• UIPickerView didSelectRow delay

  - by Rob Bonner

  Hello all, I have a UIPickerView implemented in one of my pages that depends on the didSelectRow delegate method. An odd behavior I have noticed is when the user moves a wheel and leaves it between selections, then the wheel will move very slowly to the closest selection. The didSelectRow event will not fire until this is complete, sometimes 3 seconds later. Is there a way to speed this up, or detect when the wheel is being moved, so I can freeze my interface during this time?

• When is a Google Maps API key required?

  - by Thomas

  Recently Google changed it's policy on the use API keys. You're now supposed to no longer need an API key to place Google Maps on your website. And this worked perfectly. But now I have this map (without API key) running on my localhost, which works fine. But as soon as I place it online, I get a popup saying that I need another API key. And on another page on that website, Google Maps does work. Could it maybe have something to do with that the map that doesn't work have a lot (30+) of markers on it? Actually using an API key wouldn't be a very nice solution to me, as this is part of a Wordpress plugin used on many websites.

• Tootip steals mouse click

  - by deerchao

  I'm writing a custom TreeView from ScrollableControl. I decided to show tooltips when mouse is hover nodes with text too long to display. I find out when tooltips are shown, user would not be able to click the node to select it, because (I think) he's clicking the tooltip window, not my control. Is there any easy solutions? As I can see System.Windows.Forms.TreeView don't have this problem. Thanks!

• Is there any real alternative to GeoServer as dynamic map generator in Java ?

  - by Costi Ciudatu

  I'm looking for the most suitable tool for generating dynamic geographical maps in Java (with styles based on custom business data: colors, labels etc. will be dynamically set). After some searching, only GeoServer (and the underlying GeoTools library) seems to fit. Although I'm really happy with this solution, I'm afraid I might miss something and make some decision based on incomplete input. Any suggestion ? Any viable alternative to compare against ?

• PHP float bug: PHP Hangs On Numeric Value

  - by jeroen

  I just read an interesting article about php hanging on certain float numbers, see The Register and Exploring Binary. I never explicitly use floats, I use number_format() to clean my input and display for example prices. Also, as far as I am aware, all input from for example forms are strings until I tell them otherwise so I am supposing that this problem does not affect me. Am I right, or do I need to check for example Wordpress and Squirrelmail installations on my server to see if they cast anything to float? Or better, grep all php files on my servers for float?

• PHP Session Class and $_SESSION Array

  - by Gianluca Bargelli

  Hello, i've implemented this custom PHP Session Class for storing sessions into a MySQL database: class Session { private $_session; public $maxTime; private $database; public function __construct(mysqli $database) { $this->database=$database; $this->maxTime['access'] = time(); $this->maxTime['gc'] = get_cfg_var('session.gc_maxlifetime'); session_set_save_handler(array($this,'_open'), array($this,'_close'), array($this,'_read'), array($this,'_write'), array($this,'_destroy'), array($this,'_clean') ); register_shutdown_function('session_write_close'); session_start();//SESSION START } public function _open() { return true; } public function _close() { $this->_clean($this->maxTime['gc']); } public function _read($id) { $getData= $this->database->prepare("SELECT data FROM Sessions AS Session WHERE Session.id = ?"); $getData->bind_param('s',$id); $getData->execute(); $allData= $getData->fetch(); $totalData = count($allData); $hasData=(bool) $totalData >=1; return $hasData ? $allData['data'] : ''; } public function _write($id, $data) { $getData = $this->database->prepare("REPLACE INTO Sessions VALUES (?, ?, ?)"); $getData->bind_param('sss', $id, $this->maxTime['access'], $data); return $getData->execute(); } public function _destroy($id) { $getData=$this->database->prepare("DELETE FROM Sessions WHERE id = ?"); $getData->bind_param('S', $id); return $getData->execute(); } public function _clean($max) { $old=($this->maxTime['access'] - $max); $getData = $this->database->prepare("DELETE FROM Sessions WHERE access < ?"); $getData->bind_param('s', $old); return $getData->execute(); } } It works well but i don't really know how to properly access the $_SESSION array: For example: $db=new DBClass();//This is a custom database class $session=new Session($db->getConnection()); if (isset($_SESSION['user'])) { echo($_SESSION['user']);//THIS IS NEVER EXECUTED! } else { $_SESSION['user']="test"; Echo("Session created!"); } At every page refresh it seems that $_SESSION['user'] is somehow "resetted", what methods can i apply to prevent such behaviour?

• Is HTTP 404 appropriate for out of range page number on paged content?

  - by WooYek

  I have a site that is mainly showing a paged list of content (articles, data element's, etc.), and I'm wondering about returning HTTP 404 when user navigates outside of the available list range. Some sites just display "No results/Page number out of range" and some return additionally return HTTP 404 status. What's your take on that, and why? UPDATE It's not and api response. This question is in regard to user viewed pages that among other things show a list/table in the main area.
