I have this table (simplified):
CREATE TABLE `my_table` (
`id` INT NOT NULL AUTO_INCREMENT ,
`item_name` VARCHAR(45) NULL ,
`price` DECIMAL(10,0) NULL ,
PRIMARY KEY (`id`) )
I need to select all items from the table, ordered this way:
1. items with price > 0.00 first, ordered by price ASC
2. items with price = 0.00 last, orde...
I'm working on a parallelization library for the D programming language. Now that I'm pretty happy with the basic primitives (parallel foreach, map, reduce and tasks/futures), I'm starting to think about some higher level parallel algorithms. Among the more obvious candidates for parallelization is sorting.
My first question is, are p...
In Delphi / Pascal I would like to sort a TStringList alphabetically. But for this purpose, I can only use the following two methods:
Move: Moves a string from one index position to another, shifting other strings around as appropriate.
Exchange: Swaps two strings in the list, as identified by their index positions.
How could I do thi...
I would like to have a playlist for my own music player in Delphi / Pascal.
I thought that it would be the best solution to have a TStringList with the path of the MP3 file and - additionally - a TListBox with the song names. The matching strings in both lists must be at the same position. So if the user chooses item 5 in TListBox I can...

I've found several js table column sorters that work great on regular html content:
http://www.kryogenix.org/code/browser/sorttable/
http://www.allmyscripts.com/Table_Sort/index.html#how_to_use_it
The first one works by assigning a class to a table. The second by passing the id of the table to a js constructor.

What I am hoping to achieve is the ability to generate 'teams' of users. I will have x amount of men, weighted (decimal skill weight, like 75.23) and y amount of women (also with a skill weight value).
Given that list of users, I would then take for input the number of teams to make (let us say, 6 teams). Then, I go through the list o...
I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:
MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,

private function onDataGridResort(e:...

Hello everyone,
I was wondering whether it's possible to sort some elements first and store them (already sorted) in a varible. I would need to refer to them thought XSLT that's why I'd like to store them in a variable.
I was trying to do the following, but it doesn't seem to work
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/...
Hi !
myListBox.Items.SortDescriptions.Add(
new SortDescription("BoolProperty", ListSortDirection.Descending));
This sorting works only for string properties of the underlying project. Not with boolean? Is there a reason for that ?
Thanks !
UPDATE:
Yep, your example really works. But what's wrong on my example ?

Let's say we have a list:
a = [4, 8, 1, 7, 3, 0, 5, 2, 6, 9]
Now, a.sort() will sort the list in place. What if we want to sort only a part of the list, still in place? In C++ we could write:
int array = { 4, 8, 1, 7, 3, 0, 5, 2, 6, 9 };
int * ptr = array;
std::sort( ptr + 1, ptr + 4 );
Is there a similar way in Python?

I'm surprised that no one has asked this before here... well, at least I haven't found an answer here or anywhere else, actually.
I have a ComboBox that is databound to an ObservableCollection. Everything worked great until the guys wanted the contents sorted. No problem -- I end up changing the simple property out:

Using the distance logic from this SO post, I'm getting back a properly-filtered set of objects with this code:

if use_miles:
distance_unit = 3959
else:

Does anyone know of any tools to provide simple, fast queries of flat files using a SQL-like declarative query language? I'd rather not pay the overhead of loading the file into a DB since the input data is typically thrown out almost immediately after the query is run.
Consider the data file, "animals.txt":
dog 15
cat 20
dog 10
cat 3...
I've declared a template class MyContainer as bellow, then created an instance of it of type DataType1. The DataType1 class provides a friend function "DataSpecificComparison" which is used by std::sort to compare DataType1 objects. The program compiled and sorted correctly.
I then defined a class called DataType2, gave it a friend imp...

Is there a way to merge(union without dupes) two given lists into one and store the items in sorted way by using ONE for loop?
Also, i am looking for a solution which does not makes use of API methods ( like, union, sort etc).
Sample Code.
private static void MergeAndOrder()
{
var listOne = new List<int> {3, 4, 1, 2, 7, 6, 9, 11};

Let's say I have a list of objects:
var items = new {
new { Order = 0 },
new { Order = 1 },
new { Order = -1 },
new { Order = 3 },
new { Order = 2 },
new { Order = -1 }
};
I need to order it so that items with "Order > -1" be on top of the list ordered by Order ascending, and remaining items with "Order == -1" ...
I have an array of string keys with numeric values for use in a list of tags with the number of occurances of each tag, thus:
$arrTags['mango'] = 2;
$arrTags['orange'] = 4;
$arrTags['apple'] = 2;
$arrTags['banana'] = 3;
this is so i can display the tag list in descending occurance order thus:
orange (4)
banana (3)
mango (2)
apple (2)
