  • How to order my objects in a C++ class correctly

    - by Julen
    Hello, I have been coding regurlarly in C++ in the past months. I am getting used to it step by step... but there are things that confuse me about formatting. I know there is a lot of legacy from C that I supousee mixes with C++. This time I have doubts about how to order properly my members and functions within in a class. Also considering their access modifiers. How is the convention in this? Until know I am doing everything "public" and writing first constructor of class, then destructor, next members and finally functions. It this correct? What happens when introducing "private" and "protected" access modifiers or "virtual" functions? From the documents I have look in the Internet there is different ways of doing things. But my questions aims to get the knowledge from a community that develops in C++ that I want to blend into. ;-) Thanks a lot!!!

  • Design pattern: Polymorphism for list of objects

    - by ziang
    Suppose I have a class A, and A1, A2 inherits from A. There are 2 functions: List<A1> getListA1(){...} List<A2> getListA2(){...} Now I want to do something similar to both A1 and A2 in another function public void process(List<A>){...} If I want to pass the instance of either ListA1 or ListA2, of course the types doesn't match because the compiler doesn't allow the coercion from List< A1 to List< A. I can't do something like this: List<A1> listA1 = getListA1(); List<A> newList = (List<A>)listA1; //this is not allowed. So what is the best approach to the process()? Is there any way to do it in a universal way rather than write the similar code to both List and List?

  • Can I use MFC objects in STL containers?

    - by Jesse Stimpson
    The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

  • Using AJAX to return SelectList selected value

    - by Adventure
    At risk of asking the obvious... I need to use AJax.ActionLink to send the current value of a SelectList back to my controller. How do I do that? Below is part of my current View. I need to replace "15" with the current value of the SelectList. <% If Model.ShoppingListNames IsNot Nothing Then%> <%: Html.DropDownList("ShoppingListNames", Model.ShoppingListNames)%> <%: Ajax.ActionLink("Add to List", "AdjustMaterials", "Docs", New With {.userDocId = 15, .prodId = Model.ID, .quantity = 1}, New AjaxOptions With {.OnSuccess = "handleUpdate"})%> <% End If%>

  • php: two objects from the same class work independent of each other

    - by user317563
    Good morning, I would like the code in my controller to look something like this: <?php $class = new sanitizeInput() $string1 = $class -> input($_POST[name]) -> mysql_escape(); $string2 = $class -> input($_POST[age]) -> mysql_escape(); print " String1: $string1 <br /> String2: $string2" ?> It seems with my sanitizeInput class, any change to $string2 is applied to $string1. What ways can I change this? I would preferably like to make the changes within the class to make my controller as easily read as possible. Thank you for your time. Kind regards, Marius

  • C# Using Reflection to Get a Generic Object's (and its Nested Objects) Properties

    - by Jimbo
    This is a scenario created to help understand what Im trying to achieve. I am trying to create a method that returns the specified property of a generic object e.g. public object getValue<TModel>(TModel item, string propertyName) where TModel : class{ PropertyInfo p = typeof(TModel).GetProperty(propertyName); return p.GetValue(item, null); } The code above works fine if you're looking for a property on the TModel item e.g. string customerName = getValue<Customer>(customer, "name"); However, if you want to find out what the customer's group's name is, it becomes a problem: e.g. string customerGroupName = getValue<Customer>(customer, "Group.name"); Hoping someone can give me some insight on this way out scenario - thanks.

  • The Relationship Between Activities and View Objects - Android

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

  • Creating objects and referencing before saving object to db

    - by Flexo
    Sorry about the vague title, but i didnt know how to ask the question in one line :) I have an order with nested itemgroups that again have nested items. the user specify the amount of item that he would like to have in each itemgroup. I would like to create these items in the create method of the orders controller when the order itself is being created. I kinda have 2 problems here. First, how do i set the reference of the items, or better yet, put the items into the @order object so they are saved when the @order is saved? the items are being stored in the db as the code is now, but the reference is not set because the order is not stored in the db yet so it doesnt have an id yet. Second, im not sure im using the correct way to get the id from my itemgroup. @order = Order.new(params[:order]) @order.itemgroups.each do |f| f.amount.times do @item = Item.new() @item.itemgroup_id = f.id @item.save end end

  • Static selection and Ruby on Rails objects

    - by Dave
    Hi all- I have a simple problem, but am having trouble wrapping my head around it. I have an video object that should have one or more "genres". This list of genres should be prepopulated and then the user should just select one or more using autocomplete or some such. Here is the question: Is it worth creating a table with genres for the static selection? Or should it just be included in the presentation layer? If there is a static table, how do we name it correctly. I envision something like this class Video < ActiveRecord::Base has_many :genres ... end class Genre < ... belongs_to :video ... end But then we get a table called genre, that basically maps all the selected genres to their parent videos. There would need to be some static table to reference the static genres. Is this the best way to do it? Sorry if this was rambl-y a little stream of conciousness. Thanks!

  • Rails - using :include to find objects based on their child's attributes

    - by adam
    I have a sentence and correction model class Sentence < ActiveRecord::Base has_one :correction class Correction < ActiveRecord::Base belongs_to :sentence and I'm trying find all sentences which don't have a correction. To do this I'm simply looking for corrections which don't exist i.e. whose id = nil. But it is failing and i can't figure out why Sentence.find :all, :include => :correction, :conditions => {:correction => {:id => nil}} Perhaps its the syntax or maybe just the overall approach. Can anyone help?

  • Pass form object value to static method

    - by jrubengb
    Hi, I need to take a form object value and pass it into a static method: public void SetCalendarStartSafe(DateTime startDateSafe) { startDateSafe = calendarStart.Value; } private static DataTable GetData() { frmMain frm = new frmMain(); DateTime startDate = new frmMain(); frm.SetCalendarStartSafe(startDate); } However I keep getting today's current date whenever I try this approach, even if the specified calendar date on the form is different. How can I can the user-specified calendar date from the original frmMain object? Thanks in advance for any guidance.

  • Returning objects with dynamic memory

    - by Caulibrot
    I'm having trouble figuring out a way to return an object (declared locally within the function) which has dynamic memory attached to it. The problem is the destructor, which runs and deletes the dynamic memory when the object goes out of scope, i.e. when I return it and want to use the data in the memory that has been deleted! I'm doing this for an overloaded addition operator. I'm trying to do something like: MyObj operator+( const MyObj& x, const MyObj& y ) { MyObj z; // code to add x and y and store in dynamic memory of z return z; } My destructor is simply: MyObj::~MyObj() { delete [] ptr; } Any suggestions would be much appreciated!

  • Fastest way to compare Objects of type DateTime

    - by radbyx
    I made this. Is this the fastest way to find lastest DateTime of my collection of DateTimes? I'm wondering if there is a method for what i'm doing inside the foreach, but even if there is, I can't see how it can be faster than what i all ready got. List<StateLog> stateLogs = db.StateLog.Where(p => p.ProductID == product.ProductID).ToList(); DateTime lastTimeStamp = DateTime.MinValue; foreach (var stateLog in stateLogs) { int result = DateTime.Compare(lastTimeStamp, stateLog.TimeStamp); if (result < 0) lastTimeStamp = stateLog.TimeStamp; // sæt fordi timestamp er senere }

  • jQuery and array of objects

    - by sepoto
    $(document).ready(function () { output = ""; $.ajax({ url: 'getevents.php', data: { ufirstname: 'ufirstname' }, type: 'post', success: function (output) { alert(output); var date = new Date(); var d = date.getDate(); var m = date.getMonth(); var y = date.getFullYear(); $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,basicWeek,basicDay' }, editable: true, events: output }); } }); }); I have code like this and if I copy the text verbatim out of my alert box and replace events: output with events: [{ id: 1, title: 'Birthday', start: new Date(1355011200*1000), end: new Date(1355011200*1000), allDay: true, url: 'http://www.yahoo.com/'},{ id: 2, title: 'Birthday Hangover', start: new Date(1355097600*1000), end: new Date(1355097600*1000), allDay: false, url: 'http://www.yahoo.com'},{ id: 3, title: 'Sepotomus Maximus Christmas', start: new Date(1356393600*1000), end: new Date(1356393600*1000), allDay: false, url: 'http://www.yahoo.com/'},] Everything works just fine. What can I do to fix this problem? I though that using events: output would place the text in that location but it does not seem to be working. Thank you all kindly in advance for any comments or answers!

  • How to select all ActiveX objects in an area using a mouse in Excel?

    - by enderland
    Because of this problem with ActiveX objects changing size, I am not grouping my ActiveX objects in my Excel worksheet. Grouping them causes my solution hack to not work which is quite annoying. However, I often times want to be able to essentially use the mouse and select a region and then select all ActiveX objects contained in the region. This would also be useful for easily selecting objects to group them initially. Basically: Use mouse to select area Automatically select all ActiveX components in region I'm fine with a VBA solution if needed. How can I do this?

  • JSP::Confused with the session objects

    - by Legend
    I just started exploring Java Servlets and JSP and am a little confused about the sessions object. Inside a servlet I have this: public class SampleServlet extends HttpServlet { public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException { HttpSession session = request.getSession(true); session.setAttribute("_session", "_value"); response.sendRedirect("page2.jsp"); } } Now, inside page2.jsp, there is a session object as well, but when I do this <% out.print(session.getAttribute("_session")) %> it gives me an error. Can someone tell me the right way of doing this? As to what I am trying to do, I want to share some session variables.

  • SubSonic Change DropDown Value for Load Drops SUB

    - by GTJR
    I used the subsonic generator to create some aspx pages, It works fine. On some of the pages it automaticaly generated the dropdown boxes for foreign key values. How Can change that value in the load drops code? Or where I need to change it. For instance I have a workers table and a workersweek table. The workers table has a workerid,firstname and lastname field and the workersweek has a workerID field. The generator automatically set it up to show the firstname in the dropdown. I want to change the value to be both firstname and lastname. I am sure I will have to add code that does something like firstname + " " + Lastname. I am just not sure where to do it withing the code that was generated. I see the load drops sub, but it does not seem like that is the one I need to modify.
