Removing an element from a list isn't working, which doesn't make any sense. Am I missing some special semantics peculiar to dealing with a Grails domain object list? In controller: def userCreate = { def workgroupInstance = new Workgroup() workgroupInstance.manager = authUserDomain flash.message = User.list().toString() ...

Hi, I have to create a large list of n elements (could be up to 100,000). each element in the list is an integer equivalent to the index of the list. After this I have to call Collections.shuffle on this list. My question is, which list implementation (either java collections or apache collections) should be used. My gut feeling is Ar...
I have a dataset of ca. 9K lists of variable length (1 to 100K elements). I need to calculate the length of the intersection of all possible 2-list combinations in this dataset. Note that elements in each list are unique so they can be stored as sets in python. What is the most efficient way to perform this in python? Edit I forgot to ...

Given the SPList.ID and a site collection (or an SPWeb with subwebs), how do I quickly find the document library with the given ID? I can recursively enumerate through all webs and perform a web.Lists[guid] on each one of them, but there might be thousands of subwebs in my case, and I'm looking for a realtime solution. If there is no ...

I have a List<> of objects that I have bound to a ListBox. I then want to bind properties of the SelectedValue to various TextBoxes. The behavior is very screwy though. When binding the Name (a string) that is used as the DisplayMember for the ListBox, it doesn't update the ListBox and if I try to refresh the binding on the TextChanged ...
I have a UL with LI's set to display horizontally. The UL has a fixed width and it's set to hide the overflow. This is so I can display my images, which are to be used in a gallery, neatly. It works and looks nice. I want to, however, use jQuery to scroll the contents of the UL rather than set the overflow property to auto and be presen...
I have a list (ListView) which which displays a lot of information, and what I want to do is get the DataItem after its DataBounded, ie on the ItemCommand event.

Hello. .NET v2 When the List has a very useful (4 me) method AsReadOnly() the LinkedList does not have such a method. Is there a way to "quickly" interface an internal LinkedList to read only from the external code? ...
Hello there, not sure this was asked before, but I couldn't find an obvious answer. I'm trying to count the number of elements in a list that are equal to a certain value. The problem is that these elements are not of a built-in type. So if I have class A: def __init__(self, a, b): self.a = a self.b = b stuff = [] ...
I'm making a WPF application that is going to have multiple skins branded in by our build system. Ideally we would like the application to list off the skins available as some builds will have one to many skins. At runtime is there a way to enumerate all the Resource Dictionaries in a specific folder? I want to avoid hard coding the ...
