Could the missing 'x' really be a signal? Compound that with the OP's ID

Simplest way I can think of is $string =~ s/(.{7})/$1\n/g;
Unless of course, you need the string later, or really want an array,
etc.

Subject: Accessing config files from CGI scripts.
Message-Id: <3950357F.F030809C@esec.com.au>
Does anybody have a neat way of accessing config files from a
Perl/CGI script ( running on Linux/Apache)
I need to read the configuration file to access data that I don't want
to hard code into my script. For example, the username for accessing an
oracle database, and I also don't want to hard code the location of the
configuration file in my script. I realise that environment variables
are an option but setting them in a the web server config file would
mean that they apply to all CGI scripts run from that particular web
server.
thanks in advance for any suggestions

This sounds like you want to make a CGI program to provide access for your
database. If the database isn't on the same machine, your program will
need to access it over the net, or whatever. If you have questions about
CGI programming, you may want to search for the docs, FAQs, and newsgroups
about CGI programming; reading comp.infosystems.www.authoring.cgi may help
you to get started. Cheers!

Probably you could make a port driver which squirrels a copy of the data
to somewhere where your Perl module can peek at it. But if you've never
written something so low-level as that, it may be pretty tough. Good luck
with it!

Subject: Converting GUID into hexadecimal format

Hi All,
I am trying to convert a regular GUID format to hexa-decimal format
and are wondering if you have a simpler method than what I currently
have. If this is the appropriate method...
(Q) Do you know how to store the id generated into an array and be printed
out instead of storing into a physical file. So far, when I attempt to store
the id into an array,
I get the following result - ARRAY(0x8b92214) instead of the hexa-decimal
id, when I open the
ARRAY(0x8b92214) file, I am able to see the hexadecimal id generated in the
file but not print.
Regular guid format :
{DA86E130-470E-11D4-9F14-0080ADC93510}
Hexa-decimal format:
0xDA86E130, 0x470E, 0x11D4, 0x9F, 0x14, 0x00, 0x80, 0xAD, 0xC9, 0x35, 0x10
Please let me know if you need more explicit information.
Any advise would be appreciated. Thanks.

(-A $filename) returns the time (in days) since the file with name
$filename was last accessed.
-M and -C do similar things. Details are in perlfunc.

Does the Perl/Tk widget demo work under Perl 5.6 on Windows? If the
command 'widget' starts that up, you'd be on your way. Hope this helps!

Windows directory is easy. Try using the $ENV{'WINDIR'} construct. As
far as I know, it works on all Win32 variants (tested on 95, 98 and
NT4).
As for Program Files...well, good luck. There's no consistent key in
%ENV for that. Maybe someone else will have a better idea, but the best
I can come up with would be to search the registry for something that
you know would be installed there (IE comes to mind) and look for a Reg
value with a directory specified.
Hope this helps,
JH

From my VB days, I can tell you that there is a windows API call that
returns the windows directory. What it is I have no idea any more, but
you should find it if you consult the appropriate documentation. It is
likely that something similar exists to find the progam files dir too.
I would imagine there would be a perl module for using the windows API
on CPAN somewhere.
Good luck,

Are you sure? HTML is difficult for humans to input, and it's not much
better for output. If you want a GUI, I'd much prefer Perl/Tk.

I find him less than rude, too. :-) But I find your implication (that he
would be rude rather than helpful) to be troublesome. Perhaps you will
consider all of us rude, no matter how helpful we are. Maybe no one should
answer you. Please try to see everyone's replies in the best possible

If your webserver supports CGI programs, you should read its documentation
to see how to do that. But what's this about CGI programming? You were
talking about something else before, weren't you? Still, if you have
questions about CGI programming, you probably want to search for the docs,
FAQs, and newsgroups about CGI programming, including reading
comp.infosystems.www.authoring.cgi.
Good luck, with whatever you're doing!

Synch up your clocks and try it again. Looks like you have a file server
with a date that's out of synch with your local machine. make doesn't
like this.
Also, if you want the tests to all complete successfully, you'll need to
give it a valid pop3 config to work with. Look at the README
(POPTESTACCOUNT) or at line 32 of t/poptest.pl.

One of the best ways is to read the FAQ first:
"How can I extract just the unique elements of an array?".
The answer may be found on your local disk by typing
'perldoc perlfaq4' or at

It's not, because there's no such thing. Oh, well!
We may be able to tell you that a given program has a security problem,
but no one can reliably say that it doesn't. Even if the program itself
were perfect, it may be installed in a way which opens a security hole on
your system.

Well, I just took a look at the htgrep FAQ page.
http://iamwww.unibe.ch/~scg/Src/Doc/htgrep.html
It looks as if this hasn't been updated in some time, which worries me. It
doesn't use modules, which worries me more. And it uses eval on a string
generated from user input, which worries me most of all. Perhaps if I
spent some time studying the program in more detail, my worries might be
relieved, but perhaps I'd discover a serious security hole.
As it is, I can't recommend this program. If it were rewritten to use
standard modules for processing the CGI params, parsing the HTML tags, and
whatnot, that would help. If it used Perl's taint checks, that would be
even better. I have to give its author credit - clearly the program was
written with some thought to security. Still, unless someone who
understands the security issues goes over it carefully, I can't recommend
that you use it.
If you'd like to hire someone to vet the program, let me know by private
e-mail and I'll send you some recommendations.
Cheers!

Does the update still give write access to the files in the directories?

I'm not the original griper, but you're missing the point.
If I'm a Perl programmer who uses Linux, and I want to use your Perl
IDE on Linux, I have to install and configure some completely unrelated
bit of software to do it.
We expect installers and perhaps IDEs to require a shell, the usual
set of scripting tools, and maybe even perl itself. But Linux users
(nor most Unix users) would not assume that having and using Wine is
a normal prerequisite to using a Perl IDE.
Tail wagging dog. Cart before horse. That kind of thing.
And Wine itself is so doggone big and complicated that you've just
about eliminated the possibility that someone might download and
try the demo on a lark.

Hi,
I want to upgrate the perl5.002 to the perl 5.002_03 version. Just
wonder currently my working environment is running some update scripts
that pointing to the old perl version. If i directly upgrate the perl,
is that any impact or whether it will affects the scripts running or
not? Because the update scripts are quite critical. So, i dont wnat to
take risk. So, is there anybody can help?

Use an existing one rather than making your own. But this isn't really a
Perl programming question, is it? The program could be written in nearly
any capable programming language. There aren't any Perl-specific issues
here, are there? It sounds like a question on programming for the web,
which is generally better discussed in comp.infosystems.www.authoring.cgi.
In any case, many folks like minivend.

Well, file locking problems are easy to solve. Still, cookies aren't
supported everywhere, and they identify browsers, rather than customers.
So they're generally not a good choice.

Well, that's one way to do it. If I were starting from scratch, I'd
probably use authentication, myself, since I don't see the need to give
the users a choice there. But if you have questions on authentication, the
folks in c.i.w.a.c know all about it. Cheers!

We have designed a frame shopping cart,
and a window shopping cart.
if interested, please visit
http//www.gboworld.com/index.html
It is easy to use and design.
One of our customers has a site
http://intercomp.com.au/e-bellingen
You may like to visit it also.
Our shopping cart should be in a different
type which is not listed in your list.

Message-Id: <39503c8e@news02.imsbiz.com>
Hi,
I would like to ask about what is "expires" use for in the cookie?
After the cookie expired, will the cookie removed from the client
automatically?
Or the expires date is just use for the server to know is the cookie expire
or not? I mean the cookie is still in the client computer, and the server
just read the expire date from the client. Then check does it expired, if
so, then quit the program somethings like this?
Also, the expire date is base on client's computer time or server time?

No. Your original question has received a better answer than you seem

You probably didn't see the smile on Tad's face when he said that. He was
trying to make you chuckle. Try to give him the benefit of the doubt, and

This comes up every month. :-P Not your fault; I don't see it directly
addressed in the FAQs. Or the Perl Cookbook, either.

Yes; that does the work in a subprocess; it doesn't change the values in
your Perl process.
One way to do it is to have your subprocess tell you what the values
turned out to be, then parse that to set up whatever you want.
my @shell_vars = `. bashscript.sh; set`; # or whatever
Parsing the return value shouldn't be too hard, but remember to deal
properly with quoting and line continuation characters. It may be better
not to modify your own %ENV, too; there's no need, and it could
potentially be harmful to your PATH.
An alternative is to parse the file directly in Perl. But what can you do
about lines which use shell built-in functions, or which call external
programs? Pretty soon, you're re-writing the shell in Perl.
Good luck with it!
