  • LINQ to XML Cloning

    - by Sir Psycho
    Can anyone explain why the original address XElement street node changes? It looks like customer1 holds a reference to the address XElement but customer2 and customer3 have taken copies. Why did the original address change? (LINQPad example) var address = new XElement ("address", new XElement ("street", "Lawley St"), new XElement ("town", "North Beach") ); var customer1 = new XElement ("customer1", address); var customer2 = new XElement ("customer2", address); var customer3 = new XElement ("customer3", address); customer1.Element ("address").Element ("street").Value = "Another St"; Console.WriteLine (customer2.Element ("address").Element ("street").Value); Console.WriteLine (); address.Dump(); Console.WriteLine (); customer1.Dump(); Console.WriteLine (); customer2.Dump(); Console.WriteLine (); customer3.Dump(); OUTPUT Lawley St <address> <street>Another St</street> <town>North Beach</town> </address> <customer1> <address> <street>Another St</street> <town>North Beach</town> </address> </customer1> <customer2> <address> <street>Lawley St</street> <town>North Beach</town> </address> </customer2> <customer3> <address> <street>Lawley St</street> <town>North Beach</town> </address> </customer3>

  • Due Date set via EWS is wrong in reminder popup

    - by Paul McLean
    I'm having some trouble using EWS with tasks and reminders, specifically, the due date. When I run my code, shown below, the task is added to my exchange account and I can see it fine in outlook. All the data in it looks fine too. However, if I specify to have a reminder for the task, the due date it shows is very wrong. It's usually 17 hours in the future, but the screenshot I've provided shows it being 19 hours in the future. I'm finding it very strange that if I open the task, the due date looks fine, but the reminder is saying it is due well into the future. Any ideas? Screenshot: http://s970.photobucket.com/albums/ae187/paulehn/?action=view&current=ewstask.jpg ExchangeVersion exchVersion = new ExchangeVersion(); exchVersion = ExchangeVersion.Exchange2007_SP1; ExchangeService service = new ExchangeService(exchVersion); service.UseDefaultCredentials = true; service.Url = new Uri("https://mail.domain.com.au/ews/exchange.asmx"); Task task = new Task(service); task.Subject = "Subject"; task.Body = new MessageBody(BodyType.HTML, "Body"); task.StartDate = DateTime.Today; task.DueDate = DateTime.Now.AddHours(2); task.ReminderDueBy = DateTime.Now; task.ReminderMinutesBeforeStart = 15; task.IsReminderSet = true; task.Save();

  • How do you: Symfony functional test on a secure app?

  • How to completely wipe a previous ClickOnce installation?

    - by Dabblernl
    I have a curious problem: My app is distributed through ClickOnce. I recently installed three new clients on a new location. They worked. After an update however, all old clients worked fine, but the three new clients did not. As my code is swallowing an exception somewhere I have been unable thusfar to pinpoint where the error lies. When I XCopy the latest version of the app to the desktop of the three new client computers the program works fine. So, I thought uninstalling and reinstalling the program from the download location should fix the problem, but it does not! I can think of two explanations: The new location has some firewall/virusscanner in place that doesn't like the latest version of my app when it is run from a standard ClickOnce directory, but it allows execution from the desktop. Some old settings (the app uses user scoped and app scoped settings) remain in effect after the uninstall. When I find and check the user.config file for the app however, I find no incorrect setttings there. Thusfar, I have been unable to reproduce the error on any other machine. How can I solve this!?

  • Render a view as a string

    - by Dan Atkinson
    Hi all! I'm wanting to output two different views (one as a string that will be sent as an email), and the other the page displayed to a user. Is this possible in ASP.NET MVC beta? I've tried multiple examples: RenderPartial to String in ASP.NET MVC Beta If I use this example, I receive the "Cannot redirect after HTTP headers have been sent.". MVC Framework: Capturing the output of a view If I use this, I seem to be unable to do a redirectToAction, as it tries to render a view that may not exist. If I do return the view, it is completely messed up and doesn't look right at all. Does anyone have any ideas/solutions to these issues i have, or have any suggestions for better ones? Many thanks! Below is an example. What I'm trying to do is create the GetViewForEmail method: public ActionResult OrderResult(string ref) { //Get the order Order order = OrderService.GetOrder(ref); //The email helper would do the meat and veg by getting the view as a string //Pass the control name (OrderResultEmail) and the model (order) string emailView = GetViewForEmail("OrderResultEmail", order); //Email the order out EmailHelper(order, emailView); return View("OrderResult", order); } Accepted answer from Tim Scott (changed and formatted a little by me): public virtual string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) { filter.Dispose(); } //Now replace the response filter response.Filter = oldFilter; } } Example usage Assuming a call from the controller to get the order confirmation email, passing the Site.Master location. string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData);

  • RMI no such object in table, Server communication error

    - by ben-casey
    My goal is to create a Distributed computing program that launches a server and client at the same time. I need it to be able to install on a couple of machines and have all the machines communicating with each other, i.e. Master node and 5 slave nodes all from one application. My problem is that I cannot properly use unicastRef, I'm thinking that it is a problem with launching everything on the same port, is there a better way I am overlooking? this is part of my code (the part that matters) try { RMIServer obj = new RMIServer(); obj.start(5225); } catch (Exception e) { e.printStackTrace(); } try { System.out.println("We are slave's "); Registry rr = LocateRegistry.getRegistry("127.0.0.1", Store.PORT, new RClient()); Call ss = (Call) rr.lookup("FILLER"); System.out.println(ss.getHello()); } catch (Exception e) { e.printStackTrace(); } } this is my main class (above) this is the server class (below) public RMIServer() { } public void start(int port) throws Exception { try { Registry registry = LocateRegistry.createRegistry(port, new RClient(), new RServer()); Call stuff = new Call(); registry.bind("FILLER", stuff); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } I don't know what I am missing or what I am overlooking but the output looks like this.

  • Google Maps Rollover Problem in a Flex Website

    - by Laxmidi
    Hi, I'm using Google Maps in my Flex site to create a map. I've got polygons overlayed on the map. When the user rolls over a polygon an infowindow opens identifying the area and the fill Alpha of the area is set to 0. On roll-out, the info window is removed and the fill Alpha is returned to the default, 0.2. The polygons display and the InfoWindow is added and removed correctly. The problem is that the change in fill alpha only occurs on the very last polygon in the list. So for example, if I have polygons A, B, C, and D. If I rollover A, then A's alpha should change. But, instead D's alpha changes. No matter which polygon I rollover, the last polygon's alpha changes. It's weird, because the infoWindows behave correctly on rollover. So, if I rollover polygon A, the correct information for InfoWindow A appears. Please see the code below: private function allEncodedPolygons(event:MouseEvent) : void { var myPaneManager:IPaneManager = map.getPaneManager(); var myMapPane:IPane = myPaneManager.createPane(); if (allHoodsToggle.selected) { map.clearOverlays(); mapType.selectedIndex = -1; for each (var neighbNode:XML in detailMapResultData){ outlinePolygon = this.createPoly(neighbNode); map.addOverlay(outlinePolygon)}; allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } else {myPaneManager.clearOverlays(); allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } } The function below creates the polygons and has the rollover function: private var neighbShapes:Polygon; private function createPoly(neighbNode:XML):Polygon { var optionsDefault:PolygonOptions = new PolygonOptions( { strokeStyle: {thickness: 5, color: 0xFFFF00, alpha: 0.4, pixelHinting: true}, fillStyle: { alpha: 0.2 }} ); var neighbCenterLat:Number = neighbNode.latitudeCenter.toString(); var neighbCenterLong:Number = neighbNode.longitudeCenter.toString(); var neighbCenter:LatLng = new LatLng(neighbCenterLat,neighbCenterLong); var optionsHover:PolygonOptions = new PolygonOptions( { fillStyle: { alpha: 0.0 }} ); var encodedData:EncodedPolylineData = new EncodedPolylineData(neighbNode.encoding.toString(), neighbNode.zoomFactor.toString(), neighbNode.level.toString(), neighbNode.numlevels.toString()); var encodedList:Array = [encodedData]; neighbShapes = Polygon.fromEncoded(encodedList, optionsDefault); neighbShapes.addEventListener(MapMouseEvent.CLICK, function(event:MapMouseEvent): void { map.openInfoWindow(event.latLng, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:true})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OVER, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsHover); map.openInfoWindow(neighbCenter, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:false})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OUT, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsDefault); }); return neighbShapes; } Any suggestions as to why the function that changes the alpha is firing on the last polygon only, even though the InfoWindow appears correctly? If anyone has any ideas, I'd love to hear them. Thanks. -Laxmidi

  • How do you save compare options in Visual Studio 2010 > SQL 2012 Database Project

    - by profMamba
    Been using the new SQL 2012 Data Tools SQL Server Database Project in VS 2010. Every time we do a schema compare we have to set the options for the current compare. This does not seem to be tied back to the global compare options you can set in Tools Options. Does anybody know where to set the 'new' global compare options. NOTE: This is the new SQL 2012 compare from Data Tools, and not the old 2005/2008 compare that comes standard with Studio 2010.

  • Why is Swing Parser's handleText not handling nested tags?

    - by Jim P
    I need to transform some HTML text that has nested tags to decorate 'matches' with a css attribute to highlight it (like firefox search). I can't just do a simple replace (think if user searched for "img" for example), so I'm trying to just do the replace within the body text (not on tag attributes). I have a pretty straightforward HTML parser that I think should do this: final Pattern pat = Pattern.compile(srch, Pattern.CASE_INSENSITIVE); Matcher m = pat.matcher(output); if (m.find()) { final StringBuffer ret = new StringBuffer(output.length()+100); lastPos=0; try { new ParserDelegator().parse(new StringReader(output.toString()), new HTMLEditorKit.ParserCallback () { public void handleText(char[] data, int pos) { ret.append(output.subSequence(lastPos, pos)); Matcher m = pat.matcher(new String(data)); ret.append(m.replaceAll("<span class=\"search\">$0</span>")); lastPos=pos+data.length; } }, false); ret.append(output.subSequence(lastPos, output.length())); return ret; } catch (Exception e) { return output; } } return output; My problem is, when I debug this, the handleText is getting called with text that includes tags! It's like it's only going one level deep. Anyone know why? Is there some simple thing I need to do to HTMLParser (haven't used it much) to enable 'proper' behavior of nested tags? PS - I figured it out myself - see answer below. Short answer is, it works fine if you pass it HTML, not pre-escaped HTML. Doh! Hope this helps someone else. <span>example with <a href="#">nested</a> <p>more nesting</p> </span> <!-- all this gets thrown together -->

  • CellTable + AsyncListViewAdapter<T> + SimplePager<T>, stuck with 'loading' bar when paging

    - by Jaroslav Záruba
    Hi I'm trying to make CellTable, AsyncListViewAdapter<T> and SimplePager<T> working together. I managed to display my data, but whenever I click either "go to start" or "go to end" button I get that 'loading' indicator which stays there till the end of days. (And AsyncListViewAdapter<T>.onRangeChanged doesn't even get called this time.) I went through the code-snippets in this thread, but I can't see nothing suspicions in what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { // doesn't get called on go2start/go2end :( Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO namespace) { return namespace.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J.

  • Designer serialization persistence problem in .NET, Windows Forms

    - by Jules
    ETA: I have a similar, smaller, problem here which, I suspect, is related to this problem. I have a class which has a readonly property that holds a collection of components (* not quite, see below). At design time, it's possible to select from the components on the design surface to add to the collection. (Think imagelist, but instead of selecting one, you can select as many as you want.) As a test, I inherit from button and attach my class to it as a property. The persistence problem occurs when I add a component,to the collection, from the design surface after I have added my button to the form. The best way to demonstrate this is to show you the designer generated code: Private Sub InitializeComponent() Dim Provider1 As WindowsApplication1.Provider = New WindowsApplication1.Provider Me.MyComponent2 = New WindowsApplication1.MyComponent Me.MyComponent1 = New WindowsApplication1.MyComponent Me.MyButton1 = New WindowsApplication1.MyButton Me.MyComponent3 = New WindowsApplication1.MyComponent Me.SuspendLayout() ' 'MyButton1 ' Me.MyButton1.ProviderCollection.Add(Me.MyButton1.InternalProvider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent1.Provider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent2.Provider) Me.MyButton1.ProviderCollection.Add(Provider1) //Wrong should be Me.MyComponent3.Provider ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub Friend WithEvents MyComponent1 As WindowsApplication1.MyComponent Friend WithEvents MyComponent2 As WindowsApplication1.MyComponent Friend WithEvents MyButton1 As WindowsApplication1.MyButton Friend WithEvents MyComponent3 As WindowsApplication1.MyComponent End Class As you can see from the code, the collection is not actually a collection of the components, but a collection of a property, 'Provider', from the components. It looks like the problem is occurring because MyComponent3 is created after MyButton. However, in my opinion, this should not make any difference - by the time the serializer comes to add the provider property of MyComponent3, it's already created. Note: You may wonder, why I'm not using AddRange to persist the collection. The reason for this is that if I do, the behaviour changes and none of the items will persist correctly. The designer will create local fields - like Provider1 - for each item in the collection. However if I add another collection to the class which holds the actual MyComponents and persist this, then, somehow, the AddRange method persists correctly in ProviderCollection! There seems to be some kind of quantum double slit experiment going down in code dom. How can I solve this problem?

  • Unit test for Web Forms MVP presenter has a null Model

    - by jacksonakj
    I am using Web Forms MVP to write an DotNetNuke user control. When the 'SubmitContactUs' event is raised in my unit test the presenter attempts to set the 'Message' property on the Modal. However the View.Modal is null in the presenter. Shouldn't the Web Forms MVP framework automatically build a new View.Model object in the presenter? It could be that the 'Arrange' portion of my test is missing something that the presenter needs. Any help would be appreciated. Here is my test: using System; using AthleticHost.ContactUs.Core.Presenters; using AthleticHost.ContactUs.Core.Views; using Xunit; using Moq; namespace AthleticHost.ContactUs.Tests { public class ContactUsPresenterTests { [Fact] public void ContactUsPresenter_Sets_Message_OnSubmit() { // Arrange var view = new Mock<IContactUsView>(); var presenter = new ContactUsPresenter(view.Object); // Act view.Raise(v => v.Load += null, new EventArgs()); view.Raise(v => v.SubmitContactUs += null, new SubmitContactUsEventArgs("Chester", "Tester", "[email protected]", "http://www.test.com", "This is a test of the emergancy broadcast system...")); presenter.ReleaseView(); // Assert Assert.Contains("Chester Tester", view.Object.Model.Message); } } }

  • Compilation problems with vector<auto_ptr<> >

    - by petersohn
    Consider the following code: #include <iostream> #include <memory> #include <vector> using namespace std; struct A { int a; A(int a_):a(a_) {} }; int main() { vector<auto_ptr<A> > as; for (int i = 0; i < 10; i++) { auto_ptr<A> a(new A(i)); as.push_back(a); } for (vector<auto_ptr<A> >::iterator it = as.begin(); it != as.end(); ++it) cout << (*it)->a << endl; } When trying to compile it, I get the following obscure compiler error from g++: g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/proba.d" -MT"src/proba.d" -o"src/proba.o" "../src/proba.cpp" /usr/include/c++/4.1.2/ext/new_allocator.h: In member function ‘void __gnu_cxx::new_allocator<_Tp>::construct(_Tp*, const _Tp&) [with _Tp = std::auto_ptr<A>]’: /usr/include/c++/4.1.2/bits/stl_vector.h:606: instantiated from ‘void std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = std::auto_ptr<A>, _Alloc = std::allocator<std::auto_ptr<A> >]’ ../src/proba.cpp:19: instantiated from here /usr/include/c++/4.1.2/ext/new_allocator.h:104: error: passing ‘const std::auto_ptr<A>’ as ‘this’ argument of ‘std::auto_ptr<_Tp>::operator std::auto_ptr_ref<_Tp1>() [with _Tp1 = A, _Tp = A]’ discards qualifiers /usr/include/c++/4.1.2/bits/vector.tcc: In member function ‘void std::vector<_Tp, _Alloc>::_M_insert_aux(__gnu_cxx::__normal_iterator<typename std::_Vector_base<_Tp, _Alloc>::_Tp_alloc_type::pointer, std::vector<_Tp, _Alloc> >, const _Tp&) [with _Tp = std::auto_ptr<A>, _Alloc = std::allocator<std::auto_ptr<A> >]’: /usr/include/c++/4.1.2/bits/stl_vector.h:610: instantiated from ‘void std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = std::auto_ptr<A>, _Alloc = std::allocator<std::auto_ptr<A> >]’ ../src/proba.cpp:19: instantiated from here /usr/include/c++/4.1.2/bits/vector.tcc:256: error: passing ‘const std::auto_ptr<A>’ as ‘this’ argument of ‘std::auto_ptr<_Tp>::operator std::auto_ptr_ref<_Tp1>() [with _Tp1 = A, _Tp = A]’ discards qualifiers /usr/include/c++/4.1.2/bits/stl_construct.h: In function ‘void std::_Construct(_T1*, const _T2&) [with _T1 = std::auto_ptr<A>, _T2 = std::auto_ptr<A>]’: /usr/include/c++/4.1.2/bits/stl_uninitialized.h:86: instantiated from ‘_ForwardIterator std::__uninitialized_copy_aux(_InputIterator, _InputIterator, _ForwardIterator, __false_type) [with _InputIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >, _ForwardIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >]’ /usr/include/c++/4.1.2/bits/stl_uninitialized.h:113: instantiated from ‘_ForwardIterator std::uninitialized_copy(_InputIterator, _InputIterator, _ForwardIterator) [with _InputIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >, _ForwardIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >]’ /usr/include/c++/4.1.2/bits/stl_uninitialized.h:254: instantiated from ‘_ForwardIterator std::__uninitialized_copy_a(_InputIterator, _InputIterator, _ForwardIterator, std::allocator<_Tp>) [with _InputIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >, _ForwardIterator = __gnu_cxx::__normal_iterator<std::auto_ptr<A>*, std::vector<std::auto_ptr<A>, std::allocator<std::auto_ptr<A> > > >, _Tp = std::auto_ptr<A>]’ /usr/include/c++/4.1.2/bits/vector.tcc:279: instantiated from ‘void std::vector<_Tp, _Alloc>::_M_insert_aux(__gnu_cxx::__normal_iterator<typename std::_Vector_base<_Tp, _Alloc>::_Tp_alloc_type::pointer, std::vector<_Tp, _Alloc> >, const _Tp&) [with _Tp = std::auto_ptr<A>, _Alloc = std::allocator<std::auto_ptr<A> >]’ /usr/include/c++/4.1.2/bits/stl_vector.h:610: instantiated from ‘void std::vector<_Tp, _Alloc>::push_back(const _Tp&) [with _Tp = std::auto_ptr<A>, _Alloc = std::allocator<std::auto_ptr<A> >]’ ../src/proba.cpp:19: instantiated from here /usr/include/c++/4.1.2/bits/stl_construct.h:81: error: passing ‘const std::auto_ptr<A>’ as ‘this’ argument of ‘std::auto_ptr<_Tp>::operator std::auto_ptr_ref<_Tp1>() [with _Tp1 = A, _Tp = A]’ discards qualifiers make: *** [src/proba.o] Error 1 It seems to me that there is some kind of problem with consts here.

  • ServiceTracker in OSGi r4.1

    - by Schildmeijer
    Im using a org.osgi.util.tracker.ServiceTracker (PrintableServiceTracker implements ServiceTrackerCustomizer and simply prints when a new service is added). Filter filter = bc.createFilter("(objectClass=se.enea.print.Printable)"); tracker = new ServiceTracker(bc, filter, new PrintableServiceTracker(bc)); I've read about "pseudo registration" in the new ebook "OSGi in action" and I wonder if I have to do pseudo registration explicitly or if the framwork handles this automatically? (Will already installed Printable services be caught by the ServiceTracker. will ServiceTracker.addingService(ServiceReference) be called for each of the pre installed Printable services)

  • Export Multiple Crystal Reports ASP.NET

    - by AProgrammer
    Hey all, I want to export 2 different reports when I click an Export button. The problem is the routine only fires once and I only get one report to print out. Am I doing something wrong? I think it has something to do with the HTTPResponse, but I'm not sure.

  • C# Chain-of-responsibility with delegates

    For my understanding purpose i have implemented Chain-Of-Responsibility pattern. //Abstract Base Type public abstract class CustomerServiceDesk { protected CustomerServiceDesk _nextHandler; public abstract void ServeCustomers(Customer _customer); public void SetupHadler(CustomerServiceDesk _nextHandler) { this._nextHandler = _nextHandler; } } public class FrontLineServiceDesk:CustomerServiceDesk { public override void ServeCustomers(Customer _customer) { if (_customer.ComplaintType == ComplaintType.General) { Console.WriteLine(_customer.Name + " Complaints are registered ; will be served soon by FrontLine Help Desk.."); } else { Console.WriteLine(_customer.Name + " is redirected to Critical Help Desk"); _nextHandler.ServeCustomers(_customer); } } } public class CriticalIssueServiceDesk:CustomerServiceDesk { public override void ServeCustomers(Customer _customer) { if (_customer.ComplaintType == ComplaintType.Critical) { Console.WriteLine(_customer.Name + "Complaints are registered ; will be served soon by Critical Help Desk"); } else if (_customer.ComplaintType == ComplaintType.Legal) { Console.WriteLine(_customer.Name + "is redirected to Legal Help Desk"); _nextHandler.ServeCustomers(_customer); } } } public class LegalissueServiceDesk :CustomerServiceDesk { public override void ServeCustomers(Customer _customer) { if (_customer.ComplaintType == ComplaintType.Legal) { Console.WriteLine(_customer.Name + "Complaints are registered ; will be served soon by legal help desk"); } } } public class Customer { public string Name { get; set; } public ComplaintType ComplaintType { get; set; } } public enum ComplaintType { General, Critical, Legal } void Main() { CustomerServiceDesk _frontLineDesk = new FrontLineServiceDesk(); CustomerServiceDesk _criticalSupportDesk = new CriticalIssueServiceDesk(); CustomerServiceDesk _legalSupportDesk = new LegalissueServiceDesk(); _frontLineDesk.SetupHadler(_criticalSupportDesk); _criticalSupportDesk.SetupHadler(_legalSupportDesk); Customer _customer1 = new Customer(); _customer1.Name = "Microsoft"; _customer1.ComplaintType = ComplaintType.General; Customer _customer2 = new Customer(); _customer2.Name = "SunSystems"; _customer2.ComplaintType = ComplaintType.Critical; Customer _customer3 = new Customer(); _customer3.Name = "HP"; _customer3.ComplaintType = ComplaintType.Legal; _frontLineDesk.ServeCustomers(_customer1); _frontLineDesk.ServeCustomers(_customer2); _frontLineDesk.ServeCustomers(_customer3); } Question Without breaking the chain-of-responsibility ,how can i apply delegates and events to rewrite the code?
