Hello everyone :-) ,
I am a newbie to Perl, but have
experience with other scripting languages. I am putting up this post
to ask for advice regarding what skills I would need to get a task
done. This might not be the most appropriate group, but since Perl is
used a lot for server back-end scripts, I guess a lot of people have
experience with using it for building web applications.

My task: I have bought a domain and now want to set up a website on
it.

What will the site do: Accept a string from the user, like Google does
(A very simple design). Then the site will check this string for the
presence of a substring. The output will be displayed in a simple text
box on the main page (to begin with).

If I have a script that will do this operation, I need to link the
input string to this script in the background and return the result.
Is CGI programming used to make this "glue" ? I could ask someone to
access the script directly on my site like

3.16: How can I make my Perl program take less memory?

When it comes to time-space tradeoffs, Perl nearly always prefers to
throw memory at a problem. Scalars in Perl use more memory than strings
in C, arrays take more than that, and hashes use even more. While
there's still a lot to be done, recent releases have been addressing
these issues. For example, as of 5.004, duplicate hash keys are shared
amongst all hashes using them, so require no reallocation.

Hi,

I'm trying to write perl in windows environment and need to use the
package win32::mmf. Anyhow, I've got some test code below that will
write to the windows namespace but will not retrieve from it. Please
note it's just an example in production I would be writing to the ns
in one script and grabbing from the ns in another.

For some reason the second instance of mmf is not accessing the same
namespace. Any ideas?

my $mmf = Win32::MMF->new( -swapfile => "data.swp",
-namespace => "MyDataShare",
-size => 1024 * 1024 )
or die "\n\n\n\nCan not create namespace";

$mmf->setvar($tokenKey, $hashRef);
print "\n\n " . $mmf->debug();

print "\n\n
--------------";

undef $mmf;
my $mmf = Win32::MMF->new( -swapfile => "data.swp",
-namespace => "MyDataShare",
-size => 1024 * 1024 ,

I'm trying to find "the" method, using SOAP::Lite or SOAP::Schema,
to get a WSDL that requires HTTP authentication.

The only way I've been able to get a WSDL that requires basic
authentication is by over-riding the SOAP::Schema::access method:

e.g.

use SOAP::Lite;

my $login = 'mylogin';
my $pw = 'mypassword';

my $service = SOAP::Lite
-> service( 'http://some.server.com/some/protected/path/my.wsdl' );
#$service->some_method();

# over-ride method to handle authentication
sub SOAP::Schema::access
{
my $self = shift->new;
my $url = shift || $self->schema_url || Carp::croak 'Nothing to
access. URL is not specified';

my $req = HTTP::Request->new(GET => $url);

3.14: How can I write a GUI (X, Tk, Gtk, etc.) in Perl?

(contributed by Ben Morrow)

There are a number of modules which let you write GUIs in Perl. Most GUI
toolkits have a perl interface: an incomplete list follows.

Tk This works under Unix and Windows, and the current version doesn't
look half as bad under Windows as it used to. Some of the gui
elements still don't 'feel' quite right, though. The interface is
very natural and 'perlish', making it easy to use in small scripts
that just need a simple gui. It hasn't been updated in a while.

We need to fill, submit and test the response of a WEB form. This was
we can check the backend databases are working and the forms are
functioning.

Is there a way to have perl interact with a standard form and monitor
the resposes?

Maybee a standard script or something already developed, but otherwise
a basic outline of a method that would work.

Many thanks
Gary

3.12: Where can I get perl-mode for emacs?

Since Emacs version 19 patchlevel 22 or so, there have been both a
perl-mode.el and support for the Perl debugger built in. These should
come with the standard Emacs 19 distribution.

In the Perl source directory, you'll find a directory called "emacs",
which contains a cperl-mode that color-codes keywords, provides
context-sensitive help, and other nifty things.

Note that the perl-mode of emacs will have fits with "main'foo" (single
quote), and mess up the indentation and highlighting. You are probably
using "main::foo" in new Perl code anyway, so this shouldn't be an
issue.

Greetings,

I am trying to append an alphabetical counter to a string. But
concatenation shows a very strange behaviour in this case. Can some
one please help?

The piece of code looks like :

$self->{"log"}->debug(" In Function _process_array_data. ");
$self->{"log"}->debug(" temp 4,data[11],ctr value s are : $temp-

$temp->[4] = substr($data->[11],0,2).substr($data-

$self->{"log"}->debug(" temp 4 value is : $temp->[4] ");

And output in debug file is something like this :

DEBUG: temp 4,data[11],ctr value s are : , NX200802118966, the
counter value is : AA
DEBUG: temp 4 value is : NX02118966 the counter value is : AA

And in output file the record comes like :

211012 00003855 1992 NX02118966
