Not really - knowing the security sandbox Silverlight runs in - I would feel this would not be possible.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

No you can't. If the manufacturer provided a COM API, you could accomplish this through the COM OOB experience.

I figured...

You know, I had really expected this to be allowed in SOME manner since this provides a pretty reliable way to authenticate. I would have almost expected that a BIO API device would be allowed. Geeez, they allow you access to the camera and headset while remaining in-browser now, why not a security device Smile | :)

The theory is that by this stage you will already have been authenticated.

Hi guys,

I have go get all names of columns of all tables in the model???How can i do this??

i'm a beginner of programming in silverlight

You need a web service to do this - you cannot directly use ado.net in Silverlight.

Ok..can u plz give me more details?

anyway , thank u very much

*** i have chaged my ID from dchamba to jadughar

On the WCF side, use ADO.net to get the column names. Return this as a list to Silverlight via the service.
That should do it.

Thanks Abhinav thank you very much

Hi abhinav your answer was good.

but what did you mean with "use ADO.net to get the column names"???

thanks

You will need to write a query and execute it(probably using a data adapter) to fetch the column list on the server. You will then pass this back to the client via the WCF service.

Hi Abhinav I would like to thank you for your patience with me.

You'll now understand that i am a beginner, and i'm not very good to talk in english.

Do you have some article or tutorial, about creating a Service, which explain the topic easily???

You could start with this[^].

MSDN will[^] always be your best friend.

Hello

I want to display hierarchical data in Silverlight 4. E.g. Invoices at the top and Invoice Lines under each invoice header. How can I do that?

Regards,

Try

Hierarchical Data Templates in Silverlight[^].

Telerik provides a hierarcial datagrid - http://www.telerik.com/help/silverlight/hierarchical-data.html[^].
So does Infragistics.

I don't want to pay for it. I am sure I can do it without paying for a third party control.

Use a ListBox with DataTemplates - show the invoices in the ListBox then in the datatemplate for the invoice have another listbox showing invoice lines (again use a datatemplate) - if you wrap each invoice in an expander and do some styling you can make it look very funky indeed.

I am sure this something really simple and I have been looking at it for too long but why doesn't this show anything?

   public partial class Window1 : Window
    {
        public XmlDataProvider Provider { get; set; }

        public Window1()
        {
            InitializeComponent();

            Provider = new XmlDataProvider();
            Provider.Document = new XmlDocument();
            Provider.Document.LoadXml(TestXml.Test.Test());
            Provider.XPath = "Halloumi";
        }
    }


<Window x:Class="HalloumiDesigner.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300"
    DataContext="{Binding RelativeSource={RelativeSource Self}}">
    
    <Window.Resources>
        
        <HierarchicalDataTemplate DataType="Database" ItemsSource="{Binding XPath=Databases/Database}">
            <Border BorderBrush="SteelBlue"
                    BorderThickness="2"
                    Background="AliceBlue">
                <TextBlock Text="{Binding XPath=@Name}" />
            </Border>
        </HierarchicalDataTemplate>

    </Window.Resources>
    
    <Grid>
        <TreeView Name="TreeView" ItemsSource="{Binding Provider}" Margin="10" />
    </Grid>
</Window>

XML is:

<Halloumi>
                   <Databases>
                       <Database Name="A"/>
                       <Database Name="B"/>
                   </Databases>
               </Halloumi>

Nobody?

Your treeview needs to be bound to an ObservableCollection

Everything makes sense in someone's mind

It doesn't but thanks for answering. I have abandoned the TreeView and gone for a ListBox and Data Templates - far better.

Hi ,
i wish build a control(wpf) that the Eye(Ellipse) follow the cursor of the mouse.
here is a snippet code that i am developing :

XML

<Window Height="480" Title="Window2" Width="640" x:Class="WpfApplication5.Window2"
     x:Name="Window" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Window.Resources>
<Storyboard x:Key="OnLoaded1">
<DoubleAnimationUsingKeyFrames Storyboard.TargetName="ctrCircle" 
    Storyboard.TargetProperty="(UIElement.RenderTransform).( TransformGroup.Children)[3].(TranslateTransform.X)">
<EasingDoubleKeyFrame KeyTime="0:0:0.8" Value="1">
<EasingDoubleKeyFrame.EasingFunction>
<ExponentialEase EasingMode="EaseOut" />
</EasingDoubleKeyFrame.EasingFunction>
</EasingDoubleKeyFrame>
        </DoubleAnimationUsingKeyFrames>
        <DoubleAnimationUsingKeyFrames Storyboard.TargetName="ctrCircle" 
            Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)">
                <EasingDoubleKeyFrame KeyTime="0:0:0.8" Value="1">
                    <EasingDoubleKeyFrame.EasingFunction>
                        <ExponentialEase EasingMode="EaseOut" />
                    </EasingDoubleKeyFrame.EasingFunction>
                </EasingDoubleKeyFrame>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
        <Style TargetType="Ellipse">
       <Setter Property="RenderTransform">
            <Setter.Value>
                <ScaleTransform ScaleX="1" ScaleY="1"/>
           </Setter.Value>
        </Setter>
       <Setter Property="RenderTransformOrigin" Value="0.5,0.5"/>
    </Style>
    </Window.Resources>
 <Canvas MouseMove="mov" x:Name="LayoutRoot">
    <Border ackground="Black" B="" Canvas.Left="178" Canvas.Top="103" 
        CornerRadius="250" Height="255.5" Width="290" x:Name="border_eye">
        <Ellipse Fill="#FFFFC600" Height="12" HorizontalAlignment="Left" 
            Margin="0" RenderTransformOrigin="0.5,0.5" Stroke="{x:Null}" 
            VerticalAlignment="Center" Visibility="Visible" Width="12" x:Name="ctrCircle">
            <Ellipse.RenderTransform>
                <TransformGroup>
                     <ScaleTransform />
                    <SkewTransform />
                    <RotateTransform />
                    <TranslateTransform />                 
                </TransformGroup>
            </Ellipse.RenderTransform>
        </Ellipse>
    </Border>
</Canvas>
</Window>

and in the code behind :

C#

private void mov(object sender, MouseEventArgs e)
        {
	 System.Windows.Point pt = e.GetPosition((Canvas)sender);
          Storyboard invokeStoryboard = this.Resources["OnLoaded1"] as Storyboard;
            ((DoubleAnimationUsingKeyFrames)invokeStoryboard.Children[0]).KeyFrames[0].Value = pt.X;
            ((DoubleAnimationUsingKeyFrames)invokeStoryboard.Children[1]).KeyFrames[0].Value = pt.Y;
            invokeStoryboard.Begin();
        }

now my purpose is when i move the mouse in the Canvas area(LayoutRoot) the Ellipse(ctrCircle) move only inside the Border(border_eye) and don't overcome the area of the "border_eye" this effect is similar an eye.

Do you have any idea how to perform this step?

Thanks so much for your attention Smile | :)

Have a nice day.

Nearly all, no ALL the upload demos place the uploaded files in the folder of the web service, or a sub folder.

I am building a site that has 2 distinct web sites, Admin and User sites, admin uploads the files and user consumes them. I would like to use the separate WCF to write to the server file system but keep running into permission issues. This will be exacerbated when I want a common folder for the uploads that is a peer of the root folders. Something like

AdminWeb
PublicWeb
Uploads
Documents
Images

OR

To make it simpler should I just stick admin and uploads under the user web site

PublicWeb
AdminWeb
Uploads
Documents
Images

Never underestimate the power of human stupidity
RAH

I usually store uploads in a database. Any reason you can't do that?
