    - C# Express Orcas does not detect changes to XAML files. When I click "Run" (Start without debugging) after making changes to a XAML file through the XAML text editor, VS does not detect the changes and runs the application without first rebuilding it. I have to click "Build" before clicking "Run" for the changes to take effect. This only happens with the XAML text editor. Changes made using the C# text editor are detected and do not require me to explicitly click the "Build" button.

    - Force ClearType over Grayscale Antialiasing Anti aliasing small text tends to make the letters look blurry and indistinct. I cannot find a way to disable the anti-aliasing of text in WPF and as a result label or button text looks really bad. Ideally I'd like to disable anti aliasing globally for font sizes below a certain size.

    - how to create a message from scracth? Hello, I'm writing a MessageEncoder because I'm receiving a non-standard stream and I want to create a message from it's values, so: 1) I 'understand' the parameters of the operation from the stream and use a DataContractSerializer to serialize them to the body of the message... The question is: How do I correctly write the body of the message Because I can write a parameter using the DCS but I can't write the Operation Name, so the dispatcher fails when it tries to resolve the call: OperationFormatter encountered an invalid Message body. Expected to find node type 'Element' with name '[ OperationContract_Name ] ' and namespace '[ ServiceContract_Namespace ]'. Found node type 'Element' with name '[ DataContract_Name ]' and namespace '[ DataContract_Namespace ]' This is: I'm sending the parameter of the operation contract that I want to call, but I don't write the first element with the operation contract name... So, how can I do that Thanks, M Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard. Visual Studio 2008

    - Position the bullet of a RadioButton Hello, I'm desperately searching for a way to change the position of the bullet. Actually I only need to change the alignment of the bullet when the content of the RadioButton grows. I already created a custom Template for the RadioButton but either I'm blind or just plain stupid since I can't find a way to change this. The Bullet is always vertical centered - I would like to have it on the top. Any ideas Any samples where the look of a RadioButton was altered completely Thanks, quilty Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard.

    - Unusual ReleaseMouseCapture behavior Here's what I am trying to do. I have a PreviewImage window (Window derived) that's popped up when a button is clicked. It's popped up using Show() as a non-modal window. I want it to close when the user clicks anywhere outside the window [so it behaves like a tooltip window - I cannot use the tooltip window due to various reasons]. Here's the basic code :- Code Snippet public PreviewImage() { InitializeComponent(); Loaded += new RoutedEventHandler(PreviewImage_Loaded); MouseUp += new MouseButtonEventHandler(PreviewImage_MouseUp); } void PreviewImage_MouseUp(object sender, MouseButtonEventArgs e) { ReleaseMouseCapture(); <-- this fails if (!IsMouseCaptured) { Close(); <-- this never hits } } void PreviewImage_Loaded(object sender, RoutedEventArgs e) { CaptureMouse(); } For some reason, the call to ReleaseCapture does not succeed. Does anyone know why this would be happening Thanks in advance. Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard. Visual Studio 2008

    - svcutil occasionally failing with shared generic model? I have a strange problem: I am currently developing a WCF-based application, where the model is shared between client and serviceimplementation, and I keep getting errors now and then when using svcutil.exe I have a model class (a query object used for some fancy datafetching): //[DataContract(Name="QFieldBinaryOf{0}")] [ DataContract ] public abstract class QFieldBinary <TFieldType> : QBinary < QField , QValue <TFieldType>> { public QFieldBinary() { } protected QFieldBinary( string fieldName, QValue <TFieldType> fieldValue) : this ( new QField (fieldName), fieldValue) { } protected QFieldBinary( QField field, QValue <TFieldType> fieldValue) : base (field, fieldValue) { } } which inherits from: [ DataContract ] public abstract class QBinary <TLeft, TRight> : IQueryElement { public QBinary() { } protected QBinary(TLeft left, TRight right) { this .left = left; this .right = right; } private TLeft left; [ DataMember ] public TLeft Left { get { return this .left; } set { this .left = value ; } } private TRight right; [ DataMember ] public TRight Right { get { return this .right; } set { this .right = value ; } } } That's pretty straight forward: A generic class inheriting from a generic baseclass. When I try to generate client proxies for this with svcutil, I sometimes get and error saying the the referenced type does not match the imported datacontract. If I then try to uncomment the top attribute on QFieldBinary and comment the other out, it seems to work. However sometimes it is the other way around: The bottom attribute works but not the top. the command, I run is: svcutil http://localhost:49690/Private/PersonListService.svc wsdl /config ervices.config /namespace:*,Bestseller.BestHuman.WebClient.ServiceAccess /r:"C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll" /r:"C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll" /r:"..\bin\debug\Bestseller.BestHuman.Model.dll" I have tried with different serializers, but none seems to be working. It seems very strange to me, that I only get the error some times - and that it works perfectly other times..

Because of the absense of a way to communicate through javascript with the application, we do use a webservice to pass data to our application using a pull mechanism, this works, but is not optimal.

    - How to use CaptureMouse method I have a Canvas in which I have added some entities and when I selected one entity and moving my mouse entity should move with it. I have implemented it but when I am moving my mouse very fast it leaves the entity. Overall, moment of the entity is not very smooth. That's why I have tried to use CaptureMouse() method. When I am selecting an entity, I call the Mouse.Capture(<entity name>). But it then it stops moving. Nothing is happening, entity movement get stopped. I have also added Mouse.Capture(null) in the MouseUp event. Or is there any other way of making the movement of the entity smooth. Please let me know if further clarification is required.

    - Problem with adaptive context menus I have a context menu with menu items. Some of the menu items have children (i.e. subgroups). The context menu is adapting it's content depending on what I right-click. This is accomplished because I have attached a command to each menu item that isn't a group, and these items become disabled when the command can't run. Since I does't want disabled items in a context menu, I have a style making all disabled menu items take the visibility property "Collapsed", making them disappear when they become disabled. The problem now is how do I hide menu item groups when all their children are collapsed Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard. Visual Studio 2008

    - WCF - Upload a file to a service with a progress bar in the client Hi all, I'm currently experimenting WCF, i'm pretty new to this whole thing actually. I'm using VB.NET (VS2005). So here's the thing: I'm building a small test application using WCF to upload a file to a service. I created 2 ways of uploading my file, both work perfectly. I can send the file in chunks or stream it. I tried to add a progress bar so I could see the progress on the client side. Works perfect with the chunk upload, but I can't seem to get it to work with streaming. I tried using a callback, but it seems that I won't receive any callback before the whole process is done. I do know that's normal since I didnt use "IsOneWay:=True"but I do not want to use this attribute because I don't want the process to continue before the file is totally uploaded. Is there any way to send some feedback from my service to my client to monitor progress Here are parts of my code: Service <ServiceContract(CallbackContract:= GetType (IServiceUploadFichierCallBack), SessionMode:=SessionMode.Required)> _ Public Interface IServiceUploadFichier <OperationContract()> Sub UploaderFichierStream( ByVal pfStream As Stream) End Interface Public Interface IServiceUploadFichierCallBack <OperationContract(IsOneWay:= True )> Sub MAJFloodStream( ByVal pintStream As Integer ) End Interface Upload function Public Sub UploaderFichierStream( ByVal pfStream As System.IO.Stream) Implements IServiceUploadFichier.UploaderFichierStream Dim outstream As FileStream = File.Open(mstrDestination, FileMode.Create, FileAccess.Write) Dim content() As Byte ReDim content(0) Const bufferLen As Integer = 4096 Dim buffer(bufferLen) As Byte Dim count As Integer = 0 Callback = OperationContext.Current.GetCallbackChannel( Of IServiceUploadFichierCallBack)() count = pfStream.Read(buffer, 0, bufferLen) While (count > 0) Try Console.Write( "." ) outstream.Write(buffer, 0, count) Callback.MAJFloodStream(count) count = pfStream.Read(buffer, 0, bufferLen) Catch ex As Exception Call MsgBox(ex.Message) End Try End While outstream.Close() pfStream.Close() End Sub This is what I use on the client side: Public Class CallbackHandler Implements ServiceUploadFichier.IServiceUploadFichierCallback Public Sub MAJFloodStream( ByVal pintStream As Integer ) Implements ServiceUploadFichier.IServiceUploadFichierCallback.MAJFloodStream Form1.ProgressBar2.Value = Form1.ProgressBar2.Value + pintStream End Sub End Class Private Sub cmdShareStream_Click_1( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdShareStream.Click Dim Callback As InstanceContext = New InstanceContext( New CallbackHandler) Dim service As New ServiceUploadFichier.ServiceUploadFichierClient(Callback) Dim infoFichier As New ServiceUploadFichier.MessageInfoFichier Dim fstream As FileStream = New FileStream(txtSource.Text, FileMode.Open) Dim dblAvant As Double Dim dblApres As Double service.Open() Try dblAvant = Timer infoFichier.Destination = txtDestination.Text service.InitialiserFichier( "" , "" , infoFichier.Destination) ProgressBar2.Value = 0 ProgressBar2.Maximum = fstream.Length service.UploaderFichierStream(fstream) dblApres = Timer lblTempsStream.Text = (dblApres - dblAvant).ToString( "0.00" ) Call MsgBox( "Source: " & txtDestination.Text & vbCrLf & "Destination: " & txtAdresseSharepoint.Text) Catch ex As Exception Call MsgBox(ex.Message) End Try fstream.Close() service.Close() End Sub I think I posted the most important parts, don't hesitate to ask I more is needed to find the problem Thanks in advance, Fred Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard.

    - Customizing a ComboBox's SelectionBoxItem when SelectedItem=null I have a combobox whereby I want it ("them", really, as I've got several) to display some grayed-out, italicized text in the combo box if there is no selection (i.e. the app just started), but to show the normal item when one is selected (IE7's search dropdown does this). The catch is that I can't set ComboBox.Text to the value because IsEditable=false, so that value's ignored. I've tried messing with the ItemTemplate, but that doesn't apply to the selected item. The only solution I've found is to manually create the entire combobox's style, but in doing so, I tie that behavior to a particular look (for example, I'd have to hardcode the "Classic" theme (or "Aero" or "Luna") with the display bevavior). It seems like this kind of styling should be pretty easy, but I'm not seeing an easy solution, but I really, really, really do not want to rebuild an entire combobox look just to get the desired behavior.

    - SQLMetal / visual editor - connecting to remote server I’m unable to find any examples for sqlmetal where it connects to a remote SQL 2k5 server over TCP/IP. What is the syntax for the ”/server:” option for this work Also, what rights are required for the sqlmetal/visual editor to work Currently I have a SQL 2k5 database where the user is mapped to the ”db_datareader”, ”db_datawriter” and ”public” roles. But the visual editor doesn’t work with this. If I add the user to the ”sysadmin” role on the SQL 2k5 server, it works. But this is not a solution for me. So what tables and accessrights are required for the SQLmetal/visual editor to work On the same note, what rights are required for the runtime to work. When we deploy this to a production server, I would like to lockdown the user, and if fewer rights are needed for runtime, than for sqlmetal/visual editor I would like to know about this also. I have searched the forums, documentation and google for answers to these quetions, but without luck, so I would appreciate any help. best regards Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard.

    - Softness of text and art in WPF apps, designed in Blend I have a question regarding a softness or blurriness of text and art (bitmap and vector) brought into Blend. Is there a way to turn this off, so that the UI is as sharp as a non-WFP application With text, this is apparent even in the Blend UI itself. The Blend menus and labels are not as sharp as comparable elements in other Windows applications. Designing your typical application, with inevitable tiny text here and there, is very difficult as the text becomes blurry when working with Blend, where it does not degrade the same way in a web page or old style of client application. This is especially problematic to implement a Photoshop design (using small text set with anti-aliasing of 'none' or 'sharp') and having it be readable in Blend. Graphics have a similar issue. Creating a button in Design and bringing it over to Blend results in a perceptible loss of crispness. Bringing over .png elements (for small widgets and buttons) from Photoshop have even more pronounced blurring. In both Design and Photoshop the elements are created at 96 PPI. So, is there a way to sharpen the display of text and graphic elements when designing with Blend Are there some tags I should be adding or removing from the xaml Thanks in advance, Derek Tag: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard.

Neither of these work in my static method, any ideas

Code Snippet

Storyboard loadAnimation = (Storyboard)Application.Current.FindResource("OnUnloaded1");

//where loadAnimation_Completed is a static event handler

loadAnimation.Completed += new EventHandler(loadAnimation_Completed);

//this fails the same way

loadAnimation.Completed += delegate

{

//do something

};

The error I get is:

"Specified value of type 'System.Windows.Media.Animation.Storyboard' must have IsFrozen set to false to modify."

How can I get a non-frozen instance of my storyboard so I can modify it in my code

TIA,

Re: Windows Presentation Foundation (WPF) Can't get a non-frozen instance of my storyboard.

Figured it out. The solution is to use a cloned instance of my storyboard:

Storyboard animation = (Storyboard)this.FindResource("OnUnloaded1");

loadAnimation = animation.Clone();
