  • ActiveRecord/sqlite3 column type lost in table view?

    - by duncan
    I have the following ActiveRecord testcase that mimics my problem. I have a People table with one attribute being a date. I create a view over that table adding one column which is just that date plus 20 minutes: #!/usr/bin/env ruby %w|pp rubygems active_record irb active_support date|.each {|lib| require lib} ActiveRecord::Base.establish_connection( :adapter => "sqlite3", :database => "test.db" ) ActiveRecord::Schema.define do create_table :people, :force => true do |t| t.column :name, :string t.column :born_at, :datetime end execute "create view clowns as select p.name, p.born_at, datetime(p.born_at, '+' || '20' || ' minutes') as twenty_after_born_at from people p;" end class Person < ActiveRecord::Base validates_presence_of :name end class Clown < ActiveRecord::Base end Person.create(:name => "John", :born_at => DateTime.now) pp Person.all.first.born_at.class pp Clown.all.first.born_at.class pp Clown.all.first.twenty_after_born_at.class The problem is, the output is Time Time String When I expect the new datetime attribute of the view to be also a Time or DateTime in the ruby world. Any ideas? I also tried: create view clowns as select p.name, p.born_at, CAST(datetime(p.born_at, '+' || '20' || ' minutes') as datetime) as twenty_after_born_at from people p; With the same result.

  • Why is Delphi unable to infer the type for a parameter TEnumerable<T>?

    - by deepc
    Consider the following declaration of a generic utility class in Delphi 2010: TEnumerableUtils = class public class function InferenceTest<T>(Param: T): T; class function Count<T>(Enumerable: TEnumerable<T>): Integer; overload; class function Count<T>(Enumerable: TEnumerable<T>; Filter: TPredicate<T>): Integer; overload; end; Somehow the compiler type inference seems to have problems here: var I: Integer; L: TList<Integer>; begin TEnumerableUtils.InferenceTest(I); // no problem here TEnumerableUtils.Count(L); // does not compile: E2250 There is no overloaded version of 'Count' that can be called with these arguments TEnumerableUtils.Count<Integer>(L); // compiles fine end; The first call works as expected and T is correctly inferred as Integer. The second call does not work, unless I also add <Integer -- then it works, as can be seen in the third call. Am I doing something wrong or is the type inference in Delphi just not supporting this (I don't think it is a problem in Java which is why expected it to work in Delphi, too).

  • Java inheritance and super() isn't working as expected

    - by dwwilson66
    For a homework assignment, I'm working with the following. It's an assigned class structure, I know it's not the best design by a long shot. Class | Extends | Variables -------------------------------------------------------- Person | None | firstName, lastName, streetAddress, zipCode, phone CollegeEmployee | Person | ssn, salary,deptName Faculty | CollegeEmployee | tenure(boolean) Student | person | GPA,major So in the Faculty class... public class Faculty extends CollegeEmployee { protected String booleanFlag; protected boolean tenured; public Faculty(String firstName, String lastName, String streetAddress, String zipCode, String phoneNumber,String ssn, String department,double salary) { super(firstName,lastName,streetAddress,zipCode,phoneNumber, ssn,department,salary); String booleanFlag = JOptionPane.showInputDialog (null, "Tenured (Y/N)?"); if(booleanFlag.equals("Y")) tenured = true; else tenured = false; } } It was my understanding that super() in Faculty would allow access to the variables in CollegeEmployee as well as Person. With the code above, it compiles fine when I ONLY include the Person variables. As soon as I try to use ssn, department, or salary I get the following compile errors. Faculty.java:15: error: constructor CollegeEmployee in class CollegeEmployee can not be applied to the given types: super(firstName,lastName,streetAddress,zipCode,phoneNumber,ssn,department,salary); ^ Required: String,String,String,String,String Found: String,String,String,String,String,String,String,String reason: actual and formal argument lists differ in length I'm completely confused by this error...which is the actual and formal? Person has five arguments, CollegeEmployee has 3, so my guess is that something's funky with how the parameters are being passed...but I'm not quite sure where to begin fixing it. What am I missing?

  • wxPthon problems with Wrapping StaticText

    - by Scott B
    Hello. I am having an issue with wxPython. A simplified version of the code is posted below (white space, comments, etc removed to reduce size - but the general format to my program is kept roughly the same). When I run the script, the static text correctly wraps as it should, but the other items in the panel do not move down (they act as if the statictext is only one line and thus not everything is visible). If I manually resize the window/frame, even just a tiny amount, everything gets corrected and displays as it is should. I took screen shots to show this behavior, but I just created this account and thus don't have the required 10 reputation points to be allowed to post pictures. Why does it not display correctly to begin with? I've tried all sorts of combination's of GetParent().Refresh() or Update() and GetTopLevelParent().Update() or Refresh(). I've tried everything I can think of but cannot get it to display correctly without manually resizing the frame/window. Once re-sized, it works exactly as I want it to. Information: Windows XP Python 2.5.2 wxPython 2.8.11.0 (msw-unicode) Any suggestions? Thanks! Code: #! /usr/bin/python import wx class StaticWrapText(wx.PyControl): def __init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, validator=wx.DefaultValidator, name='StaticWrapText'): wx.PyControl.__init__(self, parent, id, pos, size, style, validator, name) self.statictext = wx.StaticText(self, wx.ID_ANY, label, style=style) self.wraplabel = label #self.wrap() def wrap(self): self.Freeze() self.statictext.SetLabel(self.wraplabel) self.statictext.Wrap(self.GetSize().width) self.Thaw() def DoGetBestSize(self): self.wrap() #print self.statictext.GetSize() self.SetSize(self.statictext.GetSize()) return self.GetSize() class TestPanel(wx.Panel): def __init__(self, *args, **kwargs): # Init the base class wx.Panel.__init__(self, *args, **kwargs) self.createControls() def createControls(self): # --- Panel2 ------------------------------------------------------------- self.Panel2 = wx.Panel(self, -1) msg1 = 'Below is a List of Files to be Processed' staticBox = wx.StaticBox(self.Panel2, label=msg1) Panel2_box1_v1 = wx.StaticBoxSizer(staticBox, wx.VERTICAL) Panel2_box2_h1 = wx.BoxSizer(wx.HORIZONTAL) Panel2_box3_v1 = wx.BoxSizer(wx.VERTICAL) self.wxL_Inputs = wx.ListBox(self.Panel2, wx.ID_ANY, style=wx.LB_EXTENDED) sz = dict(size=(120,-1)) wxB_AddFile = wx.Button(self.Panel2, label='Add File', **sz) wxB_DeleteFile = wx.Button(self.Panel2, label='Delete Selected', **sz) wxB_ClearFiles = wx.Button(self.Panel2, label='Clear All', **sz) Panel2_box3_v1.Add(wxB_AddFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_DeleteFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_ClearFiles, 0, wx.TOP, 0) Panel2_box2_h1.Add(self.wxL_Inputs, 1, wx.ALL|wx.EXPAND, 2) Panel2_box2_h1.Add(Panel2_box3_v1, 0, wx.ALL|wx.EXPAND, 2) msg = 'This is a long line of text used to test the autowrapping ' msg += 'static text message.

  • PHP: OOP and methods

    - by Pirkka
    Hello I`ve been wondering how to implement methods in a class. Could someone explain me what means if one does OOP in procedural style? Here is an example: class Fld extends Model { private $file; private $properties = array(); public function init($file) { $this->file = $file; $this->parseFile(); } private function parseFile() { // parses the file foreach($this->file as $line)...... .................. $this->properties = $result; } } I mean is it a good thing to have methods like these that do operations for the class properties like that. Or should I pass the class property as method parameter... I mean this would cause error if the file property wouldnt be declared.

  • No improvement in speed when using Ehcache with Hibernate

    - by paddydub
    I'm getting no improvement in speed when using Ehcache with Hibernate Here are the results I get when i run the test below. The test is reading 80 Stop objects and then the same 80 Stop objects again using the cache. On the second read it is hitting the cache, but there is no improvement in speed.

  • I get a 400 Bad Request error while using django-piston

    - by Cheezo
    Hello, I am trying to use Piston to provide REST support to Django. I have implemented my handlers as per the documentation provided . The problem is that i can "read" and "delete" my resource but i cannot "create" or "update". Each time i hit the relevant api i get a 400 Bad request Error. I have extended the Resource class for csrf by using this commonly available code snippet: class CsrfExemptResource(Resource): """A Custom Resource that is csrf exempt""" def init(self, handler, authentication=None): super(CsrfExemptResource, self).init(handler, authentication) self.csrf_exempt = getattr(self.handler, 'csrf_exempt', True) My class (code snippet) looks like this: user_resource = CsrfExemptResource(User) class User(BaseHandler): allowed_methods = ('GET', 'POST', 'PUT', 'DELETE') @require_extended def create(self, request): email = request.GET['email'] password = request.GET['password'] phoneNumber = request.GET['phoneNumber'] firstName = request.GET['firstName'] lastName = request.GET['lastName'] self.createNewUser(self, email,password,phoneNumber,firstName,lastName) return rc.CREATED Please let me know how can i get the create method to work using the POST operation?

  • How to Declare Complex Nested C# Type for Web Service

    - by TheArtTrooper
    I would like to create a service that accepts a complex nested type. In a sample asmx file I created: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class ServiceNest : System.Web.Services.WebService { public class Block { [XmlElement(IsNullable = false)] public int number; } public class Cell { [XmlElement(IsNullable = false)] public Block block; } public class Head { [XmlElement(IsNullable = false)] public Cell cell; } public class Nest { public Head head; } [WebMethod] public void TakeNest(Nest nest) { } } When I view the asmx file in IE the test page shows the example SOAP post request as: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <TakeNest xmlns="http://schemas.intellicorp.com/livecompare/"> <nest> <head> <cell> <block xsi:nil="true" /> </cell> </head> </nest> </TakeNest> </soap:Body> </soap:Envelope> It hasn't expanded the <block> into its number member. Looking at the WSDL, the types all look good. So is this just a limitation of the post demo page creator? Thanks.

  • Is it possible to convert this asp to asp.net?

    - by Phil
    I have been tasked with sifting through the worst classic asp spaghetti i've ever come across. The script runs a series of recordsets in sequence, getting 1 record at a time. As the record is built it takes the id and passes it to the next loop, which gets data, and passes on the id to the next loop. It then continues in this manner and builds an unordered list, kicking out the required html as it goes. Here are my efforts so far: have a class delivering data via sqldatareaders and output these to nested repeaters (this failed due to not being able to loop and get the id) Have a datatable populated with all the required data, then datatable.select to filter it out. have 4 datareaders looping and building the ul arraylists (I couldnt get the id's to match up) Please can you suggest the best method (with a bit of sample code if possible) to go about doing this conversion? Here is the code (sorry its long / horrible / spaghetti!!!) <% set RSMenuLevel0 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = 0 and Publish <> 0) order by OrderID") %> <% if session("JavaScriptEnabled") = "False" Then %> <% while not RSMenuLevel0.EOF if RSMenuLevel0("Publish") <> 0 then Menu0heading = RSMenuLevel0("Heading") Menu0id = RSMenuLevel0("id") %> <%if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then%> &nbsp;<a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>"><%=Menu0heading%></a> <%else%> &nbsp;<a href="/default.asp?id=<%=Menu0id%>"><%=Menu0heading%></a> <%end if%> <% end if RSMenuLevel0.MoveNext wend %> <% else %> <ul id="Menu1" class="MM"> <%if home <> 1 then%> <!-- <li><a href="/default.asp"><span class="item">Home</span></a> --> <%end if%> <% numone=0 while not RSMenuLevel0.EOF ' numone = numone + 1 Menu0heading = RSMenuLevel0("Heading") 'itemID = lcase(replace(Menu0heading," ","")) Menu0id = RSMenuLevel0("id") if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then url = RSMenuLevel0("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%else%> <li><a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel0("id")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <% set RSMenuLevel1 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu0id & " and Publish <> 0) order by OrderID") if not RSMenuLevel1.EOF then %> <ul> <% while not RSMenuLevel1.EOF Menu1heading = RSMenuLevel1("Heading") Menu1id = RSMenuLevel1("id") if RSMenuLevel1("url") > "" and RSMenuLevel1("moduleid") = 0 then url = RSMenuLevel1("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%else%> <li><a href="http://<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel1("id")%>"><%=Menu1heading%></a> <%end if%> <% set RSMenuLevel2 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu1id & " and Publish <> 0) order by OrderID") if not RSMenuLevel2.EOF then %> <ul> <% while not RSMenuLevel2.EOF Menu2heading = RSMenuLevel2("Heading") Menu2id = RSMenuLevel2("id") if RSMenuLevel2("url") > "" and RSMenuLevel2("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel2("url")%>" target="<%=RSMenuLevel2("urltarget")%>"><%=Menu2heading%></a> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel2("id")%>"><%=Menu2heading%></a> <%end if%> <% set RSMenuLevel3 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu2id & " and Publish <> 0) order by OrderID") if not RSMenuLevel3.EOF then %> <ul> <% while not RSMenuLevel3.EOF Menu3heading = RSMenuLevel3("Heading") Menu3id = RSMenuLevel3("id") if RSMenuLevel3("url") > "" and RSMenuLevel3("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel3("url")%>" target="<%=RSMenuLevel3("urltarget")%>"><%=Menu3heading%></a></li> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel3("id")%>"><%=Menu3heading%></a></li> <%end if%> <% RSMenuLevel3.MoveNext wend %> </ul> <% end if RSMenuLevel2.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel1.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel0.MoveNext %> </li> <% wend %> </ul> <% end if %>

  • Java Package - To create a button and import one when needed.

    - by Zopyrus
    This is more like a package/import test. We'll start with my base folder at .../javaf/test.java My goal is to create subcategory and create a class with a button that I can import to test.java when I need a button. I feel like I've done it right, I know that the button doesn't do anything as of now, but I just want to make the whole thing work and expand the code thereafter. So here goes - This is test.java import paket.*; // importing classes from subcategory paket! import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.util.*; public class test { public test() { JFrame myFrame; JPanel myPanel; myFrame = new JFrame("Hello FramWorld"); myPanel = new JPanel(); // Here I want to add the object created in paket/myButts.java // The problem is how to make these two lines work. myButts myButton = new myButts(); myPanel.add(myButton); myFrame.setVisible(true); myFrame.getContentPane().add(myPanel, BorderLayout.CENTER); myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myFrame.pack(); } public static void main(String args[]) { new test(); } } And here is my .../javaf/paket/myButts.java package paket; // Here is the package function (ought to work like a link) import javax.swing.*; import java.awt.*; import java.awt.event.*; // This class should only create a button. public class myButts { public myButts() { JButton myButt = new JButton(); } } I've compiled myButts.java with no errors. But then I compile test.java and it gives me the following error: test.java:19: cannot find symbol symbol : method add(paket.myButts) location: class javax.swing.JPanel myPanel.add(myButton); Thanks for reading, Z

  • Singleton Pattern for C#

    - by cam
    I need to store a bunch of variables that need to be accessed globally and I'm wondering if a singleton pattern would be applicable. From the examples I've seen, a singleton pattern is just a static class that can't be inherited. But the examples I've seen are overly complex for my needs. What would be the very simplest singleton class? Couldn't I just make a static, sealed class with some variables inside?

  • Problems finding classes in namespace and testing extend expected parent

    - by Matt
    So I am in the process of building a site in ASP.Net MVC, and in the process I am adding certain things to my Site.Master I want to make sure that all of my model classes extend a certain base class that contains all of the pieces the Site.Master needs to be operable. I want to test to make sure this assumption isn't broken (I believe this will save me time when I forget about it and can't figure out why a new combination isn't working.) I wrote a test that I thought would help with this, but I am running into two problems. First it isn't finding the one example model class I have so far in the LINQ call all of a sudden, I am admittedly still a bit new to LINQ. Second, I had it finding the class earlier, but I couldn't get it to verify that the class inherits from the base class. Here is the example test. [Test] public void AllModelClassesExtendAbstractViewModel() { var abstractViewModelType = typeof (AbstractViewModel); Assembly baseAssembly = Assembly.GetAssembly(abstractViewModelType); var modelTypes = baseAssembly.GetTypes() .Where(assemblyType => (assemblyType.Namespace.EndsWith("Models") && assemblyType.Name != "AbstractViewModel")) .Select(assemblyType => assemblyType); foreach (var modelType in modelTypes) { Assert.That(modelType.IsSubclassOf(abstractViewModelType), Is.True , modelType.Name + " does not extend AbstractViewModel"); } }

  • [C++] Multiple inclusion in multiple files

    - by Amumu
    Hi everyone, I am making a small game. In BattleRecord.h: #ifndef _CHARACTER_H_ #define _CHARACTER_H_ #include "Character.h" #endif class BattleRecord { public: Character Attacker; Character Defender; Status status; int DamageDealt; int GoldEarned; int ExpGained; }; In Character.h: #ifndef _EQUIPMENT_H_ #define _EQUIPMENT_H_ #include "Equipment.h" #endif class BattleRecord; class Character { BattleRecord AttackEnemy(Character &Enemy); } In BattleRecord.h: #ifndef _CHARACTER_H_ #define _CHARACTEr_H_ #include "Character.h" #endif #ifndef _BATLE_RECORD_H_ #define _BATLE_RECORD_H_ #include "BattleRecord.h" #endif class GUI { public: //GUI Methods, and two of these: void ViewStats(Character &Player); void Report(BattleRecord Record) } The problem here is, my Character.h and BattleRecord.h need to include each other, and this definitely will cause multiple redefinition problem. Therefore, I used forward declaration in Character.h by adding: class BattleRecord; The problem is sovled. But then, the GUI.h needs BattleRecord.h again for reporting the battle, so I have to include BattleRecord.h into the GUI.h. I also have to include the Character.h in order to pass into the ViewStat function. I got error and stuck with this up to this piont.

  • Java - How to declare table[i][j] elements as instance variables?

    - by JDelage
    All, I am trying to code a Connect4 game. For this, I have created a P4Game class and a P4Board class which represents the i X j dimensions of the Connect4 board. In P4Game, I have the following: public class P4Game{ //INSTANCE VARIABLES private int nbLines; private int nbColumns; private P4Board [][] position; //CONSTRUCTOR public P4Game(int nbLines, int nbColumns){ this.nbColumns = nbColumns; this.nbLines = nbLines; P4Board [][] position = new P4Board [nbLines][nbColumns]; //Creates the table to receive the instances of the P4Board object.*/ for (int i=0; i<nbLines; i++){ for (int j=0; j<nbColumns; j++){ this.position[i][j] = new P4Board(i,j); //Meant to create each object at (line=i, column=j) } } } This causes a NullPointerException in the nested loops where I mention this.position[i][j]. I reference those objects in other methods of this class so I need them to be instance variables. I suppose the exception is due to the fact that I have not listed the table element position[i][j] as an instance variable at the beginning of the class. my question to people here is (1) is my assumption correct, and if so (2) what would be the syntax to declare instance variables of this form? Thank you all for your help with what I realize is a very basic question. Hopefully it will also benefit other newbies. Cheers, JDelage

  • .Net lambda expression-- where did this parameter come from?

    - by larryq
    I'm a lambda newbie, so if I'm missing vital information in my description please tell me. I'll keep the example as simple as possible. I'm going over someone else's code and they have one class inheriting from another. Here's the derived class first, along with the lambda expression I'm having trouble understanding: class SampleViewModel : ViewModelBase { private ICustomerStorage storage = ModelFactory<ICustomerStorage>.Create(); public ICustomer CurrentCustomer { get { return (ICustomer)GetValue(CurrentCustomerProperty); } set { SetValue(CurrentCustomerProperty, value); } } private int quantitySaved; public int QuantitySaved { get { return quantitySaved; } set { if (quantitySaved != value) { quantitySaved = value; NotifyPropertyChanged(p => QuantitySaved); //where does 'p' come from? } } } public static readonly DependencyProperty CurrentCustomerProperty; static SampleViewModel() { CurrentCustomerProperty = DependencyProperty.Register("CurrentCustomer", typeof(ICustomer), typeof(SampleViewModel), new UIPropertyMetadata(ModelFactory<ICustomer>.Create())); } //more method definitions follow.. Note the call to NotifyPropertyChanged(p => QuantitySaved) bit above. I don't understand where the "p" is coming from. Here's the base class: public abstract class ViewModelBase : DependencyObject, INotifyPropertyChanged, IXtremeMvvmViewModel { public event PropertyChangedEventHandler PropertyChanged; protected virtual void NotifyPropertyChanged<T>(Expression<Func<ViewModelBase, T>> property) { MvvmHelper.NotifyPropertyChanged(property, PropertyChanged); } } There's a lot in there that's not germane to the question I'm sure, but I wanted to err on the side of inclusiveness. The problem is, I don't understand where the 'p' parameter is coming from, and how the compiler knows to (evidently?) fill in a type value of ViewModelBase from thin air? For fun I changed the code from 'p' to 'this', since SampleViewModel inherits from ViewModelBase, but I was met with a series of compiler errors, the first one of which statedInvalid expression term '=>' This confused me a bit since I thought that would work. Can anyone explain what's happening here?

  • Is there a pattern that allows a constructor to be called only from a specific factory and from nowh

    - by willem
    We have a class, say LegacyUserSettingsService. LegacyUserSettingsService implements an interface, IUserSettingsService. You can get an instance of the IUserSettingsService by calling our ApplicationServicesFactory. The factory uses Spring.NET to construct the concrete LegacyUserSettingsService. The trouble is that new developers sometimes do their own thing and construct new instances of the LegacyUserSettingsService directly (instead of going via the factory). Is there a way to protect the constructor of the concrete class so it can only be called from the factory? A well-known pattern perhaps? Note that the concrete class resides in a different assembly (separate from the Factory's assembly, so the internal keyword is not a solution). The factory assembly references the other assembly that contains the concrete class. Any ideas?
