  • what's wrong with sql statements sqlite3_column_text ??

I have one table and one row in my db relatively, id (integer), name (varchar), desc (varchar) (I created my table using SQLite Manager). 2-) What is text type in SQLite Manager? Is that NSString? Also how can I put the string values(in table) to an NSMutableArray ?

  • MS SQL 2008, join or no join?

    - by Patrick
    Just a small question regarding joins. I have a table with around 30 fields and i was thinking about making a second table to store 10 of those fields. Then i would just join them in with the main data. The 10 fields that i was planning to store in a second table does not get queried directly, it's just some settings for the data in the first table. Something like: Table 1 Id Data1 Data2 Data3 etc ... Table 2 Id (same id as table one) Settings1 Settings2 Settings3 Is this a bad solution? Should i just use 1 table? How much performance inpact does it have? All entries in table 1 would also then have an entry in table 2. Small update is in order. Most of the Data fields are of the type varchar and 2 of them are of the type text. How is indexing treated? My plan is to index 2 data fields, email (varchar 50) and author (varchar 20). And yes, all records in Table 1 will have a record in Table 2. Most of the settings fields are of the bit type, around 80%. The rest is a mix between int and varchar. The varchars can be null.

  • Integration test failing through NUnit Gui/Console, but passes through TestDriven in IDE

    - by Cliff
    I am using NHibernate against an Oracle database with the NHibernate.Driver.OracleDataClientDriver driver class. I have an integration test that pulls back expected data properly when executed through the IDE using TestDriven.net. However, when I run the unit test through the NUnit GUI or Console, NHibernate throws an exception saying it cannot find the Oracle.DataAccess assembly. Obviously, this prevents me from running my integration tests as part of my CI process. NHibernate.HibernateException : The IDbCommand and IDbConnection implementation in the assembly Oracle.DataAccess could not be found. Ensure that the assembly Oracle.DataAccess is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly.* I have tried making the assembly available in two ways, by copying it into the bin\debug folder and by adding the element in the config file. Again, both methods work when executing through TestDriven in the IDE. Neither work when executing through NUnit GUI/Console. The NUnit Gui log displays the following message. 21:42:26,377 ERROR [TestRunnerThread] ReflectHelper [(null)]- Could not load type Oracle.DataAccess.Client.OracleConnection, Oracle.DataAccess. System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies.

  • Castle Windsor and its own configuration file

    - by Coppermill
    I am using Castle Windsor for IoC, and have the configuration held in the web.config/app.config, using the following factory: public static TYPE Factory(string component) { var windsorContainer = new WindsorContainer(new XmlInterpreter()); var service = windsorContainer.Resolve<TYPE>(component); if (service == null) throw new ArgumentNullException(string.Format("Unable to find container {0}", component)); return service; } and my web.config looking like this: <configuration> <configSections> <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor"/> </configSections> <castle> <components> <component id="Data" service="Data.IData, Data" type="Data.DataService, Data"/> </components> </castle> <appSettings>....... Which works fine, but I'd like to place the configuration for Castle Windsor in a file called castle.config. How do I do this?

  • nhibernate will not cascade delete childs

    - by marn
    The scenario is as follows, I have 3 objects (i simplified the names) named Parent, parent's child & child's child parent's child is a set in parent, and child's child is a set in child. mapping is as follows (relevant parts) parent <set name="parentset" table="pc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column=FK_ID_PC" on-delete="cascade"/> <one-to-many class="parentchild,parentchild-ns"/> </set> parent's child <set name="childset" table="cc-table" lazy="false" fetch="subselect" cascade="all-delete-orphan" inverse="true"> <key column="FK_ID_CC" on-delete="cascade"/> <one-to-many class="childschild,childschild-ns"/> </set> What i want to achieve is that when i delete the parent, there would be a cascade delete all the way trough to child's child. But what currently happens is this. (this is purely for mapping test purposes) getting a parent entity (works fine) IQuery query = session.CreateQuery("from Parent where ID =" + ID); IParent doc = query.UniqueResult<Parent>(); now the delete part session.Delete(doc); transaction.Commit(); After having solved the 'cannot insert null value' error with cascading and inverse i hopes this would now delete everything with this code, but only the parent is being deleted. Did i miss something in my mapping which is likely to be missed? Any hint in the right direction is more than welcome!

  • memory warning, generating UIImagefrom pdf files in objective-c

    - by favo
    When converting PDF Pages into UIImages I receive memory warnings all the time. It seems there is either some leak or something else that eats my memory. Using instruments didn't give me any helpful details. I'm using the following function to generate images from a pdf file: - (UIImage*)pdfImage:(NSString*)pdfFilename page:(int)page { CFURLRef pdfURL = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, (CFStringRef)pdfFilename, kCFURLPOSIXPathStyle, false); CGPDFDocumentRef pdfRef = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CFRelease(pdfURL); CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfRef, page); CGRect pdfPageSize = CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox); float pdfScale; if ( pdfPageSize.size.width < pdfPageSize.size.height ) { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.width; } else { pdfScale = PDF_MIN_SIZE / pdfPageSize.size.height; } CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, pdfPageSize.size.width*pdfScale, pdfPageSize.size.height*pdfScale, 8, (int)pdfPageSize.size.width*pdfScale * 4, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); // CGContextClipToRect(context, pdfPageView.frame); // CGPDFPageRetain(pdfPage); CGAffineTransform transform = aspectFit(CGPDFPageGetBoxRect(pdfPage, kCGPDFBleedBox), CGContextGetClipBoundingBox(context)); CGContextConcatCTM(context, transform); CGContextDrawPDFPage(context, pdfPage); // CGPDFPageRelease (pdfPage); CGImageRef image = CGBitmapContextCreateImage(context); CGContextRelease(context); UIImage *finalImage = [UIImage imageWithCGImage:image]; CGImageRelease(image); CGPDFDocumentRelease(pdfRef); return finalImage; } I am releasing the document and everything else, so where could be the problem? Thanks for your help!

  • Relation between [[Prototype]] and prototype in JavaScript

    - by Claudiu
    From http://www.jibbering.com/faq/faq_notes/closures.html : Note: ECMAScript defines an internal [[prototype]] property of the internal Object type. This property is not directly accessible with scripts, but it is the chain of objects referred to with the internal [[prototype]] property that is used in property accessor resolution; the object's prototype chain. A public prototype property exists to allow the assignment, definition and manipulation of prototypes in association with the internal [[prototype]] property. The details of the relationship between to two are described in ECMA 262 (3rd edition) and are beyond the scope of this discussion. What are the details of the relationship between the two? I've browsed through ECMA 262 and all I've read there is stuff like: The constructor’s associated prototype can be referenced by the program expression constructor.prototype, Native ECMAScript objects have an internal property called [[Prototype]]. The value of this property is either null or an object and is used for implementing inheritance. Every built-in function and every built-in constructor has the Function prototype object, which is the initial value of the expression Function.prototype Every built-in prototype object has the Object prototype object, which is the initial value of the expression Object.prototype (15.3.2.1), as the value of its internal [[Prototype]] property, except the Object prototype object itself. From this all I gather is that the [[Prototype]] property is equivalent to the prototype property for pretty much any object. Am I mistaken?

  • Encoding issue: Cocoa Error 261?

    - by Attacus
    So I'm fetching a JSON string from a php script in my iPhone app using: NSURL *baseURL = [NSURL URLWithString:@"test.php"]; NSError *encodeError = [[NSError alloc] init]; NSString *jsonString = [NSString stringWithContentsOfURL:baseURL encoding:NSUTF8StringEncoding error:&encodeError]; NSLog(@"Error: %@", [encodeError localizedDescription]); NSLog(@"STRING: %@", jsonString); The JSON string validates when I test the output. Now I'm having an encoding issue. When I fetch a single echo'd line such as: { "testKey":"é" } (I'm aware I could\should be using NSUrlConnection for asynchronous fetching of data, but at this point in the app development, I don't really need it.) The JSON parser works fine and I am able to create a valid JSON object. However, when I fetch my 2MB JSON string, I get presented with: Error: Operation could not be completed. (Cocoa error 261.) and a Null string. My PHP file is UTF8 itself and I am not using utf8_encode() because that seems to double encode the data since I'm already pulling the data as NSUTF8StringEncoding. Either way, in my single-echo test, it's the approach that allowed me to successfully log \ASDAS style UTF8 escapes when building the JSON object. What could be causing the error in the case of the larger string? Also, I'm not sure if it makes a difference, but I'm using the php function addslashes() on my parsed php data to account for quotes and such when building the JSON string.

  • Accessing Request object from custom JSP tags

    - by Byron
    I'm trying to make a set of custom tags that encapsulate form elements (markup and validation). There's a method given to retrieve the "Out" object easily: JspWriter out = getJspContext().getOut(); However I can't figure out how to get the request object. I want to be able to directly access the submitted form values from within the Tag class so that I can validate each field. The documentation is quite sparse, so I thought maybe I could use the JspContext object to somehow get the request attributes. But I don't understand the different scopes. System.out.println(getJspContext().findAttribute("field1")); always prints "null". Enumeration e = getJspContext().getAttributeNamesInScope(1); Looping through and printing out the enumeration just gives me a list of classes that don't exist: javax.servlet.jsp.jspOut javax.servlet.jsp.jspPage javax.servlet.jsp.jspSession javax.servlet.jsp.jspApplication javax.servlet.jsp.jspPageContext javax.servlet.jsp.jspConfig javax.servlet.jsp.jspResponse javax.servlet.jsp.jspRequest So is this even possible? If not, could anyone point me to a tag library that deals with form display and validation? I searched the internet for a couple hours and it seemed every single one was discontinued and I couldn't download them. Either that or suggest a better alternative for handling forms.

  • When programatically creating a new IIS web site, how can I add it to an existing application pool?

    - by Ian Robinson
    I have successfully automated the process of creating a new IIS website, however the code I've written doesn't care about application pools, it just gets added to DefaultAppPool. However I'd like to add this newly created site to an existing application pool. Here is the code I'm using to create the new website. var w3Svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", webserver)); var newsite = new object[] { serverComment, new object[] { serverBindings }, homeDirectory }; var websiteId = w3Svc.Invoke("CreateNewSite", newsite); site.Invoke("Start", null); site.CommitChanges(); <update Although this is not directly related to the question, here are some sample values being used above. This might help someone understand exactly what the code above is doing more easily. webServer: "localhost" serverComment: "testing.dev" serverBindings: ":80:testing.dev" homeDirectory: "c:\inetpub\wwwroot\testing\" </update If I know the name of the application pool that I'd like this web site to be in, how can I find it and add this site to it? <update 2 I've added the following based on Mark's answer below. var appPool = new DirectoryEntry(string.Format("IIS://{0}/w3svc/AppPools/{1}", webServer, appPoolName)); site.Properties["AppPoolId"].Value = appPool; I seem to have moved passed the "RPC" error message I was initially receiving. Now this is the error message I'm receiving: Error: System.Runtime.InteropServices.COMException (0x8000500C): Exception from HRESULT: 0x8000500C at System.DirectoryServices.Interop.UnsafeNativeMethods.IAds.PutEx(Int32 lnControlCode, String bstrName, Object vProp) at System.DirectoryServices.PropertyValueCollection.set_Value(Object value) at ProvisionIISWebsite.Query.CreateWebsite(String webServer, String serverComment, String serverBindings, String homeDirectory, String appPoolName) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 104 at ProvisionIISWebsite.Query.Handle_GetData(EngineBase& caller, Boolean isSubQuery, String query, String filterField, String filterText, Debugger& debugWriter, Boolean isRendered, Int32 timeout, String customConnection) in C:\Users\irobinson\My Projects\ProvisionIISWebsite\Query.cs:line 36 </update 2

  • Unit testing Monorail's RenderText method

    - by MikeWyatt
    I'm doing some maintenance on an older web application written in Monorail v1.0.3. I want to unit test an action that uses RenderText(). How do I extract the content in my test? Reading from controller.Response.OutputStream doesn't work, since the response stream is either not setup properly in PrepareController(), or is closed in RenderText(). Example Action public DeleteFoo( int id ) { var success= false; var foo = Service.Get<Foo>( id ); if( foo != null && CurrentUser.IsInRole( "CanDeleteFoo" ) ) { Service.Delete<Foo>( id ); success = true; } CancelView(); RenderText( "{ success: " + success + " }" ); } Example Test (using Moq) [Test] public void DeleteFoo() { var controller = new FooController (); PrepareController ( controller ); var foo = new Foo { Id = 123 }; var mockService = new Mock < Service > (); mockService.Setup ( s => s.Get<Foo> ( foo.Id ) ).Returns ( foo ); controller.Service = mockService.Object; controller.DeleteTicket ( foo.Id ); mockService.Verify ( s => s.Delete<Foo> ( foo.Id ) ); Assert.AreEqual ( "{success:true}", GetResponse ( Response ) ); } // response.OutputStream.Seek throws an "System.ObjectDisposedException: Cannot access a closed Stream." exception private static string GetResponse( IResponse response ) { response.OutputStream.Seek ( 0, SeekOrigin.Begin ); var buffer = new byte[response.OutputStream.Length]; response.OutputStream.Read ( buffer, 0, buffer.Length ); return Encoding.ASCII.GetString ( buffer ); }

  • Youtube API - How to limit results for pagination?

    - by worchyld
    I want to grab a user's uploads (ie: BBC) and limit the output to 10 per page. Whilst I can use the following URL: http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10 The above works okay. I want to use the query method instead: The Zend Framework docs: http://framework.zend.com/manual/en/zend.gdata.youtube.html State that I can retrieve videos uploaded by a user, but ideally I want to use the query method to limit the results for a pagination. The query method is on the Zend framework docs (same page as before under the title 'Searching for videos by metadata') and is similar to this: [code] $yt = new Zend_Gdata_YouTube(); $query = $yt-newVideoQuery(); $query-setTime('today'); $query-setMaxResults(10); $videoFeed = $yt-getUserUploads( NULL, $query ); // Output print ''; foreach($videoFeed as $video): print '' . $video-title . ''; endforeach; print ''; [/code] The problem is I can't do $query-setUser('bbc'). I tried setAuthor but this returns a totally different result. Ideally, I want to use the query method to grab the results in a paginated fashion. How do I use the $query method to set my limits for pagination? Thanks.

  • Overlay only draws line between first 2 GPS points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Binding property to Silverlight dependency property independent of DataContext

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

  • cURL gets response with utf-8 BOM

    - by Reshat Belyalov
    In my script I send data with cURL, and enabled CURLOPT_RETURNTRANSFER. The response is json encoded data. When I'm trying to json_decode, it returns null. Then I found that response contains utf-8 BOM symbols at the beginning of string (). There is some experiments: $data = $data = curl_exec($ch); echo $data; the result is {"field_1":"text_1","field_2":"text_2","field_3":"text_3"} $data = $data = curl_exec($ch); echo mb_detect_encoding($data); result - UTF-8 $data = $data = curl_exec($ch); echo mb_convert_encoding($data, 'UTF-8', mb_detect_encoding($data)); // identical to echo mb_convert_encoding($data, 'UTF-8', 'UTF-8'); result - {"field_1":"text_1","field_2":"text_2","field_3":"text_3"} The one thing that helps is removing first 3 symbols: if (substr($data, 0, 3) == pack('CCC', 239, 187, 191)) { $data = substr($data, 3); } But what if there will be another BOM? So the question is: How to detect right encoding of cURL response? OR how to detect what BOM has arrrived? Or maybe how to convert the response with BOM? Thanks.

  • ASP.NET Membership ChangePassword control - Need to check for previous password

I need to tell the user that this password was used and pic a new one. I can't seem to be able to interrupt the control from changing the password. Maybe I am using the wrong event.

I've got the following code which I've tried to port from objective-c, however I've got stuck on the last parts. Original Objective-C. This may not be the best way of achieving what I want to do - any solution is fine for me. int width = 100; int height = 100; using (UIImage image = UIImage.FromFile(filePath)) { CGImage cgimage = image.CGImage; CGImageAlphaInfo alphaInfo = cgimage.AlphaInfo; if (alphaInfo == CGImageAlphaInfo.None) alphaInfo = CGImageAlphaInfo.NoneSkipLast; CGBitmapContext context = new CGBitmapContext(IntPtr.Zero, width, height, cgimage.BitsPerComponent, 4 * width, cgimage.ColorSpace, alphaInfo); context.DrawImage(new RectangleF(0, 0, width, height), cgimage); /* Not sure how to convert this part: CGImageRef ref = CGBitmapContextCreateImage(bitmap); UIImage* result = [UIImage imageWithCGImage:ref]; CGContextRelease(bitmap); // ok if NULL CGImageRelease(ref); */ }

  • Entity Framework, Foreign Keys and EntityKeys

    - by Greg
    I've got a problem with the Entity Framework and the ForeignKeys. I've got a table "BC_Message_Assets" which has 3 FK's (MessageId, AssetId and StatusId). I create my "MessageAsset" like this MessageAsset messageAsset = new MessageAsset(); messageAsset.MessageStatusReference.EntityKey = new EntityKey("MyEntities.MessageStatusSet", "Id", 1); messageAsset.AssetReference.EntityKey = new EntityKey("MyEntities.AssetSet", "Id", 1); messageAsset.MessageReference.EntityKey = new EntityKey("MyEntities.MessageSet", "Id", messageId); context.AddToMessageAssetSet(messageAsset); context.SaveChanges(); But I got the following exception : The INSERT statement conflicted with the FOREIGN KEY constraint \"FK_BC_Message_Assets_BC_Assets\". The conflict occurred in database \"Test\", table \"dbo.BC_Assets\", column 'Id'.\r\nThe statement has been terminated. When I look at the query, I notice that the parameter value for AssetId is "0" despite that I provided "1" to the EntityKey. Here's the generated query : exec sp_executesql N'insert [dbo].[BC_Message_Assets]([MessageId], [AssetId], [CompletionTime], [StatusId]) values (@0, @1, null, @2) ',N'@0 int,@1 int,@2 int',@0=47,@1=0,@2=1 I can't explain what happens. I hardcoded "1" in the EntityKey and I received "0" in the query ?

  • C# - Get values of static properties from static class

    - by JamesW
    I'm trying to loop through some static properties in a simple static class in order to populate a combo box with their values, but am having difficulties. Here is the simple class: public static MyStaticClass() { public static string property1 = "NumberOne"; public static string property2 = "NumberTwo"; public static string property3 = "NumberThree"; } ... and the code attempting to retrieve the values: Type myType = typeof(MyStaticClass); PropertyInfo[] properties = myType.GetProperties( BindingFlags.Public | BindingFlags.Static | BindingFlags.DeclaredOnly); foreach (PropertyInfo property in properties) { MyComboBox.Items.Add(property.GetValue(myType, null).ToString()); } If I don't supply any binding flags then I get about 57 properties including things like System.Reflection.Module Module and all sorts of other inherited things I don't care about. My 3 declared properties are not present. If I supply various combinations of other flags then it always returns 0 properties. Great. Does it matter that my static class is actually declared within another non-static class? Please help! What am I doing wrong?

  • Setting custom WCF-binding behaviour via .config file - why doesn't this work?

    - by Andrew Shepherd
    I am attempting to insert a custom behavior into my service client, following the example here. I appear to be following all of the steps, but I am getting a ConfigurationErrorsException. Is there anyone more experienced than me who can spot what I'm doing wrong? Here is the entire app.config file. <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ClientLoggingEndpointBehaviour"> <myLoggerExtension /> </behavior> </endpointBehaviors> </behaviors> <extensions> <behaviorExtensions> <add name="myLoggerExtension" type="ChatClient.ClientLoggingEndpointBehaviourExtension, ChatClient, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"/> </behaviorExtensions> </extensions> <bindings> </bindings> <client> <endpoint behaviorConfiguration="ClientLoggingEndpointBehaviour" name="ChatRoomClientEndpoint" address="http://localhost:8016/ChatRoom" binding="wsDualHttpBinding" contract="ChatRoomLib.IChatRoom" /> </client> </system.serviceModel> </configuration> Here is the exception message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'myLoggerExtension' cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. Parameter name: element (C:\Documents and Settings\Andrew Shepherd\My Documents\Visual Studio 2008\Projects\WcfPractice\ChatClient\bin\Debug\ChatClient.vshost.exe.config line 5) I know that I've correctly written the reference to the ClientLoggingEndpointBehaviourExtensionobject, because through the debugger I can see it being instantiated.
