Hi everyone,
I'm trying to implement cookie authentication, but the documentation on
this subject is very sparse!
If anyone knows of some...or some ideas, I would appreciate it.
I'm running Apache 1.3.1/mod_perl on a linux box.
Thanks,

This might not have the correct Perl/TK syntax but what you want
to do is:
Have a panel which contains an image and a callback if it is clicked
upon.
The callback is given the x,y coords of where it was clicked, and
then craft some code which jumps to various subs if it's in a certain
circle, rectangle, polygon, or whatever.
Hope this helps, Leon

Post your perl code and I'm sure the group can do it in less lines in COBOL.
Then give it to your PCS and tell him to take a refresher course.

Message-Id: <35e54a0c.0@news.new-era.net>
Regarding the interpreted nature of Perl: Most non-mainframe
COBOL today is MicroFocus COBOL (there are a few bit players,
but MF dominates the market for COBOL compilers), who have a
multi-platform runtime environment and interpreter. You can
compile your COBOL to native code, or run it under the
interpreter. The interpreter allows for 1) portability (the
same thing the Perl interpreter does), and 2) speed (since
most COBOL code is calling the runtime library anyway -- take
away the runtime services and all you have left is a big
data division and some control structures). So any argument
about interpreted COBOL or Perl needs to be reevaluated
in this light!

If not, try:

Umm In a word _irony_. Custom jobs don't worry about $41 dollars over an

The first place to look would be CPAN, the comprehensive perl archive
network. One way to get to it is by pointing a browser at
http://www.perl.com/CPAN/ and look in modules/00modlist.long.html - in
there you can find
IniConf bdpO Read/Write INI-Style configuration files SHUTTON
and authors/id/SHUTTON/IniConf.pm-0.92.html can be found by selecting the
link under SHUTTON.
So for instant gratification
http://www.perl.com/CPAN/authors/id/SHUTTON/IniConf.pm-0.92.html
might be a place to start.
Hope this helps,
Mike

Well wrote that poster, both of them - both sides of this argument seem
pretty well encapsulated
Maybe this should be posted as self standing doc. I fear the problem
(pathological flamers aside) is that there is no indication of what the NG
expects from it's users except by the abusive postings resulting in the
Nth time a question gets asked, this plus the fact (as we have all
experienced at one point or another) it is easy to misread a hastily
written posting that started out as a good intention. One other small
consideration I'd like to make is that not everybody is using a Un*x
system - so "perl -de" or "perl -f perlguts(3)", might not mean very much
as there is no way of looking up the man pages to find out what that all
means (not being on un*x).

<*>The real problem is exactly the opposite of what you say. Often people seem
<*>to ask the question before even attempting any code. The only way to learn
<*>is by attempt and failure. When I'm not sure about something, I do a "perl

<*>
<*>If you just say "this doesn't work", noone knows what you expected it to do,

Oh. Wait - you forgot one:
- Simon posts his summary twice, just so that we get a chance to
read it again
<g>
But seriously, passwords which give more access than you absolutely
need to shouldn't be in a Perl script. Example: script which accesses
an SQL db should use a user/pass which has read-only access.

No, but does it need to? You can still search for specific text,
which is sufficient 93% of the time.

Subject: Perl script compiling
Message-Id: <1104_904218256@porcupine>
I would appreciate any pointers on compiling a Perl script into C.
My host does not have neither Perl libs nor source installed and I am not sure whether I must have both to use the backend CC compiler.
(Yes, I have read M. Beattie's README but it is like most Perl dox -- the developer talking to himself).
Thanx,
Mee

Subject: SDBM_File on Win32?
Message-Id: <35E56057.A2570F7E@west.net>
Just for yucks, I've been trying to use the SDBM_File module on my
Windows 95 machine (perl ver. 5.004_02, standard distribution). I'm used
to using GDBM files with perl on a Unix machine, so I think I understand
the basics of how it's supposed to work, even if I don't really
understand what's going on under the hood.
But I'm seeing some weirdness with SDBM_File. I located the following
section in the Win32 Perl FAQ:
[FAQ snippet begins]
9.8. Is there a DBM implementation available for Perl for Win32?
Yes, there is. SDBM_File is a free clone of DBM, and is implemented and
distributed with the Perl for
Win32 distribution. You can use it as follows:
use SDBM_File;
# use Fcntl; # doesn't work! see question 9.15
sub O_CREAT { 0x0100 }
sub O_BINARY { 0x8000 }
sub O_RDWR { 0x0002 }
tie( %myhash, "SDBM_File", 'myfile', O_RDWR | O_CREAT | O_BINARY,
0666 )
or die( "Can't tie: $!" );
$myhash{"bibim"} = "bap";
untie( %myhash );
Note that you _must_ use the O_BINARY flag, which is a proprietary flag
defined by Microsoft. DBM
files are "binary", and although this doesn't make a big difference for
UNIX, it matters a lot for Win32.
[FAQ snippet ends]
I can get an SDBM file (well, a pair of files) that seem to hold my
key/value pairs and return them properly, but I'm going through a weird
series of steps to do it.
1) First I try this:
use SDBM_File;
sub O_CREAT { 0x0100 }
sub O_BINARY { 0x8000 }
sub O_RDWR { 0x0002 }
tie( %MYHASH, "SDBM_File", 'myfile', O_CREAT, 0666 )
or die( "Can't tie: $!" );
$MYHASH{"john"} = "successful";
untie( %MYHASH );
This makes it past the die statement, but prints the following error
message:
No write permission to sdbm file at dbm_test.pl line 20.
I *do* create a pair of dbm files, though; they just don't have anything
in them. If I then try this:
use SDBM_File;
sub O_CREAT { 0x0100 }
sub O_BINARY { 0x8000 }
sub O_RDWR { 0x0002 }
tie( %MYHASH, "SDBM_File", 'myfile', O_RDWR, 0666 )
or die( "Can't tie: $!" );
$MYHASH{"john"} = "successful";
untie( %MYHASH );
it works; that is, I can store key/value pairs in the hash, and
subsequent invocations of the script using the above syntax can access
them.
If I try the O_RDWR method first, by the way, before using the O_CREAT
method, I fail at the die statement with a "Can't tie: no such file or
directory" message.
So, my questions are these:
1) Is there some way I can tie the thing initially that will allow me to
both create it *and* do reads and writes?
2) What is the FAQ talking about with the "_must_ use O_BINARY"
statement? I seem to be able to do what I want to do (so far, at least)
without bothering with it. Is that going to come back and bite me later,
or something?
3) In general, what's going on with the three subroutines (O_RDWR,
O_CREAT, O_BINARY) defined in the FAQ example? I don't have to bother
with any definitions like that when using GDBM_File under Unix,
presumably because all that stuff is defined for me in the module, where
I don't have to worry my tiny little brain about it. I don't mind
invoking it as a black magic, but I get the sense it's involved in my
confusion over the other issues, so I'd appreciate it if someone could
explain to me a bit more about what's going on.
Bonus points if you can do so using small words that even a
non-programmer can understand.
Grateful in advance for any enlightenment...

Message-Id: <35E553B9.FB844EEA@mindspring.com>
HELP!
$tmp = `grep bob file.txt`;
if ($debug) { print "$tmp<BR>\n"; }
@tl = split("\n",$tmp);
used to work fine, but for some reason the $tmp line is
now only seeing one line of the multiple lines returned from
the grep command. This used to work fine (months ago),
and I'm not sure what's changed on my ISP's system. A
new perl or new OS version may have been loaded. I
checked, and I'm using perl 5.003 on a Linux machine.
As a note, this also doesn't work on an IRIX machine
(Silicon Graphics UNIX OS).
I would do this grep function in perl, but file.txt is about
3M and the perl routine seems to be much slower.
Any ideas you have would be appreciated!

Different logins but the same directory? That's so dumb it hurts.

What's dumb about that? If they have the same uid, Unix doesn't care
what the usernames are. Then you can give one username and one
password to one person, another username and password to another
person, but they can still share the same resources.

Marc I think you'll find advice will be thin on the ground or similarly
informative as Dan's posting - You might get the info your looking for by
asking in the following news groups or at least some pointers:
comp.infosystems.www.authoring.cgi,comp.infosystems.www.authoring.html,comp.infosystems.www.authoring.site-design,comp.infosystems.www.authoring.tools,

To request back copies (available for a week or so), send your request
