• AS3: How to dispatch from the document class?

  - by redconservatory

  I have a pretty good handle on dispatching from classes other than the Document Class, but what happens when I want to dispatch an event from the Document class and have other classes listen to the document class broadcast? It seems like there are several ways to approach this (i.e using a Singleton, using composition, using MovieClip(root)) I was just wondering what people find is the "best practice" way to do this?

• Looking for a specific python gui module to perform the following task

  - by Sadaf Amouz

  I am looking for a GUI python module that is best suited for the following job: I am trying to plot a graph with many columns (perhaps hundreds), each column representing an individual. The user should be able to drag the columns around and drop them onto different columns to switch the two. Also, there are going to be additional dots drawn on the columns and by hovering over those dots, the user should see the values corresponding to those dots. What is the best way to approach this?

• Confused about distinct/aggregate queries with (N)Hibernate

  - by nw

  I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?

• Using Predicate of a class to Search Generic list - Faster than looping?

  - by Srikanth

  Lets say we have a generic list of Class1, typically having ~100 objects for a given session. I would like to see if the list has a particular object. ASP.NET 2.0 allows me to do this: Dim objResult as Class1 = objList.Find(objSearch) How does this approach rate when compared to a traditional For loop, looking at a performance perspective? How would this vary with increase or decrease in length of the list?

• How to create a generic Android XML layout for all activities

  I have an application that needs the same items [5 buttons acting as tabs] in every screen. Is it possible to create a "base XML layout" that has these 5 buttons and then have all the other XML files extend from the bas layout in some way so that I don't have to have multiple buttons that will ultimately have the same functionality. Is there a better approach to this problem that can be supported by API 9

• dropping characters from regular expression groups

  - by tcurdt

  The goal: I want to convert a number from the format "10.234,56" to "10234.56" Using this simple approach almost gets us there /([\d\.]+),(\d\d)/ => '\1.\2' The problem is that the first group of the match (of course) still contains the '.' character. So questions are: Is it possible to exclude a character from the group somehow? How would you solve this with a single regexp (I know this is a trivial problem when not using a single regexp)

• How to hook onclick event for each cell in a table in Javascript?

  - by MartyIX

  I was thinking if there's a better solution for adding onclick handler to each cell in a table than this approach: http://stackoverflow.com/questions/1207939/adding-an-onclick-event-to-a-table-row Better in the way that I wouldn't need to set "cell.onclick = function" for each cell. I just need to get the coordinations of a cell where user clicked. Thanks!

• Fast way to compute the minimal distance of two sets of k-dimensional vectors

  - by vrld

  I two sets of k-dimensional vectors, where k is around 500 and the number of vectors is usually smaller. I want to compute the (arbitrarily defined) minimal distance between the two sets. A naive approach would be this: (loop for a in set1 for b in set2 minimizing (distance a b)) However, this requires O(n² * distance) computations. Is there a faster way of doing this?
