  • Interface member name conflicts in ActionScript 3

    - by Aaron
    I am trying to create an ActionScript 3 class that implements two interfaces. The interfaces contain member functions with different signatures but the same name: public interface IFoo { function doStuff(input:int):void; } public interface IBar { function doStuff(input1:String, input2:Number):void; } public class FooBar implements IFoo, IBar { // ??? } In C# this problem can be solved with explicit interface implementations, but as far as I can tell ActionScript does not have that feature. Is there any way to create a class that implements both interfaces?

  • Casting in MVVM Light CommandParameterValue

    - by user275561
    here is my Problem, I want to pass the integer 1 when this canvas is pressed. Every time I click the canvas, I get a An unhandled exception of type 'System.InvalidCastException' occurred in GalaSoft.MvvmLight.dll. Now I could make my life easier and just do the RelayCommand to accept a String instead of int but for the sake of learning. How would i go about doing it this way, <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonDown"> <cmd:EventToCommand Command="{Binding ButtonPress}" CommandParameterValue="1" </i:EventTrigger> </i:Interaction.Triggers>

  • Difference between Setting.settings and web.config?

    - by Muneeb
    This might sound a bit dumb. I always had this impression that web.config should store all settings which are suspect to change post-build and setting.settings should have the one which may change pre-build. but I have seen projects which had like connection string in setting.settings. Connection Strings should always been in web.config, shouldnt it? I am interested in a design perspective answer. Just a bit of background: My current scenario is that I am developing a web application with all the three tiers abstracted in three separate visual studio projects thus every tier has its own .settings and .config file.

  • JodaTime DateFormatter to display milliseconds if nonzero

    - by Mike
    I want to display a list of dates that may or may not have milliseconds on them. If a certain entry has milliseconds, then it should be displayed like yyyy MM dd HH:mm:ss.SSS. If it doesn't have the millis, I need it displayed as yyyy MM dd HH:mm:ss. I suppose the general question is: Is there a way to describe an optional format string parameter? (I'd like to avoid refactoring all of the places that I use formatters since this is a large code base.)

  • SQL Server CE - Internal error: Cannot open the shared memory region

    - by blu
    I have a SQL Server CE database that works fine in dev, but when installed on the client has an issue. The SQL Server CE 3.5 dependencies are copied as part of the deployment. The target machine is a clean Windows 7 32-bit Ultimate image. The message for the exception in the event log is: Internal error: Cannot open the shared memory region. It looks like this is SSCE_M_CANTOPENSHAREDMEMORY and the site says there isn't a connection string value to change this and that these issues are typically not resolvable by the end developers. Has anyone run into this, and if so were you able to resolve this issue?

  • How to set target hosts in Fabric file

    - by ssc
    I want to use Fabric to deploy my web app code to development, staging and production servers. My fabfile: def deploy_2_dev(): deploy('dev') def deploy_2_staging(): deploy('staging') def deploy_2_prod(): deploy('prod') def deploy(server): print 'env.hosts:', env.hosts env.hosts = [server] print 'env.hosts:', env.hosts Sample output: host:folder user$ fab deploy_2_dev env.hosts: [] env.hosts: ['dev'] No hosts found. Please specify (single) host string for connection: When I create a set_hosts() task as shown in the Fabric docs, env.hosts is set properly. However, this is not a viable option, neither is a decorator. Passing hosts on the command line would ultimately result in some kind of shell script that calls the fabfile, I would prefer having one single tool do the job properly. It says in the Fabric docs that 'env.hosts is simply a Python list object'. From my observations, this is simply not true. Can anyone explain what is going on here ? How can I set the host to deploy to ?

  • Why does this call to jQuery's $.ajax() fire an empty request in Chrome and Firefox?

    - by Martin Wiboe
    Hello, I am trying to call a WCF RESTful service from jQuery. I am using JSON to encode both request and response. The following code functions correctly in IE8: url = 'http://ipv4.fiddler:5683/WeatherWCF/NewBinding/MyService/GetValueFloat'; $.ajax({ url: url, data: '{"alias": "Udetemperatur"}', type: "POST", contentType: "application/json; charset=utf-8", dataType: "text", // not "json" we'll parse success: function(res) { alert('Received response: ' + res); } }); However, in both Firefox and Chrome, res contains an empty string. After using Fiddler to monitor the request, it appears that jQuery sends an empty request to the server as shown in this screen dump: http://imgur.com/EJgwS.png This is the successful request: http://imgur.com/S77BA.png What am I doing wrong? Kind regards, Martin

  • How to use @FileUpload.GetHtml inside Html.BeginForm and sumbit FilesList

    - by Diode
    There is a default submit button for the @FileUpload.GetHtml. But I am expecting to have a submit button inside the Html begin form and use that substitution to submit the list of files with some more parameters. But when I do that the passing IEnumerable is always null in the Action method. This is my Action method: [HttpPost] public ActionResult Change(IEnumerable filesList, Guid ID, string Btn) {.... @using (Html.BeginForm("Change", "Home",FormMethod.Post)) { <textarea id="textArea" name="epost2" class="frm_txtfield_big" style="float:left; width:638px; height:200px;"></textarea> <input type="hidden" name="supportID" value="@Model.ID" /> @FileUpload.GetHtml(name: "ChooseFile",initialNumberOfFiles: 1,allowMoreFilesToBeAdded: true,includeFormTag: false) .......} But this is not passing the list of files to the method. Am doing it wrong or what is the wrong with the code.

  • Parse text from a screen grab

    - by Caylem
    Hey guys Not sure the best way to explain this but i'll give it a shot. I'm trying to find a way to parse text/numbers from a screen grab in either C# or Java - whichever provides the easiest way, but preferably java. An example would be as follows. You have a website/document/application with a block of text. You can take a screenshot of the specific area which contains this text. Once the screenshot has been taken you can extract a string from it containing the relevant characters. Any feedback is appreciated. Thanks

  • Get Instance from StructureMap by Type Name

    - by JC Grubbs
    Is there any way to request an instance from the StructureMap ObjectFactory by the string name of the type? For example, it would be nice to do something like this: var thing = ObjectFactory.GetInstance("Thing"); The use case here is a messaging scenario in which the message is very generic and contains only the name of a task. The handler receives the message, gets the task name from the message and retrieves the Type of task runner from a configuration database. StructureMap scans all the assemblies in a directory and one of them will contain the Type returned from the config database which then needs to be instantiated. The other possibility is to grab a Type instance by doing the following: var type = Type.GetType("Thing"); But the problem there is the assembly may or may/not be loaded in the AppDomain so that reflection call isn't always possible.

  • List<T>.SelectMany(), Linq and lambda help

    - by jim
    Hi there I have a class. public class MedicalRequest { private int id private IList<MedicalDays> Days private string MedicalUser ... } and another public class MedicalDays { private int id; private DateTime? day private MedicalRequest request ... } I'm using nhibernate to return a list of all the MedicalDays within a time span. I'd like to do something like this to the resulting list //nhibernate query IList<MedicalDays> days = daysDao.FindAll(searchCritCollection); //select a list of days from resulting list IEnumerable<MedicalDays> queriedList = days.SelectMany(i => i.MedicalRequest.MedicalUser == employee); Linq tells me that the type cannot be inferred by the usage. I'd like to know what I'm doing wrong, and if there is a preferred way of doing something like this. Thanks for your time.

  • Android: How to call call ndk function from AsyncTask?

    - by user1628803
    I have a lot of jni calls in my Android projects which work like a charm but this one I just can't get right: When trying to call a jni function from an AsyncTask in Android I get this error message: 11-30 10:07:20.130: W/dalvikvm(16555): No implementation found for native Lcom/company/MainView$MyAsyncTask;.MyFunction (Ljava/lang/String;)Z When usually the jni function declaration works like this: JNIEXPORT jboolean JNICALL Java_com_company_MainView_myFunction()... how would i declare it when calling from an AscnyTask? I didn't find the answer on Google and I have unsuccessfully tried: JNIEXPORT jboolean JNICALL Java_com_company_MainView$MyAsyncTask_myFunction() and JNIEXPORT jboolean JNICALL Java_com_company_MainView_MyAsyncTask_myFunction() Or is this not possible at all?

  • Membership.GetUser() within TransactionScope throws TransactionAbortedException

    - by Bob Kaufman
    The following code throws a TransactionAbortedException with message "The transaction has aborted": using ( MyDataContext context = new MyDataContext() ) { using ( TransactionScope transactionScope = new TransactionScope() ) { Guid accountID = new Guid( Request.QueryString[ "aid" ] ); Account account = ( from a in context.Accounts where a.UniqueID.Equals( accountID ) select a ).SingleOrDefault(); IQueryable < My_Data_Access_Layer.Login > loginList = from l in context.Logins where l.AccountID == account.AccountID select l; foreach ( My_Data_Access_Layer.Login login in loginList ) { MembershipUser membershipUser = Membership.GetUser( login.UniqueID ); } } } The error occurs at the call to Membership.GetUser(). My Connection String is: <add name="MyConnectionString" connectionString="Data Source=localhost\SQLEXPRESS;Initial Catalog=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" /> Everything I've read tells me that TransactionScope should just get magically applied to the Membership calls. The user exists (I'd expect a null return otherwise.)

  • Searching a large list of words in another large list

    - by Christian
    I have a list of 1,000,000 strings with a maximum length of 256 with protein names. Every string has an associated ID. I have another list of 4,000,000,000 strings with a maximum length of 256 with words out of articles and every word has an ID. I want to find all matches between the list of protein names and the list of words of the articles. Which algorithm should I use? Should I use some prebuild API? It would be good if the algorithm runs on a normal PC without special hardware.

  • sorting and paging with gridview asp.net

    - by dangerisgo
    I'm trying to get a gridview to sort and page manually with no success. The problem is that when a user clicks the column they want to sort, it sorts that page, but doesn't sort the datasource (dataview) behind the gridview. So when they progress to a different page, their sort is lost. Pretty much I'm looking for a sort that will actually sort the datasource behind the gridview. Here is what I have so far: protected void GridView_OnSort(object sender, GridViewSortEventArgs e) { String sortExpression = e.SortExpression; if (GridViewSortDirection == SortDirection.Ascending) { DataView myDataView = new DataView(mybll.GetItemsOrdered()); myDataView.Sort = sortExpression + " DESC"; GridView.DataSource = myDataView; GridView.DataBind(); } else { DataView myDataView = new DataView(mybll.GetItemsOrdered()); myDataView.Sort = sortExpression + " ASC"; GridView.DataSource = myDataView; GridView.DataBind(); } } Any help would be appreciated. Thanks.

  • Session bug using facebook-connect-with-authlogic in Rails

    - by Jesse
    I'm trying to follow this article: http://ryanbigg.com/2010/03/testing-facebook, but I'm stuck. I think the problem is with my session, in that the current_usermethod comes up with nil for session[:facebook_session]. According to the original authlogic, it says to use the active_record_store for sessions: # config/environment.rb config.action_controller.session_store = :active_record_store # db/schema includes create_table "sessions", :force => true do |t| t.string "session_id", :null => false t.text "data" t.datetime "created_at" t.datetime "updated_at" end The article calls for the use of cookies. I'm confused; can I use cookies and the active record sessions? I'm also confused by the use of cattr_accessor :current_user from within the User model -- current_user still goes in the application controller, right? Please help.

  • Defining DateDiff for a calculated column in a datatable

    - by Nir
    I have the column DateTimeExpired, and I would like to create another column called "Expired" which will show "Yes" or "No" according to the expiration date - "Yes" if the date has already passed. I wrote this: DataColumn colExpirationDate = new DataColumn("DateTimeExpired", typeof(DateTime)); DataColumn colExpired = new DataColumn("Expired", typeof(string), "IIF(DateDiff(DateTimeExpired, date())>= 0,'No','Yes')"); But I get an exception "The expression contains undefined function call DateDiff()." (please note that I always want to get the row, no matter if it's expired or not) How do I set the column's text to the correct form?

  • PerformanceCounters on .NET 4.0 & Windows 7

    - by scott
    I have a program that works fine on VS2008 and Vista, but I'm trying it on Windows 7 and VS2010 / .NET Framework 4.0 and it's not working. Ultimately the problem is that System.Diagnostics.PerformanceCounterCategory.GetCategories() (and other PerformanceCounterCategory methods) is not working. I'm getting a System.InvalidOperationException with the message "Cannot load Counter Name data because an invalid index '' was read from the registry." I can reproduce this with the very simple program shown below: class Program { static void Main(string[] args) { foreach (var pc in System.Diagnostics.PerformanceCounterCategory.GetCategories()) { Console.WriteLine(pc.CategoryName); } } } I did make sure I'm running the program as an admin. It doesn't matter if I run it with VS/Debugger attached or not. I don't have another machine with Windows 7 or VS2010 to test it on, so I'm not sure which is complicating things here (or both?). It is Windows 7 x64 and I've tried forcing the app to run in both x32 and x64 but get the same results.

  • Customizing Rails XML rendering to include extra properties

    - by Isaac Cambron
    Let's say I have a model like this: create_table :ninjas do |t| t.string name end And the Ninja class with an extra property: class Ninja < ActiveRecord::Base def honorific "#{name}san" end end And in my controller I just want to render it to XML: def show render :xml => Ninja.find(params[:id]) end The honorific part isn't rendered. That makes sense, since it's just a method, but is there a way of tricking it? I'm totally up for answers to the effect of, "You're doing this totally wrong." I'll just add that I really do want to calculate the honorific on the fly, and not, like, store it in the database or something.

  • What does "?ref=ts" mean in a FACEBOOK APP url

    - by jozecuervo
    When Facebook drives traffic to an app, they often append &ref=whatever to the query string. This is useful for figuring out which integration points are working or not. I've figured out what some of these mean. For example: ref=bookmarks - the user clicked on a bookmark. ref=game_my_recent - the user clicked on the upper portion of the games dashboard. Does anyone know what "ref=ts" means? It accounts for a ton of traffic. I've viewed source on pages all over common FB pages and cannot find a match for ant piece of content generated by any of my apps. Same question, posted by me on the FB DEV FORUM: http://forum.developers.facebook.com/viewtopic.php?id=54866 I'm thinking I'll get better answers here ;) Thanks people, Jose

  • Authenticating with Netflix: Netflix OAuth vs. SignPost OAuth: Which is correct?

    - by Stefan Kendall
    With signpost 1.2: String authUrl = provider.retrieveRequestToken( consumer, callbackUrl ); Netflix API response: <status> <status_code> 400 </status_code> <message> oauth_consumer_key is missing </message> </status> I see how to craft the URL manually via the netflix documentation, but this seems to contradict other services which use OAuth authentication. Who's incorrect, here? Is there a way to get signpost to work with Netflix, aside from contributing to the signpost source? :P
