  • How can I extract values out of this array?

    - by Jagira
    Array ( [status] => success [abc] => Array ( [0] => Array ( [name] => John Doe [age] => 23) [1] => Array ( [name] => John Doe_1 [age] => 23) [2] => Array ( [name] => John Doe_2 [age] => 23) ) ) When I try foreach($stories as $story){ } It returns an error.

  • Fastest way to zero out a 2d array in C?

    - by Eddy
    I want to repeatedly zero a large 2d array in C. This is what I do at the moment: for(j = 0; j < n; j++) { for(i = 0; i < n; i++) { array[i][j] = 0; } } I've tried using memset: memset(array, 0, sizeof(array)) But this only works for 1D arrays. When I printf the contents of the 2D array, the first row is zeroes, but then I got a load of random large numbers and it crashes.

  • How can we make a single dimension array to multidimensional Hierarchical ?

    - by Chetan sharma
    I have an single array of Hierarchical categories. Index of the array is the category_id like:: [8846] => Array ( [category_id] => 8846 [title] => Tsting two [description] => Tsting two [subtype] => categories [type] => object [level] => 2 [parent_category] => 8841 [tags] => new [name] => Tsting two ) each value has its parent_category value, I have around 500 elements in the array, what is the best way to make it. Process i followed: krsort categories array, so that all the child categories are at the beginning, then function makeHierarchical() { foreach($this->categories as $guid => $category) { if($category['level'] != 1) $this->multilevel_categories[$category['parent_category']][$guid] = $category; } } but this is not working, it does it only for first level. Can someone point out me the error.

  • why my array is losing it's contents when I refresh the page?

    - by Fernando SBS
    I have created an: var checkboxFarm = new Array(); then I want to record a checkbox status in that array, as there are 11 checkboxes. Button.addEventListener("click", function() { rp_farmAtivada(index); }, false); when clicked change the variable in the array: function rp_farmAtivada(index) { checkboxFarm[index] = !checkboxFarm[index]; }; but every time I refresh the page it loses all the checkboxes status and I'm aware that all that array gets the "undefined" value. the checkboxFarm array is defined in the beginning of the script, so it should have a global scope. Am I missing something?

  • How do I convert a Python list of lists of lists into a C array by using ctypes?

    - by pc05
    As seen here How do I convert a Python list into a C array by using ctypes? this code will take a python array and transform it to a C array. import ctypes arr = (ctypes.c_int * len(pyarr))(*pyarr) Which would the way of doing the same with a list of lists or a lists of lists of lists? For example, for the following variable list3d = [[[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]], [[40.0, 1.2, 6.0, 0.3], [50.0, 4.2, 0, 0]]] I have tried the following with no luck: ([[ctypes.c_double * 4] *2]*3)(*list3d) # *** TypeError: 'list' object is not callable (ctypes.c_double * 4 *2 *3)(*list3d) # *** TypeError: expected c_double_Array_4_Array_2 instance, got list Thank you! EDIT: Just to clarify, I am trying to get one object that contains the whole multidimensional array, not a list of objects. This object's reference will be an input to a C DLL that expects a 3D array.

  • How do I return the indices of a multidimensional array element in C?

    - by Eddy
    Say I have a 2D array of random boolean ones and zeroes called 'lattice', and I have a 1D array called 'list' which lists the addresses of all the zeroes in the 2D array. This is how the arrays are defined: define n 100 bool lattice[n][n]; bool *list[n*n]; After filling the lattice with ones and zeroes, I store the addresses of the zeroes in list: for(j = 0; j < n; j++) { for(i = 0; i < n; i++) { if(!lattice[i][j]) // if element = 0 { list[site_num] = &lattice[i][j]; // store address of zero site_num++; } } } How do I extract the x,y coordinates of each zero in the array? In other words, is there a way to return the indices of an array element through referring to its address?

  • How to make an mutable C array for this data type?

    - by mystify
    There's this instance variable in my objective-c class: ALuint source; I need to have an mutable array of OpenAL Sources, so in this case probably I need a mutable C-array. But how would I create one? There are many questions regarding that: 1) How to create an mutable C-array? 2) How to add something to that mutable C-array? 3) How to remove something from that mutable C-array? 4) What memory management pitfalls must I be aware of? Must i free() it in my -dealloc method? And yes, I think this is something for the nice community wiki...

  • Make an array of two.

    - by marharépa
    Hello! I'd like to make an array which tells my site's pages where to show in PHP. In $sor["site_id"] i've got two or four chars-lenght strings. example: 23, 42, 13, 1 In my other array (called to $pages_show) i want to give all the site_ids to an other id. $parancs="SELECT * FROM pages ORDER BY id"; $eredmeny=mysql_query($parancs) or die("Hibás SQL:".$parancs); while($sor=mysql_fetch_array($eredmeny)) { $pages[]=array( "id"=>$sor["id"], "name"=>$sor["name"], "title"=>$sor["title"], "description"=>$sor["description"], "keywords"=>$sor["keywords"] ); // this makes my pages array with the information about that page. $shower = explode(", ",$sor["site_id"]); // this is explode my site_id $pages_show[]=array( "id"=>$sor["id"], "where"=>$shower //to 'where' i want to put all the explode's elements one-by-one, to get the result like down ); This script gives me the following result: Array (3) 0 => Array (2) id => "29" where => Array (2) 0 => "17" 1 => "16" 1 => Array (2) id => "30" where => Array (1) 0 => "17" 2 => Array (2) id => "31" where => Array (1) 0 => "17" But in this case I'd like to be this: Array (4) 0 => Array (2) id => "29" where => "17" 1 => Array (2) id => "29" where => "16" 2 => Array (2) id => "30" where => "17" 3 => Array (2) id => "31" where => "17" Thanks for your help.

  • Problems with 3D Array for Voxel Data

    - by Sean M.
    I'm trying to implement a voxel engine in C++ using OpenGL, and I've been working on the rendering of the world. In order to render, I have a 3D array of uint16's that hold that id of the block at the point. I also have a 3D array of uint8's that I am using to store the visibility data for that point, where each bit represents if a face is visible. I have it so the blocks render and all of the proper faces are hidden if needed, but all of the blocks are offset by a power of 2 from where they are stored in the array. So the block at [0][0][0] is rendered at (0, 0, 0), and the block at 11 is rendered at (1, 1, 1), but the block at [2][2][2] is rendered at (4, 4, 4) and the block at [3][3][3] is rendered at (8, 8, 8), and so on and so forth. This is the result of drawing the above situation: I'm still a little new to the more advanced concepts of C++, like triple pointers, which I'm using for the 3D array, so I think the error is somewhere in there. This is the code for creating the arrays: uint16*** _blockData; //Contains a 3D array of uint16s that are the ids of the blocks in the region uint8*** _visibilityData; //Contains a 3D array of bytes that hold the visibility data for the faces //Allocate memory for the world data _blockData = new uint16**[REGION_DIM]; for (int i = 0; i < REGION_DIM; i++) { _blockData[i] = new uint16*[REGION_DIM]; for (int j = 0; j < REGION_DIM; j++) _blockData[i][j] = new uint16[REGION_DIM]; } //Allocate memory for the visibility _visibilityData = new uint8**[REGION_DIM]; for (int i = 0; i < REGION_DIM; i++) { _visibilityData[i] = new uint8*[REGION_DIM]; for (int j = 0; j < REGION_DIM; j++) _visibilityData[i][j] = new uint8[REGION_DIM]; } Here is the code used to create the block mesh for the region: //Check if the positive x face is visible, this happens for every face //Block::VERT_X_POS is just an array of non-transformed cube verts for one face //These checks are in a triple loop, which goes over every place in the array if (_visibilityData[x][y][z] & 0x01 > 0) { _vertexData->AddData(&(translateVertices(Block::VERT_X_POS, x, y, z)[0]), sizeof(Block::VERT_X_POS)); } //This is a seperate method, not in the loop glm::vec3* translateVertices(const glm::vec3 data[], uint16 x, uint16 y, uint16 z) { glm::vec3* copy = new glm::vec3[6]; memcpy(&copy, &data, sizeof(data)); for(int i = 0; i < 6; i++) copy[i] += glm::vec3(x, -y, z); //Make +y go down instead return copy; } I cannot see where the blocks may be getting offset by more than they should be, and certainly not why the offsets are a power of 2. Any help is greatly appreciated. Thanks.

  • dequeueReusableCell:withIdentifier: returns a cell even if it is not there?

    - by lostInTransit
    Hi I am using SDK 3.2 to create an iPad application. In my table I have 2 kinds of rows, one with a custom accessory view and another without any. I use two different cell identifiers for creating these. The first cell is created properly (dequeueReusable... returns a nil and the cell is initialized). But when a call is made to dequeueReusable.. with the other cell identifier, the cell is not nil (it should be because this is the first time the identifier is being used) An even stranger part is that when I use this cell to set the textLabel's text, it returns an EXC_BAD_ACCESS. So 2 questions Why is dequeueReusable... returning a cell when there is no cell created using the said identifier Even if it does return a cell, why is access to textLabel causing a crash? Thanks.

  • php getting unique values of a multidimensional array

    - by Mark
    I have an array like this: $a = array ( 0 => array ( 'value' => 'America', ), 1 => array ( 'value' => 'England', ), 2 => array ( 'value' => 'Australia', ), 3 => array ( 'value' => 'America', ), 4 => array ( 'value' => 'England', ), 5 => array ( 'value' => 'Canada', ), ) How can I remove the duplicate values so that I get this: $a = array ( 0 => array ( 'value' => 'America', ), 1 => array ( 'value' => 'England', ), 2 => array ( 'value' => 'Australia', ), 4 => array ( 'value' => 'Canada', ), ) I tried using array_unique, but that doesn't work due to this array being multidimensional, I think. Thanks!

  • Too Many Different Cell Formats

    - by Craig
    I have a massive file with 10 sheets recreated from scratch, 12 sheets updated, 5 sheets loaded with raw data, and 7 sheets that are used by the macros for the report. I have recently added a new sheet and am running into the Excel "Too many different cell formats" problem. I have read some of the google search results and they say I should simplify the formatting, but I don't even know how I got up to 4000 distinct cell formats, let alone how much I'm using which ones, so I can remove some. It is also popping up some times the file is run, but not all, until such time as it comes up, and then it happens every time it is run. Since the macro is doing so much of the work, including creating the 10 sheets from scratch, I am not sure what to do. Does anyone know of a Macro I could run to get a listing of all the cell formats and how many cells are using them? Does anyone know of a program they trust to help remove excess cell formats? Thanks, Craig

  • Binding to NSTextField Cell not working, edited value resets to default

    - by cygnus6320
    I'm working on a Core Data document application that dynamically creates NSTableColumns. The data cell type may be a checkbox, slider, etc. Programmatically binding to all cell types works, except for NSTextFieldCell. All NSTextFieldCells fail to bind, and after editing they return to their default value. This happens no matter if they're binding to a string, a number (with an NSNumberFormatter applied), or a date (NSDateFormatter applied). I'm using the following format to do all bindings: NSDictionary *textFieldOpts = [NSDictionary dictionaryWithObjectsAndKeys:@"YES", NSContinuouslyUpdatesValueBindingOption, @"YES", NSValidatesImmediatelyBindingOption, nil]; [aCell bind:@"value" toObject:[[entryAC arrangedObjects] objectAtIndex:0] withKeyPath:@"numberData" options:textFieldOpts]; Again, these statements work if the cell type is anything but an NSTextFieldCell. I threw in an observeValueForKeyPath method to log when the value changes... and for other cell types (NSSliderCell for instance) I can see the value changing, but with the NSTextFieldCell, it never, ever updates. Help!

  • iPhone Table View Cell Image: Working on simulator, not showing on real device

    - by Graeme
    Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. At first 3 did, but then I "cleaned headers" and now none appear. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

  • wsdl return an array of complex types

    - by Anand
    hi, I have defined a web service that will return the data from my mysql data base. I have written the web service in php. Now I have defined a complex type as follows: $server->wsdl->addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' => array('name' => 'category_parent_id', 'type' => 'xsd:int'), 'category_child_id' => array('name' => 'category_child_id', 'type' => 'xsd:int'), 'category_list' => array('name' => 'category_list', 'type' => 'xsd:int') ) ); The above complex type is a row in a table in my database. Now my function must send an array of these rows so how do I achieve the same My code is as follows: require_once('./nusoap/nusoap.php'); $server = new soap_server; $server-configureWSDL('productwsdl', 'urn:productwsdl'); // Register the data structures used by the service $server-wsdl-addComplexType( 'Category', 'complexType', 'struct', 'all', '', array( 'category_parent_id' = array('name' = 'category_parent_id', 'type' = 'xsd:int'), 'category_child_id' = array('name' = 'category_child_id', 'type' = 'xsd:int'), 'category_list' = array('name' = 'category_list', 'type' = 'xsd:int') ) ); $server-register('getaproduct', // method name array(), // input parameters //array('return' = array('result' = 'tns:Category')), // output parameters array('return' = 'tns:Category'), // output parameters 'urn:productwsdl', // namespace 'urn:productwsdl#getaproduct', // soapaction 'rpc', // style 'encoded', // use 'Get the product categories' // documentation ); function getaproduct() { $conn = mysql_connect('localhost','root',''); mysql_select_db('sssl', $conn); $sql = "SELECT * FROM jos_vm_category_xref"; $q = mysql_query($sql); while($r = mysql_fetch_array($q)) { $items[] = array('category_parent_id'=$r['category_parent_id'], 'category_child_id'=$r['category_child_id'], 'category_list'=$r['category_list']); } return $items; } // Use the request to (try to) invoke the service $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ''; $server-service($HTTP_RAW_POST_DATA);

  • Getting Tap/Touch Position when selecting a TableView cell

    - by Omer
    Hi, hope to get some help here because this is something that really makes me mad... I have a view with a tableView, and when I tap a cell I want to present a popOver window pointing the arrow to the cell I tapped. the things that I think I need is: 1- the position of the cell in the screen (not in the view, because on large tables the Y value of the cell's rect could be grater than screen hight) or 2- a CGPoint or something similar that represents the point in the screen I tapped. I can't figured this out, and makes me really mad!!! Any help will very very very very usefull. Have a nice day.

  • UITableView Cell IndexPath

    - by Reonarudo
    Hello, Can anyone tell me how can I get a cell IndexPath? I was saving the IndexPath in the tableView: cellForRowAtIndexPath: method but this only loads when the cell is viewed and I need to know its index path on the viewDidLoad method. this resulted in a null value because as I said it only loads its value after the cell was viewed once. Thank you. EDIT The intention is being able to jump to a specific cell that has its specific number but its not linear with the sections and rows count.

  • Add blank cell at end of UITable

    - by Michael
    I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!
