  • Attach fancybox/lightbox/idontknowbox function on an element

    - by tanathos
    I'm developing a jquery gallery, and I want to parametrize the highlighter function to support any kind of lightboxes (fancybox for example). In my defaults I did something like: $.fn.mygallery.defaults = { functionHighlighter: null } so in the code, creating the item, I'll check this property, and if it's setted to a function, I want to call it on the element: if ((typeof opt.functionHighlighter) === "function") { opt.functionHighlighter.call(link); } where link is the anchor element containing the miniature image, with href setted to the original image. In my idea, when the plugin is called, I set the function with: $("#gallery").mygallery({ functionHighlighter: $.fancybox }); but the "call" on the functionHighlighter executes directly the fancybox, that returns an empty area. What I want to emulate is the execution of link.fancybox(); that correctly builds the plugin on link. Any ideas?

  • Techniques for Visualizing Data

    - by Rob Wilkerson
    I'm looking into providing several methods of visualizing a large volume of data. This may include, but will not be limited to, simple graphing. The techniques I'm exploring will involve shapes, text and lines. It will also involve interaction with elements (hiding, focusing, etc.) and animation (shifting, dragging, systematic reorganizing, etc.) of those elements. SVG or Canvas seem like the obvious choices (in conjunction with a JS library--probably jQuery), but the lack of cross-browser availability is a concern. I'd prefer to avoid Flash/Flex, but right now it's the only rock solid, cross-browser technology I've found if support for IE7/8 is a requirement. Does anyone have any other suggestions or any additional information that would make a technology I've listed seem even more appealing? Thanks.

  • Can managed and unmanaged C++/MFC be mixed in one dll?

    - by Walter Williams
    Previously we had software in MFC (VC6), VB6 and C# applications that needed to call the same engine written in C++ (and MFC). The engine required C++ for speed. At the time we decided to use COM as the interface because all three could use it with the least issues in marshalling, etc. Our MFC application is now deprecated and we have recently decided to dump VB6, so what we've got left is C#. We can just leave the COM engine as-is, but it would be nice to get away from COM registration, etc., and have a managed interface to work with. COM registration occasionally causes support issues if there is something wrong with the person's machine. Is it possible to have a dll with the existing unmanaged C++/MFC, and a .NET front end interface?

  • Registry corrupted for testing?

    - by Emile
    Hi. Forgive my ignorance. I'm a lowly LAMP stack developer and this is my first post for "c++". We had an Internet Explorer add-on commissioned but then lost support. Allegedly each version has to be have been tested "on a fresh computer since old add-ons could have cause registry errors." I'm not familiar with IE add-on development (or c++ dev). Is this common? Can't one simply reverse registry errors? How to continue testing iterations on one machine? Thanks!

  • Will a CF code run on regular server?

    - by Joann
    I am tasked to integrate a CF code(about 70 lines) into our site then configure it to communicate to another site's server. However, our hosting site is just a typical server without CF support. Will the code run? All I know is that CF is Adobe's version of PHP and ASP. I have no experience coding it. Could you please enlighten me? From what I gathered from the internet, you have to have a CF server in order to run a CF code but the resources seem scarce. I just need someone knowledgeable to verify...

  • Making ofHideReadOnly work with UseLatestCommonDialogs

    - by Jan Goyvaerts
    In Delphi 2007 and later, the global variable UseLatestCommonDialogs causes TOpenDialog to use the new Vista-style dialog on Windows Vista and 7. That's cool. Unfortunately, the Vista-style dialog does not seem to support the ofHideReadOnly option of TOpenDialog. The read-only checkbox never appears regardless whether this option is set to True or False. How can I make TOpenDialog show a read-only checkbox on the Vista-style dialog? TOpenTextFileDialog adds a combo box to the dialog regardless of whether it's Vista-style or not. It should be possible to add a read-only checkbox in the same way, but I can't figure out how to do it, even when looking at the source for TOpenTextFileDialog.

  • Choosing between YUI Charts or Google Visualization API

    - by r2b2
    Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

  • How can I build against Microsoft.Web.Administration (IIS 7.x) on a Windows 2003 build machine?

    - by JohnL
    Hi, I am writing a C# config app for (amongst other things) setting up websites. It's only required to support IIS 7.x (Windows 2008 / 2008 R2), and requiring the compatibility pack is a no-no, so I figured I'd just use the Microsoft.Web.Administration namespace. However, the only place I can find the assembly that contains this namespace (Microsoft.Web.Administration.dll) is from the IIS 7.x installation folder, and our main build machines are Windows 2003 and so cannot install IIS 7.x. One option is to mandate a 2008 build machine but we currently only have one so that's not ideal. We've already ruled out appcmd.exe. The other option is to make a package consisting of the dlls necessary to build against Microsoft.Web.Administration.dll. Has anyone tried that? Is there such a package already in existence, hidden somewhere on the MS download site? Thanks in advance.

  • Is Eclipse Remote System Explorer broken on Windows?

    - by Kev
    I have the following setup on Windows 7 Ultimate x64: Eclipse Indigo 2.7.2 (Build: M20120208-0800) Remote System Explorer 3.3.2 (see screenshot) (Oracle/Sun) Java 1.6 Update 31 (x86) Despite all my best efforts I am unable to connect to a remote system (a Centos 5.6 server on my local LAN) using a Remote System Explorer SSH connection - I've tried both password authentication and using my SSH private key. Here is a screenshot of both the Eclipse error dialogue and what is logged in my /var/log/secure log file: /var/log/secure: Apr 1 12:00:21 nagios sshd[6176]: Received disconnect from 172.16.3.88: 3: com.jcraft.jsch.JSchException: Auth fail When I connect for the first time I do get prompted to verify the authenticity of the remote host and the RSA key fingerprint. But that's as far as things go. Performing the same operation with the same credentials on my Fedora Core 16 box (also running the same version of Eclipse and Java) to the same server is successful. This leads me to believe that RSE SSH support on Windows is either broken or there's some piece of the SSH-on-Windows puzzle I'm missing. Is this the case?

  • FTP client to zip before upload and unzip on the server after upload

    - by Ronaldo Junior
    I am always working with some big websites that is annoying to upload given the number of small files. I use Filezilla but am happy to buy some commercial solution if there is one out there that can zip the files before upload and then unzip it after upload. Its a pain to have to manually do that all the time. If someone know of any ftp client or extension for Filezilla or other that would do that... I sent an email to the support for CuteFTP and WSFtp - no answer so far... I know FTP protocol does not allow this command - thats why Im asking for a extension (if anyone know) or a free or commercial FTP client that do the job...

  • Hudson, C++ and UnitTest++

    - by Gilad Naor
    Has anyone used Hudson as a Continuous-Integration server for a C++ project using UnitTest++ as a testing library? How exactly did you set it up? I know there have been several questions on Continuous Integration before, but I hope this one has a narrower scope. EDIT: I'll clarify a bit on what I'm looking for. I already have the build set to fail when the Unit-Tests fail. I'm looking for something like Hudson's JUnit support. UnitTest++ can create XML reports (See here). So, perhaps if someone knows how to translate these reports to be JUnit compatible, Hudson will know how to eat it up?

  • Twitter xAuth vs open source

    - by Yorirou
    Hi I am developing an open source desktop twitter client. I would like to take advantage on the new xAuth authentication method, however my app is open source which means that if I put the keys directly into the source file, it may be a vulnerability (am I correct? The twitter support guy told me). On the other hand, putting the key directly into a binary also doesn't make sense. I am writing my application in python, so if I just supply the pyc files, it is one more seconds to get the keys, thanks to the excellent reflection capatibilities of Python. If I create a small .so file with the keys, it is also trivial to obtain the key by looking at the raw binary (keys has fixed length and character set). What is your opinion? Is it really a secutiry hole to expose the API keys?

  • Preprocessor macros: how to insert arguments?

    - by mhambra
    Hi all, the code has a number of following sections: int filter; #ifdef INPUTFILTER_FOO LOG4CXX_DEBUG(log, "FOO filter used"); filter = F_FOO; #endif They are used multiple times in the code (used to provide I/O, threading support etc for all testing configurations), Circa they are essential for debugging but make the code look harsh, want to replace them with macros, one for each category_type namespace. So, want to expand the following: MACROSTUFFBAZ(log2, stuff, "BAZ") <- the text part is unique for each class, so it needs to be included in macro too. to: #ifdef INPUTSTUFF_BAZ LOG4CXX_DEBUG(log2, "BAZ stuff used"); stuff = S_BAZ; #endif To define macros, plan to use this: debug.hpp: #ifdef INPUTSTUFF_BAZ #define MACROSTUFFBAZ ... #else #define MACROSTUFFBAZ .. no code! #endif #endif (at least this will give a clear overview of the things currently undergoing probation, without seeing them around the code)

  • Do Ruby/Rails state machines exist that execute event transitions when a state change occurs?

    - by Bryan
    Hello All, Hopefully this isn't a silly question and I'm just not overlooking something in Ruby/Rails state machines (AASM, Transitions, AlterEgo, etc). From what I can tell, these state machine implementations operate on the preface that an event will get fired and the appropriate transition for that event will be triggered based on the old and new state. However, they don't seem to work the other way; say a user wants to change state from 'created' to 'assigned' and have the correct transition occur (rather than firing the event that causes the current state to be transitioned to the new state). Essentially, I want the user to be able to select a new state from a select box of available states and have the appropriate transition, guards, success callbacks, etc executed. Does anyone know if the existing state machine implementations support this?

  • MySQL primary/foreign key size?

    - by David
    I seem to see a lot of people arbitrarily assigning large sizes to primary/foreign key fields in their MySQL schemas, such as INT(11) and even BIGINT(20) as WordPress uses. Now correct me if I'm wrong, but even an INT(4) would support (unsigned) values up to over 4 billion. Change it to INT(5) and you allow for values up to a quadrillion, which is more than you would ever need, unless possibly you're storing geodata at NASA/Google, which I'm sure most of us aren't. Is there a reason people use such large sizes for their primary keys? Seems like a waste to me...

  • Making an SVG DOM JavaScript class

    - by CryptoQuick
    I'm unsatisfied with other JavaScript libraries and frameworks like jQuery, MooTools, and Raphael, because of their inability to support SVG grouping. You'd think it'd be a very simple thing for them to implement. Anyway, I'm trying to make a JavaScript class (using John Resig's class.js script) like this: var El = Class.extend({ el: null, svgNS: "http://www.w3.org/2000/svg", init: function (type) { this.el = document.createElementNS(this.svgNS, type); }, set: function (name, attr) { this.el.setAttributeNS(null, name, attr); }, get: function (el, name) { var attr = this.el.getAttributeNS(null, name); return attr; }, add: function (targEl) { targEl.el.appendChild(this.el); }, remove: function (targEl) { targEl.el.removeChild(this.el); }, setEl: function (docId) { this.el = document.getElementById(docId); } }); I can add elements to the DOM using these statements outside of the class, but storing the element inside the class becomes problematic. Anyone have any creative ideas?

  • Jar extraction and verification in BlackBerry

    - by Basilio
    Hi All, The application I am currently working on requires me to extract contents from and verify the authenticity of the signed jar that is stored on the SD Card. In Java [and Android], we have the java.util.jar and java.util.zip classes, that allow to extract jar. However, J2ME or BlackBerry® does not provide support for these packages. I have, however, successfully extracted these using the third party ZipMe library. Can anyone let me know, how to get the signature block from the .DSA/.RSA file to authenticate the jar? I have the certificate that was used to sign the jar as well. This is easily done in Java using the getCertificates() method available in java.util.jar.JarFile. Is there any 3rd party API available that emulates the JarFile for BlackBerry®? Any help in this regard will be deeply appreciated. Thanks & Regards Basilio John Vincent D'souza

  • Tornado Web & Persistent Connections

    - by Engrost
    How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like that: class MainHandler(RequestHandler): count = 0 @asynchronous def post(self): #get header content type content_type = self.request.headers.get('Content-Type') if not content_type in ACCEPTED_CONTENT: raise HTTPError(403, 'Incorrect content type') text = self.request.body self.count += 1 command = CommandObject(text, self.count, callback = self.async_callback(self.on_response)) command.execute() def on_response(self, response): if response.error: raise HTTPError(500) body = response.body self.write(body) self.flush() execute calls callback when finishes. is my asumption right that with things that way post will be called many times and for one connection count will increase with each httprequest from client? but for each connection I will have separate count value?

  • What would you recommend for a large-scale Java data grid technology: Terracotta, GigaSpaces, Cohere

    - by cliff.meyers
    I've been reading up on so-called "data grid" solutions for the Java platform including Terracotta, GigaSpaces and Coherence. I was wondering if anyone has real-world experience working any of these tools and could share their experience. I'm also really curious to know what scale of deployment people have worked with: are we talking 2-4 node clusters or have you worked with anything significantly larger than that? I'm attracted to Terracotta because of its "drop in" support for Hibernate and Spring, both of which we use heavily. I also like the idea of how it decorates bytecode based on configuration and doesn't require you to program against a "grid API." I'm not aware of any advantages to tools which use the approach of an explicit API but would love to hear about them if they do in fact exist. :) I've also spent time reading about memcached but am more interested in hearing feedback on these three specific solutions. I would be curious to hear how they measure up against memcached in the event someone has used both.

  • Windows Azure Table Storage LINQ Operators

    - by Ryan Elkins
    Currently Table Storage supports From, Where, Take, and First. Are there plans to support any of the other 29 operators? If we have to code for these ourselves, how much of a performance difference are we looking at to something similar via SQL and SQL Server? Do you see it being somewhat comparable or will it be far far slower if I need to do a Count or Sum or Group By over a gigantic dataset? I like the Azure platform and the idea of cloud based storage. I like Windows Azure for the amount of data it can store and the schema-less nature of table storage. SQL Azure just won't work due to the high cost to storage space.

  • Architectural decision : QT or Eclipse Platform ?

    - by umanga
    We are in the process of designing a tool to be used with HDEM(High Definition Electron Microscope).We get stacks of 2D images from HDEM and first step is 'detecting borders' on the sections.After detecting edges of 2D slices ,next step is construct the 3D model using these 2D slices. This 'border detecting' algorithm(s) is/are implemented by one of professor and he has used and suggests to use C.(to gain high performance and probably will parallelise in future) We have to develop comprehensive UI ,3D viewer ,2D editor...etc and use this algorithm. Application should support usual features like project save/open.Undo,Redo...etc Our technology decisions are: A) Build entire platform from the scratch using QT. B) Use Eclipse Platform Our concerns are, if we choose A) we can easily integrate the 'border detecting' algorithm(s) because the development environment is C/C++ But we have to implement the basic features from the scratch. If we choose B) we get basic features from the Eclipse platform , but integrating C libraries going to be a tedious task. Any suggestions on this?

  • CPU temperature monitoring C#

    - by Paul
    For a programming project I would like to access the temperature readings from my CPU and GPUs. I will be using C#. From various forums I get the impression that there is specific information and developer resources you need in order to access that information for various boards. I have a MSI NF750-G55 board. MSI's website does not have any of the information I am looking for. I tried their tech support and the rep I spoke with stated they do not have any such information. There must be a way to obtain that info. Any thoughts?

  • Custom Date Format with jax-rs in apache cxf?

    - by Oscar Chan
    Hi, I have been googling to figure out how I can customize the Date format when I use jax-rs on apache CXF. I looked at the codes, and it seems that it only support primitives, enum and a special hack that assume the type associated with @ForumParam has a constructor with a single string parameter. This force me to use String instead of Date if I want to use ForumParam. it is kind of ugly. Is there a better way to do it? @POST @Path("/xxx") public String addPackage(@FormParam("startDate") Date startDate) { ... } Thanks
