I want to know from where the index of a string and an array starts from.
I am getting a lot of confusion while making programs.
While calculating string length of a string is the null character also counted.
I have upgraded my application from rails 2.3.8 to 3.0.3 . But I'm facing a problem. I was using 'find' but the overriding doesn't work in rails 3:
# override activerecord's find to allow us to find by name or id transparently
def self.find(*args)
if args.is_a?(Array) and args.first.is_a?(String) and (args.first.index(/[a-zA-Z\-_]+/) or args.first.to_i.eql?(0) )
find_by_login_slug(args)
else
super
end
end
I'm wondering if there is a way to make this work in rails 3 or even by using where instead.
thanks
Hi,
i have this line:
<?php include_component('sfGuardRegister', 'register') ?>
when it's executed i get a blank page. I have debugged include_component() and the flow processing is not entering inside of it, i mean:
function include_component($moduleName, $componentName, $vars = array())
{
die("enter");
echo get_component($moduleName, $componentName, $vars);
}
Any idea?
Hi,
I need a C# function that takes 2 strings as an input and return an array of all possible combinations of strings.
private string[] FunctionName (string string1, string string2)
{
//code
}
The strings input will be in the following format:
String1 eg - basement
String2 eg - **a*f**a
Now what I need is all combinations of possible strings using the characters in String2 (ignoring the * symbols), and keeping them in the same character position.
Eg: baaement, baaefent, baaefena, basefent, basemena, etc
any help? :)
Hello all!
I was thinking if there such a function for c language.
I have a char array with data from a text file and i need to convert it to hexadecimal format.
Thank you in advance!
I'm rubbish at Regular Expressions, really!
What I'd like is to split a string containing a CCS property value into an array of [string,value,unit].
For example: if I supplied the .split() method with 1px it'd return ["1px",1,"px"]. If I were to supply, similarly, 10% it'd return ["10%",10,"%"].
Can this be done?
I appreciate all your help!
Hi,
How can i addition one + one matric (array data structure) and after it find the third smallest number in it in C language (not C++)? Thank you for the code.
I have several entries in a table with name and date. I'd like to fetchAll with Zend_Db then get a grouped-by-date array. It happens that if I use group(), Zend_Db_Select method, it excludes some entries and I need them all.
Actually, what I'm trying to do is to render several tables, one for each different date, with data inside. I have no ideia.
How do I do that?
Thx in advance
For example, lets say I have this string:
"Name, Name2, <b>Name3</b>, Name4, <b>Name5</b>"
I am trying to get whatever value / name is inside the <b> tags. So when I search the char, I get the following in an array:
Name3
Name5
Any ideas? Thanks
can anybody explain me what will be equivalent of this in java?
for (i =(sizeof(num)*8-1); i; i--)
num is given number not array i want reverse bits in integer
Is there a way to add files to a zip file from another server with php's zip extension? ie. addFile(array('localfile.txt,'http://www.domain.com/remotefile.txt')) (that obviously does not work)
I suppose I can download the files to a temporal folder and then add them to the zip file, but I was looking for a more automated solution or a function already made
Does Ruby have an equivalent to .NET's Encoding.ASCII.GetString(byte[])?
Encoding.ASCII.GetString(bytes[]) takes an array of bytes and returns a string after decoding the bytes using the ASCII encoding.
I am calling this function which is modifying an array by reference:
function addWord(&$words, $wordIndex, $word)
{
$words[$wordIndex] = $word;
}
At the function call,
addWord(&$words, $wordsIndex, $word);
($words is used only during the function call)
doesn't work. How do I make this or a similar functionality work? I want the addWord to be a separate function.
Hello,
is their any way to make this work, without sacrificing the cdef in cdef caller? (no use of cpdef either)
from array import *
from numpy import *
cdef class Agents:
cdef public caller(self):
print "caller"
A[2].called()
cdef called(self):
print "called"
A = [Agents() for i in range(2)]
def main():
A[1].caller()
I really wish that Google was better at searching for syntax:
decades :: (RealFrac a) => a -> a -> [a] -> Array Int Int
decades a b = hist (0,9) . map decade
where decade x = floor ((x - a) * s)
s = 10 / (b - a)
what is the C++ equivilant to the c function fgets?
I have looked at getline from ifstream, but when it comes to a end of line character, '\n', it terminates at and discards it, I am looking for a function that just terminates at the end line character but adds the end of line character to the char array.
thanks in advance
In PHP I could echo data to the web browser to debug.
eg. echo print_r($array)
How do I do that in RoR? I tried with puts with no luck.
Is there a way?
I have a largish array of string that I want to use as a lookup.
I a using in_array(), but I suspect its doing a simple loop through - does anyone know whether the in_array() algo uses a bsearch algo?
Hi
i need a function that should give me a 10th or 100th array, for example
if i pass 5, it should return 1 to 10
if i pass 67, it should return 1 to 100
if i pass 126, it should return 101 to 200
if i pass 2524, it should return 2001 to 3000
Any guidance?
I run through a for loop, each time extracting certain elements of an array, say element1, element2, etc. How do I then pool all of the elements I've extracted together so that I have a list of them?
Under these conditions,
The o/p of the first program is an large array of either integers, doubles or strings.
Best method means the fastest on x86 architecture.
I want Pi to like 100,000,000 decimals/digits...
And variables (well for me) say they have a limit of 67,000,000 bytes...
Is there any way around this?
can you save the first 10,000 characters/digits into one?
can you save it into an array 10,000 in each?
Is there a way?
If so how? Thanks alot...
