  • NSFetchedResultsController - Delegate methods crashing under iPhone OS 3.0, but NOT UNDER 3.1

    - by Scott Langendyk
    Hey guys, so I've got my NSFetchedResultsController working fine under the 3.1 SDK, however I start getting some weird errors, specifically in the delegate methods when I try it under 3.0. I've determined that this is related to the NSFetchedResultsControllerDelegate methods. This is what I have set up. The inEditingMode stuff has to do with the way I've implemented adding another static section to the table. - (void)controllerWillChangeContent:(NSFetchedResultsController*)controller { [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type{ NSIndexSet *sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex]; if(self.inEditingMode){ sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex + 1]; } switch (type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath{ NSIndexPath *relativeIndexPath = indexPath; NSIndexPath *relativeNewIndexPath = newIndexPath; if(self.inEditingMode){ relativeIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section + 1]; relativeNewIndexPath = [NSIndexPath indexPathForRow:newIndexPath.row inSection:newIndexPath.section + 1]; } switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:relativeNewIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:relativeIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } -(void)controllerDidChangeContent:(NSFetchedResultsController *)controller{ [self.tableView endUpdates]; } When I add an entity to the managed object context, I get the following error: Serious application error. Exception was caught during Core Data change processing: *** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1) with userInfo (null) I put a breakpoint on objc_exception_throw, and the crash seems to be occuring inside of controllerDidChangeContent. If I comment out all of the self.tableView methods, and put a single [self.tableView reloadData] inside of controllerDidChangeContent, everything works as expected. Anybody have any idea as to why this is happening?

  • Storing a set of criteria in another table

    - by bendataclear
    I have a large table with sales data, useful data below: RowID Date Customer Salesperson Product_Type Manufacturer Quantity Value 1 01-06-2004 James Ian Taps Tap Ltd 200 £850 2 02-06-2004 Apple Fran Hats Hats Inc 30 £350 3 04-06-2004 James Lawrence Pencils ABC Ltd 2000 £980 ... Many rows later... ... 185352 03-09-2012 Apple Ian Washers Tap Ltd 600 £80 I need to calculate a large set of targets from table containing values different types, target table is under my control and so far is like: TargetID Year Month Salesperson Target_Type Quantity 1 2012 7 Ian 1 6000 2 2012 8 James 2 2000 3 2012 9 Ian 2 6500 At present I am working out target types using a view of the first table which has a lot of extra columns: SELECT YEAR(Date) , MONTH(Date) , Salesperson , Quantity , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType1 , CASE WHEN Manufacturer = 'Hats Inc' AND Product_Type IN ('Hats','Coats') THEN True ELSE False END AS IsType2 ... ... , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType24 , CASE WHEN Manufacturer IN ('Tap Ltd','Hats Inc') AND Product_Type = 'Hats' THEN True ELSE False END AS IsType25 FROM SalesTable WHERE [some stuff here] This is horrible to read/debug and I hate it!! I've tried a few different ways of simplifying this but have been unable to get it to work. The closest I have come is to have a third table holding the definition of the types with the values for each field and the type number, this can be joined to the tables to give me the full values but I can't work out a way to cope with multiple values for each field. Finally the question: Is there a standard way this can be done or an easier/neater method other than one column for each type of target? I know this is a complex problem so if anything is unclear please let me know. Edit - What I need to get: At the very end of the process I need to have targets displayed with actual sales: Type Year Month Salesperson TargetQty ActualQty 2 2012 8 James 2000 2809 2 2012 9 Ian 6500 6251 Each row of the sales table could potentially satisfy 8 of the types. Some more points: I have 5 different columns that need to be defined against the targets (or set to NULL to include any value) I have between 30 and 40 different types that need to be defined, several of the columns could contain as many as 10 different values For point 2, if I am using a row for each permutation of values, 2 columns with 10 values each would give me 100 rows for each sales person for each month which is a lot but if this is the only way to define multiple values I will have to do this. Sorry if this makes no sense!

  • Writing preprocessor directives to get string

    - by Dave18
    Can you write preprocessor directives to return you a std::string or char*? For example: In case of integers: #define square(x) (x*x) int main() { int x = square(5); } I'm looking to do the same but with strings like a switch-case pattern. if pass 1 it should return "One" and 2 for "Two" so on..

  • Drag and Drop file upload in Silverlight 4?

    - by Parvenu74
    I'm working on re-writing a WinForms application into Silverlight. One use case in the WinForms app allows users to drag TIFF images (of faxes) from Outlook directly onto an "attach an image or fax to this case" control in the WinForms app. Is there a Silverlight 4 control which allows for the same functionality? It's important to realize that saving the file to the local filesystem and then selecting and uploading the file with a standard upload control will not meet the business requirements as outlined in the project.

  • How to save preferences to somewhere other than SharedPreferences

    - by Adrian
    My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences). Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

  • Non RBAC User Roles and Permissions System: a role with properties

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case. This is my second question (the first question is here: http://stackoverflow.com/questions/2839797/non-rbac-user-roles-and-permissions-system-checking-the-users-city). We have the following case: we need to implement a Manager role in our web application. However, a Manager can belong to one or several companies (within a big group of companies for which we are creating this web app). Say, there can be “Manager of companies A and B”, “Manager of company C”, etc. Depending on the companies that the Manager belongs, he has access to certain operations: for example, he can communicate with clients only of those companies that he belongs to. That is, “Manager of companies A and B” can only have contacts with clients of companies A and B, and not with those of company C. He can also view clients’ details pages of companies A and B and not of C, etc. It seems that this case falls within the RBAC. However, this is not really the case. We will need to create a ManagerRole class that will have a Companies property – that is, this will not be just a role as a collection of permissions (like in the classical RBAC), but a role with properties! This was just one example of a role having properties. There will be others: for example, an Administrator role that will also belong to a number of companies and will also have other custom properties. This means that we will a hierarchy or roles classes: class Role – base class class ManagerRole : Role List Companies class AdministratorRole : Role List Companies Other properties We investigated pure RBAC and its implementation in several systems, and found no systems featuring a hierarchy or roles, each having custom properties. In RBAC, roles are just collections of permissions. We could model our cases using permission with properties, like ManagerPermission, AdministratorPermission, but this has a lot of drawbacks, the main being that we will not be able to assign a role like “Manager of Companies A and B” to a user directly, but will have to create a role containing a ManagerPermission for companies A and B… Moreover, a "Manager" seems to be rather a "role" (position in the company) rather than a "permission" from the linguistic point of view. Would be grateful for any ideas on this subject, as well as any experience in this field! Thank you.

  • using REST webservices as a datasource for Lift ?

    - by Jeff Bowman
    Is there a way to use a webservice (REST in this case) as the data source for a Lift application? I can find a number of tutorials/examples of using Lift to provide the REST API, but in my case the data is hosted elsewhere and exported as a REST webservice. Pointers to doc are greatly appreciated. Thanks, Jeff

  • Log call information whenever there is a call.

    - by linuxdoniv
    Hi, I have written the android application and I want the application to send the call information whenever there is an incoming call and it ends. This way I would be sending all calls to the server irrespective of size of the call log. Here is the code public class PhoneInfo extends BroadcastReceiver { private int incoming_call = 0; private Cursor c; Context context; public void onReceive(Context con, Intent intent) { c = con.getContentResolver().query( android.provider.CallLog.Calls.CONTENT_URI, null, null, null, android.provider.CallLog.Calls.DATE+ " DESC");

} public class IncomingCallListener extends PhoneStateListener { public void onCallStateChanged(int state,String incomingNumber){ switch(state){ case TelephonyManager.CALL_STATE_IDLE: if(incoming_call == 1){ CollectSendCallInfo();

  • Deadlock in Java

    - by israkir
    Long time ago, I saved a sentence from a Java reference book: "Java has no mechanism to handle deadlock. it won't even know deadlock occurred." (Head First Java 2nd Edition, p.516) So, what is about it? Is there a way to catch deadlock case in Java? I mean, is there a way that our code understands a deadlock case occurred?

  • iPhone: value of selectedIndex for tab should be consistent, but isn't

    - by Janine
    This should be so simple... but something screwy is happening. My setup looks like this: MainViewController Tab Bar Controller 4 tabs, each of which loads WebViewController My AppDelegate contains an ivar, tabBarController, which is connected to the tab bar controller (this was all set up in Interface Builder). The leftmost tab is marked "selected" in IB. Within the viewWillAppear method in WebViewController, I need to know which tab was just selected so I can load the correct URL. I do this by switching on appDelegate.tabBarController.selectedIndex. When the app first runs and the leftmost tab is selected, selectedIndex is a large garbage value. After that, I get values from 0 to 3, which is as it should be, but they are in random order. Not only that, but each tab I touch reports a different value each time. This app is extremely simple right now and I can't imagine what I could have done to make things go this wrong. Has anyone seen (and hopefully solved) this behavior? Update: we have a request for code. There's not much to see. The tab bar controller gets loaded in applicationDidFinishLaunching: [self.mainViewController view]; //force nib to load [self.window addSubview:self.mainViewController.tabBarController.view] There is currently no code whatsoever in MainViewController.m other than the synthesize and release for tabBarController. From WebVewController.m: - (void)viewWillAppear:(BOOL)_animation { [super viewWillAppear:_animation]; NSURL *url; switch([S_UIDelegate mainViewController].tabBarController.selectedIndex) { case 0: url = [NSURL URLWithString:@"http://www.cnn.com"]; break; case 1: url = [NSURL URLWithString:@"http://www.facebook.com"]; break; case 2: url = [NSURL URLWithString:@"http://www.twitter.com"]; break; case 3: url = [NSURL URLWithString:@"http://www.google.com"]; break; default: url = [NSURL URLWithString:@"http://www.msnbc.com"]; } NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; } This is where I'm seeing the random values.

  • Which HTTP redirect status code is best for this REST API scenario?

    - by Aseem Kishore
    I'm working on a REST API. The key objects ("nouns") are "items", and each item has a unique ID. E.g. to get info on the item with ID foo: GET http://api.example.com/v1/item/foo New items can be created, but the client doesn't get to pick the ID. Instead, the client sends some info that represents that item. So to create a new item: POST http://api.example.com/v1/item/ hello=world&hokey=pokey With that command, the server checks if we already have an item for the info hello=world&hokey=pokey. So there are two cases here. Case 1: the item doesn't exist; it's created. This case is easy. 201 Created Location: http://api.example.com/v1/item/bar Case 2: the item already exists. Here's where I'm struggling... not sure what's the best redirect code to use. 301 Moved Permanently? 302 Found? 303 See Other? 307 Temporary Redirect? Location: http://api.example.com/v1/item/foo I've studied the Wikipedia descriptions and RFC 2616, and none of these seem to be perfect. Here are the specific characteristics I'm looking for in this case: The redirect is permanent, as the ID will never change. So for efficiency, the client can and should make all future requests to the ID endpoint directly. This suggests 301, as the other three are meant to be temporary. The redirect should use GET, even though this request is POST. This suggests 303, as all others are technically supposed to re-use the POST method. In practice, browsers will use GET for 301 and 302, but this is a REST API, not a website meant to be used by regular users in browsers. It should be broadly usable and easy to play with. Specifically, 303 is HTTP/1.1 whereas 301 and 302 are HTTP/1.0. I'm not sure how much of an issue this is. At this point, I'm leaning towards 303 just to be semantically correct (use GET, don't re-POST) and just suck it up on the "temporary" part. But I'm not sure if 302 would be better since in practice it's been the same behavior as 303, but without requiring HTTP/1.1. But if I go down that line, I wonder if 301 is even better for the same reason plus the "permanent" part. Thoughts appreciated!

  • Method/function overrides in Codeigniter

    - by pingu
    Hi guys, I want to override the validation_errors() method of the form helper in CodeIgniter for one controller only, so that it will display a single error message (as a sentence in plain english) instead of the detailed line item summary. I've tried defining a validation_errors() function in my controller, which is what I usually do with Silverstripe's Sapphire framework, but this won't with CI. What's the best way to override methods for a case by case basis?

  • Problems using wxWidgets (wxMSW) within multiple DLL instances

    Preface I'm developing VST-plugins which are DLL-based software modules and loaded by VST-supporting host applications. To open a VST-plugin the host applications loads the VST-DLL and calls an appropriate function of the plugin while providing a native window handle, which the plugin can use to draw it's GUI. I managed to port my original VSTGUI code to the wxWidgets-Framework and now all my plugins run under wxMSW and wxMac but I still have problems under wxMSW to find a correct way to open and close the plugins and I am not sure if this is a wxMSW-only issue. Problem If I use any VST-host application I can open and close multiple instances of one of my VST-plugins without any problems. As soon as I open another of my VST-plugins besides my first VST-plugin and then close all instances of my first VST-plugin the application crashes after a short amount of time within the wxEventHandlerr::ProcessEvent function telling me that the wxTheApp object isn't valid any longer during execution of wxTheApp-FilterEvent (see below). So it seems to be that the wxTheApp objects was deleted after closing all instances of the first plugin and is no longer available for the second plugin. bool wxEvtHandler::ProcessEvent(wxEvent& event) { // allow the application to hook into event processing if ( wxTheApp ) { int rc = wxTheApp->FilterEvent(event); if ( rc != -1 ) { wxASSERT_MSG( rc == 1 || rc == 0, _T("unexpected wxApp::FilterEvent return value") ); return rc != 0; } //else: proceed normally } .... } Preconditions 1.) All my VST-plugins a dynamically linked against the C-Runtime and wxWidgets libraries. With regard to the wxWidgets forum this seemed to be the best way to run multiple instances of the software side by side. 2.) The DllMain of each VST-Plugin is defined as follows: // WXW #include "wx/app.h" #include "wx/defs.h" #include "wx/gdicmn.h" #include "wx/image.h" #ifdef __WXMSW__ #include <windows.h> #include "wx/msw/winundef.h" BOOL APIENTRY DllMain ( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: { wxInitialize(); ::wxInitAllImageHandlers(); break; } case DLL_THREAD_ATTACH: break; case DLL_THREAD_DETACH: break; case DLL_PROCESS_DETACH: wxUninitialize(); break; } return TRUE; } #endif // __WXMSW__ class Application : public wxApp {}; IMPLEMENT_APP_NO_MAIN(Application) Question How can I prevent this behavior respectively how can I properly handle the wxTheApp object if I have multiple instances of different VST-plugins (DLL-modules), which are dynamically linked against the C-Runtime and wxWidgets libraries? Best reagards, Steffen

  • Enum values doubts?

    - by maddy
    Hi all, Is there any possible way to do any arithmetic operations on enum values enum Type{Zero=0,One,Two,Three,Four,Five,Six,Seven,Eight,Nine}; main() { enum Type Var = Zero; for(int i=0;i<10;i++) { switch(Var) { case Zero: /*do something*/ case One: /*Do something*/ ..... } Var++;(I know that this increment is not possible,But is there anyway by which we can have this variable named Var increment. regards maddy

  • Strange iPhone memory leak in xml parser

    - by Chris
    Update: I edited the code, but the problem persists... Hi everyone, this is my first post here - I found this place a great ressource for solving many of my questions. Normally I try my best to fix anything on my own but this time I really have no idea what goes wrong, so I hope someone can help me out. I am building an iPhone app that parses a couple of xml files using TouchXML. I have a class XMLParser, which takes care of downloading and parsing the results. I am getting memory leaks when I parse an xml file more than once with the same instance of XMLParser. Here is one of the parsing snippets (just the relevant part): for(int counter = 0; counter < [item childCount]; counter++) { CXMLNode *child = [item childAtIndex:counter]; if([[child name] isEqualToString:@"PRODUCT"]) { NSMutableDictionary *product = [[NSMutableDictionary alloc] init]; for(int j = 0; j < [child childCount]; j++) { CXMLNode *grandchild = [child childAtIndex:j]; if([[grandchild stringValue] length] > 1) { NSString *trimmedString = [[grandchild stringValue] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; [product setObject:trimmedString forKey:[grandchild name]]; } } // Add product to current category array switch (categoryId) { case 0: [self.mobil addObject: product]; break; case 1: [self.allgemein addObject: product]; break; case 2: [self.besitzeIch addObject: product]; break; case 3: [self.willIch addObject: product]; break; default: break; } [product release]; } } The first time, I parse the xml no leak shows up in instruments, the next time I do so, I got a lot of leaks (NSCFString / NSCFDictionary). Instruments points me to this part inside CXMLNode.m, when I dig into a leaked object: theStringValue = [NSString stringWithUTF8String:(const char *)theXMLString]; if ( _node->type != CXMLTextKind ) xmlFree(theXMLString); } return(theStringValue); I really spent a long time and tried multiple approaches to fix this, but to no avail so far, maybe I am missing something essential? Any help is highly appreciated, thank you!

  • jdbc nested transactions

    - by Nrj
    What is the behaviour of nested transactions. I am using java + jdbc ? Eg: tx1.begin do stuff1 tx2.begin do stuff2 tx2.commit do stuff1.1 tx1.rollback tx2 is basically inside another function. Will the results from tx2 be persisted ? In case behaviour is db specific, what is it in case of Sql server 2005 ?

  • Pythonic / itertools way to go through a dict?

    - by dmd
    def reportCSV(t): ret = '' for ev in t: for p in t[ev]: for w in t[ev][p]: ret += ','.join((ev, p, w, t[ev][p][w])) + '\n' return ret What is a more pythonic way to do this, e.g. using itertools or the like? In this case I'm just writing it out to a CSV file. t is a dict t[ev] is a dict t[ev][p] is a dict t[ev][p][w] is a float I'm not sure how I'd use itertools.product in this case.
