HI,
I'm working on a card game and am curious how to design my Card class (each of which are held in a CardDeck class which extends List<Card>. The card is not a typical playing card, instead having a title and description as well as a unique Image on the front.
During play, the cards need to be displayed and moved in a some sort of layout panel. I've created the basic Card object with the following properties:
public string Title
public string Description
public Image CardFront
private Image CardBack
I thought of extending the Card as an Image or as a Viewport. But being new to WPF (and .NET Windows application programming) I'm not sure the best way to implement it.
Thanks,
Chris

I like to show my forms with silverlight option, is it possible? This is the first time I am trying...
My idea is while the datas are readonly, then the form opening time if we show the silverlight option then the user can easily identify that it cannot be change...
So, Any better guidences...
Thanks...

Amazing how many people try to use a technology without even knowing what its for.
Silverlight is for Web applications not Windows applications. For Windows you need to use WPF.
If your controls are readonly I think that would be a pretty big hint to the user that it can't be edited.

Dear friends,
i have a clarification ...
I have canvas with few paths like these
<canvas>
<Path name="path1" ..../>
<Path name="path2" ..../>
</canvas>
now i have style for canvas ...in that style is it possible to change the property of the "Path1"???
[Because i have problem like these .. i have few paths in canvas if i move a cursor on any path .. i have to change the property of "Path1" .. so i think working on the canvas will make possible]
Thank you

It would help if you actually showed the paths."WPF has many lovers. It's a veritable porn star!" - Josh Smith As Braveheart once said, "You can take our freedom but you'll never take our Hobnobs!" - Martin Hughes.

Hi,
I want to provide automatic file download when the user clicks on a (hyperlink)button. Can someone shed a light on how to specify URI correctly for the file protocol in the following code:
private void FileDownload_Click(object sender, RoutedEventArgs e)
{
System.Windows.Browser.HtmlPage.Window.Navigate(new Uri("file:///1.zip"), "_blank");
}
It works fine when I use the absolute file path. But how do I specify the relative file path, because I don't know the absolute path on the hosting server?
Thanks,Best,
Jun

Hi Jun,
If you specify UriKind.Relative in the Uri constructor, it will be relative to the page hosting your Silverlight app.
System.Windows.Browser.HtmlPage.Window.Navigate(
new Uri("SubDirectory/TextFile.txt", UriKind.Relative), "_blank");
Cheers,
Daniel

Thanks, Daniel. It works.
One side note, though. I couldn't make the complete format work:
System.Windows.Browser.HtmlPage.Window.Navigate(
new Uri("file://SubDirectory/TextFile.txt", UriKind.Relative), "_blank");
It appears that if I use "file://", I must quote the absolute path.Best,
Jun

Hi,
I have build a silverlight site and uploaded it to my hostint server "DiscountASP.NET". The IP is "www.entribute.com". I can browsw it from my development machine without any problem. However, when I visit it from another Vista PC, I got a "Could not download the Silverlight Application" error. Many posts say it is a MIME type issue on the server, but why can I open it fine from my development machine?
Thanks,Best,
Jun

I just tried it from here using IE6. I can get to my Silverlight sites no problem but yours gives the following error:
Line: 56
Char: 13
Error: Unhandled Error in Silverlight 3 Application
Code: 2104
Category: InitializeError
Message; 2104 An error has occurred
Code: 0
URL: http://www.entribute.com/

Ok, I have figured it out. It seems that the path for the compressed source code should be
<param name="source" value="ClientBin//EntributeSilverlight.xap"/>
not
<param name="source" value="ClientBin/EntributeSilverlight.xap"/>
Both work well on the local host but only "//" works on the hosting server.
Thanks,Best,
Jun

Hi,
We have a strange problem. Our WPF C# application is run on many different Windows OS. At the moment we perform sleep/resume tests and it work fine on all OS but not on XP 64 bit. We get strange crashes on different places in the code. When enter sleep state our application sometimes crashes, and I can't get to usefull information from the crash log. We have try catch arond the running threads but we cant catch the exception.
System.ArithmeticException: Overflow or underflow in arithmetic operation.
Data: System.Collections.ListDictionaryInternal
Source: WindowsBase
TargetSite: System.Object.Invoke(System.Windows.Threading.DispatcherPrioritym System.Delegate, System.Object)
Has also got TimeSpan exception get_TotalMilliseconds()
Source: mscorelib
But I cant see that milliseconds can be a strange value?
I get a some different exceptions. And not a useful stacktrace.
Anyone who have some smililar problems?
Regards

Hi. Any silverlight I put in my page cover's every other element on the page(even if that element is z-indexed to be in front). This only happens in IE.
I remember having a similar problem with Flash but cant find a SL equivalent solution. Someone suggested setting Windowless to true. But that disabled the silverlight so you couldnt click in it.
ThanksStrive to be humble enough to take advice, and confident enough to do something about it.

I have this
But when I set display to block to show the div the silverlight box is just white, with no content loaded. Even if I set the div to block to start with(in which case the SL box works) then hide it and display it again, the SL still doesnt work.
I need to be able to hide and show silverlight clientside.

Can anybody see what's going wrong here? I get an empty grid with a blank row for each item in the ObservableCollection .
<Custom:DataGrid Width="454" Height="396" Canvas.Left="8" Canvas.Top="4" Name="gridEvents" FontWeight="Bold" FontFamily="Nina"
AutoGenerateColumns="False" SelectedIndex="0" FontSize="10.667" >
<Custom:DataGrid.Columns>
<Custom:DataGridTextColumn x:Name="dgCol_EVStatus" Header ="Status" FontWeight="Normal" IsReadOnly="True" />
</Custom:DataGrid.Columns>
</Custom:DataGrid>
and
dgCol_EVStatus.Binding = new System.Windows.Data.Binding("Status");
ObservableCollection<RIAudit> _Audits = new ObservableCollection<RIAudit>();
_Audits.Add(auditRec);
gridEvents.ItemsSource = _Audits;

redivider wrote: AutoGenerateColumns="False"
I think you want "AutoGenerateColumns="True""
corrected spelling
My bad I did not read the entire thing obviously. You don't need the Autogeneratecolumns since you describe one already. But what happens if you let the grid autogenerate the columns for you? And/or the grid might not understand how to display an RIAudit object.Why is common sense not common?

Hmmm.. Figured something aggravating out. RIAudit, out of necessity, uses public properties, instead of accessors. If i change
public string Status;
to
public string Status {get; set;}
then WPF is happy (though the object-ralational database i use is not).
I guess I'll have write a wrapper for RIAudit, unless someone knows how to get around this. ??

Every one of us has downloaded dozens of executable files from the Web, but for the life of me I can't find out how this is done. Every time you go to a commercial site that offers software for free or for sale, you can click on a download button and a standard dialog with the title, "File Download - Security Warning," pops up with Run, Save, and Cancel buttons.
What do you have to do to bring up this dialog? This obviously isn't a Silverlight-specific question, but searching the general Web forums mysteriously don't seem to answer this question, either. But I have to get this standard dialog coming up from my Silverlight app. If you could just point me to the right subject in a book somewhere, I'd be eternally grateful.
I know there are security issues about downloading executable files. Nevertheless it's done all the time, through this standard "File Download - Security Warning" dialog that is undoubtedly available through thousands of Websites. I don't understand why this seems to be such hidden knowledge. I have several books on Website development and there isn't a word about this in any of them. Where is it actually documented how to do this?

I've never done any Web programming. Silverlight is my first exposure to it. It's been desktop programming for me ever since I landed my first job that required development for a PC back in 1988. Now desktop programming is passé and I need a new career.
I went to the bookstore today and looked through a bunch of ASP.NET books and Website development books and couldn't find a single one that mentioned this standard "File Download - Security Warning" dialog. If you know the answer, please let me know what it is. Evidently I don't even know the technology that puts out this dialog, so I don't know what kind of a book to look in for the answer.
I also read about the Silverlight SaveFileDialog class, hoping it would give me something like what I need, but the examples I'm seeing are very confusing. I was hoping I would be able to get a Stream from a file on my Website and be able to call some function in the SaveFileDialog class that would let me feed that stream into a file I would browse to with the SaveFileDialog.ShowDialog method, and then save the file with that stream, but evidently that's not how it works. There isn't even a Save method in this class, only an Open method. The OpenFileDialog class has methods like Create and OpenWrite but they are restricted for internal use only.
All I want is hint of where to look to do the research. I don't even know what I should be studying.

I apologize for my sarcasm, but it seemed funny at the time.
As far as I know, the dialog box you're talking about is the duty of the browser to show.
The web server simply serves the file, with its associated MIME type being listed in the HTTP headers.
Now, if the browser sees that it is not a file used for rendering a web page, first it looks to see if it has a registered handler for that type of file. For instance, a WAV file would trigger the browser to launch Media Player.
If there is no registered handler for the specific type of file, then it would open the Save As dialog box.

I don't know Silverlight, but I would guess that it's probably up to you to implement and launch the Save As dialog box yourself.
When you want to download the file in question, open an HTTP connection to the URL, then once you have that, launch the Save As dialog box for the user to choose a location to save the file.
Then all you have to do is alternately read the network stream and write the file.
