  • WCF client encrypt message to JAVA WS using username_token with message protection client policy

    - by Alex
    I am trying to create a WCF client APP that is consuming a JAVA WS that uses username_token with message protection client policy. There is a private key that is installed on the server and a public certificate file was exported from the JKS keystore file. I have installed the public key into certificate store via MMC under Personal certificates. I am trying to create a binding that will encrypt the message and pass the username as part of the payload. I have been researching and trying the different configurations for about a day now. I found a similar situation on the msdn forum: http://social.msdn.microsoft.com/Forums/en/wcf/thread/ce4b1bf5-8357-4e15-beb7-2e71b27d7415 This is the configuration that I am using in my app.config <customBinding> <binding name="certbinding"> <security authenticationMode="UserNameOverTransport"> <secureConversationBootstrap /> </security> <httpsTransport requireClientCertificate="true" /> </binding> </customBinding> <endpoint address="https://localhost:8443/ZZZService?wsdl" binding="customBinding" bindingConfiguration="cbinding" contract="XXX.YYYPortType" name="ServiceEndPointCfg" /> And this is the client code that I am using: EndpointAddress endpointAddress = new EndpointAddress(url + "?wsdl"); P6.WCF.Project.ProjectPortTypeClient proxy = new P6.WCF.Project.ProjectPortTypeClient("ServiceEndPointCfg", endpointAddress); proxy.ClientCredentials.UserName.UserName = UserName; proxy.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindByThumbprint, "67 87 ba 28 80 a6 27 f8 01 a6 53 2f 4a 43 3b 47 3e 88 5a c1"); var projects = proxy.ReadProjects(readProjects); This is the .NET CLient error I get: Error Log: Invalid security information. On the Java WS side I trace the log : SEVERE: Encryption is enabled but there is no encrypted key in the request. I traced the SOAP headers and payload and did confirm the encrypted key is not there.

  • Alternative to google map api, so that I can use it on a HTTPS/SSL encrypted website.

    - by Zeeshan Rang
    I did find a solution for this on Google map api page, and I made the following changes as mentioned in it. 1.Use Google Maps API for Flash version 1.9a or later. 2.Add the following to your Flash application before the map is instantiated: Security.allowInsecureDomain("maps.googleapis.com"); Ref:http://code.google.com/apis/maps/faq.html#flash_ssl My code looks like this, after the changes: <mx:TitleWindow verticalAlign="middle" horizontalAlign="center" xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:maps="com.google.maps.*" width="1000" height="600" layout="absolute" backgroundAlpha="0" borderAlpha="0" borderThickness="0" showCloseButton="true" close="PopUpManager.removePopUp(this);"> <mx:VBox width="70%" height="100%" > <maps:Map id="map" key="ABQIAAAA0L1JEoR6rWjh-BBQnLMtMBSVuZ5VlaqlIqiYPFMK_I5M2UTmHhSq_BJxLHiYcTDW9RxSF6HewNY7uA" mapevent_mapready="onMapReady(event)" width="100%" height="100%" /> </mx:VBox> <mx:Script> <![CDATA[ //import flashx.textLayout.formats.Direction; import mx.effects.AddItemAction; //import flashx.textLayout.factory.TruncationOptions; import mx.controls.Alert; import mx.managers.PopUpManager; import mx.rpc.events.ResultEvent; import com.adobe.serialization.json.JSON; import flash.events.Event; import com.google.maps.*; import com.google.maps.overlays.*; import com.google.maps.services.*; import com.google.maps.controls.ZoomControl; import com.google.maps.controls.PositionControl; import com.google.maps.controls.MapTypeControl; import com.google.maps.services.ClientGeocoderOptions; import com.google.maps.LatLng; import com.google.maps.Map; import com.google.maps.MapEvent; import com.google.maps.MapMouseEvent; import com.google.maps.MapType; import com.google.maps.services.ClientGeocoder; import com.google.maps.services.GeocodingEvent; import com.google.maps.overlays.Marker; import com.google.maps.overlays.MarkerOptions; import com.google.maps.InfoWindowOptions; private function onMapReady(event:MapEvent):void { Security.allowInsecureDomain("maps.googleapis.com"); map.setCenter(new LatLng(41.651505,-72.094455), 13, MapType.NORMAL_MAP_TYPE); map.addControl(new ZoomControl()); map.addControl(new PositionControl()); map.addControl(new MapTypeControl()); map.enableScrollWheelZoom(); map.enableContinuousZoom(); } ]]> </mx:Script> </mx:TitleWindow> But i still get the following error using this: The requested URL /mapsapi/publicapi?file=flashapi&url=https%3A%2F%2Fvirtual.c7beta.com%2Findex_cloud.swf&key=ABQIAAAA0L1JEoR6rWjh-BBQnLMtMBTW_Qkp6J0z76Etz3qzo8Hg3HdUQhSnD6lqp53NB0UrBmg5Xm2DlazWqA&v=1.18&flc=xt was not found on this server.

  • TwoWay Binding With ItemsControl

    - by Andrew
    I'm trying to write a user control that has an ItemsControl, the ItemsTemplate of which contains a TextBox that will allow for TwoWay binding. However, I must be making a mistake somewhere in my code, because the binding only appears to work as if Mode=OneWay. This is a pretty simplified excerpt from my project, but it still contains the problem: <UserControl x:Class="ItemsControlTest.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <StackPanel> <ItemsControl ItemsSource="{Binding Path=.}" x:Name="myItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Mode=TwoWay, UpdateSourceTrigger=LostFocus, Path=.}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <Button Click="Button_Click" Content="Click Here To Change Focus From ItemsControl" /> </StackPanel> </Grid> </UserControl> Here's the code behind for the above control: using System; using System.Windows; using System.Windows.Controls; using System.Collections.ObjectModel; namespace ItemsControlTest { /// <summary> /// Interaction logic for UserControl1.xaml /// </summary> public partial class UserControl1 : UserControl { public ObservableCollection<string> MyCollection { get { return (ObservableCollection<string>)GetValue(MyCollectionProperty); } set { SetValue(MyCollectionProperty, value); } } // Using a DependencyProperty as the backing store for MyCollection. This enables animation, styling, binding, etc... public static readonly DependencyProperty MyCollectionProperty = DependencyProperty.Register("MyCollection", typeof(ObservableCollection<string>), typeof(UserControl1), new UIPropertyMetadata(new ObservableCollection<string>())); public UserControl1() { for (int i = 0; i < 6; i++) MyCollection.Add("String " + i.ToString()); InitializeComponent(); myItemsControl.DataContext = this.MyCollection; } private void Button_Click(object sender, RoutedEventArgs e) { // Insert a string after the third element of MyCollection MyCollection.Insert(3, "Inserted Item"); // Display contents of MyCollection in a MessageBox string str = ""; foreach (string s in MyCollection) str += s + Environment.NewLine; MessageBox.Show(str); } } } And finally, here's the xaml for the main window: <Window x:Class="ItemsControlTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:src="clr-namespace:ItemsControlTest" Title="Window1" Height="300" Width="300"> <Grid> <src:UserControl1 /> </Grid> </Window> Well, that's everything. I'm not sure why editing the TextBox.Text properties in the window does not seem to update the source property for the binding in the code behind, namely MyCollection. Clicking on the button pretty much causes the problem to stare me in the face;) Please help me understand where I'm going wrong. Thanx! Andrew

  • JPA thinks I'm deleting a detached object

    - by Steve
    So, I've got a DAO that I used to load and save my domain objects using JPA. I finally managed to get the transaction stuff working (with a bunch of help from the folks here...), now I've got another issue. In my test case, I call my DAO to load a domain object with a given id, check that it got loaded and then call the same DAO to delete the object I just loaded. When I do that I get the following: java.lang.IllegalArgumentException: Removing a detached instance mil.navy.ndms.conops.common.model.impl.jpa.Group#10 at org.hibernate.ejb.event.EJB3DeleteEventListener.performDetachedEntityDeletionCheck(EJB3DeleteEventListener.java:45) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:108) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:74) at org.hibernate.impl.SessionImpl.fireDelete(SessionImpl.java:794) at org.hibernate.impl.SessionImpl.delete(SessionImpl.java:772) at org.hibernate.ejb.AbstractEntityManagerImpl.remove(AbstractEntityManagerImpl.java:253) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:180) at $Proxy27.remove(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao.delete(GroupDao.java:499) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:304) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:106) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy28.delete(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDaoTest.testGroupDaoSave(GroupDaoTest.java:89) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at junit.framework.TestCase.runTest(TestCase.java:164) at junit.framework.TestCase.runBare(TestCase.java:130) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Now given that I'm using the same DAO instance, and I've not changed EntityManagers (unless Spring does so without letting me know), how can this be a detached object? My DAO code looks like this: public class GenericJPADao implements IWebDao, IDao, IDaoUtil { private static Logger logger = Logger.getLogger (GenericJPADao.class); protected Class voClass; @PersistenceContext(unitName = "CONOPS_PU") protected EntityManagerFactory emf; @PersistenceContext(unitName = "CONOPS_PU") protected EntityManager em; public GenericJPADao() { super ( ); ParameterizedType genericSuperclass = (ParameterizedType) getClass ( ).getGenericSuperclass ( ); this.voClass = (Class) genericSuperclass.getActualTypeArguments ( )[1]; } ... public void delete (INTFC modelObj, EntityManager em) { em.remove (modelObj); } @SuppressWarnings("unchecked") public INTFC findById (Long id) { return ((INTFC) em.find (voClass, id)); } } The test case code looks like: IGroup loadedGroup = dao.findById (group.getId ( )); assertNotNull (loadedGroup); assertEquals (group.getId ( ), loadedGroup.getId ( )); dao.delete (loadedGroup); // - This generates the above exception loadedGroup = dao.findById (group.getId ( )); assertNull(loadedGroup); Can anyone tell me what I'm doing wrong here? Thanks

  • Using bindings to control column order in a DataGrid

    - by DanM
    Problem I have a WPF Toolkit DataGrid, and I'd like to be able to switch among several preset column orders. This is an MVVM project, so the column orders are stored in a ViewModel. The problem is, I can't get bindings to work for the DisplayIndex property. No matter what I try, including the sweet method in this Josh Smith tutorial, I get: The DisplayIndex for the DataGridColumn with Header 'ID' is out of range. DisplayIndex must be greater than or equal to 0 and less than Columns.Count. Parameter name: displayIndex. Actual value was -1. Is there any workaround for this? I'm including my test code below. Please let me know if you see any problems with it. ViewModel code public class MainViewModel { public List<Plan> Plans { get; set; } public int IdDisplayIndex { get; set; } public int NameDisplayIndex { get; set; } public int DescriptionDisplayIndex { get; set; } public MainViewModel() { Initialize(); } private void Initialize() { IdDisplayIndex = 1; NameDisplayIndex = 2; DescriptionDisplayIndex = 0; Plans = new List<Plan> { new Plan { Id = 1, Name = "Primary", Description = "Likely to work." }, new Plan { Id = 2, Name = "Plan B", Description = "Backup plan." }, new Plan { Id = 3, Name = "Plan C", Description = "Last resort." } }; } } Plan Class public class Plan { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } Window code - this uses Josh Smith's DataContextSpy <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" xmlns:mwc="http://schemas.microsoft.com/wpf/2008/toolkit" Title="Main Window" Height="300" Width="300"> <Grid> <mwc:DataGrid ItemsSource="{Binding Plans}" AutoGenerateColumns="False"> <mwc:DataGrid.Resources> <local:DataContextSpy x:Key="spy" /> </mwc:DataGrid.Resources> <mwc:DataGrid.Columns> <mwc:DataGridTextColumn Header="ID" Binding="{Binding Id}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.IdDisplayIndex}" /> <mwc:DataGridTextColumn Header="Name" Binding="{Binding Name}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.NameDisplayIndex}" /> <mwc:DataGridTextColumn Header="Description" Binding="{Binding Description}" DisplayIndex="{Binding Source={StaticResource spy}, Path=DataContext.DescriptionDisplayIndex}" /> </mwc:DataGrid.Columns> </mwc:DataGrid> </Grid> </Window> Note: If I just use plain numbers for DisplayIndex, everything works fine, so the problem is definitely with the bindings. Update 5/1/2010 I was just doing a little maintenance on my project, and I noticed that when I ran it, the problem I discuss in this post had returned. I knew that it worked last time I ran it, so I eventually narrowed the problem down to the fact that I had installed a newer version of the WPF Toolkit (Feb '10). When I reverted to the June '09 version, everything worked fine again. So, I'm now doing something I should have done in this first place: I'm including the WPFToolkit.dll that works in my solution folder and checking it into version control. It's unfortunate, though, that the newer toolkit has a breaking change.

  • Outlook Addin: DispEventAdvise exception.

    I want to creating an addin that captures when a {contact, calendar, task, note} is {created, edited, removed}.

  • C# and Metadata File Errors

    Hi All I've created my own little c# compiler using the tutorial on MSDN, and it's not working properly. I get a few errors, then I fix them, then I get new, different errors, then I fix them, etc etc. The latest error is really confusing me. --------------------------- --------------------------- Line number: 0, Error number: CS0006, 'Metadata file 'System.Linq.dll' could not be found; --------------------------- OK --------------------------- I do not know what this means. Can somebody please explain what's going on here? Here is my code. MY SAMPLE C# COMPILER CODE: using System; namespace JTM { public class CSCompiler { protected string ot, rt, ss, es; protected bool rg, cg; public string Compile(String se, String fe, String[] rdas, String[] fs, Boolean rn) { System.CodeDom.Compiler.CodeDomProvider CODEPROV = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp"); ot = fe; System.CodeDom.Compiler.CompilerParameters PARAMS = new System.CodeDom.Compiler.CompilerParameters(); // Ensure the compiler generates an EXE file, not a DLL. PARAMS.GenerateExecutable = true; PARAMS.OutputAssembly = ot; foreach (String ay in rdas) { if (ay.Contains(".dll")) PARAMS.ReferencedAssemblies.Add(ay); else { string refd = ay; refd = refd + ".dll"; PARAMS.ReferencedAssemblies.Add(refd); } } System.CodeDom.Compiler.CompilerResults rs = CODEPROV.CompileAssemblyFromFile(PARAMS, fs); if (rs.Errors.Count > 0) { foreach (System.CodeDom.Compiler.CompilerError COMERR in rs.Errors) { es = es + "Line number: " + COMERR.Line + ", Error number: " + COMERR.ErrorNumber + ", '" + COMERR.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { // Compilation succeeded. es = "Compilation Succeeded."; if (rn) System.Diagnostics.Process.Start(ot); } return es; } } } ... And here is the app that passes the code to the above class: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string[] f = { "Form1.cs", "Form1.Designer.cs", "Program.cs" }; string[] ra = { "System.dll", "System.Windows.Forms.dll", "System.Data.dll", "System.Drawing.dll", "System.Deployment.dll", "System.Xml.dll", "System.Linq.dll" }; JTS.CSCompiler CSC = new JTS.CSCompiler(); MessageBox.Show(CSC.Compile( textBox1.Text, @"Test Application.exe", ra, f, false)); } } } So, as you can see, all the using directives are there. I don't know what this error means. Any help at all is much appreciated. Thank you

  • wpf window refresh works at first, then stops

    - by mcl
    I've got a routine that grabs a list of all images in a directory, then runs an MD5 digest on all of them. Since this takes a while to do, I pop up a window with a progress bar. The progress bar is updated by a lambda that I pass in to the long-running routine. The first problem was that the progress window was never updated (which is normal in WPF I guess). Since WPF lacks a Refresh() command I fixed this with a call to Dispatcher.Invoke(). Now the progress bar is updated for a while, then the window stops being updated. The long-running work does eventually finish and the windows go back to normal. I have already tried a BackgroundWorker and quickly became frustrated by a threading issue related to an event triggered by the long-running process. So if that's really the best solution and I just need to learn the paradigm better, please say so. But I'd be really much happier with the approach I've got here, except that it stops updating after a bit (for example, in a folder with 1000 files, it might update for 50-100 files, then "hang"). The UI does not need to be responsive during this activity, except to report on progress. Anyway, here's the code. First the progress window itself: public partial class ProgressWindow : Window { public ProgressWindow(string title, string supertext, string subtext) { InitializeComponent(); this.Title = title; this.SuperText.Text = supertext; this.SubText.Text = subtext; } internal void UpdateProgress(int count, int total) { this.ProgressBar.Maximum = Convert.ToDouble(total); this.ProgressBar.Value = Convert.ToDouble(count); this.SubText.Text = String.Format("{0} of {1} finished", count, total); this.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate); } private static Action EmptyDelegate = delegate() { }; } <Window x:Class="Pixort.ProgressWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Pixort Progress" Height="128" Width="256" WindowStartupLocation="CenterOwner" WindowStyle="SingleBorderWindow" ResizeMode="NoResize"> <DockPanel> <TextBlock DockPanel.Dock="Top" x:Name="SuperText" TextAlignment="Left" Padding="6"></TextBlock> <TextBlock DockPanel.Dock="Bottom" x:Name="SubText" TextAlignment="Right" Padding="6"></TextBlock> <ProgressBar x:Name="ProgressBar" Height="24" Margin="6"/> </DockPanel> </Window> The long running method (in Gallery.cs): public void ImportFolder(string folderPath, Action<int, int> progressUpdate) { string[] files = this.FileIO.GetFiles(folderPath); for (int i = 0; i < files.Length; i++) { // do stuff with the file if (null != progressUpdate) { progressUpdate.Invoke(i + 1, files.Length); } } } Which is called thusly: ProgressWindow progress = new ProgressWindow("Import Folder Progress", String.Format("Importing {0}", folder), String.Empty); progress.Show(); this.Gallery.ImportFolder(folder, ((c, t) => progress.UpdateProgress(c, t))); progress.Close();

  • What git branching models actually work - the final question

    - by UncleCJ
    In our company we have successfully deployed git and we are currently using a simple trunk/release/hotfixes branching model. However, this has it's problems, I have some key issues of confusion in the community which would be awesome to have answered here. Maybe my hopes for an Alexander stroke are too great, quite possibly I'll decompose this question into more manageable issues, but here's my first shot. Workflows / branching models - below are the three main descriptions of this I have seen, but they are partially contradicting each other or don't go far enough to sort out the subsequent issues we've run into (as described below). Thus our team so far defaults to not so great solutions. Are you doing something better? gitworkflows(7) Manual Page (nvie) A successful Git branching model (reinh) A Git Workflow for Agile Teams Merging vs rebasing (tangled vs sequential history) - the bids on this are as confusing as it gets. Should one pull --rebase or wait with merging back to the mainline until your task is finished? Personally I lean towards merging since this preserves a visual illustration of on which base a task was started and finished, and I even prefer merge --no-ff for this purpose. It has other drawbacks however. Also many haven't realized the useful property of merging - that it isn't commutative (merging a topic branch into master does not mean merging master into the topic branch). I am looking for a natural workflow - sometimes mistakes happen because our procedures don't capture a specific situation with simple rules. For example a fix needed for earlier releases should of course be based sufficiently downstream to be possible to merge upstream into all branches necessary (is the usage of these terms clear enough?). However it happens that a fix makes it into the master before the developer realizes it should have been placed further downstream, and if that is already pushed (even worse, merged or something based on it) then the option remaining is cherry-picking, with it's associated perils... What simple rules like such do you use? Also in this is included the awkwardness of one topic branch necessarily excluding other topic branches (assuming they are branched from a common baseline). Developers don't want to finish a feature to start another one feeling like the code they just wrote is not there anymore How to avoid creating merge conflicts (due to cherry-pick)? What seems like a sure way to create a merge conflict is to cherry-pick between branches, they can never be merged again? Would applying the same commit in revert (how to do this?) in either branch possibly solve this situation? This is one reason I do not dare to push for a largely merge-based workflow. How to decompose into topical branches? - We realize that it would be awesome to assemble a finished integration from topic branches, but often work by our developers is not clearly defined (sometimes as simple as "poking around") and if some code has already gone into a "misc" topic, it can not be taken out of there again, according to the question above? How do you work with defining/approving/graduating/releasing your topic branches? Proper procedures like code review and graduating would of course be lovely, but we simply cannot keep things untangled enough to manage this - any suggestions? integration branches, illustration please? Vote and comment as much as you'd like, I'll try to keep the issue page clear and informative enough. Thanks! Below is a list of related topics on stackoverflow I have checked out: What are some good strategies to allow deployed applications to be hotfixable? Workflow description for git usage for in-house development Git workflow for corporate Linux kernel development How do you maintain development code and production code?

  • overloaded stream insertion operator with a vector

    - by Julz
    hi, i'm trying to write an overloaded stream insertion operator for a class who's only member is a vector. i dont really know what i'm doing. (lets make that clear) it's a vector of "Points" which is a struct containing two doubles. i figure what i want is to insert user input (a bunch of doubles) into a stream that i then send to a modifier method? i keep working off other stream insertion examples such as... std::ostream& operator<< (std::ostream& o, Fred const& fred) { return o << fred.i_; } but when i try a similar..... istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr.vertices; return inStream; } i get an error "no match for operator etc etc. if i leave off the .vertices it compiles but i figure it's not right? (vertices is the name of my vector ) and even if it is right, i dont actually know what syntax to use in my driver to use it? also not %100 on what my modifier method needs to look like. here's my Polygon class //header #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); public: //Constructor Polygon(const Point &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return (int) vertices.capacity();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; #endif //Body using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const Point &theVerts) { vertices.push_back (theVerts); } //Copy Constructor Polygon::Polygon(const Polygon &polyCopy) { vertices = polyCopy.vertices; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } any help greatly appreciated, sorry to be so vague, a lecturer has just kind of given us a brief example of stream insertion then left us on our own thanks. oh i realise there are probably many other problems that need fixing

  • FMOD.net streaming, callback and exinfo parameters

    - by Tesserex
    I posted a question on gamedev about how to play nsf files (NES console music) in FMOD. It didn't get any results, but since then I made some progress. I decided that the easiest method was just to compile an existing player into a dll and then call it from C# to populate my buffer. The problem now is getting it to sound right, and making sure all my paremeters are correct. Here are the facts so far: The nsf dll is dealing with shorts, so the data is PCM16. The sample nsf I'm using has a playback rate of 60 Hz. Just for playing around now, I'm using a frequency of 48000. Based on 2 and 3, the dll calculates a necessary buffer size of 48000 / 60hz = 800. This means it will render 800 shorts worth of buffer for every simulated NES frame. I've so far got my C# code to play the nsf, at the correct pitch and tempo, but it's very grainy / fuzzy, which I'm attributing to the fact that the FMOD read callback is giving a data length of 1600, whereas I should be expecting 800. I've tried playing around with all the numbers and it either crashes, or the music changes pitch, tempo, or both. Here's some of my C# code: uint channels = 1, frequency = 48000; FMOD.MODE mode = (FMOD.MODE.DEFAULT | FMOD.MODE.OPENUSER | FMOD.MODE.LOOP_NORMAL); FMOD.Sound sound = new FMOD.Sound(); FMOD.CREATESOUNDEXINFO ex = new FMOD.CREATESOUNDEXINFO(); ex.cbsize = Marshal.SizeOf(ex); ex.fileoffset = 0; ex.format = FMOD.SOUND_FORMAT.PCM16; // does this even matter? It doesn't change my results as long as it's long enough for one update ex.length = frequency; ex.numchannels = (int)channels; ex.defaultfrequency = (int)frequency; ex.pcmreadcallback = pcmreadcallback; ex.dlsname = null; // eventually I will calculate this with frequency / nsf hz, but I'm just testing for now ex.decodebuffersize = 800; // from the dll load_nsf_file("file.nsf", 8, (int)frequency); // 8 is the track number to play var result = system.createSound( (string)null, (mode | FMOD.MODE.CREATESTREAM), ref ex, ref sound); channel = new FMOD.Channel(); result = system.playSound(FMOD.CHANNELINDEX.FREE, sound, false, ref channel); private FMOD.RESULT PCMREADCALLBACK(IntPtr soundraw, IntPtr data, uint datalen) { // from the dll process_buffer(data, (int)800); // if I use datalen, it usually crashes (I can't get datalen to = 800 safely) return FMOD.RESULT.OK; } So here are some of my questions: What is the relationship between exinfo.decodebuffersize, frequency, and the datalen parameter of the read callback? With this code sample, it's coming in as 3200. I don't know where that factor of 4 between it and the decodebuffersize comes from. Is datalen in the callback referring to number of bytes, or shorts? The process_buffer function takes a short array and its length. I would expect fmod is talking about shorts as well because I told it PCM16. Maybe my playback quality is bad for some totally different reason. If so I have no idea where to begin solving that. Any ideas there?

  • Passing integer lists in a sql query, best practices

    - by Artiom Chilaru
    I'm currently looking at ways to pass lists of integers in a SQL query, and try to decide which of them is best in which situation, what are the benefots of each, and what are the pitfalls, what should be avoided :) Right now I know of 3 ways that we currently use in our application. 1) Table valued parameter: Create a new Table Valued Parameter in sql server: CREATE TYPE [dbo].[TVP_INT] AS TABLE( [ID] [int] NOT NULL ) Then run the query against it: using (var conn = new SqlConnection(DataContext.GetDefaultConnectionString)) { var comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = @" UPDATE DA SET [tsLastImportAttempt] = CURRENT_TIMESTAMP FROM [Account] DA JOIN @values IDs ON DA.ID = IDs.ID"; comm.Parameters.Add(new SqlParameter("values", downloadResults.Select(d => d.ID).ToDataTable()) { TypeName = "TVP_INT" }); conn.Open(); comm.ExecuteScalar(); } The major disadvantages of this method is the fact that Linq doesn't support table valued params (if you create an SP with a TVP param, linq won't be able to run it) :( 2) Convert the list to Binary and use it in Linq! This is a bit better.. Create an SP, and you can run it within linq :) To do this, the SP will have an IMAGE parameter, and we'll be using a user defined function (udf) to convert this to a table.. We currently have implementations of this function written in C++ and in assembly, both have pretty much the same performance :) Basically, each integer is represented by 4 bytes, and passed to the SP. In .NET we have an extension method that convers an IEnumerable to a byte array The extension method: public static Byte[] ToBinary(this IEnumerable intList) { return ToBinaryEnum(intList).ToArray(); } private static IEnumerable<Byte> ToBinaryEnum(IEnumerable<Int32> intList) { IEnumerator<Int32> marker = intList.GetEnumerator(); while (marker.MoveNext()) { Byte[] result = BitConverter.GetBytes(marker.Current); Array.Reverse(result); foreach (byte b in result) yield return b; } } The SP: CREATE PROCEDURE [Accounts-UpdateImportAttempts] @values IMAGE AS BEGIN UPDATE DA SET [tsLastImportAttempt] = CURRENT_TIMESTAMP FROM [Account] DA JOIN dbo.udfIntegerArray(@values, 4) IDs ON DA.ID = IDs.Value4 END And we can use it by running the SP directly, or in any linq query we need using (var db = new DataContext()) { db.Accounts_UpdateImportAttempts(downloadResults.Select(d => d.ID).ToBinary()); // or var accounts = db.Accounts .Where(a => db.udfIntegerArray(downloadResults.Select(d => d.ID).ToBinary(), 4) .Select(i => i.Value4) .Contains(a.ID)); } This method has the benefit of using compiled queries in linq (which will have the same sql definition, and query plan, so will also be cached), and can be used in SPs as well. Both these methods are theoretically unlimited, so you can pass millions of ints at a time :) 3) The simple linq .Contains() It's a more simple approach, and is perfect in simple scenarios. But is of course limited by this. using (var db = new DataContext()) { var accounts = db.Accounts .Where(a => downloadResults.Select(d => d.ID).Contains(a.ID)); } The biggest drawback of this method is that each integer in the downloadResults variable will be passed as a separate int.. In this case, the query is limited by sql (max allowed parameters in a sql query, which is a couple of thousand, if I remember right). So I'd like to ask.. What do you think is the best of these, and what other methods and approaches have I missed?

  • .NET 4.0 Dynamic object used statically?

    - by Kevin Won
    I've gotten quite sick of XML configuration files in .NET and want to replace them with a format that is more sane. Therefore, I'm writing a config file parser for C# applications that will take a custom config file format, parse it, and create a Python source string that I can then execute in C# and use as a static object (yes that's right--I want a static (not the static type dyanamic) object in the end). Here's an example of what my config file looks like: // my custom config file format GlobalName: ExampleApp Properties { ExternalServiceTimeout: "120" } Python { // this allows for straight python code to be added to handle custom config def MyCustomPython: return "cool" } Using ANTLR I've created a Lexer/Parser that will convert this format to a Python script. So assume I have that all right and can take the .config above and run my Lexer/Parser on it to get a Python script out the back (this has the added benefit of giving me a validation tool for my config). By running the resultant script in C# // simplified example of getting the dynamic python object in C# // (not how I really do it) ScriptRuntime py = Python.CreateRuntime(); dynamic conf = py.UseFile("conftest.py"); dynamic t = conf.GetConfTest("test"); I can get a dynamic object that has my configuration settings. I can now get my config file settings in C# by invoking a dynamic method on that object: //C# calling a method on the dynamic python object var timeout = t.GetProperty("ExternalServiceTimeout"); //the config also allows for straight Python scripting (via the Python block) var special = t.MyCustonPython(); of course, I have no type safety here and no intellisense support. I have a dynamic representation of my config file, but I want a static one. I know what my Python object's type is--it is actually newing up in instance of a C# class. But since it's happening in python, it's type is not the C# type, but dynamic instead. What I want to do is then cast the object back to the C# type that I know the object is: // doesn't work--can't cast a dynamic to a static type (nulls out) IConfigSettings staticTypeConfig = t as IConfigSettings Is there any way to figure out how to cast the object to the static type? I'm rather doubtful that there is... so doubtful that I took another approach of which I'm not entirely sure about. I'm wondering if someone has a better way... So here's my current tactic: since I know the type of the python object, I am creating a C# wrapper class: public class ConfigSettings : IConfigSettings that takes in a dynamic object in the ctor: public ConfigSettings(dynamic settings) { this.DynamicProxy = settings; } public dynamic DynamicProxy { get; private set; } Now I have a reference to the Python dynamic object of which I know the type. So I can then just put wrappers around the Python methods that I know are there: // wrapper access to the underlying dynamic object // this makes my dynamic object appear 'static' public string GetSetting(string key) { return this.DynamicProxy.GetProperty(key).ToString(); } Now the dynamic object is accessed through this static proxy and thus can obviously be passed around in the static C# world via interface, etc: // dependency inject the dynamic object around IBusinessLogic logic = new BusinessLogic(IConfigSettings config); This solution has the benefits of all the static typing stuff we know and love while at the same time giving me the option of 'bailing out' to dynamic too: // the DynamicProxy property give direct access to the dynamic object var result = config.DynamicProxy.MyCustomPython(); but, man, this seems rather convoluted way of getting to an object that is a static type in the first place! Since the whole dynamic/static interaction world is new to me, I'm really questioning if my solution is optimal or if I'm missing something (i.e. some way of casting that dynamic object to a known static type) about how to bridge the chasm between these two universes.

  • AppDomain dependencies across directories

    - by strager
    I am creating a plugin system and I am creating one AppDomain per plugin. Each plugin has its own directory with its main assemblies and references. The main assemblies will be loaded by my plugin loader, in addition to my interface assemblies (so the plugin can interact with the application). Creating the AppDomain: this.appDomain = AppDomain.CreateDomain("AppDomain", null, new AppDomainSetup { ApplicationBase = pluginPath, PrivateBinPath = pluginPath, }); Loading the assemblies: this.appDomain.Load(myInterfaceAssembly.GetName(true)); var assemblies = new List<Assembly>(); foreach (var assemblyName in this.assemblyNames) { assemblies.Add(this.appDomain.Load(assemblyName)); } The format of assemblyName is the assembly's filename without ".dll". The problem is that AppDomain.Load(assemblyName) throws an exception: Could not load file or assembly '[[assemblyName]], Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. All of the dependencies of [[assemblyName]] are: Inside the directory pluginPath, The myInterfaceAssembly which is already loaded, or In the GAC (e.g. mscorelib). Clearly I'm not doing something right. I have tried: Creating an object using this.appDomain.CreateInstanceAndUnwrap inheriting from MarshalByRefObject with a LoadAssembly method to load the assembly. I get an exception saying that the current assembly (containing the proxy class) could not be loaded (file not found, as above), even if I manually call this.appDomain.Load(Assembly.GetExecutingAssembly().GetName(true)). Attaching an AssemblyResolve handler to this.appDomain. I'm met with the same exception as in (1), and manually loading doesn't help. Recursively loading assemblies by loading their dependencies into this.appDomain first. This doesn't work, but I doubt my code is correct: private static void LoadAssemblyInto(AssemblyName assemblyName, AppDomain appDomain) { var assembly = Assembly.Load(assemblyName); foreach (var referenceName in assembly.GetReferencedAssemblies()) { if (!referenceName.FullName.StartsWith("MyProject")) { continue; } var loadedAssemblies = appDomain.GetAssemblies(); if (loadedAssemblies.Any((asm) => asm.FullName == referenceName.FullName)) { continue; } LoadAssemblyInto(referenceName, appDomain); } appDomain.Load(assembly.GetName(true)); } How can I load my plugin assembly with its dependencies in that plugin's directory while also loading some assemblies in the current directory? Note: The assemblies a plugin may (probably will) reference are already loaded in the current domain. This can be shared across domains (performance benefit? simplicity?) if required.

  • Jumbled byte array after using TcpClient and TcpListener

    - by Dylan
    I want to use the TcpClient and TcpListener to send an mp3 file over a network. I implemented a solution of this using sockets, but there were some issues so I am investigating a new/better way to send a file. I create a byte array which looks like this: length_of_filename|filename|file This should then be transmitted using the above mentioned classes, yet on the server side the byte array I read is completely messed up and I'm not sure why. The method I use to send: public static void Send(String filePath) { try { IPEndPoint endPoint = new IPEndPoint(Settings.IpAddress, Settings.Port + 1); Byte[] fileData = File.ReadAllBytes(filePath); FileInfo fi = new FileInfo(filePath); List<byte> dataToSend = new List<byte>(); dataToSend.AddRange(BitConverter.GetBytes(Encoding.Unicode.GetByteCount(fi.Name))); // length of filename dataToSend.AddRange(Encoding.Unicode.GetBytes(fi.Name)); // filename dataToSend.AddRange(fileData); // file binary data using (TcpClient client = new TcpClient()) { client.Connect(Settings.IpAddress, Settings.Port + 1); // Get a client stream for reading and writing. using (NetworkStream stream = client.GetStream()) { // server is ready stream.Write(dataToSend.ToArray(), 0, dataToSend.ToArray().Length); } } } catch (ArgumentNullException e) { Debug.WriteLine(e); } catch (SocketException e) { Debug.WriteLine(e); } } } Then on the server side it looks as follows: private void Listen() { TcpListener server = null; try { // Setup the TcpListener Int32 port = Settings.Port + 1; IPAddress localAddr = IPAddress.Parse("127.0.0.1"); // TcpListener server = new TcpListener(port); server = new TcpListener(localAddr, port); // Start listening for client requests. server.Start(); // Buffer for reading data Byte[] bytes = new Byte[1024]; List<byte> data; // Enter the listening loop. while (true) { Debug.WriteLine("Waiting for a connection... "); string filePath = string.Empty; // Perform a blocking call to accept requests. // You could also user server.AcceptSocket() here. using (TcpClient client = server.AcceptTcpClient()) { Debug.WriteLine("Connected to client!"); data = new List<byte>(); // Get a stream object for reading and writing using (NetworkStream stream = client.GetStream()) { // Loop to receive all the data sent by the client. while ((stream.Read(bytes, 0, bytes.Length)) != 0) { data.AddRange(bytes); } } } int fileNameLength = BitConverter.ToInt32(data.ToArray(), 0); filePath = Encoding.Unicode.GetString(data.ToArray(), 4, fileNameLength); var binary = data.GetRange(4 + fileNameLength, data.Count - 4 - fileNameLength); Debug.WriteLine("File successfully downloaded!"); // write it to disk using (BinaryWriter writer = new BinaryWriter(File.Open(filePath, FileMode.Append))) { writer.Write(binary.ToArray(), 0, binary.Count); } } } catch (Exception ex) { Debug.WriteLine(ex); } finally { // Stop listening for new clients. server.Stop(); } } Can anyone see something that I am missing/doing wrong?

  • Real-time graphing in Java

    - by thodinc
    I have an application which updates a variable about between 5 to 50 times a second and I am looking for some way of drawing a continuous XY plot of this change in real-time. Though JFreeChart is not recommended for such a high update rate, many users still say that it works for them. I've tried using this demo and modified it to display a random variable, but it seems to use up 100% CPU usage all the time. Even if I ignore that, I do not want to be restricted to JFreeChart's ui class for constructing forms (though I'm not sure what its capabilities are exactly). Would it be possible to integrate it with Java's "forms" and drop-down menus? (as are available in VB) Otherwise, are there any alternatives I could look into? EDIT: I'm new to Swing, so I've put together a code just to test the functionality of JFreeChart with it (while avoiding the use of the ApplicationFrame class of JFree since I'm not sure how that will work with Swing's combo boxes and buttons). Right now, the graph is being updated immediately and CPU usage is high. Would it be possible to buffer the value with new Millisecond() and update it maybe twice a second? Also, can I add other components to the rest of the JFrame without disrupting JFreeChart? How would I do that? frame.getContentPane().add(new Button("Click")) seems to overwrite the graph. package graphtest; import java.util.Random; import javax.swing.JFrame; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.plot.XYPlot; import org.jfree.data.time.Millisecond; import org.jfree.data.time.TimeSeries; import org.jfree.data.time.TimeSeriesCollection; public class Main { static TimeSeries ts = new TimeSeries("data", Millisecond.class); public static void main(String[] args) throws InterruptedException { gen myGen = new gen(); new Thread(myGen).start(); TimeSeriesCollection dataset = new TimeSeriesCollection(ts); JFreeChart chart = ChartFactory.createTimeSeriesChart( "GraphTest", "Time", "Value", dataset, true, true, false ); final XYPlot plot = chart.getXYPlot(); ValueAxis axis = plot.getDomainAxis(); axis.setAutoRange(true); axis.setFixedAutoRange(60000.0); JFrame frame = new JFrame("GraphTest"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); ChartPanel label = new ChartPanel(chart); frame.getContentPane().add(label); //Suppose I add combo boxes and buttons here later frame.pack(); frame.setVisible(true); } static class gen implements Runnable { private Random randGen = new Random(); public void run() { while(true) { int num = randGen.nextInt(1000); System.out.println(num); ts.addOrUpdate(new Millisecond(), num); try { Thread.sleep(20); } catch (InterruptedException ex) { System.out.println(ex); } } } } }

  • How do you traverse and store XML in Blackberry Java app?

    - by Greg
    I'm having a problem accessing the contents of an XML document. My goal is this: Take an XML source and parse it into a fair equivalent of an associative array, then store it as a persistable object. the xml is pretty simple: <root> <element> <category_id>1</category_id> <name>Cars</name> </element> <element> <category_id>2</category_id> <name>Boats</name> </element> </root> Basic java class below. I'm pretty much just calling save(xml) after http response above. Yes, the xml is properly formatted. import java.io.IOException; import java.util.Hashtable; import org.w3c.dom.Document; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import java.util.Vector; import net.rim.device.api.system.PersistentObject; import net.rim.device.api.system.PersistentStore; import net.rim.device.api.xml.parsers.DocumentBuilder; import net.rim.device.api.xml.parsers.DocumentBuilderFactory; public class database{ private static PersistentObject storeVenue; static final long key = 0x2ba5f8081f7ef332L; public Hashtable hashtable; public Vector venue_list; String _node,_element; public database() { storeVenue = PersistentStore.getPersistentObject(key); } public void save(Document xml) { venue_list = new Vector(); storeVenue.setContents(venue_list); Hashtable categories = new Hashtable(); try{ DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory. newInstance(); DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); docBuilder.isValidating(); xml.getDocumentElement ().normalize (); NodeList list=xml.getElementsByTagName("*"); _node=new String(); _element = new String(); for (int i=0;i<list.getLength();i++){ Node value=list.item(i).getChildNodes().item(0); _node=list.item(i).getNodeName(); _element=value.getNodeValue(); categories.put(_element, _node); } } catch (Exception e){ System.out.println(e.toString()); } venue_list.addElement(categories); storeVenue.commit(); } The code above is the work in progress, and is most likely heavily flawed. However, I have been at this for days now. I can never seem to get all child nodes, or the name / value pair. When I print out the vector as a string, I usually end up with results like this: [{ = root, = element}] and that's it. No "category_id", no "name" Ideally, I would end up with something like [{1 = cars, 2 = boats}] Any help is appreciated. Thanks

  • Need help with BOOST_FOREACH/compiler bug

    - by Jacek Lawrynowicz
    I know that boost or compiler should be last to blame, but I can't see another explanation here. I'm using msvc 2008 SP1 and boost 1.43. In the following code snippet execution never leaves third BOOST_FOREACH loop typedef Graph<unsigned, unsigned>::VertexIterator Iter; Graph<unsigned, unsigned> g; g.createVertex(0x66); // works fine Iter it = g.getVertices().first, end = g.getVertices().second; for(; it != end; ++it) ; // fine std::pair<Iter, Iter> p = g.getVertices(); BOOST_FOREACH(unsigned handle, p) ; // fine unsigned vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; // oops, infinite loop vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) vertex_count++; // ... last block repeated 7 times Iterator code: class Iterator : public boost::iterator_facade<Iterator, unsigned const, boost::bidirectional_traversal_tag> { public: Iterator() : list(NULL), handle(INVALID_ELEMENT_HANDLE) {} explicit Iterator(const VectorElementsList &list, unsigned handle = INVALID_ELEMENT_HANDLE) : list(&list), handle(handle) {} friend std::ostream& operator<<(std::ostream &s, const Iterator &it) { s << "[list: " << it.list <<", handle: " << it.handle << "]"; return s; } private: friend class boost::iterator_core_access; void increment() { handle = list->getNext(handle); } void decrement() { handle = list->getPrev(handle); } unsigned const& dereference() const { return handle; } bool equal(Iterator const& other) const { return handle == other.handle && list == other.list; } const VectorElementsList<T> *list; unsigned handle; }; Some ASM fun: vertex_count = 0; BOOST_FOREACH(unsigned handle, g.getVertices()) // initialization 013E1369 mov edi,dword ptr [___defaultmatherr+8 (13E5034h)] // end iterator handle: 0xFFFFFFFF 013E136F mov ebp,dword ptr [esp+0ACh] // begin iterator handle: 0x0 013E1376 lea esi,[esp+0A8h] // begin iterator list pointer 013E137D mov ebx,esi 013E137F nop // forever loop begin 013E1380 cmp ebp,edi 013E1382 jne main+238h (13E1388h) 013E1384 cmp ebx,esi 013E1386 je main+244h (13E1394h) 013E1388 lea eax,[esp+18h] 013E138C push eax // here iterator is incremented in ram 013E138D call boost::iterator_facade<detail::VectorElementsList<Graph<unsigned int,unsigned int>::VertexWrapper>::Iterator,unsigned int const ,boost::bidirectional_traversal_tag,unsigned int const &,int>::operator++ (13E18E0h) 013E1392 jmp main+230h (13E1380h) vertex_count++; // forever loop end It's easy to see that iterator handle is cached in EBP and it never gets incremented despite of a call to iterator operator++() function. I've replaced Itarator implmentation with one deriving from std::iterator and the issue persisted, so this is not iterator_facade fault. This problem exists only on msvc 2008 SP1 x86 and amd64 release builds. Debug builds on msvc 2008 and debug/release builds on msvc 2010 and gcc 4.4 (linux) works fine. Furthermore the BOOST_FOREACH block must be repeaded exacly 10 times. If it's repeaded 9 times, it's all OK. I guess that due to BOOST_FOREACH use of template trickery (const auto_any), compiler assumes that iterator handle is constant and never reads its real value again. I would be very happy to hear that my code is wrong, correct it and move on with BOOST_FOREACH, which I'm very found of (as opposed to BOOST_FOREVER :). May be related to: http://stackoverflow.com/questions/1275852/why-does-boost-foreach-not-work-sometimes-with-c-strings

  • Netbeans platform projects - problems with wrapped jar files that have dependencies

    - by I82Much
    For starters, this question is not so much about programming in the NetBeans IDE as developing a NetBeans project (e.g. using the NetBeans Platform framework). I am attempting to use the BeanUtils library to introspect my domain models and provide the properties to display in a property sheet. Sample code: public class MyNode extends AbstractNode implements PropertyChangeListener { private static final PropertyUtilsBean bean = new PropertyUtilsBean(); // snip protected Sheet createSheet() { Sheet sheet = Sheet.createDefault(); Sheet.Set set = Sheet.createPropertiesSet(); APIObject obj = getLookup().lookup (APIObject.class); PropertyDescriptor[] descriptors = bean.getPropertyDescriptors(obj); for (PropertyDescriptor d : descriptors) { Method readMethod = d.getReadMethod(); Method writeMethod = d.getWriteMethod(); Class valueType = d.getClass(); Property p = new PropertySupport.Reflection(obj, valueType, readMethod, writeMethod); set.put(p); } sheet.put(set); return sheet; } I have created a wrapper module around commons-beanutils-1.8.3.jar, and added a dependency on the module in my module containing the above code. Everything compiles fine. When I attempt to run the program and open the property sheet view (i.e.. the above code actually gets run), I get the following error: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:259) Caused: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory starting from ModuleCL@64e48e45[org.apache.commons.beanutils] with possible defining loaders [ModuleCL@75da931b[org.netbeans.libs.commons_logging]] and declared parents [] at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:261) at java.lang.ClassLoader.loadClass(ClassLoader.java:254) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:399) Caused: java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.commons.beanutils.PropertyUtilsBean.<init>(PropertyUtilsBean.java:132) at org.myorg.myeditor.MyNode.<clinit>(MyNode.java:35) at org.myorg.myeditor.MyEditor.<init>(MyEditor.java:33) at org.myorg.myeditor.OpenEditorAction.actionPerformed(OpenEditorAction.java:13) at org.openide.awt.AlwaysEnabledAction$1.run(AlwaysEnabledAction.java:139) at org.netbeans.modules.openide.util.ActionsBridge.implPerformAction(ActionsBridge.java:83) at org.netbeans.modules.openide.util.ActionsBridge.doPerformAction(ActionsBridge.java:67) at org.openide.awt.AlwaysEnabledAction.actionPerformed(AlwaysEnabledAction.java:142) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2351) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:387) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:242) at javax.swing.AbstractButton.doClick(AbstractButton.java:389) at com.apple.laf.ScreenMenuItem.actionPerformed(ScreenMenuItem.java:95) at java.awt.MenuItem.processActionEvent(MenuItem.java:627) at java.awt.MenuItem.processEvent(MenuItem.java:586) at java.awt.MenuComponent.dispatchEventImpl(MenuComponent.java:317) at java.awt.MenuComponent.dispatchEvent(MenuComponent.java:305) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:638) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:296) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:196) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:188) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) I understand that beanutils is using the commons-logging component. I have tried adding the commons-logging component in two different ways (creating a wrapper library around the commons-logging library, and putting a dependency on the Commons Logging Integration library). Neither solves the problem. I noticed that the same problem occurs with other wrapped libraries; if they themselves have external dependencies, the ClassNotFoundExceptions propagate like mad, even if I've wrapped the jars of the libraries they require and added them as dependencies to the original wrapped library module. Pictorially: I'm at my wits end here. I noticed similar problems while googling: Is there a known bug on NB Module dependency Same issue I'm facing but when wrapping a different jar NetBeans stance on this - none of the 3 apply to me. None conclusively help me. Thank you, Nick

    Hi Team, I am just trying with various WCF(in .Net 3.0) scenarios. I am using self hosting. I am getting an exception as "Service 'MyServiceLibrary.NameDecorator' has zero application (non-infrastructure) endpoints.
