are there code signing certificates cheaper than US $99 per year? [closed]

- by gerryLowry

ksoftware discounts Commodo code signing certificates to US $99 per year. in the past, I've seen Commodo code signing certificates for US $80. I'm excluding CAcert which AFAIK are FREE but are not covered by browsers like IE AFAIK. QUESTION: What is the best price per year for a code signing certificate? Thank you ~~ gerry (lowry) Edit: **THIS SHOULD NOT HAVE BEEN CLOSED** from the FAQ: http://stackoverflow.com/faq ---------------------------- What kind of questions can I ask here?

The dealloc method is not called in the present modal view contrller.

It is in My view controller -(void)doctorsListAction { if(isFirst == YES) { [self getDoctorsListController]; [[self navigationController] presentModalViewController:doctorListViewNavigationController animated:YES]; [doctorListViewController release]; } } -(void)getDoctorsListController { //DoctorListViewController *doctorListViewController=[[[DoctorListViewController alloc]initWithNibName:nil bundle:nil]autorelease]; doctorListViewController=[[DoctorListViewController alloc]init]; doctorListViewNavigationController=[[UINavigationController alloc]initWithRootViewController:doctorListViewController]; doctorListViewController.doctorList=doctorList; doctorListViewNavigationController.navigationBar.barStyle= UIBarStyleBlackOpaque; [doctorListViewController release]; } It is in DoctorListViewContrller -(void)closeAction { printf("\n hai i am in close action*******************************"); //[doctorList release]; //[myTableView release]; //myTableView=nil; printf("\n myTableView retainCount :%d",[myTableView retainCount]); [[self navigationController] dismissModalViewControllerAnimated:YES]; } //this method is not called I don't know why if it not called i will get memory issues - (void)dealloc { printf("\n hai i am in dealloc of Doctor list view contrller"); [doctorList release]; [myTableView release]; myTableView=nil; [super dealloc]; }

iPhone - how to track touches and allow button taps at the same time?

- by Jonathan Cohen

I'm wondering how to track touches anywhere on the iPhone screen and still have UIButtons respond to taps. I subclassed a UIView, made it full screen and the highest view in the hierarchy, and overrode its pointInside:withEvent method. If I return YES, I'm able to track touches anywhere on the screen but the buttons don't respond (likely because the view is instructed to handle and terminate the touch). If I return NO, the touch passes through the view and the buttons respond, but I'm not able to track touches. Do I need to subclass UIButton or is this possible through the responder chain? What am I doing wrong? - (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event{ return NO; } //only works if pointInside:withEvent: returns YES. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"began"); [self.nextResponder touchesBegan:touches withEvent:event]; } //only works if pointInside:withEvent: returns YES. -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ NSLog(@"end"); [self.nextResponder touchesEnded:touches withEvent:event]; }

Script throwing unexpected operator when using mysqldump

- by Astron

A portion of a script I use to backup MySQL databases has stopped working correctly after upgrading a Debian box to 6.0 Squeeze. I have tested the backup code via CLI and it works fine. I believe it is in the selection of the databases before the backup occurs, possibly something to do with the $skipdb variable. If there is a better way to perform the function then I'm will to try something new. Any insight would be greatly appreciated. $ sudo ./script.sh [: 138: information_schema: unexpected operator [: 138: -1: unexpected operator [: 138: mysql: unexpected operator [: 138: -1: unexpected operator Using bash -x script here is one of the iterations: + for db in '$DBS' + skipdb=-1 + '[' test '!=' '' ']' + for i in '$IGGY' + '[' mysql == test ']' + : + '[' -1 == -1 ']' ++ /bin/date +%F + FILE=/backups/hostname.2011-03-20.mysql.mysql.tar.gz + '[' no = yes ']' + /usr/bin/mysqldump --single-transaction -u root -h localhost '-ppassword' mysql + /bin/tar -czvf /backups/hostname.2011-03-20.mysql.mysql.tar.gz mysql.sql mysql.sql + rm -f mysql.sql Here is the code. if [ $MYSQL_UP = "yes" ]; then echo "MySQL DUMP" >> /tmp/update.log echo "--------------------------------" >> /tmp/update.log DBS="$($MYSQL -u $MyUSER -h $MyHOST -p"$MyPASS" -Bse 'show databases')" for db in $DBS do skipdb=-1 if [ "$IGGY" != "" ] ; then for i in $IGGY do [ "$db" == "$i" ] && skipdb=1 || : done fi if [ "$skipdb" == "-1" ] ; then FILE="$DEST$HOST.`$DATE +"%F"`.$db.mysql.tar.gz" if [ $ENCRYPT = "yes" ]; then $MYSQLDUMP -u $MyUSER -h $MyHOST -p"$MyPASS" $db > $db.sql && $TAR -czvf - $db.sql | $OPENSSL enc -aes-256-cbc -salt -out $FILE.enc -k $ENC_PASS && rm -f $db.sql else $MYSQLDUMP --single-transaction -u $MyUSER -h $MyHOST -p"$MyPASS" $db > $db.sql && $TAR -czvf $FILE $db.sql && rm -f $db.sql fi fi done fi

tabBarController and navigationControllers in landscape mode, episode II

- by unforgiven

I have a UITabBarController, and each tab handles a different UIViewController that pushes on the stack new controllers as needed. In two of these tabs I need, when a specific controller is reached, the ability to rotate the iPhone and visualize a view in landscape mode. After struggling a lot I have found that it is mandatory subclassing UITabBarController to override shouldAutorotateToInterfaceOrientation. However, if i simply return YES in the implementation, the following undesirable side effect arises: every controller in every tab is automatically put in landscape mode when rotating the iPhone. Even overriding shouldAutorotateToInterfaceOrientation in each controller to return NO does not work: when the iPhone is rotated, the controller is put in landscape mode. I implemented shouldAutorotateToInterfaceOrientation as follows in the subclassed UITabBarController: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if([self selectedIndex] == 0 || [self selectedIndex] == 3) return YES; return NO; } So that only the two tabs I am interested in actually get support for landscape mode. Is there a way to support landscape mode for a specific controller on the stack of a particular tab? I tried, without success, something like (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if([self selectedIndex] == 0 || [self selectedIndex] == 3) { if ([[self selectedViewController] isKindOfClass: [landscapeModeViewController class]]) return YES; } return NO; } Also, I tried using the delegate method didSelectViewController, without success. Any help is greatly appreciated. Thank you.

HTML checkbox field is being passed to PHP as checked even when it is not

- by Ryan

Hello all, First of all thanks in advance, this has been very frustrating and I'm hoping someone can see something I'm not, I am definitely no php expert. Well here' what is going on. I have a form where I have a checkbox for people to opt in to our newletter. The form element looks like this: <label for=newsletter accesskey=N class="checkbox">Signup for Cloverton's Newsletter</label> <input name="newsletter" type="checkbox" id="newsletter" value="Yes" style="width:20px;" /> That is then submitted to a php file with this code: if (isset($_POST['newsletter']) && $_POST['newsletter'] == 'Yes'){ echo "newletter yes"; $newsletter = 1; }else{ echo "newsletter no"; $newsletter = 0; } $newsletter is then inserted into a database field. The issue is that whether the box is checked or not it is being sent to php as true, so every entry is receiving the newsletter. Any help would be greatly appreciated! Thanks!

Adding shortcut for WiX file in a different fragment.

- by matt

I'm using heat.exe to generate fragments similar to this: <Fragment> <DirectoryRef Id="INSTALLDIR"> <Component Id="id1" Guid="*"> <File Id="fid1" KeyPath="yes" Source="SourceDir\Foo1.dll" /> </Component> <Component Id="id2" Guid="*"> <File Id="fid2" KeyPath="yes" Source="SourceDir\Foo2.dll" /> </Component> <Component Id="id3" Guid="*"> <File Id="fid3" KeyPath="yes" Source="SourceDir\Bar.exe" /> </Component> </DirectoryRef> </Fragment> <Fragment> <ComponentGroup Id="Components"> <ComponentRef Id="id1" /> <ComponentRef Id="id2" /> <ComponentRef Id="id3" /> </ComponentGroup> </Fragment> These fragments are stored in the auto-generated wxs file. I'm then adding them into my feature (in the main WiX file) like so: <ComponentGroupRef Id="Components"/> This works fine. However, I'd also like to add a shortcut to Bar.exe to my start menu. I ideally want to do this in my main wix file, with the Bar.exe component still residing in the auto-generated wxs file. How would I approach this problem without modifying the auto-generated code?

Implementation of "Automatic Lightweight Migration" for Core Data (iPhone)

- by RickiG

Hi I would like to make my app able to do an automatic lightweight migration when I add new attributes to my core data model. In the guide from Apple this is the only info on the subject I could find: Automatic Lightweight Migration To request automatic lightweight migration, you set appropriate flags in the options dictionary you pass in addPersistentStoreWithType:configuration:URL:options:error:. You need to set values corresponding to both the NSMigratePersistentStoresAutomaticallyOption and the NSInferMappingModelAutomaticallyOption keys to YES: NSError *error; NSURL *storeURL = <#The URL of a persistent store#>; NSPersistentStoreCoordinator *psc = <#The coordinator#>; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; if (![psc addPersistentStoreWithType:<#Store type#> configuration:<#Configuration or nil#> URL:storeURL options:options error:&error]) { // Handle the error. } My NSPersistentStoreCoordinator is initialized in this way: - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (persistentStoreCoordinator != nil) { return persistentStoreCoordinator; } NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"FC.sqlite"]]; NSError *error = nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:nil error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } return persistentStoreCoordinator; } I am having trouble seeing where and how I should add the Apple code to get the Automatic Lightweight Migration working?

iPhone slide view passing variables

- by sebastyuiop

Right, I'm trying to make an app that has a calculation that involves a stopwatch. When a button on the calculation view is clicked a stopwatch slides in from the bottom. This all works fine, the problem I can't get my head around is how to send the recorded time back to the previous controller to update a textfield. I've simplified the code and stripped out most irrelevant stuff. Many thanks. CalculationViewController.h #import <UIKit/UIKit.h> @interface CalculationViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITextField *inputTxt; } @property (nonatomic, retain) UITextField *inputTxt; - (IBAction)showTimer:(id)sender; @end CalculationViewController.m #import "CalculationViewController.h" #import "TimerViewController.h" @implementation CalculationViewController - (IBAction)showTimer:(id)sender { TimerViewController *timerView = [[TimerViewController alloc] init]; [self.navigationController presentModalViewController:timerView animated:YES]; } TimerViewController.h #import <UIKit/UIKit.h> @interface TimerViewController : UIViewController { IBOutlet UILabel *time; NSTimer *myTicker; } - (IBAction)start; - (IBAction)stop; - (IBAction)reset; - (void)showActivity; @end TimerViewController.m #import "TimerViewController.h" #import "CalculationViewController.h" @implementation TimerViewController - (IBAction)start { myTicker = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(showActivity) userInfo:nil repeats:YES]; } - (IBAction)stop { [myTicker invalidate]; #Update inputTxt on calculation view here [self dismissModalViewControllerAnimated:YES]; } - (IBAction)reset { time.text = @"0"; } - (void)showActivity { int currentTime = [time.text intValue]; int newTime = currentTime + 1; time.text = [NSString stringWithFormat:@"%d", newTime]; } @end

PHP, MySQL: mysql substitute for php in_array function

- by Devner

Hi all, Say if I have an array and I want to check if an element is a part of that array, I can go ahead and use in_array( needle, haystack ) to determine the results. I am trying to see the PHP equivalent of this for my purpose. Now you might have an instant answer for me and you might be tempted to say "Use IN". Yes, I can use IN, but that's not fetching the desired results. Let me explain with an example: I have a column called "pets" in DB table. For a record, it has a value: Cat, dog, Camel (Yes, the column data is a comma separated value). Consider that this row has an id of 1. Now I have a form where I can enter the value in the form input and use that value check against the value in the DB. So say I enter the following comma separated value in the form input: CAT, camel (yes, CAT is uppercase & intentional as some users tend to enter it that way). Now when I enter the above info in the form input and submit, I can collect the POST'ed info and use the following query: $search = $_POST['pets']; $sql = "SELECT id FROM table WHERE pets IN ('$search') "; The above query is not fetching me the row that already exists in the DB (remember the record which has Cat, dog, Camel as the value for the pets column?). I am trying to get the records to act as a superset and the values from the form input as subsets. So in this case I am expecting the id value to show up as the values exist in the column, but this is not happending. Now say if I enter just CAT as the form input and perform the search, it should show me the ID 1 row. Now say if I enter just camel, cAT as the form input and perform the search, it should show me the ID 1 row. How can I achieve the above? Thank you.

ASP.NET application - Error when trying to connect to a SQL Server 2008 instance

- by Pablo Dami

Hi everyone! Despite that I’m a regular reader of this great forum, this is my first post on it. I believe that this community can help me with the following problem that I have. I’m trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can’t connect with SQL Server (actually is the same but with several modifications). I’ll enumarate some information related to the problem: S.O: Windows 2003 Server SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes. ASP.NET version: 2.0.50727 The connections via TCP/IP are enabled to the SQL Server instance? Yes. The corresponding user that I have in the connection string, actually exists into the database with the “owner” role? Yes. ORM Tool used: nHibernate I get the following error when I try to run the aplication into the browser: Error while establishing a connection to the server. When connecting to SQL Server 2005, this failure may occur because the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server) In order to isolate the problem, I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can’t. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance. I also google it my problem but sadly I can't find nothing usefull to solve it. If someone can help me I’ll appreciate that. Thank you so much for your time!

Problem pushing multiple view controllers onto navigation controller stack

- by Jim

Hi, I am trying to push three view controllers onto the navigation controller. [self.navigationController pushViewController:one animated:YES]; [self.navigationController pushViewController:two animated:YES]; [self.navigationController pushViewController:three animated:YES]; The desired behavior is that view three will show, and when the back button is pressed it will go to view two and then to view one... What actually happens is that view one is visible and pressing back goes to view two and then back again it goes to view one. Which is to say that view one is shown instead of view three. Very strangely, looking at the viewController array of the navigationController after the calls above show the right entries, and looking at the visibleViewController property shows that it has view three in it... even though view one is visible. If i navigate to a sub view from the visible view one (that shows in the place of view three) and press back from that sub view... it goes to view three. It looks like it is showing view one, but knows it is on view three... I am completely confused... any ideas? Jim

How to use multifieldquery and filters in Lucene.net

- by Khotu Nam

I want to perform a multi field search on a lucene.net index but filter the results based on one of the fields. Here's what I'm currently doing: To index the fields the definitions are: doc.Add(new Field("id", id.ToString(), Field.Store.YES, Field.Index.UN_TOKENIZED)); doc.Add(new Field("title", title, Field.Store.NO, Field.Index.TOKENIZED)); doc.Add(new Field("summary", summary, Field.Store.NO, Field.Index.TOKENIZED, Field.TermVector.YES)); doc.Add(new Field("description", description, Field.Store.NO, Field.Index.TOKENIZED, Field.TermVector.YES)); doc.Add(new Field("distribution", distribution, Field.Store.NO, Field.Index.UN_TOKENIZED)); When I perform the search I do the following: MultiFieldQueryParser parser = new MultiFieldQueryParser(new string[]{"title", "summary", "description"}, analyzer); parser.SetDefaultOperator(QueryParser.Operator.AND); Query query = parser.Parse(text); BooleanQuery bq = new BooleanQuery(); TermQuery tq = new TermQuery(new Term("distribution", distribution)); bq.Add(tq, BooleanClause.Occur.MUST); Filter filter = new QueryFilter(bq); Hits hits = searcher.Search(query, filter); However, the result is always 0 hits. What am I doing wrong?

Passing data back from detailViewController to Uitableview

- by jsetting32

I am currently at the issue where I have a UITableviewCell that needs to be updated. When the user presses on the uitableviewcell - THERES ONLY 1!!, the user is pushed to a UITABLEVIEWCONTROLLER where the user is allowed to select 1 of multiple cells with their own titles. I need to get the clicked tableviewcells title and pass the value back to the parentviewcontroller and update the 1 tableviewcell's name to the one the user clicked in the pushed uitableivewcontroller. Here is a picture of the parent viewcontroller... And heres the picture of the pushed viewcontroller.... I was told earlier yesterday that delegation would be needed but I am unsure what to do at this point :/. Heres some code I use in the parent viewcontroller... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:YES]; ProblemTypes *view = [[ProblemTypes alloc] init]; [self.navigationController pushViewController:view animated:YES]; } I am also NOT USING storyboards, just a few xibs. Also heres the code for the pushedviewcontroller to pop to the parent viewcontroller when a cell is selected... #pragma mark - Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; NSLog(@"Cell's text: %@",cell.textLabel.text); [self.navigationController popViewControllerAnimated:YES]; } Thank you guys!

NSMutableArray Problem - iPhone

- by David Schiefer

Hi, I'm trying to get a UITableView to read it's data from a file. I've attempted it like this: NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory]; self.dataForTable = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName]; This compiles fine, but when saving something to the file in the following snippet, the file is not saved nor anything is written to the array: NSMutableDictionary*userDictionary; userDictionary = [[NSMutableDictionary alloc] init]; [userDictionary setObject:name.text forKey:@"name"]; [userDictionary setObject:email.text forKey:@"email"]; [userDictionary setObject:serial.text forKey:@"serial"]; [userDictionary setObject:notes.text forKey:@"notes"]; [userDictionary setObject:[NSNumber numberWithInt:[licenseType selectedRowInComponent:0]] forKey:@"license_type"]; [userDictionary setObject:[date date] forKey:@"date"]; [userDictionary setObject:[NSNumber numberWithBool:[paymentSwitch isOn]] forKey:@"payment"]; NSString*dirToSaveTo = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSString*fileName = [NSString stringWithFormat:@"%@.plist",name.text]; NSString*saveName = [dirToSaveTo stringByAppendingPathComponent:fileName]; [userDictionary writeToFile:saveName atomically:NO]; NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory]; [self.dataForTable addObject:name.text]; NSLog(@"%@",self.dataForTable); [self.dataForTable writeToFile:fullFileName atomically:YES]; The NSLog just returns (null). The *plist file is never written. What am I doing wrong?

User preferences using SQL and JavaScript

- by Shyam

Hi, I am using Server Side JavaScript - yes, I am actually using Server Side JavaScript. To complexify things even more, I use Oracle as a backend database (10g). With some crazy XSLT and mutant-like HTML generation, I can build really fancy web forms - yes, I am aware of Rails and other likewise frameworks and I choose the path of horror instead. I have no JQuery or other fancy framework at my disposal, just plain ol' JavaScript that should be supported by the underlying engine called Mozilla Rhino. Yes, it is insane and I love it. So, I have a bunch of tables at my disposal and some of them are filled with associative keys that link to values. As I am a people pleaser, I want to add some nifty user-preference driven solutions. My users have all an unique user_id and this user_id is available during the entire session. My initial idea is to have a user preference table, where I have "three" columns: user_id, feature and pref_string. Using a delimiter, such as : or - (haven't thought about a suitable one yet), I could like store a bunch of preferences as a list and store its elements inside an array using the .split-method (similar like the PHP-explode function). The feature column could be like the table name or some identifier for the "feature" i want to link preferences too. I hate hardcoding objects, especially as I want to be able to back these up and reuse this functionality application-wide. Of course I would love better ideas, just keep in mind I cannot just add a library that easily. These preferences could be like "joined" to the table, so I can query it and use its values. I hope it doesn't sounds too complex, because well.. its basically something really simple I need. Thanks!

Django Querysets -- need a less expensive way to do this..

- by rh0dium

Hi all, I have a problem with some code and I believe it is because of the expense of the queryset. I am looking for a much less expensive (in terms of time) way to to this.. log.info("Getting Users") employees = Employee.objects.filter(is_active = True) log.info("Have Users") if opt.supervisor: if opt.hierarchical: people = getSubs(employees, " ".join(args)) else: people = employees.filter(supervisor__name__icontains = " ".join(args)) else: log.info("Filtering Users") people = employees.filter(name__icontains = " ".join(args)) | \ employees.filter(unix_accounts__username__icontains = " ".join(args)) log.info("Filtered Users") log.info("Processing data") np = [] for person in people: unix, p4, bugz = "No", "No", "No" if len(person.unix_accounts.all()): unix = "Yes" if len(person.perforce_accounts.all()): p4 = "Yes" if len(person.bugzilla_accounts.all()): bugz = "Yes" if person.cell_phone != "": exphone = fixphone(person.cell_phone) elif person.other_phone != "": exphone = fixphone(person.other_phone) else: exphone = "" np.append({ 'name':person.name, 'office_phone': fixphone(person.office_phone), 'position': person.position, 'location': person.location.description, 'email': person.email, 'functional_area': person.functional_area.name, 'department': person.department.name, 'supervisor': person.supervisor.name, 'unix': unix, 'perforce': p4, 'bugzilla':bugz, 'cell_phone': fixphone(exphone), 'fax': fixphone(person.fax), 'last_update': person.last_update.ctime() }) log.info("Have data") Now this results in a log which looks like this.. 19:00:55 INFO phone phone Getting Users 19:00:57 INFO phone phone Have Users 19:00:57 INFO phone phone Processing data 19:01:30 INFO phone phone Have data As you can see it's taking over 30 seconds to simply iterate over the data. That is way too expensive. Can someone clue me into a more efficient way to do this. I thought that if I did the first filter that would make things easier but seems to have no effect. I'm at a loss on this one. Thanks To be clear this is about 1500 employees -- Not too many!!

UIImagePickerController random behavior

- by pion

I have the following code snippets: @interface PinRecordNewTableViewController : UITableViewController { } ... @implementation PinRecordNewTableViewController ... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { ... PinRecordNewPicture *pinRecordNewPicture = [[PinRecordNewPicture alloc] initWithNibName:@"PinRecordNewPicture" bundle:nil]; pinRecordNewPicture.delegate = self; [self.navigationController pushViewController:pinRecordNewPicture animated:YES]; [pinRecordNewPicture release]; ... } @interface PinRecordNewPicture : UIViewController ... @implementation PinRecordNewPicture ... - (void)picturePicker:(UIImagePickerControllerSourceType)theSource { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = theSource; picker.allowsEditing = YES; [self presentModalViewController:picker animated:YES]; [picker release]; } - (IBAction) takePicture:(id)sender { UIImagePickerControllerSourceType source = UIImagePickerControllerSourceTypeCamera; if ([UIImagePickerController isSourceTypeAvailable:source]) { [self picturePicker:source]; } It works 80% of the time -- I could get the picture correctly. The problem is that it occasionally failed to take a picture. When tracing the code, I found out that it occasionally goes to -PinRecordNewTableViewController:viewDidUnload. This is where it fails because it set nil to all ivars. What did I do wrong? Did I miss something so it behaves "randomly"? Thanks in advance for your help.

I have this code on javascript side: function changeSelectionStyle(id) { if(document.getElementById(id).className != 'yes'){ document.getElementById(id).className = 'yes'; } else{document.getElementById(id).className = '';} } And this on html: <ul> <li id="selectedAuthorities-4_1li" class=""> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onload="changeSelectionStyle(this.id + 'li');" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle.</samp> </a> </li> Well what I cant get work is when the checkbox is selected, on load, the JS should check it, and assign class="yes" to the li, here: <li id="selectedAuthorities-4_1li" class=""> What should I add to my original JS function to make that possible. Note that li ids are not static, they are dynamic, the html li id is generated.

Object in Array is not recognised as having "methods"

- by kevin Mendoza

I got my application working Awhile back, but after completely and accidentally deleting it, I have tried to create it from square one. unfortunately my rewritten program is a bit cranky; does anyone see or know the possible sources of error? Also, my if statements are acting up. -(void)loadAnnotations { CLLocationCoordinate2D workingCoordinate; iProspectLiteAppDelegate *appDelegate = (iProspectLiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray *mines =[[NSMutableArray alloc] initWithArray:(NSMutableArray *) appDelegate.mines]; BOOL gold = [[NSUserDefaults standardUserDefaults] boolForKey:@"goldControl"]; BOOL silver = [[NSUserDefaults standardUserDefaults] boolForKey:@"silverControl"]; BOOL copper = [[NSUserDefaults standardUserDefaults] boolForKey:@"copperControl"]; for(id mine in mines) { NSLog(@"in the loop"); workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectLiteAnnotation *tempMine = [[iProspectLiteAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTite:[mine mineName]]; if ([[mine commodity] isEqualToString:@"Gold"] && [gold == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeGold]; [mapView addAnnotation:tempMine]; } if([[mine commodity] isEqualToString:@"Silver"] && [silver == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeSilver]; } if([[mine commodity] isEqualToString:@"Copper"] && [copper == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeCopper]; } } [mines dealloc]; } where the workingCoordinate.latitude = [[mine latitudeInitial] doubleValue], as well as the longitude, and [mine mineName],it says " No '-latitudeInitiallongitudeInitial' method found" or the mineName/LongitudeInitial. also, it complains about : before ] at all the if statement lines. I don't see any errors, do you?

how to conditional display a control in asp wizard based on the radiobutton click in a particular st

- by Pramod

Hi, I've been stuck with this problem where there are 3 steps in an asp wizard control. The first step has a radiobutton (yes and no) and based on the radio button input chosen by the user, i would need to hide or show a label in the second wizardstep. Example: Step 1: Choose 1 among the two options: Yes No (radStep1) Step 2: if the radiobutton option in the previous step was yes.. then display a label(lblStep2) in this step.. Else hide the label. I've been handling this through the jquery as i want the functionality in the aspx page itself... The jquery code goes like this... $("#<%=radStep1.ClientID %> input").click(function() { if($("#<%= radStep1.ClientID %> input").index(this) == 0) { $("#<%=lblStep2.ClientID %>").show(); } else if($("#<%= radStep1.ClientID %> input").index(this) == 1) { $("#<%=lblStep2.ClientID %>").hide(); } However, in both the cases, the label is getting displayed.. Could you please help me out if there is anything that i'm missing? I'm guessing that the label is getting hidden at first and then getting shown again once i click on the next button... Thanks a ton in advance....

iPad keyboard will not dismiss if navigation controller presentation style is "form sheet".

- by Kalle

UPDATE: This is apparently "works as intended" classed by Apple. See accepted answer below for details. Update: this question is about a behavior discovered in the iPad keyboard, where it refuses to be dismissed if shown in a modal dialog with a navigation controller. Basically, if I present the navigation controller with the following line: navigationController.modalPresentationStyle = UIModalPresentationFormSheet; The keyboard refuses to be dismissed. If I comment out this line, the keyboard goes away fine. ... I've got two textFields, username and password; username has a Next button and password has a Done button. The keyboard won't go away if I present this in a modal navigation controller. WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; [self.view addSubview:b.view]; DOES NOT WORK broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; navigationController.modalPresentationStyle = UIModalPresentationFormSheet; navigationController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release]; If I remove the navigation controller part and present 'b' as a modal view controller by itself, it works. Is the navigation controller the problem? WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; b.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:b animated:YES]; [b release]; WORKS broken *b = [[broken alloc] initWithNibName:@"broken" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:b]; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; [b release];
