Hi, I need to implement List decorator class, which notify registered listeners in case of any change in list. I have subclassed AbstractListDecorator from org.apache.commons.collections15 and override methods like add(), addAll(), remove(int), remove(E) and so on with my notifying. But there are some holes in -- for example when iter...
I have a custom event handler on a wiki page, which should add a Tag to a custom coloumn which I attached to the Users List. The problem is how can I obtain a reference to the List in a event. It doesn't seem to be in the Profile of the profile manager and accessing it with Spweb.Lists["Userinformationlist"] gives me an error for non Adm...
I am using a List to hold some data obtained by calling Array.asList() method. Then I am trying to remove an element using myList.Remove(int i) method. But while I try to do that I am getting an UnsupportedOperationException. What would be the reason for this? How should I resolve this problem? ...
I'm new to MVC and C#. I'm trying to get a static list to work with a DropDownList control such that the selected value rendered is set by the current Model value from the DB. In the controller, I have: ViewData["GenderList"] = new SelectList(new[] { "Female", "Male", "Unknown" }, donor.Gender); In the view: Gender:<%=Html.DropDo...
I'm just starting with programming. I have a list of a few strings and now I need to print the biggest (in length) one. So I first want to just print the lengths of elements. I was trying things like this: l = ("xxxxxxxxx", "yyyy","zz") for i in range(len(l): So how do I do it? ...
In Mathematica I have a list: x = {1,2,3,3,4,5,5,6} How will I make a list with the duplicates? Like: {3,5} I have been looking at Lists as Sets, if there is something like Except[] for lists, so I could do: unique = Union[x] duplicates = MyExcept[x,unique] (Of course, if the x would have more than two duplicates - say, {1,2,2,2...
Trying to figure out the best way to set up collection "lists" for users given the following data (pseudo code): user table = id, name, email cars table = id, make, model user_cars table = user_id, car_id, rating collections table = id, user_id, name Facts: Users can have many cars Users can have many collections Individual cars ...
Hello guys. I need to construct a tool that will be used to create field mappings (between tables) in the most automated manner possible. Here is the deal: imagine a table being appended to other. (lets ignore field type, just for a second...) CREATE OR REPLACE TABLE fooA( id, name, type, foo) CREATE OR REPLACE TABLE otherFooTable( i...
I have a seemingly simple problem whereby I wish to reconcile two lists so that an 'old' master list is updated by a 'new' list containing updated elements. Elements are denoted by a key property. These are my requirements: All elements in either list that have the same key results in an assignment of that element from the 'new' list...
Hi; I feel my question is pretty dumb, or another way to put it is : I'm too lost in my code to see a workaround for now. Stay too long on a problem, and your vision becomes narrower and narrower ><. Plus I'm not good enough with inheritance, polymorphism and so Here is the idea : I have multiple list of derived class, and I would like...

l = range(100) for i in l: print i, print l.pop(0), print l.pop(0) The above python code gives the output quite different from expected. I want to loop over items so that I can skip an item while looping. Please explain. ...

I can't seem to find an elegant way to start from t and result in s. >>>t = ['a',2,'b',3,'c',4] #magic >>>print s {'a': 2, 'c': 4, 'b': 3} Solutions I've come up with that seems less than elegant : s = dict() for i in xrange(0, len(t),2): s[t[i]]=t[i+1] # or something fancy with slices that I haven't figured out yet It's obviously ...
I have a column, B, that is calculated based on another column, A. At the top of the list, I'd like to display the sum of B. When I look in the Totals section in the Create/Modify a Column screen, I only see column A (actually, I only see all the non-calculated columns), so I can't choose to sum column B. Is there a way to display a tot...
I have a long UL list I need to break up in smaller lists containing about 20 items each. I was thinking I could use something like $(function() { $("ul li:nth-child(20n)").after("</ul><ul>"); }); but that's not the case. Any idea how to use jQuery in a way that uses minimal CPU? Thanks ...
Hi guys! I'm developing a J2ME application, and I need to show a .png picture, then right beneath it, a list of strings from which the user can select one. Since you can't append an image to a List, I tried using a Form, appending an ImageItem to it, then appending an ChoiceGroup with the options. This works very well on the Sun WTK emu...
Hi, I have my custom content type, and list definition.

My list look as :- Also i tried added a...
I have a list of lists that looks like this: x[[state]][[year]]. Each element of this is a data frame, and accessing them individually is not a problem. However, I'd like to rbind data frames across multiple lists. More specifically, I'd like to have as output as many dataframes as I have years, that is rbind all the state data frames ...
Hello, I was trying to use an STL list in C++ and I arrived into a strange exception that I'm not able to understand. The list is defined as list<ASTNode*> m_stats; and ASTNode* is a class. When I try to add elements by calling ASTNode *node = new ASTNode(); m_stats.push_back(node); it throws the following exception: Program receive...
