• sIFR works, except for one word in my navigation bar

  - by Jasper

  Hi there, My website uses sIFR and it all seems to work great, except for one word in my navigation bar. The navigation links all work, but the word "Zoeken" (= Search) in front of the search form doesn't get changed to the desired font type. I have checked the header.php of my site, as well as the CSS, but any of the changes that I made, don't seem to work. Could anyone help me out? I am hoping it's just a "piece of cake", but my knowledge of sIFR is close to non-existent. Many thanks! Jasper

• Can you apply a CSS hover effect to an element that’s not a child of the hovered element?

  - by WilliamB

  I was not sure if this is possible or not. I am working in CSS3 animations right now and I need to hover on a link that will effect other div element(non-child) on the page. I was not sure if there is a work around or not. <style type="text/css"> #header { background-color:red; } #header:hover .element { background-color:blue; } .element { background-color:green; } </style> - <header id="header"> <li><a href="#">Hover</a></li> </header> <div class="element" > <p>hello world </p> </div>

• Getting req.params in order in Express JS

  - by Adam Terlson

  In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

• How to remove [^a-z\s] in C++

  - by Steven

  So far I have: int SimplifyText(char chars[], int length) { //To lower for(int i=0; i<length; i++) { chars[i] = tolower(chars[i]); } This function simplifies the text in the first argument which is an array containing the number of characters as given in the second argument The requirements are: tolower all remove all non-alpha characters replace multiple whitespace by one blank. Any leading whitespace at the beginning of the array should be removed completely. The resulting number of characters should be returned as the value of the function. And the annoying part: Another array cannot appear in the function Cannot use strings, only char arrays. Cannot using G++'s extension for setting an array size using a variable. Oh and can't use regex :) I'm stuck with this, any help would be great. :)

• Rails - using :include to find objects based on their child's attributes

  - by adam

  I have a sentence and correction model class Sentence < ActiveRecord::Base has_one :correction class Correction < ActiveRecord::Base belongs_to :sentence and I'm trying find all sentences which don't have a correction. To do this I'm simply looking for corrections which don't exist i.e. whose id = nil. But it is failing and i can't figure out why Sentence.find :all, :include => :correction, :conditions => {:correction => {:id => nil}} Perhaps its the syntax or maybe just the overall approach. Can anyone help?

• Calling a method on a Object says "disallows late binding"

  - by Maury Markowitz

  I have a calls called DtaDate that stores an integer "key", a string name, a string for the date, and a Date object that is created from that string. I have some code that needs to accept a date-like object. I'd like the user to be able to pass in anything date like - a Date object which I'll extract the information from, another DtaDate, a string with the date in it, or even the key, which I'll use to look up the DtaDate from a collection. So I have this: Friend Sub New(NameIn As String, DateFormulaIn As String, Optional FromDateIn As Object = Nothing) [stuff that works] [check that we got a FromDateIn...] If TypeOf FromDateIn Is DtaDate Then fdk = FromDateIn.Key Ans.FromDate = fdk VB tells me that "Option Strict On disallows late binding". The other cases, where a string or integer is the TypeOf, I use CInt or CStr. But this is the first time I've actually run into a case where the casting is a non-base type. What's the trick?

• How to use jquery .animate() to mock 'text-align:right'

  - by mrwienerdog

  I am building a very simple jquery menu. On hover, I have a menu on the right easing to the left margin of my menu container. This is easy, as the text is left aligned within said container. However, I also have a menu on the left, and because the links (left justified) are of differing length, the best I can do is adjust the padding to ease the text a uniform amount between links. Therefor, long link text goes to the right edge of the container, buy short text only makes it about half way. In reading about this, I have learned that you can not modify the text align property as it is non numeric. Is there any other way to do this? I of course tried to go with: $('#selector').css('text-align':'right') but that made the text jump to the right instead of ease. Is there any way to ensure all links ease to the rightmost margin of the container?

• MySQL: Query to obtain recipes using all given ingredients.

  - by John_A

  hi I have the following simplified tables: CREATE TABLE recipe(id int, name varchar(25)); CREATE TABLE ingredient(name varchar(25)); CREATE TABLE uses_ingredient(recipe_id int, name varchar(25)); I want to make a query that returns all id's of recipes that contain both Chicken and Cream. I have tried SELECT recipe_id FROM uses_ingredient INNER JOIN (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id) >= (SELECT COUNT(*) FROM theme); which gives me :"ERROR 1248 (42000): Every derived table must have its own alias" and is probably wrong too. Next I tried SELECT recipe_id FROM (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") AS t INNER JOIN uses_ingredient USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id)>= (SELECT COUNT(*) FROM t); which gives "ERROR 1146 (42S02): Table 'recipedb.t' doesn't exist" I want to avoid creating temporary tables including using ENGINE=MEMORY.

• [grails + xfire] How to handle errors in SOAP services?

  - by Mulone

  Hi all, I'm implementing a web service on the xfire plugin. I was wondering how I'm supposed to handle the errors. I tried with this setup but the error is not returned to the SOAP client: GaSession[] myMethod( String userId ) throws MyException{ GaUser user = GaUser.findByUserId( userId ) if (!user) throw new MyException("user ${userId} does not exist") // do stuff and return valid results } Is there a standard way to handle errors and return them to the client in a clear way? My log is full of messages like: 2010-06-13 18:20:40,926 [Thread-289] DEBUG aegis.XMLClassMetaInfoManager - Mapping file : /com/mycompany/MyClass.aegis.xml not found. Is there a way to fix this? Cheers!

• Adapting Map Iterators Using STL/Boost/Lambdas

  - by John Dibling

  Consider the following non-working code: typedef map<int, unsigned> mymap; mymap m; for( int i = 1; i < 5; ++i ) m[i] = i; // 'remove' all elements from map where .second < 3 remove(m.begin(), m.end(), bind2nd(less<int>(), 3)); I'm trying to remove elements from this map where .second < 3. This obviously isn't written correctly. How do I write this correctly using: Standard STL function objects & techniques Boost.Bind C++0x Lambdas I know I'm not eraseing the elements. Don't worry about that; I'm just simplifying the problem to solve.

  - by The new guy

  I have spent the last 3 hours google and bing for a good asm tutorial(x86 variety). I have been on this site for many of these results. Non have really been sufficient. Mainly because while i like learning theory, i learn it best via practice, while for example pc-asm has about 20-30 pages of theroy before anything practical. I was wondering if there was a tutorial or online pdf (or cheap book(<£20)) that i could use that suits my style of learning. Please state if this is not possibke Thank you for your time

• F# - Function with no arguments?

  - by Rubys

  When thinking in a functional mindset, given that functions are supposed to be pure, one can conclude any function with no arguments is basically just a value. However, reallity gets in the way, and with different inputs, I might not need a certain function, and if that function is computationally expensive, I'd like to not evaluate it if it's not needed. I found a workaround, using let func _ = ... and calling it with func 1 or whatever, but that feels very non-idiomatic and confusing to the reader. This boils down to one question: In F#, Is there a proper way to declare a function with zero arguments, without having it evaluated on declaration?

• How to filter/sort/rank object model nodes?

  - by BCS

  I have some kind of object model and I need to filter and sort it's nodes for some kind of property. What kinds of automated systems exist to generate and select properties of the object model that correlate to what I want? (I'm intentionally being abstract and non-specific) I'm thinking of a system that works kind of like spam filters or supervised classification systems in that given an example data set it identifies rules that find nodes of interest. However I'm looking for a more general system in that it shouldn't require any design time information about the object model. It should work equality well as a spam filter on e-mail, a bug finder on a code base, an interest filter in a newsgroup or bot accounts finder on a social networking site. As long as it can explore the object model via reflection and be given a set of "interesting" nodes, it should be able to find rules that will find more nodes like them.

• Rails: How to have dynamic association

  - by Aaron Dufall

  I'll use an example to explain what behaviour I would like to achieve. If you had a project management app and you added a task, but not all the contributors are users of the app. So when you adding contributors to the task you can enter a user name or email address. Here is the part that I'm finding a little tricky. The task model has many contributors which are linked through the user model, but from this point on I want to achieve 2 things. Store the non members email(this would obviously be quite simple) If that email address was to create an account it would then link that user to the task and remove the temporally saved email. This way, when that user creates an account all the related tasks will already be associated with their email. Is this something that i could achieve with a polymorphic association? or is there something else I should be looking at?

• Accessing Controls Values Before Finishing Page_Load

  - by userk

  Hi. I'm with a problem and want to know if someone can help me. I'm creating a table with some controls and I want to save all control values in every postback. As the controls are just defined after the page_load, I can't solve my problem this way: object o; protected void Page_Load(object sender, EventArgs e) { o = createObject(); Create_Table(); if (Page.IsPostBack) Save_Data(); } I thought I could execute Save_Data() at the begining of every postback event, but I think that should exist a better way to solve my problem. Thanks.

• Need advice on multitab form in ASP.NET MVC

  - by Sasha

  Hi all, i need an advice on how to implement my form. I have a requirement: i need a form that spans through 5 tabs. Each tab has around 10 fields, some of them empty, some of them must contain data from db and be non editable. Each of these tabs must be a part of one form that is submitted to my controller. The question is: what is the best way to implement this? I was thinking about having partial views on each tab, each view would have its own model class. After form gets filled all data from all partials would go to action that will take care of all of it. Any advices? I am using ASP.NET MVC 1, Entity Framework 1, mvc extensions from Telerik and jQuery

• C++ STL: Array vs Vector: Raw element accessing performance

  - by oh boy

  I'm building an interpreter and as I'm aiming for raw speed this time, every clock cycle matters for me in this (raw) case. Do you have any experience or information what of the both is faster: Vector or Array? All what matters is the speed I can access an element (opcode receiving), I don't care about inserting, allocation, sorting, etc. I'm going to lean myself out of the window now and say: Arrays are at least a bit faster than vectors in terms of accessing an element i. It seems really logical for me. With vectors you have all those security and controlling overhead which doesn't exist for arrays. (Why) Am I wrong? No, I can't ignore the performance difference - even if it is so small - I have already optimized and minimized every other part of the VM which executes the opcodes :)

• Should properties in C# perform a lot of work?

  - by Hamish Grubijan

  When a property is read from or is assigned to, one would not expect it to perform a lot of work. When setSomeValue(...) and getSomeValue(...) methods are used instead, one should not be that surprised that something non-trivial might be going on under the hood. However, now that C# gave the world Properties, it seems silly to use getter and setter methods instead. What is your take on this? Should I mark this Q as a community wiki? Thanks.

• How do you insert new entries into an Access db table through an ASP.net website?

  - by CGF

  I need to insert new records into an Access database. I'm using Visual Studio 2008 and firstly create a asp.net website. I can connect to the information in Access databse using dataview or gridview and can query a particular entry (ie. Proposal No. -brings up all details linking to that proposal). I can then edit the details of that proposal and this would update the Access Db. What I need to do is to have a form that simply enters new details for a new customer. ie. Enter name [__] Enter Adress[__]. Then for this to update the database. By using the gridview or dataview I am able to view all fields that exist in the table and edit them. Is there a way that I can get a blank gridview/dataview template (which includes all the fields in the table) and fill it out to then update the database? Thanks

• Sharing information between applications

  - by Zé Carlos

  My question is very simple to expose: I have a few aplications that share data between then. I need a way to support that data sharing (cross several computers) and when one aplication changes data, others should be notified about that. My question is about what tecnologies could be usefull to me. The solution i realise at this moment is to have a database to share data and an external publish-subscribe system (like http://pubsub.codeplex.com/) to notify all applications when the data is changed. But i belive that could exist some helpfull solutions. Do you know any of then? Thanks.

• How does a youtube embed suppress the buffering of a video file?

  - by usingtechnology

  When a youtube video is displayed within an external site, a poster image is displayed but the actual video is not loaded until the user clicks the play button. At that point, the video file begins to buffer and the video plays. This seems to be different than many sites, where a flash video is embedded and the video begins to buffer automatically in the background on page load, regardless of whether the video is set to autoplay or not. How would you set up a flash video (non-youtube) to have the same behavior as youtube, where buffering does not occur at pageload? Is it an output setting that is selected during the flash video rendering process, or is it accomplished using a different method?
