  • PHP MVC correct usage

    - by Ratt
    What is the correct (recommended method) for passing information to a view in a MVC environment. Currently we use Zend Framework, where we write classes to handle specific things EG a Book class with a save and load method to retrieve info from the DB, which is called from a particular nameAction(). What I would like to know is what is the best way to pass this information to the view, in some cases we do $this-view-book_name = $book-getBookName(); and in other cases we do the following $this-view-book = $book; OR $this-view-books = Book_Manager::getAllBooks(); and then access the object(s) properties in the view. Information on-line suggests we try limit what access a view has to information, i.e pass them only what they need and in some cases people say its ok to pass stuff through as long as nothing is done to that information.

  • How should I re-raise a Delphi exception after logging it?

    - by Nik
    Do you know a way to trap, log, and re-raise exception in Delphi code? A simple example: procedure TForm3.Button1Click(Sender: TObject); begin try raise Exception.Create('Bum'); except on E: Exception do begin MyHandleException(E); end; end; end; procedure TForm3.MyHandleException(AException: Exception); begin ShowMessage(AException.Message); LogThis(AException.Message); // raise AException; - this will access violate end; So I need to re-raise it in the except block but I was wondering if there is a better way to write my own method to handle and (on specific conditions) to re-raise exceptions.

  • How do I visualize a complex graph in .Net?

    - by Ivan
    I need to visualize a graph (technically being a set of Entity Framework objects, but I can translate it to another representation if needed) of this kind. I don't know how to name it (by the way, if you know - I'll appreciate if you tell me). It would be ideal for graph elements to be clickable (so that when user clicks on a block, I can handle an event with the element id specified) but I can survive even without any interactivity. Are there any components available good for this task? If no, what should I look for to help me to develop an algorithm for drawing such a graph with visually-comfortable layout?

  • Scrum metrics for quality

    - by zachary
    What is the best way to measure QA in scrum? We have members who typically test and they are measured against how many bugs they find. If they don't find any bugs then they are considered to be doing a bad job. However, it is my understanding that the developers and quality people are considered one in the same. I would think that they should be judged against the same metrics... not different metrics then the developers who may also be doing testing work... What is the best way to handle metrics for QA and should QA people have separate metrics from developers in scrum? Any documents or links someone can point me to in regards to this?

  • Explicitly multiplying values as longs

    - by Bill Szerdy
    I understand that all math is done as the largest data type required to handle the current values but when you transverse a loop how do you explicitly multiply longs? The following code returns 0, I suspect, because of an overflow. long result = 0L; List<Long> temp = (List<Long>) getListOfIntegers(); for (int i = 0; i < temp.size(); i++) { result *= temp.get(i).longValue(); } System.out.println(result);

  • Concerns with SoapUI Pro when Updating Web Services

    - by Plenoge
    This may unfortunately be a very open-ended question, but a coworker of mine has shared concerns about using SoapUI Pro as our automated regression testing tool primarily on the basis that seemingly trivial WSDL changes can cause headaches for the QA crew. My coworker's particularly concerned that if we update the WSDL, even with a name change, we'll need to touch and update each existing test. As I understand it SoapUI Pro offers a refactoring tool to handle this for you. What are your experiences with SoapUI Pro and updating your web services? Am I missing something?

  • Using Web Flow 2 in JSF application

    - by Tesnep
    Hi, I created a JSF cart application which runs just fine. I am using 'redirect' to fix the problem with refresh. The problem is when there is multiple page flow logic like if you haven't signed up you need to sign up or create an account, and once you do that you need to be redirected back to where you were when you were asked to sign up in the first place. So my goal is to use Web Flow 2 in order to make navigation rules easier to code. I have been working on them separately but I don't know how to merge so that Web Flow can handle navigation instead. Any help is very much appreciated. Thanks.

  • Iterating 'Active' View Controllers

    - by ISDi
    Ola Folks, In an iPhone application I am displaying different views by using the addSubView:SomeViewController.view method. I want to be able to, at the very least, log the view controllers that are in the view hierarchy that is being displayed. I would prefer to be able to get a handle to a specific view controller. I know how to iterate the views, I just do not see how to access the view controllers of those views. I am looking for something that will give me the type of access to the view controllers that UINavigationController::ViewControllers does. I thought I could get away with: for (UIViewController* oVC in [self.view subviews]) but this is not having the intended effect. If someone has a way of doing this, please share it with me. -isdi-

  • [grails] attaching multiple files to a domain class

    - by Emyr
    I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

  • Can someone exaplain me implicit parameters in Scala?

    - by Oscar Reyes
    And more specifically how does the BigInt works for convert int to BigInt? In the source code it reads: ... implicit def int2bigInt(i: Int): BigInt = apply(i) ... How is this code invoked? I can understand how this other sample: "Date literals" works. In. val christmas = 24 Dec 2010 Defined by: implicit def dateLiterals(date: Int) = new { import java.util.Date def Dec(year: Int) = new Date(year, 11, date) } When int get's passed the message Dec with an int as parameter, the system looks for another method that can handle the request, in this case Dec(year:Int) Q1. Am I right in my understanding of Date literals? Q2. How does it apply to BigInt? Thanks

  • creating an options menu with quit application function

    - by Domen Tomažin
    Hello, I'm writing an application for android and I would like to insert an options menu, that would have only one function and that is to quit an application. My options_menu.xml looks like this (I created a new folder under res called menu - just like the instructions said): Than I added the following code to my java class file: @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.options_menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.quit: finish(); return true; default: return super.onOptionsItemSelected(item); } I also defined the @string/quit in values - strings.xml file, but it still says that there is an error: C:\Users\Domen\workspace\Lovne Dobe1.1\res\menu\options_menu.xml:3: error: Error: No resource found that matches the given name (at 'title' with value '@string/quit') So if anybody can help I would be very grateful.

  • Is there any program that obfuscates C# source code?

    - by markattwood
    Our requirement is being able to integrate our DLLs with ClickOnce. Dotfuscator does the obfuscation job nicely but the obfuscated DLLs cannot be deployed with ClickOnce on customer side. On our side, we can handle it perfectly. Moreover, the obfuscated assemblies sometime crashes our .NET CF app. It turns out to a solution that creates a temporary source and obfuscates it before compiling with VS. This ensures that the compiled assembly can be integrated with ClickOnce and fully compatible with .NET CF. What is the best tool to obfuscate C# SOURCE CODE (not assemblies)?

  • Paperclip - Validate File Type but not Presence

    - by Lowgain
    I am using paperclip to handle my file uploads, and in one situation I don't want the file to be mandatory. I do however want to make sure it is a specific file type when it is present. I have this: class TestModel < ActiveRecord::Base #stuff has_attached_file :sound #etc... validates_attachment_content_type :sound, :content_type => ['audio/mp3', 'application/x-mp3'] end And when I have no sound file present, it tells me it is not one of the valid content types. I've tried adding '' to the :content_type array, which also doesn't work! I also attempted creating a lambda procedure for the :if property, but I can't get it to run without some kind of error. Anything missing here?

  • When does ref($variable) return 'IO'?

    - by Zaid
    Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO'. Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to explain why: It isn't possible to create a true reference to an IO handle (filehandle or dirhandle) using the backslash operator. The most you can get is a reference to a typeglob, which is actually a complete symbol table entry [...] However, you can still use type globs and globrefs as though they were IO handles. In what circumstances would ref return 'IO' then?

  • Not compile code blocks when publishing?

    - by Menno Gouw
    I have many lines i just use for debugging and helpers. Is there a way i can mark these so they do not compile when publishing a project but still can use when running/debugging my program within Eclipse? Even better would be to mark a certain field as debug only and discard everything that has to do with that field completely when publishing. I understand this might get one in trouble when using fields like that and using that in critical parts of the code. But i often find myself initializing a lot of debug fields then comment them out which results in errors down the line if i do not comment those out as well. So is there some way to handle this in a better and more efficient way?

  • C# - Sending keyboard events to (last) selected window

    - by Mil
    Hi guys, I want to use virtual keyboard assembly found here http://www.codeproject.com/KB/miscctrl/touchscreenkeyboard.aspx like on screen keyboard (OSK.exe) in Windows. Can someone please tell me how can I use it so that it always stays on top and yet for user to be able to select other windows on dekstop for keyboard input, just like "on screen keyboard" in Windows, specifically I don't know how to select last selected window (can't use GetForegroundWindow or GetFocus only, because when user clicks on virtual keyboard it gets focused and I get handle of keyboard window itself)? This is very urgent to me so any advice would be greatly appreciated. Thanks in advance.

  • ShowDialog returns immediately after a handled exception in .net compact framework

    - by leiz
    The problem I am having is that for some reason ShowDialog returns immediately after handle an exception. However, it works for MessageBox.Show() or at the second time I call ShowDialog. What is the best workaround for this problem? I was only able to find this. And I cannot believe that no one else has this issue. I am using .net compact framework 3.5. Sample code: try { using(SomeForm f = new SomeForm()) { f.ShowDialog(); } } catch(SomeException) { using(SomeOtherForm f = new SomeOtherForm()) { f.ShowDialog(); // this returns immediately // if this is MessageBox.Show(), it works correctly. f.ShowDialog(); // then this works fine } }

  • xajax and codeigniter - blank page and xajax request URI error.

    - by Adam Leonard
    I am unfortunately getting a blank page when trying to run a site locally. There are other people running it locally just fine, so I am wondering if it could be something to do with my LAMP environment. When I attempt to load the site, it's nothing but a blank page. I've ran php index.php in console and the error I get is the following "xajax Error: xajax failed to automatically identify your Request URI.Please set the Request URI explicitly when you instantiate the xajax object.". I'm not quite sure how to handle this in CodeIgniter and or at all to be honest.

  • Invoices for Printing in MS-Access

    - by Nitrodist
    The application that I'm currently working on has a funky set up for the invoices that they print. The form is the invoice that is printed out. I took a look at the Northwind DB and what it does is and it actually generates a report based on the record's information. What are the limitations of using Forms vs. Reports for printing out reports? One of the limitations that I've run into so far is that the printed page is jam packed with information (all required) to fit on a single page, yet there is lots of wasted space for some stuff since elements on the page don't shrink or grow due to what's inputted into the textboxes. How are invoices designed for your applications? How do you handle space restraints for creating invoices?

  • An Actor "queue" ?

    - by synic
    In Java, to write a library that makes requests to a server, I usually implement some sort of dispatcher (not unlike the one found here in the Twitter4J library: http://github.com/yusuke/twitter4j/blob/master/twitter4j-core/src/main/java/twitter4j/internal/async/DispatcherImpl.java) to limit the number of connections, to perform asynchronous tasks, etc. The idea is that N number of threads are created. A "Task" is queued and all threads are notified, and one of the threads, when it's ready, will pop an item from the queue, do the work, and then return to a waiting state. If all the threads are busy working on a Task, then the Task is just queued, and the next available thread will take it. This keeps the max number of connections to N, and allows at most N Tasks to be operating at the same time. I'm wondering what kind of system I can create with Actors that will accomplish the same thing? Is there a way to have N number of Actors, and when a new message is ready, pass it off to an Actor to handle it - and if all Actors are busy, just queue the message?

  • Using Sessions in WCF Services called from Silverlight

    - by Torbjörn Josefsson
    (Using Visual Studio 2008, and Silverlight 3) -I've really looked around for this one, and now I'm just confused by all the solutions that simply won't work for me. I'm trying to call a WCF service from a Silverlight client, which is no problem, but I can't get the service to handle sessions (I want to remember a few things about the callee between calls) I've gathered that basicHttpBinding is no good for sessions, and I haven't managed to make wsHttpBinding work... what's the matter? I would have thought this was a pretty basic thing people would want in their WCF services, or am I just completely muddle-headed not to see how it can be done?

  • SendMessage (F4) fails when sending it to window

    - by Olli
    Working with Visual Studio 6 (VC++ 6.0) I'm using an ActiveX datepicker control which I fail to show expanded by default (3006216). Alternatively I'm trying to send a keyboard message (F4) to my window to open up the control, but nothing happens when I do so... // try 1: use the standard window handle LRESULT result = ::SendMessage(m_hWnd,VK_F4, 0, 0); // try 2: use just use the SendMessage result = SendMessage(VK_F4); result is always 0 - what can I do to test/verify the message sending? Thanks in acvance a lot... Olli

  • Can getters and setters be inlined when definition and declaration are seperated in .h and .cpp files?

    - by Nathan
    I have searched and have been unable to verify how the GCC compiler will handle inlining getters and setters when declaration is in .h file and definition is in .cpp file. Most seem to say that GCC can't see across these source file barriers and won't be able to inline these at all, while others disagree. I have looked at the documentation and I can't find the answer there either. Did I miss it? I do realize that inlining is a choice made by the compiler and is not always guaranteed, but assuming optimal situations, is it at least possible?

  • How do polymorphic inline caches work with mutable types?

    - by kingkilr
    A polymorphic inline cache works by caching the actual method by the type of the object, in order to avoid the expensive lookup procedures (usually a hashtable lookup). How does one handle the type comparison if the type objects are mutable (i.e. the method might be monkey patched into something different at run time). The one idea I've come up with would be a "class counter" that gets incremented each time a method is adjusted, however this seems like it would be exceptionally expensive in a heavily monkey patched environ since it would kill all the PICs for that class, even if the methods for them weren't altered. I'm sure there must be a good solution to this, as this issue is directly applicable to Javascript and AFAIK all 3 of the big JS VMs have PICs (wow acronym ahoy).
