  • Is there a way to visualize records stored in an iPhone app via Core Data?

    - by Justin Searls
    I have an app which, for good reasons, can only be debugged on a device. I'm using Core Data for the first time, and I'd like to be able to easily inspect the records that are stored by the app on the device. I imagine that Core Data is by default backed by SQLite on the iPhone, so this question might be as simple as asking: "What's the easiest way to extract the SQLite database for an app installed by Xcode without jailbreaking it?" Any experience someone could lend regarding this would be greatly appreciated.

  • Project in Eclipse contains only a .project file

    - by demenzia
    I have several projects in Perforce that I need to maintain in Eclipse. I did a successful import the first time, but I've since removed all projects from the workspace and deleted the Perforce files from the P4 folder. I'm not very familiar with Perforce so I'm not sure why whenever I try to re-import those projects, all I get is a .project file instead of the whole package. Any help would be appreciated. Thanks.

  • Linked List manipulation, issues retrieving data c++

    - by floatfil
    I'm trying to implement some functions to manipulate a linked list. The implementation is a template typename T and the class is 'List' which includes a 'head' pointer and also a struct: struct Node { // the node in a linked list T* data; // pointer to actual data, operations in T Node* next; // pointer to a Node }; Since it is a template, and 'T' can be any data, how do I go about checking the data of a list to see if it matches the data input into the function? The function is called 'retrieve' and takes two parameters, the data and a pointer: bool retrieve(T target, T*& ptr); // This is the prototype we need to use for the project "bool retrieve : similar to remove, but not removed from list. If there are duplicates in the list, the first one encountered is retrieved. Second parameter is unreliable if return value is false. E.g., " Employee target("duck", "donald"); success = company1.retrieve(target, oneEmployee); if (success) { cout << "Found in list: " << *oneEmployee << endl; } And the function is called like this: company4.retrieve(emp3, oneEmployee) So that when you cout *oneEmployee, you'll get the data of that pointer (in this case the data is of type Employee). (Also, this is assuming all data types have the apropriate overloaded operators) I hope this makes sense so far, but my issue is in comparing the data in the parameter and the data while going through the list. (The data types that we use all include overloads for equality operators, so oneData == twoData is valid) This is what I have so far: template <typename T> bool List<T>::retrieve(T target , T*& ptr) { List<T>::Node* dummyPtr = head; // point dummy pointer to what the list's head points to for(;;) { if (*dummyPtr->data == target) { // EDIT: it now compiles, but it breaks here and I get an Access Violation error. ptr = dummyPtr->data; // set the parameter pointer to the dummy pointer return true; // return true } else { dummyPtr = dummyPtr->next; // else, move to the next data node } } return false; } Here is the implementation for the Employee class: //-------------------------- constructor ----------------------------------- Employee::Employee(string last, string first, int id, int sal) { idNumber = (id >= 0 && id <= MAXID? id : -1); salary = (sal >= 0 ? sal : -1); lastName = last; firstName = first; } //-------------------------- destructor ------------------------------------ // Needed so that memory for strings is properly deallocated Employee::~Employee() { } //---------------------- copy constructor ----------------------------------- Employee::Employee(const Employee& E) { lastName = E.lastName; firstName = E.firstName; idNumber = E.idNumber; salary = E.salary; } //-------------------------- operator= --------------------------------------- Employee& Employee::operator=(const Employee& E) { if (&E != this) { idNumber = E.idNumber; salary = E.salary; lastName = E.lastName; firstName = E.firstName; } return *this; } //----------------------------- setData ------------------------------------ // set data from file bool Employee::setData(ifstream& inFile) { inFile >> lastName >> firstName >> idNumber >> salary; return idNumber >= 0 && idNumber <= MAXID && salary >= 0; } //------------------------------- < ---------------------------------------- // < defined by value of name bool Employee::operator<(const Employee& E) const { return lastName < E.lastName || (lastName == E.lastName && firstName < E.firstName); } //------------------------------- <= ---------------------------------------- // < defined by value of inamedNumber bool Employee::operator<=(const Employee& E) const { return *this < E || *this == E; } //------------------------------- > ---------------------------------------- // > defined by value of name bool Employee::operator>(const Employee& E) const { return lastName > E.lastName || (lastName == E.lastName && firstName > E.firstName); } //------------------------------- >= ---------------------------------------- // < defined by value of name bool Employee::operator>=(const Employee& E) const { return *this > E || *this == E; } //----------------- operator == (equality) ---------------- // if name of calling and passed object are equal, // return true, otherwise false // bool Employee::operator==(const Employee& E) const { return lastName == E.lastName && firstName == E.firstName; } //----------------- operator != (inequality) ---------------- // return opposite value of operator== bool Employee::operator!=(const Employee& E) const { return !(*this == E); } //------------------------------- << --------------------------------------- // display Employee object ostream& operator<<(ostream& output, const Employee& E) { output << setw(4) << E.idNumber << setw(7) << E.salary << " " << E.lastName << " " << E.firstName << endl; return output; } I will include a check for NULL pointer but I just want to get this working and will test it on a list that includes the data I am checking. Thanks to whoever can help and as usual, this is for a course so I don't expect or want the answer, but any tips as to what might be going wrong will help immensely!

  • stm monad problem

    - by Alex
    This is just a hypothetical scenario to illustrate my question. Suppose that there are two threads and one TVar shared between them. In one thread there is an atomically block that reads the TVar and takes 10s to complete. In another thread is an atomically block that modifies the TVar every second. Will the first atomically block ever complete? Surely it will just keep going back to the beginning, because the log is in an inconsistent state?

  • GCC compile time division error

    - by kartikmohta
    Can someone explain this behaviour? test.c: #include <stdio.h> int main(void) { printf("%d, %d\n", (int) (300.6000/0.05000), (int) (300.65000/0.05000)); printf("%f, %f\n", (300.6000/0.05000), (300.65000/0.05000)); return 0; } $ gcc test.c $ ./a.out 6012, 6012 6012.000000, 6013.000000 I checked the assembly code and it puts both the arguments of the first printf as 6012, so it seems to be a compile time bug.

  • Prevent Apache from chunking gzipped content

    - by Bear
    When using mod_deflate in Apache2, Apache will chunk gzipped content, setting the Transfer-encoding: chunked header. While this results in a faster download time, I cannot display a progress bar. If I handle the compression myself in PHP, I can gzip it completely first and set the Content-length header, so that I can display a progress bar to the user. Is there any way to change Apache's behavior, and have Apache set a Content-length header instead of chunking the response, so that I don't have to handle the compression myself?

  • Language resources in separate APK?

    - by Rudolf
    I'm wondering if it is possible to create a separate APK file which contains only language specific strings and somehow persuade my program to try to read the string resources first from that package's resource and then from the program's own resources... I would like to have a main program with 2-3 mayor laguages and the rest of the languages would go into a separate language pack. (This is to keep the main program size small as I have already 12 translations)

  • How to search a file for a pattern and get a new file from the match point to end of file?

    - by WilliamKF
    I need to take a file and find the first occurrence of a literal string pattern as a complete line of the file: Acknowledgments: And then I wish to create a new file from the line of match all the way to the end of the file. I expect perl is a good way to do this, but I'm not much of a perl person, alternatively maybe sed is a good way? Please suggest a simple way to reliably accomplish this in Unix.

  • How to get "Friends who like/play games" list (similar to Farmville 2)

    - by FBAppDev
    I'm working on a Facebook app, and I'm trying to get a friends list similar to Farmville 2. They have a "friends who like games" list. My first thought is, I can get a list of all friends, then for each friend, see if they like any pages with type == "GAMES/TOYS". But ideally, I would like to get the list in one query (not by making one graph API or FQL request per friend). Is this possible, and if so, how?

  • NServiceBus specify order of Handlers execution

    - by John Simons
    Just wondering if this is the way to specify the order to run a handler (AuthorizationHandler) before all others? public void SpecifyOrder(Order order) { order.Specify(First<AuthorizationHandler>.Then<IHandleMessages<IMessage>>()); } It just feels odd to add Then<IHandleMessages<IMessage>>(). Is there a nicer way of saying to the Bus execute x handler before all others?
