Hi!
Is there a straightforward way of determining the number of decimal places in a(n) integer/double value in PHP? (that is, without using explode)
Thanks,
Erwin
Hi,
I do have two buttons
'btnPrev' and 'btnNext'
What I want to do is to be able to determine the number of clicks of the button so that I could enable and disable them. The process is almost similar to 'paging' method.
Initial state: btnPrev - disabled, btnNext - enabled
1st Click (btnNext): btnPrev - enabled, btnNext - enabled
2nd Click (btnNext): btnPrev - enabled, btnNext - enabled
3rd Click (btnNext): btnPrev - enabled, btnNext - disabled
the idea is almost the same vice-versa (for btnPrev)
any suggestions how to do it?
I'm using a jQuery plugin called InfiniteScroll (https://github.com/paulirish/infinite-scroll) and I have a URL with this pattern: '/category/2/', when I paged the result I use the following pattern: "/category/2?page=2".
When Infinite Scroll makes de request, he increments the wrong number, in the case above, the request is: "/category/3?page=2" in place of "/category/2?page=3".
Anyone knows how workaround this?
In the following short program:
use Template;
my $template = Template->new (INCLUDE_PATH => ".");
$template->process ("non-existent-file")
or die $template->error ();
why does "die" not produce a line number and newline? Output looks like this:
$ perl template.pl
file error - non-existent-file: not found ~ 503 $
My JSON looks like this:
{
"[email protected]":"Person1",
"[email protected]":"Person65",
"[email protected]":"Person24"
}
It's returned in various number of elements, and various keys. How do I traverse the data if my code is like this:
$.post("includes/ajax.php", {
group_id : $('#group').val()
}, function(data) {
//how do i traverse data here?
}, "json");
Any help will be appreciated :)
Thanks!
Is there a limit to the maximum number of concurrent users connected to SQL Server 2008? I am guessing computer resources determine that limit (if it exists), but I am also wondering if there is a theoretical limit. I have tried googling the answer, but all the information I have found is based upon earlier versions of SQL Server. If there is a limit, does it apply to just a database or a SQL Server instance?

I need to use VBA to determine the number of arguments passed to an Excel formula. For instance, suppose a cell contains the formula =MyFunc($A$1, "xyz", SUM(1,2,COUNT(C1:C12)), IF(B12,1,0)). Then the counter function should return 4. Does VBA contain any built-in functions for this, or does someone have an example of a regular expression that could calculate this?
Hi,
I'm trying to figure out how I can convert a number between 1 and 50 to a greyscale color that could be used here:
g.setColor(MyGreyScaleColour);
1 would be lightest (white) and 50 would be darkest (black).
e.g.
Color intToCol(int colNum)
{
code here
}
Any suggestions?
I am using C and Grand Central Dispatch to parallelize some heavy computations. How can I get the number of threads used by GCD? Also is it possible to know on which thread a piece of code is currently running on? Basically I'd like to use sprng (parallel random numbers) with multiple streams and for that I need to know what stream id to use (and therefore what thread is being used).
Hello,
I would like a regular expression in this format. It Must match one of the following formats:
* (###)###-####
* ###-###-####
* ###.###.####
* ##########
Strip all whitespace. Make sure it's a valid phone number, then (if necessary) translate it to the first format listed above.
I'm developing a simple web application where in I need to display number a to my users in string format.

I am trying to get to grips with BDD web development in Ruby using cucumber + capybara and I am stuck at what should be an easy task - just to check the number of rows in a table. Something along the lines of:
page.should have_xpath("//table[@id='myTable']")
find("//table[@id='myTable']/tr").length.should = 3
But this doesn't work and I can't find a way to assert against the table length.
Any ideas anyone (please be easy on me tho' I'm a ruby nooby)
Thanks in advance

The question is that i need some methods/ideas for writing a number N in basis M, for ex. 14 in basis 3 = 2*(3^0) + 1*(3^1) + 1*(3^2) etc.

I am trying to get the total count for the phone numbers listed in the AddressBook, in all groups as a whole.
I can successfully retrieve Person count and Group count, just not the total number of Phone Numbers.
ABAddressBookRef m_addressbook = ABAddressBookCreate();
CFIndex nPeople = ABAddressBookGetPersonCount(m_addressbook);
CFIndex nGroups = ABAddressBookGetGroupCount(m_addressbook);
I have hierarchical data that I represent using the adjacency list model.

Thanks for your advice!
