• Version control for subtitle creation

  - by user3635

  We make subtitles for a TV series and I plan to use a VCS for it. The structure of project directory is like this: series/ episode1/nameofepisode1.str episode2/nameofepisode2.str episode3/nameofepisode3.str ... Question: When I finish subtitle of an episode, I want to assign release tag for this episode (episode1_v1). I wanted to use git for this, but in git tag is assigned only to the whole repository. What to do, so that I can view every episode progress separately? Maybe there are some more suitable VCS for this?

• How to log C++ exception if running outside debugger, otherwise rethrow

  - by Stefan Monov

  I wanna do something like this: int main() { try { runApp(); } catch(std::exception const& ex) { if(runningInDebugger()) throw; // let the IDE show me what went wrong else displayMsgBox("Something went wrong! " + ex.what()); } } Needs to work at least in VS2008 but the more debuggers it supports, the better. I want it to check for a debugger at runtime. I don't want to do "#ifdef NDEBUG", because I prefer not to do release builds at all (can't be bothered). So what should I use as a "runningInDebugger()" check?

• DLL response is too slow in Visual Studio [Resolved]

  - by magsto

  I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger? I found a setting that resolved my issue: Project Properties Debug Enable Debuggers select "Enable unmanaged code debugging". Now the DLL communication flowed smoothly. The DLL I use is a middleware between my app and a USB device. There is no Debug/Release version of the DLL.

• Working with the Objective-C/Cocoa flat namespace

  - by Stephen Blinkhorn

  I've not found anything that addresses my specific name space question as yet. I am working on some AudioUnit plug-ins featuring Cocoa based GUIs. The plug-ins use a common library of user interface classes (sliders, buttons etc) which are simply added to each Xcode project. When I recompile and distribute updates it is pretty much guaranteed that at least one user interface class will have been updated since the last release. If the user launches an older plug-in before an updated plug-in then the old Cocoa classes are already loaded into the run time and the plug-in attempts to use the older implementations - often resulting in a failure one way or another. I know frameworks are the intended solution but the overhead and backwards compatibility issues are not ideal. I prefix all class names where possible but what options do I have to ensure that each plug-in contains unique class names for the shared user interface classes?

• Core Data produces Analyzer warnings

  - by RickiG

  Hi I am doing the final touch ups on an app and I am getting rid of every compiler/analyzer warning. I have a bunch of Class methods that wrap my apps access to Core Data entities. This is "provoking" the analyzer. + (CDProductEntity*) newProductEntity { return (CDProductEntity*)[NSEntityDescription insertNewObjectForEntityForName:@"CDProductEntity" inManagedObjectContext:[self context]]; } Which results in an Analyzer warning: Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected In the method that calls the above Class Method I have this: CDProductEntity *newEntity = [self newProductEntity]; Which results in an Analyzer warning: Method returns an Objective-C object with a +1 retain count (owning reference) Explicitly releasing or autoreleasing a Core Data entity is usually very very bad, but is that what it is asking me to do here? First it tells me it has a +0 retain count and that is bad, then it tells me it has a +1 which is also bad. What can I do to ensure that I am either dealing with a Analyzer hiccup or that I release correctly? Thanks in advance

• How to use Git properly with XCode?

  - by rickharrison

  I have been an iphone developer for a while, and I have recently been including git in my workflow. I have used git settings found on http://shanesbrain.net/2008/7/9/using-xcode-with-git for my workflow so far. Those settings tell git to exclude *.pbxproj from merges? Is there a real reason for doing this? For example, when I add a file to the project and push to origin, my fellow developers will not have that file added to their xcode project when they pull. Then if one of them builds a release this file may not be included. Shouldn't I just let git handle the merges for the project file? Could someone please explain why or why not this file should be in merges and how to properly handle the situation when files are added to the project. Thanks.

• Why am I getting this warning about my app delegate and CLLocationManageDelegate?

  - by Dan Ray

  Observe this perfectly simple UIViewController subclass method: -(IBAction)launchSearch { OffersSearchController *search = [[OffersSearchController alloc] initWithNibName:@"OffersSearchView" bundle:nil]; EverWondrAppDelegate *del = [UIApplication sharedApplication].delegate; [del.navigationController pushViewController:search animated:YES]; [search release]; } On the line where I get *del, I am getting a compiler warning that reads, Type 'id <UIApplicationDelegate>' does not conform to the 'CLLocationManagerDelegate' protocol. In fact, my app delegate DOES conform to that protocol, AND what I'm doing here has nothing at all to do with that. So what's up with that message? Secondary question: sometimes I can get to my navigationController via self.navigationController, and sometimes I can't, and have to go to my app delegate's property to get it like I'm doing here. Any hint about why that is would be very useful.

• Memory management technique for Objective-C iVars/properties

  - by David Rea

  Is the following code doing anything unnecessary? @interface MyClass { NSArray *myArray; } -(void)replaceArray:(NSArray *)newArray; @implementation MyClass -(void)replaceArray:(NSArray *)newArray { if( myArray ) { [myArray release]; myArray = nil; } myArray = [[NSArray alloc] initWithArray: newArray]; } @end What if I made the following changes: 1) Made myArray a property: @property (nonatomic, retain) NSArray myArray; 2) Changed the assignment to: self.myArray = [NSArray arrayWithArray: newArray]; Would that allow me to remove the conditional?

• Trying to connect internally to Oracle, getting an idle instance?

  - by seanbseanbseanbseanb

  So I have an Oracle instance, and I know it's running on this system, I've su'd to the oracle user, and I'm trying to connect using "/ as sysdba". However, when I do connect, it says the instance is idle. I know the database is up and opened, because my application's talking to it. My paths (ORACLE_HOME, etc.) might be incorrect: any idea which incorrect setting might result in this? % sqlplus "/ as sysdba" SQL*Plus: Release 10.2.0.3.0 - Production on Mon Dec 8 09:23:22 2008 Copyright (c) 1982, 2006, Oracle.

• Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

  - by splicer

  I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

• Why is my CSS tool tip not functioning properly in Google Chrome, but fine in Firefox??

  - by JAG2007

  http://betawww.helpcurenow.org/media/press/ You'll see I have used spans within an anchor, with the span.hover-description set to display:none; by default, and on a:hover that span is set to display block and absolutely positioned to create a tool-tip effect when hovering over the name and email of the "For Immediate Release" contact names. Everything looks as desired in Firefox, but Chrome reveals my unknown blunder somewhere. Any help on what's the problem that is causing Chrome to not display like Firefox? Incidentally, Explorer shows the tool tip as expected, although I'm getting a funky bottom margin issue below the names, and Safari has the same issue as Chrome (must be a webkit rendering setting that I need to accommodate for).

• Rolling back or re-creating the master branch in git?

  - by Matthew Savage

  I have a git repo which has a few branches - there's the master branch, which is our stable working version, and then there is a development/staging branch which we're doing new work in. Unfortunately it would appear that without thinking I was a bit overzealous with rebasing and have pulled all of the staging code into Master over a period of time (about 80 commits... yes, I know, stupid, clumsy, poor code-man-ship etc....). Due to this it makes it very hard for me to do minor fixes on the current version of our app (a rails application) and push out the changes without also pushing out the 'staged' new features which we don't yet want to release. I am wondering if it is possible to do the following: Determine the last 'trunk' commit Take all commits from that point onward and move them into a separate branch, more or less rolling back the changes Start using the branches like they were made for. Unfortunately, though, I'm still continually learning about git, so I'm a bit confused about what to really do here. Thanks!

• Castle Windsor Controller Factory and RenderAction

  - by Bradley Landis

  I am running into an issue when using my Castle Windsor Controller Factory with the new RenderAction method. I get the following error message: A single instance of controller 'MyController' cannot be used to handle multiple requests. If a custom controller factory is in use, make sure that it creates a new instance of the controller for each request. This is the code in my controller factory: public class CastleWindsorControllerFactory : DefaultControllerFactory { private IWindsorContainer container; public CastleWindsorControllerFactory(IWindsorContainer container) { this.container = container; } public override IController CreateController(RequestContext requestContext, string controllerName) { return container.Resolve(controllerName) as IController; } public override void ReleaseController(IController controller) { this.container.Release(controller); } } Does anyone know what changes I need to make to make it work with RenderAction? I also find the error message slightly strange because it talks about multiple requests, but from what I can tell RenderAction doesn't actually create another request (BeginRequest isn't fired again).

• How to Use Eclipse to Debug JNI code (Java & C/C++)

  - by tkryger

  While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI Environments Mariot Chauvin's Summer of Code Project: Support Seamless Debugging between JDT & CDT Unfortunately, one claims to be pre-release quality and the other is currently unmaintained. Are there any plug-ins that bring mixed mode debugging functionality to Eclipse in a reliable way or should I continue to use two separate debuggers?

• Breakpoint pointing out "objc_autoreleaseNoPool"

  - by Andrew

  So I'm debugging an app in preperation for its app so release, and I enabled a universal breakpoint for "All Exceptions". Since then, everytime I run the app, the console prints: Catchpoint 2 (throw)Pending breakpoint 1 - "objc_exception_throw" resolved objc[11765]: Object 0x8f18ff0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f190a0 of class __NSCFNumber autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug objc[11765]: Object 0x8f1fef0 of class __NSCFLocale autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug Literally printed 3 times. I have no idea what this means but it looks bad. Any advice would be appreciated.

• Integrating TFS and MySQL

  - by user294043

  We are developing an application with Visual Studio 2008 and TFS. Our database is a MySQL DB. As we develop we keep the new queries that need to be applied to the database of our new release as the New Version Update Queries. Right now I'm keeping them in a simple text file (which is a painful task!). I know that TFS integrates with MSSQL and makes this job very easy. I've already asked our consultant from Microsoft if there is any way to integrate TFS and MySQL, and his answer was "NO". So I was wondering if anyone knows any smart way of handling this issue?

• Should I use C++0x Features Now?

  - by svu2g

  With the official release of VS 2010, is it safe for me to start using the partially-implemented C++0x feature set in my new code? The features that are of interest to me right now are both implemented by VC++ 2010 and recent versions of GCC. These are the only two that I have to support. In terms of the "safety" mentioned in the first sentence: can I start using these features (e.g., lambda functions) and still be guaranteed that my code will compile in 10 years on a compiler that properly conforms to C++0x when it is officially released? I guess I'm asking if there is any chance that VC++ 2010 or GCC will end up like VC++ 6; it was released before the language was officially standardized and consequently allowed grossly ill-formed code to compile. After all, Microsoft does say that "10 is the new 6". ;)

• TFS: Managing assembly version number?

  - by TomTom

  Hello, any good approach for managing assembly version numbers in TFS, possibly together with using the same number for the build number? I would be most interested in an approach that: Maintains the first three elements of the version Counts the rest upward for every "official" build (i.e. a build originating from certain templates only - no need to count up for something like a gated checkin, but the following regular integration build SHOULD count up. Labels the builds, so that a manual "release" build can be triggered. Any solution? How are other people handling this? Right now the (new) TFS is happily building with the same assembly version all around ;) Something coding the complete assembly version with date etc. is not acceptable - I want that number to "follow rules", and having the date in there is not one of them ;)

• unrecognized selector sent to instance

  - by iamsmug

  My app works fine in the simulator but when I run it on my phone I get this error: 2010-04-05 21:32:45.119 Top Banana[119:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[MethodViewController setReferringObject:]: unrecognized selector sent to instance 0x16e930' It happens here: -(void)method { [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.50]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO]; MethodViewController *methodViewController = [[MethodViewController alloc] initWithNibName:@"MethodViewController" bundle:0]; NSManagedObject *selectedObject = self.referringObject; methodViewController.referringObject = selectedObject; [self.navigationController pushViewController:methodViewController animated:NO]; methodViewController.title = @"Method"; [UIView commitAnimations]; [MethodViewController release]; } It crashes on this line: methodViewController.referringObject = selectedObject; Not sure how to resolve this as it works in the simulator, I'm sure it is fairly basic to fix, any help will be appreciated.

• Best Practice: Software Versioning

  - by Sebi

  I couldn't find a similar question here on SO, but if you find one please link. Is there any guideline or standard best practice how to version a software you develop in your spare time for fun, but nevertheless will be used by some people? I think it's necessary to version such software so that you know about with version one is talking about (e.g. for bug fixing, support, and so on). But where do I start the versioning? 0.0.0? or 0.0? And then how to I increment the numbers? major release.minor change? and should'nt any commit to a version control system be another version? or is this only for versions which are used in a productive manner?

• Will iPhone OS4 make your life easier or harder as a lone app developer?

  - by Matt

  I am interested to hear what people feel about the new iPhone OS4 release. It is obviously very exciting having access to all the new features, apparently (from apple.com) it has over 1500 new APIs. My original thoughts were "Wow, this is awesome", and I suppose it is. I was just getting comfortable with OS 3.2 development though, and now there is a raft of additional stuff to learn in order to keep up with the pack. So I am feeling quite frustrated! Do you think, when working as an individual app developer, having access to these additional features would improve your applications or just water down the quality? I guess being giving the opportunity to improve applications and provide better features should be welcomed. I think frustration comes from struggling to keep up with the continuous changes, but thats the industry we are in I suppose! Any thoughts/comments?

• Playing Ogg Sound in Android

  - by baba tenor

  In my application, I am trying to play a sound file in ogg format, stored in raw folder in res directory of my application. When I press the button that calls below function, it just freezes with the button pressed and does not respond. In the end, I have to terminate the application from Eclipse. Nothing about an error or exception in Logcat. In debugging mode, it enters create function and never comes back. What am I doing wrong? private void playbeep() { mPlayer = MediaPlayer.create(this, R.raw.beep); mPlayer.start(); mPlayer.release(); }

• iPhone: How do I override the back button in a Navigation Controller?

  - by Angelo Stracquatanio

  Hello, In my app I have a basic Navigation Controller. For all of my views, except one, the controller works as it should. However, for one view in particular, I would like the 'back' button to not go back to the previous view, but to go to one I set. In particular it is going to go back 2 views and skip over one. After doing some research I found that I can intercept the view when it disappears, so I tried to put in code to have it navigate to the page I would like: - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; //i set a flag to know that the back button was pressed if (viewPushed) { viewPushed = NO; } else { // Here, you know that back button was pressed mainMenu *mainViewController = [[mainMenu alloc] initWithNibName:@"mainMenu" bundle:nil]; [self.navigationController pushViewController:mainViewController animated:YES]; [mainViewController release]; } } That didn't work, so does anyone have any ideas? Thanks!!
