  • Converting to MVC3 - some views still want 'System.Web.Mvc, Version=1.0.0.0,

    - by justSteve
    I've used the directions from the release notes and have been able to navigate most pages - my unit tests are not comprehensive but most all pass. However...when I attempt to edit an existing or create a new user I'm getting the error pasted below - notice that it's references version=1... - this project started life as a v1 and was converted to mvc2 at the RTM. I'm still working with V2 projects but no longer any v1. Am i due for a GAC cleansing? Server Error in '/' Application.

  • Address book Phone number (+45) prefix causing crash!

    - by CCDEV
    Hi Guys... I am having trouble getting phone numbers from the iPhone Addressbook. There is no problem when the number do not contain a country code prefix like +45, but if it does, my app crashes... Is this a known issue? I haven't been able to find anything about it... Thanks EDIT: I get phonenumber like this: -(void)getContact { ABPeoplePickerNavigationController *pp = [[ABPeoplePickerNavigationController alloc] init]; pp.displayedProperties = [NSArray arrayWithObject:[NSNumber numberWithInt:kABPersonPhoneProperty]]; pp.peoplePickerDelegate = self; [self presentModalViewController:pp animated:YES]; [pp release]; } - (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker { // assigning control back to the main controller [self dismissModalViewControllerAnimated:YES]; } - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { return YES; } -(BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { ABMultiValueRef phoneProperty = ABRecordCopyValue(person,property); saveString = (NSString *)ABMultiValueCopyValueAtIndex(phoneProperty,identifier); saveString = [saveString stringByReplacingOccurrencesOfString:@" " withString:@""]; nummerTextField.text = saveString; }

  • Compiling scalafx for Java 7u7 (that contains JavaFX 2.2) on OS X

    - by akauppi
    The compilation instructions of scalafx says to do: export JAVAFX_HOME=/Path/To/javafx-sdk2.1.0-beta sbt clean compile package make-pom package-src However, with the new packaging of JavaFX as part of the Java JDK itself (i.e. 7u7 for OS X) there no longer seems to be such a 'javafx-sdkx.x.x' folder. The Oracle docs say that JavaFX JDK is placed alongside the main Java JDK (in same folders). So I do: $ export JAVAFX_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk $ sbt clean [warn] Using project/plugins/ (/Users/asko/Sources/scalafx/project/plugins) for plugin configuration is deprecated. [warn] Put .sbt plugin definitions directly in project/, [warn] .scala plugin definitions in project/project/, [warn] and remove the project/plugins/ directory. [info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins/project [info] Loading project definition from /Users/asko/Sources/scalafx/project/plugins [error] java.lang.NullPointerException [error] Use 'last' for the full log. Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? Am I doing something wrong or is scalafx not yet compatible with the latest Java release (7u7, JavaFX 2.2). What can I do? http://code.google.com/p/scalafx/ Addendum ..and finally (following Igor's solution below) sbt run launches the colorful circles demo easily (well, if one has a supported GPU that is). Oracle claims that "JavaFX supports graphic hardware acceleration on any Mac OS X system that is Lion or later" but I am inclined to think the NVidia powered Mac Mini I'm using does software rendering. A recent MacBook Air (core i7) is a complete different beast! :)

  • iPhone -trouble with a loading data from webservice into a tableview

    - by medampudi
    I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

  • Compiling a C++ application on Windows 7, but execute it on Win2003 Server

    - by dabs
    I have a C++ application (quite complex, multiple projects) in Visual Studio 2008, that produces a single dll. Recently I switched to Windows 7, but had previously been compiling under Windows XP. Suddenly the dll in question cannot be loaded by another application, i.e. on a machine running Windows 2003 Server. I've been trying various things: I've installed the VC9.0 redistributable package on the server Also copied various .dll's from that package to the application folder The project is of course compiled in release mode When I run depends.exe on the client machine, I do get the following error: "Error: The Side-by-Side configuration information for "my_dll.dll" contains errors. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem (14001). Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." and the icon for shlwapi.dll has a red overlay icon. This didn't happen when I was compiling under WinXP, so I'm guessing that there really is no problem with the .dll's on the client machine, but somewhere there is a reference to that particular version of some dll. Does anyone know what would be the best way to resolve this? Regards, Daníel

  • Loading more than 10 images on iPhone??

    - by SeniorLee
    I'm trying to add more than 10 pictures on ScrollView. NSUInteger i; for (i = 1; i <= numberOfImage; i++) { NSString *imageName = [NSString stringWithFormat:@"d%dimage%d.png", imageSection, i]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = kScrollObjHeight; rect.size.width = kScrollObjWidth; imageView.frame = rect; imageView.tag = i; // tag our images for later use when we place them in serial fashion [scrollView addSubview:imageView]; [imageView release]; } This code is from Apple example and it works fine. But if the variable 'i' is bigger than 10, 'UIImage *image' is empty. The imageName seems to correct. But I don't know why it does not load image. Does anybody sees the problem?? And one more thing. If I do like that, does iOS controls memory automatically? I mean it's kind of wasting memory if all (more than 10) images are loaded on memory even they are not displayed. I've heard that iOS loads images only displayed on screen and free images those are not displayed. Is that right? Thanks for reading.

  • Getting memory leak at NSURL connection in Iphone sdk.

  • Anyone Experiencing Slow Builds With VS2010?

    - by MrKWatkins
    Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

  • Android opengl releasing textures

    - by user1642418
    I have a bit of a problem. I am developing a game for android + engine and I got stuck. I am getting OpenGL out of memory error and either app crashes or phone hangs after loading a scene multiple times. For example: app launches, shows main menu, 1st level/scene is loaded. Then I go back to main menu, and repeat. It doesnt matter which scene I load, after 4-6 times the error occurs. Some background: Each time when scene is loaded all the resources are released and upon first frame render - needed stuff gets loaded. The performance is more or less ok. Note that I am calling glDeleteTexture method, but I think its not doing its job and releasing memory. Thing is that -when I minimize and open it again - problem doesn't occur, but almost the same things are executed. Problem doesn't occur. This way android releases memory. How do I release/get rid of unused textures properly? This happens on HTC Desire HD ( ice cream sandwich 4.0.4) . Other games works fine, so I bet this is not the problem in ROM.

  • Cocoa memory management - object going nil on me

    - by SirRatty
    Hi all, Mac OS X 10.6, Cocoa project, with retain/release gc I've got a function which: iterates over a specific directory, scans it for subfolders (included nested ones), builds an NSMutableArray of strings (one string per found subfolder path), and returns that array. e.g. (error handling removed for brevity). NSMutableArray * ListAllSubFoldersForFolderPath(NSString *folderPath) { NSMutableArray *a = [NSMutableArray arrayWithCapacity:100]; NSString *itemName = nil; NSFileManager *fm = [NSFileManager defaultManager]; NSDirectoryEnumerator *e = [fm enumeratorAtPath:folderPath]; while (itemName = [e nextObject]) { NSString *fullPath = [folderPath stringByAppendingPathComponent:itemName]; BOOL isDirectory; if ([fm fileExistsAtPath:fullPath isDirectory:&isDirectory]) { if (isDirectory is_eq YES) { [a addObject: fullPath]; } } } return a; } The calling function takes the array just once per session, keeps it around for later processing: static NSMutableArray *gFolderPaths = nil; ... gFolderPaths = ListAllSubFoldersForFolderPath(myPath); [gFolderPaths retain]; All appears good at this stage. [gFolderPaths count] returns the correct number of paths found, and [gFolderPaths description] prints out all the correct path names. The problem: When I go to use gFolderPaths later (say, the next run through my event loop) my assertion code (and gdb in Xcode) tells me that it is nil. I am not modifying gFolderPaths in any way after that initial grab, so I am presuming that my memory management is screwed and that gFolderPaths is being released by the runtime. My assumptions/presumptions I do not have to retain each string as I add it to the mutable array because that is done automatically, but I do have to retain the the array once it is handed over to me from the function, because I won't be using it immediately. Is this correct? Any help is appreciated.

  • How can I optimize this loop?

    - by Moshe
    I've got a piece of code that returns a super-long string that represents "search results". Each result is represented by a double HTML break symbol. For example: Result1<br><br>Result 2<br><br>Result3 I've got the following loop that takes each result and puts it into an array, stripping out the break indicator, "kBreakIndicator" (<br><br>). The problem is that this lopp takes way too long to execute. With a few results it's fine, but once you hit a hundred results, it's about 20-30 seconds slower. It's unacceptable performance. What can I do to improve performance? Here's my code: content is the original NSString. NSMutableArray *results = [[NSMutableArray alloc] init]; //Loop through the string of results and take each result and put it into an array while(![content isEqualToString:@""]){ NSRange rangeOfResult = [content rangeOfString:kBreakIndicator]; NSString *temp = (rangeOfResult.location != NSNotFound) ? [content substringToIndex:rangeOfResult.location] : nil; if (temp) { [results addObject:temp]; content = [[[content stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@%@", temp, kBreakIndicator] withString:@""] mutableCopy] autorelease]; }else{ [results addObject:[content description]]; content = [[@"" mutableCopy] autorelease]; } } //Do something with the results array. [results release];

  • How can I manage building library projects that produce both a static lib and a dll?

    - by Scott Langham
    I've got a large visual studio solution with ~50 projects. There are configurations for StaticDebug, StaticRelease, Debug and Release. Some libraries are needed in both dll and static lib form. To get them, we rebuild the solution with a different configuration. The Configuration Manager window is used to setup which projects need to build in which flavours, static lib, dynamic dll or both. This can by quite tricky to manage and it's a bit annoying to have to build the solution multiple times and select the configurations in the right order. Static versions need building before non-static versions. I'm wondering, instead of this current scheme, might it be simpler to manage if, for the projects I needed to produce both a static lib and dynamc dll, I created two projects. Eg: CoreLib CoreDll I could either make both of these projects reference all the same files and build them twice, or I'm wondering, would it be possible to build CoreLib and then get CoreDll to link it to generate the dll? I guess my question is, do you have any advice on how to structure your projects in this kind of situation? Thanks.

  • Best way to build an application based on R?

    - by Prasad Chalasani
    I'm looking for suggestions on how to go about building an application that uses R for analytics, table generation, and plotting. What I have in mind is an application that: displays various data tables in different tabs, somewhat like in Excel, and the columns should be sortable by clicking. takes user input parameters in some dialog windows. displays plots dynamically (i.e. user-input-dependent) either in a tab or in a new pop-up window/frame Note that I am not talking about a general-purpose fron-end/GUI for exploring data with R (like say Rattle), but a specific application. Some questions I'd like to see addressed are: Is an entirely R-based approach even possible ( on Windows ) ? The following passage from the Rattle article in R-Journal intrigues me: It is interesting to note that the first implementation of Rattle actually used Python for implementing the callbacks and R for the statistics, using rpy. The release of RGtk2 allowed the interface el- ements of Rattle to be written directly in R so that Rattle is a fully R-based application If it's better to use another language for the GUI part, which language is best suited for this? I'm looking for a language where it's relatively "painless" to build the GUI, and that also integrates very well with R. From this StackOverflow question How should I do rapid GUI development for R and Octave methods (possibly with Python)? I see that Python + PyQt4 + QtDesigner + RPy2 seems to be the best combo. Is that the consensus ? Anyone have pointers to specific (open source) applications of the type I describe, as examples that I can learn from?

  • Any techniques to interrupt, kill, or otherwise unwind (releasing synchronization locks) a single de

    - by gojomo
    I have a long-running process where, due to a bug, a trivial/expendable thread is deadlocked with a thread which I would like to continue, so that it can perform some final reporting that would be hard to reproduce in another way. Of course, fixing the bug for future runs is the proper ultimate resolution. Of course, any such forced interrupt/kill/stop of any thread is inherently unsafe and likely to cause other unpredictable inconsistencies. (I'm familiar with all the standard warnings and the reasons for them.) But still, since the only alternative is to kill the JVM process and go through a more lengthy procedure which would result in a less-complete final report, messy/deprecated/dangerous/risky/one-time techniques are exactly what I'd like to try. The JVM is Sun's 1.6.0_16 64-bit on Ubuntu, and the expendable thread is waiting-to-lock an object monitor. Can an OS signal directed to an exact thread create an InterruptedException in the expendable thread? Could attaching with gdb, and directly tampering with JVM data or calling JVM procedures allow a forced-release of the object monitor held by the expendable thread? Would a Thread.interrupt() from another thread generate a InterruptedException from the waiting-to-lock frame? (With some effort, I can inject an arbitrary beanshell script into the running system.) Can the deprecated Thread.stop() be sent via JMX or any other remote-injection method? Any ideas appreciated, the more 'dangerous', the better! And, if your suggestion has worked in personal experience in a similar situation, the best!

  • Help: List contents of iPhone application bundle subpath??

    - by bluepill
    Hi, I am trying to get a listing of the directories contained within a subpath of my application bundle. I've done some searching and this is what I have come up with - (void) contents { NSArray *contents = [[NSBundle mainBundle] pathsForResourcesOfType:nil inDirectory:@"DataDir"]; if (contents = nil) { NSLog(@"Failed: path doesn't exist or error!"); } else { NSString *bundlePathName = [[NSBundle mainBundle] bundlePath]; NSString *dataPathName = [bundlePathName stringByAppendingPathComponent: @"DataDir"]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSMutableArray *directories = [[NSMutableArray alloc] init]; for (NSString *entityName in contents) { NSString *fullEntityName = [dataPathName stringByAppendingPathComponent:entityName]; NSLog(@"entity = %@", fullEntityName); BOOL isDir = NO; [fileManager fileExistsAtPath:fullEntityName isDirectory:(&isDir)]; if (isDir) { [directories addObject:fullEntityName]; NSLog(@" is a directory"); } else { NSLog(@" is not a directory"); } } NSLog(@"Directories = %@", directories); [directories release]; } } As you can see I am trying to get a listing of directories in the app bundle's DataDir subpath. The problem is that I get no strings in my contents NSArray. note: - I am using the simulator - When I manually look in the .app file I can see DataDir and the contents therein - The contents of DataDir are png files and directories that contain png files - The application logic needs to discover the contents of DataDir at runtime - I have also tried using NSArray *contents = [fileManager contentsOfDirectoryAtPath:DataDirPathName error:nil]; and I still get no entries in my contents array Any suggestions/alternative approaches? Thanks.

  • iPhone - sorting the results of a core data entity

    - by Digital Robot
    I have a core data entity that represents the attributes of a product, as number, price, etc. The product number is a NSString property and follows the form X.y where X is a number variable of digits and Y is one digit. For example. 132.2, 99.4, etc. I am querying the database to obtain the list of product numbers in order: The code is like this: + (NSArray*)todosOsItens:(NSString *)pName inManagedObjectContext:(NSManagedObjectContext *)context { Product *aProduct = [Product productWithName:pName inManagedObjectContext:context]; NSArray *all = nil; NSFetchRequest *request = [[NSFetchRequest alloc] init]; request.entity = [NSEntityDescription entityForName:@"Attributes" inManagedObjectContext:context]; request.predicate = [NSPredicate predicateWithFormat: @"(belongsTo == %@)", aProduct]; [request setResultType:NSDictionaryResultType]; [request setReturnsDistinctResults:YES]; [request setPropertiesToFetch:[NSArray arrayWithObject:item]]; NSSortDescriptor *sortByItem = [NSSortDescriptor sortDescriptorWithKey:@"ProductNumber" ascending:YES]; NSArray *sortDescriptors = [NSArray arrayWithObject:sortByItem]; [request setSortDescriptors:sortDescriptors]; NSError *error = nil; all = [[context executeFetchRequest:request error:&error] mutableCopy]; [request release]; return all; } but this query is not returning the sorted results. The results are coming on their natural order on the database. How do I do that? thanks.

  • How to determine if the camera button is half pressed

    - by Matthew
    I am creating a small test camera application, and I would like to be able to implement a feature that allows focus text bars to be present on the screen while the hardware camera button is pressed half way down. I created a camera_ButtonHalfPress event to perform the focus action, but I am unsure of how to toggle the text bars I would like to show on the screen accordingly. Essentially, my goal would be to show the text bars while the camera button is pressed half way down, and then remove them if the button is pressed all the way or the button is released before being pressed all the way down. The button being released is the part I am having trouble with. What I have is as follows: MainPage.xaml.cs private void camera_ButtonHalfPress(object sender, EventArgs e) { //camera.Focus(); // Show the focus brackets. focusBrackets.Visibility = Visibility.Visible; } } private void camera_ButtonFullPress(object sender, EventArgs e) { // Hide the focus brackets. focusBrackets.Visibility = Visibility.Collapsed; camera.CaptureImage(); } } Currently, if the the user decides to release the camera button before it is pressed all the way, the focus brackets persist on the screen. How might I fix this issue?

  • Facebook connect with iPhone not working?

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to use Facebook connect in my application, but its not working as I desire. When I am trying to use the API Key and the API SecretKey of my application which I have registered with the facebook its not working. I have downloaded the code for the facebook. In the SessionViewController.m file when I pass my key values its not working. What I am trying to achieve is, when the app launches the first page is the Facebook Login Page. The user enters his username and password and then the next view should display. But nothing is happening, even the label doesn't display the username. Heres the code which I am using - (void)request:(FBRequest*)request didLoad:(id)result { NSArray* users = result; NSDictionary* user = [users objectAtIndex:0]; NSString* name = [user objectForKey:@"name"]; _label.text = [NSString stringWithFormat:@"Logged in as %@",name]; NSLog(@"Username is :- %@",name); FrontController *main = [[FrontController alloc] init]; [self.view addSubview:main.view]; [main release]; } I am not able to figure out what is wrong with this code. When I try with some other key values such as the key for connect application its working fine. Can anyone help me with this... Thanx in advance...

  • How to manage large amounts of delegates and usercallbacks in C# async http library

    - by Tyler
    I'm coding a .NET library in C# for communicating with XBMC via its JSON RPC interface using HTTP. I coded and released a preliminary version but everything is done synchronously. I then recoded the library to be asynchronous for my own purposes as I was/am building an XBMC remote for WP7. I now want to release the new async library but want to make sure it's nice and tidy before I do. Due to the async nature a user initiates a request, supplies a callback method that matches my delegate and then handles the response once it's been received. The problem I have is that within the library I track a RequestState object for the lifetime of the request, it contains the http request/response as well as the user callback etc. as member variables, this would be fine if only one type of object was coming back but depending on what the user calls they may be returned a list of songs or a list of movies etc. My implementation at the moment uses a single delegate ResponseDataRecieved which has a single parameter which is a simple Object - As this has only be used by me I know which methods return what and when I handle the response I cast said object to the type I know it really is - List, List etc. A third party shouldn't have to do this though - The delegate signature should contain the correct type of object. So then I need a delegate for every type of response data that can be returned to the third party - The specific problem is, how do I handle this gracefully internally - Do I have a bunch of different RequestState objects that each have a different member variable for the different delegates? That doesn't "feel" right. I just don't know how to do this gracefully and cleanly.

  • Releasing from development into production in maven

    - by Bruce
    Hi all, I'm confused about the use of maven in development and production environments - I'm sure it's something simple that I'm missing. Grateful for any help.. I set up maven inside eclipse on my local machine and wrote some software. I really like how it's made things like including dependent jars very easy. So that's my development environment. But now I want to release the project to production on a remote server. I've searched the documentation, but I can't figure out how it's supposed to work or what the maven best practice is.. Are you supposed to: a) Also be running maven on your production environment, and upload all your files to your production environment and rebuild your project there? (Something in me baulks at the idea of rebuilding 'released' code on the production server, so I'm fairly sure this isn't right..) b) use mvn:package to create your jar file and then copy that up to production? (But then what of all those nice dependencies? Isn't there a danger that your tested code is now going to be running against different versions of the dependent jars in the production environment, possibly breaking your code? Or missing a jar..?) c) Something else that I'm not figuring out.. Thanks in advance for any help!

  • Problem in calling a function from different class using protocols-iphone

    - by Muniraj
    I use cocos2d for my game. In which I play a movie and have a separate overlay view for controls.The touches are detected in the overlay view. Now when the touches are detected the function in the game code has to be invoked. But the function is not detected and there is no error. I dont know what has gone wrong. Someone please help me. The code are as follows The protocol part is @protocol Protocol @required -(void) transition1:(id) sender; @end The function which is to be invoked in the game code is (void) transition1:(id) sender { [[Director sharedDirector] replaceScene: [ [Scene node] addChild: [Layer4 node] z:0] ]; } The code in the overlay view in MovieOverlayViewController.h import "Protocol.h" @interface MovieOverlayViewController : UIViewController { UIImageView *overlay; NSObject <Protocol> *transfer; } @end The code in the overlay view in MovieOverlayViewController.m @implementation MovieOverlayViewController (id)init { if ((self = [super init])) self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]; return self; } -(void) viewWillAppear:(BOOL)animated { overlay = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"overlay.png"]] autorelease]; [self.view addSubview:overlay]; } (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint point = [touch locationInView:self.view]; NSLog(@"pointx: %f pointy:%f", point.x, point.y); if (CGRectContainsPoint(CGRectMake(1, 440, 106, 40), point)) { // the function is called here [transfer transition1: nil]; } else if (CGRectContainsPoint(CGRectMake(107, 440, 106, 40), point)) NSLog(@"tab 2 touched"); } (void)dealloc { [overlay release]; [super dealloc]; } @end

  • EXC_BAD_ACCESS in NSURLConnection: how to debug?

    - by baswell
    I have an iPhone app that downloads URLs. (PDFs to display) Easy: self.conn = [NSURLConnection connectionWithRequest:self.request delegate:self]; where self.conn is a retained property. For specific URLs, this throws EXC_BAD_ACCESS. The URL is valid and is constructed in the same way as URLs that do work. (90% of URLs are fine) These ones work: http://www.airservicesaustralia.com/publications/current/ersa/FAC_YARG_11-Mar-2010.pdf http://www.airservicesaustralia.com/publications/current/ersa/FAC_YARK_11-Mar-2010.pdf These don't: http://www.airservicesaustralia.com/publications/current/ersa/FAC_YAMK_11-Mar-2010.pdf http://www.airservicesaustralia.com/publications/current/ersa/FAC_YATN_11-Mar-2010.pdf Spot the difference? Yeah, me neither. Also no difference in response headers from the server for them. To clarify, the ones that work ALWAYS work, the ones that don't NEVER work. So not some random release/retain issue it seems. For the ones that don't work, none of the methods in my delegate are ever called, it fails hard before that. And with no error message, just EXC_BAD_ACCESS. Sooo.... Any way to debug what is going on inside NSURLConnection?

  • How can I copy files in the middle of a build in Team System?

    - by Dana
    I have two solutions that I want to include in a build. Solution two requires the dll's from solution one to successfully build. Solution two has a Binaries folder where the dll's from solution one need to be copied before building Solution two. I've been trying an AfterBuild Target, hoping that it would copy the items after the first SolutionToBuild, but it doesn't fire then. I'm guessing that it would probably fire after both solutions have compiled, but that's not what I want. <SolutionToBuild Include="$(BuildProjectFolderPath)/../../Main/Framework.sln"> <Targets>AfterCompileFramework</Targets> <Properties></Properties> </SolutionToBuild> <SolutionToBuild Include="$(BuildProjectFolderPath)/../../../Dashboard/Main/Dashboard.sln"> <Targets></Targets> <Properties></Properties> </SolutionToBuild> <ItemGroup> <FrameworkBinaries Include="$(DropLocation)\$(BuildNumber)\Release\Framework.*.dll"/> </ItemGroup> <Message Text="FrameworkBinaries: @(FrameworkBinaries)" Importance="high"/> <Copy SourceFiles="@(FrameworkBinaries)" DestinationFolder="$(BuildProjectFolderPath)/../../../Dashboard/Main/Binaries"/>
