  • Oracle s'associe à Nokia pour utiliser ses cartes dans ses applications d'entreprise, bonne nouvelle pour le Finlandais

    Oracle s'associe à Nokia pour utiliser ses cartes Dans ses applications d'entreprise, bonne nouvelle pour le Finlandais A mesure que la mobilité monte en puissance, les services de cartographie deviennent de plus en plus stratégique. En témoigne le récent abandon des Googles Maps par Apple dans iOS. Apple qui ne pouvait pas longtemps dépendre d'un concurrent dans ce domaine. Mais ce mouvement ne concerne pas que le grand public. Loin de là. Les CRM par exemple, sont de plus en plus portés sur tablette et les outils de BI prennent de plus en plus en compte des problématiques géospatiales (implantation de maga...

  • iTextSharp Creating a Footer Page # of #

    - by Rob
    Hi, I'm trying to create a footer on each of the pages in a PDF document using iTextSharp in the format Page # of # following the tutorial on the iText pages and the book. Though I keep getting an exception on cb.SetFontAndSize(helv, 12); - object reference not set to an object. Can anyone see the issue? Code is below. Thanks, Rob public class MyPdfPageEventHelpPageNo : iTextSharp.text.pdf.PdfPageEventHelper { protected PdfTemplate total; protected BaseFont helv; private bool settingFont = false; public override void OnOpenDocument(PdfWriter writer, Document document) { total = writer.DirectContent.CreateTemplate(100, 100); total.BoundingBox = new Rectangle(-20, -20, 100, 100); helv = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.WINANSI, BaseFont.NOT_EMBEDDED); } public override void OnEndPage(PdfWriter writer, Document document) { PdfContentByte cb = writer.DirectContent; cb.SaveState(); string text = "Page " + writer.PageNumber + " of "; float textBase = document.Bottom - 20; float textSize = 12; //helv.GetWidthPoint(text, 12); cb.BeginText(); cb.SetFontAndSize(helv, 12); if ((writer.PageNumber % 2) == 1) { cb.SetTextMatrix(document.Left, textBase); cb.ShowText(text); cb.EndText(); cb.AddTemplate(total, document.Left + textSize, textBase); } else { float adjust = helv.GetWidthPoint("0", 12); cb.SetTextMatrix(document.Right - textSize - adjust, textBase); cb.ShowText(text); cb.EndText(); cb.AddTemplate(total, document.Right - adjust, textBase); } cb.RestoreState(); } public override void OnCloseDocument(PdfWriter writer, Document document) { total.BeginText(); total.SetFontAndSize(helv, 12); total.SetTextMatrix(0, 0); int pageNumber = writer.PageNumber - 1; total.ShowText(Convert.ToString(pageNumber)); total.EndText(); } }

  • Passing a parameter using RelayCommand defined in the ViewModel (from Josh Smith example)

    - by eesh
    I would like to pass a parameter defined in the XAML (View) of my application to the ViewModel class by using the RelayCommand. I followed Josh Smith's excellent article on MVVM and have implemented the following. XAML Code <Button Command="{Binding Path=ACommandWithAParameter}" CommandParameter="Orange" HorizontalAlignment="Left" Style="{DynamicResource SimpleButton}" VerticalAlignment="Top" Content="Button"/> ViewModel Code public RelayCommand _aCommandWithAParameter; /// <summary> /// Returns a command with a parameter /// </summary> public RelayCommand ACommandWithAParameter { get { if (_aCommandWithAParameter == null) { _aCommandWithAParameter = new RelayCommand( param => this.CommandWithAParameter("Apple") ); } return _aCommandWithAParameter; } } public void CommandWithAParameter(String aParameter) { String theParameter = aParameter; } #endregion I set a breakpoint in the CommandWithAParameter method and observed that aParameter was set to "Apple", and not "Orange". This seems obvious as the method CommandWithAParameter is being called with the literal String "Apple". However, looking up the execution stack, I can see that "Orange", the CommandParameter I set in the XAML is the parameter value for RelayCommand implemenation of the ICommand Execute interface method. That is the value of parameter in the method below of the execution stack is "Orange", public void Execute(object parameter) { _execute(parameter); } What I am trying to figure out is how to create the RelayCommand ACommandWithAParameter property such that it can call the CommandWithAParameter method with the CommandParameter "Orange" defined in the XAML. Is there a way to do this? Why do I want to do this? Part of "On The Fly Localization" In my particular implementation I want to create a SetLanguage RelayCommand that can be bound to multiple buttons. I would like to pass the two character language identifier ("en", "es", "ja", etc) as the CommandParameter and have that be defined for each "set language" button defined in the XAML. I want to avoid having to create a SetLanguageToXXX command for each language supporting and hard coding the two character language identifier into each RelayCommand in the ViewModel.

  • WPF MVVM ComboBox SelectedItem or SelectedValue not working

    - by cjibo
    Update After a bit of investigating. What seems to be the issue is that the SelectedValue/SelectedItem is occurring before the Item source is finished loading. If I sit in a break point and weight a few seconds it works as expected. Don't know how I'm going to get around this one. End Update I have an application using in WPF using MVVM with a ComboBox. Below is the ViewModel Example. The issue I'm having is when we leave our page and migrate back the ComboBox is not selecting the current Value that is selected. View Model public class MyViewModel { private MyObject _selectedObject; private Collection<Object2> _objects; private IModel _model; public MyViewModel(IModel model) { _model = model; _objects = _model.GetObjects(); } public Collection<MyObject> Objects { get { return _objects; } private set { _objects = value; } } public MyObject SelectedObject { get { return _selectedObject; } set { _selectedObject = value; } } } For the sake of this example lets say MyObject has two properties (Text and Id). My XAML for the ComboBox looks like this. XAML <ComboBox Name="MyComboBox" Height="23" Width="auto" SelectedItem="{Binding Path=SelectedObject,Mode=TwoWay}" ItemsSource="{Binding Objects}" DisplayMemberPath="Text" SelectedValuePath="Id"> No matter which way I configure this when I come back to the page and the object is reassembled the ComboBox will not select the value. The object is returning the correct object via the get in the property though. I'm not sure if this is just an issue with the way the ComboBox and MVVM pattern works. The text box binding we are doing works correctly.

  • Use MTOM/streaming from C# calling a webservice in java exposed via jaxws

    - by raticulin
    We have this webservice created with jax-ws @WebService(name = "Mywebser", targetNamespace = "http://namespace") @MTOM(threshold = 2048) @SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED) public class Mywebser { @WebMethod(operationName = "doStreaming", action = "urn:doStreaming") @WebResult(name = "return") public ResultInfo doStreaming(String username, String pwd, @XmlMimeType("application/octet-stream") DataHandler data, boolean overw){ ... } } The generated client side looks like this: @WebMethod(action = "urn:doStreaming") @WebResult(targetNamespace = "") @RequestWrapper(localName = "doStreaming", targetNamespace = "http://namespace", className = "com.mypack.client.doStreaming") @ResponseWrapper(localName = "doStreamingResponse", targetNamespace = "http://namespace", className = "com.mypack.client.doStreamingResponse") public ResultInfo doStreaming( @WebParam(name = "arg0", targetNamespace = "") String arg0, @WebParam(name = "arg1", targetNamespace = "") String arg1, @WebParam(name = "arg2", targetNamespace = "") DataHandler arg2, @WebParam(name = "arg3", targetNamespace = "") boolean arg3); By using it this way it uses streaming properly (verified we can pass an argument of 80mb when the jvm had less allowed. MywebserService serv = ...; Mywebser wso = serv.getMywebserPort(new MTOMFeature()); Map<String, Object> ctxt = ((BindingProvider) wso).getRequestContext(); ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 8192); DataHandler dataHandler = new DataHandler(new FileDataSource("c:\\temp\\A.dat")); arcres = wso.doStreaming("a", "b", dataHandler, true); We generate a clienet for .net, with VS2008, using "Add Web Reference", we get this C# code: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("urn:doStreaming",RequestNamespace="http://namespace",ResponseNamespace="http://namespace",Use=System.Web.Services.Description.SoapBindingUse.Literal,ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("return",Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public ResultInfo doStreaming( [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg0, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string arg1, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified,DataType="base64Binary")] byte[] arg2, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] bool arg3) Apparently this is not using streaming? The type base64Binary of arg2 seems not the right one? In java it's a DataHandler. By testing it with low memory on the java side we can see it is not using streaming as it fails with OOM. Does someone knows if this is possible, and if so how? Our environment: server: jdk1.6, jaxws 2.1.7 client: C# 2.0, visual studio 2008

  • Silverlight data binding to parent user control's properties with using MVVM in both controls

    - by MagicMax
    Hello! I have two UserControls ("UserControlParentView" and "UserControlChildView") with MVVM pattern implemented in both controls. Parent control is a container for Child control and child control's property should be updated by data binding from Parent control in order to show/hide some check box inside Child control. Parent Control Description UserControlParentViewModel has property: private bool isShowCheckbox = false; public bool IsShowCheckbox { get { return isShowCheckbox; } set { isShowCheckbox = value; NotifyPropertyChanged("IsShowCheckbox"); } } UserControlParentViewModel - how I set DataContext of Parent control: public UserControlParentView() { InitializeComponent(); this.DataContext = new UserControlParentViewModel(); } UserControlParentView contains toggle button (in XAML), bound to UserControlParentViewModel's property IsShowCheckbox <ToggleButton Grid.Column="1" IsChecked="{Binding IsShowCheckbox, Mode=TwoWay}"></ToggleButton> Also Parent control contains instance of child element (somewhere in XAML) <local:UserControlChildView IsCheckBoxVisible="{Binding IsShowCheckbox}" ></local:UserControlChildView> so property in child control should be updated when user togggle/untoggle button. Child control contains Boolean property to be updated from parent control, but nothing happened! Breakpoint never fired! Property in UserControlChildView that should be updated from Parent control (here I plan to make chechBox visible/hidden in code behind): public bool IsCheckBoxVisible { get { return (bool)GetValue(IsCheckBoxVisibleProperty); } set { SetValue(IsCheckBoxVisibleProperty, value); } } // Using a DependencyProperty as the backing store for IsCheckBoxVisible. This enables animation, styling, binding, etc... public static readonly DependencyProperty IsCheckBoxVisibleProperty = DependencyProperty.Register("IsCheckBoxVisible", typeof(bool), typeof(TopMenuButton), new PropertyMetadata(false)); So the question is - what I'm doing wrong? Why child's property is never updated? BTW - there is no any binding error warnings in Output window...

  • Unable to determine the provider name for connection of type 'System.Data.SqlServerCe.SqlCeConnectio

    - by Hobbes1312
    Hi, i am using the Ado.Net Entity Framework with Code Only (Tutorial at: ADO.NET team blog) and i want to be as much database independent as possible. In my first approach i just want to go for Sql Express and Sql Compact databases. With Sql Express everthing works fine but with Sql Compact i get the exception mentioned in my question. Does anybody knows if it is possible to connect to Sql Compact with the Code Only approach? (with a generated .edmx file for a Sql Compact database everthing works fine, but i want to use code only!) Here is some code: My Class which is building the DataContext: public class DataContextBuilder : IDataContextBuilder { private readonly DbProviderFactory _factory; public DataContextBuilder(DbProviderFactory factory) { _factory = factory; } #region Implementation of IDataContextBuilder public IDataContext CreateDataContext(string connectionString) { var builder = new ContextBuilder<DataContext>(); RegisterConfiguration(builder); var connection = _factory.CreateConnection(); connection.ConnectionString = connectionString; var ctx = builder.Create(connection); return ctx; } #endregion private void RegisterConfiguration(ContextBuilder<DataContext> builder) { builder.Configurations.Add(new PersonConfiguration()); } } The line var ctx = builder.Create(connection); is throwing the exception. The IDataContext is just a simple Interface for the ObjectContext: public interface IDataContext { int SaveChanges(); IObjectSet<Person> PersonSet { get; } } My connection string is configured in the app.config: <connectionStrings> <add name="CompactConnection" connectionString="|DataDirectory|\Test.sdf" providerName="System.Data.SqlServerCe.3.5" /> </connectionStrings> And the build action is started with var cn = ConfigurationManager.ConnectionStrings["CompactConnection"]; var factory = DbProviderFactories.GetFactory(cn.ProviderName); var builder = new DataContextBuilder(factory); var context = builder.CreateDataContext(cn.ConnectionString);

  • ObservableCollection is not updating Multibinding in C# WPF

    - by Decept
    I have a TreeView that creates all its items from databound ObservableCollections. I have a hierarchy of GameNode objects, each object has two ObservableCollections. One collections has EntityAttrib objects and the other have GameNode objects. You could say that the GameNode object represents folders and EntityAttrib represents files. To display both attrib and GameNodes in the same TreeView I use Multibinding. This all works fine in startup, but when I add a new GameNode somewhere in the hierarchy the TreeView is not updated. I set a breakpoint in my converter method but it's not called when adding a new GameNode. It seems that the ObservableCollection is not notifying the MultiBinding of the change. If I comment out the MultiBinding and only bind the GameNode collection it works as expected. XAML: <HierarchicalDataTemplate DataType="{x:Type local:GameNode}"> <HierarchicalDataTemplate.ItemsSource> <MultiBinding Converter="{StaticResource combineConverter}"> <Binding Path="Attributes" /> <Binding Path="ChildNodes" /> </MultiBinding> </HierarchicalDataTemplate.ItemsSource> <TextBlock Text="{Binding Path=Name}" ContextMenu="{StaticResource EntityCtxMenu}"/> </HierarchicalDataTemplate> C#: public class GameNode { string mName; public string Name { get { return mName; } set { mName = value; } } GameNodeList mChildNodes = new GameNodeList(); public GameNodeList ChildNodes { get { return mChildNodes; } set { mChildNodes = value; } } ObservableCollection<EntityAttrib> mAttributes = new ObservableCollection<EntityAttrib>(); public ObservableCollection<EntityAttrib> Attributes { get { return mAttributes; } set { mAttributes = value; } } } GameNodeList is a subclassed ObservableCollection

  • Mimicking the UltraGridColumnChooser's drag & drop ability

    - by Sören Kuklau
    (Infragistics 2008 Vol. 3, CLR 2.0) Infragistics's UltraGrid comes with a column chooser user control, which is simply a vertical arrangement of columns with checkboxes that toggle a column's hidden state. In addition, it allows you to pick a column and drag it directly to the grid so you don't have to manually position it afterwards. (This is particularly handy when you already have a lot of visible columns and have no clue where the new one ended up.) I'm building my own column chooser based on an UltraTree. Getting the checkboxes to behave the same wasn't an issue, but I haven't found a way to drag a column from the tree to the grid and have it accept it. In my tree, each UltraTreeNode has a Tag with the following struct: Private Structure DraggableGridColumn Public NodeKey As String Public NodeName As String Public ParentKey As String Public Column As UltraGridColumn End Structure I then have an event as follows: Private Sub columnsTree_SelectionDragStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles columnsTree.SelectionDragStart If columnsTree.SelectedNodes.Count <> 1 Then Return End If If Not TypeOf columnsTree.SelectedNodes(0).Tag Is DraggableGridColumn Then Return End If Dim column As UltraGridColumn = CType(columnsTree.SelectedNodes(0).Tag, DraggableGridColumn).Column columnsTree.DoDragDrop(column, DragDropEffects.All) End Sub In the DoDragDrop call, neither column (of type UltraGridColumn) nor column.Header (of type ColumnHeader) get accepted by the grid. I assume I'm sending the wrong type, and/or that the grid expects a special struct with some additional information. Unfortunately, I've also failed to catch an event (both on the column chooser side as well as on the grid side) where Infragistics's normal column chooser does this properly; the normal drag & drop events never seem to fire.

  • WPF derived ComboBox SelectedValuePath issue

    - by opedog
    In our application we have a very large set of data that acts as our data dictionary for ComboBox lists, etc. This data is staticly cached and keyed off of 2 variables, so I thought it wise to write a control that derived from ComboBox and exposed the 2 keys as DPs. When those 2 keys have proper values I set the ItemsSource of the ComboBox automatically from the data dictionary list it corresponds to. I also automatically set the SelectedValuePath and DisplayMemberPath to Code and Description, respectively. Here's how an example of how an item in the ItemsSource from the data dictionary list always looks: public class DataDictionaryItem { public string Code { get; set; } public string Description { get; set; } public string Code3 { get { return this.Get.Substring(0, 3); } } } The value of Code is always 4 bytes long, but sometimes I only need to bind 3 bytes of it. Hence, the Code3 property. Here's how the code looks inside my custom combobox to set the ItemsSource: private static void SetItemsSource(CustomComboBox combo) { if (string.IsNullOrEmpty(combo.Key1) || string.IsNullOrEmpty(combo.Key2)) { combo.ItemsSource = null; return; } List<DataDictionaryItem> list = GetDataDictionaryList(combo.Key1, combo.Key2); combo.ItemsSource = list; } Now, my problem is, when I change the SelectedValuePath in the XAML to Code3, it doesn't work. What I bind to SelectedValue still gets the full 4 character Code from DataDictionaryItem. I even tried rerunning SetItemsSource when the SelectedValuePath was changed and no dice. Can anyone see what I need to do to get my custom combobox to wake up and use the SelectedValuePath provided if it's overridden in the XAML? Tweaking the value in the property setter in my SelectedValue bound business object is not an option.

  • How to use custom IComparer for SortedDictionary?

    - by Magnus Johansson
    I am having difficulties to use my custom IComparer for my SortedDictionary<. The goal is to put email addresses in a specific format ([email protected]) as the key, and sort by last name. When I do something like this: public class Program { public static void Main(string[] args) { SortedDictionary<string, string> list = new SortedDictionary<string, string>(new SortEmailComparer()); list.Add("[email protected]", "value1"); list.Add("[email protected]", "value2"); foreach (KeyValuePair<string, string> kvp in list) { Console.WriteLine(kvp.Key); } Console.ReadLine(); } } public class SortEmailComparer : IComparer<string> { public int Compare(string x, string y) { Regex regex = new Regex("\\b\\w*@\\b", RegexOptions.IgnoreCase | RegexOptions.CultureInvariant | RegexOptions.IgnorePatternWhitespace | RegexOptions.Compiled ); string xLastname = regex.Match(x).ToString().Trim('@'); string yLastname = regex.Match(y).ToString().Trim('@'); return xLastname.CompareTo(yLastname); } } I get this ArgumentException: An entry with the same key already exists. when adding the second item. I haven't worked with a custom IComparer for a SortedDictionary before, and I fail to see my error , what am I doing wrong?

  • XmlSerializer Deserialize failures

    - by smvlad
    I have wsdl from third party server. Method that i'm interested in returns XmlNode. My thought was wrap web methods and use XmlSerializer to return strongly typed objects. Returned xml looks like this (i removed soap headers): <Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ResponseExt" xmlns="http://www.thirdparty.com/lr/"> <Code>0</Code> <Message>SUCCESS</Message> <SessionId>session_token</SessionId> </Response> Looked simple. Created a class: [XmlRoot("Response")] public class MyClass { public string Code {get; set;} public string Message {get; set;} public string SessionId {get; set;} } Processing time: //XmlNode node = xml from above XmlSerializer serializer = new XmlSerializer(typeof(MyClass)); XmlNodeReader reader = new XmlNodeReader(node); Myclass myclass = serializer.Deserialize(reader) as MyClass Last line is where it blows up with inner exception message: The specified type was not recognized: name='ResponseExt', namespace='http://www.thirdparty.com/lr/', at . I can't figure out how to make Serializer happy and what exactly these two mean xsi:type="ResponseExt" xmlns="http://www.thirdparty.com/lr/ As always any advice and pointer are appreciated

  • Autocompletebox text in Silverlight

    - by Ciaran
    I'm having trouble getting the autocomplete box in System.Windows.Controls.Input working as I wish. When I start typing the dropdown section that displays the filtered list doesn't show the property that I'm binding to, it shows the class name instead. So in the example below, when I type in my - instead of showing 'My Name' it shows MyNamespace.Person. However, when I select the item from the autocomplete list, it displays the FullName property in the textbox. I'm sure I'm just missing a simple autocomplete box property somewhere but I can't see it. Example code: public class Person { public string FirstName { get; set; } public string LastName { get; set; } public string FullName { get { return string.Format("{0} {1}", FirstName, LastName); } } } In my xaml code behind I create some Person objects and store them in a list and bind that list to an autocomplete box List<Person> people = new List<Person>(); people.Add(new Person { FirstName = "My", LastName = "Name" }); people.Add(new Person { FirstName = "Fernando", LastName = "Torres" }); acbNames.ItemsSource = people; My xaml: <my:AutoCompleteBox Name="acbNames" ValueMemberPath="FullName" /> /* after entering 'my', auto complete displays 'MyNamespace.Person' instead of 'My Name', but displays 'My Name' after selecting the item from the list */

  • WPF ICommand over a button

    - by toni
    Hi, I have implemented a custom IComand class for one of my buttons. The button is placed in a page 'MyPage.xaml' but its custom ICommand class is placed in another class, not in the MyPage code behind. Then from XAML I want to bind the button with its custom command class and then I do: MyPage.xaml: <Page ...> <Page.CommandBindings> <CommandBinding Command="RemoveAllCommand" CanExecute="CanExecute" Executed="Execute" /> </Page.CommandBindings> <Page.InputBindings> <MouseBinding Command="RemoveAllCommand" MouseAction="LeftClick" /> </Page.InputBindings> <...> <Button x:Name="MyButton" Command="RemoveAllCommand" .../> <...> </Page> and the custom command button class: // Here I derive from MyPage class because I want to access some objects from // Execute method public class RemoveAllCommand : MyPage, ICommand { public void Execute(Object parameter) { <...> } public bool CanExecute(Object parameter) { <...> } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } } My problem is how to say MyPage.xaml that Execute and CanExecute methods for the button is in another class and not the code behind where is placed the button. How to say these methods are in RemoveAllCommand Class in XAML page. Also I want to fire this command when click mouse event is produced in the button so I do an input binding, is it correct? Thanks

  • How to change theme for AlertDialog.

    - by Min Soo Kim
    Hello everyone, I was wondering if someone could help me out. I am trying to create a custom AlertDialog. In order to do this, I added the following line of code in styles.xml @drawable/color_panel_background color_panel_background.9.png is located in drawable folder. This is also available in Android SDK res folder. The following is the main activity. package com.customdialog; import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.DialogInterface; import android.os.Bundle; public class CustomDialog extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.setTheme(R.style.CustomAlertDialog); AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("HELLO!"); builder .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //MyActivity.this.finish(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //dialog.cancel(); } }); AlertDialog alertdialog = builder.create(); alertdialog.show(); } } In order to apply the theme to an AlertDialog, I had to set the theme to the current context. However, I just can't seem to get the app to show customized AlertDialog. Can anyone help me out with this, and thank you very much in advance!

    First of all, I've checked out all the SO threads, and googled my brains out. I must be missing something obvious. I'd really appreciate some help! This is what I've got. UploadController.cs using System.Web; using System.Web.Mvc; namespace NIMDocs.Controllers { public class UploadController : Controller { public ActionResult Index() { return View(); } public string Procssed(HttpPostedFileBase FileData) { // DO STUFF return "DUHR I AM SMART"; } } } Index for Upload <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>ITS A TITLE </title> <script src="../../Content/jqueryPlugins/uploadify/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="../../Content/jqueryPlugins/uploadify/swfobject.js" type="text/javascript"></script> <script src="../../Content/jqueryPlugins/uploadify/jquery.uploadify.v2.1.0.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#uploadify').fileUpload({ 'uploader': '../../Content/jqueryPlugins/uploadify/uploadify.swf', 'script': '/Upload/Processed', 'folder': '/uploads', 'multi': 'true', 'buttonText': 'Browse', 'displayData': 'speed', 'simUploadLimit': 2, 'cancelImg': '/Content/Images/cancel.png' }); }); </script> </head> <body> <input type="file" name="uploadify" id="uploadify" /> <p><a href="javascript:jQuery('#uploadify').uploadifyClearQueue()">Cancel All Uploads</a></p> </body> </html> What am I missing here? I've tried just about every path permutation for uploadify's "uploader" option. Absolute path, '/' prefixed, etc.

  • Error converting JSON to .Net object in asp.net

    - by Vinni
    Hello Guys, I am unable to convert JSON string to .net object in asp.net. I am sending JSON string from client to server using hidden field (by keeping the JSON object.Tostring() in hidden field and reading the hidden field value in code behind file) Json string/ Object: [[{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"11","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"11","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"2","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"2","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"67","HostingTypeID":"3"}, {"OfferId":"1","OrderValue":"67","HostingTypeID":"3"}], [{"OfferId":"1","OrderValue":"99","HostingTypeID":"6"}], [{"OfferId":"1","OrderValue":"10","HostingTypeID":"8"}]] .Net Object public class JsonFeaturedOffer { public string OfferId { get; set; } public string OrderValue { get; set; } public string HostingTypeID { get; set; } } Converstion code in code behind file byte[] byteArray = Encoding.ASCII.GetBytes(HdnJsonData.Value); MemoryStream stream = new MemoryStream(byteArray); DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(JsonFeaturedOffer)); object result= serializer.ReadObject(stream); JsonFeaturedOffer jsonObj = result as JsonFeaturedOffer; While converting i am getting following error: Expecting element 'root' from namespace ''..

  • How to make Delphi Prism indexed properties visible to C# when properties are not default

    - by Arcturus
    I have several Delphi Prism classes with indexed properties that I use a lot on my C# web applications (we are migrating a big Delphi Win32 system to ASP.Net). My problem is that it seems that C# can't see the indexed properties if they aren't the default properties of their classes. Maybe I'm doing something wrong, but I'm completely lost. I know that this question looks a lot like a bug report, but I need to know if someone else knows how to solve this before I report a bug. If I have a class like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; default; // make IndexedBool the default property end; I can use this class in C# like this: var myObj = new TMyClass(); myObj[0] = true; However, if TMyClass is defined like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; // IndexedBool is not the default property anymore end; Then the IndexedBool property becomes invisible in C#. The only way I can use it is doing this: var myObj = new TMyClass(); myObj.set_IndexedBool(0, true); I don't know if I'm missing something, but I can't see the IndexedBool property if I remove the default in the property declaration. Besides that, I'm pretty sure that it is wrong to have direct access to a private method of a class instance. Any ideas?

  • .NET Remoting Exception not handled Client-Side

    - by DanJo519
    I checked the rest of the remoting questions, and this specific case did not seem to be addressed. I have a .NET Remoting server/client set up. On the server side I have an object with a method that can throw an exception, and a client which will try to call that method. Server: public bool MyEquals(Guid myGuid, string a, string b) { if (CheckAuthentication(myGuid)) { logger.Debug("Request for \"" + a + "\".Equals(\"" + b + "\")"); return a.Equals(b); } else { throw new AuthenticationException(UserRegistryService.USER_NOT_REGISTERED_EXCEPTION_TEXT); } } Client: try { bool result = RemotedObject.MyEquals(myGuid, "cat", "dog"); } catch (Services.Exceptions.AuthenticationException e) { Console.WriteLine("You do not have permission to execute that action"); } When I call MyEquals with a Guid which causes CheckAuthentication to return false, .NET tries to throw the exception and says the AuthenticationException was unhandled. This happens server side. The exception is never marshaled over to the client-side, and I cannot figure out why. All of the questions I have looked at address the issue of an exception being handled client-side, but it isn't the custom exception but a base type. In my case, I can't even get any exception to cross the remoting boundary to the client. Here is a copy of AuthenticationException. It is in the shared library between both server and client. [Serializable] public class AuthenticationException : ApplicationException, ISerializable { public AuthenticationException(string message) : base(message) { } public AuthenticationException(SerializationInfo info, StreamingContext context) : base(info, context) { } #region ISerializable Members void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context) { base.GetObjectData(info, context); } #endregion }

  • Failed sending bytes array to JAX-WS web service on Axis

    - by user304309
    Hi I have made a small example to show my problem. Here is my web-service: package service; import javax.jws.WebMethod; import javax.jws.WebService; @WebService public class BytesService { @WebMethod public String redirectString(String string){ return string+" - is what you sended"; } @WebMethod public byte[] redirectBytes(byte[] bytes) { System.out.println("### redirectBytes"); System.out.println("### bytes lenght:" + bytes.length); System.out.println("### message" + new String(bytes)); return bytes; } @WebMethod public byte[] genBytes() { byte[] bytes = "Hello".getBytes(); return bytes; } } I pack it in jar file and store in "axis2-1.5.1/repository/servicejars" folder. Then I generate client Proxy using Eclipse for EE default utils. And use it in my code in the following way: BytesService service = new BytesServiceProxy(); System.out.println("Redirect string"); System.out.println(service.redirectString("Hello")); System.out.println("Redirect bytes"); byte[] param = { (byte)21, (byte)22, (byte)23 }; System.out.println(param.length); param = service.redirectBytes(param); System.out.println(param.length); System.out.println("Gen bytes"); param = service.genBytes(); System.out.println(param.length); And here is what my client prints: Redirect string Hello - is what you sended Redirect bytes 3 0 Gen bytes 5 And on server I have: ### redirectBytes ### bytes lenght:0 ### message So byte array can normally be transfered from service, but is not accepted from the client. And it works fine with strings. Now I use Base64Encoder, but I dislike this solution.

  • Really slow obtaining font metrics.

    - by Artur
    So the problem I have is that I start my application by displaying a simple menu. To size and align the text correctly I need to obtain font metrics and I cannot find a way to do it quickly. I tested my program and it looks like whatever method I use to obtain font metrics the first call takes over 500 milliseconds!? Because of it the time it takes to start-up my application is much longer than necessary. I don't know if it is platform specific or not, but just in case, I'm using Mac OS 10.6.2 on MacBook Pro (hardware isn't an issue here). If you know a way of obtaining font metrics quicker please help. I tried these 3 methods for obtaining the font metrics and the first call is always very slow, no matter which method I choose. import java.awt.Font; import java.awt.FontMetrics; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.font.FontRenderContext; import java.awt.font.LineMetrics; import javax.swing.JFrame; public class FontMetricsTest extends JFrame { public FontMetricsTest() { setVisible(true); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } @Override public void paint(Graphics g) { Graphics2D g2 = (Graphics2D) g; Font font = new Font("Dialog", Font.BOLD, 10); long start = System.currentTimeMillis(); FontMetrics fontMetrics = g2.getFontMetrics(font); // LineMetrics fontMetrics1 = // font.getLineMetrics("X", new FontRenderContext(null, false, false)); // FontMetrics fontMetrics2 = g.getFontMetrics(); long end = System.currentTimeMillis(); System.out.println(end - start); g2.setFont(font); } public static void main(String[] args) { new FontMetricsTest(); } }
