I want to access files (images, text files etc.) from an USB stick on my Raspberry Pi 2 using Windows 10 IoT Core.
So I've added the to the appxmanifest file.
When using this code in my IBackgroundTask I get an access denied error in the second line:
public sealed class StartupTask : IBackgroundTask
{
public async void Run(IBackgroundTaskInstance taskInstance)
{
//...
Windows.Storage.StorageFolder sf = Windows.Storage.KnownFolders.RemovableDevices;
//get list of drives
IReadOnlyList<Windows.Storage.StorageFolder> list = await sf.GetFoldersAsync();
...
}
}
I found that I should add the fileTypeAssociation with the file types I'd like to access in Package.appxmanifest so I did that:
<?xml version="1.0" encoding="utf-8"?>

If I want to deploy that, I get the following error:
Severity Code Description Project File Line Suppression State
Error Error : DEP0700 : Registration of the app failed.
AppxManifest.xml(37,10): error 0x80070490: Cannot register the
test-uwp_1.0.0.0_arm__yzekw4x8qxe1g package because the following
error was encountered while parsing the windows.fileTypeAssociation
Extension element: Element not found. . Try again and contact the
package publisher if the problem persists. (0x80073cf6)
As soon as I remove the uap:Extension element, the error goes away (but the access denied is still there).
Did I miss anything? Is it not possible to access files from an USB stick using a background service (I want to run that headless with no user interaction)?
At the moment you can't register a headless app that uses filetypeAssociation.
There is a workaround - see here: https://github.com/ms-iot/ntvsiot/issues/62
Simply add a headed app (project) to your solution (no need for any special code there).
Add a reference to this project in your headless app.
Now change the manifest of the headless (file asso..) and add Executable: YourHeadedApp.exe and EntryPoint: YourHeadedApp.App now with the next deploy the EXE will be included in deployment - so it can be found when the manifest is checked.
I'm devoloping a windows service which requires a socket connection to my server to do its job. I made the service establish the connection through a thread that is started on the OnStart service's event. It worked until this morning when I've compiled it again after some changes I've made: it crashes on the initialization of the client variable. Here is the part of the code where it crashes:
Try
client = New TcpClient 'the error is here
client.Connect(ip, port)
stream = client.GetStream()
receiver.Start()
tryingconnect_thread.Abort()
Catch ex As Exception
File.WriteAllText("C:\error.txt", ex.Message) 'here it gives me "Configuration system failed to initialize"
System.Threading.Thread.Sleep(10000)
End Try
To be sure I also tried the Try Catch End Try statements only with the initialization in it.
How can I solve this problem?
I've already seen other questions like this, but none of them worked.
EDIT:
This is the exception:
System.Configuration.ConfigurationErrorsException: Impossibile inizializzare il sistema di configurazione ---> System.Configuration.ConfigurationErrorsException: Sezione di configurazione authentication non riconosciuta.

</configuration>
I've just found the solution: simply remove the
<authentication mode="Windows" />
<identity impersonate="true" />
part from the config file.
I'm not entirely sure what's going on with this. The application works absolutely fine on my machine, but when being launched on another machine, it crashes at launch. This is the error log of the .NET Runtime:

This was all done with Visual Studio 2010. Any ideas? It's been an issue plaguing this project for a while.
We recently upgraded our web app from 3.5 to 4.0. Now after I login and load a page with Microsoft ScriptManager on it, I get:
Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.
It only happens the first time, reload the page and everything works.
UPDATE: We have all Silverlight v4 projects.I found the System.Windows.dll in the C:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0 directory. Why would it look for version 2.0?
Here's the entire exception (edited and removed folder paths)

Edit: I'm running VS 2010, XP with IIS 5.0 (I miss Win 7 at work every day :-)). We have the web app running under the local IIS instance, not Cassini. We deployed it to a test server and I did not see the exception. After I installed the C:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0\System.windows.dll to the GAC and then removed it and haven't seen the same exception, though my colleague hasn't done this and still sees it occasionally. I think it only happens when the app is restarted (which happens every time we rebuild the app when developing locally).
Sounds like one of the projects in your solution is referencing the v2 system assemblies. Make sure that all of your projects and application pools are set to use 4.0. You can set this in the project properties in Visual Studio.
(Note that you'll have to rebuild your solution with the new settings if you haven't already).
I have been having the same issues for a long time, but just found some old Silverlight Assemblies in my bin folder, removed those and voila.. error gone
Adding reference to AjaxControlToolkit.dll and adding the header
<%# Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
to the aspx that contains the script manager solved the problem for me.
this is going to steal my sanity. I've been gone through almost everything I found on the web and went no single step forward. Frustration is not strong enough to describe this errormessage come popping up regardless of what I am doing.
But one after the other.
I have a 64bit W2008 Server machine with VS 2008 SP1 german version, Silverlight Tools 3.0
I want to consume a WCF-Service from a Silverlight application. And, as many people, I get this very frustrating non-descript Communication Exception at the end of the invoke.
I created a new WCF-Service, named an Endpoint and set its binding to basicHttpBinding. I added the attribute
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
to the Service1 class and the line
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
to the system.serviceModel in the App.config
I left everything else as it is and tested the service via WCF-client successfully. Then I published it to my local IIS7 to http://localhost/WCFTest
Within my Silverlight application, I added the service to the Servicereference using http://europa.therestofmydomain/WCFTest/WcfTest.Service1.svc
I added the following code to the client:
using OSMDeepEarthExample.ServiceReference1;
...
Service1Client s1 = new Service1Client();
s1.GetDataCompleted += new System.EventHandler<GetDataCompletedEventArgs>(s1_GetDataCompleted);
s1.GetDataAsync(20);
void s1_GetDataCompleted(object sender, GetDataCompletedEventArgs e)
{
CountFetchedData.Text = e.Result;
}
I added a clientaccesspolicy.xml AND a crossdomain.xml to the webroot (C:\inetpub\wwwroot)
clientaccesspolicy.xml:
<?xml version="1.0" encoding="utf-8"?>
<access-policy>
<cross-domain-access>
<policy>
<allow-from>
<domain uri="*"/>
</allow-from>
<grant-to>
<resource path="/" include-subpaths="true"/>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
crossdomain.xml:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
<allow-http-request-headers-from domain="*" headers="SOAPAction" />
</cross-domain-policy>
I restarted the IIS. Twice. Often.
I installed Web Development Helper to maybe get more meaningful information about WHAT is wrong. But this makes the IE crash.
I am out of ideas. And soon start to be aggressive against my hardware. Please help my hardware!
As John noted, I did forgot the full Errormessage here it comes:
Fehler beim Senden einer Anforderung an den URI "http://europa.therestofmydomain/WCFTest/WcfTest.Service1.svc". Ursache ist möglicherweise, dass ohne die entsprechende domänenübergreifende Richtlinie oder mit einer nicht für SOAP-Dienste geeigneten Richtlinie domänenübergreifend auf einen Dienst zugegriffen wurde. Möglicherweise müssen Sie sich an den Besitzer des Diensts wenden, damit eine domänenübergreifende Richtliniendatei veröffentlicht und das Senden von sich auf SOAP beziehenden HTTP-Headern zugelassen wird. Dieser Fehler kann auch durch Verwendung von internen Typen im Webdienstproxy ohne das InternalsVisibleToAttribute-Attribut verursacht werden. Weitere Details finden Sie in der inneren Ausnahme.
In short, it says there may be an interdomain rule be missing.
Whew, I've done it!
I removed the clientaccesspolicy.xml from the webroot, leaving only crossdomain.xml there. What an odyssee! Thank you for listening, it helped to clear my mind. I hope someone with a similar problem will find the text helpfull a little bit!
