    - data bound TextBox doesn't send it's value to object's property when button in toolbar is pressed By default, TextBoxes do not update source until the LostFocus event. Otherwise the source would update on each change. You have two options...you could change the UpdateSourceTrigger on your binding to PropertyChanged (which can cause validation errors if you are doing validation). Or you can of course call UpdateSource explicitly on the BindingExpression when you hit save. For more info see this msdn article .

    - Feature request for C# 3.0: Type inference for class variables It's all done compile time; there'd be no trouble having a much stronger inferrence system than C# currently has. My wish is that the C# compiler would infer in pretty much every case it is possible to do so. But anyways a conflict between Dictionary and Dictionary -- it'll complain that you have both namespaces (Generic and other) imported into the file. Since that isnt commonly the case, no big deal. However, you do bring up another shortcoming of C#'s type inference/generics: no easy way to specify a type wildcard. For example, to disambiguate the two dictionaries, you should be able to do something like : Code Snippet var x = new Dictionary<_,_> {...} or perhaps var x = new Dictionary<,> {...} These wildcards would come in handy in other places where the C# compiler inferrence shows its weakness. For instance, suppose you call a function that allows you to specify the return type: Code Snippet int GetSomeInt() { return Foo("foo"); } This is silly: both string AND int _could_ be inferred. But for some reason, C# won't do the work and forces us to annotate. Well, if they are going to decide not to infer, then the least they can do is allow us to annotate as little as possible. The callsite above could be: Code Snippet return Foo<_, int>("foo"); This might sound like we're just picking on having to type a bit more here and there, but if you write some heavily generic code, it certainly is nice to have strong inference. It's not like you're losing anything: The compiler and IDE still know all the type information of course. -Michael Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - Unidentified channel call Hello, if I return null or false at the first call the dispatcher doesn't process the message (the first message that I want to receive). After receiving and sending back the response, the wcf goes again to BeginTryReceive, and the loop starts. If I don't receive any bytes in the next messages I return a null message and false as the result value of the EndReceive method, but the loop still continues. Another thing I see, is that after closing the channel (when I do the send) the state is 'closed' but it calls BeginTryReceive again. In the documentation says that a closed ICommunicationObject cannot receive messages... So what's happen Could I try anything else to solve this problem Regards, Markus Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - Setting SelectedItem of ComboBox bound to an Enum Hi, I've reserved some time to take a look at your question. You don't need to do conversion, because it's possible to define the type in your settings file. I've also done some testing to verify correct operation. If you change the default type "string" to "[your namespace].ImageSize" for the ImageSize entry in your settings file, it should work.

    - Creating an AppBar in WPF To accomplish that, you can start by creating a Window object and set its desired size and location based on the current screen resolution. The property you want to set to ensure it doesn't get hidden behind other windows is Topmost =true. You might also want to turn off the default WindowStyle =None so it take out the system buttons (max/min/close) and Window ResizeMode =NoResize, so you can control the resize behavior programmatically. Hope this helps to get you started. Thanks. Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - Linq, Iquerable and anonymous types A better solution is usually to try and cast the result set to a specific type. If it works out that you can map to an existing entity type use that, otherwise you can manually create a result type and set the result to IQueryable<yourCustomType>. Using Reflection works but as you know it can be very slow in iterative situations. Note that that if you're using databinding operations especially in ASP.NET that object binding uses Reflection internally anyway so you can use var results passed out of a calling method as a datasource. Another option is that you can cast the var result to something else if you choose. You can 'cast' DataReader or DataTable with just a little work running the command object associated with the query object. In some situations this may actually provide much better performance (especially in databinding situations) although it does work against some of the very concepts that make LINQ so enticing in the first place. +++ Rick --- Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - User controls from external dll in toolbox Thanks, that got me one step closer - but I'm still having trouble getting it to recognize my user control. Sorry, very basic stuff, but I'm having a hard time finding appropriate reference material. The samples I've found with external control libraries use .cs files, but I'd like to use .xaml user controls. Is there something I should add to the control's declaration Right now the user control file is named GuiBox.xaml and its "header" is simply: < UserControl x:Class = " OpenBlackBox.GUI.WPF.GuiBox " ... And the referring code: ... xmlns:ObbGui = " clr-namespace:OpenBlackBox.GUI.WPF;assembly=OpenBlackBox.GUI.WPF.dll " ... <ObbGui:GuiBox /> ... But the tag is not recognized (I've tried many different variations for defining the tag, but this seems most natural to me) One problem is that the compiler doesn't seem to warn if the dll can't be found, so maybe that's the cause here. However, it's referenced in the project so it should be available. Thanks for any further help! Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - Bare parameter style There is no way to do this within the programming model without using MessageContract, and yes, the programming model for MessageContract is inconvenient in that it introduces an extra class for each message. You can work around it by doing minor imperative surgery on the description, as in the sample code below. (Try toggling the value of BARE and see the effects.) //#define BARE using System; using System.ServiceModel; using System.ServiceModel.Description; using System.ServiceModel.Dispatcher; using System.ServiceModel.Channels; class MyDMI : IDispatchMessageInspector { public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext) { Console.WriteLine(request.ToString()); return null; } public void BeforeSendReply(ref Message reply, object correlationState) { } } class MyEB : IEndpointBehavior { public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters) { } public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime) { } public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new MyDMI()); } public void Validate(ServiceEndpoint endpoint) { } } [ServiceContract] public interface IMyContract { [OperationContract] string echo(string s); } public class MyService : IMyContract { public string echo(string s) { return s; } } public class Repro { public static void Main() { Uri address = new Uri(" http://localhost:8004/Service "); Binding binding = new BasicHttpBinding(); ServiceHost service = new ServiceHost(typeof(MyService), address); ServiceEndpoint e = service.AddServiceEndpoint(typeof(IMyContract), binding, address); e.Behaviors.Add(new MyEB()); MakeBare(e); service.Open(); ChannelFactory<IMyContract> cf = new ChannelFactory<IMyContract>(binding, new EndpointAddress(address)); MakeBare(cf.Endpoint); IMyContract proxy = cf.CreateChannel(); Console.WriteLine(proxy.echo("Hello World")); ((IClientChannel)proxy).Close(); service.Close(); Console.WriteLine("Done, press a key"); Console.ReadKey(); } static void MakeBare(ServiceEndpoint e) { #if BARE MessageDescription md = e.Contract.Operations[0].Messages[0]; md.Body.WrapperName = null; #endif } } Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - INotifyPropertyChanged Ok, I see what you're trying to do now. So the problem is, overriding OnPropertyChanged is not how you catch the changing of properties on other controls as changes don't magically propagate up the hierarchy. Property changes must be caught by hooking the PropertyChanged event of the instance of each control. Let me see if I understand what you're trying to do, you want to know when a certain property of any child of your custom canvas changes and, in response to that, do some kind of processing. Is that correct Theoretically you could continue doing what you're doing with implementing INotifyPropertyChanged, then as children are added to your Canvas you hook their change notification and see if it's the event you're interested in, but it's going to create a lot of overhead and isn't really the "right" approach in the WPF control world. Do me a favor and confirm that I understand what you're trying to do and fill in more details if possible and then I can try and suggest a good approach for it.

    - Redundant Dependency Properties tasosval is correct in that the parser won't call your public property if it can access the DP directly. Yes, we frown upon chaining DPs together because it can lead to really bizzare results and very hard to debug situations. One issue is a DP can get its value from many sources and there is a precedence order to them. Say you're animating the X DP which then updating Position. If you then go and manually change Position while the animation to X is still going on, I believe X will keep animating and have precedence over the value you just gave to Position. When X updates again, your local Position value will be overwritten. The recommended way to chain DPs together is to use data binding. You could databind X and Y to Position.X and Position.Y but then you lose the ability to set X/Y because setting them would drop the data bind. It depends on what your usage scenario is, but you could just make X and Y be the DPs and have Position not be but pull its values from X and Y.

    - .NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506) I get the Fatal Execution Engine Error too, exactly as shown in the subject. It happens when my console client calls the single method on my new WCF web service (hosted as an IIS app). I read the KB article 913384 and it was all nearly identical to the symptoms I'm seeing, except that I don't really understand what it means by "runs under a user account context". I've tried both the wsHTTPBinding and the BasicHTTPBinding, and I'm not sure if either of them runs under a user account context. I installed the fix from the KB article, and rebooted. The exact same error occurs, except that the .NET Runtime version is now 2.0.50727.63. The web service responds without problems when I browse to the Service.svc URL, and also works fine when I browse to the Service.svc wsdl URL. The problem only occurs when I invoke the Operation (method) from my client app. I've spent a full day on this so far. If you have any ideas, I would appreciate hearing about them. Thanks!

    - closing servicehost hosted in windows service Hi all. I have WCF hosted in windows service. If I try to close in "OnStop" of servicebase class it will forcefully kill threads running services. Typically servicehost.close() for my application will take few minutes. I believe SCM (Service Control Manager) will interrupt servicehost.close() if it is taking too long. My questions are 1. Is there anyway I can access servicehost directly so that I can just call close() which will graciously wait for all threads to complete (Increasing timeout for SCM is good way ) 2. OnPuase or OnCustomCommand will act differently 3. I can get servicehost from service instance using "operationContext" but if I issue close() there it will be deadlock case, isn't it servicehost --> service instance --> servicehost.close() Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

    - where have my netMsmqBinding messages gone? Check the destination queue properties; if it is a transactional queue and you sent it non-transactional messages, they would go in the transactional DLQ. -James Tag: LINQ Project General Issues with Linq in VS2005 SP1 Visual Studio 2008

I've just installed the may linq download, but I have an issue trying to use it.

The IDE picks everything up OK, intellisense works fine.

But when I try to comile I get errors all over the place, except for in downloaded examples where I use the project file for the download.

I've figured out where the issue lies:

The above had to be included in the csproj file for the compiler to work, what I can't figure out is why, or how to get the imports into the project file without manually hacking it in there.

Sorry is these are dumb Q's :)

TIA,

Stu

The line you mention replaces the compilers by the new ones, which is required for LINQ support.
You have to add it manually for existing projects, but for new projects you can use the provided project templates for Visual Studio 2005. See the "Visual C# / LINQ Preview" or "Visual Basic / LINQ" folders in the "New Project" dialog.
