  • Catch database exception in Kohana

    - by danilo
    I'm using Kohana 2. I would like to catch a database exception to prevent an error page when no connection to the server can be established. The error displayed is system/libraries/drivers/Database/Mysql.php [61]: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 110 The database server is not reachable at all at this point. I'm doing this from a model. I tried both public function __construct() { // load database library into $this->db try { parent::__construct(); } catch (Exception $e) { die('Database error occured'); } } as well as try { $hoststatus = $this->db->query('SELECT x FROM y WHERE z;'); } catch (Exception $e) { die('Database error occured'); } ...but none of them seemed to work. It seems as if no exception gets passed on from the main model. Is there another way to catch the database error and use my own error handling?

  • MooTools Fx.Slide throwing this.element is null

    - by Brant
    The following code is throwing the error "this.element is null". However, the wid_cont is definitely grabbing an element. window.addEvent('domready',function(){ var min = $(document.body).getElements('a.widget_minimize'); min.addEvent('click', function(event){ event.stop(); //var box = ; var wid_cont = ($(this).getParents('.widget_box').getElement('.widget_box_content_cont')); var myVerticalSlide = new Fx.Slide(wid_cont); myVerticalSlide.slideOut(); } ); }); It's moo tools 1.2.4 and has the fx.slide included....

  • Reinforcement learning And POMDP

    - by Betamoo
    I am trying to use Multi-Layer NN to implement probability function in Partially Observable Markov Process.. I thought inputs to the NN would be: current state, selected action, result state; The output is a probability in [0,1] (prob. that performing selected action on current state will lead to result state) In training, I fed the inputs stated before, into the NN, and I taught it the output=1.0 for each case that already occurred. The problem : For nearly all test case the output probability is near 0.95.. no output was under 0.9 ! Even for nearly impossible results, it gave that high prob. PS:I think this is because I taught it happened cases only, but not un-happened ones.. But I can not at each step in the episode teach it the output=0.0 for every un-happened action! Any suggestions how to over come this problem? Or may be another way to use NN or to implement prob function? Thanks

  • Dynamically changing Wordpress permalinks

    - by conrad
    i am trying to write a plugin which rewrites "post_link", "page_link", "category_link", "tag_link" with an action hook on wordpress. it's similar to this: add_action("post_link", "the_rewrite_function"); function the_rewrite_function($link) { ... return $new_link; } for example the permalink to the post is: http://www.example.com/2010/11/11/the-post-name/ i am changing it with the function to: http://www.example.com/2010/11/11/the-awesome-post-name/ of course when i do this the new permalink is going to 404 (as expected) what can i do to make the new permalink go to the original and working one? Please consider this: it should work on any permalink structure so a permalink structure spesific solution won't do any good. i need to solve this inside the plugin. thanks!

  • Zend_Auth / Zend_Session error and storing objects in Auth Storage

    - by Martin
    Hi All, I have been having a bit of a problem with Zend_Auth and keep getting an error within my Acl. Within my Login Controller I setup my Zend_Auth storage as follows $auth = Zend_Auth::getInstance(); $result = $auth->authenticate($adapter); if ($result->isValid()) { $userId = $adapter->getResultRowObject(array('user_id'), null)->user_id; $user = new User_Model_User; $users = new User_Model_UserMapper; $users->find($userId, $user); $auth->getStorage()->write( $user ); } This seems to work well and I am able to use the object stored in the Zend_Auth storage within View Helpers without any problems. The problem that I seem to be having is when I try to use this within my Acl, below is a snippet from my Acl, as soon as it gets to the if($auth->hasIdentity()) { line I get the exception detailed further down. The $user->getUserLevel() is a methord within the User Model that allows me to convert the user_level_id that is stored in the database to a meaning full name. I am assuming that the auto loader sees these kind of methords and tries to load all the classes that would be required. When looking at the exception it appears to be struggling to find the class as it is stored in a module, I have the Auto Loader Name Space setup in my application.ini. Could anyone help with resolving this? class App_Controller_Plugin_Acl extends Zend_Controller_Plugin_Abstract { protected $_roleName; public function __construct() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $user = $auth->getIdentity(); $this->_roleName = strtolower($user->getUserLevel()); } else { $this->_roleName = 'guest'; } } } Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start() - \Web\library\Zend\Loader.php(Line:146): Error #2 include_once() [&lt;a href='function.include'&gt;function.include&lt;/a&gt;]: Failed opening 'Menu\Model\UserLevel.php' for inclusion (include_path='\Web\application/../library;\Web\library;.;C:\php5\pear') Array' in \Web\library\Zend\Session.php:493 Stack trace: #0 \Web\library\Zend\Session\Namespace.php(143): Zend_Session::start(true) #1 \Web\library\Zend\Auth\Storage\Session.php(87): Zend_Session_Namespace-&gt;__construct('Zend_Auth') #2 \Web\library\Zend\Auth.php(91): Zend_Auth_Storage_Session-&gt;__construct() #3 \Web\library\Zend\A in \Web\library\Zend\Session.php on line 493 Thanks, Martin

  • Only perform jquery effects/operations on certain pages

    - by Galen
    Up until now i've been dropping all my jquery code right inside the document.ready function. I'm thinking that for certain situations this isnt the best way to go. for example: If i want an animation to perform when a certain page loads what is the best way to go about that. $(document).ready(function() { $("#element_1").fadeIn(); $("#element_2").delay('100').fadeIn(); $("#element_3").delay('200').fadeIn(); }); If this is right inside of document.ready then every time ANY page loads it's going to check each line and look for that element. What is the best way to tell jquery to only perform a chunk of code on a certain page to avoid this issue.

  • Unchecked_Conversion in ada

    - by maddy
    Hi all, Can anyone please make me clear about the use of unchecked conversion in ada language.I had tried the pdf and net but all doesnt give me a clear picture to me. Now i have a small piece of code shown below: subtype Element4_Range is integer range 1..4; subtype Element3_Range is integer range 1..3; subtype Myarr_Range is integer range 1..10; type Myarr3_Type is array (Myarr_Range) of Element3_Range; type Myarr4_Type is array (Myarr_Range) of Element4_Range; Myarr3 : Myarr3_Type; Myarr4 : Myarr4_Type := (1,2,3,3,1,3,2,1,2,1); Count_1 : Integer := 0; Count_2 : Integer := 0; Count_3 : Integer := 0; *function To_Myarr3 is new Unchecked_Conversion(Myarr4_type,Myarr3_type);* Now my doubt here is what does the function Myarr3 exactly do? Thanks and regards maddy

  • Typescript + requirejs: How to handle circular dependencies?

    - by Aymeric Gaurat-Apelli
    I am in the process of porting my JS+requirejs code to typescript+requirejs. One scenario I haven't found how to handle is circular dependencies. Require.js returns undefined on modules that are also dependent on the current and to solve this problem you can do: MyClass.js define(["Modules/dataModel"], function(dataModel){ return function(){ dataModel = require("Modules/dataModel"); ... } }); Now in typescript, I have: MyClass.ts import dataModel = require("Modules/dataModel"); class MyClass { dataModel: any; constructor(){ this.dataModel = require("Modules/dataModel"); // <- this kind of works but I lose typechecking ... } } How to call require a second time and yet keep the type checking benefits of typescript? dataModel is a module { ... }

  • C++ Win32 Unhandled Exception Handler

    - by uray
    currently I used SetUnhandledExceptionFilter() to provide callback to get information when an unhandled exception was occurred, that callback will provides me with EXCEPTION_RECORD which provides ExceptionAddress. [1]what is actually ExceptionAddress is? does it the address of function / code that gives exception, or the memory address that some function tried to access? [2]is there any better mechanism that could give me better information when unhandled exception occured? (I can't use debug mode or add any code that affect runtime performance, since crash is rare and only on release build when code run as fast as possible) [3]is there any way for me to get several callstack address when unhandled exception occured. [4]suppose ExceptionAddress has address A, and I have DLL X loaded and executed at base address A-x, and some other DLL Y at A+y, is it good to assume that crash was PROBABLY caused by code on DLL X?

  • Python key word arguments

    - by pythonic metaphor
    I have several layers of function calls, passing around a common dictionary of key word arguments: def func1(**qwargs): func2(**qwargs) func3(**qwargs) I would like to supply some default arguments in some of the subsequent function calls, something like this: def func1(**qwargs): func2(arg = qwargs.get("arg", default), **qwargs) func3(**qwargs) The problem with this approach is that if arg is inside qwargs, a TypeError is raised with "got multiple values for keyword argument". I don't want to set qwargs["arg"] to default, because then func3 gets this argument without warrant. I could make a copy.copy of the qwargs and set "arg" in the copy, but qwargs could have large data structures in it and I don't want to copy them (maybe copy.copy wouldn't, only copy.deepcopy?). What's the pythonic thing to do here?

  • How would you organize this Javascript?

    - by Anurag
    How do you usually organize complex web applications that are extremely rich on the client side. I have created a contrived example to indicate the kind of mess it's easy to get into if things are not managed well for big apps. Feel free to modify/extend this example as you wish - http://jsfiddle.net/NHyLC/1/ The example basically mirrors part of the comment posting on SO, and follows the following rules: Must have 15 characters minimum, after multiple spaces are trimmed out to one. If Add Comment is clicked, but the size is less than 15 after removing multiple spaces, then show a popup with the error. Indicate amount of characters remaining and summarize with color coding. Gray indicates a small comment, brown indicates a medium comment, orange a large comment, and red a comment overflow. One comment can only be submitted every 15 seconds. If comment is submitted too soon, show a popup with appropriate error message. A couple of issues I noticed with this example. This should ideally be a widget or some sort of packaged functionality. Things like a comment per 15 seconds, and minimum 15 character comment belong to some application wide policies rather than being embedded inside each widget. Too many hard-coded values. No code organization. Model, Views, Controllers are all bundled together. Not that MVC is the only approach for organizing rich client side web applications, but there is none in this example. How would you go about cleaning this up? Applying a little MVC/MVP along the way? Here's some of the relevant functions, but it will make more sense if you saw the entire code on jsfiddle: /** * Handle comment change. * Update character count. * Indicate progress */ function handleCommentUpdate(comment) { var status = $('.comment-status'); status.text(getStatusText(comment)); status.removeClass('mild spicy hot sizzling'); status.addClass(getStatusClass(comment)); } /** * Is the comment valid for submission */ function commentSubmittable(comment) { var notTooSoon = !isTooSoon(); var notEmpty = !isEmpty(comment); var hasEnoughCharacters = !isTooShort(comment); return notTooSoon && notEmpty && hasEnoughCharacters; } // submit comment $('.add-comment').click(function() { var comment = $('.comment-box').val(); // submit comment, fake ajax call if(commentSubmittable(comment)) { .. } // show a popup if comment is mostly spaces if(isTooShort(comment)) { if(comment.length < 15) { // blink status message } else { popup("Comment must be at least 15 characters in length."); } } // show a popup is comment submitted too soon else if(isTooSoon()) { popup("Only 1 comment allowed per 15 seconds."); } });

    Hi, All i want is to pass a HTML-Form (DOM object) from javascript to Actionscript. i saw this article on the net and tried a similar code.

  • md5 hash for file without File Attributes

    - by Glennular
    Using the following code to compute MD5 hashs of files: Private _MD5Hash As String Dim md5 As New System.Security.Cryptography.MD5CryptoServiceProvider Dim md5hash() As Byte md5hash = md5.ComputeHash(Me._BinaryData) Me._MD5Hash = ByteArrayToString(md5hash) Private Function ByteArrayToString(ByVal arrInput() As Byte) As String Dim sb As New System.Text.StringBuilder(arrInput.Length * 2) For i As Integer = 0 To arrInput.Length - 1 sb.Append(arrInput(i).ToString("X2")) Next Return sb.ToString().ToLower End Function We are getting different hashes depending on the create-date and modify-date of the file. We are storing the hash and the binary file in a SQL DB. This works fine when we upload the same instance of a file. But when we save a new instance of the file from the DB (with today's date as the create/modify) on the file-system and then check the new hash versus the MD5 stored in the DB they do not match, and therefor fail a duplicate check. How can we check for a file hash excluding the file attributes? or is there a different issue here?

  • CodeIgniter - Post multiple arrays to controller

    - by Bobe
    I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

  • jquery ajax error cannot find url outside of debug mode

    - by John Orlandella Jr.
    I inherited some code two weeks ago that is using the jquery.ajax method to connect to a .NET web service. Here is the piece of code give me the trouble... if (MSCTour.AppSettings.OFFLINE !== 'TRUE') { $.ajax({ url: url, data: json, type: "POST", contentType: "application/json", timeout: 10000, dataType: "json", // not "json" we'll parse success: function(res){ if (!callback) { return; } /* // *** Use json library so we can fix up MS AJAX dates */ var result = ""; if (res !== "") { try { result = $.evalJSON(res); } catch (e) { result = {}; bare = true; } } /* // *** Bare message IS result */ if (bare) { callback(result); return; } /* // *** Wrapped message contains top level object node // *** strip it off */ for (var property in result) { callback(result[property]); break; } }, error: function(xhr,status,error){ if (status === 'parsererror') {} else {return error;} }, complete: function(res, status){ if (callback) { if ((status != 'success' && status != 'error') || status === 'parsererror' || (status === 'timeout' && res !== '')) { try { result = $.secureEvalJSON(res); } catch (e) { result = {}; bare = true; } callback(res); } } return; } }); } The url variable at this point equals /testsite/service.svc/GetItems Now here is where my problem lies... When running this site out of debug mode through visual studio I am not having any problem connecting to the database through the web service and seeing all my data, for both viewing and updating. When I go through the normal web server for the same site, on the same page, no data is showing up. When I put a break on the error portion of the code above in firebug this is information I am getting in the image linked below. link text I am getting what appears to be a 404 error, but when I look on the server all of the files are in the right place... coupled with the fact that it works when in debug mode, I think I am slowly going crazy staring at these same lines of code trying to find the needle in the haystack. Any help or just a direction to look in would be greatly appreciated.

  • css transition initial value

I would like to show the submenu when hovering over e.g. Google link and other will appear after 300ms. So, I need to prevent loading submenu when the user just quickly hover over it and not stay on hover link for at least 300ms. Then I need to stop executing code (or slide up) when he leaves the link. Because if he go over and back and over and back a copule of times he stop doing hovering anfd the code is still executing itself how many times he had hover over the link. I need somehow prevent this to happen. EDIT: I need to solve this without plugins like hoverIntent etc. if possible, just plain javascript and jQuery

  • _heapwalk reports _HEAPBADNODE, causes breakpoint or loops endlessly

    - by Stefan Hubert
    I use _heapwalk to gather statistics about the Process' standard heap. Under certain circumstances i observe unexpected behaviours like: _HEAPBADNODE is returned some breakpoint is triggered inside _heapwalk, telling me the heap might got corrupted access violation inside _heapWalk. I saw different behaviours on different Computers. On one Windows XP 32 bit machine everything looked fine, whereas on two Windows XP 64 bit machines i saw the mentioned symptoms. I saw this behaviour only if LowFragmentationHeap was enabled. I played around a bit. I walked the heap several times right one after another inside my program. First time doing nothing in between the subsequent calls to _heapWalk (everything fine). Then again, this time doing some stuff (for gathering statistics) in between two subsequent calls to _heapWalk. Depending upon what I did there, I sometimes got the described symptoms. Here finally a question: What exactly is safe and what is not safe to do in between two subsequent calls to _heapWalk during a complete heap walk run? Naturally, i shall not manipulate the heap. Therefore i doublechecked that i don't call new and delete. However, my observation is that function calls with some parameter passing causes my heap walk run to fail already. I subsequently added function calls and increasing number of parameters passed to these. My feeling was two function calls with two paramters being passed did not work anymore. However I would like to know why. Any ideas why this does not happen on some machines? Any ideas why this only happens if LowFragmentationHeap is enabled? Sample Code finally: #include <malloc.h> void staticMethodB( int a, int b ) { } void staticMethodA( int a, int b, int c) { staticMethodB( 3, 6); return; } ... _HEAPINFO hinfo; hinfo._pentry = NULL; while( ( heapstatus = _heapwalk( &hinfo ) ) == _HEAPOK ) { //doing nothing here works fine //however if i call functions here with parameters, this causes //_HEAPBADNODE or something else staticMethodA( 3,4,5); } switch( heapstatus ) { ... case _HEAPBADNODE: assert( false ); /*ERROR - bad node in heap */ break; ...

  • javascript problems when generating html reports from within java

    - by posdef
    Hi, I have been working on a Java project in which the reports will be generated in HTML, so I am implementing methods for creating these reports. One important functionality is to be able to have as much info as possible in the tables, but still not clutter too much. In other words the details should be available if the user wishes to take a look at them but not necessarily visible by default. I have done some searching and testing and found an interesting template for hiding/showing content with the use of CSS and javascript, the problem is that when I try the resultant html page the scripts dont work. I am not sure if it's due a problem in Java or in the javascript itself. I have compared the html code that java produces to the source where I found the template, they seem to match pretty well. Below are bits of my java code that generates the javascript and the content, i would greatly appreciate if anyone can point out the possible reasons for this problem: //goes to head private void addShowHideScript() throws IOException{ StringBuilder sb = new StringBuilder(); sb.append("<script type=\"text/javascript\" language=\"JavaScript\">\n"); sb.append("<!--function HideContent(d) {\n"); sb.append("document.getElementById(d).style.display=\"none\";}\n"); sb.append("function ShowContent(d) {\n"); sb.append("document.getElementById(d).style.display=\"block\";}\n"); sb.append("function ReverseDisplay(d) {\n"); sb.append("if(document.getElementById(d).style.display==\"none\")\n"); sb.append("{ document.getElementById(d).style.display=\"block\"; }\n"); sb.append("else { document.getElementById(d).style.display=\"none\"; }\n}\n"); sb.append("//--></script>\n"); out.write(sb.toString()); out.newLine(); } // body private String linkShowHideContent(String pathname, String divname){ StringBuilder sb = new StringBuilder(); sb.append("<a href=\"javascript:ReverseDisplay('"); sb.append(divname); sb.append("')\">"); sb.append(pathname); sb.append("</a>"); return sb.toString(); } // content out.write(linkShowHideContent("hidden content", "ex")); out.write("<div id=\"ex\" style=\"display:block;\">"); out.write("<p>Content goes here.</p></div>");
