  • XSL-FO: is XSL-FO dead technology and only used by niche companies?

    - by MMAmail.com
    I wanted to convert some xml to a magazine like pdf document. A lot like what Latext allows you to do however i was not able to find any new books or online tutorials on the subject. Is it worth investing in using this technology or not? Also, I looked at the Apache XSL-FO project and their last release was in august 2008. p.s. commercial packages are not an option :(

  • Java 6 ScriptEngine and JSON.parse problem

    - by Tim
    The Rhino release that is included in Java 6 ScriptEngine does not have a JSON parser. I've tried including crockfords JSON2.js in my script on the scriptengine.eval(). When I try to do the JSON.parse, it ends up giving me a script error that .replace is an unknown function. .replace is referenced several places in JSON2, and it works fine inside a browser (IE7, IE8, FF3). Anyone see this and have a suggestion?

  • How to check Linux version with Autoconf?

    - by Goofy
    My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features). I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm: Run "uname --release" and store output Parse output and subtract Linux version number (MAJOR.MINOR.MICRO) Compare version I don't know how to run command, store output and parse it. Maybe such macro already exists and it's available (I haven't found any)?

  • How to manually throw a compiler error in GCC and Xcode

    - by coneybeare
    In xcode, while compiling apps with gcc, I want to throw compilation time errors if things like NSZombieEnabled is on for a distribution release, thus ensuring that compilation will fail and I won't accidentally do something stupid. I did some googling, but could not figure out how to cause the compiler to bail if a certain condition is met. Surely it must be easy, am I just not finding it?

  • JQuery templating engines

    - by Maurice
    I am looking for a template engine to use client side. I have been trying a few like jsRepeater and jQuery Templates. While they seem to work OK in FireFox they all seem to break down in IE7 when it comes down to rendering HTML tables. I also took a look at MicrosoftAjaxTemplates.js (from http://www.codeplex.com/aspnet/Release/ProjectReleases.aspx?ReleaseId=16766) but turns out that has the same problem. Any advice on other templating engines to use?

  • Obj-C memory management: why doesn't this work?

    - by igul222
    Why doesn't the following code work? MyViewController *viewController = [[MyViewController alloc] init]; [myWindow addSubview:viewController.view]; [viewController release]; As I understand, myWindow should be retaining viewController.view for as long as the window needs it. So why does this cause my app to crash on launch? (commenting out the last line fixes the problem, as expected)

  • iPhone noob - setting NSMutableDictionary entry inside Singleton?

    - by codemonkey
    Yet another iPhone/Objective-C noob question. I'm using a singleton to store app state information. I'm including the singleton in a Utilities class that holds it (and eventually other stuff). This utilities class is in turn included and used from various view controllers, etc. The utilities class is set up like this: // Utilities.h #import <Foundation/Foundation.h> @interface Utilities : NSObject { } + (id)GetAppState; - (id)GetAppDelegate; @end // Utilities.m #import "Utilities.h" #import "CHAPPAppDelegate.h" #import "AppState.h" @implementation Utilities CHAPPAppDelegate* GetAppDelegate() { return (CHAPPAppDelegate *)[UIApplication sharedApplication].delegate; } AppState* GetAppState() { return [GetAppDelegate() appState]; } @end ... and the AppState singleton looks like this: // AppState.h #import <Foundation/Foundation.h> @interface AppState : NSObject { NSMutableDictionary *challenge; NSString *challengeID; } @property (nonatomic, retain) NSMutableDictionary *challenge; @property (nonatomic, retain) NSString *challengeID; + (id)appState; @end // AppState.m #import "AppState.h" static AppState *neoAppState = nil; @implementation AppState @synthesize challengeID; @synthesize challenge; # pragma mark Singleton methods + (id)appState { @synchronized(self) { if (neoAppState == nil) [[self alloc] init]; } return neoAppState; } + (id)allocWithZone:(NSZone *)zone { @synchronized(self) { if (neoAppState == nil) { neoAppState = [super allocWithZone:zone]; return neoAppState; } } return nil; } - (id)copyWithZone:(NSZone *)zone { return self; } - (id)retain { return self; } - (unsigned)retainCount { return UINT_MAX; //denotes an object that cannot be released } - (void)release { // never release } - (id)init { if (self = [super init]) { challengeID = [[NSString alloc] initWithString:@"0"]; challenge = [NSMutableDictionary dictionary]; } return self; } - (void)dealloc { // should never be called, but just here for clarity [super dealloc]; } @end ... then, from a view controller I'm able to set the singleton's "challengeID" property like this: [GetAppState() setValue:@"wassup" forKey:@"challengeID"]; ... but when I try to set one of the "challenge" dictionary entry values like this: [[GetAppState() challenge] setObject:@"wassup" forKey:@"wassup"]; ... it fails giving me an "unrecognized selector sent..." error. I'm probably doing something really obviously dumb? Any insights/suggestions will be appreciated.

  • MacRuby + Interface Builder: How to display, then close, then display a window again

    - by Derick Bailey
    I'm a complete n00b with MacRuby and Cocoa, though I've got more than a year of Ruby experience, so keep that in mind when answering - I need lots of details and explanation. :) I've set up a simple project that has 2 windows in it, both of which are built with Interface Builder. The first window is a simple list of accounts using a table view. It has a "+" button below the table. When I click the + button, I want to show an "Add New Account" window. I also have an AccountsController < NSWindowController and a AddNewAccountController class, set up as the delegates for these windows, with the appropriate button click methods wired up, and outlets to reference the needed windows. When I click the "+" button in the Accounts window, I have this code fire: @add_account.center @add_account.display @add_account.makeKeyAndOrderFront(nil) @add_account.orderFrontRegardless this works great the first time I click the + button. Everything shows up, I'm able to enter my data and have it bind to my model. however, when I close the add new account form, things start going bad. if I set the add new account window to release on close, then the second time I click the + button, the window will still pop up but it's frozen. i can't click any buttons, enter any data, or even close the form. i assume this is because the form's code has been released, so there is no message loop processing the form... but i'm not entirely sure about this. if i set the add new account window to not release on close, then the second time i click the + button, the window shows up fine and it is usable - but it still has all the data that i had previously entered... it's still bound to my previous Account class instance. what am I doing wrong? what's the correct way to create a new instance of the Add New Account form, create a new Account model, bind that model to the form and show the form, when I click the + button on the Accounts form? ... this is all being done on OSX 10.6.6, 64bit, with XCode 3.2.4

  • UIImageWriteToSavedPhotosAlbum showing memory leak with iPhone connected to Instruments

    - by user168739
    Hi, I'm using version 3.0.1 of the SDK. With the iPhone connected to Instruments I'm getting a memory leak when I call UIImageWriteToSavedPhotosAlbum. Below is my code: NSString *gnTmpStr = [NSString stringWithFormat:@"%d", count]; UIImage *ganTmpImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:gnTmpStr ofType:@"jpg"]]; // Request to save the image to camera roll UIImageWriteToSavedPhotosAlbum(ganTmpImage, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil); and the selector method - (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { NSString *message; NSString *title; if (!error) { title = @"Wallpaper"; message = @"Wallpaper Saved"; } else { title = @"Error"; message = [error description]; } UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; } Am I forgetting to release something once the image has been saved and the selector method imageSavedToPhotosAlbum is called? Or is there a possible known issue with UIImageWriteToSavedPhotosAlbum? Here is the stack trace from Instruments: Leaked Object: GeneralBlock-3584 size: 3.50 KB 30 MyApp start 29 MyApp main /Users/user/Desktop/MyApp/main.m:14 28 UIKit UIApplicationMain 27 UIKit -[UIApplication _run] 26 GraphicsServices GSEventRunModal 25 CoreFoundation CFRunLoopRunInMode 24 CoreFoundation CFRunLoopRunSpecific 23 GraphicsServices PurpleEventCallback 22 UIKit _UIApplicationHandleEvent 21 UIKit -[UIApplication sendEvent:] 20 UIKit -[UIWindow sendEvent:] 19 UIKit -[UIWindow _sendTouchesForEvent:] 18 UIKit -[UIControl touchesEnded:withEvent:] 17 UIKit -[UIControl(Internal) _sendActionsForEvents:withEvent:] 16 UIKit -[UIControl sendAction:to:forEvent:] 15 UIKit -[UIApplication sendAction:toTarget:fromSender:forEvent:] 14 UIKit -[UIApplication sendAction:to:from:forEvent:] 13 CoreFoundation -[NSObject performSelector:withObject:withObject:] 12 UIKit -[UIBarButtonItem(Internal) _sendAction:withEvent:] 11 UIKit -[UIApplication sendAction:to:from:forEvent:] 10 CoreFoundation -[NSObject performSelector:withObject:withObject:] 9 MyApp -[FlipsideViewController svPhoto] /Users/user/Desktop/MyApp/Classes/FlipsideViewController.m:218 8 0x317fa528 7 0x317e3628 6 0x317e3730 5 0x317edda4 4 0x3180fc74 3 Foundation +[NSThread detachNewThreadSelector:toTarget:withObject:] 2 Foundation -[NSThread start] 1 libSystem.B.dylib pthread_create 0 libSystem.B.dylib malloc I did a test with a new project and only added this code below in the viewDidLoad: NSString *gnTmpStr = [NSString stringWithFormat:@"DefaultTest"]; UIImage *ganTmpImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:gnTmpStr ofType:@"png"]]; // Request to save the image to camera roll UIImageWriteToSavedPhotosAlbum(ganTmpImage, nil, nil, nil); The same leak shows up right after the app loads Thank you for the help.

  • Recursive SQL giving ORA-01790

    - by PenFold
    Using Oracle 11g release 2, the following query gives an ORA-01790: expression must have same datatype as corresponding expression: with intervals(time_interval) AS (select trunc(systimestamp) from dual union all select (time_interval + numtodsinterval(10, 'Minute')) from intervals where time_interval < systimestamp) select time_interval from intervals; The error suggests that the datatype of both subqueries of the UNION ALL are returning different datatypes. Even if I cast to TIMESTAMP in each of the subqueries, then I get the same error. What am I missing?

  • What is the status of ZendX (Specifically ZendX_JQuery) ?

    - by Doron
    I need to have an autocomplete functionality using jquery, and I've encountered ZendX_JQuery which has such functionality available. However, I've noticed that the entire ZendX_JQuery classes, are a bit old (the default jquery version is 1.3.2, and jquery ui 1.7.1). (see http://framework.zend.com/svn/framework/extras/branches/release-1.10/library/ZendX/JQuery.php) Should I use that instead of my own written code to include the jquery library and etc., and should I use the ZendX_JQuery_View_Helper_AutoComplete class for such functionality ?
