• JComboBox to string

  - by gabrielle fregil

  I have a String array of names, and then I added it into an editable JComboBox. The user can either pick his/her name from the choices or just input his/her name if not in the choices. How do I put the user input into a new string variable? String [] chooseName = { Mark, John, Allison, Jessica }; JComboBox combo = new JComboBox (chooseName); combo.setEditable(true); String chosenName = /* how do i place what the user inputed here? */

• Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

  - by John Himmelman

  My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

• Choosing randomly all the elements in the the list just once

  - by Dalek

  How is it possible to randomly choose a number from a list with n elements, n time without picking the same element of the list twice. I wrote a code to choose the sequence number of the elements in the list but it is slow: >>>redshift=np.array([0.92,0.17,0.51,1.33,....,0.41,0.82]) >>>redshift.shape (1225,) exclude=[] k=0 ng=1225 while (k < ng): flag1=0 sq=random.randint(0, ng) while (flag1<1): if sq in exclude: flag1=1 sq=random.randint(0, ng) else: print sq exclude.append(sq) flag1=0 z=redshift[sq] k+=1 It doesn't choose all the sequence number of elements in the list.

• Polymorphic behavior not being implemented

  - by Garrett A. Hughes

  The last two lines of this code illustrate the problem: the compiler works when I use the reference to the object, but not when I assign the reference to an array element. The rest of the code is in the same package in separate files. BioStudent and ChemStudent are separate classes, as well as Student. package pkgPoly; public class Poly { public static void main(String[] arg) { Student[] stud = new Student[3]; // create a biology student BioStudent s1 = new BioStudent("Tom"); // create a chemistry student ChemStudent s2 = new ChemStudent("Dick"); // fill the student body with studs stud[0] = s0; stud[1] = s1; // compiler complains that it can't find symbol getMajor on next line System.out.println("major: " + stud[0].getMajor() ); // doesn't compile; System.out.println("major: " + s0.getMajor() ); // works: compiles and runs correctly } }

• 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?

• 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 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?

• AS3 Passing data between objects/classes

  - by 1337holiday

  So i a building a categorized menu of different foods. I have a class for "categories" (buttons) which essentially will return a string "salads", "drinks", etc. I now have another class "menuItems" for items within categories and this handles sizes such as "small", "med", "large", etc. My problem now is that when i return "salads", i want to invoke an array which contains all the elements of salads, send it to menuItems which will populate the menu. So far i have both the category objects and the menu object setup. I just cant seem to be able to send the data that the category object is returning and pass it to the menu object. Both of which are added to the stage as shown below: If there was a way that i could say add all these classes to one class so that they can talk to each other that would be great but i dont know how to do this. Been stuck for hours, please any help is greatly appreciated.

• 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?

• 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!

• 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?
