  • Trying to create C++/CLI assembly for use in .NET

    - by Bad Man
    I'm trying to bring a C++ library into C#, so naturally I am trying to make a C++/CLI project. In visual studio I created a new project (Visual C++ project, class library). I then tried to make a test class out of the pre-generated "Class1" namespace Test { public ref class TestIt { public: void DoWork() { System::Console::WriteLine("sup"); } // TODO: Add your methods for this class here. }; } So I compile in and go to the build folder.... hrmm no .dll wetf?? There's a .dll.intermediate.manifest file, but no .dll. So wut I did wrong?

  • Where should I put interface?

    - by Roman
    I program a class in which I have a method which takes an callback object from an external software. At the moment Eclipse says that it does not know the type of the object I gave as argument (it is expectable since I do not specify this type, it's done by the external software). So, I think I need to write an interface for the object which I give as an argument to my method. In this respect I have two questions. Is it really so? Can I solve the mentioned problem in the mentioned way. If it is the case, where should I put this interface? In the same file where my class is? In the class? Outside of the class?

  • Serializing an extended form object

    - by andyperfect
    I've been reading up on this whole subject, but I never came across this specific problem. I already understand that the whole idea of serializing an entire form is a horrible idea and just doesn't work. But, I am encountering a bit of a different problem. I have a class that inherits the "button" form object, that I call DataButton. Now for my problem. I want to be able to serialize this class, but I don't need any of the information from the actual button class. Is there any way to bypass the fact that I can't set the button form object to Serializable() and notify VB that when serialization is to occur, it should simply skip over that information? Theoretically, if such a procedure were possible, I'd be able to do the entire serialization without a hitch. I came up with the idea earlier of removing the "inherits" feature from the class, and having simply a button within the class, but that makes my program really difficult to work with as I am constantly changing the location, size, backgroundImage, text, and whatnot. Thus, immediate updates would be much tougher to work with. Any help would be greatly appreciated.

  • C# Constructor Problem When Using Generics

    - by Jimbo
    Please see an example of my code below: public class ScrollableCheckboxList { public List<ScrollableCheckboxItem> listitems; public void ScrollableCheckboxList<TModel>(IEnumerable<TModel> items, string valueField, string textField, string titleField) where TModel : class { listitems = new List<ScrollableCheckboxItem>(); foreach (TModel item in items) { Type t = typeof(TModel); PropertyInfo[] props = new [] { t.GetProperty(textField), t.GetProperty(valueField), t.GetProperty(titleField) }; listitems.Add(new ScrollableCheckboxItem { text = props[0].GetValue(item, null).ToString(), value = props[1].GetValue(item, null).ToString(), title = props[2].GetValue(item, null).ToString() }); } } } The code produces the following error: 'ScrollableCheckboxList': member names cannot be the same as their enclosing type This clearly means that there is a method in the class that has the same name as the class, but usually insinuates that the method is trying to return something (which is not allowed) In my case, all I have done is declare a constructor - why would this be a problem?

  • JQuery going through a set of UL and dynamically set ids incremently on each one

    - by Calibre2010
    I have an unordered list which contains serveral items called 'oListItems' the UL has a class but no id. The class OuteroListItems contains many of oListitems oList.AppendFormat("<ul class='OuteroListItems'>"); oList.AppendFormat("<li>"); oList.AppendFormat("<ul class='oListItems'>"); oList.AppendFormat("<li>" + s.sName + "</li>"); oList.AppendFormat("<li>" + s.eName + "</li>"); oList.AppendFormat("<li>" + s.SDate + "</li>"); oList.AppendFormat("<li>" + s.EDate + "</li>"); oList.AppendFormat("</ul>"); oList.AppendFormat("</li>"); oList.AppendFormat("</ul>"); I want for each .oListItem class that gets retrieved, add dynamically an id to it. var o = $(".oListItem"); $.each(o, function (){ var f = $(this).attr("id", 'listItem' + i); i++; }); wasent sure on the approach, this is what I have so far?

  • Extended Zend_Db_Table_Row_Abstract does not return values

    - by WesleyE
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName for this row (Is on another table), just for example } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • C++ Newbie Question

    - by JavaMan
    I am from a Java background and is learning C++. I encountered the following C++ code: String source = String::New("'Hello' + ', World'"); As what I understand so far, this should be a call to static member function 'New' of class 'String'. But, I've searched through the whole header file defining 'String', there is not any static member named 'New' in the String class or its super classes. Is there any special meaning attached to String class or the New member function in C++?

I've published the asp.net application, loaded it to the webserver root. all ok. Now for the service, I've created a new folder on the root called WCF, and placed the aplication in there. Is this The way I should deploy the sollution? Are this the steps when you have more than a simple asp.net application? PS: How do I change that WCF folder to make it an application trough a control panel because I get this:http://surveillancecamera.somee.com/WCF. The reason why I get this is described here:

  • Scala : reference is ambiguous (imported twice)

    - by tk
    I want to use a method as a parameter of another method of the same class. I have a class and objects which are companions: class mM(var elem:Matrix){ //apply a function on a dimension rows (1) or cols (2) def app(func:Iterable[Double]=>Double)(dim : Int) : Matrix = { ... } //utility function def logsumexp(): Double = {...} } object mM{ def apply(elem:Matrix):mM={new mM(elem)} def logsumexp(elem:Iterable[Double]): Double ={ this.apply(elem.asInstanceOf[Matrix]).logsumexp() } } Normally I use logsumexp like this mM(matrix).logsumexp but if want to apply it to the rows I can't use mM(matrix).app(mM.logsumexp)(1), I get the error: error: reference to mM is ambiguous; it is imported twice in the same scope by import mM and import mM What is the most elegant solution ? Should I change logsumexp() to another class ? Thanks,=)

  • Bootstrap inline button dropdown within <p> jumbotron

    - by C.B.
    Currently I have a jumbotron setup with some paragraph text, and I would like to stick a button dropdown inline with the text. Dropdown button <span class="btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"> Button... <span class="caret"></span> </button> <ul class="dropdown-menu" role="menu"> <li><a href="#">Opt 1</a></li> <li><a href="#">Opt 2</a></li> </ul> </span> Jumbotron <div class="jumbotron"> <h1>Hello!</h1> <p>Welcome</p> <p>Another paragraph <!-- dropdown is here --> </p> </div> <!-- jumbotron --> If the dropdown is within the <p> tag, it does not "dropdown" (but renders). If it is outside of the <p> tag it functions fine, but I would like it to be inline with the text and need the text to be in the <p> tag to get the style. Any ideas? Things to note -- If I replace the <span> tags with <div> tags, it will work fine within the <p> tags, but won't be inline.

  • When does logic belong in the Business Object/Entity, and when does it belong in a Service?

    - by Casey
    In trying to understand Domain Driven Design I keep returning to a question that I can't seem to definitively answer. How do you determine what logic belongs to a Domain entity, and what logic belongs to a Domain Service? Example: We have an Order class for an online store. This class is an entity and an aggregate root (it contains OrderItems). Public Class Order:IOrder { Private List<IOrderItem> OrderItems Public Order(List<IOrderItem>) { OrderItems = List<IOrderItem> } Public Decimal CalculateTotalItemWeight() //This logic seems to belong in the entity. { Decimal TotalWeight = 0 foreach(IOrderItem OrderItem in OrderItems) { TotalWeight += OrderItem.Weight } return TotalWeight } } I think most people would agree that CalculateTotalItemWeight belongs on the entity. However, at some point we have to ship this order to the customer. To accomplish this we need to do two things: 1) Determine the postage rate necessary to ship this order. 2) Print a shipping label after determining the postage rate. Both of these actions will require dependencies that are outside the Order entity, such as an external webservice to retrieve postage rates. How should we accomplish these two things? I see a few options: 1) Code the logic directly in the domain entity, like CalculateTotalItemWeight. We then call: Order.GetPostageRate Order.PrintLabel 2) Put the logic in a service that accepts IOrder. We then call: PostageService.GetPostageRate(Order) PrintService.PrintLabel(Order) 3) Create a class for each action that operates on an Order, and pass an instance of that class to the Order through Constructor Injection (this is a variation of option 1 but allows reuse of the RateRetriever and LabelPrinter classes): Public Class Order:IOrder { Private List<IOrderItem> OrderItems Private RateRetriever _Retriever Private LabelPrinter _Printer Public Order(List<IOrderItem>, RateRetriever Retriever, LabelPrinter Printer) { OrderItems = List<IOrderItem> _Retriever = Retriever _Printer = Printer } Public Decimal GetPostageRate { _Retriever.GetPostageRate(this) } Public void PrintLabel { _Printer.PrintLabel(this) } } Which one of these methods do you choose for this logic, if any? What is the reasoning behind your choice? Most importantly, is there a set of guidelines that led you to your choice?

  • C++ CRTP question

    - by aaa
    following piece of code does not compile, the problem is in T::rank not be inaccessible (I think) or uninitialized in parent template. Can you tell me exactly what the problem is? is passing rank explicitly the only way? or is there a way to query tensor class directly? Thank you #include <boost/utility/enable_if.hpp> template<class T, // size_t N, class enable = void> struct tensor_operator; // template<class T, size_t N> template<class T> struct tensor_operator<T, typename boost::enable_if_c< T::rank == 4>::type > { tensor_operator(T &tensor) : tensor_(tensor) {} T& operator()(int i,int j,int k,int l) { return tensor_.layout.element_at(i, j, k, l); } T &tensor_; }; template<size_t N, typename T = double> // struct tensor : tensor_operator<tensor<N,T>, N> { struct tensor : tensor_operator<tensor<N,T> > { static const size_t rank = N; }; I know the workaround, however am interested in mechanics of template instantiation for self-education

  • Events + Adapter Pattern

    - by Stretto
    I have an adapter pattern on a generic class that essentially adapts between types: class A<T> { event EventHandler e; } class Aadapter<T1, T2> : A<T1> { A<T2> a; Aadapter(A<T2> _a) { a = _a; } } The problem is that A contains an event. I effectively want all event handlers assigned to Adapter to fall through to a. It would be awesome if I could assign the a's event handler to adapter's event handler but this is impossible? The idea here is that A is almost really just A but we need a way to adapt the them. Because of the way event's work I can't how to efficiently do it except manually add two event handlers and when they are called they "relay" the to the other event. This isn't pretty though and it would seem much nicer if I could have something like class A<T> { event EventHandler e; } class Aadapter<T1, T2> : A<T1> { event *e; A<T2> a; Aadapter(A<T2> _a) { a = _a; e = a.e; } } in a sense we have a pointer to the event that we can assign a2's event to. I doubt there is any simple way but maybe someone has some idea to make it work. (BTW, I realize this is possible with virtual events but I'd like to avoid this if at all possible)

  • Can this PHP function be improved?

    - by jasondavis
    Below is some code I am working on for a navigation menu, if you are on a certain page, it will add a "current" css class to the proper tab. I am curious if there is a better way to do this in PHP because it really seems like a lot of code to do such a simple task? My pages will also have a jquery library already loaded, would it be better to set the tab with jquery instead of PHP? Any tips appreciated <?PHP active_header('page identifier goes here'); //ie; 'home' or 'users.online' function active_header($page_name) { // arrays for header menu selector $header_home = array('home' => true); $header_users = array( 'users.online' => true, 'users.online.male' => true, 'users.online.female' => true, 'users.online.friends' => true, 'users.location' => true, 'users.featured' => true, 'users.new' => true, 'users.browse' => true, 'users.search' => true, 'users.staff' => true ); $header_forum = array('forum' => true); $header_more = array( 'widgets' => true, 'news' => true, 'promote' => true, 'development' => true, 'bookmarks' => true, 'about' => true ); $header_money = array( 'account.money' => true, 'account.store' => true, 'account.lottery' => true, 'users.top.money' => true ); $header_account = array('account' => true); $header_mail = array( 'mail.inbox' => true, 'mail.sentbox' => true, 'mail.trash' => true, 'bulletins.post' => true, 'bulletins.my' => true, 'bulletins' => true ); // set variables if there array value exist if (isset($header_home[$page_name])){ $current_home = 'current'; }else if (isset($header_users[$page_name])){ $current_users = 'current'; }else if (isset($header_forum[$page_name])){ $current_forum = 'current'; }else if (isset($header_more[$page_name])){ $current_more = 'current'; }else if (isset($header_money[$page_name])){ $current_money = 'current'; }else if (isset($header_account[$page_name])){ $current_account = 'current'; }else if (isset($header_mail[$page_name])){ $current_mail = 'current'; } // show the links echo '<li class="' .

  • Why does the VS2005 debugger not report "base." values properly? (was "Why is this if statement fail

    - by Rawling
    I'm working on an existing class that is two steps derived from System.Windows.Forms.Combo box. The class overrides the Text property thus: public override string Text { get { return this.AccessibilityObject.Value; } set { if (base.Text != value) { base.Text = value; } } } The reason given for that "get" is this MS bug: http://support.microsoft.com/kb/814346 However, I'm more interested in the fact that the "if" doesn't work. There are times where "base.Text != value" is true and yet pressing F10 steps straight to the closing } of the "set" and the Text property is not changed. I've seen this both by just checking values in the debugger, and putting a conditional breakpoint on that only breaks when the "if" statement's predicate is true. How on earth can "if" go wrong? The class between this and ComboBox doesn't touch the Text property. The bug above shouldn't really be affecting anything - it says it's fixed in VS2005. Is the debugger showing different values than the program itself sees? Update I think I've found what is happening here. The debugger is reporting value incorrectly (including evaluating conditional breakpoints incorrectly). To see this, try the following pair of classes: class MyBase { virtual public string Text { get { return "BaseText"; } } } class MyDerived : MyBase { public override string Text { get { string test = base.Text; return "DerivedText"; } } } Put a breakpoint on the last return statement, then run the code and access that property. In my VS2005, hovering over base.Text gives the value "DerivedText", but the variable test has been correctly set to "BaseText". So, new question: why does the debugger not handle base properly, and how can I get it to?

  • C#: Determine Type for (De-)Serialization

    - by dbemerlin
    Hi, i have a little problem implementing some serialization/deserialization logic. I have several classes that each take a different type of Request object, all implementing a common interface and inheriting from a default implementation: This is how i think it should be: Requests interface IRequest { public String Action {get;set;} } class DefaultRequest : IRequest { public String Action {get;set;} } class LoginRequest : DefaultRequest { public String User {get;set;} public String Pass {get;set;} } Handlers interface IHandler<T> { public Type GetRequestType(); public IResponse HandleRequest(IModel model, T request); } class DefaultHandler<T> : IHandler<T> // Used as fallback if the handler cannot be determined { public Type GetRequestType() { return /* ....... how to get the Type of T? ((new T()).GetType()) ? .......... */ } public IResponse HandleRequest(IModel model, T request) { /* ... */ } } class LoginHandler : DefaultHandler<LoginRequest> { public IResponse HandleRequest(IModel mode, LoginRequest request) { } } Calling class Controller { public ProcessRequest(String action, String serializedRequest) { IHandler handler = GetHandlerForAction(action); IRequest request = serializer.Deserialize<handler.GetRequestType()>(serializedRequest); handler(this.Model, request); } } Is what i think of even possible? My current Solution is that each handler gets the serialized String and is itself responsible for deserialization. This is not a good solution as it contains duplicate code, the beginning of each HandleRequest method looks the same (FooRequest request = Deserialize(serializedRequest); + try/catch and other Error Handling on failed deserialization). Embedding type information into the serialized Data is not possible and not intended. Thanks for any Hints.

  • Simultaneous private and public inheritance in C++

    - by gspr
    Suppose a class Y publicly inherits a class X. Is it possible for a class Z to privately inherit Y while publicly inheriting X? To make this clearer, suppose X defines public methods x1 and x2. Y inherits X, overrides x1 and provides a method y. Does C++ allow for a third class Z to subclass Y in such a way that Y's implementation of x1 and y are privately available to it, while the outside world only sees it inheriting X publicly, i.e. having only a single public method x2?

  • Is there a way to deserialize an object into "$this"?

    - by Andreas Bonini
    I'm writing a class to handle a memcached object. The idea was to create abstract class Cachable and all the cachable objects (such as User, Post, etc) would be subclasses of said class. The class offers some method such as Load() which calls the abstract function LoadFromDB() if the object is not cached, functions to refresh/invalidate the cache, etc. The main problem is in Load(); I wanted to do something similar: protected function Load($id) { $this->memcacheId = $id; $this->Connect(); $cached = $this->memcache->get(get_class($this) . ':' . $id); if($cached === false) { $this->SetLoaded(LoadFromDB($id)); UpdateCache(); } else { $this = $cached; $this->SetLoaded(true); } } Unfortunately I need $this to become $cached (the cached object); is there any way to do that? Was the "every cachable object derives from the cachable class" a bad design idea?

  • Do I always need to rebuild the project containing references to sub project's dll, if sub projects

    - by Puneet Dudeja
    I have a solution containing 4 class library projects and one "web site" project. The web site project contains references to the 3 class library projects, whenever I make changes in any of the class library projects, the only option I see is to rebuild the web site which takes a lot of time. Is there any option that I can only update the dll references and the changes are reflected in the web site project ?

  • Copy values from one object to another.

    - by BrokeMyLegBiking
    Anyone have a suggestion for a good utility class that maps values from one object to another? I want a utility class that uses reflection and takes two objects and copies values from the 1st object to the second if there is a public property with the same name. I have two entities that are generated from a web service proxy, so I can't change the parent class or impliment an interface or anything like that. But I know that the two objects have the same public properties.
