I could not find any good material for QuickBlox integration. I am coding for metro app and following official docs. that's written for WP7 but somewhere I also read its equivalent to windows 8.
Following is the code and error!
private const int AppID = 150;
private const int OwnerID = 4331;
private const string AuthKey = "8vXrOPEEXFacuEa";
private const string AuthSecret = "Up3AjdkjEDAzraL";
public QuickBloxSDK_Silverlight.QuickBlox QBlox
{ get; set; }
public MainPage()
{
// QBlox is receive null and cause for exception
this.QBlox = new QuickBloxSDK_Silverlight.QuickBlox(AppID, OwnerID, AuthKey, AuthSecret);
InitializeComponent();
}
Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies wp7
QuickBlox doesn't support WP SDK yet
It's open sourced now, check it here https://github.com/QuickBlox/SDK-wp7
You can use it as is and try to port to Windows 8

I am building an aaplication in Xamarin for IOs and sometimes I get these errors.
Microsoft.Practices.ServiceLocation.ActivationException: Activation
error occurred while trying to get instance of type
SurveyNavigationPage, key ""
I can't figure out why am I getting them and can't even trace them to where they are coming from...
I guess I have done something wrong in the Dependancy Injection. I am using Autofac and Service Locator. Below I will demonstrate how I implement the dependancy injection in my project and possibly someone can spot my error.
My code is in the PCL part of the Xamarin project but the error happens iOS Application class for some reason in the UIApplication.Main(args, null, "AppDelegate"); Well at least that is where it crashes if I debug..
My PCL App class instatiates the dependancy injection class like this:
public App()
{
SetUpDIContainer();
InitializeComponent();
MainPage = new NavigationPage(ServiceLocator.Current.GetInstance<MainPage>());
}
private void SetUpDIContainer()
{
var container = new DependencyInjection();
container.Initialize();
}
The Dependancy Injection class looks like this:
public class DependencyInjection
{
private IContainer _container;
public void Initialize()
{
BuildContainer();
SetServiceLocator();
}
private void BuildContainer()
{
var builder = new ContainerBuilder();
builder.RegisterGeneric(typeof(RestRepository<>)).As(typeof(IRest<>));
builder.RegisterType(typeof(PageService)).As(typeof(IPageService));
builder.RegisterType<SurveyController>();
builder.RegisterType<LocationController>();
builder.RegisterType<ClientController>();
builder.RegisterType<RepositoryService>();
builder.RegisterType<MainViewModel>();
builder.RegisterType<SurveyNavigationViewModel>();
builder.RegisterType<EditSurveyViewModel>();
builder.RegisterType<ClientPageViewModel>();
builder.RegisterType<BaseViewModel>();
builder.RegisterType<MainPage>();
builder.RegisterType<SurveyNavigationPage>();
builder.RegisterType<SurveyPage>();
builder.RegisterType<EditSurvey>();
builder.RegisterType<ClientPageView>();
builder.RegisterType<App>();
var http = new HttpClient();
builder.RegisterInstance(http).As<HttpClient>();
_container = builder.Build();
}
private void SetServiceLocator()
{
var csl = new AutofacServiceLocator(_container);
ServiceLocator.SetLocatorProvider(() => csl);
}
}
It is a very strange error as it comes up sometimes and sometimes it doesn't and I can't spot what exactly has to happen in order for it to happen.
I have been struggling with this for several days (three actually). I have AAD B2C working on a web app and an api. I cannot get it running on my Xamarin mobile project. I am using the UWP project to test my configuration since it has the easiest app to troubleshoot on a Windows 10 machine. I am using Visual Studio 2015 Pro.
I am using the Microsoft.Identity.Client 1.1.0-preview.
I used this as my starting point for my attempt to implement.
https://github.com/Azure-Samples/active-directory-b2c-xamarin-native
Right now the project will compile and launch. When I click on Sign in, I get a WebView, but it doesn't look exactly right....
[First Image in Screenshots]
Here are my variables...
public class Constants
{
public static string ApplicationID = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
public static string[] Scopes = {""};
public static string SignUpSignInPolicy = "B2C_1_Standard_SignUpSignIn";
public static string ResetPasswordPolicy = "B2C_1_Standard_PasswordReset";
public static string EditProfilePolicy = "B2C_1_Standard_EditProfile";
public static string Authority = "https://login.microsoftonline.com/[MyTennantName].onmicrosoft.com/B2C_1_Standard_SignUpSignIn";
public static string AuthorityEditProfile = "https://login.microsoftonline.com/[MyTennantName].onmicrosoft.com/B2C_1_Standard_EditProfile";
public static string ApiEndpoint = "https://[MyTennantName].onmicrosoft.com/apiservices";
public static UIParent UiParent = null;
}
My Login method is....
async void OnSignInSignOut(object sender, EventArgs e)
{
try
{
if (btnSignInSignOut.Text == "Sign in")
{
AuthenticationResult ar = await App.PCA.AcquireTokenAsync(Constants.Scopes, GetUserByPolicy(App.PCA.Users, Constants.SignUpSignInPolicy), Constants.UiParent);
UpdateUserInfo(ar);
UpdateSignInState(true);
}
else
{
foreach (var user in App.PCA.Users)
{
App.PCA.Remove(user);
}
UpdateSignInState(false);
}
}
catch (Exception ex)
{
// Checking the exception message
// should ONLY be done for B2C
// reset and not any other error.
if (ex.Message.Contains("AADB2C90118"))
OnPasswordReset();
// Alert if any exception excludig user cancelling sign-in dialog
else if (((ex as MsalException)?.ErrorCode != "authentication_canceled"))
await DisplayAlert($"Exception:", ex.ToString(), "Dismiss");
}
}
However before I can even enter my password I get the following....
[Second image in Screenshots]
My application definition looks like this...[Third image in screenshots]
I don't think it is recognizing my tenant and trying to log me in with a Microsoft account. I have double checked my Tenant name and Application ID.
Screenshots
I don't have enough reputation to post more than one link and one picture.
Also, the Azure AD B2C api application works for a web app. I have created a web app that can authenticate and works with the API.
It looks like while modifying the authorization value in the Sample you removed the /tfp/ part.
You should update your values as follows:
public static string Authority = "https://login.microsoftonline.com/tfp/[MyTennantName].onmicrosoft.com/B2C_1_Standard_SignUpSignIn";
public static string AuthorityEditProfile = "https://login.microsoftonline.com/tfp/[MyTennantName].onmicrosoft.com/B2C_1_Standard_EditProfile";
Is it possible to subscribe to all web requests in windows phone application?
I mean to register a global hook, that will fire every time i make a request to web server. Thanks a lot
Simple example:
// Since the property is static, it will be shared by all instances of WebClientWrapper
// Set this before creating an instance of WebClientWrapper
WebClientWrapper.Hook = address => Debug.WriteLine(address);
var webClientWrapper = new WebClientWrapper();
webClientWrapper.DownloadString("http://www.something.com");
public class WebClientWrapper
{
private readonly WebClient _webClient;
// This can be string, your custom class of whatever you need
public static Action<string> Hook { get; set; }
public WebClientWrapper()
{
_webClient = new WebClient();
}
public string DownloadString(string address)
{
Hook(address);
return _webClient.DownloadString(address);
}
}
My project has a need for realtime user interaction and I think SignalR will solve my need. I'm technically on a SharePoint 2007 project, although I'm exclusively in application pages and thus barely use SharePoint at all. Regardless, I'm stuck in a 2.0 framework app pool in IIS.
My first approach was to try to create a 4.0 application as a sub-site. Unfortunately, that failed miserably. That approach works in a non-SharePoint world, but it appears that SharePoint has hijacked too much of the request pipeline for this approach to work for me.
So now I'm going down the path of creating a separate IIS Site that's 4.0 and using IIS rewrite rules to fake my app into thinking a particular subdirectory (/realtime/) is local and not a separate site so that I don't have to deal with cross domain request issues. The problem is I can't get IIS rewrite rules to rewrite to another http host (e.g. http://www.mySharepoint.com/_layouts/MySite/realtime/Hello.aspx to http://realtime.mySharePoint.com/Hello.aspx).
Any help with approach #1 or approach #2 or any alternative ideas would be greatly appreciated.
Here is what I did... Web App with signalR .net4.0, then your SharePoint Web App .net 2.
Add this to the global.asax in your Signalr project
RouteTable.Routes.MapHttpHandlerRoute("spproxy","spproxy/{*operation}", new SharePointRProxyHandler());
If you want to raise an event from SharePoint you can do a http POST to this new route URL for example
http://localhost:38262/spproxy
It will pass any posted data onto the httphandler below, that will then broadcast it to your clients.
Here is the code for MapHttpHandlerRoute
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace System.Web.Routing
{
public class HttpHandlerRoute : IRouteHandler
{
private String _virtualPath = null;
private IHttpHandler _handler = null;
public HttpHandlerRoute(String virtualPath)
{
_virtualPath = virtualPath;
}
public HttpHandlerRoute(IHttpHandler handler)
{
_handler = handler;
}
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
IHttpHandler result;
if (_handler == null)
{
result = (IHttpHandler)System.Web.Compilation.BuildManager.CreateInstanceFromVirtualPath(_virtualPath, typeof(IHttpHandler));
}
else
{
result = _handler;
}
return result;
}
}
public static class RoutingExtensions
{
public static void MapHttpHandlerRoute(this RouteCollection routes, string routeName, string routeUrl, string physicalFile, RouteValueDictionary defaults = null, RouteValueDictionary constraints = null)
{
var route = new Route(routeUrl, defaults, constraints, new HttpHandlerRoute(physicalFile));
RouteTable.Routes.Add(routeName, route);
}
public static void MapHttpHandlerRoute(this RouteCollection routes, string routeName, string routeUrl, IHttpHandler handler, RouteValueDictionary defaults = null, RouteValueDictionary constraints = null)
{
var route = new Route(routeUrl, defaults, constraints, new HttpHandlerRoute(handler));
RouteTable.Routes.Add(routeName, route);
}
}
}
Or you could just post directly to a httphandler and get the handler to do a connection.Broadcast
namespace SharePointRProxy
{
/// <summary>
/// Summary description for SharePointRProxyHandler
/// </summary>
public class SharePointRProxyHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
IConnectionManager connectonManager = AspNetHost.DependencyResolver.Resolve<IConnectionManager>();
IConnection connection = connectonManager.GetConnection<MyConnection>();
object payload = null; //Add payload here 'context.Request.Params["data"] ?'
JavaScriptSerializer jss = new JavaScriptSerializer();
var payloadJSON = jss.Serialize(payload);
connection.Broadcast(payloadJSON);
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
You could also use either an event handler calling a .net 4.0 web service or an http handler to grab requests from SharePoint and pass them over to a .net 4.0 application running your signalr code.
You can see an example of using an http handler here: http://spmatt.wordpress.com/2012/04/12/harnessing-signalr-in-sharepoint/
I using Visual Studio 2010 (.NET 4). I need to create a COM object (in C#) and have no idea how to get started (what type of project to use,etc.)
OK I found the solution and I'll write it here for the common good.
Start VS2010 as administrator.
Open a class library project (exmaple - MyProject).
Add a new interface to the project (see example below).
Add a using System.Runtime.InteropServices; to the file
Add the attributes InterfaceType, Guid to the interface.
You can generate a Guid using Tools->Generate GUID (option 4).
Add a class that implement the interface.
Add the attributes ClassInterface, Guid, ProgId to the interface.
ProgId convention is {namespace}.{class}
Under the Properties folder in the project in the AssemblyInfo file set ComVisible to true.
In the project properties menu, in the build tab mark "Register for COM interop"
Build the project
now you can use your COM object by using it's ProgID.
example:
the C# code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace Launcher
{
[InterfaceType(ComInterfaceType.InterfaceIsDual), Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX")]
public interface ILauncher
{
void launch();
}
[ClassInterface(ClassInterfaceType.None), Guid("YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYY"), ProgId("Launcher.Launcher")]
public class Launcher : ILauncher
{
private string path = null;
public void launch()
{
Console.WriteLine("I launch scripts for a living.");
}
}
}
and VBScript using the COM:
set obj = createObject("PSLauncher.PSLauncher")
obj.launch()
and the output will be:
I launch scripts for a living
Creation Steps
Start Visual Studio 2013 as administrator
Install Visual Studio extension Microsoft Visual Studio Installer Projects
Create a class library project (WinFormActivex)
Create your example window form (MainWindow)
Create a new component interface(ILauncher)
Create a new security interface (IObjectSafety)
Create the component control (Launcher) that implement interfaces and launch the window.
Check that all GUIDs are generated by you
Check that the project is marked for COM
Create the setup project (LauncherInstaller) with the primary output of WinFormActivex with the property Register = vsdrpCOM
Install LauncherInstaller
Run your test page in explorer (test.html)
MainWindow
You can create a normal Form, here is pre-generated.
public partial class MainWindow : Form
{
public MainWindow()
{
InitializeComponent();

{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

You could use a class library project. Declare a type with methods that will be exposed as a COM object.
Make sure that the assembly has been made COM-visible:
And finally register it using regasm.exe:
regasm.exe /codebase mylib.dll
Now the assembly is exposed as a COM object and the type you declared can be consumed by any client that supports COM.
