  • VS2010 asking to upgrade SIlverlight??

    - by Lu10ntDan
    I'm running the absolute latest versions of Silverlight and Visual Studio 2010 Professional and built a solution that contained a WPF project. From there, I added a SketchFlow project (based on Blend 4 RC) and I can run each project within the solution just fine by setting whenever I switch between them as startup projects. From there, I added a Silverlight 4 Business Application (taking all the defaults), and when simply trying to set that as the startup project and running it, VS2010 is giving me the following error after trying to open a web page: Line: 56 (in file TestPage.aspx) Error: Unhandled Error in Silverlight Application Code: 8001 Category: InitializeError Message: Upgrade required If I choose not to debug, I get the Silverlight page saying "This page requires a more recent version of Silverlight"! Clicking "Install Now" on the popup window brings me to Mirosoft's Silverlight page where I see: "The version of Silverlight originally requested is not available. You can get a supported version from this page. This Web browser or operating system may not be compatible with Silverlight. Please review the system requirements and, if you wish to proceed, choose the link for your operating system." If I choose to upgrade anyway, I'm told that I'm running the latest version of Silverlight available. What the heck? I'm running the final versions of VS2010 Pro, Silverlight 4, and the latest version of Expression Blend 4 (RC). Why can't VS2010 run this default Silverlight Business App? Any ideas? Please?? Thanks, Lu10ntDn PS. This is on Windows 7 with UAC turned off, and ALL latest Windows Updates installed.

  • Best practices on using URIs as parameter value in REST calls.

    - by dafmetal
    I am designing a REST API where some resources can be filtered through query parameters. In some cases, these filter values would be resources from the same REST API. This makes for longish and pretty unreadable URIs. While this is not too much of a problem in itself because the URIs are meant to be created and manipulated programmatically, it makes for some painful debugging. I was thinking of allowing shortcuts to URIs used as filter values and I wonder if this is allowed according to the REST architecture and if there are any best practices. For example: I have a resource that gets me Java classes. Then the following request would give me all Java classes: GET http://example.org/api/v1/class Suppose I want all subclasses of the Collection Java class, then I would use the following request: GET http://example.org/api/v1/class?has-supertype=http://example.org/api/v1/class/collection That request would return me Vector, ArrayList and all other subclasses of the Collection Java class. That URI is quite long though. I could already shorten it by allowing hs as an alias for has-supertype. This would give me: GET http://example.org/api/v1/class?hs=http://example.org/api/v1/class/collection Another way to allow shorter URIs would be to allow aliases for URI prefixes. For example, I could define class as an alias for the URI prefix http://example.org/api/v1/class/. Which would give me the following possibility: GET http://example.org/api/v1/class?hs=class:collection Another possibility would be to remove the class alias entirely and always prefix the parameter value with http://example.org/api/v1/class/ as this is the only thing I would support. This would turn the request for all subtypes of Collection into: GET http://example.org/api/v1/class?hs=collection Do these "simplifications" of the original request URI still conform to the principles of a REST architecture? Or did I just go off the deep end?

  • Trace PRISM / CAL events (best practice?)

    - by Christian
    Ok, this question is for people with either a deep knowledge of PRISM or some magic skills I just lack (yet). The Background is simple: Prism allows the declaration of events to which the user can subscribe or publish. In code this looks like this: _eventAggregator.GetEvent<LayoutChangedEvent>().Subscribe(UpdateUi, true); _eventAggregator.GetEvent<LayoutChangedEvent>().Publish("Some argument"); Now this is nice, especially because these events are strongly typed, and the declaration is a piece of cake: public class LayoutChangedEvent : CompositePresentationEvent<string> { } But now comes the hard part: I want to trace events in some way. I had the idea to subscribe using a lambda expression calling a simple log message. Worked perfectly in WPF, but in Silverlight there is some method access error (took me some time to figure out the reason).. If you want to see for yourself, try this in Silverlight: eA.GetEvent<VideoStartedEvent>().Subscribe(obj => TraceEvent(obj, "vSe", log)); If this would be possible, I would be happy, because I could easily trace all events using a single line to subscribe. But it does not... The alternative approach is writing a different functions for each event, and assign this function to the events. Why different functions? Well, I need to know WHICH event was published. If I use the same function for two different events I only get the payload as argument. I have now way to figure out which event caused the tracing message. I tried: using Reflection to get the causing event (not working) using a constructor in the event to enable each event to trace itself (not allowed) Any other ideas? Chris PS: Writing this text took me most likely longer than writing 20 functions for my 20 events, but I refuse to give up :-) I just had the idea to use postsharp, that would most likely work (although I am not sure, perhaps I end up having only information about the base class).. Tricky and so unimportant topic...

  • Maintain denormalized data with NHibernate EventListener

    - by Michael Valenty
    I have one bit of denormalized data used for performance reasons and I'm trying to maintain the data with an NHibernate event listener rather than a trigger. I'm not convinced this is the best approach, but I'm neck deep into it and I want to figure this out before moving on. I'm getting following error: System.InvalidOperationException : Collection was modified; enumeration operation may not execute. System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource) System.Collections.Generic.List`1.Enumerator.MoveNextRare() System.Collections.Generic.List`1.Enumerator.MoveNext() NHibernate.Engine.ActionQueue.ExecuteActions(IList list) NHibernate.Engine.ActionQueue.ExecuteActions() NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions (IEventSource session) NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) NHibernate.Impl.SessionImpl.Flush() NHibernate.Transaction.AdoTransaction.Commit() Here's the code to make happen: using (var tx = session.BeginTransaction()) { var business = session .Get<Business>(1234) .ChangeZipCodeTo("92011"); session.Update(business); tx.Commit(); // error happens here } and the event listener: public void OnPostUpdate(PostUpdateEvent @event) { var business = @event.Entity as Business; if (business != null) { var links = @event.Session .CreateQuery("select l from BusinessCategoryLink as l where l.Business.BusinessId = :businessId") .SetParameter("businessId", business.BusinessId) .List<BusinessCategoryLink>(); foreach (var link in links) { link.Location = business.Location; @event.Session.Update(link); } } }

  • gwt maven war plugin configuration problem

    - by Din
    I am developing a gwt application in maven. In this I am using maven war plugin. Everything works fine. When I give mvn install command it builds abc.war file in target folder.

  • What is wrong with my Basic Authentication in my Browser?

    - by Pure.Krome
    Hi folks, i'm trying to goto the following url :- http://user1:pass1@localhost:1234/api/users?format=xml nothing to complex. Notice how i've got the username/password in the url? this, i believe, is for basic authentication. When I do that, the Request Headers are MISSING the 'Authorize' header. Er... that's not right :( I have anonymous authentication only setup on the site. I don't want to have anon off and basic turned on .. because not all of the site requires basic.. only a few action methods. So .. why is this not working? Is this something to do with the fact my code is not sending a 401 challenge or some crap? For What It's Worth, my site is ASP.NET MVC1 running on IIS7 (and the same thing happens when i run it on cassini). Update: If this is an illegal way of calling a resource using basic auth (ala security flaw) .. then is this possible to do, for an ASP.NET MVC website .. per action method (and not the entire site, per say)?

  • When should I be cautious using about data binding in .NET?

    - by Ben McCormack
    I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this: Dim dt as DataTable = FuncLib.GetData("spGetTheData ...") Dim i As Integer For i = 0 To dt.Rows.Length - 1 '(not sure why we do not use a for each here)' gridRow = grid.Rows.Add() gridRow(constantProductID).Value = dt("ProductID").Value gridRow(constantProductDesc).Value = dt("ProductDescription").Value Next '(I am probably missing something in the code, but that is basically it)' Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand. The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data. When should I be cautious of using data-binding in .NET?

  • Core Data - Entity Relationships Not Working as expected

    - by slimms
    I have set up my data model in xcode like so EntityA AttA1 AttA2 EntityB AttB1 AttB2 AttB3 I then set up the relationships EntityA Name: rlpToEntityB Destination: EntityB Inverse: rlpToEntityA To Many: Checked EntityB Name: rlpToEntityA Destination: EntityA Inverse: rlpToEntityB To Many: UnChecked i.e. relationship between the two where Each one of EntityA can have many EntityB's It is my understanding that if i fetch a subset of EntityB's I can then retrieve the values for the related EntityA's. I have this working so that i can retrieve the EntityB values using NSManagedObject *objMO = [fetchedResultsController objectAtIndexPath:indexPath]; strValueFromEntityB = [objMO valueForKey:@"AttB1"]; However, if I try to retrieve a related value from EntityA by doing the following strValueFromEntityA = [objMO valueForKey:@"AttA1"]; I get the error "The entity EntityB is not Key value coding-compliant for the key Atta1" Not surprisingly i suppose if i switch things around to fetch from EntityA i cannot access attributes of EntityB So it appears the defined relationshipare being ignored. Can anyone spot what i am doing wrong? I confess im very new to iPhone programming and especially to Core Data so please go easy on me and provide verbose explanations or point me in the direction a specific resource. I have downloaded the apple sample apps (Core Data Books, Top Songs and recipes) but I still can't work this out. Thanks in advance, Nev.

  • CPU friendly infinite loop

    - by Adi
    Writing an infinite loop is simple: while(true){ //add whatever break condition here } But this will trash the CPU performance. This execution thread will take as much as possible from CPU's power. What is the best way to lower the impact on CPU? Adding some Thread.Sleep(n) should do the trick, but setting a high timeout value for Sleep() method may indicate an unresponsive application to the operating system. Let's say I need to perform a task each minute or so in a console app. I need to keep Main() running in an "infinite loop" while a timer will fire the event that will do the job. I would like to keep Main() with the lowest impact on CPU. What methods do you suggest. Sleep() can be ok, but as I already mentioned, this might indicate an unresponsive thread to the operating system. LATER EDIT: I want to explain better what I am looking for: I need a console app not Windows service. Console apps can simulate the Windows services on Windows Mobile 6.x systems with Compact Framework. I need a way to keep the app alive as long as the Windows Mobile device is running. We all know that the console app runs as long as its static Main() function runs, so I need a way to prevent Main() function exit. In special situations (like: updating the app), I need to request the app to stop, so I need to infinitely loop and test for some exit condition. For example, this is why Console.ReadLine() is no use for me. There is no exit condition check. Regarding the above, I still want Main() function as resource friendly as possible. Let asside the fingerprint of the function that checks for the exit condition.

  • Raphael JS image animation performance.

    - by michael
    Hi, I'm trying to create an image animation using Raphael JS. I want the effect of a bee moving randomly across the page, I've got a working example but it's a bit "jittery", and I'm getting this warning in the console: "Resource interpreted as image but transferred with MIME type text/html" I'm not sure if the warning is causing the "jittery" movement or its just the way I approached it using maths. If anyone has a better way to create the effect, or improvements please let me know. I have a demo online here and heres my javascript code: function random(min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; } function BEE(x, y, scale) { this.x = x; this.y = y; this.s = scale; this.paper = Raphael("head", 915, 250); this.draw = function() { this.paper.clear(); this.paper.image("bee.png", this.x, this.y, 159*this.s, 217*this.s); } this.update = function() { var deg = random(-25, 25); var newX = Math.cos(Raphael.rad(deg)) * 2; var newY = Math.sin(Raphael.rad(deg)) * 2; this.x += newX; this.y += newY; if( this.x > 915) { this.x = 0; } if( this.y > 250 || this.y < 0 ) { this.y = 125; } } } $(document).ready(function() { var bee = new BEE(100, 150, 0.4); var timer = setInterval(function(){ bee.draw(); bee.update(); }, 15); }

  • What does stdole.dll do?

    - by rc1
    We have a large C# (.net 2.0) app which uses our own C++ COM component and a 3rd party fingerprint scanner library also accessed via COM. We ran into an issue where in production some events from the fingerprint library do not get fired into the C# app, although events from our own C++ COM component fired and were received just fine. Using MSINFO32 to compare the loaded modules on a working system to those on a failing system we determined that this was caused by STDOLE.DLL not being in the GAC and hence not loaded into the faulty process. Dragging this file into the GAC caused events to come back fine from the fingerprint COM library. So what does stdole.dll do? It's 16k in size so it can't be much... is it some sort of link to another library like STDOLE32? How come its absence causes such odd behavior? How do we distribute stdole.dll? This is an XCOPY deploy app and we don't use the GAC. Should we package it as a resource and use the System.EnterpriseServices.Internal.Publish.GacInstall to ensure it's in the GAC?

  • How can I edit an exe's resources (File Description, Icon, etc.) using a command line utility?

    - by Coder7862396
    The whole story: I have created a fancy .NET program which has an installer created by the Visual Studio Installer (VSI). The VSI creates 2 files (setup.exe and MyProgramSetup.msi). I understand the reasons for both files being needed, however, I only want to distribute a SINGLE executable installer to users. I do not want them to see 2 files and have to choose between them. In order to do this I have merged the 2 files into a self-extracting archive using IExpress (as seen in this answer: http://stackoverflow.com/questions/535966/merge-msi-and-exe). This works well, however, the self-extracting archive that gets created has an ugly icon and confusing file info (the File Description is "Win32 Cabinet Self-Extractor" with 43 black spaces after it). I need to replace the icon with my custom one and change some of the file properties like "Description", "Company", etc. I would like to have this automatically done as a build step so having a program which is a command line/console utility would be great. I've searched for a while now and can only find one program which does exactly what I want (ResourceTuner Console: http://www.heaventools.com/command-line_resource_editor.htm) but it costs an arm and a leg and my budget is $0. Does anyone know a better way to achieve what I want, or know of a program which can replace an executable's resources without having to use a GUI? By the way, I have also tried "SiComponents Resource Builder 3" which can't even open the executable, and "Julien Audo's ResEdit" which just crashes when I execute the command: "resedit.exe -convert "Modified Resources.rc" "MyProgramSetup.exe"

  • Apache multiple URL to one domain redirect

    - by Christian Moser
    For the last two day, I've been spending a lot of time to solve my problem, maybe someone can help me. Problem: I need to redirect different url's to one tomcat webbase-dir used for artifactory. following urls should point to the tomcat/artifactory webapp: maven-repo.example.local ; maven-repo.example.local/artifactory ; srv-example/artifactory Where maven-repo.example.local is the dns for the server-hostname: "srv-example" I'm accessing the tomcat app through the JK_mod module. The webapp is in the ROOT directory This is what I've got so far: <VirtualHost *:80> #If URL contains "artifactory" strip down and redirect RewriteEngine on RewriteCond %{HTTP_HOST} ^\artifactory\$ [NC] # (how can I remove 'artifactory' from the redirected parameters? ) RewriteRule ^(.*)$ http://maven-repo.example.local/$1 [R=301,L] ServerName localhost ErrorLog "logs/redirect-error_log" </VirtualHost> <VirtualHost *:80> ServerName maven-repo.example.local ErrorLog "logs/maven-repo.example.local-error.log" CustomLog "logs/maven-repo.example.local-access.log" common #calling tomcat webapp in ROOT JkMount /* ajp13w </VirtualHost> The webapp is working with "maven-repo.example.local", but with "maven-repo.example.local/artifactory" tomcat gives a 404 - "The requested resource () is not available." It seems that the mod_rewrite doesn't have taken any effect, even if I redirect to another page, e.g google.com I'm testing on windows 7 with maven-repo.example.local added in the "system32/drivers/hosts" file Thanks in advance!

  • Calling ASP.NET Web API using JQuery ajax - cross site scripting issue

'+errorThrown); } }); ...but when I trace it using FireBug Lite the response comes from port 82: {"Message":"No HTTP resource was found that matches the request URI 'http://127.0.0.1:82/api/people'.","MessageDetail":"No action was found on the controller 'People' that matches the request."} I think the error is, effectively, due to cross-site scripting being blocked, but I'm not actually cross-site scripting, if you see what I mean. Has anyone else come across this and been able to fix it? Edit: Routing config (global.asax.vb) is: RouteTable.Routes.MapHttpRoute(name:="DefaultApi", routeTemplate:="api/{controller}/{id}", defaults:=New With {Key .id = System.Web.Http.RouteParameter.Optional}) Controller: Public Function PostValue(ByVal departmentid As Integer, ByVal emailaddress As String, ByVal firstname As String, ByVal lastname As String) As Guid Dim context As New WSMModelDataContext Dim bllPeople As New PeopleBLL(context) Return bllPeople.Create(firstname, lastname, emailaddress, departmentid) End Function When I debug it, it doesn't get as far as running the controller, although when calling it through RESTEasy it routes correctly and the controller executes successfully. The only difference seemes to be that wen called through RESTEasy it is (correctly) using http://127.0.0.1:81 but for some reason when called via JQuery/ajax it seems to be using http://127.0.0.1:82.

  • Is There a Time at which to ignore IDisposable.Dispose?

    - by Mystagogue
    Certainly we should call Dipose() on IDisposable objects as soon as we don't need them (which is often merely the scope of a "using" statement). If we don't take that precaution then bad things, from subtle to show-stopping, might happen. But what about "the last moment" before process termination? If your IDisposables have not been explicitly disposed by that point in time, isn't it true that it no longer matters? I ask because unmanaged resources, beneath the CLR, are represented by kernel objects - and the win32 process termination will free all unmanaged resources / kernel objects anyway. Said differently, no resources will remain "leaked" after the process terminates (regardless if Dispose() was called on lingering IDisposables). Can anyone think of a case where process termination would still leave a leaked resource, simply because Dispose() was not explicitly called on one or more IDisposables? Please do not misunderstand this question: I am not trying to justify ignoring IDisposables. The question is just technical-theoretical. EDIT: And what about mono running on Linux? Is process termination there just as "reliable" at cleaning up unmanaged "leaks?"

  • A business Case for Enterprise Python

    - by Srirangan
    Hi all, This will not be a "programming" question but more technology / platform related question. I'm trying to figure out whether Python can be a suitable Java alternative for enterprise / web applications. Which are the ideal cases where you would prefer to use Python instead of Java? How would a typical Python web application (databases/sessions/concurrency) perform as compared to a typical Java application? How do specific Python frameworks square up against Java based frameworks (Spring, SEAM, Grails etc.)? For businesses, switching from the Java infrastructure to a Python infrastructure .. is it too hard/expensive/resource intensive/not viable? Also shed some light on the business case for providing a Python + Google AppEngine based solution to the end customer. Will it be cost effective in an typical scenario? Sorry if I am asking too wide a question, I would have liked to keep it specific, but I need your help to evaluate Python as a whole from the perspectives of the programmers, service providing company and end business customer. For an SME, a Python/GoogleAppEngine based technology stack is a clear scalable and affordable platform. But what about a large MNC that already has a lot invested in Java. Thank you so much. I am researching this myself and will gladly share my conclusions here! Thank you, Srirangan

  • Upgrading VSTO project to .net 4 - What references do I actually need?

    - by Dana
    I'm developing an application for Office. It originally targeted .net 3.5, but I decided to upgrade to .net 4 because of some WPF issues that I've run into. When I switched all the projects in my solution and rebuilt, I got an error saying to include System.Xaml. I did that and rebuilt, and VS2010 told me to include another reference, so I did. This happened a couple more times, and finally it asked me to include Microsoft.Office.Tools.Common.v9.0, and when I did I got this error: Microsoft.Office.Tools.CustomTaskPaneCollection exists in both Microsoft.Office.Tools.Common.v9.0.dll and Microsoft.Office.Tools.Common.dll I have both Microsoft.Office.Tools.Common.v9.0 and Microsoft.Office.Tools.Common referenced in my project, but the problem is that if I remove either, I get an error. Am I doing something wrong? Is it odd that I would need both references? I find it strange that CustomTaskPaneCollection would be defined in two different binaries. If I remove Microsoft.Office.Tools.Common, the error that I get is "Cannot find the interop type that matches the embedded interop type 'Microsoft.Office.Tools.IAddInExtension'. Are you missing an assembly reference?"

  • How can I load a Class contained in a website from a DLL referenced by that website???

    - by Morgeh
    Ok so this is alittle bit obscure and I'm not sure its the best way of doing what I'm trying to do but here goes. Basically I have a Presentation Layer Dll in my web site which handles the Model View Presenter classes. The presentation layer also handles login for my website and then calls off to a web service. Currently whenever the presentation layer calls to a model it verifies the users details and if they are invalid it calls to a loginHandler which redirects the user to the login page. However I cannot dynamically load a new istance of the Login Page in my website from within my Presentation layer. I've tried to use reflection to dynamically load the class but Since the method call is in the presentation assembly it is only looking within that assembly while the page I want to load is in the website. heres the reflection code that loads the View: public ILoginView LoadView() { string viewName = ConfigurationManager.AppSettings["LoginView"].ToString(); Type type = Type.GetType(viewName, true); object newInstance = Activator.CreateInstance(type); return newInstance as ILoginView; } Anyone got any suggestions on how to search within the website assembly? Ideal I don't want to tie this implementation into the website specifically as the presentation layer is also used in a WPF application.

  • Destroying nested resources in restful way

    I'm looking for help destroying a nested resource in Merb. My current method seems near correct, but the controller raise an InternalServerError during the destruction of the nested object.

  • Why can't I create a database in an empty ASP MVC 2 project using Project->Add->New Item->SQL Server

    - by Dr Dork
    I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error when trying to add a new database to my fresh, empty ASP MVC 2 project... A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something. This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions... What am I missing/forgetting to do that is causing this error? Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL). Thanks so much in advance for all your help! I'm going to start researching these questions right now.

  • Mimic remote API or extend existing django model

    - by drozzy
    I am in a process of designing a client for a REST-ful web-service. What is the best way to go about representing the remote resource locally in my django application? For example if the API exposes resources such as: List of Cars Car Detail Car Search Dealership summary So far I have thought of two different approaches to take: Try to wrangle the django's models.Model to mimic the native feel of it. So I could try to get some class called Car to have methods like Car.objects.all() and such. This kind of breaks down on Car Search resources. Implement a Data Access Layer class, with custom methods like: Car.get_all() Car.get(id) CarSearch.search("blah") So I will be creating some custom looking classes. Has anyone encoutered a similar problem? Perhaps working with some external API's (i.e. twitter?) Any advice is welcome. PS: Please let me know if some part of question is confusing, as I had trouble putting it in precise terms.
