Duplicate content appearing for multi lingual sites

- by Rocky Singh

I have a site which has a default url say "http://www.blahblah.com/" (which is default in english language). In my site there is support for multi languages. I am having few links at my home page say "English" "French" "Spanish" etc. and on clicking these links user is redirected to these links: http://www.blahblah.com/en-us/ (English) http://www.blahblah.com/fr-ca/ (French) http://www.blahblah.com/spanish-culture/ (Spanish) and based on culture in the url I am showing the content accordingly to end users in their desired language. Now, this was how my site is. The issue I am getting is with SEO. I noticed Google is considering (I checked via Google web masters) my site pages as duplicate like: 1. http://www.blahblah.com/documents/ and http://www.blahblah.com/en-us/documents/ 2. http://www.blahblah.com/news/ and http://www.blahblah.com/en-us/news and similarly all the pages are considered as a duplicate content in Google webmasters tools. I am worried of this, since I think my site is getting penalized in ranking because of this. Could you drop some idea how to overcome this situation?

ASP.NET website deployment [on hold]

- by Rei Brazilva

I am getting my hands wet with ASP and I have been following the tutorials. I deployed the site and in Azure and it worked great. Today I started actually designing the site. And when I published, it looks as if it doesn't read any of the files I just updated, added, and modified. It works on my localhost, but not in the Azure. I thought when you publish, everything goes up, including the new files. I don't have enough reputation to add a picture so, you'll forgive me. SO, basically, how do I get my entire site uploaded? In case anyone does stop by, I was able to pull this out just recently: CA0058 Error Running Code Analysis CA0058 : The referenced assembly 'DotNetOpenAuth.AspNet, Version=4.0.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246' could not be found.

Banshee crashes consistently - is there a fix?

- by user36334

Since updating to ubuntu 11.10 I've had trouble with banshee. In particular when I run it I find that it crashes within an hour without fail. I get the following Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object at Mono.Zeroconf.Providers.AvahiDBus.BrowseService.DisposeResolver () [0x00000] in <filename unknown>:0 at Mono.Zeroconf.Providers.AvahiDBus.BrowseService.Dispose () [0x00000] in <filename unknown>:0 at Mono.Zeroconf.Providers.AvahiDBus.ServiceBrowser.OnItemRemove (Int32 interface, Protocol protocol, System.String name, System.String type, System.String domain, LookupResultFlags flags) [0x00000] in <filename unknown>:0 at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (System.Reflection.MonoMethod,object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 --- End of inner exception stack trace --- at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 at System.Reflection.MethodBase.Invoke (System.Object obj, System.Object[] parameters) [0x00000] in <filename unknown>:0 at System.Delegate.DynamicInvokeImpl (System.Object[] args) [0x00000] in <filename unknown>:0 at System.MulticastDelegate.DynamicInvokeImpl (System.Object[] args) [0x00000] in <filename unknown>:0 at System.Delegate.DynamicInvoke (System.Object[] args) [0x00000] in <filename unknown>:0 at NDesk.DBus.Connection.HandleSignal (NDesk.DBus.Message msg) [0x00000] in <filename unknown>:0 at NDesk.DBus.Connection.DispatchSignals () [0x00000] in <filename unknown>:0 at NDesk.DBus.Connection.Iterate () [0x00000] in <filename unknown>:0 at Mono.Zeroconf.Providers.AvahiDBus.DBusManager.IterateThread (System.Object o) [0x00000] in <filename unknown>:0 Does anyone else also have this problem?

Explicitly pass context object versus injecting with IoC

- by SonOfPirate

I have a layered service application where the service layer delegates operations into the domain layer for execution. Many of these operations need to know the context under which they are operation. (The context included the identity of the current user, culture information, etc. received from the caller.) For example, I have an API method that returns a list of announcements. The list is based on the current user's role and each announcement is localized to their culture. The API is a thin-facade that delegates to an Application Service in my domain layer. The Application Service method obviously needs to know the context of the current request/operation as another call to the same API from another user should result in a different list. Within this method, we also have logging that uses some of the context information so we a clear understanding of the context when the operation was performed (this is especially useful if something goes wrong.) While this is a contrived example, in the real world, my Application Services will coordinate operations with many collaborative components, any number of them also needing the context information. My choice is to pass the context to the Application Service which would then pass it with any calls to collaborators or have the IoC container satisfy the dependency the Application Service and any collaborators have on the context. I am wondering if it is considered good/bad, best practices/code smell, etc. if I pass the context object as a parameter to the domain methods or if injecting the context via an IoC container is preferred. (EDIT: I should mention that the context object is instantiated per-request.)

Enterprise Instrumentation: The 'sessionName' parameter of value 'TraceSession' is not valid

- by Michael Freidgeim

We are still using Enterprise Instrumentation(that was created during .Net 1.1 time)In new Server 2008 environment and IIS 7 we have the following errors:The 'sessionName' parameter of value 'TraceSession' is not valid. A trace session of this name does not exist in the TraceSessions configuration file for Windows Trace Session Manager service. Ensure that a session of this name exists in the TraceSessions configuration file and that the Windows Trace Session Manager service is started. at Microsoft.EnterpriseInstrumentation.EventSinks.TraceEventSink..ctor(IDictionary parameters, EventSource eventSource) --- End of inner exception stack trace --- at System.RuntimeMethodHandle._InvokeConstructor(IRuntimeMethodInfo method, Object[] args, SignatureStruct& signature, RuntimeType declaringType) at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at Microsoft.EnterpriseInstrumentation.EventSinks.EventSink.CreateNewEventSinks(DataRow[] eventSinkRows, EventSource eventSource)I’ve seen the same errors on development Win7 machines when using IIS.

Is it possible to use a VB master page to cover an entirely separate directory written in C#?

- by Jason Weber

I have a company website written in vb.net. There are 5 master pages. I recently began utilizing a forum application, also asp.net 4.0, but this one is written in C#. My forum directory is domain.com/knowledgebase/. Is there any possible way to take one of my vb.net master pages and somehow integrate into the /knowledgebase/ directory? Here's what's currently This is what's in the top of every page in my site: <%@ Page Title="USS Vision Inc." Language="VB" MasterPageFile="~/homepage.master" AutoEventWireup="false" CodeFile="default.aspx.vb" Inherits="_default" culture="auto" meta:resourcekey="PageResource1" uiculture="auto" Debug="true" %> This is what's in my /knowledgebase/ directory: <%@ Page Language="C#" AutoEventWireup="true" ValidateRequest="false" Inherits="YAF.ForumPageBase" culture="auto" uiculture="auto" %> <%@ Register TagPrefix="YAF" Assembly="YAF" Namespace="YAF" %> <script runat="server"> Is it somehow possible to use, for instance, homepage.master in the /knowledgebase/ directory? If so, how would I accomplish this? Thanks for any guidance anybody can offer!

My application had a WindowsIdentity crisis

- by Brian Donahue

The project I have been working on this week to test computer environments needs to do various actions as a user other than the one running the application. For instance, it looks up an installed Windows Service, finds out who the startup user is, and tries to connect to a database as that Windows user. Later on, it will need to access a file in the context of the currently logged-in user. With ASP .NET, this is super-easy: just go into Web.Config and set up the "identity impersonate" node, which can either impersonate a named user or the one who had logged into the website if authentication was enabled. With Windows applications, this is not so straightforward. There may be something I am overlooking, but the limitation seems to be that you can only change the security context on the current thread: any threads spawned by the impersonated thread also inherit the impersonated credentials. Impersonation is easy enough to do, once you figure out how. Here is my code for impersonating a user on the current thread: using System; using System.ComponentModel; using System.Runtime.InteropServices; using System.Security.Principal; public class ImpersonateUser { IntPtr userHandle; [DllImport("advapi32.dll", SetLastError = true)] static extern bool LogonUser( string lpszUsername, string lpszDomain, string lpszPassword, LogonType dwLogonType, LogonProvider dwLogonProvider, out IntPtr phToken ); [DllImport("kernel32.dll", SetLastError = true)] static extern bool CloseHandle(IntPtr hHandle); enum LogonType : int { Interactive = 2, Network = 3, Batch = 4, Service = 5, NetworkCleartext = 8, NewCredentials = 9, } enum LogonProvider : int { Default = 0, } public static WindowsImpersonationContext Impersonate(string user, string domain, string password) { IntPtr userHandle = IntPtr.Zero; bool loggedOn = LogonUser( user, domain, password, LogonType.Interactive, LogonProvider.Default, out userHandle); if (!loggedOn) throw new Win32Exception(Marshal.GetLastWin32Error()); WindowsIdentity identity = new WindowsIdentity(userHandle); WindowsPrincipal principal = new WindowsPrincipal(identity); System.Threading.Thread.CurrentPrincipal = principal; return identity.Impersonate(); } } /* Call impersonation */ ImpersonateUser.Impersonate("UserName","DomainName","Password"); /* When you want to go back to the original user */ WindowsIdentity.Impersonate(IntPtr.Zero); When you want to stop impersonating, you can call Impersonate() again with a null pointer. This will allow you to simulate a variety of different Windows users from the same applicaiton.

This task is currently locked by a running workflow and cannot be edited. Limitation to both Nintex and SPD workflow

- by ybbest

Note, this post is from Nintex Forum here. These limitations apply to both SharePoint designer Workflow and Nintex Workflow as Nintex using the SharePoint workflow engine. The common cause that I experience is that ‘parent’ workflow is generating more than one task at once. This is common as you can have multiple approvers for certain approval process. You could also have workflow running when the task is created, one of the common scenario is you would like to set a custom column value in your approval task. For me this is huge limitation, as Nintex lover I really hope Nintex could solve this problem with Microsoft going forward. Introduction “This task is currently locked by a running workflow and cannot be edited” is a common message that is seen when an error occurs while the SharePoint workflow engine is processing a task item associated with a workflow. When a workflow processes a task normally, the following sequence of events is expected to occur: 1. The process begins. 2. The workflow places a ‘lock’ on the task so nothing else can change the values while the workflow is processing. 3. The workflow processes the task. 4. The lock is released when the task processing is finished. When the message is encountered, it usually indicates that an error occurred between step 2 and 4. As a result, the lock is never released. Therefore, the ‘task locked’ message is not an error itself, rather a symptom of another error – the ‘task locked’ message does not indicate what went wrong. In most cases, once this message is encountered, the workflow cannot be made to continue and must be terminated and started again. The following is a guide that can help troubleshoot the cause of these messages. Some initial observations to narrow down the potential causes are: Is the error consistent or intermittent? When the error is consistent, it will happen every time the workflow is run. When it is intermittent, it may happen regularly, but not every time. Does the error occur the first time the user tries to respond to a task, or do they respond and notice the workflow does not continue, and when they respond again the error occurs? If the message is present when the user first responds to the task, the issue would have occurred when the task was created. Otherwise, it would have occurred when the user attempted to respond to the task. Causes Modifying the task list A cause of this error appearing consistently the first time a user tries to respond to a task is a modification to the default task list schema. For example, changing the ‘Assigned to’ field in a task list to be a multiple selection will cause the behaviour. Deleting the workflow task then restoring it from the Recycle bin If you start a workflow, delete the workflow task then restore it from the Recycle Bin in SharePoint, the workflow will fail with the ‘task locked’ error. This is confirmed behaviour whether using a SharePoint Designer or a Nintex workflow. You will need to terminate the workflow and start it again. Parallel simultaneous responses A cause of this error appearing inconsistently is multiple users responding to tasks in parallel at the same time. In this scenario, one task will complete correctly and the other will not process. When the user tries again, the ‘task locked’ message will display. Nintex included a workaround for this issue in build 11000. In build 11000 and later, one of the users will receive a message on the task form when they attempt to respond, stating that they need to try again in a few moments. Additional processing on the task A cause of this error appearing consistently and inconsistently is having an additional system running on the items in the task list. Some examples include: a workflow running on the task list, an event receiver running on the task list or another automated process querying and updating workflow tasks. Note: This Microsoft help article (http://office.microsoft.com/en-us/sharepointdesigner/HA102376561033.aspx#5) explains creating a workflow that runs on the task list to update a field on the task. Our experience shows that this causes the ‘Task Locked’ issues when the ‘parent’ workflow is generating more than one task at once. Isolated system error If the error is a rare event, or a ‘one off’ event, then an isolated system error may have occurred. For example, if there is a database connectivity issue while the workflow is processing the task response, the task will lock. In this case, the user will respond to a task but the workflow will not continue. When they respond again, the ‘task locked’ message will display. In this case, there will be an error in the SharePoint ULS Logs at the time that the user originally responded. Temporary delay while workflow processes If the workflow is taking a long time to process after a user submits a task, they may notice and try to respond to the task again. They will see the task locked error, but after a number of attempts (or after waiting some time) the task response page eventually indicates the task has been responded to. In this case, nothing actually went wrong, and the error message gives an accurate indication of what is happening – the workflow temporarily locked the task while it was processing. This scenario may occur in a very large workflow, or after the SharePoint application pool has just started. Modifying the task via a web service with an invalid url If the Nintex Workflow web service is used to respond to or delegate a task, the site context part of the url must be a valid alternative access mapping url. For example, if you access the web service via the IP address of the SharePoint server, and the IP address is not a valid AAM, the task can become locked. The workflow has become stuck without any apparent errors This behaviour can occur as a result of a bug in the SharePoint 2010 workflow engine. If you do not have the August 2010 Cumulative Update (or later) for SharePoint, and your workflow uses delays, “Flexi-task”, State machine”, “Task Reminder” actions or variables, you could be affected. Check the SharePoint 2010 Updates site here: http://technet.microsoft.com/en-us/sharepoint/ff800847. The October CU is recommended http://support.microsoft.com/kb/2553031. The fix is described as “Consider the following scenario. You add a Delay activity to a workflow. Then, you set the duration for the Delay activity. You deploy the workflow in SharePoint Foundation 2010. In this scenario, the workflow is not resumed after the duration of the Delay activity”. If you find this is occurring in your environment, install the October CU, terminate all the running workflows affected and run them afresh. Investigative steps The first step to isolate the issue is to create a new task list on the site and configure the workflow to use it. Any customizations that were made to the original task list should not be made to the new task list. If the new task list eliminates the issue, then the cause can be attributed to the original task list or a change that was made to it. To change the task list that the workflow uses: In Workflow Designer select Settings -> Startup Options Then configure the task list as required If any of the scenarios above do not help, check the SharePoint logs for any messages with a category of ‘Workflow Infrastructure’. Conclusion The information in this article has been gathered from observations and investigations by Nintex. The sources of these issues are the underlying SharePoint workflow engine. This article will be updated if further causes are discovered. From <http://connect.nintex.com/forums/thread/6503.aspx>

Use ASP.NET 4 Browser Definitions with ASP.NET 3.5

- by Stephen Walther

We updated the browser definitions files included with ASP.NET 4 to include information on recent browsers and devices such as Google Chrome and the iPhone. You can use these browser definition files with earlier versions of ASP.NET such as ASP.NET 3.5. The updated browser definition files, and instructions for installing them, can be found here: http://aspnet.codeplex.com/releases/view/41420 The changes in the browser definition files can cause backwards compatibility issues when you upgrade an ASP.NET 3.5 web application to ASP.NET 4. If you encounter compatibility issues, you can install the old browser definition files in your ASP.NET 4 application. The old browser definition files are included in the download file referenced above. What’s New in the ASP.NET 4 Browser Definition Files The complete set of browsers supported by the new ASP.NET 4 browser definition files is represented by the following figure: If you look carefully at the figure, you’ll notice that we added browser definitions for several types of recent browsers such as Internet Explorer 8, Firefox 3.5, Google Chrome, Opera 10, and Safari 4. Furthermore, notice that we now include browser definitions for several of the most popular mobile devices: BlackBerry, IPhone, IPod, and Windows Mobile (IEMobile). The mobile devices appear in the figure with a purple background color. To improve performance, we removed a whole lot of outdated browser definitions for old cell phones and mobile devices. We also cleaned up the information contained in the browser files. Here are some of the browser features that you can detect: Are you a mobile device? <%=Request.Browser.IsMobileDevice %> Are you an IPhone? <%=Request.Browser.MobileDeviceModel == "IPhone" %> What version of JavaScript do you support? <%=Request.Browser["javascriptversion"] %> What layout engine do you use? <%=Request.Browser["layoutEngine"] %> Here’s what you would get if you displayed the value of these properties using Internet Explorer 8: Here’s what you get when you use Google Chrome: Testing Browser Settings When working with browser definition files, it is useful to have some way to test the capability information returned when you request a page with different browsers. You can use the following method to return the HttpBrowserCapabilities the corresponds to a particular user agent string and set of browser headers: public HttpBrowserCapabilities GetBrowserCapabilities(string userAgent, NameValueCollection headers) { HttpBrowserCapabilities browserCaps = new HttpBrowserCapabilities(); Hashtable hashtable = new Hashtable(180, StringComparer.OrdinalIgnoreCase); hashtable[string.Empty] = userAgent; // The actual method uses client target browserCaps.Capabilities = hashtable; var capsFactory = new System.Web.Configuration.BrowserCapabilitiesFactory(); capsFactory.ConfigureBrowserCapabilities(headers, browserCaps); capsFactory.ConfigureCustomCapabilities(headers, browserCaps); return browserCaps; } At the end of this blog entry, there is a link to download a simple Visual Studio 2008 project – named Browser Definition Test -- that uses this method to display capability information for arbitrary user agent strings. For example, if you enter the user agent string for an iPhone then you get the results in the following figure: The Browser Definition Test application enables you to submit a user-agent string and display a table of browser capabilities information. The browser definition files contain sample user-agent strings for each browser definition. I got the iPhone user-agent string from the comments in the iphone.browser file. Enumerating Browser Definitions Someone asked in the comments whether or not there is a way to enumerate all of the browser definitions. You can do this if you ware willing to use a little reflection and read a private property. The browser definition files in the config\browsers folder get parsed into a class named BrowserCapabilitesFactory. After you run the aspnet_regbrowsers tool, you can see the source for this class in the config\browser folder by opening a file named BrowserCapsFactory.cs. The BrowserCapabilitiesFactoryBase class has a protected property named BrowserElements that represents a Hashtable of all of the browser definitions. Here's how you can read this protected property and display the ID for all of the browser definitions: var propInfo = typeof(BrowserCapabilitiesFactory).GetProperty("BrowserElements", BindingFlags.NonPublic | BindingFlags.Instance); Hashtable browserDefinitions = (Hashtable)propInfo.GetValue(new BrowserCapabilitiesFactory(), null); foreach (var key in browserDefinitions.Keys) { Response.Write("" + key); } If you run this code using Visual Studio 2008 then you get the following results: You get a huge number of outdated browsers and devices. In all, 449 browser definitions are listed. If you run this code using Visual Studio 2010 then you get the following results: In the case of Visual Studio 2010, all the old browsers and devices have been removed and you get only 19 browser definitions. Conclusion The updated browser definition files included in ASP.NET 4 provide more accurate information for recent browsers and devices. If you would like to test the new browser definitions with different user-agent strings then I recommend that you download the Browser Definition Test project: Browser Definition Test Project

Adding A Custom Dropdown in RCDC for Forefront Identity Manager 2010

- by Daniel Lackey

My latest exploration has been FIM 2010 for Identity Management. The following is a post of how to add a custom dropdown for the FIM Portal. I have decided to document this as I cannot find documentation on how to do this anywhere else. I hope that it finds useful to others. For starters, this was to me not an easy task to figure out. I really would like to know why it is so cumbersome to do something that seems like a lot of people would need to do, but that’s for another day J The dropdown I wanted to add was for ‘Account Status’ which would display if the account is ‘Enabled’ or ‘Disabled’ in the data source Active Directory. This option would also allow helpdesk users or admins to administer the userAccountControl attribute in AD from the FIM Portal interface. The first thing I had to do was create the attribute itself. This is done by going to Administration à Schema Management from the FIM 2010 portal. Once here, you click on All Attributes. What is listed here are all attributes and their associated Resource Types in FIM. To create the ‘AccountStatus’ attribute, click on New. As shown below, enter ‘AccountStatus’ with no spaces for the System Name and ‘Account Status’ for the Display Name. The Data Type is going to be ‘Indexed String’. Click Next. Leave everything on the Localization tab default and click Next. On the Validation tab as shown below, we will enter the regex expression ^(Enabled|Disabled)?$ with our two desired string values ‘Enabled’ and ‘Disabled’. Click on Finish and then and Submit to complete adding the attribute. The next step involves associating the attribute with a resource type. This is called ‘Binding’ the attribute. From the Schema Management page, click on All Bindings. From the page that comes up, click on New. As shown below, enter ‘User’ for the Resource Type and ‘Account Status’ for the Attribute Type. This is essentially binding the Account Status attribute to the ‘User’ Resource Type. Click Next. On the ‘Attribute Override’ tab, type in ‘Account Status’ for the Display Name field. Click Next. On the ‘Localization’ tab, click Next. On the ‘Validation’ tab, enter the regex expression ^(Enabled|Disabled)?$ we entered previously for the attribute. Click Finish and then Submit to complete. Now that the Attribute and the Binding are complete, you have to give users permission to see the attribute on the User Edit page. Go to Administration à Management Policy Rules. Look for the rule named Administration: Administrators can read and update Users and click on it. Once it opens, click on the ‘Target Resources’ tab and look at the section named Resource Attributes. Type in at the end the ‘Account Status’ attribute and check it with the validator. Once done click on OK to save the changes. Lastly, we need to add the actual dropdown control to the RCDC (Resource Control Display Configuration) for User Editing. Go to Administration à Resource Control Display Configuration. From here navigate until you find the RCDC named Configuration for User Editing RCDC and click on it. The following is what you will see: First step is to export the Configuration Data file. Click on the Export configuration link and save the file to your desktop of other folder. Find the file you just exported and open the file in your XML editor of choice. I use notepad but anything will work. Since we are adding a dropdown control, first find another control in the existing file that is already a dropdown in FIM. I used EmployeeType as my example. Copy the control from the beginning tag named <my:Control… to the ending tag </my:Control>. Now take what you copied and paste it in whatever location you desire within the form between two other controls. I chose to place the ‘Account Status’ field after the ‘Account Name’ field. After you paste the control you will need to modify so it looks like this: Notice where you specify what attribute you are dealing with where it has AccountStatus in the XML. Once you are complete with modifying this, save the file and make sure it is a .xml file. Now go back to the Configuration for User Editing screen and look at the section named ‘Configuration Data’. Click the ‘Browse’ button and find the XML file you just modified and choose it. Click OK on the bottom of the window and you are done! Now when you click on a user’s name in the FIM Portal, you should see the newly added dropdown box as below: Later I will post more about this drop down, specifically on how to automate actually ‘Disabling’ the account in the data source through the FIM Workflows and MAs. <my:Control my:Name="AccountStatus" my:TypeName="UocDropDownList" my:Caption="{Binding Source=schema, Path=AccountStatus.DisplayName}" my:Description="{Binding Source=schema, Path=AccountStatus.Description}" my:RightsLevel="{Binding Source=rights, Path=AccountStatus}"> <my:Properties> <my:Property my:Name="ValuePath" my:Value="Value"/> <my:Property my:Name="CaptionPath" my:Value="Caption"/> <my:Property my:Name="HintPath" my:Value="Hint"/> <my:Property my:Name="ItemSource" my:Value="{Binding Source=schema, Path=AccountStatus.LocalizedAllowedValues}"/> <my:Property my:Name="SelectedValue" my:Value="{Binding Source=object, Path=AccountStatus, Mode=TwoWay}"/> </my:Properties> </my:Control>

Android: How to bind spinner to custom object list?

- by niko

Hi, In the user interface there has to be a spinner which contains some names (the names are visible) and each name has its own ID (the IDs are not equal to display sequence). When the user selects the name from the list the variable currentID has to be changed. The application contains the ArrayList Where User is an object with ID and name: public class User{ public int ID; public String name; } What I don't know is how to create a spinner which displays the list of user's names and bind spinner items to IDs so when the spinner item is selected/changed the variable currentID is set to appropriate value. I would appreciate if anyone could show the solution of the described problem or provide any link useful to solve the problem. Thanks!

Enabling Kerberos Authentication for Reporting Services

- by robcarrol

Recently, I’ve helped several customers with Kerberos authentication problems with Reporting Services and Analysis Services, so I’ve decided to write this blog post and pull together some useful resources in one place (there are 2 whitepapers in particular that I found invaluable configuring Kerberos authentication, and these can be found in the references section at the bottom of this post). In most of these cases, the problem has manifested itself with the Login failed for User ‘NT Authority\Anonymous’ (“double-hop”) error. By default, Reporting Services uses Windows Integrated Authentication, which includes the Kerberos and NTLM protocols for network authentication. Additionally, Windows Integrated Authentication includes the negotiate security header, which prompts the client to select Kerberos or NTLM for authentication. The client can access reports which have the appropriate permissions by using Kerberos for authentication. Servers that use Kerberos authentication can impersonate those clients and use their security context to access network resources. You can configure Reporting Services to use both Kerberos and NTLM authentication; however this may lead to a failure to authenticate. With negotiate, if Kerberos cannot be used, the authentication method will default to NTLM. When negotiate is enabled, the Kerberos protocol is always used except when: Clients/servers that are involved in the authentication process cannot use Kerberos. The client does not provide the information necessary to use Kerberos. An in-depth discussion of Kerberos authentication is beyond the scope of this post, however when users execute reports that are configured to use Windows Integrated Authentication, their logon credentials are passed from the report server to the server hosting the data source. Delegation needs to be set on the report server and Service Principle Names (SPNs) set for the relevant services. When a user processes a report, the request must go through a Web server on its way to a database server for processing. Kerberos authentication enables the Web server to request a service ticket from the domain controller; impersonate the client when passing the request to the database server; and then restrict the request based on the user’s permissions. Each time a server is required to pass the request to another server, the same process must be used. Kerberos authentication is supported in both native and SharePoint integrated mode, but I’ll focus on native mode for the purpose of this post (I’ll explain configuring SharePoint integrated mode and Kerberos authentication in a future post). Configuring Kerberos avoids the authentication failures due to double-hop issues. These double-hop errors occur when a users windows domain credentials can’t be passed to another server to complete the user’s request. In the case of my customers, users were executing Reporting Services reports that were configured to query Analysis Services cubes on a separate machine using Windows Integrated security. The double-hop issue occurs as NTLM credentials are valid for only one network hop, subsequent hops result in anonymous authentication. The client attempts to connect to the report server by making a request from a browser (or some other application), and the connection process begins with authentication. With NTLM authentication, client credentials are presented to Computer 2. However Computer 2 can’t use the same credentials to access Computer 3 (so we get the Anonymous login error). To access Computer 3 it is necessary to configure the connection string with stored credentials, which is what a number of customers I have worked with have done to workaround the double-hop authentication error. However, to get the benefits of Windows Integrated security, a better solution is to enable Kerberos authentication. Again, the connection process begins with authentication. With Kerberos authentication, the client and the server must demonstrate to one another that they are genuine, at which point authentication is successful and a secure client/server session is established. In the illustration above, the tiers represent the following: Client tier (computer 1): The client computer from which an application makes a request. Middle tier (computer 2): The Web server or farm where the client’s request is directed. Both the SharePoint and Reporting Services server(s) comprise the middle tier (but we’re only concentrating on native deployments just now). Back end tier (computer 3): The Database/Analysis Services server/Cluster where the requested data is stored. In order to enable Kerberos authentication for Reporting Services it’s necessary to configure the relevant SPNs, configure trust for delegation for server accounts, configure Kerberos with full delegation and configure the authentication types for Reporting Services. Service Principle Names (SPNs) are unique identifiers for services and identify the account’s type of service. If an SPN is not configured for a service, a client account will be unable to authenticate to the servers using Kerberos. You need to be a domain administrator to add an SPN, which can be added using the SetSPN utility. For Reporting Services in native mode, the following SPNs need to be registered --SQL Server Service SETSPN -S mssqlsvc/servername:1433 Domain\SQL For named instances, or if the default instance is running under a different port, then the specific port number should be used. --Reporting Services Service SETSPN -S http/servername Domain\SSRS SETSPN -S http/servername.domain.com Domain\SSRS The SPN should be set for the NETBIOS name of the server and the FQDN. If you access the reports using a host header or DNS alias, then that should also be registered SETSPN -S http/www.reports.com Domain\SSRS --Analysis Services Service SETSPN -S msolapsvc.3/servername Domain\SSAS Next, you need to configure trust for delegation, which refers to enabling a computer to impersonate an authenticated user to services on another computer: Location Description Client 1. The requesting application must support the Kerberos authentication protocol. 2. The user account making the request must be configured on the domain controller. Confirm that the following option is not selected: Account is sensitive and cannot be delegated. Servers 1. The service accounts must be trusted for delegation on the domain controller. 2. The service accounts must have SPNs registered on the domain controller. If the service account is a domain user account, the domain administrator must register the SPNs. In Active Directory Users and Computers, verify that the domain user accounts used to access reports have been configured for delegation (the ‘Account is sensitive and cannot be delegated’ option should not be selected): We then need to configure the Reporting Services service account and computer to use Kerberos with full delegation: We also need to do the same for the SQL Server or Analysis Services service accounts and computers (depending on what type of data source you are connecting to in your reports). Finally, and this is the part that sometimes gets over-looked, we need to configure the authentication type correctly for reporting services to use Kerberos authentication. This is configured in the Authentication section of the RSReportServer.config file on the report server. <Authentication> <AuthenticationTypes> <RSWindowsNegotiate/> </AuthenticationTypes> <EnableAuthPersistence>true</EnableAuthPersistence> </Authentication> This will enable Kerberos authentication for Internet Explorer.

Intermittent Could not load file or assembly / PolicyExceptions

Intermittently we'll get errors like these from our .NET 3.5 web applications: Exception: System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'itextsharp, Version=4.1.2.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca' or one of its dependencies.

The problem only occurs on the first two that are running 2008 non R2. Running depends.exe on all three servers gives equal results for the nonR2 servers: My DLL is shown as x86 (compiled as AnyCPU, running in x64 w3wp), all other modules show as x64. Missing IESHIMS.DLL and LINKINFO.DLL - both of these seem to be red herrings according to Google. The third server shows the same, except it does not miss LINKINFO.DLL All servers are running IIS7 (7.5 for the R2 one) under a custom domain account that has been granted the necessary permissions: aspnet_regiis -ga [user] Load user profile is set to false on all three servers. I've tried setting this to true on one of the faulting servers, according to: http://stackoverflow.com/questions/1846816/iis7-failed-to-grant-minimum-permission-requests By running processmonitor I can see that it's now using the C:\Users\TEMP\AppData\Local\Temp directory for various temp files - the other ones are not using any such directory. So far I'll let it run in this way to see if this changes anything. I'm in doubt however given that the third server is not exhibiting the problems, yet still has "Load user profile" set to the same value, false. I've also tried running Fuslogvw on all three servers, logging binding failures to disk. All three servers report the same binding errors for VJSharpCodeProvider and CppCodeProvider, but these seem to be normal as well and can be solved by not defining the DEBUG and TRACE constants during build. We're running about 500 websites on each server (identical, load balanced), of which 50 are under moderate load, the problem has arisen both under heavy load as well as under minimal load however. Right now I'm waiting for the errors to happen again so I can hopefully see a pattern and determine whether "Load user profile" alleviates the issue. Any suggestions in the meantime would be very welcome! Also, I don't understand how the lack of "Load user profile" would cause an issue like this? And even further, how it would seemingly work on R2 but not on plain 2008? Thanks!

C# HttpListener without using netsh to register a URI

- by Chris T

My application uses a small webserver to server up some files and have a web interface for administration remotely. Right now the user has to use netsh to register the URI like so netsh http add urlacl url=http://+:1233/ user=Chris-PC\Chris Which is no fun for the average user. I'd like the program to be able to listen on any port specified by the user from my program without the end-user needing to using command prompt. Is there anyway to accomplish this short of just using Process.Start and running command prompt myself?

Interesting articles and blogs on SPARC T4

- by mv

Interesting articles and blogs on SPARC T4 processor I have consolidated all the interesting information I could get on SPARC T4 processor and its hardware cryptographic capabilities. Hope its useful. 1. Advantages of SPARC T4 processor Most important points in this T4 announcement are : "The SPARC T4 processor was designed from the ground up for high speed security and has a cryptographic stream processing unit (SPU) integrated directly into each processor core. These accelerators support 16 industry standard security ciphers and enable high speed encryption at rates 3 to 5 times that of competing processors. By integrating encryption capabilities directly inside the instruction pipeline, the SPARC T4 processor eliminates the performance and cost barriers typically associated with secure computing and makes it possible to deliver high security levels without impacting the user experience." Data Sheet has more details on these : "New on-chip Encryption Instruction Accelerators with direct non-privileged support for 16 industry-standard cryptographic algorithms plus random number generation in each of the eight cores: AES, Camellia, CRC32c, DES, 3DES, DH, DSA, ECC, Kasumi, MD5, RSA, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512" I ran "isainfo -v" command on Solaris 11 Sparc T4-1 system. It shows the new instructions as expected : $ isainfo -v 64-bit sparcv9 applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc 32-bit sparc applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc v8plus div32 mul32 2. Dan Anderson's Blog have some interesting points about how these can be used : "New T4 crypto instructions include: aes_kexpand0, aes_kexpand1, aes_kexpand2, aes_eround01, aes_eround23, aes_eround01_l, aes_eround_23_l, aes_dround01, aes_dround23, aes_dround01_l, aes_dround_23_l. Having SPARC T4 hardware crypto instructions is all well and good, but how do we access it ? The software is available with Solaris 11 and is used automatically if you are running Solaris a SPARC T4. It is used internally in the kernel through kernel crypto modules. It is available in user space through the PKCS#11 library." 3. Dans' Blog on Where's the Crypto Libraries? Although this was written in 2009 but still is very useful "Here's a brief tour of the major crypto libraries shown in the digraph: The libpkcs11 library contains the PKCS#11 API (C_\*() functions, such as C_Initialize()). That in turn calls library pkcs11_softtoken or pkcs11_kernel, for userland or kernel crypto providers. The latter is used mostly for hardware-assisted cryptography (such as n2cp for Niagara2 SPARC processors), as that is performed more efficiently in kernel space with the "kCF" module (Kernel Crypto Framework). Additionally, for Solaris 10, strong crypto algorithms were split off in separate libraries, pkcs11_softtoken_extra libcryptoutil contains low-level utility functions to help implement cryptography. libsoftcrypto (OpenSolaris and Solaris Nevada only) implements several symmetric-key crypto algorithms in software, such as AES, RC4, and DES3, and the bignum library (used for RSA). libmd implements MD5, SHA, and SHA2 message digest algorithms" 4. Difference in T3 and T4 Diagram in this blog is good and self explanatory. Jeff's blog also highlights the differences "The T4 servers have improved crypto acceleration, described at https://blogs.oracle.com/DanX/entry/sparc_t4_openssl_engine. It is "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". Every physical or virtual CPU on a SPARC-T4 has full access to hardware based crypto acceleration at all times. .... For completeness sake, it's worth noting that the T4 adds more crypto algorithms, and accelerates Camelia, CRC32c, and more SHA-x." 5. About performance counters In this blog, performance counters are explained : "Note that unlike T3 and before, T4 crypto doesn't require kernel modules like ncp or n2cp, there is no visibility of crypto hardware with kstats or cryptoadm. T4 does provide hardware counters for crypto operations. You can see these using cpustat: cpustat -c pic0=Instr_FGU_crypto 5 You can check the general crypto support of the hardware and OS with the command "isainfo -v". Since T4 crypto's implementation now allows direct userland access, there are no "crypto units" visible to cryptoadm. " For more details refer Martin's blog as well. 6. How to turn off SPARC T4 or Intel AES-NI crypto acceleration I found this interesting blog from Darren about how to turn off SPARC T4 or Intel AES-NI crypto acceleration. "One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine. The alternate to this is having the application coded to call getisax(2) system call and make the choice itself. We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so and libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run. To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present. This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly. For SPARC T4 : export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" .. For Intel systems with AES-NI support: export LD_HWCAP="-aes"" Note that LD_HWCAP is explained in http://docs.oracle.com/cd/E23823_01/html/816-5165/ld.so.1-1.html "LD_HWCAP, LD_HWCAP_32, and LD_HWCAP_64 - Identifies an alternative hardware capabilities value... A “-” prefix results in the capabilities that follow being removed from the alternative capabilities." 7. Whitepaper on SPARC T4 Servers—Optimized for End-to-End Data Center Computing This Whitepaper on SPARC T4 Servers—Optimized for End-to-End Data Center Computing explains more details. It has DTrace scripts which may come in handy : "To ensure the hardware-assisted cryptographic acceleration is configured to use and working with the security scenarios, it is recommended to use the following Solaris DTrace script. #!/usr/sbin/dtrace -s pid$1:libsoftcrypto:yf*:entry, pid$target:libsoftcrypto:rsa*:entry, pid$1:libmd:yf*:entry { @[probefunc] = count(); } tick-1sec { printa(@ops); trunc(@ops); }" Note that I have slightly modified the D Script to have RSA "libsoftcrypto:rsa*:entry" as well as per recommendations from Chi-Chang Lin. 8.

Changing how a telerik radgrid marks a row as "modified"

- by Scott Vercuski

I am working with the Telerik Winforms Radgrid version 2009.2.9.701 in visual studio 2008 (C#) and I've come across and issue I can't seem to find a solution for. When the radgrid is populated and the user changes a cell within a row, the row is not flagged as "modified" until the user actually clicks onto another location on the datagrid. If the user modifies any values in a row and immediately clicks the "Save" button on my winform, the row is not flagged as having been modified and is not showing up in my list of modified rows. I am using the following code to gather the modified rows ... DataTable modifiedRows = dataTable.GetChanges(DataRowState.Modified); My question is as follows: Is there a way to mark a row as "Modified" when the user changes a value in ANY cell in the row, without the user having to click off of the row before clicking the save button. I can't seem to find the flag that marks a data row as "Modified". Thank you for your help, it is much appreciated.

Cloud Based Load Testing Using TF Service & VS 2013

- by Tarun Arora [Microsoft MVP]

Originally posted on: http://geekswithblogs.net/TarunArora/archive/2013/06/30/cloud-based-load-testing-using-tf-service-amp-vs-2013.aspx One of the new features announced as part of the Visual Studio 2013 Ultimate Preview is ‘Cloud Based Load Testing’. In this blog post I’ll walk you through, What is Cloud Based Load Testing? How have I been using this feature? – Success story! Where can you find more resources on this feature? What is Cloud Based Load Testing? It goes without saying that performance testing your application not only gives you the confidence that the application will work under heavy levels of stress but also gives you the ability to test how scalable the architecture of your application is. It is important to know how much is too much for your application! Working with various clients in the industry I have realized that the biggest barriers in Load Testing & Performance Testing adoption are, High infrastructure and administration cost that comes with this phase of testing Time taken to procure & set up the test infrastructure Finding use for this infrastructure investment after completion of testing Is cloud the answer? 100% Visual Studio Compatible Scalable and Realistic Start testing in < 2 minutes Intuitive Pay only for what you need Use existing on premise tests on cloud There are a lot of vendors out there offering Cloud Based Load Testing, to name a few, Load Storm Soasta Blaze Meter Blitz And others… The question you may want to ask is, why should you go with Microsoft’s Cloud based Load Test offering. If you are a Microsoft shop or already have investments in Microsoft technologies, you’ll see great benefit in the natural integration this offers with existing Microsoft products such as Visual Studio and Windows Azure. For example, your existing Web tests authored in Visual Studio 2010 or Visual Studio 2012 will run on the cloud without requiring any modifications what so ever. Microsoft’s cloud test rig also supports API based testing, for example, if you are building a WPF application which consumes WCF services, you can write unit tests to invoke the WCF service, these tests can be run on the cloud test rig and loaded with ‘N’ concurrent users for performance testing. If you have your assets already hosted in the Azure and possibly in the same data centre as the Cloud test rig, your Azure app will not incur a usage cost because of the generated traffic since the traffic is coming from the same data centre. The licensing or pricing information on Microsoft’s cloud based Load test service is yet to be announced, but I would expect this to be priced attractively to match the market competition. The only additional configuration required for running load tests on Microsoft Cloud based Load Tests service is to select the Test run location as Run tests using Visual Studio Team Foundation Service, How have I been using Microsoft’s Cloud based Load Test Service? I have been part of the Microsoft Cloud Based Load Test Service advisory council for the last 7 months. This gave the opportunity to see the product shape up from concept to working solution. I was also the first person outside of Microsoft to try this offering out. This gave me the opportunity to test real world application at various clients using the Microsoft Load Test Service and provide real world feedback to the Microsoft product team. One of the most recent systems I tested using the Load Test Service has been an insurance quote generation engine. This insurance quote generation engine is, hosted in Windows Azure expected to get quote requests from across the globe expected to handle 5 Million quote requests in a day (not clear how this load will be distributed across the day) There was no way, I could simulate such kind of load from on premise without standing up additional hardware. But Microsoft’s Cloud based Load Test service allowed me to test my key performance testing scenarios, i.e. Simulate expected Load, Endurance Testing, Threshold Testing and Testing for Latency. Simulating expected load: approach to devising a load pattern My approach to devising a load test pattern has been to run the test scenario with 1 user to figure out the response time. Then work out how many users are required to reach the target load. So, for example, to invoke 1 quote from the quote engine software takes 0.5 seconds. Now if you do the math, 1 quote request by 1 user = 0.5 seconds quotes generated by 1 user in 24 hour = 1 * (((2 * 60) * 60) * 24) = 172,800 quotes generated by 30 users in 24 hours = 172,800 * 30 = 5,184,000 This was a very simple example, if your application requires more concurrent users to test scenario’s such as caching, etc then you can devise your own load pattern, some examples of load test patterns can be found here. Endurance Testing To test for endurance, I loaded the quote generation engine with an expected fixed user load and ran the test for very long duration such as over 48 hours and observed the affect of the long running test on the Azure infrastructure. Currently Microsoft Load Test service does not support metrics from the machine under test. I used Azure diagnostics to begin with, but later started using Cerebrata Azure Diagnostics Manager to capture the metrics of the machine under test. Threshold Testing To figure out how much user load the application could cope with before falling on its belly, I opted to step load the quote generation engine by incrementing user load with different variations of incremental user load per minute till the application crashed out and forced an IIS reset. Testing for Latency Currently the Microsoft Load Test service does not support generating geographically distributed load, I however, deployed the insurance quote generation engine in different Azure data centres and ran the same set of performance tests to measure for latency. Because I could compare load test results from different runs by exporting the results to excel (this feature is provided out of the box right from Visual Studio 2010) I could see the different in response times. More resources on Microsoft Cloud based Load Test Service A few important links to get you started, Download Visual Studio Ultimate 2013 Preview Getting started guide for load testing using Team Foundation Service Troubleshooting guide for FAQs and known issues Team Foundation Service forum for questions and support Detailed demo and presentation (link to Tech-Ed session recording) Detailed demo and presentation (link to Build session recording) There a few limits on the usage of Microsoft Cloud based Load Test service that you can read about here. If you have any feedback on Microsoft Cloud based Load Test service, feel free to share it with the product team via the Visual Studio User Voice forum. I hope you found this useful.

Google App Engine - Figure out the time the current request reached the app engine

- by Spines

Is there a way I can figure out the time the current request reached the app engine? For example a user might make a request to my app, but due to app engine latencies my code might not start handling the request until one second later, is there a way I can figure out that the user has already had to wait one second? The reason I want to know how to do this is because I want to do different things based on if the user already had to wait. If the user already had to wait a significant amount of time I will just serve them a page out of the cache, if the user hasn't had to wait yet then I will serve them a page which takes a while to render.

WCF Security Transport Security Questions

- by shyneman

I'm writing a set of WCF services that rely on transport security with Windows Authentication using the trusted subsystem model. However, I want to perform authorization based on the original client user that initiated the request (e.g. a user from a website with a username/password). I'm planning to achieve this by adding the original user's credentials in the header before the client sends the message and then the service will use the supplied credentials to authorize the user. So I have a few questions about this implementation: 1) using transport security with windows auth, I do NOT need to worry about again encrypting the passed credentials to ensure the validity... WCF automatically takes care of this - is this correct? 2) how does this implementation prevent a malicious service, running under some windows account within the domain, to send a message tagged with spoofed credentials. for e.g. a malicious service replaces the credentials with an Admin user to do something bad? Thanks for any help.

Code assist in (jsp /jstl) view for Spring MVC model objects in Eclipse

- by Bjorn Thor Jonsson

In Spring MVC when placing an object in the view model like so: public String getUser( Model model ) { //...fetch user... model.addAttribute( "user", user ); return "viewName"; } and accessing it's values in the JSP / JSTL view like this: ... <p> ${user.name} </p> ... I'm wondering if it is possible to have code assist for the user object in the view? The IDE I'm using is MyEclipse but it would be interesting to know if this is possible in other editors as well. Thanks.
