  • Google Spreadsheet API problem: memory exceeded

    - by Robbert
    Hi guys, Don't know if anyone has experience with the Google Spreadsheets API or the Zend_GData classes but it's worth a go: When I try to insert a value in a 750 row spreadsheet, it takes ages and then throws an error that my memory limit (which is 128 MB!) was exceeded. I also got this when querying all records of this spreadsheet but this I can imaging because it's quite a lot of data. But why does this happen when inserting a row? That's not too complex, is it? Here's the code I used: public function insertIntoSpreadsheet($username, $password, $spreadSheetId, $data = array()) { $service = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME; $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $service); $client->setConfig(array( 'timeout' => 240 )); $service = new Zend_Gdata_Spreadsheets($client); if (count($data) == 0) { die("No valid data"); } try { $newEntry = $service->insertRow($data, $spreadSheetId); return true; } catch (Exception $e) { return false; } }

  • F# Inline Function Specialization

    - by Ben
    Hi, My current project involves lexing and parsing script code, and as such I'm using fslex and fsyacc. Fslex LexBuffers can come in either LexBuffer<char> and LexBuffer<byte> varieties, and I'd like to have the option to use both. In order to user both, I need a lexeme function of type ^buf - string. Thus far, my attempts at specialization have looked like: let inline lexeme (lexbuf: ^buf) : ^buf -> string where ^buf : (member Lexeme: char array) = new System.String(lexbuf.Lexeme) let inline lexeme (lexbuf: ^buf) : ^buf -> string where ^buf : (member Lexeme: byte array) = System.Text.Encoding.UTF8.GetString(lexbuf.Lexeme) I'm getting a type error stating that the function body should be of type ^buf -> string, but the inferred type is just string. Clearly, I'm doing something (majorly?) wrong. Is what I'm attempting even possible in F#? If so, can someone point me to the proper path? Thanks!

  • php funciton problem

    - by Holian
    Hello, i have this little script, which should ping the IPs in the host_to_ping array. This php is called with JS in the index.html. But somethin' wrong, 'coz the $rval is always 1 (which mean the host is unreachable). But i know that the first two host is alive. So i print the $res variable, and i see the message: Need to give the IP. I dont understand why dont replace the $host variable to the actual IP address in the function. <?php function ping($host) { exec(sprintf('ping -n 4', escapeshellarg($host)), $res, $rval); print_r($res); return $rval === 0; } $hosts_to_ping = array('10.54.23.254', '10.22.23.254', '10.23.66.134'); ?> <ul> <?php foreach ($hosts_to_ping as $host): ?> <li> <?php echo $host; ?> <?php $up = ping($host); ?> (<img src="<?php echo $up ? 'on' : 'off'; ?>" alt="<?php echo $up ? 'up' : 'down'; ?>">) </li> <?php endforeach; ?> </ul>

  • Twitter O-Auth Callback url

    - by jtymann
    I am having a problem with Twitter's oauth authentication and using a callback url. I am coding in php and using the sample code referenced by the twitter wiki, http://github.com/abraham/twitteroauth I got that code, and tried a simple test and it worked nicely. However I want to programatically specify the callback url, and the example did not support that. So I quickly modified the getRequestToken() method to take in a parameter and now it looks like this: function getRequestToken($params = array()) { $r = $this->oAuthRequest($this->requestTokenURL(), $params); $token = $this->oAuthParseResponse($r); $this->token = new OAuthConsumer($token['oauth_token'], $token['oauth_token_secret']); return $token; } and my call looks like this $tok = $to->getRequestToken(array('oauth_callback' => 'http://127.0.0.1/twitter_prompt/index.php')); This is the only change I made, and the redirect works like a charm, however I am getting an error when I then try and use my newly granted access to try and make a call. I get a "Could not authenticate you" error. Also the application never actually gets added to the users authorized connections. Now I read the specs and I thought all I had to do was specify the parameter when getting the request token. Could someone a little more seasoned in oauth and twitter possibly give me a hand? Thank You

  • HTML Form HIdden Fields added with Javascript not POSTing

    - by dscher
    I have a form where the user can enter a link, click the "add link" button, and that link is then(via jQuery) added to the form as a hidden field. The problem is it's not POSTing when I submit the form. It's really starting to confound me. The thing is that if I hardcode a hidden field into the form, it is posted, but my function isn't working for some reason. The hidden field DOES get added to my form as I can see with Firebug but it's just not being sent with the POST data. Just to note, I'm using an array in Javascript to hold the elements until the form is submitted which also posts them visibly for the user to see what they've added. I'm using [] notation on the "name" field of the element because I want the links to feed into an array in PHP. Here is the link creation which is being appended to my form: function make_hidden_element_tag(item_type, item_content, item_id) { return '<input type="hidden" name="' + item_type + '[]" id="hidden_link_' + item_id + '" value="' + item_content + '"/>'; Does anyone have an idea why this might not be posting. As stated above, any hard-coded tags that are nearly identical to the above works fine, it's just that this tag isn't working. Here is how I'm adding the tag to the form with jQUery: $('#link_td').append( make_hidden_element_tag('links', link, link_array.length - 1)); I'm using the Kohana 3 framework, although I'm not sure that has any bearing on this because it's not really doing anything from the time the HTML is added to the page and the submit button is pressed.

  • [MySQL/PHP] Avoid using RAND()

    - by Andrew Ellis
    So... I have never had a need to do a random SELECT on a MySQL DB until this project I'm working on. After researching it seems the general populous says that using RAND() is a bad idea. I found an article that explains how to do another type of random select. Basically, if I want to select 5 random elements, I should do the following (I'm using the Kohana framework here)? If not, what is a better solution? Thanks, Andrew <?php final class Offers extends Model { /** * Loads a random set of offers. * * @param integer $limit * @return array */ public function random_offers($limit = 5) { // Find the highest offer_id $sql = ' SELECT MAX(offer_id) AS max_offer_id FROM offers '; $max_offer_id = DB::query(Database::SELECT, $sql) ->execute($this->_db) ->get('max_offer_id'); // Check to make sure we're not trying to load more offers // than there really is... if ($max_offer_id < $limit) { $limit = $max_offer_id; } $used = array(); $ids = ''; for ($i = 0; $i < $limit; ) { $rand = mt_rand(1, $max_offer_id); if (!isset($used[$rand])) { // Flag the ID as used $used[$rand] = TRUE; // Set the ID if ($i > 0) $ids .= ','; $ids .= $rand; ++$i; } } $sql = ' SELECT offer_id, offer_name FROM offers WHERE offer_id IN(:ids) '; $offers = DB::query(Database::SELECT, $sql) ->param(':ids', $ids) ->as_object(); ->execute($this->_db); return $offers; } }

  • Getting the name of a child class in the parent class (static context)

    - by Benoit Myard
    Hi everybody, I'm building an ORM library with reuse and simplicity in mind; everything goes fine except that I got stuck by a stupid inheritance limitation. Please consider the code below: class BaseModel { /* * Return an instance of a Model from the database. */ static public function get (/* varargs */) { // 1. Notice we want an instance of User $class = get_class(parent); // value: bool(false) $class = get_class(self); // value: bool(false) $class = get_class(); // value: string(9) "BaseModel" $class = __CLASS__; // value: string(9) "BaseModel" // 2. Query the database with id $row = get_row_from_db_as_array(func_get_args()); // 3. Return the filled instance $obj = new $class(); $obj->data = $row; return $obj; } } class User extends BaseModel { protected $table = 'users'; protected $fields = array('id', 'name'); protected $primary_keys = array('id'); } class Section extends BaseModel { // [...] } $my_user = User::get(3); $my_user->name = 'Jean'; $other_user = User::get(24); $other_user->name = 'Paul'; $my_user->save(); $other_user->save(); $my_section = Section::get('apropos'); $my_section->delete(); Obviously, this is not the behavior I was expecting (although the actual behavior also makes sense).. So my question is if you guys know of a mean to get, in the parent class, the name of child class.

  • Selenium RC: How to assert an element contains text and any number of other elements?

    - by Andrew
    I am using Selenium RC and the PHPUnit Selenium Extension. I am trying to assert that a table row exists, with the content that I expect, while making it flexible enough to be reused. Thanks to this article, I figured out a way to select the table row, asserting that it contains all the text that I expect. $this->assertElementPresent("css=tr:contains(\"$text1\"):contains(\"$text2\")"); But now I would like to assert that a specific radio button appears in the table row also. Here's the element that I would like to assert that is within the table row. (I am currently asserting that it exists using XPath. I'm sure I could do the same using CSS). $this->assertElementPresent("//input[@type='radio'][@name='Contact_ID'][@value='$contactId']"); Currently I have a function that can assert that a table row exists which contains any number of texts, but I would like to add the ability to specify any number of elements and have it assert that the table row contains them. How can I achieve this? /** * Provides the ability to assert that all of the text appear in the same table row. * @param array $texts */ public function assertTextPresentInTableRow(array $texts) { $locator = 'css=tr'; foreach ($texts as $text) { $locator .= ":contains(\"$text\")"; } $this->assertElementPresent($locator); }

  • How to prevent PHP variables from being arrays?

    - by MJB
    I think that (the title) is the problem I am having. I set up a MySQL connection, I read an XML file, and then I insert those values into a table by looping through the elements. The problem is, instead of inserting only 1 record, sometimes I insert 2 or 3 or 4. It seems to depend on the previous values I have read. I think I am reinitializing the variables, but I guess I am missing something -- hopefully something simple. Here is my code. I originally had about 20 columns, but I shortened the included version to make it easier to read. $ctr = 0; $sql = "insert into csd (id,type,nickname,hostname,username,password) ". "values (?,?,?,?,?,?)"; $cur = $db->prepare($sql); for ($ctr = 0; $ctr < $expected_count; $ctr++) { list ( $lbl, $type, $nickname, $hostname, $username, $password) = ""; $bind_vars = array(); $lbl = "csd_{$ctr}"; $type = $ref->itm->csds->$lbl->type; $nickname = $ref->itm->csds->$lbl->nickname; $hostname = $ref->itm->csds->$lbl->hostname; $username = $ref->itm->csds->$lbl->username; $password = $ref->itm->csds->$lbl->password; $bind_vars = array($id,$type,$nickname,$hostname,$username,$password); $res = $db->execute($cur, $bind_vars); # this is a separate function which works, but which only # does SELECTS and cannot be the problem. I include it because I # want to count the total rows. printf ("%d CSDs on that ITEM now.\n", CountCSDs($id_to_sync)); } P.S. I also tagged this SimpleXML because that is how I am reading the file, though that code is not included above. It looks like this: $Ref = simplexml_load_file($file);

  • Wordpress: How to override all default theme CSS so your custom one is loaded the last?

    - by mickael
    I have a problem where I've been able to include a custom css in the section of my wordpress theme with the following code: function load_my_style_wp_enqueue_scripts() { wp_register_style('my_styles_css', includes_url("/css/my_styles.css")); wp_enqueue_style('my_styles_css'); } add_action('wp_enqueue_scripts','load_my_style_wp_enqueue_scripts'); But the order in the source code is as follows: <link rel='stylesheet' id='my_styles_css-css' href='http://...folderA.../my_styles.css?ver=3.1' type='text/css' media='all' /> <link rel="stylesheet" id="default-css" href="http://...folderB.../default.css" type="text/css" media="screen,projection" /> <link rel="stylesheet" id="user-css" href="http://...folderC.../user.css" type="text/css" media="screen,projection" /> I want my_styles_css to be the last file to load, overriding default and user files. I've tried to achieve this by modifying wp_enqueue_style in different ways, but without any success. I've tried: wp_enqueue_style('my_styles_css', array('default','user')); or wp_enqueue_style('my_styles_css', false, array('default','user'), '1.0', 'all'); I've seen some related questions without answer or with these last 2 methods that are still failing for me. The function above is part of a plugin that I've got enabled in my wordpress installation.

  • Find min. "join" operations for sequence

    - by utyle
    Let's say, we have a list/an array of positive integers x1, x2, ... , xn. We can do a join operation on this sequence, that means that we can replace two elements that are next to each other with one element, which is sum of these elements. For example: - array/list: [1;2;3;4;5;6] we can join 2 and 3, and replace them with 5; we can join 5 and 6, and replace them with 11; we cannot join 2 and 4; we cannot join 1 and 3 etc. Main problem is to find minimum join operations for given sequence, after which this sequence will be sorted in increasing order. Note: empty and one-element sequences are sorted in increasing order. Basic examples: for [4; 6; 5; 3; 9] solution is 1 (we join 5 and 3) for [1; 3; 6; 5] solution is also 1 (we join 6 and 5) What I am looking for, is an algorithm that solve this problem. It could be in pseudocode, C, C++, PHP, OCaml or similar (I mean: I woluld understand solution, if You wrote solution in one of these languages). I would appreciate Your help.

  • ipad full screen (1024x768) animation with around 1800 frames fps problem

    - by Muhammad Farhan
    Hi there. what i am trying to do is to play a full screen(1024x768) animation on ipad with an fps of around 20. i have got a scene with 1800 full screen frames. till now i have tried a lot of approaches but have encountered a lot of problems. my first approach was to get the texture using the following function t = [[CCTexture2D alloc] initWithImage:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"(%d)",startIndex] ofType:type]]]; give it to sprite by using setTexture method and then release the texture then create a new texture with next frame and repeat the procedure but by using this approach i only get an FPS of about 7. my second approach was to preload about 10 textures in texturecache save them in an array and give them to sprite using setTexture and on the back end i am replacing the old textures with the new texture in a thread but the problem i face is that creating new texture and adding to array takes some time and when the settexture method is called the sprite displays the old texture because the new one is not loaded yet but after some time new texture get loaded. Is there any way i can run a full screen animation on ipad at around 20 fps plesae help me out. Thanks Farhan

  • How can I free all allocated memory at once?

    - by Tommy
    Here is what I am working with: char* qdat[][NUMTBLCOLS]; char** tdat[]; char* ptr_web_data; // Loop thru each table row of the query result set for(row_index = 0; row_index < number_rows; row_index++) { // Loop thru each column of the query result set and extract the data for(col_index = 0; col_index < number_cols; col_index++) { ptr_web_data = (char*) malloc((strlen(Data) + 1) * sizeof(char)); memcpy (ptr_web_data, column_text, strlen(column_text) + 1); qdat[row_index][web_data_index] = ptr_web_data; } } tdat[row_index] = qdat[col_index]; After the data is used, the memory allocated is released one at a time using free(). for(row_index = 0; row_index < number_rows; row_index++) { // Loop thru all columns used for(col_index = 0; col_index < SARWEBTBLCOLS; col_index++) { // Free memory block pointed to by results set array free(tdat[row_index][col_index]); } } Is there a way to release all the allocated memory at once, for this array? Thank You.

  • Facebook JS API: users_getInfo() inside ifUserConnected() deadlock.

    - by serg555
    I am trying to put Facebook connect button on the site and once connected display connected username. But for some reason following code goes into some infinite loop during first connection, and then works fine unless I delete this app from my facebook profile which causes freezing again. Here is a code on FB connect button click: FB.Connect.requireSession(); Here is code directly on the page: <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript"> FB.init("123", "/xd_receiver.htm"); FB.ensureInit(function() { FB.Connect.ifUserConnected(function() { FB.Facebook.apiClient.users_getInfo(new Array(FB.Connect.get_loggedInUser()),new Array("name"), function(user, exec) { console.log("logged in:"+user[0].name); }); }, function(){ console.log("guest"); }); }); </script> If I remove FB.Facebook.apiClient.users_getInfo() it works fine, but I need to get username somehow. Any tips? Thanks.

  • How can I use JSONP to download client-side javascript objects?

    - by Alex Mcp
    I'm trying to get client-side javascript objects saved as a file locally. I'm not sure if this is possible. The basic architecture is this: Ping an external API to get back a JSON object Work client-side with that object, and eventually have a "download me" link This link sends the data to my server, which processes it and sends it back with a mime type application/json, which (should) prompt the user to download the file locally. Right now here are my pieces: Server Side Code <?php $data = array('zero', 'one', 'two', 'testing the encoding'); $json = json_encode($data); //$json = json_encode($_GET['']); //eventually I'll encode their data, but I'm testing header("Content-type: application/json"); header('Content-Disposition: attachment; filename="backup.json"'); echo $_GET['callback'] . ' (' . $json . ');'; ?> Relevant Client Side Code $("#download").click(function(){ var json = JSON.stringify(collection); //serializes their object $.ajax({ type: "GET", url: "http://www.myURL.com/api.php?callback=?", //this is the above script dataType: "jsonp", contentType: 'jsonp', data: json, success: function(data){ console.log( "Data Received: " + data[3] ); } }); return false; }); Right now when I visit the api.php site with Firefox, it prompts a download of download.json and that results in this text file, as expected: (["zero","one","two","testing the encoding"]); And when I click #download to run the AJAX call, it logs in Firebug Data Received: testing the encoding which is almost what I'd expect. I'm receiving the JSON string and serializing it, which is great. I'm missing two things: The Actual Questions What do I need to do to get the same prompt-to-download behavior that I get when I visit the page in a browser (much simpler) How do I access, server-side, the json object being sent to the server to serialize it? I don't know what index it is in the GET array (silly, I know, but I've tried almost everything)

  • Cannot set property X of undefined - programatically created element

    - by Dave
    I am working on a class to create a fairly complex custom element. I want to be able to define element attributes (mainly CSS) as I am creating the elements. I came up with the below function to quickly set attrs for me given an input array: // Sample array structure of apply_settings //var _button_div = { // syle : { // position: 'absolute', // padding : '2px', // right : 0, // top : 0 // } //}; function __apply_settings(__el,apply_settings){ try{ for(settingKey in apply_settings){ __setting = apply_settings[settingKey]; if(typeof(__setting)=='string'){ __el[settingKey] = __setting; }else{ for(i in __setting){ __el[settingKey][i] = apply_settings[settingKey][i]; } } } }catch(ex){ alert(ex + " " + __el); } } The function works fine except here: function __draw_top(){ var containerDiv = document.createElement('div'); var buttonDiv = document.createElement('div'); __apply_settings(containerDiv,this.settings.top_bar); if(global_settings.show_x) buttonDiv.appendChild(__create_img(global_settings.images.close)); containerDiv.appendChild(buttonDiv); __apply_settings(buttonDiv,this.settings.button_div); return containerDiv; } The specific section that is failing is __apply_settings(buttonDiv,this.settings.button_div); with the error "Cannot set property 'position' of undefined". So naturally, I am assuming that buttonDiv is undefined.. I put alert(ex + " " + __el); in __apply_settings() to verify what I was working with. Surprisingly enough, the element is a div. Is there any reason why this function would be working for containerDiv and not buttonDiv? Any help would be greatly appreciated :) {EDIT} http://jsfiddle.net/Us8Zw/2/

    Hi, I'm trying to create a custom form element which extends Zend_Form_Element_Text with a validator (so I don't have to keep setting up the validator when I use certain elements). Anyway, I'm having trouble passing $maxChars variable to it when I instantiate it in my Main form. I've provided my shortened code below This is my custom element below class My_Form_Custom_Element extends Zend_Form_Element_Text { public $maxChars public function init() { $this->addValidator('StringLength', true, array(0, $this->maxChars)) } public function setProperties($maxChars) { $this->maxChars= $maxChars; } } This is where I instantiate my custom form element. class My_Form_Abc extends Zend_Form { public function __construct($options = null) { parent::__construct($options); $this->setName('abc'); $customElement = new My_Form_Custom_Element('myCustomElement'); $customElement->setProperties(100); //**<----This is where i set the $maxChars** $submit = new Zend_Form_Element_Submit('submit'); $submit -> setAttrib('id', 'submitbutton'); $this->addElements(array($customElement ,$submit)); } } When I try to pass '100' using $customElement-setProperties(100) in my Form, it doesnt get passed properly to my StringLength validator. I assume it's because the validator is getting called in Init? How can I fix this?

  • Exporting WPF DataGrid to a text file in a nice looking format. Text file must be easy to read.

    - by Andrew
    Hi, Is there a simple way to export a WPF DataGrid to a text file and a .csv file? I've done some searching and can't see that there is a simple DataGrid method to do so. I have got something working (barely) by making use of the ItemsSource of the DataGrid. In my case, this is an array of structs. I do something with StreamWriters and StringBuilders (details available) and basically have: StringBuilder destination = new StringBuilder(); destination.Append(row.CreationDate); destination.Append(seperator); // seperator is '\t' or ',' for csv file destination.Append(row.ProcId); destination.Append(seperator); destination.Append(row.PartNumber); destination.Append(seperator); I do this for each struct in the array (in a loop). This works fine. The problem is that it's not easy to read the text file. The data can be of different lengths within the same column. I'd like to see something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 And of course, I get something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 It's not surprising giving that I'm using Tab delimiters, but I hope to do better. It certainly is easy to read in the DataGrid! I could of course have some logic to pad short values with spaces, but that seems quite messy. I thought there might be a better way. I also have a feeling that this is a common problem and one that has probably been solved before (hopefully within the .NET classes themselves). Thanks.

  • Dynamic select menu Rails, Javascript HABTM

    - by Jack
    Hi, I am following a tutorial in one of Ryan Bates' Railscasts here. Basically I want a form where there are 2 drop down menus, the contents of one are dependent on the other. I have Years and Courses, where Years HABMT Courses and Courses HABTM Years. In the tutorial, the javascript is as follows: var states = new Array(); <% for state in @states -%> states.push(new Array(<%= state.country_id %>, '<%=h state.name %>', <%= state.id %>)); <% end -%> function countrySelected() { country_id = $('person_country_id').getValue(); options = $('person_state_id').options; options.length = 1; states.each(function(state) { if (state[0] == country_id) { options[options.length] = new Option(state[1], state[2]); } }); if (options.length == 1) { $('state_field').hide(); } else { $('state_field').show(); } } document.observe('dom:loaded', function() { countrySelected(); $('person_country_id').observe('change', countrySelected); }); Where I guess country has many states and state belongs to country. I think what I need to do is edit the first for statement to somehow loop through all of the courses for each year_id, but don't know how to do this. Any ideas? Thanks

  • Use queried json data in a function

    - by SztupY
    I have a code similar to this: $.ajax({ success: function(data) { text = ''; for (var i = 0; i< data.length; i++) { text = text + '<a href="#" id="Data_'+ i +'">' + data[i].Name + "</a><br />"; } $("#SomeId").html(text); for (var i = 0; i< data.length; i++) { $("#Data_"+i).click(function() { alert(data[i]); RunFunction(data[i]); return false; }); } } }); This gets an array of some data in json format, then iterates through this array generating a link for each entry. Now I want to add a function for each link that will run a function that does something with this data. The problem is that the data seems to be unavailable after the ajax success function is called (although I thought that they behave like closures). What is the best way to use the queried json data later on? (I think setting it as a global variable would do the job, but I want to avoid that, mainly because this ajax request might be called multiple times) Thanks.
