  • Where does code within Script tags go in the resulting AS class?

    - by Hanno Fietz
    I was wondering what happens to the code contained in an <mx:Script> tag. If I define a function tehre, it just becomes a member function of the generated class. But I noticed that it seems OK for the compiler if I just write some (static) method calls there (specifically, I call Font.registerFont()). I feel kind of guilty for doing this, because I have no idea what's really happening and when the code gets executed.

  • Hibernate (JPA) Entity with Static collection as a member

    - by Kyle Partridge
    Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database? I know I could just query this, but I was wondering if there was a more elegant solution, as it seems like something that other people may have come across.

  • How do you get the width of an element without a defined width?

    - by Moak
    How would you find out the width of a element that is wrapped by 20 odd other elements, but the only fixed width I know is the main wrapper's which is 800px. All child elements are generally blocks, floating or not, with different paddings and margins. I don't really need the answer to a specific case, I'm just wondering if there are tools or tricks to quickly calculate such things. Thanks

  • How Would you Mimic an Arbitrary Directory Structure with Rails Routes?

    - by viatropos
    I want to be able to map Google Docs' folder system to urls in my application and am just wondering how I can say "route, I want you to match an arbitrary set of nodes, and the last one is the file (or possibly a directory, I can check in the controller)". So I could do things like: www.mysite.com/documents/folder1/childfolderA/document www.mysite.com/documents/root-level-doc Can the routes.rb file do something like this?

  • Listing C Constants/Macros

    - by ZJR
    Is there a way to make the GNU C Preprocessor, cpp (or some other tool) list all available macros and their values at a given point in a C file? I'm looking for system-specific macros while porting a program that's already unix savvy and loading a sparse bunch of unix system files. Just wondering if there's an easier way than going hunting for definitions.

  • Port Android App to Desktop?

    - by CodeJustin.com
    I'm just wondering if it would be possible (and legal) to port an Android app to desktop? I'm creating an android game that would work well on PC too (even with the cellphone like layout) and was thinking that maybe I could 'embed' an android emulator with an installer or would that process be a bit hard for a novice Java coder?

    - by chobo2
    Hi I am planning to try to use XML Serialization in C# but I am wondering if I get a .xml file how do I check if the xml file confirms to the right type?

  • Handling large numbers of sockets with .NET

    - by Dreaddan
    I'm looking at writing a application that need to be able to handle in the region of 200 connections / sec and was wondering if C# and .NET will handle this or if I need to really be looking at C++ to do this? It looks like SocketAsyncEventArgs may be the way to go but thought id check before I plough in to it. Each transaction should only last less than a second but could take up to 15 seconds each if that makes any difference.

    - by KiiroSora09
    I'm asked to create an online booking system with online payment and I'm wondering what to do in the case when 2 customers booked for the same room(s) at the same time. For Example: At the same time: Customer1 and Customer2 booked for a standard room which only has 1 room available. (The Room availability will display that there is still 1 room available). And then they hit the 'confirm' button at the same time.

  • Eclipse - limiting a command's visibility to a specific perspective

    - by Tom
    How do I limit the visibility of an Eclipse command in menus and the toolbar to just one perspective? It is currently showing up in all perspectives, but it only makes sense to have it around when working in this particular perspective. It seems like this could be done with "contexts", but I was wondering if there was something simpler.

    I'm working with Twitter Bootstrap and the regular navbar you see in the guides: http://twitter.github.io/bootstrap/components.html#navbar I don't want the navigation to stretch all the way left or right but stay where I can see both sides just like in the guide. The only difference is it would be fixed to the top. I was wondering, how do I make this become a fixed navbar as if I was using the navbar-fixed-top class?
