  • Memory Leak with Swing Drag and Drop

    - by tom
    I have a JFrame that accepts top-level drops of files. However after a drop has occurred, references to the frame are held indefinitely inside some Swing internal classes. I believe that disposing of the frame should release all of its resources, so what am I doing wrong? Example import java.awt.datatransfer.DataFlavor; import java.io.File; import java.util.List; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.TransferHandler; public class DnDLeakTester extends JFrame { public static void main(String[] args) { new DnDLeakTester(); //Prevent main from returning or the jvm will exit while (true) { try { Thread.sleep(10000); } catch (InterruptedException e) { } } } public DnDLeakTester() { super("I'm leaky"); add(new JLabel("Drop stuff here")); setTransferHandler(new TransferHandler() { @Override public boolean canImport(final TransferSupport support) { return (support.isDrop() && support .isDataFlavorSupported(DataFlavor.javaFileListFlavor)); } @Override public boolean importData(final TransferSupport support) { if (!canImport(support)) { return false; } try { final List<File> files = (List<File>) support.getTransferable().getTransferData(DataFlavor.javaFileListFlavor); for (final File f : files) { System.out.println(f.getName()); } } catch (Exception e) { e.printStackTrace(); } return true; } }); setDefaultCloseOperation(DISPOSE_ON_CLOSE); pack(); setVisible(true); } } To reproduce, run the code and drop some files on the frame. Close the frame so it's disposed of. To verify the leak I take a heap dump using JConsole and analyse it with the Eclipse Memory Analysis tool. It shows that sun.awt.AppContext is holding a reference to the frame through its hashmap. It looks like TransferSupport is at fault. What am I doing wrong? Should I be asking the DnD support code to clean itself up somehow? I'm running JDK 1.6 update 19.

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ? Object.class : o.getClass(); } private Object[] getRecord(int rowIndex) { return (Object[]) data.get(rowIndex); } } public void valueChanged(ListSelectionEvent e) { if (!e.getValueIsAdjusting()) { ListSelectionModel lsm = (ListSelectionModel) e.getSource(); int index = lsm.getMinSelectionIndex(); if(model.getRecord(index)[0] == Boolean.FALSE) model.setValueAt(Boolean.TRUE, index, 0); else if(model.getRecord(index)[0] == Boolean.TRUE) model.setValueAt(Boolean.FALSE, index, 0); } } } Please reply soon as it is bugging me a lot Thank you in advance :)

  • how to use a class method as a WIN32 application callback method (WINPROC)... Error static struct HI

    - by numerical25
    I am receiving errors and at the same time trying to make this work so please read what I got to say. Thanks.... I am creating a c++ application and majority of the application is encapsulated into a class. That means that my WinProc function is a static class method that I use as my call back method for my win32 application. The problem is that since I created that as a win32 application, every class member I use inside that method has to be static as well. Including my HINSTANCE class which I use inside of it. Now I receive this error error LNK2001: unresolved external symbol "public: static struct HINSTANCE__ I need to figure out how to make this all work and below is my class declaration. My static member static HINSTANCE m_hInst is causing the error I believe. #pragma once #include "stdafx.h" #include "resource.h" #define MAX_LOADSTRING 100 class RenderEngine { protected: int m_width; int m_height; ATOM RegisterEngineClass(); public: static HINSTANCE m_hInst; //<------ This is causing the error HWND m_hWnd; int m_nCmdShow; TCHAR m_szTitle[MAX_LOADSTRING]; // The title bar text TCHAR m_szWindowClass[MAX_LOADSTRING]; // the main window class name bool InitWindow(); bool InitDirectX(); bool InitInstance(); //static functions static LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam); static INT_PTR CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam); int Run(); }; Below is the implementation #include "stdafx.h" #include "RenderEngine.h" bool RenderEngine::InitWindow() { RenderEngine::m_hInst = NULL; // Initialize global strings LoadString(m_hInst, IDS_APP_TITLE, m_szTitle, MAX_LOADSTRING); LoadString(m_hInst, IDC_RENDERENGINE, m_szWindowClass, MAX_LOADSTRING); if(!RegisterEngineClass()) { return false; } if(!InitInstance()) { return false; } return true; } ATOM RenderEngine::RegisterEngineClass() { WNDCLASSEX wcex; wcex.cbSize = sizeof(WNDCLASSEX); wcex.style = CS_HREDRAW | CS_VREDRAW; wcex.lpfnWndProc = RenderEngine::WndProc; wcex.cbClsExtra = 0; wcex.cbWndExtra = 0; wcex.hInstance = m_hInst; wcex.hIcon = LoadIcon(m_hInst, MAKEINTRESOURCE(IDI_RENDERENGINE)); wcex.hCursor = LoadCursor(NULL, IDC_ARROW); wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wcex.lpszMenuName = MAKEINTRESOURCE(IDC_RENDERENGINE); wcex.lpszClassName = m_szWindowClass; wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL)); return RegisterClassEx(&wcex); } LRESULT CALLBACK RenderEngine::WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { int wmId, wmEvent; PAINTSTRUCT ps; HDC hdc; switch (message) { case WM_COMMAND: wmId = LOWORD(wParam); wmEvent = HIWORD(wParam); // Parse the menu selections: switch (wmId) { case IDM_ABOUT: DialogBox(m_hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About); break; case IDM_EXIT: DestroyWindow(hWnd); break; default: return DefWindowProc(hWnd, message, wParam, lParam); } break; case WM_PAINT: hdc = BeginPaint(hWnd, &ps); // TODO: Add any drawing code here...

  • QuestionOrAnswer model?

    - by Mark
    My site has Listings. Users can ask Questions about listings, and the author of the listing can respond with an Answer. However, the Answer might need clarification, so I've made them recursive (you can "answer" an answer). So how do I set up the database? The way I have it now looks like this (in Django-style models): class QuestionOrAnswer(Model): user = ForeignKey(User, related_name='questions') listing = ForeignKey(Listing, related_name='questions') parent = models.ForeignKey('self', null=True, blank=True, related_name='children') message = TextField() But what bugs me is that listing is now an attribute of the answers as well (it doesn't need to be). What happens if the database gets mangled and an answer belongs to a different listing than its parent question? That just doesn't make any sense. We can separate it with polymorphism: QuestionOrAnswer user message created updated Question(QuestionOrAnswer) shipment Answer(QuestionOrAnswer) parent = ForeignKey(QuestionOrAnswer) And that ought to work, but now ever question and answer is split into 2 tables. Is it worth this overhead for clearly defined models?

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

    - by Vicky
    I have a gridview with edit option at the start of the row. Also I maintain a seperate table called Permission where I maintain user permissions. I have three different types of permissions like Admin, Leads, Programmers. These all three will have access to the gridview. Except admin if anyone tries to edit the gridview on clicking the edit option, I need to give an alert like This row has important validation and make sure you make proper changes. When I edit, the action with happen on table called Application. The table has a column called Comments. Also the alert should happen only when they try to edit rows where the Comments column have these values in them.

  • passing data from a client form via jquery ajax dinamicly

    - by quantum62
    i wanna insert specification of members that enter in textboxs of form in the database .i do this operation with jquery ajax when i call webmetod with static value the operation do successfully.for example this code is ok. $.ajax({ type: "POST", url:"MethodInvokeWithJQuery.aspx/executeinsert", data: '{ "username": "user1", "name":"john","family":"michael","password":"123456","email": "[email protected]", "tel": "123456", "codemeli": "123" }', contentType: "application/json; charset=utf-8", dataType: "json", async: true, cache: false, success: function (msg) { $('#myDiv2').text(msg.d); }, error: function (x, e) { alert("The call to the server side failed. " + x.responseText); } } ); but when i wanna use of values that enter in textboxes dynamically error occur.whats problem?i try this two code <script type="text/javascript"> $(document).ready( function () { $("#Button1").click( function () { var username, family, name, email, tel, codemeli, password; username = $('#<%=TextBox1.ClientID%>').val(); name = $('#<%=TextBox2.ClientID%>').val(); family = $('#<%=TextBox3.ClientID%>').val(); password = $('#<%=TextBox4.ClientID%>').val(); email = $('#<%=TextBox5.ClientID%>').val(); tel = $('#<%=TextBox6.ClientID%>').val(); codemeli = $('#<%=TextBox7.ClientID%>').val(); $.ajax( { type: "POST", url: "WebApplication20.aspx/executeinsert", data: "{'username':'username','name':name, 'family':family,'password':password, 'email':email,'tel':tel, 'codemeli':codemeli}", contentType: "application/json;charset=utf-8", dataType: "json", async: true, cache: false, success: function(msg) { alert(msg); }, error: function (x, e) { alert("The call to the server side failed.

  • Custom Message Box: Windows' "Move Cursor to Default Button" Feature

    - by Andreas Rejbrand
    In Microsoft Windows, there is a (highly useful) feature that automatically moves the cursor to the default button of a modal dialog box (activated in Win+R, "control mouse"). Now I have created a custom dialog box in Delphi (basically a TForm), see below. But, quite naturally, the cursor does not automatically move to the default button ("Yes" in this case), even though the feature is turned on in "control mouse". How to implement this feature using Windows API? I guess it would be sufficient to obtain the settings as a boolean (true if feature activated, false if not), and then simply move the cursor programmatically using SetCursorPos if true. But how to obtain this setting?

  • Scaling Java applications - existing cluster-aware IoC frameworks?

    - by Zoltan
    Most people use some kind of an IoC framework - Guice, Spring, you name it. Many of us need to scale their applications too, so they complicate their lifes with Terracotta, Glassfish/JBoss/insertyourfavouritehere clusters. But is it really the way to go? Are you using any of the above? Here's some ideas we currently have implemented in a yet-to-be-opensourced framework, and I'd like to see what you think of it, or maybe "it's a complete ripoff of XY!". cluster-wide object replication - give it a name, and whenever you do something (in any node) on such an object, it will get replicated - with different guarantees do transparent soft-loadbalancing - simplest scenario: restful webservice method call proxied to an other node view-only node injection: inject a proxy to a "named" object, and get your calls automatically proxied to a node Would you use something like that? Is there a current, stable, enterprise-ready implementation out there?

  • What version of DataAnnotations is included with ASP.NET MVC 2 RTM

    - by Nick Thoresby
    I'm working on a project using Visual Studio 2008 and have moved from the the MVC 2 Preview to RTM version. We would like to use model validation such as: public class ViewModel { [Required(ErrorMessage="UserName is required.")] [StringLength(10, ErrorMessage="UserName cannot be greater than 10 chars.")] public string UserName { get; set; } } [HttpPost] public ActionResult Register(ViewModel model) { if (ModelState.IsValid){} // Always true } However the ModelState.IsValid always returns true. I have a suspicion that it might be something to do with the version of System.ComponentModel.DataAnnotations.dll that we are referencing, currently version 99.0.0.0, which seems rather odd. Does anyone know what version of this dll is included with the MVC 2 RTM for Visual Studio 2008?

  • In MATLAB can I convert a java boolean to a MATLAB logical?

    - by Adrian
    In MATLAB I'm using a couple of java routines I've written to interface with a MyQSL database. One routine returns a boolean value result <1x1 java.lang.Boolean> >> result result = true When I then use it in a conditional statement I get an error message. >> if result, disp('result is true') end ??? Conversion to logical from java.lang.Boolean is not possible. Is there a way to use the java boolean class as a MATLAB logical type? Or do I have to resort to returning integer values from my java routines?

  • LoaderContext and ApplicationDomain changes with Adobe AIR ?

    - by Tyn
    Hello, I'm currently experimenting with loading external SWF files from both an standard AS3 application, and an AIR application. It seems that the AIR application doesn't act the same way a standard SWF run by the Flash Player does. According to the documentation, the applicationDomain property of LoaderContext is usable in an AIR application too, but it just seems to be not working. I have the following code : package { import flash.display.Loader; import flash.display.LoaderInfo; import flash.display.Sprite; import flash.events.Event; import flash.net.URLRequest; import flash.system.ApplicationDomain; import flash.system.LoaderContext; public class Invoker extends Sprite { private var _ldr : Loader; public function Invoker() { _ldr = new Loader(); _ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onChildOneComplete); var ldrC : LoaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) ); _ldr.load(new URLRequest("otherSwf.swf"), ldrC); } private function onChildOneComplete(e : Event) : void { var c1ad : ApplicationDomain = (e.target as LoaderInfo).applicationDomain; var inad : ApplicationDomain = ApplicationDomain.currentDomain; trace("Child One parentDomain : " + c1ad.parentDomain); trace("Invoker parentDomain : " + inad.parentDomain); trace("Child One has Invoker : " + c1ad.hasDefinition("Invoker")); trace("Invoker has Invoker : " + inad.hasDefinition("Invoker")); } } } Compiling this code as an SWF file and launching it with the Flash Player does this output, which seems right : Child One parentDomain : [object ApplicationDomain] Invoker parentDomain : null Child One has Invoker : true Invoker has Invoker : true But the same code as an AIR application does a different output : Child One parentDomain : null Invoker parentDomain : null Child One has Invoker : false Invoker has Invoker : true According to the documentation, the first output (using a SWF with Flash Player, and not an AIR application) is the right one. Also, playing around with this snippet and changing the application domain to others possible configurations (like new ApplicationDomain(null), or ApplicationDomain.currentDomain) does exaclty what the documentation says with the SWF, but does not change the output of the AIR application. Any clue why AIR is simply ignoring the application domain passed to the loader context ? Any documentation about this particular issue ? Thank you very much.

    I need to do something like this, My two tables have the same signature, but different class so It suppose to work but it is not working. var myTable; if (booleanVariable == true) { myTable = table1; } else { myTable = table2; } var myLinq1 = from p in myTable join r in myOtherTable select p; In this case, I have to initialize myTable I have tried also, var myTablev= table2; if (booleanVariable == true) { myTable = table1; } var myLinq1 = from p in myTable join r in myOtherTable select p; then var is type table2, then it can't be changed to table1 type. I need help, I don't want to make a copy paste of all the code. the linq query is huge, and it s nested with 5 or 6 queries. also I have to do this on 12 different methods. Thanks a lot for your help.

  • How to override form just on one page?

    - by user363036
    OK so this is my hook form alter function.It is causing all the registration forms on site to be over written which I do not want as I just want it on this page. function special_registration_form_alter(&$form, $form_state, $form_id) { if ($form_id == 'user_register') { drupal_set_title(t('Custom registration')); $form['firstname'] = array('#type' = 'textfield', '#title' = t('First Name: *'), '#required' = TRUE, '#size' = 45, '#weight' = - 100,); $form['lastname'] = array('#type' = 'textfield', '#title' = t('Last Name: *'), '#required' = TRUE, '#size' = 45, '#weight' = - 99,); } I only first name and last name to be captured and stored in a different table just on this page. On other pages I just want the good old fashioned form. Do I still need to change the weight? I know I am missing something elementary.

  • VB.net: Custom ' TODO: List on an Interface

    - by Shiftbit
    How do I add my own todo and comments list to appear on Interfaces? I want it to pop up like IDisposable does: Public Class Foo : Implements IDisposable Private disposedValue As Boolean = False ' To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub #Region " IDisposable Support " ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub #End Region End Class Whenever I enter my own comments and todo list they are never autogenerated like IDisposable Interface does. I would like my own Interfaces to preserve the comments so that I can share my Interfaces with in source documentation.

  • Mongodb using db.help() on a particular db command

    - by user1325696
    When I type db.help() It returns DB methods: db.addUser(username, password[, readOnly=false]) db.auth(username, password) ... ... db.printShardingStatus() ... ... db.fsyncLock() flush data to disk and lock server for backups db.fsyncUnock() unlocks server following a db.fsyncLock() I'd like to find out how to get more detailed help for the particular command. The problem was with the printShardingStatus as it returned "too many chunks to print, use verbose if you want to print" mongos> db.printShardingStatus() --- Sharding Status --- sharding version: { "_id" : 1, "version" : 3 } shards: { "_id" : "shard0000", "host" : "localhost:10001" } { "_id" : "shard0001", "host" : "localhost:10002" } databases: { "_id" : "admin", "partitioned" : false, "primary" : "config" } { "_id" : "dbTest", "partitioned" : true, "primary" : "shard0000" } dbTest.things chunks: shard0001 12 shard0000 19 too many chunks to print, use verbose if you want to for ce print I found that for that particular command I can specify boolean parameter db.printShardingStatus(true) which wasn't shown using db.help().
