• AccountModel into a Repository and Interface

  - by Jemes

  I'm trying to separate the default AccountModel in mvc2 into a separate interface and repository. I've created an Interface and Repository and copied over the code from the AccountModel. I can register users and create accounts but in Visual Studio I'm getting the error below on the AccountController (* below). Error 1 Inconsistent accessibility: parameter type 'Admin.Models.IMembershipService' is less accessible than method 'Admin.Controllers.AccountController.AccountController(Admin.Models.IMembershipService) public class AccountController : Controller { private IMembershipService MembershipService; public AccountController() : this(new dao_MembershipService()) { } public **AccountController**(IMembershipService repository) { MembershipService = repository; } Does anyone know how I could fix the error?

• Pass var to jquery from div

  - by user1518202

  I am using a jquery function to open a dialog box, and I need to be able to change the height and the width of the box. I am wanting to pass it a parameter from within the DIV. I have looked at many different possibilities, but to no avail. Any ideas would be greatly appreciated. $.fx.speeds._default = 1000; $(function() { $("#dialog").dialog({ autoOpen: false, height: 300, width: 500, show: "drop", hide: "drop" }); $("#opener").click(function() { $("#dialog").dialog("open"); return false; }); }); Here is my Div. <div id="dialog"> Some text here </div>

• FLEX, Actionscript: how can I invoke a CustomEvent ?

  - by Patrick

  hi, I've created a custom MouseEvent in Flex: package { import flash.events.MouseEvent; public class CustomMouseEvent extends MouseEvent { public var tags:Array = new Array(); public function CustomMouseEvent(type:String, tags:Array) { super(type, true); this.tags = tags; } } } Now I would like to understand how to pass the parameter tags from both Actionscript and MXML: From actionscript I'm trying something like this, but it doesn't work: newTag.addEventListener(MouseEvent.MOUSE_UP, dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP,[newTag.name]))); From MXML i'm doing this and it doesn't work as well: <mx:LinkButton click="dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP, bookmarksRepeater.currentItem.tags))" /> thanks

• Jquery adding events

  - by JBone

  I want to add an event handler to some dynamically added elements. I simplified my problem into the basic code below. I am using the new JQuery 1.7 on feature to say "hey for all labels in the CancelSurvey id element call this notify function when they are clicked." function notify(event) { console.log(event.data.name); } $('#CancelSurvey').on('click', 'label', { name: $(this).attr("id") }, notify); I want to pass the id of the label as parameter "name". When I try to alert this it is undefined (they are defined in the html created). I believe that using the $(this) is not referencing the label selector in this case. It actually seems to be referencing the document itself. Any ideas on how to accomplish this?

• Translate sequence in macro parameters to separate macros

  - by Alex Tiger

  How to acces each element in macro if the definition is like MACRO(name, seq) and the code is like: MACRO("TheName", (Elem1) (Elem2) (Elem3) ) I want to generate the next code: MACRO("TheName", ELEMMACRO(Elem1) ELEMMACRO(Elem2) ELEMMACRO(Elem3) ) Or something like that. In other words, I want to process every parameter separately (I don't care of definition, even if it will be something like MACRO("TheName", Elem1, Elem2, Elem3 ) There could be more elements, there could be less. I have tried V_ARGS (I need it only for gcc), but I can only copy all the elements by that, not to process them separately. What can I do? P.S. Because of some reasons, I can't use Boost.

• How to strip debug code during compile time in C++?

  - by juvenis

  Say I have a C++ function debugPrint(int foo). How can I most conveniently strip that from release builds? I do not want to surround every call to debugPrint with #ifdefs as it would be really time consuming. On the other hand, I want to be 100% sure that the compiler strips all the calls to that function, and the function itself from release builds. The stripping should happen also, if it's called with a parameter that results from a function call. E.g., debugPrint(getFoo());. In that case I want also the getFoo() call to be stripped. I understand that function inlining could be an option, but inlining is not guaranteed to be supported.

• what's the job of std::unique_lock when used with std::conditional_variable::wait()

  - by Mike

  I'm quite confused with the need of a std::unique_lock when wait a std::conditional_variable. So I look into the library code in VS 2013 and get more confused. This is how std::conditional_variable::wait() implemented: void wait(unique_lock<mutex>& _Lck) { // wait for signal _Cnd_waitX(&_Cnd, &_Lck.mutex()->_Mtx); } Is this some kind of joke? Wrap a mutex in a unique_lock and do nothing but get it back latter? Why not just use mutex in the parameter list?

• URL getRequestParameterMap not working

  - by DD

  I'm using IceFaces 1.8.2 and trying to get a parameter from the URL using: ((HttpServletRequest) FacesContext.getCurrentInstance() .getExternalContext().getRequest()).getParameter(name); This works fine on the inital request. However, when I do a partialSubmit on a component, it stops working. I'm assuming that its to do with how requests are processed when partial submits are done. Is there a workaround? At the moment, I'm having to ((HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext() .getRequest()).getQueryString(); and manually pass the query string. Thanks.

• ASP.NET MVC - Custom object instantiation / providing with the Modelbinder?

  - by ropstah

  Is it possible to customize the object initiation / providing with the default ASP.NET MVC Modelbinder? <AcceptVerbs(HttpVerbs.Post)> _ Function EditObject(id As int, <Bind(Exclude:="Id")> obj As BLL.Object) As ActionResult End Function I would like to 'provide' obj to the modelbinder. (i don't want the Modelbinder to use New() and instantiate obj, but I want to deliver the object from a custom repository.) Is this possible? Edit: The loading from the repository should be done based on the id parameter of EditObject...

• What is the point of Convert.ToDateTime(bool)?

  - by Paul Alan Taylor

  I was doing some type conversion routines last night for a system I am working on. One of the conversions involves turning string values into their DateTime equivalents. While doing this, I noticed that the Convert.ToDateTime() method had an overload which accepted a boolean parameter. First question? Under what circumstances could this ever be useful? I went a little further and tried to execute the method in QuickWatch. Either way ( true or false ), the routine returns an InvalidCastException. Second question? Why is this method even here?

• Solution to compiler warning for generic varargs

  - by TJR

  A puzzle from this blog. Similar to SO1445233. Given the following source listing, explain why the compiler is producing a warning at invocation to the list method and give a solution for removing the warning without resorting to @SuppressWarnings annotation. public class JavaLanguagePuzzle3 { public static void main(String[] args) { list("1", 2, new BigDecimal("3.5")); } private static <T> List<T> list(T... items) { return Arrays.asList(items); } } Warning: Type safety: A generic array of Object&Serializable&Comparable<?> is created for a varargs parameter

• Bitwise setting in C++

  - by Sunil

  enum AccessSource { AccessSourceNull = 0x00000001, AccessSourceSec = 0x00000002, AccessSourceIpo = 0x00000004, AccessSourceSSA = 0x00000008, AccessSourceUpgrade = 0x00000010, AccessSourceDelta = 0x00000020, AccessSourcePhoneM = 0x00000040, AccessSourceSoft = 0x00000080, AccessSourceCR = 0x00000100, AccessSourceA = 0x00000200, AccessSourceE = 0x00000400, AccessSourceAll = 0xFFFFFFFF }; What is the value of AccessSourceAll ?? is it -1? or is it maximum value? I have a parameter ULONG x , whose default value is AccessSourceAll(that means access to all). How do i remove the access right of AccessSourceE only? How to add the access right of AccessSourceE again? If i have a particular value in x, then how do i know whether AccessSourceE is set or not?

• How can I convert my Stream (image data) back into a file

  - by James Hay

  I have a WCF restful service that I'm trying to upload an image to. I have a very basic metod that accepts a stream as it's only parameter and is defined in the contract as: [OperationContract] [WebInvoke(UriTemplate = "ReviewImage", BodyStyle = WebMessageBodyStyle.Bare, Method = "POST")] ReviewImage UploadImage(Stream data); I'm actually consuming this service from flash (which is fairly inconsequntial) which selects a file from the file system and uploads it through the service url. It all works seems to work, adding a breakpoint to the UploadImage method breaks as expected. If I wanted to save this file back to disk, is it just a case of reading this Stream object into a FileStream object that creates the file somewhere? A bit like the this? When i do actually do this the file can not be opened as an image. I'm sure i'm missing a key piece of knowledge here. Does my stream actually contain just the image bytes or does it contain more than that?

• Create macro to move data in a column UP?

  - by user1786695

  I have an excel sheet of which the data was jumbled: for example, the data that should have been in Columns AB and AC were instead in Columns B and C, but on the row after. I have the following written which moved the data from B and C to AB and AC respectively: Dim rCell As Range Dim rRng As Range Set rRng = Sheet1.Range("A:A") i = 1 lastRow = ActiveSheet.Cells(Rows.Count, "A").End(xlUp).Row For Each rCell In rRng.Cells If rCell.Value = "" Then Range("AB" & i) = rCell.Offset(0, 1).Value rCell.Offset(0, 1).ClearContents End If i = i + 1 If i = lastRow + 1 Then Exit Sub End If Next rCell End Sub However, it doesn't fix the problem of the data being on the row BELOW the appropriate row now that they are in the right columns. I am new to VBA Macros so I would appreciate any help to make the data now align. I tried toggling the Offset parameter (-1,0) but it's not working.

• Are booleans as method arguments unacceptable?

  - by koschi

  A colleague of mine states that booleans as method arguments are not acceptable. They shall be replaced by enumerations. At first I did not see any benefit, but he gave me an example. What's easier to understand? file.writeData( data, true ); Or enum WriteMode { Append, Overwrite }; file.writeData( data, Append ); Now I got it! ;-) This is definitely an example where an enumeration as second parameter makes the code much more readable. So, what's your opinion on this topic?

• Hitting a Button -> Executing any class function I give it in the parameters (C++)

  - by Barnes Noble

  Can anyone help me with class function parameter callbacks? I'm not so sure how to set it up in my code here: http://codepad.org/fvwHtDjQ Basically I've got a player and an enemy. I have two buttons. One button when clicked should let the player jump. The other should make the enemy hit something. When clicked, each button has to correspond to the class function in the parameters. I'm not sure how to set it up though.

• Get result type of function

  - by Robert

  I want to specialize a template function declared as: template<typename Type> Type read(std::istream& is); I then have a lot of static implementations static int read_integer(std::istream& is); a.s.o. Now I'd like to do a macro so that specialization of read is as simple as: SPECIALIZE_READ(read_integer) So I figured I'd go the boost::function_traits way and declare SPECIALIZE_READ as: #define SPECIALIZE_READ(read_function) \ template<> boost::function_traits<read_function>::result_type read(std::istream& is) { \ return read_function(is); \ } but VC++ (2008) compiler complains with: 'boost::function_traits' : 'read_integer' is not a valid template type argument for parameter 'Function' Ideas ?

• C# - Silverlight - Custom control or UserControl ?

  - by cmaduro

  I need a button that is visually completely customizable, but has custom logic to publish events and manage it's visual state based on events it has registered for. When I say visually customizable, I mean I should be able to both create the button in xaml and set it's style by binding to the supplied style. Or I can create an instance of the button and set the style by passing a parameter to an alternate constructor. Or by calling a method on the button class to set the style. I do not plan on substituting the controls template, it should be a button. Can anyone point me to some code samples of this?

• Play Framework Form "fold" method naming rationale

  - by oym

  Play Framework's (2.x) Form class has a method called fold who's usage is indicated as: anyForm.bindFromRequest().fold( f => redisplayForm(f), t => handleValidFormSubmission(t) ) Essentially, the first function parameter is what gets executed on binding failure, and the 2nd on binding success. To me it seems similar to the 'success' and 'error' callbacks of jquery's ajax function. My question is why did the Play developers call the method "fold"? As a disclaimer I am new to Scala, but I am failing to see the connection between this and the functional Scala fold operation. The only similarity is that it is a higher order function; but I don't see any combining that is taking place, nor does it delegate internally in its implementation to any of the Scala fold functions.

• ASP.NET 3.5: GetCallbackEventReference doesn't work synchronously

  - by deadbug

  I have an ASP.NET 3.5 WebForm that leverages the frameworks Page.ClientScript.GetCallbackEventReference() method and I'd like some of the calls to be synchronous. Now, the documentation says that the 5th parameter (see below) controls this. Specifically, when you pass 'false' it's supposed to be a non-asynchronous call. However, regardless if it's true or false, it still processes the call asynchronously. Page.ClientScript.GetCallbackEventReference(this, "arg", "ReceiveServerData", "context",false); Is there a work-around for this or perhaps I'm doing something wrong? Thanks in advance for the assistance!

• How can I "undelete" a set of documents in CouchDB?

  - by radicand

  I have a large set of documents in a CouchDB database that were just accidentally bulk deleted using _deleted:true. I also have a backup for this set of data that includes their last known good revision and metadata. I need to maintain the same _id, so simple restore with a new _id is not an option. Compaction has not been run and I can access any of these documents via the &rev= url parameter as well as their attachments (which are needed). What I need to do is "restore" these documents to the revision I have on file. Surprisingly, I have come up empty with any queries on how to achieve this. Tips or hacks appreciated.

• rails - REST or create another method

  - by user1304740

  Let's assume we have two models linked with a 1-to-many relationship (like clients and invoices - a client can have many invoices). In a view of a 'client' (let's say the 'show' view), there is a form to capture an 'invoice'. I found 2 approaches: This form should be handled by the 'invoice' controller (method create), having client_id passed as a parameter This form should be handled by a new method in 'client' controller, probably a PUT method defined in routes.rb. Is there a 'Rails way', or both of them are good? Is there a preffered way? Thanks!

• Java Programming Help

  - by user215049

  hi, im a bit confused on this and i dont know how to solve this question that i have been asked, id be grateful if you could assist me on this question, maybe try to tell me what needs to be done, and how. the question is: Write a method called countChars which takes an InputStream as a parameter, reads the stream and returns the number of characters it contains as an int. Any IOExceptions which might occur in the method should be passed back to the method's caller. Note that the method header should show that it is possible that an exception might occur. i attempted this question with the following code: public class countChars { public int countChars(int InputStream) { return InputStream; } } and i get an error message saying : Main.java:26: cannot find symbol symbol : method countChars(java.io.InputStream) location: class Main s1 = "" + countChars(f1); ^ 1 error
