  • Removing object from NSMutableArray

    - by Ben Packard
    Just a small query... I stumbled across the following shortcut in setting up a for loop (shortcut compared to the textbook examples I have been using): for (Item *i in items){ ... } As opposed to the longer format: for (NSInteger i = 0; i < [items count]; i++){ ... } //think that's right If I'm using the shorter version, is there a way to remove the item currently being iterated over (ie 'i')? Or do I need to use the longer format?

  • Python: Data Object or class

    - by arg20
    I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

  • .Net in HTML tp return true if reader object not null, otherwise return false

    - by Phill Healey
    I'm using a DataList to show some data from the database and populating the fields on the html side. I now have a requirement to change the visibility of a panel based on whether or not a db field has data or not. I need to be able to show the panel if the relevant data field has content, and hide it if it doesn't. Eg: <asp:Panel ID="pnlNew" runat="server" Style="margin:0; padding:0; width:42px; height:18px; bottom:5px; right:10px; float:right; position:relative; background:url(../_imgVideoBadge.png) no-repeat;" Visible='<%# Eval("cheese") != null %>' ToolTip="available"></asp:Panel> Obviously this doesn't work in terms of the visible property. But hopefully it gives an idea of what I'm trying to achieve. Any help would be greatly appreciated. I've seen examples previously of doing something along the lines of: a ?? b:c How could this be applied to the above requirement?? Thanks in advance.

  • Do you draw the entire object?

    - by vbman11
    Hi I'm working on learning 3d game development and I'm starting with JavaScript and the html5 canvas and I was wondering if I were to have a 3d model do I draw the entire model(front, back, etc) and let the web browser decide what to render or should I try to just draw the sides that are in view of the camera? I ask this because I can see how it would be faster to do the latter of the 2 but that can get very complex and I'll need to do quite a bit more research to find how to do that. Thanks!!

  • Creating an Expando object in Ruby

    - by tyndall
    Is there a better way to write this Expando class? The way it is written does not work. I'm using Ruby 1.8.7 starting code quoted from https://gist.github.com/300462/3fdf51800768f2c7089a53726384350c890bc7c3 class Expando def method_missing(method_id, *arguments) if match = method_id.id2name.match(/(\w*)(\s*)(=)(\s*)(\.*)/) puts match[1].to_sym # think this was supposed to be commented self.class.class_eval{ attr_accessor match[1].to_sym } instance_variable_set("#{match[1]}", match[5]) else super.method_missing(method_id, *arguments) end end end person = Expando.new person.name = "Michael" person.surname = "Erasmus" person.age = 29

  • Recognizing synchronization object hanging two 3rd party executables

    - by eran
    I'm using a 3rd party tool, which uses a 4th party plugin. Occasionally, the tool will hang when launched. Looking at the stack traces, I can see a few threads are waiting on WaitForSingleObject, and my bet is that they're blocking each other. Some of the threads start at the 3rt party tool, and some at the 4th party plugin. What I'd like to do is file the most detailed complaint to the 3rd party tool vendor, assuming it's its fault (I don't trust their local support to get those details themselves). For that, I'd like to: Find out what are the synchronization objects currently waited on Find out who has created those synchronization objects Tools currently at hand are VS2005, WinDbg and Process Explorer. OS is Window 7 64 bit. Any suggestions?

  • jQuery replace first string match

    - by P4tient
    I have an array, like var acronyms = { 'NAS': 'Nunc ac sagittis', 'MTCP': 'Morbi tempor congue porta' }; I need to find first match of each acronym and wrap around with tag via jQuery. E.g. <div id="wrap">NAS dui pellentesque pretium augue. MTCP pellentesque pretium augue. NAS ac ornare lectus MTCP nec.</div> becomes <div id="wrap"><acronym title="Nunc ac sagittis">NAS</acronym> dui pellentesque pretium augue. <acronym title="Morbi tempor congue porta">MTCP</acronym> pellentesque pretium augue. NAS ac ornare lectus MTCP nec.</div> Thanks.

  • How to add a suffix at the end of a string in PHP

    - by Golem
    I am trying to add a .html suffix at the end of all strings supplied by the user before it is entered into the database. Here's my code so far: strtolower(str_replace(" ", "_", $postTitle)); The above takes the title of the post the user it trying to make, turns it to lower case, replaces all white spaces with underscores and makes it ready to be entered into a database column called post_url. I just need it to do one more thing and that's to add a .html at the end of each post url. What is the function to do this?

  • Object Recognition from Templates

    - by JonLeah
    Hi Guys, I was hoping someone could point me in the right direction here. With a picture of a die (from above) I want to recognize which side is up. I understand the basics in play here, but I'm having trouble grasping the power of OpenCV. I imagine I want a picture of each side of the die. Then I can somehow compare them all to the current image to be classified. How can I use OpenCV to do this? Thanks, Jonathan

  • Returning reference to object is not changing the address in c++

    - by ashish-sangwan
    I am trying to understand functions returning a reference. For that I have written a simple program: #include<iostream> using namespace std; class test { int i; friend test& func(); public: test(int j){i=j;} void show(){cout<<i<<endl;} }; test& func() { test temp(10); return temp; //// Address of temp=0xbfcb2874 } int main() { test obj1(50); // Address of obj1=0xbfcb28a0 func()=obj1; <= Problem:The address of obj1 is not changing obj1.show(); // // Address of obj1=0xbfcb28a0 return 0; } I ran the program using gdb and observed that the address of obj1 still remains same, but I expect it to get changed to 0xbfcb2874. I am not clear with the concept. Please help.

  • Is String.concat slower than Array approach to join strings

    - by Rajat
    Strings in JavaScript are immutable. Across the web and here on Stack Overflow as well, I came across the Array approach to concatenate strings: var a = []; a.push(arg1,arg,2....); console.log(a.join('')); I know that this approach is better than the simple console.log(arg1 + arg2 +.....); for reasons of skipping creating intermediate objects but how does it fair better against : arg1.concat(arg2,arg3.....);

  • PHP Object Access Syntax Question with the $

    - by ImperialLion
    I've been having trouble searching for this answer because I am not quite sure how to phrase it. I am new to PHP and still getting my feet on the ground. I was writing a page with a class in it that had the property name. When I originally wrote the page there was no class so I just had a variable called $name. When I went to encapsulate it in a class I accidental changed it to be $myClass->$name. It tool me a while to realize that the syntax I needed was $myClass->name. The reason it took so long was the error I kept getting was "Attempt to access a null property" or something along those lines. The error lead me to believe it was a data population error. My question is does $myClass->$name have a valid meaning? In other words is there a time you would use this and a reason why it doesn't create a syntax error? If so what is the semantic meaning of that code? When would I use it if it is valid? If its not valid, is there a reason that it doesn't create a syntax error?

  • iPhone/Obj-C - Archiving object causes lag

    - by Dylan
    Hi I have a table view, and when I delete a cell I am removing an item from an NSMutableArray, archiving that array, and removing the cell. However, when I do this, it is causing the delete button to lag after I click it. Is there any way to fix this? // Override to support editing the table view. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { int row = [indexPath row]; [savedGames removeObjectAtIndex:row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; //this line causing lag [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } Thanks

  • Object-oriented Programming - need your help

    - by wanderameise
    hey folks, I try to realize a little game project to dive deeper into OO programming (winforms c++/cli). I already started coding but now I´d like to make a re-design. For the beginning the game should consist of four parts like game-engine, user interface, highscore and playground. Heres a little (non-UML-conform) class diagramm to visualize my purposes http://i.imgur.com/lmpwj.png Would this be the right way? In my eyes the game engine is responsible to control the game sequences (state machine?) and exchanges information betweens all other classes. I appreciate any help!

  • Linq to NHibernate - How to return a parent object with only certain child objects included

    - by vakman
    Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

    - by Mark
    I have a simple iPhone app that Im learning and I want to have an instance variable called urlLists which is an NSDictionary I have declared it like so: @interface MyViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate>{ IBOutlet UIPickerView *pickerView; NSMutableArray *categories; NSDictionary *urlLists; } @property(retain) NSDictionary *urlLists; @end and in the implementation: @implementation MyViewController @synthesize urlLists; ... - (void)viewDidLoad { [super viewDidLoad]; categories = [[NSMutableArray alloc] init]; [categories addObject:@"Sport"]; [categories addObject:@"Entertainment"]; [categories addObject:@"Technology"]; [categories addObject:@"Political"]; NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", @"value3", @"value4", nil]; urlLists = [NSDictionary dictionaryWithObjects:objects forKeys:categories]; for (id key in urlLists) { NSLog(@"key: %@, value: %@", key, [urlLists objectForKey:key]); } } ... @end And, this all works up to here. I have added a UIPicker to my app, and when I select one of the items, I want to Log the one picked and its related entry in my dictionary. -(void) pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger) component { for (id key in self.urlLists) { NSLog(@"key: %@, value: %@", key, [urlLists objectForKey:key]); } } but I get the old EXC_BAD_ACCESS error... I know Im missing something small, but what? Thanks
