• Disallow private constructor invocation in friend function

  - by user2907032

  Is there any way to not allow private construction in friend function, In case we do have private constructor with friend function in our class. Only Static method should be responsible for object creation and other than this compiler should flash error message #include <iostream> #include <memory> using namespace std; class a { public: void see () { cout<<"Motimaa"; } static a& getinstance() { static a instance; return instance; } private: a() {}; friend void access(); }; void access () { a obj; obj.see();//still friend function can access } int main() { a::getinstance().see(); access(); return 1; }

• WPF multibound textblock not updating

  - by Superstringcheese

  I want to create a program which calculates how long it will take to repeat a process a certain number of times. I've scaled this down a lot for this example. So, I have some textboxes which are bound to properties in a class: Count: <TextBox x:Name="txtCount" Text="{Binding Count, Mode=TwoWay}" Width="50"/> Days: <TextBox x:Name="txtDays" Text="{Binding Days, Mode=TwoWay}" Width="50"/> and a textblock which is multibound like so: <TextBlock x:Name="tbkTotal"> <TextBlock.Text> <MultiBinding StringFormat="Days: {0}, Count: {1}"> <Binding Path="Days" /> /* This isn't updating */ <Binding Path="Count" /> </MultiBinding> </TextBlock.Text> </TextBlock> My DataContext is set in the Window1.xaml.cs file. public Window1() { InitializeComponent(); Sample sample = new Sample(); this.DataContext = sample; } I can update the multibound textblock with the Count property just fine, but the Days property always shows 0, even though the Days input accurately reflects changes. I believe that this is because my accessors are different for Days - namely, the Set method. This class is in a different file. public class Sample : INotifyPropertyChanged { private int _count; private TimeSpan _span; public int Count { get { return _count; } set { _count = value; NotifyPropertyChanged("Count"); /* Doesn't seem to be needed, actually */ } } public TimeSpan Span { get { return _span; } } /* The idea is to provide a property for Days, Hours, Minutes, etc. as conveniences to the inputter */ public double Days { get { return _span.Days; } set { TimeSpan ts = new TimeSpan(); double val = value > 0 ? value : 0; ts = TimeSpan.FromDays(val); _span.Add(ts); NotifyPropertyChanged("Span"); /* Here I can only get it to work if I notify that Span has changed - doesn't seem to be aware that the value behind Days has changed. */ } } private void NotifyPropertyChanged(string property) { if (null != this.PropertyChanged) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } public Sample() { _count = 0; _span = new TimeSpan(); } public event PropertyChangedEventHandler PropertyChanged; }

• Stubbing a before_filter with RSpec

  - by TheDelChop

  Guys, I'm having trouble understanding why I can't seem to stub this controller method :load_user, since all of my tests fail if I change the actual implementation of :load_user to not return and instance of @user. Can anybody see why my stub (controller.stub!(:load_user).and_return(@user)) seems to fail to actually get called when RSpec makes a request to the controller? require 'spec_helper' describe TasksController do before(:each) do @user = Factory(:user) sign_in @user @task = Factory(:task) User.stub_chain(:where, :first).and_return(@user) controller.stub!(:load_user).and_return(@user) end #GET Index describe "GET Index" do before(:each) do @tasks = 7.times{Factory(:task, :user = @user)} @user.stub!(:tasks).and_return(@tasks) end it "should should find all of the tasks owned by a user" do @user.should_receive(:tasks).and_return(@tasks) get :index, :user_id = @user.id end it "should assign all of the user's tasks to the view" do get :index, :user_id = @user.id assigns[:tasks].should be(@tasks) end end #GET New describe "GET New" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should return a new Task" do @user.tasks.should_receive(:new).and_return(@task) get :new, :user_id = @user.id end end #POST Create describe "POST Create" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should create a new task" do @user.tasks.should_receive(:new).and_return(@task) post :create, :user_id = @user.id, :task = @task.to_s end it "saves the task" do @task.should_receive(:save) post :create, :user_id = @user.id, :task = @task end context "when the task is saved successfully" do before(:each) do @task.stub!(:save).and_return(true) end it "should set the flash[:notice] message to 'Task Added Successfully'"do post :create, :user_id = @user.id, :task = @task flash[:notice].should == "Task Added Successfully!" end it "should redirect to the user's task page" do post :create, :user_id = @user.id, :task = @task response.should redirect_to(user_tasks_path(@user.id)) end end context "when the task isn't saved successfully" do before(:each) do @task.stub(:save).and_return(false) end it "should return to the 'Create New Task' page do" do post :create, :user_id = @user.id, :task = @task response.should render_template('new') end end end it "should attempt to authenticate and load the user who owns the tasks" do context "when the tasks belong to the currently logged in user" do it "should set the user instance variable to the currently logged in user" do pending end end context "when the tasks belong to another user" do it "should set the flash[:notice] to 'Sorry but you can't view other people's tasks.'" do pending end it "should redirect to the home page" do pending end end end end class TasksController < ApplicationController before_filter :load_user def index @tasks = @user.tasks end def new @task = @user.tasks.new end def create @task = @user.tasks.new if @task.save flash[:notice] = "Task Added Successfully!" redirect_to user_tasks_path(@user.id) else render :action => 'new' end end private def load_user if current_user.id == params[:user_id].to_i @user = User.where(:id => params[:user_id]).first else flash[:notice] = "Sorry but you can't view other people's tasks." redirect_to root_path end end end Can anybody see why my stub doesnt' work? Like I said, my tests only pass if I make sure that load_user works, if not, all my tests fail which makes my think that RSpec isn't using the stub I created. Thanks, Joe

• Spring.Net Message Selectors with compound statements don't seem to be working

  - by Jonathan Beerhalter

  I'm using Spring.NET to connect to ActiveMQ and do some fairly simple pub sub routing. Everything works fine when my selector is a simple expression like Car='Honda' but if I try a compound expression like Car='Honda' AND Make='Pilot' I never get any matches on my subscription. Here's the code to generate the subscription, does anyone see where I might be doing something wrong? public bool AddSubscription(string topicName, Dictionary<string,string> selectorList, GDException exp) { try { ActiveMQTopic topic = new ActiveMQTopic(topicName); string selectorString = ""; if (selectorList.Keys.Count == 0) { // Select all items for this topic selectorString = "2>1"; } else { foreach (string key in selectorList.Keys) { selectorString += key + " = '" + selectorList[key] + "'" + " AND "; } selectorString = selectorString.Remove(selectorString.Length - 5, 5); } IMessageConsumer consumer = this._subSession.CreateConsumer(topic, selectorString, false); if (consumer != null) { _consumers.Add(consumer); consumer.Listener += new MessageListener(HandleRecieveMessage); return true; } else { exp.SetValues("Error adding subscription, null consumer returned"); return false; } } catch (Exception ex) { exp.SetValues(ex); return false; } } And then the code to send the message, which seems simple enough to me public void SendMessage(GDPubSubMessage messageToSend) { if (!this.isDisposed) { if (_producers.ContainsKey(messageToSend.Topic)) { IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage, false, (byte)255, TimeSpan.FromSeconds(1)); } else { ActiveMQTopic topic = new ActiveMQTopic(messageToSend.Topic); _producers.Add(messageToSend.Topic, this._pubSession.CreateProducer(topic)); IBytesMessage bytesMessage = this._pubSession.CreateBytesMessage(messageToSend.Payload); foreach (string key in messageToSend.MessageProperties.Keys) { bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); } _producers[messageToSend.Topic].Send(bytesMessage); } } else { throw new ObjectDisposedException(this.GetType().FullName); } } 07/102009: Update Ok, found the problem bytesMessage.Properties.SetString(key, messageToSend.MessageProperties[key]); This justs sets a single property, so my messages are only being tagged with a single property, hence the combo subscription never gets hit. Anyone know how to add more properties? You'd think bytesMessage.Properties would have a Add method, but it doesn't.

• F# pattern matching when mixing DU's and other values

  - by Roger Alsing

  What would be the most effective way to express the following code? match cond.EvalBool() with | true -> match body.Eval() with | :? ControlFlowModifier as e -> match e with | Break(scope) -> e :> obj //Break is a DU element of ControlFlowModifier | _ -> next() //other members of CFM should call next() | _ -> next() //all other values should call next() | false -> null cond.EvalBool returns a boolean result where false should return null and true should either run the entire block again (its wrapped in a func called next) or if the special value of break is found, then the loop should exit and return the break value. Is there any way to compress that block of code to something smaller?

  - by Enrique

  My MySQL tables structure is like this. USER int id varchar username FRIEND_LIST int user_id int friend_id For each friend relationship I insert 2 records in FRIEND_LIST. If user 1 is friend of user 2 then the next rows are inserted into FRIEND_LIST 1,2 2,1 I want to get the friends and friends of friends of an specific user. The select should return columns a, b, c. a: user_id b: friend_id c: username (username of friend_id ) If 1 is friend of 2 and 3. 2 is friend of 3, 4 and 5 3 is friend of 5,6,7 Then the query to get 1's friends and friends of friends should return: 1 2 two 1 3 three 2 1 one 2 3 three 2 4 four 2 5 five 3 1 one 3 5 five 3 6 six 3 7 seven Can I get this rows with a single query?

  public function getHelperInstance() { $user = new Helper(); $user->set($result['data']); return $user; } I am calling getHelper() class multiple times and if $user is not empty than am calling getHelperInstance(), now in my case getHelperInstance() always creates a new instance of Helper() class and so every time I call getHelperInstance() function am creating a new instance of Helper() so is there any way where can I can just create one instance of Helper() and use it multiple times instead of creating a new instance everytime. Any suggestions !!! public function getHelper() { $user = array(); if (!empty($user)) { $user = $this->getHelperInstance(); } return $user; }

• VS 2010 Entity Repository Error Class member EntityBase.id is unmapped.

• Sort a 2D Points List (first by X and then Y)

  - by Mikos

  I am trying to sort a List of 2D Points first by x co-ordinate and then by y co-ordinate. I implemented the IComparer interface as follows: class PointComparer : IComparer<Point> { public int Compare(Point x, Point y) { if (x.Y != y.Y) { return x.Y - y.Y; } else { return x.X - y.X; } } } And then call my sorting as follows: pointsList.Sort(new PointComparer()); For some reason the list doesn't sort. Surely is something very simple and silly, but stuck on this for quite a while....TIA

• Simple RSA encryption (Java)

  - by jake blue

  This is simply for fun. This will not be used for any actual encryption. I'm only first year comp sci student and love cryptography. This took a long time to get working.

• Basic class returns onject reference instead of Array

But what I want is the MySQL row array from the mysql_fetch_row() call... What am I missing?

• C++ method chaining including class constructor

  - by jena

  Hello, I'm trying to implement method chaining in C++, which turns out to be quite easy if the constructor call of a class is a separate statement, e.g: Foo foo; foo.bar().baz(); But as soon as the constructor call becomes part of the method chain, the compiler complains about expecting ";" in place of "." immediately after the constructor call: Foo foo().bar().baz(); I'm wondering now if this is actually possible in C++. Here is my test class: class Foo { public: Foo() { } Foo& bar() { return *this; } Foo& baz() { return *this; } }; I also found an example for "fluent interfaces" in C++ (http://en.wikipedia.org/wiki/Fluent_interface#C.2B.2B) which seems to be exactly what I'm searching for. However, I get the same compiler error for that code. Thanks in advance for any hint. Best, Jean

• How do I write an overload operator where both arguments are interface

• How can I add a field with an array value to my Perl object?

How do I do it with the second constructor and how can we use get and set methods on those array variables?

• c# event fires windows form incorrectly

  - by MikeW

  I'm trying to understand what's happening here. I have a CheckedListBox which contains some ticked and some un-ticked items. I'm trying to find a way of determining the delta in the selection of controls. I've tried some cumbersome like this - but only works part of the time, I'm sure there's a more elegant solution. A maybe related problem is the myCheckBox_ItemCheck event fires on form load - before I have a chance to perform an ItemCheck. Here's what I have so far: void clbProgs_ItemCheck(object sender, ItemCheckEventArgs e) { // i know its awful System.Windows.Forms.CheckedListBox cb = (System.Windows.Forms.CheckedListBox)sender; string sCurrent = e.CurrentValue.ToString(); int sIndex = e.Index; AbstractLink lk = (AbstractLink)cb.Items[sIndex]; List<ILink> _links = clbProgs.DataSource as List<ILink>; foreach (AbstractLink lkCurrent in _links) { if (!lkCurrent.IsActive) { if (!_groupValues.ContainsKey(lkCurrent.Linkid)) { _groupValues.Add(lkCurrent.Linkid, lkCurrent); } } } if (_groupValues.ContainsKey(lk.Linkid)) { AbstractLink lkDirty = (AbstractLink)lk.Clone(); CheckState newValue = (CheckState)e.NewValue; if (newValue == CheckState.Checked) { lkDirty.IsActive = true; } else if (newValue == CheckState.Unchecked) { lkDirty.IsActive = false; } if (_dirtyGroups.ContainsKey(lk.Linkid)) { _dirtyGroups[lk.Linkid] = lkDirty; } else { CheckState oldValue = (CheckState)e.NewValue; if (oldValue == CheckState.Checked) { lkDirty.IsActive = true; } else if (oldValue == CheckState.Unchecked) { lkDirty.IsActive = false; } _dirtyGroups.Add(lk.Linkid, lk); } } else { if (!lk.IsActive) { _dirtyGroups.Add(lk.Linkid, lk); } else { _groupValues.Add(lk.Linkid, lk); } } } Then onclick of a save button - I check whats changed before sending to database: private void btSave_Click(object sender, EventArgs e) { List<AbstractLink> originalList = new List<AbstractLink>(_groupValues.Values); List<AbstractLink> changedList = new List<AbstractLink>(_dirtyGroups.Values); IEnumerable<AbstractLink> dupes = originalList.ToArray<AbstractLink>().Intersect(changedList.ToArray<AbstractLink>()); foreach (ILink t in dupes) { MessageBox.Show("Changed"); } if (dupes.Count() == 0) { MessageBox.Show("No Change"); } } For further info. The definition of type AbstractLink uses: public bool Equals(ILink other) { if (Object.ReferenceEquals(other, null)) return false; if (Object.ReferenceEquals(this, other)) return true; return IsActive.Equals(other.IsActive) && Linkid.Equals(other.Linkid); }

• Run Oracle Procedure just to lock row, without returning a resultset

Below is the proc: CREATE OR REPLACE PROCEDURE SP_LOCK_Row (IDRow IN INTEGER) IS BEGIN SELECT * FROM TBLTable WHERE IDRow = IDRow FOR UPDATE; END; The problem is that I keep getting the error: PLS-00428: an INTO clause is expected in this SELECT statement.
