    - by James123
    I am trying to show my colleagues in my custom webpart. So I adding presence Icon to each of colleague. It is showing fine when colleague is 1 only. If We have colleague more than 1 Presence Icon showing for 1st colleague you can dropdow that Icon also but other colleagues it is show simple Presense Icon (grayout) (not drop down is comming). code is like this. private static Panel GetUserInfo(UserProfile profile,Panel html, int cnt) { LiteralControl imnrc = new LiteralControl(); imnrc.Text = "<span style=\"padding: 0 5px 0 5px;\"><img border=\"0\" valign=\"middle\" height=\"12\" width=\"12\" src=\"/_layouts/images/imnhdr.gif\" onload=\"IMNRC('" + profile[PropertyConstants.WorkEmail].Value.ToString() + "')\" ShowOfflinePawn=1 id=\"IMID[GUID]\" ></span>"; html.Controls.Add(imnrc); html.Controls.Add(GetNameControl(profile)); //html.Controls.Add(new LiteralControl("<br>")); return html; } private static Control GetNameControl(UserProfile profile) { //bool hasMySite = profile[PropertyConstants.PublicSiteRedirect].Value == null ? false : true; bool hasMySite =string.IsNullOrEmpty(profile.PublicUrl.ToString()) ? false : true; string name = profile[PropertyConstants.PreferredName].Value.ToString(); if (hasMySite) { HyperLink control = new HyperLink(); control.NavigateUrl = String.IsNullOrEmpty(profile.PublicUrl.ToString()) ? null : profile.PublicUrl.ToString(); control.Style.Add("text-decoration","none"); control.Text = name; return control; } else { LiteralControl control = new LiteralControl(); control.Text = name; return control; } } http://i700.photobucket.com/albums/ww5/vsrikanth/presence-1.jpg

  • Swing - how to mix JTextField and JTextAreas and have same visual appearance?

    - by I82Much
    I am using miglayout to create a form in which there are JTextFields (short input answers) as well as JTextAreas (Longer answers). The problem is twofold. The border placed around a Scrollpane wrapped text area does not match that of a Text Field. The width and placement of the textarea/textfield differ, causing them not to line up correctly. Source code: package test2; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JTextField; import net.miginfocom.swing.MigLayout; public class Test extends JPanel { private static final int NUM_CHARACTERS_WIDTH = 20; private static final int NUM_ROWS = 5; public Test() { setLayout(new MigLayout( "wrap 2", // Align text labels on the so their right edge meets left edge of the text fields "[right][left]" )); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); add(new JLabel("No scrollpane text area:")); add(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH)); add(new JLabel("Scrollpane text area:")); add(new JScrollPane(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH))); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); } public static void main(String[] args) { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new Test(); frame.add(panel); frame.pack(); frame.setVisible(true); } } What's the preferred way to mix and match jtextfield and jtextareas, while still maintaining visual harmony? I notice now that the text field has a blue highlight around it when focus is in it, as opposed to the text area... another source of visual discontinuity.

  • Javascript scope chain

    - by Geromey
    Hi, I am trying to optimize my program. I think I understand the basics of closure. I am confused about the scope chain though. I know that in general you want a low scope (to access variables quickly). Say I have the following object: var my_object = (function(){ //private variables var a_private = 0; return{ //public //public variables a_public : 1, //public methods some_public : function(){ debugger; alert(this.a_public); alert(a_private); }; }; })(); My understanding is that if I am in the some_public method I can access the private variables faster than the public ones. Is this correct? My confusion comes with the scope level of this. When the code is stopped at debugger, firebug shows the public variable inside the this keyword. The this word is not inside a scope level. How fast is accessing this? Right now I am storing any this.properties as another local variable to avoid accessing it multiple times. Thanks very much!

  • @Autowire strange problem

    - by Javi
    Hello, I have a strange behaviour when autowiring I have a similar code like this one, and it works @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2{ ... } The problem is that I need that the Class2 implements an interface so I've only changed the Class2 so it's now like: @Controller public class Class1 { @Autowired private Class2 object2; ... } @Service @Transactional public class Class2 implements IServiceReference<Class3, Long>{ ... } public interface IServiceReference<T, PK extends Serializable> { public T reference(PK id); } with this code I get a org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type for Class2. It seems that @ Transitional annotation is not compatible with the interface because if I remove the @Transitional annotation or the "implements IServiceReference" the problem disapears and the bean is injected (though I need to have both in this class). It also happens if I put the annotation @Transitional in the methods instead of in the Class. I use Spring 3.0.2 if this helps. Is not compatible the interface with the transactional method? May it be a Spring bug? Thanks

  • Is an "infinite" iterator bad design?

    - by Adamski
    Is it generally considered bad practice to provide Iterator implementations that are "infinite"; i.e. where calls to hasNext() always(*) return true? Typically I'd say "yes" because the calling code could behave erratically, but in the below implementation hasNext() will return true unless the caller removes all elements from the List that the iterator was initialised with; i.e. there is a termination condition. Do you think this is a legitimate use of Iterator? It doesn't seem to violate the contract although I suppose one could argue it's unintuitive. public class CyclicIterator<T> implements Iterator<T> { private final List<T> l; private Iterator it; public CyclicIterator<T>(List<T> l) { this.l = l; this.it = l.iterator(); } public boolean hasNext() { return !l.isEmpty(); } public T next() { T ret; if (!hasNext()) { throw new NoSuchElementException(); } else if (it.hasNext()) { ret = it.next(); } else { it = l.iterator(); ret = it.next(); } return ret; } public void remove() { it.remove(); } }

  • .net Globalization and ResourceManager

    - by Andrew Bullock
    I've got a console app and i need to globalize some of the hardcoded message strings. I've got two assemblies: MyProgram.Console (Console app) MyProgram.Core (class lib) In MyProgram.Core I've made a Language.en-GB.resx and set it as an Embedded Resource. In the resource I've created a key/value pair: "SomeKey" : "SomeValue" When I build my application I get: bin/MyProgram.Console.exe bin/MyProgram.Core.dll bin/en-BG/MyProgram.Core.resources.dll How do I address these resource key/values? Currently I'm trying this from a class within MyProgram.Core: var mgr = new ResourceManager(GetType().Assembly.GetName().Name, Assembly.GetExecutingAssembly()); mgr.GetString("SomeKey", new Culture("en-GB")); But I keep getting: System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "MyProgram.Core.resources" was correctly embedded or linked into assembly "MyProgram.Core" at compile time, or that all the satellite assemblies required are loadable and fully signed. What am I doing wrong? I've tried every combination I can think of for the baseName argument to the ResourceManagers ctor. Thanks

  • Is it possible to template a template in WPF XAML?

    - by imekon
    Is it possible to use templates within templates? For instance, I have the following two templates: <HierarchicalDataTemplate x:Key="RecursiveTemplate" ItemsSource="{Binding Children}"> <StackPanel Margin="1" Orientation="Horizontal"> <Ellipse Fill="DarkGreen" Width="14" Height="14"/> <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate x:Key="ContainerTemplate" ItemsSource="{Binding Children}"> <StackPanel Margin="1" Orientation="Horizontal"> <Ellipse Fill="DarkBlue" Width="14" Height="14"/> <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> </StackPanel> </HierarchicalDataTemplate> There's a section of identical XAML: <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> Is it possible to move that to a resource and refer to it by name, rather than repeat it?

  • How to log correct context with Threadpool threads using log4net?

    - by myotherme
    I am trying to find a way to log useful context from a bunch of threads. The problem is that a lot of code is dealt with on Events that are arriving via threadpool threads (as far as I can tell) so their names are not in relation to any context. The problem can be demonstrated with the following code: class Program { private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); static void Main(string[] args) { new Thread(TestThis).Start("ThreadA"); new Thread(TestThis).Start("ThreadB"); Console.ReadLine(); } private static void TestThis(object name) { var nameStr = (string)name; Thread.CurrentThread.Name = nameStr; log4net.ThreadContext.Properties["ThreadContext"] = nameStr; log4net.LogicalThreadContext.Properties["LogicalThreadContext"] = nameStr; log.Debug("From Thread itself"); ThreadPool.QueueUserWorkItem(x => log.Debug("From threadpool Thread: " + nameStr)); } } The Conversion pattern is: %date [%thread] %-5level %logger [%property] - %message%newline The output is like so: 2010-05-21 15:08:02,357 [ThreadA] DEBUG LogicalContextTest.Program [{LogicalThreadContext=ThreadA, log4net:HostName=xxx, ThreadContext=ThreadA}] - From Thread itself 2010-05-21 15:08:02,357 [ThreadB] DEBUG LogicalContextTest.Program [{LogicalThreadContext=ThreadB, log4net:HostName=xxx, ThreadContext=ThreadB}] - From Thread itself 2010-05-21 15:08:02,404 [7] DEBUG LogicalContextTest.Program [{log4net:HostName=xxx}] - From threadpool Thread: ThreadA 2010-05-21 15:08:02,420 [16] DEBUG LogicalContextTest.Program [{log4net:HostName=xxx}] - From threadpool Thread: ThreadB As you can see the last two rows have no Names of useful information to distinguish the 2 threads, other than manually adding the name to the message (which I want to avoid). How can I get the Name/Context into the log for the threadpool threads without adding it to the message at every call?

  • How to run an external SWF inside a Flex Application?

    - by lk
    I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ private function loadSwfApplication() { var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf"); swfLoader.addEventListener(Event.COMPLETE, loadComplete); swfLoader.load(urlRequest); } private function loadComplete(completeEvent:Event) { var swfApplication:* = completeEvent.target.content; swfApplication.init(); // this is a Function that I made it in the Root class of swfApplication } ]]> </mx:Script> <mx:SWFLoader id="sfwLoader"/> </mx:WindowedApplication> The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception: Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf. This is because somewhere in application.swf I use the stage like this: if (root.stage != null) root.stage.addEventListener(Event.REMOVED, someFunction); root.stage.stageFocusRect = false; How can I load this swf application and USE the stage without any problems?

  • Threads in WCF service

    - by dragonfly
    Hi, there is a piece of code: class WCFConsoleHostApp : IBank { private static int _instanceCounter; public WCFConsoleHostApp () { Interlocked.Increment(ref _instanceCounter); Console.WriteLine(string.Format("{0:T} Instance nr " + _instanceCounter + " created", DateTime.Now)); } private static int amount; static void Main(string[] args) { ServiceHost host = new ServiceHost(typeof(WCFConsoleHostApp)); host.Open(); Console.WriteLine("Host is running..."); Console.ReadLine(); } #region IBank Members BankOperationResult IBank.Put(int amount) { Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Putting..."); WCFConsoleHostApp.amount += amount; Thread.Sleep(20000); Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Putting done"); return new BankOperationResult { CurrentAmount = WCFConsoleHostApp.amount, Success = true }; } BankOperationResult IBank.Withdraw(int amount) { Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Withdrawing..."); WCFConsoleHostApp.amount -= amount; Thread.Sleep(20000); Console.WriteLine(string.Format("{0:00} {1}", Thread.CurrentThread.ManagedThreadId, Thread.CurrentThread.IsThreadPoolThread) + " Withdrawing done"); return new BankOperationResult { CurrentAmount = WCFConsoleHostApp.amount, Success = true }; } #endregion } My test client application calls that service in 50 threads (service is PerCall). What I found very disturbing is when I added Thread.Sleep(20000) WCF creates one service instance per second using different thread from pool. When I remove Thread.Sleep(20000) 50 instances are instanciated straight away, and about 2-4 threads are used to do it - which in fact I consider normal. Could somebody explain why when Thread.Sleep causes those funny delays in creating instances?

  • Symfony fk issue on insertion

    - by Daniel Hertz
    Hi, I posted a similar problem but it could not be resolved. I create a relational database of users and groups but for some reason I cannot insert test data with fixtures properly.

  • Is this correct for disposing an object using IDisposable

    - by robUK
    I have a class that implements the IDisposable interface. I am using a webclient to download some data using the AsyncDownloadString. I am wondering have I correctly declared my event handlers in the constructor and within the using statement of the web client? And is this correct way to remove the event handlers in the Dispose method? Overrule is this the correct way to use the IDisposable interface? public class Balance : IDisposable { //Constructor WebClient wc; public Balance() { using (wc = new WebClient()) { //Create event handler for the progress changed and download completed events wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); } } ~Balance() { this.Dispose(false); } //Get the current balance for the user that is logged in. //If the balance returned from the server is NULL display error to the user. //Null could occur if the DB has been stopped or the server is down. public void GetBalance(string sipUsername) { //Remove the underscore ( _ ) from the username, as this is not needed to get the balance. sipUsername = sipUsername.Remove(0, 1); string strURL = string.Format("https://www.xxxxxxx.com", sipUsername); //Download only when the webclient is not busy. if (!wc.IsBusy) { // Download the current balance. wc.DownloadStringAsync(new Uri(strURL)); } else { Console.Write("Busy please try again"); } } //return and display the balance after the download has fully completed void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //Pass the result to the event handler } //Dispose of the balance object public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } //Remove the event handlers private bool isDisposed = false; private void Dispose(bool disposing) { if (!this.isDisposed) { if (disposing) { wc.DownloadProgressChanged -= new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged); wc.DownloadStringCompleted -= new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); wc.Dispose(); } isDisposed = true; } } }

  • ClassCastException while using service

    - by Sebi
    I defined a local Service: public class ComService extends Service implements IComService { private IBinder binder = new ComServiceBinder(); public class ComServiceBinder extends Binder implements IComService.IServiceBinder { public IComService getService() { return ComService.this; } } public void test(String msg) { System.out.println(msg); } @Override public IBinder onBind(Intent intent) { return binder; } } The corresponding interface: public interface IComService { public void test(String msg); public interface IServiceBinder { IComService getService(); } } Then i try to bind the service in another activity in another application, where the same interface is available: bindService(new Intent("ch.ifi.csg.games4blue.gamebase.api.ComService"), conn, Context.BIND_AUTO_CREATE); and private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.i("INFO", "Service bound " + name); comService = ((IComService.IServiceBinder)service).getService(); serviceHandler.sendEmptyMessage(0); } @Override public void onServiceDisconnected(ComponentName arg0) { Log.i("INFO", "Service Unbound "); } }; but the line comService = ((IComService.IServiceBinder)service).getService(); always throws a 05-02 22:12:55.922: ERROR/AndroidRuntime(622): java.lang.ClassCastException: android.os.BinderProxy I can't explain why, I followed the app sample on http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceBinding.html Any hints would be nice!

  • AppEngine JDO-QL : Problem with multiple AND and OR in query

    - by KlasE
    Hi, I'm working with App Engine(Java/JDO) and are trying to do some querying with lists. So I have the following class: @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") public class MyEntity { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key key; @Persistent List<String> tags = new ArrayList<String>(); @Persistent String otherVar; } The following JDO-QL works for me: ( tags.contains('a') || tags.contains('b') || tags.contains('c') || tags.contains('d') ) && otherVar > 'a' && otherVar < 'z' This seem to return all results where tags has one or more strings with one or more of the given values and together with the inequality search on otherVar But the following do not work: (tags.contains('a') || tags.contains('_a')) && (tags.contains('b') || tags.contains('_b')) && otherVar > 'a' && otherVar < 'z' In this case I want all hits where there is at least one a (either a or _a) and one b (either b or _b) together with the inequality search as before. But the problem is that I also get back the results where there is a but no b, which is not what I want. Maybe I have missed something obvious, or done a coding error, or possibly there is a restriction on how you can write these queries in appengine, so any tips or help would be very welcome.

  • Mapping composite foreign keys in a many-many relationship in Entity Framework

    - by Kirk Broadhurst
    I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

  • Is it okay to implement reference counting through composition?

    - by Billy ONeal
    Most common re-usable reference counted objects use private inheritance to implement re-use. I'm not a huge fan of private inheritance, and I'm curious if this is an acceptable way of handling things: class ReferenceCounter { std::size_t * referenceCount; public: ReferenceCounter() : referenceCount(NULL) {}; ReferenceCounter(ReferenceCounter& other) : referenceCount(other.referenceCount) { if (!referenceCount) { referenceCount = new std::size_t(1); other.referenceCount = referenceCount; } else { ++(*referenceCount); } }; ReferenceCounter& operator=(const ReferenceCounter& other) { ReferenceCounter temp(other); swap(temp); return *this; }; void swap(ReferenceCounter& other) { std::swap(referenceCount, other.referenceCount); }; ~ReferenceCounter() { if (referenceCount) { --(*referenceCount); if (!*referenceCount) delete referenceCount; } }; operator bool() const { return referenceCount && (*referenceCount != 0); }; }; class SomeClientClass { HANDLE someHandleThingy; ReferenceCounter objectsStillActive; public: SomeClientClass() { //Construct handle thingy } ~SomeClientClass() { if (objectsStillActive) return; //Release resources }; }; or are there subtle problems with this I'm not seeing?

  • WCF contracts - namespaces and SerializationExceptions

    I am using a third party web service that offers the following calls and responses http://api.athirdparty.com/rest/foo?apikey=1234 <response> <foo>this is a foo</foo> </response> and http://api.athirdparty.com/rest/bar?apikey=1234 <response> <bar>this is a bar</bar> </response> This is the contract and supporting types I wrote [ServiceContract] [XmlSerializerFormat] public interface IFooBarService { [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "foo?key={apikey}")] FooResponse GetFoo(string apikey); [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "bar?key={apikey}")] BarResponse GetBar(string apikey); } [XmlRoot("response")] public class FooResponse { [XmlElement("foo")] public string Foo { get; set; } } [XmlRoot("response")] public class BarResponse { [XmlElement("bar")] public string Bar { get; set; } } and then my client looks like this static void Main(string[] args) { using (WebChannelFactory<IFooBarService> cf = new WebChannelFactory<IFooBarService>("thirdparty")) { var channel = cf.CreateChannel(); FooResponse result = channel.GetFoo("1234"); } } When I run this I get the following exception Unable to deserialize XML body with root name 'response' and root namespace '' (for operation 'GetFoo' and contract ('IFooBarService', 'http://tempuri.org/')) using XmlSerializer. Ensure that the type corresponding to the XML is added to the known types collection of the service. If I comment out the GetBar operation from IFooBarService, it works fine. I know I'm missing an important concept here - just don't know quite what to look for. What is the proper way to construct my contract types, so that they can be properly deserialized?

  • How can I include additional markup within a 'Content' inner property within an ASP.Net WebControl?

    - by GenericTypeTea
    I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content;

  • Internet Explorer cannot 'fully' load ActiveX Control

    - by K Browne
    Context I am migrating an installer for an ActiveX control from Per-Machine to Per-User. I did this by programming the installer write to HKCU\Software\Classes instead of HKLM\Software\Classes. Problem On my machine (Windows 7 with UAC Enabled), the ActiveX control successfully loads. On the other windows 7 test machines (one with UAC enabled, one with UAC disabled), the control 'partially' loads. What is Partially? When a user visits a page with the ActiveX control, Internet Explorer displays a warning message in a yellow bar on the top of the window. If you click the 'Run add-on' button in the bar, the control becomes visible and begins to run, but Javascript code that tries to access properties of the control return the error: Library not registered. Differences between machines On the dev machine reads from HKCR\CLSID\<GUID> succeed while on the test machines these reads fail. Reads from HKCU succeed on both dev and test machines. Reads from HKLM fail on both test and dev machines. (I collected reads using Sysinternals Process Monitor) Strangely, the keys that Internet Explorer fails to read are clearly visible if I use regedit to view HKCR\CLSID\<GUID> on the test machines. Question What can I do to get the per-user control to load on the test machines? What could cause this difference between the dev machine and the test machines? Why can I see the key in HKCR with RegEdit but Internet Explorer cannot see the key? Any help is appreciated. Thank you.

  • SyntaxHighlighter and Line Break Tags

    - by azamsharp
    I am using the following syntax highligher: http://alexgorbatchev.com/wiki/SyntaxHighlighter For some reason when it encounter <br> it simply prints out <br> tags. I cannot replace the whole thing with System.Environment.NewLine since it will mess up the complete description. Here is my code: public static string GetDescription(string description) { string codeStartPattern = "&lt;code&gt;"; string codeEndPattern = "&lt;/code&gt;"; Regex reg = new Regex(codeStartPattern); description = reg.Replace(description, ReplaceWithStartDiv); reg = new Regex(codeEndPattern); description = reg.Replace(description, ReplaceWithEndDiv); return description; } private static string ReplaceWithStartDiv(Match m) { return "<script type='syntaxhighlighter' class='brush: csharp'><![CDATA["; } private static string ReplaceWithEndDiv(Match m) { return "]]></script>"; } I guess I only need to replace <br> with System.Environment.Newline with the code that is between the <code> snippet here </code> Thanks!

  • Upload image from Silverlight to ASP .net MVC 2.0 Action

    - by Raha
    Hello ... I have been trying really hard to Upload a photo from a Silverlight app to ASP .net MVC app. I simply use WebClient like this in Silverlight : private bool UploadFile(string fileName, Stream data) { try { UriBuilder ub = new UriBuilder("http://localhost:59933/Admin/Upload"); ub.Query = string.Format("filename={0}", fileName); WebClient wc = new WebClient(); wc.OpenReadCompleted += (sender, e) => { PushData(data, e.Result); e.Result.Close(); data.Close(); }; wc.OpenWriteAsync(ub.Uri); } catch (Exception) { throw; } return true; } private void PushData(Stream input, Stream output) { byte[] buffer = new byte[4096]; int byteRead; while ((byteRead = input.Read(buffer, 0, buffer.Length)) != 0) { output.Write(buffer, 0, byteRead); } } On the other hand I have created a simple action called Upload like this: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload() { //Some code here } The problem is that it doesn't hit the break point in Upload method. Is this even possible ? The reason why I am using Silverlight is that I want to preview the image before uploading it to server and it is very simple in Silverlight. I failed to do that in JavaScript and that is why Silverlight might be more useful here.

  • How do I create and use a junction table in Rails?

    - by Thierry Lam
    I have the following data: A post called Hello has categories greet Another post called Hola has categories greet, international My schema is: create_table "posts", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "categories", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "posts_categories", :force => true do |t| t.integer "post_id" t.integer "category_id" t.datetime "created_at" t.datetime "updated_at" end After reading the Rails guide, the most suitable relationship for the above seems to be: class Post < ActiveRecord::Base has_and_belongs_to_many :categories end class Category < ActiveRecord::Base has_and_belongs_to_many :posts end My junction table also seems to have a primary key. I think I need to get rid of it. What's the initial migration command to generate a junction table in Rails? What's the best course of action, should I drop posts_categories and re-create it or just drop the primary key column? Does the junction table have a corresponding model? I have used scaffold to generate the junction table code, should I get rid of the extra code? Assuming all the above has been fixed and is working properly, how do I query all posts and display them along with their named categories in the view. For example: Post #1 - hello, categories: greet Post #2 - hola, categories: greet, international
