If you are going to write to Alot, it would probably be better to send
him/her an email, rather than post these obviously private conversations
in a public newsgroup.
BTW, yes, this is weird. Where are these "hidden fields"? In Iowa?

Hi,
appologies for posting this twice, I seem to be having problems posting.
I am trying to write a script which does the following.
Web browser activates cgi-script.
Script makes pipe
script sends to stdout a "location" which points to the pipe
Web browser connects to the pipe
script opens binary file
script streams binary info to pipe.
web browser displays file (pdf)
The reason I am using pipes is so I can name the pipe, the name of the binary
file so that the pdf file has the correct file name.
Why dont I just point the browser at the pdf file?
Because the files are outside the web root, for 2 reasons.
1. security
2. dont get indexed.
OK.
The only thing is, I dont know how to use pipes on NT.
I have used them on UNIX but that was a case of mknod and system calls etc.
So my real question is:
Does anyone have any examples of named pipes for NT?
Or can you think of another way of doing what I am trying to do?
Cheers,
Matt

Whenever you have to do something in Perl, you have a
50% chance it has been already done in a module

Hello,
Maybe I am missing something here, but I am trying to do something
which should be simple but I can't figure out how to make it work.
I need to open a file with a global filehandle that is visible for
all the modules of my program. Just declaring it in main gives the
error
'Filehandle Netmap::STDLOG never opened at Netmap.pm line 144 (#1)
or something similar for each write attempt.
There must be a way to do this, but what is it?

a. the last statement of html.pl should return true. I usually
accomplish this effect by ending my modules and required files with
1;
# yes, just one and a semicolon
b. read CGI.pm documentation. You seem to be re-inventing
the wheel.

All of the messages that perl might issue are documented
in the perldiag.pod standard perl doc that is installed
on your hard disk somewhere.
For your message it says:
-------------------
=item %s did not return a true value
(F) A required (or used) file must return a true value to indicate that
it compiled correctly and ran its initialization code correctly. It's
traditional to end such a file with a "1;", though any true value would
do. See L<perlfunc/require>.

Hi,
I've written a script, using module Text:ANSIColor to display

All is right but when i pipe to a print queue, i get control caracters.
So i would like to display via STDERR in color, and if specific
SDTOUT is used (means if a pipe is defined) then prints without color
functions.
So, how can we know if STDOUT is redirect ?
Thanks in advance for your help

But that's actually why I pointed it out. Checking $1 without having
checked whether the match succeeded leads to general errors akin to
opening a file without checking the return of the open. Sure, you can
write legal code that doesn't check that stuff, but more likely than
not, you'll be debugging *forever* in some other part of your code
without realizing where the true source of the error is.
And having an answerer provide bad bits of code is something I'm
always on the watch for. We don't need to hand bad bits to newcomers.
Yes, the experts know exactly when we can get away with it, but we're
talking to non-experts here. It's like handing someone a lightsaber
when they ask for a cutting tool, but not really telling them that
it'll pretty much cut through *everything*, or how long the blade
is. :)

Thanks for all the info: How about this (w/ great thanks to larry

my $string = "123ABC456ABD"
my ($substr1, $substr2);
($substr1, $substring2) = $string =~ /(^\d+)\D+(\d+)\D+/;
# so $substr1 = 123 and $substr2 = 456
Now would it be better to do this?:
if ( ($substr1, $substring2) = $string =~ /(^\d+)\D+(\d+)\D+/ ) {
print "yay!";
} else {
print "too bad";
$substr1 = $substr2 = "";

I'm afraid that Randall, Tad, yourself, and I are all going to have to
agree to disagree on this particular topic. We shouldn't be answering
questions that weren't asked, and the example was written to show
specific uses. I'll stand by that every time.

ObTrivia: I believe 'cl' stands for '_C_ompiler and _L_inker driver',
since cl.exe invokes other programs with funny names such as c1xx.exe
and link.exe etc. which do the actual dirty work.
Borland calls their C compiler tcc or bcc. FWIW.

You are AIUI. Though, for example, the Xitami web server apparently
interprets shebang lines and tries to start the program specified there,
in which case it would have to be c:\perl\bin\perl.exe or some such. But
the OS couldn't care less about the first line -- it just looks for .bat
.com .exe in its standard path.

You can use one of the MS-DOS ports from
CPAN (you don't say, but I suspect that is
your OS). Expect limited module support -
but CORE functions should work. There
are a number of ports - you'll need to check
the READMEs to see what is/isn't included
in each one.

If youve a
<select name=wibble multiple>
<option>a
<option>b
<option>c
it comes in as
wibble=a&wibble=b&wibble=c etc
if youre using CGI you can read it into an array:
use CGI;
$q = CGI->new;
my @wibbles = $q->param('wibble');

I'm running an indexing script called webcrawl from Brian Slesinsky
(http://www.webmonkey.com/code/97/16/index2a.html) that I adapted for
Win95 to index my site. It uses the dbmopen function to tie the index
to a hash. After 10 minutes of work it terminates with the message:
sdbm store returned -1, errno 22, key "in" at webcrawl line 104.
It makes these files:
SEARCH~1 DIR 4 096 99-04-30 15.41 search_index.dir
SEARCH~1 PAG 23 664 640 99-04-30 15.41 search_index.pag
I suspect a size problem. Is there a limitation in the size of hashes
or sdbm files?

Yes to both questions. You need a better DBM. Dave Roth has
ported GDBM to NT. I don't know if his port works on Win95 -
but that is one place to look.

* * ? * * are there DIFFERENT syntax rules for:
a: <input type=\"hidden"> or

besides the obvious that textfield gets displayed and typed into before
submission, and the hiddenfield just gets generated value=\"$thevalue\">

then how do you explain the customer input script - a cgi generated page
that had a VISIBLE text formfield in it? the customer simply typed in
I am 5'10" tall
clicked the submit button, and WOILA! the action launched another script which
simply parsed the incoming values properly, opened a dBm file and entered the
value PERFECTLY? if you VIEW that dbm file you will see very literally:
I am 5'10" tall
if this same script also prints it, it will do so PERFECTLY - !
apparently a VISIBLE text form field - which gets typed into - and then passes
to another script into the $ENV{'QUERY_STRING'}
arrives, gets parsed, and displayed WITHOUT HITCH.
if this receiving script displays &/or enters into a DBM - you will see
I am 5'10" tall
regardless if it is displayed in the browser, or VIEWED in the dbm.
but a HIDDEN form field which is supposed to be EQ to that value -
<input type=\"hidden\" name=\"thevariable\" value=\"$thevariable\">
on that same cgi generated page , when submitted, will LOSE the
" tall
from its value in the receiving page, BOTH when displayed, or entered into
another dbm and then VIEWED.
so I conject that there is a DIFFERENCE between
a: visible form text field values (once type in and submitted)
b: hidden form field values (once generated and submitted)
either in the:
1: ride they get through the server into the $env{'query_string'}
2: ride they get during parseing out of the $env{'query_string'}
the precise same specifications and rules are followed in each part of each
series of scripts - same html, same PARSING, same everything - the ONLY
difference is outlined in a or b above. :)
1- print page with form text field
2- type in I am 5'10" tall push submit
3-parse into a $fields{'value'} so that if you code
print "$fields{'value'}\n";
you will see I am 5'10" tall on the screen
4- in the same SCRIPT code to generate a hidden form field like
<input type=\"hidden\" value=\"$fields{'value'}\" name=\"value\">
push submit
SEE? after parsing in script 5 you will see that if you
print "$fields{'value'}\n";
you will only see:
I am 5'10 NOT I am 5'10" tall
the parseing in 3 & 5 are identical, the html specs in 2,3,4,5 are identical!
I'm NOT MAKING THIS UP for crying out loud try it out for your self before you
guys flame. if the parseing is identical, and the html is the right specs AND
identical in every series of scripts and this STILL HAPPENS -
then you each owe me $5 ok?

Such as being stuck with what you affectionately like to call

If you have experience in this area, and can explain the basic options

What conflict? Do you have an example of a statement with ?? that would

The best workaround I have tested is creating a Win32::Semaphore for
each file you want to lock; I think this is the best you can do with
ActiveState's Perl. I never used any Cygnus port myself.
