Silverlight France Hosting - HostForLIFE.eu :: How to get unrestricted access in Silverlight 5

clock February 10, 2014 07:45 by author Peter

As you all know Silverlight 5 released with unrestricted access in InBrowser mode which gives full control to the Silverlight developers in the client machine. This post is to describe what are the changes you need to do at the server side as well as client side to leverage the trusted application feature.Try HostForLife.eu, only with € 3.00/month, you can get a reasonable price with best service. This topic contains only brief information about why you must use Silverlight 4. So, if you want to be more familiar with Silverlight 5, you should try HostForLife.eu

Server side

- Make the IB elevated from project properties

- Sign the xap using certificate.

Client side

- Install the cert into “trusted publishers”

- Change the reg key “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight\AllowElevatedTrustAppsInBrowser” to

-The “Protected mode” of browser should be turned off for the zone.

The above steps are mainly for Silverlight 4 to Silverlight 5 conversion and want to get the full trust support. If you just upgrading your projects there is no need to do above items. Just open in Visual Studio 2010 after installing the SL 5 tools.It will show the conversion wizard and just follows that. One thing you need to make sure is the reference path to Sl 5 assemblies.

Steps to setup Silverlight 5 application to have unrestricted access in IB using elevated trust mode
Ok.Now lets look at details of how we can create new SL project which access a file from c:\ in the In-Browse mode.First as usual create a Silverlight 5 Application. Then place a Button inside and wire the Click event handler.Write the below code in the handler to write a file to c:\

private void btnWriteToCDrive_Click ( object sender, RoutedEventArgs e )

{

    File.WriteAllText(@"c:\FromSL5.txt","This is written from Silverlight 5 web application in InBrowser mode");

}

Giving Elevated trust to SL 5 application

Just to go to the Silverlight 5 project properties and in the Silverlight tab check the “Require elevated trust when running in-browser” check box.See the below screen shot for reference.

Signing the xap
Next step is to sign the xap file with a certificate. Just goto Silverlight project properties and check the “Sign the Xap File” check box.If you don’t have any certificate just create a new one using the “Create Test Certificate” button.

Disable the browser protected mode

The above changes are mainly for the server side. You need to do some at client side as well.The first one is to disable the protected mode in browser.Goto the internet options and disable it.

Change registry entry

As mentioned above just change the registry entry as it is.If you cant find the key just add a DWORD and set to 1. Still I am not sure how this step is carried out in other platforms such as MAC and Linux. That’s it.Now run your application.It will create a file inside c:\ from in browser.Just uploaded the sample by removing the certificate as it give some information about my company laptop.



Silverlight Hosting - HostForLIFE.eu :: Bundling native DLL:s in Silverlight 5 RC applications

clock February 5, 2014 18:12 by author Peter

One of the many interesting new features in Silverlight 5 RC is the ability for elevated trust applications (in-browser as well as out-of-browser) to access native DLL:s via P/Invoke.
Some interesting application examples are given here and here. These examples show how easy it is to access system DLL:s such as user32.dll, kernel32.dll and psapi.dll. However, the issue appears to be more complex when it comes to native DLL:s that are not automatically available on the system.
Ideally (I think), you would like to bundle the native third party DLL:s as Content in the XAP file, and the XAP file would be artificially included in the P/Invoke search path. Unfortunately, this is not the way it works today. When I bundle my third-party native DLL as Content in my Silverlight 5 RC application, and try to access one of its methods via the following declaration,

[DllImport("NativeDll")]

public static extern int add(int a, int b);
I get a discouraging DllNotFoundException. It does not help if I add the .dll extension to the file name, and I have also not been able to find the DLL by applying any of the pack URI approaches to the DLL file name.
Several people, including myself, have brought up this issue in various forums, but so far I have not seen any published solution to the problem.
Well, as we say in Sweden, "själv är bäste dräng" (which is similar to "if you want something done, do it yourself"), so here is my attempt to solve the problem. Granted, it might not be the most Elegant Solution, but at least it is A Solution.
It is important to note that this solution is applicable primarily to Silverlight 5 RC. In the best of worlds, Microsoft will fix the native DLL path issue in the RTM release of Silverlight 5, and then this solution would be superfluous. We'll see what happens in the end.Note also that since P/Invoke is a feature requiring elevated trust, this solution is only relevant to applications running in elevated trust (in- or out-of-browser).

In short, the solution is to bundle the native third party DLL:s as resource files in the Silverlight 5 RC application, and when the application is started copy these DLL:s to a local directory and add the directory to the system path during the execution of the Silverlight application.In more details, here is how it can be done:Add each native third party DLL as an existing item to the root folder or, even more preferably, to an assets sub-folder in the Silverlight 5 RC application project.

In the File Properties window, set Build Action to Resource and Copy to Output Directory to Copy if newer.

The DLL copying and PATH environment variable setting of course requires some additional code. Fortunately :-) I have created a static utility class for this purpose. The class is named NativeDllHelper and can be found it is entirety here. Download and add this file to your Silverlight 5 RC application project.

Next, go to the App.xaml.cs or equivalent file. Add the following using statement.

using Cureos.Utility;

In the Application_Startup (or equivalent) event handler, add the following method call to the first line of the event handler.
NativeDllHelper.SetupNativeDllFolder("relpath/dllname.dll", ...);

where relpath is the path relative to the project root folder where the native DLL:s are located, and dllname is the file name of the DLL. Specify all DLL:s to be copied in one argument list; the SetupNativeDllFolder method should only be called once at start-up to avoid adding duplicate entries of the local DLL directory to the system path.
The native DLL files are copied to a My Documents sub-folder Silverlight\Native. If you prefer a different folder for the DLL:s, edit the static constructor of the NativeDllHelper class.

Here is an example call of SetupNativeDllFolder, copying one file NativeDll.dll located in the Assets sub-folder of the Silverlight 5 RC application project.
NativeDllHelper.SetupNativeDllFolder("Assets/NativeDll.dll");
Having performed these steps, no user intervention is required when running the application, the native methods in the third party DLL:s can simply be invoked using only the file name of the DLL:
[DllImport("NativeDll")]
public static extern int add(int a, int b);

A complete example SL 5 RC application utilizing this functionality can be downloaded from here. Note that it contains a C(++) project for creating the example native DLL.
If you try out the application and get build errors due to copy prevention the first time, building a second time should do the trick. You might also need to manually set the start page of the Web project to the .aspx file.

The application itself is very simple; there is this button

with the following click event handler associated to it:
private void Button_Click(object sender, RoutedEventArgs e)
{
  button.Content = add(5, 7);
}

The add method is a native method, as declared above. Clicking the button leaves us with the following satisfying button update:
And that is basically all that there is to it. The utility method for copying DLL:s from the application resources can most certainly be further improved, for example by more efficiently handling DLL:s already existing locally. With the current implementation, any existing DLL:s are automatically overwritten. All improvement suggestions as well as reports of successes or failures are highly appreciated.
