• HTC Incredible displaying blank ImageView

  - by Todd

  HI, I have an app that displays an an image in an ImageView using the setImageDrawable(Drawable) method. However, with the release of the Droid Incredible the images are coming up as a blank screen. I am using Drawable.createFromPath(Environment.getExternalStorageDirectory() + "\imagefile") to access the image from the SD card. I don't get any sort of error, just a black screen. I will get a null pointer exception if after trying to load the image I try to access a property of the Drawable. This makes me believe that the Drawable wasn't loaded, but I don't know why or how to make it work. This code as been working on all other Android devices, so I'm not sure what is different with the Incredible. Unfortunately I don't have access to an Incredible to test on, so I've got to rely on others to test and send me the log files. Any help you can offer would be greatly appreciated. If anyone knows how to replicate this issue on the emulator, that would be helpful too. I've configured an emulator with firmware 7 and the correct screen resolution, but I was unable to replicate the issue. Thanks.

• Is there a way to programatically check dependencies of an EXE?

  - by Mason Wheeler

  I've got a certain project that I build and distribute to users. I have two build configurations, Debug and Release. Debug, obviously, is for my use in debugging, but there's an additional wrinkle: the Debug configuration uses a special debugging memory manager, with a dependency on an external DLL. There's been a few times when I've accidentally built and distributed an installer package with the Debug configuration, and it's then failed to run once installed because the users don't have the special DLL. I'd like to be able to keep that from happening in the future. I know I can get the dependencies in a program by running Dependency Walker, but I'm looking for a way to do it programatically. Specifically, I have a way to run scripts while creating the installer, and I want something I can put in the installer script to check the program and see if it has a dependency on this DLL, and if so, cause the installer-creation process to fail with an error. I know how to create a simple CLI program that would take two filenames as parameters, and could run a DependsOn function and create output based on the result of it, but I don't know what to put in the DependsOn function. Does anyone know how I'd go about writing it?

• Getting error when compiling debug mode: C++/CLI - error LNK2022

  - by Yochai Timmer

  I've got a CLI code wrapping a C++ DLL. When i try to compile it in debug mode, i get the following error: Error 22 error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information induplicated types .... MSVCMRTD.lib (locale0_implib.obj) The weird thing is that on Release mode it compiles OK and works OK. The only difference i can see that causes the problem is when i change: Configuration Properties - C/C++ - Code Generation - Runtime Library When it's set to: Multi-threaded Debug DLL (/MDd) it throws the error. When it's set to: Multi-threaded DLL (/MD) it compiles fine. The same settings work for all the other DLLs in the project (CLI and C++) and they inherit the same properties. I'm using VS2010. So, how can i solve this ? And can I get some explanation to WHY this is happening ? Update: I've basically tried changing every option in the project's properties with no luck. I've read somewhere that this might be caused from duplicate declarations of a type of the same name. But in the CLI file i'm calling std::string etc. explicitly from std. Any other ideas ?

• 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); } }

• [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)">

• 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 :)

• 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.

• 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

• 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?

• Are function-local typedefs visible inside C++0x lambdas?

  - by GMan - Save the Unicorns

  I've run into a strange problem. The following simplified code reproduces the problem in MSVC 2010 Beta 2: template <typename T> struct dummy { static T foo(void) { return T(); } }; int main(void) { typedef dummy<bool> dummy_type; auto x = [](void){ bool b = dummy_type::foo(); }; // auto x = [](void){ bool b = dummy<bool>::foo(); }; // works } The typedef I created locally in the function doesn't seem to be visible in the lambda. If I replace the typedef with the actual type, it works as expected. Here are some other test cases: // crashes the compiler, credit to Tarydon int main(void) { struct dummy {}; auto x = [](void){ dummy d; }; } // works as expected int main(void) { typedef int integer; auto x = [](void){ integer i = 0; }; } I don't have g++ 4.5 available to test it, right now. Is this some strange rule in C++0x, or just a bug in the compiler? From the results above, I'm leaning towards bug. Though the crash is definitely a bug. For now, I have filed two bug reports. All code snippets above should compile. The error has to do with using the scope resolution on locally defined scopes. (Spotted by dvide.) And the crash bug has to do with... who knows. :) Update According to the bug reports, they have both been fixed for the next release of Visual Studio 2010.

• 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.

• 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" }) }

• 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.

• 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.

• 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?

• strange memory error when deleting object from Core Data

  - by llloydxmas

  I have an application that downloads an xml file, parses the file, and creates core data objects while doing so. In the parse code I have a function called 'emptydatacontext' that removes all items from Core Data before creating replacements from the xml file. This method looks like this: -(void) emptyDataContext { NSMutableArray* mutableFetchResults = [CoreDataHelper getObjectsFromContext:@"Condition" :@"road" :NO :managedObjectContext]; NSFetchRequest * allCon = [[NSFetchRequest alloc] init]; [allCon setEntity:[NSEntityDescription entityForName:@"Condition" inManagedObjectContext:managedObjectContext]]; NSError * error = nil; NSArray * conditions = [managedObjectContext executeFetchRequest:allCon error:&error]; [allCon release]; for (NSManagedObject * condition in conditions) { [managedObjectContext deleteObject:condition]; } } The first time this runs it deletes all objects and functions as it should - creating new objects from the xml file. I created a 'update' button that starts the exact same process of retrieving the file the preceeding as it did the first time. All is well until its time to delete the core data objects again. This 'deleteObject' call creates a "EXC_BAD_ACCESS" error each time. This only happens on the second time through. See this image for the debugger window as it appears when walking through the deletion FOR loop on the second iteration. Conditions is the fetched array of 7 objects with the objects below. Condition should be an individual condition. link text As you can see 'condition' does not match any of the objects in the 'conditions' array. I'm sure this is why I'm getting the memory access errors. Just not sure why this fetch (or the FOR) is returning a wrong reference. All the code that successfully performes this function on the first iteration is used in the second but with very different results. Thanks in advance for the help!

• 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.

• strcmp() but with 0-9 AFTER A-Z? (C/C++)

  - by Aaron

  For reasons I completely disagree with but "The Powers (of Anti-Usability) That Be" continue to decree despite my objections, I have a sorting routine which does basic strcmp() compares to sort by its name. It works great; it's hard to get that one wrong. However, at the 11th hour, it's been decided that entries which begin with a number should come AFTER entries which begin with a letter, contrary to the ASCII ordering. They cite the EBCDIC standard has numbers following letters so the prior assumption isn't a universal truth, and I have no power to win this argument... but I digress. Therein lies my problem. I've replaced all appropriate references to strcmp with a new function call nonstd_strcmp, and now need to implement the modifications to accomplish the sort change. I've used a FreeBSD source as my base: http://freebsd.active-venture.com/FreeBSD-srctree/newsrc/libkern/strncmp.c.html if (n == 0) return (0); do { if (*s1 != *s2++) return (*(const unsigned char *)s1 - *(const unsigned char *)(s2 - 1)); if (*s1++ == 0) break; } while (--n != 0); return (0); I guess I might need to take some time away to really think about how it should be done, but I'm sure I'm not the only one who's experienced the brain-deadness of just-before-release spec changes.

• a + sing in email address

  - by d.andreykiv

  Hi. I need to submit an email address with a "+" sign and validate in on server. But server receives email like "[email protected]" as "aaa [email protected]". I send all data as POST request with following code NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@", url, @"/signUp"]]; NSString *post = [NSString stringWithFormat:@"&email=%@&userName=%@&password=%@", user.email, user.userName, user.password]; NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO]; NSData* data = [self sendRequest:url postData:postData]; post variable before encoding has value &[email protected]&userName=Asdfasdfadsfadsf&password=sdfasdf after encoding it is same &[email protected]&userName=Asdfasdfadsfadsf&password=sdfasdf Method I use to send request looks like following code: -(id) sendRequest:(NSURL*) url postData:(NSData*)postData { // Create request NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; [request setURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:postData]; NSURLResponse *urlResponse; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:nil]; [request release]; return data; }

• 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; }

• ApplicationDelegate is not doing its own job here ! Can anyone help me??

  - by ahmet732

  (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MaSystemGuiAppDelegate *appDelegate = (MaSystemGuiAppDelegate *)[[UIApplication sharedApplication] delegate]; appDelegate.deneme = [tableData objectAtIndex:indexPath.row] ; NSLog(@"my row", appDelegate.deneme); // THIS IS NOT PRINTING NSLog(@"my row = %@", [tableData objectAtIndex:indexPath.row]); //THIS IS PRINTING THE VALUE ON CONSOLE NSInteger row = [indexPath row]; if(self.searchDetailViewController == nil){ SearchDetailViewController *asearchDetail = [[SearchDetailViewController alloc] initWithNibName:@"SearchDetailView" bundle:nil]; self.searchDetailViewController = asearchDetail; [asearchDetail release]; } searchDetailViewController.title = [NSString stringWithFormat:@"%@", [searchArray objectAtIndex:row]]; MaSystemGuiAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.searchNavController pushViewController:searchDetailViewController animated:YES]; } "deneme" is a NMUtableArray is identified in MaSystemGuiAppDelegate.h (I identified it as a variable and put its property there) and I wrote "deneme= [[NSMutableArray alloc]init]; in applicationDidFinishLaunching method in MaSystemGuiAppDelegate.m. In the code above, [tableData objectAtIndex:indexPath.row] is retrieving the one of the value touched on tableview. When I put that value in deneme (as u noticed in the code) it is printing nothing. What am i missing? (I imported MaSystemGuiAppDelegate.h)
