  • How can I catch a "catchable fatal error" on PHP type hinting?

    - by Ho
    Hello, I am trying to implement Type Hinting of PHP5 on one of my class, class ClassA { public function method_a (ClassB $b) {} } class ClassB {} class ClassWrong{} Correct usage: $a = new ClassA; $a->method_a(new ClassB); producing error: $a = new ClassA; $a->method_a(new ClassWrong); Catchable fatal error: Argument 1 passed to ClassA::method_a() must be an instance of ClassB, instance of ClassWrong given... May I know if it is possible to catch that error(since it says "catchable")? and if yes, how? Thank you.

  • Initialize a static member ( an array) in C++

    - by Jimmy zhang
    I intended to create a class which only have static members and static functions. One of the member variable is an array. Would it be possible to initialize it without using constructors? I am having lots of linking errors right now... Class A{ public: static char a[128]; static void do_something(); } How would you initialize a[128]? Why can't I initialize a[128] by directly specifying its value like in C? a[128={1,2,3,...};

  • JAX-RS implementation of link/element expansion?

    - by Jimmy
    While reading documentation of Google Data API and Atlassian REST API, I found interesting functionality - link (or title, element expansion) - http://bit.ly/i3rKMw. I would like to implement this functionality in my Java project of web service server for our IS, but I can't find any proper solution or advices for implementation. My project is quite big with many services so I need some robust and most automated solution. I was thinking about how to implement it like an extension for RESTEasy and JAXB, but it seems to be very complicated. Do you know some opensource projects which implements this functionality or any advices which could help me?

  • Convert text box text into Argb argument

    - by Jimmy
    I have been looking into coloring objects like ellipses with code such as SolidBrush trnsRedBrush = new SolidBrush(Color.FromArgb(0x78FF0000)); I'd like to play around further with this by entering FromArgb's argument into a textbox on a form, then using the textbox to set the Brush's color. How would I convert the textbox's text into an argument usable by FromArgb?

  • Migrating from a single entity to an abstract parent entity with child entities, NSEntityMigrationPolicy not called.

    - by Jimmy Selgen Nielsen
    Hi. I'm trying to upgrade my current application to use an abstract parent entity, with specialized sub entities. I've created a custom NSEntityMigrationPolicy, and in the mapping model I've set the Custom Policy to the name of my class. I'm initializing my persistent store like this, which should be fairly standard : NSError *error=nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]]; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, nil]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Error adding persistent store : %@",[error description]); NSAssert(error==nil,[error localizedDescription]); } When i run the app i get the following error : Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The operation couldn’t be completed. (Cocoa error 134140.)' [error userInfo] contains "reason=Can't find mapping model for migration" I've verified that version 1 of the data model will open, and if i set NSInferMappingModelAutomaticallyOption i get a migration, although my entities are not migrated correctly (as expected). I've verified that the mapping model (cdm) is in the application bundle, but somehow it refuses to find it. I've also set breakpoints and NSLog() statements in the custom migration policy, and none of it runs, with or without NSInferMappingModelAutomaticallyOption Any hints as to why it seems unable to find the mapping model ?

  • How to check whether a CGPoint is inside a UIImageView?

    - by Horace Ho
    In touchesBegan: CGPoint touch_point = [[touches anyObject] locationInView:self.view]; There are tens of UIImageView around, stored in a NSMutableArray images. I'd like to know is there a built-in function to check if a CGPoint (touch_point) is inside one of the images, e.g.: for (UIImageView *image in images) { // how to test if touch_point is tapped on a image? } Thanks Follow up: For unknown reason, pointInside never returns true. Here is the full code. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; touch_point = [touch locationInView:self.view]; for (UIImageView *image in piece_images) { if ([image pointInside:touch_point withEvent:event]) { image.hidden = YES; } else { image.hidden = NO; } NSLog(@"image %.0f %.0f touch %.0f %.0f", image.center.x, image.center.y, touch_point.x, touch_point.y); } } although I can the two points are sometimes identical in the NSLog output ... I also tried: if ([image pointInside:touch_point withEvent:nil]) the result is the same. never returns a true. To eliminate the chance of anything goes with with the images. I tried the following: if (YES or [image pointInside:touch_point withEvent:event]) all images are hidden ater the first click on screen.

  • decoding algorithm wanted

    - by Horace Ho
    I receive encoded PDF files regularly. The encoding works like this: the PDFs can be displayed correctly in Acrobat Reader select all and copy the test via Acrobat Reader and paste in a text editor will show that the content are encoded so, examples are: 13579 -> 3579; hello -> jgnnq it's basically an offset (maybe swap) of ASCII characters. The question is how can I find the offset automatically when I have access to only a few samples. I cannot be sure whether the encoding offset is changed. All I know is some text will usually (if not always) show up, e.g. "Name:", "Summary:", "Total:", inside the PDF. Thank you!

  • What are some lesser known usages of #pragma?

    - by Xavier Ho
    I've never understood the need of #pragma once when #ifndef #define #endif always works. I've seen the usage of #pragma comment to link with other files , but setting up the compiler settings was easier with an IDE. What are some other usages of #pragma that is useful, but not widely known?

  • Which PHP framework for a RoR developer?

    - by Horace Ho
    For one specific client I have to use PHP. This and this question were 2 years old. I'd like to know is there any update of opinion for year 2010? My background on web development is mainly rails. I can code in PHP (for example, write a module for Drupal) but never used any PHP framework for any project. I can see the following potential features to be needed in my project: authlogic-like user access control will_paginate-like paging for long listings paperclip-like simple file upload prawn-like PDF generation restful url and my personal favorite ruby/rails features: activerecord <% @list.each do |item| %> synstax instead of for ($i=1; $i<=$row_num; $i++) ... rake:db migrate script/console Thanks!
