• Can I include a view in Kohana 3 that is not within `application/views`?

  - by alex

  I am building a staff area for a website, which is completely different to the main brochure style site. I have 2 Kohana systems setup. I realise they can both share the same system and modules folder. Now, with the second one, I want to make the main template view a view in a different folder. I tried this in my base controller $this->template = DOCROOT . '../~new2/application/views/template.php'; But Kohana is looking for it in its own views folder as evident by the error I received. I even put a var_dump(file_exists($this->template)); // true to be sure it was finding the correct file. Is there a way to add a template file that is not within the views folder, without hacking the core Kohana code (and if I'm lucky not extending and overloading the view class).

• Why I cant be able to change the UITableViewCell detailTextLabel's frame (just the label's position)?

  - by Simon

  Hi.. I am having a table view with default UITableViewCell of style UITableViewCellStyleValue2. I just want to move detailTextLabel few pixels to the right. I know it makes no sense to adjust its width and height :). I am trying to set detailTextLabel's frame with my x and y value. But its not affecting the its frame. I prefer to use default UITableViewCell, in this case, over a customized cell because the default UITableViewCell automatically manages the text alignment and centering of the labels.. How to change UITableViewCell detailTextLabel's frame? Am I allowed to change its frame? Thanks everyone..

• Is there a way to get a reference to all the paragraphs or headings in a web page in JavaScript?

  - by mattbd

  I'm writing a simple Greasemonkey script to strip out all the images, headings and paragraphs from a web page (it's because someone wants to use images of several popular websites with the images and text removed in a presentation about branding of websites). I've figured out how to do so with images by using a for loop and the document.images array like this: var i = 0; var imglngth = document.images.length; for(i=0;i<imglngth;i++) { document.images[i].style.display="none"; } However, I don't believe there's an object representing paragraphs or headers. Any suggestions as to how I could implement this?

• PHP HTML variable

  - by Abakiz Myth

  In Coldfusion we have the variable: <cfsavecontent name="HTML_content"> <div class="test_div" style="color:#FFF;">Test</div> </cfsavecontent> Within PHP there seems to be no way of doing this without some really hacky function or escaping double quotes. I'm trying to create emails (large html documents) within the same page by saving the email content and simply mailing it but it seems like there's no way of doing this within PHP without using $var = "\"crap\""; Can somebody point me in the right direction?

• Use jQuery to match variable text?

  - by VUELA

  Hello! I have a sidebar navigation that lists blog entry titles down the side of the page. I am trying to write some jquery that will check the text in the title of the current full blog entry page and match it with the corresponding title in the sidebar navigation so that I can apply a class to style for an active state link ... but I'm not quite getting it! Here is the link to an example page: http://ncw-commercial.com/property-listings/eastpoint-plaza-lot.html, and below is my current code. I have also tried using :contains but could not figure out how to get that to work with a variable rather than direct text. $('.single-journal-entry-wrapper .journal-entry .title').each(function(){ var activeTitle = $(this).text(); $(".feedburnerFeedBlock .headline a").filter(function(index) { return $(this).text() == "activeTitle"; }).parent().addClass("activeTitle"); });

• int i vs int index etc. Which one is better?

  - by Earlz

  Coming from a C background I've always used int i for generic loop variables. Of course in big nested loops or other complex things I may use a descriptive name but which one had you rather see? int i; for(i=0;i<Controls.Count;i++){ DoStuff(Controls[i]); } or int index; for(index=0;index<Controls.Count;index++){ DoStuff(Controls[index]); } In the current project I am working on there are both of these styles and index being replaced by ndx. Which one is better? Is the i variable too generic? Also what about the other C style names? i, j, k Should all of these be replaced by actual descriptive variables?

• AS3: Performance question calling an event function with null param

  - by adehaas

  Lately I needed to call a listener function without an actual listener like so: foo(null); private function foo(event:Event):void { //do something } So I was wondering if there is a significant difference regarding performance between this and using the following, in which I can prevent the null in calling the function without the listener, but am still able to call it with a listener as well: foo(); private function foo(event:Event = null):void { } I am not sure wether it is just a question of style, or actually bad practice and I should write two similar functions, one with and one without the event param (which seems cumbersome to me). Looking forward to your opinions, thx.

• How can code in a JavaScript file get the file's URL?

  - by dalbaeb

  I need to dynamically load a CSS stylesheet into a page that's on a different domain. How can I get the complete URL of the JS file to use in the href attribute of the stylesheet? For instance, here is the structure: http://bla.com/js/script.js http://bla.com/css/style.css I want to dynamically load the stylesheet into a page http://boo.net/index.html. The problem is, I don't know the bla.com bit in advance, just the fact that the stylesheet is in ../css/ relative to the JS file. The script is, of course, included on index.html. jQuery's fine too.

• Declaration and initialization of local variables - what is most C++ like?

  - by tuergeist

  Hi, I did not find any suitable questions answered yet, so I'd like to know what is "better" C++ style in the mean of performance and/or memory. Both codes are inside a method. The question is: When to declare long prio? And what are the implications? Code 1 while (!myfile.eof()) { getline(myfile, line); long prio = strtol(line); // prio is declared here // put prio in map... // some other things } Code 2 long prio; // prio is declared here while (!myfile.eof()) { getline(myfile, line); prio = strtol(line); // put prio in map... // some other things }

• Good assembly tutorial for windows with eiter fasm or nasm

  - 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

• Functions without arguments, with unit as argument in scala

  - by scout

  def foo(x:Int, f:Unit=>Int) = println(f()) foo(2, {Unit => 3+4} //case1 def loop:Int = 7 foo(2, loop) //does not compile changing loop to //case 2 def loop():Int = 7 foo(2, loop) // does not compile changing loop to //case 3 def loop(x:Unit): Int = 7 //changing according to Don's Comments foo(2,loop) // compiles and works fine should'nt case 1 and case 2 also work? why are they not working? defining foo as def foo(x:Int, y:()=>Int) then case 2 works but not case 1. Arent they all supposed to work, defining the functions either way. //also i think ()=Int in foo is a bad style, y:=Int does not work, comments??

• height: auto does not work to automatically resize header

  - by slevin

  I'm trying to do a simple thing in CSS I have a header tag and inside that a couple of h tags. So, in order to have a responsive design I do height:auto; inside the header tag, so it will automatically stretch to contain the h tags. Right? But does not work, headeris just a line in the top of the page. t should stretch to contain the titles, right? What am I missing? Is it a good practice to put CSS in the h tags and not style header at all? So h tags will be like the header in user's eye? Thanks in advence Check it here

• Why does this PNG file look so poorly when embedded as a resource in a Qt project?

  - by George Edison

  Here is the PNG file and what it looks like in a QWebView when accessed via http://sstatic.net/so/img/logo.png: When accessed via HTTP: <img src="http://sstatic.net/so/img/logo.png" width='250' height='61' /> When accessed via a resource: <img src="qrc:/images/logo.png" width='250' height='61' /> As you can see, the only modification was the src attribute of the image tag... why the drop in quality? Edit: The file is being shrunk via width: and height: in the style attribute, if that makes a difference. I updated the code.

• jQuery: Fade not working

  - by Rosarch

  For some reason, jQuery's fade effect isn't working. Could it be because of the code? This function does everything it is supposed to, aside from the fading. It gets called at the correct time. function moveToTerm(original_course, helper, term) { var cloned_course = original_course.clone(true); original_course.addClass('already-scheduled'); helper.fadeOut(function() { cloned_course.appendTo(term).attr('style', '').fadeIn("slow"); }); } UPDATE: It fails in both FF 3.5.9 and IE 8.

• Deleting a cookie in Javascript not working

  - by DisgruntledGoat

  I have a site where authentication is done externally (which I can't access), so I'm creating a cookie on login in order to display a welcome message to the user. Creating the cookie works fine, I write to document.cookie when the login form submits. But deleting the cookie doesn't work. Here's my code (logout.php does the external authentication stuff): <a href="http://external.com/logout.php" style="float:right" onclick="document.cookie='BRLOG=; expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/; domain=.example.com;'">Logout</a>

• INSERT INTO ... SELECT ... vs dumping/loading a file in MySQL

  - by Daniel Huckstep

  What are the implications of using a INSERT INTO foo ... SELECT FROM bar JOIN baz ... style insert statement versus using the same SELECT statement to dump (bar, baz) to a file, and then insert into foo by loading the file? In my messing around, I haven't seen a huge difference. I would assume the former would use more memory, but the machine that this runs on has 8GB of RAM, and I never even see it go past half used. Are there any huge (or long term) performance implications that I'm not seeing? Advantages/disadvantages of either?
