    - by user187580
    Hi, I have some xml data and I am trying to access some elements. The structure of data is as below (using print_r($data)). I can get $data->{'parent'}->title, it works but if I try to get value of href using $data->{'parent'}->link[0]->{'@attributes'}->href .. it doesnt work .. any ideas? Thanks SimpleXMLElement Object ( [@attributes] => Array ( [children] => 29 [modules] => 0 ) [title] => Test title [link] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [href] => data.php?id=2322 [rel] => self [type] => application/xml ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [href] => data.php?id=2342 [rel] => alternate [type] => text/html ) ) ) [parent] => SimpleXMLElement Object ( [@attributes] => Array ( [children] => 6 [modules] => 0 ) [title] => Top [link] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [href] => /data.php?id=5763 [rel] => self [type] => application/xml ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [href] => /data.php?id=2342 [rel] => alternate [type] => text/html ) ) ) ) )

  • Route URL laravel 4

    - by nabil l.
    How can I do this in Laravel 4 URL::route('auth.reset', array('kh34KHh4K342')) Instead of http://domain.tld/auth/reset?kh34KHh4K342 I want to get this : http://domain.tld/auth/reset/kh34KHh4K342 EDIT This my routes.php : The problem is because I have two routes with the same name? How do you explain that ? Should i set a different name event is the same kind, and different methods // Set locale $locale = Request::segment(1); if(in_array($locale, Config::get('app.languages'))) { \App::setLocale($locale); } else { $locale = null; } Route::group( array( 'prefix' => $locale ), function () { Route::get('/'), array( 'uses' => 'HomeController@getIndex', 'as' => '/' )); // Auth Route::group( array( 'prefix' => 'auth' ), function () { // Login Route::get( 'login', array( 'before' => 'guest', 'uses' => 'UserController@getLogin', 'as' => 'auth.login' ) ); Route::post( 'login', array( 'before' => 'guest|csrf', 'uses' => 'UserController@postLogin', 'as' => 'auth.login' ) ); Route::get( 'reset/{$token}', array( 'uses' => 'UserController@getReset', 'as' => 'auth.reset' ) ); Route::post( 'reset', array( 'uses' => 'UserController@postReset', 'as' => 'auth.reset' ) ); } );

  • How do I measure the size of a TextBlock in WPF before it is rendered?

    - by Scott Whitlock
    I have a WPF DataTemplate with two TextBlock controls (stacked) and then some other elements underneath. Due to some complicated layout code, I need to know the height of the two TextBlock elements so that I can draw some fancy connector lines, and line up other controls, etc. If I know the text that's going into the TextBlocks, and I know the font, etc., is there some way I can compute or measure the height of these TextBlocks without actually rendering them?

  • JarEntry.getSize() is returning -1 when the jar files is opened as InputStream from URL

    - by Reshma Donthireddy
    I am trying to read file from the JarInputStream and the size of file is returning -1. I am accessing Jar file from the URL as a inputStream. URLConnection con = url.openConnection(); JarInputStream jis = new JarInputStream(con.getInputStream()); JarEntry je = null; while ((je = jis.getNextJarEntry()) != null) { htSizes.put(je.getName(), new Integer((int) je.getSize())); if (je.isDirectory()) { continue; } int size = (int) je.getSize(); // -1 means unknown size. if (size == -1) { size = ((Integer) htSizes.get(je.getName())).intValue(); } byte[] b = new byte[(int) size]; int rb = 0; int chunk = 0; while (((int) size - rb) > 0) { chunk = jis.read(b, rb, (int) size - rb); if (chunk == -1) { break; } rb += chunk; } // add to internal resource hashtable htJarContents.put(je.getName(), baos.toByteArray()); }

  • Time taken for memcpy decreases after certain point

    - by tss
    I ve a code which increases the size of the memory(identified by a pointer) exponentially. Instead of realloc, I use malloc followed by memcpy.. Something like this.. int size=5,newsize; int *c = malloc(size*sizeof(int)); int *temp; while(1) { newsize=2*size; //begin time temp=malloc(newsize*sizeof(int)); memcpy(temp,c,size*sizeof(int)); //end time //print time in mili seconds c=temp; size=newsize; } Thus the number of bytes getting copied is increasing exponentially. The time required for this task also increases almost linearly with the increase in size. However after certain point, the time taken abruptly reduces to a very small value and then remains constant. I recorded time for similar code, copyin data(Of my own type) 5 -> 10 - 2 ms 10 -> 20 - 2 ms . . 2560 -> 5120 - 5 ms . . 20480 -> 40960 - 30 ms 40960 -> 91920 - 58 ms 367680 -> 735360 - 2 ms 735360 -> 1470720 - 2 ms 1470720 -> 2941440 - 2 ms What is the reason for this drop in time ? Does a more optimal memcpy method get called when the size is large ?

  • problem with a very simple tile based game

    - by newbieguy
    Hello, I am trying to create a pacman-like game. I have an array that looks like this: array: 1111111111111 1000000000001 1111110111111 1000000000001 1111111111111 1 = Wall, 0 = Empty space I use this array to draw tiles that are 16x16 in size. The Game character is 32x32. Initially I represented the character's position in array indexes, [1,1] etc. I would update his position if array[character.new_y][charater.new_x] == 0 Then I translated these array coordinates to pixels, [y*16, x*16] to draw him. He was lining up nicely, wouldn't go into walls, but I noticed that since I was updating him by 16 pixels each, he was moving very fast. I decided to do it in reverse, to store the game character's position in pixels instead, so that he could use less than 16 pixels per move. I thought that a simple if statement such as this: if array[(character.new_pixel_y)/16][(character.new_pixel_x)/16] == 0 would prevent him from going into walls, but unfortunately he eats a bit of the bottom and right side walls. Any ideas how would I properly translate pixel position to the array indexes? I guess this is something simple, but I really can't figure it out :(

  • Debugging instance of another thread altering my data

    - by Mick
    I have a huge global array of structures. Some regions of the array are tied to individual threads and those threads can modify their regions of the array without having to use critical sections. But there is one special region of the array which all threads may have access to. The code that accesses these parts of the array needs to carefully use critical sections (each array element has its own critical section) to prevent any possibility of two threads writing to the structure simultaneously. Now I have a mysterious bug I am trying to chase, it is occurring unpredictably and very infrequently. It seems that one of the structures is being filled with some incorrect number. One obvious explanation is that another thread has accidentally been allowed to set this number when it should be excluded from doing so. Unfortunately it seems close to impossible to track this bug. The array element in which the bad data appears is different each time. What I would love to be able to do is set some kind of trap for the bug as follows: I would enter a critical section for array element N, then I know that no other thread should be able to touch the data, then (until I exit the critical section) set some kind of flag to a debugging tool saying "if any other thread attempts to change the data here please break and show me the offending patch of source code"... but I suspect no such tool exists... or does it? Or is there some completely different debugging methodology that I should be employing.

  • Set Mime_type validation in Symfony

    - by Ngu Soon Hui
    I want to make sure that during file upload time, only the file of the format jpeg, png and gif are allowed. So the "File of type:" below in the screenshot must show jpeg, png and gif: I did the following for my validator in Symfony: $this->setValidator ( 'upload your filehere', new sfValidatorFile ( array ( 'required'=>true, 'mime_types' => array ('image/jpeg, image/png, image/gif' ) ) , array( 'mime_types'=> 'only jpeg' ) ) ); but when I click on the upload button, the files are not filtered accordingly; what did I do wrong? I also try $this->setValidator ( 'upload your filehere', new sfValidatorFile ( array ( 'required'=>true, 'mime_types' => 'image/jpeg, image/png, image/gif' ) , array( 'mime_types'=> 'only jpeg' ) ) ); But it doesn't work, too. I tried the following in my form class, but unfortunately it doesn't work as well: <?php class UploadCaseForm extends sfForm { public function configure() { $this->setWidgets ( array ('Documents' => new sfWidgetFormInputFile ( ) ) ); $this->widgetSchema->setNameFormat ( 'UploadCase[%s]' ); $this->validatorSchema ['Documents'] = new sfValidatorFile ( array ('mime_types' => 'web_images' ), array ('invalid' => 'Invalid file.', 'required' => 'Select a file to upload.', 'mime_types' => 'The file must be of JPEG, PNG or GIF format.' ) ); } } ?> Here's the action code: public function executeIndex(sfWebRequest $request) { $this->form = new UploadCaseForm ( ); if ($this->getRequest ()->getMethod () == sfRequest::POST) { var_dump($request->getParameter('UploadCase')); } } Edit: The accepted answer is the answer, as far as the server side validation goes. If anyone wants a client side validation, i.e., filtering the type of file that can be uploaded even before the operation hits server, then maybe there is no reliable way to do it, because of browser's constraint.

  • how to Clean up(destructor) a dynamic Array of pointers??

  • in c# ,one array of class and two connected instance of it why ?

    - by Al0NE
    Hi I wrote the code below : 1. MyClass[] origArr=new MyClass[3]; 2. MyClass[] arr1; 3. // filled the array with objects and did some work on it . 4. dgv_1.DataSource=origArr; 5. 6. // Here is the problem : 7. arr1=origArr; 8. // do some work on arr1 ... 9. dgv_2.DataSource=arr1; For some reason the data in 'origArr' changed when data in 'arr1' change ... I thought that maybe this happened because 'origArr' and 'arr1' are pointers referring to the same object so I changed line '7' to : 7. origArr.CopyTo(arr1,0); but it didn't work ... what can i do to make the pointers referring to different objects?

  • Generating an NSDictionary from an SQL statement.

    - by Ed Wist
    I am trying to generate an NSDictonary that can be used to populate a listview with data I retrieved from an SQL statement. when I go to create an array and add them it adds the arrays for ALL my keys and not just for the current key. I've tried a removeAllObjects on the array but for some reason that destroys ALL my data that I already put in the dictionary. //open the database if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { const char *sql = "select alphaID, word from words order by word"; sqlite3_stmt *selectStatement; //prepare the select statement int returnValue = sqlite3_prepare_v2(database, sql, -1, &selectStatement, NULL); if(returnValue == SQLITE_OK) { NSMutableArray *NameArray = [[NSMutableArray alloc] init]; NSString *alphaTemp = [[NSString alloc] init]; //loop all the rows returned by the query. while(sqlite3_step(selectStatement) == SQLITE_ROW) { NSString *currentAlpha = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 1)]; NSString *definitionName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)]; if (alphaTemp == nil){ alphaTemp = currentAlpha; } if ([alphaTemp isEqualToString:(NSString *)currentAlpha]) { [NameArray addObject:definitionName]; } else if (alphaTemp != (NSString *)currentAlpha) { [self.words setObject:NameArray forKey:currentAlpha]; [NameArray removeAllObjects]; [NameArray addObject:definitionName]; } } } The Statement above adds all the "keys" but then removes all the array elements for all keys. if I take out the removeAllKeys it adds ALL the array elements for ALL keys. I don't want this I want it to add the array elements FOR the specific key then move on to the next key. in the end I want a NSDictonary with A (array) Alpha (string) Apple (string) B (array) Beta (string) Ball (string) C (array) Code (string) ...

  • Use variables to decide which object in an array gets an attribute?

    - by DavidR
    I have a web app which has two text areas. When one text area receives a mousedown event, a variable "side" is set, either "left" or "right." When a user selects some text in a text area, three strings are made. One for the text before the beginning of the selection, the selection itself, and the text after the selection to the end. A function is set to return these like this: return { head: head_text, tail: tail_text, sel: sel_text, side: text_side } Now, I have created an array, and I want it to appear in such a way that we get, text.left({"head":"four score", "selection":"and seven", "tail":"years ago."}) I am assuming I would do this by text.side = getSelection(), but how do I get it to evaluate the variable "side" instead of thinking of it as an object within "text"? EDIT: Ok, just to clarify, I might be completely wrong in my ideas in how this works, but here it goes. I want to make it so that a function can look at "text" see within text two objects, "left" and "right," and then evaluate the head, sel, and tail of each object. Would it be easier for me to use two objects?

  • How to reduce size of html rendered from ASP.net ?

    - by Rbacarin
    I'm developing a newsletter in asp.net that will be send to a large quantity of users, so each kilobyte that I can reduce will help a lot in the use of bandwidth consumption, what I do until know is write the aspx excluding some spaces between tags, and before render, i've renamed some controls ids to "-" to save more space. So now, the file has 50kb. I need a file with 25 Kb. Can anyone teach me any other way do save more space ? ps.: I Use 3 divs with some data, and 2 repeaters, one inside other, to generate a table with some data for me. thanks in advance

  • Ruby - Nokogiri - Parsing XML from memory and putting all same name node values into an array.

    - by r3nrut
    I have an XML I'm trying to parse from memory and get the status of each of my heart beat tests using Nokogiri. Here is the solution I have... xml = <a:HBeat> <a:ElapsedTime>3 ms</a:ElapsedTime> <a:Name>Service 1</a:Name> <a:Status>true</a:Status> </a:HBeat> <a:HBeat> <a:ElapsedTime>4 ms</a:ElapsedTime> <a:Name>Service 2</a:Name> <a:Status>true</a:Status> </a:HBeat> <a:HBeat> I have tried using both css and xpath to pull back the value for each Status and put it into an array. Code is below: doc = Nokogiri::XML.parse(xml) #service_state = doc.css("a:HBeat, a:Status", 'a' => 'http://schemas.datacontract.org/2004/07/OpenAPI.Entity').map {|node| node.children.text} service_state = doc.xpath("//*[@a:Status]", 'a' => 'http://schemas.datacontract.org/2004/07/OpenAPI.Entity').map(&:text) Both will return service_state = []. Any thoughts or recommendations? Also, consider that I have almost identical xml for another test and I used the following snippet of code which does exactly what I wanted but for some reason isn't working with the xml that contains namespaces. service_state = doc.css("HBeat Status").map(&:text) Thanks!

  • How to properly cast a global memory array using the uint4 vector in CUDA to increase memory throughput?

    - by charis
    There are generally two techniques to increase the memory throughput of the global memory on a CUDA kernel; memory accesses coalescence and accessing words of at least 4 bytes. With the first technique accesses to the same memory segment by threads of the same half-warp are coalesced to fewer transactions while be accessing words of at least 4 bytes this memory segment is effectively increased from 32 bytes to 128. To access 16-byte instead of 1-byte words when there are unsigned chars stored in the global memory, the uint4 vector is commonly used by casting the memory array to uint4: uint4 *text4 = ( uint4 * ) d_text; var = text4[i]; In order to extract the 16 chars from var, i am currently using bitwise operations. For example: s_array[j * 16 + 0] = var.x & 0x000000FF; s_array[j * 16 + 1] = (var.x >> 8) & 0x000000FF; s_array[j * 16 + 2] = (var.x >> 16) & 0x000000FF; s_array[j * 16 + 3] = (var.x >> 24) & 0x000000FF; My question is, is it possible to recast var (or for that matter *text4) to unsigned char in order to avoid the additional overhead of the bitwise operations?

  • How can I theme custom form(drupal 6.x)

    - by Andrew
    DRUPAL 6.X I have this custom form constructor inside my custom module which is invoke through ajax request. I’m attempting to theme this form with the template file reside in my theme directory. For that matter, I’ve registered my theme inside template.php file which reside in my theme folder. Here’s how this file looks – function my_theme() { return array( 'searchdb' => array( 'arguments' => array('form' => NULL), 'template' => 'searchform', ) ); } And the following is the excerpt of module code – function test_menu() { $my_form['searchdb'] = array( 'title' => 'Search db', 'page callback' => 'get_form', 'page arguments' => array(0), 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function get_form($formtype){ switch($formtype){ case 'searchdb' : echo drupal_get_form('searchdb'); break; } } function searchdb(){ $form['customer_name'] = array( '#type' => 'textfield', '#title' => t('Customer Name'), '#size' => 50, '#attributes' => array('class' => 'name-textbox'), ); return $form; } As you can imagine, this is not working at all. Just to test if my theme is even registered, I’ve also tested with theme function but, it’s not called. I've checked template file name and form-id(through the outputted html source) and everything seems ok. I would be glad if anyone could point me to the right direction.
