• Why am I getting "Message sent to deallocated instance" in Objective-C?

  - by Dave C

  I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag (int value) is parsed into the controller's house ID. It works with one of the buttons — the first one created, to be specific — but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code. I haven't set them to autorelease or anything like that. I'm just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++;

• How can I store large amount of data from a database to XML (memory problem)?

  - by Andrija

  First, I had a problem with getting the data from the Database, it took too much memory and failed. I've set -Xmx1500M and I'm using scrolling ResultSet so that was taken care of. Now I need to make an XML from the data, but I can't put it in one file. At the moment, I'm doing it like this: while(rs.next()){ i++; xmlStringBuilder.append("\n\t<row>"); xmlStringBuilder.append("\n\t\t<ID>" + Util.transformToHTML(rs.getInt("id")) + "</ID>"); xmlStringBuilder.append("\n\t\t<JED_ID>" + Util.transformToHTML(rs.getInt("jed_id")) + "</JED_ID>"); xmlStringBuilder.append("\n\t\t<IME_PJ>" + Util.transformToHTML(rs.getString("ime_pj")) + "</IME_PJ>"); //etc. xmlStringBuilder.append("\n\t</row>"); if (i%100000 == 0){ //stores the data to a file with the name i.xml storeKBR(xmlStringBuilder.toString(),i); xmlStringBuilder= null; xmlStringBuilder= new StringBuilder(); } and it works; I get 12 100 MB files. Now, what I'd like to do is to do is have all that data in one file (which I then compress) but if just remove the if part, I go out of memory. I thought about trying to write to a file, closing it, then opening, but that wouldn't get me much since I'd have to load the file to memory when I open it. P.S. If there's a better way to release the Builder, do let me know :)

• NSTimer Reset Not Working

  - by user355900

  hi, i have a nstimer and it works perfectly counting down from 2:00 but when i hit the reset button it does not work it just stops the timer and when i press start again it will carry on with the timer as if it had never been stopped. Here is my code `@implementation TimerAppDelegate @synthesize window; (void)applicationDidFinishLaunching:(UIApplication *)application { timerLabel.text = @"2:00"; seconds = 120; // Override point for customization after application launch [window makeKeyAndVisible]; } (void)viewDidLoad { [timer invalidate]; } (void)countDownOneSecond { seconds--; int currentTime = [timerLabel.text intValue]; int newTime = currentTime - 1; int displaySeconds = !(seconds % 60) ? 0 : seconds < 60 ? seconds : seconds - 60; int displayMinutes = floor(seconds / 60); NSString *time = [NSString stringWithFormat:@"%d:%@%d", displayMinutes, [[NSString stringWithFormat:@"%d", displaySeconds] length] == 1 ? @"0" : @"", displaySeconds ]; timerLabel.text = time; if(seconds == 0) { [timer invalidate]; } } (void)startOrStopTimer { if(timerIsRunning){ [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; } else { timer = [[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDownOneSecond) userInfo:nil repeats:YES] retain]; [startOrStopButton setTitle:@"Stop" forState:UIControlStateNormal]; } timerIsRunning = !timerIsRunning; } (void)resetTimer { [timer invalidate]; [startOrStopButton setTitle:@"Start" forState:UIControlStateNormal]; [timer invalidate]; timerLabel.text = @"2:00"; } (void)dealloc { [window release]; [super dealloc]; } @end` thanks

• Visual Studio 2008 Installer, Custom Action. Breakpoint not firing.

  - by Snake

  Hi, I've got an installer with a custom action project. I want the action to fire at install. The action fires, when I write something to the event log, it works perfectly. But I really need to debug the file since the action is quite complicated. So I've got the following installer class: namespace InstallerActions { using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Configuration.Install; using System.Diagnostics; using System.IO; [RunInstaller(true)] // ReSharper disable UnusedMember.Global public partial class DatabaseInstallerAction : Installer // ReSharper restore UnusedMember.Global { public DatabaseInstallerAction() { InitializeComponent(); } public override void Install(IDictionary stateSaver) { base.Install(stateSaver); System.Diagnostics.Debugger.Launch(); System.Diagnostics.Debugger.Break(); // none of these work Foo(); } private static void Foo() { } } } The installer just finalizes without warning me, it doesn't break, it doesn't ask me to attach a debugger. I've tried debug and release mode. Am I missing something? Thanks -Snake

• UITableView superClass for delegate?

  - by fuzzygoat

  A quick question, I am setting a delegate for UITableView and I have a question regarding setting the delegate and dataSource properties. I have noticed that the properties for delegate and dataSource are not available, I was thinking that adopting the protocols would make them available. But I am now thinking that I maybe have the superclass for my delegate class wrong. Currently I have: -(void)viewDidLoad { TestDelegate *tempDelegate = [[TestDelegate alloc] init]; [self setMyDelegate:tempDelegate]; // setDelegate // setDataSource [tempDelegate release]; [super viewDidLoad]; } My interface for TestDelegate looks like: @interface TestDelegate : NSObject <UITableViewDelegate, UITableViewDataSource> { NSArray *listData; int myCounter; } Can I ask if the above should be: @interface TestDelegate : UITableView <UITableViewDelegate, UITableViewDataSource> { NSArray *listData; int myCounter; } gary EDIT: I think it might be right as NSObject, I have a viewtableView in IB, thats what I will need to connect my delegate class to. I added to tableView in IB so maybe I just need to make it available in Xcode.

• Where do I attach the StoreKit delegate and observer in a Cocos2d App?

  - by Jeff B

  I have figured out how all of the StoreKit stuff works and have actually tested working code... however, I have a problem. I made my "store" layer/scene the SKProductsRequestDelegate. Is this the correct thing to do? I get the initial product info like so: SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers: productIDs]; [productRequest setDelegate: self]; [productRequest start]; The problem is that if I transition to a new scene when a request is in progress, the current layer is retained by the productRequest. This means that touches on my new scene/layer are handled by both the new layer and the old layer. I could cancel the productRequest when leaving the scene, but: I do not know if it is in progress at that point. I cannot release it because it may or may not have been released by the request delegates. There has got to be a better way to do this. I could make the delegate a class external to the current layer, but then I do not know how to easily update the layer with the product information when the handler is called.

• [Adobe Air] Can I catch a mouseUp event of an mx:Window that did not fire hte mouseDown?

  - by Irene

  Hi, In an AIR application, I have one mx:TileList with several images. What I need to do is let the user drag and drop one of the images on the desktop, giving a feeling of a desktop widget. Firstly I tried to implement this using dragStart etc, but in the end I think it is easier to handle mouseDown and mouseUp on the TileList. In general the whole setup works as desired. When a mouseDown is detected on the TileList, I create a transparent mx:Window containing the corresponding image, and call the startMove() on the Window to simulate a dragging behavior. If I release the mouse, the Window stops moving as desired. My problem is that now I want some visual feedback during dragging. It works while the Window is moving, however I can't find a way to stop it when the user releases the mouse. The mouseUp is not fired from the TileList, nor from the s:WindowedApplication. I also tried to add a listener to the Window itself, but still with no luck. Some code: private function onMouseDown(e:MouseEvent):void { trace ("down " + e.target); if (e.target is TileListItemRenderer) { // first create a dragWindow dragWindow.startGlow(); // then show some visual feedback dragWindow.moveWindow(e); // and start dragging } } private function onMouseUp(e:MouseEvent):void { trace("up " + e.target); dragWindow.stopGlow(); // <--------- Not called! } <mx:TileList id="photoTileList" mouseDown="onMouseDown(event)" mouseUp="onMouseUp(event)">

• Unable to pass variables from one view to another

  - by jerincbus

  I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.address = self.address; mapController.Title = self.Title; mapController.lat = self.lat; mapController.lng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; mapController = nil; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

• How to set interface method between two viewController to pass paramter in Navigation Controller

  - by TechFusion

  Hello, I have created Window based application, root controller as Tab Bar controller. One Tab bar has Navigation controller. Navigation controller's ViewControlller implementation, I am pushing Viewcontroller. I am looking to pass parameter from Navigation Controller's View controller to pushed View Controller. I have tried to pass as per below method. //ViewController.h @interface ViewController:UIViewController{ NSString *String; } @property(copy, nonatomic)NSString *String; @end //ViewController.m #import "ViewController1.h" ViewController1 *level1view = [[ViewController alloc]init]; level1view.hideBottomBarWhenPushed = YES; level1view.theString = String; [self.navigationController pushViewController:level1view animated:YES]; [level1view release]; //ViewController1.h NSString *theString; @property(copy, nonatomic)NSString *theString; This is working fine. but I want to pass more than one parameter like Integer and UITextFiled Values so how to do that? Is there any Apple Doc that I can get idea about this? Thanks,

• .NET MissingMethodException occuring on one of thousands of end-user machines -- any insight?

  - by Yoooder

  This issue has me baffled, it's affecting a single user (to my knowledge) and hasn't been reproduced by us... The user is receiving a MissingMethodException, our trace file indicates it's occuring after we create a new instance of a component, when we're calling an Initialize/Setup method in preparation to have it do work (InitializeWorkerByArgument in the example) The Method specified by the error is an interface method, which a base class implements and classes derived from the base class can override as-needed The user has the latest release of our application All the provided code is shipped within a single assembly Here's a very distilled version of the component: class Widget : UserControl { public void DoSomething(string argument) { InitializeWorkerByArgument(argument); this.Worker.DoWork(); } private void InitializeWorkerByArgument(string argument) { switch (argument) { case "SomeArgument": this.Worker = new SomeWidgetWorker(); break; } // The issue I'm tracking down would have occured during "new SomeWidgetWorker()" // and would have resulted in a missing method exception stating that // method "DoWork" could not be found. this.Worker.DoWorkComplete += new EventHandler(Worker_DoWorkComplete); } private IWidgetWorker Worker { get; set; } void Worker_DoWorkComplete(object sender, EventArgs e) { MessageBox.Show("All done"); } } interface IWidgetWorker { void DoWork(); event EventHandler DoWorkComplete; } abstract class BaseWorker : IWidgetWorker { virtual public void DoWork() { System.Threading.Thread.Sleep(1000); RaiseDoWorkComplete(this, null); } internal void RaiseDoWorkComplete(object sender, EventArgs e) { if (DoWorkComplete != null) { DoWorkComplete(this, null); } } public event EventHandler DoWorkComplete; } class SomeWidgetWorker : BaseWorker { public override void DoWork() { System.Threading.Thread.Sleep(2000); RaiseDoWorkComplete(this, null); } }

• When to drop an IT job

  - by Nippysaurus

  In my career I have had two programming jobs. Both these jobs were in a field that I am most familiar with (C# / MSSQL) but I have quit both jobs for the same reason: unmanageable code and bad (loose) company structure. There was something in common with both these jobs: small companies (in one I was the only developer). Currently I am in the following position: being given written instructions which are almost impossible to follow (somewhat of a fools errand). we are given short time constraints, but seldom asked how long work will take, and when we do it is always too long and needs to be shorter (and when it ends up taking longer than they need it to take, it's always our fault). there is no time for proper documenting, but we get blamed for not documenting (see previous point). Management is constantly screwing me around, saying I'm underperforming on a given task (which is not true, and switching me to a task which is much more confusing). So I must ask my fellow developers: how bad does a job need to be before you would consider jumping ship? And what to look out for when considering taking a job. In future I will be asking about documented procedures, release control, bug management and adoption of new technologies. EDIT: Let me add some more fuel to the fire ... I have been in my current job for just over a year, and the work I am doing almost never uses any of the knowledge I have gained from the other work I have been doing here. Everything is a giant learning curve. Because of this about 30% of my time is learning what is going on with this new product (who's owner / original developer has left the company), 30% trying to find the relevant documentation that helps the whole thing make sense, 30% actually finding where to make the change, 10% actually making the change.

• How to add images while moving finger across UIView?

  - by Luke Irvin

  I am having issues adding an image across a view while moving finger across the screen. Currently it is adding the image multiple times but squeezing them too close together and not really following my touch. Here is what I am trying: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; touchPoint = [touch locationInView:imageView]; if (touchPoint.x > 0 && touchPoint.y > 0) { _aImageView = [[UIImageView alloc] initWithImage:aImage]; _aImageView.multipleTouchEnabled = YES; _aImageView.userInteractionEnabled = YES; [_aImageView setFrame:CGRectMake(touchPoint.x, touchPoint.y, 80.0, 80.0)]; [imageView addSubview:_aImageView]; [_aImageView release]; } } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesBegan:touches withEvent:event]; } Any suggestions is much appreciated. EDIT: What I want: After taking or choosing an image, the user can then select another image from a list. I want the user to touch and move their finger across the view and the selected image will appear where they drag their finger, without overlapping, in each location.

• Bind a ViewModel to a DropDownListFor with a third value besides dataValueField/dataTextField

  - by Elisa

  When I show a list of testplanViewModels in my View and the user selects one the SelectedTestplanId is returned to the Controller post action. What should also be returned is the TemplateId which belongs to the SelectedTestplanId. When the AutoMapper definition is run the Testplan.TestplanId is implicitly copied over to the TestplanViewModel.TestplanId. The same could be done by providing a TemplateId on the TestplanViewModel. When the user selects now a "TestplanViewModel" in the View, how can I attach the TemplateId to the controller action to access it there? The DropDownList does not allow 2 dataValueFields! CreateMap<Testplan, TestplanViewModel>().ForMember(dest => dest.Name, opt => opt.MapFrom(src => string.Format("{0}-{1}-{2}-{3}", src.Release.Name, src.Template.Name, src.CreatedAt, src.CreatedBy))); public ActionResult OpenTestplanViewModels() { IEnumerable<Testplan> testplans = _testplanDataProvider.GetTestplans(); var viewModel = new OpenTestplanViewModel { DisplayList = Mapper.Map<IEnumerable<Testplan>, IEnumerable<TestplanViewModel>>(testplans) }; return PartialView(viewModel); } public class TestplanViewModel { public int TestplanId { get; set; } public string Name { get; set; } } public class OpenTestplanViewModel { [Required(ErrorMessage = "No item selected.")] public int SelectedTestplanId { get; set; } public IEnumerable<TestplanViewModel> DisplayList { get; set; } } OpenTestplanViewModel @using (Html.BeginForm("Open", "Testplan")) { @Html.ValidationSummary(false) @Html.DropDownListFor(x => x.SelectedTestplanId, new SelectList(Model.DisplayList, "TestplanId", "Name"), new { @class = "listviewmodel" }) }

• iPhone - Problem with in-app purchases

  - by Satyam svv

  I've created iPhone app with in-app purchase. Now, I'm in testing phase. I created provisioning profile com.satyam.testapp In iTunes connected I created the application and uploaded the images, screen shots, desscription etc. I also created two id's for in-app purchase. One is com.satyam.testapp.book1 and the other one is com.satyam.testapp.book5 I created test account also for verifying my in-app purchases. Using com.stayam.testapp i created developer test profile and using the same in my developed application. I logged out the itunes app store account in my iphone. Now i started running my application on my iphone. Its saying that no items are there to purchase. But its not even asking me for credentials where i've to enter test account username and password..... how to debug it? Here's my delegate: - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { NSArray *myProduct = [[NSArray alloc] initWithArray:response.products]; for(int i=0;i<[myProduct count];i++) { SKProduct *product = [myProduct objectAtIndex:i]; NSLog(@"Name: %@ - Price: %f",[product localizedTitle],[[product price] doubleValue]); NSLog(@"Product identifier: %@", [product productIdentifier]); } for(NSString *invalidProduct in response.invalidProductIdentifiers) NSLog(@"Problem in iTunes connect configuration for product: %@", invalidProduct); [request autorelease]; [myProduct release]; }

• how to merge ecommerce transaction data between two databases

  - by yamspog

  We currently run an ecommerce solution for a leisure and travel company. Everytime we have a release, we must bring the ecommerce site down as we update database schema and the data access code. We are using a custom built ORM where each data entity is responsible for their own CRUD operations. This is accomplished by dynamically generating the SQL based on attributes in the data entity. For example, the data entity for an address would be... [tableName="address"] public class address : dataEntity { [column="address1"] public string address1; [column="city"] public string city; } So, if we add a new column to the database, we must update the schema of the database and also update the data entity. As you can expect, the business people are not too happy about this outage as it puts a crimp in their cash-flow. The operations people are not happy as they have to deal with a high-pressure time when database and applications are upgraded. The programmers are upset as they are constantly getting in trouble for the legacy system that they inherited. Do any of you smart people out there have some suggestions?

• Problem of Sprites and labels are displayed by white boxes.

  - by srikanth rongali

  I am writing a game in cocos2d. I am using a function restartDirector in AppDelegate class. -(void)restartDirector{ [[CCDirector sharedDirector] end]; [[CCDirector sharedDirector] release]; if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:CCDirectorTypeDefault]; [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888]; [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; [[CCDirector sharedDirector] setDeviceOrientation:CCDeviceOrientationLandscapeLeft]; [[CCDirector sharedDirector] attachInView:window]; } This function I called in one of the game Scene . -(void)PracticeMethod:(id)sender { [MY_DELEGATE restartDirector]; CCScene *endPageScene = [CCScene node]; CCLayer *endPageLayer = [DummyScene node]; [endPageScene addChild:endPageLayer]; [[CCDirector sharedDirector] runWithScene:endPageScene]; // [[CCDirector sharedDirector] replaceScene:endPageScene]; } When used the replaceScene, there is no problem in game but the memory of abject allocation is high(I checked in leaks tool). So I used runWithScene. But , while using these when the scene DummyScene is loaded the sprites, labels in it are displayed by white boxes. I cannot see the sprites and labels. If I am using replaceScene everything thing is working fine but the memory allocation is high. this is my problem. Thank you.

• Powershell finding services using a cmdlet dll

• Hibernate not saving foreign key, but with junit it's ok

  - by Leonardo

  Hi All, I have this strange problem. In a J2ee webapp with spring, smartgwt and hibernate, it happens that I have a class A wich has a set of class B, both of them mapped to table A and table B. I wrote a simple test case for testing the service manager which is supposed to do insert, update, delete and everything work as expected especially during insert. In the end I have one record in A and records in B with foreign key to A. But when I try to call the service from the web app, the entity in B are saved without a foreign key reference. I am sure that the service is the same. One thing I noticed is that enabling hibernate logging, seems that when the service is called from the application, one more update is made: insert A insert B update A update B update B (foreign key only) update A <--- ??? update B <--- ??? Instead, when junit test case is run, the update is as follows: insert A insert B update A update B update B (foreign key only) I suppose the latest update is what is causing the erroe, maybe it is overwriting values. Considering that the app is using spring, with the well known mechanism of DAO + Manager, where can I investigate to solve this issue ? Someone told me that the session is not closed, so hibernate would do one more update before release the objects by itself. I am pretty sure that all the configuration hbm, xml, and the rest are fine...but I maybe wrong. thanks

• delegate method throws runtime "unrecognized selector" error when switching back from one UIViewCont

  - by chimgrrl

  Ok, I've spend like half day on this and it's killing me. So I've got 3 view controllers transitioning from one another, something like this: I call the UploadDecisionViewController after destroying the previous View Controller: [self dismissModalViewControllerAnimated:YES]; [self performSelector:@selector(showUDModalView) withObject:nil afterDelay:0.5]; In my showUDModalView method: - (void)showUDModalView { UploadDecisionViewController *udcontroller = [[UploadDecisionViewController alloc] initWithNibName:@"UploadDecisionViewController" bundle:nil]; udcontroller.delegate = self; [self presentModalViewController:udcontroller animated:YES]; [udcontroller release]; } The UploadDecisionViewController shows up no problem. The UploadDecisionViewController has a button, which when clicked I want it to transition to the FileUploadViewController. I setup a UploadDecisionDelegate, threw a method in there to handle the button clicking: Inside UploadDecisionDelegate protocol (UploadDecisionViewController.h): @protocol UploadDecisionDelegate //let UOnliveViewController know that a button was selected - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection; @end Then inside my IBAction method when the button is clicked, I have this: - (IBAction)decisionSelected:(id)sender { [delegate UploadDecisionViewController:self madeChoice:@"upload"];//crashing at this line } When I run this, at this line above it is throwing a runtime exception: 2010-06-09 12:48:59.561 UOnlive[4735:207] *** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420 2010-06-09 12:48:59.562 UOnlive[4735:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView UploadDecisionViewController:madeChoice:]: unrecognized selector sent to instance 0x3b65420' 2010-06-09 12:48:59.563 UOnlive[4735:207] Stack: ( 33502299, 2495698185, 33884219, 33453686, 33306306, 20618, 2982917, 3390286, 3399023, 3394235, 3087839, 2996168, 3022945, 40156505, 33287040, 33283144, 40150549, 40150746, 3026863, 11700, 11554 ) Let me throw in the delegate method implemented also: - (void)UploadDecisionViewController:(UploadDecisionViewController *)controller madeChoice:(NSString *)whichDirection { NSLog(@"it got to here 245"); [self dismissModalViewControllerAnimated:YES]; if (yesOrNo) { //open up the FileUploadViewController and proceed to upload [self performSelector:@selector(showFUModalView) withObject:nil afterDelay:0.5]; } } Can someone tell me what the heck is going on? Thanks a bunch for the help...

• Programmatically configure MATLAB

  - by Richie Cotton

  Since MathWorks release a new version of MATLAB every six months, it's a bit of hassle having to set up the latest version each time. What I'd like is an automatic way of configuring MATLAB, to save wasting time on administrative hassle. The sorts of things I usually do when I get a new version are: Add commonly used directories to the path. Create some toolbar shortcuts. Change some GUI preferences. The first task is easy to accomplish programmatically with addpath and savepath. The next two are not so simple. Details of shortcuts are stored in the file 'shortcuts.xml' in the folder given by prefdir. My best idea so far is to use one of the XML toolboxes in the MATLAB Central File Exchange to read in this file, add some shortcut details and write them back to file. This seems like quite a lot of effort, and that usually means I've missed an existing utility function. Is there an easier way of (programmatically) adding shortcuts? Changing the GUI preferences seems even trickier. preferences just opens the GUI preference editor (equivalent to File - Preferences); setpref doesn't seems to cover GUI options. The GUI preferences are stored in matlab.prf (again in prefdir); this time in traditional name=value config style. I could try overwriting values in this directly, but it isn't always clear what each line does, or how much the names differ between releases, or how broken MATLAB will be if this file contains dodgy values. I realise that this is a long shot, but are the contents of matlab.prf documented anywhere? Or is there a better way of configuring the GUI? For extra credit, how do you set up your copy of MATLAB? Are there any other tweaks I've missed, that it is possible to alter via a script?

• How do I get Spotlight attributes to display in the get info window?

  - by Alexander Rauchfuss

  I have created a spotlight importer for comic files. The attributes are successfully imported and searchable. The one thing that remains is getting the attributes to display in a file's get info window. It seems that this should be a simple matter of editing the schema.xml file so the attributes are nested inside displayattrs tags. Unfortunately this does not seem to be working. I simplified the plugin for testing. The following are all of the important files. schema.xml <types> <type name="cx.c3.cbz-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> <type name="cx.c3.cbr-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> GetMetadataForFile.m Boolean GetMetadataForFile(void* thisInterface, CFMutableDictionaryRef attributes, CFStringRef contentTypeUTI, CFStringRef pathToFile) { NSAutoreleasePool * pool = [NSAutoreleasePool new]; NSString * file = (NSString *)pathToFile; NSArray * authors = [[UKXattrMetadataStore stringForKey: @"com_opencomics_authors" atPath: file traverseLink: NO] componentsSeparatedByString: @","]; [(NSMutableDictionary *)attributes setObject: authors forKey: (id)kMDItemAuthors]; NSString * title = [UKXattrMetadataStore stringForKey: @"com_opencomics_title" atPath: file traverseLink: NO]; [(NSMutableDictionary *)attributes setObject: title forKey: (id)kMDItemTitle]; [pool release]; return true; }

• What can a company possibly gain by making Android phones hard to root?

  - by Chinmay Kanchi

  As someone who recently got a HTC Hero, I had to jump through several hoops to get root access on the phone to install custom firmware. Now, Android is open-source and fairly easy to build and hack on an emulator. It seems to be against the spirit of open-source to lock down a phone so you can't hack the phone itself. Now, often, there are understandable (though not always justifiable) reasons for locking a device down. For example, it might have proprietary software on it or you might want to retain control of the platform. However, Android by its open-source nature makes such concerns moot. Everyone and their dog has access to the userland code, and HTC is forced by the GPL to release kernel sources for each of their devices. So, I fail to see any motivation for alienating the hackers, when there is no possible benefit (in my mind) to be had from doing this. Any idea why a company would want to do this? Is it just short-sightedness or am I missing possible commercial implications of this?

• Need help with version number schemes

  - by Davy8

  I know the standard Major.Minor.Build.Revision but there's several considerations for us that are somewhat unique -We do internal releases almost daily, occasionally more than once a day. -Windows Installer doesn't check Revision so that's almost moot for our purposes. -Major and Minor numbers ideally are only updated for public releases and should be done manually. -That leaves the Build # that needs to be automatically updated. -We want internal releases to be able to be performed from any developer's machine so that leaves out using x.x.* in Visual Studio because different numbers could be generated from different machines and each build isn't guaranteed to be larger than the previous. -We have about 15 or so projects as part of the product so saving the version numbers in SVN isn't ideal since every release we'd have commit all those files. Given those criteria I can't really come up with a good versioning scheme. The last 2 criteria could be dropped but meeting all of those seems ideal. A date stamp is insufficient because we might do more than one a day, and given the max size of Uint32 (around 64000) (Actually using WiX it complains about numbers higher than Int32.MaxValue) a date/time won't fit.

• Displaying modal view in Objective-C

  - by kpower

  I'm trying to display Modal View in my app. I have subclass of UIViewController that has only the "Done" button (UIButton created with IB and linked with XCode). .h @interface myModalVC : UIViewController { UIButton *bDone; } @property (nonatomic, retain) IBOutlet UIButton *bDone; - (IBAction)bDoneTouchDown:(id)sender; @end .m #import "myModalVC.h" @implementation myModalVC @synthesize bDone; - (void)dealloc { [bDone release]; [super dealloc]; } - (void)viewDidLoad { [super viewDidLoad]; } - (void)viewDidUnload { } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (UIInterfaceOrientationLandscapeLeft == interfaceOrientation || UIInterfaceOrientationLandscapeRight == interfaceOrientation); } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (IBAction)bDoneTouchDown:(id)sender { [self.parentViewController dismissModalViewControllerAnimated:YES]; } @end I'm trying to display modal view with this code (from my main view): myModalVC *temp = [[[myModalVC alloc] initWithNibName:@"myModalVC" bundle:[NSBundle mainBundle]] autorelease]; [self presentModalViewController:temp animated:YES]; If this code is placed in some method, that responds to button touches - everything is fine. But when I place it to some other method (called during some processes in my app) - modal view is displayed without problems, but when I press (touch) "Done" button, application crashes with "Program received signal: “EXC_BAD_ACCESS”." What am I doing wrong?
