  • Video loads but doesn't play with MPMoviePlayerController in iPad

    - by hgpc
    I'm using MPMoviePlayerController to play videos in an iPad app. Everything works well on the iPad simulator. On an actual device, the videos load but don't play, even if I press the play button. I can move the slider and see different frames of the video, but it never plays. I'm using the following code: moviePlayer = [[MPMoviePlayerController alloc] init]; moviePlayer.shouldAutoplay = YES; moviePlayer.contentURL = video.urlVideo; moviePlayer.view.frame = videoPlayerContainer.bounds; moviePlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [videoPlayerContainer addSubview:moviePlayer.view]; moviePlayer.controlStyle = MPMovieControlStyleEmbedded; [moviePlayer play]; Help?

  • Setting background views depending on user settings

    - by munchine
    I've got an app where the background needs to be set depending on user preference. The user can change this at any time via settings tab. I've got it working by checking NSUserDefaults in viewWillAppear and setting self.view.backgroundColor. This is really clunky. The right approach (I thought) is to set the background in the root view and for every views that gets on the stack inherit the background. So in viewDidLoad, I've got self.view.backgroundColor = [UIColor clearColor]; I would have thought this should work. But all I get is a clear background. Any guidance is greatly appreciated.

  • StringLengthValidator - localization not working

    - by danysdragons
    I am validating input to my ASP.NET application using StringLengthValidators, and using the ValidationSummary control to display the error messages. To localize the application, the StringLengthValidators have the MessageTemplateResourceName and MessageTemplateResourceType attributes set. The first time the validator runs, it picks up the correct error message based on the current culture setting. If I change the language setting while running the app, the next time the validator runs, the ValidationSummary it still displays the error message for the old culture. The text for all other controls is being updated correctly. Any ideas, folks?

  • lwjgl applets 101: How can I write them?

    - by Vuntic
    I have a working app in lwjgl. It doesn't do much yet; I've just started, but it does compile and run like it's supposed to. I want to make it into an applet. I've followed the guide here, and I have an applet that runs nicely and displays text and such in the applet area and can access the functions of lwjgl (like Sys.alert), but I can't figure out how to get opengl to actually render. I've tried extending an AWTGLCanvas and calling this.add(myAWTGLCanvas), where this is the Applet that I'm using, but... nothing. The initGL() and paintGL() methods never get called. I wonder if I'm supposed to be doing something with Display, but that's not for applets, right? Help? Also: This counts as a "beginner" question, right?

  • Configurable UI Plugin frameworks for .NET Compact Framework

    - by Andy White
    Is anyone aware of any frameworks for configuring UIs and possibly plugins for .NET Compact Framework (rich client) applications? Ideally, I'm hoping to find something that would allow you to bascially configure an application's UI and screenflow via an XML file, or some other configuration mechanism, and allow you to plugin different "Action" classes to take care of specific events, etc. in the app. We basically want to have a base application, which allows you to plugin specific/custom functionality to support different customers. I know it's a lot to find, but feel free to throw out any frameworks that might support any or all of these types of things.

  • CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

    - by Rasiel
    I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

  • Splitting android application in to two 'branches', free and paid.

    - by Alxandr
    I've developed an android-application that I'dd like to put up on the marketplace. However, I want to split it into two separate applications, one free (with ads), and one paid (logically without ads). How would I go about doing that? I'm not wondering about adding ads (I've alreaddy managed that), but how to take one existing android-application (eclipse-project) and split it into two without having to create a new project and just copy-paste every file one by one (or in batch for that matter). Is that possible? Btw, I use GIT for SCM, so I've made two separate branches, one master and one free, but I need to set some cind of config-value that makes shure that the market separates them as two different applications. Also, when a user 'upgrades', is it possible to copy the db from the free app to the paid one?

  • GetWindowPlacement/SetWindowPlacement not working in WinForms for high DPI

    - by RandomEngy
    I've got a legacy WinForms app and I want to save the window position and size across sessions. I've been using GetWindowPlacement and SetWindowPlacement during the FormClosing and Load events. The problem I'm getting is that at higher DPI settings (Such as Medium, size at 125%) the sizes keep inflating. I'll call SetWindowPlacement on it with a certain size, but when GetWindowPlacement is called, those numbers come back 25% bigger, even though the window was the same size all along. The same sort of problem exists when saving the size of a resizable element within the form. Now this works fine if I create a new WinForms project: The size stays stable even when running at the higher DPI. I'm guessing there's some legacy setting in the bowels of the project or some arcane Form setting that's messing it up, but I can't find out where. I've called IsProcessDPIAware on both projects and both are true. Does anyone know what might be causing this?

  • New Facebook FQL table vs. Grap API

    - by PanosJee
    Hello everyone I just read the new User fql table fields at http://developers.facebook.com/docs/reference/fql/user As I can see a lot of the fields have been deprecated such as work_history or books and movies. It is quite essential for my app to get all those fields for my user's friends in a single fql query. If i am not wrong the only way to do this is to get those extra fields using the Graph API by requesting them seperately for every friend of my user. Is there any way to do it in a more efficient way without so many calls? Can I subscribe to real time updates for the request fields for my user's friends (i do not care about the logged in user data)? Thank you a lot

  • MKMapView doesn't want to call didAddAnnotationViews method

    - by TheLearner
    I am writing a little map kit app but it doesn't want to call the delegate method didaddannotationviews: (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views { //Get the first MKAnnotationView from the views returned MKAnnotationView *annotationView = [views objectAtIndex:0]; //Get the annotation from the first annotation view and save it in a variable which can hold any object as long as it implements mkannotation id <MKAnnotation> mp = [annotationView annotation]; //Create a region MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance([mp coordinate], 250, 250); //As the mapview to animate i.e. display the region [mv setRegion:region animated:YES]; } @interface WhereAmIAppDelegate : NSObject { UIWindow *window; CLLocationManager *locationManager; IBOutlet MKMapView *mapView; IBOutlet UIActivityIndicatorView *activityIndicator; IBOutlet UITextField *locationTitleField; }

  • MFMailComposeViewController: how to get notified when view appears?

    - by Karsten Silz
    In my app, users can take a picture with the camera or pick one from the library and email it as an attachment. I use the MFMailComposeViewController for seamless email. On my iPhone 3GS, it takes about 5-7 seconds for the email view to appear with the attachment. Now I want to show a progress indicator view when the user pushes the "Send" button and hide that view when the email view comes up. The problem is that the MFMailComposeViewController delegate only calls when the email sending is done. Can I get notified somehow when the email window appears on the screen?

  • Rails Oauth Desktop Plugins

    - by Ryan
    I am creating a rails application that I also wish to work as a native app on the iPhone and Android. In order to facilitate this, I was thinking about becoming an OAuth provider. Is there a rails OAuth plugin that will work like this, or is there a better solution to protect the API? Note: I have found pelle's OAuth plugin, and it looks very robust, but it looks like it requires a callback URI, which the native apps would not have. Is it possible to just convert this over without much trouble?

  • Differences between AForge and OpenCV

    - by vrish88
    Hello, I am just learning about computer vision and C#. It seems like two prominent image processing libraries are OpenCV and AForge. What are some of the differences of the two? I am making a basic image editor in C# and while researching I have come across articles on both. But I don't really know why I would choose one over the other. I would like to eventually improve the app to include more advanced functions. Thanks.

  • Transition domain to new web host without waiting for DNS propagation

    - by jcmoney
    I was considering switching to Amazon EC2 to host my website to handle more traffic. It seems like I would have to update DNS records to point to the new server but I was wondering if there was a way to avoid having to wait for the new DNS record to propagate. Putting the code on both hosts would not work for me since the app writes to a database pretty frequently. I thought about just using a meta redirect or php redirect on the old host to redirect to the new host ip but was wondering if there's a better more accepted way of doing this.

  • Progressive download using Matt Gallagher's audio streamer

    - by Fernando Valente
    I'm a completely n00b when talking about audio. I'm using Matt Gallagher's audio streamer on my radio app. How may I use progressive download? Also, ExtAudioFile is a good idea too :) Edit: Used this: length = CFReadStreamRead(stream, bytes, kAQDefaultBufSize); if(!data) data =[[NSMutableData alloc] initWithLength:0]; [data appendData:[NSData dataWithBytes:bytes length:kAQDefaultBufSize]]; Now I can save the audio data using writeToFile:atomically: NSData method, but the audio won't play. Also, if I try to load it on a AVAudioPlayer, I get an error.

  • Serialize struct with pointers to NSData

    - by leolobato
    Hey guys, I need to add some kind of archiving functionality to a Objective-C Trie implementation (NDTrie on github), but I have very little experience with C and it's data structures. struct trieNode { NSUInteger key; NSUInteger count, size; id object; __strong struct trieNode ** children; __strong struct trieNode * parent; }; @interface NDTrie (Private) - (struct trieNode*)root; @end What I need is to create an NSData with the tree structure from that root - or serialize/deserialize the whole tree some other way (conforming to NSCoding?), but I have no clue how to work with NSData and a C struct containing pointers. Performance on deserializing the resulting object would be crucial, as this is an iPhone project and I will need to load it in the background every time the app starts. What would be the best way to achieve this? Thanks!

  • iPhone UIWebView width does not fit after zooming operation + UIInterfaceOrientation change

    - by choonkeat
    I created a bare bones iPhone app with a UIWebView (Scales Page to Fit = YES, shouldAutorotateToInterfaceOrientation = YES) and loaded a webpage, e.g. http://stackoverflow.com/ Rotating the device shows that UIWebView is auto-resized to fit the width. Good. Incorrect: Zoom into the page and zoom out. Now rotating the device shows UIWebView in a weird width in one of the orientation (if u zoom in landscape, the portrait width is weird, vice versa). This behavior is fixed only when you navigate to another page. Correct: Load the same URL in Mobile Safari. Rotating works & the width fits regardless of the zooming exercise. Is this a UIWebView bug (probably not)? Or is there something that needs to be done to make things "just work" like in Mobile Safari?

  • HTTPHeaders Added to Downloaded File - CocoaHTTPServer???

    - by Don
    In an iPhone app where I use cocoahttpserver and take a sqlite database file from the iPhone and download it with a browser to my PC, when I look at the downloaded file using TextEdit, I see the text (below) at the end of the file. This text has apparently no effect on use of the database file, but I would prefer to not add stuff to the database file at all. Any ideas where this header info is coming from in cocoahttpserver and how to stop it? Thanks. ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.x" 26 ------WebKitFormBoundary3RAcT2SVGhGPnoA6 Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.x" 30 ------WebKitFormBoundary001Quvx6Efgaf23y Content-Disposition: form-data; name="submit.y" 12 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.x" 52 ------WebKitFormBoundaryfHyUUs1p31kBJ3gA Content-Disposition: form-data; name="submit.y" 9

  • Select row After UIPickerView is loaded

    - by Steve Gibson
    I have an iphone database app that loads a UIPickerView with data from a table. I want to set the selected row to a particular row from the data in another table. for example: Lets say I have a UIPickerView that is loaded with X number of names of the iPhone users friends (the number of names is variable, could be 1 or 1000 and all are entered into the DB by the user). The iPhone user has a preference set that their current best friend is TED. I want the UIPickerView to be position to TED when displayed. Where do I call selectRow? I tried in viewDidAppear but it was never called, in titleForRow which caused all kinds of strange behavior. viewDidLoad and viewWillAppear are out of the question because I don't know what's in the datasource to the picker yet. Thanks in advance.

  • Windows Workflow Foundation 4.0 and WCF web service faults (soap fault)

    - by Lygpt
    In my Workflow Foundation 4.0 RC app I have a 'Receive' and 'SendReplyToReceive' WCF messaging pair that work fine with a simple request/response operation, but I'm having trouble attempting to perform validation on the request and reply with a fault. In WCF I am able to create a throw custom fault contracts (which in turn sent out SOAP faults) but I just can't see how to achieve this with the built-in workflow messaging activities. I can only seem to response with a data transfer object (I'm not even able to respond with a choice of object). Any ideas? (Can you save my day yet again Maurice!?) Thanks!

  • Building an automatic web crawler

    - by Sakin
    I am building a web application crawler that's meant not only to find all the links or pages in a web application, but also perform all the allowed actions in the app (such as pushing buttons, filling forms, notice changes in the DOM even if they did not trigger a request etc.) Basically, this is a kind of "browser simulator". I find WebKit a good option to implement my crawler, since it has all the needed technology (Javascript engine, parsers, DOM manipulation, etc.) but it seems kind of an overkill being a fully featured browser. Is there any toolkit you know that can provide the above functionality?

  • reporting services: use a custom assembly with a local (RDLC) report

    - by JMarsch
    Hello: I am designing a report that will be used in local mode (an RDLC file) in a Winform app. I have a custom assembly with a static class that has some functions that I want to use inside of the report (as expressions). I have found all sorts of help for doing this with RDL reports, but I'm running into a permissions problem with my RDLC report. I get the following error at runtime: "The report references the code module (my module), which is not a trusted assembly". I know that this is some kind of a code security issue, but I'm not sure what to do to fix it. The documentation that I have seen online is aimed at RDL reports, and it instructs me to edit a SQL Server-specific policy file. I'm using RDLC, so there is no sql server involved. What do I need to do to acquire the appropriate permissions?

  • Visual C#, Large Arrays, and LOH Fragmentation. What is the accepted convention?

    - by Gorchestopher H
    I have an other active question HERE regarding some hopeless memory issues that possibly involve LOH Fragmentation among possibly other unknowns. What my question now is, what is the accepted way of doing things? If my app needs to be done in Visual C#, and needs to deal with large arrays to the tune of int[4000000], how can I not be doomed by the garbage collector's refusal to deal with the LOH? It would seem that I am forced to make any large arrays global, and never use the word "new" around any of them. So, I'm left with ungraceful global arrays with "maxindex" variables instead of neatly sized arrays that get passed around by functions. I've always been told that this was bad practice. What alternative is there? Is there some kind of function to the tune of System.GC.CollectLOH("Seriously") ? Are there possibly some way to outsource garbage collection to something other than System.GC? Anyway, what are the generally accepted rules for dealing with large (85Kb) variables?

  • Best Geocoding Service for iPhone Developers

    - by ckrames1234
    I have made an app that gets an array of addresses from a web service and I want to map them. I know Apple left this out in MapKit, including only a reverse GeoCoder. I was wondering what the best way to approach this problem was. Web Service? Google Maps API (How do API keys work?)? CloudMade? What is your opinions on which service is fastest, easiest to use, and cheapest (hopefully free)? Thanks, Conrad Kramer
