  • Mixing secure & unsecure channels

    - by user305023
    I am unable to use an unsecure channel once a secure channel has already been registered. The code below works only if on the client side, the unsecured channel is registered before. Is it possible to mix secure and unsecure channels without any constraint on the registration order ? using System; using System.Collections; using System.Runtime.Remoting; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Tcp; public class SampleObject : MarshalByRefObject { public DateTime GetTest() { return DateTime.Now; } } public class SampleObject2 : MarshalByRefObject { public DateTime GetTest2() { return DateTime.Now; } } static class ProgramClient { private static TcpClientChannel RegisterChannel(bool secure, string name, int priority) { IDictionary properties = new Hashtable(); properties.Add("secure", secure); properties.Add("name", name); properties.Add("priority", priority); var clientChannel = new TcpClientChannel(properties, null); ChannelServices.RegisterChannel(clientChannel, false); return clientChannel; } private static void Secure() { RegisterChannel(true, "clientSecure", 2); var testSecure = (SampleObject2)Activator.GetObject(typeof(SampleObject2), "tcp://127.0.0.1:8081/Secured.rem"); Console.WriteLine("secure: " + testSecure.GetTest2().ToLongTimeString()); } private static void Unsecure() { RegisterChannel(false, "clientUnsecure", 1); var test = (SampleObject)Activator.GetObject(typeof(SampleObject), "tcp://127.0.0.1:8080/Unsecured.rem"); Console.WriteLine("unsecure: " + test.GetTest().ToLongTimeString()); } internal static void MainClient() { Console.Write("Press Enter to start."); Console.ReadLine(); // Works only in this order Unsecure(); Secure(); Console.WriteLine("Press ENTER to end"); Console.ReadLine(); } } static class ProgramServer { private static TcpServerChannel RegisterChannel(int port, bool secure, string name) { IDictionary properties = new Hashtable(); properties.Add("port", port); properties.Add("secure", secure); properties.Add("name", name); //properties.Add("impersonate", false); var serverChannel = new TcpServerChannel(properties, null); ChannelServices.RegisterChannel(serverChannel, secure); return serverChannel; } private static void StartUnsecure() { RegisterChannel(8080, false, "unsecure"); RemotingConfiguration.RegisterWellKnownServiceType(typeof(SampleObject), "Unsecured.rem", WellKnownObjectMode.Singleton); } private static void StartSecure() { RegisterChannel(8081, true, "secure"); RemotingConfiguration.RegisterWellKnownServiceType(typeof(SampleObject2), "Secured.rem", WellKnownObjectMode.Singleton); } internal static void MainServer() { StartUnsecure(); StartSecure(); Console.WriteLine("Unsecure: 8080\n Secure: 8081"); Console.WriteLine("Press the enter key to exit..."); Console.ReadLine(); } } class Program { static void Main(string[] args) { if (args.Length == 1 && args[0] == "server") ProgramServer.MainServer(); else ProgramClient.MainClient(); } }

    - by Eyla
    I have asp.net content page with an update panel, asp.net controls with ajax extenders and it has asp.net button with event click. everything is working ok exept one case. I have 3 DropDownList with CascadingDropDown extenders. when I click the button without selecting anything from DropDownLists then click on the button the event click will work OK but if I select anything my page will respond when I click on the button.

  • WCF and Firewalls

    - by Amitd
    Hi guys, As a part of learning WCF, I was trying to use a simple WCF client-server code . http://weblogs.asp.net/ralfw/archive/2007/04/14/a-truely-simple-example-to-get-started-with-wcf.aspx but I'm facing strange issues.I was trying out the following. Client(My) IP address is : 192.168.2.5 (internal behind firewall) Server IP address is : 192.168.50.30 port : 9050 (internal behind firewall) Servers LIVE/External IP (on internet ) : 121.225.xx.xx (accessible from internet) When I specify the above I.P address of server(192.168.50.30), the client connects successfully and can call servers methods. Now suppose if I want to give my friend (outside network/on internet) the client with server's live I.P, i get an ENDPOINTNOTFOUND exceptions. Surprisingly if I run the above client specifying LIVE IP(121.225.xx.xx) of server i also get the same exception. I tried to debug the problem but haven't found anything. Is it a problem with the company firewall not forwarding my request? or is it a problem with the server or client . Is something needed to be added to the server/client to overcome the same problem? Or are there any settings on the firewall that need to be changed like port forwarding? (our network admin has configured the port to be accessible from the internet.) is it a authentication issue? Code is available at . http://www.ralfw.de/weblog/wcfsimple.txt http://weblogs.asp.net/ralfw/archive/2007/04/14/a-truely-simple-example-to-get-started-with-wcf.aspx i have just separated the client and server part in separate assemblies.rest is same. using System; using System.Collections.Generic; using System.Text; using System.ServiceModel; namespace WCFSimple.Contract { [ServiceContract] public interface IService { [OperationContract] string Ping(string name); } } namespace WCFSimple.Server { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] class ServiceImplementation : WCFSimple.Contract.IService { #region IService Members public string Ping(string name) { Console.WriteLine("SERVER - Processing Ping('{0}')", name); return "Hello, " + name; } #endregion } public class Program { private static System.Threading.AutoResetEvent stopFlag = new System.Threading.AutoResetEvent(false); public static void Main() { ServiceHost svh = new ServiceHost(typeof(ServiceImplementation)); svh.AddServiceEndpoint( typeof(WCFSimple.Contract.IService), new NetTcpBinding(), "net.tcp://localhost:8000"); svh.Open(); Console.WriteLine("SERVER - Running..."); stopFlag.WaitOne(); Console.WriteLine("SERVER - Shutting down..."); svh.Close(); Console.WriteLine("SERVER - Shut down!"); } public static void Stop() { stopFlag.Set(); } } } namespace WCFSimple { class Program { static void Main(string[] args) { Console.WriteLine("WCF Simple Demo"); // start server System.Threading.Thread thServer = new System.Threading.Thread(WCFSimple.Server.Program.Main); thServer.IsBackground = true; thServer.Start(); System.Threading.Thread.Sleep(1000); // wait for server to start up // run client ChannelFactory<WCFSimple.Contract.IService> scf; scf = new ChannelFactory<WCFSimple.Contract.IService>( new NetTcpBinding(), "net.tcp://localhost:8000"); WCFSimple.Contract.IService s; s = scf.CreateChannel(); while (true) { Console.Write("CLIENT - Name: "); string name = Console.ReadLine(); if (name == "") break; string response = s.Ping(name); Console.WriteLine("CLIENT - Response from service: " + response); } (s as ICommunicationObject).Close(); // shutdown server WCFSimple.Server.Program.Stop(); thServer.Join(); } } } Any help?

  • MODI leaking memory

    - by Khragg
    I have an app where I'm using MODI 2007 to OCR several multi-page tiff files. I have found that when I kick it off on a directory that contains several good tiffs but also some tiffs that cannot be opened in Windows Picture and Fax Viewer, then MODI also fails to OCR those "bad" tiffs. When this happens, the app is unable to reclaim any of the memory that was used by MODI to OCR those tiffs. After the tool tries to OCR too many of these "bad" tiffs, the machine runs out of memory and the app crashes. I have tried several code fixes from the web that supposedly fix any MODI memory leaks, but so far none have worked for me. I am pasting in the part of the code below that does the OCRing: StringBuilder strRecText = new StringBuilder(10000); MODI.Document doc1 = new MODI.Document(); doc1.Create(name); try { doc1.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true); // this will ocr all pages of a multi-page tiff file } catch (Exception e) { doc1.Close(false); // clean up if (doc1 != null) { GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } } MODI.Images images = doc1.Images; for (int imageCounter = 0; imageCounter < images.Count; imageCounter++) { if (imageCounter > 0) { if (!noPageBreakFlag) { strRecText.Append((char)pageBreakChar); } } MODI.Image image = (MODI.Image)images[imageCounter]; MODI.Layout layout = image.Layout; strRecText.Append(layout.Text); GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (layout != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(layout); layout = null; } if (image != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(image); image = null; } } File.AppendAllText(ocrFile, strRecText.ToString()); // write the OCR file out to disk GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (images != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(images); images = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); doc1.Close(false); // clean up if (doc1 != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers();

  • How Do I Bind a "selected Item" in a Listbox to a ItemsControl in WPF?

    - by Scott
    LowDown: I am trying to create a Document Viewer in WPF. It will allow the user to preview selected documents and if they want, compare the documents in WPF. So they can view them side by side. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

  • claimsResponse Always Return Null

    - by Chirag Pandya
    hello i have a following code in asp.net. i have used DotNetOpenAuth.dll for openID. the code is under protected void openidValidator_ServerValidate(object source, ServerValidateEventArgs args) { // This catches common typos that result in an invalid OpenID Identifier. args.IsValid = Identifier.IsValid(args.Value); } protected void loginButton_Click(object sender, EventArgs e) { if (!this.Page.IsValid) { return; // don't login if custom validation failed. } try { using (OpenIdRelyingParty openid = this.createRelyingParty()) { IAuthenticationRequest request = openid.CreateRequest(this.openIdBox.Text); // This is where you would add any OpenID extensions you wanted // to include in the authentication request.

  • Problem with URL encoded parameters in URL view helper

    - by Richard Knop
    So my problem is kinda weird, it only occurs when I test the application offline (on my PC with WampServer), the same code works 100% correctly online. Here is how I use the helper (just example): <a href="<?php echo $this->url(array('module' => 'admin', 'controller' => 'index', 'action' => 'approve-photo', 'id' => $this->escape($a->id), 'ret' => urlencode('admin/index/photos')), null, true); ?>" class="blue">approve</a> Online, this link works great, it goes to the action which looks similar to this: public function approvePhotoAction() { $request = $this->getRequest(); $photos = $this->_getTable('Photos'); $dbTrans = false; try { $db = $this->_getDb(); $dbTrans = $db->beginTransaction(); $photos->edit($request->getParam('id'), array('status' => 'approved')); $db->commit(); } catch (Exception $e) { if (true === $dbTrans) { $db->rollBack(); } } $this->_redirect(urldecode($request->getParam('ret'))); } So online, it approves the photo and redirects back to the URL that is encoded as "ret" param in the URL ("admin/index/photos"). But offline with WampServer I click on the link and get 404 error like this: Not Found The requested URL /public/admin/index/approve-photo/id/1/ret/admin/index/photos was not found on this server. What the hell? I'm using the latest version of WampServer (WampServer 2.0i [11/07/09]). Everything else works. Here is my .htaccess file, just in case: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ /index.php [NC,L] # Turn off magic quotes #php_flag magic_quotes_gpc off I'm using virtual hosts to test ZF projects on my local PC. Here is how I add virtual hosts. httpd.conf: NameVirtualHost *:80 <VirtualHost *:80> ServerName myproject DocumentRoot "C:\wamp\www\myproject" </VirtualHost> the hosts file: 127.0.0.1 myproject Any help would be appreciated because this makes testing and debugging projects on my localhost a nightmare and almost impossible task. I have to upload everything online to check if it works :( UPDATE: Source code of the _redirect helper (built in ZF helper): /** * Set redirect in response object * * @return void */ protected function _redirect($url) { if ($this->getUseAbsoluteUri() && !preg_match('#^(https?|ftp)://#', $url)) { $host = (isset($_SERVER['HTTP_HOST'])?$_SERVER['HTTP_HOST']:''); $proto = (isset($_SERVER['HTTPS'])&&$_SERVER['HTTPS']!=="off") ? 'https' : 'http'; $port = (isset($_SERVER['SERVER_PORT'])?$_SERVER['SERVER_PORT']:80); $uri = $proto . '://' . $host; if ((('http' == $proto) && (80 != $port)) || (('https' == $proto) && (443 != $port))) { $uri .= ':' . $port; } $url = $uri . '/' . ltrim($url, '/'); } $this->_redirectUrl = $url; $this->getResponse()->setRedirect($url, $this->getCode()); } UPDATE 2: Output of the helper offline: /admin/index/approve-photo/id/1/ret/admin%252Findex%252Fphotos And online (the same): /admin/index/approve-photo/id/1/ret/admin%252Findex%252Fphotos UPDATE 3: OK. The problem was actually with the virtual host configuration. The document root was set to C:\wamp\www\myproject instead of C:\wamp\www\myproject\public. And I was using this htaccess to redirect to the public folder: RewriteEngine On php_value upload_max_filesize 15M php_value post_max_size 15M php_value max_execution_time 200 php_value max_input_time 200 # Exclude some directories from URI rewriting #RewriteRule ^(dir1|dir2|dir3) - [L] RewriteRule ^\.htaccess$ - [F] RewriteCond %{REQUEST_URI} ="" RewriteRule ^.*$ /public/index.php [NC,L] RewriteCond %{REQUEST_URI} !^/public/.*$ RewriteRule ^(.*)$ /public/$1 RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^.*$ - [NC,L] RewriteRule ^public/.*$ /public/index.php [NC,L] Damn it I don't know why I forgot about this, I thought the virtual host was configured correctly to the public folder, I was 100% sure about that, I also double checked it and saw no problem (wtf? am I blind?).

(Only the first button's actionListener is here, the others' are practically the same). The panel is in a JFrame with two other panels that yet do nothing. How could I make it work properly?

Here is my Site.Master <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Elite.WUI.Site" %> <!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 runat="server"> <title></title> <link rel="stylesheet" type="text/css" href="styles.css" /> </head> <body> <form id="form1" runat="server"> <asp:ContentPlaceHolder ID="headerCPH" runat="server"> <div id="header"> <h1>WUI</h1> </div> <hr /> </asp:ContentPlaceHolder> <asp:ContentPlaceHolder ID="navigationCPH" runat="server"> <div id="navigation"> <ul> <li>Home</li> <li>Users</li> <li>Campaigns</li> <li>Settings</li> </ul> </div> </asp:ContentPlaceHolder> <asp:ContentPlaceHolder ID="contentCPH" runat="server"> </asp:ContentPlaceHolder> </form> </body> </html> my stylesheet styles.css #navigation { float: left; border: 1pt solid; } #navigation ul { list-style-type: none; padding: 5 5 5 5; margin: 0; } #content { margin-left: 9%; border: 1pt solid; padding-left: 5; } and the actual page derived from master page <%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="ABC.aspx.cs" Inherits="Elite.WUI.ABC" %> <asp:Content ID="Content3" ContentPlaceHolderID="contentCPH" runat="server"> <div id="content"> <p>Test content</p> </div> </asp:Content> Here is how it is displayed in Firefox (ver 3.6) As you can see that the border, list-style-type properties are working but margin isn't working. Can anyone tell me what am I doing wrong? I have tested it in Google Chrome but same issue. While the HTML and CSS works fine when there is no ASP.NET i.e. simple .html file.

  • Fluent NHibernate - subclasses with shared reference

    - by ollie
    Edit: changed class names. I'm using Fluent NHibernate (v 1.0.0.614) automapping on the following set of classes (where Entity is the base class provided in the S#arp Architecture framework): public class Car : Entity { public virtual int ModelYear { get; set; } public virtual Company Manufacturer { get; set; } } public class Sedan : Car { public virtual bool WonSedanOfYear { get; set; } } public class Company : Entity { public virtual IList<Sedan> Sedans { get; set; } } This results in the following Configuration (as written to hbm.xml): <class name="Company" table="Companies"> <id name="Id" type="System.Int32" unsaved-value="0"> <column name="`ID`" /> <generator class="identity" /> </id> <bag cascade="all" inverse="true" name="Sedans" mutable="true"> <key> <column name="`CompanyID`" /> </key> <one-to-many class="Sedan" /> </bag> </class> <class name="Car" table="Cars"> <id name="Id" type="System.Int32" unsaved-value="0"> <column name="`ID`" /> <generator class="identity" /> </id> <property name="ModelYear" type="System.Int32"> <column name="`ModelYear`" /> </property> <many-to-one cascade="save-update" class="Company" name="Manufacturer"> <column name="`CompanyID`" /> </many-to-one> <joined-subclass name="Sedan"> <key> <column name="`CarID`" /> </key> <property name="WonSedanOfYear" type="System.Boolean"> <column name="`WonSedanOfYear`" /> </property> </joined-subclass> </class> So far so good! But now comes the ugly part. The generated database tables: Table: Companies Columns: ID (PK, int, not null) Table: Cars Columns: ID (PK, int, not null) ModelYear (int, null) CompanyID (FK, int, null) Table: Sedan Columns: CarID (PK, FK, int, not null) WonSedanOfYear (bit, null) CompanyID (FK, int, null) Instead of one FK for Company, I get two! How can I ensure I only get one FK for Company? Override the automapping? Put a convention in place? Or is this a bug? Your thoughts are appreciated.

  • How to save a large nhibernate collection without causing OutOfMemoryException

    - by Michael Hedgpeth
    How do I save a large collection with NHibernate which has elements that surpass the amount of memory allowed for the process? I am trying to save a Video object with nhibernate which has a large number of Screenshots (see below for code). Each Screenshot contains a byte[], so after nhibernate tries to save 10,000 or so records at once, an OutOfMemoryException is thrown. Normally I would try to break up the save and flush the session after every 500 or so records, but in this case, I need to save the collection because it automatically saves the SortOrder and VideoId for me (without the Screenshot having to know that it was a part of a Video). What is the best approach given my situation? Is there a way to break up this save without forcing the Screenshot to have knowledge of its parent Video? For your reference, here is the code from the simple sample I created: public class Video { public long Id { get; set; } public string Name { get; set; } public Video() { Screenshots = new ArrayList(); } public IList Screenshots { get; set; } } public class Screenshot { public long Id { get; set; } public byte[] Data { get; set; } } And mappings: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="SavingScreenshotsTrial" namespace="SavingScreenshotsTrial" default-access="property"> <class name="Screenshot" lazy="false"> <id name="Id" type="Int64"> <generator class="hilo"/> </id> <property name="Data" column="Data" type="BinaryBlob" length="2147483647" not-null="true" /> </class> </hibernate-mapping> <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="SavingScreenshotsTrial" namespace="SavingScreenshotsTrial" > <class name="Video" lazy="false" table="Video" discriminator-value="0" abstract="true"> <id name="Id" type="Int64" access="property"> <generator class="hilo"/> </id> <property name="Name" /> <list name="Screenshots" cascade="all-delete-orphan" lazy="false"> <key column="VideoId" /> <index column="SortOrder" /> <one-to-many class="Screenshot" /> </list> </class> </hibernate-mapping> When I try to save a Video with 10000 screenshots, it throws an OutOfMemoryException. Here is the code I'm using: using (var session = CreateSession()) { Video video = new Video(); for (int i = 0; i < 10000; i++) { video.Screenshots.Add(new Screenshot() {Data = camera.TakeScreenshot(resolution)}); } session.SaveOrUpdate(video); }

  • Single DispatcherServlet with Multiple Controllers

    - by jwmajors81
    I am trying to create some restful web services using Spring MVC 3.0. I currently have an issue that only 1 of my 2 controllers will work at any given time. As it turns out, whichever class comes first when sorted alphabetically will work properly. The error I get is: handleNoSuchRequestHandlingMethod No matching handler method found for servlet request: path '/polinq.xml', method 'GET', parameters map[[empty]] I had a very simliar message earlier also, except instead of the map being empty it was something like map[v--String(array)] Regardless of the message though, currently the LocationCovgController works and the PolicyInquiryController doesn't. If I change the change of the PolicyInquiryController to APolicyInquiryController, then it will start funcitoning properly and the LocationCovgController will stop working. Any assistance would be greatly appreciated. Thank you very much, Jeremy The information provided below includes the skeleton of both controller classes and also the servlet config file that defines how spring should be setup. Controller 1 package org.example; @Controller @RequestMapping(value = "/polinq.*") public class PolicyInquiryController { @RequestMapping(value = "/polinq.*?comClientId={comClientId}") public ModelAndView getAccountSummary( @PathVariable("comClientId") String commercialClientId) { // setup of variable as was removed. ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "accsumm", as); return mav; } } Controller 2 package org.example; @Controller @RequestMapping(value = "/loccovginquiry.*") public class LocationCovgController { @RequestMapping(value = "/loccovginquiry.*method={method}") public ModelAndView locationCovgInquiryByPolicyNo( @PathVariable("method")String method) { ModelAndView mav = new ModelAndView("XmlView", BindingResult.MODEL_KEY_PREFIX + "loccovg", covgs); return mav; } } Servlet Config <context:component-scan base-package="org.example." /> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver" p:order="0"> <property name="mediaTypes"> <map> <entry key="atom" value="application/atom+xml"/> <entry key="xml" value="application/xml"/> <entry key="json" value="application/json"/> <entry key="html" value="text/html"/> </map> </property> <property name="defaultContentType" value="text/html"/> <property name="ignoreAcceptHeader" value="true"/> <property name="favorPathExtension" value="true"/> <property name="viewResolvers"> <list> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </list> </property> <property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/> </list> </property> </bean> <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> <bean id="XmlView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <property name="marshaller" ref="marshaller"/> </bean> <oxm:jaxb2-marshaller id="marshaller"> <oxm:class-to-be-bound name="org.example.policy.dto.AccountSummary"/> <oxm:class-to-be-bound name="org.example.policy.dto.InsuredName"/> <oxm:class-to-be-bound name="org.example.policy.dto.Producer"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverage"/> <oxm:class-to-be-bound name="org.example.policy.dto.PropertyLocCoverages"/> </oxm:jaxb2-marshaller>

  • Wordpress add_meta_box() weirdness

    The code below is working nearly flawlessly, however my value for page title on one of my pages keeps coming up empty after a few page refreshes...

  • My Dijit DateTimeCombo widget doesn't send selected value on form submission

    - by david bessire
    i need to create a Dojo widget that lets users specify date & time. i found a sample implementation attached to an entry in the Dojo bug tracker. It looks nice and mostly works, but when i submit the form, the value sent by the client is not the user-selected value but the value sent from the server. What changes do i need to make to get the widget to submit the date & time value? Sample usage is to render a JSP with basic HTML tags (form & input), then dojo.addOnLoad a function which selects the basic elements by ID, adds dojoType attribute, and dojo.parser.parse()-es the page. Thanks in advance. The widget is implemented in two files. The application uses Dojo 1.3. File 1: DateTimeCombo.js dojo.provide("dojox.form.DateTimeCombo"); dojo.require("dojox.form._DateTimeCombo"); dojo.require("dijit.form._DateTimeTextBox"); dojo.declare( "dojox.form.DateTimeCombo", dijit.form._DateTimeTextBox, { baseClass: "dojoxformDateTimeCombo dijitTextBox", popupClass: "dojox.form._DateTimeCombo", pickerPostOpen: "pickerPostOpen_fn", _selector: 'date', constructor: function (argv) {}, postMixInProperties: function() { dojo.mixin(this.constraints, { /* datePattern: 'MM/dd/yyyy HH:mm:ss', timePattern: 'HH:mm:ss', */ datePattern: 'MM/dd/yyyy HH:mm', timePattern: 'HH:mm', clickableIncrement:'T00:15:00', visibleIncrement:'T00:15:00', visibleRange:'T01:00:00' }); this.inherited(arguments); }, _open: function () { this.inherited(arguments); if (this._picker!==null && (this.pickerPostOpen!==null && this.pickerPostOpen!=="")) { if (this._picker.pickerPostOpen_fn!==null) { this._picker.pickerPostOpen_fn(this); } } } } ); File 2: _DateTimeCombo.js dojo.provide("dojox.form._DateTimeCombo"); dojo.require("dojo.date.stamp"); dojo.require("dijit._Widget"); dojo.require("dijit._Templated"); dojo.require("dijit._Calendar"); dojo.require("dijit.form.TimeTextBox"); dojo.require("dijit.form.Button"); dojo.declare("dojox.form._DateTimeCombo", [dijit._Widget, dijit._Templated], { // invoked only if time picker is empty defaultTime: function () { var res= new Date(); res.setHours(0,0,0); return res; }, // id of this table below is the same as this.id templateString: " <table class=\"dojoxDateTimeCombo\" waiRole=\"presentation\">\ <tr class=\"dojoxTDComboCalendarContainer\">\ <td>\ <center><input dojoAttachPoint=\"calendar\" dojoType=\"dijit._Calendar\"></input></center>\ </td>\ </tr>\ <tr class=\"dojoxTDComboTimeTextBoxContainer\">\ <td>\ <center><input dojoAttachPoint=\"timePicker\" dojoType=\"dijit.form.TimeTextBox\"></input></center>\ </td>\ </tr>\ <tr><td><center><button dojoAttachPoint=\"ctButton\" dojoType=\"dijit.form.Button\">Ok</button></center></td></tr>\ </table>\ ", widgetsInTemplate: true, constructor: function(arg) {}, postMixInProperties: function() { this.inherited(arguments); }, postCreate: function() { this.inherited(arguments); this.connect(this.ctButton, "onClick", "_onValueSelected"); }, // initialize pickers to calendar value pickerPostOpen_fn: function (parent_inst) { var parent_value = parent_inst.attr('value'); if (parent_value !== null) { this.setValue(parent_value); } }, // expects a valid date object setValue: function(value) { if (value!==null) { this.calendar.attr('value', value); this.timePicker.attr('value', value); } }, // return a Date constructed date in calendar & time in time picker. getValue: function() { var value = this.calendar.attr('value'); var result=value; if (this.timePicker.value !== null) { if ((this.timePicker.value instanceof Date) === true) { result.setHours(this.timePicker.value.getHours(), this.timePicker.value.getMinutes(), this.timePicker.value.getSeconds()); return result; } } else { var defTime=this.defaultTime(); result.setHours(defTime.getHours(), defTime.getMinutes(), defTime.getSeconds()); return result; } }, _onValueSelected: function() { var value = this.getValue(); this.onValueSelected(value); }, onValueSelected: function(value) {} });

  • How can I properly implement inetcpl.cpl as an external dll?

    - by Kyt
    I have the following 2 sets of code, both of which produce the same results: using System.Linq; using System.Runtime.InteropServices; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace ResetIE { class Program { [DllImport("InetCpl.cpl", SetLastError=true, CharSet=CharSet.Unicode, EntryPoint="ClearMyTracksByProcessW")] public static extern long ClearMyTracksByProcess(IntPtr hwnd, IntPtr hinst, ref TargetHistory lpszCmdLine, FormWindowState nCmdShow); static void Main(string[] args) { TargetHistory th = TargetHistory.CLEAR_TEMPORARY_INTERNET_FILES; ClearMyTracksByProcessW(Process.GetCurrentProcess().Handle, Marshal.GetHINSTANCE(typeof(Program).Module), ref th, FormWindowState.Maximized); Console.WriteLine("Done."); } } and ... static class NativeMethods { [DllImport("kernel32.dll")] public static extern IntPtr LoadLibrary(string dllToLoad); [DllImport("kernel32.dll")] public static extern IntPtr GetProcAddress(IntPtr hModule, string procedureName); [DllImport("kernel32.dll")] public static extern bool FreeLibrary(IntPtr hModule); } public class CallExternalDLL { [UnmanagedFunctionPointer(CallingConvention.Cdecl)] public delegate long ClearMyTracksByProcessW(IntPtr hwnd, IntPtr hinst, ref TargetHistory lpszCmdLine, FormWindowState nCmdShow); public static void Clear_IE_Cache() { IntPtr pDll = NativeMethods.LoadLibrary(@"C:\Windows\System32\inetcpl.cpl"); if (pDll == IntPtr.Zero) { Console.WriteLine("An Error has Occurred."); } IntPtr pAddressOfFunctionToCall = NativeMethods.GetProcAddress(pDll, "ClearMyTracksByProcessW"); if (pAddressOfFunctionToCall == IntPtr.Zero) { Console.WriteLine("Function Not Found."); } ClearMyTracksByProcessW cmtbp = (ClearMyTracksByProcessW)Marshal.GetDelegateForFunctionPointer(pAddressOfFunctionToCall, typeof(ClearMyTracksByProcessW)); TargetHistory q = TargetHistory.CLEAR_TEMPORARY_INTERNET_FILES; long result = cmtbp(Process.GetCurrentProcess().Handle, Marshal.GetHINSTANCE(typeof(ClearMyTracksByProcessW).Module), ref q, FormWindowState.Normal); } } both use the following Enum: public enum TargetHistory { CLEAR_ALL = 0xFF, CLEAR_ALL_WITH_ADDONS = 0x10FF, CLEAR_HISTORY = 0x1, CLEAR_COOKIES = 0x2, CLEAR_TEMPORARY_INTERNET_FILES = 0x8, CLEAR_FORM_DATA = 0x10, CLEAR_PASSWORDS = 0x20 } Both methods of doing this compile and run just fine, offering no errors, but both churn endlessly never returning from their work. The PInvoke code was ported from the following VB, which was fairly difficult to track down: Option Explicit Private Enum TargetHistory CLEAR_ALL = &HFF& CLEAR_ALL_WITH_ADDONS = &H10FF& CLEAR_HISTORY = &H1& CLEAR_COOKIES = &H2& CLEAR_TEMPORARY_INTERNET_FILES = &H8& CLEAR_FORM_DATA = &H10& CLEAR_PASSWORDS = &H20& End Enum Private Declare Function ClearMyTracksByProcessW Lib "InetCpl.cpl" _ (ByVal hwnd As OLE_HANDLE, _ ByVal hinst As OLE_HANDLE, _ ByRef lpszCmdLine As Byte, _ ByVal nCmdShow As VbAppWinStyle) As Long Private Sub Command1_Click() Dim b() As Byte Dim o As OptionButton For Each o In Option1 If o.Value Then b = o.Tag ClearMyTracksByProcessW Me.hwnd, App.hInstance, b(0), vbNormalFocus Exit For End If Next End Sub Private Sub Form_Load() Command1.Caption = "??" Option1(0).Caption = "?????????????" Option1(0).Tag = CStr(CLEAR_TEMPORARY_INTERNET_FILES) Option1(1).Caption = "Cookie" Option1(1).Tag = CStr(CLEAR_COOKIES) Option1(2).Caption = "??" Option1(2).Tag = CStr(CLEAR_HISTORY) Option1(3).Caption = "???? ???" Option1(3).Tag = CStr(CLEAR_HISTORY) Option1(4).Caption = "?????" Option1(4).Tag = CStr(CLEAR_PASSWORDS) Option1(5).Caption = "?????" Option1(5).Tag = CStr(CLEAR_ALL) Option1(2).Value = True End Sub The question is simply what am I doing wrong? I need to clear the internet cache, and would prefer to use this method as I know it does what I want it to when it works (rundll32 inetcpl.cpl,ClearMyTracksByProcess 8 works fine). I've tried running both as normal user and admin to no avail. This project is written using C# in VS2012 and compiled against .NET3.5 (must remain at 3.5 due to client restrictions)

  • Custom links in RichTextBox

    - by IVlad
    Suppose I want every word starting with a # to generate an event on double click. For this I have implemented the following test code: private bool IsChannel(Point position, out int start, out int end) { if (richTextBox1.Text.Length == 0) { start = end = -1; return false; } int index = richTextBox1.GetCharIndexFromPosition(position); int stop = index; while (index >= 0 && richTextBox1.Text[index] != '#') { if (richTextBox1.Text[index] == ' ') { break; } --index; } if (index < 0 || richTextBox1.Text[index] != '#') { start = end = -1; return false; } while (stop < richTextBox1.Text.Length && richTextBox1.Text[stop] != ' ') { ++stop; } --stop; start = index; end = stop; return true; } private void richTextBox1_MouseMove(object sender, MouseEventArgs e) { textBox1.Text = richTextBox1.GetCharIndexFromPosition(new Point(e.X, e.Y)).ToString(); int d1, d2; if (IsChannel(new Point(e.X, e.Y), out d1, out d2) == true) { if (richTextBox1.Cursor != Cursors.Hand) { richTextBox1.Cursor = Cursors.Hand; } } else { richTextBox1.Cursor = Cursors.Arrow; } } This handles detecting words that start with # and making the mouse cursor a hand when it hovers over them. However, I have the following two problems: If I try to implement a double click event for richTextBox1, I can detect when a word is clicked, however that word is highlighted (selected), which I'd like to avoid. I can deselect it programmatically by selecting the end of the text, but that causes a flicker, which I would like to avoid. What ways are there to do this? The GetCharIndexFromPosition method returns the index of the character that is closest to the cursor. This means that if the only thing my RichTextBox contains is a word starting with a # then the cursor will be a hand no matter where on the rich text control it is. How can I make it so that it is only a hand when it hovers over an actual word or character that is part of a word I'm interested in? The implemented URL detection also partially suffers from this problem. If I enable detection of URLs and only write www.test.com in the rich text editor, the cursor will be a hand as long as it is on or below the link. It will not be a hand if it's to the right of the link however. I'm fine even with this functionality if making the cursor a hand if and only if it's on the text proves to be too difficult. I'm guessing I'll have to resort to some sort of Windows API calls, but I don't really know where to start. I am using Visual Studio 2008 and I would like to implement this myself. Update: The flickering problem would be solved if I could make it so that no text is selectable through double clicking, only through dragging the mouse cursor. Is this easier to achieve? Because I don't really care if one can select text or not by double clicking in this case.

  • Unit Testing Refcounted Critical Section Class

    - by BillyONeal
    Hello all :) I'm looking at a simple class I have to manage critical sections and locks, and I'd like to cover this with test cases. Does this make sense, and how would one go about doing it? It's difficult because the only way to verify the class works is to setup very complicated threading scenarios, and even then there's not a good way to test for a leak of a Critical Section in Win32. Is there a more direct way to make sure it's working correctly? Here's the code: CriticalSection.hpp: #pragma once #include <windows.h> namespace WindowsAPI { namespace Threading { class CriticalSection; class CriticalLock { std::size_t *instanceCount; CRITICAL_SECTION * criticalStructure; bool lockValid; friend class CriticalSection; CriticalLock(std::size_t *, CRITICAL_SECTION *, bool); public: bool IsValid() { return lockValid; }; void Unlock(); ~CriticalLock() { Unlock(); }; }; class CriticalSection { std::size_t *instanceCount; CRITICAL_SECTION * criticalStructure; public: CriticalSection(); CriticalSection(const CriticalSection&); CriticalSection& operator=(const CriticalSection&); CriticalSection& swap(CriticalSection&); ~CriticalSection(); CriticalLock Enter(); CriticalLock TryEnter(); }; }} CriticalSection.cpp: #include "CriticalSection.hpp" namespace WindowsAPI { namespace Threading { CriticalSection::CriticalSection() { criticalStructure = new CRITICAL_SECTION; instanceCount = new std::size_t; *instanceCount = 1; InitializeCriticalSection(criticalStructure); } CriticalSection::CriticalSection(const CriticalSection& other) { criticalStructure = other.criticalStructure; instanceCount = other.instanceCount; instanceCount++; } CriticalSection& CriticalSection::operator=(const CriticalSection& other) { CriticalSection copyOfOther(other); swap(copyOfOther); return *this; } CriticalSection& CriticalSection::swap(CriticalSection& other) { std::swap(other.instanceCount, instanceCount); std::swap(other.criticalStructure, other.criticalStructure); return *this; } CriticalSection::~CriticalSection() { if (!--(*instanceCount)) { DeleteCriticalSection(criticalStructure); delete criticalStructure; delete instanceCount; } } CriticalLock CriticalSection::Enter() { EnterCriticalSection(criticalStructure); (*instanceCount)++; return CriticalLock(instanceCount, criticalStructure, true); } CriticalLock CriticalSection::TryEnter() { bool lockAquired; if (TryEnterCriticalSection(criticalStructure)) { (*instanceCount)++; lockAquired = true; } else lockAquired = false; return CriticalLock(instanceCount, criticalStructure, lockAquired); } void CriticalLock::Unlock() { if (!lockValid) return; LeaveCriticalSection(criticalStructure); lockValid = false; if (!--(*instanceCount)) { DeleteCriticalSection(criticalStructure); delete criticalStructure; delete instanceCount; } } }}

  • using xml type attribute for derived complex types

    - by David Michel
    Hi All, I'm trying to get derived complex types from a base type in an xsd schema. it works well when I do this (inspired by this): xml file: <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> xsd file: <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> However, if I want to have the person element inside, for example, a sequence of another complex type, it doesn't work anymore: xml: <staffRecord> <company>mycompany</company> <dpt>sales</dpt> <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Employee"> <name>John</name> <height>59</height> <jobDescription>manager</jobDescription> </person> </staffRecord> xsd file: <xs:element name="staffRecord"> <xs:complexType> <xs:sequence> <xs:element name="company" type="xs:string"/> <xs:element name="dpt" type="xs:string"/> <xs:element name="person" type="Person"/> <xs:complexType name="Person" abstract="true"> <xs:sequence> <xs:element name= "name" type="xs:string"/> <xs:element name= "height" type="xs:double" /> </xs:sequence> </xs:complexType> <xs:complexType name="Employee"> <xs:complexContent> <xs:extension base="Person"> <xs:sequence> <xs:element name="jobDescription" type="xs:string" /> </xs:sequence> </xs:extension> </xs:complexContent> </xs:complexType> </xs:sequence> </xs:complexType> </xs:element> When validating the xml with that schema with xmllint (under linux), I get this error message then: config.xsd:12: element complexType: Schemas parser error : Element '{http://www.w3.org/2001/XMLSchema}sequence': The content is not valid. Expected is (annotation?, (element | group | choice | sequence | any)*). WXS schema config.xsd failed to compile Any idea what is wrong ? David
