I am try to upload files from my computer to a server machine using WCF in Silverlight. Often i can achieve this but sometimes there occurs a problem and stops uploading. Silverlight error is: "The remote server returned an error: NotFound." and at the status bar of the web page there is a black exclamation mark in yellow triangle says error at page. This is details of it: unhandled error in silverlight 2 application at System.Net.Browser.AsyncHelper.BeginOnUI(SendOrPostCallBack beginMethod, Object state) at Syste.Net.Browser.BrowserHttpWebRequest.EndGetResponse (IAsyncResult asynResult) at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse (IAsyncResult result) at ....
And after i found where error occurs
(wsUploader is my WCF and svluploader is silverlight project.)
public svlUploader.wsUploader.UploadResponse EndUpload(System.IAsyncResult result) {
object[] _args = new object[0];
svlUploader.wsUploader.UploadResponse _result = ((svlUploader.wsUploader.UploadResponse)(base.EndInvoke("Upload", _args, result)));//<b>error occurs in this line</b>
return _result;
}
So help me....

If you haven't already, maybe try turning on the
includeExceptionDetailInFaults service behavior
option in the web.config...
<serviceDebug includeExceptionDetailInFaults="true" />
If you can't catch the exception in the debugger, you may need
to use something like Fiddler to capture the fault response with
the exception info in it.
Regardless, it's hard to guess without more detailed error info...

Connect directly to your wsdl and confirm that you do not have problems with your wcf service itself.
NotFound is a really poor messaging error which means basically "something's screwed up" and has nothing to do with something not being found.

I am needing some help with the second part of my application. I have uploaded these files for you to look at. These are at:
http://www.4shared.com/file/172290058/6db0136e/Noe_S2_Web.html,
http://www.4shared.com/file/172290145/bd834a5/3cI_noe.html,
http://www.4shared.com/file/172290211/7384baa0/Test_Data.html
Basically, what I am wanting to do is filter the contents of two text boxes into two other textboxes above and below a range that a user has entered into a textbox. So, for example, if someone where to enter the S2 value in the box of ("0.75"), then the programme would return all values above and below this range from the noe richtextbox. So it is basically taking the value in the S2 data range, the residue (Res) and matching it with the corrosponding NOE value. Within the S2 file, ignore all the other values other than S2 and Res. This means, that for each line in the noe file:
assign (segid HRV and "resid 168" and name HN) (segid HRV and "resid 137" and name HD2) 5.500 3.7 0.0 ! hinnoesy.96 or (segid HRV and resid "168" and name HN) (segid HRV and resid "137" and name HE2)
assign (segid HRV and "resid 167" and name HN) (segid HRV and "resid 167" and name HG#) 5.500 3.7 0.0 ! hinnoesy.110 or (segid HRV and resid "167" and name HN) (segid HRV and resid "167" and name HB#) assign (segid HRV and resid 126 and name HN) (segid HRV and resid 126 and name HA) 5.500 3.7 0.0 ! hinnoesy.350 or (segid HRV and resid 126 and name HN) (segid HRV and resid 130 and name HA)
...You would enter a S2 value into the textbox within range, and it would match up the residue value with the corrosponding noe data, as well as sort according to the parameters in the textbox. So, it would need to output the whole sorted noe file line into the high and low range textboxes. I.e. the first residue is 1, with a value of 0.273. Any value above and below this with the resid within the noe file will take the whole line and place in the corrosponding textbox.
I am very stuck with how to do this, so if someone could please have a go, it would be much appreciated. Thanks.

I am very new in multithreading. I tried to read some topics but confused with different synchronization techniques used in .net multithreading like Mutex class, semaphore, critical section, event, wait handle and monitor.
Can any body guide me or can we do online conference or is there any in-depth video tutorial in multithreading ?
|

This question is far too general. If you need to learn multi-threading then find a tutorial or book that covers the subject in detail. This forum is for answering more specific questions, but does not have the facitlity for teaching you a new subject. My personal recommendation would be to make sure that you are fully skilled in the language of your choice before you try to apply multi-threading techniques to your programs.

For simplicity I have a 6 color cube (Every side has different color) and viewing with a camera. I would like to show same cube from opposite angle with diffrent camera. Both views are visible at the same time. First view works fine but when I want to add the cube in second view where different camera is installed, I get the error that the cube is already added to another view (which is true). I am unable to add one object to 2 views. Any idea how this can be done in WPF? Your help will be very much appreciated.
Best regards

Guys,
I'm just picking up silverlight and Ria services, and must admit I'm a little frusterated. I have a working example of querying via ria services and binding to complex controls such as data grids, but if I try to use that same logic on something like a textblock, I get no love. I assume it's the asyncrhonus nature of the call, but every single example I find uses a darn data grid. Here is what I'm doing:
code behind:
SellerDomainContext domainContext = new SellerDomainContext();
SellerGrid.ItemsSource = domainContext.Sellers;
FirstName.DataContext = domainContext.Sellers;
LastName.DataContext = domainContext.Sellers;
domainContext.Load(domainContext.GetSellerByUsernameQuery("joe_seller"));
xaml:
<TextBox HorizontalAlignment="Left" Margin="8,8,0,19" Width="212" x:Name="FirstName" Text="{Binding TimeOfDay, Mode=OneWay}" />
<TextBox HorizontalAlignment="Left" Margin="8,8,0,19" Width="212" x:Name="LastName" Text="{Binding LastName, Mode=OneWay}" />
<data:DataGrid x:Name="SellerGrid"></data:DataGrid>
As I said, the grid works fine, the first and last name text blocks do not. Any links to articles or code snippets to instruct me on how to do simple data binding to objects such as a text block via ria services would be much appreciated!
Thanks again,
Ryan

In the current RIA services, DomainContext queries ALWAYS return
a collection of entities, not a single entity.
A collection will not have the "LastName" property on it...
that's a property of your entity class (I'd assume  )
First, if you haven't already, upgrade to the latest WCF RIA
services (here: WCF RIA Services[^])
Then your code behind could be changed to something like this:
using System.Linq;
...
SellerDomainContext domainContext = new SellerDomainContext();
domainContext.Load(domainContext.GetSellerByUsernameQuery("joe_seller"), getSellerByUsernameLoadOp_Completed, null);
...
void getSellerByUsernameLoadOp_Completed(LoadOperation loadOperation)
{
if (loadOperation.HasError)
{
loadOperation.MarkErrorAsHandled();
}
else
{
SellerGrid.ItemsSource = loadOperation.Entities;
FirstName.DataContext = loadOperation.Entities.FirstOrDefault();
LastName.DataContext = loadOperation.Entities.FirstOrDefault();
}
}

I'm trying to speed up the initial loading/busywork of the my Silverlight app. Right now once the Silverlight app is loaded on the client it makes an async call to the server to get data for its dropdown fields. I'd like to cut out this round trip.
Is there any way I can load the data from the DB and send it to the client with the initial request for the Silverlight app?

You can't do it from your Silverlight app because until the
Silverlight app is downloaded and running, none of your
Silverlight code runs.
You can, however, break your Silverlight app into parts so
the initial part is small so it downloads faster:
How to: Load Assemblies On Demand[^]
Also, searching on "silverlight application load time" or
"silverlight load on demand" yields many articles like these:

I understand that Silverlight app itself can't do this. I was hoping there might be a way to send a resource down with the Silverlight app that it could have waiting for it once it started running. Kinda bundle the 2 things together.
...doesn't seem to be an option.

If it's a static resource, you can bundle it in the app's XAP file.
If it's dynamic data, you could certainly add stuff to the xap file before
it gets requested, but how would you initiate that on the server? You'd
have to do that from the hosting webpage...

Hi,
To get Rounded edge Listbox i searched for samples and finally get that.Here my code.
In XAML:
<ListBox Margin="22,122,27,126" Style ="{DynamicResource RoundedBox}" Name="listBox1" Background="DarkSeaGreen" Foreground="Yellow" SelectionChanged="listBox1_SelectionChanged" >
in ResourceDicationary WPF.XAML
<Style x:Key="RoundedBox" TargetType="{x:Type ListBox}">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" />
<Setter Property="BorderThickness" Value="3"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="0,0,1,1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBox}">
<Border CornerRadius="5,5,5,5" BorderThickness="1,1,1,1" RenderTransformOrigin="0.5,0.5" x:Name="border" BorderBrush="#FFFFFFFF">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform ScaleX="1" ScaleY="1"/>
<SkewTransform AngleX="0" AngleY="0"/>
<RotateTransform Angle="0"/>
<TranslateTransform X="0" Y="0"/>
</TransformGroup>
</Border.RenderTransform>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Finally i got the rounded edge but..the background colr has gone and now it is transparent.
What im missing?Im new to WPF.Pls help me.
Before inclcuidn resourcedictionary in XAML,it shows the clor.After i inserted the line
Style ="{DynamicResource RoundedBox}" ..the colrs goes but i get rounded edge listbox.

Maybe set the Border's Background property...
<Border Background="{TemplateBinding Background}" CornerRadius="5,5,5,5" BorderThickness="1,1,1,1" RenderTransformOrigin="0.5,0.5" x:Name="border" BorderBrush="#FFFFFFFF">

Your template doesn't provide an items host.
There's an example of a rounded listbox in the documentation
(scroll down to see the different samples):
ItemsControl.ItemsPanel Property[^]
There's also a complete sample template for listbox and many
other controls...

I am wondering if anyone can point me to some code (or DLL) to build a native OpenFileDialog and FolderBrowserDialog in wpf / xaml, rather than using the System.Windows.Forms controls?
We have now replaced the Forms MessageBox with a native WPF taskdialog, which looks much better and behaves more consistently. I would like to do the same for OpenFileDialog and FolderBrowserDialog.
Thanks,
Tim

WPF has a OpenFileDialog class in the Microsoft.Win32 namespace.
For Folder Browser dialog, see my blog[^]
I thought Pete O'Hanlon was working on a WPF version at one time
It's definitely a project to make a WPF version to replace the OS
dialogs...

I have been working on one - it's something that I keep coming back to when I have some free time. It's a hell of a complex beast though, as I'm trying to make it completely skinnable.

I've only just been able to get back to this question - sorry for the long delay in responding. I guess it looks like this is a complex issue - I'll keep wrapping the System.Windows.Forms controls for the time being, and look out for further developments on this question. Hopefully Microsoft might build something into a future version...
Thanks,
Tim
