  • Good practice on Visual Studio Solutions

    - by JonWillis
    Hopefully a relativity simple question. I'm starting work on a new internal project to create tractability of repaired devices within the buildings. The database is stored remotely on a webserver, and will be accessed via web API (JSON output) and protected with OAuth. The front end GUI is being done in WPF, and the business code in C#. From this, I see the different layers Presentation/Application/Datastore. There will be code for managing all the authenticated calls to the API, class to represent entities (business objects), classes to construct the entities (business objects), parts for WPF GUI, parts of the WPF viewmodels, and so on. Is it best to create this in a single project, or split them into individual projects? In my heart I say it should be multiple projects. I have done it both ways previously, and found testing to be easier with a single project solution, however with multiple projects then recursive dependencies can crop up. Especially when classes have interfaces to make it easier to test, I've found things can become awkward.

  • Visual Basic 2010 Language Enhancements

    Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10 (also referred to as Visual Basic 2010). Previously, the C# and Visual Basic programming languages were managed by two separate teams within Microsoft, which helps explain why features found in one language was not necessarily found in the other. For example, C# 3.0 introduced collection initializers, which enable developers to define the contents of a collection when declaring it; however, Visual Basic 9 did not support collection initializers. Conversely, Visual Basic has long supported optional parameters in methods, whereas C# did not. Recently, Microsoft merged the Visual Basic and C# teams to help ensure that C# and Visual Basic grow together. As explained by Microsoft program manager Jonathan Aneja, "The intent is to make the languages advance together. When major functionality is introduced in one language, it should appear in the other as well. ... [T]hat any task you can do in one language should be as simple in the other." To this end, with version 4.0 C# now supports optional parameters and named arguments, two features that have long been part of Visual Basic's vernacular. And, likewise, Visual Basic has been updated to include a number of C# features that it was previously missing. This article explores some of these new features that were added to Visual Basic 2010. Read on to learn more! Read More >Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Now Available: Visual Studio 2010 Release Candidate Virtual Machines with Sample Data and Hands-on-L

    - by John Alexander
    From a message from Brian Keller: “Back in December we posted a set of virtual machines pre-configured with Visual Studio 2010 Beta 2, Visual Studio Team Foundation Server 2010 Beta 2, and 7 hands-on-labs. I am pleased to announce that today we have shipped an updated virtual machine using the Visual Studio 2010 Release Candidate bits, a brand new sample application, and 9 hands-on-labs. This VM is customer-ready and includes everything you need to learn and/or deliver demonstrations of many of my favorite application lifecycle management (ALM) capabilities in Visual Studio 2010. This VM is available in the virtualization platform of your choice (Hyper-V, Virtual PC 2007 SP1, and Windows [7] Virtual PC). Hyper-V is highly recommended because of the performance benefits and snapshotting capabilities. Tailspin Toys The sample application we are using in this virtual machine is a simple ASP.NET MVC 2 storefront called Tailspin Toys. Tailspin Toys sells model airplanes and relies on the application lifecycle management capabilities of Visual Studio 2010 to help them build, test, and maintain their storefront. Major kudos go to Dan Massey for building out this great application for us. Hands-on-Labs / Demo Scripts The 9 hands-on-labs / demo scripts which accompany this virtual machine cover several of the core capabilities of conducting application lifecycle management with Visual Studio 2010. Each document can be used by an individual in a hands-on-lab capacity, to learn how to perform a given set of tasks, or used by a presenter to deliver a demonstration or classroom-style training. Unlike the beta 2 release, 100% of these labs target Tailspin Toys to help ensure a consistent storytelling experience.

  • Monitoring Visual Studio 2010 Performance Problems

    - by TATWORTH
    At http://visualstudiogallery.msdn.microsoft.com/fa85b17d-3df2-49b1-bee6-71527ffef441, Microsoft have provided a tool for Visual Studio to provide reports on Visual Studio 2010 performance problems. The use of it has been discussed at http://blogs.msdn.com/b/visualstudio/archive/2011/05/02/perfwatson.aspx as follows: "Would you like Visual Studio 2010 to be even faster? Would you like any performance issue you see to be  reported automatically without any hassle? Well now you can, with the new Visual Studio PerfWatson extension! Install this extension and help us deliver a faster Visual Studio experience. We’re constantly working to improve the performance of Visual Studio and take feedback about it very seriously. Our investigations into these issues have found that there are a variety of scenarios where a long running task can cause the UI thread to hang or become unresponsive. Visual Studio PerfWatson is a low overhead telemetry system that helps us capture these instances of UI unresponsiveness and report them back to Microsoft automatically and anonymously. We then use this data to drive performance improvements that make Visual Studio faster." Now instead of complaining you too can help Microsoft locate and fix performance problems with Visual Studio 2010. The requirements are: "Following are the pre-requisites for installing Visual Studio PerfWatson: Windows Vista/2008/2008 R2/7 (Note: PerfWatson is not supported for Windows XP) Visual Studio 2010 SP1 (Professional, Premium, or Ultimate)"

  • Announcing the release of the Windows Azure SDK 2.1 for .NET

    - by ScottGu
    Today we released the v2.1 update of the Windows Azure SDK for .NET.  This is a major refresh of the Windows Azure SDK and it includes some great new features and enhancements. These new capabilities include: Visual Studio 2013 Preview Support: The Windows Azure SDK now supports using the new VS 2013 Preview Visual Studio 2013 VM Image: Windows Azure now has a built-in VM image that you can use to host and develop with VS 2013 in the cloud Visual Studio Server Explorer Enhancements: Redesigned with improved filtering and auto-loading of subscription resources Virtual Machines: Start and Stop VM’s w/suspend billing directly from within Visual Studio Cloud Services: New Emulator Express option with reduced footprint and Run as Normal User support Service Bus: New high availability options, Notification Hub support, Improved VS tooling PowerShell Automation: Lots of new PowerShell commands for automating Web Sites, Cloud Services, VMs and more All of these SDK enhancements are now available to start using immediately and you can download the SDK from the Windows Azure .NET Developer Center.  Visual Studio’s Team Foundation Service (http://tfs.visualstudio.com/) has also been updated to support today’s SDK 2.1 release, and the SDK 2.1 features can now be used with it (including with automated builds + tests). Below are more details on the new features and capabilities released today: Visual Studio 2013 Preview Support Today’s Window Azure SDK 2.1 release adds support for the recent Visual Studio 2013 Preview. The 2.1 SDK also works with Visual Studio 2010 and Visual Studio 2012, and works side by side with the previous Windows Azure SDK 1.8 and 2.0 releases. To install the Windows Azure SDK 2.1 on your local computer, choose the “install the sdk” link from the Windows Azure .NET Developer Center. Then, chose which version of Visual Studio you want to use it with.  Clicking the third link will install the SDK with the latest VS 2013 Preview: If you don’t already have the Visual Studio 2013 Preview installed on your machine, this will also install Visual Studio Express 2013 Preview for Web. Visual Studio 2013 VM Image Hosted in the Cloud One of the requests we’ve heard from several customers has been to have the ability to host Visual Studio within the cloud (avoiding the need to install anything locally on your computer). With today’s SDK update we’ve added a new VM image to the Windows Azure VM Gallery that has Visual Studio Ultimate 2013 Preview, SharePoint 2013, SQL Server 2012 Express and the Windows Azure 2.1 SDK already installed on it.  This provides a really easy way to create a development environment in the cloud with the latest tools. With the recent shutdown and suspend billing feature we shipped on Windows Azure last month, you can spin up the image only when you want to do active development, and then shut down the virtual machine and not have to worry about usage charges while the virtual machine is not in use. You can create your own VS image in the cloud by using the New->Compute->Virtual Machine->From Gallery menu within the Windows Azure Management Portal, and then by selecting the “Visual Studio Ultimate 2013 Preview” template: Visual Studio Server Explorer: Improved Filtering/Management of Subscription Resources With the Windows Azure SDK 2.1 release you’ll notice significant improvements in the Visual Studio Server Explorer. The explorer has been redesigned so that all Windows Azure services are now contained under a single Windows Azure node.  From the top level node you can now manage your Windows Azure credentials, import a subscription file or filter Server Explorer to only show services from particular subscriptions or regions. Note: The Web Sites and Mobile Services nodes will appear outside the Windows Azure Node until the final release of VS 2013. If you have installed the ASP.NET and Web Tools Preview Refresh, though, the Web Sites node will appear inside the Windows Azure node even with the VS 2013 Preview. Once your subscription information is added, Windows Azure services from all your subscriptions are automatically enumerated in the Server Explorer. You no longer need to manually add services to Server Explorer individually. This provides a convenient way of viewing all of your cloud services, storage accounts, service bus namespaces, virtual machines, and web sites from one location: Subscription and Region Filtering Support Using the Windows Azure node in Server Explorer, you can also now filter your Windows Azure services in the Server Explorer by the subscription or region they are in.  If you have multiple subscriptions but need to focus your attention to just a few subscription for some period of time, this a handy way to hide the services from other subscriptions view until they become relevant. You can do the same sort of filtering by region. To enable this, just select “Filter Services” from the context menu on the Windows Azure node: Then choose the subscriptions and/or regions you want to filter by. In the below example, I’ve decided to show services from my pay-as-you-go subscription within the East US region: Visual Studio will then automatically filter the items that show up in the Server Explorer appropriately: With storage accounts and service bus namespaces, you sometimes need to work with services outside your subscription. To accommodate that scenario, those services allow you to attach an external account (from the context menu). You’ll notice that external accounts have a slightly different icon in server explorer to indicate they are from outside your subscription. Other Improvements We’ve also improved the Server Explorer by adding additional properties and actions to the service exposed. You now have access to most of the properties on a cloud service, deployment slot, role or role instance as well as the properties on storage accounts, virtual machines and web sites. Just select the object of interest in Server Explorer and view the properties in the property pane. We also now have full support for creating/deleting/update storage tables, blobs and queues from directly within Server Explorer.  Simply right-click on the appropriate storage account node and you can create them directly within Visual Studio: Virtual Machines: Start/Stop within Visual Studio Virtual Machines now have context menu actions that allow you start, shutdown, restart and delete a Virtual Machine directly within the Visual Studio Server Explorer. The shutdown action enables you to shut down the virtual machine and suspend billing when the VM is not is use, and easily restart it when you need it: This is especially useful in Dev/Test scenarios where you can start a VM – such as a SQL Server – during your development session and then shut it down / suspend billing when you are not developing (and no longer be billed for it). You can also now directly remote desktop into VMs using the “Connect using Remote Desktop” context menu command in VS Server Explorer.  Cloud Services: Emulator Express with Run as Normal User Support You can now launch Visual Studio and run your cloud services locally as a Normal User (without having to elevate to an administrator account) using a new Emulator Express option included as a preview feature with this SDK release.  Emulator Express is a version of the Windows Azure Compute Emulator that runs a restricted mode – one instance per role – and it doesn’t require administrative permissions and uses 40% less resources than the full Windows Azure Emulator. Emulator Express supports both web and worker roles. To run your application locally using the Emulator Express option, simply change the following settings in the Windows Azure project. On the shortcut menu for the Windows Azure project, choose Properties, and then choose the Web tab. Check the setting for IIS (Internet Information Services). Make sure that the option is set to IIS Express, not the full version of IIS. Emulator Express is not compatible with full IIS. On the Web tab, choose the option for Emulator Express. Service Bus: Notification Hubs With the Windows Azure SDK 2.1 release we are adding support for Windows Azure Notification Hubs as part of our official Windows Azure SDK, inside of Microsoft.ServiceBus.dll (previously the Notification Hub functionality was in a preview assembly). You are now able to create, update and delete Notification Hubs programmatically, manage your device registrations, and send push notifications to all your mobile clients across all platforms (Windows Store, Windows Phone 8, iOS, and Android). Learn more about Notification Hubs on MSDN here, or watch the Notification Hubs //BUILD/ presentation here. Service Bus: Paired Namespaces One of the new features included with today’s Windows Azure SDK 2.1 release is support for Service Bus “Paired Namespaces”.  Paired Namespaces enable you to better handle situations where a Service Bus service namespace becomes unavailable (for example: due to connectivity issues or an outage) and you are unable to send or receive messages to the namespace hosting the queue, topic, or subscription. Previously,to handle this scenario you had to manually setup separate namespaces that can act as a backup, then implement manual failover and retry logic which was sometimes tricky to get right. Service Bus now supports Paired Namespaces, which enables you to connect two namespaces together. When you activate the secondary namespace, messages are stored in the secondary queue for delivery to the primary queue at a later time. If the primary container (namespace) becomes unavailable for some reason, automatic failover enables the messages in the secondary queue. For detailed information about paired namespaces and high availability, see the new topic Asynchronous Messaging Patterns and High Availability. Service Bus: Tooling Improvements In this release, the Windows Azure Tools for Visual Studio contain several enhancements and changes to the management of Service Bus messaging entities using Visual Studio’s Server Explorer. The most noticeable change is that the Service Bus node is now integrated into the Windows Azure node, and supports integrated subscription management. Additionally, there has been a change to the code generated by the Windows Azure Worker Role with Service Bus Queue project template. This code now uses an event-driven “message pump” programming model using the QueueClient.OnMessage method. PowerShell: Tons of New Automation Commands Since my last blog post on the previous Windows Azure SDK 2.0 release, we’ve updated Windows Azure PowerShell (which is a separate download) five times. You can find the full change log here. We’ve added new cmdlets in the following areas: China instance and Windows Azure Pack support Environment Configuration VMs Cloud Services Web Sites Storage SQL Azure Service Bus China Instance and Windows Azure Pack We now support the following cmdlets for the China instance and Windows Azure Pack, respectively: China Instance: Web Sites, Service Bus, Storage, Cloud Service, VMs, Network Windows Azure Pack: Web Sites, Service Bus We will have full cmdlet support for these two Windows Azure environments in PowerShell in the near future. Virtual Machines: Stop/Start Virtual Machines Similar to the Start/Stop VM capability in VS Server Explorer, you can now stop your VM and suspend billing: If you want to keep the original behavior of keeping your stopped VM provisioned, you can pass in the -StayProvisioned switch parameter. Virtual Machines: VM endpoint ACLs We’ve added and updated a bunch of cmdlets for you to configure fine-grained network ACL on your VM endpoints. You can use the following cmdlets to create ACL config and apply them to a VM endpoint: New-AzureAclConfig Get-AzureAclConfig Set-AzureAclConfig Remove-AzureAclConfig Add-AzureEndpoint -ACL Set-AzureEndpoint –ACL The following example shows how to add an ACL rule to an existing endpoint of a VM. Other improvements for Virtual Machine management includes Added -NoWinRMEndpoint parameter to New-AzureQuickVM and Add-AzureProvisioningConfig to disable Windows Remote Management Added -DirectServerReturn parameter to Add-AzureEndpoint and Set-AzureEndpoint to enable/disable direct server return Added Set-AzureLoadBalancedEndpoint cmdlet to modify load balanced endpoints Cloud Services: Remote Desktop and Diagnostics Remote Desktop and Diagnostics are popular debugging options for Cloud Services. We’ve introduced cmdlets to help you configure these two Cloud Service extensions from Windows Azure PowerShell. Windows Azure Cloud Services Remote Desktop extension: New-AzureServiceRemoteDesktopExtensionConfig Get-AzureServiceRemoteDesktopExtension Set-AzureServiceRemoteDesktopExtension Remove-AzureServiceRemoteDesktopExtension Windows Azure Cloud Services Diagnostics extension New-AzureServiceDiagnosticsExtensionConfig Get-AzureServiceDiagnosticsExtension Set-AzureServiceDiagnosticsExtension Remove-AzureServiceDiagnosticsExtension The following example shows how to enable Remote Desktop for a Cloud Service. Web Sites: Diagnostics With our last SDK update, we introduced the Get-AzureWebsiteLog –Tail cmdlet to get the log streaming of your Web Sites. Recently, we’ve also added cmdlets to configure Web Site application diagnostics: Enable-AzureWebsiteApplicationDiagnostic Disable-AzureWebsiteApplicationDiagnostic The following 2 examples show how to enable application diagnostics to the file system and a Windows Azure Storage Table: SQL Database Previously, you had to know the SQL Database server admin username and password if you want to manage the database in that SQL Database server. Recently, we’ve made the experience much easier by not requiring the admin credential if the database server is in your subscription. So you can simply specify the -ServerName parameter to tell Windows Azure PowerShell which server you want to use for the following cmdlets. Get-AzureSqlDatabase New-AzureSqlDatabase Remove-AzureSqlDatabase Set-AzureSqlDatabase We’ve also added a -AllowAllAzureServices parameter to New-AzureSqlDatabaseServerFirewallRule so that you can easily add a firewall rule to whitelist all Windows Azure IP addresses. Besides the above experience improvements, we’ve also added cmdlets get the database server quota and set the database service objective. Check out the following cmdlets for details. Get-AzureSqlDatabaseServerQuota Get-AzureSqlDatabaseServiceObjective Set-AzureSqlDatabase –ServiceObjective Storage and Service Bus Other new cmdlets include Storage: CRUD cmdlets for Azure Tables and Queues Service Bus: Cmdlets for managing authorization rules on your Service Bus Namespace, Queue, Topic, Relay and NotificationHub Summary Today’s release includes a bunch of great features that enable you to build even better cloud solutions.  All the above features/enhancements are shipped and available to use immediately as part of the 2.1 release of the Windows Azure SDK for .NET. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • VB.NET IF() Coalesce and “Expression Expected” Error

    - by Jeff Widmer
    I am trying to use the equivalent of the C# “??” operator in some VB.NET code that I am working in. This StackOverflow article for “Is there a VB.NET equivalent for C#'s ?? operator?” explains the VB.NET IF() statement syntax which is exactly what I am looking for... and I thought I was going to be done pretty quickly and could move on. But after implementing the IF() statement in my code I started to receive this error: Compiler Error Message: BC30201: Expression expected. And no matter how I tried using the “IF()” statement, whenever I tried to visit the aspx page that I was working on I received the same error. This other StackOverflow article Using VB.NET If vs. IIf in binding/rendering expression indicated that the VB.NET IF() operator was not available until VS2008 or .NET Framework 3.5.  So I checked the Web Application project properties but it was targeting the .NET Framework 3.5: So I was still not understanding what was going on, but then I noticed the version information in the detailed compiler output of the error page: This happened to be a C# project, but with an ASPX page with inline VB.NET code (yes, it is strange to have that but that is the project I am working on).  So even though the project file was targeting the .NET Framework 3.5, the ASPX page was being compiled using the .NET Framework 2.0.  But why?  Where does this get set?  How does ASP.NET know which version of the compiler to use for the inline code? For this I turned to the web.config.  Here is the system.codedom/compilers section that was in the web.config for this project: <system.codedom>     <compilers>         <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">             <providerOption name="CompilerVersion" value="v3.5" />             <providerOption name="WarnAsError" value="false" />         </compiler>     </compilers> </system.codedom> Keep in mind that this is a C# web application project file but my aspx file has inline VB.NET code.  The web.config does not have any information for how to compile for VB.NET so it defaults to .NET 2.0 (instead of 3.5 which is what I need). So the web.config needed to include the VB.NET compiler option.  Here it is with both the C# and VB.NET options (I copied the VB.NET config from a new VB.NET Web Application project file).     <system.codedom>         <compilers>             <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">                 <providerOption name="CompilerVersion" value="v3.5" />                 <providerOption name="WarnAsError" value="false" />             </compiler>       <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">         <providerOption name="CompilerVersion" value="v3.5"/>         <providerOption name="OptionInfer" value="true"/>         <providerOption name="WarnAsError" value="false"/>       </compiler>     </compilers>     </system.codedom>   So the inline VB.NET code on my aspx page was being compiled using the .NET Framework 2.0 when it really needed to be compiled with the .NET Framework 3.5 compiler in order to take advantage of the VB.NET IF() coalesce statement.  Without the VB.NET web.config compiler option, the default is to compile using the .NET Framework 2.0 and the VB.NET IF() coalesce statement does not exist (at least in the form that I want it in).  FYI, there is an older IF statement in VB.NET 2.0 compiler which is why it is giving me the unusual “Expression Expected” error message – see this article for when VB.NET got the new updated version. EDIT (2011-06-20): I had made a wrong assumption in the first version of this blog post.  After a little more research and investigation I was able to figure out that the issue was in the web.config and not with the IIS App Pool.  Thanks to the comment from James which forced me to look into this again.

  • AutoVue Integrates with Primavera P6

    - by celine.beck
    Oracle's Primavera P6 Enterprise Project Portfolio Management is an integrated project portfolio management (PPM) application that helps select the right strategic mix of projects, balance resource capacity, manage project risk and complete projects on time and within budget. AutoVue 19.3 and later versions (release 20.0) now integrate out of the box with the Web version of Oracle Primavera P6 release 7. The integration between the two products, which was announced during Oracle Open World 2009, provides project teams with ready access to any project documents directly from within the context of P6 in support for project scope definition and project planning and execution. You can learn more about the integration between AutoVue and Primavera P6 by: Listening to the Oracle Appcast entitled Enhance Primavera Project Document Collaboration with AutoVue Enterprise Visualization Watching an Oracle Webcast about how to improve project success with document visualization and collaboration Watching a recorded demo of the integrated solution Teams involved in complex projects like construction or plant shutdown activities are highly interdependent: the decisions of one affecting the actions of many others. This coupled with increasing project complexity, a vast array of players and heavy engineering and document-intensive workflows makes it more challenging to complete jobs on time and within budget. Organizations need complete visibility into project information, as well as robust project planning, risk analysis and resource balancing capabilities similar to those featured in Primavera P6 ; they also need to make sure that all project stakeholders, even those who neither understand engineering drawings nor are interested in engineering details that go beyond their specific needs, have ready access to technically advanced project information. This is exactly what the integration between AutoVue and Primavera delivers: ready access to any project information attached to Primavera projects, tasks or activities via AutoVue. There is no need for users to waste time searching for project-related documents or disrupting engineers for printouts, users have all the context they need to make sound decisions right from within Primavera P6 with a single click of a button. We are very excited about this new integration. If you are using Primavera and / or Primavera tied with AutoVue, we would be interested in getting your feedback on this integration! Please do not hesitate to post your comments / reactions on the blog!

  • A Nondeterministic Engine written in VB.NET 2010

    - by neil chen
    When I'm reading SICP (Structure and Interpretation of Computer Programs) recently, I'm very interested in the concept of an "Nondeterministic Algorithm". According to wikipedia:  In computer science, a nondeterministic algorithm is an algorithm with one or more choice points where multiple different continuations are possible, without any specification of which one will be taken. For example, here is an puzzle came from the SICP: Baker, Cooper, Fletcher, Miller, and Smith live on different floors of an apartment housethat contains only five floors. Baker does not live on the top floor. Cooper does not live onthe bottom floor. Fletcher does not live on either the top or the bottom floor. Miller lives ona higher floor than does Cooper. Smith does not live on a floor adjacent to Fletcher's.Fletcher does not live on a floor adjacent to Cooper's. Where does everyone live? After reading this I decided to build a simple nondeterministic calculation engine with .NET. The rough idea is that we can use an iterator to track each set of possible values of the parameters, and then we implement some logic inside the engine to automate the statemachine, so that we can try one combination of the values, then test it, and then move to the next. We also used a backtracking algorithm to go back when we are running out of choices at some point. Following is the core code of the engine itself: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--Public Class NonDeterministicEngine Private _paramDict As New List(Of Tuple(Of String, IEnumerator)) 'Private _predicateDict As New List(Of Tuple(Of Func(Of Object, Boolean), IEnumerable(Of String))) Private _predicateDict As New List(Of Tuple(Of Object, IList(Of String))) Public Sub AddParam(ByVal name As String, ByVal values As IEnumerable) _paramDict.Add(New Tuple(Of String, IEnumerator)(name, values.GetEnumerator())) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(1, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(2, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(3, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(4, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(5, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(6, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Object, Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(7, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Public Sub AddRequire(ByVal predicate As Func(Of Object, Object, Object, Object, Object, Object, Object, Object, Boolean), ByVal paramNames As IList(Of String)) CheckParamCount(8, paramNames) _predicateDict.Add(New Tuple(Of Object, IList(Of String))(predicate, paramNames)) End Sub Sub CheckParamCount(ByVal count As Integer, ByVal paramNames As IList(Of String)) If paramNames.Count <> count Then Throw New Exception("Parameter count does not match.")

  • Transactions in LINQ to SQL applications

    - by nikolaosk
    In this post I would like to talk about LINQ to SQL and transactions.When I have a LINQ to SQL class I always get asked this question, "How does LINQ treat Transactions?". When we use the DeleteOnSubmit() method or the InsertOnSubmit() method, all of those commands at some point are translated into T-SQL commands and then are executed against the database. All of those commands live in transactions and they follow the basic rules of transaction processing. They do succeed together or fail together...(read more)

  • An abundance of LINQ queries and expressions using both the query and method syntax.

    - by nikolaosk
    In this post I will be writing LINQ queries against an array of strings, an array of integers.Moreover I will be using LINQ to query an SQL Server database. I can use LINQ against arrays since the array of strings/integers implement the IENumerable interface. I thought it would be a good idea to use both the method syntax and the query syntax. There are other places on the net where you can find examples of LINQ queries but I decided to create a big post using as many LINQ examples as possible. We...(read more)

  • AutoVue at the Oracle Asset Lifecycle Management Summit

    - by celine.beck
    I recently had the opportunity to attend and present the integration between AutoVue and Primavera P6 during the Oracle ALM Summit, which was held in March at Redwood Shores, on Oracle Headquarters grounds. The ALM Summit brought together over 300 Oracle maintenance practitioners who endured the foggy and rainy San Francisco weather to attend the 4th edition of this Oracle-driven conference. Attendees have roles in maintenance management and IT. Following a general session, Ralph Rio from ARC Advisory Group provided a very interesting keynote session discussing Asset Management directions, both in the short and long run. An interesting point that Ralph raised is that most organizations have done a good job at improving performance at the design / build, operate and maintain and portfolio management phases by leveraging solutions like Asset Lifecycle Management and Project & Portfolio management solutions; however, there seem to be room for improvement in between those phases, when information flows from one group to the other, during the data handover phase or when time comes to update / modify drawings to reflect the reality of physical assets. This is where AutoVue comes into play. By integrating with enterprise applications like content management systems, asset lifecycle management applications and project management solutions, AutoVue can be a real-process enabler, streamlining information flows from concept/design to decommissioning and ensuring that all project stakeholders have access to asset information and engineering data throughout the asset lifecycle. AutoVue's built-in digital annotation capabilities allows maintenance workers and technicians to report changes in configuration and visually capture the delta between as-built and as-maintained versions of asset documents. This information can then be easily handed over to engineers who can identify changes and incorporate these modifications into the drawings during the next round of document revisions. PPL Power Generation, an electric utilities headquarted in Allentown, Pennsylvania discussed this usage of AutoVue during an interesting Webcast around AutoVue's role in the Utilities space. After the keynote sessions, participants broke off into product-centric tracks around Oracle's Asset Lifecycle Management solutions (E-Business Suite, PeopleSoft, and JD Edwards). The second day of the conference was the occasion for us to present the integration between AutoVue and Primavera P6 to the Maintenance Summit audience. The presentation was a great success and generated much discussion with partners and customers during breaks. People seemed highly interested in learning more about our plans for integrating AutoVue and Primavera P6 with Oracle's ALM solutions...stay tune for further information on the subject!

  • Cooking with Wessty: HTML 5 and Visual Studio

    - by David Wesst
    The hardest part about using a new technology, such as HTML 5, is getting to what features are available and the syntax. One way to learn how to use new technologies is to adapt your current development to help you use the technology in comfort of your own development environment. For .NET Web Developers, that environment is usually Visual Studio 2010. This technique intends on showing you how to get HTML 5 Intellisense working in your current version of Visual Studio 2008 or 2010, making it easier for you to start using HTML 5 features in your current .NET web development projects. Quick Note According to the Visual Web Developer team at Microsoft, the Visual Studio 2010 SP1 beta has support for both HTML 5 and CSS 3. If you are willing to try out the bleeding edge update from Microsoft, then you won’t need this technique. --- Ingredients Visual Studio 2008 or 2010 Your favourite HTML 5 compliant browser (e.g. Internet Explorer 9) Administrator privileges, or the ability to install Visual Studio Extensions in your development environment. Directions Download the HTML 5 Intellisense for Visual Studio 2008 and 2010 extension from the Visual Studio Extension Gallery. Install it. Open Visual Studio. Open up a web file, such as an HTML or ASPX file. he HTML Source Editing toolbar should have appeared. (Optional) If it did not appear, you can activate it through the main menu by selecting View, then Toolbars, and then select HTML Source Editing if it does not have a checkbox beside it. (NOTE: If there is a checkbox, then the toolbar is enabled) In the HTML Source Editing toolbar, open up the validation schema drop box, and select HTML 5. Et voila! You now have HTML 5 intellisense enabled to help you get started in adding HTML 5 awesomeness to your web sites and web applications. Optional – Setting HTML 5 Validation Options At this point, you may want to select how Visual Studio shows validation errors. You can do that in the Options Menu. To get to the Options Menu… In the main menu select Tools, then Options. In the Options window, select and expand Text Editor, then HTML, followed by selecting Validation.

  • Updating a Progress Bar within the Status Bar [migrated]

    - by Muhnamana
    I'm trying to figure out how to incorporate a progress bar within the status bar to show how much processing is completed. Below is my example of updating the progress bar (not sure if this is the correct way or not) Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick ToolStripProgressBar1.Value = ToolStripProgressBar1.Value + 2 If ToolStripProgressBar1.Value = 100 Then ToolStripProgressBar1.Value = 0 ToolStripProgressBar1.Value = ToolStripProgressBar1.Value + 2 Timer1.Enabled = True End If End Sub Here is the code within the button. Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1Run.Click ToolStripStatusLabel1.Text = "Processing..." Timer1.Enabled = True 'more code to be inserted here End Sub What I'm not sure is how to update the progress bar based on the amount of code you have and once the processing is complete, update the ToolStripStatusLabel1 to show "Processing...Complete!".

This was almost entirely due to a couple of MVPs criticizing me for raising awareness of certain Connect items instead of letting them be found "naturally." I wasn't sure what world they were living in, where droves of everyday end users just happened to stumble upon Connect items without any prompting. I suppose it could be said that the...(read more)

    I have a code of a Plug In from an SDK. The code is in Debug Mode. I use Intel Compiler which only applies optimizations in Release Mode. Under configuration manager of the project only "Debug" mode is defined. How could I switch to "Release" mode and enable all Intel Compiler's optimizations? If I enable them on debug mode nothing is applied (Empty Report). I couldn't find the trick to do so. Thank You.
