• MooTools events not firing in IE8

  - by gregory

  I have a Mootools asset created like so: // Create a new asset var asset = new Asset.image(path, { title: this.language.download, events: {click: this.download.bind(this, link)}, }); I have a method of a MooTools object defined as such: download: function(e) { // The path to download console.log('download: ' + e); }, In Firefox the console.log print shows up. In IE8, however, I have no luck. Am I missing something? Any tips or advice would be greatly appreciated. TIA!

• C++/CLI .ToString() returning error

  - by George Johnston

  I am a beginner to C++/CLI as I come from a C# background. I am currently writing a wrapper for some native C++ code. I have the following methods: void AddToBlockList(System::String^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address); _packetFilter->AddToBlockList(cAddress); } void AddToBlockList(IPAddress^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address.ToString()); _packetFilter->AddToBlockList(cAddress); } ...The first method works fine and converts my string into the character array. However, the second function with the IPAddress object as the signiture gives me the following error: error C2228: left of '.ToString' must have class/struct/union ...When I type ? address.ToString() ...in the command window, the IP Address prints. Not sure where I'm going wrong. Any ideas?

• Confusing rails div id naming

  - by RailAddict

  I have started using jQuery and rails. I have made a simple form that submits to the database and updates the page without reloading with ajax. In my jQuery functions I used $"#new_comment" for the id name (in my application.js and create.js.erb files) but on my articles/show view file, I named the div "add_comment" and it works.. I renamed it new_comment and it breaks! Can someone explain it please? I get an error: "no action responded to 1" My function in my controller is "create".

• Returning a DOM element with Webdriver in Javascript

  - by ehmicky

  How do I return a DOM Element with Webdriver in Javascript? I am using the wd.js Javascript bindings: require("wd") .remote("promiseChain") .init() .get("http://www.google.com") .elementById("mngb") .then(function(element) { console.log(element); }); I am getting this weird object that is not a standard DOM Element (for example I cannot get the HTML code out of it): { value: '0', browser: { domain: null, _events: {}, _maxListeners: 10, configUrl: { protocol: 'http:', slashes: true, auth: null, host: '127.0.0.1:4444', port: '4444', hostname: '127.0.0.1', hash: null, search: '', query: {}, pathname: '/wd/hub', path: '/wd/hub', href: 'http://127.0.0.1:4444/wd/hub' }, sauceRestRoot: 'https://saucelabs.com/rest/v1', noAuthConfigUrl: { protocol: 'http:', slashes: true, host: '127.0.0.1:4444', port: '4444', hostname: '127.0.0.1', hash: null, search: null, query: null, pathname: '/wd/hub', path: '/wd/hub', href: 'http://127.0.0.1:4444/wd/hub' }, defaultCapabilities: { browserName: 'firefox', version: '', javascriptEnabled: true, platform: 'ANY' }, _httpConfig: { timeout: undefined, retries: 3, retryDelay: 15, baseUrl: undefined }, sampleElement: { value: 1, browser: [Circular] }, sessionID: '238c9837-3d82-4d90-9594-cefb4ba8e6b9' } }

• C# -Closure -Clarification

  - by nettguy

  I am learning C#.Can I mean closure as a construct that can adopt the changes in the environment in which it is defined. Example : List<Person> gurus = new List<Person>() { new Person{id=1,Name="Jon Skeet"}, new Person{id=2,Name="Marc Gravell"}, new Person{id=3,Name="Lasse"} }; void FindPersonByID(int id) { gurus.FindAll(delegate(Person x) { return x.id == id; }); } The variable id is declared in the scope of FindPersonByID() but t we still can access the local variable id inside the anonymous function (i.e) delegate(Person x) { return x.id == id; } (1) Is my understanding of closure is correct ? (2) What are the aditional advantages can we get from closures?

• How do I get developers to treat test code as "real" code?

  - by womp

  In the last two companies I've been at, there is an overriding mentality among developers that it's okay to write unit tests in a throw-away style. Code that they would never write in the actual product suddenly becomes OK in the unit tests. I'm talking Rampant copying and pasting between tests Code styling rules not followed Hard-coded magic strings across tests No object-oriented thought or design for integration tests, mocks or helper objects (250 line single-function tests!) .. and so on. I'm highly dissatisfied with the quality of the test code. Generally we do not do code reviews on our test assemblies, and we also do not enforce style or code analysis of them on our build server. Is that the only way to overcome this inertia about test quality? I'm looking for ideas to take to our developers, without having to go to higher management saying that we need to use resources for enforcement of test quality (although I will if I have to). Any thoughts or similar experiences?

• How to convert ByteString to [Word8] in Haskell?

  - by bodacydo

  I am dealing with ByteStrings and at this one place I need to use [Word8] but I have a ByteString. How do I convert a ByteString to [Word8] list? I tried unpack function from ByteString library but it returned a [Char] list rather than [Word8] list. Do I need to take this step and convert it first to [Char] list and only to [Word8] list? If so, how do I do that. Please advise the most efficient method! Thank you!

• Continuation monad "interface"

  - by sdcvvc

  The state monad "interface" class MonadState s m where get :: m s put :: s -> m () (+ return and bind) allows to construct any possible computation with State monad without using State constructor. For example, State $ \s -> (s+1, s-1) can be written as do s <- get put (s-1) return (s+1) Similarily, I never have to use Reader constructor, because I can create that computation using ask, return and (>>=). Precisely: Reader f == ask >>= return . f. Is it the same true for continuations - is it possible to write all instances of Cont r a using callCC (the only function in MonadCont), return and bind, and never type something like Cont (\c -> ...)?

• Ruby on rails link_to syntax

  - by mizipzor

  After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better. However, editing my \app\views\home\index.html.erb to contain: <h1>Rails test project</h1> <%= link_to "my blog", posts_path> I get an error: undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954> Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem. So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine. My question now is; how do I do that manually myself, define posts_path?

• Javascript: Do processing when user has stopped typing

  - by Midhat

  I have a text box on a web page, whose value I want to send to a XMLHttpRequest. Now I want the user to just type the value, without pressing a button. But If i just send the request int he keyboard events, it will fire every time a key is pressed. So basically I want something liek this function KeyUpEvent() { if (user is still typing) return; else do processing } It would be great if the solution could come from plain javascript or mootools. I dont want to use any other library.

• How to jQuery slidedown once page has already been loaded

  - by bulltorious

  I am having a timing issue when attempting to slide down my more info div. My desired functionality is that the div slidesdown from the top once the page has already been rendered. My problem is if I use $(document).ready().. the animation does not visibly occur. Here is my code: $(document).ready(function() { $(".MoreInfo").slideDown('slow'); }); If I strap it to some other element's click for example, it works beautifully. But I am not sure how to make it visibly slide down once the page has loaded. Thanks!

  i am using following code for animation using jquery. when i click on a list element, the corresponding div slides down and opacity goes to ‘1’.

• Stack calling convention between .NET & C on WinCE 6.0

  - by bernard

  Hi there. I'm porting a DLL written in C from WinCE 5.0 to WinCE 6.0 on an ARM target. This DLL is called by a .NET software. On WinCE5.0, everything runs fine. On WinCE6, I have the following problem: on InitInstance() of my DLL, I can call anything without problem (for example MessageBox()) or uses recursivity. Passed that point, the DLL is called by .NET code. And then it fails: even the arguments passed by .NET code seem weird. I can call MessageBox() once, but I can't call a function that calls MessageBox() and then that calls itself: recursivity is broken. It seems that the .NET code uses the stack in a different way than my C code. I'm very unfamillar with the Windows world and the company that gives me the .NET application does not understand yet why there is such a failure. Any pointer/hint/advice welcome! Thanks!

• how to match a regulas expresion like (%i1) in python pexpect

  - by mike

  I want to use maxima from python using pexpect, whenever maxima starts it will print a bunch of stuff of this form: $ maxima Maxima 5.27.0 http://maxima.sourceforge.net using Lisp SBCL 1.0.57-1.fc17 Distributed under the GNU Public License. See the file COPYING. Dedicated to the memory of William Schelter. The function bug_report() provides bug reporting information. (%i1) i would like to start up pexpect like so: import pexpect cmd = 'maxima' child = pexpect.spawn(cmd) child.expect (' match all that stuff up to and including (%i1)') child.sendline ('integrate(sin(x),x)') chil.expect( match (%o1 ) ) print child.before how do i match the starting banner up to the prompt (%i1)? and so on, also maxima increments the (%i1)'s by one as the session goes along, so the next expect would be: child.expect ('match (%i2)') child.sendline ('integrate(sin(x),x)') chil.expect( match (%o2 ) ) print child.before how do i match the (incrementing) integers?

• Javascript: Pass array as optional method args

  - by Dave Paroulek

  console.log takes a string and replaces tokens with values, for example: console.log("My name is %s, and I like %", 'Dave', 'Javascript') would print: My name is Dave, and I like Javascript I'd like to wrap this inside a method like so: function log(msg, values) { if(config.log == true){ console.log(msg, values); } } The 'values' arg might be a single value or several optional args. How can I accomplish this? If I call it like so: log("My name is %s, and I like %s", "Dave", "Javascript"); I get this (it doesn't recognize "Javascript" as a 3rd argument): My name is Dave, and I like %s If I call this: log("My name is %s, and I like %s", ["Dave", "Javascript"]); then it treats the second arg as an array (it doesn't expand to multiple args). What trick am I missing to get it to expand the optional args?

• Sharing output streams through a JNI interface

  - by Chris Conway

  I am writing a Java application that uses a C++ library through a JNI interface. The C++ library creates objects of type Foo, which are duly passed up through JNI to Java. Suppose the library has an output function void Foo::print(std::ostream &os) and I have a Java OutputStream out. How can I invoke Foo::print from Java so that the output appears on out? Is there any way to coerce the OutputStream to a std::ostream in the JNI layer? Can I capture the output in a buffer the JNI layer and then copy it into out?

• Is it possible to make a button on an AlertDialog that doesn't automatically close the dialog?

  - by Parker

  I have a simple list view with some check boxes in an alert dialog. I need to option to add a select all/none but you can't bring up the menu in an alert dialog, and I want to do this function from a button. From what I've seen any kind of button (positive, neutral, and negative) all close the dialog regardless. So, is this possible? If no, what alternatives do I have? My last mitigation is to simply create a new view and recreate everything. Is a new view the best solution?

• How can I unbind JQZOOM in my JQuery Script?

  - by Andy Barlow

  Hello, I have this script at the moment, which changes an image when a thumbnail has been changed. I then want JQZOOM to be added to that new image. However, if I put it inside the Onclick event, it gets slower and slower the more times you click on it... I guess because its running multiple instances. Is there anyway to unbind the JQZOOM from something then rebind it to something else? Here is my jquery at the moment: var options = { zoomWidth: 400, zoomHeight: 325, xOffset: 25, yOffset: 0, position: "right", lens: true, zoomType: "reverse", imageOpacity: 0.5, showEffect: "fadein", hideEffect: "fadeout", fadeinSpeed: "medium", title: false }; $('.jqzoom').jqzoom(options); $('.single-zoom-image').click ( function () { $('#bigProductImage').attr("src", $(this).attr("zoom")); $('.jqzoom').attr("href", $(this).attr("extrazoom")); }); Thanks in advance if anyone can help me. Cheers!

• getting window screenshot windows API

  - by Oliver

  Hi, I am trying to make a program to work on top of an existing GUI to annotate it and provide extra calculations and statistical information. I want to do this using image recognition, as I have learned a fair amount about this in University using Matlab and similar things. I can get a handle to the window I want to perform image recognition on, but I don't know how to turn that handle into an image of that window, and all its visible child windows. I suppose I am looking for something like the screenshot function, but restricted to a single window. How would I go about doing this? I suppose I'd need something like a .bmp to mess about with. Also, it would have to be efficient enough that I could call it several times a second without my PC grinding to a halt. Hopefully this isn't an obvious question, I typed some things into google but didn't get anything related.

• Drupal 5: CCK fields in custom content type

  - by Kuroki Kaze

  I have module that implements custom content type via NodeAPI hooks (hook_insert, hook_update etc). I want to add CCK field to this content type and populate it via hook_nodeapi calls like create or update (to show content nodes in Views). Problem is, I cannot access CCK fields for this content type. Sure, it's enabled on "Manage Fields" page, but when I load any node of this type with Devel module, I cannot see field attribute (field_flag) in node object. I can see it under "Dev Render" tab as part of "content" attribute, like $node-content['field_flag']['#value'], but if I assign value to $node-field_flag or $node-content['field_flag']['#value'] and call node_save, CCK fields are not saved. Maybe I must call some other function to save CCK fields? Or what may be wrong with this setup?

• Windows code pages, what are they?

  - by Mike D

  I'm trying to gain a basic understanding of what is meant by a Windows code page. I kind of get the feeling it's a translation between a given 8 bit value and some 'abstraction' for a given character graphic. I made the following experiment. I created a "" character literal with two versions of the letter u with an umlaut. One created using the ALT 129 (uses code page 437) value and one using the ALT 0252 (uses code page 1252) value. When I examined the literal both characters had the value 252. Is 252 the universal 8 bit abstraction for u with an umlaut? Is it the Unicode value? Aside from keyboard input are there any library routines or system calls that use code pages? For example is there a function to translate a string using a given code table (as above for the ALT 129 value)?
