I found out what the problem is .

When getting an element from the wrapper set ( by index array notation or by get(index ) ), it returns a javascript element , NOT a jquery object and thus...

Hey guys ,

While playing with jquery i've come across the following situation :



$(document).ready(function(){

$("div")[0].css("background-color","blue");
});

This helped a lot , thanks Aia . You're great .

Hi guys ,

In Visual Studio 2005 I compiled the following code

int main()
{
float a;
a=0.1;

if(a<0.1)

I assume you have a single form , with lots of input of type checkbox.
In this case , what you can do to avoid the if/else avalanche is to loop through the $_POST array , and make a single if...

No , I just needed a very simple post quick reply implementation on the viewtopic.php in phpbb 2.0
I found a mod that does exactly what I need .Stupid me , I googled for "short message reply" mod ,...

How can I have a post quick reply textarea , just like the one on daniweb , in a phpbb 2.0 ?
Do you know/have a mod that does that ?

This code gets the today's gas price
It's easy to get it on this site because the price is placed between a span with the id "GBPS_lblUSToday"

$arr = file("http://www.gasbuddy.com/");
...

in the $header,make sure you have a space after From:

$headers="From: Mycompany asdfa@asfa.com";

If the user input is ,for example "house Seattle job" and you wanna get the Seattle word, you can do this with explode http://www.php.net/manual/en/function.explode.php

php if($_GET['KEY'] == "")...

U can use the array_search() function
http://www.php.net/array_search
Make sure u use the "===" for comparising.
It should look something like this :

if ($NewVersionFlag==0)
{
$i=0;

Dude , have you read at least one php book ????

Some advice :
1.Always test if the file exists , first :

if(!file_exists("to.txt"))
die("File could not be found");
2.

$names[$x] = fgets($sub);

I assume you are...

LOL
It's because on your laptop you have a database with a table admin(or whatever you name it ) which contains the info to be checked when a user tries to log in .

Are you sure you don't have a closing php tag( ?> ) somewhere ?
Type phpinfo(); at the line where it crashes ,to see if the interpreter works at that point( although I'm pretty sure it won't)

I have a list of users(signed for a newsletter).I'm retrieving the list from a database when the admin clicks on a button.
There are maximum 10 users diplayed per page.For example,if I had 30 users...

First of all , you must get the hole html content of the page in an array.U can do that with the file() function an example :

$arr=file('http://www.yahoo.com');

This is a very famous error in php . If you echo something , before the header function you'll get an error because the "channel" was occupied by echo.You need to put the header before any echo's or...

It's better if you leave it off . Imagine how easy is for someone to hack your code .This is the reason why the developers set the register_globals off by default from php 4.2 . Instead u can use...

My teacher wrote that sample code , and yes,is bad formatted,but he's not so bad ; at class , he explaines very well and he's one of the few teachers who really knows about modern programming

I've used wamp 1.5.0 , 1.5.0.a , 1.7.1 , 1.4.2
All of them have the short_open_tag = Off by default , and I guess that all future versions will have this as well
It can be really frustrating.

Hey thanks :) It worked . You we're right ,it was that short_hand thing.

You're the best

As Snoop Dog would said , fo'shizzle :cool:

Here's the header file :


#ifndef SET_H
#define SET_H

#include <iostream>

I have a class , named Set,and I want to overload the operator - so I can get the difference between 2 Set object.
i.e. A={1,2,3,4} , B={ 3,4,5,6} , A-B={1,2}

In header file I declared the...

U forgot to put the ampersand at age.It should look like this scanf("%d",&age)
btw,u might wanna declare variable age first.

You were right.It was that time variable :cheesy:

Thanks Ancient Dragos,Ravalon

#include <stdio.h>
#include <time.h>
#include <dos.h>

int foo()
{
int x=0;
while(x<1000000)
x++;
return x;

Well for the second example , I get " error C2064: term does not evaluate to a function taking 1 arguments" at the start and end temp(0) :sad:

After you said , at the first method ,i came up with this:

#include <stdio.h>
#include <time.h>


int foo( clock_t* time)
{
int x=0;
while(x<1000000000)

I have one or more functions separate from main() , that besides the return value , must also return the time it tooked to process.
How can I do that ?

Well,the hole project is strongly recommended for the use of static allocation and the insert ,delete must be made as a circular queue .
So i got a circular queue :


#include<stdio.h>...

I've chose to use an array just so i can make it easier.

Imagine this : You have 3 different arrays,separate from each other.
Let's say we must get a product name from the user(product name will...

Almost.The free space when one part gets full,is associated to the full one,thus increasing in size .In other words the data inserted into the free space when one part is full , becomes part of the...

This is what I got so far

#include <iostream>

using namespace std;

int main()
{
int v[90];
