  • How do I remove a button from a view controller's toolbar on the iPhone?

    - by Tony
    I have code that works great for adding a button to the toolbar: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,shuffleBarItem,flexibleSpace,nil]; self.toolbarItems = toolbarItems; However, I also want to be able to remove toolbar items. When I use the below method, my application crashes: NSArray* toolbarItems = [NSArray arrayWithObjects:flexibleSpace,nil]; self.toolbarItems = toolbarItems; Does anyone know how I can dynamically alter the toolbar on the iPhone? Thanks!

  • What regular expression(s) would I use to remove escaped html from large sets of data.

    - by Elizabeth Buckwalter
    Our database is filled with articles retrieved from RSS feeds. I was unsure of what data I would be getting, and how much filtering was already setup (WP-O-Matic Wordpress plugin using the SimplePie library). This plugin does some basic encoding before insertion using Wordpress's built in post insert function which also does some filtering. I've figured out most of the filters before insertion, but now I have whacko data that I need to remove. This is an example of whacko data that I have data in one field which the content I want in the front, but this part removed which is at the end: <img src="http://feeds.feedburner.com/~ff/SoundOnTheSound?i=xFxEpT2Add0:xFbIkwGc-fk:V_sGLiPBpWU" border="0"></img> <img src="http://feeds.feedburner.com/~ff/SoundOnTheSound?d=qj6IDK7rITs" border="0"></img> &lt;img src=&quot;http://feeds.feedburner.com/~ff/SoundOnTheSound?i=xFxEpT2Add0:xFbIkwGc-fk:D7DqB2pKExk&quot; Notice how some of the images are escape and some aren't. I believe this has to do with the last part being cut off so as to be unrecognizable as an html tag, which then caused it to be html endcoded. Another field has only this which is now filtered before insertion, but I have to get rid of the others: &lt;img src=&quot;http://farm3.static.flickr.com/2183/2289902369_1d95bcdb85.jpg&quot; alt=&quot;post_img&quot; width=&quot;80&quot; (all examples are on one line, but broken up for readability) Question: What is the best way to work with the above escaped html (or portion of an html tag)? I can do it in Perl, PHP, SQL, Ruby, and even Python. I believe Perl to be the best at text parsing, so that's why I used the Perl tag. And PHP times out on large database operations, so that's pretty much out unless I wanted to do batch processing and what not. PS One of the nice things about using Wordpress's insert post function, is that if you use php's strip_tags function to strip out all html, insert post function will insert <p> at the paragraph points. Let me know if there's anything more that I can answer. Some article that didn't quite answer my questions. (http://stackoverflow.com/questions/2016751/remove-text-from-within-a-database-text-field) (http://stackoverflow.com/questions/462831/regular-expression-to-escape-html-ampersands-while-respecting-cdata)

  • jQuery, Animate opacity to 1 then remove the opacity property to make it better looking on IE

    - by Emily
    Hi everyone, I tried the jQuery fadeIn animation in all browsers and it work good, but not that much on IE. the Alpha png images are so creepy after appending the CSS opacity, but i have an idea and i don't know how to implement it using jQuery. The idea is to fadeIn the element and when the animation is finished it will automatically remove the opacity property in order to make the picture quality better. How to do that? Note: i'm using Animate and not FadeIn. Thanks

  • How do I remove/delete/expire a cookie immediately?

    - by dsimard
    I want to remove a cookie I set. If I do this by giving it a expiration date sometime in the past it gets marked as "expires: at end of session". I've noticed that other sites manage to delete the cookie immediately somehow. For example when you logout here on stackoverflow the "user" cookie disappears right away. How?

  • How do you remove functionality from a program in ruby?

    - by Andrew Grimm
    You have some code you want to remove associated with an obsolete piece of functionality from a ruby project. How do ensure that you get rid of all of the code? Some guidelines that usually help in refactoring ruby apply, but there are added challenges because having code that isn't being called by anything won't break any unit tests.

  • How can I deny users to add/modify/remove printers to cups ?

    - by ajcaruana
    Hi, I am using Mac OS X 10.6. I wrote a program which will add and remove printers to a CUPS server using libcups. It works, but now I am considering the security aspects. This program takes a user name and password to authenticate on the CUPS server. Whatever user name and password I use, it works as long as it is valid on the system. How do I restrict access to only a specific user ? Regards Alan

  • How to remove/hide <div></div> tags only without the content?

    - by candies
    For example I have: <div id ="test">[the content here]</div> The content within the div tags will appear after I called the id of div using ajax. This is the code: function dinamic(add) { var kode = add.value; if (!kode) return; xmlhttp2.open('get', '../template/get_id.php?kode='+kode, true); xmlhttp2.onreadystatechange = function() { if ((xmlhttp2.readyState == 4) && (xmlhttp2.status == 200)) { var add = document.getElementById("test"); add.innerHTML = xmlhttp2.responseText; } return false; } xmlhttp2.send(null); } So it will appear <div id="test">A</div> I'd like to put the content of div - A into mysql query. $test = $_GET['test']; $query = "select * from example where category='$test'"; I've tried to make variable $test of the div id to get the content but result of the query in category is none. I tried again, I put the div in to the query $query = "select * from example where category='<div id=\"test\">A</div>'"; Yes, It works. But when I did query on navicat, no results I got because there's spaces between A that is <div> and </div>. How to remove/hide the div tags only so its only appear the content? > $query = "select * from example where category='A'"; < Edit: If I echo the query on firefox browser will say "$query = "select * from example where category='[space]A[space]'";" And look at the bug(I use firebug), it will say "$query = "select * from example where category='<div id="test">A</div>'";" So my guessing why can't get result after query on navicat is there's spaces between A([space]A[space]), just have no idea how to remove/hide the div tags, I want to get this result only "$query = "select * from example where category='A'";" Thanks.
