  • Clonezilla disk to disk clone on a dual boot ubuntu karmic & XP setup - cannot open '/boot/grub/devi

    - by srboisvert
    I just tried to clone a failing existing boot drive for a dual boot system with Ubuntu karmic and Windows XP installed using Clonezilla. The cloning worked fine right up until the end when I got the following error: Running: grub-install --no floppy --root-directory=/tmp/hd_img.twABYW /dev/sdb grub-probe: error: Cannot open '/boot/grub/device.map' /usr/sbin/grub-install:line 374: [: =: unary operator expected What's my next step? I imagine I need to somehow rebuild my boot record for Windows and Ubuntu and edit grub.

  • Binding to WPF ViewModel properties

    - by MartinHN
    I'm just playing around with WPF and MVVM, and I have made a simple app that displays a Rectangle that changes color whenever Network availability changes. But when that happens, I get this error: Cannot use a DependencyObject that belongs to a different thread than its parent Freezable. Code XAML <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="400" Width="600"> <DockPanel LastChildFill="True"> <Rectangle x:Name="networkStatusRectangle" Width="200" Height="200" Fill="{Binding NetworkStatusColor}" /> </DockPanel> </Window> Code-behind using System.Windows; using WpfApplication1.ViewModels; namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new NetworkViewModel(); } } } ViewModel using System.ComponentModel; using System.Net.NetworkInformation; using System.Windows.Media; namespace WpfApplication1.ViewModels { public class NetworkViewModel : INotifyPropertyChanged { private Brush _NetworkStatusColor; public Brush NetworkStatusColor { get { return _NetworkStatusColor; } set { _NetworkStatusColor = value; NotifyOfPropertyChange("NetworkStatusColor"); } } public NetworkViewModel() { NetworkChange.NetworkAvailabilityChanged += new NetworkAvailabilityChangedEventHandler(NetworkChange_NetworkAvailabilityChanged); } protected void NetworkChange_NetworkAvailabilityChanged(object sender, NetworkAvailabilityEventArgs e) { if (e.IsAvailable) { this.NetworkStatusColor = new SolidColorBrush(Colors.Green); } else { this.NetworkStatusColor = new SolidColorBrush(Colors.Red); } } public event PropertyChangedEventHandler PropertyChanged = delegate { }; public void NotifyOfPropertyChange(string propertyName) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } } I assume that I should change the NetworkStatusColor property by invoking something?

  • Jetty 6 - QueuedThreadPool versus ThreadPool

    - by Walter White
    Hi all, I am using Jetty 6 and was wondering when the QueuedThreadPool should be used over the ThreadPool? By default, Jetty 6 comes configured with the QueuedThreadPool. My server has Java 6 installed so I was thinking that I should use the ThreadPool: <New class="org.mortbay.thread.QueuedThreadPool"> <Set name="minThreads">10</Set> <Set name="maxThreads">200</Set> <Set name="lowThreads">20</Set> <Set name="SpawnOrShrinkAt">2</Set> </New> <New class="org.mortbay.thread.concurrent.ThreadPool"> <Set name="corePoolSize">50</Set> <Set name="maximumPoolSize">50</Set> </New> Thanks, Walter

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • NullReferenceException when testing DefaultModelBinder.

    - by Byron Sommardahl
    I'm developing a project using BDD/TDD techniques and I'm trying my best to stay the course. A problem I just ran into is unit testing the DefaultModelBinder. I'm using mspec to write my tests. I have a class like this that I want to bind to: public class EmailMessageInput : IMessageInput { public object Recipient { get; set; } public string Body { get; set; } } Here's how I'm building my spec context. I'm building a fake form collection and stuffing it into a bindingContext object. public abstract class given_a_controller_with_valid_email_input : given_a_controller_context { Establish additional_context = () => { var form = new FormCollection { new NameValueCollection { { "EmailMessageInput.Recipient", "[email protected]"}, { "EmailMessageInput.Body", "Test body." } } }; _bindingContext = new ModelBindingContext { ModelName = "EmailMessageInput", ValueProvider = form }; _modelBinder = new DefaultModelBinder(); }; protected static ModelBindingContext _bindingContext; protected static DefaultModelBinder _modelBinder; } public abstract class given_a_controller_context { protected static MessageController _controller; Establish context = () => { _controller = new MessageController(); }; } Finally, my spec throws an null reference exception when I execute .BindModel() from inside one of my specs: Because of = () => { _model = _modelBinder.BindModel(_controller.ControllerContext, _bindingContext); }; Any clue what it could be? Feel free to ask me for more info, if needed. I might have taken something for granted.

  • Should an event-sourced aggregate root have query access to the event sourcing repository?

    - by JD Courtoy
    I'm working on an event-sourced CQRS implementation, using DDD in the application / domain layer. I have an object model that looks like this: public class Person : AggregateRootBase { private Guid? _bookingId; public Person(Identification identification) { Apply(new PersonCreatedEvent(identification)); } public Booking CreateBooking() { // Enforce Person invariants var booking = new Booking(); Apply(new PersonBookedEvent(booking.Id)); return booking; } public void Release() { // Enforce Person invariants // Should we load the booking here from the aggregate repository? // We need to ensure that booking is released as well. var booking = BookingRepository.Load(_bookingId); booking.Release(); Apply(new PersonReleasedEvent(_bookingId)); } [EventHandler] public void Handle(PersonBookedEvent @event) { _bookingId = @event.BookingId; } [EventHandler] public void Handle(PersonReleasedEvent @event) { _bookingId = null; } } public class Booking : AggregateRootBase { private DateTime _bookingDate; private DateTime? _releaseDate; public Booking() { //Enforce invariants Apply(new BookingCreatedEvent()); } public void Release() { //Enforce invariants Apply(new BookingReleasedEvent()); } [EventHandler] public void Handle(BookingCreatedEvent @event) { _bookingDate = SystemTime.Now(); } [EventHandler] public void Handle(BookingReleasedEvent @event) { _releaseDate = SystemTime.Now(); } // Some other business activities unrelated to a person } With my understanding of DDD so far, both Person and Booking are seperate aggregate roots for two reasons: There are times when business components will pull Booking objects separately from the database. (ie, a person that has been released has a previous booking modified due to incorrect information). There should not be locking contention between Person and Booking whenever a Booking needs to be updated. One other business requirement is that a Booking can never occur for a Person more than once at a time. Due to this, I'm concerned about querying the query database on the read side as there could potentially be some inconsistency there (due to using CQRS and having an eventually consistent read database). Should the aggregate roots be allowed to query the event-sourced backing store for objects (lazy-loading them as needed)? Are there any other avenues of implementation that would make more sense?

  • Setting Background of a Jbutton

    - by mithun1538
    Hello there, I have 5 JButtons: b1, b2, b3, b4, b5. By default, their color is gray. When I click on any button, the background of that button changes to white. When I click another button, I want that previous clicked button to change its background to gray, and this newly clicked button to change its background to white. Here is the code that I wrote: int liveButton = 0; //holds the value of the button that is last clicked. //0 indicates no button clicked (in the beginning) private void ChangeInUsersList(int clickedButton) { switch(liveButton) { case 1 : b1.setBackground(Color.GRAY); break; case 2 : b2.setBackground(Color.GRAY); break; case 3 : b3.setBackground(Color.GRAY); break; case 4 : b4.setBackground(Color.GRAY); break; case 5 : b5.setBackground(Color.GRAY); break; default: System.out.println("No button to change"); } liveButton = clickedButton;// store the clicked button to change its //background later } private void b1ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(1); b1.setBackground(new java.awt.Color(255,255,255)); } private void b2ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(2); b2.setBackground(new java.awt.Color(255,255,255)); } private void b3ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(3); b3.setBackground(new java.awt.Color(255,255,255)); } private void b4ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(4); b4.setBackground(new java.awt.Color(255,255,255)); } private void b5ButtonActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(5); b5.setBackground(new java.awt.Color(255,255,255)); } However, its not working as expected. When i click on a button, its background does change to white. However, if i click on some other button after that, the former button's background doesnt change to grey. I tried replacing Color.GREY with new java.awt.Color(236,233,216) - the rgb for grey but it still doesnt work.

  • Objective C: Create arrays from first array based on value

    - by Nic Hubbard
    I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

  • System.UnsupportedException using WCF on Windows Phone 7

    - by Igor Zevaka
    Has anyone been able to communicate using WCF on Windows Phone Series 7 emulator? I've been trying for the past two days and it's just happening for me. I can get a normal Silverlight control to work in both Silverlight 3 and Silverlight 4, but not the phone version. Here are two versions that I've tried: Version 1 - Using Async Pattern BasicHttpBinding basicHttpBinding = new BasicHttpBinding(); EndpointAddress endpointAddress = new EndpointAddress("http://localhost/wcf/Authentication.svc"); Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress); AsyncCallback callback = (result) => { Action<string> write = (str) => { this.Dispatcher.BeginInvoke(delegate { //Display something }); }; try { Wcf.IAuthentication auth = result.AsyncState as Wcf.IAuthentication; Wcf.AuthenticationResponse response = auth.EndLogin(result); write(response.Success.ToString()); } catch (Exception ex) { write(ex.Message); System.Diagnostics.Debug.WriteLine(ex.Message); } }; auth1.BeginLogin("user0", "test0", callback, auth1); This version breaks on this line: Wcf.IAuthentication auth1 = new ChannelFactory<Wcf.IAuthentication>(basicHttpBinding, endpointAddress).CreateChannel(endpointAddress); Throwing System.NotSupportedException. The exception is not very descriptive and the callstack is equally not very helpful: at System.ServiceModel.DiagnosticUtility.ExceptionUtility.BuildMessage(Exception x) at System.ServiceModel.DiagnosticUtility.ExceptionUtility.LogException(Exception x) at System.ServiceModel.DiagnosticUtility.ExceptionUtility.ThrowHelperError(Exception e) at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address) at WindowsPhoneApplication2.MainPage.DoLogin() .... Version 2 - Blocking WCF call Here is the version that doesn't use the async pattern. [System.ServiceModel.ServiceContract] public interface IAuthentication { [System.ServiceModel.OperationContract] AuthenticationResponse Login(string user, string password); } public class WcfClientBase<TChannel> : System.ServiceModel.ClientBase<TChannel> where TChannel : class { public WcfClientBase(string name, bool streaming) : base(GetBinding(streaming), GetEndpoint(name)) { ClientCredentials.UserName.UserName = WcfConfig.UserName; ClientCredentials.UserName.Password = WcfConfig.Password; } public WcfClientBase(string name) : this(name, false) {} private static System.ServiceModel.Channels.Binding GetBinding(bool streaming) { System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding(); binding.MaxReceivedMessageSize = 1073741824; if(streaming) { //binding.TransferMode = System.ServiceModel.TransferMode.Streamed; } /*if(XXXURLXXX.StartsWith("https")) { binding.Security.Mode = BasicHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; }*/ return binding; } private static System.ServiceModel.EndpointAddress GetEndpoint(string name) { return new System.ServiceModel.EndpointAddress(WcfConfig.Endpoint + name + ".svc"); } protected override TChannel CreateChannel() { throw new System.NotImplementedException(); } } auth.Login("test0", "password0"); This version crashes in System.ServiceModel.ClientBase<TChannel> constructor. The call stack is a bit different: at System.Reflection.MethodInfo.get_ReturnParameter() at System.ServiceModel.Description.ServiceReflector.HasNoDisposableParameters(MethodInfo methodInfo) at System.ServiceModel.Description.TypeLoader.CreateOperationDescription(ContractDescription contractDescription, MethodInfo methodInfo, MessageDirection direction, ContractReflectionInfo reflectionInfo, ContractDescription declaringContract) at System.ServiceModel.Description.TypeLoader.CreateOperationDescriptions(ContractDescription contractDescription, ContractReflectionInfo reflectionInfo, Type contractToGetMethodsFrom, ContractDescription declaringContract, MessageDirection direction) at System.ServiceModel.Description.TypeLoader.CreateContractDescription(ServiceContractAttribute contractAttr, Type contractType, Type serviceType, ContractReflectionInfo& reflectionInfo, Object serviceImplementation) at System.ServiceModel.Description.TypeLoader.LoadContractDescriptionHelper(Type contractType, Type serviceType, Object serviceImplementation) at System.ServiceModel.Description.TypeLoader.LoadContractDescription(Type contractType) at System.ServiceModel.ChannelFactory1.CreateDescription() at System.ServiceModel.ChannelFactory.InitializeEndpoint(Binding binding, EndpointAddress address) at System.ServiceModel.ChannelFactory1..ctor(Binding binding, EndpointAddress remoteAddress) at System.ServiceModel.ClientBase1..ctor(Binding binding, EndpointAddress remoteAddress) at Wcf.WcfClientBase1..ctor(String name, Boolean streaming) at Wcf.WcfClientBase`1..ctor(String name) at Wcf.AuthenticationClient..ctor() at WindowsPhoneApplication2.MainPage.DoLogin() ...

    I'm working on a PoSh project that generates CSharp code, and then Add-Types it into memory. The new types use existing types in an on disk DLL, which is loaded via Add-Type.

Here's an example of what I'm doing: $PWD = "." rm -Force $PWD\TestClassOne* $code = " namespace TEST{ public class TestClassOne { public int DoNothing() { return 1; } } }" $code | Out-File tcone.cs Add-Type -OutputAssembly $PWD\TestClassOne.dll -OutputType Library -Path $PWD\tcone.cs Add-Type -Path $PWD\TestClassOne.dll $a = New-Object TEST.TestClassOne "Using TestClassOne" $a.DoNothing() "Compiling TestClassTwo" Add-Type -Language CSharpVersion3 -TypeDefinition " namespace TEST{ public class TestClassTwo { public int CallTestClassOne() { var a = new TEST.TestClassOne(); return a.DoNothing(); } } }" -ReferencedAssemblies $PWD\TestClassOne.dll "OK" $b = New-Object TEST.TestClassTwo "Using TestClassTwo" $b.CallTestClassOne() Running the above script gives the following error on the last line: Exception calling "CallTestClassOne" with "0" argument(s): "Could not load file or assembly 'TestClassOne,...' or one of its dependencies. The system cannot find the file specified." At AddTypeTest.ps1:39 char:20 + $b.CallTestClassOne <<<< () + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException What am I doing wrong?

  • how to bind to the results of a query in WPF

    - by randyc
    I have a query that hits a service and returns the results back to me as an indexed collection static void QueryActivities() { QueryClient qc = new QueryClient("BasicHttpBinding_IQuery"); QueryFilter filter = new QueryFilter(); filter.CallForService = false; var result = qc.GetFilteredActivityIndex(filter); result.Clone(); //inserted this just to test return in debug mode } WHen this is executed I get a return of 5 records ( actually five rows of data with multiple values per each row. id, type, date, address etc). I would like to bind this return to a gridview within a WPF application. Is there a way to refernce and bind to result variable or do I need to create a new collection and then add the return of result to the new collection? thank you

  • java TrayIcon using image with transparent background

    - by Jack
    I am using the following code to set a tray icon in Windows and Linux. It works wonderful in Windows and works okay in Linux. In Linux (Ubuntu) I have my panel set to be (somewhat) transparent and when I add a GIF (with a transparent background) the background of the icon shows up all grey and ugly (see image, green diamond "!")....Any ideas on how to make the GIF image I am adding "keep" its transparent background? and the image I am using, if you'd like to test: import java.awt.*; import java.awt.event.*; public class TrayFun { static class ShowMessageListener implements ActionListener { TrayIcon trayIcon; String title; String message; TrayIcon.MessageType messageType; ShowMessageListener( TrayIcon trayIcon, String title, String message, TrayIcon.MessageType messageType) { this.trayIcon = trayIcon; this.title = title; this.message = message; this.messageType = messageType; } public void actionPerformed(ActionEvent e) { trayIcon.displayMessage(title, message, messageType); } } public static void main(String args[]) { Runnable runner = new Runnable() { public void run() { if (SystemTray.isSupported()) { final SystemTray tray = SystemTray.getSystemTray(); Image image = Toolkit.getDefaultToolkit().getImage("green_info.png"); PopupMenu popup = new PopupMenu(); final TrayIcon trayIcon = new TrayIcon(image, "The Tip Text", popup); trayIcon.setImageAutoSize(true); MenuItem item = new MenuItem("Close"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { tray.remove(trayIcon); } }); popup.add(item); try { tray.add(trayIcon); } catch (AWTException e) { System.err.println("Can't add to tray"); } } else { System.err.println("Tray unavailable"); } } }; EventQueue.invokeLater(runner); } }

  • Linq-to-sql Compiled Query is returning result from different DataContext

    - by Vladimir Kojic
    Compiled query: public static Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault()); It looks like compiled query is caching Machine object and returning the same object even if query is called from new DataContext (I’m disposing DataContext in the service but I’m getting Machine from previous DataContext). I use POCOs and XML mapping. Revised: It looks like compiled query is returning result from new data context and it is not using the one that I passed in compiled-query. Therefore I can not reuse returned object and link it to another object obtained from datacontext thru non compiled queries. I’m using unit of work pattern : // First Call Using(new DataContext) { Machine from DataContext.Table == machine from cached query } // Do some work // Second Call is failing Using(new DataContext) { Machine from DataContext.Table <> machine from cached query }

  • Print gif using java on a 4x6" paper

    - by Wienczny
    What is the best way in Java to print a gif given as byte[] or ByteArrayInputStream on a paper with a size of 4x6 inches? This: PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(new MediaSize(4, 6, Size2DSyntax.INCH)); aset.add(new Copies(1)); PrintService[] pservices = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.GIF, aset); DocPrintJob printJob = pservices[0].createPrintJob(); Doc doc = new SimpleDoc(sap.getGraphicImageBytes(), DocFlavor.INPUT_STREAM.GIF, null); printJob.print(doc, aset); does not work because the MediaSize is not a PrintRequestAttribute. This should be almost the same as in Package javax.print Description

  • jQuery fadeOut, replaceWith, animate almost working

    - by Jesse
    I am trying to accomplish the following: 1. On click, have a div with id="fader" fadeout 2. replaceHtml of fader with new html (this new HTML will appear below the fold of the browser) 3. Animate new HTML to slide up to the specified location Step 1 and 2 are working, step 3 is not and I'm stumped as to why. Here's the javascript: $("#fader").fadeOut(1000, function() { $(this).replaceWith('<div id=\"fader\" style=\"margin-top:-500px;width:500px;height:400px;border:1px solid black;\">new div</div>', function() { $("#fader").animate({marginTop: "500px"}); }); }); Any thoughts on why the div won't animate would be greatly appreciated, thanks in advance!
