  • Safari Extension Questions

    - by Rob Wilkerson
    I'm in the process of building my first Safari extension--a very simple one--but I've run into a couple of problems. The extension boils down to a single, injected script that attempts to bypass the native feed handler and redirect to an http:// URI. My issues so far are twofold: The "whitelist" isn't working the way I'd expect. Since all feeds are shown under the "feed://" protocol, I've tried to capture that in the whitelist as "feed://*/*" (with nothing in the blacklist), but I end up in a request loop that I can't understand. If I set blacklist values of "http://*/*" and "https://*/*", everything works as expected. I can't figure out how to access my settings from my injected script. The script creates a beforeload event handler, but can't access my settings using the safari.extension.settings path indicated in the documentation. I haven't found anything in Apple's documentation to indicate that settings shouldn't be available from my script. Since extensions are such a new feature, even Google returns limited relevant results and most of those are from the official documentation. What am I missing? Thanks.

  • Setting article properties for a publication using RMO in C# .NET

    - by Pavan Kumar
    I am using transaction replication with push subscription. I am developing a UI for replication using RMO in C#.NET between different instances of the same database within same machine holding similar schema and structure. I am using Single subscriber and multiple publisher topology. During creation of publication i want to set a few article properties such as Keep the existing object unchanged ,allow schema changes at subscriber to false a,copy foriegn key constarint and copy check constraints to true. How do i set the article properties using RMO in C# .NET. I am using Visual Studio 2008 SP1.I also want to know as how we can select all the objects including Tables,Views,Stored Procedures for publishing at one stretch. I could do it for one table but i want to select all the tables at one stretch. This is the code snippet i used for selecting single table for publishing. TransArticle ta = new TransArticle(); ta.Name = "Article_1"; ta.PublicationName = "TransReplication_DB2"; ta.DatabaseName = "DB2"; ta.SourceObjectName = "person"; ta.SourceObjectOwner = "dbo"; ta.ConnectionContext = conn; ta.Create();

  • Monotouch.dialog and story board apps?

    - by Robin Diederen
    I'm trying to use mt.d; I've "drawn" an app using the storyboard feature of Xcode. My app consists of a tabbar which displays one of three viewcontrollers. Two out of three are simple viewcontrollers (single screens) and one is a splitviewcontroller. The splitview is tricky; using the stock xcode components I've drawn a master / table and a detail view. The table works as expected, but now I want to use mt.d to fill the detailview (later I need it to depend on the selection of the master, but not for now). I've subclassed the splitviewcontroller; in the viewdidload event I've created a mt.d dialogviewcontroller. Now I'm trying to push the dialogviewcontroller to the detailview, using the splitviewcontroller.viewcontrollers array. Doesn't seem to work; when running the app it still some an empty screen for the detail view (as drawn in xcode). Any clues for doing what I want? Thanx!

  • Best way to "un-promote" files in Accurev?

    - by Luke Rinard
    My company uses Accurev for source control, and for all its benefits, there's one simple action that I just can't figure out how to accomplish. Often we have someone accidentally push a file up too far in our stream structure -- from the "Development" stream to the "Release" stream, for example. What is the best way to "un-promote" this file? That is to say, to get the old version of the file back into the "Release" stream, and keep the new version of the file in the "Development" stream, where it belongs? Just doing a "Revert to Backed" or other Revert action on the file in the Release stream will either cause an old version of the file to propagate down into Development, or will make the file disappear entirely. In the above case, the developer will have to jump through hoops with setting basis times on streams, or use the command line tool to do a checkout of an old transaction, to get the file back. Sometimes the people in question are non-technical, so this is not a good solution. I have also considered moving the files to a "higher ground" stream, reverting, and then cross-promoting them to the lower stream again. This seems really kludgy. It seems like Accurev is obscure enough that Google is no help, so I turn to the good folks of StackOverflow for help -- has anybody figured out the "Accurevy" way to accomplish this?

  • Dojo DnD: how to access newly copied node on onDndDrop event?

    - by toshinao
    Hi. I am working on code like the following. 01: var c1 = new dojo.dnd.Source('container1', {copyOnly:true}); // container1 is a div 02: var c2 = new dojo.dnd.Source('container2'); // container2 is a div 03: var list = []; 04: for (var i = 0; i < 3; i++) { list.push( dojo.create('div') ); } 05: c1.insertNodes(false, list); 06: 07: function checkDndCopy(nodes, target){ 08: dojo.forEach(nodes, function(node){ alert(node.id); } ); 09: } 10: dojo.subscribe("/dnd/drop", function(){ 11: var mgr = dojo.dnd.manager(); 12: checkDndCopy(mgr.nodes, mgr.target); 13: }); The nodes inserted to the c1 at line 05 have id of "dojoUnique1, donoUnique2, dojoUnique3". On a event of drag and drop a node from c1 to c2, a onDndDrop event is fired and the subscribe method defined in line10-13 is invoked. I expected that newly copied node appears in the nodes (for example) at line 08. But this is not true. When dojoUnique1 is target of drag and drop, nodes at line 08 contains only dojoUnique1. I want to modify some attributes of newly copied nodes on the event of onDndDrop. Please let me know how such a thing is realized.

  • How do I access data from local XML files in a webOS application on the Palm Pre?

    - by Brijesh Patel
    I am new at Mojo framework and Palm webOS. I want to just retrieve data from XML files using xmlhttprequest (Ajax). I am trying to get data from following script. this.items = []; var that = this; var request = new Ajax.Request("first/movies.xml", { method: 'get', evalJSON: 'false', onSuccess:function(transport){ var movieTags = transport.responseXML.getElementsByTagName('movie'); for( var i = 0; i < movieTags.length; i++ ){ var title = movieTags[i].getAttribute('title'); that.items.push({text: title}); } }, onFailure: function(){ alert('Something went wrong...') } }); My XML files are in the first/movies.xml folder. From that I am trying to access and retrieve data. but not display anything in the screen of Palm Pre emulator. So can anyone is having idea about this issue? Please give a link where can I find the source code for getting data from XML files in webOS.

  • How does one properly redefine self while avoiding the "Multiple methods named ..." warning?

    - by Elise van Looij
    In Apple's The Objective-C Programming Language: Defining a Class the section named "Redifining self" recommends that that class methods allocate and return instances use 'self' only to allocate an instance and then refer only to that instance. Thus, I have a number of subclasses, that have class methods along the lines of: + (id)scrollViewWithFrame: (NSRect)rectFrame { id newInstance = [[[self alloc] initWithFrame:rectFrame] autorelease]; [newInstance setHasHorizontalScroller: YES]; [newInstance setHasVerticalScroller: YES]; [newInstance setBorderType: NSNoBorder]; [newInstance setAutoresizingMask: (NSViewWidthSizable | NSViewHeightSizable)]; return newInstance; } The above is, of course, a subclass of NSScrollView. Unfortunately, Xcode 3.x all these NSView subclasses now raise warnings: "Warning: Multiple methods named '-setAutoresizingMask' found". I believe it has something to do with GCC 4.2, the settings of which I have not changed. The warning is correct, of course, since NSView and its various subclasses all implement setAutoresizingMask, but it is also unnecessary. Since they're only warnings, I ignore them but there is a risk that in between the thirty or so unnecessary ones, a really useful warning lurks which I simply don't see. So, what to do? I do want to adhere to good coding practices and I want to build warning-free apps -- how can I do both?

  • Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"

    - by jtrim
    I'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree: http://gitorious.org/x264-arm that seems to have support for the ARM platform. Here is my config line: ./configure --cross-prefix=/usr/bin/ --host=arm-apple-darwin10 --extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/" ...and inside configure I'm using the gas-preprocessor script (first link above) as my assembler: gas-preprocessor.pl gcc When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols: ld: warning: option -s is obsolete and being ignored ld: warning: -force_cpusubtype_ALL will become unsupported for ARM architectures ld: warning: in /usr/lib/crt1.o, missing required architecture arm in file ld: warning: in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file ld: warning: in /usr/lib/libm.dylib, missing required architecture arm in file ld: warning: in /usr/lib/libpthread.dylib, missing required architecture arm in file ld: warning: in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file ld: warning: in /usr/lib/libSystem.dylib, missing required architecture arm in file Undefined symbols: My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas?

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • Delete NSManageObject at the event tableView:commitEditingStyle:forRowAtIndexPath:

    - by David.Chu.ca
    I got exception when I tried to delete one NSManageObject at the event of tableView:commitEditingStyle:forRowAtIndexPath:. Here is the part of my codes: - (void)tableView:(..)tableView commitEditingStyle:(..)editingStyle forRowAtIndexPath:(..)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [managedObjectContext deleteObject: [fetchedResultController objectAtIndexPath:indexPath]]; ... } } The exception was thrown at the line of deleteObject:(method of my local NSManagedObjectContext). This is the exception message: uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x3d07a30 <x-coredata://0D2CC9CB-042B-496D-B3FE-5F1ED64EAB97/paymentType/p2> has been invalidated.' I tried to get entity object first and then to delete it. The entity looks OK but still the exception was at delete: NSManagedObject *entityToDelete = [fetchedResultsController objectAtIndexPath:indexPath]; [mangedObjectContext deleteObject:entityToDelete]; // Exception again. I am not sure if the entity object retrieved from the fetchedResultsController(NSFetchedResultsController type) cannot be deleted? If so, is there any other way to get the entity object for deleting? I found that in the Apple's Core Data Tutorial for iPhone with events example, there is on NSArray to hold event entity objects. I am not sure if that's necessory to use NSArray to hold my local entity objects and then use it for deleting?

  • JQUERY, AutoSuggest that doesn't kill the Server on ever keyup

    - by nobosh
    I'm working to build a JQUERY enabled AutoSuggest plugin, inspired by Apple's spotlight. Here is the general code: $(document).ready(function() { $('#q').bind('keyup', function() { if( $(this).val().length == 0) { // Hide the q-suggestions box $('#q-suggestions').fadeOut(); } else { // Show the AJAX Spinner $("#q").css("background-image","url(/images/ajax-loader.gif)"); $.ajax({ url: '/search/spotlight/', data: {"q": $(this).val()}, success: function(data) { $('#q-suggestions').fadeIn(); // Show the q-suggestions box $('#q-suggestions').html(data); // Fill the q-suggestions box // Hide the AJAX Spinner $("#q").css("background-image","url(/images/icon-search.gif)"); } }); } }); The issue I want to solve well & elegantly, is not killing the sever. Right now the code above hits the server every time you type a key and does not wait for you to essentially finish typing. What's the best way to solve this? A. Kill previous AJAX request? B. Some type of AJAX caching? C. Adding some type of delay to only submit .AJAX() when the person has stopped typing for 300ms or so? Thanks

  • How can I filter a JTable?

    - by Jonas
    I would like to filter a JTable, but I don't understand how I can do it. I have read How to Use Tables - Sorting and Filtering and I have tried with the code below, but with that filter, no rows at all is shown in my table. And I don't understand what column it is filtered on. private void myFilter() { RowFilter<MyModel, Object> rf = null; try { rf = RowFilter.regexFilter(filterFld.getText(), 0); } catch (java.util.regex.PatternSyntaxException e) { return; } sorter.setRowFilter(rf); } MyModel has three columns, the first two are strings and the last column is of type Integer. How can I apply the filter above, consider the text in filterFld.getText() and only filter the rows where the text is matched on the second column? I would like to show all rows that starts with the text specified by filterFld.getText(). I.e. if the text is APP then the JTable should contain the rows where the second column starts with APPLE, APPLICATION but not the rows where the second column is CAR, ORANGE. I have also tried with this filter: RowFilter<MyModel, Integer> itemFilter = new RowFilter<MyModel, Integer>(){ public boolean include(Entry<? extends MyModel, ? extends Integer> entry){ MyModel model = entry.getModel(); MyItem item = model.getRecord(entry.getIdentifier()); if (item.getSecondColumn().startsWith("APP")) { return true; } else { return false; } } }; How can I write a filter that is filtering the JTable on the second column, specified by my textfield?

  • Image animation over CGContextDrawPDFPage

    - by BittenApple
    I'm modifying the QuartzDemo sample app from Apple. In QuartzViewController.m I have modifications (by DyingCactus) which replac the back button and add a method to handle the back button press as follows: -(void)viewDidLoad { // Add the QuartzView [scrollView addSubview:self.quartzView]; //add custom back button if this is the PDF view... if ([self.quartzView isKindOfClass:[QuartzPDFView class]]) { self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"QuartzDemo" style:UIBarButtonItemStyleBordered target:self action:@selector(myBackButtonHandler:)]; } } - (void)myBackButtonHandler:(id)sender { [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations]; } - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [self.navigationController popViewControllerAnimated:YES]; } I have a PNG image in resources folder called "bookmark.png" and would like to have that image animate as in animation in the example above. The image can be loaded in an UImageview or something and lets say that I have one called bookmark. How do I call that instead of self.quartzview in this part of code: [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations];

  • How does overlayViewTouched notification work in the MoviePlayer sample code

    - by Jonathan
    Hi, I have a question regarding the MoviePlayer sample code provided by apple. I don't understand how the overlayViewTouch notification works. The NSlog message I added to it does not get sent when I touch the view (not button). // post the "overlayViewTouch" notification and will send // the overlayViewTouches: message - (void)overlayViewTouches:(NSNotification *)notification { NSLog(@"overlay view touched"); // Handle touches to the overlay view (MyOverlayView) here... } I can, however, get the NSlog notification if I place it in -(void)touchesBegan in "MyOverlayView.m". Which makes me think it is recognizing touches but not sending a notification. // Handle any touches to the overlay view - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; if (touch.phase == UITouchPhaseBegan) { NSLog(@"overlay touched(from touchesBegan") // IMPORTANT: // Touches to the overlay view are being handled using // two different techniques as described here: // // 1. Touches to the overlay view (not in the button) // // On touches to the view we will post a notification // "overlayViewTouch". MyMovieViewController is registered // as an observer for this notification, and the // overlayViewTouches: method in MyMovieViewController // will be called. // // 2. Touches to the button // // Touches to the button in this same view will // trigger the MyMovieViewController overlayViewButtonPress: // action method instead. NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc postNotificationName:OverlayViewTouchNotification object:nil]; } } Can anyone shed light on what I am missing or doing wrong? Thank you.

  • passing hashes to a subroutine

    - by Vishalrix
    In one of my main( or primary) routines,I have two or more hashes. I want the subroutine foo() to recieve these possibly-multiple hashes as distinct hashes. Right now I have no preference if they go by value, or as references. I am struggling with this for the last many hours and would appreciate help, so that I dont have to leave perl for php! ( I am using mod_perl, or will be) Right now I have got some answer to my requirement, shown here From http://forums.gentoo.org/viewtopic-t-803720-start-0.html # sub: dump the hash values with the keys '1' and '3' sub dumpvals { foreach $h (@_) { print "1: $h->{1} 3: $h->{3}\n"; } } # initialize an array of anonymous hash references @arr = ({1,2,3,4}, {1,7,3,8}); # create a new hash and add the reference to the array $t{1} = 5; $t{3} = 6; push @arr, \%t; # call the sub dumpvals(@arr); I only want to extend it so that in dumpvals I could do something like this: foreach my %k ( keys @_[0]) { # use $k and @_[0], and others } The syntax is wrong, but I suppose you can tell that I am trying to get the keys of the first hash ( hash1 or h1), and iterate over them. How to do it in the latter code snippet above?

  • Snow Leopard & LSUIElement -> application not activating properly, window not "active" despite being

    - by Frank R.
    Hi, I'm running into a few problem with a background application that uses LSUIElement=1 to hide its dock item, menu bar and prevent it from appearing in the Command-Tab application switcher. It seems to be a Snow Leopard only problem. The application places an NSStatusItem in the menu bar and pops up a menu when clicked on. Selecting "Preferences..." should bring up an NSWindow with the preferences. The first thing that doesn't seem to work is that the Window does not get ordered in at the front, but appears behind all other application windows. I tried to fix this by calling [[NSApplication sharedApplication] activateIgnoringOtherApps: YES] but that didn't work. After a while I figured out that the menu is blocking the message to the run loop from being sent, so I wrote another method on the MainController and sent the message with a delay: [self performSelector:@selector(setFront:) withObject: [preferencesController window] afterDelay:1.0]; -(void)setFront: (id) theWindow { [[NSApplication sharedApplication]activateIgnoringOtherApps:YES]; [theWindow orderFrontRegardless]; [theWindow makeKeyWindow]; [[NSApplication sharedApplication] activateIgnoringOtherApps:YES]; } Note the send-every-possible-message-to-make-it-do-what-it-should-be-doing-approach. This works, kind-of, the window is brought to the front on top of all other windows from all apps, BUT most of the time it isn't active, meaning it's title bar is greyed out. Clicking on the title bar won't make the window active either. Clicking INSIDE of the window will make it active!? This all didn't seem to be a problem in Leopard; just calling activateIgnoringOtherApps and making the window key seemed to work just fine. In Snow Leopard there is a new API designed to replace LSUIElement that is supposed to emulate its behaviour: http://developer.apple.com/mac/library/releasenotes/cocoa/appkit.html I've played around with that, but it's SL-only and I haven't been able to get LSUIElement being set. Any help would be greatly appreciated!

  • PHP: Array of objects is empty when I come to retrieve one from the array

    - by Tom
    Good morning, I am trying to load rows from a database and then create objects from them and add these objects to a private array. Here are my classes: <?php include("databaseconnect.php"); class stationItem { private $code = ''; private $description = ''; public function setCode($code ){ $this->code = $code; } public function getCode(){ return $this->code; } public function setDescription($description){ $this->description = $description; } public function getDescription(){ return $this->description; } } class stationList { private $stationListing; function __construct() { connect(); $stationListing = array(); $result = mysql_query('SELECT * FROM stations'); while ($row = mysql_fetch_assoc($result)) { $station = new stationItem(); $station->setCode($row['code']); $station->setDescription($row['description']); array_push($stationListing, $station); } mysql_free_result($result); } public function getStation($index){ return $stationListing[$index]; } } ?> As you can see I am creating a stationItem object per database row (which for now has a code and description) and I then push these on to the end of my array which is held as a private variable in stationList. This is code which creates this classes and attempts to access the properties on them: $stations = new stationList(); $station = $stations->getStation(0); echo $station->getCode(); I am finding that the sizeof($stationList) at the end of the constructor is 1 but then it is zero when we come to try to get an object from the array using the index. Therefore the error that I get is: Fatal error: Call to a member function getCode() on a non-object Please can someone explain to me why this is happening? I guess I am misunderstanding how object references work in PHP5.

  • Starting one BlackBerry screen from another.

    - by DanG
    I've recently run into a snag while putting on the finishing touches for my BlackBerry app. I'm building a login screen which, if the user is successful in logging in, goes to a data loading screen, and then to a home screen. From the home screen, you can use the app. Everything works great but one thing, I can't seamlessly move from the login screen to the loading screen, to the home screen. I can move from the login screen to the loading screen ok, because I'm doing that via a button click which is on the GUI thread, but then I have the login screen at the bottom of the stack and can't get it out using the dismiss method. Once in the loading screen, I can't push the home screen because I'm not doing it via the gui method, though I'm able to update the GUI via the following piece of code: private void checkData(){ Timer loadingTimer = new Timer(); TimerTask loadingTask = new TimerTask() { public void run() { // set the progress bar progressGaugeField.setValue(DataManager.getDataLoaded()); // for repainting the screen invalidate(); } }; loadingTimer.scheduleAtFixedRate(loadingTask, 500, 500); } Does anyone know how to solve my problem of moving seamlessly from the login screen to the loading screen to the home screen? Note: once I'm at the home screen I'd like to have it be the only screen on the stack. Thanks!

  • Google GWT cross-browser support: is it BS ?

    - by Tim
    I developed a browser-deployed full-text search app in FlashBuilder which communicates RESTfully with a remote web-server. The software fits into a tiny niche--it is for use with ancient languages not modern ones, and there's no way I'm going to make any money on it but I did spend a lot of time on it. Now that Apple won't allow Flash on the iPad, I'm looking for a 100% javascript solution and was led to consider GWT. It looked promising, but one of the apps being "showcased" as a stellar example of what can be done with GWT has this disclaimer on their website (names {removed} to protect the potentially innocent) : Your current web browser (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5) is not officially supported by {company and product name were here}. If you experience any problems using this site please install either Microsoft Internet Explorer 6+ or Mozilla Firefox 3.5+ before contacting {product name was here} Support. What gives when GWT apps aren't "officially" supported on Chrome? What grade (A, B, C, D, F) would you give to GWT for cross-browser support? For folks who don't get these kinds of letter grades, A is "excellent" and "F" is failure, and "C" is average. Thanks for your opinions.

  • iPhone OpenGL Splash Screen? How?

    - by Kyle
    My app is based pretty much on the EAGLView in the SDK. It doesn't incorporate a ViewController. Rather it simply inits GL and starts painting immediately.. Currently, my app will load a very small PNG and displays it as quickly as possible. On a 3GS this is rather instant, but on a 3G it can take about 2 seconds. In the latter case of the 3G, the user is looking at a black screen for that time. Is this behavior allowed by Apple? Is there any way to alter this SDK example so that it makes use of 'default.png'? It doesn't seem so straight forward to me. I want my user to see an image as quickly as possible, and I also don't want to be rejected for such a little quirk like this as well. In the guidelines, they encourage you to use default.png for standard applications to show a sort of mockup of the interface while it actually loads. I want to initialize OpenGL, and ALSO display this. This default.png is loaded before the app screen launches. This is EXACLTY what I want to make use of. Any help is appreciated. Thanks!

When I do ls -l /mnt here is what I see ls -l /mnt ls -l /mnt drwxr-xr-x root system 2010-12-24 03:41 asec drwx------ root root 2010-12-24 03:41 secure d--------- system system 2010-12-24 03:41 sdcard whereas if I go to the directory where I created emu_sdcard - I see a lock has been issued, as shown here C:dir android-dev\emu_sdcard Volume in drive C is Preload Volume Serial Number is A4F3-6C29 Directory of C:\android-dev\emu_sdcard 12/24/2010 03:41 AM . 12/24/2010 03:41 AM .. 12/24/2010 03:17 AM 8,388,608 emu_logFile 12/24/2010 03:41 AM emu_logFile.lock 1 File(s) 8,388,608 bytes 3 Dir(s) 50,347,704,320 bytes free I have looked at these and other SO questions Android Emulator sdcard push error: Read-only file system (2) Not able to view SDCard folder in the FileExplorer of Android Eclipse I have added the following to AndroidManifest.xml **uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" ** Please let me know your thoughts - what am I missing here? Why does canWrite return false? What should I do to add permissions to sdcard?

  • Debugging NSoperation BAD ACCESS within graphics context

    - by Joe
    I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

  • Architecting iPhone Views - seeking help on a specific issue + general advice

    - by Ev
    Hi there, I am a web developer (rails, python) that is new to iPhone development. I've done some desktop development in the past within the MS environment (C#). I'm trying to build a really simple iPhone application and I am confused by the way that views work in general. If someone can provide advice for my particular problem, along with some resources where I can learn how to architect iPhone views in the future, that would be awesome. I feel like a lot of the Apple documentation that I've come across is too specific - I am lacking a fundamental understanding of how views work on the iPhone. My particular problem looks like this: I need one view that displays some downloaded text content. This is the view that shows when the app loads, and it is pretty straightforward. Then I need a settings area (I've already decided I don't want to use the iPhone settings area). The settings area main page will have some text fields on it. It will also have a 2-row grouped table. Each cell in that table will take you to another view which also has a grouped table used for multi-select. I suspect that I can reuse the same view for these two final "detailed setting" views. In summary: home page settings main page detailed setting 1 detailed setting 2 Any help and advice appreciated.

  • Getting SSL to work with Apache/Passenger on OSX

    - by jonnii
    I use apache/passenger on my development machine, but need to add SSL support (something which isn't exposed through the control panel). I've done this before in production, but for some reason I can't seem to get it work on OSX. The steps I've followed so far are from a default apache osx install: Install passenger and passenger preference pane. Add my rails app (this works) Create my ca.key, server.crt and server.key as detailed on the apple website. At this point I need to start editing the apache configs, so I added: # Apache knows to listen on port 443 for ssl requests. Listen 443 Listen 80 I thought I'd try editing the passenger pref pane generated config first to get everything working, when I add: It starts off looking like this <VirtualHost *:80> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <Directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </Directory> </VirtualHost> I then append this: <VirtualHost *:443> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </directory> # SSL Configuration SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars +StrictRequire #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl.key/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl.key/server.key SSLCertificateChainFile /private/etc/apache2/ssl.key/ca.crt SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 </VirtualHost> The files referenced all exist (I doubled checked that), but now when I restart my apache I can't even get to myapp.local. However apache can still server the default page when I click on it in the sharing preference panel. Any help would be greatly appreciated.

  • Audio in xCode4.x is producing console warnings

    - by David DelMonte
    While the app works, I am seeing pages of console log warnings when I'm running my app on the simulator. Even Apple's "LoadPresetDemo" sample app produces the same warning messages. I don't want to reproduce them all here (about 500 lines), but here are few. I would appreciate any insight into what's going on...
