    - Optional arguments consuming WCF service. Hi, I am using basicHttpBinding to create a WCF service that is being consumed from a Studio 2005 web service reference. All the scalar arguments to the method calls are accompanied by a bunch of horrible IsSpecified boolean arguments. If I wanted such a cludgy interface I would have added the booleans myself How do I specify that these arguments are in fact not optional The client code looks terrible. I wish to make the service nicely backward compatible. I have tried adding [WebMethod] attributes as it was suggested that it would help, but alas, it does not. Thanks Regards Craig Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - Connection Issues Hello We are experiencing some problems with connections to the server in one the applications of a customer. We have an scenario in which various clients connect to one server. As the server acknowledge clients of some operations we are using a custom dualHttp binding (it compress messages). < customBinding > < binding name = " DualHttpCompressionBinding " closeTimeout = " 00:00:30 " openTimeout = " 00:00:30 " receiveTimeout = " 23:59:59 " sendTimeout = " 00:01:00 " maxConnections = " 100 " > < reliableSession inactivityTimeout = " 00:10:00 " maxPendingChannels = " 128 " maxTransferWindowSize = " 40 " ordered = " false " /> < compositeDuplex /> < oneWay maxAcceptedChannels = " 100 " > < channelPoolSettings maxOutboundChannelsPerEndpoint = " 100 " /> </ oneWay > < gzipMessageEncoding innerMessageEncoding = " mtomMessageEncoding " /> < httpTransport useDefaultWebProxy = " false " /> </ binding > </ customBinding > As we need several clients, we have changed also the service throttling . < serviceThrottling maxConcurrentCalls = " 100 " maxConcurrentInstances = " 100 " maxConcurrentSessions = " 1000 " /> with this configuration we were able to connect only 25-30 PCs to the service. Other clients trying to reach the service throw this exception: “This request operation sent to http://acindar69/SSMWebHost/Service.svc did not receive a reply within the configured timeout (00:01:00). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still processing the operation or because the service was unable to send a reply message. Please consider increasing the operation timeout (by casting the channel/proxy to IContextChannel and setting the OperationTimeout property) and ensure that the service is able to connect to the client).” To solve this, we expose the same service in 2 different endpoints and configurate some clients to connect to one of the endpoints and the others to the other endpoint. Like this, we could run around 40 clients, but keep having the same exceptions when trying to connect some more. Although We have “solve” the problem for some number of clients, the solution is clearly not the best. We must create a new endpoint (exposing exactly the same service) for every 25-30 clients. My impression is that there must be some configuration limiting endpoints not to accept more than 30 connections. Any clue on how can we run more clients without adding new endpoints Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - DependencyProperty DataBinding and Thread I'm not following exactly what the problem is here -- but two suggestions: Take a look at a sample project I created a while back that does a bunch of bitmap manipulations, in threads, etc, all for the purpose of showing them in a ListBox. Some images contain thumbnails already, and if you can use those, it's a lot faster than creating them in code using the DecodePixelHeight/Width properties. http://www.wiredprairie.us/journal/2007/04/photoscroll_the_worst_named_wp.html Other thought was to Freeze the bitmap image your creating, if it's being created in another thread. If you don't, the main UI can't access it. Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - How to get, change, and save values from an entitiy using Entity Framework and LINQ? Hi all, for a project I have, my team decided to try working with Entity Framework and use LINQ to query the entities. To make my question more visible, I've also embedded a simplified code of our project which you can see below. We're using 3-Layer architecure (Presentation, Business, Data). The Main class below represented the Presentation Layer, and both getParticipant(...) and saveParticipant(...) methods are to be placed in the data layer. What I want to do here is : 1. Create a participant object in the presentation layer (Main class), using incomplete information (here in the sample the Participant_ID). 2. Get the rest of the information using a LINQ query in getParticipant(...) method, and save it to the created object. 3. Change the information of the entity and save it using saveParticipant(...) method As you can see, the context to the entity framework is only available in get and saveParticipant(...) methods of the data layer, this is intentional for security reasons. The problem arise when I call the saveParticipant(participant) method, practically forwarding the participant object to the "data layer". I don't know which method from the entity framework to call to incorporate the changes to the entities. I tried using "context.Attach(iParticipant);" to attach the input to the context, but then we get this error "Message="Entity can not be attached to multiple change trackers." eventhough I've detached them 1st in the getParticipant(...) method. I tried just using the context.AddToParticipant(iParticipant) method, but it failed by giving out "The entity cannot be added to the ObjectStateManager because it already has an EntityKey attached to it.", which is understandable I think the participant object have all the information needed for the entity framework to work with. any suggestion is very appreciated :-) Thanks in Advance, b4st -------------------------------------------------------------------------------- using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace test { class Program { static void Main(string[] args) { EntityFrameworkModel.Participant participant = new EntityFrameworkModel.Participant(); participant.Participant_Id = 1; participant = getParticipant(participant); participant.First_Name = "Pete"; saveParticipant(participant); } public static EntityFrameworkModel.Participant getParticipant(EntityFrameworkModel.Participant iParticipant) { using (EntityFrameworkModel.Entities context = new EntityFrameworkModel.Entities()) { var firstParticipant = (from fp in context.Participant where fp.Participant_Id == iParticipant.Participant_Id select fp); context.Detach(firstParticipant.First<EntityFrameworkModel.Participant>()); return firstParticipant.First<EntityFrameworkModel.Participant>(); } } public static void saveParticipant(EntityFrameworkModel.Participant iParticipant) { using (EntityFrameworkModel.Entities context = new EntityFrameworkModel.Entities()) { //... context.SaveChanges(); } } } } ---------------------------------------- Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - ClipToBounds property on Ellipse, Rectangle and Path Thanks again for the reply SerialSeb But this seems like a very very round about way of hacking the elements to fake an effect. It wouldn't be so bad if the elements on my page were static (i.e. not moving), but as soon as i want to animate the elements that fall within this imaginary shape, the system falls apart. Besides all of that it doesn't explain what an Ellipse, Rectangle and Path have the ClipToBounds property when it appears to do nothing. It would only work if you could nest objects within these given elements, but since you can not the property is useless. As far as i can see the whole point of ClipToBounds is so that you dont have to worry about making sure that one element has a clip set and then another element is laid over the top. The point is that you don’t have to worry about that, because when it comes to animation it would be near impossible and very impractical to continuously maintain that illusion. Thus the reason for ClipToBounds imho. Can you or anyone else out there explain to me why Ellipse, Rectangle and Path have the ClipToBounds property when you can't place elements within it Thanks all Anthony Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - Checking for a named pipe endpoint without throwing EndpointNotFoundException hi, yeah go with a mutext it's fast and should do the job, sorry about the InProcFactory, its been a while since I checked it out. a last option would be to query your endpoint using WMI, besides granting the right access to the process/user trying to query the endpoint you could use code like this : Code Snippet private bool IsRunning( string listenUri) { ConnectionOptions connection = new ConnectionOptions (); connection.Impersonation = ImpersonationLevel .Impersonate; connection.Authentication = AuthenticationLevel .Default; ManagementScope scope = new ManagementScope ( @"\\machinename\root\ServiceModel" , connection); scope.Connect(); ObjectQuery query = new ObjectQuery ( "SELECT * FROM Endpoint" ); ManagementObjectSearcher searcher = new ManagementObjectSearcher (scope, query); ManagementObjectCollection queryCollection = searcher.Get(); foreach ( ManagementObject m in queryCollection) { if (m[ "ListenUri" ].ToString() == listenUri) return true ; } return false ; } bool IsConnected = IsRunning( @"net.pipe://localhost/YourAppNameGoesHere/SingleInstance" ); Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - How to bind Background to RadialGradientBrush.Color? Thank you for a link, it looks useful... I have another question on this matter. How to work with dependency properties I have dependency property public class OwnProperties : Button { public OwnProperties() : base () {} public Color ClickedBackground { get { return ( Color ) this .GetValue(ClickedBackgroundProperty); } set { this .SetValue(ClickedBackgroundProperty, value ); } } public static readonly DependencyProperty ClickedBackgroundProperty = DependencyProperty .Register( "ClickedBackground" , typeof ( Color ), typeof ( Button ), new PropertyMetadata ( Colors .Gray)); } I referenced it in XAML: xmlns:own = " clr-namespace:WPFForm " and filled it in there: < Setter Property = " own:OwnProperties.ClickedBackground " Value = " #600 " /> I would like to bind it to Color property of RadialGradientBrush (see my example above). I thought the same way will work, but it does not. Why Is there any difference between built-in properties and newly added Or am I wrong with definition of dependency property RostaB Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - MenuItem.Command - multiple binding Hello, Setup: In my app, I have a MenuItem (mi) and I’ve hooked up a Command (cmd) to it. My app has a main window (win). The window has a frame (frm) that I use to navigate to page (pg1). In win.ctro I add a commandbinding for cmd. When I go to menu item and select the mi, the cmd fires. In pg1.ctor I have another commandbinding for cmd. Problem: When frm navigates to pg1, and I select the mi, the win.cmd fires not the pg1.cmd. My findings so far: a) I think this has to do with the CommandTarget setting. But I don’t seem to be able to give keyboard focus to the pg1 after it is loaded. Is ther a way I can do this b) I put a button btn on pg1 and set the btn.Command to the same binding as the mi. When I click the button, I get the pg1.cmd behavior. THEN if I click the mi I get the pg1.cmd behavior. So I thought if I set btn.IsDefault=true, I’ll somehow signal that it is the page that has focus. But it doesn’t work that way. I have to click the button and then pg1.cmd gets linked up to the mi. Thanks in advance.

    - IsTypeOf in msl's EntityTypeMapping? Hello! Let's assume EntityType C inherits from EntityType B which inherits from EntityType A. As far as I understand, the TypeName attribute in the EntityTypeMapping element should be specified with IsTypeOf and for C it should be specified without IsTypeOf, but what about the TypeName attribute in the EntityTypeMapping element for EntityType B, should it be specified with or without IsTypeOf Perhaps it would have been easier to figure out if the IsTypeOf construction had been documented.

    - Return large result sets using WCF with wsHttpBinding Hi, We are developing a new financial solution using WCF as communication programming model, in order to be accomplished with new customer requirements: SOA and interoperability. We have some WCF services (.svc) published in an Win2003/IIS6 server providing corporative services for some client applications. Since these client applications functionalities are built using composition of corporative services, all services are configured to use wsHttpBinding because we are using new transaction flow feature and also to guarantee interoperability with other WS* consumers. We are having problems when some services must return large results to client applications like financial transaction lists to be processed by those. We have already tried to configure these services with "Mtom" message encoding instead of "Text", we increased maxReceivedMessageSize parameter. We have done other configuration changes like defining readerCotas parameter, increase closeTimeout, sendTimeout, openTimeout parameters and nothing what we have done is making difference. When a list returned by services is larger than 1000 registers the exception below was thrown: An existing connection was forcibly closed by the remote host.

    - Running WPF applications in application domains Jennifer, Thank you for your reply. My reason for asking is not because I am developing a WPF application, but rather my app needs to support automating WPF applications. If Microsoft does not support running WPF apps in multiple AppDomains, then it is not necessary for my application to support it, either. Since it sounds like the current plan is to support this using .NET 3.5, my application should support it in that case as well.

I then updated my XAML to (without the space trailing x : DataContext="{x: Static Member=local:FooBarClass.StaticFooList}" At runtime, when Control.OnInitialized gets called in FooBarClass, I get the following error: "Cannot convert the value in attribute 'DataContext' to object of type 'System.Windows.Markup.StaticExtension'. Error at object 'System.Windows.Controls.ControlTemplate', Line 26 Position 33." The same happened when I tried binding the ItemSource attribute (its a ListBox). The web offered no suggestions as to what caused the problem. I played around binding it to other static properties of various data types. Simple things like strings did not produce the error. However for a listbox, binding the ItemsCollection to a string is not very useful. Is there a way to get this to work with a collection Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - Garbage Collection. With TreeView, ListBox, etc This may also help a lot. In fact, I am using an extended TreeViewItem where I add an image and a text box. So maybe have these freezable objects are not frozen. Truly, I really dont know what the Freezable properties are, but I will learn and find out if your solution helped Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

    - HostVisual and VisualTarget Hello all, We've been working away at getting HostVisual and VisualTarget working, and I'm hoping someone out there can give us a little more insight. At this point we are inheriting from FrameworkElement and using DrawingVisual and HostVisual to host a MediaPlayer. The next step, rigging up VisualTarget and getting a secondary thread on the go, is where we're at a loss. Below is the code we currently have; I've included the important bits. If you want to test this, just comment out the event handlers and come up with a WMV file. Code Snippet public class HostedMediaPlayer : FrameworkElement { public event EventHandler<MediaEventData> ErrorHappened; DrawingVisual _dv = null; HostVisual _hv = null; public HostedMediaPlayer() { _dv = new DrawingVisual(); _hv = new HostVisual(); MediaPlayer mp = new MediaPlayer(); // rig up the Media Player mp.MediaFailed += new EventHandler<ExceptionEventArgs>(mp_MediaFailed); mp.Open(new Uri(@"C:\video\test.wmv")); mp.MediaEnded += new EventHandler(mp_MediaEnded); // tie the video to the DrawingVisual's context using (DrawingContext dc = _dv.RenderOpen()) { dc.DrawVideo(mp, new Rect(0, 0, 320, 240)); } // configure the HostVisual to host the DrawingVisual and add it // to the FrameworkElement's visual/logical children _hv.Children.Add(_dv); AddVisualChild(_hv); AddLogicalChild(_hv); // start the video mp.Play(); } //<snipped MediaPlayer event handlers /> protected override int VisualChildrenCount { get { return 1; } } protected override Visual GetVisualChild(int index) { if (index != 0) throw new ArgumentOutOfRangeException("index"); return _hv; } } This code works just fine. In fact, if you create an instance of the above class and put it on a WPF form the video plays almost instantly. We know that VisualTarget accepts a HostVisual as a param in the constructor, but this doesn't really clarify the roles each play to each other. My questions would be as follows: 1) how do you involve VisualTarget from here 2) where does the secondary thread come from Any help is appreciated.

    - Invalid association mapping error in Add() I just ingested a Schema using the a Linq to SQL DBML file in the designer. All looked good and seemed to be properly referenced. Then i tried to add a row to a lookup table like below: Code Snippet using (MyDataContext db = new MyDataContext(ConfigurationManager.ConnectionStrings["MyDB"].ConnectionString)) { track_status_enum x = new track_status_enum(); x.enum_value = TrackStatus.Archive.ToString(); x.track_status_id = (byte)TrackStatus.Archive; feed_item_comment_track f = null; db.track_status_enums.Add(x); db.SubmitChanges(); This resulted in the following error on the Add() line: Invalid association mapping for member 'Feedelity.DAL.track_status_enum.feed_item_comment_tracks'. 'Feedelity.DAL.feed_item_comment_track' is not an entity. track_status_enum is a lookup referenced by a bunch of tables as a status field and feed_item_comment_track is one of them. Since i wasn't adding anything to those tables, I don't even know why it's interacting with them on this add, anyhow, but regardless, feed_item_comment_track is defined the same as track_status_enum, so i expect it to be an entity for linq. Any suggestions what this error actually means and where to start troubleshooting thanks arne Tag: Windows Presentation Foundation (WPF) g.i.cs-Files in WPF-Projects in Visual Studio 2008 Visual Studio 2008

In Visual Studio 2008 Beta 2 I saw in a standard WPF Application, that there are not only the generated Files App.g.cs and Window1.g.cs, there are also App.g.i.cs and Window1.g.i.cs.

Are the g.i.cs only for the Intellisense-Support in Codebehind-Files without the need to rebuild the solution

What stands the "i" for

I've found no documentation about this, and im just interested in and would be very glad about a hint.

Maybe an additional information. The g.i.cs-Files are only visible in the Solution Explorer, select "Show all Files" and browse to the obj\Debug-Folder.

You won't see the g.i.cs-Files in FileSystem, cause it seems that they are generated and then deleted.

The .g.i.<lang-specific extension.> are used internally to provide various Visual Studio features including intellisense. The files don't appear in the obj directory because they are generated in memory.
