    - by Pandiya Chendur
    My controller calls a repository class method on insert, [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create([Bind(Exclude = "Id")]FormCollection collection) { try { MaterialsObj materialsObj = new MaterialsObj(); materialsObj.Mat_Name = collection["Mat_Name"]; materialsObj.Mes_Id = Convert.ToInt64(collection["MeasurementType"]); materialsObj.Mes_Name = collection["Mat_Type"]; materialsObj.CreatedDate = System.DateTime.Now; materialsObj.CreatedBy = Convert.ToInt64(1); materialsObj.IsDeleted = Convert.ToInt64(1); consRepository.createMaterials(materialsObj); return RedirectToAction("Index"); } catch { return View(); } } and my repository class has this, public MaterialsObj createMaterials(MaterialsObj materialsObj) { db.Materials.InsertOnSubmit(materialsObj); return materialsObj; } But when i compile this i get The best overloaded method match for 'System.Data.Linq.Table<CrMVC.Models.Material>.InsertOnSubmit(CrMVC.Models.Material)' has some invalid arguments... cannot convert from 'CrMVC.BusinessObjects.MaterialsObj' to 'CrMVC.Models.Material'.. am i missing something?

  • Memory consumption of resource manager

    - by Quang Anh
    I'm writing a resource manager, which is required to be fast and has small memory foot-print. For example, I have an resource class class Abc { string m_name; string m_path; string handle; void SomeFunctions(); } And so on. Now I create and List and add 5000 items to it. How much memory will it consume? One more question: Can I find items base on handle number only, which is the int part of the Tuple?

  • How to add/register helpers with Zend Framework

    - by manyxcxi
    I'm just starting out with Zend Framework and am having issues using Zend_Controller_Action_HelperBroker::addPath() to add helpers. I'm not sure if my classes are named incorrectly, I'm giving it the wrong prefix, or what I'm doing wrong so I will post the code and file structure and get out of the way. In Bootstrap.php public function __construct($application) { ... // This works with a manual include_once('../application/plugins/helpers/Csrf.php'); //Zend_Controller_Action_HelperBroker::addHelper(new Application_Controller_Action_Helper_Csrf()); // This isn't picking up my helper class automagically Zend_Controller_Action_HelperBroker::addPath('../application/plugins/helpers','Application_Controller_Action_Helper'); ... } In application/plugins/helpers/Csrf.php class Application_Controller_Action_Helper_Csrf extends Zend_Controller_Action_Helper_Abstract { ... } My directory tree: / application/ ... plugins/ helpers/ Csrf.php CsrfProtect.php ...

  • Using XSD file in VS2005

    - by xt_20
    Hello all I want to write an XML file. I have created an XSD file named XMLSchema.xsd, and run the command 'xsd /c XMLSchema.xsd' which generated a c# class file. Now, how do I use this file to generate XML files? Part of my code: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="XMLSchema" targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" > <xs:element name="root"> <xs:complexType> <xs:sequence> <xs:element name="Audit"> <xs:complexType> ... which generates a c# class 'root'. How do I call 'root' from my C# web program? Thanks

  • log4j.xml not found

    - by Farid
    Hi , How can we specify were log4j has to look at when trying to find its xml configuration file ? It seems that by default, log4j looks into the root of a class folder, I can say that using the debug log4j functionality and running my application from the IDE. However, I don't have any class folder in my jar anymore. And the log4j.xml file is at the root of the jar. I have already tried to set the option -Dlog4j.configuration=log4j.xml but it doesn't work. Thanks !

  • How to get Firefox to not continue to show "Transferring data from..." in browser status bar after a

    - by Edward Tanguay
    The following silverlight demo loads and displays a text file from a server. However, in Firefox (but not Explorer or Chrome) after you click the button and the text displays, the status bar continues to show "Transferring data from test.development..." which erroneously gives the user the belief that something is still loading. I've noticed that if you click on another Firefox tab and then back on the original one, the message goes away, so it seems to be just a Firefox bug that doesn't clear the status bar automatically. Is there a way to clear the status bar automatically in Firefox? or a way to explicitly tell it that the async loading is finished so it can clear the status bar itself? XAML: <UserControl x:Class="TestLoad1111.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <StackPanel Margin="10"> <StackPanel HorizontalAlignment="Left" Orientation="Horizontal" Margin="0 0 0 10"> <Button Content="Load Text" Click="Button_LoadText_Click"/> </StackPanel> <TextBlock Text="{Binding Message}" /> </StackPanel> </UserControl> Code Behind: using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.ComponentModel; namespace TestLoad1111 { public partial class MainPage : UserControl, INotifyPropertyChanged { #region ViewModelProperty: Message private string _message; public string Message { get { return _message; } set { _message = value; OnPropertyChanged("Message"); } } #endregion public MainPage() { InitializeComponent(); DataContext = this; } private void Button_LoadText_Click(object sender, RoutedEventArgs e) { WebClient webClientTextLoader = new WebClient(); webClientTextLoader.DownloadStringAsync(new Uri("http://test.development:111/testdata/test.txt?" + Helpers.GetRandomizedSuffixToPreventCaching())); webClientTextLoader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClientTextLoader_DownloadStringCompleted); } void webClientTextLoader_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { Message = e.Result; } #region INotifiedProperty Block public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler(this, new PropertyChangedEventArgs(propertyName)); } } #endregion } public static class Helpers { private static Random random = new Random(); public static int GetRandomizedSuffixToPreventCaching() { return random.Next(10000, 99999); } } }

  • Restore previously serialized JFrame-object, how?

    - by elementz
    Hi all. I have managed to serialize my very basic GUI-object containing a JTextArea and a few buttons to a file 'test.ser'. Now, I would like to completely restore the previously saved state from 'test.ser', but seem to have a misconception of how to properly deserialize an objects state. The class MyFrame creates the JFrame and serializes it. public class MyFrame extends JFrame implements ActionListener { // Fields JTextArea textArea; String title; static MyFrame gui = new MyFrame(); private static final long serialVersionUID = 1125762532137824262L; /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub gui.run(); } // parameterless default contructor public MyFrame() { } // constructor with title public MyFrame(String title) { } // creates Frame and its Layout public void run() { JFrame frame = new JFrame(title); JPanel panel_01 = new JPanel(); JPanel panel_02 = new JPanel(); JTextArea textArea = new JTextArea(20, 22); textArea.setLineWrap(true); JScrollPane scrollPane = new JScrollPane(textArea); scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED); panel_01.add(scrollPane); // Buttons JButton saveButton = new JButton("Save"); saveButton.addActionListener(this); JButton loadButton = new JButton("Load"); loadButton.addActionListener(this); panel_02.add(loadButton); panel_02.add(saveButton); // Layout frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(BorderLayout.CENTER, panel_01); frame.getContentPane().add(BorderLayout.SOUTH, panel_02); frame.setSize(300, 400); frame.setVisible(true); } /* * */ public void serialize() { try { ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("test.ser")); oos.writeObject(gui); oos.close(); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } public void actionPerformed(ActionEvent ev) { System.out.println("Action received!"); gui.serialize(); } } Here I try to do the deserialization: public class Deserialize { static Deserialize ds; static MyFrame frame; public static void main(String[] args) { try { ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.ser")); frame = (MyFrame) ois.readObject(); ois.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } Maybe somebody could point me into the direction where my misconception is? Thx in advance!

  • Passing Reference types by value in C#

    - by Ajit
    I want to pass a reference type by value to a method in C#. Is there a way to do it. In C++, I could always rely on the copy constructor to come into play if I wanted to pass by Value. Is there any way in C# except: 1. Explicitly creating a new object 2. Implementing IClonable and then calling Clone method. Here's a small example: Let's take a class A in C++ which implements a copy constructor. A method func1(Class a), I can call it by saying func1(objA) (Automatically creates a copy) Does anything similar exist in C#. By the way, I'm using Visual Studio 2005.

  • Making Global Struct in C++ Program

    - by mosg
    Hello world! I am trying to make global structure, which will be seen from any part of the source code. I need it for my big Qt project, where some global variables needed. Here it is: 3 files (global.h, dialog.h & main.cpp). For compilation I use Visual Studio (Visual C++). global.h #ifndef GLOBAL_H_ #define GLOBAL_H_ typedef struct TNumber { int g_nNumber; } TNum; TNum Num; #endif dialog.h #ifndef DIALOG_H_ #define DIALOG_H_ #include <iostream> #include "global.h" using namespace std; class ClassB { public: ClassB() {}; void showNumber() { Num.g_nNumber = 82; cout << "[ClassB][Change Number]: " << Num.g_nNumber << endl; } }; #endif and main.cpp #include <iostream> #include "global.h" #include "dialog.h" using namespace std; class ClassA { public: ClassA() { cout << "Hello from class A!\n"; }; void showNumber() { cout << "[ClassA]: " << Num.g_nNumber << endl; } }; int main(int argc, char **argv) { ClassA ca; ClassB cb; ca.showNumber(); cb.showNumber(); ca.showNumber(); cout << "Exit.\n"; return 0; } When I`m trying to build this little application, compilation works fine, but the linker gives me back an error: 1>dialog.obj : error LNK2005: "struct TNumber Num" (?Num@@3UTNumber@@A) already defined in main.obj Is there exists any solution? Thanks.

  • C# to Java: What is a [DefaultProperty("value")]?

    - by Shiftbit
    I do not understand how the DefaultProperty Metadata tag work or what it signifies. I've read the MSDN and went through the sample but I find it confusing. DefaultPropertyAttribute Class I've read a few blogs and they seem to refer to the indexers. I'm not sure why you would want metadata for your properties? I am coming from a Java background, perhaps a Java analogy would help. [DefaultProperty("Value")] public abstract class FOO<T> : ANY, IBAR<T> { public FOO() { } public FOO(T value) { this.Value = value; } public virtual T Value { get; set; } } Follow up: Property Grid

    I have a two lists of class object : private List<IntVector> UserData = new List<IntVector>(); private List<IntVector> EditData = new List<IntVector>(); UserData is the Master List and EditData is another list which would be used to add, delete, or modify the list. One of the class memeber is CaseNo which would not change for an IntVector. I have made changes in the EditData and would like to merge the changes to the UserData. Any idea how to do it ?

  • using CSS to center FLOATED input elements wrapped in a DIV

    - by Tim
    There's no shortage of questions and answers about centering but I've not been able to get it to work given my specific circumstances, which involve floating. I want to center a container DIV that contains three floated input elements (split-button, text, checkbox), so that when my page is resized wider, they go from this: ||.....[ ][v] [ ] [ ] label .....|| to this ||......................[ ][v] [ ] [ ] label.......................|| They float fine, but when the page is made wider, they stay to the left: ||.....[ ][v] [ ] [ ] label .......................................|| If I remove the float so that the input elements are stacked rather than side-by-side: [ ][v] [ ] [ ] label then they DO center correctly when the page is resized. SO it is the float being applied to the elements of the DIV#hbox inside the container that is messing up the centering. Is what I want to do impossible because of the way float is designed to work? Here is my DOCTYPE, and the markup does validate at w3c: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> Here is my markup: <div id="term1-container"> <div class="hbox"> <div> <button id="operator1" class="operator-split-button">equals</button> <button id="operator1drop">show all operators</button> </div> <div><input type="text" id="term1"></input></div> <div><input type="checkbox" id="meta2"></input><label for="meta2" class="tinylabel">meta</label></div> </div> </div> And here's the (not-working) CSS: #term1-container {text-align: center} .hbox {margin: 0 auto;} .hbox div {float:left; } I have also tried applying display: inline-block to the floated button, text-input, and checkbox; and even though I think it applies only to text, I've also tried applying white-space: nowrap to the #term1-container DIV, based on posts I've seen here on SO. And just to be a little more complete, here's the jQuery that creates the split-button: $(".operator-split-button").button().click( function() { alert( "foo" ); }).next().button( { text: false, icons: { primary: "ui-icon-triangle-1-s" } }).click( function(){positionOperatorsMenu();} ) })

  • [WM6] Owner of a component. What exactly is this for?

    - by kornelijepetak
    I am developing an app for Windows Mobile 6 and there is a CameraCaptureDialog class that enables me to call a camera app from my own application. The class has an Owner property that most examples on the internet set to "this". cam.Owner = this; What exactly does this do? I've seen a similar scenario with Windows Forms components/controls by setting the Parent control. In that case I guess it's used only for layout algorithms, but other than that, is there any useful purpose? I don't see how setting an owner of the CameraCaptureDialog can (and actually does not) make any difference (at least not a visible one). Any insight would be appreciated.

  • Unit Testing Model Classes that derive from NSManagedObject

    - by Matt Baker
    So...I'm trying to get unit tests set up in my iPhone App but I'm having some issues. I'm trying to test my model classes but they inherit directly from NSManagedObject. I'm sure this is a problem but I don't know how to get around it. Everything is building and running as expected but I get this error when calling any method on the class I'm testing: Unknown.m:0:0 unrecognized selector sent to instance 0xc2b120 If I follow this structure (http://chanson.livejournal.com/115621.html) to create my object in my tests I end up with another error entirely but it still doesn't help me. Basically my question is this: how can I test a class that inherits from NSManagedObject?

  • Resizing Tab Bar Controller Views (iPhone dev)

    - by damiandawber
    Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

  • hibernate formula with column

    - by coolguy
    I have a table with a column that will be encrypted by a trigger after the record is inserted. When I read the column, I need to apply a decrypt function in the hibernate domain class. While saving the object, the value of the column will be saved as such. While reading the column, apply a database function on the read data. @Formula and @Column annotation cannot be applied to an attribute in the entity class. How do I achieve this functionality without using one attribute for saving and another one with @Formula for reading it?

  • C++ Singleton Constructor and Destructor

Way 1: class Singleton { public: ~Singleton() { } private: Singleton() { } }; Way 2: class Singleton { public: ~Singleton(); private: Singleton(); }; In the source .cc file: Singleton::Singleton() { } Singleton::~Singleton() { } Initially, I have the implementation in a source file, but I was asked to remove it. Does anyone know why?

  • Problem with debug watch in Visual Studio with yield return enumerator methods

  • Developing for mobile devices and desktop

    - by Augusto
    Hi, I'm starting a new project. It will run on devices running Windows CE, Windows Mobile 6 and will also have a desktop version. The software will connect to some equipments through the serial port, using it's own protocol. Basically it will: connect to the equipment send and receive info read and write binary files These tasks will be shared between desktop and mobile devices. I've been searching the information I need, but I still have some doubts: If I target Windows CE devices it will work with Windows Mobile 6 too? Creating a class library targeting Windows CE will give me any trouble on using it in the desktop version? (when I add a reference to that class library, my VS says that I could experience some unexpected results) Is it possible to install .NET CF 3.5 on devices running Windows CE 4.2? Thanks!

  • PHP form post, automatically mapping to an object (model binding)

    - by Pete Nelson
    I do a lot of ASP.NET MVC 2 development, but I'm tackling a small project at work and it needs to be done in PHP. Is there anything built-in to PHP to do model binding, mapping form post fields to a class? Some of my PHP code currently looks like this: class EntryForm { public $FirstName = ""; public $LastName = ""; } $EntryForm = new EntryForm(); if ($_POST && $_POST["Submit"] == "Submit") { $EntryForm->FirstName = trim($_POST["FirstName"]); $EntryForm->LastName = trim($_POST["LastName"]); } Is there anything built-in to a typical PHP install that would do such mapping like you'd find in ASP.NET MVC, or does it require an additional framework?

  • How to disable UI control based on domain object's state?

    - by Subb
    Here's my problem. I have a somewhat complex domain object, which, depending on its state, responds to certain actions. I think the state pattern is pretty much the solution for that. However, I need to display which actions are possible at any moment in the UI. Ex: The domain object is an audio player. Some songs can't be skipped (like ads), so I need to disable the "next" and "previous" buttons in the GUI so the user have some kind of feedback of which action he can execute. I've looked at Swing's Action class (note: this is not a Java project), but I think I would need to keep every Actions in my domain object class (audio player), so it can enable or disable them depending on its own state (thus, affecting the UI). Is it the way to do it?
