Hi,
Can someone please let me know by some code how I can call a function located in the Form class from another class?
Some code will be of great help!
thanks
abstract class db_table {
static function get_all_rows() {
...
while(...) {
$rows[] = new self();
...
}
return $rows;
}
}
class user extends db_table {
}
$rows = user::get_all_rows();
I want to create instances of a class from a static method defined in the abstract parent class but PHP tells me "Fatal error: Cannot instantiate abstract class ..." How should I implement it correctly?
Hello,
I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly.
The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power.
Clashes are not a problem.
I'm using javascript, so it shouldn't be too complicated to implement.
I'm using the JQuery autocomplete plugin. I wish to override the implementation of the filllist() function. Can someone point me to an example of how to do this?
hi.
I have a multiple file upload form(html5) and want to update my view as soon one of the images is transfered to my image server.
Currently I upload the files with ajax and use response_to_parent to update my upload view when all images are transfered to the image server.
Is it possible to call a Javascript function from the controller more than once per action?
def upload
params[:images].each do |file|
upload_to_image_server(file)
#page << Update upload View
end
end
Thanks,
Michael
Code Sinnpet:
int CreateaTCPSocket()
{
int iSockID = ACE_OS::socket(......);
ACE_OS::set_flags(iSockID,O_NONBLOCK);
ACE_OS::bind();
if (ACE_OS::connect(iSockID ,....) < 0)
{
if (ACE_OS::select(.....,timeout) <= 0)
{
return INVALID_HANDLE;
}
}
return iSockID;
}
My question is when connect is failed for non-block error and select is called and say select return success then again we need to call connect or select function internal do connect?
I'm trying to write a function :
Input:
Source range, Source value, output range, curve type (Linear, smooth)
Output:
The output is the "source value" converted into the "output range"
according to the curve type.
I hope I am making sense here...
Any ideas ?
Thanks.
I'm new to PHP and I'm confused seeing some examples calling a function with a @ prefix like @mysql_ping().
What is it for? Googling / searching is not much of a help since @ gets discarded and 'alias' is not good enough keyword.
I have problem querying table with variable in IN function.
SELECT
s.date,
(SELECT
GROUP_CONCAT(value)
FROM value
WHERE id_value
IN(s.ref_values)
)
AS vals
FROM stats s
ORDER BY s.date DESC
LIMIT 1
Where s.ref_values is '12,22,54,15'. I get only one return for first number (12).
When I insert that value directly in IN(12,22,54,15) it finds all 4.
So, there must be problem with using variable in IN. What am I doing wrong?
Hi Stackoverflow,
I have been looking at the source code of raphael (http://raphaeljs.com/index.html) and I see a lot of stuff like !variable && function() (e.g.: !svg.bottom && (svg.bottom = this); )
What does that exactly do? Does it check first and execute only if not true?
Thanks.
Hi all
I have a string with file content .
But my function deals with file path on the disc .
Any idea how i can solve this problem without writing to the disc my file content ?
Thanks for help.
Hi everyone im new to a PHP framework codeIgniter, I am going over the user guide iv ran in to a problem, I am on the part where you load helper file but for some reason my code just isnt working I keep getting this error:
Fatal error: Call to undefined function anchor() in /home/fresherd/public_html/CI/system/application/views/blogview.php on line 17

any advice will help many thanks, Alan
Pandas has the following indexers:
Object Type Indexers
Series s.loc[indexer]
DataFrame df.loc[row_indexer,column_indexer]
Panel p.loc[item_indexer,major_indexer,minor_indexer]
I would like to be able to index dynamically by axis, for example:
df = pd.DataFrame(data=0, index=['row1', 'row2', 'row3'], columns=['col1', 'col2', col3'])
df.index(['row1', 'row3'], axis=0) # index by rows
df.index(['col1', 'col2'], axis=1) # index by columns
Is there a built-in function that does this?
I have following code:
static __inline__ LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
After compilation I got following warning:
inlining is unlikely but function size may grow
I removed the inline and changed into the following :
static LIST list_List(POINTER P)
{
return list_Cons(P,list_Nil());
}
Now I get the following warning:
list_List is defined but not used.
Can anybody please suggest me how can remove that warning.
The error-Warning: sqlite_query() [function.sqlite-query]: attempt to write a readonly database is coming whenever i try to insert values into a sqllite 1.1 database thru php program.
php version is 5.2.
Can I pass arrays to functions just as I would do with primitives such as int and bool?
Can I pass them by value?
How does the function know of the size of the array it is passed?
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp\htdocs\program\sanweetha\quotation.php:280) in C:\xampp\htdocs\program\sanweetha\php\captcha demo\captcha_demo.php on line 1
I need to pass two array list references to a function and return the reference of merged array list.
how can i do it????
pls help....
public int merge(ArrayList x, ArrayList y)
{
List all = new ArrayList();
all.addAll(x);
all.addAll(y);
System.out.println(all);
return all;
}
is it correct???
I don't know how feasible it is and how sensible is this question here.
Is there any changes that we can make in makefile to recommend GCC inline all the function although the functions are not inlined during the declaration or nowhere in the source file.
This is in the context of a local Processing program. I would like to run an external program to get some data. Is there a popen() or equivalent function I can use?
Is there a difference, performance or efficiency wise, between placing javascript calls such as blur, onclick etc. in $(document).ready(function(){ as opposed to placing them in DOM?
Thanks!
