  • Delegates does not work properly

    - by Warrior
    I am new to iPhone development. I am converting the date to the desired format and set it to the delegate and get its value in the another view. The session restarts when I tried to get the value from delegate. If I set the original date and not the formatted date in the set delegate, then i able to get the value in the another view. If I also give any static string value, then also I am able to the static string value back. Only the formatted date which is string is set then the session restarts. If i print and check the value of the formatted date it prints the correct formatted date only.Please help me out.Here is my code for date conversion NSString *dateval=[[stories objectAtIndex: storyIndex] objectForKey:@"date"]; NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init]; [inputFormatter setDateFormat:@"EEE, MMM dd, yyyy"]; NSDate *inputDate = [inputFormatter dateFromString:dateval]; NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init]; [outputFormatter setDateFormat:@"MMMM dd"]; NSString *outputDate = [outputFormatter stringFromDate:inputDate]; AppDelegate *delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate]; [delegate setCurrentDates:outputDate]; EDIT: This is displayed in console inside view did load [Session started at 2010-04-21 19:12:53 +0530.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • How to execute a program from file descriptor?

    - by stribika
    I need to execute a file when I only know the descriptor. It is also possible that there are no links to the file so finding out the name somehow is not an option. All the execve(), execvp(), etc functions take a file name. dlopen() also takes a name. Ugly solutions (like reading the file and calling some function pointer) are OK.

  • Does writing program using global variables is safer?

    - by ZoZo123
    I was reading about buffer, stack and heap overflows. I read this post as well. my question is like that: if I use only global variables in my code, can I say it prevents all the exploits of overflow? let's say I have this buffers in code declared in the global scope: char buf1[10]; char buf2[100]; If I send buf1 as the buffer to recv(int s, char *buf, int len,int flags); I will overwrite the data segment and may ruin the buf2 content, right? Would I be able to run a code from it because as I know it is not a code segment and data segment is not executable. Can we conclude that using Globals is the safest way?

  • C program - Seg fault, cause of

    - by resonant_fractal
    Running this gives me a seg fault (gcc filename.c -lm), when i enter 6 (int) as a value. Please help me get my head around this. The intended functionality has not yet been implemented, but I need to know why I'm headed into seg faults already. Thanks! #include<stdio.h> #include<math.h> int main (void) { int l = 5; int n, i, tmp, index; char * s[] = {"Sheldon", "Leonard", "Penny", "Raj", "Howard"}; scanf("%d", &n); //Solve Sigma(Ai*2^(i-1)) = (n - k)/l if (n/l <= 1) printf("%s\n", s[n-1]); else { tmp = n; for (i = 1;;) { tmp = tmp - (l * pow(2,i-1)); if (tmp <= 5) { // printf("Breaking\n"); break; } ++i; } printf("Last index = %d\n", i); // ***NOTE*** //Value lies in next array, therefore ++i; index = tmp + pow(2, n-1); printf("%d\n", index); } return 0; }

  • Merge n files using a C program

    - by Amal
    I am writing a download Accelerator. So I download a file from the webserver into n parts. Now I want to merge the files into 1 single file. So I use the following code. And the file names are in the correct order. But the output file I am getting is different from the original download file. Can you tell me where could the error be ?C int cbd_merge_files(const char** filenames, int n, const char* final_filename) { FILE* fp = fopen(final_filename, "wb"); if (fp == NULL) return 1; char buffer[4097]; for (int i = 0; i < n; ++i) { const char* fname = filenames[i]; FILE* fp_read = fopen(fname, "rb"); if (fp_read == NULL) return 1; int n; while ((n = fread(buffer, sizeof(char), 4096, fp_read))) { int k = fwrite(buffer, sizeof(char), n, fp); if (!k) return 1; } fclose(fp_read); } fclose(fp); return 0; }

  • Recommendations for C++ open source game engines on IPhone

    - by Dave
    I decided that I want to make a game for the iphone I was thinking of using oolong or sio2 any recommendations? Both have the problem of lack of tutorials, is it possible to somehow use a normal C++ game tutorial and integreate the engines rather than the one used in the tutorials? So if the C++ tutorial talks of creating an engine I can skip it and use sio2 or oolong? Thanks

  • Global NSMutableArray doesn't seem to be holding values

    - by diatrevolo
    I have a Cocos2D iPhone application that requires a set of CGRects overlaid on an image to detect touches within them. "Data" below is a class that holds values parsed from an XML file. "delegateEntries" is a NSMutableArray that contains several "data" objects, pulled from another NSMutableArray called "entries" that lives in the application delegate. For some strange reason, I can get at these values without problems in the init function, but further down the class in question, I try to get at these values, and the application crashes without an error message (as an example, I put in the "ccTouchBegan" method which accessess this data through the "populateFieldsForTouchedItem" method. Can anyone see why these values would not be accessible from other methods? No objects get released until dealloc. Thanks in advance! @synthesize clicked, delegate, data, image, blurImage, normalImage, arrayOfRects, delegateEntries; - (id)initWithTexture:(CCTexture2D *)aTexture { if( (self=[super initWithTexture:aTexture] )) { arrayOfRects = [[NSMutableArray alloc] init]; delegateEntries = [[NSMutableArray alloc] init]; delegate = (InteractivePIAppDelegate *)[[UIApplication sharedApplication] delegate]; delegateEntries = [delegate entries]; data = [delegateEntries objectAtIndex:0]; NSLog(@"Assigning %@", [[delegateEntries objectAtIndex:0] backgroundImage]); NSLog(@"%@ is the string", [[data sections] objectAtIndex:0]); //CGRect rect; NSLog(@"Count of array is %i", [delegateEntries count]); //collect as many items as there are XML entries for(int i=0; i<[delegateEntries count]; i++) { if([[delegateEntries objectAtIndex:i] xPos]) { NSLog(@"Found %i items", i+1); [arrayOfRects addObject:[NSValue valueWithCGRect:CGRectMake([[[delegateEntries objectAtIndex:i] xPos] floatValue], [[[delegateEntries objectAtIndex:i] yPos] floatValue], [[[delegateEntries objectAtIndex:i] xBounds] floatValue], [[[delegateEntries objectAtIndex:i] yBounds] floatValue])]]; } else { NSLog(@"Nothing"); } } //remove the following once the NSMutableArray from above works (legacy) blurImage = [[NSString alloc] initWithString:[data backgroundBlur]]; NSLog(@"5"); normalImage = [[NSString alloc] initWithString:[data backgroundImage]]; clicked = NO; } return self; } And then: - (void)populateFieldsForTouchedItem:(TouchedRect)touchInfo { Data *touchDatum = [[Data alloc] init]; touchDatum = [[self delegateEntries] objectAtIndex:touchInfo.recordNumber]; NSLog(@"Assigning %@", [[[self delegateEntries] objectAtIndex:touchInfo.recordNumber] backgroundImage]); rect = [[arrayOfRects objectAtIndex:touchInfo.recordNumber] CGRectValue]; image = [[NSString alloc] initWithString:[[touchDatum sections] objectAtIndex:0]]; [touchDatum release]; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { TouchedRect touchInfo = [self containsTouchLocation:touch]; NSLog(@"Information pertains to %i", touchInfo.recordNumber); if ( !touchInfo.touched && !clicked ) { //needed since the touch location changes when zoomed NSLog(@"NOPE"); return NO; } [self populateFieldsForTouchedItem:touchInfo]; NSLog(@"YEP"); return YES; }

  • I need to make a multithreading program (python)

    import multiprocessing import time from itertools import product out_file = open("test.txt", 'w') P = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p','q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z',] N = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] M = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'] c = int(input("Insert the number of digits you want: ")) n = int(input("If you need number press 1: ")) m = int(input("If you need upper letters press 1: ")) i = [] if n == 1: P = P + N if m == 1: P = P + M then = time.time() def worker(): for i in product(P, repeat=c): #check every possibilities k = '' for z in range(0, c): # k = k + str(i[z]) # print each possibility in a txt without parentesis or comma out_file.write( k + '\n') # out_file.close() now = time.time() diff = str(now - then) # To see how long does it take print(diff) worker() time.sleep(10) # just to check console The code check every single possibility and print it out in a test.txt file. It works but I really can't understand how can I speed it up. I saw it use 1 core out of my quad core CPU so I thought Multi-threading might work even though I don't know how. Please help me. Sorry for my English, I am from Italy.

  • Why does this program require MSVCR80.dll?

    - by Runner
    #include <gtk/gtk.h> int main( int argc, char *argv[] ) { GtkWidget *window; gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_widget_show (window); gtk_main (); return 0; } I tried putting various versions of MSVCR80.dll under the same directory as the generated executable(via cmake),but none matched. Is there a general solution for this kinda problem? UPDATE Some answers recommend install the VS redist,but I'm not sure whether or not it will affect my installed Visual Studio 9, can someone confirm?

  • throwing exception from APCProc crashes program

    - by lazy_banana
    I started to do some research on how terminate a multithreaded application properly and I found those 2 post(first, second) about how to use QueueUserAPC to signal other threads to terminate. I thought I should give it a try, and the application keeps crashing when I throw the exception from the APCProc. Code: #include <stdio.h> #include <windows.h> class ExitException { public: char *desc; DWORD exit_code; ExitException(char *desc,int exit_code): desc(desc), exit_code(exit_code) {} }; //I use this class to check if objects are deconstructed upon termination class Test { public: char *s; Test(char *s): s(s) { printf("%s ctor\n",s); } ~Test() { printf("%s dctor\n",s); } }; DWORD CALLBACK ThreadProc(void *useless) { try { Test t("thread_test"); SleepEx(INFINITE,true); return 0; } catch (ExitException &e) { printf("Thread exits\n%s %lu",e.desc,e.exit_code); return e.exit_code; } } void CALLBACK exit_apc_proc(ULONG_PTR param) { puts("In APCProc"); ExitException e("Application exit signal!",1); throw e; return; } int main() { HANDLE thread=CreateThread(NULL,0,ThreadProc,NULL,0,NULL); Sleep(1000); QueueUserAPC(exit_apc_proc,thread,0); WaitForSingleObject(thread,INFINITE); puts("main: bye"); return 0; } My question is why does this happen? I use mingw for compilation and my OS is 64bit. Can this be the reason?I read that you shouldn't call QueueApcProc from a 32bit app for a thread which runs in a 64bit process or vice versa, but this shouldn't be the case.

  • How to debug iPhone project crash when there is no error message

    - by teepusink
    Hi, I am doing this iPhone app that works fine on the simulator. However, when I run it on a device in debug mode, it just crash without any error messages. How can I debug that? I heard about a flag we can set to help with this kind of situation but not sure what that flag is and how to set it. If I'm not mistaken I think what that flag does is put a break point automatically prior to crash. Thanks, Tee

  • MC75 using symbol.imaging.device libraries for program

    - by Christy
    UPDATE: I found another library in the Windows Mobile - CameraCaptureDialog - this did the job - never did figure out the zero length available devices... Hi all, I have a .net application running on a symbol mc75 (motorola) using the scanner. I am now trying to add functionality for the camera and I am running into issues. To find the 'devices' you are supposed to use the library's 'available devices' function. With the barcode it is symbol.barcode.devices.availabledevices and it returns two items (you can scan from the scanner or using the camera device) However, when I do the camera library it does not find any devices - symbol.imaging.devices.availabledevices returns 0 I can take a picture using the software on the mc75, so I know the functionality is there, I just can't figure out how to get to it programmatically.... Does anyone have any ideas? Thanks for any help!
