Re: Can't get Socket module

Also, I do have root permission on this machine. I saw that the file that the interactive module script couldn't fetch was simply a text file that I could cut and paste with a browser.

what wrong with this code
I am writing a usr login program,
my perl are list as following.
in Line 123 what i am trying to do is if a user missing some informatin
say username, use will be prompted to input username but all other
information will be sent back to the registration form, so user do not
need to re input all the information again. (you can see my website from
http://apidb.org/regstr.html)
but this code does not work, if a user left all filed blank before he
submit, some
very strang information will be sent back to the registraiton form with
waring messge. like in the firsname field will have size=15, which is not
provided by user.

Re: what wrong with this code
Hi Xiongfei,
By looking at the source of the html, i wold suggest you wrap with quotes the default
values of the form fields (i.e attribute VALUE=)
Example:
TR
TD*Password:/TD
TDINPUT NAME='password1' Type=password ALIGN='left'
VALUE='$_[1]' SIZE='20'/TD
/TR
That way, if $_[1] is blank, the browser won't mistake SIZE='20' to be the default
value of password1.
Hope that helps,
Etienne Rivard

Re: Help really needed in this script: error: Prematue end of script header
Mel,
I agree with the follow up posting on beginners that says this script should not be
run as a CGI. However, just as an FYI, that particular error was being generated by
Apache because you weren't outputting an HTTP content type.
On another issue I see that you cross posted this message across many unrelated lists.
Including at least the datetime list. Please don't spam the Perl lists with
irrelevant questions. beginners and beginners-cgi is the appropriate place to ask
these kinds of question. The Perl community is very supportive and people in that
community want to help you. Don't alienate those that you are asking for help.
Cheers,

=head1 SYNOPSIS
nohup ./renamer image /home/httpd/htdocs /home/me/images jpg
=head1 DESCRIPTION
#The above instructs renamer to look for files called image.jpg in
/home/httpd/htdocs.
#It checks once per minute for such a file to appear. If it sees a
#readable file called /home/httpd/htdocs.jpg it moves it to
#/home/httpd/htdocs/image.200302251530.jpg where the number is a
#time stamp with year (four digits), month, day of the month, hour (in
#24 mode), and minute.
#Read the bugs section closely.
=head1 BUGS
#The original and new directories must be on the same file system.
#The program probably does not work on windows systems.
#The daemon behavior is weak.
#Not much testing has been done, so the script may have other problems.

Hi.
I don't know wvdial, but it sounds to me very much like
an application that will prompt for input. If so, then
just running it from Perl will make it start and wait -
it will only fall back to Perl when it exits. If this is
the case then you have (at least) two options:
put all of the required parameters on the command
line that you issue, or open a pipe to it and send
commands that way.

Well I think it's likely that you'd want to do:
$data =~ m/ ([^]*) /x or die Malformed data;
or at least:
$data =~ m/ ([^]*) /x or next;
as a mismatch inmplies that something's happening that
you don't expect. But you're quite right, I should have
pointed out that $1 etc. are 'sticky' and will keep their
values from the last successful match. I'll go for:

$newdata = $1 if $data =~ m/ ([^]*) /x;

DBI and getting values from the DB
Hello everyone,
Please forgive in advance if this has already been posted...fairly new
to the list as have only been on it a week. At this point I only get the
digest, but just sent an email to subscribe to the full list.
I'm running apache 2.0x with mod_perl on a windows 2000 server.
I have a form page on the website where folks can enter a name and then
search a DB looking for that name and then give back the results on
another htm page. I'm hoping this is a common thing to do.
Ok...the upshot is that using DBI:ODBC to access the access db works.
Also, I can use CGI.pm and know that the value from the form is getting
to the script.
The problem lies in comparing the values from the form and the values
from the DB. I keep getting no results.
Here's a snippet of the code:
#The CGI.pm module will take input from the form.
use CGI qw(:standard );

it like so

I also have tried..
if( $choice == 1){
`wvdial`;

but nothing after `wvdial` gets ran.
could someone offer me some advice...please :) ?
Backticks and system will run the program until
it finishes, then return control to the calling program.
Exec will run the program, but never return control.
What you want to do is fork and exec
if($pid = fork() == 0)
{
exec(wvdial);
}
# this is all executed in the parent
#...
kill $pid; #to terminate wvdial
You can check whether the connection is
good by checking the file /var/run/ppp0.ip

Subject: DBI and getting values from the DB
Hello everyone,
Please forgive in advance if this has already been
posted...fairly new to the list as have only been on it a
week. At this point I only get the digest, but just sent an
email to subscribe to the full list.
I'm running apache 2.0x with mod_perl on a windows 2000 server.
I have a form page on the website where folks can enter a
name and then search a DB looking for that name and then give
back the results on another htm page. I'm hoping this is a
common thing to do.
Ok...the upshot is that using DBI:ODBC to access the access
db works. Also, I can use CGI.pm and know that the value from
the form is getting to the script.
The problem lies in comparing the values from the form and
the values from the DB. I keep getting no results.
Here's a snippet of the code:
#The CGI.pm module will take input from the form.
use CGI qw(:standard );
my $name=param(name);
#Connecting to DB
my $dbh = DBI-connect('DBI:ODBC:opal') or die Oops!
Couldn't Connect. DBI-errstr; my $sth = $dbh-prepare
('SELECT ContactName FROM Contacts WHERE
ContactName=?')
or die Couldn't prepare the statement: . $dbh-errstr;
my @row;
#DB now connected. Run statements to find information.

RE: Module listing
You can use the find command to find all of the .pm files in the INC
dirs listed with perl -V.
Do you need to check somehow if a module is installed before running a
script?
This should work to check in your script:
eval {
require foo.pm;
import foo.pm;
}
if ($@) { die foo.pm not installed? }

In your sample script, it is when you set reprt that the \'s are being interpolated.
Add use strict, use warnings and you will see this, identified by the warnings. Are
you sure when you have retrieved the variable it still contains the backslashes? You
can test for this:
if ($reprt =~ /\\/) {
# has backslashes
}
else {
# doesn't
}
My suspicion is that it is getting interpolated somewhere between the database and
when you retrieve it, is it possible to check this path?

cpan problems
Sometimes I really hate using cpan. It's 'help' isn't much. It's been since last october that I touched my cpan stuff, and now it's out of date. It's currently at v1.60. I wanted to upgrade, so I did a make Bundle::CPAN, which is supposed to do a get first. BUT, my cpan thinks that it needs to get v1.63, Can't open CPAN-1.63.tar.gz: No such file or directory Bad luck... Still failed!

One more question - if I finally get Bundle::CPAN upgraded to the latest and greatest, will that also update my static lists on what is available on CPAN? I tried to get File::Slurp, and it wants to get an older version that no longer exists - same as the cpan bundle.

RE: removing elements from an array
You don't want to use shift in the middle of a for or foreach. shift
removes the first element of the array, and you're just asking for trouble
mucking with the structure of an array as you're cycling through it.
delete() won't work either, as it pretty much just marks the element as
undef and doesn't really remove it. I think you want something closer to
this:
@bag_quantity = grep( whatever... );
check out perldoc -f grep

I haven't looked at this much, but I'm betting it has to do with
the fact you use several different my'ed versions of the scalar
'$sheet' throughout. Try naming them something unique based upon
what they hold and I bet you'll work your own problem out.

Backticks and system will run the program until

Exec will run the program, but never return control.
What you want to do is fork and exec

You can check whether the connection is

Help with File Handle --thanks
I thank those who have answered my request--let me see if I can summarize the recommendations: David Wagner recommended that I reform the call using cp: . use File::Copy cp; $n=FileHandle-new(/dev/null,r); cp($n,x);' which is not what you are trying. You are trying to use an already open file and that I don't believe is the context of what I see in the doc. The group can correct me ( and they will) if I am wrong. ... To which Rod Dixon replied that this suggestion would only read from a dev/null. Rod also added that I can't use the move command referencing a File Handle because (1) the File Handle's contents were still buffered and (2) this command can't succeed because I won't be able to delete a still open file handle using a move. (By the way, at this point in the program I hadn't written the file handle to a file with a close, else I wouldn't have tried this approach at all). Joseph Newton affirmed Dixon's point and essentially said that I was crazy to want to copy or move a file handle even if I could. What I thought I could do based on the documentation of File::Copy was copy OR move a file handle regardless of the mode used to open it originally or whether it'd been flushed---I had my reasons, including the intention to write the results of the program's standard error and some other history to a log file locally and to concatenate that local logfile into a separate consolidated log file. I thought using File::Copy would allow me to forego all the connection overhead associated with FTP --since all remote servers and the destination server are Win-based, plus allow me to send multiple files a la move without having to remove the files successfully copied. Whether this approach is good design or not, I'll reconsider based on the feedback, but there was a method to my madness. As I said originally, wheh I read this snippet from the File::Copy documentation, it appeared to me that it is possible to copy/move a FH--no one has told me exactly why file:copy with a FH isn't possible if it works as intended- : --File Copy doc snippet begins here copy(file1,file2); copy(Copy.pm,\*STDOUT);' move(/dev1/fileA,/dev2/fileB); use POSIX; use File::Copy cp; $n = FileHandle-new(/a/file,r); cp($n,x);' DESCRIPTION The File::Copy module provides two basic functions, copy and move, which are useful for getting the contents of a file from one place to another. * The copy function takes two parameters: a file to copy from and a file to copy to. Either argument may be a string, a FileHandle reference or a FileHandle glob. Obviously, if the first argument is a filehandle of some sort, it will be read from, and if it is a file *name* it will be opened for reading. Likewise, the second argument will be written to (and created if need be). Trying to copy a file on top of itself is a fatal error. end of quoted documentation So I thought that using a FileHandle was permissible as a move, copy or cp command. I wasn't trying to write to another File Handle so it looked acceptable. I will forego this approach and close my log file, and use Net::FTP or File::Copy against the files created. Thanks all.

Can't fork using open
I've used Win32::Process to do what you're trying to do-esp. when I wanted a process to go off and do it's thing independently, then return immediately to the calling Perl module for other functions and housekeeping. Backticking and system calls didn't do what I wanted to do, esp. when the forked process was not guaranteed to return in any set time. Win32:Process does that plus a host of other process controls. -Original Message- From: Kipp, James [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 05, 2003 2:14 PM To: 'Rob Dixon'; [EMAIL PROTECTED] Subject: RE: Can't fork using open Not sure if you got an answer to this, but you can not fork opens in Win32 does not work like unix. No, but given that a lot of work has been put into ithreads in V5.8 to make threading platform-independent (or at least functional on Windows) I'm surprised that a language feature like this hasn't been implemented. As well as that I can see nowhere in the docs where it mentions the lack of Windows support for this feature. I suppose it could be dependent on the options enabled in the Perl build, which are fixed for ActivePerl because it is a binary distribution. I'd be interested to hear if anybody has any knowledge in this area. I do believe you can fork a child with an open in Win, but i am not sure if it was just a matter of syntax or something else.

the forked process doesn't seem to return or at least in any set time. The

RE: How to look into every subdirectory
I need to make an HTML page that lists all files and
directories and then links to them. The following script,
with a subroutine, looks like what I need. I should just
need to add some html tags to the Print statements.
Does that sound right to you all? Or do you have better
suggestions? (I'm a real beginner at Perl, but my job has
suddenly starting requiring lots of perl scripts!)
Sounds like a cool job!
Here's what I'd do to get a list of links to all the
files and directories and make an html page out of it ::
#!/usr/bin/perl
use strict;
use warnings;
use CGI qw/:standard/;
use File::Slurp;
my $dir = '.'; # hardcoded, from input, from function like cwd(), etc...
print header();
my @files = read_dir($dir);
foreach my $f(@files) { print \\#149\; a href=\$f\ $f /a br \n; }
Then from there you can get fancy like checking for the file type and displaying
different icons for each one,
Having alist of files/types to not display links to, taking directories and making a
list of files with links in each of them also, and on and on.
You could also add a header and footer tyo make it look ike the rest of your site
Perl is awesome!!

Just use a recursive subroutine to traverse your directory

traverse (cwd());
sub traverse

$dir .= '/' unless $dir =~ m{/$};
opendir (DIR, $dir) ||

print dir: $di\n;
traverse ($di);
}
for my $item (sort @contents) {
my $di = $dir$item;

RE: using ParseExcel::Simple to get worksheet name
im trying to use Spreadsheet::ParseExcel::Simple to return
the name of the worksheet. but all i get is something such as:
Spreadsheet::ParseExcel::Simple::_Sheet=HASH(0x39b8918)
what am i doing wrong?
It's returning a reference to a hash it looks like.
I've never used that module so I couldn't tell you for
sure but try somehting like I have below ::
code:
use strict;
use Spreadsheet::ParseExcel::Simple;
my $wkbook = x:/traffic/temp_assay/site.xls;
my (@sheets,$dest,$sheet,$year,$date,@wktemp,$ath,$bth,$cth);
my $xls = Spreadsheet::ParseExcel::Simple-read($wkbook);
foreach my $sheet ($xls-sheets) {
@sheets = $xls-sheets;
Why do you set the list of sheets when you're inside a loop working on one sheet ?
I see why you were trying it but then you just use the first element in it every time.
I'd move it before the foreach statemen so it only has to run sheets() once instead of
once for every sheet
while ($sheet-has_data) {
my @data = $sheet-next_row;
my $sheet = $sheets[0];
print $sheet\n;
print ${$sheet}{$sheets[0]};
this may or may not do it since I'm not familiar w/ the module but it's the right
idea.
You need to see the module's docs about how it sets up references and perhaps brush up
on understanding perl refernces. They will help you out very much.

Re: Managing the backslash in a string
Guy P wrote: Look at the small program below. The result is this: DirectionsNitprogrsourcsql DirectionsNitprogrsourcsql And I would like it to be this:\Directions\unit\progr\sourcsql ... $reprt= \Directions\unit\progr\sourcsql; ...Hi Guy, You are comparing apples and oranges here. The string in $reprt above is not equivalent to what the variable would hold if you got it from the database. My Perl program execute a query that bring back into a variable a Windows paths initially stored in a database. I have got problems to manage the backslash. To express what the variable would hold if read from the database, you would have to escape each backslash with another backslash. All control characters within interpolated strings require backslashes to escape them. This makes the packslash itself a control character. Each backslash must then be escaped. Solutions: Escape each backslash: $reprt = Directions\\unit\\progr\\sourcsql; OR use a non-interpolated [single-quoted] string: $reprt = 'Directions\unit\progr\sourcsql'; OR skip trying to hard-code the string in a variable, and instead test by reading the string from the command line. If you do this, there will be no need to escape control characters, as that will already be done under the surface. Joseph OT: You might note that I also removed the initial backslashes. If you are working in Windows, there is no context in which they will be needed. If you have a tree structure: C:\ biology\ botany\ zoology\ protozoan.txt echinoderm.txt Your current directory is biology. to access echinoderm.txt in the zoology folder you would address it as zoology\echinoderm.txt, with no initial control characters of any kind. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Behavior of this function varies wildly depending on your system
implementation. For example, it will usually not work across file system
boundaries, even though the system Imv command sometimes compensates
for this. Other restrictions include whether it works on directories,
open files, or pre-existing files. Check Lperlport and either the
rename(2) manpage or equivalent system documentation for details.

Re: Script does not want to run, error
Make sure your script starts with #!/path/to/perl then change permission of the script, chmod 755 file_to_set try to run your script, if it doesnt work try #perl file_to_run Mark - Original Message - From: mel awaisi [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, March 05, 2003 5:11 PM Subject: Script does not want to run, error Hi, I am having problems opening this script on my machine. i have been getting help from a very helpful person on this list.

Hi Jeff,
The code you have looks fine, presuming both fiiles are in the current directory. It
might help to see more of the context. Have you tried pritning both filenames, as
well as checking the tmp file before and after running the script to ensure that it
has been modified?

Re: rename() doesn't work
Yes, I tried all that. (thanks)
This is very odd... turns out that when I tried to do a regular 'mv' command
under Unix, it too said success ($?=0) I found that the mount I have
my file system is non-standard Unix, so while the OS thought everything was
okay, it really wasn't. I'm using some HP proprietary network mount.
Go figure %-/

[OT] YAPC::NA 2003 Registration
Hello folks, I just wanted to alert people to the fact that registration has begun for YAPC::NA::2003. The Yet Another Perl Conferences (YAPCs) are grassroots symposia on the Perl programming language under the auspices of the Yet Another Society (YAS), a non-profit corporation for the advancement of collaborative efforts in computer and information sciences. The cost is $85 for 3 days of talks, tutorials and discussions. I have some fabulous talk proposals, so this stands to be a great place to learn some new things. It will be June 16-18, 2003 in Boca Raton, FL. Please visit the website to learn more, and _to register_. If anyone has any questions, feel free to email me off-list.

regex fun :)
hello,
while trying to get a grasp on regex
i found this nice little tutorial.
http://www.steve.gb.com/perl/lesson06.html
so i tried this..
$choice = 11
if($choice =~ /[1-6]{1}/)
this returns true. I want it to only match
a single digit ranging 1-6 , I thought
the {1} would specifiy to match one time only??
could someone tell me what im doing wrong :) ?
Thanks,

The {1} does tell it to match one time only, match any character 1-6 one
time only, but not match only 1 character from 1-6 :-)..., so it matches
the first '1' in the string and that is success.
How about,
if ($choice =~ /^[1-6]$/) {
}

[1-6]{1} is a more verbose way of saying [1-6]. {1} is implied with
every character literal or character class. You COULD write /string
[1-6]/ as /s{1}t{1}r{1}i{1}n{1}g{1} {1}[1-6]{1}/ but why would you want
to?
this returns true. I want it to only match
a single digit ranging 1-6,
You need to learn about anchors. The beginning of line anchor - ^, the
end of line anchor - $, the beginning of string anchor - \A, and the end
of string anchors - \z and \Z
I thought
the {1} would specifiy to match one time only??
could someone tell me what im doing wrong :) ?
It does match one time only but because the regex is not anchored it
will match one character anywhere in the string. If you anchor the
regex to the beginning of the line AND to the end of the line then there
is no way that the string can contain more characters then your regex
specifies.
my $choice = 11
if ( $choice =~ /^[1-6]$/ )
