Hi all
complete beginner, please excuse my lack of know how.
i've been trying to install apache/activestate perl
to start learning about cgi from the file at :
http://www.egovision.com/htmlresources/articles/apache_win32.html
however i can't seem to get the thing to work !
ive followed it word for word and can execute the perl interpreter
successfully with a script from the prompt
(i.e perl C:\apache\cgi-bin\test.pl)
, but can't seem to print it out to a html page. everytime i do try
it runs a window and flashes by me in a window ?!?!
my html to execute the script is :
+++++++++++++++++++++++++++++++++++
<html>
<a href=test.pl>go tester</A>
</html>
+++++++++++++++++++++++++++++++++++
and the actual script is
+++++++++++++++++++++++++++++++++++
#!C:/apache/usr/bin/perl.exe
$time=localtime(time);
print "Content-type: text/html\n\n";
print<<'end_of_block';
<HTML><HEAD><TITLE>My First CGI Program</TITLE></HEAD>
<BODY BGCOLOR="#FFFFFF">
<CENTER><H1>My First CGI Program</H1><CENTER>
<P>
Your host is: $ENV{'REMOTE_HOST'};
<BR>
The time is: $time
<P>
This is the end of the program. Like I said, not very useful
but we will be getting to the useful programs soon!
</BODY></HTML>
end_of_block
+++++++++++++++++++++++++++++++++++
what am i doing wrong ?
am i completely missing something vitally important ?
in the above file i mentioned i couldn't get the "perl" to appear
in the top name bar. is this of significance ?
also while im on the subject can anyone recommend any more good
beginners tutorial's ? ive searched the engines but personal
recommendations gladly appreciated.

Subject: Help Needed - Perl & SQL
Message-Id: <yjKs3.1092$Sg.64009@typhoon-sf.snfc21.pbi.net>
I am looking for someone who understands both PERL , SQL, and SQL Server 6.5
really well to give me a call. I am having problems displaying text pages
as the SQL wants to cut the data off at 256 bytes or characters of data.
Microsoft says that you can display up to 2 gigs of data. I want to display
pages of information up to 20,000 bytes or characters of maximum. I am
looking for a script to help me display all of the text I need for the
people that will be using my website.
I look forward to your reply.
Thanks, and have a nice day.

I *do* answer questions that are in the documentation, but hard to find.

Your one involves copying the entire array to a hash, which is also slow.
If speed is critical, you are better off using a hash in the first place.

Yes, but what is the best depends.
For a small number of queries, use grep. (How could you miss that?)
For larger number of queries, you want to preprocess your data, as
the FAQ will explain to you.

I know this isn't directly related, but I'm getting mildly desperate.
I've been trying for two weeks to get a shopping cart system installed and
running and am having no luck. My hope is to find an expert to get things
working and show me enough that I can take it from there.
The program I'm trying to get configured and installed is Perlshop.cgi,
available as shareware, but having more of the features I need than most of
the commercial products I've investigated.
The server I'm trying to run this on is an NT Server running IIS 4.0 with
ActivePerl.
I'm located in Campbell, CA and have documentation on how to set up Perlshop,
which I have read and re-read diligently, but I haven't had any success. If
you are willing to help, please contact me at BigDoggy@MakersMall.com.
FWIW - I'd really like to have the shopping cart up and running by 8/15.
Thanks

Well, you may have heard of the -i flag, but do you know what it does?
I would use either:
% perl -pi -e 's/\cM//g' oldscript.pl
or
% perl -p -e 's/\cM//g' oldscript.pl > fixedscript.pl
And I would use a shell where the default prompt is `$', but that's

Why is this posted in the thread "Newbie seeking for advice"? You don't
followup to any of the postings in the thread, nor do you contribute
even in the slightest way. Yet, you copy the References line.
That's very poor netiquette. If you don't know what the buttons do,
don't press them!
While I know the answer to your question, I won't answer them.

You need to be authenticated to send (relay) mail thru the server in
question..
What Nat & Tom do state, on pg 653, is that WinBlows doesn't normally
support sending mail from itself, so you have to find a server that is
-
1) Configured wrong by the mail admin and allows relaying, or
2) Buy a real mail server platform - IE, Unix :) OR
3) Get your upstream provider to allow you to spam the free world...

Okay, I downloaded ActivePerl, and installed it. Smooth as silk.
But...
I wrote the ubiquitous "Hello World!" program (oh yes, I'm on my way...). I
have .PL files associated with Windows Explorer, so when I click on the
icon (what is it -- a lemon? I can't tell), a window pops up and I just get
a glimpse of "Hello World!" before it disappears.
I've tried to run programs from the DOS prompt, but no luck.
How do I get the "execute" window to stay up so I can view the results of my
program? Is this a Perl thing, or a Windows thing?

Deane Barker explains it all:
:I wrote the ubiquitous "Hello World!" program (oh yes, I'm on my way...). I
:have .PL files associated with Windows Explorer, so when I click on the
:icon (what is it -- a lemon? I can't tell), a window pops up and I just get
:a glimpse of "Hello World!" before it disappears.
Performs as advertised!
:I've tried to run programs from the DOS prompt, but no luck.
What did you try? What happened?
Stick with running them in the DOS window:
perl -w hello.pl
That should work.
Be sure to read the "Quirks" section of the FAQ that came with the
installation, so you'll be ready when this doesn't work:
perl -we 'print "Hello, World\n"'
Read all the other FAQ sections too, there's a wealth of valuable
information in there.

It always makes my brain hurt when thinking about "text files" and
"binary files". It's not that my OS cares. Files are just a bunch
of bytes in a given order. Be it in working memory, on a disk, a
tape, or waiting at the other end of a pipe or socket.
You just have file were it sometimes makes sense to process them up to
(and including) a certain byte sequence one at a time, and files where
it doesn't make sense to do so.
"Text files" and "binary files" are just mumble-jumble definitions.
Not very useful, and not very well defined.
Now, there might be OSses that do care about "text files" and "binary files",
but those are just plain silly. In real OSses, files are either a sequence
of bytes, or a sequence of records.

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq" from
almanac@ruby.oce.orst.edu. The real FAQ, as it appeared last in the
newsgroup, can be retrieved with the request "send perl-users FAQ" from
almanac@ruby.oce.orst.edu. Due to their sizes, neither the Meta-FAQ nor
the FAQ are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq" from
almanac@ruby.oce.orst.edu.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
