  • Weird ViewControllers - iPhone SDK

    - by Kevin
    Hello everyone, I have a Tab-Bar Application for this iPhone application I am making. I make a simple button on the 3rd view (3rd tab), and give it an IBAction to give an alert view. When I press build and go, everything works out fine. I go onto the 3rd tab, and I press my button. It simply crashes... Why is this happening? Everything I put in this 3rd tab crashes. I create a simple view controller, and write the class files to start over, but I keep getting the same errors.. Everything works fine on my first tab, where I originally got the first view controller.. P.S It also says Incomplete Implementation of Class 'ThirdViewController'. I don't know why its there.. If anyone can help me out here, i would greatly appreciate it. Kevin

  • How can I store an inventory-like list of numbers?

    - by Rachel
    I've got a list of number that I need to keep track of. The numbers are loosely related, but represent distinctly different items. I'd like to keep a list of the numbers but be able to refer to them by name so that I can call them and use them where needed easily. Kind of like an inventory listing, where the numbers all refer to a part ID and I'd like to call them idPart1, idPart2, idPart3 so their purpose is easily identifiable when they are used. What would be the best way to do this? 1)Define a structure. Say, PartIds. A number of int members will be included, part1, part2 etc. To use, an instance of the structure will be created, values assigned to the members, and the numbers will be used by saying struct.member as needed. 2)Define an enumeration. Use part1, part2 as the enum literals. Store the actual values in a vector or list, each one at the index corresponding to the value of the number's name within the enum. Use the enum literals to retrieve the values, list[enumLit]. 3)Something completely different There's nothing else I need to do with the numbers - just look them up every once in a while. Since there's no processing, I kind of think a new class for them is overkill, but I'm willing to be convinced otherwise. Any suggestions?

  • nHibernate one-to-many inserts but doesnt update

    - by user210713
    Instead of getting into code, I have a simple question. Default behavior for a simple one-to-many is that it inserts the child record then updates the foreign key column with the parent key. Has anyone ever had a one-to-many where the child object gets inserted but not updated resulting in a row in my table with a null in the foreign key column? I want the default behaviour for a standard one-to-many. I don't want to have to add the parent as a property to the child. Thanks.

  • Example of standalone Apache Qpid (amqp) Junit Test

    - by Wiretap
    Does anyone have an example of using Apache Qpid within a standalone junit test. Ideally I want to be able to create a queue on the fly which I can put/get msgs within my test. So I'm not testing QPid within my test, I'll use integration tests for that, however be very useful to test methods handling msgs with having to mock out a load of services.

  • nHibernate query looking for the related object's related object

    - by code-zoop
    I have an nHibernate querie issue that looks quite straight forward, but I can't seem to get my head around it! I am creating some simple example classes to illustrate my problem: public class Car { public int Id { get; set; } public IList<Interior> InteriorParts { get; set; } } public class Interior { public int Id { get; set; } public InteriorProducer Producer { get; set; } } public class InteriorProducer { public int Id { get; set; } } Now to the query: I have the id of the InteriorProducer, but need to get a list of Cars where the interior have been produced by the interior producer. So in a simple, pseudo SQL, it looks something like this: select cars where car.InteriorParts.Producer.Id = Id I have a really hard time getting my head around this to create an nHibernate query. Any Ideas? Thanks

  • How is Java Platform independent when it needs JVM to run ?

    - by happysoul
    Just started learning Java and I am confused about this whole independent platform thingy. Doesn't independent means that Java code should be able to run on any machine and would need no special software to be installed (JVM in this case has to be present in the machine)? Like, for example, we need to have Turbo C Compiler in order to compile C/C++ source code and then execute it.. The machine has to have the C compiler. guess I am confused..Somebody please explain in simple language or may be direct me to a tutorial that explain things in simple language ? that would be great I am just not getting the concept.

  • PHP: How To call Standard Library Functions

    - by Andi
    Hi, I'm starting with PHP for dynamic web pages. I have some libaries written in ANSI C for getting/setting parameters and other proprietary stuff. I wonder, is there a simple solution to use a wrapper inside PHP to call this funtions? Is there a already existing class/library? What would be the best practice to do this on my own? I don't want do make calls to external applications and use stdin/stdout! Is there a simple example available? I don't want to dig through the Zend documentation for now, I only need a feeling for the complexity. Thanks, kind regards, Andi

  • How to handle concurrency control in ASP.NET Dynamic Data?

    - by Andrew
    I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

  • Aggregate Functions and Group By Problems

    - by David Stein
    If we start with the following simple SQL statement which works. SELECT sor.FPARTNO, sum(sor.FUNETPRICE) FROM sorels sor GROUP BY sor.FPARTNO FPartNo is the part number and the Funetprice is obviously the net price. The user also wants the description and this causes a problem. If I follow up with this: SELECT sor.FPARTNO, sor.fdesc, sum(sor.FUNETPRICE) FROM sorels sor GROUP BY sor.FPARTNO, sor.fdesc If there are multiple variations of the description for that part number, typically very small variations in the text, then I don't actually aggregate on the part number. Make sense? I'm sure this must be simple. How can I return the first fdesc that corresponds to the part number? Any of the description variations would suffice as they are almost entirely identical. Edit: The description is a text field.

  • Can I make Visual Studio's code completion window more like Eclipse (Java)?

    - by Matt
    Is it possible to make Visual Studio 2010's code completion window more like that of Eclipse (Java)? In particular, I'd love the code completion window to give me a variable's type, and a method's return type and expected parameters, without needing to hover the highlight over that particular variable/method. VS's code completion's little icons that indicate if something is a property, method etc are useful, but they just aren't enough.

  • Should the PHP community start using more descriptive Exceptions?

    - by fireeyedboy
    I work with Zend Framework a lot and I just took a peek at Kohana, and it strikes me as odd that this is a typical scenario in these frameworks: throw Some_Componenents_Exception( 'invalid argument' ); Where I believe this wouldn't be mouch more useful: throw Some_Components_InvalidArgumentException( 'whatever discription' ); Because it is easier to catch. I suspect, but immediately admit it's prejudiced, that the former practice is common in the PHP community. Should we, the PHP community, start using these descriptive types of expections more?

  • How to map a Entity Data Model conceptual model property to a storage model column using the "Serial

    - by codekaizen
    I have a conceptual model in EDM where one of the entities has a property which is essentially a big value object whose properties aren't really useful as columns in the datamodel. I'd like to apply the Serialized LOB pattern to it so that I can fit it into a 192 byte binary column. How do I map this in the EDM v4? Is it even possible at this time? Actually, is it possible in any ORM?

  • Facebook charset detection mechanism?

    - by Void
    Today, I have looked into HTML code of facebook.com, and found something like this: <input type="hidden" value="€,´,€,´,?,?,?" name="charset_test"/> It's repeated two times inside the <form>...</form>. Any idea what this code might be useful for - some kind of server-side client charset detection? As far as I know, browser charset is being transmitted in HTTP request anyway (an "Accept-Charset" header).

  • Solve equation from string to result in C

    - by Alexandre Cassagne
    Hi, I would like to know if anyone has info or experience on how to do something which sounds simple but doesn't look like it when trying to program it. The idea is : give a string containing an equation, such as : "2*x = 10" for example (this is simple, but it could get very complex, such as sqrt(54)*35=x^2; and so on....) and the program would return x = 5 and possibly give a log of how he got there. Is this doable ? If so, does anyone have a lead ? For info there is this site (http://www.numberempire.com/equationsolver.php) which does the same thing in PHP, but isn't open source. Thanks for any help !

  • C# Parsing html for general use?

    - by Wardy
    What is the best way to take a string of html and turn it in to something useful? Essentially if i take a url and go get the html from that url in .net i get a response but this would come in the form of either a file or stream or string. What if i want an actual document or something I can crawl like an xmldocument object? I have some thoughts and an already implemented solution on this but I am interested to see what the community thinks about this.

  • Good guidelines for developing an ecommerce application

    - by kaciula
    I'm making an ecommerce application on Android and, as it is my first serious project, I'm trying to figure out beforehand the best approach to do this. The application talks to a web service (magento api, meaning soap or xml rpc unfortunately) and gets all the content on the phone (product categories, product details, user credentials etc.). I think it should do lazy loading or something like that. So, I was thinking to keep the user credentials in a custom Object which will be kept in a SharedPreferences so that every Activity cand easily access it. I'll use a couple of ListViews to show the content and AsyncTask to fetch the data needed. Should I keep all the data in memory in objects or should I use some sort of cache or a local database? Also, I'm planning to use a HashMap with SoftReferences to hold the bitmaps I am downloading. But wouldn't this eat a lot of memory? How cand all the activities have access to all these objects (ecommerce basket etc.)? I'm thinking of passing them using Intents but this doesn't seem right to me. Can SharedPreferences be used for a lot of objects and are there any concurrency issues? Any pointers would be really appreciated. What are some good guidelines? What classes should I look into? Do you know of any resources on the Internet for me to check out?

  • jQuery-ui themeroller base2.css

    - by cf_PhillipSenn
    I'm learning jQuery-UI, and would like to put together a good looking page, so I'm looking at base2.css from the themeroller site. Q: Is there anything anyone can tell me about base2.css? Is there any documentation on it? How much is specific to only the themeroller site itself, and how much of it is useful for sites that use themeroller themes?
