  • Calling multiple functions simultaneously with jquery.

    - by clarke78
    I want to loop through an object that contains functions which will execute one after another. My most ideal approach would be to have these chain somehow (ie. func2 waits for func1 and func3 waits for func2) but this needs to happen dynamically and the functions will all have different durations. I'm using jQuery so I thought that perhaps "queue()" may help but I haven't worked with it much. A main concern is to not add any scope/callbacks to the functions within the object. I'd rather somehow enclose them within a parent function to execute within the loop in order to create the callback/chaining. Here's an example of what I've got now, but dumbed down. Thanks for any help! var obj = [ {'name':'func1','callback':function(){ alert(1); }}, {'name':'func2','callback':function(){ alert(2); }}, {'name':'func3','callback':function(){ alert(3); }} ]; $.each(obj, function(x, el) { el.callback(); });

  • jQuery & IE crashing on $('#someDiv').hide();

    - by Jimmy
    Well after a while of scratching my head and going "huh?" trying to figure out why IE would straight up crash when loading one of my pages loaded with jQuery goodness, I narrowed down the culprit to this line $('div#questions').hide(); And when I say IE crashes, I mean it fully crashes, attempting to do its webpage recovery nonsense that fails. I am running jQuery 1.4.2 and using IE 8 (haven't tested with any other versions) my current workaround is this: if ($.browser.msie) { window.location = "http://www.mozilla.com/en-US/products/download.html"; } For some reason I feel my IE users won't be very pleased with this solution though. The div in question has a lot of content in it and other divs that get hidden and displayed again, and all of that works just fine and dandy, it is only when the giant parent div is hidden that IE flips out and stabs itself. Has anyone encountered this or have any possible ideas of what is going wrong? EDIT: Everything is wrapped up in the $(document).ready(function() { }); And my code is all internal so I can't link it unfortunately.

  • when is a v-table created in C++?

    - by saminny
    When exactly does the compiler create a virtual function table? 1) when the class contains at least one virtual function. OR 2) when the immediate base class contains at least one virtual function. OR 3) when any parent class at any level of the hierarchy contains at least one virtual function. A related question to this: Is it possible to give up dynamic dispatch in a C++ hierarchy? e.g. consider the following example. #include <iostream> using namespace std; class A { public: virtual void f(); }; class B: public A { public: void f(); }; class C: public B { public: void f(); }; Which classes will contain a V-Table? Since B does not declare f() as virtual, does class C get dynamic polymorphism?

  • ListView getting deleted onbackpress

    - by adohertyd
    I have a listview in my mainactivity that makes a call to a database to populate it. When an item on the listview is clicked it starts a new activity showing the details of the item that was clicked. When the back button is pressed the listview is not displayed again. What could be the problem? This is the entirety of my mainactivity: public class MainActivity extends ListActivity { Button bAddMod; private ModuleDB db; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); db = new ModuleDB(this); db.open(); fillList(); db.close(); bAddMod = (Button) findViewById(R.id.btnAddMod); bAddMod.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent i = new Intent(MainActivity.this, AddModule.class); startActivity(i); } }); } private void fillList() { ListView lv = getListView(); Cursor curs = db.getData(); startManagingCursor(curs); MyCursorAdapter adapter = new MyCursorAdapter(getApplicationContext(), curs); lv.setAdapter(adapter); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id){ Intent k = new Intent(MainActivity.this, ModuleDetails.class); k.putExtra("mod_id", id); startActivity(k); } }); } }

  • Accessing Sub functions /procedures from DPR or other function / procedure in Delphi

    - by HX_unbanned
    Hello, stackoverflowers :) As much I know - Subroutines are with Private access mode to its parent unction / procedure, right? Is there any way to access them from "outer-world" - dpr or other function / procedure in unit? Also - which way takes more calcualtion and space to compiled file? for example: function blablabla(parameter : tparameter) : abcde; procedure xyz(par_ : tpar_); begin // ... end; begin // ... end; procedure albalbalb(param : tparam) : www; begin xyz(par_ : tpar); // is there any way to make this function public / published to access it therefore enabling to call it this way? end; // all text is random. // also, is there way to call it from DPR in this manner? // in C++ this can be done by specifing access mode and/or using "Friend" class .. but in DELPHI?

  • Is `super` local variable?

    - by Michael
    // A : Parent @implementation A -(id) init { // change self here then return it } @end A A *a = [[A alloc] init]; a. Just wondering, if self is a local variable or global? If it's local then what is the point of self = [super init] in init? I can successfully define some local variable and use like this, why would I need to assign it to self. -(id) init { id tmp = [super init]; if(tmp != nil) { //do stuff } return tmp; } b. If [super init] returns some other object instance and I have to overwrite self then I will not be able to access A's methods any more, since it will be completely new object? Am I right? c. super and self pointing to the same memory and the major difference between them is method lookup order. Am I right? sorry, don't have Mac to try, learning theory as for now...

  • Hibernate Relationship Mapping/Speed up batch inserts

    - by manyxcxi
    I have 5 MySQL InnoDB tables: Test,InputInvoice,InputLine,OutputInvoice,OutputLine and each is mapped and functioning in Hibernate. I have played with using StatelessSession/Session, and JDBC batch size. I have removed any generator classes to let MySQL handle the id generation- but it is still performing quite slow. Each of those tables is represented in a java class, and mapped in hibernate accordingly. Currently when it comes time to write the data out, I loop through the objects and do a session.save(Object) or session.insert(Object) if I'm using StatelessSession. I also do a flush and clear (when using Session) when my line count reaches the max jdbc batch size (50). Would it be faster if I had these in a 'parent' class that held the objects and did a session.save(master) instead of each one? If I had them in a master/container class, how would I map that in hibernate to reflect the relationship? The container class wouldn't actually be a table of it's own, but a relationship all based on two indexes run_id (int) and line (int). Another direction would be: How do I get Hibernate to do a multi-row insert?

  • Multi level menu, active links css highlight. (Ruby on Rails)

    - by klamath
    Site structure: / /products /products/design /products/photo /about I want to see parent menu item also highlighted by CSS, when child is active. (When 'design' or 'photo' is active 'products' should be highlighted too.) I'm using this for child and simple urls: <li class="<%= current_page?(:action => 'design') %>"> <%= link_to_unless_current 'Design', :design %> </li> For 'products' checking should be like: <%= current_page?(:action => 'products') || current_page?(:action => 'design') %> || current_page?(:action => 'photo') %> But triple || is not right, and it's become complicated. I saw a helper, like this one: def current(childs) if current_page?(:action => childs) @container = "active" else @container = "inactive" end end Which is used by: <%= current(:photo) %> So, how to put all my 3 checks for 'products', 'design', 'photo' in one helper? And make possible to use something like <%= current(:products, :design, :photo) %>

  • Simple Oracle File repository with folder hierarchy

    - by Ope
    I have an application that stores large amount of files (XML and binary) in folder hierarchies. Currently the main method is storing them in file system or using a legacy CMS, which we want to get rid of. The CMS supports Oracle and a customer wants to keep the files in Oracle because of enterprise policies (backup etc.) The question is: Is there a simple implementation of file repository with folder hierarchy for Oracle? What I am looking for is a small .Net component or example code (PL/SQL and/or .Net) that would have the following methods: Create, Delete, Exists Folder CRUD file Move and potentially Copy file or directory Access to files and folders with paths like "/root/folder1/folder2/file.xml" Ability to get all the files and folders in a folder and potentially also the entire directory tree Tree traversal, getting the parent, all children etc. needs to be fast. I need the implementation in .Net, but if it was just the stored procedures, I could create the .Net calling code. I have pointers to generic articles for creating hierarchies in DB, so if I need to do it from scratch, I know where to start. What I am asking here, is there already an implementation that I could take without doing this from scratch? It seems like such a generic requirement... If the answer is a CMS, Document management system or such it should be Open Source or at least quite cheap (some hundreds / server) and it should be possible to deploy it XCopy - hopefully only couple of DLL:s. I do not need - or want - a full featured big CMS with dozens of dlls and especially not an msi-installation. I have tried to google this, but the words "repository", "CMS", "file hierarchy" etc. give so many answers, the searches are pretty much useless. Thanks, OPe

  • Why aren't Java's generics implicitly polymorphic?

    - by froadie
    I'm a bit confused about how Java generics handle inheritance / polymorphism. Assume the following hierarchy - Animal (Parent) Dog - Cat (Children) So suppose I have a method doSomething(List<Animal> animals). By all the rules of inheritance and polymorphism, I would assume that a List<Dog> is a List<Animal> and a List<Cat> is a List<Animal> - and so either one could be passed to this method. Not so. If I want to achieve this behavior, I have to explicitly tell the method to accept a list of any subset of Animal by saying doSomething(List<? extends Animal> animals). I understand that this is Java's behavior. My question is why? Why is polymorphism generally implicit, but when it comes to generics it must be specified?

  • OOP + MVC advice on Member Controller

    - by dan727
    Hi, I am trying to follow good practices as much as possible while I'm learning using OOP in an MVC structure, so i'm turning to you guys for a bit of advice on something which is bothering me a little here. I am writing a site where I will have a number of different forms for members to fill in (mainly data about themselves), so i've decided to set up a Member controller where all of the forms relating to the member are represented as individual methods. This includes login/logout methods, as well as editing profile data etc. In addition to these methods, i also have a method to generate the member's control panel widget, which is a constant on every page on the site while the member is logged in. The only thing is, all of the other methods in this controller all have the same dependencies and form templates, so it would be great to generate all this in the constructor, but as the control_panel method does not have the same dependencies etc, I cannot use the constructor for this purpose, and instead I have to redeclare the dependencies and same template snippets in each method. This obviously isn't ideal and doesn't follow DRY principle, but I'm wondering what I should do with the control_panel method, as it is related to the member and that's why I put it in that controller in the first place. Am I just over-complicating things here and does it make sense to just move the control_panel method into a simple helper class? Here are the basic methods of the controller: class Member_Controller extends Website_Controller { public function __construct() { parent::__construct(); if (request::is_ajax()) { $this->auto_render = FALSE; // disable auto render } } public static function control_panel() { //load control panel view $panel = new View('user/control_panel'); return $panel; } public function login() { } public function register() { } public function profile() { } public function household() { } public function edit_profile() { } public function logout() { } }

  • Accessing "pseudo-globals" by their name as a string

    - by rob
    I am now in the process of removing most globals from my code by enclosing everything in a function, turning the globals into "pseudo globals," that are all accessible from anywhere inside that function block. (function(){ var g = 1; var func f1 = function () { alert (g); } var func f2= function () { f1(); } })(); (technically this is only for my "release version", where I append all my files together into a single file and surround them with the above....my dev version still has typically one global per js file) This all works great except for one thing...there is one important place where I need to access some of these "globals" by string name. Previously, I could have done this: var name = "g"; alert (window[name]); and it did the same as alert(g); Now -- from inside the block -- I would like to do the same, on my pseudo-globals. But I can't, since they are no longer members of any parent object ("window"), even though are in scope. Any way to access them by string? Thanks...

  • guarantee child records either in one table or another, but not both?

    - by user151841
    I have a table with two child tables. For each record in the parent table, I want one and only one record in one of the child tables -- not one in each, not none. How to I define that? Here's the backstory. Feel free to criticize this implementation, but please answer the question above, because this isn't the only time I've encountered it: I have a database that holds data pertaining to user surveys. It was originally designed with one authentication method for starting a survey. Since then, requirements have changed, and now there are two different ways someone could sign on to start a survey. Originally I captured the authentication token in a column in the survey table. Since requirements changed, there are three other bits of data that I want to capture in authentication. So for each record in the survey table, I'm either going to have one token, or a set of three. All four of these are of different types, so my thought was, instead of having four columns where either one is going to be null, or three are going to be null ( or even worse, a bad mashup of either of those scenarios ), I would have two child tables, one for holding the single authentication token, the other for holding the three. Problem is, I don't know offhand how to define that in DDL. I'm using MySQL, so maybe there's a feature that MySQL doesn't implement that lets me do this.

  • Problem with inherited classes in C#

    - by Unniloct
    I have a class called "Entity," with two child classes: "Creature" and "Item." (I'm making a game.) Creature has two functions called "Attack," one for attacking Creatures, and one for attacking Items. So far, everything works well. Now I'm working on the shooting bit, so I have a function called SelectTarget(). It takes all of the Entities (both Creatures and Items) in the player's view that the player can shoot and lets the player choose one. So here lies the problem: SelectTarget() returns an Entity, but I need some code to figure out whether that Entity is a Creature or an Item, and process it appropriately. Since this question looks kind of empty without any code, and I'm not 100% sure my explanation is good enough, here's where I'm at: if (Input.Check(Key.Fire)) { Entity target = Game.State.SelectTarget.Run(); this.Draw(); if (target != null) { //Player.Attack(target); // This won't work, because I have: // Player.Attack((Creature)Target) // Player.Attack((Item)Target) // but nothing for Entity, the parent class to Creature and Item. return true; } } (If the way the game is laid out seems weird, it's a roguelike.)

  • Another way to handle a common JQuery event handling pattern

    - by bradgonesurfing
    I have the following code for example $("a.foo").bind(function (e){ var t; if ( $(e.target).is("a") ){ t = $(e.target); }else{ t = $(e.target).parent("a"); } var data = t.attr("data-info"); }); In english. I might have a list of anchors within which there may be a number of spans. Each anchor is declared as <a class="foo" href="#" data-info="1"> <span> ... </span> <span> ... </span> </a> <a class="foo" href="#" data-info="2"> <span> ... </span> <span> ... </span> </a> ... ... I bind a handler to the click event of the anchor but the event object comes back with the anchor OR one of the spans depending on where I click. So to get my html5 "data-info" value into the callback I have to insert a bit of messy code. This is now appearing throughout my code to the point where I am guessing there might be an idiomatic JQuery way of handling this.

  • Objects leaking immediately from allocation using either new or [[Object alloc] init];

    - by Sam
    While running Instruments to find leaks in my code, after I've loaded a file and populate an NSMutableArray with new objects, leaks pop up! I am correctly releasing the objects. Sample code below: //NSMutableArray declared as a retained property in the parent class if(!mutableArray) mutableArray = [[NSMutableArray alloc] initWithCapacity:objectCount]; else [mutableArray removeAllObjects]; //Iterates through the read in data and populate the NSMutableArray for(int i = 0; i < objectCount; i++){ //Initializes a new object with data MyObject *object = [MyObject new]; //Adds the object to the mutableArray [mutableArray addObject:object]; //Releases the object [object release]; } I get a number of leaks from Instruments terminating at the addition of the 'object' into the 'mutableArray', but also including the allocation of the 'object' and the 'mutableArray'. I don't get it. Not to mention, this is happening on the first call of the enclosing method so the allocation of the NSMutableArray is being hit in the logic block, not the 'removeAllObjects' selector. Lastly, does Core Foundation have a major bug in it that randomly creates CFStrings and mismanages their memory?
