  • Google Maps: Multimarker not working

    - by HyperDevil
    Hi, I want to plot several markers on my map. Found some code on the internet, for that user it worked. The array is generated by PHP, example: var ships = [['61','10.2']['60.5','10.1']]; My Javascript: var map; function load(ships) { initialize(); createShips(ships); } function initialize() { //build the map var myLatlng = new google.maps.LatLng(63.65,10.65); var myOptions = { zoom: 9, center: myLatlng, mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } function createShips(ships) { for (var i = 0; i < ships.length; i++) { new google.maps.Marker({ position: new google.maps.LatLng(ships[i][0], ships[i][1]), map: map, title: ships[i][0] }); } } My html function to start the map is: body onload="load()" The map seems to appear, but no markers :(

  • Why does strlen not working for me?

    - by tushar
    char p[4]={'h','g','y'}; cout<<strlen(p); This code prints 3. char p[3]={'h','g','y'}; cout<<strlen(p); This prints 8. char p[]={'h','g','y'}; cout<<strlen(p); This again prints 8. Please help me as I can't figure out why three different values are printed by changing the size of the array.

  • hook_form for multiple content types defined by the same module

    - by pao13gate
    A new module 'foo' implements foo_node_info() where one or more new content types can be defined. If foo_node_info() defines two content types, namely a content type 'footypea' and a content type 'footypeb', how does one go about implementing hook_form() (what should the name of the "hook" be?) to configure each node's editing form? In the drupal example, the name of the new content type is the same as the module name. What happens in the above described example where two new content types are defined by the module? Should the implemented hook_form() function be of the form: footypea_form() and footypeb_form() ? (this doesn't seem to work) Or should you implement a single foo_form() function and within this create and return an array $form with elements $form['footypea'] and $form['footypeb'] that are in turn arrays of the individual form field definitions?

  • decode mysql query before returning it to view

    - by stormdrain
    I'm running a query to mysql that returns encrypted data. I'd like, if possible, to decode the results before sending it to the view. It seems like better form to handle the decoding in the controller (or even the model) rather than inside the view. I can't seem to wrap my head around how to do it, though. I was thinking I could iterate through the object, decodode it, and push it to another array that would be sent to the view. Problem with this is I won't know (and need to keep) the indexes of the query. So the query might return something like: [id] => 742 [client_id] => 000105 [last] => dNXcw6mQPaGQ4rXfgIGJMq1pZ1dYAim0 [first] => dDF7VoO37qdtYoYKfp1ena5mjBXXU0K3dDlcq1ssSvCgpOx75y0A== [middle] =>iXy6OWa48kCamViDZFv++K6okIkalC0am3OMPcBwK8sA== [phone] => eRY3zBhAw2H8tKE Any ideas?

  • Default values for Content Taxonomy fields in Drupal

    - by lazysoundsystem
    I'm trying to set the default value for a Content Taxonomy field in a hook_form_alter, but can't pin down the necessary format. I've tried this and many variations: foreach (element_children($form) as $child) { // Set $default_value. if ($form[$child]['tids']) { // This, for Content Taxonomy fields, isn't working: $form[$child]['tids']['#default_value'] = array('value' => $default_value); dsm($form[$child]['tids']['#default_value']); } else { // This, for other fields, is working: $form[$child][0]['#default_value']['value'] = $default_value; } } Can anyone tell me what I'm missing?

  • Internal scala compilation. Working with interactive.Global

    - by scout
    I am trying to retrieve the AST from scala souce file. I have simplified the code (only relevant code) to following. trait GetAST { val settings = new Settings val global = new Global(settings, new ConsoleReporter(settings)) def getSt = "hello" //global.typedTree(src, true) } object Tre extends GetAST { def main(args:Array[String]) { println(getSt.getClass) println("exiting program") } } The above code compiles fine and runs fine. But the problem is the program does not exit. The prompt is not displayed after printing "exiting program". I have to use ^c to exit. Any idea what the problem might be

  • what are the recent dataStructure and algorithms that one should know?

    - by Shamik
    Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.

  • JButtons re-enable themselves after being disabled

    - by Anarchist
    I have an array of JButtons which form a keypad interface. After six numbers are entered I want to disable the keypad so that no further numbers can be entered by the user. I have written the code and the buttons do disable until the mouse hovers above any of them, then the buttons seem to re-enable themselves and run actionEvents added to them. The full code is available here. Possible things that I think are wrong. There is some sort of MouseListener which is ignoring when I set button.setEnabled(false); I haven't separated attributes from the buildGUI(); correctly, I only did this anyway so that the inner class could access them. Possibly something to do with the gridLayout as disabling the buttons seems to work for my services JPanel buttons.

I have yet to find anything in the Book or by search. So any help is appreciated. Thanks.

  • Python OpenGL Can't Redraw Scene

    - by RobbR
    I'm getting started with OpenGL and shaders using GLUT and PyOpenGL. I can draw a basic scene but for some reason I can't get it to update. E.g. any changes I make during idle(), display(), or reshape() are not reflected. Here are the methods: def display(self): glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT ) glMatrixMode(GL_MODELVIEW) glLoadIdentity() glUseProgram(self.shader_program) self.m_vbo.bind() glEnableClientState( GL_VERTEX_ARRAY ) glVertexPointerf(self.m_vbo) glDrawArrays(GL_TRIANGLES, 0, len(self.m_vbo)) glutSwapBuffers() glutReportErrors() def idle(self): test_change += .1 self.m_vbo = vbo.VBO( array([ [ test_change, 1, 0 ], # triangle [ -1,-1, 0 ], [ 1,-1, 0 ], [ 2,-1, 0 ], # square [ 4,-1, 0 ], [ 4, 1, 0 ], [ 2,-1, 0 ], [ 4, 1, 0 ], [ 2, 1, 0 ], ],'f') ) glutPostRedisplay() def begin(self): glutInit() glutInitWindowSize(400, 400) glutCreateWindow("Simple OpenGL") glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB) glutDisplayFunc(self.display) glutReshapeFunc(self.reshape) glutMouseFunc(self.mouse) glutMotionFunc(self.motion) glutIdleFunc(self.idle) self.define_shaders() glutMainLoop() I'd like to implement a time step in idle() but even basic changes to the vertices or tranlastions and rotations on the MODELVIEW matrix don't display. It just puts up the initial state and does not update. Am I missing something?

  • Nhibernate Bind

    - by user329983
    I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

  • Are PDO prepared statements sufficient to prevent SQL injection?

    - by Mark Biek
    Let's say I have code like this: $dbh = new PDO("blahblah"); $stmt = $dbh->prepare('SELECT * FROM users where username = :username'); $stmt->execute( array(':username' => $_REQUEST['username']) ); The PDO documentation says The parameters to prepared statements don't need to be quoted; the driver handles it for you. Is that truly all I need to do to avoid SQL injections? Is it really that easy? You can assume MySQL if it makes a difference. Also, I'm really only curious about the use of prepared statements against SQL injection. In this context, I don't care about XSS or other possible vulnerabilities.

  • How to implement HeightMap smoothing using Thrust

    - by igal k
    I'm trying to implement height map smoothing using Thrust. Let's say I have a big array ( around 1 million floats). A known graphics algorithm to implement the above problem is to calculate the average around a given cell. If for example I need to calculate the value at a given cell[i,j] what I will basically do is: cell[i,j] = cell[i-1,j-1] + cell[i-1,j] + cell[i-1,j+1] + cell[i,j-1] + cell[i,j+1] + cell[i+1,j -1] + cell[i+1,j] + cell[i+1,j+1] cell[i,j] /=9 That's the CPU code. Is there a way to implement it using thrust? I know that I could use the transform algorithm. But I'm not sure it's correct to access different cells which are occupied but different threads (banks conflicts and so on).

  • ajax Post data missing with tinyMCE on Firefox

    - by Freeman
    I have a problem with my form when I try to submit with ajax. I am using Malsup Form plugin for Jquery but also using tinyMCE editor. When I submit the form and check the $_POST array, there is no data from the textarea. I have tried to use the triggerSave() function but to no avail. Everything is working well in IE. // These options are common and will be used for many form submissions var options = { target: '#notice', // target element(s) to be updated with server response dataType:'html', resetForm:true, beforeSubmit: function(){tinyMCE.triggerSave(false,true); }, success:function(msg){ $('#notice').html( msg) refresh(3) } }; //prepare form $('#savetext').ajaxForm(options);

NAS ac ornare lectus MTCP nec.</div> Thanks.

  • Retain Delimiters when Splitting String

    - by JoeC
    Edit: OK, I can't read, thanks to Col. Shrapnel for the help. If anyone comes here looking for the same thing to be answered... print_r(preg_split('/([\!|\?|\.|\!\?])/', $string, null, PREG_SPLIT_DELIM_CAPTURE)); Is there any way to split a string on a set of delimiters, and retain the position and character(s) of the delimiter after the split? For example, using delimiters of ! ? . !? turning this: $string = 'Hello. A question? How strange! Maybe even surreal!? Who knows.'; into this array('Hello', '.', 'A question', '?', 'How strange', '!', 'Maybe even surreal', '!?', 'Who knows', '.'); Currently I'm trying to use print_r(preg_split('/([\!|\?|\.|\!\?])/', $string)); to capture the delimiters as a subpattern, but I'm not having much luck.

  • Clojure warn-on-reflection and type hints

    - by Ralph
    In the following code, I am getting a warning on reflection: (ns com.example (:import [org.apache.commons.cli CommandLine Option Options PosixParser])) (def *help-option* "help") (def *host-option* "db-host") (def *options* (doto (Options.) (.addOption "?" *help-option* false "Show this usage information") (.addOption "h" *host-option* true "Name of the database host"))) (let [^CommandLine command-line (.. (PosixParser.) (parse *options* (into-array String args))) db-host (.getOptionValue command-line "h")] ; WARNING HERE ON .getOptionValue ; Do stuff with db-host ) I have a type hint on command-line. Why the warning? I am using Clojure 1.2 on OS X 10.6.6 (Apple VM). I assume that I do not get a warning on (.addOption ...) because the compiler knows that (Options.) is a org.apache.commons.cli.Options).

  • How to perform an external request in Kohana 3?

    - by alex
    I've always used cURL for this sort of stuff, but this article got me thinking I could request another page easily using the Request object in Kohana 3. $url = 'http://www.example.com'; $update = Request::factory($url); $update->method = 'POST'; $update->post = array( 'key' => 'value' ); $update->execute(); echo $update->response; However I get the error Accessing static property Request::$method as non static From this I can assume it means that the method method is static, but that doesn't help me much. I also copied and pasted the example from that article and it threw the same error. Basically, I'm trying to POST to a new page on an external server, and do it the Kohana way. So, am I doing this correctly, or should I just use cURL (or file_get_contents() with context)?

  • Benefits of arrays

    - by Vitalii Fedorenko
    As I see it, the advantages of List over array are pretty obvious: Generics provide more precise typing: List<Integer>, List<? extends Number>, List<? super Integer>. List interface has a bunch useful methods: addAll, remove etc. While for arrays all standard operations except get/set must be performed in a procedure manner by passing it to a static method. Collections offer different implementations like ArrayList, LinkedList, unmodifieable and synchronized lists, which can be hidden under common List interface. OOB length control. As disadvantages I can only mention absence of syntactic sugar and runtime type check. At the same time supporting of both structures requires frequent using of asList and toArray methods, which makes code less readable. So I am curious if there are any important benefits of using arrays that I miss.

Here is the what I was thinking might work (I use ???? because i dont know what to catch): try{ images = new Array(frames); for (var i:uint = 0; i < frames; i++){ imagesBA[i] = new BitmapData(width, height, false, 0x000000FF); } } catch(error:????){ Alert.show("Out of memory!"); } Any idea what ???? can be? Or does anyone knows how to catch when there is no memory for a variable?

  • What is the best way to organize Java code since you can't pass by reference?

    - by Adam
    I'm learning how to code in Java after after coming from C. In C I always separated everything into individual functions to make the code easier to follow and edit. I was trying to do this in java but now since I realized that you can't use pointers, I am a bit confused as to what the best way to do this is. So for example I want to have a method that creates four alerts for me. So I pass it an alert builder that can then create the alerts. I can return them in an array, but in my code I already have the alerts individually named, and I would like to keep it that way so I wouldn't need to refer to them as alert[1], alert[2]... etc. So that means I would have to rename them, which would add additional code which would probably be longer than the code in the actual method! Am I thinking about this the right way? Is there anything I can do?

  • How to perform a join with CodeIgniter's Active Record class on a multicolumn key?

I need to join appearances on both the zone and installations tables. How can I do this?
