I suspect you may have the key to my problem as well. I'm running a C# .NET web service under IIS with an accessible ClientAccessPolicy file too. I can call the service from an SL2 app running on the same machine and another machine running on the same intranet but not from an apparently different domain.
Thoughts?

Ugh.
Are you able to add a service reference (from scratch) by running VS2008 on a PC in the different domain? IOW, SL aside, are you even able to see the service from the PC on the different domain?

Hello Ravi
I can see the service description page from the external site (1 below).
It all gets a little complex as the only way to test this is to use a GotoMyPc connection (essentially Citrix) to a machine 300 miles away in London and browse back to my desktop here!
Here are 3 URLs - youll need SL2 RTW for #2 to work. What do you see?
1. Raw service: http://ubik8.dyndns.org/novaserver/service1.asmx[^]
2. SL2 app which calls the above: http://ubik8.dyndns.org/novaclient/default.html[^] Just press the Connect button.
3. and the policy file ... http://ubik8.dyndns.org/novaclient/clientaccesspolicy.xml[^]
BTW on the remote machine I used IE7 with the WDH extension added. It gives no clues. Why is this so complicated .. I'd have expected the SL2 <-> IIS Web Service to be an extremely common use case.
Thx
Jerry

My thoughts exactly. 
I can see your config file in my browser - it looks good. However, I think it's the SL client that's impeding access and not your firewall or webserver setup; I don't see the app trying to access CAP.xml.

Does anyone know how to listen to a custom static event in a .NET control from silverlight?
I cant add the reference to the .NET dll as VS2008 complains about it not being a silverlight assembly.
Anyone got an ideas how i'd get around this?
Regards,
Gareth.

You can only reference DLLs compiled in SL from SL projects. So, you will need to build the DLL you trying to reference in SL. SL contains a subset of .net (as well a subset of WPF).

We are developing W PF application which uses .net framework 3.0 for compilation.We are not getting error in runtime or during compiling/debugging. But When we deploy the same application in the system in which visual studio 2008 is not installed we get the following error occurs when navigation takes from one page to other page.
system.windows.xamlparseexception
cannot create instance of "Page1" in defined assembly.
exception has been thrown by target of an invocation
error in markup file 'page1.xaml'
system.reflection.targetinvocation exception
exception has been thrown by target of an invocation
system.ArguementException:Arguement Prompt cannot be converted to type string
could anyone please help us asap?

I'm not sure what Prompt is.
Would it make more sense to load .NET 3.5 SP1 on your development machine and target machine? Eliminate issues like this?

Hi guys.
In SilverLight we can use C#.NET or VB.NET for programming or we should use Javascript ?
Many thanks in advance
|
|
|
|
|
If you're using Silverlight 2, you can use C# or VB.NET. If it's pre version 2, you had to use JavaScript.
|
|
|
|
|
Thanks Pete. You truly are an expert.

So if we use C# or VB, it will be Server side ? yes ?

Well yes and no. The beauty about Silverlight 2 is it runs a low footprint CLR in the browser.

You can use either C# or VB.NET. Pick which ever one suits you best

But in Silverlight1 I couldn't use C# !!!

Which is why I didn't really look at Silverlight until Silverlight2. Are you developing in Silverlight1? If so, you should move to Silverlight2

I'm building a proof of concept using VS 2008 and the very latest Silverlight 2.
What do I need to do to deploy to a commercial host? DiscountASP.net in this case. Is it simply a case of copying the contents of \release onto the server? Where is the FAQ on this topic - seems to be AWOL
Any help appreciated.
Thx++

I'd be interested in how that works too. There isn't anything useful in the help file about it...I'm thinking that it's the same as deploying an ASP.Net based site, so you might look from that perspective.
I did find one potential 'gotcha' about mime-types that I didn't know about here[^]
|
|
|
|

Hello David
Thanks - the addition of a 'publish' option in VS 2008 would have been a really good idea I think!
I hope I've persuaded the DiscountASP.Net people to write up a KB article about it.

|

Totally agree...feel free to share your hard earned knowledge here in the Silverlight forum when you get it

You could always write one, based on your experience with Silverlight and commercial hosting, and post it here on CP.

I managed to get a test Silverlight 2.0 Application working on my local copy of IIS 6.0/WinXP Pro...some things to know:
- It seems to work best if debugging is turned off in Web.Config, to change it, from VS2008 menus, go Website-->ASP.Net Configuration...that brings up an add-on for managing the security settings etc for your project.
- Mime-types: I found references for 2 mime types that need to be added in your IIS Control Panel:
- .xaml = application/xaml+xml
- .xap = application/x-silverlight
...see here[^] for the .XAML and here[^] for the .XAP This[^] is another reference to the mime type issue. If you add these yourself, make sure not to forget the period in front of the extension, or it doesn't work eg: '.xap' not 'xap'
- .Net 3.0 and 3.5 in Silverlight 2.0 still use the ASP.Net 2.0 stuff in IIS, make sure that your virtual directory under IIS is set to use ASP.Net 2.0 ...or your hosting provider has it set.
- When I created my Silverlight Project, I included an 'ASP.Net Website' for testing...I copy the entire contents from that to my IIS virtual folder...if I make changes and rebuild, I recopy the whole thing. The other project which is the actual Silverlight project gets compiled into a *.XAP file which is copied to the 'ClientBin' folder of the 'ASP.Net Website' project, so you don't need any files from the actual Silverlight project for deployment. So, if my project was called 'SilverlightApplication', you would wind up with a 'SilverlightApplication.Web' folder...copy the entire contents of that to your IIS folder...the files and folders were:
App_Data (folder)
Bin (folder)
ClientBin (folder with .XAP file)
Default.aspx
Default.aspx.cs
Silverlight.js
SilverlightApplicationTestPage.aspx
SilverlightApplicationTestPage.html
web.config
To load the site from a web browser, I put http://localhost/myvirtualfolder/SilverlightApplicationTestPage.html (or the aspx file).
I'm sure you can name your own files what you want etc...this is just a starting point to get all the pieces working.

I have an xbap application and I would like to hide controls on the page during runtime depending on whether the control is flaged as hidden in an Application hidden field table. Can someone tell me the equivance of reading controls on a page. Below is sample code that I used to read controls on a form before WPF.
private void HideControls()
{
foreach (Control c in Controls)
{
if (c.Controls.Count > 0)
{
}
else
{
if (c.Visible)
{
foreach (BUI.ApplicationHiddenField d in ApplicationHiddenFieldCollection)
{
if (d.Field.ToLower().Equals(c.Name.ToLower())) c.Visible = false;
}
}
}
}
}
Thanks
Jonso

There are several ways to do this.
The best way, is to DataBind the Visiblity property on the control, to a Boolean field on the data that has the value.
You can expose your Application Hidden Field Table as a property on the Window or UserControl, and have the controls in the UI Bind to that property.
You will need to use the BooleanToVisibilityConverter in your binding expression.
By data binding to the Visibility property of the control, you can change the data and the control will collapse, hide or display itself without any additional code.
Just ensure that your data class implements the System.ComponentModel.INotifyPropertyChanged interface.
Another way, not necessarily the best is to walk the VisualTree and set your controls. But I would not recommend this.
If you are knew to WPF data binding, search here on Code Project and the Internet for great tutorials and articles. My blog link below also has a good deal of data binding and links to other great blogs.

OMG. The very first two value converters I wrote (and still use)
were VisibilityToBoolHideConverter and VisibilityToBoolCollapseConverter...
I had no idea that class existed LOL How many other converters are available?
