I'm working to lock down our business application which is Silverlight and a WCF data service.
My first attempt really locked down the service...couldn't even get at the wsdl file from VS2008!
I also can't find exactly how to confirm that the windows identity is passed to Silverlight.
What I want: can't run the Silverlight app unless signed on. calls to the wcf service pass the credentials. WCF lets all transactions occur except updates which are locked down to 3 ntlm groups.
I'm not looking for code here. I'm looking for any article here or on the net that gives me a step by step process for doing the lockdown. Most of the stuff I've seen assumes I know what I'm doing ... which I'm not. 
Thanks,
Michael

Hello
Can someone point me into the right direct on how to do the following task in WPF?
I want to have a master Panel in a window that changes based on what a user selects from a menu. For example the panel initially shows a welcome screen. After the user select a new form button, the panel is cleared and populated by a form containing multiple controls. The user could then select another menu button and the panel is once again regenerated based on the menu selection.
I know how to do this all within the code behind but I see that as being a messy way of doing it and defeats’ the purpose of WPF. How do I do it so that the panel is being populated from xaml? Does this have something to-do with user controls? And creating a new user control for each panel that will be loaded by the menu?
If you know of any good books or tutorials that have examples like this then please let me know, otherwise any help would be greatly appreciated.

The topic says dynamic loading of pages and I think that solves the problem you have outlined.
Is this simple pattern not solving that problem?
1. Have main window with Frame object
2. Load pages into the Frame, by setting Frame.Source
If not, the question is not probably clear enough.
Best regards,
Paul.

Hi
We have a WPF application which runs on kiosk. On idle time (when no customer at kiosk) kiosk will a play flash. There is button at the right bottom of flash. When the user click on that button We need to map/route this button click event to a method in WPF page in which the flash is playing.
Way we have designed forms for playing flash:
First we placed a WebBrowser control inside a "UserControl" which inherits from System.Windows.Forms namespace. In runtime a flash file is assigned to this control and loaded into a "WindowsFormsHost" control placed inside an XAML page
Thanks in Advance

It might be easier if you use the System.Windows.Controls.WebBrowser control.
See the WebBrowserControlSample in the SDK WPF samples, it shows how to interact with the scripts.

Paul.

I have a WPF Window that at loading time generate a variable number of image with this for cycle :
public Window1()
{
InitializeComponent();
int numPos = 5;
for (int i = 1; i <= numPos; i++)
{
Image imageStatus = new Image();
imageStatus.Name = "Image" + i;
statusGrid.Children.Add(imageStatus);
}
}
Now i need to access at this image from a timer that every 10 seconds change the image.Source Property of every image crested at runtime ..
How Can i do this ?

i've found a solution , i have an ImageGrid with only Image Created at runtime :
foreach (Image ctrl in imageGrid.Children)
{
if (ctrl.GetType() == typeof(Image))
{
if (((Image)ctrl).Name == "Image1")
((Image)ctrl).Source = new BitmapImage(new Uri("pack://application:,,,/MyApplication/aleroot.png"));
}
}
with this code i change the image source for my Image Created at runtime .
Thanks anyway.

I started looking into WPF recently for the sake of "research" purposes at work, things got a little slow so I thought I'd check it out to keep busy and the old grey matter churning.
Anyway, since I was playing around, I thought why not get the latest VS2010 RC, things were going OK then BAM, BSOD whilst fiddling with the designer. Thought little of it, and dropped down a step to VS2008 (we currently use VS2005/.NET 2.0), things were going OK for about half a day then all of a sudden the designer was failing to load at all, the markup view was fine as was the C#. When left for about half an hour the whole thing would grind to a halt of a sudden and display an out of memory error in the designer.
It all seemed odd, but it was the end of the day and I left it, came back in today, and out of interest my coworker suggests dragging VS over to the main screen (left) and like a flash, the designer came back to life. Dragged it back over to the right (where I normally like to have VS) and it hung instantly, back to the left and it lives! Unfortunately I did this one too many times and the whole thing BSOD, which then made the VS2010 BSOD make more sense as that's written in WPF.
Anyone run across this problem before? (XP SP3)
Cheers
[EDIT] Now it's happening on the left screen after fiddling with the designer for a couple of seconds, checked my drivers and they're up to date. [/EDIT]

Ended up just upgrading to Weven at work earlier than planned, seems ok, but obviously not the most ideal solution for everybody

First thing to do is make sure that the location you want your pages to be show is a NavigationFrame.
(I think that is the right name for it -- on my home machine not my development machine)
Next thing to do is in the treeview a generic way to provide what to load you want to keep the location/name of the page in the Tag of the control.
Finally when you capture the event Navigate:
HtmlPage.Window.Navigate(new Uri(urlString), targetString);

I use DrawingContext to do the visual job
I have tried BezierSegment,QuadraticBezierSegment,PolyBezierSegment
but they not worked
they need control points
so the count of the points are confined
and the joined curve was not smoothing
Is there any way in WPF could solve it?
a smoothing curve just like DrawCurve() in Graphic will be ok.
thanks for any answers.

Hi shoeb,
There is probably no proper way to learn anything. It just takes time and effort.
I would start here : Windows Presentation Foundation.
It's well possible to learn C# separately from WPF. The thing in common between them is the .NET framework. You could also choose VB.NET.
Download VS Express, create a WPF forms app and you're in business. From there bootstrap yourself with knowledge gained from books/internet.
Many happy hours toying with .NET,
Sytse

Hi,
How can I set a custom link for downloading silverlight if it'n not installed on clients
Best wishes

I have two project Silverlight and WCF service. When i try to call the WCF service it gives me error
An error occurred while trying to make a request to URI 'http://localhost:1554/DashboardWCFService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details
can anyone help me in this why i am getting this error.
