  • Xml schema, how to make sure one element exists with a specific attribute value

    - by pexxxy
    How do I enforce the existing of an element with a specific attribute value in the XML? For example: <events> <event type="system" desc="this is a system event"/> <event type="bla1" desc="this is bla1 event"/> <event type="bla2" desc="this is bla2 event"/> </events> I need a rule to make sure the event element with type attribute = 'system' exists (once). All other event elements are optional;

  • How do you create a generic method in a class?

    - by Seth Spearman
    Hello, I am really trying to follow the DRY principle. I have a sub that looks like this? Private Sub DoSupplyModel OutputLine("ITEM SUMMARIES") Dim ItemSumms As New SupplyModel.ItemSummaries(_currentSupplyModel, _excelRows) ItemSumms.FillRows() OutputLine("") OutputLine("NUMBERED INVENTORIES") Dim numInvs As New SupplyModel.NumberedInventories(_currentSupplyModel, _excelRows) numInvs.FillRows() OutputLine("") End Sub I would like to collapse these into a single method using generics. For the record, ItemSummaries and NumberedInventories are both derived from the same base class DataBuilderBase. I can't figure out the syntax that will allow me to do ItemSumms.FillRows and numInvs.FillRows in the method. FillRows is declared as Public Overridable Sub FillRows in the base class. Thanks in advance. EDIT Here is my end result Private Sub DoSupplyModels() DoSupplyModelType("ITEM SUMMARIES",New DataBlocks(_currentSupplyModel,_excelRows) DoSupplyModelType("DATA BLOCKS",New DataBlocks(_currentSupplyModel,_excelRows) End Sub Private Sub DoSupplyModelType(ByVal outputDescription As String, ByVal type As DataBuilderBase) OutputLine(outputDescription) type.FillRows() OutputLine("") End Sub But to answer my own question...I could have done this... Private Sub DoSupplyModels() DoSupplyModelType(Of Projections)("ITEM SUMMARIES") DoSupplyModelType(Of DataBlocks)("DATA BLOCKS") End Sub Private Sub DoSupplyModelType(Of T as DataBuilderBase)(ByVal outputDescription As String, ByVal type As T) OutputLine(outputDescription) dim type as New T(_currentSupplyModel,_excelRows) type.FillRows() OutputLine("") End Sub Is that right? Does the New T() work? Seth

  • Composite pattern in C++ problem

    - by annouk
    Hello! I have to work with an application in C++ similar to a phone book: the class Agenda with an STL list of Contacts.Regarding the contacts hierarchy,there is a base-class named Contact(an abstract one),and the derived classes Friend and Acquaintance(the types of contact). These classes have,for instance, a virtual method called getName,which returns the name of the contact. Now I must implement the Composite pattern by adding another type of contact,Company(being derived from Contact),which also contains a collection of Contacts(an STL list as well),that can be either of the "leaf" type(Friends or Acquaintances),or they can be Companies as well. Therefore,Company is the Compound type. The question is: how and where can I implement an STL find_if to search the contact with a given name(via getName function or suggest me smth else) both among the "leaf"-type Contact and inside the Company collection? In other words,how do I traverse the tree in order to find possible matches there too,using an uniform function definition? I hope I was pretty clear...

  • Get REST Call is not returning the string I put in url

    I have very simple code: using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Http; using System.Web.Http; namespace Calculator.Controllers { public class CalcController : ApiController { public string Get(string type) { return type; } } } And this is what it returns when I type in http://www.example.com/api/calc/test <string xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/" i:nil="true"/> When I use http://www.example.com/api/calc/?test=test it returns this: <string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">type</string> How to I make it so I can just do the top one instead of the bottom one?

  • Filtering NSMutableArray based on enum property

    - by Marty
    I've got an NSMutableArray filled with objects of type "GameObject". GameObject has a number of properties, one of which being "gameObjectType" . "gameObjectType" is of type GameObjectTypeEnum. I want to be able to filter this NSMutableArray so only GameObjects of a certain type are returned. I've got the following in place, but it's giving me a "BAD ACCESS" error: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"gameObjectType = %@", gameObjectType]; return [gameObjects filteredArrayUsingPredicate:predicate]; Is it possible to pass a "custom" type (ie, this enum I've defined) into the predicateWithFormat call?

  • Having trouble with multiple Jquery libraries

    - by user3716971
    I've seen the posts about the no conflict but I'm not very code savvy and can't figure it out alone. I'm having trouble making two libraries work together. At the top I have the 1.9.1 library which controls a news ticker, and a carousel. Near the bottom there is a library 1.6.1, which controls a Dribbble feed. If I remove 1.6.1 everything but the dribbble feed works, and if I remove the 1.9.1 the dribbble feed is the only thing that works. I uploaded the website for you guys to check out. If you could edit my code to make it work that would be amazing, I don't have much knowledge of jquery. This version has a working dribbble feed at the very bottom http://michaelcullenbenson.com/MichaelCullenBenson.com/index.html and this version has a broken feed and everything else works. http://michaelcullenbenson.com/MichaelCullenBenson.com/index2.html Help would be AMAZING as the dribbble feed is the last element I'm trying to finish on my homepage and I'll be able to move on. <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> <script type="text/javascript" src="js/jquery.innerfade.js"></script> <script type="text/javascript"> $(document).ready( function(){ $('#news').innerfade({ animationtype: 'slide', speed: 600, timeout: 6000, type: 'random', containerheight: '1em' }); }); </script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="utilcarousel-files/utilcarousel/jquery.utilcarousel.min.js"></script> <script src="utilcarousel-files/magnific-popup/jquery.magnific-popup.js"></script> <script src="js/responsive-nav.js"></script> <script> $(function() { $('#fullwidth').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); $('#fullwidth2').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); }); </script> <script> $(document).ready(function() { var movementStrength = 25; var height = movementStrength / $(window).height(); var width = movementStrength / $(window).width(); $("#aboutarea").mousemove(function(e){ var pageX = e.pageX - ($(window).width() / 2); var pageY = e.pageY - ($(window).height() / 2); var newvalueX = width * pageX * -1 - 25; var newvalueY = height * pageY * -1 - 50; $('#aboutarea').css("background-position", newvalueX+"px "+newvalueY+"px"); }); }); </script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script> <script type="text/javascript" src="dribbble.js"></script> <script type="text/javascript"> $(function () { $('#user').dribbble({ player: 'MCBDesign', total: 1 }); }); </script>

  • Sort objects and polymorphism

    - by ritmbo
    Suppose I have a class A. And B and C are child of A. Class A has a generic algorithm for sorting arrays of type A, so that I could use it for B and C without writing again the algorithm for each. In the algorithm, sometimes I have to swap. The problem is that I can only see the objects as type A, and if I do: A aux = array[i] array[i] = array[j] array[j] = aux I think I have a problem. Because array[i], maybe its of type B, and aux is of type A, so I think I'm losing information. I'm sure u understand this situation... how can I sort a generic array of objects using a father method algorithm?

  • MySQL - Exclude rows from Select based on duplication of two columns

    - by Carson C.
    I am attempting to narrow results of an existing complex query based on conditional matches on multiple columns within the returned data set. I'll attempt to simplify the data as much as possible here. Assume that the following table structure represents the data that my existing complex query has already selected (here ordered by date): +----+-----------+------+------------+ | id | remote_id | type | date | +----+-----------+------+------------+ | 1 | 1 | A | 2011-01-01 | | 3 | 1 | A | 2011-01-07 | | 5 | 1 | B | 2011-01-07 | | 4 | 1 | A | 2011-05-01 | +----+-----------+------+------------+ I need to select from that data set based on the following criteria: If the pairing of remote_id and type is unique to the set, return the row always If the pairing of remote_id and type is not unique to the set, take the following action: Of the sets of rows for which the pairing of remote_id and type are not unique, return only the single row for which date is greatest and still less than or equal to now. So, if today is 2010-01-10, I'd like the data set returned to be: +----+-----------+------+------------+ | id | remote_id | type | date | +----+-----------+------+------------+ | 3 | 1 | A | 2011-01-07 | | 5 | 1 | B | 2011-01-07 | +----+-----------+------+------------+ For some reason I'm having no luck wrapping my head around this one. I suspect the answer lies in good application of group_by, but I just can't grasp it. Any help is greatly appreciated!

  • How do disable Rails submit buttons alongside Prototype helpers & RJS?

    - by Jesse
    I'm trying to follow this post http://stackoverflow.com/questions/576240/how-can-i-unobtrusively-disable-submit-buttons-with-javascript-and-prototype but I can't get it to work. The form triggers an RJS function, so I need to keep the helpers' onclick events intact. The RJS returns/reloads the same forms along with two new texts. I'm really confused.

  • How to implement collection with covariance when delegating to another collection for storage?

    - by memelet
    I'm trying to implement a type of SortedMap with extended semantics. I'm trying to delegate to SortedMap as the storage but can't get around the variance constraints: class IntervalMap[A, +B](implicit val ordering: Ordering[A]) //extends ... { var underlying = SortedMap.empty[A, List[B]] } Here is the error I get. I understand why I get the error (I understand variance). What I don't get is how to implement this type of delegation. And yes, the covariance on B is required. error: covariant type B occurs in contravariant position in type scala.collection.immutable.SortedMap[A,List[B]] of parameter of setter underlying_=

  • Webview blank but content is there

    - by Scott Dugas
    I am having trouble displaying a webview. I have a webview inside a custom view. I load this custom view as a subview of the window, and then have an object controller linking a text field to the content of the web view. Once a page is loaded, it loads all the content, but it is visually white. You can click on links. If you go to a Youtube video you can listen to it, but it still displays nothing.

  • Why isn't the compiler smarter in this const function overloading problem?

    - by Frank
    The following code does not compile: #include <iostream> class Foo { std::string s; public: const std::string& GetString() const { return s; } std::string* GetString() { return &s; } }; int main(int argc, char** argv){ Foo foo; const std::string& s = foo.GetString(); // error return 0; } I get the following error: const1.cc:11: error: invalid initialization of reference of type 'const std::string&' from expression of type 'std::string* It does make some sense because foo is not of type const Foo, but just Foo, so the compiler wants to use the non-const function. But still, why can't it recognize that I want to call the const GetString function, by looking at the (type of) variable I assign it to? I found this kind of surprising.

  • Why is the 'var' keyword bad? Or am I just old school?

    - by WaggingSiberian
    Recently I overheard junior developer ask "why do you use 'var' so much?". The mid-level developer responded "I use VAR all the time. I love it! I don't have to figure out the type." I didn't have the time or energy to get into a religious war and hey, I'm still the new guy here :-) I understand var has its place. LINQ comes to mind. But I have also always been told the use of var represents lazy programming and I should just use the correct type to begin with. If it's an int, define it as an int, not a var. When reviewing code, seeing the type makes it easier to follow. My opinion is, it's just lazy but there are exception. Var also reminds me of the VB/VBA variant type. It also had its place. I recall (from many years ago) its usage being less-than-desirable type and it was rather resource hungry. Am I just being stuck in my ways? Should we start using var all the time as my co-worker does?

  • Maximum length of a std::basic_string<_CharT> string

    - by themoondothshine
    Hey all, I was wondering how one can fix an upper limit for the length of a string (in C++) for a given platform. I scrutinized a lot of libraries, and most of them define it arbitrarily. The GNU C++ STL (the one with experimental C++0x features) has quite a definition: size_t npos = size_t(-1); /*!< The maximum value that can be stored in a variable of type size_t */ size_t _S_max_len = ((npos - sizeof(_Rep_base))/sizeof(_CharT) - 1) / 4; /*!< Where _CharT is a template parameter; _Rep_base is a structure which encapsulates the allocated memory */ Here's how I understand the formula: The size_t type must hold the count of units allocated to the string (where each unit is of type _CharT) Theoretically, the maximum value that a variable of type size_t can take on is the total number of units of 1 byte (ie, of type char) that may be allocated The previous value minus the overhead required to keep track of the allocated memory (_Rep_base) is therefore the maximum number of units in a string. Divide this value by sizeof(_CharT) as _CharT may require more than a byte Subtract 1 from the previous value to account for a terminating character Finally, that leave the division by 4. I have absolutely no idea why! I looked at a lot of places for an explanation, but couldn't find a satisfactory one anywhere (that's why I've been trying to make up something for it! Please correct me if I'm wrong!!).

The document was parsed as HTML5. I think its funny. Okay, granted a tag that is closed and a self closing tag are not the same. So i would understand if jquery couldnt load. Altough i find it rediciulous. But what i do not understand is that jquery loads but the following, correctly written tag, doesnt?
