  • Hidden Features of C#?

    - by Serhat Özgel
    This came to my mind after I learned the following from this question: where T : struct We, C# developers, all know the basics of C#. I mean declarations, conditionals, loops, operators, etc. Some of us even mastered the stuff like Generics, anonymous types, lambdas, linq, ...

  • WPF Databinding CheckBox.IsChecked

    - by Adam Tegen
    How would I bind the IsChecked member of a CheckBox to a member variable in my form? (I realize I can access it directly, but I am trying to learn about databinding and WPF) Below is my failed attempt to get this working. XAML: <Window x:Class="MyProject.Form1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Title" Height="386" Width="563" WindowStyle="SingleBorderWindow"> <Grid> <CheckBox Name="checkBoxShowPending" TabIndex="2" Margin="0,12,30,0" Checked="checkBoxShowPending_CheckedChanged" Height="17" VerticalAlignment="Top" HorizontalAlignment="Right" Width="92" Content="Show Pending" IsChecked="{Binding ShowPending}"> </CheckBox> </Grid> </Window> Code: namespace MyProject { public partial class Form1 : Window { private ListViewColumnSorter lvwColumnSorter; public bool?

  • No OpenID endpoint found

    - by azamsharp
    I am trying to use the DotNetOpenId library to add OpenID support on a test website. For some reason it keeps giving me the following error when running on FireFix. Keep in mind that I am using localhost as I am testing it on my local machine. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using DotNetOpenAuth.OpenId.Extensions.ProviderAuthenticationPolicy; using DotNetOpenAuth.OpenId.Extensions.SimpleRegistration; using DotNetOpenAuth.OpenId.RelyingParty; namespace TableSorterDemo { public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var openid = new OpenIdRelyingParty(); if (openid.GetResponse() != null) { switch (openid.GetResponse().Status) { case AuthenticationStatus.Authenticated: var fetch = openid.GetResponse().GetExtension(typeof(ClaimsResponse)) as ClaimsResponse; var nick = fetch.Nickname; var email = fetch.Email; break; } } } protected void OpenIdLogin1_LoggedIn(object sender, OpenIdEventArgs e) { var openid = new OpenIdRelyingParty(); if(openid.GetResponse() != null) { switch(openid.GetResponse().Status) { case AuthenticationStatus.Authenticated: var fetch = openid.GetResponse().GetExtension(typeof (ClaimsResponse)) as ClaimsResponse; var nick = fetch.Nickname; var email = fetch.Email; break; } } } protected void OpenIdLogin1_LoggingIn(object sender, OpenIdEventArgs e) { var openid = new OpenIdRelyingParty(); var req = openid.CreateRequest(OpenIdLogin1.Text); var fetch = new ClaimsRequest(); fetch.Email = DemandLevel.Require; fetch.Nickname = DemandLevel.Require; req.AddExtension(fetch); req.RedirectToProvider(); return; } } } Also, if I run the same page in Chrome then I get the following: Login failed: This message has already been processed. This could indicate a replay attack in progress.

  • EF 4, POCO and AddOrUpdate

    - by Eric J.
    I'm trying to create a method on an EF 4 POCO repository called AddOrUpdate. The idea is that the business layer can pass in a POCO object and the persistence framework will add the object if it is new (not yet in the database), else will update the database (once SaveChanges() is called) with the new value. This is similar to some other questions I have asked about EF, but I'm only about 80% there in understanding this so please forgive partial duplication. The part I'm missing is how to update the object graph in my ObjectContext/associated ObjectSet for the passed-in business object once I have determined that the business object indeed already exists in the database (and now has been loaded thanks to TryGetObjectByKey). ApplyCurrentValues sounds sort of like what I want, but it only copies scalar values and doesn't seem intended to update the object graph in the ObjectContext/ObjectSet. Because of my particular use case I don't care about concurrency right now. public void AddOrUpdate(BO biz) { object obj; EntityKey ek = Ctx.CreateEntityKey(mySetName, biz); bool found = Ctx.TryGetObjectByKey(ek, out obj); if (found) { // How do I do what this method name implies? Biz is a parent with children. mySet.TellTheSetToUpdateThisObject(biz); } else { mySet.AddObject(biz); } Ctx.DetectChanges(); }

  • wpf 4.0 datagrid template column two-way binding problem

    - by rouwlee
    Hello all! I'm using the datagrid from wpf 4.0. This has a TemplateColumn containing a checkbox. The IsChecked property of the checkbox is set via binding. The problem is that even if I specify the binding mode explicitly to be TwoWay, it works only in one direction. I have to mention that the same code works perfectly in .net 3.5 with the datagrid from the wpf toolkit. Please take a look at the .xaml and .cs contents. Thanks in advance, Roland <Window.Resources> <DataTemplate x:Key="IsSelectedColumnTemplate"> <CheckBox IsChecked="{Binding Path=IsSelected, Mode=TwoWay}" /> </DataTemplate> </Window.Resources> <Grid> <DataGrid x:Name="dataGrid" AutoGenerateColumns="false" CanUserAddRows="False" CanUserDeleteRows="False" HeadersVisibility="Column" ItemsSource="{Binding}" > <DataGrid.Columns> <DataGridTemplateColumn Header="Preselected" x:Name="myIsSelectedColumn" CellTemplate="{StaticResource IsSelectedColumnTemplate}" CanUserSort="True" SortMemberPath="Orientation" Width="Auto" /> </DataGrid.Columns> </DataGrid> </Grid> and the related .cs content: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); ObservableCollection<DataObject> DataSource = new ObservableCollection<DataObject>(); DataSource.Add(new DataObject()); dataGrid.ItemsSource = DataSource; } } public class DataObject : DependencyObject { public bool IsSelected { get { return (bool)GetValue(IsSelectedProperty); } set { SetValue(IsSelectedProperty, value); } } // Using a DependencyProperty as the backing store for IsSelected. This enables animation, styling, binding, etc... public static readonly DependencyProperty IsSelectedProperty = DependencyProperty.Register("IsSelected", typeof(bool), typeof(DataObject), new UIPropertyMetadata(false, OnIsSelectedChanged)); private static void OnIsSelectedChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e) { // this part is not reached } }

  • ASP.NET MVC search box: use modal popup or inline div or redirect to another page?

    - by JK
    I have a view with a textbox and a search button, eg CustomerTextBox and CustomerSearchButton. The list of customers is too long to display in a dropdown, and there has to be advanced search functions anyway. What is the best practice in MVC to handle this case? When the user clicks on the search button, should it: A. Load another view into a modal popup (eg /customers/search)? How would you do this in MVC, just set popupWindow.location.href = '/customers/search'? How would you return the value to the main view? B. Have the search form in a hidden div that expands when the search button is clicked? How would be done? a partial view maybe? C. Redirect the user to a search page by means of RedirectTo("/customers/search")? How would you return the value to the main class? I've only been doing MVC for 3 days so thanks to those who answer my questions that might have quite obvious answers that I cant see yet. :)

  • Problem with ScriptManager.RegisterStartupScript in WebControl nested in UpdatePanel

    - by Chris
    Hello, I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page. The control (and one or two others) are nested inside an UpdatePanel. They are inserted onto the page onto a PlaceHolder: <asp:UpdatePanel ID="pnlAjax" runat="server"> <ContentTemplate> <asp:PlaceHolder ID="placeholder" runat="server"> </asp:PlaceHolder> ... protected override void OnInit(EventArgs e){ placeholder.Controls.Add(Factory.CreateControl()); base.OnInit(e); } This is the only update panel on the page. The control requires some initial javascript be run for it to work correctly. The control calls: ScriptManager.RegisterStartupScript(this, GetType(), Guid.NewGuid().ToString(), script, true); and I have also tried: ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), script, true); The problem is that the script runs correctly when the page is first displayed, but does not re-run after a partial postback. I have tried the following: Calling RegisterStartupScript from CreateChildControls Calling RegisterStartupScript from OnLoad / OnPreRender Using different combinations of parameters for the first two parameters (in the example above the Control is Page and Type is GetType(), but I have tried using the control itself, etc). I have tried using persistent and new ids (not that I believe this should have a major impact either way). I have used a few breakpoints and so have verified that the Register line is being called correctly. The only thing I have not tried is using the UpdatePanel itself as the Control and Type, as I do not believe the control should be aware of the update panel (and in any case there does not seem to be a good way of getting the update panel?). Can anyone see what I might be doing wrong in the above? Thanks :)

  • Geting SelectList to MVC view using AJAX/jQuery

    - by Chris
    Hi all. I have a C# MVC application which is populating a dropdown based on a date selected. Once the date is selected I am sending it to an action via AJAX/jQuery. The action gets a list of items to return for that date. Here is where my problem is. I have done it previously where I render a partial view from the action and pass it the SelectList as the model. However, I really just want to do it inline in the original view, so I'm hoping there is some way I can return the SelectList and from there do some magic Javascript/JQuery to put it into a dropdown. Has anybody ever done this before? If so, what do I on the client end after calling the load() to return the SelectList? I've done something like this previously, when I was just returning a string or other value to be rendered as straight text: $("#returnTripRow").load("/Trip.aspx/GetTripsForGivenDate?date=" + escape(selection)); But I'm not sure how to intercept the data and morph it into am Html.DropDown() call, or equivalent. Any ideas? Thanks, Chris

  • Delphi label and asm weirdness?

    - by egon
    I written an asm function in Delphi 7 but it transforms my code to something else: function f(x: Cardinal): Cardinal; register; label err; asm not eax mov edx,eax shr edx, 1 and eax, edx bsf ecx, eax jz err mov eax, 1 shl eax, cl mov edx, eax add edx, edx or eax, edx ret err: xor eax, eax end; // compiled version f: push ebx // !!! not eax mov edx,eax shr edx, 1 and eax, edx bsf ecx, eax jz +$0e mov eax, 1 shl eax, cl mov edx, eax add edx, edx or eax, edx ret err: xor eax, eax mov eax, ebx // !!! pop ebx // !!! ret // the almost equivalent without asm function f(x: Cardinal): Cardinal; var c: Cardinal; begin x := not x; x := x and x shr 1; if x <> 0 then begin c := bsf(x); // bitscanforward x := 1 shl c; Result := x or (x shl 1) end else Result := 0; end; Why does it generate push ebx and pop ebx? And why does it do mov eax, ebx? It seems that it generates the partial stack frame because of the mov eax, ebx. This simple test generates mov eax, edx but doesn't generate that stack frame: function asmtest(x: Cardinal): Cardinal; register; label err; asm not eax and eax, 1 jz err ret err: xor eax, eax end; // compiled asmtest: not eax and eax, $01 jz +$01 ret xor eax, eax mov eax, edx // !!! ret It seems that it has something to do with the label err. If I remove that I don't get the mov eax, * part. Why does this happen? Made a bug report on Quality Central.

  • asp.net mvc2 - controller for master page?

    - by ile
    I've just finished my first ASP.NET MVC (2) CMS. Next step is to build website that will show data from CMS's database. This is website design: #1 (Red box) - displays article categories. ViewModel: public class CategoriesDisplay { public CategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } #2 (Brown box) - displays last x articles; skips those from green box #3. Viewmodel: public class ArticleDisplay { public ArticleDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } public int ArticleID { set; get; } public string ArticleTitle { set; get; } public string URLArticleTitle { set; get; } public DateTime ArticleDate; public string ArticleContent { set; get; } } #3 (green box) - Displays last x articles. Uses the same ViewModel as brown box #2 #4 (blue box) - Displays list of upcoming events. Uses dataContext.Model.Event as ViewModel Boxes #1, #2 and #4 will repeat all over the site and they are part of Master Page. So, my question is: what is the best way to transfer this data from Model to Controller and finally to View pages? Should I make a controller for master page and ViewModel class that will wrap all this classes together OR Should I create partial Views for every of these boxes and make each of them inherit appropriate class (if it is even possible that it works this way?) OR Should I put this repeated code in all controllers and all additional data transfer via ViewData, which would be probably the worse way :) OR There is maybe a better and more simple way but I don't know/see it? Thanks in advance, Ile

  • Silverlight 2 Error Code: 4004

    - by jkidv
    Hey guys/gals. I have a silverlight 2 app that has an ObservableCollection of a class from a separate assem/lib. When I set my ListBox.ItemsSource on that collection, and run it, I get the error code: 4004 "System.ArgumentException: Value does not fall within the expected range." Here is part of the code: public partial class Page : UserControl { ObservableCollection<Some.Lib.Owner> ooc; public Page() { ooc = new ObservableCollection<Some.Lib.Owner>(); Some.Lib.Owner o1 = new Some.Lib.Owner() { FirstName = "test1" }; Some.Lib.Owner o2 = new Some.Lib.Owner() { FirstName = "test2" }; Some.Lib.Owner o3 = new Some.Lib.Owner() { FirstName = "test3" }; ooc.Add(o1); ooc.Add(o2); ooc.Add(o3); InitializeComponent(); lb1.ItemsSource = ooc; } } But when I create the Owner class within this same project, everything works fine. Is there some security things going on behind the scenes? Also, I'm using the generate a html page option and not the aspx option, when I created this Silverlight 2 app.

    I have been following the following post on using multiple ItemTemplates in a ListView control.

  • ASP.net DAL DatasSet and Table Adapter not in namespace - Northwind Tutorial

    - by Alan
    I've been attempting to walk through the "Creating a Data Access Layer" tutorial found http://www.asp.net/learn/data-access/tutorial-01-cs.aspx I create the DB connection, create the typed dataset and table adapter, specify the sql, etc. When I add the code to the presentation layer (in this case a page called AllProducts.aspx) I am unable to find the NorthwindTableAdapters.ProductsTableAdapter class. I tried to import the NorthwindTableAdapters namespace, but it is not showing up. Looking in the solution explorer Class View confirms that there is a Northwind class, but not the namespace I'm looking for. I've tried several online tutorials that all have essentially the same steps, and I'm getting the same results. Can anyone give me a push in the right direction? I'm getting error: Namespace or type specified in the Imports 'NorthwindTableAdapters' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. I think I might need to add a reference OR they may be creating a separate class and importing it into their main project. If that's the case, the tutorials do not mention this.

  • Mapping and metadata information could not be found for EntityType Exception

    - by dcompiled
    I am trying out ASP.NET MVC Framework 2 with the Microsoft Entity Framework and when I try and save new records I get this error: Mapping and metadata information could not be found for EntityType 'WebUI.Controllers.PersonViewModel' My Entity Framework container stores records of type Person and my view is strongly typed with class PersonViewModel which derives from Person. Records would save properly until I tried to use the derived view model class. Can anyone explain why the metadata class doesnt work when I derive my view model?

  • ExtJS: Autoscroll vertical FormPanels added to panel

    - by Sarge
    Hi All, I'm writing an app where I have a BorderLayout for the entire page. In the south part I have a Panel to which I add FormPanels. I would like to be able to scroll that Panel so I can scroll through the FormPanels. So far, nothing I've found from searches has helped. I don't quite understand what ExtJS requires in terms of the combination of LayoutManagers, setting the size and setting AutoScroll. Any partial tips will be gratefully followed up. A code snippet: createTrailJunctionPanel = function(trailJunction) { var trailJunctionPanel = new Ext.form.FormPanel({ labelWidth: 75, width: 350, defaultType: 'textfield', items: [{ fieldLabel: 'Junction Name', name: 'junction-name' }], autoScroll:true, //anchor: '100% 100%', height: 100 }); matchedTrailJunctionsPanel.add(trailJunctionPanel); if(trailJunction.publicTrailSegments.length == 0) { matchedTrailJunctionsPanel.add(new Ext.form.Label({text: 'No public trails matched'})); } else { var grid = new Ext.grid.GridPanel({ store: mapMatchObjectStore, columns: [ {id:'publicTrailSegment',header: 'Trail', width: 160, sortable: true, dataIndex: 'publicTrailSegment'} ], stripeRows: true, autoExpandColumn: 'publicTrailSegment', height: 350, width: 600, title: 'Matched Trail Junctions' }); matchedTrailJunctionsPanel.add(grid); } matchedTrailJunctionsPanel.doLayout(); } matchedTrailJunctionsPanel = new Ext.Panel({ title: "Matched Trail Junctions2", id: "matched-trail-junctions", autoScroll:true //layout: 'anchor' });

  • Create an ASMX web service from a WSDL file

    - by metanaito
    I have a WSDL file and I am trying to create a web service that conforms to the WSDL. I've created clients using WSDL files that consume an existing service, but I've never created a web service that needed to follow a specific WSDL. I've gone as far as using: wsdl.exe mywsdl.wsdl /l:VB /serverInterface Now I've got a .vb file generated from that WSDL. However I am not sure what I'm supposed to do with this VB file. It looks like it's got a public interface in there but no class that implements the interface. It also has a bunch of partial classes for the types in the WSDL. I was expecting there to be some sort of stub where I put in the code to complete the service calls. I've only created simple web services before and none of them used public interfaces so I'm unfamiliar with what is going on here. At this point I'm not sure how I use the generated .vb file and make it work with an .asmx file and what additional coding is needed to complete the interface.

  • Unable to debug XBAP with Visual Studio 2010

    - by Oleg I.
    Just migrated my project to Visual Studio 2010, but target framework was left 3.5. Project contains an XBAP app in partial trust and a bunch of WCF services. Debugging is configured to start PresentationHost.exe with -debug and -debugSecurityZoneUrl parameters. Under VS2008 everything works fine, and in VS2010 Beta2 (don't sure about RC), but under VS2010 RTM debugging is for some reason doesn't working. Application runs, but doesn't hit any breakpoint. And if for example exception occurs, message box appears "Do you wish to debug or close..." and after I choose "debug" option new weird message box appears: --------------------------- Warning --------------------------- A debugger is attached to PresentationHost.exe but not configured to debug this unhandled exception. To debug this exception, detach the current debugger. An unhandled exception was raised from Microsoft .NET Framework v 1.0, 1.1, or 2.0, but the current debugger is configured to debug Microsoft .NET Framework v4.0 code. Examine the exception using the SOS tool. --------------------------- OK --------------------------- And where is the vaunted multitargeting? Did anyone have already bumped into same issue? UPDATE: Tried to debug with "Start browser with URL" option. Debugging is working, but I get SecurityException. So it is possible, just need to figure out how to make it work with "Start external program" option. UPDATE2: Checked what PresentationHost is actually loads in both scenarios: "Start external program" - Latest version (4.0.31106.0) from C:\Windows\System32\ "Start browser with URL" - Old version (3.0.6920.4902) from C:\Windows\winsxs\x86_wpf-presentationhostexe_31bf3856ad364e35_6.1.7600.16385_none_6fca8974817173aa

  • jQuery AJAX request (Rails 3) gets redirected and returns empty message body (only with SSL)!

    - by elsurudo
    I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas? Edit: I now see that the first request redirects, and the proper partial gets rendered on the redirect. However, the 2nd response's body (on the client-side) is still empty. I'm guessing jQuery uses the first response and doesn't have a listener set up for the redirect. How do I get around this? Also, another note: the page doing the requesting is an HTTPS page. Here is what my log says: Started GET "/plans/221168073" for 127.0.0.1 at Tue Jun 15 01:24:06 -0400 2010 Processing by PlansController#show as HTML Parameters: {"id"=>"221168073"} DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead. (called from ensure_proper_protocol at /Users/ernestsurudo/Sites/vidfolia/vendor/plugins/ssl_requirement/lib/ssl_requirement.rb:57) Redirected to http://vidfolia.com/plans/221168073 Completed 302 Found in 1ms It turns out that if I turn off SSL requirement for that page, it works! I still have no idea why, though. So I suppose my question is: what is the workaround?

  • Binding property to Silverlight dependency property independent of DataContext

    - by Simon_Weaver
    I'm trying to make an Address control that has an IsReadOnly property, which will make every TextBox inside read only when set to true. <my:AddressControl Grid.Column="1" Margin="5" IsReadOnly="True"/> I've managed to do this just fine with a dependency property and it works. Here's a simple class with the dependency property declared : public partial class AddressControl : UserControl { public AddressControl() { InitializeComponent(); this.DataContext = this; } public static readonly DependencyProperty IsReadOnlyProperty = DependencyProperty.Register("IsReadOnly", typeof(bool), typeof(AddressControl), null); public bool IsReadOnly { get { return (bool)GetValue(IsReadOnlyProperty); } set { SetValue(IsReadOnlyProperty, value); } } } In the XAML for this codebehind file I have a Textbox for each address line: <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding City, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding State, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding Zip, Mode=TwoWay}"/> Like i said this works just fine. The problem is that the Address control itself is bound to its parent object (I have several addresses I am binding). <my:AddressControl DataContext="{Binding ShippingAddress, Mode=TwoWay}" IsReadOnly="True"> <my:AddressControl DataContext="{Binding BillingAddress, Mode=TwoWay}" IsReadOnly="True"> The problem is that as soon as I set DataContext to something other than 'this' then the binding for IsReadOnly breaks. Not surprising because its looking for IsReadOnly on the Address data entity and it doesn't exist or belong there. I've tried just about every combination of binding attributes to get IsReadOnly to bind to the AddressControl obejct but can't get it working. I've tried things like this, but I can't get IsReadOnly to bind independently to the AddressControl property instead of its DataContext. <TextBox IsReadOnly="{Binding RelativeSource={RelativeSource Self}, Path=IsReadOnlyProperty}" Text="{Binding City, Mode=TwoWay}" /> I think I'm pretty close. What am I doing wrong?

  • Correct way to import Blueprint's ie.css via DotLess in a Spark view

    - by Chris F
    I am using the Spark View Engine for ASP.NET MVC2 and trying to use Blueprint CSS. The quick guide to Blueprint says to add links to the css files like so: <link rel="stylesheet" href="blueprint/screen.css" type="text/css" media="screen, projection"> <link rel="stylesheet" href="blueprint/print.css" type="text/css" media="print"> <!--[if lt IE 8]><link rel="stylesheet" href="blueprint/ie.css" type="text/css" media="screen, projection"><![endif]--> But I'm using DotLess and wish to simplify Blueprint as suggested here. So I'm doing this in my site.less (which gets compiled to site.min.css by Chirpy): @import "screen.css"; #header { #title { .span-10; .column; } } ... Now my site can just reference site.min.css and it includes blueprint's screen.css, which includes my reset. I can also tack on an @import "print.css" after my @import "screen.css" if desired. But now, I'm trying to figure out the best way to bring in the ie.css file to have Blueprint render correctly in IE6 & IE7. In my Spark setup, I have a partial called _Styles.spark that is brought into the Application.spark and is passed a view model that includes the filenames for all stylesheets to include (and an HtmlExtension to get the full path) and they're added using an "each" iterator. <link each="var styleSheet in Model.Styles" href="${Html.Stylesheet(styleSheet)}" rel="stylesheet" type="text/css" media="all"/> Should I simply put this below the above line in my _Styles.spark file? <!--[if lt IE 8]><link rel="stylesheet" href="${Html.Stylesheet("ie.css")}" type="text/css" media="screen, projection"><![endif]--> Will Spark even process it because it's surrounded by a comment?

  • C# Web Reference and PHP

    - by Louis
    I am attempting to call a Web Service (created in PHP) from my C# application. I have successfully added the Web Reference in Visual Studios, however I cannot figure out exactly how to invoke the call to the web service. I have been following this tutorial: http://sanity-free.org/article25.html however when I try and compile I get a "The type or namespace name 'SimpleService' could not be found". My C# code is as follows: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.IO; namespace inVision_OCR { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void translateButton_Click(object sender, EventArgs e) { // We need to snap the image here somehow . . . // Open up the image and read its contents into a string FileStream file = new FileStream("\\Hard Disk\\ocr_images\\test.jpg", FileMode.Open); StreamReader sr = new StreamReader(file); string s = sr.ReadToEnd(); sr.Close(); // Using SOAP, pass this message to our development server SimpleService svc = new SimpleService(); string s1 = svc.getOCR("test"); MessageBox.Show(s); } } } Any help would be appreciated.

  • wpf datagrid current item binding

    - by tk
    I want to bind a content of Label to the selected item of a datagrid. I thought the 'current item' binding expression would work, but it is not. My xaml code and code-behind c# is like below. <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="512" Width="847"> <DockPanel LastChildFill="True"> <Label Content="{Binding Data/colA}" DockPanel.Dock="Top" Height="30"/> <DataGrid ItemsSource="{Binding Data}"></DataGrid> </DockPanel> </Window> namespace WpfApplication2 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); this.DataContext = new MyData(); } } public class MyData { DataTable data; public MyData() { data = new DataTable(); data.Columns.Add("colA"); data.Columns.Add("colB"); data.Rows.Add("aa", 1); data.Rows.Add("bb", 2); } public DataTable Data { get { return data; } } } } The label shows the first item of the DataTable, and does not change when i select other items on the datagrid. It seems the current item of dataview does not change. What should i do to bind it to the current selected item of datagrid?
