• iphone not displaying array variables correctly

  - by Rob

  I was reading a tutorial on how to do a UIPicker and found this code: - (IBAction)buttonPressed { NSInteger row = [userPicker selectedRowInComponent:0]; NSString *selected = [userPickerData objectAtIndex:row]; NSString *title = [[NSString alloc] initWithFormat:@"You selected %a", selected]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:@"Thank you for Choosing." delegate:nil cancelButtonTitle:@"You're Welcome" otherButtonTitles:nil]; [alert show]; [alert release]; [title release]; } - (void)viewDidLoad { // [super viewDidLoad]; NSArray *array = [[NSArray alloc] initWithObjects:@"New", @"Frank", @"Bob", @"Thor", nil]; self.userPickerData = array; [array release]; } The UIPicker displays correctly and the variables in the picker also display correctly. When the button is pressed then the alert message does come up but it says, "You selected.." and then it's a bunch of gibberish. Why aren't the array variables being passed correctly?

• Media Foundation: another way to call IMFActivate::ShutdownObject?

  - by KenC

  Hi, Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation. According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject. But there are two examples not following this rule: http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx and http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method. This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object? (Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject) Thanks in advance.

• What guides or standards do you use for CVS in your team ?

  - by PaulHurleyuk

  I'm starting to do a small amount of development within my company. I'm intending to use Git for CVS, and I'm interested to see what guidelines or standards people are using around CVS in their groups, similar to coding standards are often written within the group for the group. I'm assuming there will be things like; Commit often (at least every day/week/meeting etc) Release builds are always made from the master branch Prior to release, a new branch will be created for Testing and tagged as such. only bug fixes from this point onwards. The final release of this will be tagged as such and the bug fixes merged back into the trunk Each developer will have a public repo New features should get their own branch Obviously a lot of this will depend on what cvs you're using and how you've structured it.

• Releasing NSData causes exception...

  - by badmanj

  Hi, Can someone please explain why the following code causes my app to bomb? NSData *myImage = UIImagePNGRepresentation(imageView.image); : [myImage release]; If I comment out the 'release' line, the app runs... but a few times calling the function containing this code and I get a crash - I guess caused by a memory leak. Even if I comment EVERYTHING else in the function out and just leave those two lines, when the release executes, the app crashes. I'm sure this must be a newbie "you don't know how to clean up your mess properly" kind of thing ;-) Cheers, Jamie.

• In Lisp, Avoid "Cannot open load file" when using require

  - by Jesse

  I am working on a custom .emacs file that I will be able to use on several different computers. I would like to be able to load a mode if it exists on the system. If it does not exist I would like Emacs to stop showing the error: File error: Cannot open load file, X. For example: (require 'darkroom-mode) Results in: File error: Cannot open load file, darkroom-mode I am using file-exists-p to test if certain other files exist but for this test I would assume I need to search my load-path. I am new to Lisp so this is stumping me.

• Table View rotate, but not properly (shape change)

  - by Pencrace

  Hello everyone, Here is the thing. I have a ViewController which contain a view in full window. And the program run in landscape mode. I want to put an UITableView over the full screen view but only on right half part of the screen. So I add a UITableView in my view controller, I used the Interface Builder in order to set the Table View in the upper half of the screen so It will be on the right part in LandscapeLeft mode. I searched for on a lot of forum how to rotate my Table View. And so it does... except, It get stuck on the upper half of the landscape mode, it should stick on the right half. I'm not a iPhone coder since long, so I'm a bit confused on how to solve this problem. Do you have any idea on how to resize or make the TableView rotate properly. Thanks,

• How do you uninstall old custom installs of Xcode?

  - by Jonathan

  Hi, When I install a beta, I do a custom install into a separate folder to the latest release version. I have several old beta installs. How do I uninstall the old custom versions of xcode? Can I just trash the folder? Our do I need to use Terminal? The release notes suggest to use this: $ sudo /Library/uninstall-devtools --mode=all But will this just uninstall my original official release version 3.2? Thanks.

• Can't create admin user on Heroku

  - by Nick5a1

  I am new to rails and I have gone through Kevin Skoglund's Ruby on Rails 3 Essential Training course on Lynda.com. Through the course you set up a simple cms, which I did. It doesn't cover Git or deployment but I've pushed my simple cms to github (https://github.com/nick5a1/Simple_CMS) and deployed to Heroku (http://nkarrasch.herokuapp.com/). In order to deploy to Heroku I followed the Heroku setup guide (https://devcenter.heroku.com/articles/rails3) and switched my database from MySQL to PostgreSQL. As instructed I changed gen'mysql2' to gen 'sqlite3' in my Gemfile and ran bundle install before pushing. I then ran heroku run rake db:migrate. I'm running into 2 problems. When I try to log in (http://nkarrasch.herokuapp.com/access) I get an error "We're sorry, but something went wrong". I should instead be getting a flash message with invalid username/password combination. This is what I'm getting on my test environment on my local machine. Secondly, when I log into the Heroku console to create and create an admin user, when I try to save that user I get the following error: irb(main):004:0> user.save (1.2ms) BEGIN AdminUser Exists (1.9ms) SELECT 1 AS one FROM "admin_users" WHERE "admin_users"."username" = 'Nick5a1' LIMIT 1 (1.7ms) ROLLBACK => false Any advice on how to troubleshoot would be greatly appreciated :).

• PDO::ATTR_EMULATE_PREPARES => false

  - by user264058

  I'm new to php and PDO ,so i read this response to a similar post- Does PDO really not use prepared statements with mysql? Yes, by default (at least with version I tested) but native mode can be turned on manually. If not, can it be forced to do so By employing PDO::ATTR_EMULATE_PREPARES setting, the name is pretty self-explanatory. $dbh-setAttribute( PDO::ATTR_EMULATE_PREPARES, false ); should you do that? That's hardest question of them all. Well, I'd say - yes, you should. If you choose PDO as your db driver, there is no point in using it in the emulation mode. by YOUR COMMON SENSE Aren't prepared statements secure from SQL injection, why change if from 'true'-false?? what is native mode??

The problem has to be somewhere in here: - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath { NSMutableArray *array = [[fetchedResultsController fetchedObjects] mutableCopy]; id objectToMove = [[array objectAtIndex:sourceIndexPath.row] retain]; [array removeObjectAtIndex:sourceIndexPath.row]; [array insertObject:objectToMove atIndex:destinationIndexPath.row]; [objectToMove release]; for (int i=0; i<[array count]; i++) { [(NSManagedObject *)[array objectAtIndex:i] setValue:[NSNumber numberWithInt:i] forKey:@"userOrder"]; } [array release]; } Any guidance greatly appreciated!

• BlazeDS rejected connection from some IP address

  Hi, I'm using the BlazeDS binary version with Apache tomcat 6.0. And it seems there's a developer mode active and it only allows 3 IPs to connect to the application (Server). This is what the log says: [BlazeDS]MessageBroker '__default__' rejected connection from address 'xxx.xxx.xx.x'; Developer mode addresses already in use: xxx.x.xxx.xx, xxx.xxx.xxx.xxx, xx.xxx.xxx.xx (IP addresses are masked with 'x' for privacy) I have not added any special configuration to make developer mode active. I couldn't find any resources related to this scenario either. Please help. Thanks in Advance.

• Deploying Multiple Environments in Spring-MVC

  - by jboyd

  Currently all web apps are deployed using seperate config files: <!-- <import bean.... production/> --> <import bean... development/> This has disadvantages, even if you only need to swap out one config file, that I'm sure everyone is familiar with (wondering what just deployed without searching through XML is one of them) I want to add Logging to my application that basically says 'RUNNING IN PRODUCTION MODE', with a description of the services deployed and what mode they are working in. RUNNING IN PRODUCTION MODE Client Service - Production Messaging Service - Local and so on... Is this possible in Spring using a conventional deployment (putting a war on a server)? What other things do people do to manage deployments and software configurations? If not, what other ways could you achieve something similar?

• Conceptual question about NSAutoreleasePools

  - by ryyst

  In my Cocoa program, wouldn't a really simple way of dealing with autoreleased objects be to just create a timer object inside the app delegate that calls the following method e.g. every 10 seconds: if (pool) { // Release & drain the current pool to free the memory. [pool release]; } // Create a new pool. pool = [[NSAutoreleasePool alloc] init]; The only problems I can imagine are: 1) If the above code runs in a separate thread, an object might get autoreleased between the release call to the old pool and the creation of the new pool - that seems highly unlikely though. 2) It's obviously not that efficient, because the pool might get released if there's nothing in it. Likewise, in the 10 second gap, many many objects might be autoreleased, causing the pool to grow a lot. Still, the above solution seems pretty suitable to small and simple projects. Why doesn't anybody use it? What's the best practice of using NSAutoreleasePools?

• Implementing Multitasking on an iPhone/iOS4 Web App

  - by Peter Watts

  I am looking to build a web app that implements background audio and fast app switching. These features work out of the box, when run as regular Safari web pages, but as soon as you add the web-app-capable tag, and try to run in full screen mode, this functionality breaks. I did some testing and even the most basic web app will reload every time when you switch back to it. And seeing as it's a web app, we can't exactly implement the multitasking API. Has anyone found a work around? This isn't a deal-breaker, as you can just avoid full screen mode, but then you also lose the ability to use your own icon in the app switch tray. Perhaps this explains a lack of full screen mode in YouTube's new web app....

• Strange error: cannot convert from 'int' to 'ios_base::openmode'

  - by Dylan Klomparens

  I am using g++ to compile some code. I wrote the following snippet: bool WriteAccess = true; string Name = "my_file.txt"; ofstream File; ios_base::open_mode Mode = std::ios_base::in | std::ios_base::binary; if(WriteAccess) Mode |= std::ios_base::out | std::ios_base::trunc; File.open(Name.data(), Mode); And I receive these errors... any idea why? Error 1: invalid conversion from ‘int’ to ‘std::_Ios_Openmode’ Error 2: initializing argument 2 of ‘std::basic_filebuf<_CharT, _Traits* std::basic_filebuf<_CharT, _Traits::open(const char*, std::_Ios_Openmode) [with _CharT = char, _Traits = std::char_traits]’ As far as I could tell from a Google search, g++ is actually breaking the C++ standard here. Which I find quite astonishing, since they generally conform very strictly to the standard. Is this the case? Or am I doing something wrong. My reference for the standard: http://www.cplusplus.com/reference/iostream/ofstream/open/

• Programming for a 32-bit environment vs programming for a 64-bit environment / Build configurations

  - by Russel

  I was looking at some same code (a sample MS Visual Studio C++ project) recently with multiple build configurations (Release/Debug, Win32/x64). My question: What is the difference? I guess I understand Release/Debug (Release = finalized version of project, Debug = version used to run in debugger), but what things need to be considered when building different versions for Win32/x64 platforms? Is there any coding differences, or does this just affect how that same code is ultimately built into machine code? I know there are different library files depending on whether you're using a 32-bit or 64-bit system as well... Are all of these differences again just machine code? Would a 32-bit library file and its corresponding 64-bit library file be two files with exactly the same functions build from the same source code originally, and only differing in their machine code implementation? Thanks! --Russel

• Objective-C: when does an assigned object get deallocated

  - by Stefan Klumpp

  If I have a instance method and within this method I do something like this: NSString *peopleString = [peopleList componentsJoinedByString: @", "]; ... UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(16.0+6.0f, 4.0f, 252.0f, 12.0f)]; [likeLabel setText:peopleString]; [likeLabel setFont:[UIFont fontWithName:@"Arial" size:12]]; [likeRow addSubview:likeLabel]; [likeLabel release]; The componentsJoinedByString doesn't contain a new, copy or alloc, thus I don't have to release it. What I'm wondering though is, when my peopleString gets deallocated. Might it happen to early? Meaning, before I can set the text in my label. Should I better use a [[NSString alloc] initWithString:[peopleList componentsJoinedByString: @", "]]; and release it at the end of this method?
