  • Installing Visual Studio 2010 SP1 or Windows Phone tools in your VM (danger!)

    - by Jeff
    If you've read my blog for any amount of time, you probably know that I tend to develop stuff in a Parallels VM on a Mac. It's how I roll. I like VM's because I can trash them and do really stupid things with beta software. That said, there is a pain point that doesn't seem that well documented when it comes to installing stuff in this scenario.The WP7 tools, and SP1 for Visual Studio 2010 (perhaps only if you already have the WP7 tools installed, I'm not sure), do something strange on install. As if it weren't already a long and slow installation, for reasons I don't understand, the installer fires up an instance of Windows Phone Emulator. As you may already know, the emulator doesn't run in a VM, because it is itself a VM, apparently. What it will do is fire up your CPU, make your comprooder hot and make the fans blow harder.I found this out accidentally, as I started the (slow) phone tool installation once, and walked away. An hour and a half later, I came back to find it hadn't finished. But it was hot and the CPU was pegged, so I fired up the task manager to find XDE.exe, the phone emulator, cranking away. I had to kill it several times, and eventually the install finished. It fired up just once in the SP1 install, but it still had the same hanging effect.I can't for the life of me figure out why it does this. In a VM, I can connect the phone to it and use that, so I don't need the emulator. But this install, firing up the emulator, will make it choke until you kill the XDE.exe process. Watch out!

  • Gave a talk at SoCal Code Camp at USC today titled “Linq to Objects A-Z”

    - by dotneteer
    I gave a talk at SoCal Code Camp on Linq to Objects. With careful categorization of Linq functions, I was able to cover the entire set of Linq functions in only 35 minutes. I was able to spend the rest time on demos. In my first demo, I show I was able to write a top 20 URL type of query using 4 lines of library code and 9 line of Linq code without tools like Log Parser. I also demonstrated that I only need to change 2 lines of code from querying a single log file to a whole directory of log files. It would be as simple to run the query against multiple servers in parallel. In my second demo, I discussed how to turn into graph depth-first-search (DFS) and breath-first-search (BFS) in the a Linq queryable problem. The class LingToGraph contains the only DFS and BFS code I ever have to write; the rest could be done the the lambda passed to the DFS or BFS calls. In future blogs, I will provide more details explanation of code. Links: Link to Powerpoint slides. Link to demos.

  • How can I lower my C# learning curve? [closed]

    - by MSU
    I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

  • Upgrading a hard disk – To repave or to migrate, that is the question

    - by guybarrette
    I recently changed my laptop hard disk from the stock 250GB 5400 drive to a 320GB 7200 drive.  And no, I didn’t bought a SSD drive because the cost is way too much right now.  At $70, my upgrade was a lot cheaper than a SSD drive.  Maybe next year. When changing a system main hard drive, one must ask himself: To repave or to migrate, that is the question.  I choose to migrate so I went to the Acronis Website to take a look at their product line.  They have a few products that could do the job.  One being Acronis Migrate Easy 7.0 and the other being Acronis True Image Home 2010.  Since True Image was just $10 more then Migrate Easy, I bought True Image. I inserted my new hard drive in a 2.5” USB enclosure, and started the migration process.  Once the data copied, I switched the drives.  The process went very smoothly and without hiccups.  Highly recommended. BTW, Acronis offers free trials so I guess that nothing can stop you from “testing” a migration  ;-) var addthis_pub="guybarrette";

  • Extension methods on a null object instance – something you did not know

    - by nmarun
    Extension methods gave developers with a lot of bandwidth to do interesting (read ‘cool’) things. But there are a couple of things that we need to be aware of while using these extension methods. I have a StringUtil class that defines two extension methods: 1: public static class StringUtils 2: { 3: public static string Left( this string arg, int leftCharCount) 4: { 5: if (arg == null ) 6: { 7: throw new ArgumentNullException( "arg" ); 8: } 9: return arg.Substring(0, leftCharCount); 10...(read more)

  • Which license can I use for my open source AWS project [closed]

    - by mafue
    I'm creating a project on codeplex that uses Amazon Web Services and the AWS SDK for .NET Which licenses can I use? The SDK is released under Apache 2.0 license, so I assume my project can or should use the same. If I add another open source library released under a different license, do I need to find a license that is 'compatible' with both ie. one that has the same requirements for derivative works? My requirement is for a license that allows me to publish a derivative work from the AWS .NET SDK. I can use any of the licenses that codeplex supports, which includes: Apache 2.0 GNU GPLv2 MIT Mozilla Public License 2.0 Microsoft Public License

  • Anyone know about AppDynamics? Does Microsoft already have something similiar? Event viewer? Im confused

    - by punkouter
    We have a big collection of java (80%) and .Net (20%) apps.. And the people in charge want a way to monitor the applications somehow. So they told me they are interested in AppDynamics? I have spent a bit looking into it but I still don't get it. Can someone tell me what its about ? From my understanding it seems like you would someone inject the AppDynamics API in your code to tell about differnt events that occur? So sounds like Event Viewer ? I am on the .NET side of this and seems to me we can just write data to a log and report off of that data.. I don't get what the additional complexity of using'AppDynamics' does. Maybe it is overkill ??

  • Windows 7 – Fun with VHD

    - by guybarrette
    I’m teaching about TFS 2008 next week and I wanted to use TFS in a virtualized environment so I downloaded the TFS + Team Suite VPC image from Microsoft’s Website.  Working with Windows 7, I opened the VM with the built-in Windows Virtual PC.  The VM loads fine but the problems started when I tried to install the VM additions: I simply couldn’t get them to install properly. I then looked at VMware and found that they have a product called VMware Player that can load Virtual PC VMs.  Tried that but VMware Player failed in converting the VHD. I then looked at VirtualBox.  Created a new VM, attached the VHD and bingo!  Worked like a charm.  The only real caveat is that the guest Windows will ask for the OS CDs to install new drivers so you must have either the CD/DVD or the ISO file (sweet!) to proceed. OK, I got it working in VirtualBox but I’m curious why I couldn’t install the additions from Windows 7 Virtual PC onto a Windows Server 2003 VM.  Anyone has a clue? BTW, thanks to Rolly Perreaux who pointed my to his blog where he goes into great details explaining how to use VM images with VirtualBox.  Good stuff! var addthis_pub="guybarrette";

  • Analytics for Windows 8 apps using Markedup

    - by nmarun
    The Windows 8 store does provide some analytics information to you in terms of downloads by market or by age group, ratings, in-app purchases. I find that a little too limiting. What if I want to know what page my users are spending most of their time or what events are being raised more frequently or are my users calling my app through the search contract I implemented or how many times was the share contract called. To answer questions like this, you need a more mature analytics framework. Markedup...(read more)

  • Flattening System.Web.UI ControlCollection

    - by evovision
    Hi,   Sometimes one may need to get a list of child controls inside specific container and don't care about the underlying hierarchy.   The result is beautifully achieved using this extension method:   using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;    public static class ControlCollectionExtensionMethods    {        public static IEnumerable<Control> FlattenedList(this ControlCollection controls)        {            foreach (Control ctrl in controls)            {                  // return parent control                   yield return ctrl;                              // and dive into child collection                   foreach (Control child in ctrl.Controls.FlattenedList())                         yield return child;            }        }    }   P.S.: don't forget about namespaces when using it in your code, if above class is wrapped into namespace, for example: Sample, the source code file with calling code must explicitly reference it: using Sample;

  • Multitenancy in SQL Azure

    - by cibrax
    If you are building a SaaS application in Windows Azure that relies on SQL Azure, it’s probably that you will need to support multiple tenants at database level. This is short overview of the different approaches you can use for support that scenario, A different database per tenant A new database is created and assigned when a tenant is provisioned. Pros Complete isolation between tenants. All the data for a tenant lives in a database only he can access. Cons It’s not cost effective. SQL Azure databases are not cheap, and the minimum size for a database is 1GB.  You might be paying for storage that you don’t really use. A different connection pool is required per database. Updates must be replicated across all the databases You need multiple backup strategies across all the databases Multiple schemas in a database shared by all the tenants A single database is shared among all the tenants, but every tenant is assigned to a different schema and database user. Pros You only pay for a single database. Data is isolated at database level. If the credentials for one tenant is compromised, the rest of the data for the other tenants is not. Cons You need to replicate all the database objects in every schema, so the number of objects can increase indefinitely. Updates must be replicated across all the schemas. The connection pool for the database must maintain a different connection per tenant (or set of credentials) A different user is required per tenant, which is stored at server level. You have to backup that user independently. Centralizing the database access with store procedures in a database shared by all the tenants A single database is shared among all the tenants, but nobody can read the data directly from the tables. All the data operations are performed through store procedures that centralize the access to the tenant data. The store procedures contain some logic to map the database user to an specific tenant. Pros You only pay for a single database. You only have a set of objects to maintain and backup. Cons There is no real isolation. All the data for the different tenants is shared in the same tables. You can not use traditional ORM like EF code first for consuming the data. A different user is required per tenant, which is stored at server level. You have to backup that user independently. SQL Federations A single database is shared among all the tenants, but a different federation is used per tenant. A federation in few words, it’s a mechanism for horizontal scaling in SQL Azure, which basically uses the idea of logical partitions to distribute data based on certain criteria. Pros You only have a single database with multiple federations. You can use filtering in the connections to pick the right federation, so any ORM could be used to consume the data. Cons There is no real isolation at that database level. The isolation is enforced programmatically with federations.

  • Hash Function Added To The PredicateEqualityComparer

    - by Paulo Morgado
    Sometime ago I wrote a predicate equality comparer to be used with LINQ’s Distinct operator. The Distinct operator uses an instance of an internal Set class to maintain the collection of distinct elements in the source collection which in turn checks the hash code of each element (by calling the GetHashCode method of the equality comparer) and only if there’s already an element with the same hash code in the collection calls the Equals method of the comparer to disambiguate. At the time I provided only the possibility to specify the comparison predicate, but, in some cases, comparing a hash code instead of calling the provided comparer predicate can be a significant performance improvement, I’ve added the possibility to had a hash function to the predicate equality comparer. You can get the updated code from the PauloMorgado.Linq project on CodePlex,

  • Editing assemblies using ReflexIL

    - by nmarun
    I have known ReflexIL for quite some time, so I thought I’ll write a line or two about this simple and yet power tool. This tool runs as a plug-in for Red Gate’s Reflector . I’m not sure if I can cover all the features of this tool, but there are a couple that I really liked that we’ll just see those. In order to get it working, you unzip the contents of the file to some folder. In Reflector, under Tools->Add-Ins add the path to the Reflexil.Reflector.dll. And, you’re set.

  • Using Unity – Part 5

    - by nmarun
    In the previous article of the series, I talked about constructor and property (setter) injection. I wanted to write about how to work with arrays and generics in Unity in this blog, after seeing how lengthy this one got, I’ve decided to write about generics in the next one. This one will only concentrate on arrays. My Product4 class has the following definition: 1: public interface IProduct 2: { 3: string WriteProductDetails(); 4: } 5:  6: public class Product4 : IProduct 7: { 8: public string Name { get; set; } 9: public ILogger[] Loggers { get; set; } 10:  11: public Product4(string productName, ILogger[] loggers) 12: { 13: Name = productName; 14: Loggers = loggers; 15: } 16:  17: public string WriteProductDetails() 18: { 19: StringBuilder productDetails = new StringBuilder(); 20: productDetails.AppendFormat("{0}<br/>", Name); 21: for (int i = 0; i < Loggers.Count(); i++) 22: { 23: productDetails.AppendFormat("{0}<br/>", Loggers[i].WriteLog()); 24: } 25: 26: return productDetails.ToString(); 27: } 28: } The key parts are line 4 where we declare an array of ILogger and line 5 where-in the constructor passes an instance of an array of ILogger objects. I’ve created another class – FakeLogger: 1: public class FakeLogger : ILogger 2: { 3: public string WriteLog() 4: { 5: return string.Format("Type: {0}", GetType()); 6: } 7: } It’s implementation is the same as what we had for the FileLogger class. Coming to the web.config file, first add the following aliases. The alias for FakeLogger should make sense right away. ILoggerArray defines an array of ILogger objects. I’ll tell why we need an alias for System.String data type. 1: <typeAlias alias="string" type="System.String, mscorlib" /> 2: <typeAlias alias="ILoggerArray" type="ProductModel.ILogger[], ProductModel" /> 3: <typeAlias alias="FakeLogger" type="ProductModel.FakeLogger, ProductModel"/> Next is to create mappings for the FileLogger and FakeLogger classes: 1: <type type="ILogger" mapTo="FileLogger" name="logger1"> 2: <lifetime type="singleton" /> 3: </type> 4: <type type="ILogger" mapTo="FakeLogger" name="logger2"> 5: <lifetime type="singleton" /> 6: </type> Finally, for the real deal: 1: <type type="IProduct" mapTo="Product4" name="ArrayProduct"> 2: <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement,Microsoft.Practices.Unity.Configuration, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"> 3: <constructor> 4: <param name="productName" parameterType="string" > 5: <value value="Product name from config file" type="string"/> 6: </param> 7: <param name="loggers" parameterType="ILoggerArray"> 8: <array> 9: <dependency name="logger2" /> 10: <dependency name="logger1" /> 11: </array> 12: </param> 13: </constructor> 14: </typeConfig> 15: </type> Here’s where I’m saying, that if a type of IProduct is requested to be resolved, map it to type Product4. Furthermore, the Product4 has two constructor parameters – a string and an array of type ILogger. You might have observed the first parameter of the constructor is named ‘productName’ and that matches the value in the name attribute of the param element. The parameterType of ‘string’ maps to ‘System.String, mscorlib’ and is defined in the type alias above. The set up is similar for the second constructor parameter. The name matches the name of the parameter (loggers) and is of type ILoggerArray, which maps to an array of ILogger objects. We’ve also decided to add two elements to this array when unity resolves it – an instance of FileLogger and one of FakeLogger. The click event of the button does the following: 1: //unityContainer.RegisterType<IProduct, Product4>(); 2: //IProduct product4 = unityContainer.Resolve<IProduct>(); 3: IProduct product4 = unityContainer.Resolve<IProduct>("ArrayConstructor"); 4: productDetailsLabel.Text = product4.WriteProductDetails(); It’s worth mentioning here about the change in the format of resolving the IProduct to create an instance of Product4. You cannot use the regular way (the commented lines) to get an instance of Product4. The reason is due to the behavior of Unity which Alex Ermakov has brilliantly explained here. The corresponding output of the action is: You have a couple of options when it comes to adding dependency elements in the array node. You can: - leave it empty (no dependency elements declared): This will only create an empty array of loggers. This way you can check for non-null condition, in your mock classes. - add multiple dependency elements with the same name 1: <param name="loggers" parameterType="ILoggerArray"> 2: <array> 3: <dependency name="logger2" /> 4: <dependency name="logger2" /> 5: </array> 6: </param> With this you’ll see two instances of FakeLogger in the output. This article shows how Unity allows you to instantiate objects with arrays. Find the code here.

  • Converting a Visual Studio 2003 Web Project to a Visual Studio 2008 Web Application Project

    - by navaneeth
    This walkthrough describes how to convert a Visual Studio .NET 2002 or Visual Studio .NET 2003 Web project to a Visual Studio 2008 Web application project. The Visual Studio 2008 Web application project model is like the Visual Studio 2005 Web application project model. Therefore, the conversion processes are similar. For more information about Web application projects, see ASP.NET Web Application Projects. You can also convert from a Visual Studio .NET Web project to a Visual Studio 2008 Web site project. However, conversion to a Web application project is the approach that is supported, and gives you the convenience of tools to help with the conversion. For example, when you convert to a Visual Studio 2008 Web application project, you can use the Visual Studio Conversion Wizard to automate part of the process. For information about how to convert a Visual Studio .NET Web project to a Visual Studio 2008 Web site, see Common Web Project Conversion Issues and Solutions. There are two parts involved in converting a Visual Studio 2002 or 2003 Web project to a Visual Studio 2008 Web application project. The parts are as follows: Converting the project. You can use the Visual Studio Conversion Wizard for the initial conversion of the project and Web.config files. You can later use the Convert To Web Application command to update the project's files and structure. Upgrading the .NET Framework version of the project. You must upgrade the project's .NET Framework version to either .NET Framework 2.0 SP1 or to .NET Framework 3.5. This .NET Framework version upgrade is required because Visual Studio 2008 cannot target earlier versions of the .NET Framework. You can perform this upgrade during the project conversion, by using the Conversion Wizard. Alternatively, you can upgrade the .NET Framework version after you convert the project.   NoteYou can change a project's .NET Framework version manually. To do so, in Visual Studio open the property pages for the project, click the Application tab, and then select a new version from the Target Framework list. This walkthrough illustrates the following tasks: Opening the Visual Studio .NET project in Visual Studio 2008 and creating a backup of the project files. Upgrading the .NET Framework version that the project targets. Converting the project file and the Web.config file. Converting ASP.NET code files. Testing the converted project. Prerequisites    To complete this walkthrough, you will need: Visual Studio 2008. A Web site project that was created in Visual Studio .NET version 2002 or 2003 that compiles and runs without errors. Converting the Project and Upgrading the .NET Framework Version    To begin, you open the project in Visual Studio 2008, which starts the conversion. It offers you an opportunity to back up the project before converting it. NoteIt is strongly recommended that you back up the project. The conversion works on the original project files, which cannot be recovered if the conversion is not successful.To convert the project and back up the files In Visual Studio 2008, in the File menu, click Open and then click Project. The Open Project dialog box is displayed. Browse to the folder that contains the project or solution file for the Visual Studio .NET project, select the file, and then click Open. NoteMake sure that you open the project by using the Open Project command. If you use the Open Web Site command, the project will be converted to the Web site project format.The Conversion Wizard opens and prompts you to create a backup before converting the project. To create the backup, click Yes. Click Browse, select the folder in which the backup should be created, and then click Next. Click Finish. The backup starts. NoteThere might be significant delays as the Conversion Wizard copies files, with no updates or progress indicated. Wait until the process finishes before you continue.When the conversion finishes, the wizard prompts you to upgrade the targeted version of the .NET Framework for the project. To upgrade to the .NET Framework 3.5, click Yes. To upgrade the project to target the .NET Framework 2.0 SP1, click No. It is recommended that you leave the check box selected that asks whether you want to upgrade all Webs in the solution. If you upgrade to .NET Framework 3.5, the project's Web.config file is modified at the same time as the project file. When the upgrade and conversion have finished, a message is displayed that indicates that you have completed the first step in converting your project. Click OK. The wizard displays status information about the conversion. Click Close. Testing the Converted Project    After the conversion has finished, you can test the project to make sure that it runs. This will also help you identify code in the project that must be updated. To verify that the project runs If you know about changes that are required for the code to run with the new version of the .NET Framework, make those changes. In the Build menu, click Build. Any missing references or other compilation issues in the project are displayed in the Error List window. The most likely issues are missing assembly references or issues with dynamically generated types. In Solution Explorer, right-click the Web page that will be used to launch the application, and then click Set as Start Page. On the Debug menu, click Start Debugging. If debugging is not enabled, the Debugging Not Enabled dialog box is displayed. Select the option to add a Web.config file that has debugging enabled, and then click OK. Verify that the converted project runs as expected. Do not continue with the conversion process until all build and run-time errors are resolved. Converting ASP.NET Code Files    ASP.NET Web page files and user-control files in Visual Studio 2008 that use the code-behind model have an associated designer file. The files that you just converted will have an associated code-behind file, but no designer file. Therefore, the next step is to generate designer files. NoteOnly ASP.NET Web pages and user controls that have their code in a separate code file require a separate designer file. For pages that have inline code and no associated code file, no designer file will be generated.To convert ASP.NET code files In Solution Explorer, right-click the project node, and then click Convert To Web Application. The files are converted. Verify that the converted code files have a code file and a designer file. Build and run the project to verify the results of the conversion.

    I was creating another usercontrol with Telerik's RadGrid and Calendar. <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> <table class="style1"> <tr> <td>From</td> <td>To</td> </tr> <tr> <td><asp:Calendar ID="Calendar1" runat="server" SelectionMode="Day"></asp:Calendar></td> <td><asp:Calendar ID="Calendar2" runat="server" SelectionMode="Day"></asp:Calendar></td> </tr> <tr> <td><asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /></td> <td><asp:Button ID="btnClear" runat="server" Text="Clear" OnClick="btnClear_Click" /></td> </tr> </table> <telerik:RadGrid ID="RadGrid1" runat="server"> <MasterTableView CommandItemDisplay="Top"></MasterTableView> </telerik:RadGrid> and I am using Linq in code-behind: Entities1 entities = new Entities1(); public static object DataSource = null; protected void Page_Load(object sender, EventArgs e) { if (DataSource == null) { DataSource = (from entity in entities.nsc_moneytransaction select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }).OrderByDescending(a => a.date); } BindData(); } public void BindData() { RadGrid1.DataSource = DataSource; } protected void btnSubmit_Click(object sender, EventArgs e) { DateTime startdate = new DateTime(); DateTime enddatedate = new DateTime(); if (Calendar1.SelectedDate != null && Calendar2.SelectedDate != null) { startdate = Calendar1.SelectedDate; enddatedate = Calendar2.SelectedDate; var queryDateRange = from entity in entities.nsc_moneytransaction where DateTime.Parse(entity.transaction_date.Value.ToShortDateString()) >= DateTime.Parse(startdate.ToShortDateString()) && DateTime.Parse(entity.transaction_date.Value.ToShortDateString()) <= DateTime.Parse(enddatedate.ToShortDateString()) select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }; DataSource = queryDateRange.OrderByDescending(a => a.date); } else if (Calendar1.SelectedDate != null) { startdate = Calendar1.SelectedDate; var querySetDate = from entity in entities.nsc_moneytransaction where entity.transaction_date.Value == startdate select new { date = entity.transaction_date.Value, username = entity.username, cashbalance = entity.cash_balance }; DataSource = querySetDate.OrderByDescending(a => a.date); ; } BindData(); } protected void btnClear_Click(object sender, EventArgs e) { Calendar1.SelectedDates.Clear(); Calendar2.SelectedDates.Clear(); } The problems are, (1) when I click the submit button. the data in the RadGrid is not changed. (2) how can we check if there is nothing selected in the Calendar controls, because there is a date (01/01/0001) set even if we do not select anything from that calendar, thus Calendar1.SelectedDate != null is not enough. =( Thanks.
