Hello, I don't understand the output of NSLog for the array returned by a NSFetchRequest. I'm reading my database and placing the contents in an array, looping through the array and then outputting the contents with NSLog. I don't quite understand the output in the log file. Code below: -(void)createXMLFeed{ //Fetch details from ...
I am currently developing a programming language in C, and I want to allow users to create apparently "unlimited" arrays with numerical indices without sacrificing performance in the process. For example, table [1000000000] would ideally be creatable and accessible in an instant without the memory overhead of a table of 1,000,000,000 ite...
I'm having a little trouble with an array I've defined. int[] levelData = new int[450] {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,...
Hi, how can I make this not return an error of: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING . $day[$i++] = "<tr><?php if(isset($schedule['00:00'])) { ?><td style=\"width:32px\"><?php echo $schedule['00:00'] ?></td><?php } if(isset($schedule['02:00'])) { ?><td style...
Hi, I am trying to populate a dropdown menu on an events page with a list of locations. What I wish to do is retrieve all names from a locations table, store them in an array in my event.php controller, pass this to a view which then lists all the locations in a dropdown menu. Here is the loop in my controller which retrieves the loca...
I'm not sure if the word Reorganizing is the correct term, but its the only way I can describe what I'm looking for. If I have an array of say, Cats, like so: CAT *myCats[99]; myCats[0] = new CAT; myCats[1] = new CAT; myCats[2] = new CAT; myCats[3] = new CAT; myCats[4] = new CAT; myCats[5] = new CAT; At one point in time, lets say m...
Hello, so i've got an array of numbers that i'm posting to an asp.net mvc action that has a list(of integer) parameter and it all works great. my question is this: Is it safe to assume that the list(of integer) will have the numbers in the same order as they were in the array i posted? Thanks for your time! EDIT: The data being ...
I have an object array, I know that the elements are type String, say I need to access them many times. Practice 1: access the element by array index and cast it to String every time I need it. Practice 2: create local String instances and access each of the elements once. Which will run faster? If it's on a mobile device where memor...
Hi again, I'd like to use AMFPHP and Flash Remoting to set up a system in which an array of objects on the Flash client gets checked against a mirrored array on the server. I've never used Remoting or AMF before, but I have worked on some projects that involved serialization, and I remember serializing an array of objects and arrays of...
In Perl 5.10.1: #!/usr/bin/perl my @a = (1, 2, 3); my $b = \@a; print join('', @{$b}) . "\n"; @a = (6, 7, 8); print join('', @{$b}) . "\n"; This prints 123 then 678. However, I'd like to get 123 both times (i.e. reassigning the value of @a will not change the array that $b references). How can I do this? ...
Does anyone know how to store an array in Monotouch NSUserDefaults? One possible method: NSUserDefaults.StandardUserDefaults["Array"] = new NSObject(); But how do I turn an array or list into an NSObject? ...

Let's say I have an array, and I print it: print_r($myArray); Array ( [post] => 333434kj [test] => wOVvc [tytytyty] => xyzsalasjf ) This array gets assigned to a CURL Post: curl_setopt($ch, CURLOPT_POSTFIELDS, "field1=".$f1."&field2=".$f2."&something=True"); Since "field1" is equal to "post" and $f...
Just noticed something strange and wondered if there was a reason for it. I have a grayscale image in EmguCV (.net wrapper for openCV). If this image has C channels (1 for grayscale, 3 for RGB), a width of X pixels and a height of Y pixels, the data array is consistently of the form: [Y,X+2,C] Anyone know why? ...
I'm an intermittent programmer and seem to have forgotten a lot of basics recently. I've created a class SimPars to hold several two-dimensional arrays; the one shown below is demPMFs. I'm going to pass a pointer to an instance of SimPars to other classes, and I want these classes to be able to read the arrays using SimPars accessor fun...
I'm using an array to store the names of other arrays which are dynamically generated elsewhere. I need to loop through the "names" array and access the contents of the "named" arrays. Something like this: $names = array("one", "two", "three"); $one = array("a", "b", "c"); $two = array("c", "d", "e"); $three = array("f", "g", "h"); fore...
PROBLEM I have a nested PHP array that I need to populate from flat scalar values. The problem is I cannot know ahead of time what the structure of the nested PHP array will be until I get the request to fill in the flat scalar values. EXAMPLE // example where we populate the array using standard PHP $person['contact_info']['fname']...
$arr = array(25,41,120,...36); How to group values in $arr to specified integer range $start ~ $end ? For example , if the level range is 1~5(1,2,3,4,5), how can I specify a level for each element of $arr ? The only principle is that larger value should map to larger level, and should cover the entire level range as possible. UPDAT...
I'm trying to get a constant string and index it as if it was an array of characters (square bracket syntax). When I try this code it fails on the last line. define( 'CONSTANT_STRING','0123456789abcdef'); echo CONSTANT_STRING; // Works by itself :) $string = CONSTANT_STRING; echo $string[9]; // Also works by itself. echo strlen(CONSTAN...
