  • jquery plugin with multiple functions

    - by tcurdt
    According to the developer documentation jquery plugins are supposed to have only one namespace for all functions they make available. Which is straight forward as long as you only expose a single function per context (static/element). (function($){ var state_a = 0, $.myplugin = function(in_options) { // static return this; } $.fn.myplugin = function(in_options) { // element return this; } })(jQuery); This makes calls like this possible: $("elem").myplugin(options); jQuery.myplugin(options); What's the best approach if you have more than one function and need to share state? I would like to call into my plugin like this: $("elem").myplugin.start(options); $("elem").myplugin.stop(); jQuery.myplugin.start(options); jQuery.myplugin.stop();

  • Reading PowerPoint Effects with VBA

    - by OneNerd
    I have been working with VBA inside PowerPoint, and have a grasp on most things. What I am struggling with is reading the effect/animation settings for each object. I seem to be able to get a lot of what I need through the Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num) What confuses me is how to convert the numeric value of Powerpoint.ActivePresentation.Slides(slide_id).TimeLine.MainSequence(seq_num).EffectType to an effect (so looking for a table of values to effects or perhaps a CONST table). Also, how to read in all the different level of effects (like entrance, or emphasis, etc) is really confusing. not to mention I cannot wrap my head around the timeline (which seems like it is not really a timeline). Can anyone point me to any good articles or documentation that discusses how to read the effects and animations properly and fully? Thanks.

  • Selenium/NUnit run one test on multiple IP addresses.

    - by Matt Clarkson
    I have a test suite DLL written in C# that uses Selenium.This is then loaded into NUnit and tests can be performed on our embedded web server boards. Does anyone know how to run a NUnit Selenium test on multiple IPs in multiple browsers? I have tried creating multiple DefaultSelenium classes but they point to the same Internet Explorer window. I need multiple instances of the Selenium RC controlling individual Internet Explorer windows. Have been looking a lot on the Selenium User Group and in various documentation but can find a definitive answer. Cheers, Matt

  • Portable C++ library for IPC (processes and shared memory), Boost vs ACE vs Poco?

    - by user363778
    Hi, I need a portable C++ library for doing IPC. I used fork() and SysV shared memory until now but this limits me to Linux/Unix. I found out that there are 3 major C++ libraries that offer a portable solution (including Windows and Mac OS X). I really like Boost, and would like to use it but I need processes and it seems like that this is only an experimental branch until now!? I have never heard of ACE or POCO before and thus I am stuck I do not know which one to choose. I need fork(), sleep() (usleep() would be great) and shared memory of course. Performance and documentation are also important criteria. Thanks, for your Help!

  • Groovy 1.7 changes "final"?

    - by Aaron L. Carlow
    Just started learning Groovy, got the PragProg book "Programming Groovy" and had a problem compiling one of the sample scripts: class GCar2 { final miles = 0 def getMiles() { println "getMiles called" miles } def drive(dist) { if (dist > 0) { miles += dist } } } def car = new GCar2() println "Miles: $car.miles" println 'Driving' car.drive(10) println "Miles: $car.miles" try { print 'Can I see the miles? ' car.miles = 12 } catch (groovy.lang.ReadOnlyPropertyException ex) { println ex.message GroovyCar2.groovy: 20: cannnot access final field or property outside of constructor. @ line 20, column 35. def drive(dist) { if (dist > 0) miles += dist } ^ Groovy versions prior to 1.7 do not give an error. I looked through whatever documentation I could find and did not see the issue discussed. What is going on here? Aaron

  • Xcode 4.2 how include one project into another one?

    - by Alex Stone
    I keep searching, but cannot find a clear and simple explanation on how to include one XCode project, along with all of it's sub-classes into another project. I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself. Within XCode, along with .h and .m files, and folders, there's a whole new project, starting with a blue xcode project icon, that is expandable to contain everything within the project. Please, can someone explain to me step by step what do I need to do to add one XCode project into another one? I've seen a ton of one liners like "header search paths", but that does not tell me much. UPDATE: After re-reading the documentation, I realized that the project to include must be dragged ONTO the BLUE project icon of the parent project. Regular sources can be dragged anywhere, but a project must be dragged onto a project. Thank you!

  • Why Bluetooth needs DBUS way of communication in android?

    - by Rajesh SO
    I am newbie to Android DBUS, recently I was informed that I need to use DBUS to implement Bluetooth in Android, from DBUS documentation I see DBUS is used for communication medium between two applications. In Android apps -apps communication is through intents, if so why do we need DBUS for Bluetooth ? Is that DBUS serves as communication medium for networking (IP) between two apps since it is built over sockets? Please correct me if my understanding is wrong, any more information on DBUS along with Bluetooth implementation in Android is appreciated. Thanks.

  • How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

    - by brock
    Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

  • Sharepoint checkin/checkout

    - by Prashanth
    We have a sharepoint based application that uses a custom database for storing metadata/files (which could also be on a file share) My question is how can the standard file checkin/check out option in document library be customized? The javascript file ows.js in the layouts folder contains the functions that provide checkin/check out/ open file functionality. Behind the scenes it relies on a combination of HTTP Post/GET methods + SOAP + an activeX control to achieve the desired functionality. Customizing these javascript function seems tedious/error prone. Note that we have a web service that exposes endpoints, for retrieving necessary file information/data from the backend. The difficulty is in integrating it with the sharepoint js functions, due to lack of proper documentation. (Also the js functions might change over different versions of sharepoint) Also is it possible to create files/open files etc from the cache area on the client machine from server side code?

  • Regular expression to validate a Google Analytics UA Number

    - by Otis
    It's not 100 percent clear to me that the Google Analytics UA Numbers are always 6 digits, a dash, and 2 digits as Google often mentions in their documentation. There are frequent counter-examples that use fewer than 6 for the account portion and 1-4 for the profile. All of the examples always show numbers but it's not even clear that they can't be letters. Does anyone know if Google has published a regex that exactly matches allowable UA Numbers? I'm adding this feature to the admin console of an application I work on and would like to validate the user input.

  • Create user variable in Intellij File Template

    - by Matt Broekhuis
    I am trying to use Intellij's file templates (not live templates) to help mitigate how much boilerplate code I use when making Services, daos, and their interfaces. I am able to use all the system defined variables just fine, such as ${PACKAGE_NAME} What I want though, is to be able to use my own variable names, like ${MY_USER_INPUT} however, when i do this like above, I get an error The documentation says : It is also possible to specify arbitrary number of custom variables in format ${<VARIABLE_NAME>}. and then Intellij is supposed to prompt the user for the value. However, this just plain doesn't work for me. What am I missing?

  • Push data to flex client

    - by KensoDev
    Howday, I want to push data to flex clients. I am talking about anywhere between 5000-15000 concurrent users, need to get data every time a currency is changed so that means lots of changes for lots of users. I have been looking into WebOrb.net, but the performance seem very poor (100 users concurrent) for a product so pricy (we purchased a license). So, I have to look into alternatives, I know there's fluorineFx but it seems no one is really using it for products and it lacks in examples and documentation. My question is: what products can answer my needs (.net backend) and what are the performance I can expect out of these products? Thanks

  • How to share sessions between PHP and ASP.net application?

    - by citronas
    My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database. (e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application) How can we share the session between and PHP and an asp.net application? And does anyone have a hint for this 'coexisting' thing, that might be useful in development? Edit: IIS 6 would be our targeted server, altough IIS 7.5 would also be an option

  • python duration of a file object in an argument list

    - by msw
    In the pickle module documentation there is a snippet of example code: reader = pickle.load(open('save.p', 'rb')) which upon first read looked like it would allocate a system file descriptor, read its contents and then "leak" the open descriptor for there isn't any handle accessible to call close() upon. This got me wondering if there was any hidden magic that takes care of this case. Diving into the source, I found in Modules/_fileio.c that file descriptors are closed by the fileio_dealloc() destructor which led to the real question. What is the duration of the file object returned by the example code above? After that statement executes does the object indeed become unreferenced and therefore will the fd be subject to a real close(2) call at some future garbage collection sweep? If so, is the example line good practice, or should one not count on the fd being released thus risking kernel per-process descriptor table exhaustion?

  • Power Law distribution for a given exponent in C# using MathNet

    - by Eric Tobias
    Hello! I am currently working on a project where I need to generate multiple values (floats or doubles preferably) that follow a power law distribution with a given exponent! I was advised to use the MathNet.Iridium library to help me. The problem I have is that the documentation is not as explicit as it should be if there is any! I see multiple distributions that fit the general idea of the power law distribution but I cannot pinpoint a good distribution to use with a certain exponent as a parameter. Does anybody have more experience in that matter and could give me some hints or advice?

  • Start PyGTK cellrenderer edit from code

    - by mkotechno
    I have a treeview with an editable CellRendererText: self.renderer = gtk.CellRendererText() self.renderer.set_property('editable', True) But now I need to launch the edition from code instead from user, this is to focus the user attention in the fact he just created a new row and needs to be named. I tried this but does not work: self.renderer.start_editing( gtk.gdk.Event(gtk.gdk.NOTHING), self.treeview, str(index), gtk.gdk.Rectangle(), gtk.gdk.Rectangle(), 0) Neither does not throw errors, but the documentation about for what is each argument is not clear, in fact I really don't know if start_editing method is for this. All suggestions are welcome, thanks.

  • Ogg/Vorbis: _ov_fopen cannot be found

    - by knight666
    I'm trying to use Ogg/Vorbis with OpenAL to get sound in my game. Right now I'm simply trying to load a .ogg file and read its data, I'm not actually doing anything with it. I first tried using ov_open, however, the documentation said I should really be using ov_fopen on Windows. However, when I try to use that I get the following: 1>AudioManager.obj : error LNK2019: unresolved external symbol _ov_fopen referenced in function "private: static struct SomeGame::SoundData * __cdecl SomeGame::AudioManager::LoadOGG(char *)" (?LoadOGG@AudioManager@SomeGame@@CAPAUSoundData@2@PAD@Z) ...and when I Google "unresolved external symbol _ov_fopen", I get exactly one result. And it's in Japanese. So I tried downloading the ogg and vorbis source and compiling it, and inserting those in the project, but it still gives me the same error. Basically, how do I load in an Ogg/Vorbis file to be used with OpenAL on Windows? Thanks in advance.

    - by rithanyalaxmi
    Hi, I am a newbie to this forum,I was going through the documents of both Blackberry Widget and Java SDK. I have the following doubts to get clarified:- 1) Advantages and disadvantages of Java SDK and Widget SDK? 2) When to go for Java SDK and Widget SDK? 3) Both Java and Widget applications require the latest blackberry OS 5.0? OR whether they are compatible with the lower versions as well? 4) Whatever developed with Java SDK can be done with widget SDK? similarly the vice-versa? 5) Is it possible to create the .java classes for Widget application development? 6) Whether all the blackberry models supports both Java and Widget ? 7) What are the Databases the blackberry Java and Widget supports? Please do shed some light into this as i was unable to find a suitable documentation on these. Thanks, Rithu

  • Specification of Extended Properties in OleDb connection string?

    - by Monty
    At the moment I'm searching for properties for a connection string, which can be used to connect to an Excel file in readonly mode. Searching Google gets me a lot of examples of connection strings, but I can't seem to find a specification of all possibilities in the 'Extended Properties' section of the OleDb connection string. At the moment I've this: Provider = Microsoft.Jet.OLEDB.4.0; Data Source = D:\Data\Customers.xls; Extended Properties = 'Excel 8.0; Mode=Read; ReadOnly=true; HDR=Yes'; However... I've composed this by examples. So questions: 1. What is a decent source for OleDb Connection String documentation/reference? 2. Is the above connection string indeed connecting to the Excel file in readonly mode? Thanks!

  • Using Windows media foundation

    - by Martin Beckett
    Ok so my new gig is high performance video (think Google streetview but movies) - the hard work is all embedded capture and image processing but: I was looking at the new MS video offerings to display content = Windows Media Foundation. Is anyone actually using this ? There are no books on the topic. The only documentation is a developer team blog with a single entry 9 months old. I thought we had got past having to learn an MS api by spying on the com control messages! Is it just another wrapper around the same old activeX control?

  • How to protect web site against hackers?

    - by Adi barda
    Hi Guys, Like everyone of us, I have my own dreams about developing the next cool product that will be adopted by many users and become industry standard. Surprisingly, I find that the most challenging task is to keep my website up & running. My site is being hacked again and again no matter what I do - I blocked the FTP connections, changed the Joomla (CMS) database table names, installed all latest patches and what not. The web site supports the product (over 1800 users now...) by generating licenses, support forums, documentation, galleries etc. The product which is a winforms application cannot be marketed without this web site. My question: Do you have any innovative idea about securing joomla based web sites or what is the best secured web hosting you know. currently i'm hosting my site at ixwebhosting and i like them very much but obviously i can't do any serious marketing being hacked over and over again Thank you very much, Adi Barda

  • Do MyISAM holes get filled in automatically?

    - by NNN
    When you run a delete on a MyISAM table, it leaves a hole in the table until the table is optimized. This affects concurrent inserts. On the default setting, concurrent_inserts only work for tables without holes. However, in the documentation for MyISAM, under the concurrent_insert section it says: Enables concurrent inserts for all MyISAM tables, even those that have holes. For a table with a hole, new rows are inserted at the end of the table if it is in use by another thread. Otherwise, MySQL acquires a normal write lock and inserts the row into the hole. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_concurrent_insert Does that mean MyISAM automatically fills in holes whenever a new row is insert into the table? Previously I thought the holes would not be fixed until you OPTIMIZE a table.

  • Inherit from Type class of .Net

    - by Miguel Angelo
    Is there any point at all on inheriting from Type class in .Net? i.e. What could be the meaning of doing so? I am asking this because of this text in MSDN documentation: Notes to Inheritors When you inherit from Type, you must override the following members... list of members. MSDN doc for Type: http://msdn.microsoft.com/en-us/library/system.type.aspx ok, that is actually saying that anyone can inherit from Type... but they dont say why would you ever want to do that. Thanks!

  • Flexible argument list in LibreOffice Calc Macro

    - by Patru
    I want to write a function that geometrically links performance data which is usually provided as percentages, so the function will basically return (1+a)*(1+b)*(1+c)* … *(1+x)-1 This should be done using LibreOffice-calc and it should behave similarly to the regular sum function. As you may throw any number of arguments at sum I would like to be able to do the same with my alternative geoSum function but I am unable to find suitable documentation on handling a variable number of arguments with variable types (i.e. an arbitrary mix of numbers, cells and ranges). How would I have to specify the arguments to my LibreOffice-Basic function and how would I have to interpret it?
