pf_ostream and pf_istream can be used to read/write data to the system. I'd like to bind the plugin instance's session variable to pf_ostream and pf_istream somehow so that when the user instantiates those classes, it's already bound to the session for them (basically I don't want them to see the session internals) I could just do this with a macro, wrapping a call to the constructor like: #define MAKE_OSTREAM = pf_ostream_int(this->session) But I thought there might be a better way. I looked at using a nested class inside Plugin wrapping pf_ostream but it appears nested classes don't get access to the enclosing classes variables in a closure sort of way. Does anyone know of a neat way to do this?

  • PXE boot windows versions

    - by iJonathan
    I will make a PXE-server on Ubuntu for the installations of Windows XP and 7. When a computer starts from the network, then it should be display a menu with, for example "installation of XP" and the next item "installation of 7". When I select one of these items, the installation must start. I won't use an image, wds or FOG because the computers aren't the same and there a different departments in the company with a different configuration, programs etc. Neither Windows Server, only an Ubuntu PXE-server How I should start with making that? Thanks.

  • Why is Django sending the wrong email template?

    - by Mark
    I'm so baffled... I keep staring at this code, looking for the typo, but I can't find it! template = 'emails/transporter_joined' tt = loader.get_template(template+'.txt') c = Context({'user':user, 'fee': settings.FEE * Decimal('100.00'),'settings':settings}) e = EmailMultiAlternatives('Activate Your Account', tt.render(c), '[email protected]', [user.email]) try: ht = loader.get_template(template+'.html') e.attach_alternative(ht.render(c), 'text/html') except: pass e.send() First it should load the 'emails/transporter_joined.txt' template, and adds that to the email. And then it tries to load a '.html' version and attaches that too. In Gmail you can see the the "original email" with both emails, and all the headers in plain text. It very clearly shows the .txt version twice. the .html and .txt files are definitely different. What am I doing wrong here? If I replace this tt = loader.get_template(template+'.txt') With .html instead, then it sends the .html twice... it must be Django that's screwing up, no?

  • How can I Include Multiples Tables in my linq to entities eager loading using mvc4 C#

    - by EBENEZER CURVELLO
    I have 6 classes and I try to use linq to Entities to get the SiglaUF information of the last deeper table (in the view - MVC). The problem is I receive the following error: "The ObjectContext instance has been disposed and can no longer be used for operations that require a connection." The view is like that: > @model IEnumerable<DiskPizzaDelivery.Models.EnderecoCliente> > @foreach (var item in Model) { > @Html.DisplayFor(modelItem => item.CEP.Cidade.UF.SiglaUF) > } The query that i use: var cliente = context.Clientes .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); The question is: How Can I improve this query to pre loading (eager loading) "Cidade" and "UF"? See below the classes: public partial class Cliente { [Key] [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] public int IdCliente { get; set; } public string Email { get; set; } public string Senha { get; set; } public virtual ICollection<EnderecoCliente> Enderecos { get; set; } } public partial class EnderecoCliente { public int IdEndereco { get; set; } public int IdCliente { get; set; } public string CEPEndereco { get; set; } public string Numero { get; set; } public string Complemento { get; set; } public string PontoReferencia { get; set; } public virtual Cliente Cliente { get; set; } public virtual CEP CEP { get; set; } } public partial class CEP { public string CodCep { get; set; } public string Tipo_Logradouro { get; set; } public string Logradouro { get; set; } public string Bairro { get; set; } public int CodigoUF { get; set; } public int CodigoCidade { get; set; } public virtual Cidade Cidade { get; set; } } public partial class Cidade { public int CodigoCidade { get; set; } public string NomeCidade { get; set; } public int CodigoUF { get; set; } public virtual ICollection<CEP> CEPs { get; set; } public virtual UF UF { get; set; } public virtual ICollection<UF> UFs { get; set; } } public partial class UF { public int CodigoUF { get; set; } public string SiglaUF { get; set; } public string NomeUF { get; set; } public int CodigoCidadeCapital { get; set; } public virtual ICollection<Cidade> Cidades { get; set; } public virtual Cidade Cidade { get; set; } } var cliente = context.Clientes .Where(c => c.Email == email) .Where(c => c.Senha == senha) .Include(e => e.Enderecos) .Include(e1 => e1.Enderecos.Select(cep => cep.CEP)) .SingleOrDefault(); Thanks!
