Just a small question here, that how do we get fetch the html content via ajax into a variable that I could use later.
Right now, I have a button on the click of which, I fetch another html page simply through load method as follows:
$('#container').load('http://127.0.0.1/someUrl')
I want to get the content into a var instead that I could at a later time use to append to the dom $('#someContainer').append(someVar)
I am trying to understand the difference between this:
if (isset($_POST['Submit'])) {
//do something
}
and
if ($_POST['Submit']) {
//do something
}
It seems to me that if the $_POST['Submit'] variable is true, then it is set. Why would I need the isset() function in this case?
Hi,
I'm needing to build multiple environments and tag them in subversion using a nant script. Is there a way that I can use nant to create the tags in svn with a variable I supply?
Thanks.
I like to use 'this' statement for all non-local variables: for properties, for class variables, etc. I do this for code easy reading, easy understanding where from this variable has got.
object someVar;
object SomeProperty { get; set }
void SomeMethod(object arg1, object arg2)
{
this.SomeProperty = arg1;
this.someVar = arg2;
}
How do you think, what is proper way to use 'this'?
Hi
As i know, all the threads share memory location. For example a global variable changes in one thread will reflect in another thread. Since each thread has its own stack, the local
variables that are created inside the thread is unique. In this case, why do we need
to go for thread specific data mechanism?. Can't it be achieved by auto storage varibles
inside the thread function ?
Kindly clarify!!!.

I am writing a python script that downloads a file given by a URL. Unfortuneatly the URL is in the form of a PHP script i.e. www.website.com/generatefilename.php?file=5233
If you visit the link in a browser, you are prompted to download the actual file and extension. I need to send this link to the downloader, but I can't send the downloader the PHP link.
How would I get the full file name in a usable variable?
I want to display a login view to my users if they are not logged in and the main view if they are.
In my header file I define a variable to hold the logged in status
#define loggedIn 0
I figure I should then reference this in the initWithNibName method and then decide which nib to load.
Is the right way of doing it?
If so can someone help me out with the exact code?
Thanks for any help
What is the equivalent of Java's final in C#?
EDIT: Sorry, I should have been clearer. I meant what is the equivalent when applied to a member variable - so it must be assigned once and only once.
Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here).
Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor?
Can traits be used to check the constructor presence?
If yes, how?
If not, why it is not possible?

The scenario is as follows:
Create an instance of a class (std::map) and
sore it as global variable.
Spawn threads.
Threads read and use the same global
instance of the class
All spawned threads quit
Global class instance is destroyed
No mutex, no thread modifies the global class instance.
Is it ok?
Thank You
Ok so, Im using jQuery to do username and email checks before a signup...
this sets a variable true or false depending on the response from php.
$(document).ready(function() {
if (usr_checked == true) {
if (em_checked == true) {
$("#registerbttn").removeAttr("disabled");
}
}
else {
$("#registerbttn").attr("disabled", "disabled");
}
});
How exactly do i get it to watch those variables live?
Thanks :D
Hi, I'm just wondering how I can retrieve a specific value (only 1 thing will be returned) from a database using php.
My query is
mysql_query("SELECT balance FROM users WHERE username = '". $this->username . "'")
I'm just looking for it to retrieve the data from that row so I can save it directory into a variable.
I have the cursor with the query statement as follows:
cursor.execute("select rowid from components where name = ?", (name,))
I want to check for the existence of the components: name and return to a python variable.
How do I do that?
Hello,
I am trying to use this query to return every instance where the variable $d['userID'] is equal to the User ID in a separate table, and then echo the username tied to that user ID.
Here's what I have so far:
$uid = $d['userID'];
$result = mysql_query("SELECT u.username
FROM users u
LEFT JOIN comments c
ON c.userID = u.id
WHERE u.id = $uid;")$row = mysql_fetch_assoc($result);
echo $row['username'];
In NumPy functions, there are often initial lines that do checking of variable types, forcing them to be certain types, etc. Can someone explain the point of these lines? What does subtracting a value from itself do?
t,w = asarray(t), asarray(duty)
w = asarray(w + (t-t))
t = asarray(t + (w-w))
