  • What's a good jQuery ligthbox plugin that cycles through images? (like a carousel)

    - by Greg
    I'm looking for a jQuery lightbox plugin that has the ability to, with it's next and previous buttons, cycle through images repeatedly. Like a carousel effect. I've been using jQuery Lightbox Plugin (balupton edition) but that doesn't have the option to continue cycling through images. It reaches the last image in the array and then disables the 'next' button. So to save me some time coding, what are some plugins you can recommend?

There are many ways to do that but I can't determine the best/easiest way to just convert the text (string) into array of bits. Any clue ? In C#

    - by KMC
    I have an array of button which is dynamically generated at run time. I have the function for button click in my code, but I can't find a way to set the button's click name in code. So, what is the code equivalent for XAML: <Button x:Name="btn1" Click="btn1_Click"> Or, what should I place for "????" in the following Code: Button btn = new Button()btn.Name = "btn1";btn.???? = "btn1_Click";

  • iPhone SDK: Track users location using GPS

    - by Nic Hubbard
    I have a few questions about CoreLocation and GPS. First, what method in core location is used to continually get the users current coordinates? And at what interval should these be retrieved? Second, should these coordinates be pushed into a NSMutableArray each time they are received, so that the array of coordinates will represent the users path? Thanks, just wanting to get started getting me mind around this.

  • How to calculate "holes" in timetable

    - by genesiss
    I've got a 2-dimensional array like this (it represents a timetable): http://www.shrani.si/f/28/L6/37YvFye/timetable.png Orange cells are lectures and whites are free time. How could I calculate number of free hours between lectures in the same day? (columns are days and rows are hours) For example, in this table the result should be: 2 for first column 0 for second colum -- The function returns 2 (because 2+0=2)

  • Atmospheric scattering OpenGL 3.3

    Im currently trying to convert a shader by Sean O'Neil to version 330 so i can try it out in a application im writing. Im having some issues with deprecated functions, so i replaced them, but im almost completely new to glsl, so i probably did a mistake somewhere.

  • Is it bad to use a model directly from a view in codeigniter?

    - by jason
    I know normally the data is passed thru to the view with the controller. however, currently in my view I load my model ($this-load-model('Db_model');) so i can use it in a loop to retrieve a users profile picture path from a array of IDs that is passed from controller. Will loading the db model in the view to accomplish this make my site more vulnerable or bad form? To me it seems to be outside of MVC concept but its working atm. thanks

  • Magento and configurable product attributes

    - by artega
    I have an issue with displaying product custom attributes. I've read every resources through google but still no success. The problem is that I have to show size attribute of configurable product on category grid and list view. Every solution on google suggested something like $_product->getAttributeText('size') but I ended up at just a single string - "S" or "M" instead of an array. How can I fetch all possible sizes of all simple products which belongs to particular configurable product without much hassle?

But I need to use "split" method and save store the outputs in a array. so I can't use the Match Method. So please help me...
