• C++ toLowerCase Function won't work - Access violation

  - by misaizdaleka

  Hi, I have a simple function which takes an array of characters as an argument, and converts all the characters to lower case. However, I get a weird access violation error. Here's the code: void toLower(char *rec) { int i=0; while (rec[i]!='\0') { if (rec[i]>='A' && rec[i]<='Z') rec[i]='a'+rec[i]-'A'; //this is where I get an error - assigning the //the value to rec[i] is the problem i++; } } Can you tell me what's my mistake? Thanks

• Accessing loop iteration in a sub-function?

  - by DisgruntledGoat

  I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?

• Creating a PHP web page that enables you to reboot the server in Linux?

  - by Stuart

  I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

• Symfony form's i18n and add_empty

  - by David

  I have this widget: $this->setWidget('slug', new sfWidgetFormDoctrineChoice(array('model' => 'MyTable', 'method' => 'myMethod', 'key_method' => 'myMethod', 'add_empty' => 'Select option'))); Ok, what should I do to translate the "Select option"? I can't use the __() helper inside the form, and adding that string into my XLIFF file doesn't translate it automatically. If it can't be done, what workaround should I implement? I can't find any way, and neither can't find any tip in the official documentation. Thanks!

• Why is the GUID structure declared the way it is?

  - by alabamasucks

  In rpc.h, the GUID structure is declared as follows: typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data[8]; } GUID; I understand Data1, Data2, and Data3. They define the first, second, and third sets of hex digits when writing out a GUID (XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX). What I never understood was why the last 2 groups were declared together in the same byte array. Wouldn't this have made more sense (and been easier to code against)? typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; WORD Data4; BYTE Data5[6]; } GUID; Anyone know why it is declared this way?

• Replace strings differently depending if is enclosed in braces or not.

  - by peroyomas

  I want to replace all instances of an specific words between braces with something else, unless it is written between double braces, while it should show as is it was written with single braces without the filter. I have tried a code but only works for the first match. The rest are shown depending of the first one: $foo = 'a {bar} b {{bar}} c {bar} d'; $baz = 'Chile'; preg_match_all( '/(\{?)\{(tin)\}(\}?)/i', $foo, $matches, PREG_SET_ORDER ); if ( !empty($matches) ) { foreach ( (array) $matches as $match ) { if( empty($match[1]) && empty($match[3])) { $tull = str_replace( $match[0], $baz, $foo ); } else { $tull = str_replace( $match[0], substr($match[0], 1, -1), $foo ) ; } } } echo $tull;

• Why are configuration arrays acceptible parameters in PHP and Javascript?

  - by RenderIn

  In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

• Force memcached to write to all servers in pool

  - by Industrial

  Hi everyone, I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool. My current, untested solution is to make another instance of memcached, something like this: $cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50); foreach ($this->cluster() as $cluster) { @$this->tempMemcache = new Memcache; @$this->tempMemcache->connect($cluster['host'], $cluster['port']); @$this->tempMemcache->set($key, $value, $this->compress, $expireTime); @$this->tempMemcache->close(); } What is common sense to do in this case, when certain keys need to be stored on ALL servers for reliability?

• IndexedDB and Relationships

  - by Josh Johnson

  Can I create relationships between my object stores in IndexedDB? For example, I have two object stores: artist and album. An artist has a one-to-many relationship with an album. album.artistId relates the album to artist.id. I'm thinking along the lines of Hibernate here. I would like to do a query for artists and have the albums belonging to that artist returned as an array called artists on the album object. artist.albums = [];

• CakePHP delete() function is not working

  - by Logic Artist

  Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

• PHP object help -> unexpected T_OBJECT_OPERATOR

  - by php-b-grader

  Please help me understand: print gettype(new CustomerObject()) prints: "object" (so it is an object) BUT print gettype((new CustomerObject())->get_customer()); prints: unexpected T_OBJECT_OPERATOR If I do it over two lines it works fine $object = new Customer($order->customer_id); print gettype($object); prints: object $customer = $object->get_customer(); print gettype($customer); prints: array It appears that the lines cannot be joined into a single call. Is this correct? and what is the logic behind that?

• Is there a way to make this C# method shorter and more readable with the help of Linq?

  - by Hamish Grubijan

  The following works, but I figured - since it is all based on IEnumerable, Linq can come handy here is well. By the way, is there an equivalent to Directory.GetFiles() which would return an IEnumerable instead of the array? If it exists, then would it make the code run any faster? The last part of the question is inspired by Python language which favors lightweight generators over concrete lists. private IEnumerable<string> getFiles(string strDirectory, bool bCompressedOnly) { foreach (var strFile in Directory.GetFiles(strDirectory)) { // Don't add any existing Zip files since we don't want to delete previously compressed files. if (!bCompressedOnly || Path.GetExtension(strFile).ToLower().Equals(".zip")) { yield return strFile; } } foreach (var strDir in Directory.GetDirectories(strDirectory)) { foreach (var strFile in getFiles(strDir, bCompressedOnly)) { yield return strFile; } } }

• Why does a non-constant offsetof expression work?

  - by Chris J. Kiick

  Why does this work: #include <sys/types.h> #include <stdio.h> #include <stddef.h> typedef struct x { int a; int b[128]; } x_t; int function(int i) { size_t a; a = offsetof(x_t, b[i]); return a; } int main(int argc, char **argv) { printf("%d\n", function(atoi(argv[1]))); } If I remember the definition of offsetof correctly, it's a compile time construct. Using 'i' as the array index results in a non-constant expression. I don't understand how the compiler can evaluate the expression at compile time. Why isn't this flagged as an error?

• How to make web service methods return string value in lines format?

  - by Born To Learn

  How to make web service methods return string value in lines format? My web service method looks like this [WebMethod] public string GetSomeLines() { System.Text.StringBuilder builder = new StringBuilder(); builder.AppendLine("Line1."); builder.AppendLine("Line2."); builder.AppendLine("Line3."); return builder.ToString(); } But when I get the result from web browser or from delphi/c# consumer it will be like this: Line1. Line2. Line3. While I expect to see: Line1. Line2. Line3. I know may be returning a StringBuilder or String Array is an option here but I want to know if there is a way to make this with string result. Thanks for your help.

• using a tileset with canvas

  - by Anonymous

  Yeah so I'm lost from the get-go. Alright let's say I have a big image with every tile for a 2D top-down RPG game. They're all the same width and everything. What I don't know is how would I save every individual tile from that image to their own image data for use on the canvas? Basically I want to take a big image with all my tiles, choose squares throughout it to make images out of the tiles, and store each image as a variable in an array. So, how would I do this?

• Should Perl's opendir always return . and .. first?

  - by ojblass

  opendir MYDIR, "$dir"; my @FILES = readdir MYDIR; closedir MYDIR; It appears that 99.9 % of the time the first two entries in the array are always “.” and “..”. Later logic in the script has issues if it is not true. I ran into a case where the directory entries appeared later. Is this indicative of the file system being corrupt or something else? Is there a known order to what opendir returns?

• How to store matrix information in MySQL?

  - by dedalo

  Hi, I'm working on an application that analizes music similarity. In order to do that I proccess audio data and store the results in txt files. For each audio file I create 2 files, 1 containing and 16 values (each value can be like this:2.7000023942731723) and the other file contains 16 rows, each row containing 16 values like the one previously shown. I'd like to store the contents of these 2 file in a table of my MySQL database. My table looks like: Name varchar(100) Author varchar (100) in order to add the content of those 2 file I think I need to use the BLOB data type: file1 blob file2 blob My question is how should I store this info in the data base? I'm working with Java where I have a double array containing the 16 values (for the file1) and a matrix containing the file2 info. Should I process the values as strings and add them to the columns in my database? Thanks

• ZendFramework Zend_Form_Element_File setDestination vs rename filter

  - by bibstha

  The code says Zend_Form_element_File::setDestination() is depricated and to use the rename filter. However the rename filter is currently codes such that when path is set, only temporary name is given. Original filename is lost. <?php $file = new Zend_Form_Element_File(); $file->setDestination('/var/www/project/public'); ?> vs <?php $file = new Zend_Form_Element_File(); $file->addFilter('Rename', array('target' => '/var/www/project/public')); ?> Any solution to upload files so that it preserves original filename structure but checks for existing file and appends _1.ext or _2.ext?

• Seeking assistance with Escaping Data for MySQL queries

  - by JM4

  Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!

• why assert_equal() in Ruby on Rails sometimes seem to compare by Identity and sometimes by value?

  - by Jian Lin

  it was very weird that yesterday, I was do an integration test in Rails and assert_equal array_of_obj1, array_of_obj2 # obj1 from db, obj2 created in test and it failed. The values shown inside the array and objects were identical. If I change the test to assert array_of_obj1 == array_of_obj2 Then it will pass. But today, the first test actually passed. What reason could it be? Is assert_equal always using == or .equal? in Rails 2.2 or 2.3.5?

• Iterating through facebook comments JSON object failing

  - by user1594304

  I tried the option of students.item["http://www.myurl.com"].comments.data.length. However, the item["http://www.myurl.com"] call is not working. If I take out the URL from JSON object and write the iterator with students.comments.data, it works. Here is my code, any help highly appreciated. var students = { "http://www.myurl.com":{ "comments":{ "data" : [ { "id": "123456778", "from": { "name": "XYZ", "id": "1000005" }, "message": "Hey", "can_remove": false, "created_time": "2012-09-03T03:16:01+0000", "like_count": 0, "user_likes": false } ] } } } var i=0 var arrayObject = new Array(); alert("Parsing 2: "+students.item["http://www.myurl.com"].comments.data.length); for(i=0;i<students.item["http://www.myurl.com"].comments.data.length;i++) { alert("Parsing 1: "+i); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].id); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].message); arrayObject.push(students.item["http://www.myurl.com"].comments.data[i].created_time); }
