• How can I modify objects inside frames with AS3 in a permanent way?

  - by curro

  I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

• Haskell Syntax: Parse Error On Input

  - by NuNu

  As part of a mini-haskell compiler that I'm writing, I have a function named app. What I want this function to do is take in these arguments epp (App e1 e2). The first step would be to evaluate e1 recursively (epp e1) and check if the output would be an error. If not then evaluate e2 and then call another function eppVals to evaluate the outputs of the calls on e1 and e2 which I defined as v1 and v2 respectively. epp (App e1 e2) | epp e1 /= Error = eppVals v1 v2 | otherwise = Error where v1 = epp e1 v2 = epp e2 <- parse error on input `=' Logically I believe what I have written so far works but I'm getting a parse error on input = where I stated above. Any idea why? My second try epp :: Exp -> Error Val epp (App e1 e2) = (eppVals v1 v2) where v1 = (epp e1) v2 = (epp e2) But now throws Couldn't match expected type Val with actual type Error Val

  - by JG Estevez

  I have a website running over Yii Framework, I created a folder in the root path named blog, I installed a wordpress blog under this folder, but the files .htaccess that comes with yii is trying to redirect my request to www.domain.com/blog to the controller/action type which I don't want, I want to treat the blog folder as a completely app with no relation to yii. here is what I've done so far Options +FollowSymLinks IndexIgnore */* RewriteEngine on RewriteCond %{REQUEST_URI} "/blog/" RewriteRule (.*) $1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . index.php as you can see I added the conditions to avoid redirecting for the blog folder but when I try to access the the url is telling me The page isn't redirecting properly.

• MS Sql Full-text search vs. LIKE expression

  - by Marks

  Hi. I'm currently looking for a way to search a big database (500MB - 10GB or more on 10 tables) with a lot of different fields(nvarchars and bigints). Many of the fields, that should be searched are not in the same table. An example: A search for '5124 Peter' should return all items, that ... have an ID with 5124 in it, have 'Peter' in the title or description have item type id with 5124 in it created by a user named 'peter' or a user whose id has 5124 in it created by a user with '5124' or 'peter' in his street address. How should i do the search? I read that the full-text search of MS-Sql is a lot more performant than a query with the LIKE keyword and i think the syntax is more clear, but i think it cant search on bigint(id) values and i read it has performance problems with indexing and therefore slows down inserts to the DB. In my project there will be more inserting than reading, so this could be a matter. Thanks in advance, Marks

• Slickgrid, confirm before edit

  - by Evan

  I am making a slick grid and need the ability to add rows with a code column. For this to be possible the code column needs to be editable for the entire table. I am trying to work out a way that I can confirm the edit with a standard javascript confirm popup box. I tried putting one into the onedit event within the slickgrid constructor and that executed after the edit. I am led to believe that the edit function is independent from calling the edit stored procedure of the database. Is there a better way to go about this? RF_tagsTable = new IndustrialSlickGrid( LadlesContainerSG , { URL: Global.DALServiceURL + "CallProcedure" , DatabaseParameters: { Procedure: "dbo.TableRF_tags" , ConnectionStringName: Global.ConnectionStringNames.LadleTracker } , Title: "RF tags" , Attributes: { AllowDelete: true , defaultColumnWidth: 120 , editable: true , enableAddRow: true , enableCellNavigation: true , enableColumnReorder: false , rowHeight: 25 , autoHeight: true , autoEdit: false , forceFitColumns: true } , Events: { onRowEdited : rowEdited /*function(){ //this is my failed attempt var r=confirm("Edit an existing tag?") if (r){ alert(r); } else { alert(r); } }*/ , onRowAdded : rowAdded } });

• Size and position of the C# form.

  - by Vytas999

  I use Visual Studio .NET to create a Windows-based application. The application includes a form named CForm. CForm contains 15 controls that enable users to set basic configuration options for the application. I design these controls to dynamically adjust when users resize CForm. The controls automatically update their size and position on the form as the form is resized. The initial size of the form should be 650 x 700 pixels. If CForm is resized to be smaller then 500 x 600 pixels, the controls will not be displayed correctly. How I must ensure that users cannot resize CForm to be smaller than 500 x 600 pixels..?

• jQuery Set Child CSS Attribute Problem

  - by Jascha

  I have a child element of a div named "bob" that's class is '.divTitle' <div id="bob"> <div class="divTitle"> <a href="#"> <h1>Title</h1> </a> </div> </div> I am trying to set the background color of "divTitle" to red but for the life of me can't get this to work. Right now I am trying two things... $('#bob').children('.divTitle')[0].css('background-color', '#0f0'); // assuming children is returning an array... and $('#bob').children('.divTitle').css('background-color', '#0f0'); neither with any success... can anyone tell me what I am missing here? Do I have to go deeper than ".children"?

• Django how to handle # in variable name.

  - by Jack

  I've got a dictionary in python which is assigned as a template variable. One of the keys is named "#text" but when i try to access it using {{ artist.image.3."#text"}} I get an error which is File "/home/jack/Desktop/test/appengine/lib/django/django/template/__init__.py", line 558, in __init__ raise TemplateSyntaxError, "Could not parse the remainder: %s" % token[upto:] TemplateSyntaxError: Could not parse the remainder: "#text" So how can I use this in the template? I've tried putting quotes around it but to no avail. I'd like to not modify the dictionary if possible, but if its easy enough to do then I guess its okay. Thanks

• Why is e.Item.DataItem null on ItemDataBound event when binding an asp:net Repeater to a Collection?

  - by Clean

  Hi, I'm trying to bind a collection implementing the ICollection, IEnumerable and IList interface to an asp.net repeater. The Collection is named CustomCollection. So I'm setting the datasource of the repeater to the collection, as follows: rptRepeater.DataSource = customCollection; rptRepeater.Databind(); Then, on the ItemDataBound event, I'm trying to access the DataItem object, as follow: void rptRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e){ object obj = e.Item.DataItem; // DataItem is null for some reason } For some reason the e.Item.DataItem object is null. Do anyone know why this is, and/or what I could do to get hold of the object in the collection that is to be databound to the repeater? Thanx!

• how to detect an escape sequence in a string

  - by mix

  Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r? What I've tried is: if repr(line).startswith('\r'): blah... but it doesn't catch it. I also tried find, such as: if repr(line).find('\r') != -1: blah doesn't work either. What am I missing? thx! EDIT: thanks for all the replies and the corrections re terminolgy and sorry for the confusion. OK, if i do this print repr(line) then what it prints is: '\rSET ENABLE ACK\n' (including the single quotes). i have tried all the suggestions, including: line.startswith(r'\r') line.startswith('\\r') each of which returns False. also tried: line.find(r'\r') line.find('\\r') each of which returns -1

• What is the result of X(X,X)? [closed]

  - by Sorush Rabiee

  A friend who studies pure mathematics ask me to think about the following problem. Suppose that there is an algorithm named X that has 2 inputs: A and a_1...a_n, where 'A' stands for an arbitary algorithm and 'a_1..a_n' are inputs of A. X receives A and its inputs and returns true if A with a_1..a_n could be terminated, and false if A with a_1..a_n inputs fall into an infinite loop (never ends). Like this: A(n): while(n<5): write "I'm immortal!" and the result of X(A,6) is true and X(A,2) is false. So what is the result of X(X,X)? Also, do you know who was the first to introduce this problem?

• Function matching in Qt

  - by Alexander

  Hello, I have some trouble with Qt. I have a class 'Core' class Core { public: static QString get_file_content(QString filename); static void setMainwindow(MainWindow *w); private: static MainWindow *main_window; }; and class 'MainWindow' in namespace Ui: namespace Ui { class MainWindow; } class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); ~MainWindow(); private: Ui::MainWindow *ui; }; In MainWindow constructor I make MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); Core::setMainwindow(this); } and gets error mainwindow.cpp:8: error: no matching function for call to 'Core::setMainwindow(MainWindow* const)' Of cource, i include core.h with declaration of 'Core' class. That's occurs only on setMainwindow method. So the questions is - why Core class method setMainwindow() is invisible in MainWindow class?

• Flash Hates Me. Error #1009: Cannot access a property or method of a null object reference

  - by sol

  I simply create a movie clip, put it on the stage and give it an instance name of char. Here's my document class, simple as can be: public class Test extends MovieClip { public function Test() { char.x = 1315; char.y = 459; addEventListener(Event.ENTER_FRAME, mouseListen); } private function mouseListen(e:Event) { char.x = mouseX; char.y = mouseY; } } And I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.me::Test/::mouseListen() How in the world is it possible that it knows what "char" is in the constructor but not in the mouseListen function? What else could it be?

• Undefined Variable in Matlab

• JSF hiding exceptions?

  - by bshacklett

  I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

• Default type-parametrized function literal class parameter

• XSLT: How do I trigger a template when there is no input file?

  - by Ben Blank

  I'm creating a template which produces output based on a single string, passed via parameter, and does not use an input XML document. xsltproc seems to happily run with a single parameter specifying the stylesheet, but I don't see a way to trigger a template without an input file (no parameter to xsltproc to run a named template, for example). I'd like to be able to run: xsltproc --stringparam bar baz foo.xsl But I'm currently having to run, with the "main" template matching "/": echo '<xml/>' | xsltproc --stringparam bar baz foo.xsl - How can I get this to work? I'm sure I've seen other templates in the past which were meant to be run without an input document, but I don't remember how they worked or where to find them again. :-)

• Finding changes in MongoDB database

  - by Jonathan Knight

  I'm designing a MongoDB database that works with a script that periodically polls a resource and gets back a response which is stored in the database. Right now my database has one collection with four fields , id, name, timestamp and data. I need to be able to find out which names had changes in the data field between script runs, and which did not. In pseudocode, if(data[name][timestamp]==data[name][timestamp+1]) //data has not changed store data in collection 1 else //data has changed between script runs for this name store data in collection 2 Is there a query that can do this without iterating and running javascript over each item in the collection? There are millions of documents, so this would be pretty slow. Should I create a new collection named timestamp for every time the script runs? Would that make it faster/more organized? Is there a better schema that could be used? The script runs once a day so I won't run into a namespace limitation any time soon.

• Interview - Program on Computer

  - by Gilad Naor

  Spent some time searching, couldn't find exactly what I'm after. We like giving hands-on programming exercises as part of the interview process. The interviewee gets a laptop, with the editor and compiler of his choice. He or she then get a programming exercise and has about an hour to code it. Depending on the nature of the question, internet access is either allowed or forbidden. I'm looking for good general questions for a junior developer. I don't care what language they choose to program in. C++ is as good as Python or Scheme, as long as (s)he can program in it (this rules out "can you write a correct copy-constructor" style questions). I just want to see how they code, if their code is self-documenting, if they write tests, check edge-cases, etc. What kind of questions would you ask?

• Authlogic auto login fails on registration with STI User model

  - by Wei Gan

  Authlogin by default is supposed to auto login when the user's persistence token changes. It seems to fail in my Rails app. I set up the following single table inheritance user model hierarchy: class BaseUser < ActiveRecord::Base end class User < BaseUser acts_as_authentic end create_table "base_users", :force => true do |t| t.string "email" t.string "crypted_password" t.string "persistence_token" t.string "first_name" t.string "last_name" t.datetime "created_at" t.datetime "updated_at" t.string "type" end To get auto login to work, I need to explicitly log users in in my UsersController: def create @user = User.new(params[:user]) if @user.save UserSession.create(@user) # EXPLICITLY LOG USER IN BY CREATING SESSION flash[:notice] = "Welcome to Askapade!" redirect_to_target_or_default root_url else render :action => :new end end I was wondering if it's anything to do with STI, or that the table is named "base_users" and not "users". I set it up before without STI and it worked so I'm wondering why once I put in place this hierarchy, it fails. Thanks!

• Many to Many Association Tables - Is it customary to put additional columns in these tables?

  - by Randy Minder

  We've encountered the following situation in our database. We have table 'A' and table 'B' which have a M2M relationship. The association table is named 'AB' and contains a FK column to table 'A' and a FK column to table 'B'. Now we've identified a need to store additional data about this association. For example, a date when the association occurred, and who made the association etc. We've decided to put these additional columns in the 'AB' association table. However, something tells me this is frowned upon by database purists. On the other hand, it makes no sense to us to create yet an additional table to store this associated data. What's the prevailing thought on this?

• Renaming Functions during runtime in PHP.

  - by The Rook

  In PHP 5.3 is there a way to rename a function or "hook" a function. There is the rename_function() within "APD" which has been broken since ~2004. If you try and build it on PHP 5.3 you'll get this error: 'struct _zend_compiler_globals' has no member named 'extended_info' This is a really easy error to fix, just change this line: GC(extended_info) = 1; to CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO; I modified my php.ini and the APD shows up in my phpinfo() as it should. However when i call rename_function() the PHP page doesn't load and I get a segmentation fault in my /var/log/apache2/error.log. Is there anyway to fix APD to work with a modern version of PHP? Or is there another method to rename functions? Why on earth is vital feature not in php!??!?! (Gotta love python :)
