• The type or namespace name 'Mvc' does not exist in the namespace 'System.Web'

  - by Guy

  After converting a Hybrid ASP.NET MVC1 app to MVC2 I'm getting the following error when I try and run the application: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) The allegeded culprit in the web.config file is System.Web.Mvc: <namespaces> <add namespace="System.Web.Mvc"/> <add namespace="System.Web.Mvc.Ajax"/> <add namespace="System.Web.Mvc.Html"/> So far my investigation seems to lead me to believe that version 2 of System.Web.Mvc is not installed or has not been picked up. I've tried creating a File New Project based on MVC 2 and that's picking up the new (v2) version of MVC. I've also converted some other projects (that were not hybrids) and they've converted without problem to MVC2. I've also uninstalled MVC1 to try and remove references to it from the GAC. However, none of this has worked. Any ideas?

• Does IsolatedStorageFileStream.Lock work under SIlverlight4?

  - by Noah

  Silverlight uses an IsolatedStorageFileStream to open files. The IsolatedStorageFileStreamunder NET.4 claims to support the Lock Method (Inherited from FileStream) The following code IsolatedStorageFile isf; IsolatedStorageFileStream lockStream = new IsolatedStorageFileStream( "my.lck", FileMode.OpenOrCreate, isf ); lockStream.Lock( 0, 0 ); generates the following error, wrapped for readability, under VS2010 and Silverlight 4 'System.IO.IsolatedStorage.IsolatedStorageFileStream' does not contain a definition for 'Lock' and no extension method 'Lock' accepting a first argument of type 'System.IO.IsolatedStorage.IsolatedStorageFileStream' could be found (are you missing a using directive or an assembly reference?)

• Android: ContentObserver selfChange

  - by mattprecious

  Hi, In the ContentObserver class, the method onChange is passed a boolean selfChange that's defined as: "true if the update was caused by a call to commit on the cursor that is being observed." What's the proper way to update the cursor so that selfChange is set to true? My current code doesn't reference the cursor at all for an update and selfChange is always false as a result. ContentValues values = new ContentValues(); values.put("date", date.getTime()); getContentResolver().update(URI, values, "_id = " + id, null);

• Good embedded database solution (like SQLite) for .Net

  - by vfilby

  I am looking for file based storage solutions that I can use with a .Net project. THey need to have a sql-like interface for storing and retrieving data. They need to have relatively little overhead and must not require any additional components installed by the end user. I am hopping for a .dll that I can reference and use. Cool points awarded if it is closely tied to an ORM. My current favourite is SQLite, are there any better ones out there that I should know about? I have a (health?) bias against access because I feel it is overcomplicated for what I need, I am open to being convinced otherwise though. PS: "No, there is nothing better than SQLite" is a perfectly good answer.

• Why does Sitecore throw a NullReferenceException exception when I redirect to one of its pages?

  - by Abs

  I'm running Sitecore 6.1 on Windows 2008, IIS7, and I'm trying to use the URL Rewrite Module to do a redirect. When I enable the rule and hit the URL that triggers it, I get a YSOD. The same rule works perfectly on a non-sitecore site on the same machine. According to the Failed Request Trace, the rewrite module does its thing just fine, but then Sitecore throws an exception, even if the redirect points to another server. This is probably a result of something I have misconfigured, but I just can't understand why it doesn't work. The details from the YSOD are below. [NullReferenceException: Object reference not set to an instance of an object.] Sitecore.Nexus.Web.HttpModule.(Object sender, EventArgs e) +273 System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +68 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

• How to use htaccess to rewrite url to html anchor tag (#)

  - by Lee L

  Hi - I have a situation where I want to take the following URL: /1/john and have it redirect using Apache's htaccess file to go to /page.php?id=1&name=john#john so that it goes to an html anchor with the name of john. I've found a lot of reference to escaping special characters, and to adding the [NE] flag so that the redirect ignores the # sign, but these don't work. For example, adding [NE,R] means that the URL just appears in the browser address as the original: http://mysite.com/page.php?id=1&name=john#john. Any help would be appreciated.

• Reverse geocode without using MKReverseGeocoder

  - by SpH1nX

  Hi guys, I'm trying to detect current user address using MKReverseGeocoder passing coordinates obtained via CLLocation class. Reading MKReverseGeocoder Class Reference I noticed that The Google terms of service require that the reverse geocoding service be used in conjunction with a Google map; take this into account when designing your application's user interface. so I'm wondering if (and eventually how) can I reverse geocode user current location on iPhone OS SDK 3.1.3. I thought using Google Maps API but the EULA has the same obligation. Yahoo Maps API is even worse and Microsoft one aren't free.

• HTTP Authentication with Web References

  - by Thor

  I have a web reference created from the WSDL, but I'm not allowed to call the function unless I pass in the username / password; the original code for the XML toolkit was: Set client = CreateObject("MSSOAP.SOAPClient30") URL = "http://" & host & "/_common/webservices/Trend?wsdl" client.mssoapinit (URL) client.ConnectorProperty("WinHTTPAuthScheme") = 1 client.ConnectorProperty("AuthUser") = user client.ConnectorProperty("AuthPassword") = passwd On Error GoTo err Dim result1() As String result1 = client.getTrendData(expression, startDate, endDate, limitFromStart, maxRecords How do I add the AuthUser/AuthPassword to my new code? New code: ALCServer.TrendClient tc = new WindowsFormsApplication1.ALCServer.TrendClient(); foreach(string s in tc.getTrendData(textBox2.Text, "5/25/2009", "5/28/2009", false, 500)) textBox1.Text+= s;

• PartCover shows 0% coverage for getter and 100% coverage for setter despite the code being commented

  - by Gorgsenegger

  Hi all, I have a public property in my code as below: [DependencyInjection] public IEVentController EventController { get; set; } I also have a line of code referencing the EventController property: EventController.ExecuteObjectEvents( someObject, null ); Now currently (due to some missing implementation in another part of the application) I commented both these code sections out. Nevertheless, when I run PartCover it shows me a coverage of 0% for get_EventController and 100% for set_EventController. The strange thing is, that the Coverage Details view also correctly shows me that the code is commented out and therefore should not be treated as code - why does PartCover recognise it anyway? I would have expected to not get the getter and setter listed in the PartCover result. There is definitely no other reference to that code in the class to be tested, any ideas? Thanks in advance & Best regards G.

• Masked Edit extender inside a Repeater

  - by Viswa

  How can i dynamically create a textBox and a Masked Edit extender inside a Panel. My code is something like this: In the ASPX page: In the Aspx.cs page Private DataView Function1() { Dataview dv =new dataview(); return dv; } Private void ShowProducts_OntemDataBound(object sender, RepeaterEventItem e) { //Consider For the First Iteration of the Repeater I am Creating a Simple Text Box Dynamically Textbox txt = new textbox(); txt.Text = "8888888888"; txt.Id = "TextBox1"; //Consider For the Second Iteration of the Repeater I am Creating another TextBox and a Textbox txt1 = new textBox(); txt1.text="2223334444"; txt1.Id = "TextBox2"; MaskedEditExtender mskEdit = (MaskedEditExtender)e.Item.FindControl("MskEdit"); mskEdit.TargetControlId = txt1.Id; Panel panel1 = (Panel)e.item.Findcontrol("Panel1"); panel1.Controls.Add(txt1); } When running the above code it is giving me "Null Reference Exception for MaskedEditExtender".Please suggest me some way for this.

• Building a list of favorites from Core Data

  - by Jim

  I'm building an app with two tabs. The first tab has a main tableview that connects to a detail view of the row. The second tab will display a tableView based on the user adding content to it by tapping a button on the detail view. My question is this. What is the correct design pattern to do this? Do I create a second ManagedObjectContext/ManagedObjectContextID then save that context to a new persistent store or can the MOC be saved to the existing store without affecting the original tableview? I've looked at CoreData Recipes and CoreData Books and neither deal with multiple stores although books does deal with multiple MOC's. Any reference would be great.

• datamapper secondary key

  - by Luc

  Hello, I am using datamapper in a ruby application and I'm facing a problem I do not understand. I have a Appartment model and a Location model. An appartment is at a given location and several appartments can be at the same location. This typically described a 1-n relationship (I guess :-) ) My feeeling is that in the Appartement sql table I need a location_id but I do not want any Appartment pointers within the Location table. For me, Location should live on its own and should not reference appartment. In the Appartement ruby class, I have added: has n, Location but it then creates an appartment_id within the Location ruby class, which I do not want. Would you have any clue ? Thanks a lot, Luc

• Import AppleScript methods in another AppleScript?

  - by DASKAjA

  Is there a way to use defined AppleScript methods in other AppleScripts which reference the original AppleScript with something similar to import (f.e. in PHP)? I wrote a methode to set Skype status and mood-text: on setSkypeStatus(status, mood_text) tell application "System Events" set skypeRunning to count (every process whose name is "Skype") if skypeRunning > 0 then --only set status if skype is running tell application "Skype" set myStatus to "SET USERSTATUS " & status set myMood to "SET PROFILE MOOD_TEXT " & mood_text send command myStatus script name "AppleScript" send command myMood script name "AppleScript" return skypeRunning end tell else return skypeRunning end if end tell end setSkypeStatus now I'm searching for something like import skype_methods.scpt. Is there such a functionality. I can't something related with Google.

• Equality between two enumerables

  - by Berryl

  I have two enumerables with the exact same reference elements, and wondering why Equals wouldn't be true. As a side question, the code below to compare each element works, but there must be a more elegant way Cheers, Berryl var other = (ActivityService) obj; if (!AllAccounts.Count().Equals(other.AllAccounts.Count())) return false; for (int i = 0; i < AllAccounts.Count(); i++) { if (!AllAccounts.ElementAt(i).Equals(other.AllAccounts.ElementAt(i))) { return false; } } return true;

• Rosetta Stone: Great example projects

  - by Adam Bellaire

  In your opinion, what is a great example application which demonstrates the best techniques for its language and problem domain, and could be used as a reference for other programmers? Please provide answers where the source is readily available for viewing (i.e. open-source projects), and provide a link. The first line of each answer should indicate the language and the problem domain in bold, e.g.: Java - Web Application ... or ... C# - DX Game As with other Rosetta Stone questions, the answers here should demonstrate the language/technology in the example in such a way that programmers who aren't familiar with them can get an impression of what they're like.

• Flex HDividedBox Divider backgroundColor

  - by Jeremy Mitchell

  Is there an easy way to set the backgroundColor of a HDividedBox's (or VDividedBox's) BoxDivider object(s)? A BoxDivider is the "divider" that has the drag handle on it. By default, the BoxDivider is transparent with the little handle image on it. There is a dividerSkin style that defaults to mx.skin.BoxDividerSkin which is a reference to a symbol in the Assets.swf file. Any ideas? Do I have to make an alternate skin? Is that my only option? Googling this led me to many solutions that were weird and hacky and frankly didn't seem to work. Thanks.

• Sharing constants across a WCF service

  - by Sandor Davidhazi

  I have certain strings which contain special characters so they can not be shared as enum members across a WCF service. (Actually, they are keys for configuration values.) I want to be able to pass in the keys at client side and get back the config values. If there is a change, I only want to change the config keys at one place. Constants would be ideal, because they can be changed as strong references across the entire solution, and the underlaying value could be updated with a service reference update. Currently I can think of two possible solutions: Create a shared assembly and place the constants there Share the constants across the service. The problem is, I can't get the datacontractserializer to serialize the constants. Is that possible at all? Is the shared assembly the only option I have?

• How to setup a project to use TweetSharp

  - by Stuart Helwig

  I am trying to follow Pete Brown's introductory WPF tutorial which makes use of the TweetSharp libraries to interact with Twitter. I have downloaded what appears to be the latest TweetSharp binaries (and a few others including the ReleaseCandidate) from Codeplex (http://tweetsharp.codeplex.com/). No matter what references I add and no matter what using statements I try, I cannot create a reference to the TwitterService for the FluentTwitter class. I simply get the compiler error - "The type or namespace cannot be found". Now I've noticed that the TweetSharp.dll that Pete references is 518KB but the one contained in each of my different downloads is only 84kb. (I've tried several times - I am getting the full download here). The link from Pete's article to the TweetSharp libraries, no longer works (http://code.google.com/p/tweetsharp/). What basic element am I missing here or what could I be doing wrong?

• boost's regex won't compile

  - by myeviltacos

  Hi everyone. I am using boost 1.45.0 on Ubuntu with Code::Blocks as my IDE, and I can't get basic_regex.hpp to compile. I'm pretty sure I set up boost correctly, because I can compile programs using boost::format without any errors. But I'm getting this annoying error, and I don't know how to get rid of it.

• (C#) iterate over read-only private collection member

  - by DGH

  I have a class which has two HashSet collections as private members. Other classes in my code would like to be able to iterate over those HashSets and read their contents. I don't want to write a standard getter because another class could still do something like myClass.getHashSet().Clear(); Is there any other way to expose the elements of my HashSets to iteration without exposing the reference to the HashSet itself? I'd love to be able to do this in a way that is compatible with for-each loops.
