    - g.i.cs-Files in WPF-Projects in 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.

    - ListViewColumnHeader Hello, do you want to filter the data based on what the user types in the TextBox If so, I guess what you want is the TextBox’s Text property. Since the TextBox is in a template, we can’t get it directly in the code. But here’s a walk around: Create a TextBlock outside the template, set its Visibility property to Collapsed, so the user won’t see it. Give it a name such as text1. Now we can bind the TextBox’s Text in the template to the TextBlock’s Text: Text = " {Binding ElementName=text1, Path=Text} " Since this binding is two way by default, whenever the TextBox’s Text updates, the TextBlock’s Text will also be updated. And we can access the TextBlock in our code since it’s not in a template. So we’ll get the text the user typed.

    - 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.

    - Wrapping a DependencyProperty with a static property I would like a singleton source. But since dependency properties keep a reference to the data, I suppose I would need a singleton destination as well. It seems with the existing implementation, a singleton destination is not achievable. Is there some way of defining a singleton source I attempted making my class a singleton, but the XAML complained about instantiating a Control without a public ctor.

    - 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) How to get the screen resolution in wpf Visual Studio 2008

    - Simple POX example The "{d:}" is a format used between a WCF service and an ASP.NET AJAX client. If you don't want this, you should not use the <enableWebScript> behavior element, but the <webHttp> element, as shown in my previous post on this thread. By default, <enableWebScript> endpoints have request/response format set to JSON, and <webHttp> endpoints have request/response format set to XML.

    - WsHttpBinding Transport security wsdl Address location We have recently been trying to move an existing service to use Transport security with Basic authentication. There is a deployed service http://dev.services.companyname.com/ServiceName.svc for which I can view in IE7 both at http and https urls. However, when the proxy is generated from the secure address, and when the wsdl is viewed from the secure address some of urls change to https://computername.domainname/ServiceName.svc , so when a request is made for an endpoint it cannot find the endpoint and gets a 404 on the soap action because the certificate does not validate against the latter url. Am I missing a setting somewhere I'm confused where it picks up the computer name for the URL because nowhere do I reference that computername.

    - WCF - Multiple Channel Implementation One solution that will work is to create a separate endpoint/client. This isn't a bad idea if the number of clients is constrained. If the number isn't constrained or is too large to make sense, you can insert a header into each message identifying the 'session' by making the Chunking channel emit a System.Xml.UniqueId identifying the session. Then, you can change the chunking channel to reassemble the messages based on UniqueId. When all the messages for a given UniqueId are pulled from the queue, you can notify the channel up the stream.

    - Linq in Windows and Web Sites It looks like you are trying to query on a single element rather than an IEnumerable<T> type. Try changing the query to From el in xml.<ProductID> select. Looking at your XML, shouldn't your PurchaseOrder contain PurchaseItem elements which then contian the ProductID, ProductQuantity items If so, your query could then become "From el in xml.<ProductItem> select Id=el.<ProductID>, Quantity=el.<ProductQuantity>.

    - Communication between applications in same machine. Hi, I have a requirement to pass massages between windows applications developed on .NET 3.0, deployed on the same machine. The requirements are 1. 2 way communication between the applications. App # 1 should pass a message to App # 2 and in return App # 1 should get back response. 2. App # 2 should send a message back to the caller App (in this case App # 1). I was considering System.Diagnostics and win32 ShellExec. But recently i came across WCF. I was wondering if any one tried their hands in WCF for interprocess communication. Can some one please let me know if WCF is a good fit for my requirement and also, if there are any samples to demostrate it, please let me know. Note: I am planning to use WPF to develop the windows applications. Thanks in advace.

    - Multiple Endpoints Sample Broken Thank you for the reply, I tried switching the endpoint to use BasicHttpBinding as you mentioned, but unfortunately it had no effect.

    - Use alternative listbox colors I want to alter the colors of the listbox. If I hover the mouse above an item it should have a 'LightBlue' background. If I select it, then it should become 'Orange'. I thought that the following code would work (try XamlPad). Hovering works fine, but 'ListBoxItem' uses an internal border (called 'Bd') that draws over my own background. I think I need to alter the style of the internal border.

    - Opacity Mask problems http://msdn2.microsoft.com/en-us/library/system.windows.uielement.snapstodevicepixels.aspx You can set this property to true on your root element to enable pixel snap rendering throughout the UI. For devices operating at greater than 96 dots per inch (dpi), pixel snap rendering can minimize anti-aliasing visual artifacts in the vicinity of single-unit solid lines. When inherited by FrameworkElement or any possible derived classes, FrameworkElement overrides the metadata for this dependency property to set the Inherits metadata property to true . What this achieves is that only the outermost element in a subtree needs to specify SnapsToDevicePixels as true , and all child elements of that subtree will then report SnapsToDevicePixels as true and will have the SnapsToDevicePixels visual effect.

    - Transport Security + Windows Authentication + Workgroup Mode Service and Client Hosts Would anyone please let me know how I can use Windows Authentication to achieve Transport Security between Workgroup mode service and client hosts. The objective is to have both service and client executing as a windows service running on workgroup mode servers.

    - No codec found that can decode the specified file? Hi, I get the same error (using Feb 06 bits) with a rather simple example: BitmapFrame bf = BitmapFrame .Create( new Uri ( @"C:\WINREP.ico" )); and explicitly using the IconBitmapDecoder results in the same error: IconBitmapDecoder ibd = new IconBitmapDecoder ( new Uri ( @"C:\WINREP.ico" ), BitmapCreateOptions .None, BitmapCacheOption .None); I've copied WINREP.ico from the windows directory to C:\ for simplicity. Seems not to work with any other icon file. Performing the same with e.g. jpg images works perfectly fine.

    - Relationship between UI composition and code-behind Fernando, your bindings are relative to the DataContext in the hierarchy of your objects. The easiest and most straightforward way to achieve this is to set the object itself as its own DataContext. You'd end up with a Page constructor with this.DataContext = this. You can then bind to properties you've defined on your Page code-behind. These proeprties, to be bound and for your element graph to react automatically and adapt when they change, needs to be either dependency properties, or your page can implement INotifyPropertyChange. It is then possible for you to set your property to null, and load your data on another thread. When the data is loaded, you notify of the change through raising the PropertyChanged event of the INotifyPropertyChanged interface, making sure you only do it on the UI thread (through using the dispatcher). (In all honesty, bindings knows how to marshall to the correct thread for INotifyPropertyChanged but not for INotifyCollectionChanged, so it's very much optional. Still, it's good practice.) And as the complexity of your solution increases, you can refactor to keep your data in a ViewModel class implementing INotifyPropertyChanged and assigin the DataContext to this ViewModel instead.

    - Strong typed DataTables in Entity Hey! We have a class library(SharedDataTypes.dll) that consists of classes, this classlibrarys is referenced in both the Host (Where the Data Contract is) and the client. By using /r haredDataTypes.dll with svcutil when auto generating the proxy we are able to fille the Rich types on the client side when data is received. Now we need all the Strong Typed DataTabels in our DAL to be a part of this shared class library to be able to send data from host to client and use the typed datatabels on the client. The Strong Typed DataTabels are generated by visual studio in the DAL and are by that including adapters that we don't want to have in our shared class library(becource thay have connections direct to the database). How can we include the strong typed datatabels in our shared class library Best Regards Jimmy Tag: Windows Presentation Foundation (WPF) How to get the screen resolution in wpf Visual Studio 2008

The Windows Presentation Foundation ("Avalon") forum seems a better place for this question to get an answer, moving from Visual C# General.

Re: Windows Presentation Foundation (WPF) How to get the screen resolution in wpf

LesterLobo - MSFT

the size you see on screen would change because you are changing the screen resolution. However, querying the control size should return the same value as before
