I'm developing a Ruby on Rails app where one of my database tables has 10 columns (pile_1 through to pile_10). It would be convenient to access these columns in the model as a 10-element Array. It feels like I should be able to coerce composed_of into doing what I want, but I can't figure out how. Can anyone enlighten me, or suggest a b...
I have an array of various things including scalars and arrays. I want to make a copy of it, and tried the following: @b = dclone(\@a) but then when I try to read one of the scalar values from b, I get nothing back. Everything appears to work when I copy it this way, though: @b = @{dclone(\@a)} What is the reason? ...

However, there is something wrong with this code I cannot identify: for(x in array) { if(array[x] instanceof Array) { array[x] = array[x].join("`"); } } var string = array.join("@"); localStorage[key] = string; Doe...
This is related to my question asked here today on SO. Is there a better way to build a packet to send over serial rather than doing this: unsigned char buff[255]; buff[0] = 0x02 buff[1] = 0x01 buff[2] = 0x03 WriteFile(.., buff,3, &dwBytesWrite,..); Note: I have about twenty commands to send, so if there was a better way to send the...

Hi, I am using dictionary for storing ID,otherID and bool value. Unfortunately it compares array reference, therefore I cannot use it. Is there any way how to have an array as key but compare its values instead of reference? Thanks ...
I'm trying to create "related articles" for our news, based on tags (single word tags). If a story is tagged with 3 tags, I'd like to be able to pull up the most recent entries for each tag, order them by date, and display only the most recent 5. Here's what I'm trying, that obviously doesn't work, because it overwrites the array varia...

The website I am working on will contain a drop-down list that shows a number of reason codes. Is it possible to populate a drop-down list with an array derived from a custom class?

I have a large table of N items with M (M>=3) distinct properties per item, From this table I have to remove all items for which the same table contains an item that scores equal or better on all properties. I have an algorithm (python) that solves it already, but it is output-sensitive and has a worst case of approx. O((n²+n)/2) when n...
I am passing an empty char array that I need to recursively fill using strcat(). However, in the VS debugger, the array is not empty, it's full of some weird junk characters that I don't recognise. strcat() then appends to the end of these junk characters rather than at the front of the array. I have also tried encoded[0] = '\0' to clea...
Ok, I'm really confused by this behaviour in VS2008. This code.. char data[512] = ""; char c[1] = ""; c[0] = '1'; strcat(data, c); .. results in data being set to this string value: 1ÌÌÌÌhÿ Surely it should just be 1? How can I ensure data only contains the single char[] that I copy into it (i.e. 1)? Why does strcat() copy all t...
is it possible to make stdClass objects work like a generically indexed array? i.e. $array = Array ( [0] => 120 [1] => 382 [2] => 552 [3] => 595 [4] => 616 ) would be constructed like $a = array(); $array[] = 120; $array[] = 382; etc. but if i do that with an object it just overwrites itself: $obj = new stdClass; $obj->a = 120; $...
I am trying to use an Array instead of a list in my query. But I must get the count first before I can iterate through the objects returned from the database. Here is my code: var FavArray = favorites.OrderByDescending(y => y.post_date).Skip((page - 1) * config.MaxRowsPerPage).Take(config.MaxRowsPerPage).ToArray(); int F...
I quickly jotted off a Perl script that would average a few files with just columns of numbers. It involves reading from an array of filehandles. Here is the script: #!/usr/local/bin/perl use strict; use warnings; use Symbol; die "Usage: $0 file1 [file2 ...]\n" unless scalar(@ARGV); my @fhs; foreach(@ARGV){ my $fh = gensym; ...
