This may be a completely dumb question, but I've seen a couple examples declaring the variables AFTER putting them in bind_param:
http://devzone.zend.com/article/686
I've never seen this done before and all my programming knowledge says I should define them before hand. Is this a valid/preferred way?
I want to define a function replicate to replicate a list of numbers by its value using only list comprehension, for example:
replicate [5,1,3,2,8,1,2]
output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2]
I know this would be easy to use the 'replicate' built in function but only list comprehension is allow, how can I do this?
THANKS!
Basically I want the books to be text book based, ie, author discusses the background,philosophy,syntax,semtantix for every language AND after every section there are questions what you learned so far and mini projects. Is there any books like this, I'm absolutely new to php/mysql/javascript and web development in general. Thanks in advance.
I'm trying to access the number in the below element, but I'm having trouble getting the value out of it.
echo $object->0; //returns Parse error: syntax error, unexpected T_LNUMBER, expecting T_STRING or T_VARIABLE or '{' or '$'
SimpleXMLElement Object (
[0:public] => 15810
)
Any ideas on how I can get that value?
Hello,
I have a strange problem which I can't fix:
A field:
private boolean[][][] gaps;
Constructor (1st line):
gaps = new boolean[NOBARRICADES][WIDTH][HEIGHT];
Constructor (2nd line):
for (int i = 0; i < NOBARRICADES; i++) {
JAVA throws an error for the 2nd line, saying:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
Does it have anything to do with JAVA syntax (the mistake is in these lines of code) or I should look for the problem somewhere else?
I am in search of a programming language with the below characteristics:
it has existing, large and supportive/helpful community
it has consice syntax
it's fast
it can create standalone apps with no dependencies, totally portable and compatible with windows
I can easily set event listeners of almost anything
I can easily do automatically every action possible
has as extensive as possible ready-to-use commands list
works easily with winxp, win com, firefox, etc api
for example, I want to detect that I have clicked a specific button in a webpage in firefox or in a third-party app in windows:
I want to do this easily, not with writing 100 lines of code
I have this snippet of the code
Stack& Stack:: operator=(const Stack& stack){
if(this == &stack){
return *this
}
}
here I define operator = but I can't understand, if I receive by reference stack why it should be & in this == &stack and not this == stack and why we return * in return *this and not this thanks in advance for any help
I am familiar with impersonating an account in .net by using:
dim myIdentity as WindowsIdentity = someIdentity
using ctx as WindowsImpersonationContext = myIdentity.Impersonate()
doStuff()
end using
Is it possible to define a .net attribute so that I could write something like:
< runAsUser(someIdentity) public sub doStuff()
and then have the .net framework always impersonate when running the method doStuff()?
Suppose I have a class A and a class B.
The .h of A, needs the .h of B, and the .h of B needs the .h of A. (need = #include).
All .h have the guards:
#ifndef _classX_
#define _classX_
...
...
#endif
But if I compile the .cpp of A, then when it includes the .h of B, the B class cannot include the .h of A class because the A class has already use the guard.
How can i solve this?
Not quite sure how to ask or define this, but can't figure it out.
I have three tables like this:
persons person_id, first_name, last_name
hobbies hobby_id, name
persons_hobbies person_id, hobby_id
I need to make two lists. Persons that have both hobby A and B, and persons that have hobby A but not B. How can I write these two queries? Can't figure out how to do this with joining and all...
The copy assignment operator has the usual signature:
my_class & operator = (my_class const & rhs);
Does the following signature have any practical use?
my_class const & operator = (my_class const & rhs);
You can only define one or the other, but not both.
Hello,
I'm currently trying to make an AppleScript which should recognize the selected file in Finder and do the relative command in Terminal.
Everything was going fine since I reached the part where it should define the language of the selected file: it just doesn't check the ifs.
I checked if it writes fileExtension correctly (via return) and it does.
Here is the
Gist with the code, any help would be appreciated.
Thanks

Is there any way to define a variable that can be used in multiple Web pages? For example, a string variable stores a certain value in page A and that value can be accessed in page B. I know cookies can do it. Is there any other way?
If i have a function api that expects a 14 digit input and returns a 6 digit output. I basically define the input as a const char *. would that be the correct and safe thing to do?
also why would I not want to just do char * which I could but it seems more prudent to use const char * in that case especially since its an api that i am providing. so for different input values I generate 6 digit codes.
hello, im trying to delete a foreign key with the following syntax (5.0.45-community-nt):

but I'm getting the folling error:

any ideas?
thanks!
I have two different areas, and I have a route in one of those areas that is specific to that area, but I need to generate a link to that route using Html.RouteLink from another area (it's how you get over into the new area) but it won't work... It doesn't seem possible to use RouteLink to routes in a different area.
What is the best way around this? Should I just define a new route in the other area and name it differently?
I "accidentally" came across this weird but valid syntax
i=3
print i+++i #outputs 6
print i+++++i #outputs 6
print i+-+i #outputs 0
print i+--+i #outputs 6
(for every even no: of minus symbol, it outputs 6 else 0, why?)
Does this do anything useful?
Update (Don't take it the wrong way..I love python):
One of Python's principle says
There should be one-- and preferably only one --obvious way to do it. It seems there are infinite ways to do i+1
I need to put a map in a webpage and I need that when the users clicks on certain area inside city limits on the map the user is redirected.
Wich is the best way without using Flash?
Define Hover polingons on a image.
SVG on the browser.
Some sort of Javascript, jQuery magical plugin out there?
Google Maps?
And example could be this but It's flash.
Hi,
I was told the array name is a pointer
char a[] = "a"
but when
sizeof(a) = 2
why not it is a size of pointer here?
however when I define it like this
char* a ="a";
we get
sizeof(a) =4;
Well, I think I need more information about how does sizeof work with the array names....
Can anyone elaborate that?
