• UIImageView in UITableCell gets a weird size

  - by Behlül

  Hi, I'm trying to place a UIImageView in a UITableViewCell. I create a special view called ProductView. In that view, I have several components, one of them being a UIImageView. I set this ProductView as content view of the UITableViewCell. Everything is drawn properly except the UIImageView. UIImageView gets scaled meaninglessly. It's height gets twice the height of the table cell size. I've spent hours trying to solve this problem. I've set the frame of UIImageView manually, I've called drawRect method of UIImage in UIImageView, neither of them worked. I'm thinking of replacing UITableView with a UIScrollView if I can't find a solution. Does anyone know how to solve this problem?

• Is there anything wrong with my Factory class?

  - by Alex

  class PieceFactory { @SuppressWarnings("rawtypes") public Piece createPiece(String pieceType) throws Throwable{ Class pieceClass = Class.forName(pieceType); Piece piece = (Piece) pieceClass.newInstance(); return piece; } } I'm not all used to handling exceptions yet therefore I'm just throwing them, but everywhere I use a method that uses this factory it tells me I have to throw exceptions like throwable. For example, in one of my classes I have a method that instantiates a lot of objects using the method that uses the factory. I can use the method in that class by just throwing the exception, however it won't work if I try to pass a reference to that class to another class and then use the method from there. Then it forces me to try catch the exception. I probably don't need a factory but it seemed interesting and I'd like to try to use patterns. The reason I created the factory was that I have 6 subclasses of Piece and I wan't to use a method to instantiate them by passing the type of subclass I want as an argument to the method.

• Spotting similarities and patterns within a string - Python

  - by RadiantHex

  Hi folks, this is the use case I'm trying to figure this out for. I have a list of spam subscriptions to a service and they are killing conversion rate and other usability studies. The emails inserted look like the following: [email protected] [email protected] [email protected] roger[...]_surname[...]@hotmail.com What would be your suggestions on spotting these entries by using an automated script? It feels a little more complicated than it actually looks. Help would be very much appreciated!

• NSCollectionView: Can the same object not be in the array more than once or is this a bug?

  - by Sean

  I may be doing this all wrong, but I thought I was on the right track until I hit this little snag. Basically I was putting together a toy using NSCollectionView and trying to understand how to hook that all up using IB. I have a button which will add a couple of strings to the NSArrayController: The first time I press this button, my strings appear in the collection view as expected: The second time I press the button, the views scroll down and room is made - but the items don't appear to get added. I just see blank space: The button is implemented as follows (controller is a pointer to the NSArrayController I added in IB): - (IBAction)addStuff:(id)control { [controller addObjects:[NSArray arrayWithObjects:@"String 1",@"String 2",@"String 3",nil]]; } I'm not sure what I'm doing wrong. Rather than try to explain all the connections/binds/etc, if you need more info, I'd be grateful if you could just take a quick look at the toy project itself. UPDATE: After more experimentation as suggested by James Williams, it seems the problem stems from having multiple objects with the same memory address in the array. This confuses either NSArrayController or NSCollectionView (not sure which). Changing my addStuff: to this resulted in the behavior I originally expected: [controller addObjects:[NSArray arrayWithObjects:[NSMutableString stringWithString:@"String 1"],[NSMutableString stringWithString:@"String 2"],[NSMutableString stringWithString:@"String 3"],nil]]; So the question now, I guess, is if this is a bug I should report to Apple or if this is intended/documented behavior and I just missed it?

• Python: Elegant way to check if at least one regex in list matches a string

  - by houbysoft

  Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

• Accessing the Identity object in a MVC repository

  - by Rod

  Hi, I have a pretty generic repository that does basic CRUD for many of my business entities. The entities enherit form a generic object that has a few fields I maintain for all objects. eg. ModifiedBy, CreatedBy, CreatedDate, ModifiedDate. These fields ModifiedBy and CreatedBy will always be set before any update/save. My questions is: Is there any way to gain access to the Identity object from my MVC web application in my repositories? I was hoping to set the modifiedby to the identity user for any update in one shot?? Best Regard, Rod

• Calculating probability that a string has been randomized? - Python

  - by RadiantHex

  Hi folks, this is correlated to a question I asked earlier (question) I have a list of manually created strings such as: lucy87 gordan_king fancy_unicorn77 joplucky_kanga90 base_belong_to_narwhals and a list of randomized strings: johnkdf pancake90kgjd fancy_jagookfk manhattanljg What gives away that the last set of strings are randomized is that sequences such as 'kjg', 'jgf', 'lkd', ... . Any clever way I could separate strings that contain these apparently randomized strings from the crowd? I guess that this plays a lot on the fact that certain characters are more likely to be placed next to others (e.g. 'co', 'ka', 'ja', ...). Any ideas on this one? Kylotan mentioned Reverend, but I am not sure if it can be used fr such purpose. Help would be much appreciated!

• Count word occurrences in a text field with LINQ

  - by Yoann. B

  How can i get the occurrences count of a Word in a database text field With LINQ ? Keyword token sample : ASP.NET EDIT 4 : Database Records : Record 1 : [TextField] = "Blah blah blah ASP.NET bli bli bli ASP.NET blu ASP.NET yop yop ASP.NET" Record 2 : [TextField] = "Blah blah blah bli bli bli blu ASP.NET yop yop ASP.NET" Record 3 : [TextField] = "Blah ASP.NET blah ASP.NET blah ASP.NET bli ASP.NET bli bli ASP.NET blu ASP.NET yop yop ASP.NET" So Record 1 Contains 4 occurrence of "ASP.NET" keyword Record 2 Contains 2 occurrence of "ASP.NET" keyword Record 3 Contains 7 occurrence of "ASP.NET" keyword Collection Extraction IList < RecordModel (ordered by word count descending) Record 3 Record 1 Record 2 LinqToSQL should be the best, but LinqToObject too :) NB : No issue about the "." of ASP.NET keyword (this is not the goal if this question)

• regex and javascript, some matches disappear !

  - by dader51

  Here is the code : > var reg = new RegExp(" hel.lo ", 'g'); > > var str = " helalo helblo helclo heldlo "; > > var mat = str.match(reg); > > alert(mat); It alerts "helalo, helclo", but i expect it to be "helalo, helblo, helclo, heldlo" . Only the half of them matches, I guess that's because of the space wich count only once. So I tried to double every space before processing, but in some case it's not enough. I'm looking for an explanation, and a solution. Thx

• Converting a navbar to a tabbar app

  - by Nick

  Hey guys, I was wondering how to convert a NavigationController style app into a TabBarcontroller style app. I changed my mainwindow to not contain a navigationcontroller anymore (but a tabbarcontroller instead) and my delegate also appropiatly, but when I launch the app something still thinks I want a navigationController: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key navigationController.'

• Fluent NHibernate Repository with subclasses

  - by reallyJim

  Having some difficulty understanding the best way to implement subclasses with a generic repository using Fluent NHibernate. I have a base class and two subclasses, say: public abstract class Person { public virtual int PersonId { get; set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } } public class Student : Person { public virtual decimal GPA { get; set; } } public class Teacher : Person { public virtual decimal Salary { get; set; } } My Mappings are as follows: public class PersonMap : ClassMap { public PersonMap() { Table("Persons"); Id(x => x.PersonId).GeneratedBy.Identity(); Map(x => x.FirstName); Map(x => x.LastName); } } public class StudentMap : SubclassMap<Student> { public StudentMap() { Table("Students"); KeyColumn("PersonId"); Map(x => x.GPA); } } public class TeacherMap : SubclassMap<Teacher> { public TeacherMap() { Table("Teachers"); KeyColumn("PersonId"); Map(x => x.Salary); } } I use a generic repository to save/retreive/update the entities, and it works great--provided I'm working with Repository--where I already know that I'm working with students or working with teachers. The problem I run into is this: What happens when I have an ID, and need to determine the TYPE of person? If a user comes to my site as PersonId = 23, how do I go about figuring out which type of person it is?

So, basically I want the autocomplete form the receive the mouse click message when the users clicks, but to never become active, because it causes problems with a third-party component in the main form over which I have no control.

• Will NKDbgPrintfW be compiled to nop in release build?

  - by Johann Gerell

  I know about and have used the macros DEBUGMSG, RETAILMSG, ERRORMSG, that all take a condition parameter. For general formatted debug output, though, I want to use ::NKDbgPrintfW directly and wonder if someone knows if it compiles to a nop in optimised release builds or if my own macro wrapper around it with #ifdef DEBUG is still needed?

• Using explicitly numbered repetition instead of question mark, star and plus

  - by polygenelubricants

  I've seen regex patterns that use explicitly numbered repetition instead of ?, * and +, i.e.: Explicit Shorthand (something){0,1} (something)? (something){1} (something) (something){0,} (something)* (something){1,} (something)+ The questions are: Are these two forms identical? What if you add possessive/reluctant modifiers? If they are identical, which one is more idiomatic? More readable? Simply "better"?

• Making a view scrollable when keyboard active

  - by Dan Ray

  I have a view with half a dozen text fields and labels, and a button. I want it to be that when the keyboard pops up, the view becomes scrollable, so you can scroll the view up and see the bottom half of the fields without having to dismiss the keyboard to get to them. Just putting it inside a UIScrollView doesn't seem to do it.

• Using jQuery to find keywords in string

  - by Nic Hubbard

  In php, I have used preg_match_all() to find keywords (using the format %keyword%) in a string, which works wonderfully and returns an array of all found keywords. What I would like to do, is do the same thing using jQuery or javascript. I have tried using the filter() function, and it kind of works. But I think I am missing something. How can I find ALL instances of the keyword in a string, using a regex? Here is what I have worked out so far: $("[id^='editableContent-']").filter(function() { alert($(this).html().match(/\%(.*?)\%/)); }); Any suggestions are welcome!
