• How do browsers/PHP handle characters outside the set characterset?

  - by Maarten

  I'm looking into how characters are handled that are outside of the set characterset for a page. In this case the page is set to iso-8859-1, and the previous programmer decided to escape input using htmlentities($string,ENT_COMPAT). This is then stored into Latin1 tables in Mysql. As the table is set to the same character set as the page, I am wondering if that htmlentities step is needed. I did some experiments on http://floris.workingweb.nl/experiments/characters.php and it seems that for stuff inside Latin1 some characters are escaped, but for example with a Czech name they are not. Is this because those characters are outside of Latin1? If so, then the htmlentities can be removed, as it doesn't help for stuff outside of Latin1 anyway, and for within Latin1 it is not needed as far as I can see now...

• Hidden Features and Dark Corners of STL?

  - by Andrei

  C++ developers, all know the basics of C++: Declarations, conditionals, loops, operators, etc. Some of us even mastered the stuff like templates, object model, complex I/O, etc. But what are the most hidden features or tricks or dark corners of C++/STL that even C++ fans, addicts, and experts barely know? I am talking about a seasoned C++ programmer (be she/he a developer, student, fan, all three, etc), who thinks (s)he knows something 99% of us never heard or dreamed about. Something that not only makes his/her work easier, but also cool and hackish. After all, C++ is one of the most used programming languages in the world, thus it should have intricacies that only a few privileged know about and want to share with us. Boost is welcome too! One per post with an example please P.S Examples are important for other developers to copy and paste!

• Extremely basic PHP and Mysql

  - by fighella

  Background: I am more of a designer than a programmer, but have hacked templates for many open source CMS's (Drupal, Joomla, Wordpress) I want to start from scratch in regards to the relations of php and a mysql database. Lets assume I have a working database and php engine locally. What would be my first step to connecting to my database and creating a table... (im happy to be led to an appropriate tutorial...) Many of the tutorials I have seen start with basic php, but I would rather explore the connection between the db and the php.

• code to edit the text ib an EditText widgit

  - by user293663

  Hello, I am a newbi programmer and am having trouble with a measurement conversion program I am working on. What I would like to do is have several EditText boxes. When one is filled in and a calculate button is hit then the rest will be populated with a converted number. The part I am getting stuck on is outputting the answers to EditText widgets. ex: There are three EditText Widgets. a user inputs the number 6 into the first one (labeled inches) and presses calculate. I would like the next box to display .5 (labeled feet) and the last to display .1666 (this would be yards) .setText() apparently does not work to modify the text in an EditText any help would be greatly appreciated.

• PHP specifying a fixed include source for scripts in different directories

  - by Extrakun

  I am currently doing unit testing, and use folders to organize my test cases. All cases pertaining to managing of user accounts, for example, go under \tests\accounts. Over time, there are more test cases, and I begin to seperate the cases by types, such as \tests\accounts\create, \tests\account\update and etc. However, one annoying problem is I have to specify the path to a set of common includes. I have to use includes like this: include_once ("../../../../autoload.php"); include_once ("../../../../init.php"); A test case in tests\accounts\ would require change to the include (one less directory level down). Is there anyway to have them somehow locating my two common includes? I understand I could set include paths within my PHP's configurations, or use server environment variables, but I would like to avoid such solutions as they make the application less portable and coupled with another layer which the programmer can't control (some web-host doesn't allow configuration of PHP's configuration settings, for example)

• Resources for TDD aimed at Python Web Development

  - by Null Route

  I am a hacker not and not a full-time programmer but am looking to start my own full application development experiment. I apologize if I am missing something easy here. I am looking for recommendations for books, articles, sites, etc for learning more about test driven development specifically compatible with or aimed at Python web application programming. I understand that Python has built-in tools to assist. What would be the best way to learn about these outside of RTFM? I have searched on StackOverflow and found the Kent Beck's and David Astels book on the subject. I have also bookmarked the Wikipedia article as it has many of these types of resources. Are there any particular ones you would recommend for this language/application?

• (For what) Are Fortran, Cobol and Co. used today?

  - by lamas

  I'm a relatively young programmer and so I don't really know much about languages like Fortran or Cobol that have their origins in the beginning of modern informatics. I'm a bit confused because it seems like there are many people out there saying that these two languages are still very alive and being used all over the world whereas others say the opposite. In addition, it seems like there are only very few questions tagged Fortran or Cobol here on stackoverflow. Can someone "demystify" the situation for me? Who uses these senior languages these days and are they even used anymore? Do you have any experiences with one of the languages or do you know something about their latest developments?

• How can an animator do animation targeted for the iPhone

  - by teepusink

  Hi, I'm working with an animator for the iPhone. The animator I'm working with isn't a programmer and has a background in Flash. (right now she's doing the animation in Flash and I need to convert to Objective C). For some it's ok because I can just use image frames, but there are more complex animation that would take longer for me to convert to Objective C. Is there any tools out there that can help the work flow easier? Just trying to find a way so I can just take the animation and stick it into the project. Thanks, Tee

• java.lang.UnsupportedClassVersionError in eclipse

  - by Derek

  Hi all, I am not a Java programmer really, so I am posting this question. The exception is being thrown java.lang.UnsupportedClassVersionError in my main class in an eclipse project. If I comment out the imports that this class has, it compiles and runs fine. If I put the imports back in, it does not work. Does this mean that the libraries I am importing were compiled with a newer or older version of java than I have? when i do java -version on the system i get 1.5_07 I could've sworn this was actually working last week, but maybe some setting in eclipse got tweaked? Is the Java Build Path in eclipse what I need to look for to check the JRE and compiler versions?

• Determining Connections between data in a single table

  - by user1689749

  Hi I'm a BA / programmer type doing data analysis on a legacy system. I've been teaching myself SQL to help, but I've appeared to hit upon a problem bigger than my abilities. I have two tables (generalized for simplicity): Table Objects Object_PK Table Components Component_PK Object_FK Component_Type There are 100+ distinct values in Component_Type_Code. Given that any object can have N number of Components, how can I see which Component_Type(s) appear with other Component_Type(s)? For example, the following query tells me what component_types appear with the component_type 'Component_type_1': select component_type_code, count(*) from components where object_fk in ( select object_fk from components where component_type_code = 'component_type_1' ) group by component_type_code I'd like to get a query to show me all connections My apologies for the formatting. Any help is appreciated. I've looked at cube and rollup, but didn't know how to apply to this situtation.

• How do I get the sums of the digits of a large number in Haskell?

  - by Tim

  I'm a C++ Programmer trying to teach myself Haskell and it's proving to be challenging grasping the basics of using functions as a type of loop. I have a large number, 50!, and I need to add the sum of its digits. It's a relatively easy loop in C++ but I want to learn how to do it in Haskell. I've read some introductory guides and am able to get 50! with sum50fac.hs:: fac 0 = 1 fac n = n * fac n - 1 x = fac 50 main = print x Unfortunately at this point I'm not entirely sure how to approach the problem. Is it possible to write a function that adds (mod) x 10 to a value and then calls the same function again on x / 10 until x / 10 is less than 10? If that's not possible how should I approach this problem? Thanks!

• [Django] How to find out whether a model's column is a foreign key?

  - by codethief

  I'm dynamically storing information in the database depending on the request: // table, id and column are provided by the request table_obj = getattr(models, table) record = table_obj.objects.get(pk=id) setattr(record, column, request.POST['value']) The problem is that request.POST['value'] sometimes contains a foreign record's primary key (i.e. an integer) whereas Django expects the column's value to be an object of type ForeignModel: Cannot assign "u'122'": "ModelA.b" must be a "ModelB" instance. Now, is there an elegant way to dynamically check whether b is a column containing foreign keys and what model these keys are linked to? (So that I can load the foreign record by it's primary key and assign it to ModelA?) Or doesn't Django provide information like this to the programmer so I really have to get my hands dirty and use isinstance() on the foreign-key column?

• display classes of a namespace in visual studio (C#)

  - by ericyoung7001

  I am a Java programmer, and just starting to use Visual Studio to do C# programming. In Java IDE such as Eclipse, if I do not know the classname in a package, I can just type a dot (.) after a package name, then I will get a list of all the classes in that package in the IDE. How I can configure visual studio to do the similar thing, say, if I click a namespace name in a file (for example, using System), or add a dot after the namespace, all the classes in that namespace will be displayed somewhere in the IDE?

• C# Lists, Foreach, and Types

  - by user406470

  I was wondering if there is a version of foreach that checks only for a specific type and returns it. For example consider this class tree: org.clixel.ClxBasic - org.clixel.ClxObject - org.clixel.ClxSprite - WindowsGame1.test Then consider this code public List<ClxBasic> objects = new List<ClxBasic>(); foreach(GroupTester tester in objects) { tester.GroupTesterOnlyProperty = true; } tester.GroupTesterOnlyProperty is a property created in GroupTester. Is there some way to make something like this work, like an overload of foreach, or another snippet that might help me? I want to make it easy for a programmer to sort through the lists grabbing only what type they need.

• Does an Intent's extras still get flattened into a Parcel even if the new activity is being started

  - by Neil Traft

  I was wondering... So if you start a new activity via an intent, the intent has to be serialized and deserialized because you may have to send the intent to a separate VM instance via IPC. But what if the PackageManager knows that your new activity will be created on the current task? It seems like a reasonably Googly optimization would be not to serialize the intent at all, since it's all happening inside the same VM. But then again, you can't just allow the new activity to use the same instance of each parcelable, because any changes made by the new activity would show up in the old activity and the programmer might not be expecting this. So, is this optimization being done? Or do the extras always get marshalled and unmarshalled, no matter what?

• Rank Source Control Options-VSS vs CVS vs none vs your own hell

  - by Roman A. Taycher

  It seems like a lot of people here and on many programmer wikis/blogs/ect. elsewhere really dislike VSS. A lot of people also have a serious dislike for cvs. In many places I have heard a lot of differing opinions on whether or not using VSS or cvs is better or worse then using no source control, please rate the worst and explain why!!!!! you rated them this way. Feel free to throw in your own horrible system in the rankings. If you feel it depends on the circumstances try to explain the some of the different scenarios which lead to different rankings. (note:I see a lot of discussion of what is better but little of what is worse.) second note: while both answers are nice I'm looking less for good replacements and more for a comparison of which is worse and more importantly why!

• Is wrapping new within the constructor good or bad?

  - by Timothy

  I watched John Resig's Best Practices in JavaScript Library Design presentation; one slide suggested "tweaking" the object constructor so it instantiates itself. function jQuery(str, con) { if (window === this) { return new jQuery(str, con); } // ... } With that, new jQuery("#foo") becomes jQuery("# foo"). I thought it was rather interesting, but I haven't written a constructor like that in my own code. A little later I read a post here on SO. (Sorry, I don't remember which or I'd supply a link. I will update the question if I can find it again.) One of the comments said it was bad practice to hide new from the programmer like that, but didn't go into details. My question is, it the above generally considered good, bad, or indifferent, and why?

• Upgrade SQLServer 2008 hardware

  - by John

  Forgive me if I'm not able to be totally clear here. It is not intentional, I'm a senior level developer in a very small company having to act like a manager at the moment. Anyway, the story is that we have 2 older dell servers with SQL Server 2008 Standard in a "cluster". I put that in quotes because I'm still not 100% clear what that means. We have 2 brand new blade servers and want to move the existing databases to the new hardware. Ok, so here is the gotcha. We need to do this with little or no down time. I'm being told that we can evict the passive node, then pull in one of the new servers. But I'm also being told that this is a dangerous step because something could go wrong that would cause the cluster to fail and then we would be left with nothing because the active server would not be able to come back up. Does anyone have any thoughts on how to handle this? I'm being told that the only way to ensure success is to have at least a day of down time where we bring up a new cluster on the new hardware and then migrate the databases 1 by 1.

• Easiest, free way to start with Flex?

  - by Jon

  I'm interested in getting started with Flex, as I've wanted to work with flash for quite awhile but have never liked the designer-oriented way of programming. I've heard flex can be used for free, and is programmer friendly, but I'm having some issues... I can't find any good sites with flex resources. I'm used to PHP, so maybe I'm spoiled with a full manual, comments and tutorials, but I can't even find a decent tutorial site. So, what are some good flex starts to get started, and what's a good, free IDE to program with?

• SQL Server: Primary Key Schema Largely Guid but Sometimes Integer Types...

  - by Code Sherpa

  OK, this may be a silly question but... I have inherited a project and am tasked with going over the primary key relationships. The project largely uses Guids. I say "largely" because there are examples where tables use integral types to reflect enumerations. For example, dbo.MessageFolder has MessageFolderId of type int to reflect public emum MessageFolderTypes { inbox = 1, sent = 2, trash = 3, etc... } This happens a lot. There are tables with primary keys of type int which is unavoidable because of their reliance on enumerations and tables with primary keys of type Guid which reflect the primary key choice on the part of the previous programmer. Should I care that the PK schema is spotty like this? It doesn't feel right but does it really matter? If this could create a problem, how do I get around it (I really can't move all PKs to type int without serious legwork and I have never heard of enumerations that have guid values)? Thanks.
