  • Implement JNI listener.

    - by G B
    I have the following code in a c++ "listener class" (more or less), which calls some function of a Java object. I suspect there's a memory leak: JNIEnv *env = NULL; vm_->AttachCurrentThread(&env, NULL); const jclass cls = env->FindClass(...); const jmethodID meth = env->GetMethodID(...); const jobject obj = env->NewObject(cls, meth, ...); [ more code ] env->DeleteLocalRef(obj); My question is: should I also release the local reference of cls and meth? JNI Documentation isn't very clear about it.

  • Collision Detection - Java - Rectangle

    - by Trizicus
    I would like to know if this is a good idea that conforms to best practices that does not lead to obscenely confusing code or major performance hit(s): Make my own Collision detection class that extends Rectangle class. Then when instantiating that object doing something such as Collision col = new Rectangle(); <- Should I do that or is that something that should be avoided? I am aware that I 'can' but should I? I want to extend Rectangle class because of the contains() and intersects() methods; should I be doing that or should I be doing something else for 2D collision detection in Java?

  • Error while using PowerMockito.whenNew()

    - by Ankush
    I am using PowerMockito(1.3.6) with Mockito(1.8.3) and Junit(4.7) for testing. I am quite stuck on an error: [junit] Testcase: testNextPNRFromQueueHappyPath(com.orbitz.galileo.host.robot.GalpoQueueConnectionTest): Caused an ERROR [junit] org/mockito/internal/IMockHandler [junit] java.lang.NoClassDefFoundError: org/mockito/internal/IMockHandler [junit] at org.powermock.api.mockito.internal.expectation.DefaultConstructorExpectationSetup.createNewSubsituteMock(DefaultConstructorExpectationSetup.java:80) [junit] at org.powermock.api.mockito.internal.expectation.DefaultConstructorExpectationSetup.withArguments(DefaultConstructorExpectationSetup.java:48) [junit] at com.orbitz.galileo.host.robot.GalpoQueueConnectionTest.testNextPNRFromQueueHappyPath(GalpoQueueConnectionTest.java:62) [junit] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [junit] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) [junit] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) My class under test : GalpoQueueConnection is basically creating a new object of another class : QueueReadBuilder. I am trying to do something like: @RunWith(PowerMockRunner.class) @PrepareForTest({GalpoQueueConnection.class, ApolloProcUtils.class}) public class GalpoQueueConnectionTest extends TestCase{ @Test public void testNextPNRFromQueueHappyPath() throws Exception { QueueReadBuilder mockBuilder = mock(QueueReadBuilder.class); PowerMockito.whenNew(QueueReadBuilder.class).withArguments(anyString(), anyString(), anyString()).thenReturn(mockBuilder); } } It seems like somehow powermockito is trying to call IMockHandler, and I looked at Mockito 1.8.3 api, and there isn't any. Any suggestions/ clues would be welcome.

  • Why TabControl.SelectedContent != (TabControl.SelectedItem as TabItem).Content ?

    - by CannibalSmith
    The following sample shouldn't beep (in my opinion) but it does. Why? Does that mean the SelectedContent property is useless? Is it a bug in WPF? <TabControl SelectionChanged="TabControl_SelectionChanged"> <TabItem Header="Tab 1"> <Grid/> </TabItem> <TabItem Header="Tab 2"> <Grid/> </TabItem> </TabControl>   void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e) { var t = sender as TabControl; if (t.SelectedContent != (t.SelectedItem as TabItem).Content) Console.Beep(); }

  • using Windows Script Host

    - by Axarydax
    Hello, I am using windows script host for some kind of installer application and I'm creating shortcuts in start menu with it. This problem came up when I switched to x64 environment (win7 ultimate x64+vs2010) I added a reference to Windows Script Host Object Model (from c:\windows\syswow64\wshom.ocx), it generated Interop.IWshRuntimeLibrary dll. I added 'using IWshRuntimeLibrary;' to my .cs files, but when I tried to create WshShell sh = new WshShellClass(); it throws an exception: Could not load file or assembly 'Interop.IWshRuntimeLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format. I assume that I would need 64-bit version of that wshom.ocx for this to work, but I don't know what should I try. Or I'll just dump Windows Script stuff, but I need another way to create start menu shortcuts from .net application. Thanks

  • mongo mapper with STI with more than one type?

    - by holden
    I have a series of models all which inherit from a base model Properties For example Bars, Restaurants, Cafes, etc. class Property include MongoMapper::Document key :name, String key :_type, String end class Bar < Property What I'm wondering is what to do with the case when a record happens to be both a Bar & a Restaurant? Is there a way for a single object to inherit the attributes of both models? And how would it work with the key :_type?

  • Binding collection indexes to a WPF DataGrid at runtime

    - by bearda
    After trying to develop our own control to display a table of data we stumbled on the WPF toolkit DataGrid and thought we were saved. A couple hours later I'm scratching my head trying to figure out if it can do what we really want it to do. The DataGrid seems to be based on displaying various properties of a single object, where I think I need something that can display a collection's items, I want to display a table of strings with a variable number of rows and a variable number of columns. Each row represents the state of a number of inputs at a given time. The number of samples may change, and the number of inputs may change at runtime. As a result, I can't create a custom object that represents a row with a property for each input. This makes the DataGrid binding more complicated, since I can't bind to a fixed property for each column. I thought I found a workaround for this by binding to ".[" + channelIndex + ]" but it hasn't worked out quite the way I wanted. Right now I have a collection of a collection of strings that represents the two-dimensional array of strings. I'm using ObservableCollection so string change event notifications work, but I can use any collection type needed. It looked like everything was working great until I realized that every row was showing the same line of data. Binding in C# is not my strong suit, so I'm kind of lost on what's going wrong. Is what I'm trying to do overall even possible with the WPF Toolkit DataGrid? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using Microsoft.Windows.Controls; using System.ComponentModel; using System.Collections; using System.Collections.ObjectModel; namespace WRE.NGDAS.UILayer { /// <summary> /// Interaction logic for DataTableControl.xaml /// </summary> public partial class DataTableControl : UserControl { #region Constants private const int lineHeight = 25; #endregion #region Type Definitions private class TableChannelInfo { internal string ChannelName = string.Empty; internal int Column = 0; public override string ToString() { return ChannelName; } } internal class NotifyString : INotifyPropertyChanged { private string text = String.Empty; public event PropertyChangedEventHandler PropertyChanged; public string Text { get { return text; } set { text = value; NotifyPropertyChanged( "Text" ); } } public NotifyString(string newText) { text = newText; } protected void NotifyPropertyChanged( string propertyChanged ) { if ( PropertyChanged != null ) { PropertyChanged(this, new PropertyChangedEventArgs(propertyChanged)); } } } #endregion #region Private Data Members string[] channels = null; int numberFixed = 0; int numberOfRows = 0; ObservableCollection<ObservableCollection<NotifyString>> tableText = null; #endregion public DataTableControl( List<string> channelNames, List<string> nameToolTips, int numberFixedColumns, int numberRows ) { InitializeComponent(); numberFixed = numberFixedColumns; numberOfRows = numberRows; tableText = new ObservableCollection<ObservableCollection<NotifyString>>(); dataGrid.ItemsSource = tableText; channels = new string[channelNames.Count]; for (int channelIndex = 0; channelIndex < channelNames.Count; channelIndex++) { channels[channelIndex] = channelNames[channelIndex]; tableText.Add(new ObservableCollection<NotifyString>()); for (int i = 0; i < numberOfRows; i++) { tableText[channelIndex].Add( new NotifyString(String.Empty) ); } Binding textBinding = new Binding( ".[" + channelIndex + "]" ); textBinding.Mode = BindingMode.OneWay; textBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged; textBinding.Source = tableText[channelIndex]; DataGridTextColumn newColumn = new DataGridTextColumn(); newColumn.Header = channelNames[channelIndex]; newColumn.DisplayIndex = channelIndex; newColumn.Binding = textBinding; if ( channelIndex < numberFixed ) { newColumn.CanUserReorder = false; } dataGrid.Columns.Add(newColumn); } //Height = lineHeight + numberOfRows * lineHeight; } internal void UpdateChannelRow( int rowNumber, List<string> channelValues, DisplayColors color ) { if ( rowNumber < numberOfRows ) { for (int column = 0; column < channelValues.Count; column++) { if ( column < channels.GetLength(0) ) { tableText[column][rowNumber].Text = channelValues[column]; } } } } } }

  • Android 2.1 View's getDrawingCache() method always returns null

    - by Impression
    Hello, I'm working with Android 2.1 and have the following problem: Using the method View.getDrawingCache() always returns null. Example code: public void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final View view = findViewById(R.id.ImageView01); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); final Bitmap bmp = view.getDrawingCache(); System.out.println(bmp); } I've already tried different ways to configure the View object for generating the drawing cache (e.g. View.setWillNotDraw(boolean) and View.setWillNotCacheDrawing(boolean)), but nothing works. What is the right ways, or what do I wrong?

    Hi I want to create a JSON array. I have tried using: JSONArray jArray = new JSONArray(); while(itr.hasNext()){ int objId = itr.next(); jArray.put(objId, odao.getObjectName(objId)); } results = jArray.toString(); Note: odao.getObjectName(objId) retrieves a name based on the "object Id" which is called objId However I get a very funny looking array like [null,null,null,"SomeValue",null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,"AnotherValue",null,null,null,null,null,null,null,null,null,null,"SomethingElse","AnotherOne","LastOne"] With only "LastOne" being displayed when I retrieve it using jQuery. The Array SHould look like {["3":"SomeValue"],["40":"AnotherValue"],["23":"SomethingElse"],["9":"AnotherOne"],["1":"LastOne"]} The numbers aren't showing up at all for some reason in the array that I am getting

  • C# - Pass by value & Pass by Reference

    - by Lijo
    Hi Team, Could you please explain the following behavior of C# Class. I expect the classResult as "Class Lijo"; but actual value is “Changed”. We’re making a copy of the reference. Though the copy is pointing to the same address, the method receiving the argument cannot change original. Still why the value gets changed ? public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Person p = new Person(); p.Name = "Class Lijo"; Utilityclass.TestMethod(p); string classResult = p.Name; Response.Write(classResult); } } public class Utilityclass { public static void TestMethod(Person k) { k.Name = "Changed"; } } public class Person { private string name; public string Name { get { return name; } set { name = value; } } } Thanks Lijo

  • How to follow user location with MapKit

    - by Bloudermilk
    I'm using MapKit to display the user's location relative to pins around them. I'd like to be able to mimic the functionality that Maps provides via the crosshair button in the lower left-hand corner of the screen. I'm already aware that MapKit provides a CLLocation object with the user's location via MKUserLocation, I just wanted to seek advice on how I should keep focus on that location. My initial inclination was to use an NSTimer to center the map on that coordinate every 500ms or so. Is there a better way to do this? Is there something built in to MapKit that I'm missing that will accomplish this? Thanks so much, Brendan

  • Session variable in WCF application

    - by kaivalya
    I need to use or stimulate a very simple session object inside my WCF app. I simply need to store some values at the beginning of a call and I need access to these values while I go through some different methods of my service. Asp.NET session would be very ideal to use for this so I need to find out what is available on a WCF app for storing such values. Note: this is just a per call session, I don't need to retain this session between different calls from the client to service and such..

  • Implicit casting in VB.NET

    - by Shimmy
    The question is intended for lazy VB programmers. Please. In vb I can do and I won't get any errors. Example 1 Dim x As String = 5 Dim y As Integer = "5" Dim b As Boolean = "True" Example 2 Dim a As EnumType = 4 Dim v As Integer = EnumType.EnumValue Example 3 Private Sub ButtonClick(sender As Object, e As EventArgs) Dim btn As Button = sender End Sub Example 4 Private Sub ButtonClick(sender As Button, e As EventArgs) Dim data As Contact = sender.Tag End Sub If I surely know the expected runtime type, is this 'forbidden' to rely on the vb-language built-in casting? When can I rely? Thanks

  • Simple python oo issue

    - by Alex K
    Hello, Have a look a this simple example. I don't quite understand why o1 prints "Hello Alex" twice. I would think that because of the default self.a is always reset to the empty list. Could someone explain to me what's the rationale here? Thank you so much. class A(object): def __init__(self, a=[]): self.a = a o = A() o.a.append('Hello') o.a.append('Alex') print ' '.join(o.a) # >> prints Hello Alex o1 = A() o1.a.append('Hello') o1.a.append('Alex') print ' '.join(o1.a) # >> prints Hello Alex Hello Alex

  • Silverlight DataGrid set cell IsReadOnly programatically

    - by Brandon Montgomery
    I am binding a data grid to a collection of Task objects. A particular column needs some special rules pertaining to editing: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" /> What I want to do is set the IsReadOnly property only for each task's percent complete cell based on a property on the actual Task object. I've tried this: <!--Percent Complete--> <data:DataGridTextColumn Header="%" ElementStyle="{StaticResource RightAlignStyle}" Binding="{Binding PercentComplete, Mode=TwoWay, Converter={StaticResource PercentConverter}}" IsReadOnly={Binding IsNotLocalID} /> but apparently you can't bind to the IsReadOnly property on a data grid column. What is the best way do to do what I am trying to do?

  • How does one check if a table exists in an Android SQLite database?

    - by camperdave
    I have an android app that needs to check if there's already a record in the database, and if not, process some things and eventually insert it, and simply read the data from the database if the data does exist. I'm using a subclass of SQLiteOpenHelper to create and get a rewritable instance of SQLiteDatabase, which I thought automatically took care of creating the table if it didn't already exist (since the code to do that is in the onCreate(...) method). However, when the table does NOT yet exist, and the first method ran upon the SQLiteDatabase object I have is a call to query(...), my logcat shows an error of "I/Database(26434): sqlite returned: error code = 1, msg = no such table: appdata", and sure enough, the appdata table isn't being created. Any ideas on why? I'm looking for either a method to test if the table exists (because if it doesn't, the data's certainly not in it, and I don't need to read it until I write to it, which seems to create the table properly), or a way to make sure that it gets created, and is just empty, in time for that first call to query(...)

  • How to add icons to a PopUpMenuButton in Flex 3 using an XML file

    - by user168610
    Hi, I've been looking at the following example for populating a PupUpMenuButton http://blog.flexexamples.com/2008/02/21/creating-a-custom-label-function-on-a-flex-popupmenubutton-control/ and would like to add icons to each menu. Ideally, I would specify the icon in the xml and assign it in a similar way to using labelFunction for the text. I'm pretty new to Flex and would appreciate some guidance with this. The only information I've found via google is to create a menu as follows (seems I can't include more than one url, but it is an example that creates a menu object using the following function): private function initMenu():void { menu = new Menu(); menu.dataProvider = xmlList; menu.labelField = "@label"; menu.iconField = "@icon"; } but I would really prefer to build it all from the XML file. Many thanks, Bryn

  • System.Web.Security.FormsAuthentication.Encrypt returns null

    I'm trying to encrypt some userData to create my own custom IPrincipal and IIdentity objects using Forms authentication - I've serialized an object representing my logged in user to Json and created my FormsAuthentication ticket like so: string user_item = GetJsonOfLoggedinUser();/*get JSON representation of my logged in user*/ System.Web.Security.FormsAuthenticationTicket ticket = new System.Web.Security.FormsAuthenticationTicket(1, WAM.Utilities.SessionHelper.LoggedInEmployee.F_NAME + " " + WAM.Utilities.SessionHelper.LoggedInEmployee.L_NAME, DateTime.Now, DateTime.Now.AddMinutes(30), false, user_item); string encrypted_ticket = System.Web.Security.FormsAuthentication.Encrypt(ticket); HttpCookie auth_cookie = new HttpCookie( System.Web.Security.FormsAuthentication.FormsCookieName, encrypted_ticket); Response.Cookies.Add(auth_cookie); However, the string encrypted_ticket is always null. Is there a limit on the length of the user_item string? Thanks Mustafa

  • Argument exception after trying to use TryGetObjectByKey

    - by Rickjaah
    Hi, I'm trying to retrieve an object from my database using entity (framework 4) When I use the following code it gives an ArgumentException: An item with the same key has already been added. if (databaseContext.TryGetObjectByKey(entityKey, out result)) { return (result != null && result is TEntityObject) ? result as TEntityObject : null; } else { return null; } When I check the objectContext, I see the entities, but only if I enumerate the specific list of entities manually using VS2010, it works. What am I missing? Do I have to do something else before i can get the item from the database? I have lazy loading set to true. I searched google, but could not find any results, the same for the msdn library

  • Outlook 2003 View Control with C#

    I want to embed a custom c# windows form (or WPF) user control into an outlook view. I am using Outlook 2003 and Visual Studio 2008. I did download an example for Outlook 2007 here: http://blogs.msdn.com/e2eblog/archive/2008/01/09/outlook-folder-homepage-hosting-wpf-activex-and-windows-forms-controls.aspx and also here: http://msdn.microsoft.com/en-us/library/aa479345.aspx I tested it and under 2007 it is working, but for 2003 i am getting the following error when i want to open the view: Could not complete the operation due to error 80131509 I can start it from Visual Studio, it is registering the folder just fine, debugging works and all that. It creates an HTML page that contains my type as an object parameter - but the Initialize method that should be called is either not present (not shown via JS) or it has some errors. The breakpoints for RegisterSafeForScripting are also never hit - maybe related to that. Thx in advance!

  • Django: making raw SQL query, passing multiple/repeated params?

    Hopefully this should be a fairly straightforward question, I just don't know enough about Python and Django to answer it. I've got a raw SQL query in Django that takes six different parameters, the first two of which (centreLat and centreLng) are each repeated: query = "SELECT units, (SQRT(((lat-%s)*(lat-%s)) + ((lng-%s)*(lng-%s)))) AS distance FROM places WHERE lat<%s AND lat>%s AND lon<%s AND lon>%s ORDER BY distance;" params = [centreLat,centreLng,swLat,neLat,swLng,neLng] places = Place.objects.raw(query, params) How do I structure the params object and the query string so they know which parameters to repeat and where?
