• How to create picture slideshows in a rails project? Flash or otherwise

  - by Janak

  In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else. I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images I imagine there must be a plugin or something to handle this?

• Alfresco 3 Labs: Adding a thumbnail to a document

  - by Ace

  Hey guys! Any Alfresco experts out there? I have created a document type in Alfresco and am trying to associate it with an image -- Somehow. I don't really mind how it's done - an image uploader in the metadata section when saving the actual document would be nice, but I can live with having to upload the image first and then associating it somehow with the document. Any ideas..?

• RoR - Associations into practise - forms (View)

  - by NicoJuicy

  I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

• easy hex/float conversion

  - by yeus

  I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link: http://docs.python.org/library/stdtypes.html#additional-methods-on-float Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes... thx for the answers!

• Suggestions for jQuery-based Date/Time Selector

  - by Jason Palmer

  Hi everyone, I'm in search for a jQuery-based Date/Time Selector. I have found a few that are quite nice, but one of my requirements is that I can provide a json/xml/etc source of available days/times and the control should only allow selections of available days/times. Is anyone aware of a plugin that does this, or at least a plugin that could be modified to do this? Thanks!

• quick to setup version control that integrates well with VS2010

  - by raklos

  I've got to a point where i want to start using version control for my project. Mainly for reverting to previous versions of files if things go belly up, doing diff comparisons. Nothing major.

Im just using my pc for this so something like TFS is out of the question.

  - by CMW

The web address of some web sites end with ".aspx", ".php", ".jsp", etc. But some web address do not contains any indicators. Is there any systematic way we can use to know the technologies used by a web site? Thanks.

• Is there an open source MVP framework for C++?

  - by morpheous

  I am looking for a lightweight set of C++ classes that implement/show how to use the MVP design pattern, so that I can refactor some legacy code I am working on. A library/framework would be nice to get me started. A quick google search seems to bring up only C# examples - is anyone aware of any C++ ones out there? [Edit] I am particularly interested in a Passive viewer, as I want to completely decouple the view from the model.

• J2EE: Create a form for uploading an unknown number of files

  - by sabauma

  I need to create a form that will allow, among other things, a user to upload an unknown number of files to the server running Tomcat using J2EE. It would be nice if the form could add upload slots to the form as needed. I haven't found much useful on the subject, so I thought I would poll the community. -Spenser

• PHP's form bracket trick is to Django's ___?

  - by Matt

  In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

  - by Hamish Grubijan

  Hi, I have heard that MbUnit comes with pretty nice test decorators which allow writing db-related tests with ease. I am struggling to find good documentation with samples. Also, can the same thing be achieved with the latest Micosoft's Test package? Many thanks.

• How to checking wether an object has a specific method or not

  - by Ghommey

  Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell wether $myObject has a method called helloWorld or not?

• How to determine at runtime hen your C++ application has the visual studio debugger attached?

  - by Jeremy Bell

  How do you determine at runtime whether the visual studio debugger is attached to your process. I've seen instructions for how to do this in .NET, but my process is a native C++ process. Support for detecting Just-in-time debugging would be nice but not a strict requirement.

• What is the fastest XML parser in PHP?

  - by Jakub Lédl

  Hi, for a certain project, I need some way to parse XML and get data from it. So I wonder, which one of built-in parsers is the fastest? Also, it would be nice of the parser could accept a XML string as input - I have my own implementation of thread-safe working with files and I don't want some nasty non-thread-safe libraries to make my efforts useless.

• Good Way to Debug Visual Studio Designer Errors

  - by Daisuke Shimamoto

  Hi, Does anyone know a good way to debug errors in the Visual Studio Designer? In our project we have tons of UserControls and many complex forms.

The language is C# and we're using Visual Studio 2005. Thanks, Daisuke

• ActiveSync File Explorer alternative

  - by Andy White

  Is there an alternative to the ActiveSync "Explore" for looking at the file system of a Windows Mobile device? (This same thing can also be accessed from My Computer - Mobile Device). It would be nice if you could just navigate into the device and view or edit files without having to copy them back and forth from the PC. Why does it work this way in the first place? Is the Explore view sort of a "virtual" version of your phone's file system that cannot be edited directly?

  In the app I'm building, I'd like to have a nice footer with data from the database (tags) and a contact-form. All the parts are scripted, but now I'd like to put them all together. The elements of the footer are the same for every page loaded, only the content is different. How can I do this, without having to put too much code on every controller?

• Disable browser zoom on certain elements in Firefox

  - by Jonathan Morgan

  Is it possible to disable the in-browser, full-page zoom in Firefox (activated by Ctrl +) for a webpage? How about for certain elements in a webpage? I just notice that sometimes elements look really weird when they are zoomed, and it might be nice to just disable the zooming completely for those elements. Note: I know there a few ways to find the zoom level, but this is really wanting to actively work around it (which might not be a good idea anyway).
