  • Noobie Jquery Question

    - by piratebill
    I've been working with Jquery fro a grand total of two hours now. Up until this point I have made this really simple FAQ page. <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#void").click(function(event) { event.preventDefault(); }); $('#faq').find('dd').hide().end().find('dt').click(function() { $(this).next().slideToggle(); }); }); </script> <dl id="faq"> <dt><a href="" id="void">Coffee</a></dt> <dd>- black hot drink</dd> <dt><a href="" id="void">Milk</a></dt> <dd>- white cold drink</dd> </dl> The problem is only the first item is working. My questions are, why is only the first entree working and how do I fix it? I've tried using an each() but I am unsure where to put it.

  • Thread synchronization and aborting.

    - by kubal5003
    Hello, I've got a little problem with ending the work of one of my threads. First things first so here's the app "layout": Thread 1 - worker thread (C++/CLI) - runs and terminates as expected for(...) { try { if(TabuStop) return; System::Threading::Monitor::Enter("Lock1"); //some work, unmanaged code } finally { if(stop) { System::Threading::Monitor::Pulse("Lock1"); } else { System::Threading::Monitor::Pulse("Lock1"); System::Threading::Monitor::Wait("Lock1"); } } } Thread 2 - display results thread (C#) while (WorkerThread.IsAlive) { lock ("Lock1") { if (TabuEngine.TabuStop) { Monitor.Pulse("Lock1"); } else { Dispatcher.BeginInvoke(RefreshAction); Monitor.Pulse("Lock1"); Monitor.Wait("Lock1", 5000); } } // Thread.Sleep(5000); } I'm trying to shut the whole thing down from app main thread like this: TabuEngine.TabuStop = true; //terminates nicely the worker thread and if (DisplayThread.IsAlive) { DisplayThread.Abort(); } I also tried using DisplayThread.Interrupt, but it always blocks on Monitor.Wait("Lock1", 5000); and I can't get rid of it. What is wrong here? How am I supposed to perform the synchronization and let it do the work that it is supposed to do? //edit I'm not even sure now if the trick with using "Lock1" string is really working and locks are placed on the same object..

  • SQL trigger to delete rows from database

    - by wpearse
    I have an industrial system that logs alarms to a remotely hosted MySQL database. The industrial system inserts a new row whenever a property of the alarm changes (such as the time the alarm was activated, acknowledged or switched off) into a table named 'alarms'. I don't want multiple records for each alarm, so I have set up two database triggers. The first trigger mirrors each new record to a second table, creating/updating rows as required: CREATE TRIGGER `mirror_alarms` BEFORE INSERT ON `alarms` FOR EACH ROW INSERT INTO `alarm_display` (Tag,...,OffTime) VALUES (new.Tag,...,new.OffTime) ON DUPLICATE KEY UPDATE OnDate=new.OnDate,...,OffTime=new.OffTime The second trigger should execute after the first and (ideally) delete all rows from the alarms table. (I used the Tag property of the alarm because the Tag property never changes, although I suspect I could just use a 'DELETE FROM alarms WHERE 1' statement to the same effect). CREATE TRIGGER `remove_alarms` AFTER INSERT ON `alarms` FOR EACH ROW DELETE FROM alarms WHERE Tag=new.Tag My problem is that the second trigger doesn't appear to run, or if it does, the second trigger doesn't delete any rows from the database. So here's the question: why does my second trigger not do what I expect it to do?

  • Can I get an XPathNodeIterator directly from an XPath?

    - by Val
    I hope I'm just missing something obvious. I have a number of repeating nodes in an XML document: <root> <parent> <child/> <child/> </parent> </root> I need to examine the contents of each of the <child> elements in turn, so I need an XPathNodeIterator containing the nodeset of all the <child> nodes. If I have an XPath that would select the child nodes, e.g. /root/parent/child, is there any way to feed that directly to a new XPathNodeIterator? Everything I see in the docs and examples indicates I have to first get an XPathNavigator to the <parent>, then Select the child nodes, like: XPathNavigator nav = datasource.CreateNavigator().SelectSingleNode( "/root/parent" ); XPathNodeIterator it = nav.Select( "./child" ); foreach ( child in it ) { /* do something */ } I was hoping to skip the XPathNavigator, and intialize the XPathNodeIterator with XPath to the child nodes directly, something like: XpathNodeIterator it = new XpathNodeIterator("/root/parent/child"); foreach ( child in it ) { /* do something */ } Possible? The benefit is not only saving a line of code, but I can use a single XPath expression, rather than splitting the path to the <child> nodes in two, first to get the parent element, then to select its children.

  • jquery find() - how to exclude certain descendants, and their children?

    - by jammypeach
    I have markup similar to this: <div class='wrapper plugin'> //some content <div class='child-wrapper plugin'> //some more content <div> <ul> <li><div class='cliky'>clicky!</div></li> </ul> </div> </div> <div class='cliky'>clicky!</div> </div> I need to be able to select the first .clicky div only, not any .clicky divs inside a .plugin > .plugin div. The wrapper has .plugin class too - might seem counter-intuitive so another way to view it is this: I want to get the .clicky children of a given .plugin div, but not .plugin .plugin .clicky. Here's the problem - the depth of each .clicky element (or indeed, the number of them) is unknown and variable in relation to the wrappers. One could be immediately below the first wrapper, or inside 10 <ul>s. I've tried selectors like: $('.wrapper').find('.clicky').not('.plugin > .clicky'); But they still selected child .clicky. How would I be able to filter out .plugin and any children of .plugin from my selector before using find()?

  • Does anyone still believe in the Capability Maturity Model for Software?

    - by Ed Guiness
    Ten years ago when I first encountered the CMM for software I was, I suppose like many, struck by how accurately it seemed to describe the chaotic "level one" state of software development in many businesses, particularly with its reference to reliance on heroes. It also seemed to provide realistic guidance for an organisation to progress up the levels improving their processes. But while it seemed to provide a good model and realistic guidance for improvement, I never really witnessed an adherence to CMM having a significant positive impact on any organisation I have worked for, or with. I know of one large software consultancy that claims CMM level 5 - the highest level - when I can see first hand that their processes are as chaotic, and the quality of their software products as varied, as other, non-CMM businesses. So I'm wondering, has anyone seen a real, tangible benefit from adherence to process improvement according to CMM? And if you have seen improvement, do you think that the improvement was specifically attributable to CMM, or would an alternative approach (such as six-sigma) have been equally or more beneficial? Does anyone still believe? As an aside, for those who haven't yet seen it, check out this funny-because-its-true parody

  • C# Finding 2 positions 1-dimArray

    - by Chris
    Hello, In a method i am calculating the longest row of elements. The 1-dim array is filled up with random values (0 or 1). The method looks up the longest row (being 0 or 1, whatever is the longest). Meaning in for example: 1110100 --> the longest row would be 3 (3 * 1) 0110000 --> the longest row would be 4 (4 * 0) My problem is i am trying to perform some type of linear search to show the position of the row in the array. The first example has the longest row of 3 elements (3 times 1). For 1110100 the position in the array would be 0 - 2 (index) For 0110000 the position in the array would be 3 - 6 (index) I have been trying with foreaches, for loops etc..but i cannot seem to get the proper indexes of both. Cannot seem to display both positions properly. For the first example the correct output wouldbe: The largest row of same elements of the array consists of 3 elements on the position 0 - 2. The longest row of elements gets of same elements get calculated as the following: public int BerekenDeelrij (int [] table) ( int count = 0; final int value = 0; int largest = 0; foreach (int value in table) ( if (value == last value) counter + +; else ( largest = Math.Max largest (largest, counter); final value = value count = 1; ) ) Math.Max return (largest, counter); ) Best Regards.

  • Are the formatted addresses of a Google location unique?

    - by Hans
    I want our users of a web site to be able to either search and pick an address or mark a location on a map decide how accurate this address/location is I am in the process of implementing the first part with jquery, jquery ui's autocomplete, google map, and google geocoder. For the second part I will generate a radiobutton list based on the address elements/alternatives of the first part on the client side with jquery. My concern, however, is how to convey the choices to the server side. The Google geocoder includes a number of useful metadata that I want to store. A possibility is to store the complete json object in a hidden form field, but I can't trust the users. Such a solution would enable an unfriendly insertion of spam in the data. If the addresses/locations would have a unique identifyer I could store just these and let the server refetch/evaluate the data. The alternative geonames.org web service has such ids. But are for example the formatted addresses of a Google location unique? Any tips?

  • Fast (de)serialization on iPhone

    - by Jacob Kuypers
    I'm developing a game/engine for iPhone OS. It's the first time I'm using Objective-C. I made my own binary format for geometry data and for textures I'm focusing on PVRTC. That should be the optimal approach as far as speed and space are concerned. I really want to keep loading time to a minimum and - if possible - be able to save very fast as well. So now I'm trying to make my "Entity" stuff persistent without sacrificing performance. First I wanted to use NSKeyedArchiver. From what I've heard, it's not very fast. Also, what I want to serialize is mostly structs made of floats with some ints and strings, so there isn't really a need for all that "object graph" overhead. NSArchiver would have been more appropriate, but they kicked that off the iphone for some reason. So now I'm thinking about making my own serialization scheme again. Am I wrong in thinking that NSKeyedArchiver is slow (I only read that, haven't tested it myself)? If so, what's the best way to encode/decode structs (with no pointers, mostly floats) without sacrificing speed?

  • Error 2025: The supplied DisplayObject must be a child of the caller

    - by Mocca
    Hi, sorry, new to actionscript 3. I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed. Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error) Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large) Does anyone have further insight? Thanks! function display(num:Number):void //num: image number { ... oldImg = newImg; ClassReference = getDefinitionByName("Class"+num) as Class; imgBD = new ClassReference(0,0); newImg = new Bitmap(imgBD); images.addChild(newImg); newImg.x=0; newImg.y=0; } function onEnter(evt:Event):void { if (oldImg) { if (oldImg.alpha > 0) oldImg.alpha -= 0.15; **else images.removeChild(oldImg);** } ... }

  • IE7 & 8 not fireing jQuery click events for elements appended inside a table

    - by Keith
    I have an IE bug that I'm not sure how to fix. Using jQuery I'm dynamically moving a menu to appear on an element on mouseover. My code (simplified) looks something like this: $j = jQuery.noConflict(); $j(document).ready(function() { //do something on the menu clicks $j('div.ico').click(function() { alert($j(this).parent().html()); }); setUpActions('#tableId', '#menuId'); }); //on mouseover set up the actions menu to appear on mouseover function setUpActions(tableSelector, menuSelector) { $j(tableSelector + ' div.test').mouseover(function() { //note that append will move the underlying //DOM element with all events from it's old //parent to the end of this one. $j(this).append($j(menuSelector).show()); }); } This menu doesn't seem to register events correctly for the menu after it's been moved in IE7, IE8 and IE8-as-IE7 (yeah MS, that's really a 'new rendering engine' in IE8, we all believe you). It works as expected in everything else. You can see the behaviour in a basic demo here. In the demo you can see two examples of the issue: The image behind the buttons should change on hover (done with a CSS :hover selector). It works on the first mouseover but then persists. The click event doesn’t fire – however with the dev tools you can manually call it and it is still subscribed. You can see (2) in IE8's dev tools: Open page in IE8 Open dev tools Select "Script" tab and "Console" sub-tab Type: $j('#testFloat div.ico:first').click() to manually call any subscribed events There will be an alert on the page This means that I'm not losing the event subscriptions, they're still there, IE's just not calling them when I click. Does anyone know why this bug occurs (other than just because of IE's venerable engine)? Is there a workaround? Could it be something that I'm doing wrong that just happens to work as expected in everything else?

  • [php] Firefox refreshes page 1, even after redirection to page 2

    - by Znarkus
    Hi! This is a quite weird and annoying problem, which is reproduced with the script below. Say we have two pages: script.php and script.php?second. Page 1 creates some database entries and redirects to page 2. On page 2, the user is presented with an editor for said entries. If page 1 for some reason crashes on the first try, and prints some error message, a strange thing will happend. If we refresh page 1 (and this time it redirects fine), every consecutive refresh (of page 2) will actually refresh page 1 and again redirect to page 2. In the above example this would create new database entries for every refresh, which is the problem I want to circumvent by redirecting to page 2. <?php header('Content-type: text/plain'); session_start(); if (!isset($_GET['second'])) { $_SESSION['counter'] = isset($_SESSION['counter']) ? $_SESSION['counter'] + 1 : 1; /*$_SESSION['counter'] = 0; exit('asd');*/ header("Location: {$_SERVER['PHP_SELF']}?second", true, 303); exit; } echo "Counter: {$_SESSION['counter']}"; To try the above complete script, first run it with the commented code intact, then by enabling the commented code. I've tried 301, 302 and 303 redirections. Does someone know why this is happening?

  • Viewing recently edited etherpads (note new 'etherpad' tag for open sourced etherpad code!)

    - by dreeves
    Prescript: The amazing etherpad was recently open sourced. Get it here: http://code.google.com/p/etherpad. This is the first question that I know of on StackOverflow about the etherpad code. If you're part of the etherpad open source community, you might want to subscribe to the RSS feed for questions tagged 'etherpad' just in case this catches on! My actual question, which assumes you have etherpad installed on your own server: First, here's a query to view recently edited pads: SELECT id,lastWriteTime,creationTime,headRev FROM PAD_SQLMETA ORDER BY lastWriteTime, headRev; Or, if you want to run it from a unix prompt: mysql -u root -pPASSWD etherpad -e "select id,lastWriteTime,creationTime,headRev from PAD_SQLMETA order by lastWriteTime, headRev" That's handy, however lastWriteTime actually gets updated every time someone so much as views a pad in their browser. I'd rather sort the pads by when they were actually last edited. There's probably a fancy SQL query involving a join with another table that would show actual last edit time. Does anyone know what that is? Alternatively, you could have a script that notices when headRev changes but that doesn't seem like the cleanest way to do it.

  • Help dealing with data dependency between two registration forms

    - by franko75
    I have a tricky issue here with a registration of both a user and his/her pet. Both the user and the pet are treated as separate entities and both require separate registration forms. However, the user's pet has to be linked to the user via a foreign key in the database. The process is basically that when a new user joins the site, firstly they register their pet, then they register themselves. The reason for this order is to check their pet's eligibility for the site (there are some criteria to be met) first, instead of getting the user to sign up only to then find out their pet is ineligible. It is this ordering of the form submissions which is causing me a bit of a headache, as follows... The site is being developed with an MVC framework, and the User registration process is managed via a method in a User_form controller, while the pet registration process is managed via a method in the Pet_form controller. The pet registration form happens first, and the pet data can be saved without the owner_id at this stage, with the user id possibly being added (e.g by retrieving pet's id from session) following user registration. However, doing it this way could potentially result in redundant data, where pet records would be created in the database, but if the user doesn't actually register themselves too, then the pets will be ownerless records in the DB. Other option is to serialize the new pet's data at the pet registration stage, don't save it to the DB until the user fills out their registration form. Once the user is created, i can pass serialised data AND the owner_id to a method in the Pet Model which can update the DB. However, I also need to set the newly created $pet to $this-pet which I then access for a sequence of other related forms. Should I just set the session variable in the model method? Then in the Pet controller constructor, do a check for pet stored in session, if yes, assign to $this-pet... If this makes any sense to anybody and you have some advice, i'd be grateful to hear it!

  • Approach for caching data from data logger

    - by filip-fku
    Greetings, I've been working on a C#.NET app that interacts with a data logger. The user can query and obtain logs for a specified time period, and view plots of the data. Typically a new data log is created every minute and stores a measurement for a few parameters. To get meaningful information out of the logger, a reasonable number of logs need to be acquired - data for at least a few days. The hardware interface is a UART to USB module on the device, which restricts transfers to a maximum of about 30 logs/second. This becomes quite slow when reading in the data acquired over a number of days/weeks. What I would like to do is improve the perceived performance for the user. I realize that with the hardware speed limitation the user will have to wait for the full download cycle at least the first time they acquire a larger set of data. My goal is to cache all data seen by the app, so that it can be obtained faster if ever requested again. The approach I have been considering is to use a light database, like SqlServerCe, that can store the data logs as they are received. I am then hoping to first search the cache prior to querying a device for logs. The cache would be updated with any logs obtained by the request that were not already cached. Finally my question - would you consider this to be a good approach? Are there any better alternatives you can think of? I've tried to search SO and Google for reinforcement of the idea, but I mostly run into discussions of web request/content caching. Thanks for any feedback!

  • MySQL - What is wrong with this query or my database? Terrible performance.

    - by Moss
    SELECT * from `employees` a LEFT JOIN (SELECT phone1 p1, count(*) c, FROM `employees` GROUP BY phone1) b ON a.phone1 = b.p1; I'm not sure if it is this query in particular that has the problem. I have been getting terrible performance in general with this database. The table in question has 120,000 rows. I have tried this particular query remotely and locally with the MyISAM and InnoDB engines, with different types of joins, and with and without an index on phone1. I can get this to complete in about 4 minutes on a 10,000 row table successfully but performance drops exponentially with larger tables. Remotely it will lose connection to the server and locally it brings my system to its knees and seems to go on forever. This query is only a smaller step I was trying to do when a larger query couldn't complete. Maybe I should explain the whole scenario. I have one big flat ugly table that lists a bunch of people and their contact info and the info of the companies they work for. I'm trying to normalize the database and intelligently determine which phone numbers apply to individual people and which apply to an office location. My reasoning is that if a phone number occurs multiple times and the number of occurrence equals the number of times that the street address it is attached to occurs then it must be an office number. So the first step is to count each phone number grouping by phone number. Normally if you just use COUNT()...GROUP BY it will only list the first record it finds in that group so I figured I have to join the full table to the count table where the phone number matches. This does work but as I said I can't successfully complete it on any table much larger than 10,000 rows. This seems pathetic and this doesn't seem like a crazy query to do. Is there a better way to achieve what I want or do I have to break my large table into 12 pieces or is there something wrong with the table or db?

  • Does playing a Program from VS2005 cause a program to work any different than the .exe file?

    - by Bryan
    There is a program where I work that works fine when running the .exe file but works differently from expected when opened in VS2005 and played from there. I am therefore asking on here if anyone knows of anything that would work in the .exe file but not the debug from VS? I am not able to post the code for the buttons I'm talking about but I'll try to explain the best I can. There is a receiver hooked up to the computer. When the button is pressed on the program, it shows a message and waits for a signal to be received. After the signal is heard the first message box is supposed to close and another is supposed to open. When using the .exe file this happens just fine. However when playing from the program from VS2005 (the same one from which the .exe was made) the second message doesn't come up when it is supposed to and when I can make it come up, the first box doesn't close. There is also a timer involved if that helps. Also, is there a fundamental difference between how the two operate when executing the program? If I need to make anything more clear or give more details please let me know.

  • Import CSV to class structure as the user defines

    - by Assimilater
    I have a contact manager program and I would like to offer the feature to import csv files. The problem is that different data sources order the fields in different ways. I thought of programming an interface for the user to tell it the field order and how to handle exceptions. Here is an example line in one of many possible field orders: "ID#","Name","Rank","Address1","Address2","City","State","Country","Zip","Phone#","Email","Join Date","Sponsor ID","Sponsor Name" "Z1234","Call, Anson","STU","1234 E. 6578 S.","","Somecity","TX","United States","012345","000-000-0000","[email protected]","5/24/2010","z12343","Quantum Independence" Notice that in one data field "Name" there is a comma to separate last name and first name and in another there is not. My plan is to have a line for each field (ie ID, Name, City etc.) and a statement "import to" and list box with options like: Don't Import, BusinessJoin Date, First Name, Zip and the program recognizes those as properties of an object... I'd also like the user to be able to record preset field orders so they can re-use them for csv files from the same download source. Then I also need it to check if a record all ready exists (is there a record for Anson Call all ready?) and allow the user to tell it what to do if there is a record (ie mailing address may have changes, so if that field is filled overwrite it, or this mailing address is invalid, leave the current data untouched for this person, overwrite the rest). While I'm capable of coding this...i'm not very excited about it and I'm wondering if there's a tool or set of tools out there to all ready perform most of this functionality... I hope this makes sense...

  • NHibernate + Fluent long startup time

    Hi all, am new to NHibernate. When performing below test took 11.2 seconds (debug mode) i am seeing this large startup time in all my tests (basically creating the first session takes a tone of time) setup = Windows 2003 SP2 / Oracle10gR2 latest CPU / ODP.net 2.111.7.20 / FNH 1.0.0.636 / NHibernate 2.1.2.4000 / NUnit 2.5.2.9222 / VS2008 SP1 using System; using System.Collections; using System.Data; using System.Globalization; using System.IO; using System.Text; using System.Data; using NUnit.Framework; using System.Collections.Generic; using System.Data.Common; using NHibernate; using log4net.Config; using System.Configuration; using FluentNHibernate; [Test()] public void GetEmailById() { Email result; using (EmailRepository repository = new EmailRepository()) { results = repository.GetById(1111); } Assert.IsTrue(results != null); } public class EmailRepository : RepositoryBase { public EmailRepository():base() { } } In my RepositoryBase public T GetById(object id) { using (var session = sessionFactory.OpenSession()) using (var transaction = session.BeginTransaction()) { try { T returnVal = session.Get(id); transaction.Commit(); return returnVal; } catch (HibernateException ex) { // Logging here transaction.Rollback(); return null; } } } The query time is very small. The resulting entity is really small. Subsequent queries are fine. Its seems to be getting the first session started. Has anyone else seen something similar?

  • Advice on Linq to SQL mapping object design

    - by fearofawhackplanet
    I hope the title and following text are clear, I'm not very familiar with the correct terms so please correct me if I get anything wrong. I'm using Linq ORM for the first time and am wondering how to address the following. Say I have two DB tables: User ---- Id Name Phone ----- Id UserId Model The Linq code generator produces a bunch of entity classes. I then write my own classes and interfaces which wrap these Linq classes: class DatabaseUser : IUser { public DatabaseUser(User user) { _user = user; } public Guid Id { get { return _user.Id; } } ... etc } so far so good. Now it's easy enough to find a users phones from Phones.Where(p => p.User = user) but surely comsumers of the API shouldn't need to be writing their own Linq queries to get at data, so I should wrap this query in a function or property somewhere. So the question is, in this example, would you add a Phones property to IUser or not? In other words, should my interface specifically be modelling my database objects (in which case Phones doesn't belong in IUser), or are they actually simply providing a set of functions and properties which are conceptually associated with a User (in which case it does)? There seems drawbacks to both views, but I'm wondering if there is a standard approach to the problem. Or just any general words of wisdom you could share. My first thought was to use extension methods but in fact that doesn't work in this case.

  • Getting moved out of a development job

    - by Jay
    I'm a year out of college and I started my first dev job at a small (<15 people) company several months ago. It was an internship position that recently turned full time. The position started out as development but for full time I got offered a grab bag of positions: qa, docs, call support and some dev work. It's clear that my employers feel I am lacking dev skills, which is true. I did not major in CS in college and did not have much dev experience. However, I'm convinced that I can be a good developer and I will be a good developer once given the chance to write lots of code. My question is simple: what should I do? As I see it, there are two options. Work hard in the non-dev duties so that my employers may eventually give me significant dev responsibilities. Look for a new job where I will be a developer first and an all purpose guy second (if at all). Thanks guys.

  • Codeigniter only loads the default controller

    - by fh47331
    I am very new to CodeIgniter, but have been programming PHP for ages. I'm writing some software at the moment and using CI for the first time with it. The default controller is set to the first controller I want to action call 'login' (the controller is login.php, the view is login.php. When the form is submitted it calls the 'authenticate' controller. This executes fine, process the login data correctly and then does a redirect command (without any output to the screen prior) to the next page in this case 'newspage'. The problem is that the redirect, never reaches 'newspage' but the default controller runs again. It doesn't matter what I put ... ht tp://domain.name/anything ... (yes im using .htaccess to remove the index.php) the anything never gets called, just the default controller. I have left the standard 'welcome.php' controller and 'welcome_message.php' in the folders and even putting ht tp://domain.name/welcome all I get is the login screen! (Obviously there shouldn't be a space between the http - thats just done so it does not show as a hyperlink!) Can anyone tell me what i've done wrong!

  • C++ Template Class Constructor with Variable Arguments

    - by david
    Is it possible to create a template function that takes a variable number of arguments, for example, in this Vector< T, C class constructor: template < typename T, uint C > Vector< T, C >::Vector( T, ... ) { assert( C > 0 ); va_list arg_list; va_start( arg_list, C ); for( uint i = 0; i < C; i++ ) { m_data[ i ] = va_arg( arg_list, T ); } va_end( arg_list ); } This almost works, but if someone calls Vector< double, 3 ( 1, 1, 1 ), only the first argument has the correct value. I suspect that the first parameter is correct because it is cast to a double during the function call, and that the others are interpreted as ints and then the bits are stuffed into a double. Calling Vector< double, 3 ( 1.0, 1.0, 1.0 ) gives the desired results. Is there a preferred way to do something like this?

  • Using items in a list as arguments

    - by Travis Brown
    Suppose I have a function with the following type signature: g :: a -> a -> a -> b I also have a list of as—let's call it xs—that I know will contain at least three items. I'd like to apply g to the first three items of xs. I know I could define a combinator like the following: ($$$) :: (a -> a -> a -> b) -> [a] -> b f $$$ (x:y:z:_) = f x y z Then I could just use g $$$ xs. This makes $$$ a bit like uncurry, but for a function with three arguments of the same type and a list instead of a tuple. Is there a way to do this idiomatically using standard combinators? Or rather, what's the most idiomatic way to do this in Haskell? I thought trying pointfree on a non-infix version of $$$ might give me some idea of where to start, but the output was an abomination with 10 flips, a handful of heads and tails and aps, and 28 parentheses. (NB: I know this isn't a terribly Haskelly thing to do in the first place, but I've come across a couple of situations where it seems like a reasonable solution, especially when using Parsec. I'll certainly accept "don't ever do this in real code" if that's the best answer, but I'd prefer to see some clever trick involving the ((->) r) monad or whatever.)
