  • iphone app rejection question

    - by adam d.
    My iPhone app was rejected with the following note: "The following non-public APIs are included in your application: Spi Symbols __memset_chk __memmove_chk" These symbols appear in a small number of apparently cocos2d related object files: Grid.o Primitives.o TextureAtlas.o Curiously, this app had already been approved under the previous SDK, but under 3.2 it's being rejected, though that may have nothing to do with it. I'm not at all sure how to resolve this and appreciate any help anyone can offer. Thanks.

    - by user288245
    I have a bunch of types (eg. LargePlane, SmallPlane) that could be in this collection i've made, how do i print like LargePlane? I've tried like typeOf() and stuff but it doesn't work. Within like a toString()? So when i output the collection it states what type it is.

  • Why can't I reserve 1,000,000,000 in my vector ?

    - by vipersnake005
    When I type in the foll. code, I get the output as 1073741823. #include <iostream> #include <vector> using namespace std; int main() { vector <int> v; cout<<v.max_size(); return 0; } However when I try to resize the vector to 1,000,000,000, by v.resize(1000000000); the program stops executing. How can I enable the program to allocate the required memory, when it seems that it should be able to? I am using MinGW in Windows 7. I have 2 GB RAM. Should it not be possible? In case it is not possible, can't I declare it as an array of integers and get away? BUt even that doesn't work. Another thing is that, suppose I would use a file(which can easily handle so much data ). How can I let it read and write and the same time. Using fstream file("file.txt', ios::out | ios::in ); doesn't create a file, in the first place. But supposing the file exists, I am unable to use to do reading and writing simultaneously. WHat I mean is this : Let the contents of the file be 111111 Then if I run : - #include <fstream> #include <iostream> using namespace std; int main() { fstream file("file.txt",ios:in|ios::out); char x; while( file>>x) { file<<'0'; } return 0; } Shouldn't the file's contents now be 101010 ? Read one character and then overwrite the next one with 0 ? Or incase the entire contents were read at once into some buffer, should there not be atleast one 0 in the file ? 1111110 ? But the contents remain unaltered. Please explain. Thank you.

  • C++ beginner question regarding chars

    - by Samwhoo
    I'm just messing around with some C++ at the moment trying to make a simple tic-tac-toe game and I'm running into a bit of a problem. This is my code: #include <iostream> using namespace std; class Square { public: char getState() const; void setState(char); Square(); ~Square(); private: char * pState; }; class Board { public: Board(); ~Board(); void printBoard() const; Square getSquare(short x, short y) const; private: Square board[3][3]; }; int main() { Board board; board.getSquare(1,2).setState('1'); board.printBoard(); return 0; } Square::Square() { pState = new char; *pState = ' '; } Square::~Square() { delete pState; } char Square::getState() const { return *pState; } void Square::setState(char set) { *pState = set; } Board::~Board() { } Board::Board() { } void Board::printBoard() const { for (int x = 0; x < 3; x++) { cout << "|"; for (int y = 0; y < 3; y++) { cout << board[x][y].getState(); } cout << "|" << endl; } } Square Board::getSquare(short x, short y) const { return board[x][y]; } Forgive me if there are blatantly obvious problems with it or it's stupidly written, this is my first program in C++ :p However, the problem is that when I try and set the square 1,2 to the char '1', it doesn't print out as a 1, it prints out as some strange character I didn't recognise. Can anyone tell me why? :) Thanks in advance.

  • plain old system.out question

    - by mac
    I was looking at someone's code and saw that he repeatedly declared PrintStream out = System.out; and later called out.println("blah"); I actually thought this was kind of neat. Is this a common practice? Was he just being fancy?

  • Question about inserting/updating rows with MS SQL (ASP.NET MVC)

    - by Alex
    I have a very big table with a lot of rows, every row has stats for every user for certain days. And obviously I don't have any stats for future. So to update the stats I use UPDATE Stats SET Visits=@val WHERE ... a lot of conditions ... AND Date=@Today But what if the row doesn't exist? I'd have to use INSERT INTO Stats (...) VALUES (Visits=@val, ..., Date=@Today) How can I check if the row exists or not? Is there any way different from doing the COUNT(*)? If I fill the table with empty cells, it'd take hundreds of thousands of rows taking megabytes and storing no data.

  • Sqlite3 INSERT INTO Question × 377

    - by user316717
    Hi, My 1st post. I am creating an exercise app that will record the weight used and the number of "reps" the user did in 4 "Sets" per day over a period of 7 days so the user may view their progress. I have built the database table named FIELDS with 2 columns ROW and FIELD_DATA and I can use the code below to load the data into the db. But the code has a sql statement that says, INSERT OR REPLACE INTO FIELDS (ROW, FIELD_DATA)VALUES (%d, '%@'); When I change the statment to: INSERT INTO FIELDS (ROW, FIELD_DATA)VALUES (%d, '%@'); Nothing happens. That is no data is recorded in the db. Below is the code: #define kFilname @"StData.sqlite3" - (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kFilname]; } -(IBAction)saveData:(id)sender; { for (int i = 1; i <= 8; i++) { NSString *fieldName = [[NSString alloc]initWithFormat:@"field%d", i]; UITextField *field = [self valueForKey:fieldName]; [fieldName release]; NSString *insert = [[NSString alloc] initWithFormat: @"INSERT OR REPLACE INTO FIELDS (ROW, FIELD_DATA) VALUES (%d, '%@');",i, field.text]; // sqlite3_stmt *stmt; char *errorMsg; if (sqlite3_exec (database, [insert UTF8String], NULL, NULL, &errorMsg) != SQLITE_OK) { // NSAssert1(0, @"Error updating table: %s", errorMsg); sqlite3_free(errorMsg); } } sqlite3_close(database); } So how do I modify the code to do what I want? It seemed like a simple sql statement change at first but obviously there must be more. I am new to Objective-C and iPhone programming. I am not new to using sql statements as I have been creating web apps in ASP for a number of years. Any help will be greatly appreciated, this is driving me nuts! Thanks in advance Dave

  • Question about r-value in C++0x

    - by Goofy
    Rvalues IMHO are great improvement in C++, but at the beginning the're seems quite. Please look at code below: #include <string> std::string && foo (void) { std::string message ("Hello!"); return std::move (message); } void bar (const std::string &message2) { if (message == "Bye Bye!") return; } int main () { bar (foo ()); } Reference message2 is last owner of original message object returned by foo(), right?

  • iphone UIPicker question

    - by Rob
    I have a picker that prompts the user to choose a gender and an age group (17-21, 22-26, etc.) These 2 choices determine which view the user will be brought to after pressing the button, but I am having troubles writing the method for that button. The code I have so far is this: - (IBAction) buttonPressed { NSInteger genderRow = [genderPicker selectedRowInComponent:0]; NSString *genderSelected = [genderPickerData objectAtIndex:genderRow]; NSInteger ageRow = [agePicker selectedRowInComponent:1]; NSString *ageSelected = [agePickerData objectAtIndex:ageRow]; if (genderSelected == "Male" && ageSelected == "17-21") { Calc2ViewController *calc2ViewController = [[Calc2ViewController alloc] initWithNibName:@"Calc2View" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:calc2ViewController animated:YES]; [calc2ViewController release]; calc2ViewController = nil; } } When I run the program, and select these 2 groups (Male and 17-21) - nothing happens. What am I missing?

  • Same memory space being allocated again & again while using malloc()

    - by shadyabhi
    In each loop iteration, variable j is declared again and again. Then why is its address remaining same? Shouldn't it be given some random address each time? Is this compiler dependent? #include<stdio.h> #include<malloc.h> int main() { int i=3; while (i--) { int j; printf("%p\n", &j); } return 0; } Testrun:- shadyabhi@shadyabhi-desktop:~/c$ gcc test.c shadyabhi@shadyabhi-desktop:~/c$ ./a.out 0x7fffc0b8e138 0x7fffc0b8e138 0x7fffc0b8e138 shadyabhi@shadyabhi-desktop:~/c$

  • MySQL Join a Table if Exists Question

    - by swhitlow
    I have a DB which has a table called "config". This table could possibly have a "config_cstm" table that is related by the id to the config table. I was wondering - is there a way to dynamically check for the existence of this table in one simple select statement? In other words, something like: "select * from config (IF EXISTS config_cstm THEN LEFT OUTER JOIN config_cstm ON config.id = config_cstm.id_c" I know how I would go about checking for the existence of an existing table in PHP. I was wanting to do this all in one MySQL statement though. Any suggestions? Thanks!

    I am attempting to put all my database connections in 1 php file, rather than in each of my individual php pages.
