• Exit Infragistics, Enter Telerik

  - by Anthony Trudeau

  Today I made the purchase of the Premium Collection of components from Telerik.  This follows an evaluation I’ve been doing to replace the Infragistics components we currently use for Windows Forms, ASP.NET MVC, and WPF. It was not a formal evaluation.  I had already decided to move the company away from Infragistics.  That decision was mostly born out of frustration with support over using the Infragistics components in my first production MVC application. One such issue was a simple scenario where you have a model that has a scalar property that can be one value out of a list.  The built-in combobox does this, but I was told by Infragistics support that they didn’t support it – and it took them several emails and days of waiting between responses to determine that.  I implemented this in Telerik in a minute not including the several minutes it took me to get a rudimentary understanding for the component and its API. Here’s the code using the built-in combobox:@Html.DropDownListFor(x => x.VendorId, new SelectList(ViewBag.Vendors, "VendorId", "VendorName", Model.VendorId), "Select Id") Here’s the code using the Telerik combobox:@(Html.Telerik().ComboBoxFor(model => model.VendorId) .AutoFill(true) .BindTo(new SelectList(ViewBag.Vendors, "VendorId", "VendorName", Model.VendorId)) )   I chose Telerik over other competitors based on the professional appearance of their website, and how easy it was to find information.  I’d like to say I had time to evaluate other Infragistics competitors.  Due to time constraints I had to make an initial decision based on superficial, but still important things. I picked Telerik with the plan to only look further at other companies if my evaluation didn’t meet my expectations.  Luckily they did, because I didn’t relish the thought of carving out more time to evaluate another set of components. Overall my experience with Telerik has been superior to Infragistics in every way.  The installation was easy using their control panel installer application.  Getting up to speed has been easy.  And the communication from Telerik has met my expectations.  And we’ll continue to be good as long as I don’t start getting email messages from a sales rep saying that they want to talk to me about training and consulting – I’m looking at you Infragistics.

• Custom Session Management using HashTable

  - by kaleidoscope

  ASP.NET session state lets you associate a server-side string or object dictionary containing state data with a particular HTTP client session. A session is defined as a series of requests issued by the same client within a certain period of time, and is managed by associating a session ID with each unique client. The ID is supplied by the client on each request, either in a cookie or as a special fragment of the request URL. The session data is stored on the server side in one of the supported session state stores, which include in-process memory, SQL Server™ database, and the ASP.NET State Server service. The latter two modes enable session state to be shared among multiple Web servers on a Web farm and do not require server affinity. Implement Custom session Handler you need to follow following process : 1. Create class library which will inherit from  SessionStateStoreProviderBase abstract Class. 2. Implement all abstract Method in your base class. 3.Change Mode of session to “Custom” in web.config file and provide Provider as your Namespace with classname. <sessionState mode=”Custom” customProvider=”Namespace.classname”> <Providers> <add name=”Name” type=”Namespace.classname”> </sessionstate> For more Details Please refer following links :   http://msdn.microsoft.com/en-us/magazine/cc163730.aspx http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstatestoreproviderbase.aspx - Chandraprakash, S Technorati Tags: Chandraprakash,Session state Managment

• Visual Studio 2010 Keyboard Shortcut Posters Available

  - by Jim Duffy

  I’m a firm believer in the productivity gains you experience when using keyboard shortcuts in Visual Studio. If you’re not using keyboard shortcuts while coding then your productivity is suffering. Some of my favorites (omitting the obvious ones like F5 to start debugging) as are: Ctrl+K, C – Comment section of code Ctrl+K, U – Uncomment section of code Ctrl+K, D – Format the current document (indentation, etc.) Shift+Alt+C – Add new class to a project Shift+Alt+A – Add existing item to a project Ctrl+Shift+A – Add new item to a project The good news is all of these and a TON of others are all documented in the Visual Studio Keyboard Shortcut Posters (available as PDFs). The only problem is there are so many you need a printer capable of printing on larger paper because while you can read them all on 8 1/2 x 11 paper in landscape mode, for them to be a valuable quick reference on your cubicle wall you’re going to need to print them on large paper. If you don’t have a printer capable of producing large sized printouts head down to Office Depot, Staples, FedEx Office, or your favorite print shop and have them print one for you. Oh and one last thing, I’d really like Microsoft to take those people’s picture off them. Really? Do we need to look at these people when trying to improve our productivity? Have a day. :-|

• Thoughts about MVC

  - by ayyash

  so i figured this one out, as a newcomer to the web development scene from the telecom biz, where we dealt with low level hardware API's, and a C++ fanboy, i tend to be bothered by automagical code, yes i appreciate the effort that went into it, and i certainly appreciate the luxury it provides to get more things done, but i just don't get it. so i decided to change that, and start investigating the new MVC based web apps, and at first it was like hitting a brick wall, i knew MVC from MFC days, so i'm familiar with the pattern, but i just couldn't get my head around the web version of it, till i came to realize the routing, is actually a separate feature to be inspected, much like understanding how LINQ works by better understanding anonymous objects. and so this article serve as an introduction to the following blogs where i share my views of how asp.net routing works, and then leverage that to the MVC level, and play around that field for a bit. as with most of my shared knowladge that may seem trivial to some, but i guess a newcomer's point of view can be useful for some folks out there.

• ASP.NET Membership Password Hash -- .NET 3.5 to .NET 4 Upgrade Surprise!

  - by David Hoerster

  I'm in the process of evaluating how my team will upgrade our product from .NET 3.5 SP1 to .NET 4. I expected the upgrade to be pretty smooth with very few, if any, upgrade issues. To my delight, the upgrade wizard said that everything upgraded without a problem. I thought I was home free, until I decided to build and run the application. A big problem was staring me in the face -- I couldn't log on. Our product is using a custom ASP.NET Membership Provider, but essentially it's a modified SqlMembershipProvider with some additional properties. And my login was failing during the OnAuthenticate event handler of my ASP.NET Login control, right where it was calling my provider's ValidateUser method. After a little digging, it turns out that the password hash that the membership provider was using to compare against the stored password hash in the membership database tables was different. I compared the password hash from the .NET 4 code line, and it was a different generated hash than my .NET 3.5 code line. (Tip -- when upgrading, always keep a valid debug copy of your app handy in case you have to step through a lot of code.) So it was a strange situation, but at least I knew what the problem was. Now the question was, "Why was it happening?" Turns out that a breaking change in .NET 4 is that the default hash algorithm changed to SHA256. Hey, that's great -- stronger hashing algorithm. But what do I do with all the hashed passwords in my database that were created using SHA1? Well, you can make two quick changes to your app's web.config and everything will be OK. Basically, you need to override the default HashAlgorithmTypeproperty of your membership provider. Here are the two places to do that: 1. At the beginning of your element, add the following element: <system.web> <machineKey validation="SHA1" /> ... </system.web> 2. On your element under , add the following hashAlgorithmType attribute: <system.web> <membership defaultProvider="myMembership" hashAlgorithmType="SHA1"> ... </system.web> After that, you should be good to go! Hope this helps.

• Adventures in MVVM &ndash; My ViewModel Base &ndash; Silverlight Support!

  - by Brian Genisio's House Of Bilz

  More Adventures in MVVM In my last post, I outlined the powerful features that are available in the ViewModelSupport.  It takes advantage of the dynamic features of C# 4.0 (as well as some 3.0 goodies) to help eliminate the plumbing that often comes with writing ViewModels.  If you are interested in learning about the capabilities, please take a look at that post and look at the code on CodePlex.  When I wrote about the ViewModel base class, I complained that the features did not work in Silverlight because as of 4.0, it does not support binding to dynamic properties.  Although I still think this is a bummer, I am happy to say that I have come up with a workaround.  In the Silverlight version of my base class, I include a PropertyCollectionConverter that lets you bind to dynamic properties in the ViewModelBase, especially the convention-based commands that the base class supports. To take advantage of any properties that are not statically defined, you can bind to the Properties property of the ViewModel and pass in a converter parameter for the name of the property you want to bind. For example, a ViewModel that looks like this: public class ExampleViewModel : ViewModelBase { public void Execute_MyCommand() { Set("Text", "Foo"); } } Can bind to the dynamic property and the convention-based command with the following XAML. <TextBlock Text="{Binding Properties, Converter={StaticResource PropertiesConverter}, ConverterParameter=Text}" Margin="5" /> <Button Content="Execute MyCommand" Command="{Binding Properties, Converter={StaticResource PropertiesConverter}, ConverterParameter=MyCommand}" Margin="5" /> Of course, it is not as pretty as binding to Text and MyCommand like you can in WPF.  But, it is better than having a failed feature.  This allows you to share your ViewModels between WPF and Silverlight very easily.  <BeatDeadHorse>Hopefully, in Silverlight 5.0, we will see binding to dynamic properties more directly????</BeatDeadHorse>

• jQuery "Auto Post-back" Select/Drop-Down List

  - by Doug Lampe

  I have one common piece of jQuery code which I use to submit a form any time the selection changes on a drop-down list (HTML select tag).  This is similar to setting AutoPostBack = true in ASP.Net.  I use a single CSS class (autoSubmit) to annotate that I want the drop-down to force the form to submit on change so the HTML looks something like this: <select id="myAutoSubmitDropDown" name="myAutoSubmitDropDown" class="autoSubmit">     <option value="1">Option 1</option>     <option value="2">Option 2</option> </select> Then the following jQuery will look for any element with this CSS class and submit the parent form when the value is changed: function wireUpAutoSubmit() {   $(".autoSubmit").each(function (index) {     $(this).change(function () {       $(this).closest('form').submit();     })   }); } I put this in a separate function since I might need to wire this up explicitly after an ajax call.  Therefore I use the following code to set this method to fire when the DOM is loaded: $(document).ready(function () {   wireUpAutoSubmit(); });

• Making the most of next weeks SharePoint 2010 developer training

  - by Eric Nelson

  [you can still register if you are free on the afternoons of 9th to 11th – UK time] We have 50+ registrations with more coming in – which is fantastic. Please read on to make the most of the training. Background We have structured the training to make sure that you can still learn lots during the three days even if you do not have SharePoint 2010 installed. Additionally the course is based around a subset of the channel 9 training to allow you to easily dig deeper or look again at specific areas. Which means if you have zero time between now and next Wednesday then you are still good to go. But if you can do some pre-work you will likely get even more out of the three days. Step 1: Check out the topics and resources available on-demand The course is based around a subset of the channel 9 training to allow you to easily dig deeper or look again at specific areas. Take a lap around the SharePoint 2010 Training Course on Channel 9 Download the SharePoint Developer Training Kit Step 2: Use a pre-configured Virtual Machine which you can download (best start today – it is large!) Consider using the VM we created If you don't have access to SharePoint 2010. You will need a 64bit host OS and bare minimum of 4GB of RAM. 8GB recommended. Virtual PC can not be used with this VM – Virtual PC only supports 32bit guests. The 2010-7a Information Worker VM gives you everything you need to develop for SharePoint 2010. Watch the Video on how to use this VM Download the VM Remember you only need to download the “parts” for the 2010-7a VM. There are 3 subtly different ways of using this VM: Easiest is to follow the advice of the video and get yourself a host OS of Windows Server 2008 R2 with Hyper-V and simply use the VM Alternatively you can take the VHD and create a “Boot to VHD” if you have Windows 7 Ultimate or Enterprise Edition. This works really well – especially if you are already familiar with “Boot to VHD” (This post I did will help you get started) Or you can take the VHD and use an alternative VM tool such as VirtualBox if you have a different host OS. NB: This tends to involve some work to get everything running fine. Check out parts 1 to 3 from Rolly and if you go with Virtual Box use an IDE controller not SATA. SATA will blue screen. Note in the screenshot below I also converted the vhd to a vmdk. I used the FREE Starwind Converter to do this whilst I was fighting blue screens – not sure its necessary as VirtualBox does now work with VHDs. or Step 3 – Install SharePoint 2010 on a 64bit Windows 7 or Vista Host I haven’t tried this but it is now supported. Check out MSDN. Final notes: I am in the process of securing a number of hosted VMs for ISVs directly managed by my team. Your Architect Evangelist will have details once I have them! Else we can sort out on the Wed. Regrettably I am unable to give folks 1:1 support on any issues around Boot to VHD, 3rd party VM products etc. Related Links: Check you are fully plugged into the work of my team – have you done these simple steps including joining our new LinkedIn group?

• Find an element in a JavaScript array

• SBUG --> UK Connected Systems User Group

  - by Michael Stephenson

  Following a recent user group meeting we have decided that the UK SOA/BPM User Group will be renamed to the UK Connected Systems User Group.  The reasons for this are as follows: 1. Other user groups who cover the same topics as us are all called something similar 2. We feel the name change will help to increase user group membership The focus and topics of the user group will remain the same.

• PublishingWeb.ExcludeFromNavigation Missing

  - by Michael Van Cleave

  So recently I have had to make the transition from the SharePoint 2007 codebase to SharePoint 2010 codebase. Needless to say there hasn't been much difficulty in the changeover. However in a set of code that I was playing around with and transitioning I did find one change that might cause some pain to others out there that have been programming against the PublishingWeb object in the Microsoft.SharePoint.Publishing namespace. The 2007 snippet of code that work just fine in 2007 looks like: using (SPSite site = new SPSite(url)) using (SPWeb web = site.OpenWeb()) {      PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(web);     publishingWeb.ExcludeFromNavigation(true, itemID);     publishingWeb.Update(); } The 2010 update to the code looks like: using (SPSite site = new SPSite(url)) using (SPWeb web = site.OpenWeb()) {     PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(web);     publishingWeb.Navigation.ExcludeFromNavigation(true, itemID); //--Had to reference the Navigation object.     publishingWeb.Update(); } The purpose of the code is to keep a page from showing up on the global or current navigation when it is added to the pages library. However you see that the update to the 2010 codebase actually makes more "object" sense. It specifies that you are technically affecting the Navigation of the Publishing Web, instead of the Publishing Web itself. I know that this isn't a difficult problem to fix, but I thought it would be something quick to help out the general public. Michael

• Creating a Document Library with Content Type in code

  - by David Jacobus

  Originally posted on: http://geekswithblogs.net/djacobus/archive/2013/10/15/154360.aspxIn the past, I have shown how to create a list content type and add the content type to a list in code.  As a Developer, many of the artifacts which we create are widgets which have a List or Document Library as the back end.   We need to be able to create our applications (Web Part, etc.) without having the user involved except to enter the list item data.  Today, I will show you how to do the same with a document library.    A summary of what we will do is as follows:   1.   Create an Empty SharePoint Project in Visual Studio 2.   Add a Code Folder in the solution and Drag and Drop Utilities and Extensions Libraries to the solution 3.   Create a new Feature and add and event receiver  all the code will be in the event receiver 4.   Add the fields which will extend the built-in Document content type 5.   If the Content Type does not exist, Create it 6.   If the Document Library does not exist, Create it with the new Content Type inherited from the Document Content Type 7.   Delete the Document Content Type from the Library (as we have a new one which inherited from it) 8.   Add the fields which we want to be visible from the fields added to the new Content Type   Here we go:   Create an Empty SharePoint Project in Visual Studio      Add a Code Folder in the solution and Drag and Drop Utilities and Extensions Libraries to the solution       The Utilities and Extensions Library will be part of this project which I will provide a download link at the end of this post.  Drag and drop them into your project.  If Dragged and Dropped from windows explorer you will need to show all files and then include them in your project.  Change the Namespace to agree with your project.   Create a new Feature and add and event receiver  all the code will be in the event receiver.  Here We added a new Feature called “CreateDocLib”  and then right click to add an Event Receiver All of our code will be in this Event Receiver.  For this Demo I will only be using the Feature Activated Event.      From this point on we will be looking at code!    We are adding two constants for use columGroup (How we want SharePoint to Group them, usually Company Name) and ctName(ContentType Name)  using System; using System.Runtime.InteropServices; using System.Security.Permissions; using Microsoft.SharePoint; namespace CreateDocLib.Features.CreateDocLib { /// <summary> /// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade. /// </summary> /// <remarks> /// The GUID attached to this class may be used during packaging and should not be modified. /// </remarks> [Guid("56e6897c-97c4-41ac-bc5b-5cd2c04f2dd1")] public class CreateDocLibEventReceiver : SPFeatureReceiver { const string columnGroup = "DJ"; const string ctName = "DJDocLib"; } }     Here we are creating the Feature Activated event.   Adding the new fields (Site Columns) ,  Testing if the Content Type Exists, if not adding it.  Testing if the document Library exists, if not adding it.   #region DocLib public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb spWeb = properties.GetWeb() as SPWeb) { //add the fields addFields(spWeb); //add content type SPContentType testCT = spWeb.ContentTypes[ctName]; // we will not create the content type if it exists if (testCT == null) { //the content type does not exist add it addContentType(spWeb, ctName); } if ((spWeb.Lists.TryGetList("MyDocuments") == null)) { //create the list if it dosen't to exist CreateDocLib(spWeb); } } } #endregion The addFields method uses the utilities library to add site columns to the site. We can add as many fields within this method as we like. Here we are adding one for demonstration purposes. Icon as a Url type.  public void addFields(SPWeb spWeb) { Utilities.addField(spWeb, "Icon", SPFieldType.URL, false, columnGroup); }The addContentType method add the new Content Type to the site Content Types. We have already checked to see that it does not exist. In addition, here is where we add the linkages from our site columns previously created to our new Content Type   private static void addContentType(SPWeb spWeb, string name) { SPContentType myContentType = new SPContentType(spWeb.ContentTypes["Document"], spWeb.ContentTypes, name) { Group = columnGroup }; spWeb.ContentTypes.Add(myContentType); addContentTypeLinkages(spWeb, myContentType); myContentType.Update(); } Here we are adding just one linkage as we only have one additional field in our Content Type public static void addContentTypeLinkages(SPWeb spWeb, SPContentType ct) { Utilities.addContentTypeLink(spWeb, "Icon", ct); } Next we add the logic to create our new Document Library, which we have already checked to see if it exists.  We create the document library and turn on content types.  Add the new content type and then delete the old “Document” content types.   private void CreateDocLib(SPWeb web) { using (var site = new SPSite(web.Url)) { var web1 = site.RootWeb; var listId = web1.Lists.Add("MyDocuments", string.Empty, SPListTemplateType.DocumentLibrary); var lib = web1.Lists[listId] as SPDocumentLibrary; lib.ContentTypesEnabled = true; var docType = web.ContentTypes[ctName]; lib.ContentTypes.Add(docType); lib.ContentTypes.Delete(lib.ContentTypes["Document"].Id); lib.Update(); AddLibrarySettings(web1, lib); } }  Finally, we set some document library settings on our new document library with the AddLibrarySettings method. We then ensure that the new site column is visible when viewed in the browser.  private void AddLibrarySettings(SPWeb web, SPDocumentLibrary lib) { lib.OnQuickLaunch = true; lib.ForceCheckout = true; lib.EnableVersioning = true; lib.MajorVersionLimit = 5; lib.EnableMinorVersions = true; lib.MajorWithMinorVersionsLimit = 5; lib.Update(); var view = lib.DefaultView; view.ViewFields.Add("Icon"); view.Update(); } Okay, what's cool here: In a few lines of code, we have created site columns, A content Type, a document library. As a developer, I use this functionality all the time. For instance, I could now just add a web part to this same solutionwhich uses this document Library. I love SharePoint! Here is the complete solution: Create Document Library Code

• Marshalling the value of a char* ANSI string DLL API parameter into a C# string

  - by Brian Biales

  For those who do not mix .NET C# code with legacy DLL's that use char* pointers on a regular basis, the process to convert the strings one way or the other is non-obvious. This is not a comprehensive article on the topic at all, but rather an example of something that took me some time to go find, maybe it will save someone else the time. I am utilizing a third party too that uses a call back function to inform my application of its progress.  This callback includes a pointer that under some circumstances is a pointer to an ANSI character string.  I just need to marshal it into a C# string variable.  Seems pretty simple, yes?  Well, it is, (as are most things, once you know how to do them). The parameter of my callback function is of type IntPtr, which implies it is an integer representation of a pointer.  If I know the pointer is pointing to a simple ANSI string, here is a simple static method to copy it to a C# string: private static string GetStringFromCharStar(IntPtr ptr) {     return System.Runtime.InteropServices.Marshal.PtrToStringAnsi(ptr); } The System.Runtime.InteropServices is where to look any time you are mixing legacy unmanaged code with your .NET application.

• Combining Shared Secret and Username Token – Azure Service Bus

  - by Michael Stephenson

  As discussed in the introduction article this walkthrough will explain how you can implement WCF security with the Windows Azure Service Bus to ensure that you can protect your endpoint in the cloud with a shared secret but also flow through a username token so that in your listening WCF service you will be able to identify who sent the message. This could either be in the form of an application or a user depending on how you want to use your token. Prerequisites Before going into the walk through I want to explain a few assumptions about the scenario we are implementing but to keep the article shorter I am not going to walk through all of the steps in how to setup some of this. In the solution we have a simple console application which will represent the client application. There is also the services WCF application which contains the WCF service we will expose via the Windows Azure Service Bus. The WCF Service application in this example was hosted in IIS 7 on Windows 2008 R2 with AppFabric Server installed and configured to auto-start the WCF listening services. I am not going to go through significant detail around the IIS setup because it should not matter in relation to this article however if you want to understand more about how to configure WCF and IIS for such a scenario please refer to the following paper which goes into a lot of detail about how to configure this. The link is: http://tinyurl.com/8s5nwrz   The Service Component To begin with let's look at the service component and how it can be configured to listen to the service bus using a shared secret but to also accept a username token from the client. In the sample the service component is called Acme.Azure.ServiceBus.Poc.UN.Services. It has a single service which is the Visual Studio template for a WCF service when you add a new WCF Service Application so we have a service called Service1 with its Echo method. Nothing special so far!.... The next step is to look at the web.config file to see how we have configured the WCF service. In the services section of the WCF configuration you can see I have created my service and I have created a local endpoint which I simply used to do a little bit of diagnostics and to check it was working, but more importantly there is the Windows Azure endpoint which is using the ws2007HttpRelayBinding (note that this should also work just the same if your using netTcpRelayBinding). The key points to note on the above picture are the service behavior called MyServiceBehaviour and the service bus endpoints behavior called MyEndpointBehaviour. We will go into these in more detail later.   The Relay Binding The relay binding for the service has been configured to use the TransportWithMessageCredential security mode. This is the important bit where the transport security really relates to the interaction between the service and listening to the Azure Service Bus and the message credential is where we will use our username token like we have specified in the message/clientCrentialType attribute. Note also that we have left the relayClientAuthenticationType set to RelayAccessToken. This means that authentication will be made against ACS for accessing the service bus and messages will not be accepted from any sender who has not been authenticated by ACS.   The Endpoint Behaviour In the below picture you can see the endpoint behavior which is configured to use the shared secret client credential for accessing the service bus and also for diagnostic purposes I have included the service registry element. Hopefully if you are familiar with using Windows Azure Service Bus relay feature the above is very familiar to you and this is a very common setup for this section. There is nothing specific to the username token implementation here. The Service Behaviour Now we come to the bit with most of the username token bits in it. When you configure the service behavior I have included the serviceCredentials element and then setup to use userNameAuthentication and you can see that I have created my own custom username token validator.   This setup means that WCF will hand off to my class for validating the username token details. I have also added the serviceSecurityAudit element to give me a simple auditing of access capability. My UsernamePassword Validator The below picture shows you the details of the username password validator class I have implemented. WCF will hand off to this class when validating the token and give me a nice way to check the token credentials against an on-premise store. You have all of the validation features with a non-service bus WCF implementation available such as validating the username password against active directory or ASP.net membership features or as in my case above something much simpler.   The Client Now let's take a look at the client side of this solution and how we can configure the client to authenticate against ACS but also send a username token over to the service component so it can implement additional security checks on-premise. I have a console application and in the program class I want to use the proxy generated with Add Service Reference to send a message via the Azure Service Bus. You can see in my WCF client configuration below I have setup my details for the azure service bus url and am using the ws2007HttpRelayBinding. Next is my configuration for the relay binding. You can see below I have configured security to use TransportWithMessageCredential so we will flow the username token with the message and also the RelayAccessToken relayClientAuthenticationType which means the component will validate against ACS before being allowed to access the relay endpoint to send a message.     After the binding we need to configure the endpoint behavior like in the below picture. This is the normal configuration to use a shared secret for accessing a Service Bus endpoint.   Finally below we have the code of the client in the console application which will call the service bus. You can see that we have created our proxy and then made a normal call to a WCF service but this time we have also set the ClientCredentials to use the appropriate username and password which will be flown through the service bus and to our service which will validate them.     Conclusion As you can see from the above walkthrough it is not too difficult to configure a service to use both a shared secret and username token at the same time. This gives you the power and protection offered by the access control service in the cloud but also the ability to flow additional tokens to the on-premise component for additional security features to be implemented.

• BizTalk: Internals: the Partner Direct Ports and the Orchestration Chains

  - by Leonid Ganeline

  Partner Direct Port is one of the BizTalk hidden gems. It opens simple ways to the several messaging patterns. This article based on the Kevin Lam’s blog article. The article is pretty detailed but it still leaves several unclear pieces. So I have created a sample and will show how it works from different perspectives. Requirements We should create an orchestration chain where the messages should be routed from the first stage to the second stage. The messages should not be modified. All messages has the same message type. Common artifacts Source code can be downloaded here. It is interesting but all orchestrations use only one port type. It is possible because all ports are one-way ports and use only one operation. I have added a B orchestration. It helps to test the sample, showing all test messages in channel. The Receive shape Filter is empty. A Receive Port (R_Shema1Direct) is a plain Direct Port. As you can see, a subscription expression of this direct port has only one part, the MessageType for our test schema: A Filer is empty but, as you know, a link from the Receive shape to the Port creates this MessageType expression. I use only one Physical Receive File port to send a message to all processes. Each orchestration outputs a Trace.WriteLine(“<Orchestration Name>”). Forward Binding This sample has three orchestrations: A_1, A_21 and A_22. A_1 is a sender, A_21 and A_22 are receivers. Here is a subscription of the A_1 orchestration: It has two parts A MessageType. The same was for the B orchestration. A ReceivePortID. There was no such parameter for the B orchestration. It was created because I have bound the orchestration port with Physical Receive File port. This binding means the PortID parameter is added to the subscription. How to set up the ports? All ports involved in the message exchange should be the same port type. It forces us to use the same operation and the same message type for the bound ports. This step as absolutely contra-intuitive. We have to choose a Partner Orchestration parameter for the sending orchestration, A_1. The first strange thing is it is not a partner orchestration we have to choose but an orchestration port. But the most strange thing is we have to choose exactly this orchestration and exactly this port.It is not a port from the partner, receive orchestrations, A_21 or A_22, but it is A_1 orchestration and S_SentFromA_1 port. Now we have to choose a Partner Orchestration parameter for the received orchestrations, A_21 and A_22. Nothing strange is here except a parameter name. We choose the port of the sender, A_1 orchestration and S_SentFromA_1 port. As you can see the Partner Orchestration parameter for the sender and receiver orchestrations is the same. Testing I dropped a test file in a file folder. There we go: A dropped file was received by B and by A_1 A_1 sent a message forward. A message was received by B, A_21, A_22 Let’s look at a context of a message sent by A_1 on the second step: A MessageType part. It is quite expected. A PartnerService, a ParnerPort, an Operation. All those parameters were set up in the Partner Orchestration parameter on both bound ports.     Now let’s see a subscription of the A_21 and A_22 orchestrations. Now it makes sense. That’s why we have chosen such a strange value for the Partner Orchestration parameter of the sending orchestration. Inverse Binding This sample has three orchestrations: A_11, A_12 and A_2. A_11 and A_12 are senders, A_2 is receiver. How to set up the ports? All ports involved in the message exchange should be the same port type. It forces us to use the same operation and the same message type for the bound ports. This step as absolutely contra-intuitive. We have to choose a Partner Orchestration parameter for a receiving orchestration, A_2. The first strange thing is it is not a partner orchestration we have to choose but an orchestration port. But the most strange thing is we have to choose exactly this orchestration and exactly this port.It is not a port from the partner, sent orchestrations, A_11 or A_12, but it is A_2 orchestration and R_SentToA_2 port. Now we have to choose a Partner Orchestration parameter for the sending orchestrations, A_11 and A_12. Nothing strange is here except a parameter name. We choose the port of the sender, A_2 orchestration and R_SentToA_2 port. Testing I dropped a test file in a file folder. There we go: A dropped file was received by B, A_11 and by A_12 A_11 and A_12 sent two messages forward. The messages were received by B, A_2 Let’s see what was a context of a message sent by A_1 on the second step: A MessageType part. It is quite expected. A PartnerService, a ParnerPort, an Operation. All those parameters were set up in the Partner Orchestration parameter on both bound ports. Here is a subscription of the A_2 orchestration. Models I had a hard time trying to explain the Partner Direct Ports in simple terms. I have finished with this model: Forward Binding Receivers know a Sender. Sender doesn’t know Receivers. Publishers know a Subscriber. Subscriber doesn’t know Publishers. 1 –> 1 1 –> M Inverse Binding Senders know a Receiver. Receiver doesn’t know Senders. Subscribers know a Publisher. Publisher doesn’t know Subscribers. 1 –> 1 M –> 1 Notes   Orchestration chain It’s worth to note, the Partner Direct Port Binding creates a chain opened from one side and closed from another. The Forward Binding: A new Receiver can be added at run-time. The Sender can not be changed without design-time changes in Receivers. The Inverse Binding: A new Sender can be added at run-time. The Receiver can not be changed without design-time changes in Senders.

• Taking a screenshot from within a Silverlight #WP7 application

  - by Laurent Bugnion

  Often times, you want to take a screenshot of an application’s page. There can be multiple reasons. For instance, you can use this to provide an easy feedback method to beta testers. I find this super invaluable when working on integration of design in an app, and the user can take quick screenshots, attach them to an email and send them to me directly from the Windows Phone device. However, the same mechanism can also be used to provide screenshots are a feature of the app, for example if the user wants to save the current status of his application, etc. Caveats Note the following: The code requires an XNA library to save the picture to the media library. To have this, follow the steps: In your application (or class library), add a reference to Microsoft.Xna.Framework. In your code, add a “using” statement to Microsoft.Xna.Framework.Media. In the Properties folder, open WMAppManifest.xml and add the following capability: ID_CAP_MEDIALIB. The method call will fail with an exception if the device is connected to the Zune application on the PC. To avoid this, either disconnect the device when testing, or end the Zune application on the PC. While the method call will not fail on the emulator, there is no way to access the media library, so it is pretty much useless on this platform. This method only prints Silverlight elements to the output image. Other elements (such as a WebBrowser control’s content for instance) will output a black rectangle. The code public static void SaveToMediaLibrary( FrameworkElement element, string title) { try { var bmp = new WriteableBitmap(element, null); var ms = new MemoryStream(); bmp.SaveJpeg( ms, (int)element.ActualWidth, (int)element.ActualHeight, 0, 100); ms.Seek(0, SeekOrigin.Begin); var lib = new MediaLibrary(); var filePath = string.Format(title + ".jpg"); lib.SavePicture(filePath, ms); MessageBox.Show( "Saved in your media library!", "Done", MessageBoxButton.OK); } catch { MessageBox.Show( "There was an error. Please disconnect your phone from the computer before saving.", "Cannot save", MessageBoxButton.OK); } } This method can save any FrameworkElement. Typically I use it to save a whole page, but you can pass any other element to it. On line 7, we create a new WriteableBitmap. This excellent class can render a visual tree into a bitmap. Note that for even more features, you can use the great WriteableBitmapEx class library (which is open source). On lines 9 to 16, we save the WriteableBitmap to a MemoryStream. The only format supported by default is JPEG, however it is possible to convert to other formats with the ImageTools library (also open source). Lines 18 to 20 save the picture to the Windows Phone device’s media library. Using the image To retrieve the image, simply launch the Pictures library on the phone. The image will be in Saved Pictures. From here, you can share the image (by email, for instance), or synchronize it with the PC using the Zune software. Saving to other platforms It is of course possible to save to other platforms than the media library. For example, you can send the image to a web service, or save it to the isolated storage on the device. To do this, instead of using a MemoryStream, you can use any other stream (such as a web request stream, or a file stream) and save to that instead. Hopefully this code will be helpful to you!

• SharePoint 2010 PowerShell Script to Find All SPShellAdmins with Database Name

  - by Brian Jackett

  Problem     Yesterday on Twitter my friend @cacallahan asked for some help on how she could get all SharePoint 2010 SPShellAdmin users and the associated database name.  I spent a few minutes and wrote up a script that gets this information and decided I’d post it here for others to enjoy.     Background     The Get-SPShellAdmin commandlet returns a listing of SPShellAdmins for the given database Id you pass in, or the farm configuration database by default.  For those unfamiliar, SPShellAdmin access is necessary for non-admin users to run PowerShell commands against a SharePoint 2010 farm (content and configuration databases specifically).  Click here to read an excellent guest post article my friend John Ferringer (twitter) wrote on the Hey Scripting Guy! blog regarding granting SPShellAdmin access.  Solution     Below is the script I wrote (formatted for space and to include comments) to provide the information needed. Click here to download the script.   # declare a hashtable to store results $results = @{}   # fetch databases (only configuration and content DBs are needed) $databasesToQuery = Get-SPDatabase | Where {$_.Type -eq 'Configuration Database' -or $_.Type -eq 'Content Database'}   # for each database get spshelladmins and add db name and username to result $databasesToQuery | ForEach-Object {$dbName = $_.Name; Get-SPShellAdmin -database $_.id | ForEach-Object {$results.Add($dbName, $_.username)}}   # sort results by db name and pipe to table with auto sizing of col width $results.GetEnumerator() | Sort-Object -Property Name | ft -AutoSize     Conclusion     In this post I provided a script that outputs all of the SPShellAdmin users and the associated database names in a SharePoint 2010 farm.  Funny enough it actually took me longer to boot up my dev VM and PowerShell (~3 mins) than it did to write the first working draft of the script (~2 mins).  Feel free to use this script and modify as needed, just be sure to give credit back to the original author.  Let me know if you have any questions or comments.  Enjoy!         -Frog Out   Links PowerShell Hashtables http://technet.microsoft.com/en-us/library/ee692803.aspx SPShellAdmin Access Explained http://blogs.technet.com/b/heyscriptingguy/archive/2010/07/06/hey-scripting-guy-tell-me-about-permissions-for-using-windows-powershell-2-0-cmdlets-with-sharepoint-2010.aspx

• SQL Server-Determine which query is taking a long time to complete

  - by Neil Smith

  Cool little trick to determine which sql query which is taking a long time to execute, first while offending query is running from another machine do EXEC sp_who2 Locate the SPID responsible via Login, DBName and ProgramName columns, then do DBCC INPUTBUFFER (<SPID>) The offending query will be in the EventInfo column.  This is a great little time saver for me, before I found out about this I used to split my concatenated query script in to multiple sql files until I located the problem query

• Lessons Building KeyRef (a .NET developer learning Rails)

  - by Liam McLennan

  Just because I like to build things, and I like to learn, I have been working on a keyboard shortcut reference site. I am using this as an opportunity to improve my ruby and rails skills. The first few days were frustrating. Perhaps the learning curve of all the fun new toys was a bit excessive. Finally tonight things have really started to come together. I still don’t understand the rails built-in testing support but I will get there. Interesting Things I Learned Tonight RubyMine IDE Tonight I switched to RubyMine instead of my usual Notepad++. I suspect RubyMine is a powerful tool if you know how to use it – but I don’t. At the moment it gives me errors about some gems not being activated. This is another one of those things that I will get to. I have also noticed that the editor functions significantly differently to the editors I am used to. For example, in visual studio and notepad++ if you place the cursor at the start of a line and press left arrow the cursor is sent to the end of the previous line. In RubyMine nothing happens. Haml Haml is my favourite view engine. For my .NET work I have been using its non-union Mexican CLR equivalent – nHaml. Multiple CSS Classes To define a div with more than one css class haml lets you chain them together with a ‘.’, such as: .span-6.search_result contents of the div go here Indent Consistency I also learnt tonight that both haml and nhaml complain if you are not consistent about indenting. As a consequence of the move from notepad++ to RubyMine my haml views ended up with some tab indenting and some space indenting. For the view to render all of the indents within a view must be consistent. Sorting Arrays I guessed that ruby would be able to sort an array alphabetically by a property of the elements so my first attempt was: Application.all.sort {|app| app.name} which does not work. You have to supply a comparer (much like .NET). The correct sort is: Application.all.sort {|a,b| a.name.downcase <=> b.name.downcase} MongoMapper Find by Id Since document databases are just fancy key-value stores it is essential to be able to easily search for a document by its id. This functionality is so intrinsic that it seems that the MongoMapper author did not bother to document it. To search by id simply pass the id to the find method: Application.find(‘4c19e8facfbfb01794000002’) Rails And CoffeeScript I am a big fan of CoffeeScript so integrating it into this application is high on my priorities. My first thought was to copy Dr Nic’s strategy. Unfortunately, I did not get past step 1. Install Node.js. I am doing my development on Windows and node is unix only. I looked around for a solution but eventually had to concede defeat… for now. Quicksearch The front page of the application I am building displays a list of applications. When the user types in the search box I want to reduce the list of applications to match their search. A quick googlebing turned up quicksearch, a jquery plugin. You simply tell quicksearch where to get its input (the search textbox) and the list of items to filter (the divs containing the names of applications) and it just works. Here is the code: $('#app_search').quicksearch('.search_result'); Summary I have had a productive evening. The app now displays a list of applications, allows them to be sorted and links through to an application page when an application is selected. Next on the list is to display the set of keyboard shortcuts for an application.
