  • Implementing a recursive menu system a'la Joomla in CodeIgniter

    - by pettersolberg
    Hi I have some sites powered by Joomla, but with my current assignment I wanted to try something new and created with CodeIgniter a really basic CMS (just to suit my client's needs). Everything works fine except menus - multilevel menus like in Joomla, Drupal etc. with items and subitems... My question is: do you know of any tutorials or texts abut implementing such a structure. I've tried the recursion thinggy with while getting children's IDs move downwards from the parent while searching for the currently displayed item's ID. I've tried also the Drupalish way with having a path parameter enclosing ID's all the way from top to bottom '1/23/123/3'. But all in all it was just too chaotic - code something, try it out. If you have some idea on this topic - thanks in advice.

  • Does Boost work with IntervalZero RTX 2009?

    - by cs-79
    Hi all Rtx experts, Have anyone implemented hard real-time app on IntervalZero Rtx environment using Boost libraries? I wish to use the Boost `unordered` data structures instead of solely relying on STL::Vector. Or Array/Vector is the only data structure supported by Rtx? * Off topic question: Can we use STL::String instead of char pointer for string in Rtx? Thanks.

  • Compile Qt Project To Run On A Linux System

    - by ForgiveMeI'mAN00b
    I have a Qt project. It uses the cross platform libraries SDL, OpenGL and FLTK. I want to be able to compile the project so that it can run on a Linux computer. I'm looking at a bunch of articles I have seen so far two ways to do this. Use a cross compiler, which seems to me a rather complicated thing to setup and compile with, or, the other options, is to compile the project simply on a Linux computer, simply the Linux version of Qt creator/SDK. My question is, If I have a Qt project that uses only cross platform libraries, then is creating a Windows version easy as compiling it in Qt/Windows, and creating the Linux version as easy as doing it in Qt/Linux? PS. Please don't ask/complain about why I didn't just try to see if it works myself, I don't have any Linux OS's installed on my computer right now, and I don't want to risk going into the trouble of installing a whole new OS just to have it not work in the end.

  • c++ normalizing data sizes across systems

    - by Bocochoco
    I have a struct with three variables: two unsigned ints and an unsigned char. From my understanding, a c++ char is always 1 byte regardless of what operating system it is on. The same can't be said for other datatypes. I am looking for a way to normalize POD's so that when saved into a binary file, the resulting file is readable on any operating system that the code is compiled for. I changed my struct to use a 1-byte alignment by adding #pragma as follows: #pragma pack(push, 1) struct test { int a; } #pragma pack(pop) but that doesn't necessarily mean that int a is exactly 4 bytes on every os, I don't think? Is there a way to ensure that a file saved from my code will always be readable?

  • Books on data-intensive enterprise integration patterns

    - by Tristan
    I'm trying to understand design patterns used by data-intensive enterprise applications. A classic example is the financial industry, where system must consume, analyze, and execute on real-time financial data while providing information and configuration options to a broad set of traders and analysts. One can imagine similar system in airlines, major supply chain operations, and utility providers. Are there good books that provide and inside view of how these systems work? Enterprise Integration Patterns is one example, but I'm looking for something with more real-world applications, particularly in finance.

  • How to store array of NSManagedObjects in an NSManagedObject

    - by David Tay
    I am loading my app with a property list of data from a web site. This property list file contains an NSArray of NSDictionaries which itself contains an NSArray of NSDictionaries. Basically, I'm trying to load a tableView of restaurant menu categories each of which contains menu items. My property list file is fine. I am able to load the file and loop through the nodes structure creating NSEntityDescriptions and am able to save to Core Data. Everything works fine and expectedly except that in my menu category managed object, I have an NSArray of menu items for that category. Later on, when I fetch the categories, the pointers to the menu items in a category is lost and I get all the menu items. Am I suppose to be using predicates or does Core Data keep track of my object graph for me? Can anyone look at how I am loading Core Data and point out the flaw in my logic? I'm pretty good with either SQL and OOP by themselves, but am a little bewildered by ORM. I thought that I should just be able to use aggregation in my managed objects and that the framework would keep track of the pointers for me, but apparently not. NSError *error; NSURL *url = [NSURL URLWithString:@"http://foo.com"]; NSArray *categories = [[NSArray alloc] initWithContentsOfURL:url]; NSMutableArray *menuCategories = [[NSMutableArray alloc] init]; for (int i=0; i<[categories count]; i++){ MenuCategory *menuCategory = [NSEntityDescription insertNewObjectForEntityForName:@"MenuCategory" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *category = [categories objectAtIndex:i]; menuCategory.name = [category objectForKey:@"name"]; NSArray *items = [category objectForKey:@"items"]; NSMutableArray *menuItems = [[NSMutableArray alloc] init]; for (int j=0; j<[items count]; j++){ MenuItem *menuItem = [NSEntityDescription insertNewObjectForEntityForName:@"MenuItem" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *item = [items objectAtIndex:j]; menuItem.name = [item objectForKey:@"name"]; menuItem.price = [item objectForKey:@"price"]; menuItem.image = [item objectForKey:@"image"]; menuItem.details = [item objectForKey:@"details"]; [menuItems addObject:menuItem]; } [menuCategory setValue:menuItems forKey:@"menuItems"]; [menuCategories addObject:menuCategory]; [menuItems release]; } if (![[self managedObjectContext] save:&error]) { NSLog(@"An error occurred: %@", [error localizedDescription]); }

  • Help with MySQL database structure - user notification system

    - by Simon
    Hi, I'd like to send global notifications to my users (1000+ users) and allow them to close the notification box once they have read the message. Basically I may send one notification per week globally ie/ each user get the same message and they are not personal in nature. What is the best way to achieve this? Create 2 tables: **tb_messages** message_id massage_title message_content **tb_read_messages** user_id message_id is-read That way i can just show each user the current notifications that are not read? select * from tb_read_messages WHERE user_id = $user_id AND is-read = no OR is there a more efficient way? Thanks!!!

  • How to generate sample XML documents from their DTD or XSD?

    - by lindelof
    We are developing an application that involves a substantial amount of XML transformations. We do not have any proper input test data per se, only DTD or XSD files. We'd like to generate our test data ourselves from these files. Is there an easy/free way to do that? Edit There are apparently no free tools for this, and I agree that OxygenXML is one of the best tools for this.
