prevent accidental closure of a window
I'm wondering what the best way to prevent users from accidentally closing the current window, or even navigating away from the page. The page in question is a data entry page, and since people tend to accidentally close windows, I want to add a script to pop up a confirmation box or something...- m4trix

shift array, element deleted but then comes back! huh?
I'm hoping someone can explain why an array with one element, when 'shifted' in a subroutine continues to contain one element once the subroutine finishes. Consider the following: use Data::Dumper; @arrayone = [10, [1, 2, 3]]; @arraytwo = (); $number = 10; print "OUTSIDE... -
arg! somewhat complicated mixed datastructures!
I'm sure this is simple, but I can't seem to align my thoughts right. I have a file that I'm reading into an array with a series of values. For the sake of arguement we'll say there's three numbers, then any number of other numbers. I want to store the first three numbers separately, and then... -
"Modification of a read-only value" Error. Why?
if I have this code (using on a mysql database): while (my $row = $sth->fetchrow_arrayref) { foreach (@$row) { $_ = "NULL" unless defined } my (@end) = splice(@$row, -2); print join (", ",@$row)." - ".join(", ",@end)."\n"; } it will print the first row as it should, then it gives a... -
help forming a query! :)
Ok, here's the set-up. I have two tables, for simplicty, we'll say users and staff the important fields are users.userid users.staffid and staff.staffid staff.has_user (enum('0','1')) All users must have an associated staff id (hence the users.staffid) but not all staff needs an associated... -
MSN client in perl
Anyone seen/have a working version of one? I found a couple modules, but they don't work. I think they may be outdated, but I'm not sure. -
complicated array sorting
This isn't as hard as I think it is - but I'm just not thinking right at the moment. Ok, I'm having trouble describing what I need. so I'll give you an example. Sorry if it's hard to understand. say I have an array of numbers: (15,5,25,10,20) the percentage of each number can be represented... -
cgi scripts and caching (and also location redirects)
Ok, I wrote a simple script that allows the users to enter a headline and some news, and with the click of a button, post it on the main page of his site. Well, it works great for the most part. There is a preview option, as well as password authentication. When my employer uses the preview... -
sendmail, anyone familiar with it?
What do the arguments: -oi and -oem do? I used to have no problem getting sendmail to work on my server online, but now it no longer does. I finally found a script on the net that works, and it's got those two options on the sendmail program. I'd like to know what they are though... and I... -
strange print() problem. anyone seen this before?
I've got a piece of code that runs through each element in an array doing stuff. It can take a while depending on the size of the array, so I figured I'd be nice and output some percentages to make sure the user knows that something is infact happening... so I stuck this in the loop. ($percent... -
Anyone familiar with Perl and Dos commands?
Is there any way for perl to pick up an in coming messenger message? I wrote a script that will send a "net send" message at a time that I enter, so I can leave and still have the computer send the message at that time. But I want (if possible) to be able to auto-reply if the user I'm... -
infinite loops (sorta) any efficient way to do this?
Essentially, I want a script to run for as long as it takes, when the time is a certain time, I want the script to execute a command. I just did it by going: ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime; while($min < 59 && $hour == 17){... -
why isn't this chomp working?
I have a text file with a name and IP on each line, sepparated by double bars (||) like this for example: userone||22.51.32.32 usertwo||192.32.32.* userthree||32.35.*.* userfour||24.32.62.323 For example. Anyway, when I read in the file, I use the code: my ($users,$ips); while(<USRS>){... -
pattern matching. anything wrong with doing this?
Let's say I have the source code to a webpage contained as a string in a scalar, and all I want to do is print JUST the <body> tag (and everything contained within). I did it like this: $source =~ s/(<body[^>]+>)/$1/; print $1; This works fine - but is there a more appropriate way to do it? It... -
perl pasword encryption, work with PHP
I have a php script that uses the PHP md5() function which "Returns an encrypted hash of it's parameter, using the RSA algorythm." What I'm wondering is, is there any perl modules or anything that will allow me to verify passwords using this encryption system? Just as a test, I tried... -
I despair! no where else to turn. CGI error
I'm trying to edit a perl forum for a friends' company, but before I can do that, I need to get it working on my local server. I'm on winXP running Apache 1.3.27, and the newest version of perl. my CGI scripts work perfectly on my server, when I write them. However, my friend sent me this... -
hashes of hashes
quick question. Say I have a hash of hashes, like this for example: $DB{$membername}{'IP'} = $ipaddress; $DB{$membername}{'ID'} = $membrID; $DB{$membername}{'GRP'} = $membrgroup; My question is simply out of my own curiosity, and doesn't really have any use that I can think of, but let's say... -

one part of a script that I wrote has to output information from a database in a nicely formatted table, that looks different depending on the data that is to be displayed. I have no problem doing this, & it works fine. Here's the problem though. I have a main menu, and when the user selects the... -
