• how to get IndexPath

  - by user145883

  in iphone application. I'm trying to get indexPath.row value to do something on the basis of row selected in programmatically created tableview. Can someone please tell me why is the indexPath.row value is not coming correct. It's some thing like 21487...3? NSUInteger nSections = [myTableView numberOfSections]; NSUInteger nRows = [myTableView numberOfRowsInSection:nSections]; NSIndexPath *indexPath = [NSIndexPath indexPathForRow: nRows inSection:nSections]; NSLog(@"No of sections in my table view %d",nSections); NSLog(@"No of rows in my table view %d",nRows); NSLog(@"Value of selected indexPath Row %d", indexPath.row); Thanks, Aaryan

• How do I create a sqlite 3 (.sl3) database file?

  - by BC

  I have a *.sqlite file... but I need the database in *.sl3 format? What software/tool can I us to create that? What are the steps? This is to be used in an iPhone app. Original developer used an .sl3 file, now that I have updated the DB - I can't seem to export/generate a .sl3 file I have tried just changing the extension - all the way to inserting the *.sqlite file in XCode and pointing the app delegates to the new DB file format... doesn't work. Thanks in advance...

• Program crash on deque from queue

  - by SwedishGit

  My first question asked here, so please excuse if I fail to include something... I'm working on a homework project, which basically consists of creating a "Jukebox" (importing/exporting albums from txt files, creating and "playing" a playlist, etc.). I've become stuck on one point: When "playing" the playlist, which consists of a self-made Queue, a copy of it is made from which songs are dequeued and printed out with a time delay. This appears to run fine on the first run through the program, but if the "play" option is chosen again (with the same playlist, created from a different menu option), it crashes before managing to print the first song. It also crashes if creating a new playlist, but then it manages to print some songs (seem to depend on the number of songs in the first/new playlists...) before crashing. With printouts I've been able to track the crashing down to being on the "item = n-data" call in the deque function... but can't get my head around why this would crash. Below is the code I think should be relevant... let me know if there are other parts that would help if I include. Edit: The Debug Error shown on crash is: R6010 abort() has been called The method to play from the playlist: void Jukebox::playList() { if(songList.getNodes() > 0) { Queue tmpList(songList); Song tmpSong; while(tmpList.deque(tmpSong)) { clock_t temp; temp = clock () + 2 * CLOCKS_PER_SEC ; while (clock() < temp) {} } } else cout << "There are no songs in the playlist!" << endl; } Queue: // Queue.h - Projekt-uppgift // Håkan Sjölin 2014-05-31 //----------------------------------------------------------------------------- #ifndef queue_h #define queue_h #include "Song.h" using namespace std;

• Own an iPad, iPhone, or Touch? Add GWB to your Home

  - by Staff of Geeks

  I know it is goofy to geek out about such things, but I am a pretty goofy geek.  Today we published support for the Apple icons for devices like the iPhone, iPad, or iPod Touch.  Now when you add Geekswithblogs.net to your home screen (via the little + in Safari) it will load the icon to the left instead of a screenshot of the site.  We have been using my iPhone and iPad to surf to GWB for awhile and we were tired of that screenshot.  Simple Google/Bing search and a little Photoshop CS5 (Amazing!!!) work and there it is.  Next step we are taking in the Apple iPad/Phone arena is getting our developer kit and seeing what possiblities there are for Geekswithblogs.net and a custom App.  Got any ideas? Here is a shot of my iPad 3G: Also, would anyone be interested in a Geekswithblogs.net custom background for the iPhone or iPad?  I can put something together real quick if there are any takers.

• What can I do to make sure my code gets maintained in a developer light environment?

  - by asjohnson

  I am a contract data analyst, so I bounce between jobs every 3-6 months, which I find to be a good fit for me, but it leads to some problems when it comes to coding. I mostly do statistics (I've asked a similar question on cross validated, but the answers there are not relevant here), but I have also found out that the business world loves excel and loves copying and pasting the same thing over and over again even more. This led me to learn how to write VBA scripts and then VB.NET programs to automate as many of these reports as I can. I am certain my programs are not the most elegant, but I put a good bit of effort into making sure they work under as many cases as I can test, I add in exceptions and try to code so the program can handle changes in the files that it processes, but there is a limit, if you remove a huge portion of the data, there is a good chance my program is going to trip up, which I accept will inevitably happen. Usually a pretty minor change in the code fixes the problem and I do try and comment my code and make it readable under the assumption that some other person will have to read it some day. My problem is that I generally get put on teams of folks with essentially no experience with programming (like VBA would be a huge stretch for anyone I work directly with). I am wondering what I should be doing as the person that wrote the code to do my best to keep it maintained. I have two approaches in mind (outlined next), but would be very happy to get any advice. Solution 1: Find the more tech savvy coworkers and run them through the programs and what basic changes can be made. Honestly automating excel is about as easy as it can get when it comes to programming, so I feel like I could teach someone the basics of maintaining it pretty quick. Solution 2: Get in touch with the IT department and show them what is going on and maybe they will be able to help. The problem here is that the IT department is constantly swamped (as I'm sure many of you know) and I feel like kind of a jerk for dumping more things on them. I do leave my personal email address with places and am willing to answer quick questions via email, but I view the need for more exhaustive maintenance as something of an inevitability and would like to make sure I do my due diligence to make sure it gets done. I imagine some combination of the two approaches outlined there, but is there any kind of heads up I should give IT? I feel like I would be annoyed if I started getting requests to fix a program that I had never seen from some random guy that is no longer there.

  Brevets : Samsung compte poursuivre Apple sur l'utilisation de la 4G LTE dans l'iPhone 5 le constructeur dénigre Android aux Pays-Bas Apple se prépare pour le lancement demain de l'iPhone 5. De son côté, Samsung se prépare également. Mais pour bloquer la commercialisation du nouveau dispositif d'Apple. Selon un article du Korea Times, le constructeur coréen a confirmé qu'il allait trainer Apple devant les tribunaux, suite à la demande de la firme à la pomme d'interdire la gamme Galaxy S sur le territoire américain. Pour rappel, Samsung avait été condamné à verser un milliard de dollars à Apple pour avoir violé les brevets de la société sur le Design de l'iPhone. La ...

  Les utilisateurs d'iPhone se regroupent en sept types, et vous, à quelle catégorie appartenez-vous ? Actuellement, près de 70 millions de personnes dans le monde utilisent un iPhone.

• L'iPhone 4.0 sera multi-tâches, approuvez-vous cette décision ?

  L'iPhone 4.0 sera multi-tâches, approuvez-vous cette décision ? Le reproche le plus couramment fait à l'iPhone est son incapacité de gérer le multi-tâche. Plus exactement, l'appareil en est capable, mais Apple empêche l'exécution de cette fonctionnalité. En effet, il n'est actuellement pas possible d'utiliser plusieurs applications simultanément, sauf iPod, mail, sms et Safari. Ceci, afin de préserver les batteries de ses appareils et de faire de l'iPhone un mobile très simple à utiliser (certains néophytes ont du mal à s'y retrouver lorsque plusieurs programmes fonctionnent en parallèle). Le hic, c'est que tous les concurrents de la pomme proposent des smartphones multi-tâches. Récemment, Motorola a diffusé des publ...

• Problem using easy_install on Windows 7, 64 bit. (cannot find python.exe)

  - by Rune

  Hi, I have just now installed Python 2.6 on my Windows 7 (64 bit) Lenovo t61p laptop. I have downloaded Sphinx and nose and apparently installed them correctly using python setup.py install (at least no errors were reported during the installation). Now I am trying to install pymongo using easy_install but I am not having much success. It seems that easy_install isn't working at all. I execute easy_install as administrator: C:\>easy_install Cannot find Python executable C:\Program Files\Python26\python.exe The path C:\Program Files\Python26\python.exe is correct. I have found this bug report on bugs.python.org which seems to be related, although its status is 'Resolved'. Do you have any ideas as to what may be wrong? Any pointers, hints or tips for diagnosing the problem further would be greatly appreciated.

• OpenCV and iPhone

  - by gn-mithun

  Hello, I am writing an application to create a movie file from a bunch of images on an iPhone. I am using OpenCv. I downloaded openCv static libraries for arm(iPhones native instruction architecture) and the libraries were generated just fine. There were no problems linking to them libraries. As a first step, i was trying to create a .avi file using one image, to see if it works. But cvCreateVideoWriter always returns me a NULL value. I did some searchin and i believe its due to the codec not being present. I am trying this on the iPhone simulator. this is what i do... (void)viewDidLoad { [super viewDidLoad]; UIImage *anImage = [UIImage imageNamed:@"1.jpg"]; IplImage *img_color = [self CreateIplImageFromUIImage:anImage]; //The image gets created just fine CvVideoWriter *writer = cvCreateVideoWriter("out.avi",CV_FOURCC('P','I','M','1'), 25,cvSize(320,480),1); //writer is always null int result = cvWriteFrame(writer, img_color); NSLog(@"\n%d",result); //hence this is also 0 all the time cvReleaseVideoWriter(&writer); } I am not sure about the the second parameter. What sort of codec or what exactly it does... I am a n00B in this. Any suggestions?

• When my UIViewController accesses an NSArray in my AppDelegate from an IBAction it crashes the progr

  - by JasonClark

  I have a couple UIViewControllers that I am trying to access an array inside my AppDelegate. When I use an IBAction UIButton and in that method I access my AppDelegate my program dies silently. Nothing in output or the debugger, it just stops. If I run it several times I can see that it is failing to access the array properly. To investigate this problem I created a very basic app. In my AppDelegate.h I declared and set properties for the array #import <UIKit/UIKit.h> @class MyViewController; @interface MyAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MyViewController *viewController; NSArray *images; } @property (nonatomic, retain) NSArray *images; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyViewController *viewController;` In the AppDelegate.m I synthesised and initialized the NSArray (Also made sure the images were added to the Resources folder). @synthesize images; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { images = [NSArray arrayWithObjects: [[NSBundle mainBundle] pathForResource:@"bamboo_nw" ofType:@"jpg"], ..... nil]; NSLog(@"init images size:%i",[images count]); [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } In my UIViewController.h I added class, imported header file, declared, and set properties for my AppDelegate pointer. #import <UIKit/UIKit.h> #import "MyAppDelegate.h" @class MyAppDelegate; @interface MyViewController : UIViewController { MyAppDelegate *mainDelegate; IBOutlet UIButton mybutton; } @property (nonatomic, retain) MyAppDelegate mainDelegate; @property (nonatomic, retain) UIButton *mybutton; -(IBAction) doSomething;` In my UIViewController.m I synthesize and assign my AppDelegate. I set up an IBAction that will log the same count of the NSArray from the AppDelegate. #import "MyViewController.h" #import "MyAppDelegate.h" @implementation MyViewController @synthesize mybutton; - (void)viewDidLoad { mainDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"vdl images size:%i",[mainDelegate.images count]); [super viewDidLoad]; } -(IBAction) doSomething { NSLog(@"ds images size:%i",[mainDelegate.images count]); } I print the size of the NSArray in the AppDelegate when I create it, in the ViewController when I first assign my AppDelegate pointer, and then as a result of my IBAction. I find that everytime I hit the button the program dies. On the third time I hit the button, I saw that it ran my IBAction but printed my array size as 1 instead of 8. Am I missing something? Also, why don't I get stack traces or anything, the debugger just dies silently? Thanks in advance for any help!

• How to debug KVO

  - by user8472

  In my program I use KVO manually to observe changes to values of object properties. I receive an EXC_BAD_ACCESS signal at the following line of code inside a custom setter: [self willChangeValueForKey:@"mykey"]; The weird thing is that this happens when a factory method calls the custom setter and there should not be any observers around. I do not know how to debug this situation. Update: The way to list all registered observers is observationInfo. It turned out that there was indeed an object listed that points to an invalid address. However, I have no idea at all how it got there. Update 2: Apparently, the same object and method callback can be registered several times for a given object - resulting in identical entries in the observed object's observationInfo. When removing the registration only one of these entries is removed. This behavior is a little counter-intuitive (and it certainly is a bug in my program to add multiple entries at all), but this does not explain how spurious observers can mysteriously show up in freshly allocated objects (unless there is some caching/reuse going on that I am unaware of). Modified question: How can I figure out WHERE and WHEN an object got registered as an observer? Update 3: Specific sample code. ContentObj is a class that has a dictionary as a property named mykey. It overrides: + (BOOL)automaticallyNotifiesObserversForKey:(NSString *)theKey { BOOL automatic = NO; if ([theKey isEqualToString:@"mykey"]) { automatic = NO; } else { automatic=[super automaticallyNotifiesObserversForKey:theKey]; } return automatic; } A couple of properties have getters and setters as follows: - (CGFloat)value { return [[[self mykey] objectForKey:@"value"] floatValue]; } - (void)setValue:(CGFloat)aValue { [self willChangeValueForKey:@"mykey"]; [[self mykey] setObject:[NSNumber numberWithFloat:aValue] forKey:@"value"]; [self didChangeValueForKey:@"mykey"]; } The container class has a property contents of class NSMutableArray which holds instances of class ContentObj. It has a couple of methods that manually handle registrations: + (BOOL)automaticallyNotifiesObserversForKey:(NSString *)theKey { BOOL automatic = NO; if ([theKey isEqualToString:@"contents"]) { automatic = NO; } else { automatic=[super automaticallyNotifiesObserversForKey:theKey]; } return automatic; } - (void)observeContent:(ContentObj *)cObj { [cObj addObserver:self forKeyPath:@"mykey" options:0 context:NULL]; } - (void)removeObserveContent:(ContentObj *)cObj { [cObj removeObserver:self forKeyPath:@"mykey"]; } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if (([keyPath isEqualToString:@"mykey"]) && ([object isKindOfClass:[ContentObj class]])) { [self willChangeValueForKey:@"contents"]; [self didChangeValueForKey:@"contents"]; } } There are several methods in the container class that modify contents. They look as follows: - (void)addContent:(ContentObj *)cObj { [self willChangeValueForKey:@"contents"]; [self observeDatum:cObj]; [[self contents] addObject:cObj]; [self didChangeValueForKey:@"contents"]; } And a couple of others that provide similar functionality to the array. They all work by adding/removing themselves as observers. Obviously, anything that results in multiple registrations is a bug and could sit somewhere hidden in these methods. My question targets strategies on how to debug this kind of situation. Alternatively, please feel free to provide an alternative strategy for implementing this kind of notification/observer pattern.

• Python in command line runs the wrong version?

  - by Deflect

  I have several versions of Python installed on a Windows 7 computer. I want to run Python 2.7 by default, but for whatever reason, typing python in the command line runs Python version 2.4.5. I've tried adding C:\Python27 to my system path variable as per this question, and manually combed my path variable it to make sure Python 2.4.5 wasn't tossed in there by mistake, but that didn't fix the issue. I have to type in C:\Python27\python.exe every time I want to access the correct version of python I want. What other places can I check? How can I make the command line use the correct version of python? I also found this but it's not for windows.

• Can I prevent a particular program from showing up in the taskbar on Windows XP?

  - by jsnlxndrlv

  I have a program that I need to run more or less continuously, but which I won't need to access very frequently. Currently, launching the program creates a window and causes the program to appear on the taskbar. I'm fine with the program window appearing, but I'd just as soon the taskbar be reserved for programs that I need to switch between frequently—it would be superior for this program to only appear as an icon in the notification area, if at all. Is this possible? How do I do this?

• Determine UIInterfaceOrientation on iPad

  - by JustinXXVII

  I don't need to specify the orientation in this case, I just need to detect it, but I'm having trouble. I have conditional code that should only work in portrait, and if the device is in landscape I need to do something else. Since the deviceOrientation is not necessarily the same as the interfaceOrientation, I can't come up with a way to test for portrait mode. Most tutorials I find on Google are ways to force landscape or do some sort of rotation. The only thing I want to do is just determine what the orientation is. Here is my code, which is not working: -(void)viewDidLoad { [super viewDidLoad]; //currentOrientation is declared as UIInterfaceOrientation currentOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation]; NSLog(@"%@",currentOrientation); // == NULL } I need to determine the value of the interfaceOrientation and program conditionally. Thanks for your help!

  Hi there! Im using a UIWebView to access a website, when i rotate the phone (landscape) the UIWebView is properly resized and the scrollbar are on the right place (on the right edge...) but when i acess any of input fields to fill the information required and exit it the UIWebView scrollbar jumps to the middle of screen (looks like it get back to 320, the width of the screen on portrait). Some useful info, this program was created using IB, have lots of outlets, im thinking about in do (redo) everything programmatically cause i was not the author of the first version...

• Interchanging presentModalViewController and pushViewController

  - by Neffster

  I am using a sample ViewController that is displayed in the sample program as a presentModalViewController. However, I want to use pushViewController on the UIViewController instead. The problem is that when I switch to pushViewController, the ViewController no displays properly. Functions in the ViewController are called, but I don't see anything. I change back to presentModalViewController and everything works. The question is what do I need to do to make pushViewController work? FCVC *fcVC; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"fcVC" owner:self options:nil]; fcVC = [array objectAtIndex:0]; A. [self presentModalViewController:fcVC animated:YES]; // "WORKS" or B. [self.navigationController pushViewController:fcVC animated:YES]; // "Doesn't work
