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
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.
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.
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.

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?

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
now im not 100% sure that it is loading the helper file this could be causing the but I am not sure how to detect the file has been loaded
any advice will help many thanks, Alan
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.
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?
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.

});
There seems to be an error .

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?
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?
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!
I've been searching examples for the Win32 API C++ function TerminateProcess() but couldn't find any.
I'm not that familiar with the Win32 API in general and so I wanted to ask if someone here who is better in it than me could show me an example for,
Retrieving a process handle by its PID required to terminate it and then call TerminateProcess with it.
If you aren't familiar with C++ a C# equivalent would help too.
Hi,
I have a recursive function that is designed to take parse a tree and store all the values of the tree nodes in an NSString.
Is the algorithm below correct?
NSString* finalString = [self parseTree:rootNode string:@""];
-(NSString*)parseTree:(Node*)currentNode string:(NSMutableString*)myString
{
[myString appendText:currentNode.value];
for(int i=0;i<[currentNode.children length];i++){
return [self parseTree:[currentNode.children] objectAtIndex:i] string:myString];
}
}
