The important code with problem is:

#This line is not printed because the OS is Linux but the following line has
problems
use Net::SMTP;
...
How can I avoid Linux complaining that there is no Net::SMTP module installed even
though I've
tested not to be necessary?
The problem is that a use Net::SMTP; statetement is evaluated at compile time.
That means even if you write something like
if (0) {
use foo;
}
The compiler will try to load foo;
You can avoid it with using require:
if ($^O =~ /MSWin/i) {
...
require 'Net::SMTP';
Net::SMTP::import();
}
Require is evaluated at run time.
Note that the import call is necassary.

PS: BTW, it's better when the subject gives a short description of the problem.

Then I've seen one more error in that file:

That line is:
for ($i = $line + 1; $i = $max $dbline[$i] == 0; ++$i) { #{ vi
Is there any bug, or what could be the problem?
I am using Windows 2000.
If I run the script normally, the script runs without errors or warnings.
Did you run the script with
use strict;
use warnings;
?
(what should be normally)
I believe (allthough I'm not sure), that debugging switches warnings on.
When $dbline[$i] contains a \n then the warning is definitly good.
Perl warns you, because

Re: What database would your recommend?
MySQL is a relational database. Taken from the mysql documentation page at http://www.mysql.org/documentation/mysql/bychapter/manual_Introduction.html#Features MySQL is a relational database management system. A relational database stores data in separate tables rather than putting all the data in one big storeroom. This adds speed and flexibility. The tables are linked by defined relations making it possible to combine data from several tables on request. The SQL part of ``MySQL'' stands for ``Structured Query Language''@-the most common standardised language used to access databases.

Re: How to blank out a form?
I think what happends is that even though you place the blank field there, the text is still really there, try using the print command on the same page and take a look to see if it actually does erase the data or does it just erase it in the form text area, I had the same problem, I just let people delete the old text Walt Sanders [EMAIL PROTECTED] 06/06/02 12:50AM This one is a little hard to explain. I have a .cgi program that offers a textarea form box. The contents are used to generate a text file that is then used as an SSI in an html program. This text must be changed from time to time. In order to make it easier to modify the text, I grab the previous text and put it into the form for editing. Problem is: if one wants to blank out the text entirely by deleting everything and submitting it, to have nothing placed in the text tile, the entire previous message reappears. The blank form doesn't take. Work around has been to place at least one blank space in the form. Then everything works fine; I get a blank text field file. Rather than having to explain to all other users to do this, it would be much better if one could just delete the text (blank out the form) and submit, rather than having to remember to put a space in. I don't know how to make this happen. Here is the snippet: my $textold; open(EVENT, event2.txt) or die(Cannot open: $!); $textold=EVENT; close(EVENT) or die(Cannot close event2.txt: $!); print FORMSTART; form method = post action = eventput2.cgi pstrongEvent Title: /strong input name = title type = text size = 40/p strongEnter Event Description amp; Details Here:/strongbr textarea name = comment rows = 20 cols = 72$textold/textarea/p . $textold is forwarded even when the blank is submitted empty.

Oh, I'm afraid that's not the truth :-)
subroutine without any arguments calls the subroutine with the

while subroutine only calls subroutine() without any argument.
Look at this snippet:
@_ = qw(A B C);
print 'foo:'; foo; print \n;
print 'foo:'; foo; print \n;
sub foo {

It prints:

Re: What database would your recommend?
Hi all, Having spoken to consultants/teachers that I know, their experience matches my own. When teaching, they prefer PHP. When programming they prefer Perl. It's basically horses for courses. I use PHP for what it's always been designed for which is creating dynamic web content. For application development (batch, console, complex CGI etc) I use Perl. The big advantage here is that wil PostgreSQL being the back end I can easily combine both languages in a project as appropriate.

RE: What database would your recommend?
well.. I have 6 years Perl.. but I don't do web design, and no PHP programmer has been me out of a position yet. I am not shooting down PHP, but Perl has many many advantages over PHP, but PHP is better for DB access via a web front. But Perl is better at backend access and overall reporting (not DB reports alone). It's just not a dead or dying language. I think with Perl 6 it will have much renewed vigour.

Not to be pedantic, but isn't PHP a *language*, not a database? So you could use almost any particular database with either PHP or Perl. Or does PHP have it's own built-in database and that's what you meant? (I looked at PHP a little once, and I have to admit a knee-jerk negative reaction to a language that relies on indentation for intuiting program flow.

RE: webBotting a Job Hunt
Depends... there are those that don't know Perl, so I see nothing wrong with it unless you are using this for profitable purposes. Remember, if it's free, how is it wrong? If you think it's wrong that it is free, then help them make it less free. Linus idea, followed by Gates idea. I think this is a question which you can only answer for yourself. I am planning to make a web browser to end all browsers, but that's not for a few years. The idea is the browser will be configurable to block ads (in the page) and popups, with just a few user clicks. So my ethical problem is, is it right for me to make this? You can't stop the end user form changing the viewing style. Some browsers that do that do it without the users intervention.

I already do half of that by using lynx instead of netscape (heaven forbid ie :-) so that I don't bother with images and am not subject to JS code and so on. In the past I've said that it's pretty easy to have the site's search agent go through the postings for you and then read the email that comes in, particularly compared to writing a script that will go and get the info for you, but it might not be easier for some :-) That's even closer to your stated goal; the mail I get from dice doesn't have any ads in it (er, well, I don't think so; if it does, I now skip over them by searching for the beginning-of-job marker and don't notice anyway :-) and yet they're happy to send it to me. Hacking your way around a .htaccess file, as an example, would probably be another story, but I don't think that's within this scope. 2) i want a copy :-) % % % ciao % drieux HTH HAND :-D -- David T-G * It's easier to fight for one's principles (play) [EMAIL PROTECTED] * than to live up to them. -- fortune cookie (work) [EMAIL PROTECTED] http://www.justpickone.org/davidtg/Shpx gur Pbzzhavpngvbaf Qrprapl Npg! msg05262/pgp0.pgp Description: PGP signature

Re: What database would your recommend?
Relational databasing just means that there are keys associated between the different databases that allows the database software to easily make matches from one database table to another very quickly and efficiently. I don't know if you've ever heard the term primary key before, but it simply refers to a unique identifier that is common to the database tables and uniquely identifies one and only one object in each of the databases. I believe that's what makes up a relational database. As for transactions, only very high-end commercial databases (such as your friend's Oracle) support transactions. They are only required in applications such as real-time transactions. For example...Etrade.com would use Oracle probably to control all trading, and amazon.com would use Oracle to control all inventory and purchases. I hope this answers some of your questions.

Refresh dynamic content using query_string
I was wondering if there was any way to refresh and have the same
dynamically-created page viewed every 5 seconds?
I'm trying to do it like this:
my $URL2 = ds0.cgi?$ENV{QUERY_STRING};
### HTML part
print $q-header( -Refresh='5; URL=$URL2' ),
But this doesn't work. The URL that is recreated is literally
interpreted as:
/cgi-bin/ds0.cgi?$URL2
And thus can't be found (script not found or unable to stat).
If the user was at:
/cgi-bin/ds0.cgi?rgrp=NOVA+MEX
I need for the bit of code above to re-create that string so they are
refreshed to it after 5 seconds.
What am I missing here?
Any help much appreciated.

Have you tried printing your header with instead of ''? I believe ''

David,
You are the man. That worked. Just when I was figuring out that this
was a variable interpolation problem.
I could use $URL4 instead of $URL2, and it still wasn't interepreted
as a variable, and $URL4 wouldn't be declared anywhere in the
program.

Using strict and a configuration file?
Hi all, Is it possible to use use strict; if I get the variables from a configuration file? I've tried: use strict; require f:/xxx/config.txt; #In the configuration file I have a line like my $test = test test test; print Content-type: text/html\n\n; print $test; This gives me an error that I should define the variable $test. I don't want to define it in the script but in the configuration file. However, if I define it in the script with my $test; the script prints an empty string and doesn't take the variable from the configuration file. Is it possible to use strict, or it is necessary to use no strict;? Another problem, maybe bigger is that even though the script is running fine, it give me errors in the log file telling me that the variable $xxx and $yyy, ... is used only once. Is there a good method to define variables for more scripts in a single configuration file? I don't want to store my email address and other settings in each script because I may change that address, and then I will need to modify a lot.

Sorting a hash by values?
Hi all,
I want to make a script that sorts the values from a hash.
I want to make a top with the most downloaded files.
I know how to sort the hash by keys but I couldn't sort it by values.
I have a hash like:
%hash = (
file1 = 3,
file2 = 11,
file3 = 6,
fileN = 22
);
I would like to print the name and the number of the downloads in descending
order like:
filename number x: 33
file number y: 6
...
file number z: 2
Is there a function that sorts by values?
I've tried (but with no results:
foreach $cnt(sort values(%hash)) {
print $hash{$cnt}: $cntbr;
}
Thank you for any tips.
