  • SQL Server 2008 Express + Reporting Services on Windows 7

    - by TimothyP
    I'm trying to install SQL Server Express 2008 and Reporting Services on a x64 Windows 7 Machine for development purposes. I've installed SQL Server 2008 Express with the Microsoft Web Platform Installer I had to manually enable the SQL Server Browser in the Sql Server Configuration Manager and tried to enable the SQL Server Agent but that simply doesn't work. Keeps throwing an RPC error: "The remote procedure call failed. [0x800706be]". The start mode is set to Disabled and I cannot change it. Even though I selected the SQL Server Express with advanced services in the web platform installer I could not find any reference to SQL Server Reporting Services so I used the SQL Server Installation Center x64 application to "upgrade" to SQL Server Express 2008 with advanced services... this installed many things but still I couldn't find any reference to SQL Server Reporting Services other than an application called: "Reporting Services Configuration Manager" This opens up a dialog called "Reporting Services Configuration Connection" which is asking for a server name (shows the name of my machine) and a Find button. When I click the find button I get: "Unable to connect to the Reporting Server WMI provider. Details: Invalid Namespace". I found some references on the web to solve this problem, but they refer to a directory: "%ProgamFiles%\Microsoft SQL Server\MSRS10.SQL2008\Reporting Services\" which does not exist anywhere on my system. (The directories for SQL Server are there, but there is no Reporting Services directory anywhere). What am I doing wrong here? Wasn't the web platform installer supposed to handle all this? Thnx for any advice. PS: Most google results refer to 2005 vs 2008 problems, but I never had 2005 installed on this system, it's a newly installed development machine.

  • Calling Web Services in classic ASP

    - by cabhilash
      Last day my colleague asked me the provide her a solution to call the Web service from classic ASP. (Yes Classic ASP. still people are using this :D ) We can call web service SOAP toolkit also. But invoking the service using the XMLHTTP object was more easier & fast. To create the Service I used the normal Web Service in .Net 2.0 with [Webmethod] public class WebService1 : System.Web.Services.WebService { [WebMethod] public string HelloWorld(string name){return name + " Pay my dues :) "; // a reminder to pay my consultation fee :D} } In Web.config add the following entry in System.web<webServices><protocols><add name="HttpGet"/><add name="HttpPost"/></protocols></webServices> Alternatively, you can enable these protocols for all Web services on the computer by editing the <protocols> section in Machine.config. The following example enables HTTP GET, HTTP POST, and also SOAP and HTTP POST from localhost: <protocols> <add name="HttpSoap"/> <add name="HttpPost"/> <add name="HttpGet"/> <add name="HttpPostLocalhost"/> <!-- Documentation enables the documentation/test pages --> <add name="Documentation"/> </protocols> By adding these entries I am enabling the HTTPGET & HTTPPOST (After .Net 1.1 by default HTTPGET & HTTPPOST is disabled because of security concerns)The .NET Framework 1.1 defines a new protocol that is named HttpPostLocalhost. By default, this new protocol is enabled. This protocol permits invoking Web services that use HTTP POST requests from applications on the same computer. This is true provided the POST URL uses http://localhost, not http://hostname. This permits Web service developers to use the HTML-based test form to invoke the Web service from the same computer where the Web service resides. Classic ASP Code to call Web service <%Option Explicit Dim objRequest, objXMLDoc, objXmlNode Dim strRet, strError, strNome Dim strName strName= "deepa" Set objRequest = Server.createobject("MSXML2.XMLHTTP") With objRequest .open "GET", "http://localhost:3106/WebService1.asmx/HelloWorld?name=" & strName, False .setRequestHeader "Content-Type", "text/xml" .setRequestHeader "SOAPAction", "http://localhost:3106/WebService1.asmx/HelloWorld" .send End With Set objXMLDoc = Server.createobject("MSXML2.DOMDocument") objXmlDoc.async = false Response.ContentType = "text/xml" Response.Write(objRequest.ResponseText) %> In Line 6 I created an MSXML XMLHTTP object. Line 9 Using the HTTPGET protocol I am openinig connection to WebService Line 10:11 – setting the Header for the service In line 15, I am getting the output from the webservice in XML Doc format & reading the responseText(line 18). In line 9 if you observe I am passing the parameter strName to the Webservice You can pass multiple parameters to the Web service by just like any other QueryString Parameters. In similar fashion you can invoke the Web service using HTTPPost. Only you have to ensure that the form contains all th required parameters for webmethod.  Happy coding !!!!!!!

  • SQL Server 2008 R2 upgrade fails on upgrade rule check

    - by Tim
    I'm trying to upgrade an evaluation instance of SQL Server 2008 to a fully licensed instance of SQL Server 2008 R2. I made it most of the way through the installer, but I'm getting stopped at the Upgrade Rules page - the SQL Server Analysis Services Upgrade Service Functional Check is failing. The specific error I get: Rule "SQL Server Analysis Services Upgrade Service Functional Check" failed. The current instance of the SQL Server Analysis Services service cannot be upgraded because the Analysis Services service is disabled or not online. Please start the service and then run the upgrade rules check again. Simple enough - just need to start the service. Here's where it gets troublesome. When I open Services and go to start the SQL Server Analysis Services (MSSQLSERVER) service, it provides me the following message: The SQL Server Analysis Services (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. Trying from the command line as Administrator yields: PS C:\Windows\System32 net start MSSQLServerOLAPService The SQL Server Analysis Services (MSSQLSERVER) service is starting... The SQL Server Analysis Services (MSSQLSERVER) service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. I've tried changing the logon setting of this service to Administrator, a user with admin privileges, and both the Local System and Network Service accounts - nothing works. In addition, when I look at the service through the SQL Server Configuration Manager (also run as Administrator), attempting to change the logon setting for the service results in the message: The server threw an exception. [0x80010105] I have no need for analysis services themselves - all I need is for this one service to be running long enough to do the R2 upgrade, then it can shut down again. Any thoughts on how to get the Analysis Services service running? Update: Checking the event log, I found an error logged to the Application log from the MSSQLServerOLAPService. It has event ID 0, task category (289), and says: The service cannot be started: XML parsing failed at line 1, column 4: Unrecognized input signature.

  • Microsoft SQL Server 2012 Analysis Services – The BISM Tabular Model #ssas #tabular #bism

    - by Marco Russo (SQLBI)
    I, Alberto and Chris spent many months (many nights, holidays and also working days of the last months) writing the book we would have liked to read when we started working with Analysis Services Tabular. A book that explains how to use Tabular, how to model data with Tabular, how Tabular internally works and how to optimize a Tabular model. All those things you need to start on a real project in order to make an happy customer. You know, we’re all consultants after all, so customer satisfaction is really important to be paid for our job! Now the book writing is finished, we’re in the final stage of editing and reviews and we look forward to get our print copy. Its title is very long: Microsoft SQL Server 2012 Analysis Services – The BISM Tabular Model. But the important thing is that you can already (pre)order it. This is the list of chapters: 01. BISM Architecture 02. Guided Tour on Tabular 03. Loading Data Inside Tabular 04. DAX Basics 05. Understanding Evaluation Contexts 06. Querying Tabular 07. DAX Advanced 08. Understanding Time Intelligence in DAX 09. Vertipaq Engine 10. Using Tabular Hierarchies 11. Data modeling in Tabular 12. Using Advanced Tabular Relationships 13. Tabular Presentation Layer 14. Tabular and PowerPivot for Excel 15. Tabular Security 16. Interfacing with Tabular 17. Tabular Deployment 18. Optimization and Monitoring And this is the book cover – have a good read!

  • Patterns & Practices: Composite Services CTP2 is Public

    - by HernanDL
    Finally the last CTP and pre-release version for the Composite Services is out. There were quite a lot of changes since CTP1. We added many new samples and many enhancements to the repository (DB) which is now called Inventory in sync with SOA Patterns. Here is a brief list of the main changes according to the included documentations.   Changes and additions in this release This CTP release contains reusable source code and samples to illustrate implementation for the following patterns and scenarios: Repair and Resubmit – this pattern is implemented in ESB Toolkit 2.0 as part of Exception Management Framework (EMF). This code drop provides code sample how to implement this pattern for Windows AppFabric workflow service, using Exceptions Web Service and workflow activities to create fault message, which will be created in EMF database.  Analytic Tracing – this code drop contains reusable code and samples for implementing ETW tracing: event collector service and database that store collected events. This capability may be used for scenarios that need flexibility on how collected events are decoded and processed via extensibility points you can configure and implement:  plugins and event decoders with leveraging ETW tracing capabilities provided by the event collector service.   Inventory Centralization – this code drop contains service catalog database, web services and samples to show how to implement Metadata Centralization, Schema Centralization and Policy Centralization patterns.  Service Virtualization – we included sample for implementing this pattern using WCF routing service( which is part of .NET framework) and service metadata centralization capabilities to define routing service metadata in service catalog. Termination Notification – we included sample for implementing this pattern using sample WCF service and policy centralization capabilities provided by this CTP release.   You will also find many new videos that will be uploaded to the home page any time soon. Stay tunned for new posts regarding implemetation details and advanced customizations for custom policy exporters/importers and monitoring.

  • Websockets Server with Fault-Tolerance and Durable Message Store

    - by smitchell360
    I am starting to experiment with websockets. Does anyone know of a websockets server (open source or paid) that provides a durable store of the websocket "channel"? All of the examples that I have found do not address durability -- if a websockets server goes down, all "channel" data is lost. Services such as Pusher do not really discuss whether they address the durability issue (and I have not received a response from tech support yet). Happy to roll my own, but would rather not reinvent the wheel. EDIT: I'm not looking for websockets 101 information. That is readily available and understood. I'm looking for a server (open source or paid) that supports websockets and has a durable store for the websocket data so that, in the event that a server fails, a new server can take over where the original one left off. Two main purposes: 1. support failover scenarios contemplated by the websockets Network Working Group http://tools.ietf.org/html/draft-ibc-websocket-dns-srv-02#section-5.1 (most importantly so that missed messages are sent when a client connects to a failover server) 2. support scenarios where new subscribers must receive all past messages that were published. Of course this can be handled at the application layer...but that is not what I am looking for. EDIT So, after some research the following installed options seem to be the most robust: Kaazing Migratory Migratory (http://migratory.ro) Hosted services that seem "real" Pusher (great API but no history feature yet) PubNub (has history) All of the above services have graceful fallback to other communication methods if websockets are not available. I was not able to find any open source that provided "out of the box" clustering, fail-over, and a durable message store to play back history. There are some projects that may serve as good starting points, but not exactly what I am looking for.

  • Write DAX queries in Report Builder #ssrs #dax #ssas #tabular

    - by Marco Russo (SQLBI)
    If you use Report Builder with Reporting Services, you can use DAX queries even if the editor for Analysis Services provider does not support DAX syntax. In fact, the DMX editor that you can use in Visual Studio editor of Reporting Services (see a previous post on that), is not available in Report Builder. However, as Sagar Salvi commented in this Microsoft Connect entry, you can use the DAX query text in the query of a Dataset by using the OLE DB provider instead of the Analysis Services one. I think it’s a good idea to show the steps required. First, create a DataSet using the OLE DB connection type, and provide the connection string the provider (Provider), the server name (Data Source) and the database name (Initial Catalog), such as: Provider=MSOLAP;Data Source=SERVERNAME\\TABULAR;Initial Catalog=AdventureWorks Tabular Model SQL 2012 Then, create a Dataset using the data source previously defined, select the Text query type, and write the DAX code in the Query pane: You can also use the Query Designer window, that doesn’t provide any particular help in writing the DAX query, but at least can show a preview of the result of the query execution. I hope DAX will get better editors in the future… in the meantime, remember you can use DAX Studio to write and test your DAX queries, and DAX Formatter to improve their readability!If you want to learn the DAX Query Language, I suggest you watching my video Data Analysis Expressions as a Query Language on Project Botticelli!

  • Interview questions about ASP.NET Web services.

    - by Jalpesh P. Vadgama
    I have seen there are lots of myth’s about asp.net web services in fresher level asp.net developers. So I decided to write a blog post about asp.net web services interview questions. Because I think this is the best way to reach fresher asp.net developers. Followings are few questions about asp.net web services. 1) What is asp.net web services? Ans: Web services are used to support http requests that formatted using xml,http and SOAP syntax. They interact with through standards xml messages through Soap. They are used to support interoperability. It has .asmx extension and .NET framework contains http handlers for web services to support http requested directly. 2) What kind of data can be returned web services web methods? Ans: It supports all the primitive data types and custom data types that can be encoded and serialized by xml. You can find more information about that from the following link. http://msdn.microsoft.com/en-us/library/bb552900.aspx 3) Is web services are only written in asp.net? Ans: No, It can be written by Java and PHP languages also. 4) Explain web method attributes in web services Ans: Web method attributes are added to a public class method to indicate that this method is exposed as a part of XML web services. You can have multiple web methods in a class. But it should be having public attributes as it will be exposed as xml web service part. You can find more information about web method attributes from following link. http://msdn.microsoft.com/en-us/library/byxd99hx(v=vs.71).aspx 5) What is SOA? Ans: SOA stands for “Services Oriented Architecture”. It is kind of service oriented architecture used to support different kind of computing platforms and applications. Web services in asp.net are one of the technologies that supports that kind of architecture.  You can call asp.net web services from any computing platforms and applications. 6) What is SOAP,WDSL and UDDI? Ans: SOAP stands “Simple Object Access protocol”. Web services will be interact with SOAP messages written in XML. SOAP is sometimes referred as “data wrapper” or “data envelope”.Its contains different xml tag that creates a whole SOAP message.  WSDL stand for “Web services Description Language”.  It is an xml document which is written according to standard specified by W3c. It is a kind of manual or document that describes how we can use and consume web service. Web services development software processes the WSDL document and generates SOAP messages that are needed for specific web service. UDDI stand for “Universal Discovery, Description and Integration”. Its is used for web services registries. You can find addresses of web services from UDDI.

  • Connecting to Magento Web Services with Java

    - by kerry
    I was in the unenviable position of needing to connect to Magento, a PHP ecommerce platform, web services using Java.  It was kind of difficult to get the classes generated from the WSDL so I figured I would throw the results up on my github account for any other poor sap in a similar position. First, pull down the project using git: git clone git://github.com/webdevwilson/magento-java.git and build it with maven: mvn install Here is a quick example of how to pull an order using the generated classes: MagentoServiceLocator serviceLocator = new MagentoServiceLocator(); String url = "http://domain.com/index.php/api/v2_soap"; Mage_Api_Model_Server_V2_HandlerPortType port = serviceLocator.getMage_Api_Model_Server_V2_HandlerPort(url); String sessionId = port.login("username", "key"); SalesOrderEntity salesOrder = port.salesOrderInfo(sessionId, orderId); I also have some wrapper code in there that makes it a little easier to call the API. Checkout the project at https://github.com/webdevwilson/magento-java There is another option. it’s called Magja and it is located at google code.

  • WCF data services - Limiting related objects returned based on critera

    - by Mike Morley
    I have an object graph consisting of a base employee object, and a set of related message objects. I am able to return the employee objects based on search criteria on the employee properties (eg team) etc. However, if I expand on the messages, I get the full collection of messages back. I would like to be able to either take the top n messages (i.e. restrict to 10 most recent) or ideally use a date range on the message objects to limit how many are brought back. So far I have not been able to figure out a way of doing this: I get an error if I attempt to filter on properties on the message (&$filter=employee/message/StartDate gives an error "No property 'StartDate' exists in type 'System.Data.Objects.DataClasses.EntityCollection`1). Attempting to use Top on the message related object doesn't work either. I have also tried using a WebGet extension that takes a string list of employee IDs. That works until the list gets too long, and then fails due to the URL getting too long (it might be possible to setup a paging mechanism on this approach)... Unfortunately the UI control I am using requires the data to be in a fairly specific hierarchical shape, so I can't easily come at this from starting on the message side and working backwards. Outside of making multiple calls does anyone know of a method to accomplish this with wcf data services? Thanks! M.

  • Implementing a generic repository for WCF data services

    - by cibrax
    The repository implementation I am going to discuss here is not exactly what someone would call repository in terms of DDD, but it is an abstraction layer that becomes handy at the moment of unit testing the code around this repository. In other words, you can easily create a mock to replace the real repository implementation. The WCF Data Services update for .NET 3.5 introduced a nice feature to support two way data bindings, which is very helpful for developing WPF or Silverlight based application but also for implementing the repository I am going to talk about. As part of this feature, the WCF Data Services Client library introduced a new collection DataServiceCollection<T> that implements INotifyPropertyChanged to notify the data context (DataServiceContext) about any change in the association links. This means that it is not longer necessary to manually set or remove the links in the data context when an item is added or removed from a collection. Before having this new collection, you basically used the following code to add a new item to a collection. Order order = new Order {   Name = "Foo" }; OrderItem item = new OrderItem {   Name = "bar",   UnitPrice = 10,   Qty = 1 }; var context = new OrderContext(); context.AddToOrders(order); context.AddToOrderItems(item); context.SetLink(item, "Order", order); context.SaveChanges(); Now, thanks to this new collection, everything is much simpler and similar to what you have in other ORMs like Entity Framework or L2S. Order order = new Order {   Name = "Foo" }; OrderItem item = new OrderItem {   Name = "bar",   UnitPrice = 10,   Qty = 1 }; order.Items.Add(item); var context = new OrderContext(); context.AddToOrders(order); context.SaveChanges(); In order to use this new feature, you first need to enable V2 in the data service, and then use some specific arguments in the datasvcutil tool (You can find more information about this new feature and how to use it in this post). DataSvcUtil /uri:"http://localhost:3655/MyDataService.svc/" /out:Reference.cs /dataservicecollection /version:2.0 Once you use those two arguments, the generated proxy classes will use DataServiceCollection<T> rather than a simple ObjectCollection<T>, which was the default collection in V1. There are some aspects that you need to know to use this feature correctly. 1. All the entities retrieved directly from the data context with a query track the changes and report those to the data context automatically. 2. A entity created with “new” does not track any change in the properties or associations. In order to enable change tracking in this entity, you need to do the following trick. public Order CreateOrder() {   var collection = new DataServiceCollection<Order>(this.context);   var order = new Order();   collection.Add(order);   return order; } You basically need to create a collection, and add the entity to that collection with the “Add” method to enable change tracking on that entity. 3. If you need to attach an existing entity (For example, if you created the entity with the “new” operator rather than retrieving it from the data context with a query) to a data context for tracking changes, you can use the “Load” method in the DataServiceCollection. var order = new Order {   Id = 1 }; var collection = new DataServiceCollection<Order>(this.context); collection.Load(order); In this case, the order with Id = 1 must exist on the data source exposed by the Data service. Otherwise, you will get an error because the entity did not exist. These cool extensions methods discussed by Stuart Leeks in this post to replace all the magic strings in the “Expand” operation with Expression Trees represent another feature I am going to use to implement this generic repository. Thanks to these extension methods, you could replace the following query with magic strings by a piece of code that only uses expressions. Magic strings, var customers = dataContext.Customers .Expand("Orders")         .Expand("Orders/Items") Expressions, var customers = dataContext.Customers .Expand(c => c.Orders.SubExpand(o => o.Items)) That query basically returns all the customers with their orders and order items. Ok, now that we have the automatic change tracking support and the expression support for explicitly loading entity associations, we are ready to create the repository. The interface for this repository looks like this,public interface IRepository { T Create<T>() where T : new(); void Update<T>(T entity); void Delete<T>(T entity); IQueryable<T> RetrieveAll<T>(params Expression<Func<T, object>>[] eagerProperties); IQueryable<T> Retrieve<T>(Expression<Func<T, bool>> predicate, params Expression<Func<T, object>>[] eagerProperties); void Attach<T>(T entity); void SaveChanges(); } The Retrieve and RetrieveAll methods are used to execute queries against the data service context. While both methods receive an array of expressions to load associations explicitly, only the Retrieve method receives a predicate representing the “where” clause. The following code represents the final implementation of this repository.public class DataServiceRepository: IRepository { ResourceRepositoryContext context; public DataServiceRepository() : this (new DataServiceContext()) { } public DataServiceRepository(DataServiceContext context) { this.context = context; } private static string ResolveEntitySet(Type type) { var entitySetAttribute = (EntitySetAttribute)type.GetCustomAttributes(typeof(EntitySetAttribute), true).FirstOrDefault(); if (entitySetAttribute != null) return entitySetAttribute.EntitySet; return null; } public T Create<T>() where T : new() { var collection = new DataServiceCollection<T>(this.context); var entity = new T(); collection.Add(entity); return entity; } public void Update<T>(T entity) { this.context.UpdateObject(entity); } public void Delete<T>(T entity) { this.context.DeleteObject(entity); } public void Attach<T>(T entity) { var collection = new DataServiceCollection<T>(this.context); collection.Load(entity); } public IQueryable<T> Retrieve<T>(Expression<Func<T, bool>> predicate, params Expression<Func<T, object>>[] eagerProperties) { var entitySet = ResolveEntitySet(typeof(T)); var query = context.CreateQuery<T>(entitySet); foreach (var e in eagerProperties) { query = query.Expand(e); } return query.Where(predicate); } public IQueryable<T> RetrieveAll<T>(params Expression<Func<T, object>>[] eagerProperties) { var entitySet = ResolveEntitySet(typeof(T)); var query = context.CreateQuery<T>(entitySet); foreach (var e in eagerProperties) { query = query.Expand(e); } return query; } public void SaveChanges() { this.context.SaveChanges(SaveChangesOptions.Batch); } } For instance, you can use the following code to retrieve customers with First name equal to “John”, and all their orders in a single call. repository.Retrieve<Customer>(    c => c.FirstName == “John”, //Where    c => c.Orders.SubExpand(o => o.Items)); In case, you want to have some pre-defined queries that you are going to use across several places, you can put them in an specific class. public static class CustomerQueries {   public static Expression<Func<Customer, bool>> LastNameEqualsTo(string lastName)   {     return c => c.LastName == lastName;   } } And then, use it with the repository. repository.Retrieve<Customer>(    CustomerQueries.LastNameEqualsTo("foo"),    c => c.Orders.SubExpand(o => o.Items));

  • ADO.NET (WCF) Data Services Query Interceptor Hangs IIS

    - by PreMagination
    I have an ADO.NET Data Service that's supposed to provide read-only access to a somewhat complex database. Logically I have table-per-type (TPT) inheritance in my data model but the EDM doesn't implement inheritance. (Limitation of EF and navigation properties on derived types. STILL not fixed in EF4!) I can query my EDM directly (using a separate project) using a copy of the query I'm trying to run against the web service, results are returned within 10 seconds. Disabling the query interceptors I'm able to make the same query against the web service, results are returned similarly quickly. I can enable some of the query interceptors and the results are returned slowly, up to a minute or so later. Alternatively, I can enable all the query interceptors, expand less of the properties on the main object I'm querying, and results are returned in a similar period of time. (I've increased some of the timeout periods) Up til this point Sql Profiler indicates the slow-down is the database. (That's a post for a different day) But when I enable all my query interceptors and expand all the properties I'd like to have the IIS worker process pegs the CPU for 20 minutes and a query is never even made against the database. This implies to me that yes, my implementation probably sucks but regardless the Data Services "tier" is having an issue it shouldn't. WCF tracing didn't reveal anything interesting to my untrained eye. Details: Data model: Agent-Person-Student Student has a collection of referrals Students and referrals are private, queries against the web service should only return "your" students and referrals. This means Person and Agent need to be filtered too. Other entities (Agent-Organization-School) can be accessed by anyone who has authenticated. The existing security model is poorly suited to perform this type of filtering for this type of data access, the query interceptors are complicated and cause EF to generate some entertaining sql queries. Sample Interceptor [QueryInterceptor("Agents")] public Expression<Func<Agent, Boolean>> OnQueryAgents() { //Agent is a Person(1), Educator(2), Student(3), or Other Person(13); allow if scope permissions exist return ag => (ag.AgentType.AgentTypeId == 1 || ag.AgentType.AgentTypeId == 2 || ag.AgentType.AgentTypeId == 3 || ag.AgentType.AgentTypeId == 13) && ag.Person.OrganizationPersons.Count<OrganizationPerson>(op => op.Organization.ScopePermissions.Any<ScopePermission> (p => p.ApplicationRoleAccount.Account.UserName == HttpContext.Current.User.Identity.Name && p.ApplicationRoleAccount.Application.ApplicationId == 124) || op.Organization.HierarchyDescendents.Any<OrganizationsHierarchy>(oh => oh.AncestorOrganization.ScopePermissions.Any<ScopePermission> (p => p.ApplicationRoleAccount.Account.UserName == HttpContext.Current.User.Identity.Name && p.ApplicationRoleAccount.Application.ApplicationId == 124))) > 0; } The query interceptors for Person, Student, Referral are all very similar, ie they traverse multiple same/similar tables to look for ScopePermissions as above. Sample Query var referrals = (from r in service.Referrals .Expand("Organization/ParentOrganization") .Expand("Educator/Person/Agent") .Expand("Student/Person/Agent") .Expand("Student") .Expand("Grade") .Expand("ProblemBehavior") .Expand("Location") .Expand("Motivation") .Expand("AdminDecision") .Expand("OthersInvolved") where r.DateCreated >= coupledays && r.DateDeleted == null select r); Any suggestions or tips would be greatly associated, for fixing my current implementation or in developing a new one, with the caveat that the database can't be changed and that ultimately I need to expose a large portion of the database via a web service that limits data access to the data authorized for, for the purpose of data integration with multiple outside parties. THANK YOU!!!

  • Windows Azure Mobile Services Updates Keep Coming

    - by Clint Edmonson
    Some exciting new Windows Azure Mobile Services features were delivered to production this week. The highlights include: iPhone and iPad connectivity support via a new iOS SDK Integrated Authentication so developers can configure user authentication via Microsoft Account, Facebook, Twitter, and Google. New server-side Mobile Service script modules Access to Structured Storage, Windows Azure Blob, Table, Queues, and ServiceBus Email services through partnership with SendGrid SMS & voice services through partnership with Twilio Mobile Services hosting expanded to west coast US The iOS SDK I’m excited to share that we've announced the release of an under-development iOS client SDK for Windows Azure Mobile Services. The iOS SDK joins the Windows 8 SDK launched with Windows Azure Mobile Services as well as client SDKs released by Xamarin for MonoTouch and MonoDroid.  The native iOS SDK is for developers programming in Objective-C on the iPhone and iPad platforms. The SDK gives developers the same level of access to data storage using dynamic schematization that is available for Windows 8. Also, iOS applications can use the same authentication options available in Mobile Services. While full iOS support is still in development, the libraries are currently available on GitHub. There’s a great getting started tutorial to walk you through building a simple iOS “Todo List” app that stores data in Windows Azure.  These additional tutorials explore how to use the iOS client libraries to store data and authenticate users: Get Started with data in Mobile Services for iOS Get Started with authentication in Mobile Services for iOS What’s New in Authentication Available to both iOS and Windows 8 developers, Mobile Services has expanded its authentication options.  Developers can now use Microsoft, Facebook, Twitter, and Google authentication. Similar to using Microsoft accounts for authentication, developers must sign up and through Facebook, Twitter, or Google's developer portal in order to authenticate through them.  These tutorials walk through how to register your Mobile Service with an identity provider: How to register your app with Microsoft Account How to register your app with Facebook How to register your app with Twitter How to register your app with Google And these tutorials walk through authenticating against Mobile Services: Get started with authentication in Mobile Services for Windows Store (C#) Get started with authentication in Mobile Services for Windows Store (JavaScript) Get started with authentication in Mobile Services for iOS What’s New in Mobile Service Scripts Some great new functionality is now available in the Mobile Service script layer.  These server side scripts are triggered off of any CRUD operation on a Mobile Service's table and can already handle doing data and query validation, filtering, web requests and more.  Today, the Azure SDK module is now available to these scripts giving them access to blob storage, service bus, table storage.  Check out the new tutorials on the Windows Azure Node.js developer center to learn more about working with Blob, Tables, Queues and Service Bus using the azure module. In addition, SendGrid and Twilio are now available via modules that can be called from the scripts as well.  This gives developers the ability to send emails (SendGrid) or SMS text messages (Twilio) whenever a script is fired.  Windows Azure customers receive a special offer of 25,000 free emails per month from SendGrid and 1000 free text messages from Twilio. Expanded Data Center Availability In addition to Mobile Services being available in our US East data center, they can now be spun up in US West. The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. The Windows Azure Mobile Developer Center has been updated with new tutorials that cover these new features in detail. And don’t forget - Windows Azure Mobile Services are still free for your first ten applications running on shared compute instances. Stay tuned to my twitter feed for Windows Azure announcements, updates, and links: @clinted

  • Application losing Printer within Terminal Services for remote users

    - by Richard
    Question: What I need to do is have a permanent link to a printer, normally only accessible through Terminal Services (Printer Redirect), to allow Sage Line 50 layouts to see that printer persistently, even after users have disconnected and reconnected to the Terminal Services session? Although the printer is accessible each time a user connects to the Sage Server via Terminal Services, it is given a different session number and therefore the Sage Layout sees it as a different printer. History behind question: Users using Terminal Services connecting to a Sage Server on a different site Using Sage Line 50 v 15 on that Server Users want to print invoices (sage layouts) locally Sage Server cannot see the users local printers, to get around this user uses the Print redirect features of Terminal Services The individual reports can be edited to point to a specific printer by default. This means the user just has to select an invoice and click print, then select the layout/report wanted and it auto prints that invoice to the default printer specified. The problem occurs because the layouts are edited to point to the users local printer "Ricoh 1018d (session#)", note the "(session#)" as this is the users local printer being redirected through the terminal services session. Users are able to print using the sage layouts once the default printer is setup within the layout and saved, but as soon as the users disconnects from the Terminal Services session and then reconnect in the morning go to print, it has lost the connection to that printer. I understand why its failed, because that the printer is on a per session basis and the layout would not be able to hold on to the connection from a previous session. Thanks in advance for any assistance...

  • How to restrict file system when logged into terminal services

    - by pghcpa
    What I need to accomplish: With one login, when user is physically in the building I need them to see everything. When they are using terminal services with same login they should not be able to see the file system on the network. I can lock down the PC running terminal services as that is its only use. Details: Windows/2003 Server with terminal services. One login for a user (e.g., johndoe). When johndoe logs into the network at his desk in the office, he can see the network files according to group policy. When johndoe logs into terminal services from outside the building, we do not want to allow him see the network. Using 2x to do a published app, but that app has a "feature" that allows user to see network. Published application on termina services (only) is a document management system that is tied to windows login, so I can't give them two logins. With one login, when they are in the building I need them to see everything. When they are using terminal services they should not be able to see the network. I can lock down the PC running terminal services as that is its only use.

  • Benefits of PerformancePoint Services Using SharePoint Server 2010

    - by Wayne
    What is PerformancePoint Services? Most of the time it happens that the metrics that make up your key performance indicators are not simple values from a data source. In SharePoint Server 2007 PerformancePoint Services, you could create two kinds of KPI metrics: Simple single value metrics from any supported data source or Complex multiple value metrics from a single Analysis Services data source using MDX. Now things are even easier with Performance Point Services in SharePoint 2010. Let us check what is it? PerformancePoint Services in SharePoint Server 2010 is a performance management service that you can use to monitor and analyze your business. By providing flexible, easy-to-use tools for building dashboards, scorecards, reports, and key performance indicators (KPIs), PerformancePoint Services can help everyone across an organization make informed business decisions that align with companywide objectives and strategy. Scorecards, dashboards, and KPIs help drive accountability. Integrated analytics help employees move quickly from monitoring information to analyzing it and, when appropriate, sharing it throughout the organization. Prior to the addition of PerformancePoint Services to SharePoint Server, Microsoft Office PerformancePoint Server 2007 functioned as a standalone server. Now PerformancePoint functionality is available as an integrated part of the SharePoint Server Enterprise license, as is the case with Excel Services in Microsoft SharePoint Server 2010. The popular features of earlier versions of PerformancePoint Services are preserved along with numerous enhancements and additional functionality. New PerformancePoint Services features PerformancePoint Services now can utilize SharePoint Server scalability, collaboration, backup and recovery, and disaster recovery capabilities. Dashboards and dashboard items are stored and secured within SharePoint lists and libraries, providing you with a single security and repository framework. New features and enhancements of SharePoint 2010 PerformancePoint Services • With PerformancePoint Services, functioning as a service in SharePoint Server, dashboards and dashboard items are stored and secured within SharePoint lists and libraries, providing you with a single security and repository framework. The new architecture also takes advantage of SharePoint Server scalability, collaboration, backup and recovery, and disaster recovery capabilities. You also can include and link PerformancePoint Services Web Parts with other SharePoint Server Web Parts on the same page. The new architecture also streamlines security models that simplify access to report data. • The Decomposition Tree is a new visualization report type available in PerformancePoint Services. You can use it to quickly and visually break down higher-level data values from a multi-dimensional data set to understand the driving forces behind those values. The Decomposition Tree is available in scorecards and analytic reports and ultimately in dashboards. • You can access more detailed business information with improved scorecards. Scorecards have been enhanced to make it easy for you to drill down and quickly access more detailed information. PerformancePoint scorecards also offer more flexible layout options, dynamic hierarchies, and calculated KPI features. Using this enhanced functionality, you can now create custom metrics that use multiple data sources. You can also sort, filter, and view variances between actual and target values to help you identify concerns or risks. • Better Time Intelligence filtering capabilities that you can use to create and use dynamic time filters that are always up to date. Other improved filters improve the ability for dashboard users to quickly focus in on information that is most relevant. • Ability to include and link PerformancePoint Services Web Parts together with other PerformancePoint Services Web parts on the same page. • Easier to author and publish dashboard items by using Dashboard Designer. • SQL Server Analysis Services 2008 support. • Increased support for accessibility compliance in individual reports and scorecards. • The KPI Details report is a new report type that displays contextually relevant information about KPIs, metrics, rows, columns, and cells within a scorecard. The KPI Details report works as a Web part that links to a scorecard or individual KPI to show relevant metadata to the end user in SharePoint Server. This Web part can be added to PerformancePoint dashboards or any SharePoint Server page. • Create analytics reports to better understand underlying business forces behind the results. Analytic reports have been enhanced to support value filtering, new chart types, and server-based conditional formatting. To conclude, PerformancePoint Services, by becoming tightly integrated with SharePoint Server 2010, takes advantage of many enterprise-level SharePoint Server 2010 features. Unfortunately, SharePoint Foundation 2010 doesn’t include this feature. There are still many choices in SharePoint family of products that include SharePoint Server 2010, SharePoint Foundation, SharePoint Server 2007 and associated free SharePoint web parts and templates.

  • SQL SERVER – Data Sources and Data Sets in Reporting Services SSRS

    - by Pinal Dave
    This example is from the Beginning SSRS by Kathi Kellenberger. Supporting files are available with a free download from the www.Joes2Pros.com web site. This example is from the Beginning SSRS. Supporting files are available with a free download from the www.Joes2Pros.com web site. Connecting to Your Data? When I was a child, the telephone book was an important part of my life. Maybe I was just a nerd, but I enjoyed getting a new book every year to page through to learn about the businesses in my small town or to discover where some of my school acquaintances lived. It was also the source of maps to my town’s neighborhoods and the towns that surrounded me. To make a phone call, I would need a telephone number. In order to find a telephone number, I had to know how to use the telephone book. That seems pretty simple, but it resembles connecting to any data. You have to know where the data is and how to interact with it. A data source is the connection information that the report uses to connect to the database. You have two choices when creating a data source, whether to embed it in the report or to make it a shared resource usable by many reports. Data Sources and Data Sets A few basic terms will make the upcoming choses make more sense. What database on what server do you want to connect to? It would be better to just ask… “what is your data source?” The connection you need to make to get your reports data is called a data source. If you connected to a data source (like the JProCo database) there may be hundreds of tables. You probably only want data from just a few tables. This means you want to write a specific query against this data source. A query on a data source to get just the records you need for an SSRS report is called a Data Set. Creating a local Data Source You can connect embed a connection from your report directly to your JProCo database which (let’s say) is installed on a server named Reno. If you move JProCo to a new server named Tampa then you need to update the Data Set. If you have 10 reports in one project that were all pointing to the JProCo database on the Reno server then they would all need to be updated at once. It’s possible to make a project level Data Source and have each report use that. This means one change can fix all 10 reports at once. This would be called a Shared Data Source. Creating a Shared Data Source The best advice I can give you is to create shared data sources. The reason I recommend this is that if a database moves to a new server you will have just one place in Report Manager to make the server name change. That one change will update the connection information in all the reports that use that data source. To get started, you will start with a fresh project. Go to Start > All Programs > SQL Server 2012 > Microsoft SQL Server Data Tools to launch SSDT. Once SSDT is running, click New Project to create a new project. Once the New Project dialog box appears, fill in the form, as shown in. Be sure to select Report Server Project this time – not the wizard. Click OK to dismiss the New Project dialog box. You should now have an empty project, as shown in the Solution Explorer. A report is meant to show you data. Where is the data? The first task is to create a Shared Data Source. Right-click on the Shared Data Sources folder and choose Add New Data Source. The Shared Data Source Properties dialog box will launch where you can fill in a name for the data source. By default, it is named DataSource1. The best practice is to give the data source a more meaningful name. It is possible that you will have projects with more than one data source and, by naming them, you can tell one from another. Type the name JProCo for the data source name and click the Edit button to configure the database connection properties. If you take a look at the types of data sources you can choose, you will see that SSRS works with many data platforms including Oracle, XML, and Teradata. Make sure SQL Server is selected before continuing. For this post, I am assuming that you are using a local SQL Server and that you can use your Windows account to log in to the SQL Server. If, for some reason you must use SQL Server Authentication, choose that option and fill in your SQL Server account credentials. Otherwise, just accept Windows Authentication. If your database server was installed locally and with the default instance, just type in Localhost for the Server name. Select the JProCo database from the database list. At this point, the connection properties should look like. If you have installed a named instance of SQL Server, you will have to specify the server name like this: Localhost\InstanceName, replacing the InstanceName with whatever your instance name is. If you are not sure about the named instance, launch the SQL Server Configuration Manager found at Start > All Programs > Microsoft SQL Server 2012 > Configuration Tools. If you have a named instance, the name will be shown in parentheses. A default instance of SQL Server will display MSSQLSERVER; a named instance will display the name chosen during installation. Once you get the connection properties filled in, click OK to dismiss the Connection Properties dialog box and OK again to dismiss the Shared Data Source properties. You now have a data source in the Solution Explorer. What’s next I really need to thank Kathi Kellenberger and Rick Morelan for sharing this material for this 5 day series of posts on SSRS. To get really comfortable with SSRS you will get to know the different SSDT windows, Build reports on your own (without the wizards),  Add report headers and footers, Accept user input,  create levels, charts, or even maps for visual appeal. You might be surprise to know a small 230 page book starts from the very beginning and covers the steps to do all these items. Beginning SSRS 2012 is a small easy to follow book so you can learn SSRS for less than $20. See Joes2Pros.com for more on this and other books. If you want to learn SSRS in easy to simple words – I strongly recommend you to get Beginning SSRS book from Joes 2 Pros.

  • Preloading multiple comboboxes/listbox itemssource with enumerated values using WCF RIA Services

    - by Dale Halliwell
    I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?
