<listview item value = "Alex" text="alex" />

where is the text property of the listview item... so many changes

What would be my best bet? Azure or something else? And if Azure what part of Azure would I use?

Thanks in advance.

I am working on  a program to allow users to draw objects on a screen. It needs to do this through code, not XAML. I have a class inheriting Canvas that implements protected functions like, AddVisualChild, AddLogicalChild, RemoveVisualChild, RemoveLogicalChild. These methods can only be accessed by an inheriting class - if I use the Canvas object instead of the subclass, these methods cannot be accessed. My class will draw lines, curves and other Visuals. But I want to also add a TextBox into which the user can type directly, which I haven't been able to do. If I create an instance of TextBox and add it the children of the my subclass, the textbox does not appear. I've verified that it's there in debug mode and using Snoop. Is there a property I need to set. Setting Visibility and ZIndex do nothing.

If i create a Canvas (not an instance of my DrawingCanvas class) in XAML and put a TextBox under it, it appears fine. But if I try to add a Visual in code to the Canvas using

theCanvas.Children.Add(myVisual)

theCanvas.Children.Add(myTextBox)

Anyway, everything works well except... I' can't figure out how to disconnect from the client side. Specifically, I'm following the pattern where the server/client shares a common interface declaration, and there is no shared DLL. However on the client side, I have a reference to the interface, but since it isn't derived from MarshalByRefObject, I can't figure out how to initiate a clean disconnect from the client side.

On the client, I'm doing this:

var channel = new TcpClientChannel();
var url = "tcp://" + ipAddress.ToString() + ":" + port.ToString() + "/MyService";

ChannelServices.RegisterChannel(channel, false);

var remoteApi = (IMyInterface)Activator.GetObject(typeof(IMyInterface), url);

Anyone have an idea?

I am a developer with no prior knowledge or experience with blend and I am having a really hard time trying to utilize it with my app. I am making a game in windows 8 and so far everything works but I am having a hard time with the game animations that I am creating in blend. 

What I am making is box that will have images fly out of it while the user tries to click on each image to transform it to something else. So far I have the code to transform the image which is this:

Image1.Visibility = Visibility.Visible;
Image2.Visibility = Visibility.Collapsed;

And in blend I can make the animation to make the images fly up but how would I go about making a ton of them come from below the frame of the page -> out of the box -> into the air so the user can hit them to transform?

Any help would be great guys!

I tried to do this once with reflection but I couldn't figure out how to do it.

I have few queries on Windows Phone 8 + ETW logging as Windows phone 8 is built makes use of NT kernel, I am expecting the ETW logging feature also must be available. Is that true? If so is there any application that can act as controller? like xperf.exe? Also how do I get list of available/supported providers on Windows phone 8?

Thanks

I am implementing a windows service. The service handles PRESHUTDOWN notification from service control manager. Notification is being received while the device goes to shutdown. Now I need to access a particular driver on receiving the this notification. 

I am using CreateFile() API to get handle to the driver and send an IOCTL using the handle. But I am getting an error from CreateFile() (error code 2;parameter invalid). But same procedure works when I move the driver access code to a stand alone application.

Is there a limitation that services cannot access driver with CreateFile? (http://stackoverflow.com/questions/8263380/send-ioctl-to-windows-device-driver-createfile-fails)

How this can be avoided? 

Thanks

<Style x:Key="ColorPickerStyle" TargetType="ListBox">

            </Setter.Value>
        </Setter>
</Style>

I love the way it looks, but the last I'd like to do is change how the selected color looks. All I want to do is remove the selected item color and make the selected item's rectangle have a StrokeThickness of 2. I tried to do this with triggers, but they don't seem to exist in WSA XAML. I tried to do it with the VisualStateManager, but I somehow kept messing up the XAML so that it crashes when I run.

Can someone help me through this before I lose my freakin' mind?

This is what I want to do now:

Server:

• Define an interface and add ServiceContract, OperationContract, etc attributes.

Client:

• Be able to consume the interface defined by the server without requiring a shared DLL or XML config file at runtime.

Now the server and client are both projects within the same solution, and will never be compiled separately, but will run on different systems. So it is possible to share the same source files between the two projects (maybe that's all I need?). What I am looking for is to end up with both the server and client having a single *.exe file and not require a shared DLL or config file.

Is this possible with WCF?

                    <VisualBrush>
                        <VisualBrush.Visual>
                            <Canvas>
                                <Line Stroke="Black" X1="0" Y1="0"
                                      X2="100" Y2="0"/>
                                <Line Stroke="Blue" X1="0" Y1="0"
                                      X2="100" Y2="0" Canvas.Left="10"/>
                            </Canvas>
                        </VisualBrush.Visual>
                    </VisualBrush>

Is there an easy way to do this? The line will be rotated and resized. I've gotten ideas about using a rectangle with no fill and colored stroke, but the rectangle's orientation stays fixed as you rotate the line.

(In case this at all matters, I'm trying to change the line stroke for Telerik diagram connections)

I am working on a project in VS2012 that should be compatbile with Windows XP.

this is the code by alexkai

Protected Overrides Sub Dispose(ByVal disposing As Boolean)
    Try
        If disposing Then DisposeShapeContainer(ShapeContainer1)
        If disposing AndAlso components IsNot Nothing Then
            components.Dispose()
        End If
    Finally
        MyBase.Dispose(disposing)
    End Try
End Sub
Protected Sub DisposeShapeContainer(ByVal AShapeContainer As Microsoft.VisualBasic.PowerPacks.ShapeContainer)
    If AShapeContainer IsNot Nothing Then
        If AShapeContainer.Shapes IsNot Nothing Then
            Dim tshapes As New Generic.List(Of Microsoft.VisualBasic.PowerPacks.Shape)
            For Each tshape As Microsoft.VisualBasic.PowerPacks.Shape In AShapeContainer.Shapes
                tshapes.Add(tshape)
            Next
            AShapeContainer.Shapes.Clear()
            AShapeContainer.Shapes.Dispose()
            For Each tshape As Microsoft.VisualBasic.PowerPacks.Shape In tshapes
                tshape.Dispose()
            Next
        End If
        AShapeContainer.Dispose()
    End If
End Sub

this method is called by Form.Close, and it runs fine.
after Form.Close is called by Form.Dispose and the method starts again, this generates an exception "Object reference not set to instance of an object" because it has been previously destroyed by Form.Close.

To avoid this thing, my solution, maybe not one of the brightest, was to modify two lines of the method.
The first, changing ByVal to ByRef (directly to refer to the object concerned and not to a copy)

Protected Sub DisposeShapeContainer(ByRef AShapeContainer As Microsoft.VisualBasic.PowerPacks.ShapeContainer)

and I added this at the end, after AShapeContainer.Dispose()

AShapeContainer = nothing

to mark the current object as Nothing, to exit from this is if the Object is set to Nothing

If AShapeContainer IsNot Nothing Then

If someone has a better solution would be nice to be able to show! I'm working on something more refined I will publish when ready.

I'm sorry for my not "perfect" English.

The viewmodel receives a message (via the MVVMLight Messenger classes) that a bitmap needs to be saved, and in order to do that, it needs a reference to the visual. Which means a reference to the view, which ties my viewmodel to my specific view, which I don't want.

Another idea would be to have the view render the bitmap and expose it to the view in some way via a OneWayToSource binding, but I have no idea how to tell it when to update via the viewmodel.

Anyone got any ideas?

The default D3D native template has cube renderer sample. Are there any samples to show simple text "Hello World" in D3D template instead of rendering cube? Other word how can I display text in D3D application?

Thanks

• I've created an API area which provides Products, Categories lists as json; it contains two controllers ProductController and CategoryController.
• On the client side I'm using Backbone.js and Home->Index.cshtml view as main application page. 
• Also I've created Admin area which also contains two controllers (ProductController and CategoryController).

I can't decide how do I implement Admin area. I've been thinking about implementing just one entry point where administrator accesses lists of products, categories, orders etc. and edits them. 

But! url areas/admin/home/index looks wierd. home/index segment sounds meaningless. 

Should I split Admin area by adding a controller per entity? Or is it better to have no areas at all and to have admin controller with authorization attribute applied?

Need an advice. How is that implemented in real world projects?

This is just a small question I couldn't really find an answer on.
In Windows Store apps, you can access the Temporary folder of your app and you can store files there. But when is this folder cleared? Or does this never happen?

Thanks in advance,

Thanks.

I was just watching the C9 lecture from Stephan about STL algorithms and functors, and I can't really wrap my head around std::equal!

I mean, for me the semantics is a bit strange, since what it does is IMHO more like "isPrefixOf(...)" than an equality check. What was the idea behind implementing std::equal as it is? Is the functionname "equal" not a bit misleading for what it really does?

However, when you run the application, a runtime exception is thrown because the ThirdLibrary assembly can't be find. To remedy this, you need to manually add a reference to ThirdLibrary in the Application assembly as well. Why can't the compiler figure this out for itself?

I want to launch my application soon after tiled screen appear? How to do it? Are there any boot notifications based on which we can do this?

Thanks

var list = new List<KeyValuePair<string, decimal>>();

I'm pretty sure C++11 had something like this, why doesn't C# have it?

There is a constraint in Couchbase .NET client for models to expose a class-name property. As it is reflected in their documentation it can be resolved by using this code:

class abstract BaseModel {
    public abstract String Type {get;}
}

class Robot : BaseModel {
    public override String Type {
        get { return "Robot"; }
    }
}

Is it possible to automate this from within the BaseModel class?
