  • Running ASP / ASP.NET markup outside of a web application (perhaps with MVC)

    - by Frank Schwieterman
    Is there a way to include some aspx/ascx markup in a DLL and use that to generate text dynamically? I really just want to pass a model instance to a view and get the produced html as a string. Similar to what you might do with an XSLT transform, except the transform input is a CLR object rather than an XML document. A second benefit is using the ASP.NET code-behind markup which is known by most team members. One way to achieve this would be to load the MVC view engine in-process and perhaps have it use an ASPX file from a resource. It seems like I could call into just the ViewEngine somehow and have it generate a ViewEngineResult. I don't know ASP.NET MVC well enough though to know what calls to make. I don't think this would be possible with classic ASP or ASP.NET as the control model is so tied to the page model, which doesn't exist in this case. Using something like SparkViewEngine in isolation would be cool too, though not as useful since other team members wouldn't know the syntax. At that point I might as well use XSLT (yes I am looking for a clever way to avoid XSLT).

  • Is their a definitive list for the differences between the current version of SQL Azure and SQL Serv

    - by Aim Kai
    I am a relative newbie when it comes to SQL Azure!! I was wondering if there was a definitive list somewhere regarding what is and is not supported by SQL Azure in regards to SQL Server 2008? I have had a look through google but I've noticed some of the blog posts are missing things which I have found through my own testing: For example, quite a lot is summarised in this blog entry http://www.keepitsimpleandfast.com/2009/12/main-differences-between-sql-azure-and.html Common Language Runtime (CLR) Database file placement Database mirroring Distributed queries Distributed transactions Filegroup management Global temporary tables Spatial data and indexes SQL Server configuration options SQL Server Service Broker System tables Trace Flags which is a repeat of the MSDN page http://msdn.microsoft.com/en-us/library/ff394115.aspx I've noticed from my own testing that the following seem to have issues when migrating from SQL Server 2008 to the Azure: XML Types (the msdn does mention large custom types - I guess it may include this?? even if the data schema is really small?) Multi-part views I've been using SQL Azure Migration Wizard v3.1.8 to migrate local databases into the cloud. I was wondering if anyone could point to a list or give me any information till when these features are likely to be included in SQL Azure.

  • Getting a connection from a Sybase datasource in WAS 6.1 fails with message "User name property miss

    - by Abel Morelos
    I have a standalone application that needs to connect to a Sybase database via a datasource, I'm trying to connect using getConnection() and get the connection from this Sybase datasource which is hosted in WAS 6.1, sadly I'm getting an error JZ004 - Sybase(R) jConnect for JDBC(TM) Programmer's Reference: SQL Exception and Warning Messages JZ004 error message is: User name property missing in DriverManager.getConnection(..., Properties) Action: Provide the required user property. As you can see, this is not a connectivity (so we can discard JNDI or lookup problems), but rather a configuration problem. For my Sybase datasource in WAS 6.1 I have set up the proper authentication alias (Component-managed Authentication Alias), and I know the credentials are alright, "Test Connection" is successful for this datasource. Somebody had a similar problem and was because of the authentication alias- http://forum.springsource.org/showthread.php?t=39915 Next, I tried calling getConnection() but now I provided the credentials like getConnection(user, password)... and this time it worked!!! So I suspect that somehow WAS 6.1 is not picking or taking the authentication info I set in the datasource as mentioned before. If you think that maybe getConnection(user, password) should be OK for my case, well, that's not the case since I have a requirement to keep the credentials in the server, the standalone application only needs to know the JNDI information to lookup the datasource. Please let me know if have faced a similar problem, or what would you suggest me to do. Thanks.

  • error: expected constructor, destructor, or type conversion before '(' token

    - by jonathanasdf
    include/TestBullet.h:12: error: expected constructor, destructor, or type conver sion before '(' token I hate C++ error messages... lol ^^ Basically, I'm following what was written in this post to try to create a factory class for bullets so they can be instantiated from a string, which will be parsed from an xml file, because I don't want to have a function with a switch for all of the classes because that looks ugly. Here is my TestBullet.h: #pragma once #include "Bullet.h" #include "BulletFactory.h" class TestBullet : public Bullet { public: void init(BulletData& bulletData); void update(); }; REGISTER_BULLET(TestBullet); <-- line 12 And my BulletFactory.h: #pragma once #include <string> #include <map> #include "Bullet.h" #define REGISTER_BULLET(NAME) BulletFactory::reg<NAME>(#NAME) #define REGISTER_BULLET_ALT(NAME, CLASS) BulletFactory::reg<CLASS>(NAME) template<typename T> Bullet * create() { return new T; } struct BulletFactory { typedef std::map<std::string, Bullet*(*)()> bulletMapType; static bulletMapType map; static Bullet * createInstance(char* s) { std::string str(s); bulletMapType::iterator it = map.find(str); if(it == map.end()) return 0; return it->second(); } template<typename T> static void reg(std::string& s) { map.insert(std::make_pair(s, &create<T>)); } }; Thanks in advance.

  • Facebook Like Box not working

    - by Gabriel Bianconi
    Hello. I'm trying to integrate a Like box in my website. It wasn't working, so I created a sample page (which also doesn't work). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>FB TEST</title> </head> <body> <iframe src="http://www.facebook.com/plugins/likebox.php?profile_id=185550966885&amp;width=292&amp;connections=5&amp;stream=false&amp;header=true" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:292px; height:px"></iframe> </body> </html> I'm also using the sample iframe code (mine didn't work, so I tried this), taken from: http://developers.facebook.com/docs/reference/plugins/like-box How can I fix this?

  • SharePoint extensions for VS - which version have I got?

    - by Javaman59
    I'm using Visual Studio 2008, and have downloaded VSeWSS.exe 1.2, to enable Web Part development. I am new to SP development, and am already bewildered by the number of different versions of SP, and the VS add-ons. This particular problem has come up, which highlights my confusion. I selected Add - New Project - Visual C# - SharePoint- Web Part, accepted the defaults, and VS created a project, with the main file WebPart1.cs using System; using System.Runtime.InteropServices; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Serialization; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using Microsoft.SharePoint.WebPartPages; namespace WebPart1 { [Guid("9bd7e74c-280b-44d4-baa1-9271679657a0")] public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart { public WebPart1() { } protected override void CreateChildControls() // <-- This line { base.CreateChildControls(); // TODO: add custom rendering code here. // Label label = new Label(); // label.Text = "Hello World"; // this.Controls.Add(label); } } } The book I'm following, Essential SharePoint 2007, by Jeff Webb, has the following for the default project - using System; <...as previously> namespace WebPart1 { [Guid("9bd7e74c-280b-44d4-baa1-9271679657a0")] public class WebPart1 : System.Web.UI.WebControls.WebParts.WebPart { // ^ this is a new style (ASP.NET) web part! [author's comment] protected override void Render(HtmlTextWriter writer) // <-- This line { // This method draws the web part // TODO: add custom rendering code here. // Label label = new Label(); // writer.Write("Output HTML"); } } } The real reason for my concern is that in this chapter of the book the author frequently mentions the distinction between "old style" web parts, and "new style" web parts, as noted in his comment on the Render method. What's happened? Why has my default Web Part got a different signature to the authors?

  • Building a custom (dynamic) dataset and grid

    - by marko.ivanovski.nz
    Hi, I'm in the process of building a dynamic table in which you can add/remove rows & columns so it varies in size depending on what the user wants. Its purpose is to store properties for a product, but there can be from 1 to 10 different properties(columns) per product, and multiple instances(rows) of the product as well. Here's a screenshot of what I mean http://i40.tinypic.com/nbqkxc.jpg As you can see I need the structure to be completely up to the client which is where I'm getting stuck. I've started writing a custom DataSet that has "add column" & "add row" buttons, and have built a custom Table with Textboxes in each cell which builds from that dataset. I have no idea how to store the data on submit though, and to make it even more complex I need to store this in the database as a string which I think I can do by converting it to XML. Any help is appreciated, I think I just need a pointer in the right direction and am happy to do research from there. Thanks in advance. Marko

  • Windsor Method interception (AOP)

    - by Allan
    Hi there guys, I'm trying to create interceptors for specific methods but I'm having a hard time. I can't bind an aspect to a specific method. I create the faicilities most of examples show but it still doesn't work. Can anyone give me an example of how to do this? I prefer xml conifguration, if possible. Another question, I have this code: <component id="SampleAspect" service="WindsorSample.Aspect.SampleAspect, WindsorSample" type="WindsorSample.Aspect.SampleAspect, WindsorSample"> </component> <component id="HtmlTitleRetriever" type="WindsorSample.DummyObject, WindsorSample"> <parameters> <interceptors> <interceptor>${SampleAspect}</interceptor> </interceptors> </parameters> </component> Then... IWindsorContainer container = new WindsorContainer(new XmlInterpreter()); IDummyObject retriever = container.Resolve<DummyObject>(); retriever.SomeMethod(); This aspect is not executed. Am I missing something? Am I using the wrong approach for aop? Thanks

  • How do I stop the m2eclipse plugin interfering with command line mvn builds?

    - by locka
    I use the m2eclipse plugin in Eclipse so that I can import a Maven project. The plugin reads the pom.xml and sorts out the dependencies in the projects in an Eclipse friendly way so I'm not looking at a sea of broken references and errors. I use Eclipse for code development however I usually build the projects from the command line, e.g. "mvn clean install". Unfortunately when I do this, m2eclipse detects disk activity and attempts to rebuild the workspace. This interferes with the command line build and sometimes results in a race condition. For example the command line might be in its clean phase but fails because it tries to delete a file or directory which is locked during the workspace rebuild. Aside from that workspace rebuilding is incredibly slow, and between failed builds and wasted CPU my build process is 2-3x longer than it should be. It isn't an option to not use Eclipse (e.g. to use Netbeans), or to disable m2eclipse. It is a useful plugin except for this behaviour. So my question is, how do I stop m2eclipse from rebuilding the workspace all the time? Can I invoke a manual refresh and otherwise disable this behaviour?

  • StructureMap problems with bidirectional/circular dependencies

    - by leozilla
    I am currently integrating StructureMap within our business layer but have problems because of bidirectional dependencies. The layer contains multiple manager where each manager can call methods on each other, there are no restrictions or rules for communication. This also includes possible circular dependencies like in the example below. I know the design itself is questionable but currently we just want StructureMap to work and will focus on further refactoring in the future. Every manager implements the IManager interface internal interface IManager { bool IsStarted { get; } void Start(); void Stop(); } And does also have his own specific interface. internal interface IManagerA : IManager { void ALogic(); } internal interface IManagerB : IManager { void BLogic(); } Here are to dummy manager implementations. internal class ManagerA : IManagerA { public IManagerB ManagerB { get; set; } public void ALogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } internal class ManagerB : IManagerB { public IManagerA ManagerA { get; set; } public void BLogic() { } public bool IsStarted { get; private set; } public void Start() { } public void Stop() { } } Here is the StructureMap configuration i use atm. I am still not sure how i should register the managers so currently i use a manual registration. Maybee someone could help me with this too. For<IManagerA>().Singleton().Use<ManagerA>(); For<IManagerB>().Singleton().Use<ManagerB>(); SetAllProperties(convention => { // configure the property injection for all managers convention.Matching(prop => typeof(IManager).IsAssignableFrom(prop.PropertyType)); }); After all i cannot create IManagerA because StructureMap complians about the circular dependency between ManagerA and ManagerB. Is there an easy and clean solution to solve this problem but keep to current design? br David

  • C# - Class Type as Parameter in methods

    - by Claudio
    Hi guys, I'm using SQLite.cs wrapper for helping me with the database and I have this method for create XML from a table, that is working fine. public void GenerateInvoiceXML(string filePath) { var invoices = app.db.Table<Invoice>().ToList(); XmlSerializer serializer = new XmlSerializer( typeof(List<Invoice>) ); TextWriter writer = new StreamWriter(filePath); serializer.Serialize(writer,invoices); writer.Close(); } All tables that I have are defined like this: [Serializable] public class Invoice { [PrimaryKey, AutoIncrement] public int Id { get; set; } public string Supplier {get; set;} public string Date {get; set;} public string PaymentMethod {get; set;} public string Notes {get; set;} public Invoice(int newID) { Id = newID; } public Invoice() { } } But I want to change this method for something like this: public void GenerateInvoiceXML(string filePath, Type table) { var dataForXML = app.db.Table<table>().ToList(); XmlSerializer serializer = new XmlSerializer( typeof(List<table>) ); TextWriter writer = new StreamWriter(filePath); serializer.Serialize(writer,dataForXML); writer.Close(); } Does anybody have an idea how to do it?

  • NAnt errors when generating assembly info after project is upgraded to VS2010

    - by Grant Palin
    I have a project I recently upgraded to VS2010 - the project/solution files are updated, but I'm still targeting .NET 3.5. Until now, my standard NAnt build script has not given me any trouble. However, it appears that after updating the project, and updating the NAnt config to be aware of the new tooling, I am now receiving an error when autogenerating assembly information, which fails the build. The relevant build task is below: <asminfo output="${dir.src}\${file.commonAssemblyInfo}" language="${project.codeLanguage}"> <imports> <import namespace="System.Reflection" /> </imports> <attributes> <attribute type="AssemblyVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyFileVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyInformationalVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyCopyrightAttribute" value="${assembly.copyright}" /> <attribute type="AssemblyCompanyAttribute" value="${assembly.company}" /> <attribute type="AssemblyConfigurationAttribute" value="${project.config}" /> <attribute type="AssemblyTrademarkAttribute" value="${assembly.trademark}" /> <attribute type="AssemblyProductAttribute" value="${assembly.product}" /> </attributes> </asminfo> The error is highlighted for the first line of the asminfo task. It reads: AssemblyInfo file 'C:\Users\Grant\Projects\VisualStudio\Checklist\src\CommonAssemblyInfo.cs' could not be generated. This method implicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch. Please see http://go.microsoft.com/fwlink/?LinkID=155570 for more information. I've gathered so far that this is something new to .NET 4. Has anyone had to address this error before? Does anyone know what it is about asminfo that may be triggering the error?

  • Creating a scm browser for an RCP application.

    - by mdamman
    I have an RCP app that saves its project as an xml file and currently the user just selections a directory to save that file and then uses the open file dialog to open the project. We are thinking about enhancing it to allow users to check in/out from a source code manager. This will make it easier for users to share their projects with each others with all the benefits of a scm. I need something similar to Subclipses, but i was thinking of using the maven svn plugin so that it is more flexible which on which scm is used. It would probably better to keep it simple because most users won't have a clue what a scm is. An ideal would be just having a Checkout menu option which opens a dialog similar to the Open File dialog. I was wondering if anyone had an example of how to use the maven scm. What calls to make to set the scm location and to get the file? Or if there is a better way of going about this. Thanks!

  • Errors In Programmatically Running ANT Build In Eclipse

  • Register and Resolve Generic Interfaces Unity

    - by user1643791
    I am trying to register some generic interfaces and resolve them . I have the registering function private static void RegisterFolderAssemblies(Type t,string folder) { var scanner = new FolderGenericInterfaceScanner(); var scanned = scanner.Scan(t,folder); // gets the implementations from a specific folder scanned.ForEach(concrete => { if (concrete.BaseType != null || concrete.IsGenericType) { myContainer.RegisterType(t, Type.GetType(concrete.AssemblyQualifiedName), concrete.AssemblyQualifiedName); } }); } which is called by the bootstrapper with RegisterFolderAssemblies(typeof(IConfigurationVerification<>),Environment.CurrentDirectory); The registration seem to go through ok but when I try to Resolve them with Type generic = typeof(IConfigurationVerification<>); Type specific = generic.MakeGenericType(input.Arguments[0].GetType()); var verifications = BootStrap.ResolveAll(specific); The input.Arguments[0] is an object of the type the generic is implemented in I also tried using typeof(IConfigurationVerification<) instead and get the same error . When ResolveAll is public static List<object> ResolveAll(Type t) { return myContainer.ResolveAll(t).ToList(); } I get a ResolutionFailedException with them message "The current type, Infrastructure.Interfaces.IConfigurationVerification`1[Infrastructure.Configuration.IMLogPlayerConfiguration+LoadDefinitions], is an interface and cannot be constructed.

  • When is onBind or onCreate called in an android service browser plugin?

    - by anselm
    I have adapted the example plugin of the android source and the browser recognises the plugin without any problem. Here is an extract of AndroidManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <service android:name="com.domain.plugin.PluginService"> <intent-filter> <action android:name="android.webkit.PLUGIN" /> </intent-filter> </service> </application> <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.webkit.permission.PLUGIN"></uses-permission> The actual Service class looks like so: public class PluginService extends Service { @Override public IBinder onBind(Intent arg0) { Log.d("PluginService", "onBind"); return null; } @Override public void onCreate() { Log.d("PluginService", "onCreate"); // TODO Auto-generated method stub super.onCreate(); AssetInstaller.getInstance(this).installAssets("/data/data/com.domain.plugin"); } } The AssetInstaller code is supposed to extract some files required by the actual plugin into the /data/data/com.domain.plugin directory, however wether onBind nor onCreate are called. But I get lot's of debug trace of the actual libnpplugin.so file I'm using. So the puzzle is when and under what circumstance is the Service bound or created in case of a browser plugin. As things look the service seems to be a dummy service. Having said that, is there another intent that can be executed at installation time probably? The only solution I see right now is installing the needed files from the native plugin code instead. Any ideas? I know this is quite a tricky question ;)

  • Perl cron job stays running

It runs fine from the command line and also interprets the 'cycle' argument fine. When it runs in cron it runs fine, however, the process never dies and while each process doesn't continue to cycle the system it does seem to be looping in some way due to the fact that it ups my system load very quickly. If you'd like more information, just ask.

  • Spring - Transaction Readonly

    - by AAK
    Hello Gurus! Just wanted your expert opinions on declarative transaction management for Spring. Here is my setup - A. DAO Layer is Plain old JDBC using jdbcTemplete (No hibernate etc) B. Service Layer is POJO with declarative trasnactions as follows - save*, readonly=false, rollback for Throwable Things work fine with above setup. However when I say get*, readonly=true I see errors in my log file saying - Database connection cannot be marked as readonly. This happens for all get* methods in Service Layer. Now my questions - A. Do I have to say get* as readonly? All my get* methods are pure read DB operations. I do not wish to run them in any transaction context. How serious is the above error? B. When I remove the get* confiiguration, I do not see the errors, morever all my simple get* operations are performed without transactions. Is this the way to go? C. Why would anyone want to have transactional methods where readonly = true? Is there any practical significance of this configuration? Thank you! As always your resposes are much appreciated!

  • Deleting a non-owned dynamic array through a pointer

    - by ayanzo
    Hello all, I'm relatively novice when it comes to C++ as I was weened on Java for much of my undergraduate curriculum (tis a shame). Memory management has been a hassle, but I've purchased a number books on ansi C and C++. I've poked around the related questions, but couldn't find one that matched this particular criteria. Maybe it's so obvious nobody mentions it? This question has been bugging me, but I feel as if there's a conceptual point i'm not utilizing. Suppose: char original[56]; cstr[0] = 'a'; cstr[1] = 'b'; cstr[2] = 'c'; cstr[3] = 'd'; cstr[4] = 'e'; cstr[5] = '\0'; char *shaved = shavecstr(cstr); delete[] cstrn; where char* shavecstr(char* cstr) { size_t len = strlen(cstr); char* ncstr = new char[len]; strcpy(ncstr,cstr); return ncstr; } In that the whole point is to have 'original' be a buffer that fills with characters and routinely has its copy shaved and used elsewhere. To prevent leaks, I want to free up the memory held by 'shaved' to be used again after it passes through some arguments. There is probably a good reason for why this is restricted, but there should be some way to free the memory as by this configuration, there is no way to access the original owner (pointer) of the data.

  • Simple Enterprise Library console application refuses to compile

    - by Vadim
    I just downloaded and installed Microsoft Enterprise Library 5.0. I fired up VS 2010 to play with EL 5 and created a very simple console application. However, it would not compile. I got the following error: The type or namespace name 'Data' does not exist in the namespace 'Microsoft.Practices.EnterpriseLibrary' (are you missing an assembly reference?) I added Microsoft.Practices.EnterpriseLibrary.Common, Microsoft.Practices.EnterpriseLibrary.Data, and Microsoft.Practices.Unity references to my project. Here's the simple code that refuses to compile. using Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Unity; using Microsoft.Practices.EnterpriseLibrary.Data; using Microsoft.Practices.Unity; namespace EntLib { class Program { static void Main(string[] args) { IUnityContainer container = new UnityContainer(); container.AddNewExtension<EnterpriseLibraryCoreExtension>(); var defaultDatabase = container.Resolve<Database>(); } } } The error above complains about line #2 : using Microsoft.Practices.EnterpriseLibrary.Data; Someone probably will point out to a stupid mistake by me, but at the moment I fail to see it. I tried to remove and add again Microsoft.Practices.EnterpriseLibrary.Data to refences but it didn't help.

  • WPF XAML references not resolved via myAssembly.GetReferencedAssemblies()

    - by WPF-it
    I have a WPF container application (with ContentControl host) and a containee application (UserControl). Both are oblivious of each other. Only one XML config file holds the string dllpath of the containee's DLL and full namespace name of the ViewModelClass inside the containee. A generic code in container resolves containee's assembly (Assembly.LoadFrom(dllpath)) and creates the viewmodel's instance using Activator.CreateInstance(vmType). when this viewmodel is hosted inside the ContentControl of the container, and relevant vierwmodel specific ResourceDictionary is added to ContentControl.Resources.MergedDictionaries of the content control of container, so the view loads fine. Now my containee has to host the WPF DataGrid using assembly reference of WPFToolkit.dll from my local C:\Lib folder. The Copy Local reference to the WPFToolkit.dll is added to the .csproj file of the containee's project and its only referred in the UserControl.XAML using its XAML namepsace. This way my bin\debug folder in my containee application, gets the WPFToolkit.dll copied. XAML: xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" <Controls:DataGrid ItemsSource="{Binding AssetList}" ... /> Issue: The moment the ViewModel (i.e. the containee's usercontrol) tries to load itself I get this error. "Cannot find type 'Microsoft.Windows.Controls.DataGrid'. The assembly used when compiling might be different than that used when loading and the type is missing." Hence I tried to load the referenced assemblies of the containee's assembly (myAssembly.GetReferencedAssemblies()) before the viewmodel is hosted. But WPFToolkit isnt there in that list of assemblies! Strange thing is I have another dll referred called Logger.dll in the containee codebase but this one is implemented using C# code behind. So I get its reference correctly resolved in myAssembly.GetReferencedAssemblies(). So does that mean BAML references of assemblies are never resolvable by GetReferencedAssemblies?

  • VS2010 express beta2 - no add reference dialog, no open file/project dialogs

    - by David
    Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.
