HTML::Parser, from CPAN. Consult the module list on CPAN if you need to

Yeah, I dove into that for a bit, but it didn't, at first blush, appear to
do what I wanted. It might facilitate it, but it struck me as a little
heavy handed. I've found it really convenient to simply specify a file name
and a hash, and have a function spit back the HTML will all the fields
filled in. I have a fairly comprehensive pile of modules, and I was also
searching on CPAN.
I'll look at HTML::Parser again

I have downloaded the NT counter from Behold Software, I then found out that
they also have a statistics program called WWWSS (WWW Server Statistics) ,
which I think is freeware.
I have tried to access there site for about 3 weeks and it doesn't work.
Please can anyone send me a zipped copy of the program so I can use it. I
am not asking you to do this illegally, because it is freeware.
Please Help!

From the CPAN (Comprehensive Perl Archive Network). Go to
<http://www.cpan.org/> to find your nearest CPAN site. CPAN is a Perl
developer's best friend... learn all about it.
The CGI module will be able to handle the mechanics of your file uploading.
Also available from CPAN, if needed.

FrontPage, alas, does not output HTML, but garbage. Just use your
favorite text editor (be it Emacs, vi, HomeSite, CodeWright, NotePad
or whatever) for everything and write tools in Perl to upload the
files to where you want.
Do you understand the difference between CGI (all caps) and Perl
(capital P)? CGI is an interface that web servers provide. The server
might be configured to execute a Perl program when it sees a URL
ending in .pl that does something useful (hopefully) and returns the
result to the server, which returns it to the browser. Perl is one of
the languages you can write CGI scripts in, but not the only one. You
can also have shell scripts, VBScript (on Windows anyway) or anything
else that can read environment variables and print text.
But Perl is an elegant language, from the more civilized days. Not as
random or clumsy as VBScript.

Message-Id: <37BC4DFE.A89D6863@chollian.net>
I tried to compile my perl scripts with perlcc.
A simple script was compiled well. But when I compiled the scripts that
contains perl modules and my library files, there were several errors!!!
I have tested on two systems, one was the system that has perl compiled
with static way, and the other was the machine with perl compiled that
supports dynamic loading support. Both failed.
I don't know how to compile... pls help me.
my script starts like the following:
#!/usr/bin/perl
use CGI;
use DBI;
require "mylib.lib";
require "myconfig.conf";
..........
......
and there were two cases:
[CASE 1]
root>perlcc info_admin.pl
........
.........
it compiled successfully, but when I executed the compiled binary, an
error occurred!!!
error message was like this:Can't load module IO, dynamic loading not
available in this perl.
(You may need to build a new perl executable which either supports
dynamic loading or has the IO module statically linked into it.)

Use the open() function/sub to do this.
open FILEHANDLE, ">/path/to/file" or
die "Could not open file for writing";
Don't forget to close it when you're done.
close FILEHANDLE;
Good luck. Check out the 'perldoc' command. Do a 'perldoc -f open' for more
reference on the open() function.

Well from the command line
perldoc -f open
displays the documentation of the open function, the second paragraph
deals with what you want.

h2xs is mainly used to create extensions. You can use it to create
modules (classes), but only if you want your real code to be in C,
with a Perl wrapper that calls the appropriate compiled C
functions. See perlxstut for more details.
I don't use it to create my modules, which are pure Perl. You can
learn more about modules in Perl by reading perlmod, perlmodlib,
perltoot, perlobj and perlbots.
> If I should type the classes in normal files myself and h2xs is not
> necessary, what should be the file extension?
.pm ... The name of your package (class) should be the same as the
name of your file (without the extension). For example, if you want to
create a package called Animal, you would create a file called
Animal.pm. One of the first lines in that file (usually) would be:
package Animal;
To create an object of this class, you need first to 'use Animal;' in
your script. Make sure that Animal.pm resides somewhere where Perl can
find it.
> How do I distribute various classes in diff. files? can I include

You can do both. Read more on Perl's modules in the perldocs I
mentioned above.
Another good source of info (docs and real-life examples) would be the
Ram (the Perl CookBook), written by Christiansen and Torkington,
published by O'Reilly.

In the Ram, there are several recipes to manipulate CSV's.

There is plenty of documentation already. Check out Ram:12 (that is
tchrist's new notation meaning chapter 12 of the Ram), entitled
"Packages, Libraries, and Modules", as well as Ram:13 "Classes, Object,
and Ties."
There are also chapters 6, 7 and 8 of the Panther.
Docs are plenty.

! h2xs is mainly used to create extensions. You can use it to create
! modules (classes), but only if you want your real code to be in C,
! with a Perl wrapper that calls the appropriate compiled C
! functions. See perlxstut for more details.
h2xs is not just for creating C extenstions---it can also be used as
a simple method of creating a skeleton module along with extra files
for making a standard distribution package.
$ h2xs -Xn Foo
Writing Foo/Foo.pm
Writing Foo/Makefile.PL
Writing Foo/test.pl
Writing Foo/Changes
Writing Foo/MANIFEST
Now all you need do is fill in Foo.pm, add some tests if appropriate
and possibly edit Makefile.PL if you want something beyond a generic
installation. see man h2xs for more details.

There is a Perl module DBI.pm which abstracts access to many database
backends into a single interface. Once you have DBI.pm (available from any
CPAN site <http://www.cpan.org/>), then you need to get the DBD (DBI
Driver) file for the database backend you're using (in this case, MySQL).
Once you have both installed, you'll do something like this:
use DBI;
$dbh = DBI->connect("dbi:mysql:dbname") or
die "Could not connect to the database!";
$sth = $dbh->prepare("select * from table_one");
$rv = $sth->execute;
if($rv) {
for(1..$rv) {
$row= $sth->fetchrow_hashref;
print
"Name: $row->{name}\n",
"Address: $row->{address}\n";
}
}
$dbh->disconnect;
See the DBI manpage (type 'perldoc DBI') for a complete set of information
on how to use DBI functions like prepare(), do() and execute().

Maybe you're not waiting long enough. It semlls like buffering to me. See

Subject: perl-DBI problem
Message-Id: <7phgcu$7p3$1@nnrp1.deja.com>
Perhaps the wrong forum for this however, I am at my wits end.
When trying to load DBI.so from a script I get the following message:
----
Can't load '/usr/lib/perl5/5.00503/i386-linux/auto/DBI/DBI.so' for
module DBI: /usr/lib/perl5/5.00503/i386-linux/auto/DBI/DBI.so: undefined
symbol: dirty at /usr/lib/perl5/5.00503/i386-linux/DynaLoader.pm line
169.
at ./list.pl line 3
BEGIN failed--compilation aborted at ./list.pl line 3.
----
I previously had DBI up and running on a RH5.2 using
perl-5_004m4-1_i386.rpm.
RH 6.0 ships with perl-5_00503-4_i386.rpm. The default directory under
perl-5_004... was /usr/lib/perl5/site_perl (this is where DBI loads)
the default directory for perl-5_00503... is /usr/lib/perl5/5.00503/
@INC does not contain /usr/lib/perl5/site_perl so I copied all related
files from site_perl to 5.00503 directory and not get the above error
message. Can anyone help figure this out. I have looked high and low
across deja news and find very few messages regarding this.
Anyone else having this problem. I have heard that switching back to
the old perl (5_004m4-1_i386.rpm) was a fix, however I have other things
relying on the new version of perl that ships with RH6.0
Bahhhhh!

Personally, I'd just grab the DBI module package from a closeby CPAN site
and re-make it and install it.
