  • How to: WCF XML-RPC client?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  • Why is two-way binding in silverlight not working?

    - by Edward Tanguay
    According to how Silverlight TwoWay binding works, when I change the data in the FirstName field, it should change the value in CheckFirstName field. Why is this not the case? ANSWER: Thank you Jeff, that was it, for others: here is the full solution with downloadable code. XAML: <StackPanel> <Grid x:Name="GridCustomerDetails"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="300"/> </Grid.ColumnDefinitions> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="0" Grid.Column="0">First Name:</TextBlock> <TextBox Margin="10" Grid.Row="0" Grid.Column="1" Text="{Binding FirstName, Mode=TwoWay}"/> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="1" Grid.Column="0">Last Name:</TextBlock> <TextBox Margin="10" Grid.Row="1" Grid.Column="1" Text="{Binding LastName}"/> <TextBlock VerticalAlignment="Center" Margin="10" Grid.Row="2" Grid.Column="0">Address:</TextBlock> <TextBox Margin="10" Grid.Row="2" Grid.Column="1" Text="{Binding Address}"/> </Grid> <Border Background="Tan" Margin="10"> <TextBlock x:Name="CheckFirstName"/> </Border> </StackPanel> Code behind: public Page() { InitializeComponent(); Customer customer = new Customer(); customer.FirstName = "Jim"; customer.LastName = "Taylor"; customer.Address = "72384 South Northern Blvd."; GridCustomerDetails.DataContext = customer; Customer customerOutput = (Customer)GridCustomerDetails.DataContext; CheckFirstName.Text = customer.FirstName; }

  • Can a grails controller extend from a base class? How to make it so grails doesn't blow up?

    - by egervari
    I wrote a base class to help build my controllers more quickly and to remove duplication. It provides some helper methods, default actions and some meta programming to make these things easier to build. One of those methods in the base class is like this: def dynamicList(Class clazz) { def model = new LinkedHashMap() model[getMapString(clazz) + "s"] = list(clazz) model[getMapString(clazz) + "sTotal"] = count(clazz) model } The action that calls it, also in the base class, is this: def list = { dynamicList(clazz) } Unfortunately, when I go to list action in the controller subclass that inherits the base class when my application is deployed, I get this exception: groovy.lang.MissingMethodException: No signature of method: groovy.lang.MissingMethodException.dynamicList() is applicable for argument types: (java.lang.Class) values: [class project .user.User] at project.user.UserController$_closure1.doCall(UserController.groovy:18) at project.user.UserController$_closure1.doCall(UserController.groovy) at java.lang.Thread.run(Thread.java:619) How can I hit grails over the head and just tell it do what I want it to do? My controller unit tests run just fine, so grails' run-time is totally at fault :/ Ken

  • Creating a column of RadioButtons in Adobe Flex

    - by adnan
    I am having an un-predictable behavior of creating radio buttons in advancedDataGrid column using itemRenderer. Similar kind of problem has been reported at http://stackoverflow.com/questions/112036/creating-a-column-of-radiobuttons-in-adobe-flex. I tried to use the same procedure i.e. bind every radio button selectedValue and value attributes with the property specified in the property of the associated bean but still facing the problem. The button change values! The selected button becomes deselected, and unselected ones become selected. Here is the code of my advancedDataGrid: <mx:AdvancedDataGrid id="adDataGrid_rptdata" width="100%" height="100%" dragEnabled="false" sortableColumns="false" treeColumn="{action}" liveScrolling="false" displayItemsExpanded="true" > <mx:dataProvider> <mx:HierarchicalData source="{this.competenceCollection}" childrenField="competenceCriteria"/> </mx:dataProvider> <mx:columns> <mx:AdvancedDataGridColumn headerText="" id="action" dataField="criteriaName" /> <mx:AdvancedDataGridColumn headerText="Periode 1" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period1" value="{data}" selected="{data.period1}" group="{data.radioBtnGrpArray[0]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 2" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period2" value="{data}" selected="{data.period2}" group="{data.radioBtnGrpArray[1]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> <mx:AdvancedDataGridColumn headerText="Periode 3" dataField="" width="200"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center" width="100%" verticalAlign="middle"> <mx:RadioButton name="period3" value="{data}" selected="{data.period3}" group="{data.radioBtnGrpArray[2]}" visible="{data.showRadioButton}" /> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:AdvancedDataGridColumn> </mx:columns> </mx:AdvancedDataGrid> Any work around is highly appreciated in this regard!

  • How to conditionally execute a jquery validation?

    - by Pandiya Chendur
    I am validating form using jquery validation plugin...... rules: { Name: "required", MobileNo: { required: true, minlength: 10, remote: '<%=Url.Action("getClientMobNo", "Clients") %>' }, Address: "required" }, messages: { Name: "please provide a client name", MobileNo: { required: "Please provide a mobile phone no", rangelength: jQuery.format("Enter at least {0} characters"), remote: jQuery.format("This MobileNo is already in use") }, Address: "please provide client address" }, This works pretty well on add form validation but i use the same form for edit here they can use the same mobile no,but my plugin validates that mobileno saying there is already a mobileno... But how to execute remote attribute based on a condition, MobileNo: { required: true, minlength: 10, if($("#HfId").val() == ""){ remote: '<%=Url.Action("getClientMobNo", "Clients") %>' } }, Is this a valid jquery conditional validation statement.... How to skip remote attribute based on a condition....

  • Resharper and var

    - by Refracted Paladin
    I have Resharper 4.5 and have found it invaluable so far but I have a concern; It seems to want to make every variable declaration implicit(var). As a relativly new developer how much should I trust ReSharper when it comes to this? Take the below code snippet from a method that Paints Tab Headers. TabPage currentTab = tabCaseNotes.TabPages[e.Index]; Rectangle itemRect = tabCaseNotes.GetTabRect(e.Index); SolidBrush fillBrush = new SolidBrush(Color.Linen); SolidBrush textBrush = new SolidBrush(Color.Black); StringFormat sf = new StringFormat { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center }; Resharper wants me to change all 5 of those to var. I have read the following similar post,Use of var keyword in C#, but I would like to know from a Resharper standpoint. Thanks!

  • Ruby on Rails: What are partial hash arguments and full set arguments?

    - by williamjones
    I'm using asserts_redirected_to in my unit tests, and I'm receiving this warning: DEPRECATION WARNING: Using assert_redirected_to with partial hash arguments is deprecated. Specify the full set arguments instead. What is a partial hash argument, and what is a full set argument? These aren't terms that I've seen used in the Rails community before, and the only relevant results I can find on Google for these are in reference to this deprecation warning. Here is my code: assert_redirected_to :controller => :user, :action => :search also tried: assert_redirected_to({:controller => :user, :action => :search}) I might have guessed that it feels I'm missing some parameters or something like that, but the API documentation explicitly says that not all parameters need to be included: http://rails.rubyonrails.org/classes/ActionController/Assertions/ResponseAssertions.html

  • Why is my UIImageView blurred?

    - by Denis M
    I have a really weird problem with UIImageView. I have an image (an RGB png) 45x45 pixels which I add to the view. I can see that image is blurred after added to the view. Here is the same image in the simulator (left) and in Xcode (right): I have custom UIImageView class with this initWithImage code: - (id) initWithImage:(UIImage*) image { self = [super initWithImage:image]; self.frame = CGRectMake(0, 0, 45, 45); self.contentMode = UIViewContentModeScaleAspectFit; self.quantity = 1; if (self) { self.label = [[UITextField alloc]initWithFrame:CGRectMake(0,40,45,25)]; self.label.font = [UIFont systemFontOfSize:16]; self.label.borderStyle = UITextBorderStyleNone; self.label.enabled = TRUE; self.label.userInteractionEnabled = TRUE; self.label.delegate = self; self.label.keyboardType = UIKeyboardTypeNumbersAndPunctuation; self.label.textAlignment = UITextAlignmentCenter; } self.userInteractionEnabled = TRUE; // Prepare 3 buttons: count up, count down, and delete self.deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.deleteButton.hidden = NO; self.deleteButton.userInteractionEnabled = YES; self.deleteButton.titleLabel.font = [UIFont systemFontOfSize:20]; self.deleteButton.titleLabel.textColor = [UIColor redColor]; [self.deleteButton setTitle:@"X" forState:UIControlStateNormal]; [self.deleteButton addTarget:self action:@selector(deleteIcon:) forControlEvents:UIControlEventTouchUpInside]; self.upCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.upCountButton.hidden = NO; self.upCountButton.userInteractionEnabled = YES; [self.upCountButton setTitle:@"+" forState:UIControlStateNormal]; [self.upCountButton addTarget:self action:@selector(addQuantity:) forControlEvents:UIControlEventTouchUpInside]; self.downCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.downCountButton.hidden = YES; self.downCountButton.userInteractionEnabled = YES; [self.downCountButton setTitle:@"-" forState:UIControlStateNormal]; [self.downCountButton addTarget:self action:@selector(removeQuantity:) forControlEvents:UIControlEventTouchUpInside]; return self; } I create it like this: UIImage *desertIcon = [UIImage imageNamed:@"desert.png"]; IconObj *desertIconView = [[IconObj alloc] initWithImage:desertIcon]; desertIconView.center = CGPointMake(265,VERTICAL_POINT_ICON); desertIconView.type = [IconObj TYPE_DESERT]; [self.view addSubview:desertIconView]; [desertIconView release]; Why would the displayed image be so than the one stored in a file?

The error is consistent and is probablistic: that is, each time I boot I have a certain chance to fail. Actually, I have a slight suspiction on the cause of the failure. Look at the cabling: What kind of engineer does it this way? Nah. Even 1Gbps Ethernet hardly tolerates cables bent over a small angle, and there you have 6Gbps SATA. How cound I determine and fix the cause of errors and/or switch the link to 3Gbps mode permanently?

  • Code for adding Content Controls Word 2007 C#

    - by AProgrammer
    Hey all, I was wondering if anyone has any idea how I can add Content Controls to a Word Document (Office 2007) from the Document Task/Action Pane via C#. The goal is the following: I want to have categorized information in the Task/Action Pane and have the user fill out the info there. Once they have filled out that information they'll click on a button and it will insert content Controls into the Word Document that has that Data. The reason I want to use Content Controls is because the data will be bound to a database. Is this possible? I would like links that do this without WordProcessingML or OpenXML. There has to be a way to do this via server side code and such that doesn't require long blocks of ,, etc. Thanks!

  • Dismissing pickers and keyboards invoked by a UIWebView

    - by Dev Kanchen
    I am implementing an in-app browser using UIWebView, that shows an 'action' button up-top that - when tapped - scales the UIWebView and allows the user to perform some other actions. If, however, at the point of tapping this 'action' button, the user were entering some text on the webview, or using a picker to select an option from a drop-down list, then the webview gets scaled without dismissing the keyboard/picker. Apart from being ugly, this also obscures my main view and controls. So is there a way to make a UIWebView dismiss all associated input controls, such as keyboards/pickers, when asked to? I tried using [myWebView resignFirstResponder] but that didn't work. Any ideas? Thanks.

  • Where's all the XPCOM user documentation?

    - by Graham Paulson
    Google can't find much user documentation for XPCOM. Sure, it can find endless references to making new XPCOM components in C++, but that's utterly useless to anyone who needs to know how to use the existing components from JavaScript. This is a huge gap, occasionally touched on by trivial examples of creating an instance and calling a method. Has nobody with a more in-depth knowledge of the componentry written anything about its use? Using components with multiple interfaces? Implementing listeners for handling asynchronous behaviour? "Rapid Application Development with Mozilla" is no help (great breadth but little depth). Spotty references that exist to the defunct XULPlanet redirect to Mozilla Development Center, but that's pretty useless. Mozilla Development Center articles point back to XULPlanet, which is a joke. Is this the best an army of open source advocates can muster to promote the extension of The Beast?

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

    Hey all, I made a very simple application to start playing around with Android development.

  • Escaping ampersands in URLs for HttpClient requests

    - by jpatokal
    So I've got some Java code that uses Jakarta HttpClient like this: URI aURI = new URI( "http://host/index.php?title=" + title + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery()); The problem is that if title includes any ampersands (&), they're considered parameter delimiters and the request goes screwy... and if I replace them with the URL-escaped equivalent %26, then this gets double-escaped by getEscapedPathQuery() into %2526. I'm currently working around this by basically repairing the damage afterward: URI aURI = new URI( "http://host/index.php?title=" + title.replace("&", "%26") + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery().replace("%2526", "%26")); But there has to be a nicer way to do this, right? Note that the title can contain any number of unpredictable UTF-8 chars etc, so escaping everything else is a requirement.

  • Joomla - Force File Download / CSV Export

    - by lautaro.dragan
    I'm in need of help... this is my first time asking a question in SO, so please be kind :) I'm trying to force-download a file from php, so when the user hits a certain button, he gets a file download. The file is a csv (email, username) of all registered users. I decided to add this button to the admin users screen, as you can see in this screenshot. So I added the following code to the addToolbar function in administrator/components/com_users/views/users/view.html.php: JToolBarHelper::custom('users.export', 'export.png', 'export_f2.png', 'Exportar', false); This button is mapped to the following function in the com_users\controller\users.php controller: public function exportAllUsers() { ob_end_clean(); $app = JFactory::getApplication(); header("Content-type: text/csv"); header("Content-Disposition: attachment; filename=ideary_users.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo "email,name\n"; $model = $this->getModel("Users"); $users = $model->getAllUsers(); foreach ($users as $user) { echo $user->email . ", " . ucwords(trim($user->name)) . "\r\n"; } $app->close(); } Now, this is actually working perfectly fine. The issue here is that after I download a file, if I hit any button in the admin that causes a POST, instead of it performing the action it should, it just downloads the file over again! For example: I hit the "Export" button "users.csv" downloads Then, I hit the "search" button "users.csv" downloads... what the hell? I'm guessing that when I hit the export button, a JS gets called and sets a form's action attribute to an URL... and expects a response or something, and then other button's are prevented from re-setting the form's action attribute. I can't think of any real solution for this, but I'd rather avoid hacks if possible. So, what would be the standard, elegant solution that joomla offers in this case?

  • Model Binding using ASP.NET MVC, getting datainput to the controller.

    - by Calibre2010
    Pretty Basic one here guys. I have a View which holds 2 textfields for input and a submit button <%using (Html.BeginForm("DateRetrival", "Home", FormMethod.Post)){ %> <%=Html.TextBox("sday")%> <%=Html.TextBox("eday")%> <input type="submit" value="ok" id="run"/> <% }%> the following controller action which I want to bind the data input is as follows [AcceptVerbs(HttpVerbs.Get)] public ActionResult DateRetrival() { return View(); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult DateRetrival(string submit) { return null; } When I debug this and look in the action methods parameter, the value is null. When I've entered values in both textboxes and and clicked the submit method.

  • ASP.NET MVC Custom Error Pages with Magical Unicorn

    - by FLClover
    my question is regarding Pure.Kromes answer to this post. I tried implementing my pages' custom error messages using his method, yet there are some problems I can't quite explain. a) When I provoke a 404 Error by entering in invalid URL such as localhost:3001/NonexistantPage, it defaults to the ServerError() Action of my error controller even though it should go to NotFound(). Here is my ErrorController: public class ErrorController : Controller { public ActionResult NotFound() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.NotFound; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } public ActionResult ServerError() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.InternalServerError; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } } My error routes in Global.asax.cs: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" }); routes.MapRoute( name: "Error - 404", url: "NotFound", defaults: new { controller = "Error", action = "NotFound" } ); routes.MapRoute( name: "Error - 500", url: "ServerError", defaults: new { controller = "Error", action = "ServerError" } ); And my web.config settings: <system.web> <customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="/ServerError"> <error statusCode="404" redirect="/NotFound" /> </customErrors> ... </system.web> <system.webServer> <httpErrors errorMode="Custom" existingResponse="Replace"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" path="/NotFound" responseMode="ExecuteURL" /> <remove statusCode="500" subStatusCode="-1" /> <error statusCode="500" path="/ServerError" responseMode="ExecuteURL" /> </httpErrors> ... The Error views are located in /Views/Error/ as NotFound.cshtml and ServerError.cshtml. b) One funny thing is, When a server error occurs, it does in fact display the Server Error view I defined, however it also outputs a default error message as well saying that the Error page could not be found. Here's how it looks like: Do you have any advice how I could fix these two problems? I really like Pure.Kromes approach to implementing these error messages, but if there are better ways of achieving this don't hestitate to tell me. Thanks! *EDIT : * I can directly navigate to my views through the ErrorController by accessing /Error/NotFound or Error/ServerError. The views themselves only contain some text, no markup or anything. As I said, it actually works in some way, just not the way I intended it to work. There seems to be an issue with the redirect in the web.config, but I haven't been able to figure it out.

  • Edit and Create view using EditCreate.ascx partial in ASP.NET MVC

    - by mare
    If you look at the NerdDinner example of creating and editing dinners then you see they use a partial (ViewUserControl or ASCX) DinnerForm to put the functionality of creating and editing dinners into one file because it is essential the same and they use it using RenderPartial("DinnerForm"). This approach seems fine for me but I've run into a problem where you have to add additonal route values or html properties to the Form tag. This picks up the current action and controller automatically: <% using (Html.BeginForm()) { %> However, if I use another BeginForm() overload which allows to pass in enctype or any other attribute I have to do it like this: <% using ("Create", "Section", new { modal = true }, FormMethod.Post, new { enctype = "multipart/form-data" })) and as you can see we lose the ability to automatically detect in which View we are calling RenderPartial("OurCreateEditFormPartial"). We can't have hardcoded values in there because in Edit View this postback will fail or won't postback to the right controller action. What should I do in this case?

  • Double encoded url being fully decoded in ASP.NET

    - by Brad R
    I have just come across something that is quite strange and yet I haven't found any mention on the interwebs of others having the same problem. If I hit my ASP.NET application with a double encoded url then the Request["myQueryParam"] will do a double decode of the query for me. This is not desirable as I have double encoded my query string for a good reason. Can others confirm I'm not doing something obviously wrong, and why this would happen. A solution to prevent it, without doing some nasty query string parsing, would be great too! As an example if you hit the url: http://localhost/MyApp?originalUrl=http%3a%2f%2flocalhost%2fAction%2fRedirect%3fUrl%3d%252fsomeUrl%253futm_medium%253dabc%2526utm_source%253dabc%2526utm_campaign%253dabc (For reference %25 is the % symbol) Then look at the Request["originalUrl"] (page or controller) the string returned is: http://localhost/Action/Redirect?Url=/someUrl?utm_medium=abc&utm_source=abc&utm_campaign=abc I would expect: http://localhost/Action/Redirect?Url=%2fsomeUrl%3futm_medium%3dabc%26utm_source%3dabc%26utm_campaign%3dabc I have also checked in Fiddler and the URL is being passed to the server correctly (one possible culprit could have been the browser decoding the URL before sending).

  • iPhone animation: how do I animate the filling up of an area?

    - by Sandeep
    Consider a circle. Now consider a radius of the circle, drawn from the center of the circle towards the right. Now imagine that the radius is rotating about the center of the circle, sweeping out an area as it rotates. My problem is: I want to use iPhone's animation techniques to fill up the swept out area with a different color from the background area of the circle, as the radius rotates from 0 degrees to any chosen number of degrees about the circle. I've looked through the Core Animation API, KeyFrame Animations, etc. but I am not able to find out how to do this. Any hints will be most welcome. Thanks, Sandeep

  • Can't get a LiveFolder to launch my activity like it should

    - by Felix
    I was able to create a ContentProvider for a LiveFolder, but I can't seem to be able to create my intents correctly, so it always gives "Application is not installed on your phone" errors when clicking on items inside the folder. My Activity is defined like so, in the manifest: <activity android:name=".MyActivity"> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> Then, I create the intents I place in the LiveFolders.INTENT column like this: i = new Intent(); i.setAction(null); i.setClassName("my.package.here", ".MyActivity"); I don't get why this is not working. Maybe I'm making some stupid mistake, but please point me in the right direction.
